I HARRY HEATLY of 98 Cecil Street Manchester, in the County of Lancaster
Engineer, do hereby declare the nature of the said invention to be as follows:-
•
My invention relates to mechanism or apparatus for applying pressure for copying
letters and other documents which are written or printed by ink from which a copy or
copies may be taken on suitable damp paper by pressure, which apparatus may also
be used where pressure is required for other purposes.
My invention is designed and is more particularly applicable as a portable press as
it is easily carried about along with ordinary luggage when travelling though it may
be arranged for Office and other purposes as a fixture.
My invention consists in forming a partial vacuum within enclosed diaphragms, so
that the pressure of the external atmosphere will act upon the diaphragms, and bring
them towards each other the letter copy book or other object to be acted upon being
first placed between the diaphragmns.
The mode of carrying out my invention will be better understood by the following
explanation of the manner and apparatus for applying it as an arrangement for copying
letters and other documents in which arrangements my invention also consist.-Two
boards of wood or other suitable material are used which are connected to a square
flat air tight bag closed on three sides but with one side open.
The letter copying book to be put under pressure is inserted through the openside
of the bag the two edges of which are then brought and held together by a spring) or
other clip. A small pump formed in any convenient manner but by preference like a
pair of bellows, is attached to one diaphragm, which bellows has an inlet and outlet
Prins 77

page_text: valve, and the inlet valve communicates with the interior of the bag, and the outlet
valve with the exterior atmosphere.
By a few strokes of the bellows or pump a part of the air is exhausted from the bag
and the external pressure of the atmosphere acts upon the boards or diaphragms and
this puts pressure upon the book.
The air may be admitted into the bag by removing the clip, or by opening a valve
to allow it to enter.
When the press is used as a stationary fixture the bag is or may be exhausted by a
communication with any suitable pump or apparatus for exhausting air or forming a
partial vacuum.
COMPLETE SPECIFICATION.
Improvements in Presses for Copying and other Purposes.
I HARRY HEATLY of .98 Cecil Street Manchester, in the County of Lancaster,
Engineer, 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 relates to mechanism or apparatus for applying pressure for copying
letters and other documents which are written or printed by ink from which a copy
or copies may be taken on suitable damp paper by pressure, which apparatus may also be
used where pressure is required for other purposes.
My invention is designed and is more particularly applicable as a portable press as
it is easily carried about along with ordinary luggage when travelling, though it may
be arranged for Office and other purposes as a fixture.
My invention consists in forming a partial vacuum within enclosed diaphragms, so
that the pressure of the external atmosphere will act upon the diaphragms, and bring
them towards each other the letter copy book or other object to be acted upon being
first placed between the diaphragms.

page_text: The mode of carrying out my invention will be better understood by the following
explanation of the manner and apparatus for applying it as an arrangement for
copying letters and other documents in which arrangements my invention also consist-
Two boards of wood or other suitable material are used which are connected to a
square flat air tight bag closed on three sides but with one side open.
The letter copying book to be put under pressure is inserted through the openside
of the bag the two edges of which are then brought and held together by a spring or
other clip. A small pump formed in any convenient manner is attached to one
diaphragm, which pump has an inlet and outlet valve and the inlet valve communicates
with the interior of the bag, and the outlet valve with the exterior atmosphere.
By a few strokes of the pump a part of the air is exhausted from the bag and
the external pressure of the atmosphere acts upon the boards or diaphragms and this
puts pressure upon the book.
The air may be admitted into the bag by removing the clip, or by opening a valve
to allow it to enter.
When the press is used as a stationary fixture the bag is or may be exhausted by a
communication with any suitable pump or apparatus for exhausting air or forming a
partial vacuum.
Fig. 1, is a plan view, fig. 2 is a section on line A-B fig. 1 and fig. 3 a section on
line CD fig. 1 of a portable copying press with pump complete.
Fig. 4 is a plan view and fig. 5 a section on line E-F fig. 1, of another modification
where a separate pump is or may be used.
Fig. 6 is a section illustrating another modification.
a, is a bag closed on all sides except one made of any suitable strong and flexible
material which is air tight such as canvas and india rubber.
The inside of the upper side of the bag has a plate 6 of wood or any suitable
material secured to it. To one lip of the open side of the flexible bag a bar e of wood
or other suitable material is secured, to the concave side of which bar a pump barrel d
is attached, and this pump barrel communicates at one end by a pipe d' through a
hole in the bag (with which the pipe d¹ is made air tight by a flange) with the interior
of the bag.
The surface of the plate b on its under side is or may be grooved or fluted to allow
the air to be drawn away.
In the pump barrel d there is a piston or bracket d² and rod d³ which has a
handle d at its outer end for working the pump.
to
The piston or bucket has a valve or clack d in it; and there is a ball valve
prevent the return of the air when the pump makes its inward stroke. The lower
lip of the open side of the bag is secured to a bar f of wood or other suitable material
with a layer of india rubber or other elastic material between the bar and lip.
There is a hook g jointed at g' to each end of the bar f which when the lips of the
bag are brought close together can be made to hook upon studs or eyes c¹ formed at
the end of the bar c attached to the pump barrel d.
In using this press the book a in which the copies are to be made is inserted
within the bag under the plate 6 through the open side of the bag the lips of which
are then brought together and the hooks are made to take hold of the studs or
eyes c¹ then a few strokes of the pump will exhaust air from the bag to form a
sufficient partial vacuum to give pressure to make the required copy or copies.
Air is then admitted into the bag by removing the hooks g at the ends of the bar f
or if desired by opening a small cock or valve provided for the
purpose.
Any other suitable construction of pump than that shown in figs. 1, 2 and 3 may
be used and the mode of securing the lips of the bag together may be varied.
The modification shown by figs. 4 and 5 is somewhat similar to that shown by
figs. 1 and 2.
The bag in this case is formed (as in the first modification described) by suitable
air tight elastic cloth or material united, air tight on all sides except that which is to
be the open side, to the lower lip of which a bar f is secured, which has a metal
clamp g attached at each end.

page_text: C
When the book (a) has been inserted in the bag the lips are brought together and
a bar c is placed on the outside of the upper lip, the ends of the bar c being inclined
to wedge under the inclined metal clip g. Any other mode of holding the closed lips
of the bag together may be used.
The pump in this modification may be attached to or separate from the bag, and if
separate may be connected by a pipe the junction for which is shown at d¹.
In the modification shown by fig. 6, two dishes h and i formed of any suitable
material are used instead of a bag, the upper dish h being flanged round its edge to
pass over the edge of the lower dish upon which a round ring j india rubber or
other elastic ring is placed, which is flattened somewhat when the upper dish h is
placed over it, this ring acting as a rolling packing ring to prevent the admission of
air to the interior between the dishes.
The book to be pressed is placed in the lower dish i, and the upper dish h is
placed over it, as shown in fig. 6, then the pump for exhausting the air is worked,
this pump communicating by a pipe with the lower dish i. A small flap or other
valve k is or may be used to allow air to enter when the book is to be removed.
This last described modification is well adapted for office purposes to be used in a
fixed position in which the lower dish i is or may be attached to a table. Where
exhausting pumps or other, exhausters are constantly working this press only requires
to communicate by a pipe with the pump or exhausted vessel so that the press may
thus be operated by turning a cock to open and close the communication between the
exhauster and the two dishes h and i.
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. The combination and arrangement of apparatus whereby pressure is obtained
for copying and other purposes by exhausting air therefrom substantially as
hereinbefore described and illustrated by the drawings.
2. The combination and arrangement of portable press substantially as hereinbefore
described and illustrated by figs. 1, 2 and 3.
3. The combinations and arrangements of presses substantially as and for the
purpose hereinbefore described and illustrated by figs. 4 and 5 and fig. 6 of the
drawings.
