Improvements in Machinery or Apparatus for Drying Linen or other
Textile Fabrics.
J, EUGÈNE COINON, of Sens, in the Republic of France, Engineer, do hereby declare
the nature of this invention to be as follows
-
My invention relates to machinery or apparatus for drying linen or other textile
fabrics. It consists of a vertical shaft revolving in bearings, and set in revolution by
means of a pulley at its upper end Upon the shaft are fixed at a sufficient distance
apart two circular horizontal frames each having a number (preferably about twenty)
of radial angle iron arms extending from the centre to the external ng of the frame.
These angle irons serve as supports for moveable vertical frames of galvanized iron,
which keep the linen or other fabrics to be dried in a vertical position, the frames
being provided with horizontal bars to one side of which is attached a wire net or
trellis, against which the linen may be held by suitable fastenings.
The drying is very rapidly effected, first by means of a small coke oven or other
suitable apparatus in the bottom of the chamber in which the shaft revolves, such
heating apparatus being contained in a small chamber into which air is admitted
through a pipe from outside and after being heated is delivered through a second pipe
extending toward the centre of the apparatus whence it is projected outward by the
centrifugal force of the revolving frames. A pipe from the coke oven or other heating
apparatus also passes backward and forward in the lower part of the apparatus, and
communicates with a vertical pipe or chimney through which the hot products of
combustion are discharged, the interior of the apparatus being thus kept hot.
The rotation of the frames with the linen causes the hot air to penetrate the latter
and give rise to rapid evaporation, the saturated air passing away by the force of the
rotation through a discharge pipe provided with a regulating valve. A sheet iron
cover over the front of the coke oven communicates with a pipe through the chamber
to its upper part, air passing through it and being heated by the outer side of the
oven.
The outer chamber, in which the apparatus is contained may be of brickwork or
other suitable material, and it has in front a vertical door of sheet iron, through which
the vertical revolving frames can be introduced and withdrawn. A horizontal arm
may project out above the door and serve to support and guide the frames when being
so introduced or withdrawn, the latter being preferably provided with friction rollers
running upon the arm.
In order to prevent oil from the bearings from escaping into the apparatus, a cover
or case is provided fitting round them and having a pipe through which any surplus
oil runs and is discharged.
Any risk of burning is prevented by a metal grating upon the lower revolving
circular frame, which prevents any of the linen from accidentally falling to the bottom
of the chamber.
The apparatus requires little power, and may be driven by a gas engine or other
convenient power, or by hand.

Improvements in Machinery or Apparatus for Drying Linen or other
Textile Fabrics.
I, EUGÈNE COINON, of Sens, in the Republic of France, 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 and
accompanying drawing, (that is to say):-
My invention relates to machinery or apparatus for drying linen or other textile
fabrics or other materials.
In the accompanying drawing which is in illustration of my invention, figure 1 is a
vertical section, and figure 2 a horizontal section through the apparatus.
The apparatus consists of a vertical shaft A revolving in bearings, and set in
revolution by means of a pulley Pat its upper end. Upon the shaft are fixed at a
sufficient distance apart two cucular horizontal frames B, B, each having a number of
radial angle iron arms C extending from the centre to the external ring of the frame.
These angle irons serve as supports for moveable vertical frames N of galvanized iron,
which keep the linen or other fabrics to be dried in a vertical position, the frames
being provided with horizontal bars to one side of which is attached a wire net or
trellis, against which the linen may be held by suitable fastenings T.
The drying is very rapidly effected, first by means of the heat from a small coke
oven or other suitable apparatus D in the bottom of the chamber in which the shaft
revolves, the heat being utilized by means of pipes E.
The heating apparatus is contained in a small chamber F into which air is admitted
through a pipe H from outside and after being heated by circulating round the furnace
is delivered through a second pipe G extending toward the centre of the apparatus
whence it is projected outward by the centrifugal force of the revolving frames with a
force dependent upon the speed of rotation.
The pipe E from the coke oven or other heating apparatus also passes backward
and forward in the lower part of the apparatus, and communicates with a vertical pipe
or chimney, through which the hot products of combustion are discharged, the interior
of the apparatus being thus kept hot.
The rotation of the frames with the linen or other material causes the hot air to
penetrate the latter and give rise to rapid evaporation, the saturated air passing away
by the force of the rotation through a discharge pipe S contained in a case. K and
provided with a regulating valve. An outer sheet iron cover M over the front of the
coke oven communicates-with-a-pipe-R through-the-chamber-to-its upper-part,-air
passing through it and being heated by the outer side of the oven.
The outer chamber O in which the apparatus is contained may.be of. brickwork or
other suitable material, and it has in front a door of sheet iron, through which the
vertical revolving frames can be introduced and withdrawn. A horizontal arm, L may
project out above the door and serve to support and guide the frames when being so
introduced or withdrawn, the latter being preferably provided with friction rollers
running upon the arm.
In order to prevent oil from the bearings from escaping into the apparatus, a cover
or case X is provided fitting round them and, having a pipe Y through which any
surplus oil runs and is discharged into the lower bearing. Z
Any risk of burning is prevented by a metal grating upon the lower revolving
circular frame B, which prevents any of the linen from accidentally falling to the
bottom of the chamber.
The apparatus requires little power, and may be driven by a gas engine or other

page_text: 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. The combination of the outer chamber O, vertical shaft A, revolving frames B, B,
and moveable frames N, with the heating apparatus D, and pipes E, G, and H, sub-
stantially as and for the purposes described and shewn.
2. In combination with the chamber O and heating apparatus D, the cover M and
pipe R, substantially as described and shewn.
3 In combination with the revolving shaft A, the oil chamber X, and pipe Y,
substantially as described and shewn.
