PHILIP B. HARRISON, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO RAILWAY EQUIP- I MEN'I COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
THIRD-POINT SUPPORT FOR BRAKE-BEAMS.
Specification of Letters Patent.
Patented June 6, 1916.
Application filed March 20, 1916. Serial No. 85,334.
T all whom it may concern Be it known that I, PHILIP B. HARRISON, a citizen of the United States, residing at Chicago, Illinois, have invented a certain new and useful Improvement in Third- Point Supports for 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 side elevational view partly in section of one form of my improved third point support for brake beams. Fig. 2 is an enlarged detail of the form shown in Fig. 1. Fig. 3 is a modified form, and Figs. at and 5 are other modified forms.
This invention relates to a new and useful improvement in third point supports for brake beams, the objectbeing' to provide third point supports as at present used with means whereby they are prevented from tilting or canting over the nose of the strut and thereby occupying an inoperative position.
In the drawings 1 indicates the spring plank of a truck and 2 the inclined track or support mounted thereon.
3 is the compression member of the brake beam, l the strut thereof, 5 the tension memher, and 6 the forwardly extending nose which is perforated to provide a pivotal support for the shoe 7 cooperating with the inclined supporting track 2. The nose 6 is usually bifurcated and in order to prevent the shoe 7 from tilting upwardly and riding on the strut, in this manner occupying an inoperative position, I propose to secure a projection 8 on the shoe which extends between the bifurcations of the nose of the strut and prevents the shoe from occupying other than normal positions. In Figs. 1 and 2, this extension 8 is secured directly to the shoe; in Fig. 3 there is a face member 9 between the bifurcations of the strut held 1n position by a bolt 10 for preventing the shoe from riding the strut; in Fig. 4 the extension is secured to the bottom flange of the shoe instead of to the inside flange thereof as shown in Figs. 1 and 2, the extension being given a quarter turn, and in Fig. 5 the extension 11 is secured to the bottom flange of the shoe and up along the side of the web thereof, the inner flange being cut away to enable the extension to occupy its intended position.
While there may be other forms of extensions capable of use for the purposes herein described, and such other forms may be secured in various ways to the shoe or third point support, I-therefore do not wish to be limited to the specific forms shown as my invention comprehends the utilization of some form of separable attachment to the commercial form of third point support to prevent said third point support occupying an inoperative position.
What I claim is:
A third point support for brake beams comprising the combination of a strut and third point support pivotally connected thereto, and a separate projection mounted on said third point support and cooperating with a part of the beam whereby said third point support is prevented from rid-v ing the strut.
In testimony whereof I hereunto aflix my signature in the presence of two witnesses, this fifteenth day of March, 1916.
PHILIP B. HARRISON.
