(oi. its-21o) ' This invention relates to safety mechanism for a single bracket, however, being shown in the railway cars and more particularly to a combined present instance. The bracket is stamped or 0th» brakebeam and bottom rod support for the brake crwlse formed from a single sheet of metal, one end of which is bent in a vertical plane to form ' rigging thereof. ' v ' ‘an upstanding portion 8 terminating in a down The object of the invention is to provide a com extending hook 9 adapted to fit over the paratively simple and inexpensive device of‘the wardly edge of the flange ill-of the spring board, character described which may be economically upper as best shown in Figure 1 of the drawing. Ex stamped, punchedor otherwise'formed ‘from a tending laterally from the. upstanding portion 3 is single ‘sheet of metal'and in which the bottom rod a horizontally disposed brake beam supporting support or stirrup is offset with respect to the 10 arm ll provided with an upstruck longitudinal vertical plane of the spring board'engaging/ hook reinforcing rib l2 de?ning side ?anges it, the so as to provide additional strength at the junc inner end of the reinforcing rib l2 gradually merg- ' . and consequently prevent accidental bending or ing into the upstanding portion 8 to-form an in Y_ clined brace M connecting the upstanding por 15 breakage of the bracket at the point subjected to _, tion of the stirrup andbrakeheam supporting arm tion 8 and arm H, as shown. the most strain.

Astill further object of the invention is gen 30 erally to improve this class‘ of. devices ‘so as to in crease theirntility, durability and efficiency. In the accompanying drawing forming a part of this speci?cation and in which similar numer als of reference indicate corresponding parts in 35 all the ?gures of the drawing Figure l. is a vertical sectionalview of a portion ' of a railway car-truck showing the safety device - in position thereon, Figure-2 is a' vertical sectional view takenon the’ line 2--2 of Figure 1, Figure 3 is a top plan view, and Figure 4 is‘a perspective view of'one ofthe com plete brackets. ' I The improved safety device forming the sub 45 ject-matter of the present invention is principally designed for application to railway car trucks and by way of illustration is shown in connection with a portion I of a truck in which 5 designates one of the brake beams, 5 the spring board and ‘I. the 50 brake rod which extends beneath the spring board in'the usual manner. The device comprises a unitary structure-in the form of an integral bracket, two of which are preierably used on each truck and arranged in 55 pairs at opposite sides of the a spring board 6, but the opening 65 of which is adapted to receive and support the brake rod 1?. By forming the stirrup l6 integral with the arm Hand‘ extending said stirrupdownwardly at'right angles to said arm and at a point substantially midway between the opposite ends of the’ am, said stirrup will be of _ the proper length to support the brake rod l with out the necessity of bending the lower end of .the rod bracket laterally to prevent track interfer ence, which bending operation would be necessary if the cut or severed portion forming the stirrup were extended to-the angle of the bracket. More over, by forming the stirrup in thismanner full strength of the metal at the angle between the upstanding portion 8 and horizontal supporting arm H is assured and this strength is materially _ ' increased owing to the diagonal hollow-brace l4 connecting the vertical extension 8 with the arm i t. Furthermore, a saving in metal is effected 40 inasmuch as the lower or closed end of the stirrup ' is out directly from the end of the arm H and. ( ‘bent downwardly so that it is not necessary to cut or otherwise trim the blank from which the 45 bracket is formed. The inner wallsof the overhanging book 9 are disposed parallel with each other so as to have a sliding ?t with the, adjacent walls of the upstand ing ?ange ?ll of the spring board and the bill of the hook 9 is made relativelyshort as thisholok 50" merely serves to center ‘and temporarily support the bracket in position on the spring'board B. The‘ upstanding portion 8 of ‘the bracket is pro videdl with onev or more‘ openings‘ l‘l' adapted to‘ receive bolts, rivets or similar fastening devices I8 55 2‘ . , 2,113,900 ' mug openings in‘ _ which extend through co ' ‘ at a point intermediate the length of the arm to the upstanding ?ange'il of , e\spring board and serve to secure the bracket in proper position on form a depending rod supporting stirrup. the spring board. Owing to the fact that the 'bill of the hook 9 is relatively short, said hook bracket having an upstanding‘ portion adapted to bearvagainst the adjacent side of the upstanding . will not form an obstruction or interference when ?ange of a spring board and terminating in a depending hook ?tting over the top of said ?ange, securing the rivets It in position. The bracket is'placed in position on a car truck in the manner shown in Figure 1 of the drawing, that is to say; 5.
