     BACKGROUND OF THE INVENTION 
     The present invention relates to an apparatus for stripping an insulated electric wire. More specifically, the invention relates to an apparatus for stripping a three-wire, armor covered, lead jacketed, insulated electrical cable. 
     Presently known commercially available cable stripping machines handle one stripping operation at a time. Such machines require considerable handling of the cable and considerable equipment. Such machines are generally designed for high speed operation and require numerous speed controls. The present invention provides a relatively slow speed apparatus which is effective, simple to operate and does not require expensive controls. 
     Various types of apparatuses have been devised to strip insulated wire. Some of the more recent different types are illustrated by U.S. Pat. Nos. 4,051,749; 3,964,142; and 3,994,188. These devices are all quite different from the instant invention. 
     Also, such presently known commercially available cable stripping machines cannot handle flat, armor covered, lead jacketed, insulated cable without substantial modification. 
     It is therefore a primary object of the instant invention to provide an apparatus or assembly which will strip a flat, parallel three-wire, armor covered, lead jacketed, insulated cable in a continuous operation. 
     Another object of the present invention is to provide a cable stripping apparatus, wherein the various components of the cable such as steel (or other armor), lead (or other similar type jackets), rubber (or other insulation) and copper (or other electrical wire) can be easily reclaimed as separated materials. 
     A further object of the invention is to provide a cable stripping apparatus which can be easily adjusted to handle various sizes of armored electrical wire or cable. 
     Still another object of the present invention is to provide a cable stripping apparatus which is relatively inexpensive and which can be easily operated. 
     Other objects and advantages of the present invention will become more readily apparent from a consideration of the description and drawings hereinafter. 
     SUMMARY OF THE INVENTION 
     The present invention is directed to an apparatus for stripping an armored cable or electrical wire, particularly, a flat, parallel three-wire, armor covered, lead jacketed, insulated cable. The apparatus comprises a stripping means which includes cable guiding means, a plurality of adjustable blades or cutting means, an armor removal means, a lead stripping means, and an insulation stripping means, a cable pulling means for pulling the cable from a feed means through the stripping means, and a means for feeding the cable into the stripping means.

The blades are in parallel alignment with each other and spaced apart to provide a desired cutting location. Locking nuts 63a and 63b are provided for locking the blades on the shaft. Shaft 63 is positoned in pillow blocks 64 and 65 which are suitably attached to plate 61. Roll pins 66 and 67 are suitably attached to each end of shaft 63 and inserted in pillow blocks 64 and 65, respectively. A large chain sprocket 68 is attached to one end of shaft 63 and held thereon by set screw 68a. A small chain sprocket 69 is also attached on shaft 63 between sprocket 68 and block 64. 
     Also mounted on plate 61 are pillow blocks 161 and 162 with shaft 163 positioned therein. A movable coller 164 with circular saw blade 165 fixed thereon is installed on shaft 163 between pillow blocks 161 and 162. The collar and blades may be moved along the shaft to position the blade in a desired cutting position. A small chain sprocket 166 is attached to one end of the shaft 163 exterior of pillow block 162 and in alignment with small sprocket 69. 
     Motor M in motor mount M&#39; on frame support members 38a and 38b has a drive shaft 142 on which chain sprocket 143 is attached to an end thereof. Sprocket 142 and sprocket 68 are operably connected together by chain 144. Sprocket 69 and sprocket 166 are operably joined together by small chain 145. 
     The motor M is preferably an electrical one and includes suitable electrical connections and switches therefor. The motor could also be a gasoline type or any other suitable type. Motor M and its associated shafts, sprockets, chains and related parts provide the driving force for rotating cutting blades 62 and cutting blade 165. Motor cover 39 and sprocket cover 146 provide protective shielding of moving parts. 
     Cutting unit 60 also includes a cable guide unit or assembly 150 (FIG. 8) which is mounted in plate 61 below cutting blades 62. The unit 150 comprises an adjusting block 151 with adjusting screw 152 threadedly engaged therein by means of threaded opening 151a. Screw 152 extends through an opening 61a in plate 61 and is removably attached to cable guide 153 by means of bearing 154. Four coil springs 155 are inserted in channels or openings 154a therefor in cable guide block 153. A cable guide 156 is positioned on cable guide block 153. Guide 156 has a channel 156a therein for receiving cable 20. The cable guide 156 is cut and sized for the particular size cable to be stripped. It is removable, and cable guides suitable for use with other size cables can be substituted therefor. 
     Angle iron guide members 157 and 158 are attached to the upper side of plate 61 and retain cable guide block 153 in position and enable said block to be moved vertically within the confines thereof. 
     Armor removal unit 70 is mounted on bar 71 attached to frame members 35 and 36 and in alignment with cutting blades 62 and 165. As best seen in FIG. 13, the armor removal unit 70 comprises a pair of paralleledly spaced apart armor stripping members 72 and 73 bolted or otherwise suitably attached to mounting members 74 and 75 (not seen), respectively, suitably fixed or positioned on the bar 71. Stripping members 72 and 73 are substantially identical. Member 72 has a more or less flat face 72a for contacting and stripping away the outer steel armor of the cable 20. Preferably, the member 72 also has a tapered edge 72b. The members 72 and 73 are so positioned in relation to each other and the cable 20, that as the cable 20 is pulled toward the unit 70, the steel armor is stripped from the cable so as to divide the cable into its three separate lead jacketed wires. One wire passes outwardly of the member 72, one wire passes outwardly of member 73 and the center wire passes between the members 72 and 73. 
     Lead shield removal unit 80 is mounted on bar 81 attached to frame members 35 and 36. As best seen in FIG. 11, unit 80 includes three spaced apart lead stripping members 82 removably secured by screws or other suitable means to support bar 83. Each of the members 82 has a semi-circular shaped channel or groove 82 extending across the upper side thereof which is sized for the cable being stripped. Different size lead stripping members are used for different sizes of cable. One edge or face 82b of the members 82 is tapered or slanted. The members 82 also preferably have a notched or cut-out portion 82c on the upper edge thereof. 
     Rubber stripping unit 90 includes bar 91 suitably attached to frame members 35 and 36 with roller 92 mounted on shaft 93 the ends thereof which are removably positioned in suitable openings in shaft support members 94 and 95. Roller 92 has three parallel grooves therein sized to the particular sized cable of which the rubber or insulation is to be stripped therefrom. 
     The unit 90 also includes bar 96 on which three rubber stripping means 97 (FIG. 12) are attached thereto in a spaced apart parallel relationship. Rubber strippers 97 are also sized to the particular cable being stripped. Various size strippers may be interchanged as desired. Each of the members 97 has a somewhat pointed edge 97a which is shaped so as to strip the rubber from the cable wires. The other stripping members 97 are substantially identical and are positioned on the bar 96 in a parallel and spaced apart manner so that each edge 97a will strip the rubber insulation from the three rubber insulated wires as the wires are pulled past the strippers 97. 
     Preferably, the stripping unit 90 also includes three cutting blades 98 which are mounted paralleledly and spaced apart on a shaft 98a in the somewhat U-shaped mounting bracket 99 positioned on top of the members 97 and attached to bar 96. The blades 98 are positioned so that they are aligned with the saw cuts in the insulation on the respective wires directed there towards. The blades 98 assure that the rubber insulation is fully cut should the saw cuts be inadequate for subsequent stripping of the cable. 
     Referring now to FIGS. 9 and 10, puller assembly D comprises frame 100, pulling unit 110 and motor 120. Frame 100 is positioned adjacent from 30, particularly adjacent legs 33 and 34 thereof, and includes legs 101, 102, 103 (not seen) and 104 (not seen), lower frame members 105 and 106 (not seen), upper frame members 107 and 108 (not seen) and upper cross members 111 and 112. Legs and frame members not seen are comparable to their opposite leg or member shown. 
     Motor 120 is supported by motor unit 121 fixed to frame members 105 and 106. The motor is preferably an electric one, but could be any suitable type, such as a gasoline motor or other type. The motor also includes the usual electrical connections and switches necessary for the operation thereof. The motor 120 has a drive shaft on which is mounted a sprocket. A chain 122 is connected to the motor sprocket and to pulling unit sprocket 113 mounted on shaft 114. Drive roller 115 is positioned on shaft 113. Roller 115 has a knurled surface thereon. Shaft 113 is positioned in pillow blocks 116 and 117 attached to the underside of angle frame members 107 and 108, respectively. 
     Pulling unit 110 also includes a pair of upper rollers 118 and 119 mounted on shafts 210 and 211, respectively. Shaft 210 is supported by pillow blocks 212 and 213 positioned on the upper side of frame members 107 and 108, respectively. Shaft 211 is supported by pillow blocks 214 and 215 also positioned on the upper side of frame members 107 and 108, respectively. Pillow blocks 212 and 213 are attached to turnbuckle screws 216 and 217, respectively, which are threadedly engaged in turnbuckle mounts 218 and 219, respectively fixed to the upper sides of frame members 107 and 108, respectively. Pillow blocks 214 and 215 are attached to turnbuckle screws 220 and 221, respectively, which are threadedly engaged in screw mounts 222 and 223 also attached to the upper sides of members 107 and 108, respectively. Rotation of the various turnbuckle screws moves the rollers 118 and 119 horizontally and inwardly or outwardly as desired. 
     The cable to be stripped is a three-wire armor covered, lead jacketed, insulated flat cable. Such a 3-phase wire armored cable typically includes three multi-strand copper wires individually insulated in the usual manner with rubber such as EPDM. The three insulated wires are encased or surrounded by a lead jacket. Around the lead jacket is a braided material such as a woven cloth. Around the woven cloth is an insulating tape such as PVFT. Finally, the entire assembly is encased or surrounded by an armored jacket of steel. In some instances, an insulating tape may also be wrapped around the steel armor. 
     As seen in FIG. 14, the cable 20 includes three separate multi-strand wires 20a, 20b and 20c. Each of the wires is covered with rubber or other suitable insulation 20d, 20e and 20f, respectively. Around the rubber on each wire is lead jackets 20g, 20h and 20i, respectively. Around the lead jackets of each wire is an insulated tape covered woven or braided cloth 20j, 20k and 20l, respectively. Finally, a steel armor 20m encases or surrounds the three covered wires. In the drawing, some of the components of the cable are exaggerated for purposes of illustration. Such types of cables are well known in the art. 
     It can be appreciated that such a cable may be manufactured in a variety of ways using various materials. Basically though such cable includes three insulated electric wires which are separately encased in a lead jacket and which lead jacketed wires are protected by an outer armor. For purposes herein, the term &#34;cable&#34; means any type of lead jacketed, armored cable. The terms &#34;copper wire&#34; or &#34;wire&#34; means any suitable wire of one or more strands of electric conducting material. The terms &#34;rubber insulation&#34; or &#34;rubber coated&#34;, &#34;rubber&#34; or any combination thereof means any suitable insulation material placed around the copper wires. The term &#34;lead jacket&#34; means any type of jacketing material encasing the insulated copper wires such as lead, lead alloy or similar types of materials. The term &#34;armor&#34; or &#34;steel&#34; or any combination thereof means the outer protective casing or covering which is made of steel or any other suitable materials. The term &#34;woven cloth&#34; means any type of braided material or other material which may be used for such purpose. The term &#34;tape&#34; means any type of insulating or other tape which may be used for such purpose. 
     Although the apparatus illustrated is particularly constructed for stripping a 3-phase armored cable, it can be appreciated that the apparatus can be readily varied to strip a cable having any number of wires. More or less cutting or saw blades, lead stripping members or dies, lead shield removal members and rubber stripping members can be installed as desired. Parts of the apparatus necessary to handle a particular size of cable can readily be installed. 
     In the operation of the apparatus of the instant invention, the apparatus must first be adjusted to handle the stripping operation of a particular size armored cable. 
     In the guide roller assembly 50, adjustable guide rollers 43 and 44 are positioned so that they are spaced apart sufficiently to enable the cable 20 to be guided thereby and readily pass therebetween. Upper roller 130 is vertically adjusted so that the cable will be guided by and readily move between rollers 130 and 131, over lower roller 131 and under upper roller 130. Movable roller 51 is horizontally adjusted so that the cable may be guided by and readily moved between roller 51 and fixed roller 52. The cable also passes through hold down guide 59. With the foregoing adjustments, the assembly 50 is ready to guide the cable 20 into the proper position for cutting and stripping operations. 
     In the armor cutting unit 60, the three saw blades 62 are positioned so that three parallel and suitably spaced apart cuts may be made longitudinally in the cable 20 so as to cut from the upper side of the cable down to the copper wire, i.e., so as to make three distinct cuts through all parts of the cable except the copper wire. The fourth saw blade 165 is adjusted so that the cable may be cut longitudinally from the bottom through the steel armor. This latter cut is preferably made more or less in the center of the cable; however, such center position is not critical. A cable guide 156 of a proper size to guide the cable 20 therethrough is positioned under the blades 62. The guide 156 is adjusted to proper height for cutting the cable by means of adjusting screw 162 which raises or lowers cable guide block 153 as necessary. 
     Armor removal unit 70 is positioned so that the steel armor may be removed from the cable 20 after the cable has been cut by blades 62 and 165. 
     The lead shield removal unit is adjusted so that the lead shield around the cable 20 may be stripped therefrom after the cable has passed through the armor removal unit 70. 
     Rubber stripping unit 90 is also adjusted to a proper position to enable the rubber insulation to be stripped from the cable 20 after the cable has passed through the lead shield removal unit 80. 
     After the various components of the apparatus A have been adjusted or positioned for receiving and handling a particular size of flat armored cable, one end of the cable 20 is fed from the reel 22 between guide rollers 43 and 44 and between rollers 130 and 131. The roller 131 is then turned by means of hand crank 137 and drives the cable 20 forward between rollers 51 and 52 and into cutting position. Motor M is actuated so that the rotary blades 62 and 165 make the desird cuts in the cable. The cable is then pulled thru the armor removal unit 70, which strips the steel armor from the cable as it is moved forward. The cable is pulled forward thru the lead shield removal unit 80 which strips the lead shield from the cable. The cable is then hand stripped of the rubber and fed thru the rubber stripping unit 90. The cable is pulled forward and the three wires are fed into the pulling unit D. The wires are fed over the roller 118, under roller 115 and over roller 119. The rollers 115, 118 and 119 are adjusted so that the 3 wires are firmly held and can be moved therethrough. Operation of the motor 120 drives rollers which pull the wires forward where they can be wound on a suitable reel or other container. 
     Once the wires are positioned in the pulling unit, operation of the motor 120 causes the cable to be pulled from the reel 22 and through the various cutting and stripping operations. The operation is continued until all or a desired amount of cable is stripped. 
     As best seen in FIG. 13, a portion of the cable 20 is illustrated after the cable has passed through the armor cutting unit 60. The saw blades 62 have made three distinct cuts 20x, 20y and 20z from the top down through armor 20m, through taped cloth 20j, 20k and 20l, through lead jackets 20g, 20h and 20i, through rubber insulation 20d, 20e and 20f, and to wires 20a, and 20b and 20c. Saw blade 165 has made bottom cut 20p which extends thru armor 20m. 
     As the cable 20 is pulled past the armor stripping unit 70, the faces 72a and 73a and of the members 72 and 73, respectively, force the armor 20m from the cable 20 so as to fall away in pieces 20m&#39;, 20m&#34;, etc. Three separate covered wires as illustrated by taped cloth covering 20j, 20k and 20l emerge from the unit 70. 
     As seen in FIG. 11, the three separate taped cloth covered wires 20j, 20k and 20l are pulled through the lead shield removal unit 80 so as to strip lead jackets 20g, 20h and 20i and their respective covering 20j, 20k and 20l from the wire. Three separate rubber covered wires as illustrated by rubber insulating 20d, 20e and 20f emerge from the unit 80. 
     As seen in FIG. 12, the multi-stranded wires 20a, 20b and 20c are pulled thru the rubber stripping unit 90, rubber insulations 20d, 20e and 20 are removed. Blades 98 are positioned so that a blade is aligned with each of the cuts 20x, 20y and 20z, respectively. Each blade cuts any rubber not cut by the saw blades 62 down to the wires 20a, 20b and 20c, respectively. This assures that all rubber insulation will be stripped from the wires. 
     The apparatus A enables flat armored cable to be completely stripped with relative ease. Adjustments can readily be made to handle a particular size cable. 
     The foregoing disclosure and description of the invention is illustrative and explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction, may be within the scope of the appended claims without departing from the spirit of the invention.
