Improvements in Dumping Carts.
A communication from MOSES SYMON MCCRANEY, of 233, Dovercourt Road,
Toronto, County of York, Province of Ontario, Canada, Gentleman.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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 :-
The object of the invention is to construct a dump-cart with its body close to the
ground but supported by wheels of large diameter, the shafts of the cart being
connected to the body in such a manner that the strength of the horse may be
utilized for the purpose of dumping, and it consists essentially in rigidly fastening
the body of the cart to a crank axle on which the wheels are journalled so that in
dumping, the journals of the wheels will form the pivot point, the shafts being
pivotted to the body at a point above or below the said axle substantially as and
for the purpose hereinafter explained and also to so support the tail-board that it
will always be held perfectly upright without undue strain on the fastenings.
Fig. 1 is a perspective view of the improved dump-cart in its normal position
with one of the wheels removed and the tail-board in position.
Fig. 2 is a perspective view of the improved dump-cart as it will appear when
dumped and with the tail-board removed.
Fig. 3 is a perspective detail of one end of the tail-board.
In the drawing A represents the body of the cart and B the crank axle bent
upwardly so as to fit closely to the sides of the body A to which body the said
axle B is rigidly bolted or otherwise fastened.
C is a metal plate placed on the inside of the body A immediately over the
axle B.
The ends of the clips which secure the axle B to the body A pass through and
secure the plate C in position the said plate acting as a brace to strengthen the
body of the cart as indicated.
The wheels D are journalled on the axle B as indicated. Owing to the
formation of the crank axle B the body A of the cart may be brought as close to
the ground as desired, while the wheels practically speaking may be made any size
in diameter.
The shafts E are pivotted at a to the body A of the cart. This pivot point
may be made any form desired. In the form shown it is made by an iron strap or
bracket F rigidly bolted one on each top rail G the bracket being shaped to fit
over the end of the shaft E through which the pivot bolt a passes the metal plate C
being shaped as shown so as to strengthen the rail G at the point where the pivot
is formed and the bracket F is held.
The front end of the body A is locked by a removable bolt H or by any other
suitable means.
Owing to the fact that the body A of the cart is rigidly fastened to the crank
axle B and that the said crank axle B is pivotted on the journals of the wheels D
coupled with the fact that the shafts E are pivotally connected to the cart body A
at a point above or below the axle journal, it follows that when the bolt Ĥ or
other fastening is removed the cart may be dumped by simply backing the horse
when the pivot point is above the axle journal and the forward movement of the
horse will cause the cart to resume its normal position or vice versa when the pivot
is below.
As the portion of the crank axle B to which the cart body A is secured is
below the journals or pivot pin of the said crank axle and the pivot pin of the

page_text: shafts E is above the said crank axle journal the dumping of the cart throws its
bottom forward and upwardly which greatly facilitates the dumping.
When the cart is used for wood, a tail-board I extending above the rails G is
used. In ordinary carts the upper part of the tail-board is left unsupported and
consequently sags backward under strain and also brings great strain on the
fastenings. To obviate this difficulty a bracket or support K is provided
extending above each rail G to support the upper portion of the tail-board and
adapt one arm of the lock J to engage with one of the brackets K. My corre-
spondent does not confine himself to the ordinary lock J shown nor is it necessary
that the brackets K should be made in one piece with the rods L supporting the
lower part of the tail-board I.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is,
1. A crank axle rigidly secured to the body of a cart and journalled on the
cart wheels in combination with a pair of shafts pivotted to the cart body at a
point above or below the axle journal substantially as and for the purpose
specified.
2. The combination with a tail-board extending above the rail of a bracket
arranged to support the upper part of said tail-board substantially as and for the
purpose specified.
Dated this 9th day of February 1892.
