_Referring to the drawings in detail, and ñrst
considering the embodiment of our invention il 30
lustrated in Figures 1 to 9, inclusive, there is
shown a truck l comprising two pairs of wheels
2 and connecting axles 3, only one pair being
illustrated, as the truck is symmetrical. Around
each journal 4 of theaxles 3 is a journal box 5 35
with an associated brass or bearing 6, each jour
nal box preferably having a. pocket 1 in the roof
thereof receiving a hardened steel insert 8 hav
ing a crowned or cylindrically convex upper sur
face 9 normally engaged by the corresponding 40
lower surface’lll of a corresponding block il in
the corresponding jaw l2 of an associated side
frame i3. It is not necessary to describe the
mounting of the side frames -i 3 on the journal
boxes 5, as such mounting is illustrated and pref-' 45
erably corresponds with that described and
claimed in the Barrows Patent No. 1,779,526, of
October 28, 1930, whereby equalizing of the jour
nal box in the vertical axial planes of the jour
nals is permitted.
‘
The rocking engagement between the bearing
blocks 8 and il of the journal boxes 5 and frames
I3 not only permits equalization of the boxes, but
also allows for swinging of the frames on said
boxes, whereby the lower or tension members .M
50

2,066,602
of said frames are adapted to move laterally
when such swinging takes place. Each frame is
desirably also provided with a compression mem
ber I5 and bolster guide columns I6 spacing in
termediate portions of said compression and ten
sion members, leaving a window or bolster open
ing I1 therebetween.
-
The associated bolster I 8 is desirably supported
from the frames I3 by resting at each end, on a
10
bolster bearing -casting I9 which, in turn, rests
on a resilient or rubber pad 20 supported on the
tension member I4 beneath the window opening
I1. Each casting I9 desirably has ñanges which
straddle the tension member .I4 of the corre
15 sponding frame.
The frames I3 of the present
embodiment are preferably of the double truss
type, such as shown in the Barrows Patent No.
1,652,808 of December 13, 1927, so the pads 20
and bearing blocks or adapter castings I9 are
20 formed to clear the reinforcing or double truss
portions 2I of the frames.
The upper surfaces. of the bearing castings I9
and the engaging surfaces of the holster I9 are
formed so that rocking therebetween is permitted
25 without gouging. In the present embodiment,
the upper surfaces of the castings I9 are formed
brake hangers 40 at al1 times to hang in proper
relation with respect to the associated wheels 2,
the trunnions 31 permitting lateral angling of
the hangers 40 to compensate for swinging of
the frames I3, and the pins 39 permitting longi
tudinal angling of said hangers, whereby pro
vision is made for universal movement thereof.
The trunnions 31 are desirably flattened at the
sides, as indicated at 4I, to permit insertion in
the bearings 36 through the channels 42 which 10
communicate with said bearings, said trunnions
being, when in normal position, prevented from
displacement from the bearings, as will be under
stood, particular reference being had to Fig
ure 6.
15
Referring now to theA embodiment of our in
vention illustrated in Figures 10 to 14, inclusive,
a construction is there disclosed which corre
sponds generally with that of the preceding em
bodiment, except that the brake hanger brackets 20
35rt are mounted on the bolster I8“, said brackets
having housing portions 43 >normally receiving
generally cylindrical bearing pieces 44 slotted, as
indicated at 45, to receive the upper apertured
ends 46 of the brake hangers 40“, said brake
hangers being connected to the'bearing pieces 44
generally convex, each with a flattened central ~ by pins 39a. The slots 41 in the housing por
portion, and the corresponding surfaces of the tion 43 -receiving the ends of the brake hangers
bolster are formed generally concave with flat-l 4I!"L are desirably widened, as compared with the
30 tened central portions, the curvature, however,
slots 45, so that the bearing piece in each housing $0
being on greater radii so that rocking or rolling 43 is movable longitudinally of the bolster. Such
therebetween is permitted, the flat central por
longitudinal movement relative to the bolster is
tions serving to cause the bolster to tend to re
main in central~ position so that the truck is self
35 centering. In order to limit lateral motion of the
bolster upon swinging of the frames on the out
side articulated journal boxes heretofore de
scribed, a retaining member or bolt 22 desirably
passes loosely through each end of the bolster
40 and through the guide columns I6 on either side
of said bolster.~ It will, therefore, be seen that
the bolster may move laterally, causing the asso
ciated side frames, only one of which is illus
trated, to act as swing links as they rock on the
journal boxes.
To provide for the adequate resilient mounting
of the associated railway vehicle or car body
bolster 23, the truck bolster I9, adjacent each
end, desirably has an upwardly opening pocket
50 24 formed by downwardly offsetting a portion of
the upper wall thereof, receiving a nest of springs
provided by an extension 48 notched, as indi
~cated at 49, to engage a flange or lug 50 on the
corresponding guide column I6“, so that even
though the bolster I 8a moves laterally the bear
ing piece 44 and the associated brake hanger ‘
stays ’the proper distance from the associated
frame I3a so as to be properly disposed withl re
spect to the associated wheel (not shown). A
retainer 5I desirably serves to prevent loss or
undesired removal of the pin 39‘. It will, there
fore, be seen that although the features of the
present embodiment not shown correspond with
the previous embodiment whereby the side frames
I3"l serve as swing links for yallowing lateral move
ment of the bolster, such lateral movement does
not interfere with the proper relation between
the brake hangers 40* and the associated wheels
(not shown).
A
In view of the foregoing, it will be seen that We
have provided a truck in which the side frames
25. Supported on the upper ends of the springs 25
is a spring cap 26 on the upper surface of which, themselves function as swing links for allowing
between upstanding flanges thereon, are mounted ’ lateral motion of the bolster. -To permit the nec
55 side bearing rollers 21, said rollers, in the pres
essary freedom of motion, we have incorporated
ent embodiment, being preferably ground cones
and having toothed portions 28 at their ends en
. gaging corresponding toothed portions 29 on the
body side bearing 39 to maintain them‘in desired
position. The surfaces 3I on the 'spring cap 29,
and 32 on the side bearing 3l! are desirably con
cave toward each other, so that the truck is made
self-squaring by the raising of the body upon
angling of the truck about the center plate 33,
l65 the lower end of which interlocks in a. corre
sponding pocket 34 in the top of. the bolster but
does not normally serve to support the car body
23 from said bolster.
,
Theside frames ofthe present embodiment are
7.o
preferably provided with brake hanger brackets
35 providing bearings 36 receiving trunnions 31
on brake hanger blocks 98 through which nor
mally extend brake hanger pins 39 which, in
turn, flexibly support brake hangers 4I). The
75 purpose of this flexible mounting is to enable the
the outside articulated journal box’ already the
subject of the Barrows Patent No. 1,779,526 of
October 28, 1930, using conical roller side bear
ings and truck springs between the side bearings
and bolster instead of between the bolster and
side frame. The brake hanger brackets are
either mounted for universal movement with re
spect to the swingable side frames or are mounted
from the bolster with provision for relative lat
eral movement therebetween, whereby the proper
relationship of the brake hangers and the wheels
is maintained.

Although preferred embodiments of ourßinven
tion have been disclosed, it will be understood
that modifications may be made within the spirit 70
and scope of the appended claims, and that V'the
