Improvements in Dumping Carts or Waggons.
I LEWIS STEWART BROWNING of the City of Montreal, in the District of
Montreal and Province of Quebec Dominion of Canada Waggon Builder do hereby
declare the nature of this invention to be as follows:-
This invention has for its object to facilitate the operation of dumping, the
contents of carts or waggons and also to minimize the noise hitherto caused by such
carts or waggons when in motion and especially when empty, the parts to which the
invention more particularly relates being the supporting and dumping mechanism.
The body of the cart or waggon in its normal position rests upon two pedestals
set upon the axle which passes through them and is suitably secured in place.
These pedestals are formed in two parts one sliding within the other and enclosing
a spring.
The shafts are set into or upon these pedestals which are pivotted at their rear
side to the bottom of the cart or waggon the pivot pin projecting on either side and
having levers mounted upon it, the long ends of which levers are pivotted to the
tail board, the short ends being curved and pivotted to the pedestals by pins passing
through slots therein.
To the body of the cart or waggon and the pedestals springs are connected.
To the upper edge of the tail-board may be pivotted levers the said levers being
pirotted at their other ends to the bottom of the cart or waggon.
A spring locking device holds the cart or waggon down upon the shafts and when
this is released the cart or waggon can be easily thrown over by the driver without.
leaving his seat on the shaft, the springs interposed between the cart or waggon
and the pedestals helping to draw it down and preventing jar.
The levers above mentioned serve, when the cart or waggon is tipped, to lift the
tail board upwards and forwards allowing the contents to be dumped.
When the cart or waggon is relieved from the weight of the contents the springs
will assist in restoring it to its normal position, the tail board being automatically
and simultaneously replaced by the action of the levers.
The invention as far as regards the dumping mechanism is equally applicable to
what are termed tail-less carts in which there is no tail board but the rear end
slopes downwards and forwards or is rounded. in that direction. With this con-
struction the side levers are not needed.

Improvements in Dumping Carts or Waggons.
I LEWIS STEWART BROWNING of the City of Montreal in the District of
Montreal and Province of Quebec, Dominion of Canada, Wa aggon Builder 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 :-
My invention has for its object to provide a dumping waggon or cart with means
whereby the contents thereof may be dumped without the driver being required to
leave his seat and whereby rattling and jarring noises when the vehicle is in motion
are prevented or minimized.

page_text: My invention relates particularly to those parts connected with the supporting.
and dumping mechanism. The body of the cart or waggon when in its normal
position rests upon pedestals mounted upon the axle, which passes through the said
pedestals and is secured thereto in a manner to admit of the body rising. and falling
for which purpose each pedestal is formed in two parts arranged to slide one within
the other, springs being provided in the pedestals which admit of the body of the
vehicle yielding and also prevent jarring noise when the vehicle is in motion. The
outer part of each pedestal is formed with a socket to receive the shafts and also
with an ear or lug corresponding to similar ears or lugs projecting from the body of
the cart or waggon the said ears or lugs having holes therein to receive pins or
bolts forming the axis on which the body is capable of turning. These pins or
bolts project on each side of the body and on each is secured a double armed lever,
the long arm of each lever being connected to the tail-board and the short arm
being slotted to receive a pin projecting from the pedestal. Helical springs are
interposed between the rear sides of the pedestals and the under side or bottom of
the body to assist the body in its tilting movements. The tail-board is connected
to the body by rods or arms pivoted thereto at both ends. A spring locking device
is provided to hold the body in its normal position upon the shafts, and when this
locking device is released the body can be easily thrown over by the driver.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 is a side view of a dumping cart constructed according to my invention
the body being shewn locked in its normal position, the wheels being omitted for
the sake of clearness ;
Figure 2 is a part rear view of the same;
Figure 3 a side view of the cart in its position when dumped, the outer shell of
the pedestal being broken away to shew the interior;
Figure 4 is a detail of one of the pedestals drawn to a larger scale;
Figure 5 is a detail of the locking device and
Figure 6 is a side elevation of part of a tail-less, dumping cart showing the
application of the helical springs for returning the body to its normal position after
dumping.
The body A of the cart, is usually made of metal, but it may if desired be made
partly of wood and partly of metal. A is the tail-board which when the body A
is in its normal position rests within a turned-up ledge a at the back part of
the body.
B are two pedestals mounted on and near the opposite ends of the axle C. Each
of these pedestals consists (as shewn in Figure 4) of an inner shell b, containing a
spring D and an outside shell 6', strengthened or supported on the exterior by ribs
or the like as shewn at 6' 6' so as to form a lateral bearing for the axle C and to
sustain the pedestal.
A plate is arranged beneath the axle it being bolted to the pedestal to retain
the axle and the inside shell b in place.
In the upper forward side of each pedestal a socket E is provided to receive the
inner ends of, the shafts F, which are secured in place by bolts f and ridges e
extending across the bottom of the sockets and engaging recesses in the shafts.
On each of the sockets E is formed, as shown in Figures 2 and 4, an ear or
projection G, having a hole G₁ therein for the reception of a bolt or pivot-
spindle H, on which the body A turns, the pivot-point. being as nearly as possible
over the point of support. The bolt or spindle H passes through corresponding
eyes G on the under side of the body A. and projects from the side of the body so
as to form the pivot of a lever K which is mounted thereon. The long arm k of
this lever is connected at g to the tail-board A' somewhat below its upper edge, the
short arm being curved or having a curved slot therein struck from the pivot-
point H, as shown at ³ to receive a pin l, projecting from the pedestal B.

page_text: M are plates secured to the under side of the body A between which and the
rear of the pedestals B are interposed curved coiled springs N. In the case of a
dumping cart without a tail-board and in which the rear portion of the body is
tapered upward the plate for one end of the spring is arranged on the side of the
cart body as shown at M' in Figure 6, the other ends of the spring being secured
to a plate M' attached to the shaft F.
O are levers or arms pivoted at one end to the plates M and at their other
ends to the tail-board A¹.
The locking device I prefer to employ for holding the body A. in its normal
position is shown in Figure 5, and consists of a spring bolt P₁ caused to engage a
projection P secured to the front of the body A. The bolt P' is mounted on the
cross-bar F which connects the two shafts of the cart together and is carried on a
rod R partially enclosed by a sleeve & secured to the said cross-bar F¹. The
rod R carrying the bolt P' is surrounded by a spring r which normally forces the
bolt forward to engage the projection P. This rod R passes through the end of
the sleeve Q and is turned up at the end as shewn at R¹ to form a handle by means
of which the bolt may be disengaged from the projection P when required.
Although this device will be found very efficient for the purpose I do not confine
myself to its use, as any equivalent mechanism may be employed.
It will be apparent from the position of the spring-pedestals B being directly
between the axle, on the one hand, and the body A shafts F, and the locking device
(which constitute a rigid whole) on the other hand that all rattling is avoided.
The dumping operation is effected as follows:-
The driver, without moving from his seat may by a slight pressure of his foot or
otherwise on the bar R withdraw the bolt P out of engagement with the stop P¹,
thus leaving the body A free to be moved by a slight push so as to turn on the
pivots H and cause the load to fall towards the rear, the springs N being drawn by
the tilting of the body A over the centre helping to lower the rear end of the
body, the said springs N also acting as compression-springs prevent jars. As
the body tilts on the pivots H the levers K also turn on the said pivot until
the opposite ends of the slots come into contact with the pins as shown in
Figure 3, in which position the lever and the pin will remain. As the distance
between the pivot-point H, and the point of attachment of the lever K to the
tail-board A, must be invariable, the further depression of the rear of the cart
will, by means of the levers O, throw the tail-board A' upward and forward, until
it assumes the position shown in Figure 3 in which position the contents of the cart
are dumped. When the body is relieved from the weight of the contents, the
expansive action of the springs N N will raise the rear end of the body, and
thereby, through the arms OO, bring the tail-board backward and downward till it
falls into place as shown by dotted lines in Figure 3, and when in this position the
cart may be loaded from the rear. When the cart is being loaded the body will,
either by itself or with a slight effort on the part of the driver, drop into position
and be secured there by the self locking bolt P' engaging with the stop P.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a dumping cart or waggon the combination, with the body shafts and axle,
