Year: 1884

page_text: I THOMAS CHARLES SARGEANT, of Stowe, Weedon in the County of Northampton
Farmer and Engineer do hereby declare the nature of my Invention for
A " FOLDING" APPARATUS FOR TIPPING BALANCING AND FASTENING CARTS AND
VEHICLES to be as follows:-
This is an Invention which permits of a cart being tipped instantaneously by the
apparatus unfolding hinge-like upon three centres or joints. The cart can be set at,
perfect balance in coming down hill so that no weight is thrown upon the horse's
back. The apparatus is retained in its folded position by means of a crank & hook
coupling, which forms the fastening. To the shaft stay is bolted the bracket A
having holes or bearings to carry the worm-wheel spindle C. The bracket A is
also provided with abutments which form part of the fastening to be hereafter
described. To the worm wheel spindle is hinged or jointed the frame B. The
worm-wheel working between two arms on the frame which form abutments for
the said worm wheel. The frame is provided with bearings for one end of the two
wheels D. D. The other side of the wheels being carried by corresponding
bearings in the frame cover. The frame is provided with a slot which forms a
guide for a slide block which is made fast to an endless chain which works on the
two rolers before described. To the slide block is hinged one end of the
connecting-rod; the other end of the said rod being jointed in the bracket A₁.
which is bolted to the cart frame as shown in Drawing. To the shaft stay are
bolted small bearings which cary a cranked iron which is kept in position shown
in Drawing by a spring or weight. The frame is provided with a hook in which
this crank works, forming the fastening. The end of this crank spindle is bent
opposite or nearly so to the crank.
Now by raising this bent end the crank releases its hold upon the hook or claw
of the frame B. by so doing the cart is free to tip as the apparatus unfolds hinge
like upon the three centres C. C. C.. and close or fold again as the cart is put in
travelling position. Thus the cart can be tipped instantaneously. By turning a
handle on the worm wheel spindle motion is given to the chain wheels, causing the
slide block to which one end of the connecting rod is jointed to travel up the slot
and by so doing pushes or tips the cart up by degrees. When the slide block has
travelled to the top of the slot and it is required to tip the cart still more the crank
fastening is released and the apparatus unfolds as before described on the three.

page_text: centres, the handle is then turned to the left and the slide block again travels the
length of the slot until the apparatus is in the unfolded position as before described
when the cart is completley tipped.
I am well aware that this apparatus can be made to work with equal results by
substituting a screw and bevil wheels in place of the endless chain and worm
wheel gear, but such an Invention I should consider an infringement of my Patent
rights. It may suffice here to take the one working with a chain for an, example.
The Drawing represents a section of the apparatus in traveling position and
the dotted line represents position of apparatus when the cart is being tipped
instantainously.

page_text: I THOMAS CHARLES SARGEANT of Stowe Weedon in the County of Northampton-
shire Farmer and Engineer do hereby declare the nature of my Invention for
"A "FOLDING" APPARATUS FOR TIPPING BALANCING AND FASTENING CARTS AND
VEHICLES" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
--
This is an Invention which permits of a cart being tippped instantaneously by
the apparatus unfolding upon three centres or joints. A cart can be set at perfect
balance in coming down hill so that no weight is thrown upon the horse's back.
The apparatus is retained in its folded position by means of a crank and hook
coupling which forms the fastening.
In carrying out my Invention I affix to the shaft stay of a cart or wagon a
bracket and to this bracket is hinged a tubular or box frame or casing which
usually hangs down vertically against the shaft stay and is confined to the latter by
a cranked rod or link which takes over a hook or catch on the frame or casing.
Through the interior of the frame or casing is arranged an endless chain or by
preference a screw (as herein before mentioned in my Provisional Specification) and
on this endless chain or screw works a nut projecting through a slot in the frame
or casing where it is jointed to one end of a connecting rod the other end of which
is jointed to a bracket on the cart frame. On the rotation of the endless chain or
screw by worm and wheel or other suitable gearing the nut is moved in either
direction along the slot and so more or less balances the cart to any desired extent
when coming down hill-When it is required to suddenly or instantaneously tip
the cart the cranked rod or link is released from the hook or catch on the frame or
casing and the latter is free to move when the apparatus being acted upon by the
weight of the cart and its contents is vibrated or unfolded on its three hinges or
joints until the cart is completely tipped and emptied of its contents-The
apparatus is then again brought to its normal position and fastened therein by
the cranked rod or link as before.
And in order that my said Invention may be well understood I shall now
proceed particularly to describe the same reference being made to the accompanying
Sheet of Drawings like letters of reference indicating corresponding parts in all the
Figures.
Figure 1 is a side elevation of my improved tipping and balancing apparatus
Figure 2 a section and Figure 3 a diagram thereof shewing the position of
apparatus when the cart is fully tipped.
A represents the shaft stay of a cart or wagon to which stay at the middle or
other convenient part is secured a bracket B made in halves bolted together_as
shewn (or otherwise)-Between the cheeks or sides of the bracket B is arranged a
tubular or box frame or casing C formed at one end with a circular, rectangular or
other suitably shaped recess C³ (closed or not by a cover) on the two opposite sides
of which external thereto are trunnions E by which the frame or casing CƠ¹ is
hinged to the bracket B.-The frame or casing C C¹ usually hangs down vertically
against the shaft stay A to which it is confined by a cranked rod or link F which
radiates from bearings G secured to the shaft stay A and takes over a book or
catch H on the arm or casing C C.-I is a spring (or weight) for normally keeping
the cranked rod or link F engaged with the hook or catch H.-Longitudinally
through the interior of the frame or casing C C¹ passes a screw J (hereinbefore
mentioned in my Provisional Specification and which I use in preference to the
endless chain therein more fully described) which may be rotated by the worm
and worm wheel K K'-or by bevil wheel and pinion or by any other suitable

page_text: gearing On the screw J works a nut L which projects through a slot M in rear of
the frame or casing C and is jointed at N to one end of a connecting rod O the
other end of which is jointed at P to a bracket Q on the cart frame.-Or if
desired the nut L may project through two slots (one at each side of the frame or
casing C) and be jointed by means of two parallel connecting rods to the bracket
on the cart frame for the purpose of bringing the latter directly over or in line
with the frame or casing C.
On the rotation of the screw J the nut L is constrained to travel thereon in
either direction and acting through the medium of the connecting rod O more or
less balances the cart to any desired extent in coming down hill so that no weight
will be thrown upon the horse. When it is required to tip the cart or wagon
instantaneously to its full extent the cranked rod or link F is released from the
hook or catch H on the frame or casing C C¹ and the latter is free to move when
the weight of the cart and its contents pulling upon the connecting rod O the
whole apparatus is extended or unfolded on its three hinges or joints E N and P
until the cart is completely tipped as shewn in Figure 3 and emptied of its contents
when the apparatus is again folded or brought with the cart to its original position
as in Figures 1 and 2 and fastened therein by the cranked rod or link F as before
described.
Figure represents my Invention adapted to the use of an endless chain S as
described in my said Provisional Specification in lieu of the screw J-or I may use
any other equivalent device in lieu of the screw J or endless chain S for gradually
balancing the cart without departing from my Invention.
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,
1. The application and use to a cart or wagon of a bracket to which is hinged
'or jointed a tubular or box frame or casing containing a screw, or endless chain
(or other device) rotated by suitable gearing in combination with a nut and with
a connecting rod jointed to the nut and to the cart frame for balancing the body
of the cart or wagon substantially as herein before described and illustrated by
the accompanying Drawing.
2. The combination of a cranked rod or link mounted in suitable bearings with
a hook or catch on the tubular or box frame or casing for releasing and allowing
the latter with its combined apparatus to be unfolded on its three hinges or joints
thereby instantaneously tipping the cart or wagon, and for refastening the cart or
wagon substantially as hereinbefore described and illustrated by the accompanying
Drawing.
