ALFRED GEORGE MARGETSON of the City of Bristol Engineer and WILLIAM
STUDLEY HEK of the same place Foreman Wheelwright "IMPROVEMENTS IN TIP
WAGONS AND TIP CARTS
"
Our invention has reference to tip wagons and tip carts and consists in the first
place in effecting the tipping of the wagon or cart by means of a vertical screw
and in so arranging this screw that it adjusts itself to the curve in which the
wagon body moves as it is tipped. The screw. adjusts itself to the curve by its
end being made to pass through a boss forged on a horizontal spindle which spindle
works in bearings, and further a nut is fitted to the underside of the wagon
through which the screw travels which nut works in brackets with oval holes; the
screw is thus kept true to the same are as that which, the front wagon describes
when being tipped. The screw is worked by a pair of mitre wheels one attached
to the end of the screw and the other to another horizontal spindle working in
bearings which spindle terminates by the handle by which the wagon body is
tipped.
In a four wheel wagon we make the body to tip upon brackets which go round
the back axle inside the wheels and carry the hind springs. These brackets are
attached to the wagon axle and the springs to the frame of the body. The same
arrangement applies to wagons without springs..
Our invention further consists in hinging the tail board at the bottom and
connecting thereto a lever which extends along the side of the wagon and
terminates in a handle within reach of the driver so that he can by means of the
lever and from the front of the wagon unfasten the tail board and draw it close up
under the bottom of the wagon. The same lever keeps the tail board fastened up
under the bottom of the wagon till liberated again; the tail board will thus be
quite out of the way when the wagon is tipped.
The invention is applicable both to four and two wheel wagons and carts.

" IMPROVEMENTS IN TIP
Our invention has reference to tip wagons and tip carts and consists in the first
place in effecting the tipping of the wagon or cart by means of a vertical screw
and in so arranging this screw that it adjusts itself to the curve or are in which
the wagon body moves as it is tipped. The screw adjusts itself to the.curve by
its end being made to pass through a boss forged on a horizontal spindle, which
spindle works in bearings, and further a nut is fitted to the under side of the wagon
through which the screw travels, which nut works in brackets with oval or
elongated holes, the screw is thus kept true to the same arc as that which the
front of the wagon describes when being tipped. The screw is worked by a pair
of nitre wheels one attached to the end of the screw and the other to another
horizontal spindle working in bearings, which spindle terminates by the handle by
which the wagon body is tipped.
In a four wheel wagon we make the body to tip upon brackets which go round
the back axle inside the wheels and carry the hind springs. These brackets are
attached to the wagon axle and the springs to the frame of the body.
The same arrangement applies to wagons without springs.
Our invention further consists in hinging the tail board at the bottom and
connecting thereto a lever which extends along the "side of the wagon and
terminates in a handle so that the driver or man in charge can by means of the
lever and from the front of the wagon unfasten the tail board and draw it close up
under the bottom of the wagon. The same lever keeps the tail board fastened up
under the bottom of the wagon till liberated again. The tail board will thus be
quite out of the way when the wagon is tipped.
The invention is applicable both to four and two wheel wagons and carts.
The accompanying drawings illustrate our invention. Sheet 1 represents a four
wheel wagon fitted with our improvements. Figure 1 is a side clevation with the
wagon closed and Figure 2 a similar view with the wagon tipped and the tail
board open and drawn under the wagon body. Figure 3 is a back elevation of
the wagon. Figures 4 and 5 are detail views of the tipping apparatus. Sheet 2
represents a two wheel cart fitted with our tipping apparatus. Figures 6 and 7
are side elevations representing the cart untipped and tipped respectively.
Figures 8 and 9 are detail views. The same letters of reference indicate corre-
sponding parts in all the figures.
A is the vertical screw by means of which the wagon or cart body is tipped this
screw being so arranged or set that it adjusts itself to the curve or are in which
the front of the body moves while being tipped. For this purpose the lower
portion of the screw passes through a boss 6 on a horizontal spindle B' which
spindle works in bearings C C; and to the underside of the wagon body is fitted a
nut D through which the screw A travels this nut having trunnions or axes d
which work in oval or elongated holes e in brackets E on the wagon or cart body.
It will thus be seen that as the wagon or cart body is being tipped the nut D and
the spindle B gradually turn on their axes to accommodate the screw A to the curve
or arc in which the front of the body moves. The screw A is rotated by a pair of
mitre wheels F F one of which is fixed to the end of the screw A and the other to

page_text: a. horizontal spindle B which terminates just inside the boss band works in
bearings CC; to one end of the spindle B the handle X for tipping the body is
attached. In the four wheel wagon, sheet 1, the body tips upon brackets G which
go round the back axle inside the wheels and carry the hind springs as already
hereiubefore explained.
H is the tail board of the wagon; it is hinged at the bottom as shewn and has
connected to it a lever I which extends along the side of the wagon and terminates
in a handle K. L L are catches which hold the tail board. O is a bar extending
across the tail board and divided in the centre; it moves upon two bolts P P and
is held in position in the catches L L by two steel springs QQ. As the wagon is
being tipped the lever I is raised by means of its handle K (and this may be done
by the man who is turning the handle X); the lifting of the lever I releases the
bar O from the catches L L, and then by the pressure of the load and by its own
weight the tail board falls; the weight of the tail board and the momentum due
to its fall push up the lever and if pushed far enough a shoulder M thereon catches
over the bar N on the side of the wagon; or if the lever is not pushed up
sufficiently by the fall of the tail board the man in charge can pull it forward until
the shoulder M catches over the bar N. The tail board is thus fastened up under
the bottom of the wagon until liberated again.
The tail board arrangement is equally applicable to two wheel carts although
we have not shewn it applied to the cart illustrated in Sheet 2.
Having now described the nature of our said invention and in what manner the
same is to be performed we declare that we claim :-
1. Constructing tip wagons and tip carts in such manner that the tipping is
effected by means of a vertical screw so arranged or set that it adjusts itself to the.
curve or are in which the wagon or cart body moves as it is tipped substantially
as herein before described and represented in the accompanying drawings.
2. Hinging the tail board of wagons and carts at the bottom and connecting
thereto a lever which extends along the side of the wagon or cart so that the
driver or man in charge can by means of such lever unfasten the tail board and
draw it close up under the bottom of the wagon or cart body and there fasten it,
substantially as herein before described and represented in the accompanying
drawings.
In witness whereof we the said Alfred George Margetson and William Studley
Hek have hereunto set our hands and seals this fourth day of January One
thousand eight hundred and eighty four
