COMPLETE SPECIFICATION.
Improvements in Dumping Apparatus for Vehicles.
I, HARRY COOPER, residing 948, Pennsylvania Avenue, at San Antonio, in the
County of Bexar, and State of Texas, United States of America, Millwright and
Machinist, do hereby declare the nature of this invention, and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention relates to dumping cars, trucks and similar articles, and the
object thereof is to provide an improved. vehicle of this class with one or more
dumping beds or bodies with improved construction and improved means for
dumping said beds or bodies when desired.
The invention is fully disclosed in the following specification of which the
accompanying drawings form a part, in which;--
Fig. 1, is a plan view of a vehicle embodying my invention and provided with
two dumping beds or bodies, part of the construction being shown in section;
Fig. 2, a bottom plan view of one of said beds or bodies, one side thereof being
broken away;
Fig. 3, an end view of the vehicle;
Fig. 4, a side view thereof; and,
Figs. 5 and 6, are opposite views respectively of a detail of the construction.
In the drawing forming part of this specification the separate parts of my
improvement are designated by the same numerals of reference in each of the
views, and in Fig. 1, of the drawing I have shown a vehicle provided with two
dumping beds or bodies, each of which is of the same form and construction, and
in the following description, only one of said beds or bodies and the operative
mechanism, connected therewith, will be described in detail, it being understood
that both of said beds or bodies and the operative mechanism connected therewith,
are exactly the same in construction and operation.
In Figs. 1 to 4, inclusive, I have shown a vehicle comprising axles 7 provided
with the usual wheels 8, and the front of said vehicles shown in the drawing, is
provided with a suitable device 9 for connecting a tongue therewith.
The said vehicle as shown in the drawing, is provided with two dumping beds
or bodies 10 each of which consists of a bottom 11, outwardly inclined sides 12,
and ends 13, and mounted on axles 7 at each end of the vehicle is an upright
support 14, and each end of the beds or bodies is provided with a plate 15, which
is secured thereto, each of which is provided with a tubular bearing 16, and said
bearing 16 passes through the supports 14, and each of said bearings is provided
at its outer end with a circular head 17, provided on its upper side with radial
holes 18 adapted to receive the end of a bar, or lever by means of which the bed
or body is turned or dumped as hereinafter described.
Connected with the supports 14 and enclosing the circular head 17 of the
tubular bearings 16 are angular frames 19, and pivoted to the outer corner of the
front angular frame 19 as shown at 20, is an angular locking plate 21 the inner
edge of which is adapted to enter a notch or recess 21" in the perimeter of the

page_text: adjacent circular head 17, and said angular plate is provided at its inner front
corner with a notch or recess in which is pivoted a link 22 to which is pivoted
a lever 23, which extends longitudinally of the corresponding frame 19, and
parallel with the corresponding support 14, and the free end of which is provided
with a vertical pin 24 which serves as a handle by which said lever is operated, and
said lever is provided adjacent to its free end with a backwardly directed arm 25,
which is adapted to enter a corresponding notch or recess 25. formed in the peri-
meter of the adjacent circular head 17 as clearly shown in Fig. 1.
The lever 23 is also provided centrally thereof with a backwardly directed lug
or projection 26 with which is connected a rod 27 which passes through the
bottom portion 11 of the bed or body and through each of the tubular bear-
ings 16, and said rod also passes through a tubular bearing 28 fixed in the
bottom 11 of the bed or body. and passing through the ends 13 thereof.
The rear end of the rod 27 is pivotally connected with a link 29 which is
pivotally connected at 30, with the inner ends of the two crank levers 31, which
are pivoted to the corresponding near frame 19 at 32, and said crank levers 31.
are each provided with a forwardly directed arm 33, and the arms 33 are adapted
to operate in connection with corresponding notches or recesses 25 and 21ª formed
in the adjacent circular head 17 as shown.
The crank levers 31 are also each provided at their outer ends with contractile
springs 34, and the inner ends of said springs are secured to the adjacent sup-
nort 14. The object of said springs being to normally throw the inner ends of the
levers 31 and the link 29 outwardly, so as to throw the arms 33 into the notches
or recesses 25 and 21.
In practice, the lever 23 at the front of the vehicle is preferably covered by
the plate or shield 35, which serves to protect said lever, and the crank levers 31
at the rear end of the vehicle are also covered by a shield or plate 36 which serves
for a similar purpose, said shields or plates being both shown at the lower side
of Fig. 1, but being omitted at the upper side of said figure, in order to more
clearly show the construction.
In practice, in order to dump the bed or body, all that is necessary is to take
hold of the pin or handle 24 of the lever 23, and pull the free end of said lever
outwardly. This operation will release both the arm 25 of said lever and the
locking plate 21 from the corresponding circular head 17, and that the same time
the crank levers 31 at the rear end of the vehicle will be operated by the rod 27,
and the arms 33 thereof thrown outwardly and disconnected from the corre-
sponding circular head 17, and the bed or body may then be turned in either
direction, either by taking hold of the side thereof, or by inserting a bar or
Jever into the holes 18 of the forward circular head 17, and after said bed or body
has been dumped it may be turned to its normal position, and locked therein.
The locking plates 21 being thrown into position by the spring 34, to engage
with the circular heads at each end of the vehicle to hold the bed or body in
position till it is again desired to dump it.
It will be understood that after the bed or body has been dumped and returned
to its normal position for loading, the springs 34 at the rear end of the vehicle
operate to automatically lock the bed or body, and to hold it rigidly in position,
until it is desired to again dump the same.
I also provide a supplemental brace or support for the bottom of the bed or
body which comprises a truss frame composed of parallel side rods 36, each
of which is composed of two parts connected centrally by a turn buckle 37, and
the outer side of these rods are connected with plates 13, and the inner ends of
the separate parts thereof pass through or beneath cross plates or stays 38
secured to the bottom of the bed or body adjacent to the middle thereof, and by
means of this construction the bed or body is supported centrally as will be readily
understood.
An outside view of the circular head 17 of the front of the vehicle is given
in Fig. 5, and an inside view thereof in Fig. 6, and as shown in the front view

page_text: only the front circular head 17 is provided with the holes or openings 18 adapted
to receive the end of the bar or lever for turning the bed or body, but it will
he understood that the rear circular head 17 may be also similarly provided if
desired, and many other changes in and modifications of the construction herein
described may be made without departing from the spirit of my invention or
sacrificing its advantages.
Although I have shown my improvement applied to an ordinary wagon or
truck, it will be apparent that said improvement may he applied to any desired
form of vehicle, including railway cars, and it will also be apparent that one or
more of the beds or bodies 10 may be mounted on each vehicle and provided with
the dumping mechanism hereinbefore described.
Having now particularly described and. ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
