I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of 53,.
Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents,
do hereby declare the nature of this Invention to be as follows:-
This Invention relates to the manufacture of water-proof arm-pit linings, known as
dress-protectors, and the Invention consists in the manufacture of such water-proof
dress protectors without seams or joins at the curved part by means of machinery
specially designed for the purpose as hereafter described.
The water-proof fabrics are coated with caoutchouc in the usual way and may be
either single or double texture fabrics, that is to say the caoutchouc may be applied
on one surface of a fabric or between two thicknesses of fabric as well known.
In either case the indiarubber coated fabrics are cut up in strips following exactly
the warp of the fabric, the strips being then superposed to the number of, say, 48 and
the pile stamped or cut out of a truncated oval form and of an area equal to the
material necessary for the development of the crescent of the dress-protector..
The vulcanization of indiarubber-coated white or coloured surfaces, is effected a few
moments prior to its forination and the vulcanization of double texture or pure rubber
coated fabrics is effected after formation. In either case a light bath of sulphide of
carbon and chloride of sulphur is used.
Reference is to be had to the accompanying drawings forming part of this specifica-
tion and illustrating an example of the machinery for pressing into shape the improved
articles in question.

to a proper temperature according to the fabric to be operated on, The pieces of
fabric cut out to a truncated oval shape suited to form a dress-protector when pressed
up as hereafter described, one, two, or more pieces (according to thickness) are laid
upon the cylindrical surface of the heated tabled between the guides p fixed adjustably
thereon.
An envelope is then applied to the two faces of the upper knife t in order to permit
the india-rubber coated fabric to be forced down between the boxes d in a regular
manner and without wrinkling. The knife t being then brought down by turning
wheel m, the fabric is doubled and forced down between the boxes and pressed
between the curved edges of the upper and lower knives or dies and into the groove
of the lower knife. The descent being effected, the lower knife is retained by the
pawl . The material is kept under pressure for a minute or so, after which the paw!
is released and the movable box d moved outwards by the cam leverf, the pressed
article being thereupon raised above the table by the springs B, and lower knife s.
To prevent adhesion of the fabric the caoutchouc is dusted over with powdered talc,
soap, or flowers of sulphur.

or Dress Protectors and in Machinery. therefor.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents,
do hereby declare the nature or this Invention (a communication to me from abroad
by La Société A. Hutchinson et Compagnie of 1 Rue d'Hauteville Paris in the
Republic of France, India rubber Manufacturers) 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 manufacture of water proof arm pit linings known as
"dress protectors"; and the Invention consists in the manufacture of such water
proof dress protectors without seams or joins at the curved part, by pressing the
fabric to the desired form by means of machinery specially designed for the purpose,
as hereafter described.
The water proof fabrics to be pressed by the machinery herein described, are fabrics
coated with caoutchouc in the usual way and may be either single or double texture
fabrics, that is to say, the caoutchouc may be applied on one surface of a fabric or
between two thicknesses of fabric as well known. In either case, the India-rubber
coated fabrics are cut up in strips following exactly the warp of the fabric, the strips
being then superposed to the number of, say 48, and the pile stamped or cut out of a
truncated oval form and of an area equal to the material necessary for the development
of the crescent of the dress-protector. The vulcanization of India rubber coated white
or colored surfaces, is effected a few moments prior to its formation, and the
vulcanization of double texture or pure rubber coated fabrics, is effected after forma-
tion. In either case, a light bath of sulphide of carbon and chloride of sulphur-is
used.
Reference is to be had to the accompanying drawings forming part of this
Specification and illustrating an example of the machinery for pressing into shape the
improved articles in question. Figures 1 and represent an end elevation and plan
of the improved machine. Figures 3 and 4 represent vertical and horizontal sections
of the machine. Figure 5 shews a side clevation of the machine. Figure 6 is a detail
in section on line 1-2 figure 5, and figure 7 is an elevation of the same. Figure 8 is
a detail of the mechanism.
?'
a is the base plate, whereon are fixed the columns b by set screw c. dd is a curved
table formed of two heated boxes A B, the one A being fixed to the bed plate, the other
B being fitted to work on the bed plate in slides and moved from or to the fixed die
by means of curved slotted cams f keyed on shaft engaging with pins i and worked
by lever f. The shaft is carried by straps e fixed adjustably in guides on the fixed
box A, the adjustment being effected by screws and the straps fixed by set screws.
The adjacent ends of the boxes A B are faced with movable plates j held to the two
boxes by vertical guides.
The boxes A B are heated by steam pipes carried on brackets k. Between the
faces of the boxes is fitted to slide a lower knife or die s of the curved form shewn in
half elevation in Figure 6, this die being a flat plate with a grooved curved upper edge

page_text: and furnished at the lower sides with hooked arms D working in guide slots in the
columns and attached to spiral springs D' therein, by which the lower knife or die
is raised at the proper moment, as hereafter described, this die or knife being held
down by a pawl land a rock shaft e¹ worked by a lever . The knife or dies is made
of steel and has an opening at the middle of its flat part to prevent warping by heat.
The upper ends of the springs D¹ are attached to pins q.
wheel m.
The upper die or knife t has its lower edge curved to correspond to the lower knife
or die. It is fitted to slide in guides y on the columns and is attached to a rack u
gearing with a pinion on a shaft mounted in the bridge to and worked by hand
The top knife t is held in the raised position by a counter balance weight
acting through a cord running over pulleys no. The top knife or die works between
the faces of the boxes A B, and comes down upon the lower die or knife, pressing
are screw-bolts for fixing bridge w to columns b.
The method of manufacture is as follows;-The machine being closed and heated to
a proper temperature, according to the fabric to be operated on The pieces of fabric
cut out to a truncated oval shape suited to form a dress protector, when pressed up as
hereafter described, one two or more pieces (according to thickness) are laid upon the
cylindrical surface of the heated table between the guides p fixed adjustably
the material between them.
An envelope is then applied to the two faces of the upper knife t in order to permit
the India rubber coated fabric to be forced down between the boxes d in a regular
manner and without wrinkling. The knife t being then brought down by turning.
wheel m, the fabric is doubled and forced down between the boxes and pressed between
the curved edges of the upper and lower knives or dies and into the groove of the
lower knife. The descent being effected, the lower knife is retained by the pawl l.
The material is kept under pressure for a minute or so, after which the pawl is released,
and the movable box d moved outwards by the cam lever f, the pressed article being
thereupon raised above the table by the springs D and lower knife s.
To prevent
adhesion of the, fabric the caoutchouc is dusted over with powered tale, soap, or flowers
of sulphur.
Having now particularly described and ascertained the nature of the said Invention,
and in what manner the same is to be performed, I declare that what I claim is ;-
1st. The manufacture of water proof arm-hole linings or dress protectors without
seams or joins by the aid of heat and pressure, as described.
