The object of my invertion is the improvement of machines for the manufacture of
ornamental and shape brick, tiles, and other similar clay products, and for re-pressing
brick and other articles made from clays, by rendering the same more simple and
efficient in construction and operation.
It consists in the features and combinations of features hereinafter described.
The machine is placed on wheels to facilitate its movement from place to place.
The frame of the machine consists of the bed-plate A, standards or housings A' and
a top cross-cap A². is a screw engaging with a screw-boss c¹ on cross-cap A* and
provided with weighted arms C2, by which the same is rotated. The lower end of:
the screw engages with a movable cross-head D, and rotates freely in a.recess in said
cross-head, so as to be raised and lowered without rotating the latter. E is. a short
plunger bolted to the cross-head D, provided with a steel face-plate, and adapted to fit
neatly within a mould-box F. The cross-head D slides on guide rods ( secured, to the
top and bottom cross-plates.
1.
The mould-box is provided with a steel lining, and is cast in one piece with lugs f,
through which the guide-rods C pass and slide. The mould-box rests upon springs G.
These springs encircle the rods C³, and are set on collars H, and the collars are
secured to the rods by means of set-screws I, I. The force of the compression of the
springs against the mould-box is regulated by a proper setting of the collars on the
rods.

The movement of the mould-box on rods C, for the purpose hereinafter described,
is limited by means of slots 0³, engaging with pins C4, on rods (.
K are adjustable suspension rods secured to cross-head D, passing loosely through
lugsf, of the mould-box, and are forked at their lower ends. Between these forks are
hung on a pin j, spring hoisting-grips L. These grips consist each of a single
piece of stiff spring steel bent at the centre to form two arms of equal length and
terminating in inwardly projecting jaws or hooks I, I. They are hung on pin at
their bend, and are provided with cheeks m, m, one on the inner side of each

spread apart when the cheeks m engage therewith, as hereinafter described. They
are cast on collars m³, which are set by screws m³ to regulate the matter of tripping
as to time.
arm.
The rods K are made adjustable as to length by means of nuts n.
O is a lower cross-head placed through and guided by slots 0¹, formed in a
stationary box P, olted to the bed-plate. 02 are projecting lugs in the cross-
head with which the hook I, I, of the grippers L, are adapted to engage,

page_text: Qis the lower plunger, connected to cross-head O, moving within and guided
by the box P, and provided with a steel pressure face-plate q.
The lugs on the mould-box are provided with blocks t, against which the upper
cross-head presses to force the mould-box down as and for the purpose hereinafter
specified.
The operation of the machine is as follows:-
The brick or other article to be pressed is fed into the mould-box from platform pl
and rests upon the top of the lower plunger, which, in effect, constitutes the
bottom of the mold-box."
Then, by turning the screw by the weighted handles, the upper cross-head and
follower are carried down on rods C¹. The follower is forced against the brick,
and the latter against the lower plunger, and so far as the mere fact of repressing
the body of the brick is concerned, the operation is now completed. But the down-
ward pressure of the upper cross-head being continued, the mould-box is forced down
by the pressure of the cross-head on the projection t, on to the springs on which it
rests, until stopped by the pin C on rods (1. This additional pressure forces the
mould-box down along the sides and ends of the brick, thus smoothing the sides and
ends, and further solidifying the edges.
In the meantime, while the upper plunger is descending, the gripper arms have
been carried down and their hooks engaged with the projecting blocks on the
lower cross-head, and when the screw is rotated in the opposite direction, to carry
the upper plunger up, the lower plunger is raised until the brick, or other article,
is carried above the mould-box and to a level with the platform, when it is
removed. The cheeks on the gripper arms then come in contact with the lugs m³
on the rods (, are forced apart, and the lower plunger and cross-head thus dis-
engaged from the grippers are permitted to fall by gravity. The mould-box, when
the pressure of the upper cross-head is relieved therefrom, is forced up to its
normal position under the upper plunger by the action of the springs on which it
rests, again smoothing the sides and ends of the brick.
It will thus be seen that the entire operation of moulding, re-pressing and presenting
the article for discharge is performed by the action of the screw lever.
It will be noticed that the mould-box is placed flat, and not edgewise, on its
supporting springs between the plungers, and that the brick is placed and pressed
therein in a corresponding position; and also that the mould-box does not move
against the stationary box enclosing the lower plunger, but that, as shown in Fig. 1,
which represents the apparatus at the close of the operation the mould-box is always
held above contact with the stationary box, and the top of the lower plunger is
always within the mould-box.
It is obvious that my machine may be put to other uses than re-pressing brick,
and that it may be used for moulding brick or other articles inade from clays or
other plastic material.

Improvements in Machinery or Apparatus for the Manufacture of
Articles such as Bricks.

America, Lawyer.
I, WILLIAM LLOYD WISE of No. 46 Lincoln's Inn Fields in the County of
London,. Consulting Engineer and Patent Agent 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 this invention is the improvement of machines for the manufacture

page_text: of ornamental and shape brick, tiles, and other similar clay products, and for repress-
ing brick and other articles made from clays, by rendering the same more simple and
efficient in construction and operation.
It consists in the features and combinations of features hereinafter described and
claimed; and is illustrated in the drawings filed with the Provisional Specification, in
which:
Fig. 1 is a view in elevation of the front end of the machine ;
Fig. 2 is a vertical section of the same on the line x-x of Fig. 1 ; and
Figs. 3, 4, 5, 6 and 7 are details.
The
The machine is placed on wheels to facilitate its movement from place to place.
frame of the machine consists of the bed-plate A, standards or housings A¹, and a
top cross-cap A². C is a screw engaging with a screw-boss c¹ on cross-cap A2, and
provided with weighted arms (3, by which the same is rotated. The lower end of
the screw engages with a movable cross-head D, and rotates freely in a recess in said
cross-head, so as to be raised and lowered without rotating the latter. E is a short
plunger bolted to the cross-head D, provided with a steel face-plate, and adapted to
fit neatly within a mould-box F. The cross-head D slides on guide rods secured to
the top and bottom cross-plates.
The mould-box is provided with a steel lining, and is cast in one piece with lugs f,
through which the guide rods C³ pass and slide. The mould-box rests upon springs G.
These springs encircle the rods (₁, and are set on collars H, and the collars are
secured to the rods by means of set screws 1, I. The force of the compression of
the springs against the mould-box is regulated by a proper setting of the collars on the
rods.
The movement of the mould-box on rods C, for the purpose hereinafter described, is
limited by means of slots C³, engaging with pins (, on rods C¹.
K are adjustable suspension rods secured to cross-bead D, passing loosely through
lugs f, of the mould-box, and are forked at their lower ends. Between these forks
are hung on a pin j, spring hoisting-grips L. These grips consist each of a single
piece of stiff spring steel bent at the centre to form two arms of equal length and
terminating in inwardly projecting jaws or hooks l, l. They are hung on pinj at
their bend, and are provided with cheeks m, m, one on the inner side of each arm.
m² are pear-shaped adjustable projections on rods C', by which the grips are spread
apart when the cheeks m engage therewith, as hereinafter described. They are cast
on collars m³, which are set by screws m³ to regulate the matter of tripping as to
time. The rods K are made adjustable as to length by means of nuts n.
lower cross-head placed through and guided by slots O', formed in a stationary box P,
O is a
bolted to the bed plate. 02 are projecting lngs in the cross-head with which the
hooks I, 1, of the grippers L, are adapted to engage. Q is the lower plunger, con-
nected to cross-head O, moving within and guided by the box P, and provided with a
steel pressure face-plate q. The lugs on the mould-box are provided with blocks t,
against which the upper cross-head presses to force the mould-box down as and for the
purpose hereinafter specified.
The operation of the machine is as follows
The brick or other article to be pressed is fed into the mould-box from platform p¹,
and rests upon the top of the lower plunger, which, in effect, constitutes the bottom of
the mould-box. Then by turning the screw by the weighted handles, the upper cross-
head and follower are carried down on rods C. The follower is forced against the
brick, and the latter against the lower plunger, and so far as the mere fact of
re-pressing the body of the brick is concerned, the operation is now completed. But
the downward pressure of the upper-cross-head being continued, the mould-box is
forced down by the pressure of the cross-head on the projection t, on to the springs
on which it rests; until stopped by the pins or rods C'. This additional pressure forces
he mould-box down along the sides and ends of the brick, thus smoothing the sides
and ends, and further solidifying the edges. In the meantime, while the upper plunger is
lescending, the gripper arms have been carried down and their hooks engaged with
he projecting blocks on the lower cross-head, and when the screw is rotated in the

page_text: opposite direction, to carry the upper plunger up, the lower plunger is raised until the
brick, or other article, is carried above the mould-box and to a level with the platform, when
it is removed. The cheeks on the gripper arms then come in contact with the lugs m¹
on the rods C¹, are forced apart, and the lower plunger and cross-head thus disengaged
from the grippers are permitted to fall by gravity. The mould-box, when the pressure
of the upper cross-head is relieved therefrom, is forced up to its normal position
under the upper plunger by the action of the springs on which it rests, again smoothing
the sides and ends of the brick.
It will thus be seen that the entire operation of moulding, re-pressing and presenting
the article for discharge is performed by the action of the screw lever.
It will be noticed that the mould-box is placed flat, and not edgewise, on its sup-
porting springs between the plungers, and that the brick is placed and pressed therein
in a corresponding position; and also that the mould-box does not move against the
stationary box enclosing the lower plunger, but that, as shown in Fig. 1, which
represents the apparatus at the close of the operation, the mould-box is always held
above contact with the stationary box, and the top of the lower plunger is always within
the mould-box.
It is obvious that my machine may be put to other uses than re-pressing brick, and
that it may be used for moulding brick or other articles made from clays or other
plastic material.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination, in a re-pressing and moulding machine, with the frame, of a
sliding mould-box, the guide rods on which the said box slides, springs on said rods
pressing against said mould-box, a cross-head and upper plunger, and a screw secured
to said cross-head, substantially as and for the purpose specified.
2. The combination with the frame, of the guide rods, the adjustable spiral springs
on said rods, and the mould-box sliding on said rods, and supported by said springs,
substantially as and for the purpose described.
3. The sliding mould-box provided with the lags f and slots C³, in combination
with the guide rods C passing through said lugs, and pins C on the rods to limit
the movement of the box on said rods in connection with the slots, substantially as
described.
4. In combination with the stationary lower plunger-box provided with slots in
its sides, the lower-cross-head extending through said slots, the rods provided with
grips to engage with said cross-head, the plunger within said box secured to said
cross-head, and means for raising said grippers and cross-head, substantially as
described.
5. The combination with the rods, such as C', provided with the pear-shaped
projections, the suspension-rods, the grippers hung on the latter, and provided with
the cheeks to engage with said projections, whereby the grippers are spread apart
the upper cross-head to which the suspension rods are secured, and means for raising
and lowering said cross-head, substantially as described.
i
6. The combination of the upper cross-head, plunger and screw, with the mould-boy
provided with lugs and upper extending projections, whereby, when the plunger i
forced down into the mould-box its entire length, the mould-box will be forced furthe
down by the cross-head, substantially as and for the purpose described.
Lastly. I claim the improved machine for making articles such as brick constructe
arranged and operating as hereinabove described and shown.
