JOSEPH J. SHIRLEY, OF GRA BURY, TEXAS.
SPRING-FRAME FOR FREIGHT-CARS.
SPECIFICATION forming part of Letters Patent No. 235,462, dated December 14, 1880.
Application filed May 27, 1880. (Yo model.)To al whom it may concern :
Be it known that I, JoSEPEJ. SHIRLEY,
of Granbury, in the county of Hood and State
of Texas, have invented certain new and use-
5 ful Improvements int the Use of Springs in
Transportation; and I do hereby declare that
the following is a full, clear, and exact descrip-
tion of the invention, which willenable others
skilled in the art to which it appertains to
to make and use the same, reference being had
to the accompanying drawings, which form a
part of this specification.
Figure 1 represents a longitudinal sectional
view of a car equipped with my improved
i5 spring-padding. Fig. 2 is a similar view,
showing a modification in the arrangement of
the springs; and Fig. 3 is aview of one of the
platforms resting upon or against springs and
supporting the merchandise,
20 Corresponding parts in the several figures
are denoted by like letters of reference.
This invention relates to vehicles for the
transportation ofmnerchandise; and it consists
in providing such vehicles with an interior
25 spring-padding, and in some cases with inter-
mediate elastic floors or partitions, by which iin-
jury to the load, by jolting while in transit,
shall be prevented, and which shall further
conduce to the preservation of fruits and other
30 merchandise of a like perishable nature, by
causing a forced circulation of air around the
Packages of goods, as will be hereinafter more
fully shown and described.
My invention, the nature of which renders
35 it specially adapted for railroad freight-cars,
is fully illustrated in the accompanying draw-
ings, where A represents the body of an ordi-
nary box-car. B B are frames, suitably con-
structed of wooden or metallic slats, or both,
40 and supported upon springs C C, which may
be coiled, elliptical, or of any other suitable
kind. If desired, theframes mayhoe connected
in patirs by said springs, as shown in the draw-
ings, thus forming, practically, spring-mat-
45-tresses which may be conveniently handled
and placed in position.
These spring padding frames are placed in
the bottom, at the ends and sides, and even
under the roof of the car. The positions may
0o be varied according to the kind and class ofmerchandise to be transported, which said
merchandise is then packed in the car, where
it is supported upon, between, and under the
said spring-frames.
Between the several rows, tiers, or piles of 55
crates, boxes, or other packages of merchan-
dise, 'eparate spring-frames, D, may be inter-
posed, as shown in Fig. 2, in a horizontal or
vertical position, as the case may require.
I provide the frames B with slatsor clamps 60o
E, adjustable by thumb -screws F, to clamp
and hold the crates or other packages securely
in position while in transit, and at the same
time einable air to circulate freely between
them. 65
From the foregoing description, taken in
connection with the drawings hereto annexed,
the operation and advantages of my invention
will be readily understood.
The spring-frames upon which the merchan- 70
dise is supported prevent injury thereto by
jolting while in transit, while at the same
time the easy swinging motion, and the fact
that the several packages are spaced from
each other, tends to promote a free circulation 75
of air, which, especially if the air be artificially
cooled, greatly assists in preserving perisha-
ble goods from destruction.
The spring-frames are simple, cheap, and
easily applied to boxcars of the ordinary con. 80
struction.
I am aware that freight-cars have been pro-
vided with movable bottoms supported on
springs resting beneath upon the timbers of
the main ear-frame. This, however, I do not 83
claim but,
Having thus described my invention, I
claim and desire to secure by Letters Patent
of the United States-
The combination, with a vehicle for the 90
transportation of merchandise, of the spring
padding-frames B, having adjustable slats or
cleats E, as and for the purpose set forth.
In testimony that I claim the foregoing as
my own I have hereto affixed my signaturein 95
presence of two witnesses.
