The, object of my invention is toprovide -a lsaf'eLand/convenient means totrav erse, de-' scend or to hold ma stat onary position on cable, W1re lme or'hemp rope.

3 5' A further ob]ect 1s to prov de a' movable seat; equipped with both effective hand and foot brakes, that cablecar may be stopped and held inany location on line regardless of the angle'of the cable,lwire line o-rhemp rope. .10 A still further objectiof my invention is to providean anti-friction brake actionthat Willnotcutor destroy in any way the carrier line stopping or holding the .car in a fixed position. Another object of my invention is to provideproper housing for "all the working .parts, therebyprotecting it from the weather.

@Furthen-it is. an object of the invention to- "provide asafety device for'the derrick man 1120 on an oil rig so as to-enable him todescend to out or catches on fire.

the. ground insafety in casetheywellblows Another object of my inventlon is equip ping a car with a foot brake iinaddition to a 2 ,2 hand brake, that hastwice the. leverage .of the handbrake, thus enabling the operator freedom of both hands When desired, the .foot and hand brakes being so associated and combined that both may be applied once if desired as man emergencyivvhere alquick stop is to 'bemade or where'the inclineof the cable isparticularly great. i 1

' ther objects will in partbeobvious and in part be pointed out hereinafter.

To the attainment of the aforesaid .objects andends, my invention consists in the novel details of construct on and in the comblna tion, connection and arrangement of parts, hereinafter more .fully described 'and then pointed out in the claims. --Y In the drawing:. 7 t Figure 1 i }'a side elevationiof my invention in use.

the ends 2 and' 3 of which are carried the shafts 4 and 5 respectively for the grooved Wheels 6 that ride on the cable 26 and .susr pend the car. p t

Suspended from the shafts land ,5 ,respectively arethe rearhanger barsi8- and the front hangerbars 7, these bars having 7 aMountedbetween the side bars 1 -1 on shafts 12 are friction rollers 11-, theybeing spaced .apart a sufficient distance to permit placement and operationoflthe brake levers. The rollers 11. are so positioned as .to ride 7,? iii-contact with the topofthe cable'26. I Mounted on pivots 14 and 19, respectively are brake levers 13 and 18 respectively,;th ese levers having their pivoted .ends bifurcated (to permit passage of-the cable 26 and carry, so

the-personzcan. place his feetonthebar 23 and his. hands .on'athe levers 'l'l. v Thenzby simul- ;.tanenouslyj;pushing with his feetmad pulling with -hisihands he is enabled 1 to apply both brake devices simultaneously; The pushing ,00

' 190 -It willfalso benoted that .the brake ,devices U "are arranged adjacent the forwardendpofthe carriage soasz toleave suflicient room at the with the feet and pulling with the hands enables the one action to, in effect, brace the other action so that through the cooperation of the push and pull actions the full braking power is applied.

In order to protect the braking devices, the side bars 1 may support a cover 27 which also serves as a water shed to prevent the elements reaching the bearings of the wheels 11 and brake levers l3 and 18.

By adjusting the platform 24: up or. down it can be made to lie level regardless of the angle of the cable 26 to the horizontal. In

other words, if the cable 26 is inclined to a' points somewhat within the distance between the shafts or axles 12 so that there will be a slight tendency to kink the cable 26 which effectively aids in reducing the speed of the car or stopping it as may be desired.

From the foregoing description, taken in connection with the accompanying drawing, it is thought the complete construction, operation and advantages of my invention will be clear to those skilled in the art to which it relates.

What I claim is:

1. In cable cars, a pair of grooved wheels to ride on a cable, side bars, shaft members carried by said side bars at the front and back on which shaft members said. wheels are mounted, a platform suspended from. said shaft members, associated hand and foot brakes mounted on said side bars to operate on the cable, said hand and foot brakes being located adjacent one another and adapted for simultaneous use.

2. In cable cars, a pair of grooved wheels to ride on a cable, side bars, shaftmembers carried by said side bars at the front and back on which shaft members said wheels are mounted, a platform suspended from said shaft members, a brake comprisinga fixed roller carried by the side bars over the cable and a swinging yoke mounted pendently fromsaid side bars and through which the cable passes and having rollers beneath thev cable to engage the cable and press it against the fixed roller for the purposes specified 3. In cable cars, a pair of grooved wheels to ride on a cable, side bars, shaft members carried by said side bars at the front and back on which shaft members said wheels are mounted, a platform suspended from said shaft members, associated hand and foot brakes mounted on said side bars to operate on the cable, said hand and foot brakes being located adjacent one another and adapted for simultaneous use, and a cover carried by said side bars.

4:. In cable cars, a front and back grooved wheel to run on a cable, members in which said wheels are mounted and which members space said wheels apart, said wheels having shafts,'front and back hanger bars pendent from said shafts, a platform adjustably supported by said hangerbars whereby the platform may be level regardless of the inclination of the cable.

5. In cable cars, a front and back grooved wheel to run on a cable, members in which said wheels are mounted and which members space said wheels apart, said wheels having shafts, front and back hanger bars pendent from said shafts, a platform adjustably sup.- ported by said hanger bars whereby the platform may be level regardless of the inclinationof the cable, two fixedly located rollers mounted on said members, ftwo brake levers pendently mounted on said members between said fixedly located brake rollers and themselves having brake rollers, thecable passing below said fixed brake rollers and above said brake levers rollers, all being arranged whereby a person on said platform may simultaneously push one of saidbrake levers and pull the other, thereby applying the brakes. c

6. In cable cars, a front and back grooved wheel to run on a cable, members in which said wheels are mounted. and which members space said wheels apart, saidzwheels having shafts, front and back hangerbars pendent from said shafts, a platform adjustably supported by said hanger bars whereby the platform maybe level regardless of the inclination of the cable, and a water shed carried by said members, and brace rods connecting said members with one pair of said hanger bars.
