hereby declare the nature of this invention to be as follows:-
The object of my invention is to construct a rotary machine which shall mould
press and emboss bricks, tiles or other like articles made from clay or other plastic
materials and also punch and camber such articles when required. For this purpose
the clay or plastic material is fed from a pug mill, roller machine, or by other
equivalent means into my rotary moulding and pressing machine, which consists of
two adjustable wheels or rollers, one, or both of which may be flanged and mounted
in a strong frame; one or both wheels or rollers being so constructed on its rim'or
surface as to form or receive a series of dies with a moveable division between each
die. When the wheels or rollers are rotated and the clay or other plastic material
passed between them, each die in succession receives a portion of the material,
moulds, presses and embosses the same and delivers the article so formed on the
opposite side of the machine. To facilitate the delivery of the moulded and pressed
articles, I construct the divisions between each die of a moveable piece of metal ;
which by means of suitable mechanism is slid or removed into a convenient position
for the easy delivery of each article. In the case of articles requiring to be curved
or cambered, I attach to the machine a separate roller or rollers in such a position.

Improvements in Machinery for Brick and Tile Making.
I EDWARD PHILP BASTIN, 49 Finsbury Pavement, London E.C., 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 object of my invention is to construct a rotary machine which shall mould,
press and emboss bricks, tiles or other like articles made from clay or other plastic
materials and also punch' and camber such articles when required. For this purpose
the clay or plastic material is fed from a pug mill, roller machine, or by other
equivalent means into my rotary moulding and pressing machine, which consists of
two adjustable wheels or rollers, one, or both of which may be flanged and mounted
in a strong frame; one or both wheels or rollers being so constructed on its rim or
surface as to form or receive a series of dies with a moveable division between each
die. When the wheels or rollers are rotated and the clay or other plastic material
passed between them, each die in succession receives a portion of the material,
moulds, presses and embosses the same and delivers the article so formed on the
opposite side of the machine. To facilitate the delivery of the moulded and pressed
articles, I construct the divisions between each die of a moveable piece of metal ;

page_text: which by means of suitable mechanism is slid or removed into a convenient position
for the easy delivery of each article. In the case of articles requiring to be curved
or cambered, I attach to the machine a separate roller or rollers in such a position
as to give the required shape, the roller or rollers being actuated by the friction of
the article passing it or by other suitable mechanism, means or device. In the
case of articles requiring to be punched, I attach a moveable punch or punches to
each die, the same being actuated by suitable mechanism so as to remove them out
of the way when the article is being delivered. In some cases depending upon the
nature of the material employed and the character of the mould, the tiles or other
articles are cut by means of a knife or wire after they are pressed or embossed.
To enable my invention to be clearly understood I will now describe the same
by means of the accompanying drawing, in which :—
Fig. 1, is a front.view.
Fig. 2. is a side view.
Fig. 3. is an enlarged view of pressing, dividing and punching mechanism.
The clay or other plastic material to be treated is fed forward from the pug
mill, roller machine or by other means in a layer of suitable thickness on to the
table 1, (see Figs. 1, 2, in the direction of the arrow,) the moulding, embossing,
punching, dividing and delivering being effected by the two wheels 2, 3, which
revolve upon shafts 4 and 5, mounted in bearings 6 and 7, which are adjusted to
any required height by packing and are bolted to the standards A. of the machine.
The wheels 2, 3, are made to revolve at the same rate of speed by means of the spur
wheels 8, 9, which are also keyed to the shafts 4, and actuated by the pinion 10,
and fast and loose pulleys 13, 14, mounted upon the counter shaft 11, supported in
bearings 12, 121 and driven by a belt from line shafting, or in any other convenient
manner. The lower wheel 3, has a shroud 15, on both sides, and the upper wheel
which preferably of the disc type is so formed upon its face as to mould the
brick, tile or other article direct, or for fancy moulding it may be fitted by bolting
or like means with a series of dies, between each of which is a moveable division
or dividing plate 19, which when operated as hereinafter described passes through
a series of slits 16, formed in the face of the. wheel 2. In the drawing eight such
slits are shewn, but the rim may be so divided as to mould or emboss any required
length, divide and deliver the same. Within the rim of wheel 2, are formed a
corresponding number of bosses 17, (see Fig. 3) to the slits in the rim, these are
bored and each fitted with a plunger 18, the lower part of which is slotted and carries
a dividing plate 19, which is secured to the plunger by rivets. The upper end of
the plunger 18, is bevelled off as at 21 and immediately beneath a screw is formed
on which is threaded a washer 22, between which and the top of the boss 17, is a
spiral spring 23. Mounted upon the hub of wheel 2, is a metal ring 25 into which
an adjustable pin 24, having a bevelled end 27 is screwed, the ring is prevented
from.coming off the hub of the wheel 2 by a collar and set screw 26 and is prevented
from turning with the wheel by the fork 28, bolted to the framing. Attached to
the dividing plate 19, by angle plates 29 are two punches 30, 31, which are adjusted
and secured by the double nuts 32, which engage with the threads upon the upper
part of the punches. A scraper 33, is mounted upon one of the tie rods 34.
The operation of my invention is as follows:-
The machine being set in motion, each of the plungers 18, is in turn brought
under pin 24, the onward motion of the wheels causing the inclines 21, 27, formed
on plunger 18 and pin 24 to rub against each other, with the result that the
moveable division or dividing plate 19, and the punches 30, 31 are forced downward,
perforating the brick or tile as the case may be parting and delivering the same
as shewn on the left of Fig. 2. In the case of fancy bricks or tiles the wheel 2,
is raised by packing the bearings to a sufficient height, and dies mounted by
bolting or like means upon the rim ; as the plastic material is forced forward the
dies impress the pattern upon the clay or like material which is then divided off as
just described.
I find in practice that the apparatus when constructed as described by itself

page_text: imparts the requisite camber to the tiles, or other like articles operated upon. If
however an unusually sharp camber is required, it may be obtained by the employ-.
ment of a separate set of rollers.
A recess 35 is formed in the rim of wheel 2, or in a metallic strip 36 inserted
therein, which forms the nibs 35' shewn on the tile to the left of table 1.
I am aware that apparatus for dividing streams of clay has been described in
which rigid radial knives or wires, or fixed or pivoted inclined blades operated by
an eccentric motion are employed for dividing the stream of clay into the required.
lengths, or in other cases independent knives are employed for this purpose, I lay
no claim to devices of this kind.
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 apparatus for forming bricks, tiles, and the like, the particular combination.
and arrangement of parts herein described operating together for effecting the
purposes set forth.
2. In apparatus for forming or making bricks, tiles and like articles, the com-.
bination and use of the disc wheel 2, having transverse slits 16, upon its face and
internal bosses 17, each of which carries a bevelled plunger 18, and the moveable
division or dividing plate 19, having adjustable punches 30, 31, attached to it. The
stationary pin 24, having bevelled end 27, adjustably mounted on the hub of wheel 2,.
and prevented from turning by the fork 28, which pin engages with and depresses
the bevelled ends of the plungers 18, when the wheels 2, 3, are rotated by means
of the gearing described, and thereby punches and divides the tiles or like articles
moulded by the wheels 2 and 3 or the dies mounted upon the wheel 2 in the manner
set forth.
3. In apparatus for forming and making bricks, tiles and like articles, the com-
bination and use with the wheel 2, co-operating with and actuated by the gearing
described, of separate moulds bolted to the rim for moulding and embossing the
stream of clay, fed forward, punched and divided in the manner set forth.
