PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Depositing Concrete and other
Materials.
I WILLIAM CHARLES PUNCHARD of 151 Cannon Street in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
The apparatus consists of a carriage running upon rails and supporting a tipping
body. The under side of the latter is provided with rockers which rest on the top of
the carriage. Half of the length of each of these rockers is straight so that the body
when upright stands firmly on the carriage, the other half of the rockers is curved
and of such a form that the body tilts itself gradually over when released. The
front of the body is arranged as a door hanging on pivots on the top of the sides.
Catches are provided to retain the door and also to hold the receptacle down on to
the carriage. The wheels of the carriage are driven by worm and worm gear, so
that the last part of the movement towards the edge of the embankment, pier or
the like which is being constructed may be effected gradually.
The working of the apparatus is as follows.
When the carriage has been brought to the edge of the embankment or pier
the catches are released, the material to be deposited then pushes the door slightly
open and overhanging causes the body to tilt and roll slowly forward on the
rockers and deposit its contents in position in front of the apparatus, the motion
being so gentle that concrete can be delivered without breaking the bags con-
taining it.

Improvements in Apparatus for Depositing Concrete and other
Materials.
L, WILLIAM CHARLES PUNCHARD, of 151 Cannon Street, in the City of London,
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
The apparatus consists of a carriage running upon rails and supporting a tipping
body. The under side of the latter is provided with rockers which rest on the top
of the carriage. Half of the length of each of these rockers is straight so that
the body when upright stands fimly on the carriage, the other half of the rockers
is curved and of such a form that the body tilts itself gradually over when released.
The front of the body is arranged as a door hanging on pivots on the top of the
sides. Catches are provided to retain the door and also to hold the receptacle down
on to the carriage. The wheels of the carriage are driven by worm and worm gear,
so that the last part of the movement towards the edge of the embankment, pier
or the like which is being constructed may be effected gradually.
The working of the apparatus is as follows.
When the carriage has been brought to the edge of the embankment or pier the
catches are released, the material to be deposited then pushes the door slightly open
and overhanging causes the body to tilt and roll slowly forward on the rockers and
deposit its contents in position in front of the apparatus, the motion being so gentle
that concrete can be delivered without breaking the bags containing it.
In order that my said invention may be fully understood and readily carried into
effect 1 will proceed to describe the drawings hereunto annexed.

Figure 1 is an elevation of apparatus constructed in accordance with my
invention; one half of the figure is front elevation and the other half is rear
elevation.

Figure 2 is a plan; as to one half of the figure the tipping body is removed in
order that the carriage below may be clearly seen.
Figure 3 is an end elevation and shows the apparatus advancing towards the edge
over which it is to tip its contents.
Figure 4 is also an end elevation and it shows the apparatus whilst delivering.
aaa are rails on which the apparatus runs.
is the under carriage; it is
supported by wheels b. 2 is an axis which couples together some of these
wheels. 33 are worm wheels on this axis. cc are other axes carrying worms
in gear with the wheels 6. c c are capstan heads and bars by the aid of which
the axes care turned and the carriage moved to the position required. dd is
the body and dare rockers upon the body which rest upon plane surfaces
upon the under carriage. d is the door and d³ ³ are the pivots by which the door
is hung. The door when closed is retained by catch levers on an axis d and this
axis is geared by means of bevelled pinions with other axes d which in order to
release the door are turned by hand levers. ee are locking levers to prevent the
body tipping until required and ffare guards to prevent the body tipping too far.
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. Apparatus for depositing concrete and other materials in which an under
carriage, a body on rockers and a pivotted door are combined substantially as
described.
2. Apparatus substantially as represented by the annexed drawings.
