PROVISIONAL SPECIFICATION.
Improvements in Railway Tip-waggons.
I, EDWARD TENNEY BOUSFIELD, of Bedford, in the County of Bedford, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to railway or tramway waggons of that class from which the
load is discharged by tipping the body or tub.
Such waggons, as commonly made are defective in that the load is discharged too
near the waggon frame or wheels and that, unless made inconveniently high, a sufficient
angle of tip cannot be obtained to entirely empty the waggons.
According to my invention I overcome these disadvantages by constructing a waggon
so that the body or tub can be moved towards that side or end of the waggon frame
over which the load is to be discharged.
In order to bring the body or tub into this position the trunnions at each end are
fitted with rollers or wheels, or the trunnions are supported in a frame carrying rollers
or wheels, which rollers or wheels work upon, guide-ways formed on the end carrying
brackets or frames. On the guide-ways small bodies or tubs with moderate loads can
easily be pushed by hand, for bodies or tubs for carrying heavy loads mechanical power
is advantageously employed. The guide ways are fitted with fixed or movable stops-
for retaining the body or iub in the proper position for travelling and for arresting the
movement on the guide-ways.
It will be understood that when the body or tub has been moved as described it
can be tipped so that the load will be discharged clear of the waggon frame as
desired.
Sometimes instead of adapting the body or tub to run on guideways I obtain the
required movement by mounting it on a rocking frame by means of which the load can
be moved to either side so as to discharge it clear of the frame of the waggon.

Improvements in Railway Tip-waggons,
I, EDWARD TENNEY BOUSFIELD, of Bedford, in the County of Bedford, Engineer, 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 relates to railway or tramway waggons of that class from which the
load is discharged by tapping the body or tub, and generally known as tip-waggons;
the object of my said invention being to provide improved means for discharging the
load clear of the rails upon which the waggon runs by shifting the axis upon which
the body moves towards that side or end of the waggon from which the load is to be
discharged.
In the accompanying drawings-
Figure is a longitudinal section of a waggon constructed according to my
invention:
Figure 2 is a transverse section of the same; and
Figure 3 is, a view similar to figure but shewing the body in a positon for discharg-
ing the load.

page_text: Figures 4 and 5 are longitudinal and transverse-sections respectively illustrating a
modification of my invention;
and
Figures 6 and 7 are side and end views respectively illustrating another modification;
Figure 8 is a view similar to figure 7 but shewing the paris in the position which
they occupy when the body or tub is tipped:
Figures 9 and 10 are views similar to figures 7 and 8 respectively illustrating another
modification.
Similar letters of reference indicate corresponding parts in the several figures.
a indicates the under frame, and the body or tub.
As shewn in figures 1,2 and 3the bodyb is adapted to be moved upon the under frame
towards one side of the waggon, and for this purpose guide-ways ce are formed upon the
said under frame upon which slides d,d, upon the body, work. e, è are rollers projecting
slightly above the guides, for reducing the friction between the body and the guides,
which rollers are connected in pairs by shafts .. Small bodies or tubs with moderate
loads cau be easily pushed along the said guides. by hand. are stops for preventing
the tipping of the body wllen travelling aud for preventing it from being moved too
far towards the side of the waggon. As shewn these stops are fixed beneath the body
and when travelling are adapted to engage beneath one of the shafts f, as shewn in
figure 2, and when being tipped, beneath the other shaft f, as shewn in figure 3. / is
a gravity-catch for preventing the body from moving upon the under frame when
travelling.
When my improvements are applied to waggons the bodies. of which are too heavy
to be moved by hand, I provide mechanical means for moving the same; an arrange:
ment of mechanism suitable for this purpose is shown in figures 4 and 5. In these
figures the rollers c, e are represented as provided with gear-feeth, and the slides d, de
are provided with corresponding teeth to form rocks: On the shafts f. f are mounted
worm-wheels i, i, with which engage worms j, j. mounted upon a shaft carried in
suitable bearings in the under frame. With this arrangement it is obvious that, when
the shaft is rotated by a crank, the body will be caused to traverse upon the
guide-ways c, c and thai, when the stops y come into contact with the shaft 7. the
Continued rotation of the said crank will cause the tipping of the body, as indicated by
dotted lines in figure 5.
The waggon represented in figures 4 and 5, in addition to being adapted to be moved
mechanically, is also designed to discharge its load at either side, and for this purpose
it is provided with two sets of stops g. In order that one set of stops shall not interfere
with the action of the other set. the said stops are pivotted at m, m so that, when one
set is in engagement with its shaft. f. the other set will slide over the shaft, as
indicated by the dotted lines in figure 5.
Instead of adapting the body to move upon guide-ways as hereinbefore described,
1 in some cases obtain the required movement by mounting it on a rocking frame.
Such an arrangement is shewn in figures 6. 7 and 8 in which the letters an indicate two
brackets, constituting the rocking frame and supporting the body or fub between them
by means of trunnions », n. As shewn in the drawing two trunnions are placed at
each end of the tub b. Each bracket of the rocking frame is supported upon two
pius p. p carried in brackets or uprights pl. pl. upon either of which pins it can rock
to the position shewn in figure 8, the holes in the said brackets, through which the
said pins p. pass being slotted to allow of this movement.
To prevent the tub from overturning I provide on the ends of the same, pins q. 4
adapted to cuter corresponding recesses r, r on the brackets m, n.
The upper surface of each bracket n, on each side of a vertical centre line. is curved
to the arc of a circle, the centre of which is the centre of the adjaceni più 7 when in
its recess r, and at the extremities of each bracket are projections s,
With this construction it will be understood that the tub
either side has three distinct motions imparted to it, ci

upon the pius during the rocking of the rocking frame, the tub being then in the
position shewn in figure 8.
P
A modified form of rocking frame is shewn in figures 9 and 10, where the brackets
are represented as composed of metal plates, supported upon pins p, p between the
plates of divided uprights p', p'. Each bracket has two openings t, u, the former of
which has passed through it a pin for preventing the brackets from rocking too far,
and the latter serving for carrying the trunnious o, o. With this arrangement the
stops are unnecessary, as the trunnions being placed in the openings u, u are
prevented from moving too far, when the tub is tipped as shewn in figure 10.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is
1. A tip-waggon, such as herein before described, the body or tub of which before
being tipped is adapted to be moved toward that side of the waggon at which the load
is to be discharged.
2. A tip-waggon the body or tub of which is mounted upon guide-ways upon which
the tub or body may be moved (either directly by hand or by suitable gearing), towards
the side of the waggon frame on which the tub is to be tipped and the load is to be
discharged, substantially as described.
8. A tip-waggon the body or tub of which has one or more trunnions or their
equivalent at each end, the said trunnions or their equivalent being supported by frames
or brackets which are capable of movement, and which permit, a motion of the tub or
body towards the side of discharge in addition to the motion permitted by the
trunnions, so that on being tipped the load may be discharged clear of the wheels and
rails, substantially as described.
4. The manufacture and use of tip-waggons, the bodies of which are adapted to be
moved and tipped, substantially as hereinbefore described and illustrated in figures L.
2 and 3 and figures 4 and 5 of the accompanying drawings,
5. The manufacture and use of tip-waggons mounted upon rocking frames. sub-
stantially as described with reference to figures 6, 7 and 8, and figures 9 and 10 of the
accompanying drawings.
