UNITED STATES PATENT OFFICE.

CHARLES H. WILLIAMS, JR., OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO RAILWAY EQUIPMENT COMPANY OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

BRAKE-HANGER.

To all whom it may concern Be it known that I, CHARLES H. VILLIAMS, J r., a citizen of the United States, residing at Chicago, Illinois, have invented a certain new and useful Improvement in Brake- Hangers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it a ppertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is an end elevational view of one form of my improved brake hanger. Fig. 2 is an end elevational view of a modified form. Fig. 3 is an end elevational view of another modified form.

This invention relates to a new and useful improvement in brake hangers, the object being to construct a device of the character described which will permit a lateral move-- ment of the brake beams within certain limits to accommodate the brake heads to the lateral play of the wheels.

The growing use of flanged brake shoes on passenger cars has been the cause of considerable trouble in the wear of the brake shoes and the proper application of the brakes. There is a variation allowed in the arrangement of wheels on the axles of one eighth of an inch. There is lost motion between the axle bearing and the journal bars between the wedge and the box; and there is lost motion between the box and pedestal. In other words, the wheels float or vary in the truck frames laterally from one quarter inch to as high as one and a quarter inches, depending upon wear produced by service conditions. If the beams that have a fixed location of heads are tied up to the truck frame by the hangers and to the floating wheels by the shoe flanges, unequal wear will result, and the parts will be strained and broken in service.

The object of my present invention is to allow necessary lateral motion of the beams with flanged shoes to include the limits of the floating movement of the wheels and restrain the beam against excessive movement, so that the same can properly cooperate with the wheels when the brakes are applied. My invention further is designed to maintain a brake beam at a uniform elevation during such movement, and to maintain hangers in perpendicular relationship to a line t 'ansverse the car or truck frame.

Specification of Letters Patent.

Application filed December 11, 1911.

Patented July 23, 1912. Serial No. 665,198.

Several of the forms of my invention are applicable to present conditions requiring no change of head, brackets or hanger end sizes, while another form requires a special head.

In the drawings, referring to Fig. 1; 1 indicates the brake hanger, and 2 the brake shoe, both being of ordinary (JOIlStllltitlUl'l. is the hanger pin and 4 the lugs on the truck frame in which the pin is mounted. These lugs in this form of my invention are spaced apart so as to permit the use of springs 6 therebetween and the brake hanger, whereby the brake hanger 1 may have a. slight yielding movement lengthwise the pin to accommodate the brake shoes to the wheels, the spring thus tending to center the brake hanger when the brakes are relez sed. Of course there are two brake hangers for suspending the brake beam in position, I having shown only the break head on one end of the beam.

In Fig. 2 I have shown a form in which the brake head is widened so as to permit- ;the use of springs 10 on each side of the brake hanger where it is eonnecital to the brake head. If desired, however, these springs may be omitted.

In Fig. 3 I have shown another form in which the brake hanger haslateral play which is similar to the construction shown in Fig. 1,except that the springs are omitted.

What I claim is;

1. The combination of a truck frame, a brake beam, a brake hanger, said brake hanger permitting the brake beam to have a relative lateral movement with respect. to the truck frame, and s n'ings arranged on each side of the brake hanger and bearing against lugs to which it is attached for centering the same.

2. In combination, a truck frame, a brake beam, a brake hanger supported from the. truck frame and having a prcdci'erminml normal angular relationship thereto, and means cooperating with said brake hanger for permitting lateral movement of the brake beam with respect to the truck frame and for maintaining the normal lateral angular relationship of the brake hanger thereto.

3. In combination, a truck frame, a brake beam, and a brake hanger suspended from the truck f 'ame, means for permitting transverse movement of the brake beam and for maintaining the brake hanger in a pertween both sides of the brake hanger and 10 pendicular position relative to the line of one of sald members.

said transverse movement, and means eo6p- In testimony whereof I hereunto affix my ernting with the brake hanger for centering signature in the presence of two Witnesses, the brake beam. this 17th day of November, 1911.
