WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 614,628, dated November 22, 1898.

Application filed December 18, 1897. fierial No. 662,387. (No model.)

To all whom it may concern.-

Be it known that I, MARTIN L. SENDERLING, of Jersey City, in the county of Hudson and State of New Jersey, have invented anew and useful Improvement in WVagon-Brakes, of which the following is a specification.

Myinvention relates to an improvement in wagon-brakes in which provision is made for holding the brake-shoe in contact with the wheel-tire throughout the extent of the shoe whatever be the varying positions of the brake-supporting arm under difierent loads.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure l is a view of the brake in side elevation, showing the spindle on the brake-supporting arm in section. Fig. 2 is a top plan view. Fig. 3 is a transverse section longitudinally of the brake-supporting spindle along the line 3 3 of Fig. 2, and Fig. 4 is a View in detail of the brake-regulating spring and its support.

As my present invention is confined to the structure of the brake itself rather than to the brake-supporting arm and means for operating it, I have only shown in connection with the brake the brake-supporting spindle and a short section of the brake-supporting arm.

The brake-supporting arm is denoted by A, and the brake-supporting spindle, extending from the arm A in any well-known or approved manner, is denoted by a. The spindle is here shown as of tapered form, and the brake is supported thereon by a socket-piece B, bearing at one end against a collar 11 and at its opposite end against a washer b, the several parts being held in position by a nut O, screwed onto the end of the spindle. The socket-piece B is in the present instance provided with a shoe D for sustaining the wear due to the grinding contact between it and the tire, the said shoe D being removably secured to the wings of the socket-piece by bolts cl. As thus constructed the brake is at liberty to swing on the spindle ainto such position as may be required to bring its face into a position substantially parallel with the tread of the wheel to which the brake is to be applied.

To hold the brake in an adjusted position where it will be the most effective undernormal conditions and at the same time permit upon lugs 19 b extending from the socketpiece 13 upon opposite sides of the spindle a, as clearly indicated in Fig. 2. It follows that when the collar E is fixed to the spindle the spring F will hold the brake by its engagement with the lugs 11* b yieldingly in position against a rotary movement on the spindle a.

To adjust the brake to the proper tension to do the most effective work requires simply the loosening of the set-screw e and the rota tion of the socket-piece B, which, through the connection of the spring F, will cause the collar E to rotate therewith into such position as to bring the face of the-brake parallel with the face of the wheel,and then fasten the set-screw e to hold the parts normally in the adjusted position. This normal position may be one in which the face of the brake is parallel with the face of the wheel when the wagon is loaded with an ordinary load, in which case if the Wagon-body be spring=supported a lighter load or a heavier load would have a tendency to change the relative directions of the face of the brake and face of the wheel with respect to one another. This, however, would be promptly accounted for whenever the brake was applied to the wheel by the yielding of the spring F at that end of the brake which first engaged the face of the wheel, thereby permitting the entire face of the brake to be brought firmly into contact with the face of the wheel as though in its normal position.

It is obvious that changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein shown and described; but

What I claim is- 1. The combination with a brake-supporting spindle and a brake mounted thereon in free rotary adjustment, the said brake being rotary adjustment, of a collar mounted on the spindle independently of the brake, means for locking the collar in different rotary adjustments on the spindle and a spring carried by the collar and having a bearing upon the brake upon the opposite sides of its axis of rotation, substantially as set forth.
