‘ RETAINER MEANS‘ FOR ‘BRAKE HANGERS ‘
Malcolm S. Johnson, Chicago, Ill., assignor to
Illinois Railway Equipment Company, Chi
cago, I‘lL, a corporation of Illinois
Application ‘November 14, 1936, Serial No. 110,843
5 Claims.
(Cl. 188—-209)
My invention relates to retainers whereby the
link hangers for the brakes of railroad cars are
7 pendently secured in place in the usual sockets
or pockets formed by laterally disposed lugs or
‘5 brackets which are generally integral with the
truck frame.
The invention contemplates the use of the con
ventional link hangers and has for its object
the provision of a pair of complementary mem
bers, identical in construction and each tapering
toward one of the ends so that'when arranged
in superposed hanger receiving relation, the ta
pered surfaces will ride on each other and induce
a vertically spreading action whereby the mem
bers are forced into snug wedging relation with
the top and bottom walls of the retainer and
hanger receiving pocket or socket of the truck
frame.
My invention also contemplates means involv
ing a pair of hanger channel providing members,
identical in construction so as to permit inter
change or reversal of the superposed members
in order to compensate for any wear that may
take place on the lower hanger supporting mem
ber; the outer faces of the members and the upper
and lower walls of the pocket or socket of the
truck frame being provided with interengaging
surfaces whereby the members are held against
lengthwise and transverse movement.
Another object of my invention is to provide
retainer means which may be easily applied and
which will afford proper brake shoe key clearance
during replacement operations of brake shoes.
The above enumerated objects and advantages,
C: or as well as other advantages inherent in the de
vice, will all be fully comprehended from the
detailed description of the accompanying draw
ing, wherein
Figure 1 is a side elevation of the supporting
arm or bracket of the truck frame, of which
only a portion is shown, illustrating my improved
retainer means in place and the lower portion of

ceiving side of the element.
My improved retainer means is intended for
use with truck frames provided with a properly
positioned and disposed hanger receiving pocket
or socket whereby the hanger with attached
brake head will be pendently supported in place
adjacent the wheels of the truck.
In the exempli?cation of the invention, a por 10
tion of the truck frame is shown at H! provided
with a laterally disposed bracket or arm H with
the outer end of this bracket or arm formed to
provide the vertically spaced walls l2, l3 united
along one longitudinal side by the arcuate wall 15
portion M, see Figures 2 and 5, whereby an open
ended pocket ‘or socket is provided which also
is open along one longitudinal side. The vertical
ly spaced wall‘portions vl2, [3, as can clearly be
seen in the drawing, provide a pocket or socket 20
adapted to receive the brake hanger or link, a
portion whereof is shown at [5 in Figures 1, 2
and 3.
The pocket or socket in the supporting arm is
of dimensions su?icient to also receive a pair of
complementary retainer members It which are
‘identical in construction.
.
.
These retainer members‘ consist of elongated
plates or ‘castings of su?icient thickness, with
one face provided with an arcuate groove H ex- ‘P
tending from ‘end ‘to end intermediate of the
sides; the semi-circular grooves of the two mem
bers or plates I6 when in proper superposed
relation being ‘ intended to provide a circular
groove or channel for the upper end ‘of the hanger 35
I5.
'
~
'
’
One end ‘of each plate is provided with a
laterally disposed lobe or ear 18 extending toward
the grooved side of the plate or member iii and
substantially at right angles to the groove of the 40
member. The lobes of the two members‘ are
apertured as at l9 to receive a suitable bolt 2:1),

The outer face of each plate or member i6 is
provided with the intersecting or crossing grooves 45
2|, 22, see Figure 4, for the purpose of matching
surfaces formed on ‘the inner sides of ‘the walls
l2 and I3 of the pocket or socket oi the truck ‘
frame arm ll. That‘is to say, the one wall, for
example the upper wall l2 of the socket, is pro 50
vided with a rib 23 disposed ‘lengthwise of the
wall and hence from end toen‘d‘ of the socket,:as
shown in Figure 5; while the lower wall l3 of the
socket is provided with a pair of intersecting or
crossing ribs Hand 25, see Figurer5.

It is apparent from the structure shown and
described that either plate or member I6 is adapt
ed to effect interengaging relation with either
the top wall or the lower wall of the socket.
If the plate or member l6 shown in Figure 4
is placed in the bracket arm socket adjacent the
upper wall l2, the longitudinal groove 2| of the
member or plate IE will register with and receive
rib 23 and thus prevent movement of the plate or
member l6 toward the open longitudinal side of
the pocket or socket, If the plate or member I6,
as shown in Figure 4, is inverted, its longitudinal
groove 2| will receive longitudinal rib 24 on the
lower wall I 3 of the socket while the groove 22
15 of plate I6 will receive the transverse rib 25 on
the lower wall iii of the socket.
Both plates or members I6 taper or increase in
thickness from one end toward the other; that is
to say the plates or members increase in thick
ness toward the end provided with the lobe l8,
as can more clearly be seen in Figures 1 and 6;
the extent and direction of the taper being more
clearly shown at the abutting edges between the
upper and lower plates and indicated by the ref
25 erence numeral 26 in Figure 1. It is evident that
with the sloping longitudinal edges, a vertically
directed wedging action will be provided when
the lobed ends of the two plates or members are
forced in a direction toward each other and
hence the plates or members will be forced into
vertical binding relation with the upper and lower
walls of the socket in the bracket arm.
In assembling my improved retainer means,
the upper end of the brake hanger I5 is placed
in the groove I‘! of one of the plates or members
I 6; the hanger holding member I6 is then insert
ed through the open longitudinal side of the
bracket arm socket and the criss-cross groove
side or face of the member I6 brought to rest
40 on the lowerwall l3 of the socket. With the
criss-cross grooves 2l—-22 on the outer face of
the member l6 receiving the corresponding ribs
24-25 on the lower wall l3 of the socket, the‘
member will be held against movement both 1on
45 gitudinally and transversely of the socket. By in~
verting the plate or member l6 from the posi
tion shown in Figure 4 (so the hanger receiving
groove 11 is disposed upwardly) it is apparent
that the lobe I8 of the member will be disposed
50 at the right hand end of the bracket-arm socket
as viewed in Figures 1 and 5. After positioning
the member with the hanger as above described,
the second plate or member l6 (identical with
the one shown in Figure 4 and positioned as there
55 shown) is then endwisely slid into the bracket
arm socket with its groove l1 facing downwardly
toward the hanger and the lower plate or mem
ber H5.
The upper plate or member I6 must be inserted
60 from the left hand end of the pocket or socket
as viewed in Figures 1 and 5 because the lobe l8
of the ?rst inserted plate will prevent insertion
from that end of the socket.
The insertion of the upper plate is effected by
65 introducing the tapered or thinner end of the
plate (see Figure 6) with the groove 2| aligned
with the rib 23 of the upper wall of the socket
thereby causing the perimeter of the plate to
ride along the perimeter or longitudinal edges of
the lower plate. After the upper plate has been
inserted as described the bolt 20 is then inserted
through the ears or lobes l8 of the two members
as shown in Figures 1 and 3, the head of the bolt
engaging one of the ears while the other ear or
-75 lobe is engaged by the nut or nuts 21 when the
latter are screwed up on the bolt 20 thereby tend
ing to move the plates or members in opposite
directions lengthwise of each other, causing the
plates to wedge upwardly and downwardly into
greater binding relation with the top and bottom
walls of the bracket and hence will prevent any
chatter between the retainer means and the
bracket arm. It will be understood, of course,
that the opposite longitudinal movement is of
but slight degree, such movement being possible
because of the slight differences in dimensions
between the grooves and the ribs which result
during the casting or formation of the various
elements of the structure.
The exempli?cation of the invention as dis
closed in the drawing is believed to be the best
embodiment, but certain modi?cations may pos
sibly be made within the scope of the invention as
de?ned by the appended claims.
