EDIVIN N. LUOE, OF BRADFORD, PENNSYLVANIA.

SAFETY CAR-BRAKE.

SPECIFICATION-forming part of Letters Patent No. 425,443, dated April 15, 1890.

Application filed August 6, 1888! Serial No. 319,936. (No model.)

To all whom it may concern:

Be it known that I, EDWIN W. LUOE, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Safety OarBrakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specifica" tion.

My invention is in the nature of a safetybrake which will automatically be put down against the wheels in the event of the cars of a train breaking apart.

It has for its object to simplify and cheapen such devices and to render them certain and prompt in action.

With these objects in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter described, and afterward specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a view, partly in section and partly in elevation, of so much of two adjoining cars of a train as is necessary to illustrate my invention. Figs. 2 and 3 are detail views.

Like letters of reference mark the same parts in all the figures.

Referring to the drawings by letters of reference, A is the body, B B the wheels, and G the bumper, of a car.

D is the bumper, and E the body, of the next adjoining car to be coupled thereto by means of any preferred coupler.

F, G, and H are the bars which form, with the other necessary and well-known parts, an ordinary brake mechanism, the construction being such that a pull upon a chain-rod I, attached to a lever H at It, will cause the four brake-shoes of the truck to be forced against the wheels, such brake-shoes being normally held away from the wheels in a well-known manner by their springsuspended bars J in a manner common to brake mechanism.

Attached to the bottom of the end of the car, preferably to the end sill K, is a box. L,

in this instance shown as of a U shape, within which is pivoted at Z an arm M, having its outer ends formed into a hook m. The rod I before mentioned is attached to this arm M between its pivot and the hook m through the medium of a'laterally-projecting pin N, which passes through a curved slot 0 in the side of the box L. A link or hook Pis attached by a chain p or other suitable means to any available part of the adjoining car, preferably the end cross-beam.

The operation of my invention may be described as follows: The cars being coupled together and the hooked arm M m being in the position shown in full lines, the link P of the adjoining car is passed over the hook on.

Should the cars accidentally part by breaking of the coupling or otherwise, the link P willpull the arm M down to the position shown in dotted lines in Fig. 2, when the pin N will rest at the bottom of the slot 0 and the rod I will be in a line that will bring it below the pivot Z of arm M, whereby it will lock the parts in position, preventing the arm from rising, and by this drawing down of the arm M the brake-shoe will be brought into contact with the wheels. As soon as this lower position of the arm M is reached the link P will slip off the hook m, thus preventing breakage of any of the parts. The brakes will remain on until the arm M is released from its locked position, which can be done by hand or in any preferred manner, it being only necessary to raise it until the rod I passes above the pivot Z, when the pull of the brakes on the said rod will draw it up and retain it in its raised position.

It will be understood that this mechanism may be applied to both'ends of all the cars.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. In combination, a car, its braking mechanism, a trip-arm pivoted to the car and connected to the braking mechanism, and a link or loop attached to the next car for engaging said trip-arm, substantially as and for the purposes set forth.

2. The combination, with the brake mechanism of a car, of a pivoted trip-arm having a hooked end, a rod connecting the brake mechanism to said arm between its pivot and in said box at Z and having hook m, the pin hook, and a link or hook attached to the next N, projecting through said slot, the chain or car to engage the hook of the trip-arm, as set rod I, attached to said pin N, and the brake forth. mechanism, all substantially as set forth I 5 5 3. In combination, the brake mechanism, In testimonywhereofI affix mysignatnre in this1 arm M, pivoted at Z and hook m, and the presence of two witnesses.

r0 or chain I, connecting the brake mechanism to the arm at a point between the pivotl EDWIN LUOE' and hook on, as set forth. Witnesses:

1o 4. In combination, the box L, having curved ORLANDO LU CE,

slot 0 in the side thereof, the arm M, pivoted JOHN HAGGERTY.
