PROVISIONAL SPECIFICATION.
Improved Machinery or Apparatus for Moulding and Pressing
Bricks, Soap Tablets, and the like.
I, WILLIAM ARTHUR GILL, Engineer, of Holbeck Lane, in the City of Leeds,
do hereby declare the nature of this invention, to be as follows:-
My invention has reference to improved machinery or apparatus for moulding
and pressing bricks, soap tablets, and the like.
According to my invention I employ a table having series of moulds arranged
therein, this table is carried upon a vertical shaft rotating in a step or bearing (at
its lower end) upon the foundation plate of the machine.
Above the said table are the dies or presser blocks connected by a shaft or shafts
to cranks upon a horizontal shaft supported in pedestals upon the frame of the
machine. The end of the said shaft carries a bevel wheel which gears with another
bevel wheel upon a vertical shaft, the lower end of which works in a step or bearing
upon the foundation plate of the machine.
This vertical shaft carries a pin wheel or wheel with a pin or pins adapted to
engage in slots upon a star wheel upon the other vertical shaft rotating the moulding
table so as to move the said table or bring the moulds into position for the dies or
presser blocks to impart their pressing action, and then, when the crank reverses
and withdraws the dies or presser blocks after the pressing action, to allow the
table to move or turn and bring the next moulds into position for the action of the
dies or presser blocks, at the same time the panels of the other moulds are raised
by runners, rods, and inclined planes so as to bring the brick or other pressed
material to the top of its mould ready for removal.
The dies or presser blocks are preferably carried by sliding brackets upon the
faces of the frame.
The dies or presser blocks are also provided with an india-rubber or other elastic
cushion to compensate for or regulate the pressure according to the thickness of the
substance to be pressed.
In lieu of imparting motion to the dies or presser blocks by the mechanism
aforesaid I may employ toggle mechanism for that purpose.

COMPLETE SPECIFICATION.
Improved Machinery or Apparatus for Moulding and Pressing
Bricks, Soap Tablets, and the like.
I, WILLIAM ARTHUR GILL, Engineer, of Holbeck Lane, in the City of Leeds,
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 :-
My invention has reference to improved machinery or apparatus for moulding
and pressing bricke Soon tablets and the like

page_text: Fig. 1, is a front elevation of
Fig. 2, is a plan.
my invention.
Fig. 3, is a detail view of cam mechanism for imparting the pressing action to the
dies or presser blocks.
According to my invention I employ a table A having a series of moulds B
arranged therein, this table A is carried upon a vertical shaft C rotating in a step
or bearing D (at its lower end) upon the foundation plate E of the machine.
Above the said table A are the dies or presser blocks F connected, as hereinafter
explained, by shafts or rods to cranks, or cams, upon a horizontal shaft G supported
in pedestals H upon the frame of the machine.
The end of the said shaft G carries a bevel wheel K which gears with another
bevel wheel L upon a vertical shaft M the lower end of which works in a step or
bearing N upon the foundation plate E of the machine.
This vertical shaft M carries a pin wheel, or wheel O with a pin or pins P, adapted
to engage in slots R upon a star wheel S upon the other vertical shaft C rotating
the moulding table A, so as to move the said table or bring the moulds B into
position for the dies or presser blocks F to impart their pressing action, and then
when the crank reverses (or the action of the cams in lieu thereof) and withdraws
the dies or presser blocks F after the pressing action, to allow the table A to move
or turn, and bring the next moulds B into position for the action of the dies or
presser blocks F, at the same time the panels B' of the other moulds are raised by
runners T, rods U, and inclined planes V so as to bring the brick or other pressed
material to the top of its mould, ready for removal.
The dies or presser blocks F are preferably carried by sliding brackets W
adapted to slide upon the faces X of the frame .J.
The dies or presser blocks F are also provided with an india-rubber or other
elastic cushion such as a rubber ring or spiral spring to compensate for or regulate
the pressure according to the thickness of the substance to be pressed.
In the drawing annexed, the dies or presser blocks F are shown as operated by
cam mechanism, by which means the dies or presser blocks F receive a direct
"drop" pressure by means of weights.
Each brick or tablet receiving a double pressure by means of the double cams at
each revolution.
Referring to the said drawings, the dies or presser blocks F are joined to the
sliding brackets W, to which rods F' are also connected, these rods pass upward
through blocks F and are secured by lock-nuts F³.
Upon the said blocks F are guide spindles F by which weights can be held
upon the top of the said blocks for giving the "drop" pressure referred to.
Passing through the said block F² is a pin or stud F's upon the ends of which are
runners F immediately over cams F7 upon the horizontal shaft G. F are rubber
washers between flanges F' and washers F10, to compensate for concussion on the
rods F' during the pressing action.
Instead of using weights upon the blocks F2 spiral springs may be arranged
thereon to work against abutments so that on the lifting up of the blocks by the
action of the cams upon the runners, the said springs would be compressed, and on
the cams clearing the runners the springs would expand and force the dies or presser
blocks down again to give the pressing action.
In
Or crank motion may be employed for operating the dies or presser blocks.
this case the shaft G is cranked and connecting rods pass from the said cranks to
the dies or presser blocks which are joined to the sliding blocks.
In lieu of imparting motion to the dies or presser blocks by the mechanism
aforesaid, I may employ toggle mechanism for that purpose.
1
The machine or apparatus is driven by belt upon fast pulley Y. Z being the
loose pulley. Both the said pulleys are upon a shaft Z' carried in bearing Z² bolted
on the frame J, and bracket arm Ź³.

page_text: Upon the said shaft Z' is a pinion Z which gears with a spur wheel Z' upon the
horizontal shaft G, by which motion is given to the said shaft G, and through it to
the other parts.
A are runners for the moulding table A to revolve on, they are carried on pins
or studs A passing through brackets A³ on the frame J.
Z is a hand wheel upon the shaft Z1 for rotating the moulding table so that the
moulds are alternately brought away from the dies or presser blocks and can have
the tablets or material to be pressed placed therein.
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 claim is :-
1. A machine or apparatus for moulding and pressing bricks, soap tablets, and
the like, having a table A with moulds B therein, dies or presser blocks F operating
from a shaft G above the said table, a pin wheel O upon a shaft M deriving its
motion from the shaft G, and a star shaped wheel S, upon the same shaft C as the
said table A, and engaging and disengaging with the said wheel O, in the manner
and for the purposes, substantially as set forth.
2. A machine or apparatus for moulding and pressing bricks, soap tablets, and
the like, having a table A with moulds B therein, dies or presser blocks F, operated
from a shaft G above the said table, a pin wheel O upon a shaft M deriving its
motion from the shaft G, a star shaped wheel S (upon the same shaft C as the table A)
and mechanism for automatically raising the panels B₁ of the moulds, (so that the
moulded and pressed material is expelled) and, on the continued movement of the
table A, the panels are again lowered to their normal positions, substantially as set
forth.
3. In a machine or apparatus for moulding and pressing bricks, soap tablets, and
the like, the combination with the table A having moulds B therein, of dies or
presser blocks F, operating in the manner and for the purposes set forth.
4. In a machine or apparatus for moulding and pressing bricks, soap tablets, and
the like, the combination with the table A and dies or presser blocks F, of cams F
carried upon a shaft G, substantially as and for the purposes shown and described.
5. In a machine or apparatus for moulding and pressing bricks, soap tablets, and
the like, the combination with the table A of dies or presser blocks F connected by
rods to cranks upon a horizontal shaft, and operating as and for the purposes set
forth.
