BRAKE-BEAM SUPPORT.
inc-6,915.
Specification of Letters Patent. Patented Feb. 14, 1922.
Application filed February 9, 1920. Serial No. 357,227.
To all whom it may concern:
Be it known that I CHAIzLns Hninns VIL- LIAMs, a citizen of theUnited States, residing at Chicago, Cook County, Illinois, have invented a certain new anduseful Improvement in Brake-Beam Supports, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accom panying drawings, forming part of this specification, in which.-
Figure 1 is a side elevational view of my improved brake beam support.
Figure 2 is an end elevational view partly in section of the form shown in Figure 1;
Figure 3 is a sectional view of a modified form.
This invention relates to a new and useful improvement in brake beam supports, known commercially as third or fourth point supports, which are used in connection with brake beams to ride upon track plates to guide the beams when power is applied thereto in the application of the brakes. It sometimes occurs that the rubbing surface of the third or fourth point support wears away thereby necessitating the renewal of the entire chair.
It is the purpose of the present invention to provide the chair with a detachable wearing surface which may be of the same metal as the chair or of hardened metai.
While I have illustrated my invention as adapted particularly as a third point support (Figs. 1 and 2), it is obvious that the same can be used as a fourth point support as shown Figure 3, both the third point supports and the fourth point supports being well known in the art and being illustrated in prior patents to me.
In Figures 1 and 2, 1 indicates the chair which is pivotally mounted on the ends of the strut in a well known manner, said chair being provided with a recessed lower portion in its lower facein which is arranged a removable and renewable wearing surface or shoe 2 held in position by a cotter pin 3,
said pin passing through the sidewalls of the chair and through an opening in an upwardly extending lug 2 which is received by a pocket or recess within the side walls of the chair.
In Figure 3, I have shown a fourth point support in which there is a clamping member for attaching the chair to the tension member of the brake beam, said chair (as indicated at 5 in Figure 3) having a recessed lower face in which is arranged a rubbing surface 6 held in position by a rivet 8 passing through a projection or lug 6 extending up into a pocket formed in the lower recessed face of the chair. The upwardly extending arms of the chair are designed to be clamped together by a fastening means so as to secure the chair to the tension mem ber of the beam. By providing a recessed face in the bottom of the chair, an extended surface is provided for the renewable wear surface whose edges (in Figure 3) or shoulders (Figures 1 and 2) are preferably confined within the downwardly extending ma1= ginal flanges of the chair, and in this way strain is taken from the cotter pin and the wear surface lug through which it passes.
hat I claim is:
1. A chair for third or fourth point brake beam supports-having a recess or pocket in its lower face, a renewable wear-surface ar ranged on the underside of said chair, a proection or lug extending upwardly from said wear surrace and into said recess or pocket, and means co-operating with maid lug to hold said wear-surface in position.
2. A chair for third or fourth point brake beam supports having shoulders forming a lower face, a wear-surface having shoulders for engagement with the shoulders of the chair which form said recessed lower face, a lug extending upwardly from the wearsurface and into a pocket in said chair, and a removable fastening means engaging said lug to hold said wear-surfacein position.
In testimony whereof I hereunto aiiix my signature this 6th. day of February, 1920.
CHARLES HAINES WVIL IAMS.
