CHARLES I-IAINES WILLIAMS, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO RAILWAY EQUIPMENT COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
CLASP-BRAKE BEAM.
Application filed July 13, 1916.
To all whom it may concern:
Be it known that I, CHARLES HAINns W'iLLIAMs, a citizen of the United States, residing at the city of Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Clasp- Brake Beams, 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 had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan View of one end of my improved clasp brake beam.
Fig. 2 is a side elevational view.
Fig. 3 is an end view.
Fig. 4: is a plan view of a modified form.
This invention relates to a new and useful improvement in brake beams designed particularly for clasp brakes in that there are two struts or posts, one located at each end for the reception of brake levers or brake applying devices. However, a single strut at the center could be used as in ordinary brake beams.
The object of my present invention is to utilize commercially rolled forms such as I-beams, channels, or the like, or pressed metal sheets for the principal beam member, the ends of said member being swaged down and upset so as to increase the amount of metal at this point and thereby strengthen the beam at and near the point of attachment of the head. In this manner the beam is made strongest at the points of greatest strain.
In the drawings 1 indicates a commercially rolled beam member, here shown as an I- beam, each end of which is swaged down and upset so as to increase the thickness of metal as at 2 so as to form a trunnion 3 having a threaded extension A. This trunnion and threaded extension can be ma- Speeification of Letters Patent.
Patented Aug. 14, 1917.
Serial No. 109,138.
chine finished and, if desired, a case hardened steel or cast wearing ring 5 may be placed on the trunnion so as to provide a wearing surface for the brake head. 6 indicates a strut composed of two members riveted to each other and to the web of the member 1 near the end of the beam. This strut provides means of attachment for the brake applying devices and the opening for the brake lever may be horizontally disposed as shown in Fig. 1, vertically disposed as shown in Fig. A, or angularly disposed, as occasion requires.
In Fig. A I have shown a serrated sleeve 7 on the trunnion by means of which well known adjustable types of brake heads may be used in connection with the beam; also in this figure, the strut 8 is in the form of a casting having a vertically disposed opening for the reception of the brake applying devices.
I claim:
1. A brake beam comprising a commercially rolled flanged member whose ends are swaged and upset to form integral trunnions for the support of the brake heads, the metal of the beam adjacent said trunnions gradually merging into the general contour of the beam.
2. A brake beam comprising a commercially rolled member having struts or posts secured thereto near each end, the ends of the beam beyond said posts being swaged and upset to form mounts for the brake heads, thereby increasing the amount of metal between said mounts and said posts to strengthen the beam at these points.
In testimony whereof I hereunto aifiX my signature in the presence of two witnesses, this seventh day of July, 1916.
CHARLES HAINES WILLIAMS.
