CABLE-GRIP FOR CARS.

SPECIFICATION forming part of Reissued Letters Patent No. 10,821, dated March 22, 1887. Original No. 353,361, dated November 80, 1886. Application forreissuc filed February 28, 1887. Serial No. 229,262.

To all whom it may concern: composed of a shell, 0, of wrought, cast, or Be it known that I, THOMAS KERR, of the sheet iron, filled with afilling, c, of Wood, lead, city, county, and State of New York, have inbrass, vegetable fiber, leather, or other soft vented a new and Improved Gable-Grip for metal or non-metallicmaterial,so that thejaws 5 Cars, of which the following is a full, clear, will present a grasping-surface to the cable TV and exact description. which will not materially abrade or chafe it.

I hinge, preferably by means of the hooks a a, so that when raised they willlift the cable up the jaws C O'of the grip. The jaws O are each between the jaws O C. For operating the f and the hinge-plate J,

wheels D I) in this inanner tliatis, for opening and closing them l employ in this instance a vcrtically'movable hinge-and-togglc arrangement consisting of the toggle-levers f attached to thelower end of the Verticallyanovable bar or plate J. The levers ffare attached at their lower ends to the suspending arms or plates (Z (Land then crossed and hinged at their upper ends to the plate J, so that when the rod or plate J is forced downward levers f will act to spread the wheels I) D, and when raised will act to close or draw them together. The plate J works between the two vertically-i'novable plates H, and reaches down through an opening,j, in plate G- to the plate J, so that this latter plate is held immediately below the plate G.

In the jaws O (J are journalcd in the openings c c the horizontal wheels K K, preferably two in each jaw, the wheels in one jaw being placed opposite to those in the other, and the wheels are concaved at the edges,as shown in the drawings, to fit and grasp the cable,and the concaved edges of the wheels K reachinto the grooves c made in the filling material a of the jaws to receive the cable, so that the wheels when the jaws are closed will grasp' the cable first, and to permit the rollers K to yield and allow the jaws themselves to close upon the cable, I elongate their bearings and place in the same rubber or other springs 7:, as shown in Fig. 9. By this construction the wheels will be forced outward by the spring with sufiicient force to grasp the cable and start the car, and then (the car being started) the jaws will be closed,so that the solid portions of the jaws will grasp the cable with a dead grasp and effecta very secure and firm grip on the cable, so that there will be no danger of the cable slipping. The wheels K serve as a yielding or rolling grasp, so that the car partakes of the motion of the cable gradually, and these wheels prevent the cable from being marred and injured by the jaws.

The hollow frames L,together with the framepieces B, will be secured to the bottom of the car by suitable timbers, and the bars or plates F, H, and J pass up through the frames 13 L, so that they may be raised and lowered by levers and connections above the frame L,which are not shown, as they form no part of my present invention.

In order that no difficulty will be experienced with the grip in passing curves in the track and cable, I form hinges B B and L L in the frame-pieces B and L, respectively, as shown in Fig. 1, so that the elevating and gripping mechanism may swing to the right l or left, to take and .l'ollow the cable independent oi" the main body of the main i'ran'ic of the grip.

Having thus dcscril'icd my invention, what 1 claim as new, and desire to secure by Letters llatcnl', is-- 1.. The combination, wit-h. the jaws or grasping devices of a cable-grip and a verticallymovablc lilting device, of toggle-levers for opening and closing the lifting devices, substantially as and for the purposes set forth.

2. The combination, withliftingwheels and hinged arms carrying the same, of a sliding bar and toggle-levers connected to .said bar l and hinged arms,substantially as herein shown i and described.
