Application September 28, 1934, Serial No. 745,845
12 Claims. (Cl. 213-75)
The present invention relates generally to car hand coupling members shown, respectively, in
coupling devices and has for its principal purpose
a provision of new and improved car coupling
means particularly adapted for independently
5 supported cars and arranged to connect the cars
together so that side sway, rocking, and lurching
are materially reduced while accommodating all
curvatures and grades in the track.
Our invention is particularly concerned with
,10 the provision of coupling means for light weight
rail cars for high speed trains having two or more
separately supported cars having at least'two
trucks for each car, as compared with articulated
cars in which three trucks are used to support
15 two cars. According to the principles of our in
vention, each coupling device is in the nature of a
universal joint which permits the cars to go
around curves and up and down grades, but if
one car should start to rock or sway, or otherwise
20 shift its position laterally or vertically, such
movements are resisted by the inertia of the
other car, since the only relative movements per
mitted between the cars is that of swinging about

suitably spaced apart and connected to

curely riveted together to secure a strong sturdy
supporting beam for the car, as is Well known.
The car coupling illustrated in Figure l in
cludes a ?rst casting or coupling member E0 in
cluding a generally rectangular body section II 15
securely riveted, as at 12 and I3, to one end of
the car beam I, being thus permanently secured in
this manner to the car. The ?rst casting member

vided with a pair of bearing arms l6 and H carry 20
ing bearing caps l9 and 20 adapted to be secured
thereto by bolts 23. In the form of our invention
shown in Figures 1 and 4, preferably the sections

cars in the form of a universal joint which per
mits the cars so connected to swing about either
a horizontal or vertical axis in accommodating
30 curves or grades in the track while imposing upon
one car any tendency for the other car to shift
vertically or laterally, or rock about a longitudinal
axis.
A futher object of the present invention is the
35 provision of a car coupler which will force the
cars to rock together so that when there arises
any tendency for one car to rock, such motion is
restrained by the inertia of the other car.
These and other objects and advantages of the
40 present invention will be apparent to those skilled
in the art after a consideration of the following
detailed description, taken in conjunction with
the accompanying drawings.

Referring now to Figure 1, the reference nu
meral I indicates the central supporting beam of
the car. The supporting beam l is preferably in

25
The second coupling member is indicated in
Figure 1 by the reference numeral 25 and simi-n
larly includes a body portion 28 disposed between
the top, bottom and side plates 4, 5 and 6 of the
beam l of the other car and a yoke section 21 30
having its upper and lower ends terminating in
upper and lower bearing arms 29 and 30. Like
the bearing arms [6 and H, the arms 29 and 30
are also provided with bearings caps BI and 32
35
secured to the associated arms by bolts 34.
The third element of the universal joint cou
pler in the modification shown in Figures 1, 2
and 4 is in the form of cruciform pivot block 35
having end portions 36, 37, 38, and 39 extending
outwardly at substantially right angles to each 40
other.
The ends 38 and 39 are arranged to re
ceive thrust washers 4! by which the ends 38 and
39 bear against the laterally inner sides of the
bearing arms [6 and H. The bearing arms 16
and IT carry circular closure plates 43 to keep 45
dust, dirt and the like from the studs or‘ pins 4!],
as best shown in Figure 1. A flange 45 is pro
vided on the first casting member l0, and a simi
lar flange 46 is carried by the other casting mem
ber 25, and these ?anges are riveted to the trans 50
verse channels 48 on which the car floor is sup-
ported.
As best shown in Figure 2, the pivots 40, as
sociated with the ends 33 and 39 of the pivot
block 35, provide a horizontal axis about which 55
2

the pivot block 35 can swing. The upper and
lower end portions 36 and 31 of the cruciform
block 35 are adapted to be received between the
bearing arms 29 and 36, as best shown in Figure
l, and thrust washers 50 are employed to trans
mit the vertical thrust from the cruciform block
35 to the yoke 27. The ends 36 and 31 of the
pins or studs 46 described above, carried by the
ends 38 and 39 of the cruciform pivot block 35.

described previously, including bearing caps 83
and 84 which receive pivot pins, similar to- the
tened, as by a screw, to the upper end of the pivot
pin 52 and serves the purpose of keeping the pin
15 52 from dropping out of the bearing arms 29 and
36 and maintaining it against endwise displace
ment. It will be noted that the pivot pin 52 and
the arms 29 and 30 provide for the swinging
movement of the block 35 about a generally verti
cal axis as de?ned by the pin 52. Since, in the
form of our invention shown in Figures 1, 2 and 4,
the yoke sections l5 and 21 are preferably formed
as an integral part of the body casting sections l I
and 26, respectively, coupling and uncoupling the
25 cars is accomplished by inserting and removing
the pin 52.
Referring now to Figures 3 and 5, which illus
trate another form of my invention, it will be
observed that the casting member having the
'30 vertical yoke is of the same construction as the
corresponding member shown in Figure 1, and for
understood that our invention is not to be limited
to the speci?c details shown and described above,
but that, in fact, widely different means may be 15
employed in the practice of the broader aspects of
our invention, as de?ned in the appended claims.
What we claim, therefore, and desire to secure
by Letters Patent is:
1. A pair of cars having longitudinal frames 20
in endwise alignment and a universal coupling
between said frames comprising a pair of cast
ings rigidly secured to the adjacent ends of the
frames, each of said castings having yokes
formed integral therewith, the yokes of one of 25
said castings being disposed in a generally verti
cal position and the yokes of the other casting
being disposed in a generally horizontal position,
and a pivot block having pivots ?xed with re
spect to each other and received directly by said 30
yokes, respectively, to provide for permissive rela

As far as the pivot block 35 is concerned, in the
spect to the other about a generally longitudinal
form of the invention shown in Figures 3 and 5,
the end portions 38 and 39 are not spaced quite
so far apart as in the construction shown in Fig
40 ure 2, as will hereinafter appear.
Referring now more particularly to Figure 3,
it will be observed that the left hand casting
member, indicated in its entirety by the reference
numeral 66, comprises two separate sections, a
45 body portion 6| and a yoke section 62. The body
section 6! is disposed between the top, bottom and
side plates of the car beam in the same manner
as has been described above and is securely

arms on ‘one of said sections being disposed gen
