IMPROVEMENTS. IN AND MACHINERY FOR THE MANUFACTURE OF WATERPROOF CLOTH
Year: 1884

page_text: I ELLIS SOLOMON. HELWITZ of 46 Robert Street Cheetham near Manchester in
the County of Lancaster Waterproof garment Manufacturer do hereby declare the
nature of my invention for IMPROVEMENTS. IN AND MACHINERY FOR THE
MANUFACTURE OF WATERPROOF CLOTH to be as follows:-
The object of this invention is the construction of a machine whereby the coating
of the cloth with india-rubber material can be effected in one and the same Machine
and the cloth be completely finished and ready for the Market, instead of subjecting
the same to treatment in several different Machines as hitherto practised and
whereby a considerable saving of time is effected.
In carrying out my invention I mount a series of rollers in a stationary frame
and between the two upper rollers which are separated a sufficient distance I mount
a diagonal knife or blade to press upon the material passing over the rollers, And
in front of this stationary frame I arrange a travelling frame containing a roller and
which can be affixed at any distance required from the fixed frame.
Over the rollers in these two frames I pass the material and then by connecting
their ends together underneath so form an endless band.
The india-rubber solution or coating material is then introduced in front of the
diagonal knife or blade and the rollers set in motion when the cloth is gradually
drawn beneath the knife or blade and so becomes coated as it passes along.
'
And in order to Vulcanise the cloth I arrange a trough in which revolves a roller
which by taking up the vulcanising liquid so imparts the same to the surface of the
cloth, and which cloth is also polished by a similar roller and trough conveniently
disposed for the purpose.
In this manner
:
am enabled to cover with any desired number of coats and to
vulcanise and finish waterproof cloth without removing the same from the Machine.
. These improvements are specially applicable in producing what are known as
transparent and electric Waterproof cloths.

page_text: I ELLIS SOLOMON HELWITZ of 46 Robert Street, Cheetham near Manchester in the
County of Lancaster Waterproof Garment Manufacturer, do hereby declare the
nature of my invention of "IMPROVEMENTS IN AND MACHINERY FOR THE MANU-
FACTURE OF WATERPROOF CLOTH," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
The object of this invention is the construction of a machine, whereby the coating
of the cloth with india-rubber material can be effected in óne and the same machine
and the cloth be completely finished and ready for the market instead of subjecting
the same to treatment in several different machines as hitherto practised and
whereby a considerable saving of time is effected.
On the accompanying drawing Fig 1 represents a side sectional view and Fig 2 a
plan of a waterproofing machine constructed in accordance with my invention both
views being shewn broken in the centre for want of space to illustrate the machine
in its entirety,
In carrying out my invention I mount a series of rollers a, b, c in a stationary
frame d and between the two upper rollers a and b which are separated a sufficient
distance I mount a diagonal knife or blade e to press upon the material passing over
the rollers and so make a trough for the reception of the waterproof compound f.
And in front of this stationary. frame I arrange a travelling frame g containing a
roller h and which can be adjusted at any distance required from the fixed frame
by the windlass i actuated by the worm and worm wheel k. Over the rollers in
these two frames I pass the material and then by connecting their ends together
underneath I so form an endless band.
The action of this improved machine may be described as follows The india,
rubber solution or coating material having been introduced as aforesaid into the
trough formed by the pressure of the diagonal knife or blade and the rollers set in
motion by hand or by a strap passing round the fast and loose pulleys a the endless
band of cloth is gradually drawn in the direction of the arrows beneath the knife
or blade é and so becomes coated as it passes round the rollers. If it be now
required to impart. an additional coating to the fabric I prefer to run it in the
contrary direction to the arrows after previously removing the knife or blade e, and
inserting it in the diagonal groove e, and applying the further coating solution in
the trough formed in front of the blade as aforesaid.
And in order to vulcanise the cloth so coated I suspend a trough m by means of
a pair of ropes or chains n over the pulleys o and cause the same to-be raised by.
winding the other end of the said ropes or chains upon the roller p. In this trough
I mount the ordinary vulcanising roller q which as it revolves by taking up the
vulcanising liquid out of the trough so imparts the same to the surface of the cloth.
The polishing of the cloth is effected by. a similar roller and trough conveniently
disposed for the purpose or suspended from the same pulleys o as the vulcanising
trough which in this case is first.removed.
In accordance with this invention and by arranging the cloth or fabric to be
coated in an endless band form as aforesaid greater facility is afforded than hereto-
fore for drying the cloth and hence I am enabled to cover with any desired number
of coats and to vulcanise and finish waterproof cloth without removing the same
from the machine-These improvements are specially applicable in producing what
are now known as transparent and electric waterproof cloths.

page_text: Having thus particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1st The improved method of waterproofing fabrics substantially as and for the
purposes herein before described.
2nd The general construction and arrangements of waterproofing machinery
whereby the fabric is coated with one or more coats and is vulcanised and polished
all in one and the same machine substantially as hereinbefore described and illus-
trated on the accompanying drawing.
