PROVISIONAL SPECIFICATION.
Improvements in Brick and Tile Making Machinery.
I, DANIEL RANKINE ADAM, of Inkerman Brickworks, Paisley, Renfrewshire,
Brick Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention relates to machinery for making bricks and tiles and it has
for its object to provide means whereby existing brick making machinery can be
utilized for making corner, round nosed, splay and any other desired shape and
style of brick or tile without necessitating the alteration of the moulds of the
filling table.
The desired shape of brick is made from a common square block of roughly
pressed blaes," clay, or other suitable brick making material.
In carrying out the invention, to the usual plunger rods or bolts, actuated
by the cross head and having a vertical up and down motion, is fitted a fork
shaped device having, at one end, a suitable knife or other cutting or shearing
instrument which is fashioned to the desired shape and is secured in position by
means of a bolt and nut or other suitable arrangement. A slot may be made
in the device for the purpose of adjustment. The knife or other cutting instru-
ment is so fixed as to be held rigidly in place.
.
As the square
"clod comes from the filling table it passes along a slide or
guideway which is provided with an opening just below the knife or cutting
instrument aforesaid so that when the knife descends, guillotinewise, is cuts
off a portion of the "clod" which portion falls down through the opening out
of the way and does not block up the slide or guideway. The descent of the
knife is so arranged as to take the second "clod" that comes from the table.
The "clod," cut in the manner hereinbefore described, passes along the guide-
way and drops into a finishing press box. This box is provided with a liner either
made all in one piece or in separate pieces which are arranged to lock or fit
into one another. The liner, made in one piece or in sections as aforesaid.

I, DANIEL RANKINE ADAM, of Inkerman Brickworks, Paisley, Renfrewshire,
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:--
This invention relates to machinery for making bricks and tiles and it has
for its object to provide means whereby existing brick making machinery can be
utilized for making corner, round nosed, splay, and other odd shapes and styles
of brick or tile without necessitating the alteration of the moulds of the filling
table.
The desired shape of brick is made from a common block of roughly pressed
"blaes," clay, or other suitable brick making material.
In order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings which shows, by way of example,
part of the well known "Bradley and Craven" brick making machine with my
improvements applied thereto.
Referring to the drawings:.
Fig. 1 is a plan view showing part of the filling table and the press box of
the machine as well as the parts connected therewith.
Fig. 2 is a vertical section taken on the lines A-A and B-B of Fig. 1.
Fig. 3 is a plan view of the press box.
Figs. 4 and 4 show different forms of cutting knives.
Fig. 5 shows a construction of liner.
a represents the filling table of the machine, b the press box, e the clod of
clay, the guide way for the clod, e the interior of the press box, f the
ram for pushing forward the clod to the mould, g, g, the guide rods for the
ram, h the lever for actuating the ram, i the vertically reciprocating cross head
of the machine and the guides for the cross head.
In carrying out my invention I secure, by means of the studs k. to the vertically
reciprocating cross head a fork shaped device / having, at one end, a suitable
knife m which is fashioned to the desired shape and is secured in position by
means of the screwed extension forming a bolt and the nuts o, o¹. The extension
is passed through a hole in the device and the nuts o are thereafter fitted in
place and tightened up. I. desired instead of the hole a slot may be provided
in the device so as to permit of an adjustment of the knife. The knife, when
the nuts are tightened up, is held rigidly in place.
As the " clod"
c comes from the filling table a it passes along the guideway d
which is provided with an opening just below the knife m so that, when the
knife descends, guillotine wise, along with the crosshead i, a portion of the
"clod" is cut off and falls down through the opening into the receiver and
therefore does not block up the guideway. The descent of the knife is so arranged
as to take each "clod" as it comes from the table.
The "clod," cut in the manner herein before described, passes along the guide-
way and drops into the finishing press box b. The interior of this box is pro-
vided with a liner made in three pieces r, r1, 12, which are arranged to lock or
fit into one another in the manner shown clearly at Fig. 3. The pieces enclose
a space which is of the exact size and shape of the finished brick. The
pieces r, r,, can be readily fitted together and inserted in place or taken out
and changed. If desired flat lining strips r, r¹, r², r³, may, as shown at Fig. 5,
be used for the sides of the box and a separate piece inserted and fitted to the

page_text: strips, by pins (indicated by the dotted lines) so as to give the required shape to
the brick. The pieces of the liner can be made of cast iron, cast steel, or gun-
metal, and can be retained in place within the box by means of a ledge at
the bottom of the box upon which they can rest.
The side pieces of the guide way d overlap the pieces r, 2, 1, of the liner
so as to prevent them rising up out of place. As will be seen the guide way is
secured removably in place by studs When the guide way is removed the
pieces of the liner can be taken out of place.
The top and bottom press plates of the press box are made to correspond with
and fit into the design and shape of hollow formed by the liner in the box.
The piston t for pushing up the pressed brick is made of a shape corresponding
to the shape of the hollow e.
In Figs. and 2 the knife m shown is curved (see Fig. 1) so as to cut off a
curved piece at the corner of the "clod" and thereby make a "bull nosed "
brick.
Figs. 4 and 4 show two different kinds of cutting knives. The curved knife ",
Fig. 4. is adapted for cutting a curved or
"circle brick. The knives and w
Fig. 4 are combined together at an angle to one another so as to cut off an
angular piece from the clod in order to make a double pointed" brick. The
two figures at the left hand of Fig. 4 are respectively an elevation and a plan
of the knives whilst the right hand figure is a back view of the knife r.
According to the kind of brick to be made the proper knife for the purpose is
fitted in the fork 7; and, when a different kind of brick is to be made then a
guide way with an opening p corresponding to the cutting knife is fitted to the
press box. A set of guides with the proper openings is provided.
The liner shown at Figs. 1 and 3 is for making bullnosed" bricks but if
other bricks are to be made then lining pieces of the required shape would
be fitted in the press box. At the same time the proper knife and guide way
would be fitted to the machine.
It will be seen that the knives have projections or ledges these are for forcing
down into the receptacle q through the hole the pieces of clay cut off the
"clods."
I am aware that liners made in pieces have been used before and I make no
claim therefor.
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 consider novel and desire to claim is:-
-
1. The combination with a brick making machine of a device connected with
the machine so as to reciprocate vertically, a knife fitted to the device for cutting
a piece off the "clod," and a guide way having an opening therein corresponding
in shape to the piece cut off the "clod," substantially as hereinbefore described.
2. The combination with a brick making machine of a device connected with
the machine so as to reciprocate vertically, a knife fitted to the device for cutting
a piece off the "clod," a guide way having an opening in it corresponding in
shape to the piece cut off the "clod," and a press box having a liner made in
pieces which fit together and when fitted correspond to the shape of the brick
to be manufactured, substantially as hereinbefore described with reference to the
drawings annexed.
