Improvements in Depositing Apparatus to be Used in the Con-
struction of Harbour, Dock, and Quay Walls, Breakwaters,
Piers, and like Works.
I, WILLIAM HENRY PUNCHARD of 151 Cannon Street, in the City of London
Engineer and Contractor do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements in depositing apparatus to be used
in the construction of harbour, dock and quay walls, breakwaters, piers and like works.
The apparatus is specially adapted for depositing concrete in large masses either
before it has set or in blocks between piles forming a gantry or road along which it is
arranged to travel; the apparatus can however be employed to deposit other material.
It consists of a platform carried on side girders which are mounted on wheels upon
which it runs or travels.
These side girders also carry between them a skip or trough hung on trunnions or
otherwise fixed or suspended.
The platform carries the motive power for working the apparatus including
travelling gear, and gear for tipping the skip or otherwise delivering its contents.
The working of the machine is as follows. The whole apparatus is run back to a
suitable place on the gantry or road, and loaded from tip wagons, a crane or otherwise.
If the concrete is to be deposited before it has set the skip is lined with canvas or
jute which is sewn up to retain it in one mass.
When loaded the apparatus is run out on the gantry or road to the position required,
the contents deposited, and then run back into position for reloading.
Instead of making the skip to tip it may be provided with a falling bottom
or side, and it may also be arranged to lower the skip to any desired depth before
depositing the contents: This is especially necessary when working in very deep water
or where the rise and fall of tide is great.
By means of this apparatus several hundred ions of concrete may be delivered in
a single mass.
It is to be understood that all the movements the apparatus has to perform such as
self propulsion, hoisting or lowering the skip, opening or revolving the same for
discharging the contents is done by the machinery carried by the apparatus which
may be worked by means of a steam or other engine.

Improvements in Depositing Apparatus to be Used in the Con-
struction of Harbour, Dock, and Quay Walls, Breakwaters,
Piers, and like Works.
I, WILLIAM HENRY PUNCHARD of 151 Cannon Street in the City of London,
Engineer and Contractor (a communication to me from abroad by William Charles
Punchard of La Guaira in the Republic of Venezuela, South America, Civil 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
This invention has for its object improvements in depositing apparatus to be used
in the construction of harbour, dock and quay walls, breakwaters, piers and like works.
The apparatus is specially adapted for depositing concrete in large masses between
piles forming a gantry or road along which it is arranged to travel; the apparatus
can however be employed to deposit other material.
It consists of a platform carried on side girders which are mounted on wheels upon
which it runs or travels.
These side girders also carry between them a skip or trough hung on trunnions or
otherwise fixed or suspended.
The platform carries the motive power for working the apparatus including
travelling gear, and gear for tipping the skip or otherwise delivering its contents.
The working of the machine is as follows:-
The whole apparatus is run back to a suitable place on the gantry or road, and
loaded from tip wagons, a crane or otherwise.
If the concrete is to be deposited before it has set the skip is lined with canvas or
jute which is sewn up to retain it in one mass.
When loaded the apparatus is run out on the gantry or road to the position required,
the contents deposited, and then run back into position for reloading.
Instead of making the skip to tip it may be provided with a bottom or side made
to open and it may also be arranged to lower the skip to any desired depth before
depositing the contents; This is especially necessary when working in very deep
water or where the rise and fall of tide is great.
By means of this apparatus materials may be deposited in very large masses, both
quickly, economically and accurately.
It is to be understood that all the movements the apparatus has to perform such as
self propulsion, hoisting or lowering the skip, opening or revolving the same for
discharging the contents is done by the machinery carried by the apparatus which
may be worked by means of a steam or other engine.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation, fig. 2 a general plan, and fig. 3 a side elevation:
which last best illustrates the machine and working of the same.
A. The gantry or road upon which the machine travels.
B. The side girders mounted on wheels.
C. The platform.carrying the motive power.
D. The skip (shewn suspended in trunnions).
Sometimes employ a skip with a side or bottom door. Also sometimes I so
arrange that the skip can be lowered before depositing its contents.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :—
1. The apparatus consisting of side girders mounted on wheels and carrying between
them a wide skip and a platform on which is a motor all substantially as described.
2. The trough like skip D carried by trunnions between side girders B B and
capable of being tipped to deliver its contents substantially as described.
3. A skip with bottom or side arranged to open and carried between side girders B B
supported on wheels along a gantry or road A substantially as described.
4. Apparatus substantially as described and represented by the annexed drawings.
