I 3e it known thatI, Moonr. C; HINTON, a c t zen of the United States, residing at Hinton, in the county of Summers and State of West. Virginia, have invented new and useful Improvements in CarrBra-kes, of

My ;i nvention.re ates to'certain new and useful mprovements in car brakes and cons:1sts in the novel'combmatlon and arrangeparticularly described and pointed out in the claims. 1 g :'In the drawings: Figure'l isa front elevation of my complete invention. Fig. 2 isa detail View showing the train pipe and valve connections formin apart thereof and secured-to the usual Frame of the car. Fi 3 is a vertical longitudinal -section (alien through .the train pipe and valve forming a part thereof and constructed accordin to my invention taken on the line w-w of Fig 2. Fig. 4 is a transverse section taken on in connection with the draft timbers o the car and used in connection with a valve lever;

.a very simple, practical and effective up aratusfor automatically causing the bra 'es to be operated or set on a car or train, should the brake beam or other rigging placed, inoperative or dropped to assume a of t 'e car or train.

' The invention therefore consists of a chain or other yielding connection attached tothe arch or brake beam, and in a movable and operative connection with'the suitable valve located in the train pipe, whereby the accidental displacement of the brake beam or rigging forming apart of the latan escape of air 1n the train pipe and simultaneously setting tire train to which m invention is applied. Referring to the rawings, 1 represents an ordinary car having the usual wheels 2, shaft or axle 3 and 'boxes 4, all of which is of the ordinary construction. The brake beam 5 is also of the usual conva ve casing nature of m automatically set the bra slotted, through whi struction' and is suspended from the draft rigging of the car in the usual and wellknown manner and is provided with the ordinary brake shoes.

Passing through the brake beam 5and secured thereto 1n any suitable mechanical manner are eye-bolts 6 to which are secured the .op osite free ends of the chain -7, the

latter eing adjustable along its length by turn-buckles 8, the uniting endsof said chain terminating ata common center and being attached to the free end of the lever 9, all of which Willbehereinafter more fully described. By referring particularly to Figs. land 2 of the drawings, it will be seen that the train pipe 10 is of the -usual construction :and in carrying out my invention the same is rovided along its length or below the b0 y of the car with a tubular extension 11 within which is located a valve plug 12 having a longitudinal port 13 in communication with the train pipe and a horizontal rt 14, the outer end of which is ada t to re ister with the opening 15 forme in the 16. a i I The valve plug 12 may be of anysuitable design or construction and to the outer projectmgend'of which is secured a lever 17 to the free end of which is secured the opposite connecting ends of the chain 7 leading from the brake beam 5 of the brake ri in l do not limit myself to the precise 0011'- struction of the valveherein shown and.

described, as the same may be modified in.

many respects without departing from the invention and referring particularly to 3 of the drawings it will be seen that threaded cap 18 to close the upper projecting tubular extension 19 forming a part of sald valve, the principal object, as before'stated,

being to cause an escape of air in the train pipe should there be any accidental dishave employed ascrew lar bar also having a slot 23 for freely receivmg the lever 9 when the latter is oper- "ated in its downward movement.

From the foregoing description it will be seen that when the brake beam 5 is in its normal or operative position in respect to the wheels of the car the valve will be in a closed position to prevent any escape of air from the train pipe, but should the said brake beam drop or become displaced from its normal or proper position, the said valve will be automatically operated causing the port in said valve to register or communicate with the opening 15 of the valve casing,

- thereby allowing an escape from the train pipe and causing the brake of the particular car or train to be automatically set, all

of which is of the usual and Well-known construction.

Having thus described the invention what is claimed as new is:

1. A. car brake comprising a suitable valve in communication within the train pipe, and suitable means connected with said valve and with the brake beam of a car, as i v and for the purpose described. I

2. A car brake comprr'ng a sultable valve communicating with and forming a part of the train pipe, and suitable means 1 attached to said valve and also to the brake i beam of a car, whereby when. said brake i beam is accidentally displaced the said valve is automatically operat'edfor permitting an escape of air from the train pipe, as and for i i the purpose described.

3. A" car brake comprising a suitable valve having a longitudinal and transverse port formed therein and adapted to register .1

k thereof for the escape of air, a chain having i its opposite end attachedto the brake beam 5 of a car and removably connected to a suit- '1 able lever forming a part' of said valve for operating the latter, an angular plate one in presence of two witnesses.
