UNITED STATES PATENT OFFICE.
STEPHEN D. REYNOLDS, OF HOUSTON, TEXAS.
RAILROAD MOTOR-CAR.
950,241. Specification of Letters Patent. Patented Feb. 22, 1910.
Application filed July 12, 1909. Serial No. 507,066.To all whom it may concern:
Be it known that I, STEPHEN D. REY-
NOLDS, a citizen of the United States, resid-
ing at Houston, in the county of Harris and
5 State of Texas, have invented a new and
useful Improvement in Railroad Motor-
Cars, of which the following is a specifica-
tion.
My invention relates to new and useful
10 improvements in rail road motor cars. Cars
for this purpose now commonly in use, if so
constructed that they can be knocked down
to be loaded on passenger trains, have the
load disposed over one rail with a guide
15 wheel, or wheels to travel on the other rail.
This necessitates the front wheel of the
loaded side to be so set as to have a lead
across the track to keep the side pull of the
guide wheels from throwing the car off of
20 the track; therefore the front loaded wheel
grinds against the rail at all times, which
requires greater power to propel the car,
than would otherwise be necessary, and fur-
ther any little variation or obstruction will
25 cause the car to jump from the track on ac-
count of this side pull. Cars now commonly
in use that have the weight equally divided
over the track, are made in one rigid frame
and therefore can only be transported by
30 freight trains.
My invention aims to overcome.these dif-
ficulties, by the provision of a car with four
wheels and a narrow frame suspended there-
between over the center of the track. The
35 four wheels being provided, each with a
short axle hung in a truss support detach-
ably connected to the center frame.
Other novel features will be hereinafter
pointed out and fully described.
Finally the object of the invention is to
provide a device of the character described
that will be strong, durable, efficient, and
simple and comparatively inexpensive to
construct, also one in which the several parts
r5 will not be likely to get out of working
order.
With the above and other objects in view.
the invention has relation to certain novel
features of construction and operation, an
50 example of which is described in this speci-
fication and illustrated in the accompanying
drawings, wherein:
Figure 1 is a side elevation of the motor
car assembled, Fig. 2 is a plan view of the
55 same, Fig. 3 is a rear elevation, Fig. 4 is a
detail of one of the standards, Fig. 5 is adetail in perspective of one of the coupling
sockets, Fig. 6 is a detail in elevation of one
of the standards and its connections, Fig. 7
is an elevation of one of the units or de- 60
tachable axle supports, Fig. 8 is a face view
of one of the axle couplings, Fig. 9 is a lon-
gitudinal section of the same, and Fig. 10 is
a vertical section of one of the short axle
bearings. 65
In the drawings, the numeral 1, designates
the top longitudinal side bars of a central
frame and 2, the bottom longitudinal side
bars, the bars being arranged one over the
other on each side. Near each end of the bars 70
1, couplings 3 are secured and adapted to
receive horizontal end bars 4. This con-
struction is supported by standards 5-formed
of vertical rods or tubular members having
their upper ends engaged in the couplings 75
3; while their lower ends are fastened in
couplings 6. The couplings 6 at each end of
the frame are connected by a cross bar 7.
These couplings 3 and 6 are separated on
the bars 1 and 2 for the purpose hereinafter 80
described.
By observing Fig. 3, it will be noted that
the frame presents a substantially rectan-
gular shape in cross section and is compact,
and rigid. The frame is particularly nar- 85
row and hangs over the center of the track.
I have shown the bars as constructed of
tubing or rods, but it is to be understood
that they may be made in other forms and
shapes. The frame forms one unit of the 90
car; while the axle supports, each constitute
one of the four other units of the motor car.
As each of the axle supports is a dupli-
cate of the other, a description of one will
be sufficient for all. The axle support com- 95
prises an elongated bottom plate 8, on which
and near the outer end thereof, an axle bear-
ing 9 is supported and adapted to receive a
driven axle 10 on the extreme outer end of
which the usual track wheel 11 is secured. 100
This axle extends inward, passing through a
brace 12 and having near its inner end, an
axle coupling collar 13, beyond which the
shaft projects a short distance as is shown
in Fig. 7. 105
As shown in Fig. 6, between each coupling-
6 a collar 70 engaging the bar 1 is forme
with a split lug 14 adapted to receive the
inner end of the bottom plate 8, which is
removably held therein by a bolt 15. The 110
outer end of the bottom plate is looped to
receive between the plates 90 of the bearing
