Improvements in the Construction of Cutting-off Tables for Bricks
and other Blocks.
I, WILLIAM WOOD, of No. 3, Bridlington Street, Armley, Leeds, in the County
of Yorkshire, Engineer, do hereby declare the nature of this invention to be as
follows:
-
The object of my invention is to construct an improved cutting off table for
cutting bricks or other blocks from a column of clay or other material as delivered
from a pug mill or brick making machine.
In order to carry out the improvement in my invention I fix an adjustable
table on which the column of clay is delivered on suitable framework of cast iron
in one or more pieces. I fix two toothed racks on suitable guides provided on the
framework and on these racks I fix a lubricating cutting board or plate to force
the column of clay through the wires on to a board fixed on the other side of
cutting wires. The said toothed racks are operated by an handle attached to a
toothed quadrant supported on a shaft running through the framework.
I provide on the framework adjustable stops to lengthen or shorten the travel
of the aforesaid lubricating cutting board or plate to suit the different lengths
of bricks or blocks to be cut.
I also provide on the framework suitable supports to receive adjusting screws
to raise or lower the aforesaid adjustable table to suit the different depths of
bricks or blocks to be cut.
I also provide on the framework suitable supports to receive the bottom wire
hook frames. I fix to the framework adjustable brackets to be raised or lowered
to suit the different depths of bricks or blocks to be cut. These brackets are
provided with a sliding arrangement to allow the brackets being lengthened or
shortened to suit different lengths of bricks to be cut.
The said brackets are
used for supporting the fixed boards herein before mentioned on the outer side of
the wire frames and also for supporting a removable board for receiving the
finished cut bricks ready for being placed on the barrow. I fix to the framework
brackets arranged to receive adjusting screws to raise or lower the board which
receives the column of clay as delivered from the pug mill or brick machine to
suit different depths of bricks or blocks to be cut, also to raise or lower the 'oi!
roller next the die to suit different bricks or blocks to be cut. The oil roller
dish is provided with adjusting screws for raising or lowering the said dish
and roller. I mount on the top of framework suitable supports provided to
receive the top wire frame and top adjustable wire gauge also a bottom fixed wire
or adjustable gauge. Also adjustable smoothing rollers under which the bricks
pass as they are pushed through the wire frame. The whole working parts are
adjustable to suit different lengths and depths of bricks or blocks to be cut with-
out interfering with the table feet. I make this table for a double or single
cutter as required.

page_text: I propose constructing the table suitable for a single or double delivery accord-
ing the requirements of a large or small production.

COMPLETE DIEUITIVATION.
Improvements in the Construction of Cutting off Tables for Bricks
and other Blocks.
I, WILLIAM WOOD, late of No. 3, Bridlington Street, Armley, Leeds, in the
-County of Yorkshire, Engineer, and now residing at No. 35, Hero Street, off
Hawthorne Road, Bootle, Liverpool, 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 object of my invention is to construct an improved cutting off table for
cutting bricks, or other blocks from a column of clay or other material, as
delivered from a pug mill, or brick making machine. In order that the improve-
ments in my invention may be better understood, reference is made to the accom-
panying drawings.

applied to it.
Fig. 2 is an end elevation of the same.
Fig. 3 is a plan.
Fig. 1 and Fig. 2 A. represents the main framework of the table to which I fix
adjustable screws B, shown in Fig. 2. To these adjustable screws I fix a
table C, to be raised or lowered to suit the different depth of bricks or blocks to
be cut, without interfering with the table feet. I fix on top of the main frame-
work A, the wire frames D, shown in Fig. (1-2) constructed to receive and
secure the top adjustable wire gauges E, shown in Fig. (1-2). Also to receive
and secure adjustable hollow guides F, shown in Fig. (1-2-3) for receiving and
keeping in position the smoothing rollers G, shown in Fig. (1--2-3). Also for
receiving the permanent bottom wire gauges H, shown in Fig. 1.
Also to receive
On
and secure the slotted bars I, shown in Fig. (1-2), supporting and carrying the
top of the wires J, shown in Fig. (1-2-3). I use in the adjustable hollow
guides F, smoothing rollers G, to roll down the rough cuts or arris, caused by the
bricks, or blocks passing through the wires J, shown in Fig. (1-2-3).
planed guide blocks K, shown in Fig. (1-2-3), cast on the main framework A.
Toothed racks L shown in Fig. (1- -3), truly planed inside and outside, slide
on the engine principle. The top of these racks are prepared to receive and
secure a cutting or pushing board M, shown in Fig. (1-2-3). This board is
hollowed out along the top and perforated from the outside, into the hollow recess,
for the purpose of receiving oil which flows through the perforations, and
lubricates the faces of the board, to prevent the soft ends of the bricks or blocks,
sticking to the board when being pushed through the wires J. The racks L and
cutting or pushing board M are operated by the handle N shown in Fig. (1-2-3).
Being attached to the toothed quadrants 0, shown in Fig. (1-2) fixed on a
shaft P shown in Fig. (1-2-3), running through the main framework A. I fix

page_text: to the main framework A adjustable brackets Z, to regulate the travel of the
hande N, attached to the toothed quadrants 0, to cut long or short bricks or
blocks. I fix to the main framework A adjustable brackets Q as shown in Fig. 1
and 2, to be raised or lowered to suit the different depths of bricks, or blocks, to
be cut. The brackets Q, are grooved on top, and fitted with sliding pieces R,
shown in Fig. (1-2-3), that can be drawn outward or inward to suit the
different lengths of bricks, or blocks, to be cut. To the main framework A, I fix
brackets S, shown in Fig. 1 and 3 to which I fix adjustable screws T, shown in
Fig. 1. To these adjustable screws, I fix a table U, shown in Fig. 1 and 3, to be
raised, or lowered, to suit the different depths of bricks, or blocks, to be cut. I
also fix to the brackets S, adjustable screws V, shown in Fig. 1, on which I use
loose guide rollers W, shown in Fig. (1-2-3). to guide the column of clay
coming from the machine die in a straight line along the tables U, and C, to
prevent the column of clay coming into contact with the end of the cutting, or
pushing board M, or the bricks, or blocks, part cut in the wires J, shewn in
Fig. (1-2-3). The guide rollers W, are hollowed out on, and round the top,
and perforated from the outside into the hollow recess, for the purpose of
receiving oil, which flows through the perforations and lubricates the outside
of the rollers. To prevent the column of clay coming from the machine die
sticking to them. I also fix to the brackets S, adjustable screws X, shown in
Fig. 1.
To these screws I fix an oil dish Y, shown in Fig. 1 and 3 in which
runs a loose roller, which gathers up the oil, and lubricates the column of clay,
coming from the machine die, on the underside; so that the table tops U, and C, are
lubricated with the oil on the underside, the column passing over them.
On top of the adjustable brackets Q, and sliding pieces R, I fix two fast, and
two loose boards. The fast boards are to receive the bricks part cut. The loose
boards are to receive the bricks wholly cut, and ready to be put on the barrows,
to be taken away.
The top adjustable wire gauges E, shown in Fig. 1, can be raised or lowered in
the slots, in wire frames D, to suit the different depths of bricks or blocks to be
cut.
I use a wire in the framework (0) (1-2-3) to cut off the desired length of
clay to be cut into bricks or blocks.
DESCRIPTION OF TABLES.
This invention has for its object a more effectual way of treating the clay, as
it is delivered from the machine die, or pug mill, or equivalent, of any usual
method is to use a series of small rollers, to convey the column of clay delivered
from the die, or pug mill, or equivalent, on to the cutting table; which is then
forced through the wires, on to a board ready for the barrow. This method has
disadvantages, that we will not stop to inquire into. The principle ones are,
that the series of small rollers, roll out or flatten the bottom side of the column
of clay, as it passes over them on to the cutting table; thus making the bricks
when cut longer, on one side than the other. So making it practically impos-
sible to make good work in a building, also the bricks being forced through the
wires, and finished with one cut, get more or less the ends torn out in leaving
the wires.
In my invention I use one large roller, only for lubricating the underside, the
clay passing over it. The clay thus lubricated travels along a plate, with a very
smooth surface, on to the cutting table. The clay is then forced partially through
the wires, and remains there until the next column of clay comes along for cut-
ting. This second column of clay is then forced against the clay or bricks par-
tially cut, finishing the cut of them, and delivering them
on to the
board, ready for the barrow leaving the others partially cut in the
wires. This second cut secures a perfect brick at both ends, and by
useing the one large lubricating roller, and plate, I practically avoid the
rolling out or flattening of the bottom side of the column passing over them on
to the cutting table,
