CABLE-HAULED CAR.

Specification of Letters Patent.

Application filed May 13, 1912.

Patented Feb. 18,1913.

Serial No. 696,979.

To all whom it may concern:

Be it known that I, PAUL Bns'rA, a subject of the King of Prussia,residing at Ratingcn, in the Kingdom of Prussia, Germany, have invented certain new and useful Improve ments in Cable-I-Iauled Cars, of which the following is a specification.

This invention relates to a braking device for cars hauled by cables or by chains. The braking device operates automatically as soon as the car is released from the cable or chain.

According to this invention the braking device consists of brake-blocks which are antomatically placed upon the rails in front of the wheels by the releasing device as soon as the car is released from the cable or chain. The wheels run up the brake blocks whereby the car is immediately stopped. The lower surfaces of the brake blocks which are pressed by the wheels upon the rails are roughened whereby a better braking action is insured.

In the accompanying drawings the invention is shown by way of example Figure 1 shows in front elevation a tipping car having the improved braking de' vice; the brake-blocks are shown in lifted position. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a side elevation, the brake blocks being shown in the braking position. Fig. 4 is a detail view showing the roughened surface of the brake-blocks.

The continuous cable or chain Z is placed in a gripper fork a carried by the car. This gripper fork a is loosely mounted in a hearing 6 fixed upon the front wall of the car. A rope or chain c is fixed to the shaft of the gripper fork a so that it winds around said shaft when the gripper fork is being turned. This chain has two branches (Z and e of which the one (Z is guided in guide pieces f, the other one being guided over grooved disks 9 and through guide pieces h. The brake blocks 2' are fixed at the ends of the branches (Z and e of the rope or chain. The

brake blocks are mounted upon angular cross rails and present extensions 70 designed to grip over the heads of the rails (Figs'l and 3) whereby they are securely brought into the proper position between the rails and the wheels when they are released (Fig. 3).

Before the cable Z is placed into the gripper fork a this fork is turned so that the chain 6 is wound around its shaft whereby the brake blocks 2' are lifted off the rails m. If the car for any reason whatsoever is disconnected from the cable Z the fork a, which is thus released, turns back under the tension of the ropes or chains (cde) so that the chain c unwinds from the shaft of the fork and the brake-blocks which are thus released drop upon the rails immediately in front of the wheels. The car runs upon the blocks 70 whereby it is stopped. The lower surfaces of the brakeblocks are roughened whereby a better adherence upon the rails is insured. Theweightof the chains (0de) which connect the brake-blocks with the gripper fork could be increased by the addition of weights.

If the car has to move only along one incline, the brake-blocks need be arranged only at one side of the wheels but the releasing device remains the same as her'einbefore clescribed.

If the car is moved by hand the brake fork is looked after the chain c has been wound around the shaft of the fork and the brake-blocks 7c have been lifted off the rails; V

for this purpose a cotter n is inserted in alining openings in the gripper fork and its bearing (Fig. 1).

1. An automatic braking device for cable hauled ears comprising in combination brake-blocks, suspended in front of the wheels, chains to which said brake-blocks are attached, a bearing fixed on the front wall of the car, a gripper fork loosely mounted in said bearing, and the chain of the brake blocks fixed to said fork so that it can be wound around the fork shaft to lift the brake blocks off the rails, substantially as described and shown and for the purpose set forth.

2. An automatic braking device for cable hauled cars comprising in combination brake-blocks, suspended in front of the wheels, chains to which said brake-blocks are attached, a bearing fixed on the front wall of the car, a gripper fork loosely mounted in said bearing, and the chain of the brake-blocks fixed to said fork so that it can be wound around the fork shaft. to lift the brake-blocks off the rails, and means for locking the gripper fork after the chain has been wound up, substantially as described and shown and for the purpose set forth.
