Improvements in or relating to Ironing Machines, Ironing Boards,
and Calendering Machines.
I, JOHN GAMGEE of 6 Lingfield Road, Wimbledon in the County of Surrey,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention has reference to ironing machines and ironing boards and also to
calendering machines, and so far as it relates to ironing machines and calendering
machines it consists in the first place in the combination of a revolving roller and a
concave bed or trough, between which the goods or material to be ironed or calendered
are passed, the roller and the bed being both heated by superheated water, made to
circulate through cores or passages made in the metal of which the roller and bed
are formed. The water may be circulated by means of a pump or otherwise and
when a pump
employed for the purpose it may be a small pump fixed to or near
the machine, or it may be a larger sized pump used for other purposes in the
laundry or building, the water being conveyed therefrom to the roller and bed by a
pipe.
The invention further consists in perforating the circumference of the roller for
the greater part of its length between the circulating cores with small holes and in
fitting within the roller a pipe in connection with a vacuum chamber or exhaust
apparatus which carries off through the hollow bearing or journal of the roller the
moisture or condensed steam which is generated from the goods and passes into the
roller through the small holes.
The invention further consists in fitting the bed in vertical slides or otherwise so
that it can be lowered vertically when required in order that it may be cleaned or
the flannel covering or ironing cloth thereon adjusted. The bed or the roller is also
made self adjusting by means of levers and weights so as to adopt the machine to
different textures or thicknesses of material.
'
The invention further consists in combining with the heated roller and bed a pair
of auxiliary rollers of polished steel or other suitable material made to revolve by
gearing in connection with the main roller. The goods after passing between the main
roller and bed pass between these auxiliary rollers which give them a final polish or
gloss.
In order to prevent the main roller taking the material to the bed before the person
in charge has it in proper position or free from creases a feed board is provided "which"
does not feed the material until tipped or inclined by a controlling treadle.
As regards ironing boards, I make them hollow, form them with a number of small
holes at top for nearly their whole length and connect the inside of the board with
a vacuum chamber or exhaust apparatus for carrying off the moisture as herein before
described with reference to the ironing or calendering roller.

Improvements in or relating to Ironing Machines, Ironing Boards,
and Calendering Machines.
I, JOHN GAMGEE of 6 Lingfield Road, Wimbledon in the County of Surrey,
Gentleman, 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 has reference to ironing machines and ironing boards and also to

page_text: calendering machines, and so far as it relates to ironing machines and calendering
machines it consists in the first place in the combination of a revolving roller and
a concave bed or trough between which the goods or material to be ironed or
calendered are passed, the roller and the bed being both heated by superheated or hot
water, or steam and water mixed made to circulate through cores or passages made
in the metal of which the roller and bed are formed. The water or steam and
water may be circulated by means of a pump or otherwise and when a pump is
employed for the purpose it may be a small pump fixed to or near the machine, or
it may be a larger sized pump used for other purposes in the laundry or building, the
water being conveyed therefrom to the roller and bed by a pipe.
The invention further consists in perforating the circumference of the roller for the
greater part of its length between the circulating cores with small holes and in fitting
within the roller a pipe in connection with a vacuum chamber or exhaust apparatus
which carries off through the hollow bearing or journal of the roller the moisture or
condensed steam which is generated from or given off by the goods and passes into
the roller through the small holes.
The invention further consists in fitting the bed in vertical slides or otherwise so
that it can be lowered vertically when required in order that it may be cleaned or the
flannel covering or ironing cloth on the roller adjusted. The bed or the roller is also
made self adjusting by means of levers and weights so as to adapt the machine to different
textures or thicknesses of material.
The invention further consists in combining with the. heated roller and bed a pair
of auxiliary rollers of polished steel or other suitable material made to revolve by
gearing in connection with the main roller. The goods, after passing between the
main roller and bed, pass between these auxiliary roilers which give them a final polish
`or gloss.
In order to prevent the main roller taking the material to the bed before the person
in charge has it in proper position or free from creases, a feed board is provided
which does not feed the material until tipped or inclined by a controlling treadle.

The accompanying drawings represent an ironing machine in which my improve-
ments are embodied. Figure 1 is a sectional elevation, Figure 2 a cross section on
the line A B of Figure 1 and Figure 3 a plan. The feed and delivery tables and the
auxiliary rollers are shown in Figure 3 only. e is the ironing roller; it is made of
cast iron or other metal and revolves in bearings carried by the standards f g is the
concave bed or trough between which and the roller e the goods to be ironed are
passed. In the metal of which the roller e is formed longitudinal cores or passages e¹
are made; these cores or passages communicate with each other by passages in the
covers or ends of the roller in the manner shown at e Figure 2 so that there is a
continuous passage or way backwards and forwards through the cores e¹ and
passages e commencing at the hollow journal p and terminating at the hollow journal q.
The superheated or hot water or mixed steam and water for heating the roller is
caused to circulate through the cores or passages by means of a pump or otherwise
entering by the journal p and leaving at the journal g. The journal 9 has an inner
sleeve which remains stationary while the roller e revolves and in this sleeve are
two passages r and s, r being for the outlet of the hot water or mixed steam and water
as above described, and s being in communication with a vacuum chamber for the
purpose hereinafter explained. The bed or trough g is similarly formed with com-
municating cores or passages w through which superheated or hot water or mixed
water and steam is caused to circulate, the inlets being by the pipes u u and the outlet
by the pipe v. The circumference of the roller e is perforated as indicated at c²
(in Figures 1 and 2) for the greater part of its length with small holes and the
roller has fitted within it a pipe t forming a continuation of the passage s already
referred to. This passages is in connection with a vacuum chamber or exhaust
apparatus which draws off the moisture or condensed steam which is generated from
or given off by the goods and passes into the interior of the roller e through the
small holes c².
The bed g is fitted in vertical slides g¹ so that it can be lowered when required in

page_text: order that it may be cleaned or the flannel or cloth on the roller e adjusted. The
bed g is also made self adjusting so as to adapt itself to different textures or thicknesses
of material by means of levers i and weights j. The lowering is effected by means
of a screw k working in a nut / on the distance piece m and operated by a hand wheel
sufficient clearance being allowed in the recess o for the self adjustment for different
textures or thicknesses of material as just referred to.
xx are the auxiliary rollers made to revolve by gearing in connection with the
roller e and at the same surface speed. The goods after passing between the
roller e and bed 9 pass or are lifted to the rollers a which give them a final polish or
gloss.
which
The goods are fed to the machine at a (Figure 2) and in order that the roller e
may not take hold of them until in proper position or free from creases a feed
board b is provided which is controlled by the weighted treadle e through the rods c¹.
When the treadle is pressed down the board b is moved away from the roller
does not, therefore, take hold of the goods; but when the pressure is removed the
weights d cause the board 6 to move forward against the roller. y is a table on which
the goods may be laid prior to being introduced into the machine and z is a delivery
or folding table.
The machine can be driven by any suitable power.
A calendering machine constructed according to my invention will be the same
as the ironing machine already described with such obvious changes in the details as
are necessary.
As regards ironing boards I make them hollow, form them with a number of small
holes at top for nearly their whole length and connect the inside of the board with a
vacuum chamber or exhaust apparatus for carrying off the moisture as hereinbefore
described with reference to the ironing or calendering roller.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In an ironing or calendering machine, the combination of a roller and a concave
bed or trough each of which has in the metal of which it is made a number of cores
or passages communicating with each other so as to form a continuous passage for
the circulation of superheated or hot water or mixed steam and water under the
influence of a pump or other forcing device substantially as hereinbefore described.
2. In an ironing or calendering machine, the combination of an ironing or
calendering roller having hot water circulating passages for heating same and
perforations in its periphery for the passage into the interior of the roller of moisture
or condensed steam from the goods under treatment, and of a vacuum chamber or
exhaust apparatus for drawing off such moisture or condensed steam substantially as
hereinbefore described.
3. In an ironing or calendering machine, the combination with an ironing or
calendering roller and with a concave bed or trough such as are herein set forth of
a pair of auxiliary rollers between which the goods are passed after having passed
between the main roller and the bed or trough, substantially as hereinbefore
described.
4. The combination of parts substantially as hereinbefore described constituting an
improved ironing or calendering machine.
5. A hollow ironing board baving a number of holes at top for the passage into the
interior of moisture or condensed steam from the goods that are being ironed, the
said hollow board being connected with a vacuum chamber or exhaust apparatus for
drawing off such moisture or condensed steam, substantially as hereinbefore
described.
