We WILLIAM EDWARD CARRINGTON of the firm of S. R. Carrington and Sons
of Cale Green Works Stockport in the County of Chester, Hat Manufacturer, and
RICHARD TIPPING of Heavily Stockport aforesaid Mechanic do hereby declare
the nature of our invention for "IMPROVEMENTS IN APPARATUS EMPLOYED FOR'
PRESSING HATS to be as follows:-
"ን
This invention relates to the construction of apparatus to be used in place of the
cast iron "pots" usually employed in combination with elastic hydraulic or air
bags" for pressing hats by hydraulic or atmospheric pressure. In the ordinary
process a separate "pot" is required for each separate form and size of hat to be
pressed, and as these pots are of considerable thickness and very heavy a great
deal of unnecessary labour in moving and changing these "pots" is entailed upon
the workmen.
:
According to this invention we employ a heavy cast iron hollow vessel or
receptacle of a much larger capacity than the ordinary "pot" and inside this vessel
fit a light mould or shell made of cast or sheet brass steel or other suitable metal
or alloy, and of the size and form of the. hat required to be pressed, a separate-
mould or shell only being required for each size or shape of hat.
This light mould or shell is made with a flange by means of which it is secured
to the top or rim of the cast iron vessel or receptacle above named thus leaving a
space all round between the outer surface of the shell and the inner surface of the
cast iron vessel and the upper part of which space is closed in by means of the said
flange, the joint being made close by means of a washer or ring of india rubber or
other equivalent.
The space thus formed is to be filled with water air or other fluid (compressed or
otherwise) or it may be packed with sand or other equivalent so as to form a more
or less solid bearing or bed for the outside of the light mould or shell, and support
the same against the internal pressure of the elastic hydraulic or air "bag" when
pressing hats by hydraulic or air pressure.
The pipes conveying the water air or other fluid into the space above named
may be connected directly to the pump or other source of supply, or they can be
connected to the pipes which convey the water or compressed air to the elastic
bag" employed for giving the pressure so as to ensure uniformity of pressure
both inside and outside the light mould or shell aforesaid.
It will be evident that the same cast iron vessel or receptacle can be used for any
size or shape of hats and that it is only the light mould or shell that will require to
be changed and thus the labor of the workmen will be considerably reduced.

page_text: We WILLIAM EDWARD CARRINGTON of the firm of S. R. Carrington and Sons
of Cale Green Works Stockport in the County of Chester Hat Manufacturer, and
RICHARD TIPPING of Heavily, Stockport aforesaid Mechanic do hereby declare the
nature of our invention for IMPROVEMENTS IN APPARATUS EMPLOYED FOR PRESSING
HATS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to the construction of apparatus to be used in place of the
cumbersome cast iron " 'pots" usually employed in combination with elastic
hydraulic or air "bags" for "pressing" hats by hydraulic or atmospheric pressure.
In the ordinary process a separate "pot" is required for each separate form and
size of hat to be pressed and as these "pots" are of a considerable thickness and
very heavy a great deal of unnecessary labor in moving and changing them is
entailed upon the workman.
This invention is designed to obviate the above inconvenience and to reduce
considerably the labor of the workmen.
The nature and object of our said invention will be readily understood on
reference to the annexed sheet of drawings, which are marked with figures and
letters of reference corresponding with those in the following explanation thereof.
Fig. 1 on the annexed drawing is a vertical section of our improved apparatus,
and Fig. 2 is an underneath sectional plan view of the same.
According to this invention we employ only one heavy cast iron hollow vessel or
receptacle a, a of a much larger capacity than the ordinary "pot" above which we
prefer to place a movable ring b, b into which fits a light mould or shell c, c made
of cast or sheet brass, steel, or other suitable metal or alloy, and of the size and form
of the hat required to be pressed.
This light mould or shell c, c is made with a flange resting on the ring b, b
which latter is secured to the top or rim of the cast iron vessel or receptacle a, a
above named, thus leaving a space d, d all round between the outer surface of the
cast iron vessel a, a, the upper part of which space is closed in by means of the
said ring b, b the joint being made close by means of a washer or ring e, e of india
rubber or other equivalent.
The space d, d thus formed is to be filled with water, air, or other fluid (com-
pressed or otherwise); in the drawing it is shown as filled with water admitted by
the forked pipe ff or it may be packed with sand or other equivalent so as to form
a more or less solid bearing or bed for the outside of the light mould or shell c, c
and support the same against the internal pressure of the elastic, hydraulic or "air"
bag when pressing hats by hydraulic or atmospheric pressure.
The pipes f. f for conveying the water, air, or other fluid into the space d d may
be connected directly to the pump or other source of supply or they can be
connected to the pipes which convey the water or compressed air to the elastic
"bag" employed for giving the pressure, so as to ensure uniformity of pressure
both inside and outside the light mould or shell c, c. It will be evident that the
same cast iron vessel or receptacle a, a can be used for any size or shape of hats

page_text: and that it is only the light mould or shell c, c and the ring b, b that will require
to be changed and thus the labor of the workman will be considerably reduced:
g is an opening for withdrawing the water, and h, h is a passage for the escape of
the air; both of these should be fitted with a tap or valve.
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
In apparatus for "pressing" hats the combination with a single cast iron
receptacle or reservoir of a number of light movable moulds or shells of different
sizes and forms so as to leave a space between the two for the reception of water
compressed air or other fluid or equivalent to support the light mould or shell under
pressure substantially in the manner and for the purposes hereinbefore set forth,
described, and illustrated by the drawing annexed.
