Patented Mar. 24, 1931 UNITED STATES FREDERIC SGHAEFER, or PITTSBURGH, PENNSYLVANIA BRAKE-HANGER surronr Application filed January 17, 1927. serial at. 161,474.

The invention relates to the attachment of brake hangers to the side frames of railway car trucks, and the object thereof is to pro- The invention is illustrated in the acco-mpanying drawings of which Fig. 1 is a combined vertical sectional view of a portion of a truck side frame and front elevation of a brake hanger bracket extending laterally from the frame; Fig. 2 a sectional view taken on the line'IIII, Fig. 1; Fig. 3 a plan view of the structure shown in Fig.1; Fig. 1 a

vertical central sectional view of a modification of construction; and Fig. 5 a perspective view of the shoe used in the construction shown in Fig. l. According to this invention a truck frame is provided with a bracket which is so shaped as to have an inner vertical wall and upper. and lower horizontal walls forming a slot which is open at its sides and outer end and i closed at its inner end. This bracket receives shoe is positioned in the bracket its hanger receiving opening is closed, preferably bya projection extending laterally from the inner vertical wall of the bracket.

, invention illustrated in Figs. 1, 2 and 3, the upper cord of a truck side frame 1 is shown as being provided with a laterally extending h bracket 2, which is formed integrally with i the side frame although it may be otherwise attached to it. At its outer end the bracket is provided with a vertical wall 3, an upper wall 4, and a lower wall 5 which form a substantially U-shaped slot open at its sides and" outer end. Removably mounted in this slot and 16. The shoe is retained in Having reference to the embodiment of the there isa 'shoe'6 provided centrally with a 7 bearing 7 for the upper portion of a brake hanger 8, the bearing forming part of an open ng 1n theshoe for receiving the brake hanger when it and the shoe are detached from the bracket. The shoe opening is preferably closed by a projection 9 extending laterally from vertical'wall 3' of the bracket, the end of which projection forms with the bearing portion 7 of bearing for the hanger.'

For securely positioning the shoe inthe bracket the outer ends of theshoe are preferably provided with flanges 10 which overhang the upper and lower bracket walls 4 and 5, and for retaining the shoe in positiona removable retaining member 1n the form of e a pin or rivet 11 extends through projecting ends of upper and lower walls 1 and 5. The shank of this rivet is adjacent to the outside of the shoe which is preferably provided with a groove for receiving a portion of it to afford an extended bearing surface. 7 i

In the embodiment of the invention'illus trated in Figs. 4 and 5, the bracket isfpro; vided with upwardly inclined upper and lower walls 15 and 16, and the brake hanger receiving shoe is in the general form of a spool having a central substantially cylindrical bodyportionl'r' and laterally projecting end flanges 18 overhanging the'sides of walls 15 p j A place by'a bolt 20. Otherwise this embodiment of the invention "is the same as that of Figs. 1, 2

and

\Vhile the support maybe used for U- shaped brake hangers having. coni'iecting pins at their upper ends, and for closed link brake hangers, it is particularlyapplicable to the latter type. Inthe illustrative. em bodiment of the invention it is shown in its applicability to closed link brake hangers -aving asymmetric I-beam upper and lower arms or yokes'as described and claimed in my Patent No. 1,470,121, although such hangers having other forms of arms may beused. M i

In attaching a brake hanger to the support provided according to thisinvention, the

removable wearing shoe 6 or 17 is applied to the upper yoke or pin of a hanger and is then the shoe a continuous ATENT lorries i inserted in the slot formed by and between the upper, lower and inner walls of the bracket. A pin or equivalent retaining member is then attached-to the bracket in a position to engage the outer portion of the shoe to hold it in such position that pulls and thrusts of the hanger are resisted substantially directly by the lower and upper walls of the bracket. WVhen worn, the shoe may be readily replaced by merely with-drawing the attaching member and removing the shoe first from the bracket slot and then from the hanger. By the same procedure the brake hanger may be disconnected from the side frame for any other purpose.

According to the provisions of the patent statutes, I have explained the principle and operation of my invention, and have illustrated and described what I now consider to represent its best embodiments. However, I desire-to have it understood that, within the scope of the appended claims, the invention may be practiced by forms of construction other than those specifically shown and described.

I claim as my invention: 1. The combination of a truck frame for railway cars provided with a bracket having an inner vertical wall and upper and lower walls forming a slot open at its sides and outer end and closed at its inner end, an integrally formed shoe removably mounted in said slot and provided with an opening adjacent to and facing the vertical wall of said slot for receiving-the upper end of a brake hanger when the shoe is removed from the bracket, the walls of the opening of said shoe forming upper and lower bearings for the brake hanger, and a removable retaining member adjacent to the outside of said shoe and engaging said bracket for locking the shoe in position. r

2. The combination of a truck frame for railway cars provided with abracket having an inner vertical wall and upper and lower walls forming a slot open at its sides and outer end and closed at its inner end, a shoe removably mounted in said slot and provided with an opening'adj acent to the vertical wall of said slot for receiving the upper end of a brake hanger when the shoe is removed from the bracket, the walls of the opening of said shoe forming upper and lower bearings for the brake hanger, and a removable pin adjaof said slot for receiving the upper end of a brake hanger when the shoe is removed from the bracket, said vertical wall being provided with a projection extending into said shoe opening, and means for retaining said shoe in the bracket.

4;. The combination of a truck frame for railway cars provided with a bracket having an inner vertical wall and'upper and lower walls forming a slot open at its sides and outer end. and closed at itsinner end, a shoe removably mounted in said slot and provided with' an opening adjacent to the vertical wall of said slot for receiving the upper end of a brake hanger when the shoe is removed from the bracket, and said shoe being tical wall being provided with a lateral projec'tion extending into said shoe opening, said shoe beingprovided at its ends with flanges ad acent to the sides of the upper and lower bracket walls, and a removable pin adjacent to the outside of said shoe and engaging the outer ends of said upper and lower bracket walls for retaining the shoe in position.

In testimony whereof, I sign my name.
