SAFETY BRAKE HANGER.

Application filed November 3, 1924. Serial No. 747,551.

This invention relates to the hangers for the brakes of railway cars, and has for one of its objects to simplify and improve the construction and increasethe efliciency and utility of devices of this character.

Another object of the invention is to provide a device of this character whereby the brake head and shoe are prevented from being displaced in event of the breakage of the I I upon the opposite sides of the adjacent part hanger.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention- Figure 1 is a side elevation of the improved device with the brake head, a portion of a truck frame and one of the flanged wheels in broken lines.

Figure 2 is a front elevation with the truck frame in section on the line 22 of Figure 1, looking in the direction of the-arrow.

the brake beam in transverse section, with the hanger in its highest position.

Figure 4 is a rear elevation of the parts shown in Figure 2.

Figure 5 is a view similar to Figure 4,

- with the hanger device adjusted to its lower position.

Figure 6 is a front view with the parts arranged as in Figure 5, and without the brake shoe.

Figure 7 is a View similar to Figure 4, illustrating a modification in the construction.

Figure 8 is a detached perspective view of the modified construction of the hanger represented in Figure 7 The improved hanger may be adapted without material structural change to the brake shoe heads or supports of various forms and sizes, and it is not desired to limit the device to any specific construction of the shoe or head, but for the purpose of illustration is shown applied to a conventional shoe, head and beam, in which 10 represents the brake beam, 11 the shoe support or head, 12 the shoe, and 13 the holding wedge.

Formed through the head 11 are spaced sockets 14 and 15 to alternately receive the Figure 3 is an enlarged side elevation with hanger and thereby adjustablysupported, as hereafter explained I .The body of the improved hanger is formed of a single section or red, preferably steel bent into el-shape and thereby including a transverse portion 16 and spaced sides 17 and 18, the latter bent into terminal attaching eyes 19 and 20..

The eyes 19 and 20 are designed to bear of the truck frame, indicated at 21, and secured thereto by a bolt 22 extending through the eyes and through the intervening portion of the truck frame.

By this means the brake head or frame and the shoe are swingingly supported from the truck frame. V

The greatest strains on the U-shaped frame occurs at the junction of the sides 17 and 18 and the transverse portion 16, and to reinforce this portion, and prevent the fracture, if any occurs, from releasing the brake head or shoe, a link 23 is provided with eyes 24 and 25 at the ends to slidably engage the sides 17 and 18 of the hanger.

y this means the sides 17 and 18 are effectually prevented from spreading and becoming detached from the brake head.

As shown in Figure 3 the transverse por tion 16 of the Ushaped frame is positioned in the upper socket 14 of the head 11 and when in this position the connecting link 23 lies upon the top of the head as shown. The hanger may also be disposed to position the transverse portion 16 in the lower socket 15 of the head and when in this position the cross connecting link 23 may be seated in the upper socket 14 as is clearly shown in Figures 5 and 6.

The member 16, 17 and 18 being formed in one piece, and the eyes 19 and 20 integral with the sides 17 and 18, can be cheaply constructed with minimum of labor and of suflicient strength to withstand the strains to which they are subjected when in use.

In Figures 7 and 8 the link 23 is shown with an intermediate band 26 to adapt it to head members having intermediate webs 27;

The preferred embodiment of the inven tion is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention what is claimed is:

1. A brake head having spaced sockets and adapted to support a brake shoe, a U shaped hanger having spaced sides and adapted to be coupled to a car truckand alternately engageable in said sockets, a link having terminal eyes slidably engaging the spaced sides of the hanger and adapted to rest upon the brake head when the hanger is disposed in one of said sockets and engageable in one of the sockets when the hanger is disposed in the other socket.

2. The combination with a brake head having spaced transverse sockets and a hanger including spaced sides and a transverse portion for alternate engagement in said sockets, of a link member extending directly between said spaced sides and with terminal eyes slidably engaging the same, said link device bearing upon the brake head when the hanger is in one position, and engaging in the one of the sockets when the hanger is in another position.

In testimony whereof, I afiix my signature hereto.

BENJAMIN F. HULL.
