We, ALEXANDER CUNNINGHAM, of 96 Curtain Road in the County of Middlesex
India Rubber manufacturer and JOHN WILLIAM POSTLETHWAITE of 3 Gracechurch
Street in the City of London India Rubber manufacturer do hereby declare our said
invention to be as follows :-
:-
This invention consists in improvements in spreading and doubling macintosh
waterproof cloth.
According to our invention we take a piece of fabric and coat it with india rubber
solution or other adhesive waterproof substance similar to other well known macintosh
waterproof cloths but when coated by our improved machinery hereafter described the
cloth is much lighter and more free from pin holes than heretofore. The machinery
for coating the fabric with waterproof material we construct and arrange substantially
as follows:-On a suitable rectangular framing we mount horizontally three rolls
extending the whole width of the machine, the centre roll being mounted so that it.
may be raised or lowered as hereafter described and one of the other rolls which I
call the back roll is also adjustable horizontally, over this last named roll and the
centre one we pass an endless rubber band or bands or blanket to form a good
support for the fabric to be coated the bands or blanket may be tightened more or
less by the screws of the back roll aforesaid. On the axle of the centre roll at each
end we mount loosely an arm to the ends of which we pivot a diamond shaped knife
or guage with two edges carrying ears in the ordinary way, this knife extends the
whole width of the endless blanket In order to coat a piece of fabric with waterproof
material we proceed as follows:-
We cement the two ends of the piece of fabric to be coated so as to form an endless
band this band being passed over the aforesaid back roll and also over a roll fixed in
a portable frame placed at a suitable distance according to the length of the band to
be coated. We then turn the knife or gauge so as to rest on the cloth we then by
any suitable means apply the waterproof solution or dough. The rolls are then put
into motion by suitable means when the waterproof material will be spread thinly and
מ.

page_text: evenly this we continue until the desired thickness of coating is obtained according to
the purpose for which the fabric is required and by this machinery the cloth may be
also surfaced, polished or chalked.
In order to form cloth known as double texture we first take a piece of cloth which
may form the lining coated as aforesaid and roll it on a roller placed above or at any
other suitable part of the machine. We then form and coat another piece of fabric in
the same way as that last described and when the last coat is being put on we bring
one end of the previously coated cloth under another roll similar to and fixed over the
back roll and coming on to the endless blanket aforesaid and upon starting the machine
the two cloths during their passage over the back roll will be pressed together and the
two waterproof surfaces coming in contact will cause them to adhere. We would
remark that the roll under which the former piece of coated material passes is
adjustable so that it is only lowered when the last coating is put on (or during this
operation) the second piece of fabric as aforesaid.
To each end of the axles of the back roll and doubling roll last referred to, we
mount, loosely, suitable pulley wheels so as to pass india rubber bands to accumulate
the pressure between same as required. Fabric treated as above when taken from the
machinery is vulcanized or otherwise treated in the usual way.
Further according to this invention we cover the machinery with wire gauze so
that in case of fire it may not be cominunicated to the 'building in which the machinery
is placed.

We ALEXANDER CUNNINGHAM of 96 Curtain Road in the County of Middlesex
India Rubber manufacturer and JOHN WILLIAM POSTLETHWAITE of 3 Gracechurch
Street in the City of London India Rubber manufacturer, do hereby declare our said
invention and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
This invention consists in improvements in spreading and doubling macintosh
waterproof cloth.
According to our invention we take a piece of fabric and coat it with india rubber
solution or other adhesive waterproof substance similar to other well known macintosh
waterproof cloths but when coated by our improved machinery hereafter described the
cloth is much lighter and more free from pin holes than heretofore. The machinery
for coating the fabric with waterproof material we construct and arrange substantially
as follows:-
And in order to explain our said invention more fully we will now proceed to
describe the same with reference to the accompanying drawings in which figure 1
shews end elevation of machine. ready for doubling cloth together. Figure 2 front
elevation of doubling machine. In each of the above views the same letters denote
the same parts. a is the framing on which is mounted two rolls b. c. the roll 6 being
adjustable so that it may be raised and lowered or moved horizontally. Over the
rolls b and c we pass an endless rubber or blanket e for supporting the fabric to be
coated the band è may be tightened. On the frame a at each end thereof we mount
loosely an arm g and to the opposite ends of these arms we pivot a knife or guage
carrying ears h in the ordinary way this knife extends the whole width of the rubber
or blanket e. J is a cylinder or roll which may be heated as shewn. In order to
coat a piece of fabric with waterproof material we proceed as follows :-
i
We cement the two ends of the piece of fabric to be coated so as to form an endless
band K this band we pass over rolls c. b. and also over the roll or cylinder J placed at a
suitable distance according to the length of material to be coated; we then turn the
knife or guage i so as to rest on the cloth K and by any suitable means apply the
waterproof solution or dough the rolls are then put into motion by means of the
pulley 1. and friction pullies mno when the waterproof material will be spread thinly
and evenly and this we continue until the desired thickness is obtained. We would
remark that instead of forming the material to be coated into an endless band we may
coat it in a length by placing one end on the band e and the other over roll J. In
order to form cloth known as double texture we take a piece of cloth (marked in
drawing by the line q) which may form the lining coated as aforesaid and roll it on
the roll p this cloth we pass partly round the roll as shewn and between the rollers r
and c, we then form and coat another piece of fabric in the same way as that last
described and when the last coat is being put on we bring one end of the previously
coated cloth under the roll and upon starting the machine the two cloths during

page_text: their passage between the rolls r and c will be pressed together and the waterproof
surfaces coming in contact will cause them to adhere. We would remark that the
roll is adjustable so that it is only lowered when the last coating is put on (or during
this operation) the second piece of fabric aforesaid. To each end of the axles of the
roll c and doubling roll r we mount loosely pulley wheels SS SS so as to pass bands
to accumulate the pressure between same as required. Fabric treated as above is
vulcanized or otherwise treated in the usual way.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed we declare that what we claim is :—
1st. The use of the rubber or blanket e substantially as and for the purpose
set forth.
2nd. The arrangement of doubling while cloth is endless.
3rd. The general arrangement of machinery substantially as and for the purposes
set forth.
