Civil Engineer, for the Invention of "IMPROVEMENTS IN TIPPING WAGGONS."
A communication from Job von Witzleben, of Arnstadt, in the Empire of
Germany
Sealed the 23rd December 1879, and dated the 1st October 1879.
PROVISIONAL SPECIFICATION left by the said Friedrich Kuntze at the Office
of the Commissioners of Patents on the 1st October 1879.

"IMPROVEMENTS IN TIPPING WAGGONS." A communication from Job von Witzleben,
of Arnstadt, in the Empire of Germany.
The improvements relate to waggons and carts intended for tipping their contents,
said tipping having been hitherto performed by one complete lift up of the body of
the waggon or cart, and so the whole contents shot out at once. Now this Invention
consists in constructing such waggons and carts so that their tipping may be gradual
as well as sudden, by arranging the tip up body at any desired angle of tip. The
Invention is performed by hinging the body to the under carriage, furnishing the
body with a quadrant rack or racks to be operated by a pinion gearing into said
racks and placed on the underframe, said pinion being supplied with a convenient
handle for actuating it.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Friedrich Kuntze in the Great Seal Patent Office on the 30th March
1880.

"IMPROVEMENTS IN TIPPING WAGGONS." A communication from Job von Witzleben,
of Arnstadt, in the Empire of Germany.
In tipping or tilting carts, as at present constructed, the cart body is united with
the carriage frame by a turning axle, and the load is generally so arranged that its
centre of gravity is in or near the vertical plane of the turning axle, whilst a second
connection easily loosened hinders the body from tipping up during movement. If
this connection is loosened the body tilts up, either of its own accord or by some
help, and the consequence is the sudden pouring down of the whole load. It is

page_text: however frequently desired, especially for farming purposes, that the discharge should
not take place suddenly and on one and the same place, but gradually or by certain
intervals during the movement of the cart, in order to produce a certain distribution
over a larger distance or on different points. Now this Invention consists in con-
structing such waggons and carts so that their tipping may be gradual as well as
sudden, by arranging the tip up body at any desired angle of tip. The Invention
is performed by hinging the body to the under carriage, furnishing the body with a
quadrant rack or racks to be operated by a pinion gearing into said racks and placed
on the underframe, said pinion being supplied with a convenient handle for actuating
it. In the annexed Drawing is: Fig. 1, a side view of a tipping cart in its normal
state; Fig. 2, a side view of it when discharging its load; Fig. 3, a transverse section
through line a¹, 61, of Fig. 1. The box A, A, is not.invariably connected with the
carriage frame B, B, but rests on the rolls C, C', and D, D', on both sides of the
carriage-frame, and is further provided on both sides with rolls E, E. The mechanism
serving to move and tilt the box consists of the two axles a and b running in
bearings on the carriage frame, a being turned by a crank and imparting motion to
bby the spur wheels c and d, whilst the pinion i mounted on b gears into the rack
h, h, h, which is fastened to the underside of the box A, A, so as to convert the
turning motion of the crank into a shifting or tilting motion of the box. This rack
forms an angle, one side of which is straight, whilst the other is curved, as shown.
In the normal state of the box, as represented in Fig. 1, the centre of gravity of the
box with the load lies in a vertical plane behind the axle b. By turning the crank
forward the box is shifted to the right, and as soon as the pinion i arrives at the
curved part of the rack it lifts the box and causes it to turn on the axis C, C¹.
According to the length of the curved rack any elevation can be given to the box,
whilst the hooks g, g, entering under the rolls C, C, prevent the box from rolling
down. By the opposite turning of the crank the box is replaced in its normal
position between the iron fangs 8, 8', whilst the four hooks m, m¹ and n, n', catch
the rolls C, C, D, D¹, so as to insure the steadiness of the box. The hook k not
only serves to fasten the box in the state of rest, but also as a catch to prevent the
return of the elevated box by letting it catch between the wheels c and d. In order
to effect the gradual or intermittent discharge mentioned above the back wall of the
box is made inovable on hinges in the ordinary manner, and provided with a draw
rod by means of which it can be more or less opened and shut. The driver, while
holding the reins with the left hand, is thus enabled to regulate the elevation and
the discharge of the box with the right. I do not however confine myself to the
shape, size, number, aud position of the various parts shown by the Drawing, but
claim 1. The application of a rack and pinion turned by a handle for shifting the
box of a cart on its underframe and raising it to the desired height or lowering it,
substantially as described. 2. The arrangement of the trap door with draw rod p,
whereby the driver can either control the door from his seat while the cart is running
or while he is standing and operating the tilting appliance, substantially as described.
3. The application of hooks m, m2, and n, n, arranged as described, for automatically
securing the box when returning to its normal position, substantially as described.
In witness whereof, I, the said Friedrich Kuntze, have hereunto set my hand
and seal, this Twenty-fifth day of March, A.D. 1880.
