Improvements in Presses for Bricks and other Blocks.
We, GEORGE WOOLLISCROFT, of Cornhill Cross, Leek, and HENRY TODD, of Brick
and Tile Works, Etruria, Stoke-on-Trent, both in the County of Stafford,
Brick and Tile Makers, 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:-
According to this invention the two ends of the block are pressed simultaneously -
and the block is then delivered automatically out of the mould.
Figure 1 is a side elevation of the press arranged for a coping block, Figure 2 is
an end elevation and Figure 3 a vertical transverse section. Figures 4 and 5 are
diagrams showing the parts in different positions.
C
a is a table having fixed to it two plates bb forming the two sides of the mould.
c and d are two plungers forming the ends of the mould and e and f are the top and
bottom. g is a shaft having fixed to it arms or cranks ggg. The shaft has
fixed to it the handle h and an arm j carrying a counterbalance weight j. k is a
bar free to move longitudinally in guides in the frame of the machine and
are rollers pivotted to it. The bar is connected by the slotted connecting rods ³
to the cranks g. The plunger c is connected by the rods c' to the upper ends of the
levers pivotted at to the bark and having thein lower ends connected by the
rods c to the cranks g¹. The plunger d is connected by the rods to the upper
ends of the levers 2 pivotted at d³ to the bark and having their lower ends con-
nected by the rods d to the cranks 2. The top e of the mould is fixed to a cross-
head e carried by side rods 2 fixed to the lower crosshead e³ upon which are
inclines acted on by the rollers are levers pivotted at e to the frame one
end of each of which carries a weight e whilst the other end enters a slot in the side
rods 3. The bottom of the mould is secured to the table a and on the underside
of the latter are inclines a' a' against which the rollers work.
When the parts are in the position shown at Figure 4 the block to be pressed
is placed on the table a between the plungers c and d and the handle h (which at
this time is vertical) is pulled down into the position shown at Figure 1 bringing
the parts into the position shown in Figure 5 and so pressing the block. On again
raising the handle the mould opens and block is pushed out endwise the parts
resuming the position shown at Figure 4.
In some cases the top e is fixed instead of being movable as shown.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:―
1. A press having two plungers which first approach each other and then separate
whilst moving in the same direction.
2. The method of actuating the plungers c and d substantially as described and
illustrated in the drawings.

page_text: 3. The combination with the subject matter of the preceding claims of t
moving top.
4. Presses substantially as described and illustrated in the drawings.
