BACKGROUND OF THE INVENTION 
     (1) Field of the Invention 
     This invention relates to devices for attaching anchors to flanged ceiling rails. 
     (2) Prior Art 
     Hanging displays from ceilings, and changing those displays is a never ending task for merchants, who must change, correct or move displays hanging from ceilings, all the time. 
     Some devices have been created to aid in anchoring of ad displays from ceilings, but often suffer from handicaps as usually requiring stepladders or the like. Among the art included is U.S. Pat. No. 3,327,376 to Freeman et al; U.S. Patent to Ferguson, U.S. Pat. No. 4,135,692; U.S. Pat. No. 4,163,576 to Hoop; U.S. Pat. No. 4,225,108 to Jaroche; U.S. Pat. No. 4,269,087 to Wand; U.S. Pat. No. 4,323,215 to Berger; and U.S. Pat. No. 4,564,165 to Grant et al. 
     They represent devices that are complicated to make, require close hand support or ladders to bring the worker to the ceiling. 
     It is an object of the present invention to provide an anchor installation arrangement for ceiling rails which is simple to use, readily adaptable to a plurality of anchor devices, and which will assist in the removal as well as the attachment of such anchors. 
     BRIEF SUMMARY OF THE INVENTION 
     The present invention comprises an anchor installation device which is attachable to the end of a telescoping elongated pole. The anchor installation device includes a generally &#34;Y&#34; shaped bifurcated support having a proximal end of stepped diameter, which is attachable to the telescoping pole. 
     The bifurcated support is arranged to be matable on its distal end, with several different installation heads. A first installation head comprises an elongated generally U-shaped member adapted primarily for the attachment and removal of magnetic anchors on metal ceiling rails. A second installation head is also attachable to the distal end of the bifurcated support, so as to permit the attachment of &#34;spider&#34; anchors to the metal ceiling rails. 
     The bifurcated support has a pair of elongated fingers having flattened distal ends. One of the fingers has a boss which mates with a similarly configured slot on the installation heads so as to establish proper mounting therebetween. 
     The first installation head, of elongated generally U-shaped configuration has a central body portion with a pair of spaced apart slots for receiving the flattened ends of the elongated fingers of the bifurcated support. One of the slots has a recess which mates with the boss on one of the fingers. 
     The first installation head has an open first end having parallel side rails, which are appropriately spaced so as to receive an elongated rectangularly shaped magnet. The installation head has an upper side having upper teeth extending partially towards one another off of the rails so as to grip a magnet and permit it to be pulled from a metal ceiling rail. The installation head has a lower side having lower teeth extending toward one another off of the side rails so as to hold a magnet between the rails as it is being lifted toward the ceiling rail. A pair of tabs extend off of the lower distal most teeth to prevent an elongated magnet held therein from sliding out the open end of the elongated side rails. 
     The first installation head also has a bifircuted second end. A transverse channel is disposed across the body. An elongated magnet may be held in the transverse channel. The elongated magnets have a centrally disposed hook extending off of one side. The hook would extend into the slot defining the bifurcation, which is directed, permitting attachment of a sign or display arrangement to the hook. 
     A circular depression in the upper surface of the second end is adapted to engage a circular adhesive pad. The adhesive pad has a boss on its lowermost side from which a hook would extend. The hook would fit into the aforementioned slot in the second end, enabling a display to be attached thereto. 
     A hook may be disposed on the outer side of the elongated side rails, to lift displays onto the hooks extending downwardly from the magnets or adhesive anchors. 
     The second installation head is comprised of a generally planar U-shaped fixture having a base of somewhat square configuration. An elevated boss is disposed on each corner of the base. A slot extends down the center of the base defining a pair of spaced parallel legs. A central portion on each side of the slot has sloped sides. A planar ear extends off of the base from each leg. A narrow groove extends transversely across the legs, including the sloped sides on each side of the slot. The groove is adapted to snugly receive a spider clip which is arranged to grip a T-shaped ceiling rail when twisted thereon. The elevated bosses on each corner of the base push up ceiling tiles out of the way slightly so that the spider clip can engage the ceiling rail without interference. 
     The first and second installation heads are interchangable with respect to the bifurcated support/each permitting its own type of anchor to be secured to the ceiling rail with relative ease.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings in detail, and particularly to FIG. 1, there is shown a bifurcated support 20 which is adaptable for emplacement onto a telescoping pole 19, for securement of an installation head utilized to attach anchors to ceiling rails. This invention is related to the invention shown in commonly assigned U.S. Pat. No. 5,052,733, which is incorporated herein by reference. 
     The bifurcated support 20 has a proximal end 22, of stepped diameters 21 and 23, adapted to be received in different size openings, if necessary, on the distal end of the telescoping pole 19, and is arranged to be matable, on its distal end, to different installation heads 24 and 26, shown in FIGS. 2 and 5, respectively. The first installation head 24, shown in FIG. 2, comprises an elongated generally U-shaped member, adaptable for the attachment of magnetic anchors 28, generally as shown in FIG. 9. 
     The bifurcated support 20 has a pair of elongated fingers 30 and 32 having flattened distal ends. One finger 32 has a narrow elongated key 34 on one side thereof, as shown in FIG. 1, which mates with a similarly configured slot on each of the installation heads 24 and 26 as described herein below. 
     The first installation head 24 has a central body portion 36 with a pair of spaced apart slots 38 and 40 adapted to receive the flattened distal ends of the elongated fingers 30 and 32 of the bifurcated support 20. One of the slots 40 has a recess 42 which mates with the key 34 on one finger 32. 
     The first installation head 24 has an open first end 44 having parallel side rails 46 and 48. The first installation head 24 has an upper side 50 and a plurality of short, spaced apart upper teeth 52 extending off of the upper side 50 across the space between the side rails 46 and 48, and towards one another, as shown in FIGS. 2 and 4. The first installation head 24 has a lower side 54 having short, spaced apart lower teeth 56 extending towards one another off of the bottom side 54 of the side rails 46 and 48. A tab 58 extends slightly upwardly of and distal of the distalmost lower tooth 56, the upper and lower teeth 52 and 56 acting to hold a magnetic type anchor 28 therebetween, as it is lifted towards or away from a ceiling rail 60, of inverted T-shape in cross section, which ceiling rail 60 is shown in FIG. 10. 
     The first installation head 24 also has a bifurcated second end 62, as shown most clearly in FIG. 2. The second end 62 is bifurcated by a central slot 64. A transverse channel 66 is disposed across the central body portion 36, which likewise is dimensioned so as to cradle an elongated magnetic anchor 28, thereacross. The magnetic anchors 28 typically have a boss 68 centrally disposed therein, as shown in FIG. 9. A hook 70 or eye extends outwardly from the boss 68. During installation of a magnetic anchor 28, the boss 68 and hook 70 would extend downwardly through the slot 64 as it is lifted towards a ceiling rail 60. 
     The second end 62 of the first installation head 24 may have a circular depression 72 extending thereon, which permits the first head 24 to engage a circular adhesive anchor, not shown, having a boss and hook directed downwardly through the slot 64 as would the boss and hook of a magnetic anchor 28. A leader or elongated line may extend from the respective hooks of the anchors, to any display sign thereattached. 
     An engagement hook 74 is arranged in the outer side of each side rail 48 and 46. The engagement hook 74 permits the emplacement and removal of display sign lines onto the anchor hooks through the manipulation of the first installation head 24 on the upper end of a telescoping pole, not shown. 
     The second installation head 26, as shown in FIGS. 5 and 6, is comprised of a generally square shaped planar base 76, having an elevated boss 78 on each corner thereof. A slot 80 extends across most of the base 76, and defines a pair of spaced apart parallel legs 82 and 84. A central portion 86 on each side of the slot 80 is of sloped configuration. A planar alignment ear 88 extends angularly off of each side of the base 76. The alignment ears 88 provide an alignment means when the second head 24 is attached to its bifurcated support 20. The ears 88 are caused to line up parallel to the lower portion of the ceiling rail 60. A narrow groove 90 is molded across each leg 82 and 84 as shown in FIG. 5, including the central sloped portion 86. The groove 90 is configured to snugly receive a spider clip 92, which clip 92 is shown in FIGS. 7 and 8. A pair of feet 94 extend downwardly on the bottomside of the base 76 at the legs 82 and 84, as shown in FIG. 6. A pair of slots 95 and 97 are molded into the feet 94, which receive the elongated fingers 30 and 32. 
     When attaching a spider clip 92, which mates with the groove 90 in the second head 26, the clip 92 has sloped portions 93 which mate correspondingly with those sloped portions 86 of the groove 90. The alignment ears 88 are manipulated into alignment with the longitudinal axis of the ceiling rail 60, and then the head 26 is rotated so as to engage the bent ends 96 onto the inverted &#34;T&#34; ceiling rail 60. The elevated bosses 78 on each corner of the second head 26 push the ceiling tiles 98 up out of the way slightly, as the spider clip 92 is being rotatively engaged thereon, without interference from those tiles 98. 
     The first and second interference heads 24 and 26 are interchangably disposable with respect to the bifurcated support 20, each permitting its own arrangement of ceiling anchors to be secured to a ceiling rail, with relative ease.
