Overhanging Depositing Apparatus to be Used in the Construction
of Piers, Breakwaters, Dock and Quay Walls, 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 by means of an over-
hanging apparatus to be used in the construction of piers, breakwaters, dock and quay
walls, and like works.
This apparatus is designed for constructing quay walls, piers, breakwaters or moles:
and is intended to deposit in place concrete (either before it has set or in blocks) or
other material in large quantities.
The apparatus travels on the finished work which it has constructed or on a road
prepared for it.
The apparatus consists principally of two girders braced together at both upper and
lower booms.
The portion resting on the road is carried on wheels by means of which the whole
apparatus can be made to travel forwards or backwards.
The girders project about half their length beyond the supports.
The lower cross bracing carries roads, rails and cross overs for the wagons or irollies
which supply the material. The upper cross bracing carries the engine boiler and
machinery and a counter balance tank.
A traveller is carried on rails on the upper boom of each girder and from it is
suspended a skip, either made to revolve in trunnions, or with bottom or side made to
open and arranged to lift and lower should it be required.

page_text: The working of the apparatus may be briefly described as follows:-
It is moved forward to the position it will have to occupy for the day or time
necessary for the construction of the portion within its overhang and the ballast tank
is filled.
The traveller brings the skip back to be loaded and it is then moved out to the
position required where the contents are deposited.
The skip is preferably made the full width of the work-breakwater, quay wall &c.
The apparatus can also be constructed to revolve on the carriage if required.
Blocks may be suspended from the traveller instead of the skip.
The machinery is arranged to perform all the movements required-moving the
whole machine on its travelling wheels, turning it round, moving travelling frame
forwards and backwards on rails along the upper boom; emptying the skip, either by
revolving it, or opening the bottom or side and reclosing same; and lifting or lowering
the same if required.

vernanging Depositing Apparatus to t Used In the
of Piers, Breakwaters, Dock and Quay Walls, 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 by means of an over-
hanging apparatus to be used in the construction of piers, breakwaters, dock and quay
walls, and like works.
This apparatus is designed for constructing quay walls, piers, breakwaters or moles:
and is intended to deposit in place concrete (either before it has set or in blocks) or
other material in large quantities.
The apparatus travels on the work which it has constructed or on a road prepared
for it.
The apparatus consists principally of two girders braced together at both upper and
lower booms.
The portion resting on the road is carried on wheels by means of which the whole
apparatus can be made to travel forwards or backwards.
The girders project about half their length beyond the supports.
The lower cross-bracing' carries roads, rails and cross overs for the wagons or trollies
which supply the material. The upper cross bracing carries the engine, boiler and
machinery and a counter balance or ballast tank.
A traveller is carried on rails on the upper boom of each girder and from it is
suspended a skip, either made to revolve on trunnions, or with bottom or side made to
open and arranged to lift and lower should it be required.
The working of the apparatus may be briefly described as follows
:-
It is moved forward to the position it will have to occupy for the day or time
necessary for the construction of the portion within its overhang, and the ballast tank
is filled.
The traveller brings the skip back to be loaded and it is then moved out to the
position required where the contents are deposited.
The skip is preferably made the full width of the work-breakwater, quay wall &c.
The apparatus can also be constructed to revolve on the carriage if required.
Instead of the skip blocks of concrete or other materials may be suspended from the
traveller and set into position.
The machinery is arranged to perform all the movements required, moving the
whole machine on its travelling wheels, turning it round, moving travelling frame
forwards and backwards on rails along the upper boom; emptying the skip, either by
revolving it, or opening the bottom or side and reclosing same, and lifting or lowering
the same if required.

page_text: In order that my said invention may be fully understood and readily carried int
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation, and Fig. 2 a front elevation of a machine travelling o
work already constructed-as for jetties, breakwaters, &c.
Figure 3 is a side elevation of a machine travelling parallel to its work as for se
walls, quays, dock walls, &c.
Figure 4 is a side elevation of the machine with a short overhang.
A. The side main girders.
B. Top bracing-which also carries the counter balance or ballast tank C.
1. Bottom bracing carrying roads or rails.
E. Carriages on which the machine travels.
F. Traveller from which the skip is suspended by the arms G.
1. Skip revolving on trunnions.
T. Skip with side made to open.
J. Skip with bottom made to open.
K. Finished work.
1. Bank or shore.
In all the figures like letters denote the same parts.
Having now particularly described and ascertained the nature of the said inventio
and in what manner the same is to be performed I declare that what I claim is :-
-
1. Overhanging depositing apparatus consisting of girders firmly braced togethe
and supported on carriages which they overhang at one end and a traveller wit
suspending arms carrying a skip substantially as described.
2. In combination with overhanging depositing apparatus such as above set fort
the roadway provided on the lower cross bracing for wagons or trollies to supply th
material to the skip, substantially as described.
3. In combination with overhanging depositing apparatus such as above set fort
the skip of greater width than the girder frame, carried by suspending arms outsi
the said frame and either revolving on trunnions or opening substantially as describe
4. Overhanging depositing apparatus substantially as described and represented
the annexed drawings.
