9 Claims. (Cl. 105-166)
My invention herein relates to trucks ior‘high
speed transportation systems including a track
and self-propelled vehicles or" the coach type,
either singly or in trains, and has for its principal
5 object as delineated and described in this portion
thereof, a truck which makes available the use
of pneumatic tires on vehicles of this character
that are adapted to run on steel rails.
The» frame I is carried by the axle housings in .
Vthe same 'manner as shown in my Patent No.
2,076,914, heretofore referred to, that is the end
housings are swingable With respect to the axis of
the frame and the center. housing is movable in
a plane normal to the said axis, to provide for
movement around a curve without binding in the

guided by steel rails in which the side walls oi
the pneumatic tires are kept out of contact with
represent means of applying power to the axles
the rails at all times.
Another object of my invention is a self guided
truck of the character described in which the
guiding is done by horizontal wheels which may
be tired with either pneumatic tires or hard rub
ber tires and in which the guide wheels are kept
in physical contact with the rail member and are
rshiitable with respect to the leading and trailing
axles to make the truck reversible as to direction.
Another object of my invention is an articu
lated truck of the character described in which
a pair of guide wheels is placed at each end of
the truck in such a manner that a horizontal line
drawn through the axes of the guide wheels will
lie in a plane substantially ahead of the axes of
the leading wheels of the truck that turning
moment may be applied effectively to the lead
ing pair of wheels.
Motor housings 3, Il, and 5, diagrammatically
6, l', and 8, thence to the load wheels, 9, I0, II,
I2, i3, and I4 which are shown to be equipped
with pneumatic tires, not given a specificV numeri
cal designation.
The motor housings 3, 4, and 5 diagrammatical
ly rep-resent any means of applying power to the
axles, the wheels and thus power to the truck to 20
propel the car.
Articulation arms 3a, 4a, 4b, and 5c are shown
integral with the motor housings 3, d, and 5 and
are pivoted together at 26, the pivots being equi
distant from the axles.
A preferred cross section of track is shown in
Fig. e in which I5 represents the tread upon
which the wheels such as 9 and I2 will roll and in
which I6 is an integral upstanding ñange against
which the guide wheels Il' and i6 are adapted to
bear in the manner hereinafter pointed out in
Numerous other objects will be apparent to
those skilled in the art to which this invention
appertains or is most nearly connected, and which
are set forth in the subjoined claims.
The structure herein shown is alternative to
that shown, described and claimed in my Patent
No. 2,076,914, patented April 13, 1937.
A drawing accompanies and forms a part of this
40 speciñcation in which,

The guide wheels i?, i8, IS, and 2€) are rotat
.ably mounted at Ila, Ißa, I9a and Zûa. The
guide wheel frame 2i, is preferably of rectangu
lar general outline with suitable bracing and is
provided with a pair of mountings such as 2Ia
and 2lb that are arranged to be longitudinally
movably mounted in the guides 3b and 5h but are
restrained against other movement.
An important feature of this construction which
is set forth _in detail in my patent hereinbefore re~
ferred to, is the manner of articulating the units
lof the truck by the articulation joints such as
25 and 26, which are shown to be equidistantly
spaced between the axles, in this case three. Also
asV disclosed in the patent referred to, abutting
>arcuate bearing surfaces are’provided at each '
end of the end axle mounting, which are in fric- p '
tional contact with adjacent portions of the frame
I. This provision always keeps the endV axle
mountings in the same relative position With re
