We, ALFRED WINROW, of No. 48 Lothian Road, Camberwell Road, and HERBERT
ROE TANDY, of No. 402 Kennington Road, both in the County of Surrey, Engineers,
do hereby declare the nature of this Invention to be as follows:-
This Invention relates to improvements in brick-making machinery, and is
principally adapted for making what are known as "sand faced and ornamental
bricks.
The apparatus consists of a rectangular feed box or hopper which is open at both
ends and has a lateral opening for the reception of the clay or other material from
the pug mill.
The hopper is fixed upon suitable supports in a vertical position and underneath it
is a bed upon which travel the dies or moulds. The bed is hinged at one end so that
it may be raised when it is desired to bring the face of the mould into contact with
the hopper, and lowered when it is necessary to remove the mould with the finished
brick. Level with the bottom of the hopper is a horizontal frame across which is
stretched a knife or wire for separating the material in the mould from the material in
the hopper. To the rectangular frame is also fixed a horizontal knife at a higher level
than the one previously mentioned, for the purpose of separating the material from
the plunger after the brick has been pressed, and thus prevent the plunger from
carrying the material with it in its upward movement.
The inachine is driven from a shaft on which are mounted three cams, one of which
operates through a lever to raise and lower the plunger, another imparis the horizontal
motion to the knives or wires, acting through the medium of a yoke, friction runners
and levers or other equivalent device, and the third raises and lowers the bed upon
which the mould rests being connected therewith through the medium of a hinged
lever and connecting rod.
The machine may be driven by either hand or power, and the details of construction
may be varied especially as regards the method of deriving the various motions from
the first driving shaft.

page_text: We ALFRED WINROW of No. 48 Lothian Road Camberwell Road, and HERBERT
ROE TANDY of No. 402 Kennington Road both in the County of Surrey, Engineers,
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 and accompanying Drawings:
This Invention relates to Improvements in Brick making Machinery and is
principally adapted for making what are known as "sand faced" and ornamental
Bricks.
The apparatus consists of a rectangular feed box or hopper which is open at both
ends and has a lateral opening for the reception of the clay or other material from
the pug mill.
The hopper is fixed upon suitable supports in a vertical position and underneath it
is a bed of radial or circular form upon which travel the dies or moulds revolving
around and upon a lower or partially fixed Bed, this said Bed is hinged at one end so
that it may be lifted or raised when it is desired to bring the face of the mould into
contact with the hopper, and lowered when it is necessary to remove the mould with
the finished brick. Level with the bottom of the hopper is a horizontal frame across
which is stretched or fitted a knife or wire for separating the material in the
mould from the material in the hopper. To the rectangular frame is also fixed a
horizontal knife at a higher level than the one previously mentioned, for the purpose
of separating the material from the plunger after the brick has been pressed by the
plunger working in the said rectangular frame, and thus prevent the plunger from
carrying the material with it in its upward movement and enables it to freely rise; so
that when the upper knife is caused to pass horizontally through the open space in the
Hopper it cuts or divides the Clay from the plunger at the same time it checks or
prevents the suction of air which might pass therein and be carried up into that
portion of the Clay ready for the next Brick to be made.
The Machine is driven from a Shaft on which are mounted three or more Cams,
either internal or external (or other suitable mechanical equivalents may be employed
if desired) one of which operates through a lever to raise and lower the plunger,
another imparts the horizontal motion to the knives or wires acting through the
medium of a yoke, friction runners and levers or other means or device, and the third
raises and lowers the under bed pivotted or hinged as described and worked or con-
nected therewith by the medium of a hinged lever and connecting rod and at the
same time the circular or rotating table or upper bed is caused to traverse and work
around upon the lower bed, and the moulds fit and rest upon the said upper circular
rotating table and are brought successively into exact position under and against the
lower portion of the hopper to be alternately and automatically fed or charged and led
therefrom to be afterwards dealt with and stored away.

page_text: As soon as the clay is pressed into the mould, the lower or wire knife divides the
clay from the mould and from the hopper and the upper knife passes through a slot in
the hopper and divides the clay from the plunger, both of which work simultaneously
and the table is lowered together with the mould a convenient distance to just permit of
the lower or wire knife to divide the clay between the hopper and mould, the table is
then again slightly lowered to a regulated extent and caused to rotate on the lower or
partially fixed Bed and bring as previously described another mould into position
under the plunger to be again operated upon. The action of rotating the table may
be caused by a lever motion from a Cam, the bottom of the lever being connected to
a connecting rod and lever the fulcrum of the latter lever which would be or may be
fixed to about or at the centre of the Bed of the machine, and upon the latter lever a
ratchet pawl or other equivalent would be fixed so as to work horizontally and radially
to and fro, which is caused to take or enter during its traverse alternately into slotted
portions or recesses guaged or formed in the under part of the rotating table at suitable
distances apart and causes the upper table or bed to rotate around and upon the lower
to a regulated extent and the pawl in its return or backward traverse acted upon by
the cam causes it to slide out of gear and into the next slotted recess provided and so
continues to repeatedly act. The number of slotted recesses provided for it to act upon
is in accordance with the number of moulds intended to be presented under the
plunger at one entire revolution or rotation of the table.
In place of the lever or cam arrangements and ratchet or pawl arrangement referred
to for causing the table to rotate, we may propose to employ other similar equivalents
or mechanical actions for the purpose.
The clay or other material is fed into the Hopper or receiver wherein the plunger
works, from a Pug Mill fixed or connected in close proximity to the said Hopper and
worked in the usual manner to facilitate the supply of the clay into the Hopper
which may be regulated in any suitable manner.
A vent hole or holes or pipe may be provided in the lower portion of the hopper,
having a weighted valve, spring or other attachment or means provided to permit of
its being effectually relieved in the case of being overfed or should an unnecessary
accumulation or supply more than is needed take place.
In the accompanying Drawings Sheets 1 and 2; Figure 1, exhibits a side elevation
shewing the general principle and arrangement of the working parts of a Machine
such as herein described. Figure 2 is an end view of the same and Figure 3 is a plan, in
which the following letters refer to like or or corresponding parts, viz. :-A, is the
rectangular feed box or hopper having an opening A', for the reception of the clay or
other material from an ordinary Pug Mill which is connected thereto and feeds the
same. B, B are the fore frames, supported by pillars or columns B¹, B¹, which
support the hopper A, and other connections, likewise at their upper parts form
bearings B2 B2, in which the lever connections C and D are pivotted and work therein,
and at their outer ends are fitted with small wheels or rollers and D¹, pivotted to
and working in a jaw provided therefor, the required and necessary motion to be
given to these respective levers is in the first instance by means of cither internal or
external cams, fitted upon and worked from the main shaft E, (but for the present
purpose are shewn as external).
The lever C is actuated and worked by means of the main cam F, which operates
and works the plunger G and rod connection G' working within the hopper A.
The lever D is likewise actuated by its cam H, for lowering or raising as the case
may be that part of the circular table under the plunger G, and at the instant
required, to free the mould and clay compressed therein froin under the plunger; J, is
the upper or rotating table working upon and around the lower circular Bed K. L, is
a spring secured at one end to the base of the machine and at the other to the lever C,
for the purpose of causing the small wheel or roller (at its end to bear firmly and
effectively onto the cam F. In the case of the cam H, provision is made on its
periphery to impart to the lever D, which it works, two separate and distinct upward
or downward movements which are caused by a connecting rod M, whose bottom end
is attached to the underneath portion of the lower circular hinged table K, as at N ;

page_text: at the upper part of this connecting rod M, is an internal adjustable screw M¹ for the
purpose of adjusting the rise or fall of the table under the plunger by means of the
adjustment screw M³.
A further cam 0, (or similar mechanical action employed) may be likewise worked
from the main shaft E, working against a wheel or roller P, contained and pivotted
in the jaws of a lever P, pivotted to the hind or side frame B³, to which a connecting
rod (or rods) Q, is jointed to the said lever P, so as to give horizontal motion to a
frame R, in which the knife or wires before referred to work with the said frame to
and fro' for separating or dividing the clay from the "mould" and hopper likewise the
plunger a spring S, is provided to ensure the small wheel or roller P, of the lever P,
being kept on to the cam O, and to assist in the return of the knife and wire frame.
The action of rotating the table J, is caused as shewn by a cam or eccentric T,
worked by the main shaft. E, having a wheel or roller bearing T, fitted and working
in the jaws of a side lever pivotted to the hind frame B³, having a horizontal connecting
rod V. and lever W, the fulcrum W' of the latter lever being at about the centre of
the Bed of the Machine and having a suitable ratchet or paw! X, fitted thereto, which
is caused to take alternately in the slotted portions Y, formed in the under part of the
rotating table J, and the said ratchet or pawl X, is caused to slide in and out of gear
and so causes the table to rotate or revolve.
Suitable bearings are provided in the hind frames B³, for the lower or driving
shaft Z, to work in, which carries a cog or toothed wheel Z, keyed upon it and gears
into a larger cog or toothed wheel Z2, fixed on the main shaft E. The driving shaft
may carry a balance or fly wheel and necessary pulleys for driving the same.
The entire machine may be driven either by hand, steanf or other power but the
details of construction may be varied especially as regards the methods of deriving
the various motions from the driving shaft, and in the case of employing internal
cams we may differently arrange the mechanical action likewise the springs referred
to, or dispense with them altogether.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what we
claim is
"In the combined mechanical action, or similar equivalents or mechanical actions,
for automatically producing complete Bricks direct from the Pug Mill and Hopper
unto delivery and ready for storage substantially in manner herein referred to illustrated
and described."
