`rinother object of the invention is to provide an
This invention relates to railway rolling stock

and consists particularly in novel supporting
structure for the end of a railway vehicle.
There is an increasing demand for light weight
5 trains having cars in which the total weight of a
car and its lading is so light that the car can be
carried on two pairs of-wheels and two axles.
To meet this demand, light weight trains of ar
ticulated car construction are being built with a.
four-wheel truck under the leading end of the
first car and a four-wheel truck under the rear
end of the last car, with the adjoining ends of
adjacent cars carried on one truck of the usual
four-wheel type in common use on railroads.
These trains operate satisfactorily under nor
mal conditions. In the event of a hot box or de
fective journal, wheel, or any other truck part,
articulated car or train _assembly in which one
car can be added to the train or taken out of
the train readily and independently of the ad
jacent cars without requiring cranes or `special 5
trucks, and without duplicating for each of the
adjacent car ends the truck structure previously
provided for the two ends as an assembled unit..
Another object is to provide a car body and
two-wheel truck construction in which the load 10 I
of the car is transmitted from the car body
equally to longitudinally spaced truck holsters
mounted on elliptic springs swingingly supported
by the truck frame and in which the truck-frame
is supported by shock absorbing springs mount 15

arrangement for the vholsters’ and the elliptic

and the entire train is out of service until it can when „cars are rounding curves or due to irregu

train or to add a car or take a car óut o_f the
train without taking the train to the shop where

This is accomplished by providing a car body ì
with means on the ends of cars for coupling to
an adjacent ear, said car body being carried at 25 f
it can be jacked up and the car moved on tem
each end'on a. two-wheel truck by pivoted con
porary trucks or another car on temporary trucks
nection on one side of the axle and a slidable
added to the train.
I am aware that in _Europe many light weight ' bearing at two points on the other side of 'the
passenger cars are carried on two pairs of wheels axle, providing a three-point bearing swiveling
30
-and axles, there being one pair of wheels and an
axle near each end of the car. The axles and
boxes are mounted in rigid pedestals secured to
the car body. Semi-elliptic or other springs are
usually mounted on the axle boxes to support the
car body. i This construction, however, does not
`give satisfactory riding qualities because the ver
tical shock-sare transmitted to the car body di
rectly through the springs mounted on the axle
truck under each end of the car. The truck is 30
provided with two holsters, one on either side of
the axle with pivotal point and bearing prefer--ably cn said holsters, said holsters being sup
ported near their ends on springs, which springs
are mounted on spring planks which in turn are`
supported on swing hangers from the . truck
frame, said truck frame being supported by
other' springs interposed between the journal
_Y
'
boxes and horizontal shocks are delivered boxes and the truck frame.
Another object is to obtain practically the 40
o through the pedestals directly to the body. The »
car body cannot swing laterally relative to the same functioning --of adjacent trucks, individual
wheels or track, the same as cars with ordinary to their respective cars, as is had on an articu
swing motion trucks, so as to absorb or cushion
the transverse forces when the cars are rounding
a' curves and to absorb- transverse and _vertical
shocks due to irregularities in the track.y
The main object off-the present invention is to
provide a car mounted on a pair of lateral motion
trucks. one atv each end of the car, at least one,
but usually both, of said trucks having but one
axle and va pair cf wheels, the car having the
same easy riding' qualities attained byfthe use
lated train where the adjacent ends Íof two cars
are mounted on'a single truck. This ,is accom
plished by connecting the ends of the carste
gether and having the two adjacent two-wheel ’
trucks, coupled together, Vholding the two truck
frames in alinement whereby they act as a single
.four-wheel truck.

The arrangement of the center plate and side
bearings on independently swinging truck bol-~
sters provides for lateral swing of the car rela
tive to the wheels and rail and for pivotal move
ment of the car bodies relative to the trucks and
rail, and cushions the forces transmitted from
10 the rail to the body of the car. While this ar
rangement is substantially different than that
used for the usual four and six wheel trucks in
`
3
tionsÍ independently of- the spring‘suspension of
the truck at the opposite énd of the car.
The
‘ end portions of the car bodies and their trucks
can be disengaged and each car can be moved
valong the track independently of other cars and
hence the advantages of easily associated units
are retained. The truck structure and adjacent
body structure for the articulated unit is simpli
fied without foregoing any of the advantages of
the lateral motion four-wheel truck now used in 10
articulated car structure for supporting the ad
jacent ends of two car bodies.

four and six wheel trucks. »

Whilethe center plate I4 is at the, inner end
of the truck and the side bearings I5 are at
the outer end of the truck, it will be understood
that this arrangement may be reversed or, in
other words, the truck may be rotated 180 degrees

tangent to curved track, it is to be understood
that all features of the invention are not limited 20
to the use of interconnected trucks as illustrated.

on its car body independently of the other truck.
