Improvements in or relating to Pushing Apparatus Employed in.
what is known as a Brick Press.
We, JOHN JAMES FLETCHER of Carlton Villa, Lostock Park, Chorley New Road,
near Bolton, Brickmaker. and HERBERT BAXTER MARTIN of Black Bull Hotel,
69 Church Street, Horwich near Bolton, Engineer, bath in the County of Lancaster,
do hereby declare the nature of our said invention to be as follows:-
This invention consists in improvements in or relating to pushing apparatus
employed in what is known as a press for manufacturing bricks and consists in
means for providing a more direct and even push than hitherto, also for dispensing
with all waste, such as chopped ends and the like. On an oscillating shaft
mounted in bearings on the framework of the machine is fixed a lever the end of
which is attached to the pusher by means of a pin or centre. On the other end
or thereabouts of the before mentioned oscillating shaft is fixed a lever to which
is attached a connecting rod. The upper end of the latter is attached to the second
motion shaft of the machine, and is placed out of centre to give the requisite
motion. The second motion shaft is rotated by means of a spur wheel driven by a
pinion on the first motion shaft, the latter being provided with pulleys-fast and
loose-driven by a belt. This improved apparatus dispenses with several joints
hitherto employed, and is so arranged that the top piston of the machine cannot
catch or come in contact with the pusher. This invention is simple in construc-
tion and can be manufactured at a reduced cost than those now in operation.
This invention also allows of increased facilities for lubricating and repairs.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal side elevation of a brick press with our improvements
applied, and Fig. 2 a front elevation of same.
A is the framework of the machine; B first motion shaft; C second motion
shaft; D spur pinion; E spur wheel; F connecting rod; G oscillating frame; H
centre carrying oscillating frame; I connecting rod; J slide bars; K crosshead;
L fly-wheel; M driving pulley; 0 loose pulley; N strap fork; P strap fork rod,
and Q the table.
In both figures the same letters are employed to indicate corresponding parts.
The oscillating shaft R is mounted in the bearings S on the framework A of
the machine. On the oscillating shaft R is fixed or secured the lever T the upper
end of which is attached the pusher U by means of the pin or centre W. The a
pusher U slides to and fro on the table Q by means of the lever T mounted on the
oscillating shaft R. On the other end or thereabouts of the oscillating shaft R
is fixed the lever V provided with the swivelling nut X secured by the pins or
centres Y. To the swivelling nut X mounted in the jaw end of the lever V is
attached the connecting rod Z by means of the pin or centre A¹. The upper end 3
of the connecting rod Z is mounted on the pin B¹ attached to the disc C¹ mounted
on the second motion shaft C of the machine, and the pin B₁ is placed out of
centre as shown in the drawings to give the requisite motion to the lever V,
shaft R, lever T, and pusher U. The second motion shaft C is rotated by means of
the spur wheel E driven by the spur wheel 1) on the first motion shaft B; the 4
latter being provided with the loose pulley O and the fast pulley M driven by a
belt from any suitable or convenient position.
This invention operates as follows:-The clay block.or blocks S2 intended to be
operated upon is placed by the attendant on the table Q in front of the pusher U
as shown in Fig. 2 and as the cycle of operation of the machine is performed the 4
said clay block or blocks S3 is slid on the table Q to the position shown in dotted
lines and immediately under the sliding presser block M attached to the lower end
of the sliding crosshead K, by which the said clay block or blocks is pressed, after
which they are removed from the table Q in any convenient manner.
Having now particularly described and ascertained the nature of our said In- 5
vention and in what manner the same is to be performed we declare that what we
claim is:-
In combination with a brick press the use, construction, and combination of
parts forming our improvements in or relating to pushing apparatus employed,
