UNITED STATES PATENT O FICE.
PHILIP v. OONOVER, or UVALDE,TEXAS.
ELECTRIC CAR-BRAKE.
I SPECIFICATION forming part of Letters Patent No. 224,880, dated February 24, 1880.
l Appli ation filed December 3, 1879 To all whom it may concern:
Be it known that I, PHILIP VORUS OoNo- VER, of .Uvalde, in the county of Uvalde and State of Texas, have invented a new and Improved Electric Oar-Brake, of which the following is a specification.
The object of my invention is to provide a new and improved car-brake, which is actuated by the rotation of the car-wheels and is governed and regulated by electricity.
The inventionconsists in a car-brake form ed of a pinion attached to the car-axle, the pinion taking in a ratchet-wheel provided with a v I projectingpin, that enters into the slots of a brake-chain is wound, which sleeve can be wheel provided with a sleeve, upon which the l moved on the axle by means of a lever that is w actuated by a rod passing into a helix connected with a battery on the locomotive. A pawl-tooth that is held in place by a slide In the accompanying drawings, Figure 1. is a plan view of the under side of the car. Fig;
1 2 is a vertical longitudinal sectional elevation of the same on the line m 00, Fig. 1. Fig. 3 is a vertical cross-seotional elevation on line y y,
Fig. l.
Similarletters of reference indicate correi sponding parts.
The pinion A isfastened to the car-axle B,
l I and takes in the ratchet-wheel C, provided with a pin, D, curved beveled projections E E, andmounted on the shaft F, supported in the two bearings G and G,-fastened to the under side of the car floor H. A ratchetwheel, I, provided with curved slots '5 i, into which the pin D passes, and a sleeve, J, upon "which the brake-chain is wound, is loosely 'mounted on the shaft F. A lever, K, is loosely attached to the shaft F adjoining the sleeve,
and the upper end of the lever is attached to a, to the under side of the car-floor.
rodlL, which passes into a helix, M, fastened The lever rests against the shoulder g in the bearin g G,
i i and is thus fulcrumedt A slide, N, provided with a vertical flange, O, is suspended from a beveled cross-bar, P. The slide N has a beveled groove in its upper edge, into which the slide Q fits. Q is fastened to the lever B, fulcruined at S, and attached to the rod T, pass ing into thehelix U. The slide is also provided with a slot, V, through which a slotted camtooth, W, provided with a head, 2, passes. The helices are connected with a battery on the locomotive.
The operation is as follows: As the pinion A is attached to the axle B it will revolve with it when the train moves forward in the direction of the arrow to, and A will cause the ratchet-wheel O, in which its teeth take, to rotate in the direction of the arrow 0. When the circuit of the wires connected with the helix M is closed, the end of the lever Kis drawn in the direction of d and the wheel I is pressed against 0, the pin D enters one of the curved slots 41 i in I, and the wheel I, with the sleeve J, rotates with 0. As the brake-chain is fastened to the staple j, the chain will be wound up tight on the sleeve J by the rotation of the same, and the brakeshoes will be pressed to other wheels of the car with considerable force. As the wheel 0 rotates, the beveled projections E E gradually press the vertical flange O in the direction of e, and this flange presses the wheel I away from C, so that the pin D no longer takes in the slots 2' i. The pawl-tooth W rests in the teeth of I and prevents the brake-chain from unwinding.
If it is desired to further slacken the speed of the train, the current is again closed, and
the above operation repeats itself until the train is stopped, the pawl-tooth Wpermitting I to turn in the direction of 0, but preventing a movement in the opposite direction. During all this time the head 2 of the pawl-tooth W was firmly clamped between the top of N and the slide Q.
If it is desired to loosen the brakes, the circuit passing through the wires connected with the helix U is closed, and the rod T will be drawn. in the direction of f, the slide Q will move back from the head of the pawl-tooth W, and the same can give way to the pressure of I, and the brake-chain is unwound. The pawl-tooth W is slotted and held by a pin, p, and operates equally efficiently for all movements of the train.
The levers K and R are connected by the rod Z, so that when one operates it always sets the other in position for operation.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a oar-brake, the combination of the ear-axle B with the pinion A, the ratchet-wheel 0, provided with a pin, D, the wheel I, provided with a sleeve, J, and the lever K, actu ated by a rod, L, passing into a helix, M, substantially as herein shown and described, and for the purpose set forth.
2. The combination of the wheel 0, provided with slanting projections E E and pin D, with the wheel I, having slots 6 i, and with the I 5 flange O and the pawl-tooth W, substantially as herein shown and described, and for the purpose set forth.
3. The combination of the pawl-tooth W with the slides N and Q, the lever B, the rod 20 'I, and the helix M, substantially as herein shown and described, and for the purpose set forth.
PHILIP VORUS OONOVEE.
