PROVISIONAL SPECIFICATION.
Improvements in Machines for Cutting Clay or like Material into
Bricks or Blocks.
I, THOMAS BUCK, of Stanley Road, Cambridge, in the County of Cambridge, do
hereby declare the nature of this invention to be as follows:-
My invention relates to what are known as brick cutting tables in which lengths of
clay, cut off by a cutting wire and then forced forward by a thrust plate operated by
a lever, are cut into a certain number of bricks or blocks by a series of fixed
cutting wires acting thereon.
In such machines as hitherto constructed a waste piece is left from each end of the
lengths of clay after the bricks or blocks have been cut therefrom, and the object of
my invention is to so construct the machine that it will cut the clay fed from the die
of the exact length to form the 'given number of bricks or blocks and thereby avoid
waste.
In carrying out my invention I arrange the wire for cutting off the lengths of clay
in a frame attached to another frame adapted to slide in guides on the sides of the
cutting table, a stop lever being employed for the clay to abut against while being cut.
A stop fitted with a roller or rollers allows of the length of clay being placed in
proper position on the table so that the distance between, the end of the length of clay
and the first of the series of fixed cutting wires is exactly the thickness of a brick or
block, and there is therefore no surplus clay left after cutting up the length.

Improvements in Machines for Cutting Clay or like Material into
Bricks or Blocks.
I, THOMAS BUCK, of Stanley Road, Cambridge, in the County of Cambridge, Brick
Manufacturer, 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:-
My invention relates to what are known as brick cutting machines in which lengths
of clay, cut off by a cutting wire and then forced forward by a thrust plate operated
by a lover are cut into a certain number of bricks or blocks by a series of fixed,
cutting wires acting thereon.
In such machines, as hitherto constructed, a waste piece is left from each end of the
length of clay after the bricks or blocks have been cut therefrom, and the object of
my invention is to so construct the machine that it will cut the clay, fed from the die,
of the exact length to form the given number of bricks or blocks and thereby avoid
waste.
In carrying out my invention I arrange the wire for cutting off the lengths of

page_text: clay in a frame attached to another frame alapted to slide in guides on the sirles
of the cutting table, a stop lever being employed for the clay to abut against
while being cut. A stop fitted with a roller or rollors allows of the length of
clay being placed in proper position on the table so that the distance between the
end of the length of clay and the first of the series of fixed cutting wires is
exactly the thickness of a brick or block, and there is therefore no surplus clay left
after cutting up the length.
To enable my invention to be fully understood I will describe it by reference to the
accompanying drawing, in which :-
Figure 1 is 'a plan of a machine, for cutting clay or the like, having my improve-
ments applied thereto.
Figure 2 is an elevation, and
Figure 3 a sectional end view of the same.
Figures 4 and 5 are views of details, the latter being a section on the line 5-5
Figure 1.
a are the standards or supports of the machine. b is the bed of the machine, and
care the wires for cutting the length of clay or the like into bricks or blocks: d is the
thrust plate by means of which the length of clay or the like is forced against
the wires and cut into a number of bricks or blocks and ee are the rollers by
means of which the length of clay is fed on to the bed of the machine. All these
parts are of ordinary construction.
fis the wire for cutting off the lengths of clay, and g is the frame in which
it is mounted. his the frame in which the frame g slides the said frame being
provided with rollers A' at its upper end to reduce friction and facilitate the
movement of the frame which is effected by means of the handle g'. i, i are
the guides at the sides of the cutting table on which the said frame h slides as
. hereinafter described. To the frame is connected one end of a bar j which is
supported at its other end in a bracket & attached to the frame e carrying the
. cutting wires cc.
I is the stop lever the said lever being pivoted to a bracket m adjustably secured
to the end of the bar j by means of nuts nn; o is a plate on the end of the
stop lever designed to act as a stop for the length of clay from the die of the
machine, and o¹ (Figures 2 and 5) is a stop on the bracket to limit the downward
movement of the plate o. The lever is formed at the other end with a handle p so
that it can be rotated on its pivot into the position shewn in dotted lines in Figure 2
that is to say until it is arrested by the stop o'.
is the stop fitted with rollers g', the said stop being clamped to the thrust plate d
by means of the clamp q and designed to regulate the distance of the end of the
length of clay from the first cutting wire, and the rollers being employed to reduce
the friction when the thrust plate is returned to its normal position after having forced
the length of clay against the wires. The stop g is hinged at g so that it can bo
lifted from the bed of the machine as shewn in Figure 4.
The operation of the machine is as follows:--
The handle p is raised so as to lower the stop plate o into the position shown in
dotted lines in Figure 2, and the clay is fed on to the rollers e of the cutting table
and advances until its front end strikes against the said stop o. Further forward
movement of the clay then causes the said stop o and the bar j to move forward
whereby the frame h is also carried forward on the guides i. During this movement
the frame g is operated by means of the handle a' so as to cause the wire to cut off
the exact length of clay for producing the number of bricks or blocks required, the
said length being determined by the distance between the stop plate o and the wire f.
The stop o is now raised by lowering the handle p into the position shewn in full linos
in Figure, and the length of clay cut off is moved forward partly by rotating one
of the rollers e and partly by hand until it strikes against the stop g which has been
placed in such a position that the distance between the end of the length of clay and
the first cutting wire in the series is equal to the thickness of one brick. The thrust
plate d is now operated in the usual manner so as to cause the length of clay to be

page_text: cut into bricks by the wires cc and the frame his pushed back into its normal
position so that the machine is again ready to operate upon another length of
clay.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In machines for cutting clay or like material into bricks or blocks, wherein wires
are used for the cutting operations, mounting the wire for cutting off the proper
length of clay or the like in a frame adapted to slide in a second frame which slides
on suitable guides, substantially as, and for the purpose, herein before described.
2. In machines for cutting clay or like material into bricks or blocks, of the kind
described in the preceding claiming clause, an adjustable stop rigidly connected
with the second sliding frame, substantially as, and for the purpose, hereinbefore
described.
3. In machines for cutting clay or like material into bricks or blocks, wherein
wires are employed for the cutting operations, a stop fitted with a roller or rollers,
substantially as, and for the purpose, herein before described.
4. The improvements in machines for cutting clay or like material hereinbefore:
described and illustrated in the accompanying drawing.
