Application filed March is, 1921.

To all to 710m it may concern:

Be it known that we, LoREN L. WHITNEY and TVILLIAM C. HnDGoocK, citizens of the United States, residing, respectively, at Hammond, in the county of Lake and State of Indiana, and at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Brake-Beam Fulcrums, of which the following is a specification.

This invention relates to brake beam fulcrums.

One object of the invention is to provide a simple and eflicient forged brake beam fulcrum in which the body portion enclosing the lever is securely connected by an integral bridge and at the same time permits of the application of a separable suspension attachment and of a separable tension rod seat which can be easily made in a separate piece and which is not required to be rightor left-hand for rightand left-hand fulcrums, the same seat being applicable to either rightor left-hand fulcrums.

Another object is to provide a simple and improved forged brake beam fulcrum adapted to meet the various requirements for successful commercial use.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in which Figure 1 is a top plan View of a forged fulcrum embodying our invention;

Figure 2 is a side elevation of same; and,

Figure 3 is an end view of the same fulcrum.

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

Referring to the figures of the drawings, it will be noted that the body portion of the fulcrum includes two parallel arms 10 and 11 connected at their front ends by an integrally formed bridge 12. These spaced arms 10 and 11 are provided with aligned perforations 13 and 14 for the reception oi a pivot pin to which is connected the usual brake lever, not shown, but which is located between said arms. The arms 10 and 11 terminate rearwardly in two offset ortions 15 and $16, which may be secured to Serial No. 453,326.

the compression member of a brake beam in an; suitable manner.

The seat member 17 is formed of a sepa rate iece and is provided with a seat 18 for the reception of the tension rod of the brake beam. Extending rearwardly from the body of the seat member 1'? is a shank 19 which extends through an opening 20 in the bridge 12 of the main body portion and which is riveted to form a head 21 for securing the tension rod seat member to the main body of the fulcrum. By forming the tension rod seat in a member separate from the main body of the fulcrum, the necessity of mating rightand left-hand seats is obviated, for it is apparent that these seat members may be applied to fulcrums arranged for rightand left-hand use. This greatly simplifies and reduces the number of dies required for producing the fulcrum seat.

A suspension attachment is provided for this fulcrum and it is in the form of a separate piece 22 shaped to provide a suitable receiving portion 23 for a suspension hanger and provided with a hole 24 through which the shank 19 of the tension rod seat extends for securely holding the suspension attachment 22 in position between. the bridge 12 of the main portion of the fulcrum and tDG seat member 1'? thereof. It will be un- -rstood that when the shank 19 is passed trough the openings 2": and 20, the shank s in a heated condition and the other parts *elatively cool, whereupon the parts in question are riveted together.

It is our intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

We claim:

(ill

1.. A forged. fulcrum comprising a plurality of separate'members including a lever receivingmember, a tension rod receiving member, and a suspension attachment memher, one of said members having a shank by means of which. all of said members are connected together,

2. A forged fulcrum comprising a plurality of separate members including a lever receiving member, a tension rod re-- ceiving member, and a suspension attachment member, said tension rod receiving member having a shank passing through openings in said lever receiving member and said suspension attachment member whereby all of said members are fixedly connected together.

3. A forged fulcrum comprising three separate members including a lever receiving member a tension rod receiving member, and a suspension attachment member,

the latter being secured between said other two members. 10
