CAR BRAKE AND COUPLING.

.QPECIPICATION forming part of Letters Patent No. 308,695, dated December 2. 188%.

Application filed May 5, 1884. (No model.)

To all whom it may concern.-

Be it known that I, HOWARD L. PEGRAM, of Summerset, in the county of Warren and State of Iowa, have invented a Gar-Coupling and Railway-Brake, of which the following is a specification.

My invention consists in the construction and combination of a draw-head, a tubular coupling-link, shaft-sections having clutches on their ends, a clutch-guide, and brake-operating mechanism,as hereinafter fully set forth, in such a manner that the coupling of cars and coupling of a shaft for operating the brakes will be automatically accomplished at the same instant, so that all the brakes on all the cars in a train can be simultaneously operated by means of power applied from the engine or by a person on the engine, and also independently operated upon any car when detached from the train.

Figure 1 of my accompanying drawings is a transverse section, Fig. 2 a top view, and Fig. 3 a side'view, of my draw-head. Fig. 4. is a longitudinal vertical section of my drawhead, coupling-link, shaft and clutch, clutchguiding device, and brake-operating mechanism combined with a section of a car. Fig. 5 represents the end of the continuous shaft for operating the brakes on a train of cars. Fig. 6

is a section of an inverted car, showing the brakeshaft combined with the brake-lever. Fig. 7 shows the position of the gearing when the brake force is relaxed. position of the same gearing when the brake force is applied.

Jointly considered, these figures clearly illustrate the construction, application, and operation of my complete invention.

A reprcsentsla car.

B is my draw-head. It has a flaring mouth, and a large cavity that is open at the top and extends to the rear end.

0 C are draw-bars formed on or fixed to the opposite sides and rear end of the head. They are attached to the car in a common way, and have collars and springs applied in the manner car-buffers are usually formed.

A is an upward extension on the front end of the draw-head adapted to receive a common link and pin, as indicated by dotted lines in Fig. 4:.

B is a hook hinged in the rear end of the Fig. 8 shows the cavity of the draw-head, and extends forward to the extension A D is a frame fixed on top of the draw-head in such a manner that the hook B can move vertically within the frame.

D is a spring fixed to the frame in such a manner that it will, in its normal condition, press .the hook down into the cavity.

F is a tubular coupling-link that has conical heads F adapted to enter the mouth of the draw-head to engage and lift the hook B", which hook will descend and engage the head, as clearly shown in Fig. 4., and as required to couple two cars together.

G is a shaft suspended under each car by means of hangers or shaft-bearers Gfithat are fixed to the bottom of the car by means of screw-bolts, or in any suit-able way.

G represents a clutch device on the end of the shaft.

H is a shaft-section that extendsthrough the tubular link F, and that has counterpart clutch devices to engage the clutches G on the ends of shafts G.

J is a cup-shaped clutch-guide, fixed to the end of the shaft G, to inclose the clutch G in such a manner that when the head F of the couplingli'nk enters the draw-head it will also enter the open end of the guide J, to be thereby brought into a concentric position with the shaft G as required to guide the clutch on the end of the shaft-section H into contact with the clutch G 011 the end of the shaft G, to thereby produce a continuous rotating shaft under two or more cars that may be coupled together by means of my invention.

K is a gear-wheel fixed to the shaft G.

L is a toothed sector fixed to a shaft, M,that has its hearings in the hangers G". This sector engages the wheel K, and has an arm, N, ex tending downward, as shown in Fig. 7.

P is a clevis pivoted to the end of the arm N.

R is a chain fixed to the end of the clevis to extend over a directing-pulley to be connected with the end of a rod, S, that is attached to the long arm of a brake-lever, 'I, as clearly shown in Fig. 6. \Vhen the shaft G is rotated to the right or left,the gear-wheel K will actuate the sector L and its arm N as required to transmit power to the brake-lever 'I through the chain R and rod S.

Power may be applied from the engine by means of gearing connected with a wheel on the end of the continuous shaft G in such a manner that all the brakes in a train of cars will be operated simultaneously.

U represents a ratchet-wheel, and V a brakelever fixed to the shaft G in such a manner that the shaft G can be thereby rotated to apply the brakes by a person on the platform of a car or at ;the end ofthe car by simply pulling the lever to rotate the ratchet-wheel by means of. a pawl in a common way.

Z represents a rod connected with the coupling-hook B in such a manner that a person on the car can readily uneouple by simply applying a lifting force to the rod.

I claim as my invention 1. The draw -hcad 13, having an opening extending through and a gravitating hook,B', pivoted in the opening, the draw-bars O O, a rotating rod, G, having a clutch device on its end,a tubular coupling-link, F F, and a shaftsection, H, arranged and combined to operate in the manner set fortlnfor the purposes specified.

2. The guide J, in combination with the shaft G, having a clutch device, G, for the purposes specified.

3. The shaft G, having a fixed gear-wheel, K, the sector L, having an arm, N the clevis P, and a chain, in combination with a brakelever on a car or truck,to operate in the man ner set forth, for the purposes specified.

4. A car-coupling and -ear-brake combined, consisting of a draw-head having a gravitating hook, a tubular coupling-link having tapering heads, a rotating shaft having clutch devices on its ends, a shaft section having clutch devices on its ends extended through the tubular coupling-link, a gear-wheel fixed 'to the shaft, a sector having an arm flexibly connected with a brake-lever, substantially as described, to operate in the manner set forth.
