30 Claims.
This invention relates to brake rigging for a
railway car truck, and more particularly to such
a rigging of the clasp type wherein brake heads
and brake shoes are applied to opposite sides of
5
each wheel.
'
An object of my invention is to provide, a claspv
brake arrangement which will be particularly
suitable for high-speed trains and more particu
larly for trailer trucks of such trains.
10
Another object of my invention is to provide a
clasp brake arrangement wherein the power
means may be mounted in the transverse load
carrying member of the truck, thus conserving
all possible space.
A still further object of my invention is to pro
vide a clasp brake rigging for a four wheel rail
way car truck wherein the rigging associated with
the power means shall be located inwardly of the
wheels leaving the end portions of the truck free
and clear.
Still another object of my invention is to pro
vide a clasp brake rigging of particularly e?‘icient
and simple form wherein independent power
means shall control the rigging associated with
25 each wheel and axle assembly.
With these and various other objects in view,
the invention may consist of certain novel fea
tures of construction and operation as will be
shown) on which the car body may be supported
in the Well-known manner. Adjacent the ends
of the side frames are the integrally formed
pedestals 8 and H] providing therebetween the
jaw opening l2 within which may be received 5
the journal portion 14 of the associated wheel
and axle assembly I6. The ends of the side
frames have the inwardly turned brackets it pro
viding support for the brake rigging at the ends
10
of the truck.
The rigging comprises the hanger lever 20 (Fig
ure 2, right) pivotally supported at its upper end
as at 22 from the bracket l8 and pivotally sup
porting at a point intermediate its ends as at 24
the brake head 26 and the associated brake shoe 15
28 disposed for cooperation with the periphery
pended hereto.
of the adjacent wheel. The brake beam 30 has
the trunnion end 32 which is pivotally connected
to the lower end of the hanger lever 20 and ad
jacent the end of the beam 30 is connected a pull
rod 34 having the slotted end 36, said connection
being made ‘adjustable by means of the manual
slack adjuster 38. The opposite end of the pull
rod 34 is pivotally and adjustably connected as
at 40 to the lower end of the live truck lever 42, 25
the upper end of said live truck lever being piv
otally connected as at 44 to the clevis 45, the
opposite end of said clevis being pivotally con
nected as at 48 to the cylinder lever 50 at a point
intermediate the ends of said cylinder lever. The
live truck lever 42 is pivotally connected at a

Adjacent the juncture of the transom 6 with
the side frame 4 is provided the integral bracket
standing;
connected thereto as at 45. The lower end of the 40
hanger 43 is pivotally connected as at 47 to the
end of the brake beam 56. At the pivotal point
41 on the end of the beam 56 is mounted the
brake head 49 ‘and the associated brake shoe 5|
for cooperation with the opposite side of the 45
before mentioned wheel.
The outer end of the cylinder lever 50 is ful
crumed as at 60 from the bracket 62 which is
secured to the bracket 64 (Fig. 3) integrally 50
Figure 2 is a sectional view of the truck and
brake structure shown in Figure 1, the section be
ing taken substantially in the vertical plane bi
secting the structure longitudinally;
Figure 3 is an end elevation of the truck and
brake structure shown in Figure 1, the View be
ing taken from the right as seen in Figure 1; and
Figure 4 is a fragmentary side elevation of the
truck structure shown in Figures 1 to 3 showing
50 the manner of supporting the brake beams inter
mediate the wheels.
Describing the structure in more detail, 2 rep
resents the car truck having side frames 4, 4
integrally joined by spaced transoms 6 between
55 which may be carried the usual bolster (not
4i (Figure Ll) as ‘support means for the hanger
43, the upper end of said hanger being pivotally
formed as a part of the transom 6 adjacent an
end thereof. Adjacent its opposite end the cyl-p
inder lever 50 is pivotally connected as at 66
to the piston 68 of the power means or brake cyl
inder 10, said cylinder being mounted within said 55

transom 6 and secured thereto as by means of the
rivets 'l2—-'l2.
Adjacent the longitudinal center line of the
truck the transom 6 has the internal integrally
formed shelf 14 to which is secured the bracket
76 by means of rivets 18-18, said bracket having
the extended jaw portion 80 from which is piv
otally hung as by means of the pin 82 the bal
ance hanger 34. The lower end of the balance
carrying member adjacent the longitudinal cen
ter line of said truck, brake rigging comprising
brake heads and brake beams disposed on op
posite sides of each wheel and axle assembly,
hanger levers supporting the beams outwardly
of said wheels, hangers supporting the beams in
wardly of said wheels, live truck levers pivotally
connected at points intermediate their ends to
the ‘beams intermediate the wheels, pull rods ad
10 hanger 84 is pivotally connected as at 86 to the
justably connecting the lower ends of said live
flllCI‘llIl’l 88, said fulcrum being secured to the
truck levers to the beams outwardly of said
middle point of the beam 56 as by rivet means 90,
thus providing a support and balance for the
brake beam.
The bracket 16 is extended longitudinally of
15
the truck to form the shelf portion 92 which
furnishes a sliding support for the inner end of
wheels, cylinder levers having their outer ends
the cylinder lever 50 as at 94, the upper surface
of said bracket being provided with the wear
20 plate 96 and the under surface of the cylinder
lever 50 having the cooperating wear plate 98
(Figure 3).
The parts of the brake rigging at the side of
the truck opposite that just described correspond
in arrangement and function with those just de
scribed as most clearly shown in Figure 1, and
the corresponding parts on the opposite side of
the truck are identi?ed by the same reference
?gures.
In operation, assuming the parts to be released,
30
actuation of the dual power means l9, 70 causes
the pistons 68, 68 to move to the right as viewed
in Figure 1, thus rotating the cylinder levers
5B, 50 around the fulcrums ?ll, 60 at their outer
35 ends and through the clevis means 46, 46 causing
rotation of the truck levers 42, 42 about the ful
crums 40, 40 at their lower ends until the brake
shoes carried on the brake beam 56 are brought
into engagement with the peripheries of the ad
jacent wheels at opposite sides of the truck.
Continued actuation of the power means will
cause the brake levers 42, 42 to rotate about the
fulcrums 52, 52 intermediate their ends, thus
moving to the left the pull rods 34, 34 with their
45 interconnecting beam 30 until the brake shoes
carried on the hangers 29 are brought into en
gagernent with the opposite sides of the periph
eries of the before mentioned wheels.
It will be understood of course that the brake
structure at opposite ends of the truck and also
at the opposite sides of each end are similar.
Accordingly, two brake cylinders are mounted on
each transom on opposite sides of the longitudi
nal center line of the truck and operate in unison
.55 to actuate the brake mechanism at one end of
the truck.
Release of the power means will cause the
brake rigging to move in a direction opposite to
that described as occurring on actuation of the
power means, thus allowing the brakes to assume
their normal position wherein the shoes are
spaced from the adjacent wheels.
It is to be understood that I do not wish to be
limited by the exact embodiments of the device
shown, which are merely by way of illustration
and not limitation, as various and other forms
of the device will of course be apparent to those
skilled in the art without departing from the
spirit of the invention or the scope of the claims.
