Abstract:
An apparatus for quickly, easily and adjustably connecting elevator car and counterweight guide rail support brackets to the walls of an elevator hoistway and also to either vertically or horizontally extend structural beams that are disposed within the elevator hoistway. Installation of the apparatus requires no welding operations to be performed in order to connect the brackets to the walls or to the beams. The apparatus uniquely includes cooperating support and connector brackets each of which has a plurality of strategically arranged, indexable connector holes that permit the necessary degree of adjustment of the brackets to properly position the guide rails within the hoistway.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a method and apparatus for mounting within an elevator shaft counterweight rails or guide rails for elevator cars. More particularly, the invention concerns a mounting system in which the guide rails are adjustably attached to one or more intermediate beams that are disposed within the elevator shaft. 
     2. Discussion of the Prior Art 
     A typical prior art electric power elevator system has an elevator shaft or hoistway within which guide rails are mounted to guide the vertical travel of elevator cars and counterweights. In many instances in prior art construction, intermediate beams are used to divide an elevator shaft into two or more parts forming channels for separate cars moving along guide rails attached to intermediate beams. Guide rails for counterweights can also be mounted on the intermediate beams. 
     In the past, the guide rails for elevator cars or counterweights were secured to the intermediate beams using various bars and plates that were secured to the beams by welding. This prior art installation technique is both cumbersome and time consuming even in new construction. However, in retrofit constructions, the technique is particularly difficult. For example, when the elevator systems in hospitals, schools, and other public buildings are retrofitted, the welding step is quite hazardous and most undesirable. This is because, during the retrofit operations, welding of the rail brackets to the support brackets results in noxious welding gases and fumes unavoidably spreading throughout the building. Particularly in hospitals and schools, these noxious welding gases can be both unpleasant and hazardous and can, on occasion, result in serious complications to the persons exposed to the noxious fumes. 
     This major drawback of the prior art processes was largely overcome by the novel methods and apparatus described in U.S. Pat. No. 6,196,356 issued to the present inventor. The present invention seeks to improve upon the apparatus described in the earlier patent by providing uniquely configured, readily adjustable support and guide rail brackets that can be safely and securely interconnected with beams disposed within the elevator hoistways that house the elevator systems. 
     As will be better understood from the description, which follows, the apparatus of the present invention includes novel beam interconnection means for interconnecting the rail support brackets with both vertically and horizontally extending beams. Additionally, in certain instances, the connector legs of the support and guide rail brackets of the apparatus are provided with a plurality of strategically arranged, indexable connector holes that permit the necessary degree of adjustment of the brackets to properly position the guide rails within the hoistway. When selected pairs of connector holes provided in the brackets are appropriately aligned, the brackets can be securely bolted together using specially configured bolts that provide substantial structural integrity and positively preclude shifting of the brackets even as a result of projected seismic loading. In other instances, novel brackets of various configuration are used to adjustably attach the guide rails to one or more walls that cooperate to define the elevator hoistway. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a novel method and apparatus for quickly, easily, and adjustably connecting elevator car and counterweight guide rail support brackets to either vertically or horizontally extending structural beams that are disposed within an elevator hoistway of a building. 
     Another object of the invention is to provide a novel method and apparatus for quickly, easily, and adjustably connecting elevator car and counterweight guide rail support brackets to the sidewalls of an elevator hoistway of a building. 
     Another object of the invention is to provide a method of the aforementioned character, which requires no welding operations to be performed in order to connect the brackets to the beams. 
     Another object of the invention is to provide connector brackets of the character described which include cooperating support and connector brackets each having a plurality of strategically arranged, indexable connector holes that permit the necessary degree of adjustment of the brackets to properly position the guide rails within the hoistway. 
     Another object of the invention is to provide an apparatus as described in the preceding paragraphs that includes specially configured connector bolts that provide substantial structural integrity and positively preclude shifting of the brackets even as a result of projected seismic loading.

     DESCRIPTION OF THE INVENTION 
     Referring to the drawings and particularly to FIGS. 1A and 1B, several forms of the connector apparatus of the present invention for interconnecting guide rails in elevator systems with various types of structural components is there illustrated. In the area of FIG. 1A designated by the letter A, a connector apparatus for interconnecting the guide rails of a counterweight system with two pair of vertically extending columns is there illustrated. Shown in the area designated by the letter B in FIG. 1B is a connector apparatus for interconnecting the guide rails of a counterweight system with one wall of the building structure that houses the elevator system. In the area of FIG. 1A designated by the letter C there is shown a connector apparatus for interconnecting a guide rail of an elevator system with one wall of the building structure that houses the elevator system. In the area designated by the letter D in FIG. 1A is a connector apparatus for interconnecting the guide rails of an elevator system with a pair of vertically extending columns. Shown in the area designated by the letter E in FIG. 1B is a connector apparatus for interconnecting the guide rails of an elevator system with a horizontally extending beam, In the area designated by the letter F in FIG. 1B is another form of connector apparatus for interconnecting the guide rail of an elevator system with a pair of vertically extending columns. 
     Considering first the connector apparatus shown in the area of FIG. 1A that is designated by the letter A, this connector apparatus comprises two identical connector assemblies  15  that function to interconnect the guide rails R of a counterweight system with structural components, here comprising two pair of vertically extending beams or columns generally designated by the numerals  14  and  14   a . Referring to FIG. 2, where the construction of one of the two identical connector assemblies  15  is illustrated, each connector assembly  15  of this form of the invention can be seen to comprise first, second, third, and fourth spaced-apart right angle brackets  16 ,  18 ,  20 , and  22  respectively. Each of the first and second spaced-apart angle brackets  16  and  18  has a first generally planar, outwardly extending leg  24  that has an aperture  26  formed therein and a second perpendicularly extending second leg  28  that has an aperture  30  extending there through. 
     Also forming a part of the connector apparatus of the invention is a first elongated spanner plate  32  that spans the spaced-apart, vertically extending columns  14 . Plate  32  has a first face  32   a  that engages the outer face of the columns  14  and a second face  33   b  that engages faces  28   a  of the angle brackets  16  and  18 . Interconnecting the first legs  24  of first and second angle brackets  16  and  18  is a tie bolt  36 . Tie bolt  36  extends through the apertures  26  formed in legs  16  and  18  and is secured in position by a locking nut  39 . In the present form of the invention, angle brackets  16 ,  18 ,  20  and  22 , along with spanner plate  32 , comprise the interconnection means of the invention for adjustably interconnecting a first connector bracket, that is generally designated in the drawings by the numeral  42 , with the structural components which here comprise columns  14  and  14   a.    
     Disposed in engagement with faces  14   b  of the vertically extending beams  14  is the first leg  42   a  of first connector bracket  42 . As illustrated in FIG. 2, leg  42   a  is disposed between faces  14   b  of columns  14  and faces  20   a  and  22   a  of angle brackets  20  and  22  respectively. A second tie bolt  46  interconnects the first legs  20   b  and  22   b  of third and fourth angle brackets  20  and  22 . Tie bolt  46 , that has a threaded end  46   a , extends through apertures  20   c  and  22   c  formed in legs  20   b  and  22   b  of the angle brackets  20  and  22  and is secured in position by a locking nut  47 . 
     In order to urge leg  42   a  of connector bracket  42  into secure engagement with columns  14 , third and fourth eyebolts  50  and  52  are interconnected with the angle brackets in the manner shown in FIG.  2 . More particularly, eyebolt  50  functions to interconnect leg  28  of first angle bracket  16  with leg  20   d  of second angle bracket  20 , while eyebolt  52  functions to interconnect leg  28  of second angle bracket  18  with leg  22   d  of fourth angle bracket  22 . Eyebolt  50 , that has a threaded end  50   a , extends through an aperture  20   e  formed in bracket  20 , through an aperture  43  formed in leg  42   a  of bracket  42 , through an aperture  32   b  formed in spanner plate  32  and finally through the aperture  30  formed in leg  28  of angle bracket  16 . Eyebolt  50  is held in position by means of a locking nut  53 . In similar fashion, eyebolt  52 , that has a threaded end  52   a , extends through an aperture  22   e  formed in leg  22   d  of bracket  22 , through an elongated aperture  55  formed in leg  42   a  of connector plate  42 , through an elongated aperture  32   c  formed in spanner plate  32  and finally through the aperture  30  formed in leg  28  of angle bracket  18 . Eyebolt  52  is held in position by means of a locking nut  57 . Elongated apertures  55  and  32   c  permit longitudinal adjustment of brackets  18  and  22  to accommodate for variations in the spacing of columns  14 . 
     As best seen in FIG. 4, first connector bracket  42  has a second leg  42   b  that extends generally perpendicularly to leg  42   a . Formed within second leg  42  of connector bracket  42   b  are first and second sets of through holes  59  and  61 , the purpose of which will presently be described. Holes  59  are disposed along a first line  62  that extends at an acute angle with respect to first leg  42   a  of connector bracket  42 . Similarly, through holes  61  are disposed along a second line  64  that extends at an acute angle with respect to first leg  42   a  of connector bracket  42 . Each of the through holes  59  and  61  are generally rectangular in plan and are of a size and shape to closely receive the square shank portion of threaded connector bolts which, in a manner presently to be described, are used to interconnect a second connector bracket  66  with bracket  42 . 
     Second connector bracket  66 , which functions to adjustably support one of the counterweight rails “R”, is adjustably interconnected with first connector bracket  42  in a manner now to be described. Like bracket  42 , connector bracket  66  is provided with first and second sets of through holes  67  and  69 . Holes  67  are disposed along a third line  70  that extends at an acute angle with respect to first leg  66   a  of connector bracket  66  and also angularly with respect to line  64 . Similarly, through holes  69  are disposed along a fourth line  71  that extends angularly with respect to first leg  66   a  of connector bracket  66  and also angularly with respect to line  62 . Each of the through holes  67  and  69  are also generally rectangular in plan and are of a size and shape to closely receive the square shank portion of the threaded connector bolts. 
     Through holes  67  formed in bracket  66  are so constructed and arranged that a selected one of the through holes  67  can be moved into index with a selected one of the through holes  61  formed in bracket  42  by a sliding movement of bracket  66  relative to bracket  42 . Similarly, through holes  69  formed in bracket  66  are constructed and arranged so that a selected one of the through holes  69  can be moved into index with a selected one of the through holes  59  formed in bracket  42  when bracket  66  is moved from a first position to a second position relative to bracket  42 . More particularly, bracket  66  can be slidably moved relative to bracket  42  in a first transverse direction generally parallel with leg  42   a  of bracket  42  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  42   a  of bracket  42 . 
     When second connector bracket  66  is correctly aligned with first connector bracket  42  and a selected one of the though holes  67  is indexably aligned with a selected one of the through holes  61 , a first connector bolt, such as a bolt  72 , can be introduced into the aligned through holes. Similarly, when the connector bracket  66  is correctly aligned with bracket  42  and a selected one of the through holes  69  is indexably aligned with a selected one of the through holes  59 , a second bolt, such as connector a bolt  73 , can be introduced into the aligned through holes. With the bolts  72  and  73  in position with the square shank portions  73   a  thereof (FIG. 4) closely received within the aligned holes, nuts such as nut  77  can be used to securely interconnect connector bracket  66  with bracket  42  in the manner shown in FIGS. 2 and 3. When the brackets are thusly connected, the square shaped shank portions  73   a  of the bolts will be snugly received within the indexably aligned through holes in the two brackets and will efficiently prevent sliding movement between the brackets even under severe seismic loading. 
     Also forming a part of the connector apparatus of the form of the invention shown in FIGS. 1A and 2 are rail connector means for adjustably interconnecting the guide rail “R” of the counterweight system to leg  66   a  of second connector bracket  66 . In the present form of the invention, this connector means comprises a pair of spaced apart connector clips  74  that are adjustably connected to second legs  66   a  of connector bracket  66  by threaded bolts  75 . Each connector clip  74  has a rail engagement leg  74   a  that is adapted to clampingly engage the legs R- 1  of the guide rail R. 
     It is to be noted that second leg  66   a  of connector bracket  66  is provided with spaced-apart, outwardly extending walls  76  and  76   a , each of which is provided with a bore  77  that is adapted to receive the shank of a threaded jackbolt  78 . Jackbolts  78  are threadably received within an adjustment nut  79  that is connected to each of the jackbolts. Adjustment nuts  79  bear upon the outer surface of walls  76  so that, when the jackbolts are threaded inwardly and outwardly with respect to nuts  79 , clips  74  can be adjusted longitudinally of leg  66   a . In this regard, each of the jackbolts  78  terminates in an end  78   a  that is in engagement with a selected one of the connector clips  74  so that by loosening bolts  75  and threading the jackbolts inwardly and outwardly relative to nuts  79 , clips  74  can be moved into and out of clamping engagement with legs R- 1  of rail R. To permit this adjustment, leg  66   a  of bracket  66  is provided with a pair of spaced-apart slots  66   b  that accept the shank portion of the connector bolts  75 . It is apparent that by loosening locking nuts  80 , clips  74  can be moved toward and away from guide rail R in the direction of the arrows of FIG.  2  and can be securely locked in position by tightening jack bolts  78  and then by retightening locking nuts  80 . It is to be understood that when the apparatus of the invention is installed within the hoistway in the manner shown in FIG. 1A, the various degrees of adjustment available to the installer permits the installer to precisely locate the guide rails R in an optimum position to permit smooth and efficient operation of the counterweight system. 
     Referring next to FIGS. 5 through 7, one of the two connector assemblies  82  shown in area “B” of FIG. 1B is shown in enlarged form. As indicated in FIG. 1B, this alternate form of the connector apparatus of the invention is used for interconnecting a pair of guide rails of a counterweight system with a structural component, here comprising a supporting structure such as a wall W- 1  of the structure that houses the elevator hoistways. As best seen in FIG. 5, each of the connector assemblies  82  of this latest form of the invention comprises a first connector bracket  84  having a first generally planar first leg  86  that is connected to the supporting structure W- 1  by interconnection means, the character of which will presently be described. Leg  86  extends generally perpendicularly from a second leg  87  that has a generally planar surface  87   a . Leg  86  is provided with four spaced-apart apertures  88 ,  90 ,  92  and  94 . Received within apertures  90  and  92  are the threaded shank portions  96   a  of a pair of anchor bolts  96 , the body portions  96   b  of which are embedded within the concrete of the supporting wall W- 1 . The threaded shank portions  96   a  of bolts  96  extend through apertures  90  and  92  and are interconnected with leg  86  of bracket  84  by locking nuts  100  respectively. 
     Receivable within apertures  88  and  94  are a pair of threaded jackbolts  104  and  106 . The extremities of each of the jackbolts  104  and  106 , which are generally designated by the numerals  104   a  and  106   a  respectively, are adapted to pressurally engage the external surface of the supporting wall W- 1  in the manner shown in FIG.  5 . Jackbolts  104  and  106  are each threadably received within an adjustment nut  110  that is connected to each of the jackbolts. Adjustment nuts  110  bear upon the outer surface  86   a  of leg  86  of bracket  84  so that, when the jackbolts  104  and  106  are threaded inwardly and outwardly with respect to nuts  110 , first bracket  84  can be adjustably moved relative to the outer surface of support wall W- 1  in a manner to adjust the spacing of first bracket  84  relative to the support wall W- 1 . 
     Anchor bolts  96  and jack bolts  104  and  106  comprise the interconnection means of this form of the invention for adjustably interconnecting bracket  84  with the structural component or wall W- 1 . 
     Second leg  87  of bracket  84  is provided with a plurality of first through holes  112  that are disposed along a first line  114  that extends at an acute angle with respect to first leg  86 . Similarly, leg  87  is provided with a second set of first through holes  116  that are disposed along a second line  118  that extends at an acute angle with respect to first leg  86 . 
     Adjustably interconnected with first connector bracket  84  is a second connector bracket  120 . Second bracket  120  has a first leg  122  and a second leg  124  that extends generally perpendicular to first leg  122 . As illustrated in FIG. 5, first leg  122  is provided with a pair of spaced-apart, outwardly extending side walls  126  and  128  each of which is provided with a bore  130 , the purpose of which will presently be described. 
     As best seen in FIG. 7, second bracket  120  is also provided with a plurality of through holes  132  that are disposed along a third line  133  that extends at an acute angle with respect to first leg  122  and with respect to line  118 . Similarly, leg  124  is provided with another set of through holes  134  that are disposed along a fourth line  136  that extends at an acute angle with respect to first leg  122  and with respect to line  133 . Through holes  132  formed in bracket  120  are so constructed and arranged that a selected one of the through holes  132  can be moved into index with a selected one of the through holes  112  formed in bracket  84  by a sliding movement of bracket  120  relative to bracket  84 . Similarly, through holes  134  formed in bracket  120  are constructed and arranged so that a selected one of the through holes  134  can be moved into index with a selected one of the through holes  116  formed in bracket  84  when bracket  120  is slidably moved from a first position to a second position relative to bracket  84 . More particularly, bracket  120  can be slidably moved relative to bracket  84  in a first direction generally parallel with leg  86  of bracket  84  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  86  of bracket  84 . 
     When second connector bracket  120  is correctly aligned with first connector bracket  84  and a selected one of the though holes  132  is indexably aligned with a selected one of the through holes  112 , a first bolt, such as a bolt  138 , can be introduced into the aligned through holes. Similarly, when the connector bracket  120  is correctly aligned with bracket  84  and a selected one of the through holes  134  is indexably aligned with a selected one of the through holes  116 , a second bolt, such as a bolt  140 , can be introduced into the aligned through holes. With the bolts  138  and  140  in position with the square shank portions  141  thereof (FIG. 7) closely received within the aligned holes, nuts such as nut  143  can be used to securely interconnect connector bracket  120  with bracket  84  in the manner shown in FIGS. 5 and 7. When the brackets are thusly connected, the square shaped shank portions  141  of the bolts will be snugly received within the indexably aligned through holes in the two brackets and will efficiently prevent sliding movement between the brackets. 
     The connector apparatus of this latest form of the invention further includes connector means for connecting the guide rails of the counterweight system shown in FIG. 1B to first leg  122  of second bracket  120  in the manner illustrated in FIGS. 5 and 6. In this latest form of the invention, the connector means comprises first and second spaced-apart connector clips  144  that are of a similar construction to the earlier identified connector clips  74 . Connector clips  144  are adjustably connected to first leg of connector bracket  120  by threaded bolts  145 . Each connector clip  144  has a rail engagement leg  144   a  that is adapted to clampingly engage the legs R- 1  of the guide rail R. Bores  130  formed in outwardly extending walls  126  and  128  of leg  122  are adapted to receive a threaded jackbolt  150 . Jackbolts  150  are each threadably received within an adjustment nut  151 . Adjustment nuts  151  bear upon the outer surface of walls  126  and  128  so that, when the jackbolts are threaded inwardly and outwardly with respect to nuts  151 , clips  144  can be adjusted relative to leg  122 . Each of the jackbolts  150  terminates in an end  150   a  that is in engagement with a selected one of the connector clips  144  so that by loosening bolts  145  and threading the jackbolts inwardly and outwardly relative to nuts  151 , clips  144  can be moved into and out of clamping engagement with legs R- 1  of rail R. To permit this adjustment, leg  122  of bracket  120  is provided with a pair of spaced-apart slots  152  that accept the shank portion of the connector bolts  145 . It is apparent that by loosening locking nuts  145   a , clips  144  can be moved toward and away from guide rail R in the direction of the arrows of FIG.  5  and can be securely locked in position by tightening jack bolts  150  and then by retightening locking nuts  145   a.    
     It is to be understood that when the apparatus of the invention is installed within the hoistway in the manner shown in FIG. 1B, the various degrees of adjustment available to the installer permits the installer to precisely locate the counterweight guide rails in an optimum position to permit smooth and efficient operation of the counterweight system. 
     Considering next the embodiment of the invention shown in area “C” of FIG. 1A, this embodiment comprises a connector apparatus for interconnecting a guide rail of an elevator system with a wall W- 2  of the building structure that houses the elevator system. As best seen in FIG. 9, the connector assembly  158  of this latest form of the invention comprises a first connector bracket  160  having a first generally planar first leg  162  that is connected to a structural component, here shown as the supporting structure W- 2 . As before, connector bracket  160  is adjustably interconnected with structure W- 2  by interconnection means the character of which will presently be described. Leg  162  extends generally perpendicularly from a second leg  164  that has a generally planar surface  164   a . Leg  164  is provided with four spaced-apart apertures  166 ,  168 ,  170  and  172 . Received within apertures  168  and  170  are the threaded shank portions  174   a  of a pair of anchor bolts  174 , the body portions  174   b  of which are embedded within the concrete of the supporting wall W- 2 . The threaded shank portions  174   a  of bolts  174  extend through apertures  168  and  170  and are interconnected with leg  162  of bracket  160  by locking nuts  177  respectively. 
     Receivable within apertures  166  and  172  are threaded jackbolts  178  and  180  respectively. The extremities of each of the jackbolts  178  and  180 , which are generally designated by the numerals  178   a  and  180   a  respectively, are adapted to pressurally engage the external surface of the supporting wall W- 2  in the manner shown in FIG.  9 . Jackbolts  178  and  180  are each threadably received within an adjustment nut  183  that is connected to each of the jackbolts. Adjustment nuts  183  bear upon the outer surface  162   a  of leg  162  of bracket  160  so that, when the jackbolts are threaded inwardly and outwardly with respect to nuts  183 , first bracket  160  can be adjustably moved relative to the outer surface of support wall W- 2  in a manner to adjust the spacing of first bracket  160  relative to the support wall W- 2 . Anchor bolts  170  along with jack bolts  178  and  180  comprise the interconnection means of this latest form of the invention. 
     Second leg  164  of bracket  160  is provided with a plurality of first through holes  186  that are disposed along a first line  188  that extends at an angle with respect to first leg  162 . Similarly, leg  164  is provided with a second set of first through holes  190  that are disposed along a second line  192  that extends at an angle with respect to first leg  162 . Adjustably interconnected with first connector bracket  160  is a second connector bracket  194 . Second bracket  194  has a first leg  196  and a second leg  198  that extends generally perpendicular to first leg  196 . As illustrated in FIG. 9, a pair of spaced-apart walls  202  and  204  extend outwardly from leg  196  and each is provided with a threaded bore  206 , the purpose of which will presently be described. 
     As best seen in FIG. 9, leg  198  of second bracket  194  is also provided with a plurality of through holes  208  that are disposed along a third line  210  that extends at an angle with respect to first leg  196  and with respect to line  188 . Similarly, leg  198  is provided with another set of through holes  212  that are disposed along a further line  214  that extends at an angle with respect to first leg  196  and with respect to line  192 . Through holes  208  formed in bracket  194  are so constructed and arranged that a selected one of the through holes  208  can be moved into index with a selected one of the through holes  186  formed in bracket  160  by a sliding movement of bracket  194  relative to bracket  160 . Similarly, through holes  212  formed in bracket  194  are constructed and arranged so that a selected one of the through holes  212  can be moved into index with a selected one of the through holes  190  formed in bracket  160  when bracket  194  is slidably moved from a first position to a second position relative to bracket  160 . More particularly, bracket  194  can be slidably moved relative to bracket  160  in a first direction generally parallel with leg  162  of bracket  160  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  162  of bracket  160 . 
     When second connector bracket  194  is correctly aligned with first connector bracket  160  and a selected one of the though holes  208  is indexably aligned with a selected one of the through holes  186 , a first bolt, such as a bolt  217 , can be introduced into the aligned through holes. Similarly, when the connector bracket  194  is correctly aligned with bracket  160  and a selected one of the through holes  212  is indexably aligned with a selected one of the through holes  190 , a second bolt, such as a bolt  219 , can be introduced into the aligned through holes. With the bolts  217  and  219  in position with the square shank portions  222  thereof (FIG. 8) closely received within the aligned holes, nuts, such as nut  224  can be used to securely interconnect connector bracket  194  with bracket  160  in the manner shown in FIGS. 8 and 9. When the brackets are thusly connected, the square shaped shank portions  222  of the bolts will be snugly received within the indexably aligned through holes in the two brackets and will efficiently prevent sliding movement between the brackets. 
     As in the earlier described embodiment, the connector apparatus of this latest form of the invention includes connector means for connecting the guide rail ER of the elevator system shown in FIG. 1A to first leg  196  of second bracket  194  in the manner illustrated in FIGS. 8 and 9. In this latest form of the invention, the connector means comprises first and second spaced-apart connector clips  228  that are of a similar construction to the earlier identified connector clips  74 . Connector clips  228  are adjustably connected to first leg of connector bracket  194  by threaded bolts  229 . Each connector clip  228  has a rail engagement leg  228   a  that is adapted to clampingly engage the legs ER- 1  of the guide rail ER. 
     Bores  206  formed in outwardly extending walls  202  and  204  are adapted to threadably receive a threaded jackbolt  232 . Jackbolts  232  are threadably received within an adjustment nut  233  that is connected to each of the jackbolts. Adjustment nuts  233  bear upon the outer surfaces of walls  202  and  204  so that, when the jackbolts are threaded inwardly and outwardly with respect to nuts  233 , the connector clips can be adjustably moved relative to leg  196 . Each jack bolt  232  has an end  232   a  that is in engagement with a selected one of the connector clips  228  so that by loosening bolts  229  and threading the jackbolts inwardly and outwardly relative to walls  202  and  204 , clips  228  can be moved into and out of clamping engagement with legs ER- 1  of rail ER. To permit this adjustment, leg  196  of bracket  194  is provided with a pair of spaced-apart slots  235  that accept the shank portion of the connector bolts  229 . It is apparent that by loosening locking nuts  229   a , clips  228  can be moved toward and away from guide rail ER and can be securely locked in position by tightening jack bolts  232  and then by retightening locking nuts  229   a.    
     It is to be understood that when the apparatus of the invention is installed within the hoistway in the manner shown in FIG. 1A, the various degrees of adjustment available to the installer permits the installer to precisely locate the guide rail ER in an optimum position relative to the elevator car EC- 1 . 
     Referring next the embodiment of the invention shown in area “D” of FIG. 1A, this embodiment comprises a connector apparatus for interconnecting the guide rails ER- 1  and ER- 2  of an elevator system with structural components shown here as a pair of spaced apart vertically extending beams or columns  250 . As best seen in FIG. 12, this connector apparatus comprises two connector assemblies  252  and  252   a  that function to interconnect the guide rails ER- 1  and ER- 2  of the elevator system with the pair of vertically extending beams  250 . 
     As shown in FIG. 12, connector assembly  252  of this latest form of the invention comprises first and second spaced-apart right angle brackets  254  and  256 . Bracket  254  has a first generally planar, outwardly extending leg  258  that has an aperture  260  formed therein and a second perpendicularly extending second leg  262  that has an aperture  264  extending there through. Bracket  256  also has a first generally planar, outwardly extending leg  266  that has an aperture  268  formed therein and a second perpendicularly extending second leg  270  that has an aperture  272  extending there through. 
     Maintained in engagement with faces  250   a  of the vertically extending beams  250  by the interconnection means of the invention is the first leg  274   a  of an elongated, first connector bracket that is generally designated in the drawings by the numeral  274 . More particularly, leg  274   a  of bracket  274  has a first face  275  that engages the outer faces of the columns  250  and a second face  277  that engages the inner faces of legs  262  and  270 . Leg  274   a  of bracket  274  is also provided with an aperture  279  and a slot  281 , the purpose of which will presently be described. Interconnecting legs  258  and  266  of first and second angle brackets  256  and  254  is a tie bolt  278 . Tie bolt  278  extends through apertures  260  and  268  formed in legs  266  and  258  and is secured in position by a locking nut  279 . In this latest form of the invention, angle brackets  256  and  258  comprise part of the interconnection means of the invention for interconnecting first connector bracket  274  with beams  250 . 
     As best seen in FIG. 12, first connector bracket  274  has a second leg  274   b  that extends generally perpendicularly to leg  274   a . Formed within second leg  274   b  of connector bracket  274  are first and second sets of through holes  282  and  284 , the purpose of which will presently be described. Holes  282  are disposed along a first line  286  that extends angularly with respect to first leg  274   a  of connector bracket  274 . Similarly, through holes  284  are disposed along a second line  288  that extends angularly with respect to first leg  274   a  of connector bracket  274 . Each of the through holes  282  and  284  are generally rectangular in plan and are of a size and shape to closely receive the square shank portion of threaded connector bolts which, in a manner presently to be described, are used to interconnect a second connector bracket  290  with bracket  274 . 
     Second connector bracket  290 , which functions to adjustably support rail ER- 2 , is adjustably interconnected with first connector bracket  274  in a manner now to be described. Like bracket  274 , leg  290   b  of connector bracket  290  is provided with first and second sets of through holes  292  and  294 . Holes  292  are disposed along a third line  296  that extends angularly with respect to first leg  290   a  of connector bracket  290  and also angularly with respect to line  286 . Similarly, through holes  294  are disposed along a fourth line  298  that extends angularly with respect to first leg  290   a  of connector bracket  290  and also angularly with respect to line  288 . Each of the through holes  292  and  294  are also generally rectangular in plan and are of a size and shape to closely receive the square shank portion of the threaded connector bolts. 
     Through holes  292  formed in bracket  290  are so constructed and arranged that a selected one of the through holes  292  can be moved into index with a selected one of the through holes  282  formed in bracket  274  by a sliding movement of bracket  290  relative to bracket  274 . Similarly, through holes  294  formed in bracket  290  are constructed and arranged so that a selected one of the through holes  294  can be moved into index with a selected one of the through holes  284  formed in bracket  274  when bracket  290  is moved from a first position to a second position relative to bracket  274 . More particularly, bracket  290  can be slidably moved relative to bracket  274  in a first direction generally parallel with leg  274   a  of bracket  274  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  274   a  of bracket  274 . 
     When second connector bracket  290  is correctly aligned with first connector bracket  274  and a selected one of the though holes  292  is indexably aligned with a selected one of the through holes  282 , a first bolt, such as a bolt  301 , can be introduced into the aligned through holes. Similarly, when the connector bracket  290  is correctly aligned with bracket  274  and a selected one of the through holes  294  is indexably aligned with a selected one of the through holes  284 , a second bolt, such as a bolt  303 , can be introduced into the aligned through holes. With the bolts  301  and  303  in position with the square shank portions  306  thereof (FIG. 13) closely received within the aligned holes, nuts such as nut  308  can be used to securely interconnect connector bracket  290  with bracket  274  in the manner shown in FIGS. 10,  11  and  12 . When the brackets are thusly connected, the square shaped shank portions  306  of the bolts will be snugly received within the indexably aligned through holes in the two brackets and will efficiently prevent sliding movement between the brackets. 
     Also forming a part of the connector apparatus of the form of the invention shown in FIGS. 1A and 12 are connector means for interconnecting the guide rail ER- 2  of the elevator system to leg  290   a  of second connector bracket  290 . In the present form of the invention, this connector means comprises a pair of spaced apart connector clips  310  that are connected to second leg  290   a  of connector bracket  290  by threaded bolts  312 . Each connector clip  310  has a rail engagement leg  310   a  that is adapted to clampingly engage the legs of the guide rail ER- 3  in the manner shown in FIG.  12 . 
     As shown in FIG. 12, connector assembly  252   a  of this latest form of the invention is of a similar construction to connector assembly  252  and comprises first and second spaced-apart right angle brackets  314  and  316 . Bracket  314  has a first generally planar, outwardly extending leg  318  that has an aperture  320  formed therein and a second perpendicularly extending second leg  322  that has an aperture  324  extending there through. Bracket  316  also has a first generally planar, outwardly extending leg  326  that has an aperture  328  formed therein and a second perpendicularly extending second leg  330  that has an aperture  332  extending there through. 
     Maintained in engagement with faces  250   b  of the vertically extending beams  250  by the interconnection means is the first leg  334   a  of an elongated, first connector bracket that is generally designated in the drawings by the numeral  334 . More particularly, leg  334   a  of bracket  334  has a first face  335  that engages the outer faces of the columns  250  and a second face  337  that engages the inner faces of legs  322  and  330 . Leg  334   a  of bracket  334  is also provided with an aperture  339  and a slot  341 , the purpose of which will presently be described. Interconnecting legs  318  and  326  of first and second angle brackets  316  and  314  is a tie bolt  338 . Tie bolt  338  extends through apertures  320  and  328  formed in legs  326  and  318  and is secured in position by a locking nut  339 . 
     As best seen in FIG. 12, first connector bracket  334  has a second leg  334   b  that extends generally perpendicularly to leg  334   a . Formed within second leg  334   b  of connector bracket  334  are first and second sets of through holes  342  and  344 , the purpose of which will presently be described. Holes  342  are disposed along a first line  346  that extends angularly with respect to first leg  334   a  of connector bracket  334 . Similarly, through holes  344  are disposed along a second line  348  that extends angularly with respect to first leg  334   a  of connector bracket  334 . Each of the through holes  342  and  344  are generally rectangular in plan and are of a size and shape to closely receive the square shank portion of threaded connector bolts which, in a manner presently to be described, are used to interconnect a second connector bracket  350  with bracket  334 . 
     Second connector bracket  350 , which functions to adjustably support rail ER- 2 , is adjustably interconnected with first connector bracket  334  in a manner now to be described. Like bracket  334 , leg  350   b  of connector bracket  350  is provided with first and second sets of through holes  352  and  354 . Holes  352  are disposed along a third line  356  that extends angularly with respect to first leg  350   a  of connector bracket  350  and also angularly with respect to line  346 . Similarly, through holes  354  are disposed along a fourth line  358  that extends angularly with respect to first leg  350   a  of connector bracket  350  and also angularly with respect to line  348 . Each of the through holes  352  and  354  are also generally rectangular in plan and are of a size and shape to closely receive the square shank portion of the threaded connector bolts. 
     Through holes  352  formed in bracket  350  are so constructed and arranged that a selected one of the through holes  352  can be moved into index with a selected one of the through holes  342  formed in bracket  334  by a sliding movement of bracket  350  relative to bracket  334 . Similarly, through holes  354  formed in bracket  350  are constructed and arranged so that a selected one of the through holes  344  formed in bracket  334  when bracket  350  is moved from a first position to a second position relative to bracket  334 . More particularly, bracket  350  can be slidably moved relative to bracket  334  in a first direction generally parallel with leg  334   a  of bracket  334  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  334   a  of bracket  334 . 
     When second connector bracket  350  is correctly aligned with first connector bracket  334  and a selected one of the through holes  352  is indexably aligned with a selected one of the through holes  342 , a first bolt, such as a bolt  361 , can be introduced into the aligned through holes. Similarly, when the connector bracket  350  is correctly aligned with bracket  334  and a selected one of the through holes  354  is indexably aligned with a selected one of the through holes  344 , a second bolt, such as a bolt  363 , can be introduced into the aligned through holes. With the bolts  361  and  363  in position with the square shank portions thereof closely received within the aligned holes, nuts such as nut  368  can be used to securely interconnect connector bracket  350  with bracket  334  in the manner shown in FIGS. 10,  11  and  12 . When the brackets are thusly connected, the square shaped shank portions of the bolts will be snugly received within the indexably aligned through holes in the two brackets and will efficiently prevent sliding movement between the brackets. Brackets  254 ,  256 ,  314  and  316 , along with tie bolts  373 ,  373   a ,  278 , and  338  comprise the interconnection means of this latest embodiment for maintaining brackets  274  and  334  in engagement with the structural components or beams  250 . 
     Also forming a part of the connector apparatus of the form of the invention shown in FIGS. 1A and 12 are connector means for interconnecting the guide rail ER- 1  of the elevator system to leg  350   a  of second connector bracket  350 . In the present form of the invention, this connector means comprises a pair of spaced apart connector clips  370  that are connected to second leg  350   a  of connector bracket  350  by threaded bolts  372 . Each connector clip  370  has a rail engagement leg  370   a  that is adapted to clampingly engage the legs of the guide rail ER- 2  in the manner shown in FIG.  12 . 
     As shown in FIG. 12, assemblies  252  and  252   a  are connected together by a pair of tie bolts  373  and  373   a . Tie bolt  373  extends through apertures  264  and  324  formed in brackets  254  and  314  respectively. Tie bolt  373   a  extends through apertures  272  and  332  of angle brackets  256  and  316 . Tie bolt  373  also extends through apertures  279  and  339  formed in legs  274   a  and  334   a  of brackets  274  and  334 . Tie bolt  373   a  also extends through slots  281  and  341  formed in legs  274   a  and  334   a  of brackets  274  and  334 . Because of the configuration of slots  281  and  341 , angle brackets  256  and  316  are free to move longitudinally of brackets  274  and  334  to accommodate for any misalignment of rails ER- 2  and ER- 3 . In this latest form of the invention, angle brackets  314  and  316 , along with tie bolts  373  and  373   a  comprise the beam interconnection means of the invention for interconnecting connector bracket  334  with beams  373  and  373   a.    
     Considering now the embodiment of the invention shown in FIGS. 14,  15 , and  16 . This embodiment is similar to the last described embodiment and comprises a connector apparatus for interconnecting the guide rails ER- 3  and ER- 4  of an elevator system with structural components shown here as a pair of spaced apart vertically extending beams  380  (not shown in FIGS.  1 A and  1 B). As best seen in FIG. 16, this connector apparatus comprises two substantially identical connector assemblies  382  and  382   a  that are interconnected by two substantially identical adjustment subassemblies  383 . In a manner presently to be described, the several cooperating assemblages just described function to interconnect the guide rails ER- 3  and ER- 4  of the elevator system with the pair of vertically extending beams  380 . 
     As shown in FIG. 16, each of the connector assemblies  382  and  382   a  of this latest form of the invention comprises a first connector bracket  384  and a second connector bracket  386  that is adjustably connected to first bracket  384 . In a manner presently to be described, adjustment assemblies  383 , which here comprise the interconnection means of this latest form of the invention, maintain the first leg  384   a  of each of the brackets  384  in pressural engagement with faces  380   a  of the horizontally extending beams  380 . 
     The second leg  384   b  of bracket  384 , which leg extends generally perpendicularly to leg  384   a  is provided with first and second sets of through holes  392  and  394 , the purpose of which will presently be described. Holes  392  are disposed along a first line  396  that extends angularly with respect to first leg  384   a  of connector bracket  384 . Similarly, through holes  394  are disposed along a second line  398  that extends angularly with respect to first leg  384   a  of connector bracket  384 . Each of the through holes  392  and  394  are generally rectangular in plan and are of a size and shape to closely receive the square shank portion of threaded connector bolts which, in a manner presently to be described, are used to interconnect a second connector bracket  386  with bracket  384 . 
     Second connector bracket  386 , which functions to adjustably support rail ER- 3 , is adjustably interconnected with first connector bracket  384  in a manner now to be described. Like bracket  384 , leg  386   a  of connector bracket  386  is provided with first and second sets of through holes  402  and  404 . Holes  402  are disposed along a third line  406  that extends angularly with respect to second leg  386   b  of connector bracket  386  and also angularly with respect to line  396 . Similarly, through holes  404  are disposed along a fourth line  408  that extends angularly with respect to leg  386   b  of connector bracket  386  and also angularly with respect to line  398 . Each of the through holes  402  and  404  of brackets  386  are also generally rectangular in plan and are of a size and shape to closely receive the square shank portion of the threaded connector bolts. 
     Through holes  402  formed in brackets  386  are so constructed and arranged that a selected one of the through holes  402  can be moved into index with a selected one of the through holes  392  formed in brackets  386  by a sliding movement of the brackets  386  relative to the brackets  384 . Similarly, through holes  404  formed in brackets  386  are constructed and arranged so that a selected one of the through holes  404  can be moved into index with a selected one of the through holes  394  formed in bracket  384  when brackets  386  are moved from a first position to a second position relative to bracket  384 . More particularly, brackets  386  can be slidably moved relative to brackets  384  in a first direction generally parallel with legs  384   a  of bracket  384  or, alternatively, can be slideably moved in a second direction generally perpendicular to legs  384   a  of bracket  384 . 
     As best seen by referring to FIG. 16, the interconnection means or adjustment assemblies  383  of this latest form of the invention comprise a generally U-shaped bracket  420  having a bight portion  420   a  and first and second spaced-apart legs  420   b . The connector assembly also includes a tie bolt  422 , the shank portion  422   a  of which is received within apertures  424  provided in legs  384   a  of brackets  384 . The shank portion of the tie bolt also extends through apertures provided in legs  420   b  of U-shaped member  420  in the manner shown in FIG. 16. A locking nut  426  secures bolt  422  in position and, when tightened, urges brackets  384  into pressural engagement with the faces of the spaced-apart beams or columns  380 . 
     Each of the U-shaped members  420  of the two identical adjustment assemblies  383  is provided with a pair of spaced-apart apertures  428  that receive jackbolts  430 . Jackbolts are threadably received within nuts  432  that bear on the outer surfaces of bight portion  420   a  of the U-shaped member  420 . Each of the jackbolts  430  terminates in an end  430   a  which is adapted to engage the outwardly facing walls of beams  380  in the manner shown in FIG.  16 . It is apparent that, with the construction shown, by first loosening nuts  426  and then by threadably adjusting jackbolts  430 , brackets  384  can be adjustably moved relative to columns  380  in the direction of the arrows  434  of FIG.  16 . Once in the desired position, nuts can be retightened and jackbolts  430  will function to securely position the assemblages  382  and  382   a  in engagement with beams  380 . 
     It is to be understood that when this latest embodiment of the apparatus of the invention is installed within the elevator hoistway, the various degrees of adjustment available to the installer permits the installer to precisely locate the guide rails ER- 3  and ER- 4  in an optimum position relative to the elevator cars with which they are associated. 
     Referring next the embodiment of the invention shown in area “F” of FIG. 1B, this embodiment, which is somewhat similar to the last two described embodiments, comprises a connector apparatus for interconnecting the guide rail R- 6  of an elevator system with a pair of spaced apart vertically extending columns  440 . As seen in FIGS. 16A and 16B, this embodiment includes a connector assembly  442  that is substantially identical to the connector assembly  252   a  as shown in FIG.  12 . This being the case, like numerals are used in FIGS. 16A and 16B to identify like components. 
     As best seen in FIG. 16B, connector assembly  442  of this latest form of the invention comprises first and second spaced-apart right angle brackets  314  and  316 . Bracket  314  has a first generally planar, outwardly extending leg  318  that has an aperture  320  formed therein and a second perpendicularly extending second leg  322  that has an aperture  324  extending there through. Bracket  316  also has a first generally planar, outwardly extending leg  326  that has an aperture  328  formed therein and a second perpendicularly extending second leg  330  that has a slot  443  extending there through. Disposed in engagement with faces  440   b  of the vertically extending beams  440  is the first leg  334   a  of an elongated, first connector bracket that is generally designated in the drawings by the numeral  334 . More particularly, leg  334   a  of bracket  334  has a first face  335  that engages the outer faces of the columns  440  and a second face  337  that engages the inner faces of legs  322  and  330 . Leg  334   a  of bracket  334  is also provided with an apertures  445  and  447 , the purpose of which will presently be described. Interconnecting legs  318  and  326  of first and second angle brackets  316  and  318  is a tie bolt  338 . Tie bolt  338  extends through apertures  320  and  328  formed in legs  316  and  318  and is secured in position by a locking nut  339 . 
     As shown in FIG. 16A, first connector bracket  334  has a second leg  334   b  that extends generally perpendicularly to leg  334   a . Formed within second leg  334   b  of connector bracket  334  are first and second sets of through holes  342  and  344 , the purpose of which will presently be described. Holes  342  are disposed along a first line  346  that extends angularly with respect to first leg  334   a  of connector bracket  334 . Similarly, through holes  344  are disposed along a second line  348  that extends angularly with respect to first leg  334   a  of connector bracket  334 . Each of the through holes  342  and  344  are generally rectangular in plan and are of a size and shape to closely receive the square shank portion of threaded connector bolts which, in a manner presently to be described, are used to interconnect a second connector bracket  350  with bracket  334 . 
     Second connector bracket  350 , which functions to adjustably support rail R- 6 , is adjustably interconnected with first connector bracket  334  in a manner now to be described. Like bracket  334 , leg  350   b  of connector bracket  350  is provided with first and second sets of through holes  352  and  354 . Holes  352  are disposed along a third line  356  that extends angularly with respect to first leg  350   a  of connector bracket  350  and also angularly with respect to line  346 . Similarly, through holes  354  are disposed along a fourth line  358  that extends angularly with respect to first leg  350   a  of connector bracket  350  and also angularly with respect to line  348 . Each of the through holes  352  and  354  are also generally rectangular in plan and are of a size and shape to closely receive the square shank portion of the threaded connector bolts. 
     Through holes  352  formed in bracket  354  are so constructed and arranged that a selected one of the through holes  352  can be moved into index with a selected one of the through holes  342  formed in bracket  334  by a sliding movement of bracket  350  relative to bracket  334 . Similarly, through holes  354  formed in bracket  350  are constructed and arranged so that a selected one of the through holes  354  can be moved into index with a selected one of the through holes  344  formed in bracket  334  when bracket  350  is moved from a first position to a second position relative to bracket  334 . More particularly, bracket  350  can be slidably moved relative to bracket  334  in a first direction generally parallel with leg  334   a  of bracket  334  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  334   a  of bracket  334 . 
     When second connector bracket  350  is correctly aligned with first connector bracket  334  and a selected one of the though holes  352  is indexably aligned with a selected one of the through holes  342 , a first bolt, such as a bolt  361 , can be introduced into the aligned through holes. Similarly, when the connector bracket  350  is correctly aligned with bracket  334  and a selected one of the through holes  354  is indexably aligned with a selected one of the through holes  344 , a second bolt, such as a bolt  363 , can be introduced into the aligned through holes. With the bolts  361  and  363  in position with the square shank portions thereof closely received within the aligned holes, nuts such as nut  368  can be used to securely interconnect connector bracket  350  with bracket  334  in the manner shown in the drawings. When the brackets are thusly connected, the square shaped shank portions of the bolts will be snugly received within the indexably aligned through holes in the two brackets and will efficiently prevent sliding movement between the brackets. 
     Also forming a part of the connector apparatus of this latest form of the invention shown in FIGS. 16A and 16B are connector means for interconnecting the guide rail ER- 6  of the elevator system to leg  350   a  of second connector bracket  350 . As before, this connector means comprises a pair of spaced apart connector clips  370  that are connected to second leg  350   a  of connector bracket  350  by threaded bolts  372 . Each connector clip  370  has a rail engagement leg  370   a  that is adapted to clampingly engage the legs of the guide rail ER- 6  in the manner shown in FIG.  16 B. 
     The connector apparatus of this latest form of the invention also includes third and fourth spaced-apart right angle brackets  446  and  448 . Bracket  446  has a first generally planar, outwardly extending leg  449  that has an aperture  450  formed therein and a second perpendicularly extending second leg  452  that has an aperture  454  extending there through. Bracket  448  also has a first generally planar, outwardly extending leg  456  that has an aperture  458  formed therein and a second perpendicularly extending second leg  460  that has a slot  462  extending there through. 
     Disposed in engagement with faces  440   c  of the vertically extending beams  440  is the first leg  464   a  of an elongated, connector bracket that is generally designated in the drawings by the numeral  464 . More particularly, leg  464   a  of bracket  464  has a first face  467  that engages the outer faces of the columns  440  and a second face  469  that engages the inner faces of legs  452  and  460  of brackets  446  and  448 . Interconnecting legs  449  and  456  of second and third angle brackets  446  and  448  is a tie bolt  470 . Tie bolt  470  extends through apertures  450  and  458  formed in legs  449  and  456  and is secured in position by a locking nut  471 . 
     As shown in FIG. 16B, the assemblage made up of angle brackets  446 ,  448  and  464  and tie bolt  470  are interconnected with assembly  442  by a pair of tie bolts  475  and  477 . Tie bolt  475  extends through apertures  454  and  324  formed in brackets  464  and  314  respectively. Tie bolt  477  extends through slots  462  and  443  of angle brackets  448  and  316  respectively. Tie bolt  475  also extends through apertures  455  and  445  formed in legs  464   a  and  334   a  of brackets  464  and  334 . Tie bolt  477  also extends through slots  462  and  443  formed in legs  460  and  330  of brackets  448  and  316  respectively. Because of the configuration of slots  462  and  443 , assembly  442  is free to move longitudinally of columns  440  to accommodate for any misalignment of rail ER- 6 . In this latest form of the invention, angle brackets  316 ,  318 ,  448  and  446 , along with tie bolts  475  and  477  comprise the beam interconnection means of the invention for interconnecting connector bracket  334  with beams  440 . 
     Turning next to FIGS. 17,  18  and  19 , these drawings more fully illustrate the form of the connector apparatus of the invention shown in portion E of FIG.  1 B. This apparatus, which is generally designated by the numeral  480 , functions to interconnect rails R- 4  and R- 5  with a horizontally extending beam  482 . The apparatus here comprises a bracket in the form of a generally “U”-shaped member  484  (FIG. 18) and first, second, third and fourth angle brackets  485 ,  486 ,  488  and  490  that are connected to the bight portion  492  thereof (FIG.  19 ). In addition to the generally planar bight portion  492 , member  484  has first and second upstanding legs or side portions  494  and  496  that extend generally perpendicular to bight portion  492 . 
     As best seen in FIG. 17, spaced-apart brackets  485  and  486  are connected by a tie bolt  500 , while spaced-apart brackets  488  and  490  are connected by a tie bolt  502 . Disposed closely adjacent to one side of beam  482  and interconnecting first and third brackets  485  and  488  with a pair of capture plates  506  (FIG. 19) are spaced-apart tie bolts  508  and  510  respectively. In similar fashion, tie bolts  512  and  514 , that are also disposed closely adjacent the opposite side of beam  482 , function to interconnect second and fourth angle brackets  486  and  490  with spaced-apart capture plates  506 . 
     As shown in FIG. 17, the underside of U shaped member  484  and the upper sides capture plates  506  are held in secure engagement with beam  482  by the four tie bolts  508 ,  510 ,  512 , and  514 . As is also shown in FIG. 17, slots  517  formed in angle brackets  484  permit transverse movement of the U-shaped member  484  relative to beam  482 . In this latest form of the invention, angle brackets  485 ,  486 ,  488  and  490 , along with capture plates  506  and tie bolts  500 ,  502 ,  508 ,  510 ,  512  and  514  comprise the beam interconnection means of the invention for interconnecting connector bracket  484  with beam  482 . 
     Also forming a part of the connector apparatus of this latest form of the invention are connector means for interconnecting guide rails R- 4  and R- 5  of the elevator system to legs  494  and  496  of U shaped member  484 . This connector means here comprises a pair of spaced apart connector clips  520  that are connected to first leg  494  of U shaped member  484  by bolts  521  and a pair of spaced apart connector clips  522  that are connected to the second leg  496  of U shaped member  484  by bolts  523 . As best seen in FIG. 17, each of the connector clips has a rail engagement leg  526  that is adapted to clampingly engage the legs of the guide rails in the manner shown in FIG.  17 . 
     Referring next to FIGS. 20,  21  and  22  another form of the connector apparatus of the invention is there shown and generally designated by the numeral  530 . This apparatus, which functions to interconnect rails R- 6  and R- 7  with a horizontally extending “I” beam  532 , comprises an upper U-shaped member  533 , a pair of generally U-shaped members  534  and  536  that are connected to U-shaped member  533  and four pair of jackbolts  530  that are interconnected with the bight portions  535  of the U-shaped members  534  and  536 . As best seen in FIG. 20, U-shaped member  534  is disposed on one side of the I beam while U-shaped members  536  is disposed on the opposite side of the I beam. 
     As shown in FIGS. 20 and 22, each of the legs of the U-shaped bracket  534  is provided with a pair of longitudinally spaced apertures  541  that receive a pair of tie bolts  544 . Similarly, each of the legs of U-shaped brackets  536  is provided with a pair of longitudinally spaced apertures  543  that receive a pair of tie bolts  546 . Tie bolts  544  extend through a pair of spaced apart apertures  547  provided in U-shaped member  533 , through apertures  541  provided in the legs of U-shaped member  534  and through apertures  549 . provided in a pair of capture plates  550  (FIG.  22 ). Similarly, tie bolts  546  extend through a pair of spaced apart apertures  553  provided in this U-shaped member  533 , through apertures  543  provided in the legs of U-shaped member  536  and through apertures  555  provided in capture plates  550  (FIGS.  21  and  22 ). With the construction thus described and as illustrated in the drawings, tie bolts  544  and  546 , which comprise the connector means of the invention, function to maintain U-shaped member  533  in engagement with the top surface of the “I” beam, function to maintain capture plates  550  in engagement with the bottom surface of the I beam and function to maintain U-shaped members  534  and  536  at locations intermediate U-shaped member  533  and capture plates  550 . 
     Jackbolts  530  are threadably received within adjustment nuts  530   a  that are connected to each of the jackbolts. Adjustment nuts  530   a  bear upon the outer surfaces of the bight portions of U-shaped members  534  and  536  so that, when the jackbolts are threaded inwardly and outwardly with respect to nuts  530   a , the extremities by  530   b  of the jackbolts can be moved into and out of pressural engagement with the central web of the “I” beam, thereby permitting adjustment of the assemblage relative to rails R- 6  and R- 7  as indicated by the arrows  557  in FIG.  20 . In this latest form of the invention, U shaped members  534  and  536 , along with jackbolts  530  and tie bolts  544  and  546  comprise the beam interconnection means of the invention for interconnecting connector bracket  533  with I beam  532 . 
     Also forming a part of the connector apparatus of this latest form of the invention are connector means for interconnecting guide rails R- 6  and R 7  of the elevator system to legs  533   a  of U shaped member  533 . This connector means here comprises a pair of spaced apart connector clips  560  that are connected to each of the legs  533   a  of U shaped member  533  by bolts  562 . As best seen in FIG. 22, each of the connector clips has a rail engagement leg  560   a  that is adapted to clampingly engage the legs of the guide rails in the manner shown in FIG.  22 . 
     Considering now the embodiment of the invention shown in FIGS. 23,  24  and  25 , this embodiment is similar in many respects to that shown in FIGS. 14,  15  and  16  and like numbers are used to identify like components. This latest embodiment comprises a connector apparatus for interconnecting the guide rails R- 8  and R- 9  of an elevator system with a horizontally extending beam  570  that is generally rectangular in cross section. As best seen in FIG. 25, this connector apparatus comprises two identical connector assemblies  572  and  572   a  that are interconnected by a pair of tie bolts  573  (FIG.  25 ). 
     As shown in FIG. 25, each of the connector assemblies  572  and  572   a  of this latest form of the invention comprises a first connector bracket  574  and a second connector bracket  386  that is adjustably connected to first bracket  574  and is substantially identical to connector bracket  386  of FIG.  16 . Second leg  574   b  of each bracket  574 , which leg extends generally perpendicularly to leg  574   a  and accepts tie bolts  573 , is provided with first and second sets of through holes  576  and  578 , the purpose of which will presently be described. Holes  576  are disposed along the line  580  that extends angularly with respect to first leg  574   a  of connector bracket  574 . Similarly, through holes  578  are disposed along a line  580  that extends angularly with respect to first leg  574   a  of connector bracket  574 . Each of the through holes  576  and  578  are generally rectangular in plan and are of a size and shape to closely receive the square shank portion of threaded connector bolts which, in a manner presently to be described, are used to interconnect a second connector bracket  386  with bracket  574 . 
     Second connector brackets  386 , which function to adjustably support rails R- 8  and R- 9 , are adjustably interconnected with first connector brackets  574  in a manner now to be described. As before, leg  386   a  of each connector bracket  386  is provided with first and second sets of through holes  402  and  404 . Holes  402  are disposed along the line  406  that extends angularly with respect to second leg  386   b  of connector bracket  386  and also angularly with respect to line  580 . Similarly, through holes  404  are disposed along a line  408  that extends angularly with respect to leg  386   b  of connector bracket  386  and also angularly with respect to line  580 . Each of the through holes  402  and  404  of brackets  382  and  382   a  are also generally rectangular in plan and are of a size and shape to closely receive the square shank portion of the threaded connector bolts. 
     Through holes  402  formed in brackets  386  are so constructed and arranged that a selected one of the through holes  402  can be moved into index with a selected one of the through holes  576  formed in brackets  574  by a sliding movement of the brackets  386  relative to the brackets  574 . Similarly, through holes  404  formed in brackets  386  are constructed and arranged so that a selected one of the through holes  404  can be moved into index with a selected one of the through holes  578  formed in brackets  574  when brackets  386  are moved from a first position to a second position relative to brackets  574 . More particularly, brackets  386  can be slidably moved relative to brackets  574  in a first direction generally parallel with legs  574   a  of brackets  574  or, alternatively, can be slidably moved in a second direction generally perpendicular to legs  574   a  of brackets  574 . In this latest form of the invention, capture plates  585 , along with tie bolts  587  and  573  comprise the beam interconnection means of the invention for interconnecting connector brackets  574  with beam  570 . 
     Also forming a part of the connector apparatus of this latest form of the invention are connector means for interconnecting guide rails R- 8  and R- 9  of the elevator system to legs  386   b  of brackets  386 . This connector means here comprises a pair of spaced apart connector clips  370  that are connected to each of the legs  386   b  by bolts  372 . As best seen in FIG. 25, each of the connector clips has rail engagement legs  370   a  that are adapted to clampingly engage the legs of the guide rails in the manner shown in FIG.  25 . As best seen in FIG. 24, brackets  574  are connected to a pair of capture plates  585  that extend beneath beam  570  by four spaced apart tie bolts  587  that are disposed closely adjacent to the sides of beam  570 . As indicated in FIG. 24, the undersides of brackets  574  and the upper sides of capture plates  585  are held in secure engagement with beam  482  by the four tie bolts. As previously mentioned, assemblages  572  and  572   a  are connected together in the manner best seen in FIGS. 23 and 25 by tie bolts  573 . 
     It is to be understood that when the apparatus of this latest form of the invention is appropriately installed within the elevator hoistway, the various degrees of adjustment available to the installer permit the installer to precisely locate the guide rails R- 8  and R- 9  in an optimum position relative to the involved elevator cars. 
     Considering now the embodiment of the invention shown in FIGS. 26 and 27, this embodiment is similar in many respects to that shown in FIGS. 8 and 9 and like numbers are used to identify like components. This latest embodiment comprises a connector apparatus for interconnecting the guide rail R- 10  of an elevator system with a wall W- 5  of the building structure that houses the elevator system. As best seen in FIG. 27, the connector assembly  590  of this latest form of the invention comprises a first connector bracket  160  that is substantially identical to bracket  160  of FIG.  9  and includes a first generally planar first leg  162  that is adjustably connected to the supporting structure W- 5  in the manner described in connection with the embodiment of FIG.  9 . 
     Second leg  164  of bracket  160  is provided with a first set of through holes  186  and a spaced apart second set of first through holes  190 . Adjustably interconnected with first connector bracket  160  is a second connector bracket  594 . Second bracket  594  has a first leg  596  and a second leg  598  that extends generally perpendicular to first leg  596 . Second bracket  594  is also provided with a first set of through holes  600  that are disposed along a first line  601  that extends at an angle with respect to first leg  596 . Similarly, leg  598  is provided with another set of through holes  602  that are disposed along a line  604  that extends at an angle with respect to first leg  596 . As in the embodiment of FIG. 9, through holes  600  formed in bracket  594  are so constructed and arranged that a selected one of the through holes  600  can be moved into index with a selected one of the through holes  186  formed in bracket  160  by a sliding movement of bracket  594  relative to bracket  160 . Similarly, through holes  602  formed in bracket  594  are constructed and arranged so that a selected one of the through holes  602  can be moved into index with a selected one of the through holes  190  formed in bracket  160  when bracket  594  is slidably moved from a first position to a second position relative to bracket  160 . More particularly, bracket  594  can be slidably moved relative to bracket  160  in a first direction generally parallel with leg  162  of bracket  160  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  162  of bracket  160 . 
     When second connector bracket  594  is correctly aligned with first connector bracket  160  and when the selected though holes in the brackets are indexably aligned, the brackets can be interconnected using bolts  217  and  219  in the manner described in connection with the embodiment of FIG.  9 . 
     As in the earlier described embodiment, the connector apparatus of this latest form of the invention includes connector means for connecting the guide rail R- 10  of the elevator system to first leg  596  of second bracket  594  in the manner illustrated in FIGS. 26 and 27. In this latest form of the invention, the connector means is somewhat different from that shown in FIGS. 8 and 9, but again comprises first and second spaced-apart connector clips  228  that are adjustably connected to first leg of connector bracket  594  by threaded bolts  229 . As before, each connector clip  228  has a rail engagement leg  228   a  that is adapted to clampingly engage the legs of the guide rail R- 10 . 
     Bolts  229  extend through slots  607  provided in leg  596  of bracket  594  and also extend through apertures  611  provided in a pair of angle brackets  610  that are connected to bracket  594  by the bolts  229  and nuts  229   a  in the manner best seen in FIG.  27 . Brackets  610  include an outwardly extending leg  614  that is provided with an aperture  615  that accept threaded jackbolts  618 . Bracket  594  has a central upstanding wall  620  that is engaged by the ends  618   a  of each of the jackbolts  618 . With this construction, it is apparent that by threading the jackbolts inwardly and outwardly relative to wall  620 , the position of angle brackets  610  along with clips  228  can be moved to further accommodate any misalignment of rail R- 10 . 
     Turning finally to FIGS. 28 and 29, the embodiment there shown is similar in many respects to that shown in FIGS. 2,  3  and  4  and like numbers are used to identify like components. The basic difference between this latest embodiment and that shown in FIGS. 2,  3  and  4  resides in the provision of a slightly different rail connector means for supporting rail R- 11 . This latest embodiment comprises a connector assembly  15  that function to interconnect guide rail R- 11  with two pair of vertically extending beams generally designated in the drawings by the numerals  625  and  625   a.    
     As shown in FIG. 29, connector assembly  15  of this form of the invention, like that shown in FIG. 2, comprises first, second, third, and fourth spaced-apart right angle brackets  16 ,  18 ,  20 , and  22  respectively that function to interconnect a bracket  628  with columns  625  and  625   a  in the manner described in connection with the connection of bracket  66  to the columns in the embodiment of FIG.  2 . Bracket  628  is identical to bracket  66  save that bracket  628  does not have end walls  76 , but does have a central, outwardly extending wall  630  that is connected to leg  628   a  of bracket  628 . The purpose of this central wall will presently be described. 
     As best seen in FIG. 29, connector bracket  42  of this latest embodiment has a second leg  42   b  that extends generally perpendicularly to leg  42   a . Formed within second leg  42   b  of connector bracket  42  are first and second sets of through holes  59  and  61  that are adapted to index with first and second sets of through holes  633  and  635  formed in leg  628   b  of bracket  628 . More particularly, as in the embodiment of FIG. 2, through holes  633  formed in bracket  628  are so constructed and arranged that a selected one of the through holes  633  can be moved into index with a selected one of the through holes  59  formed in bracket  42  by a sliding movement of bracket  42  relative to bracket  628 . Similarly, through holes  635  formed in bracket  628  are constructed and arranged so that a selected one of the through holes  635  can be moved into index with a selected one of the through holes  61  formed in bracket  42  when bracket  628  is slidably moved from a first position to a second position relative to bracket  42 . More particularly, bracket  628  can be slidably moved relative to bracket  42  in a first direction generally parallel with leg  42   a  of bracket  42  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  42   a  of bracket  42 . When second connector bracket  628  is correctly aligned with first connector bracket  42  and when the selected though holes in the brackets are indexably aligned, the brackets can be interconnected using bolts  72  and  74  in the manner described in connection with the embodiment of FIG.  2 . In this latest form of the invention, angle brackets  16 ,  18 ,  20  and  22 , along with spanner plate  32 , comprise the interconnection means of the invention for interconnecting first connector bracket  42  with beams  625  and  625   a.    
     Also forming a part of the connector apparatus of the form of the invention shown in FIGS. 28 and 29 are connector means for interconnecting guide rail R- 11  to leg  628   a  of second connector bracket  628 . In this latest form of the invention, this connector means comprises a pair of spaced apart connector clips  638  that are adjustably connected to leg  628   a  of connector bracket  628  by threaded bolts  75 . Each connector clip  638  has a rail engagement leg  638   a  that is adapted to clampingly engage the legs of the guide rail R- 11 . 
     Bolts  75  extend through slots  639  provided in leg  628   a  of bracket  628  and also extend through apertures  641  provided in a pair of angle brackets  644  that are connected to bracket  628  by the bolts  75  and nuts  80  in the manner best seen in FIG.  29 . Brackets  644  include an outwardly extending leg  644   a , each if which is provided with an aperture  645  that accepts a threaded jackbolt  648 . The ends  648   a  of each of the jackbolts engage earlier identified central wall  630  so that by threading the jackbolts inwardly and outwardly relative to wall  630 , the position of angle brackets  644  along with clips  638  can be adjusted to further accommodate any misalignment of rail R- 11 . 
     As in the earlier described embodiments, when the apparatus of this latest form of the invention is appropriately installed within the elevator hoist the various degrees of adjustment available to the installer permit the installer to precisely locate guide rail R- 11  in an optimum position relative to the involved elevator cars. 
     Considering now the embodiment of the invention shown in FIGS. 30,  31 ,  32  and  33 , this embodiment is similar in some respects to that shown in FIGS. 17,  18  and  19 . This latest embodiment comprises a connector apparatus for interconnecting the guide rails R- 12  and R- 13  of an elevator system with a horizontally extending beam  660  that is generally rectangular in cross section. As best seen in FIG. 32, this connector apparatus comprises a generally “U” shaped member  662  (FIG. 33) and four angle brackets  664 ,  666 ,  668  and  670  that are connected to the bight portion  662   a  thereof (FIG.  32 ). In addition to bight portion  662   a , member  662  has two upstanding side portions  662   b  and  662   c.    
     As best seen in FIG. 32, brackets  664  and  666  are connected by a tie bolt  672 , while brackets  668  and  670  are connected by a tie bolt  674 . Disposed closely adjacent to one side of beam  660  and interconnecting first and third brackets  664  and  668  with a pair of capture plates  678  (FIG. 32) are spaced-apart tie bolts  680  and  682  respectively. In similar fashion, tie bolts  684  and  686 , that are also disposed closely adjacent the opposite side of beam  660 , function to interconnect second and fourth angle brackets  666  and  670  with capture plates  678 . 
     As shown in FIG. 30, the underside of U-shaped member  662  and the upper sides capture plates  678  are held in secure engagement with beam  660  by the four tie bolts  680 ,  682 ,  684  and  686 . As is also shown in FIG. 32, slots  689  formed in angle brackets  662  permit transverse movement of the U-shaped member  662  relative to beam  660 . In this latest form of the invention, angle brackets  664 ,  666 ,  668  and  670 , along with capture plates  678  and tie bolts  680 ,  682 ,  684 , and  686 , comprise the beam interconnection means of the invention for interconnecting connector bracket  662  with beam  660 . 
     Also forming a part of the connector apparatus of this latest form of the invention are connector means for interconnecting guide rails R- 12  and R- 13  of the elevator system to legs  662   b  and  662   c  of U-shaped member  662 . This connector means here comprises a pair of spaced apart connector slips  692  and  694  that are connected to first leg  662   b  of U-shaped member  662  by bolts  695  and a pair of spaced-apart connector clips  696  and  698  that are connected to the second leg  662   c  of U-shaped member  662  by bolts  699 . As best seen in FIG. 32, each of the connector clips has a rail engagement leg  700  that is adapted to clampingly engage the legs of the guide rails in the manner shown in FIG.  32 . 
     As best seen in FIG. 33, sidewall  662   b  of U-shaped member  662  is provided with spaced-apart, elongated-bolt-receiving apertures  702  that are adapted to receive connector bolt  695 . Similarly, sidewall  662   c  of the U-shaped member is provided with elongated-bolt-receiving apertures  704  for receiving connector bolts  669 . Connector bolts  695  also extend through bores provided in one leg of a pair of angle brackets  706  and  708  and along with nuts  709  function to interconnect brackets  706  and  708  with sidewall  662   b . In like manner connector bolts  699  also extend through bores provided in one leg of a pair of angle brackets  710  and  712  and along with nuts  711  function to interconnect brackets  710  and  712  with sidewall  662   c  of U-shaped member  662 . 
     A novel feature of this latest form of the invention comprises adjustment means for adjusting the position of the connector chips relative to member  662 . This adjustment means here comprises a jackbolt supporting bracket  716  that is connected to sidewall  662   b  of U-shaped member  662  by a bolt  714  is a jackbolt supporting bracket  716 . Similarly, a jackbolt supporting bracket  718  is connected to sidewall  662   c  by a bolt  720 . Leg  716   a  of bracket  716  is provided with a threaded bore  716   c  that is adapted to receive the shank of a threaded jackbolt  722 . Angle brackets  706  and  708  are also aperture to receive the shank of jackbolt  722  in the manner shown in FIG.  32 . As shown in FIG. 32, jackbolt  722  is threadably received within a series of adjustment nuts  724  that bear upon the surfaces of the outwardly extending legs of brackets  716 ,  706  and  708  so that, when the jackbolt is threaded inwardly and outwardly with respect to nuts  724 , clips  692  and  694  can be adjusted longitudinally of side  662   b  to adjustably position rail R- 12 . It is apparent that by loosening adjustment nuts  724 , bolts  695  along with clips  692  and  694  can be moved toward and away from guide rail R- 12  and can be securely locked in position by retightening the locking nuts. 
     As is shown in FIG. 32, leg  718   a  of bracket  718  is provided with a threaded bore  718   c  that is adapted to receive the shank of a threaded jackbolt  726 . Angle brackets  710  and  712  are also aperture to receive the shank of jackbolt  726  in the manner there illustrated. Jackbolt  726  is threadably received within a series of adjustment nuts  728  that bear upon the surfaces of the outwardly extending legs of brackets  718 ,  710  and  712  so that, when the jackbolt is threaded inwardly and outwardly with respect to nuts  728 , clips  696  and  698  can be adjusted longitudinally of side  662   c  to adjustably position rail R- 13 . It is apparent that by loosening adjustment nuts  728 , bolts  699  along with clips  696  and  698  can be moved toward and away from guide rail R- 13  and can be securely locked in position by retightening the locking nuts. 
     It is to be understood that when the apparatus of the invention is installed within the hoistway in the manner shown in FIG. 1A, the various degrees of adjustment available to the installer permits the installer to precisely locate the guide rails R- 12  and R- 13  in an optimum position to permit smooth and efficient operation of the elevator system. 
     Turning next to FIGS. 34,  35 ,  36  and  37 , still another embodiment of the invention is there shown. This embodiment, which is similar in some respects to that shown in FIGS. 28 and 29, comprises a connector apparatus for interconnecting a guide rail R- 14  of an elevator system with a horizontally extending beam  740  that is generally rectangular in cross section. As best seen in FIGS. 35 and 36, this connector apparatus comprises a generally rectangularly shaped member  742  (FIG. 36) and four angle brackets  744 ,  746 ,  748  and  750  that are connected thereto. 
     As shown in FIG. 34, brackets  744  and  746  are connected by a tie bolt  752 , while brackets  748  and  750  are connected by a tie bolt  754 . Disposed closely adjacent to one side of beam  740  and interconnecting first and third brackets  744  and  748  with a pair of angle brackets  756  (FIG. 36) are spaced-apart tie bolts  758  and  760  respectively. In similar fashion, tie bolts  762  and  764 , that are also disposed closely adjacent the opposite side of beam  740 , function to interconnect second and fourth angle brackets  746  and  750  with angle brackets  766 . Brackets  756  and  766  are connected by a tie bolt  770 , while brackets  748  and  750  are connected by a tie bolt  754 . 
     As illustrated in FIG. 34, the underside of member  742  and the upper sides of angle brackets  756  and  766  are held in secure engagement with beam  740  by the four tie bolts  758 ,  760 ,  762  and  764 . Slots formed in the lower angle brackets permit transverse movement of member  742  relative to beam  740 . In this latest form of the invention, the upper and lower angle brackets, along with tie bolts  758 ,  760 ,  762  and  764 , comprise the beam interconnection means of the invention for interconnecting connector member  742  with beam  740 . 
     A connector bracket  774  of the configuration shown in FIG. 37 is adjustably connected to connector member  742  by a pair of connector bolts  775  and  777 . As best seen in FIG. 36, connector bracket  774  is provided with first and second sets of through holes  776  and  778 , the purpose of which will presently be described. Holes  776  are disposed along a line  780  that extends angularly with respect to a connector leg  774   a  formed on connector bracket  774 . Similarly, through holes  778  are disposed along a line  782  that extends angularly with respect to connector leg  774   a  of connector bracket  774 . Each of the through holes  776  and  778  are generally rectangular in plan and are of a size and shape to closely receive the square shank portion of the threaded connector bolts  775  and  777  which, are used to interconnect connector bracket  774  with member  742 . 
     Connector bracket  774 , which function to adjustably support rail R- 14  is adjustably interconnected with member  742  in a manner now to be described. As shown in FIG. 36 member  742  is provided with first and second sets of through holes  784  and  786 . Holes  784  are disposed along a line  788  that extends angularly with respect to the plane of leg  774   a  of connector bracket  774  and also angularly with respect to line  780 . Similarly, through holes  786  are disposed along a line  790  that extends angularly with respect to the plane of leg  774   a  of connector bracket  774  and also angularly with respect to line  782 . Each of the through holes  784  and  786  of member  742  are also generally rectangular in plan and are of a size and shape to closely receive the square shank portion of the threaded connector bolts  775  and  777 . 
     In the manner shown in FIG. 36, through holes  776  are adapted to index with through holes  784  and, through holes  778  are adapted to index with through holes  786 . More particularly, as in the earlier described embodiments 2, through holes  776  formed in bracket  774  are so constructed and arranged that a selected one of the through holes  776  can be moved into index with a selected one of the through holes  784  formed in member  742  by a sliding movement of bracket  774  relative to member  742 . Similarly, through holes  778  formed in bracket  774  are constructed and arranged so that a selected one of the through holes  778  can be moved into index with a selected one of the through holes  786  formed in member  742  when bracket  774  is slidably moved from a first position to a second position relative to member  742 . More particularly, bracket  774  can be slidably moved relative to member  742  in a first direction generally parallel with leg  774   a  of bracket  774  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  774   a  of bracket  774 . When connector bracket  774  is correctly aligned with member  742  and when the selected though holes in the components are indexably aligned, the components can be interconnected using bolts  775  and  777  in the manner previously described herein. 
     Also forming a part of the connector apparatus of the form of the invention shown in FIGS. 34,  35 ,  36  and  37  are connector means for interconnecting guide rail R- 14  to leg  774   a  of connector bracket  774 . In this latest form of the invention, this connector means comprises a pair of spaced apart connector clips  794  that are adjustably connected to leg  774   a  of connector bracket  774  by threaded bolts  796 . Each connector clip  794  has a rail engagement leg  794   a  that is adapted to clampingly engage the legs of the guide rail R- 14 . 
     Bolts  796  extend through slots  797  provided in leg  774   a  of bracket  774  and also extend through apertures  799  provided in a pair of angle brackets  800  that are connected to bracket  774  by the bolts  796  and nuts  802  in the manner best seen in FIG.  36 . Brackets  800  include an outwardly extending leg  800   a , each if which is provided with an aperture  805  that accepts a threaded jackbolt  806 . 
     Also connected to leg  774   a  of bracket  774  by a bolt  808  is a jackbolt supporting bracket  810 . Leg  810   a  of bracket  810  is provided with a bore  810   b  that is adapted to receive the shank of a threaded jackbolt  806 . As shown in FIG. 36, jackbolt  806  is threadably received within a series of adjustment nuts  812  that bear upon the surfaces of the outwardly extending legs of brackets  805  and  810 , so that, when the jackbolt is threaded inwardly and outwardly with respect to nuts  812 , clips  794  can be adjusted longitudinally of leg  774   a  to adjustably position rail R- 14 . It is apparent that by loosening adjustment nuts  812 , bolts  796  along with clips  794  can be moved toward and away from guide rail R- 14  and can be securely locked in position by retightening the locking nuts. 
     As in the earlier described embodiments, when the apparatus of this latest form of the invention is appropriately installed within the elevator hoist the various degrees of adjustment available to the installer permit the installer to precisely locate guide rail R- 14  in an optimum position relative to the involved elevator cars. 
     Turning next to FIGS. 38,  39 ,  40  and  41  another form of connector apparatus for interconnecting the guide rails of an elevator system with a pair of vertically extending columns is there shown. Referring particularly to FIGS. 39 and 41, the connector assembly of this form of the invention can be seen to comprise a main support structure  820  (FIG. 41) to which first, second, third, and fourth spaced-apart right angle brackets  822 ,  824 ,  826  and  828  are connected (FIG.  39 ). As best seen in FIG. 41, main support structure  820  comprises a base  830  having a pair of spaced-apart elongated sidewalls  832  and  834  respectively and a central, generally planer portion  836 . Each of the sidewalls has a circular aperture  838  and elongated aperture  840 . Also comprising of main support structure  820  is a generally U- shaped connector member  844  that includes a bight portion  820   a  and a pair of upstanding leg portions  820   b  and  820   c  respectively. Connected to each of the leg portions proximate their center is an inwardly extending apertured connector wall  846  the purpose of which will presently be described. Angle bracket  822  has a first generally planar, outwardly extending leg  822   a  that has an aperture  823  formed therein and a second perpendicularly extending second leg  822   b  that has an aperture  825  extending there through. Similarly, angle bracket  824  has a first generally planar, outwardly extending leg  824   a  that has an aperture  825   a  formed therein and a second perpendicularly extending second leg  824   b  that has an aperture  827  extending there through. In like manner, angle bracket  826  has a first generally planar, outwardly extending leg  826   a  that has an aperture  829  formed therein and a second perpendicularly extending second leg  826   b  that has an aperture  831  extending there through. Similarly, angle bracket  828  has a first generally planar, outwardly extending leg  828   a  that has an aperture  833  formed therein and a second perpendicularly extending second leg  828   b  that has an aperture  835  extending there through. 
     A tie bolt  850  extends through apertures  825 ,  840  and  827  and functions to interconnect angle brackets  822  and  824  and to secure them in engagement with vertical column  854 . Similarly, a tie bolt  852  extends through apertures  831 ,  838  and  835  and functions to interconnect angle brackets  826  and  828  and to secure them in engagement with vertical column  856  (FIG.  39 ). 
     As is also illustrated in FIG. 39, an elongated, threaded tie bolt  858  extends through apertures  823  and  829  and functions to interconnect angle brackets  822  and  826 . Similarly, an elongated tie bolt  860  extends through apertures  825   a  and  833  and functions to interconnect angle brackets  824  and  828 . Tie bolts also function to bring tie bolts  850  and  852  into engagement with the vertical columns in the manner shown in FIG.  39 . With the construction thus described main support structure  820  can be securely interconnected with vertical columns  854  and  856  at any desired location along the columns. 
     Formed within bight portion  820   a  of connector  820  are first and second sets of through holes  864  and  866 , the purpose of which will presently be described. Holes  864  are disposed along the line  868  that extends at an acute angle with respect to legs  820   b  and  820   c  of connector  820 . Similarly, through holes  866  are disposed along a line  870  that extends at an acute angle with respect to legs  820   b  and  820   c  of connector  820 . Each of the through holes  864  and  866  are generally rectangular in plan and are of a size and shape to closely receive the square shank portion of threaded connector bolts which, in a manner presently to be described, are used to interconnect member  820  with central, generally planer portion  836  of base  830  of main support structure  820 . 
     Like bight portion  820   a , portion  836  is provided with first and second sets of through holes  874  and  876  (FIG.  39 ). Holes  874  are disposed along the line  880  that extends at an acute angle with respect to sides  820   b  and  820   c . Similarly, through holes  876  are disposed along a line  882  that extends angularly with respect to sides  820   b  and  820   c . Each of the through holes  874  and  876  are also generally rectangular in plan and are of a size and shape to closely receive the square shank portion of threaded connector bolts  888 . 
     Through holes  864  formed in bracket  820  are so constructed and arranged that a selected one of the through holes can be moved into index with a selected one of the through holes  874  formed in base portion  836  by a sliding movement of bracket  820  relative to base portion  836 . Similarly, through holes  866  formed in bracket  820  are constructed and arranged so that a selected one of the through holes can be moved into index with a selected one of the through holes  876  formed in base portion  836  when bracket  820  is moved from a first position to a second position relative to the base portion. More particularly, bracket  820  can be slidably moved relative to the base portion in a first transverse direction generally parallel with sides  820   b  and  820   c  of bracket  820  or, alternatively, can be slidably moved in a second direction generally perpendicular to sides  820   b  and  820   c  of bracket  820 . 
     When connector bracket  820  is correctly aligned with base portion  836  and a selected one of the though holes  864  is indexably aligned with a selected one of the through holes  874 , a selected connector bolt  888  can be introduced into the aligned through holes. Similarly, when the connector bracket  820  is correctly aligned with base portion  836  and a selected one of the though holes  866  is indexably aligned with a selected one of the through holes  876 , a selected connector bolt  888  can be introduced into the aligned through holes. With the bolts in position with the square shank portions thereof closely received within the aligned holes, nuts such as nut  888   a  can be used to securely interconnect connector bracket  820  with base portion  836  in the manner shown in FIG.  38 . When the components are thusly connected, the square shaped shank portions of the bolts will be snugly received within the indexably aligned through holes and will efficiently prevent sliding movement between the components even under severe loading conditions. 
     Also forming a part of the connector apparatus of the form of the invention shown in FIGS. 38 and 39 are connector means for adjustably interconnecting the guide rails R- 15  and R- 16  of the system to the side portions of connector bracket  820 . In the present form of the invention, this connector means comprises a pair of spaced apart connector clips  890  that are adjustably connected to side  820   b  of connector bracket  820  by threaded bolts  891 . Each connector clip has a rail engagement leg  890   a  that is adapted to clampingly engage the legs of the guide rail R- 15 . 
     Bolts  891  extend through slots  894  provided in leg  820   b  of bracket  820  (FIG. 41) and also extend through apertures  895  provided in a pair of angle brackets  896  that are connected to side  820   b  by the bolts  891  and nuts  891   a  in the manner best seen in FIG.  39 . Brackets  896  include an outwardly extending leg  896   a  that is provided with an aperture  897  that accepts a threaded jackbolt  900 . 
     Each of the previously identified walls  846  that extend inwardly from sides  820   b  and  820   c  are provided with a bore  846   a  that is adapted to receive the shank of a threaded jackbolt  900 . As shown in FIG. 39, jackbolt  900  is threadably received within a series of adjustment nuts  902  that bear upon the surfaces of the outwardly extending legs of brackets  895  and also on the opposing surfaces of walls  846  so that, when the jackbolt is threaded inwardly and outwardly with respect to nuts  902 , clips  890  can be adjusted longitudinally of side  820   b  to adjustably position rail R- 15 . It is apparent that by loosening adjustment nuts  902 , bolts  891  along with clips  890  can be moved toward and away from guide rail R- 15  and can be securely locked in position by retightening the locking nuts. 
     In the present form of the invention, the connector means also comprises a pair of spaced apart connector clips  906  that are adjustably connected to side  820   c  of connector bracket  820  by threaded bolts  907 . Each connector clip has a rail engagement leg  906   a  that is adapted to clampingly engage the legs of the guide rail R- 16 . 
     Bolts  907  extend through slots  909  provided in leg  820   c  of bracket  820  (FIG. 41) and also extend through apertures  911  provided in a pair of angle brackets  912  that are connected to side  820   c  by the bolts  907  and nuts  907   a  in the manner best seen in FIG.  39 . Brackets  912  include an outwardly extending leg  912   a  that is provided with an aperture  914  that accepts a threaded jackbolt  916 . Jackbolt  916  also extends through bore  846   a  one of the previously identified walls  846  that extends inwardly from side  820   c  of bracket  820 . As shown in FIG. 39, jackbolt  916  is threadably received within a series of adjustment nuts  918  that bear upon the surfaces of the outwardly extending legs of brackets  912  and also on the opposing surfaces of wall  846  so that, when the jackbolt is threaded inwardly and outwardly with respect to nuts  918 , clips  906  can be adjusted longitudinally of side  820   c  to adjustably position rail R- 16 . It is apparent that by loosening adjustment nuts  918 , bolts  907  along with clips  906  can be moved toward and away from guide rail R- 16  and can be securely locked in position by retightening the locking nuts. 
     As in the earlier described embodiments, when the apparatus of this latest form of the invention is appropriately installed within the elevator hoistway the various degrees of adjustment available to the installer permit the installer to precisely locate guide rails R- 15  and R- 16  in an optimum position relative to the involved elevator cars. 
     Referring next to FIGS. 42 through 45, an alternate form of a connector apparatus of the invention for use interconnecting a guide rail R- 17  with a supporting structure such as a selected wall of the structure that houses the elevator hoistways is there shown. As best seen in FIG. 43, the connector assembly  960  of this latest form of the invention comprises a first connector bracket  964  having a first generally planar first leg  966  that is connected to the supporting structure “SS”. Leg  966  extends generally perpendicularly from a second leg  967  that has a generally planar surface  967   a . Leg  966  is provided with spaced-apart apertures  968  and  970 . Received within apertures  968  and  970  are the threaded shank portions  972   a  of a pair of anchor bolts  972 , the body portions  970   b  of which are embedded within the concrete of the supporting wall “SS”. The threaded shank portions  972   a  of bolts  972  extend through apertures  968  and  970  and are interconnected with leg  966  of bracket  964  by locking nuts  974 . 
     Leg  967  of bracket  964  is provided with a plurality of first through holes  976  that are disposed along a first line  978  that extends at an acute angle with respect to first leg  966 . Similarly, leg  967  is provided with a second set of through holes  980  that are disposed along a second line  982  that extends at an acute angle with respect to first leg  966 . 
     Adjustably interconnected with first connector bracket  964  is a second connector bracket  984 . Second bracket  984  has a first leg  984   a  and a second leg  984   b  that extends generally perpendicular to first leg  984   a . As best seen in FIGS. 43 and 45, second bracket  984  is also provided with a plurality of through holes  986  that are disposed along a first line  987  that extends at an acute angle with respect to first leg  984   a . Similarly, leg  984  is provided with another set of through holes  988  that are disposed along a line  989  that extends at an acute angle with respect to first leg  984   a . Through holes  986  formed in bracket  984  are so constructed and arranged that a selected one of the through holes  986  can be moved into index with a selected one of the through holes  976  formed in bracket  964  by a sliding movement of bracket  984  relative to bracket  964 . Similarly, through holes  988  formed in bracket  984  are constructed and arranged so that a selected one of the through holes  988  can be moved into index with a selected one of the through holes  980  formed in bracket  964  when bracket  984  is slidably moved from a first position to a second position relative to bracket  964 . More particularly, bracket  984  can be slidably moved relative to bracket  964  in a first direction generally parallel with leg  966  of bracket  964  or, alternatively, can be slidably moved in a second direction generally perpendicular to leg  966  of bracket  964 . 
     When second connector bracket  984  is correctly aligned with first connector bracket  964  and a selected one of the though holes  986  is indexably aligned with a selected one of the through holes  976 , a first bolt, such as a bolt  990 , can be introduced into the aligned through holes. Similarly, when the connector bracket  984  is correctly aligned with bracket  964  and a selected one of the through holes  988  is indexably aligned with a selected one of the through holes  980 , a second bolt, such as a bolt  991 , can be introduced into the aligned through holes. With the bolts  990  and  991  in position with the square shank portions thereof (FIG. 43) closely received within the aligned holes, nuts can be used to securely interconnect connector bracket  984  with bracket  964  in the manner shown in FIGS. 43 and 44. When the brackets are thusly connected, the square shaped shank portions of the bolts will be snugly received within the indexably aligned through holes in the two brackets and will efficiently prevent sliding movement between the brackets. 
     The connector apparatus of this latest form of the invention further includes connector means for connecting guide rail R- 17  to first leg  984   a  of second bracket  984  in the manner illustrated in FIGS. 43,  44  and  45 . In this latest form of the invention, the connector means comprises first and second spaced-apart connector clips  994  that are of a similar construction to the earlier identified connector clips. Connector clips  994  are adjustably connected to first leg of connector bracket  984  by threaded bolts  994   a . Each connector clip  994  has a rail engagement leg  944   b  that is adapted to clampingly engage the legs of the guide rail R- 17 . 
     Bolts  994   a  extend through slots  995  provided in leg  984   a  of bracket  984  (FIG. 45) and also extend through apertures provided in a pair of angle brackets  996  that are connected to side  984   a  by the bolts  994   a  and mating nuts in the manner best seen in FIG.  43 . Brackets  996  include an outwardly extending leg  996   a  that is provided with an aperture that accepts a threaded jackbolt  998 . Jackbolt  998  also extends through a bore  1000   a  provided in an outwardly extending angle bracket  1000  that is connected to wall  984   a  of bracket  984 . As shown in FIG. 43, jackbolt  998  is threadably received within a series of adjustment nuts  1002  that bear upon the surfaces of the outwardly extending legs of brackets  996   a  and  1000  so that, when the jackbolt is threaded inwardly and outwardly with respect to nuts  1002 , clips  994  can be adjusted longitudinally of wall  984   a  to adjustably position rail R- 17 . It is apparent that by loosening adjustment nuts  1002 , bolts  994   a  along with clips  994  can be moved toward and away from guide rail R- 17  and can be securely locked in position by retightening the locking nuts. 
     As in the earlier described embodiments, when the apparatus of this latest form of the invention is appropriately installed within the elevator hoistway the various degrees of adjustment available to the installer permit the installer to precisely locate guide rail R- 17  in an optimum position within the hoistway. 
     Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.
