IBRAKE-BEAlVI-FULCR-UM CONNECTION.

Specification of Letters 1?atent. Patented Dec. 2, 1919.

Application filed July 27, 1917. Serial No. 183,048.

To all whom it may concern Be it known that 1, WILLIAM C. HEDG- COCK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Brake-Beam- Fulcrum Connection, of which the following is a specification.

This invention relates to brake riggings, and more particularly to connecting means between the lever fulcrums and their associated parts. 7 7

One of the objects of my invention is to make connections between lever fulcrums and their associated parts more durable.

Another object is to provide an improved connection between the parts in question to meet the various requirements for successful commercial operation.

These and other objects are accomplished by providing a lever fulcrum having an opening therein, an associated member having an opening therein, a pin extending through the openings in said lever fulcrum and member connecting the same, and means to prevent movement of said pin.

The invention is illustrated on the accompanying sheet of drawings, in which Figure 1 is a plan View of a brake beam having secured thereto lever fulcrums embodying my improved connecting means between the lever fulcrums. and associated parts;

Fig. 2 is a fragmentary side elevation, parts being in section, showingon a larger scale my improved connection between a lever fulcrum and a lever; and

Fig. 3 is a fragmentary top elevation of the arrangement shown in Fig. 2.

The various novel features of my invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claim.

Referring to the figures of the drawing, it will be noted that I have shown a brake beam having trunnions 11 at opposite ends thereof for the reception of brake heads (not shown). Secured to this brake beam,

which as shown is of I-section, near opposite ends thereof, are lever fulcrums 12 and 13, and secured to the middle portion of said beam is another fulcrum member 1 1. The free end of each of the fulcrum members is bifurcated to form jaws 15 and 16 which are for locking each pin in two places.

provided with registering openings 17 and.

18 respectively.

As shown in the figures of the drawing, a

lever 19 is pivotally connected to each of the fulcrum members 12 and 13 by a pin 20 which passes through the openings 17 and 18 in the jaws of the fulcrummember and also through an opening: 21 in the associated brake lever.

also extending through an opening 27 in the pin 20, whereby the pin 20, which forms the pivotal connection between the fulcrum lever and its associated member, may be held in a given position. I have provided each of the bosses with registering openingsfor the reason that the pin may be driven in from" either side. If desired, the pin may beprovided with a plurality of openings, one adj cent each of the pairs of slots in the bosses The pins shown in these drawings are provided with heads 28, but it is evident that plain pins may be provided if desired.

Pivoted to the middle fulcrum member 1 1 is any suitable member 29, for example, a hanger or a pull rod. The pivotal connection of'this member to the fulcrum member is the same as the pivotal connection between the lever fulcrum 12 and 13 and their cooperating levers 19, the pin being 7 locked against movement.

By means of this arrangement the life of the pin connecting .the parts in question is greatly lengthened and at the, same time requires a minimum amount of attention.

It is apparent that there may be various modifications of the invention herein particularly shown and described, and it is my intention to cover all such modification which do not involve a departure from the spirit and scope of the invention as set forth in the following claim.

Heretofore the pin has been permitted to move around freely in thel-Vhet I claim is: r In brake mechanism, the combination of a lever fulcrum, one end of which is provided with jaws having bosses With registering openings and also open slots therein, abrake member associated therewith located be-v tween the jaws and having an opening registemng With the openings 1n sald bosses n p111 WhlCh may" be passed through said 0pen ings from opposite directions, and akey connected to said pin and insertible in either one of said slots in accordance with the position of the in to prevent movement of the latter.

' Signed at Chicago, Illinois, this 18th day of July, A. D. 1917.

WILLIAM G. HEDGCOCK.
