This lever is supported on the pivot pin 2U, which extends through the bear ings IB and I'I and through the lever, and is pro wire rope may be clamped by the operation of a 5 vided with a screw thread 20a to engage the bear lever, and by continued pressure on the lever may ing I6, and a head 20h to engage the bearing I'I. be turned to untwist or twist the strands of the The lower end of the lever is formed with a wire rope or cable. lateral foot or jaw ZI, which is provided with Another object of the invention is to provide a clutch teeth 2Ia, to engage the wire rope, indi device of this character, with a stationary bearing cated at R. These teeth are disposed in a convex in which the twisting device may be mounted so curve and the foot or jaw 2| is offset relative to that a left twisted wire rope or cable or a right the major axis of the lever, the pivot pin and the twisted wire rope or cable may be manipulated.> bearings IS and I'I being disposed to one `side of With the above and other objects in view the the vertical plane deñned bythe rope receiving invention comprises certain newand useful con 15 slot or groove I5. structions, combinations and arrangements of The wire rope or cable to be twisted or untwisted parts, clearly described in the following speciñca- . is passed through a standard clamping device or tion, and fully illustrated in the drawing, in vise 22, mounted on a stationary support 23, lo which: Y lcated at a suitable working distance from the Fig. 1 is a view in elevation, showing a -wire 20 standard 5. rope engaged by the manual twisting tool. By swinging the lever to the right in the posi Fig. 2 is a side elevation of the stationary bear tion shown in Fig. 4, the lateral foot or jaw 2| ing, showing the twisting device mounted therein, will be forced into clutching relation with the the lever being broken away for convenience. rope or cable, and by continuing the movement Fig. 3 is an enlarged edge view, the lever being 25 of the lever in the same direction, the rope will broken away. be subjected to a twisting or untwisting opera Fig. 4 is a view partly in elevation and partly tion, depending on whether the wire rope or cable in vertical section, taken on line 4_4 of Fig. 3, has a right or left twist. The cable is subjected looking in the direction of the arrows. to continued twisting, by` turning the entire 30 Fig. 5 is a side elevation, the lower standard twisting device, including the base I3 and the being broken away. Fig. 6 is a side elevation of the base of the lever I9 in one or more complete circles on the bosses 9 and I0 of the stationary bearing sup port l. By reversing the position of the twist ing head and lever on this support, by withdraw ignates a vertical support or standard, having a 35 ing the stub shaft I2 and inserting the stub shaft base 6. On the upper end of this support the I4, the device may be adapted for handling a plate 'I is attached -by the bolts 8. left twisted wire rope or cable. The plate 1 is formed with integral bosses 9 My invention will be found extremely` useful and I0, which are formed with a slot II, and the in connection with the repair and splicing of plate 'I is also formed with an upwardly extend 40 wire cables, and enables one man to either open ing slot la, which registers with the slot II, the up the twisted strands of the wire rope or cable, upper end of which widens. ` or to close these strands to produce the correct The horizontal slot II is constructed to receive lay of the strands upon the rope or cable, and ' the trunnion or integral stub shaft I2 of the to insure uniform diameter and ñow of the com twister base I3, which is also formed with another 45 pleted cable or rope, when subject to load oper twister. Referring to the accompanying drawing 5 des trunnion or integral stub shaft I4 on .the oppo site side thereof. The base is also provided with bearing faces I 3a and I3b which are adapted to have flush bearing against the end face of the ations of all character. ` It is understood that various changes in the details of construction, their combination and arrangement, may be made, and various mate boss I0. The base I3 is also formed with a groove 50 rials used in carrying out the invention, as de I5, which extends through the stub shafts I2 and fined by the claims herein set forth.` I4, which is adapted to receive a wire rope or i Having described the invention, I claim as cable. new: The base I3 is formed with opposing bearings I6 and I'I‘, which‘are spaced from each other to 55 l; A Wire rope twister, comprising a station ary bearing, a base having a slotted stub shaft -l i" 2,412,795 3 mounted to turn in the bearing, and a lever piv-oted on the base and provided with a jaw adapt ed to clamp a wire rope in the slotted stub shaft. 2. A wire rope twisting device, comprising a stationary bearing, a base having a slot therein to receive the wire rope to be subjected to twist ing, and a lever pivoted on the base and adapt ed to clamp the wire rope in the slot, the base being mounted to turn _inthe bearing. 3. A Wire rope’ twisting device, comprising a stationary bearing, Isaid bearing having a verti cal slot to receive a wire rope, a base having a slotted stub shaft mounted to turn in the bear ing, a lever pivoted to the base and` provided with a curvedangular jaw formed with teeth to bite into the rope and clamp the same so that 4 by turning the lever and the base the rope may betwisted or untwisted. 4. A wirerrope twisting device, comprising‘a stationary bearing having a slot therein, a vise for holding a wire rope against turning, a. base having stud shafts on opposite sides thereof, either of which may be mounted in the bearing, said base having a slot intermediate of said stub shafts and said stud shafts >having a wire rope - receiving slot, and a vlever pivoted inthe slot 'of the base and provided with a curved angular> jaw on its lower end adapted to engage a wire rope and clamp the same against turning in said slotted stud shafts and to permit of the turning of the base on said stationary bearing. , ' ~ ARNE C.
