PROVISIONAL SPECIFICATION..
Improved Machinery or Apparatus for Moulding and Pressing Bricks
and the like.
I, RICHARD SCHOLEFIELD, of Burley Vale Mills, Kirkstall Road, Leeds, in the
County of York, Engineer and Patent Brick Machine Maker do hereby declare
the nature of this invention to be as follows:
'
Hitherto in the manufacture of bricks it has been usual to pass the bricks
manually from the cylinder moulding machine on to a separate pressing machine.
The object of my invention is to provide a machine combining the moulding and
pressing operations; the bricks being passed mechanically from the moulding
cylinder to the pressing apparatus.
In carrying out my said object I employ a suitable frame in which is fitted or
mounted the cylinder moulding arrangement together with ram and crank and other
parts. The said crank is so constructed as to give motion to the pressing apparatus
as well as the ram of the cylinder moulding arrangement, or the necessary motion
may be imparted otherwise."
The pressing apparatus may consist of a plunger, ram or piston actuated by the
crank as aforesaid, or otherwise, and a fixed or travelling end or block between
which and the said plunger, ram, or piston the brick is pressed.
The bricks are passed from the moulding cylinder to the pressing apparatus by
any suitable means.
Further my said invention is applicable for the moulding and pressing, in the
manner set forth, of articles similar in kind to bricks.

COMPLETE SPECIFICATION.
Improved Machinery or Apparatus for Moulding and Pressing Bricks
and the like.
I, RICHARD SCHOLEFIELD, of Burley Vale Mills, Kirkstall Road, Leeds, in the
County of York, Engineer and Patent Brick Machine Maker, do hereby declare
the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement :-
Hitherto in the manufacture of bricks it has been usual to pass the bricks
manually from the cylinder moulding machine on to a separate pressing machine.
The object of my invention is to provide a machine combining the moulding
and pressing operations, the bricks being passed mechanically from the moulding
cylinder to the pressing apparatus.

page_text: In carrying out my invention I employ a frame A, which has a division portion A',
so forming the machine into two parts, one for moulding or shaping the brick or other
article, and the other for pressing the brick or other article after it has been so
shaped or formed. The moulding or shaping arrangement consists of cylinder B
(mounted within frame A) 'having dies C, ram D, connected with crank E upon
crank shaft F. The hopper G for feeding the material being arranged over the
cylinder B, in the well known manner. The said crank shaft F gives motion to
the pressing apparatus as well as to the ram of the moulding arrangement.
The pressing apparatus consists of a piston or ram H actuated by the crank J
upon crank shaft F, and die H', free to move (as hereinafter set forth) within the
chamber H2, a similar die H³ being fixed to or upon the end or block I, which is
caused to move backwards and forwards by the movement of the ram H to which it
is connected by means of the rods M.
:
The mechanical arrangement for passing the bricks from the moulding to the
pressing apparatus consists of a platform N upon which is a sliding piece or pusher O,
connected by levers or rods P and P¹ to a centre R from which it receives its
motion, which is given by means of lever S, connected with the upright rod S', and
horizontal lever or rod S2, connected with a cam S³, fastened to a gear wheel T
upon the crank shaft F. U is a rod fastened to gear wheel T having a catch U¹,
which engages with pins or teeth U, in or connected with the lantern or pin
wheel U³, whereby the revolution of the moulding cylinder is regulated or con-
trolled in the required manner. The machine is driven by pulleys V, upon driving
shaft W, upon which are pinions W', gearing with wheels T upon the crank shaft F.
X is a table for receiving the bricks or like articles after being pressed.
The action is as follows:-
After the clay is fed into the machine by means of the hopper G, it is
pressed forward into the moulding cylinder B, by means of the feed plunger or
ram D, which gives one pressure to the brick or other article; the cylinder B
then rotates one quarter of a revolution (such revolution being controlled by the
lantern or pin wheel and parts connected therewith) and the brick or other
article is brought under another plunger or presser Z (operated by lever
arrangement Z from crank shaft F) and accordingly receives a second pressure,
the moulding cylinder then rotates another quarter of a revolution, and the
brick is. then delivered in front of the sliding piece or pusher O, which pushes
the brick along the platform N until in front of the pressing arrangement; the
die H is then at the front of the chamber H, having been moved there by
the forward movement of the piston or ram H. On the return stroke of the
said ram H, the block or end L is caused to travel towards the chamber H,
the die H³ pushing the brick or other article before it, and against the dic H'
which is thereby caused to move backwards in the chamber H2 until the
die H comes in contact with the plate H, where it stops, and offers the required
resistance to the pressure exerted by the end or block L, in pressing the brick
or other article; the piston or ram H continues to the end of its stroke, and
then reverses, and on its forward movement pushes the die H₁ back again to the
front of the chamber H, where the brick or other article is delivered upon
the standing table ✗ ready to be placed on the barrow and removed for
burning in the required manner.
Further my said invention is applicable for the moulding and pressing, in the
manner set forth, of articles similar in kind to bricks, by altering the moulds or
'dies as required.
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. A machine for moulding and pressing bricks and the like articles, in which the
articles after being moulded or shaped are mechanically passed from the moulding
portion of the machine to a pressing arrangement, substantially as set forth.

page_text: 2. In a machine for moulding and pressing bricks and the like articles, the
combination of apparatus for moulding or shaping the articles, and apparatus for
pressing such after being so moulded or formed, together with a mechanical
arrangement for passing the articles from the moulding to the pressing apparatus,
substantially as set forth.
3. In machinery for moulding and pressing bricks and the like articles, the
employment of apparatus for mechanically passing the bricks or the like articles
from the moulding to the pressing apparatus, substantially as set forth.
