page_text: I, ALBERT LAY, of Old Bedford Road, Luton, in the County of Bedfordshire,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved hydraulic hat press, which consists of an
apparatus fitted to an ordinary press for pressing the crown of hats of various
manufacture by hydraulic pressure.
In carrying my invention into practice, I construct a pan of any suitable shape
and place the said pan in the bed of an ordinary pressing machine. The aforesaid
pan is heated by gas or steam through suitable pipes and fittings. Another part
of my invention is to construct an oval wood or metal block (hollow or otherwise)
of such a shape at its base so as to fit partly inside or on the edge of the inside of
a hat crown with a flat surface on the top. To the top of the aforesaid block
I fix a piece of bent tube having its connection at the back of the apparatus,
also a water way is cut through the above described block. Around the base and
a part of the aforesaid block, I place a strong india rubber bag, the edges of which
are turned over on the top of the said block, and above the said edges of the india
rubber bag I place a flat oval metallic ring with an additional flat metal or wood
block which I rigidly fix together by means of screws or bolts; the said apparatus
is connected to the horizontal plate attached to the bottom of the vertical screw
of the ordinary press for pressing the apparatus into or on the crown of the hat
that is placed in the heated pan. To the bent tube fixed in the oval metal or
wood block I connect by means of valves, ties, bends, pipes and flexible tubes
the water with a proper inlet and outlet, in order to operate the apparatus by
hydraulic pressure or by a hydraulic pump. The water may be laid on from
the main pipe and the outlet formed in any convenient way that may be found
suitable according to the position of water pipe in any factory.
The object of my invention is to provide the above described apparatus which
may be fitted to any existing hat press for the due performance of the work herein-
before described.

page_text: the same is to be performed to be particularly described and ascertained in and by
the following statement:-
-
My invention relates to an improved hydraulic hat press, which consists of an
apparatus fitted to an ordinary press for pressing the crown of hats of various
manufacture by hydraulic pressure.
And in order that my invention may be thoroughly understood, I now pro-
ceed to describe the accompanying drawing .thereof, reference being had to
letters and figures marked thereon.
Fig. 1, is a front elevation of the press.
Fig. 2, is a side elevation.
Fig. 3, is a plan of the top of the bed or sliding table.
Fig. 4, is an alternate construction for the sliding bars, with the legs fixed
at each angle.
Fig. 5, is an enlarged plan of the top of the india rubber bag.
Fig. 6, is a section on line A, B, drawn to an enlarged scale.
Fig. 7, is a back elevation of Fig. 6.
In carrying my invention into practice, I construct a pan of any suitable shape.
and place the said pan c in the bed 6 of an ordinary pressing machine. The bed b
is mounted on sliding bars a for the purpose of allowing the bed to slide in or
out. The aforesaid pan c is heated by gas or steam through suitable pipes a and
fittings. Another part of my invention is to construct an oval wood or metal
block e (hollow or otherwise) of such a shape at its base so as to fit to an oval
flat iron plate e¹ as in Figs. 6, and 7. To the top of the aforesaid plate e¹ I cut
a groove for the purpose of placing the connector, and on this connector e I fix
a piece of bent flexible tube f having its connection at the back of the apparatus,
also a water way g is cut through the above described block e and block e for
receiving the vertical and horizontal tubes and elbow. I place a strong india
rubber bag h, the edges or flanges of which are turned over on the top of a wood
block, and above the said edges of the india rubber bag h I place a flat oval
metallic plate e¹ grooved at the back for the water way which I rigidly fix together
by means of a number of screws e³ or bolts; the said apparatus is connected to the
horizontal plate or sliding bar i attached to the bottom of the vertical screw j of
the ordinary press for pressing the apparatus into or on the crown of the hat that
is placed in the heated pan c. To the flexible tube f fixed in the oval wood or
metal block e I connect by means of valves, tees, bends, pipes and flexible tubes,
the water with a proper inlet and outlet, in order to operate the apparatus by
hydraulic pressure or by a hydraulic pump. The water may be laid on from the
main pipe and the outlet formed in any convenient way that may be found suitable
according to the position of water pipe in any factory.
The ends of the horizontal bar i attached to the vertical screw j works in vertical
grooves & cut in the inside of the vertical arms 7 of the press.
At the top of the vertical screw j I fix a hand wheel m for operating the apparatus.
The apparatus is mounted on suitable legs.
A gauge n is fitted to the water pipe for the purpose of testing the pressure
of water in the india rubber bag.
A water waste cistern o is placed at the base for the purpose of receiving the
exhaust steam from the pan c.
I do not particularly bind myself to make the india rubber bag h block e and
the plate e¹ of the exact shape shewn in the drawing, as I might vary the shape
of same without departing from the nature of my invention.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a hydraulic hat press, the combination of the pressing block e² and the
india rubber bag h, substantially as herein described and according to the accom-
panying drawing.

page_text: 2. In a hydraulic hat press, the apparatus fitted to an ordinary press for pressing
the crown of hats of various manufacture by hydraulic pressure, substantially
as described.
3. In a hydraulic hat press, the combination of the oval block e plate e¹ block e
and india rubber bag h, substantially as described and according to the accom-
panying drawing.
