CHARLES HENRY MURRAY, of Loman Street, in the Borough of Southwark,
Engineer. "AN IMPROVED MODE OF TRANSFERRING GREEN BRICKS AND TILES
FROM THE CUTTING TABLE TO THE HACKS OR DRYING SHEDS."
The object of this Invention is to effect an economy in the manufacture of bricks
and tiles by the mechanism described in the Specification of my Patent bearing date
the 8th June 1866, No. 1581. In this Specification I havo described the use of
vertical cutting wires set in a fixed frame, and against which the blocks delivered
from the moulding die are forced to reduce the same to the form of bricks or tiles
as desired. In working this machinery the assistance of two labourers is required,
one of whom works the severing wire in front of the moulding die, while the other
forces the blocks thus severed in succession up to and past the dividing wires of the
fixed frame. Preparatory howevor to the forcing of the clay through this dividing
frame, a board is placed (in advance of the frame) horizontally upon the dividing
table to receive the clay as it is divided up into the form of bricks. The workmen
then taking up the board at its opposite ends, place it upon an adjacent barrow
calculated to receive as a load some four of these boards of bricks. Another
attendant then wheels the barrow to the hacks or the drying sheds, and arranges
the green bricks in proper order for drying. I now propose to avail myself of the
motive force applied to the blocks of clay in the act of forcing them through the
dividing frame to load the barrow, and thereby to avoid the use of the loose boards,
and to render it unnecessary to lift the bricks in order to place them on the barrow.
The advantage which I obtain by avoiding the necessity for placing the bricks by
hand on the barrow is the saving of the labour of one workman. In order however
to attain this object, I bring the appliance for operating the severing wire within
reach of the man who propels the blocks of clay towards and through the dividing
frame, and I provide a barrow formed with a flat top or table of suitable dimensions,

the same.
The barrow top I arrange so that it shall slant slightly from the dividing frame
in order to facilitate the movement of the green bricks over its surface.
The
When a block of clay has been passed through the dividing frame, the workman
places behind it and in advance of the frame a board somewhat longer and higher
than the severed block. He then forces forward another block of clay which has
been cut off by the severing wire which works in front of the moulding die
passage of this second block through the dividing frame will press forward the
board which backs up the first lot of bricks delivered on to the barrow, and when
this second lot of clay is clear of the dividing wires the workman places a board in
its rear.
This operation he repeats, say four times, forcing forward the formed bricks
further and further on to the barrow, until the load for the barrow is completed.
An attendant then wheels off the loaded barrow, and another barrow of like
construction is brought into position to receive in its turn a batch of bricks.
The bricks are removed from the barrow by hand and stacked as usual for
drying, or placed upon the floor of the drying shed. They may be conveniently
lifted off the barrow in couples by the aid of "pads" applied to their opposite ends.
