PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Waterproof Garments and in
Apparatus therefor.
I, ISIDOR FRANKENBURG, of Greengate Rubber Works, Salford, in the County
of Lancaster, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to an improved method of forming the turn-overs or
hems and for forming the seam of rubber proofed garments and also in apparatus
adapted for the purpose.
It consists essentially in forming the hem or turn-over of a rubber proofed cloth
after it has been spread with a rubber solution by means of a turning appliance
and then pressing the turned over part by a pressure roller to cause the solu-
tioned edges to adhere and in apparatus constructed with a hemming or turning
over appliance in combination with a pressing roller and feed device without any
needle or thread carrying appliance.
In carrying out the invention the machine is constructed on the lines or after
the type of a sewing machine without any needle or thread apparatus motion
being transmitted to the feed apparatus. The presser is fitted with a pressing
roller and is held down by the action of a spring to give the desired pressure but
is capable of being lifted and held out of contact with the fabric.
The fabric is solutioned along the edge by a suitable machine or by hand and
the edge passed through a turning over or hemming appliance and then under
a pressing roller carried by a presser which compresses the two faces of the
solutioned edges and causes them to adhere.
Below the pressing roller is a feed for drawing the material through this may
either be reciprocating, serrated, or toothed bars or may be a roller or band feed.
The seams of proofed garments may be joined in a similar manner by being
passed or fed through the machine the top part of the seam being tightly pressed
upon the other by pressure roller.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Waterproof Garments and in..
Apparatus therefor.
I, ISIDOR FRANKENBURG, of Greengate Rubber Works, Salford, in the County
of Lancaster, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
This invention relates to an improved method of forming the turn overs or
hems and also the seams of rubber proofed garments and in mechanism adapted for
the purpose.
In consists essentially in forming the hem or turnover of a rubber proofed cloth

RCTIC WHO any
The invention will be fully described with reference to the accompanying
drawings
Fig. 1. Side elevation partly in section.
Fig. 2. Front elevation partly in section.
Fig. 3. Plan of- bed plate.
Fig. 4. Sectional plan of pressing roller.
The apparatus is constructed with a frame A similar to that of a sewing
machine o of any other convenient shape and with a serrated feed 'bar Bor other
feed motion commonly known or used with a sewing machine for carrying the
work through.
Above the feed apparatus is placed a pressing roller C carried by a vertical
spindle D and held down upon the work with a considerable amount of pressure
by the spiral spring E or by other suitable spring bearing upon the spindle D.
The tension of the spring and the pressure extended by the pressing roller C
upon the work is adjusted by the screw F. The pressing roller is lifted from off
the work when not required by the eccentric lever G.
The pressing roller is mounted on a spindle c carried by the bracket H which
is pivoted to a second bracket K fitted to the end of the spindle D. The pivots b
permit of the roller C being removed clear of the work into the position shown in
broken lines in Fig. 1.
It is held in normal position by the spring h.
To the bed of the apparatus is attached a turning over or hemming appliance L
which is made of sheet metal with the edge curled or bent over to the shape shown
in Figs. 1 & 3, and is secured by the screw 7.
The fabric is "solutioned" or coated along its edge with a rubber solution either
by machine or by hand and the edge with the solution upon it is passed through
the turning
over or hemming appliance L and then under the pressing roller C
being carried forward by the feed motion B. The pressure applied by the press-
ing roller C compresses the two faces of the "solutioned" edges and causes them
to adhere.
The seams of proofed fabrics or garments may be joined in a similar manner
by being fed through the machine under the pressing roller C the top part or ply
of the seam being tightly pressed upon the other and thereby caused to adhere
thereto.
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:-
1. The method of forming the hems and seams of rubber proofed fabrics or
garments by applying the solution thereto by machine or hand and then passing
through a machine (in the case of hems after being turned) and tightly com-
pressing the solutioned surfaces by a pressing roller substantially as described.
2. The apparatus for forming the hems and seams of rubber proofed fabrics or
garments constructed and arranged substantially as described and shown.
