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»

full strength ofthe metal at the angle of the

30 erally to improve this class‘ of. devices ‘so as to in

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

receive bolts, rivets or similar fastening devices I8 55
