"IMPROVEMENTS IN
My Invention relates to certain improvements in waggons or lorries, by which
improvements waggons or lorries can be tipped or kecked for the purpose of dis-
charging their load, and for other purposes.
In constructing a waggon or lorrey according to my Invention I provide the
underside of the platform of the waggon or lorrey with horizontal guides which
receive guide blocks which carry the platform, and which are connected to the
springs and thereby to the bed or axle frame, or connected to the bed or axle frame
direct. The platform is further provided on its under side with horizontal guides,
into which takes a horizontal cross bar extending from two projecting beams or
arms, the other ends of which are attached to the top of the under carriage or front
running gear. The front of the platform is provided with on its under side two
inclined planes, which form stops, and a locking chain for locking the platform
when in a horizontal position to the under carriage or front running gear. The
bed or rear axle frame is also provided with a chain attachment to the back of the
platform, and with chains connected with the platform in front of the rear
wheels.
In operation to tip or keck a waggon or lorrey constructed according to my Inven-
tion the locking gear in the front is disengaged, and also the locking chain and gear
from the bed or rear axle frame at the back of the platform. The rear wheels are
then scotched behind, and by the horse or other means the front wheels and under
carriage are backed. The result is that the cross bars on the projecting beams from
the under carriage moves backwards in the horizontal guides, and the platform also
moves backwards on the horizontal guides in connection with the springs or axle
frame. The rear wheels are thus brought to a position at, or near, or past the centre

page_text: of gravity of the platform. The result is that the platform tips or kecks up and
discharges its load. To regain the horizontal position after discharging the rear
wheels are scotched, and by the horse or otherwise the under carriage and front
wheels are drawn forward. The horizontal bar from the projecting beams slides
forward in its guides, and then pulls the platform into a horizontal position, and
then draws the platform forward in its guides until the rear wheels reassume their
position at the rear of the platform. The rear wheels are then scotched behind,
and the rear chain fastened to the platform. The under carriage is then backed up
and assumes its correct position at the front of the platform, and is secured by the
locking gear.
The principle of action upon which my Invention is based is that of moving the
platform in a rear direction and bringing the rear wheels into a position near, over,
or past the centre of gravity of the platform, this being accomplished by the use of
horizontal guides or their equivalent under the platform, and by bringing the front
and rear wheels close together.

the said Thomas Monk in the Great Seal Patent Office on the 24th February
1880.

AND RELATING TO WAGGONS OR LORRIES."
'IMPROVEMENTS IN
My Invention relates to certain improvements in waggons or lorries, by which
improvements waggons or lorries can be tipped or kecked for the purpose of dis-
charging their load, and for other purposes.
In constructing a waggon or lorrey according to my Invention I provide the
underside of the platform of the waggon or lorrey with horizontal guides which
receive guide blocks which carry the platform, and which are connected to the
springs and thereby to the bed or axle frame, or connected to the bed or axle frame
direct. The platform is further provided on its underside with guides, into which
takes a horizontal cross bar extending from two projecting beams or arms, the other
ends of which are attached to the top of the under carriage or front running gear.
The front of the platform is provided with on its underside two inclined planes,
which form stops, and a locking chain, or gear for locking the platform when in a
horizontal position to the under carriage or front running gear. The bed or rear
axle frame is also provided with a chain attachment to the back of the platform,
and with chains connected with the platform in front of the rear wheels.
In operation to tip or keck a waggon or lorrey constructed according to my
Invention the locking gear in the front is disengaged, and also the locking chain
and gear from the bed or rear axle frame at the back of the platform. The rear
wheels are then scotched behind, and by the horse or other means the front wheels
and under carriage are backed. The result is that the cross bar on the projecting
beams from the under carriage moves backwards in the guides, and the platform

page_text: A is the platform of the waggon or lorrey, which is provided with the horizontal
guides B, B, which receive the guide blocks C, C, C, C, provided with antifriction
rollers D (for detail see Figure 4). The guide blocks Care attached to the springs E,
and carry the platform A. The springs E are connected in the usual manner to a
bed or axle frame F, which is carried by the rear wheels H. The platform A is
hinged or pivotted at J, J, to two projecting beams or arms K, K, the other ends
of which are attached to the top of the under carriage or front running gear L.
The front of the platform A is provided with a provision M, which receives the bolt
of a locking lever N fitted on the front of the under carriage L. This locking
lever N locks the platform A to the under carriage L when in a horizontal position,
as shown at Figure 1. The lever N is automatically operated by the rod P, which
is worked by the lever Q, which is operated by the pin R when the rear wheels H
come to the front by the sliding back of the platform A; the lever N is kept
unlocked by the spring catch S. T, T, and U, U, are stops to regulate the travel of
the platform on the rear wheels; V (for detail see Figure 5) is a stop rod for keeping
the rear wheels H in their place when the platform A is in a horizontal position, as
shown at Figure 1. Upon the withdrawal of the stop rod V, so that the pins W, W,
are clear of the guides B, B, the platform A can be slid back upon the guide blocks
C, C, C, C, when required to be kecked; such sliding back of the platform A causes
the pin R to actuate the levers Q and withdraw the locking lever N, so that the
waggon or lorrey can be kecked.

page_text: In operation to tip or keck the platform A of the waggon or lorrey the rear
wheels H are scotched behind, the stop bar V is withdrawn, and by the horse or
other means the platform A and the under carriage L and front wheels are run
back, the guides B, B, of the platform A sliding over the guide blocks C, C, C, C,
until the centre of gravity of the platform A with its load comes over or behind the
axle of the rear wheels H. The locking lever N having automatically released the
front of the platform A from the under carriage L, as before described, the platform
A then tips up on the pivots or trunnions J, J, on the beams K, K, as shown at
Figure 2. To regain the horizontal position of the platform A after the load is
discharged the rear wheels are scotched in front. The front carriage L and the
platform A are drawn forward, the platform A again sliding over the guide blocks
C, C, C, C, until the platform A resumes the horizontal position, when the stop
bar V is replaced and the platform A locked in front of the under carriage L by
the lever N.
.
Although in the Drawings and the beforegoing lettered description I have illus-
trated a waggon or lorrey slightly differing in detail from the description in the
first part of this Specification, I would have it understood that one arrangement is
a mere modification of the other, and in no way affects or alters the system of
construction of waggons or lorreys according to my Invention. In the former
instance I use chains as stops, and I connect the beams K, K, to the platform A by
a horizontal cross bar provided with guide blocks, the ends of the cross bar in two
guides on the underside of the platform.
Having now described and ascertained the nature, object, and purposes of my
Invention, and shown, how the same may be carried out into practical effect, what I
claim as my Invention.is,―
Firstly. Constructing waggons or lorries so that the platform can be moved in a
rear direction over the bed or rear axle and wheels until the centre of gravity of
the platform is brought into a position near, over, or past the axle of the rear
wheels, substantially as herein before described and illustrated and for the purposes
set forth.
Secondly. The construction and arrangement of waggons and lorries, as herein
before described and as illustrated in the Drawings hereunto annexed for the purposes
specified.
Thirdly. The combination and arrangement of parts (for enabling waggons or
lorries to be tipped or kecked), constructed and operating substantially in the
manner and for the purposes set forth.
In witness whereof, I, the said Thomas Monk, have hereunto set my hand and
seal, this Twentieth day of February, in the year of our Lord One thousand
eight hundred and eighty.
