5 Claims. (Cl. 105-—4)
This invention relates to cars of the type some
times called articulated cars, and which com
prise two or more sections having separate car
bodies with adjacent ends articulated to and car
ried by a common truck. And the principal ob
jects of the invention are to provide great
strength and security with free jointed or artic
ular movement of the range required for railway
service and to simplify the end sill and center
10 plate structures.
Further objects and advantages will appear as
the disclosure proceeds and the description is read
in connection with the accompanying drawing in
Fig. 1 is a perspective view with the several
parts slightly displaced and one end sill broken
away to better show the general forms and rela
tions of parts;

are ‘separated by antifriction or self-lubricating
material 32, preferably of that type comprising
porous metal charged with lubricant, and thereby
providing self-lubricating bearings.
The ?ange 29 of the center plate I‘! merges
into side faces 33 (Fig. l) of considerable vertical
width, and they all join what may be called the
body portion of the center plate bracket [6, which
has an upper face machined in steps 34 and 35.
The lower step 34 has a transverse key groove 36 10
and the upper step has a stout dowel 31.
The end sill l2 has, on its lower side, a ma
chined face in steps 38 and 39, corresponding to
the steps 34 and 35. The step 38 has a key groove
4!! opposite to the key groove 36, and receiving 15
with it a key 4!. The end sill also has a Vertical
pocket or bore 42 opening through the step 39,
and receiving the dowel 31.
The body center plate bracket 2| has a ma
chined upper face 43 and‘ a stout dowel 44 which
cooperate with a machined face 45 and a pocket
Fig. 3 is a longitudinal, vertical section along
- or bore 46 of the end sill II, all as best shown in
the center line of the car.v
However, the speci?c form shown and described
is intended for illustration only.
Swing motion trucks are generally preferred
for articulated cars (Car Builders’ Cyclopedia,
1931, pp.g83, 569, 580) but that is a matter of
selection from various types (Ibid., section 10, pp.
763 to 791).
The common truck is here represented by a
bolster I0 and the car bodies by end sills H and
I2. The bolster l0 carries a truck center bearing
a plate [3, having-a pintle l4 surrounded by a con
cave bearing surface I51.
The end sill I2 is equipped with a body center
Fig. 3. A key 4'! corresponding to the key 41
traverses the joint between the faces 43 and 45.
The respective end sills and body center plate
brackets are made fast by bolts 48. It will be ob
served, however, that the form and arrangement
of the several parts relieves the bolts of .practically
all duty except that of mere fastenings.
The holes 42 and 4B for the dowels are formed
in corresponding heads 49 and 50 on the respec
tive end sills, which are ordinarily separated, as
best shown in Fig. 3, by about three-eighths of anv
inch in this selected embodiment.
The bearing surfaces of the truck and body 35
plate bracket, generally indicated at 16 (Fig. 1) center plates are substantially spherical in form,
which bears the body center plate I'I (Fig. 3), ‘ and will, therefore, allow the truck and the re
having an opening [8 to receive the pintle l4, and
presenting a convex bearing surface l9towards
40 the truck center bearing surface i5 and a concave
bearing surface 20 upwardly.
The end sill I I is equipped with a similar body
center plate bracket, generally indicated at 2|,
(Fig. 1) which bears a center plate 22 (Fig. 3)
45 having a bearing portion 23 and an opening 24
for the pintle l4 and presenting a convex bear
ing surface 25 to the surface 20 of the body center
plate ll.
The body center plate I1 has a downwardly di
rected ?ange 26 forming a sort of protecting skirt
for the truck center plate, and an upwardly di
rected ?ange 29, which has a cylindrical inner
surface 30, receiving a corresponding portion 3|
of the body center plate 22.
The actual bearing surfaces of the center plates
spective car bodies to have jointed or swinging
movements relative to each other in all directions
as the car passes over curved pieces of track hav
ing the outer side higher than the inner side, or
as it passes over curves in vertical planes relative
to the surface of the earth.
There are no side bearings between the end
sills and the ‘bolster i3. Instead. the end sills
have arms 5| and 52 pivoted to links 53 which, in
turn, are pivotally and resiliently connected to
the end portions 54 of the bolster III by some
means speci?cally unimportant here.
By slightly'modifying the inner center plate
bracket 2|, the end sill casting ll may be made
identical with the end sill casting [2. Such a
modi?cation would merely entail the provision of
a step similar to the one indicated at 39 on the
outer center plate bracket l6 and increasing the 55
height of the bracket so that the dowel 44 will
properly engage the opening 46 in the head, 49.
Preferably the pintle I4 is hollow so that
bearing face downwardly and a concave bearing
face upwardly, said center plate having a ?ange
center pin may be used if desired.
