We EDWIN ROBERTS and HENRY ROBERTS of Deanshanger, in the County of
Northampton, Engineers and Ironfounders do hereby declare the nature of our
invention for IMPROVEMENTS IN APPARATUS FOR BALANCING AND TIPPING CARTS
AND THE LIKE and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The present Invention is an Apparatus fixed on the front of any cart wagon or
lorry &c to which it is applied, for the purpose of being able more readilly to
balance adjust or tip the load than is possible by any existing plan or system and
consists as follows.
b
The apparatus consists of a rack, worm and cog wheel placed in the following
manner; we place the rack by preference upon the shafts or under frame work of
the cart, wagon or lorry, and a worm and cog wheel upon the body of the same, we
also reserve to ourselves the right of placing the rack upon the body of the cart or
other vehicle, and the worm and cog wheel upon the shafts or under frame of the
cart, &c thus simply reversing the order of their position.
The worm is thrown in and out of gear by a handle at the side of the cart, the
spindle of the same working in an eccentric barrel having a handle at one end,
which upon being turned half-way round draws the worm out of gear of the cog
wheel, allowing it to run down free of the handle, and by returning the handle to
its former position the worm is again put into gear with the cog wheel.
We also fix or centre the cog wheel upon a pin or stud, the latter being attached
to an iron bar or lever at the outer end of which is formed a handle and small pin
attached to a short chain for safety; this handle being placed at the opposite side
of the cart to that of the handle connected with the worm, the Apparatus may
therefore be operated by this lever or draw-bar by pushing the same in and out,
which simply takes the cog-wheel out of gear with the rack and allows the cart to
tip instantaneously and run down quite free and independently of the handles on
the opposite side of the cart, wagon, &c.

page_text: In the operation of balancing and adjusting the weight or load we turn the worm
by the handle at the side of the cart to any desired position, also by turning the
handle attached to and forming part of the eccentric barrel half-way round a cart
may be tipped at once and in any position, without the balancing handle being
touched or the worm operated in any way which is a great advantage; the same
result is obtained when on the opposite side of the cart by means of the horizontal
lever, as by pushing the same in the cog wheel is thrown out of gear with the rack
and the cart tipped:
For the purpose of making our Invention clear we now refer to the drawings
Figs. I and II, fig. I being a detailed drawing of the apparatus, whilst fig. II shows 1
its application to an ordinary two wheeled cart for contractors and agricultural
purposes, the Invention being equally applicable to wagons, lorrys &c.
In Figs. I and IIa is the rack pivotted at a¹ to the shafts or under frame-work of
the cart, b is the cog-wheel and c the worm worked by the handle c¹; these latter
(the cog wheel b and the worm c) with the spindles and handles d¹ and c¹) being
placed on the upper portion or body of the cart h, h, are moveable with the body of
the cart h, whenever the apparatus is operated; it will also be noticed that the
worm and spindle c is placed eccentrically inside an iron pipe or barrel d, and by
means of the handle d, the barrel d on being turned half way round, the worm c
is thereby thrown out of gear with the pinion or cog-wheel b, and thus the load is
tipped; again on the opposite side of the cart, we effect the tipping as readilly from
that position, as occasionally it is more convenient to be able to tip from both sides
of a cart; this is effected as follows,-the cog wheel b is centred on a stud or pin f,
this stud being fixed in or connected to a lever f', so that by pushing in the
handle f, first having withdrawn the chain-pin f³, the cog-wheel b is thrown out
of gear with the rack a, and the cart thus tipped from the opposite side to that on
which it is operated when the tipping is effected by means of the worm c.
For purposes of balancing or adjusting the load so as to take any undue weight
from off the back of the horse, this is carried out with the greatest ease and
precision by simply turning the worm-wheel handle c¹ until the cart is raised to the
required position by means of the worm, wheel and rack, which are shown at b, c
and a, in Fig. I, when without any further manipulation or adjustment the load
remains in the desired position.

The eccentric barrel d, already referred to is carried in bearings at e, e, these
latter being attached as previously described to the upper part or body of the cart
and are moveable with the same, that is with the arrangement as shewn in Fig. II
viz, with the rack fixed to the shafts or under frame work of the cart; in some
instances however we might prefer with this same apparatus and combination of
rack cog-wheel and worm as now described, to fix the rack at its upper end to the
body of the cart, the rack a would then be moveable with the body of the cart, all
the other parts of the apparatus being in that case, fixed to the shafts or under-
frame g instead of to the body of the cart h, h.
The worm e and the cog-wheel b are protected from dust, grit, sand, etc by an
iron casing as at i, i, Fig. I, which would also extend up round the rack a.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1st. The combination of worm, cog-wheel and rack, and operating the same by
means of the eccentric barrel, and the horizontal lever respectively, and, as shewn
in the annexed Drawings.
t
2ndly. That by the arrangement now described we are able by means of the
worm to tip any cart, etc, instantaneously and that too quite independently of the
balancing portion of the apparatus.
3rdly. Also taking the cog-wheel out of gear from the rack in the manner

page_text: 4thly. That we claim the right to fix or pivot the rack from either its top
or bottom end, or which is the same thing viz to attach it either to the upper
body of the cart, or to the under-frame or shafts as circumstances may require,
and
Lastly. That our Invention as now described and set forth is equally applicable
to carts, wagons, lorrys, and similar conveyances for ordinary contractors and
agricultural purposes.
