Improved Tipping Wagon.
We, WALTER GRIFFITHS, of the Waverley Café, High Northgate, Darlington,
in the County of Durham, Works Manager, and FRANK WILLIAM CHARLES
HAWKER, of 74, Westmoreland Street, Darlington, in the County of Durham,
Draughtsman, 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:-
Our invention has for its object to provide wagons with means whereby the
bodies can be tipped obliquely in any outward direction, and the contents be dis-
charged.
We use a bar attached to the top centre of the underframe of the wagon, and
pivoted at its centre so that it can revolve on its centre in any horizontal direction.
To each end of the pivoted bar are attached rollers which are free to revolve on
the pivoted bar on their own centres, and also free to revolve round the pivoted
centre in any horizontal direction with the pivoted bar.
Also to each end of the pivoted bar are attached the bearances of the body,
which bearances are firmly attached to the body and free to revolve on the pivoted
bar until the body touches the underframe, and also to revolve round the pivoted
centre in any horizontal direction with the pivoted bar.
To the back part of the body is firmly attached a roller free to revolve on its
own centre, and also to revolve round the pivoted centre in any horizontal direction
with the body. The roller firmly attached to the back part of the body also
serves to keep the body in a horizontal position.
The body can be tipped obliquely in the required outward direction by revolving
it on the rollers round the pivoted centre until the front part faces the required
outward direction, and by raising the back part whereby the front part is depressed
until it touches the underframe, the body of the wagon is made to occupy an
oblique or slanting position whereby the contents are discharged.
In order that our invention may be properly understood we will proceed to
describe it in detail reference being had to the accompanying drawings in which
similar letters refer to similar parts throughout, of course with the understanding
that we do not confine ourselves to any particular make or size, as it may be
varied without departing from the novelty of our invention.
Figure 1, Sheet 1, is a longitudinal section, and Figure 2, Sheet 1 is a cross
section of a wagon. Figure 3, Sheet 2, is part plan of the underframe with the
body removed and showing the rollers.
A is a bar pivoted at its centre B, C and C¹ are rollers attached to the pivoted
bar A. D and D₁ are the body bearances firmly attached to the body E and free
to revolve on the pivoted bar A until the body E touches the underframe K. F is
a roller firmly attached to the back part of the body, and free to revolve on its
centre G. Hand H¹ are pins which fit into the sockets J and J¹, J², J³, J*, J³
hrough the pivoted bar A which prevents the pivoted bar A from revolving when
required. K is the underframe. L is a wearing plate firmly attached to the

page_text: underframe of the wagon. M and M¹ are the wheels, and N and N¹ are the axles.
U is a fastener attached to the body E and the underframe K to prevent the body
from tipping when required.
When the body is required to be tipped obliquely in any outward direction it
is revolved round the pivoted centre B on the rollers, C, C₁ and in a horizontal
direction until the front part P is facing the required direction. The rollers C
and C and the body bearances D and D₁ are kept equi-distant and in their proper
position from the pivoted centre B by the pivoted bar A with which they revolve
round B.
Having revolved the body E so that the front part P faces the required direction
the fastener O is unloosed, the back part Q is raised,, and the front part P is
depressed until it touches the underframe K by partially revolving on the pivoted
bar A, and the body E is made to take an oblique or slanting position in an outward
direction and the contents are discharged.
Figure 2, Sheet 1 shows the body E ready for tipping in the direction R, and E'
shows the position of the body E when tipped obliquely in that direction.
Figure 1, Sheet 1 at E shows the position of the body E after it has been
partially revolved and afterwards tipped obliquely in the direction S.
By revolving the body E the required distance on the rollers C, C and F it
can also be tipped obliquely in the directions T and U or any other outward
direction.
When the body E has been placed in the required direction for tipping obliquely
it can be prevented from turning round on the pivoted centre B by the pins H
and H which pass through the pivoted bar A into the sockets J and J¹ or into
other sockets which the pivoted bar A may happen to be over, or the body may be
prevented from turning round by some other suitable method.
The body E is prevented from tipping obliquely by the fastener or by some
other suitable method.
.
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;
-
1. In connection with wagons, a body which can be revolved horizontally on
rollers in any direction round a centre, and when required be tipped obliquely in
any outward direction as herein before described..
2. The whole arrangement and combination of parts for the aforesaid purpose
as illustrated in Figures 1 and 2, Sheet 1 and Figure 3, Sheet 2 of the accompany-
ing drawings.
Dated this Third day of April 1899.
