Improvements in or connected with Presses.
PAUL ARTHUR WINKLER, Merchant, at Leipzig, Auen Strasse, 20 Kingdom of
Saxony, German Empire, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement;-
My invention relates to improvements in or connected with presses and the
object of my invention is to provide a mould for a press, the walls or sides of
It
which cannot be disconnected from each other by the pressure of the press.
further consists of certain novel combinations and improved features, by means
of which air or moisture can escape from the pressed material into the open air.
In the accompanying drawings Figure 1 is a vertical section of the mould and
the head of the piston of the press. Figure 2 is a plan of the mould. Figures 3
and 4 show the section and the plan of a modification and Figure 5 is a section
of the base plate.
The mould consists of four walls or sides a joined to each other by means of
screw bolts and nuts b, as shown in Fig. 1 and 2, or by means of pins or bolts c
put through holes formed in the ends of the said four walls or sides, as shown in
Fig. 3 and 4. Two of the said walls or sides are provided with noses or shoulders &
catching in notches or grooves of the other two walls or sides and so preventing
the disconnection of the four walls or sides while the machine is performing its
work.
Upon the table e of the press is arranged the base plate f and upon the latter
the mould receiving the material g to be pressed by the machine. Upon the said
mould is placed the pressing plate h, on which the head of the piston of the
press or machine operates for squeezing up the said material. The base plate f
and the pressing plate are provided with holes opening into grooves arranged
at the upper surface of the pressing plate h and at the lower surface of the base
plate fin such a manner that the air or moisture of the said material can escape
into the open air, while the head of the piston of the press or machine operates
the pressing plate of the mould.
Having now particularly described 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 mould consisting of four walls or sides, connected to each other by means
of screw bolts, and provided with noses or shoulders and notches or grooves catch-
ing in each other, substantially as described and shown in Figures 1 and 2.
2. A mould consisting of four walls or sides connected to each other by means
of pins or bolts put through holes formed in the ends of the said walls, and provided
with noses or shoulders and notches or grooves catching in each other, substan-
tially as described and shown in Figures 3 and 4.
3. The combination of a mould substantially as described, with a base plate
and a pressing plate, the base plate and pressing plate being provided with holes

page_text: opening into the upper surface of the pressing plate and into the lower surface
of the base plate, substantially as and for the purpose set forth.
4. The new or improved mould for presses, substantially as described and set
forth in the accompanying specification and drawing.
