do hereby declare the nature of this invention, and in what manuer the same is.
to, be performed, to be particularly described and ascertained. in and by the following
statement:-
:
My Invention relates to an improved machine.. for drying and ironing linen,
fabrics, paper, and other materials, and it consists in the combination, with 'the.
cylindrical ironing table clothed with a non-absorbent permeable covering, of anr-
exhaust current for carrying away vapor given off from the moistened fabric, as
hereinafter fully described.
is speciĔ-
Reference is to he had to the accompanying drawing, forming: part of this specifi- -
cation, in which figure.1 represents a longitudinal elevation of so much of the
machine as is necessary to explain the invention. Figure 2 is a section on line 12
figure 1. Figure 3 is a similar section of a modified arrangement. The same
letters of reference represent like parts in all three figures.
A is the ordinary concave steam-heated ironing bed and B the cylinder, which,
instead of being covered with swanskin as usual, is clothed with a thick.permeable
covering affording a ready passage for the vapor produced during the operation,
preferably constituted by a metallic or other brush surface or card clothing, as
specified in another application for Letters Patent of even date herewith. The
cylinder clothing, which is capable of being readily traversed by currents of air,
is preferably covered with one or two thicknesses of linen or other fabric. Imme
diately over the cylinder, for a portion of its circumference and throughout its
whole length, is applied a hood or casing C with the cavity bod of which a pipe T
is in communication, leading to an exhauster, which pipe may be provided with a
flexible coupling. The ends of the cavity bed are closed and the cavity is open
towards the circumference of the cylinder which is closely embraced by the parts a e
of the hood or casing. The position of the hood relatively to the vertical axis X, Y,
of the cylinder may be varied, but it is preferred to place it towards the outgoing
side S, the cylinder rotating in the direction indicated by the arrow f and the fabric
entering at E. The hood may be of copper or cast iron and it is supported in
position over the cylinder B in any suitable manner. It is preferable to provide the
cavity of the hood with a catch lip or to make said cavity of the special form shewn
in figure 3 for the purpose of collecting the water of condensation.
This figure
also shews the hood as supported by legs P jointed to it and to the receiving
table R.
The hood is independent of the ironing bed and may be applied to existing
machines; it never comes in contact with the fabric to be ironed and requires no
heating otherwise than by the hot air current traversing it. The lip e of the hood C
may be near enough to the point of delivery S to peel the fabric being ironed, etc.,
off from the cylinder.
The following is the action of the machine; the damp fabric entering the machine
at E is drawn between the cylinder B clothed in the manner described and the
corresponding concave face of the ironing bed A which is heated by steam or
otherwise and against which the fabric is pressed and finally passes out at point S.
During the traverse of the fabric from E to S, the vapor formed readily penetrates
the thin cover of the card clothing and enters the annular space comprised between
the outer covering and the fillet or foundation in which the dents are set whence
it is readily extracted by the exhaust towards which it flows through the annular
space and enters the cavity of the hood after again traversing that part of the outer
covering which is opposite the points bd in the reverse direction throughout the

page_text: whole length of the cylinder. As the vapor extracted is of a very high temperature
and mixed with hot air, it may be utilised on its way to the exhauster for heating
purposes, by passing it through a coil or otherwise before it is finally ejected into the
open air.
+
The improvements are applicable to all known kinds of ironing and finishing
machines, whether the ironing surface be above or below the cylinder and whether
made in one or several parts juxtaposed.
By means of the above described machine, combining as it does a porous clothing
and extractor worked by an exhaust fan, fabrics may be dried and ironed as they
come from the hydro-extractor, a very slight suction being sufficient and the power
required being only about one-tenth H.P.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In a drying and ironing machine, the combination, with a cylinder clothed with
a porous or vapor-collecting covering, of a hood or chamber in connection with an
exhauster and applied directly to the part not in contact with the ironing surface,
substantially as described.
2. In a drying and ironing machine, the combination, with a cylinder covered with
a brush or card clothing enclosed in an outer covering, of an exhaust hood or vapor-
collector and extractor independent of the ironing bed or surface, substantially as
herein before described and represented in the drawings, for the purpose specified.
