PROVISIONAL SPECIFICATION.
Improved Tipping Gear and Under Framing, applicable to Road
Vans and Wagons.
I, CALEB DAVIS, of Ladybellegate, Gloucester, Carriage Builder, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improved arrangement of gear, or method of tipping
wagons, vans, or carts from the side, with means for retaining the tipping angle, or
for adjusting it, to suit the discharge of the material, or to suit the position at
which the contents have to be shot.
To carry this invention into practice, I apply to the under frame of a vehicle, a
set of gear operable by a winch handle which is removable and capable of being
temporarily hung to side supports.
The gear of the under frame is composed of mitre wheels and worm for giving
motion to a spur wheel in counection with a suspended rack of the body frame,
said rack being free to adjust itself to any desired angle by riding within or
against guide rolls of the under frame.
The under frame is so constructed that the upper, or body frame has a fair
sitting upon it and guided by it for the tipping operation, the upper or body being
pivoted on a cross bar or axle which passes through the ends of the longitudinal
lower frame. The tail board is releasable by an action on a side lever.
One of the advantages of my invention is, the body can be set at any angle, or
be brought back to any angle by turning the gear for the discharge of the load at
once, or at intervals at the same or at different spots.

Improved Tipping Gear and Under Framing, applicable to Road
Vans and Wagons.
I, CALEB DAVIS, of Ladybellegate, Gloucester, Carriage Builder, 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:-
This invention relates to improved arrangement of gear, or method of tipping
wagons, vans, or carts from the side, with means for retaining the tipping angle, or
for adjusting it, to suit the discharge of the material, or to suit the position at
which the contents have to be shot.
To carry this invention into practice, I apply to the under frame of a vehicle a
set of gear operable by a winch handle which is removable and capable of being
temporarily hung to side supports.
The gear of the under frame is composed of mitre wheels and worm for giving

page_text: motion to a spur wheel in connection with a suspended rack of the body frame,
said rack being free to adjust itself to any desired angle by riding within or against
guide rolls of the under frame.
The under frame is so constructed that the upper or body frame has a fair
sitting upon it and guided by it for the tipping operation, the upper or body being.
pivoted on a cross bar or axle which passes through the ends of the longitudinal
lower frame. The tail board is releasable by an action on a side lever.
One of the advantages of my invention is, the body can be set at any angle, or
.be brought back to any angle by turning the gear for the discharge of the load at
once, or at intervals at the same or at different spots.
My invention is illustrated on the annexed two sheets of drawings, in which at
Figure 1 show a tip wagon in side elevation, as for travelling, the body being
down and resting upon the lower or under frame which is of less width than the
body.
Figure 2 is an elevation of the same wagon body tipped, the prepondering
weight being in front of the pivot shaft, bar, or axle, and held in an elevated
position subject to adjustment as to angle by the gear hereafter explained, and
which is represented in Figures 1 and 2, and also in the end view, Figure 3, this
showing the under frame timbers in section.
Figure 4 plan view of gearing.
The gear is composed of a shaft A mounted in bracket bearings B below the
under frame C, this shaft has a square end for a winch handle D to be fitted on
when required, or it might be a hand wheel, otherwise said handle can when
removed be looped on to the stud E and within the bar F, as shown in Figure 1.
The shaft A carries a bevil pinion G in gear with a bevil wheel H on a vertical
shaft J stepped in the bracket B and into a socket eye of a cross support (not
shown) of the under frame, said vertical shaft J has a worm K keyed to it, in gear
with and for operating the worm wheel L on the supplementary shaft M fitted in
suitable bearings of the bracket B, or it may be by another bracket or socket on
the under frame C. -N is a spur or lantern pinion on the supplementary shaft in
gear with a toothed bar P hanging below the body Q from the pin R, said toothed
rack bar P is curved in its length to enable it to accommodate itself to the angle it
may assume while travelling on the pinion N in the raising and lowering operation,
the teeth of the rack bar being kept in touch with the pinion N by the roller S.
The body sits when down, as at Figure 1, on the under frame C which is
composed of longitudinal timbers with stays to make it rigid, the front part being
provided with transom rings or plates and a perch bolt and forecarriage to enable
the front wheels to be turned for locking purposes.
The rear of the body Q also has a bearing upon the under frame C and is held
in position by a cross bar or axle T which passes through the longitudinal timbers
of both the body Q and the under frame C where it acts as the pivot on which
the body is tilted, as seen at Figure 2.
The view Figure 2 by the length of the rack bar P indicates that the tilt
position can be varied for shooting the material from the body according to the
nature of the contents.
U is a lever pivoted at V for lifting the latch W of the tailboard X, this being
hinged from the top of the body to open outwards from the bottom, the latch being
otherwise secured by hand, or made to drop and secure itself automatically when
the tailboard is closed, or when it closes itself on the return of the body for a
reloading.
The arrangement of the gear is such that the worm forms a stop to hold the
body in a tilted position and it cannot move unless the hand shaft A be turned.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what 1
claim is :-
:―
1. The gear arranged in the manner shown. as an appendage to a tip wagon, and

page_text: as a means for raising, lowering, and fixing the angle of tip to the Douy m
underframe, as set forth.
2. Constructing the under frames of tip wagons and like tipping vehicles, of
less width than the body frames to enable the body frames to sit upon and be
guided by said under frames as described and substantially as represented by the
awings.
