LOUIS P. LAYVRENOE, OF PASSAIO, NEW JERSEY, ASSIGNOR TO THE LAW- RENOE RAILWAY BRAKE COMPANY, OF NEW YORK, N. Y.
CAR-BRAKE.
SPECIFICATION forming part of Letters Patent No. 371,604, dated October 18, 1887.
Application tiled March 24, 1887.
To all whom it may concern.-
Be it known that I, LoUIs P. LAWRENCE, of Passaic, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Railway-Brakes, of
which the following is a specification.
The brake-shoes adjacent to the drivers of locomotives, when applied to the rims of said drivers, bind firmly on the same. It is well known that the drivers of locomotives, especially when running at high speed, have considerable lateral movement, and when the brakes are applied they bind firmly on said driver and prevent this lateral movement,
1 5 causing the drivers to slip,especially on curves, whereby the drivers and their bearings are subjected to undue strain. The brake-shoes are usually fastened on the saddles by means of bolts passed through the saddles and shoes, and
20. as the shoes wear off, the heads of the bolts, which are countersunk in the shoes, also wear oif and said shoes drop from the saddle.
The object of my invention is to hang the Fake-saddles in such a manner that when bound on the drivers they can swing laterallythat is to say, move laterally with the drivers.
A further object of my invention is to secure the brake-shoes on the saddles in such a manner that they cannot drop off, even when said 0 shoes are worn down to a minimum thickness.
The invention consists in a brake-shoe saddle pivoted on the lower end of a link in such a manner that the shoe can swing toward and from the rim of the driver, said link being 5 pivoted at its upper end in an eye formed on the end of a pin mounted to turn in a socket on part of the frame of the locomotive.
The invention further consists in the combination, with the saddle, of a brake-shoe pro- 0 vided with side flanges for embracing the saddle, and akey passed through said flanges and the saddle, all as will be fully described and set forth hereinafter, and pointed out in the claims.
In the accompanying drawings, Figure l is a side view of the saddle, shoe, link, pin, and
socket, and part of the tire of the driver, and
also of the frame of the locomotive. Fig. 2
is an end view of the part shown in Fig. l,
part of the frame being in cross-section. Fig.
3 is a longitudinal sectional view of the socket for receiving the bolt, the cap or eye on the end of the bolt being in section. Fig. 4 is a cross sectional view on line w 00, Fig. 3. Fig. 5 is an enlarged detail horizontal sectional view 5 of the saddle and shoe.
Similar letters of reference indicate corre sponding parts.
The brake-saddle A, which is of the usual construction, is pivoted at its upper end to the lower end of a link, B, in such a manner that the shoe can swing toward and from the tire O of a looomotivedriver. The upper end of the link B is pivoted in a cap or circular casing, D, provided in its bottom with aslot or opening for admitting the upper end of said link, said cap being formed on the front end of a pin, E, mounted to turn axially in a socket, F, projecting from a plate, G, fastened on the frame H of the locomotive. So as to permit said pin E to turn in the socket, but at the same time prevent the withdrawing ofsaid pin, it is provided with a circumferential groove, J, through the lower part of which a key, K, is passed, part of which is located in a transverse groove or box, L, formed on the under side of the socket F. With this construction the brake-shoe can swing toward and from the rim of the wheel, either on the pivot uniting the shoe and link, or the pin E may form the pivot. The saddle and link B can swing laterally on the pivot uniting the cap D and the upper end of the link B. The shoe and saddle are thus capable of following the lateral movements of the driver,even when said shoe is bound on the driver, as it is when the brakes are applied.
The brake-shoe M is provided with two side flanges, N, which embrace the saddle A, and said flanges are each provided with an aperture which can register with apertures in the saddle, so as to permit of passing a key, 0, through the apertures in the flanges and saddle for the purpose of holding the shoe on the saddle. A spring-key can be passed through an aperture, P, in the key 0 for the purpose of holding said key in place. As the shoe is held in place by the flanges and key, the shoe can wear off until it has a minimum thickness without becoming detached from the saddle. Ice
Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. The combination, with a brake-shoe saddle, of a link pivoted to the saddle, a pin pivoted to the upper end of the link, and asocket inwhich the said pin can turn axially, sub stantially as shown and described.
2. The combination, with a brakcsaddle, of a link pivoted to the saddle, a socket, a pin mounted to rotate axially in said socket, and a cap or eye on the outer end of said bolt, in which cap or eye the upper end of the link is pivoted, substantially as shown and described.
3. The combination, with the socket F, of the bolt or pin E, having the circumferential groove J, the key K, passed through part of said groove, the cap D on the outer end of said said flanges and the saddle, substantially as shown and described.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
LOUIS P. LAWRENCE.
