To aZZ whom it may concern.-

Be it known that I, J orrn H. PENDLETON, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Traction Devices for Cable Railways, of which the following is a specification.

This invention is for guiding the endless cable as it is raised and passed between the gripping apparatus, and for applying the power necessary to grip such cable gradually and start the car or to release the grip and stop the car.

In the drawings, Figure l is a general plan of the gripping device beneath the car, the position of the car to the same being indicated by dotted lines. Fig. 2 is a side view of the gripping apparatus. Fig. 3is an elevation in smaller size of a car-truck, the lower part of a car, and the gripping device. Fig. 4 is a separate plan of the truck, a portion being broken off. Fig.5 represents the guide-wheels on the truck for the cable, and Fig. 6 is a side view of the same. Fig. 7 represents the clamping-wheels endwise of the cable. Fig. 8 is a cross-section at or about the line a: :0 of Fig. 1, and Fig. 9 is an elevation of the divided cablesupporting wheel and the devices for holding the same. Fig. 10 is a plan of the parts, partially in section; and Fig. 11 is a vertical cross section at line g; of Fig. 9.

A portion of the ear is represented at A, and B B are the supporting-wheels in truckframcs 0, which wheels and frame may be of any desired character, except that the truckfrarne is to be adapted to the reception of the vertical grooved wheel D, that is upon a horizontal axis in the frame (2, so that the rope or cable E will run along beneath and in contact with said wheel D; and F F are grooved rollers, with directing-cones upon their under surfaces, that serve to deflect or guide the cable in between themselves and into the groove in the wheel D. Those rollers F are supported in the frame cl, that is attached to the truck-frarne O, and at each side of the center line of the truck are guide-plates k, with an opening between them that issufficientfor the cable to pass freely in when being raised up between the rollers F F. These guide-plates k are inclined upwardly at the end portions, as shown, so that there is no risk of the cable being caught or obstructed.

One of the peculiarities of this invention relates to the cable being lifted up into the clamping device under the middle of the car. At the terminal stations each car is usually disconnected from that part of the cable going in one direction and switched into the desired place on the other track. There the car is connected to the part of the rope going in the other direction by lifting said rope up into the clamping apparatus. WVhen the rope is lifted by any suitable wheels and levers, it is raised up between the wheels F F and against the under side of the wheel D upon each truck, so that the cable can be lifted high enough to be grasped by the grip, hereinafter described, and when the car is standing still or moving at a less speed than the cable the wheels D FF will revolve and prevent undue friction. These wheels D prevent the cable running in contact with the axles of the trucks, and at the same time allow such cable to be bent upwardly sufficiently to reach and pass over the supporting-wheels K in front of 7 and behind the gripping apparatus. If these wheels K were made in one piece, there would be difficulty in passing the cable into the grooved periphery and in supporting the wheels. I therefore make each wheel Kin two parts, the division being perpendicular to the axis and in the bottom of the groove.

I will describe one of these wheels K and its supporting devices,the second wheel,K, which islocated at the other side of the gripping apparatns, being the same in its construction and mode of operation. 7

The halves k k of the wheel K are upon the ends of short shafts 7c 75 within tubular-bearings h ld, and to these bearings the links Z Z Z o Z are connected, and these at their upper ends are pivoted to the under side of the car by the shafts l and the bearing beams or flanges Z Z and in order to brace the links against. lateral motion under the strain incident to 5 the cable running over the wheel K, I make use of the braces m, that extend down diagonally from such shafts l to the sides of the links, as

seen in Fig. 11. It will now be understood that the parts of the wheel K can be separated by swinging the tubular bearings k L apart and carrying with them the respective halves k of the wheel, the links Z Z Z Z allowing for this swinging movement, and in order to give motion to the parts and to hold them in either position to which they may be moved I employ any suitable set of cranks or links, preferably those shown, wherein 11 is a rockshaft running along the car and having an arm, n, or lever at one end, to be operated by the attendant at the platform of the ear, and n is a crank-arm for one of the divided whrels, K, and there is a crank-arm for the other divided wheel, K, and from these cranks pass t9 each swinging frame the links a, being conneeted at 6 to thelinks n n, so that when the shaftnis partially revolved and the pivotal connection 6 raised up the links Z 1 will be pressed in one direction by the links a and the links 1 Z will be drawn in the other direction by the links of, thereby swinging the tubular bearing k k apart, separating the two halves 7c 70 of the wheel and allowing the cable E to drop. The reverse movement is to be given to the parts after the cable has been raised up be tween the two parts is k of the wheels and elevated above said wheels, so that the cable will thereafter be supported by the wheels,the two parts being closed together, and in conse quence of the pivotal connections between the links Z and a and Z and n being in line with the pivot 6 the two parts of the wheel K cannot separate without some of the parts breaking, and in order to insure the proper position of the respective parts I provide upon the bearer Z a downward projection at Z, that occupies a central position between the links Z P, and against the sides of which such links Z Z swing when the cable is supported by closing the two parts of the wheel K.

WVhen the car is standing still, the cable E runs in astraight line over the wheels K K, and between said wheels I apply the clampor gripping apparatus, which is constructed as follows: Attached to the under side of the car are brackets P P, and there is a plate, P, passing across between these brackets and bolted to their inner faces. The cross-shaft I is in hearings in the brackets P I, and, passing through said brackets, receives upon its ends the gear-wheels p, and these gear into the respective wheels upon the ends of the screws q, hereinafter referred to. In order to rotate the shaft 1? and the gear'wheels connected to the same, I make use of shafts r 1, extending to the respective ends of the car, so that the same can be rotated from either end of the car by bevelgearing R and by a shaft, 0, to the upper end of which a hand-wheel is applied, and there are bevel-gears at R to connect the shaft 1 to the respective shafts r 1-. By this arrangement of gearing the attendant can apply the grip to the cable from either end of caror take off said grip. The screw-shafts q q are made with right and left handed screw-threads acting upon the grip-blocks s s. which-blocks are suspended from the plate P by suitable screw-bolts, s", and the plate P is' slotted for the passage of the bolts, so that the grip-blocks s s can be moved toward or away from the cable for gripping or releasing said cable. I also provide wheels placed in pairs at opposite sides of the cable. The wheels '1 T are supported by brackets from the yoke piece 15, and the wheels T T are supported by brackets from the yoke i; so, also, the wheels T T are so pported by brackets from the yokepieces t i respectively, and the yoke-pieces t t are joined together by the equalizer a, and the yokes t i are connected by the equalizer a, and these equalizers are suspended beneath the plate I? by the bolts 3 in. slotted holes in said plate, so that the equalizers can be moved toward or from the cable and carry with them the pairs of wheels aforesaid to press upon the sides of the cable or to release the same.

Around the screws q are the followers 12 n, such followers being threaded to form nuts around the screws, and between the followers and the equalizers a n are springs 5, there being guide-rods passing through the respective portions to keep the springs in place.

Each wheel T T T Tis made with a grooved periphery adapted to tit upon the side of the cable E, and there are, also, cylindrical portions of less diameter above and below the grooved portions, and the yoke-pieces t t t t are adapted to press against the respective cylindrical surfaces, the yoke-pieces being recessed for the reception of the grooved peripheries, and there are loose straps at 7, that prevent the respective rollers T T T T falling away from their proper positions. The straps are connected at their ends to their respective yoke-pieces, and the equalizers a a are pivoted at their ends to the respective yoke-pieces, so that when either shaft r is revolved the screws q will be rotated by the intermediate gearing and move the equalizers u u in either direction, according to the direction of the rotation of the hand-wheel upon the shaft 2'. The construction of the parts is such that the screws q act upon the followers 11 c and bearers a a to bring up the pairs of wheels against the opposite side of the cable and grip the same upon the cylindrical portions of the respective wheels and start the car forward, and then the further movement applies the gripping-blocks s s; or, when the reverse movement takes place, the grip of the blocks 8 s is first liberated, and then the further movement draws back the pairs of rollers T T T T, entirely releasing the hold upon the cable.

This improvement is especially adapted to elevated railways where the cable runs between the tracks, and I am by this improvement enabled to drop the cable, if necessary, or to connect onto the cable after the cable has been raised and placed into the apparatus,
