Improvements in and relating to Brick-making Machines.
I, THOMAS PARKER, of Copeley Hill, Erdington, in the County of Warwick,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention consists in the improved mechanism for the production of bricks.
as hereinafter set forth.
I provide two side standards secured in a vertical position to carry the revolving
mechanism.
I next provide a main shaft or axis. I then provide the revolving mechanism,
which consists of a drum-shaped arrangement formed with two outer spur wheels;
within such drum-shaped structure are provided two, three, four or more carriers,
each carrier is pivotted near the under side of the drum rim; within the back
part of the carrier is mounted a roller capable of easy revolution over its axis.
I next provide two cam-plates the configuration of which conforms to a semi-
circle or thereabouts, the outer periphery of the circle terminating inwards in
the form of easy curves.
I next provide a feeding trough, the mouth of which is constructed to extend
one foot, 2 feet or more above and beyond the revolving drum; this feeding trough
is extended in a circular form round the drum mechanism to the under side
thereof so as to deliver the clay into the brick die.
In putting together the several parts hereinbefore described I place one cam-
plate against the boss of inner standard, I next mount the central drum against
the first cam-plate, I then mount the second cam-plate against the boss of drum ;
I then pass the shaft or main axis through one standard, thence through one cam-
plate into the drum boss and forward through the other cam-plate passing out
through the second standard, the two cam-plates are keyed or otherwise secured
tightly on to the shaft and the shaft is keyed or otherwise secured firmly within
the side standards, so that the cam-plates remain stationary and the drum with
its carriers revolves over the fixed shaft.
In using my improved mechanism as hereinbefore described a pair of pinions
would be mounted to gear into the drum toothed wheels, such driving pinions
would be actuated by a shaft carried to any convenient motor; the revolution
of the driving shaft transmitting power from the pinions to continuously revolve
the drum and its carriers.
By feeding clay or other material into the feeding trough the same is carried
by means of the projecting faces of the carriers through the circular downward
passage of the feeding trough into the brick die or into the tube leading to the
brick die; as each carrier reached the lower side of the drum the cam-plate only
reaching half way across the drum would by the revolution of the drum pass out
of contact with the back end of carrier, consequently the face of the carrier in
striking against the bottom delivery tube would turn on its axis within the drum,.
and remain therein during the upward half turn of the drum when the back end
of the carrier would again come in contact with the fixed cam-plate and be

page_text: thereby pushed outwards and supported in its working position, the continuous
revolution of the drum on the fixed axis produces a continuous automatic action
of the carriers against the clay put into the trough or hopper.

Improvements in and relating to Brick-making Machines.
I, THOMAS PARKER, of Copeley Hill, Erdington, in the County of Warwick,
Mechanical Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
This invention consists of the hereindescribed improvements in and relating
to brick making machines.
I will describe my invention by referring to the accompanying drawings on
which Fig. I is a side elevation of a brick making machine constructed according
to this invention; Fig. 2 shews a part of the said machine separately; Fig. 3 is
a side elevation of the said machine with one of the side standards removed;
Fig. 4 is a front view of the machine; Fig. 5 is a sectional side elevation of the
same and Fig. 6 is a cross sectional elevation of the same.
The same letters of reference indicate the same parts in all the Figures.
In carrying out my invention I provide two side standards A1 A2 fixed on to a
base B and carrying between them a horizontal main axis C on which is mounted
the revolving mechanism which consists of the metal drum D provided with:
arms d' and a central boss d²' so as to turn upon the central shaft C. Fixed to or
formed with the sides of this drum D there are two spur wheels E¹ E³ gearing
with pinions on a countershaft F by which the drum D receives a slow rotary
movement in the direction indicated by the arrows in Figs. 1, 3, and 5.
The
drum D carries any convenient number of carriers G say four as shewn (one of
which is shewn separately by Fig. 2). Each carrier G is made of metal of about
the same width as the space between the flanges of the drum D and is made
with side ears g¹ g2 through which passes a cross pin g³ and through the flanges
of the drum D so as to secure the carrier thereto and about which the carrier can
turn. In the periphery of the drum D there is for each carrier a hole d³ of the 3
proper size to allow of the carrier projecting through the same. One face
namely g of each carrier G is made flat so that when the carrier G is turned to
project upwardly from the periphery of the drum D this face g forms a continua-
tion of a radius of the drum, the other face 95 of the carrier G is made in the
form of an are of a circle of which the pin g³ is the centre. This arc shaped 4
part go terminates in two cars 96 g which between them carry the roller 98 which
turns on the pin 99 passing through the ears g6 g the object of this roller being
to act upon the cam plates. H1 H2 which are mounted and fixed upon the
stationary shaft C. The outer surface h¹ of each of these cam plates H¹ H² is
nearly a semicircle (see Figs. 3 and 5) terminating by easy curves at h³ h³ the 4
outline being continued inwards to the central boss h*. Fixed above and adjacent
to the drum D is a clay feeding trough I which at the bottom i terminates in a
partly circular trough 2 fixed on the base B and which fits against the drum D
and is constructed to extend beyond the periphery of the drum D to about the

page_text: same distance as the carriers G extend beyond it when they are turned to their
outward position. This is clearly shewn by Fig. 5.
The cam plates H¹ H³ are keyed on the shaft C which is also keyed in the
standards A A2 so as to remain stationary while the drum D and carriers G
revolve about the same.
The machine above described acts as follows:-As the drum D revolves in the
direction indicated by the arrows in Figs. 1, 3, and 5, the carriers G are by their
rollers acting on the stationary cam plates H₁ H2 caused to turn about their
pins 3 immediately the opening d³ has arrived below the inside of the right hand
side of the feeding trough I as shewn in Figs. 3 and 5, so that the carrier G is
by the cam plates H H turned outwardly and projects through the opening ³
and acts upon the clay in the feeding trough I and carries the same along and
down the lower part of the feeding trough into the brick die or into the tube J
leading to the brick die. As each carrier G reaches the lower side of the drum D
the roller g of the carrier passes out, of contact with the termination h² of the
cams HH2 and then the face g of the carrier strikes against the end of the
delivery tube J and turns the carrier G about its axis g³ so that the carrier G
then occupies a position within the drum D as shewn on the right hand side of
Figs. 3 and 5 and there remains during the upward half turn of the drum D until
when the roller of the carrier again comes into contact with the cam
plates H¹ H2 by which the carrier G is again pushed outwardly and by the
circular face h of the cam plates H H the carriers are supported in their working
positions and thus the continuous revolutions of the drum D) with its carriers
about the fixed axis C produce a continuous action of the carriers G against the
clay in the trough I and force the same through the delivery pipe J or brick die
in a continuous stream. to be cut up into bricks or otherwise treated by means
forming no part of my invention.
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 a brick making machine, the employment of the mechanism herein
described for forcing the clay along the feeding trough so as to deliver the same
in a continuous stream through the brick die or delivery tube, said mechanism
consisting essentially of a revolving drum the periphery of which fits against the
feeding trough and is provided internally with carriers G so jointed to the
interior of the drum so as to either turn outwardly and project from the periphery
of the drum or turn inwardly within the same in combination with a stationary
cam or cams within the drum all so arranged that as the drum revolves the
carriers are by acting on the said cam or cams caused to project into the feeding
trough and carry the clay round and force it along the same and through the
brick die or delivery tube and when the carriers reach the brick die or delivery
tube they turn inwardly within the periphery of the drum, substantially as
described.
2. A brick making machine provided with mechanism constructed and arranged
substantially as herein before described and illustrated by the accompanying
drawings for forcing the clay from the feeding trough in a continuous stream
through the brick die or delivery tube.
