Improvements in Apparatus for Spreading Waterproofing Material
upon Fabrics and for other similar purposes.
I, JOHN JAMES MANN, of 11, Boulevard des Italiens, Paris, France, Engineer,
do hereby declare the nature of this invention to be as follows:
This invention relates to machinery or apparatus employed for spreading water-
proofing or other like material or composition upon woven or other fabrics.
,,
The principal object of the invention is to construct a machine for the above
purposes to and from which the fabric to be treated can be taken upon a "batch
or roller, and which can be run without stopping to remove and replace the said
fabric, another object being to diminish the space required for and the time
required by the use of spreading machines of the above description where a long
drying surface is necessary.
According to this invention I provide at the front of the machine a suitable
spreading device, and tension roller or rollers to keep the fabric tight and smooth
beneath the spreader; immediately behind the latter I fit suitable means for drying
the fabric after each coating has been applied thereto.
For this purpose however I propose to modify the usual drying device and to use
two steam chests or pairs of steam chests placed one above the other in a suitably
long casing or hood closed at the rear end and provided at the top with an outlet
from which the vapors can be exhausted by a fan or similar device; and driven
guide rollers at each end of the chests are arranged in such a manner as to pass
the fabric four times through the casing or hood.
At the rear end of the machine is a pair of delivery rollers between which the
coated and dried fabric is passed from the above or other suitable drying device,
and also a second pair of delivery rollers by which the fabric is delivered to a
convenient plaiting down device by which it is also returned towards the front end
of the machine and guided by rollers and rods to the tension roller above described.
This plaiting down and returning device may consist of a curved and inclined
plane upon which the fabric is delivered, and as it moves down the curved end
of the plane takes the form of plaits or folds from which it is readily drawn by
the tension roller at the front of the machine.
The rollers or "batches" for letting off the fabric to be coated and for winding
up the fabric when completely coated are conveniently placed also at the rear
end of the machine, so that when the machine is first started, the fabric is first
passed through the pair of delivery rollers second above described (which revolve
quicker than the first pair) and is thereby delivered in folds upon the incline along
which it travels towards the front of the machine; it is joined to a suitable
threading in cloth and its end is carried through the machine to the first pair of
delivery rollers by which it is delivered after having received a first coating of
the waterproof or similar material which has been thoroughly dried by the steam
chests.
By this time the whole piece has been delivered and plaited down by the second
Z

page_text: pair of delivery rollers, which is thrown out of action before the delivery of the
extreme end of the piece; the coated and dried end can be severed from the
threading in cloth and joined at leisure to this last extremity of the piece and
the delivery and plaiting down recommenced, and as this is effected more quickly
than the delivery of the coated and dried fabric, the slack cloth between the two
pairs of delivery, rollers will be taken up. During the passage of the fabric under
treatment in this endless form the quickly driven delivery roller can slip beneath
the fabric without injury thereto.
When the first end of the fabric has been completely coated it is severed from
the rear end immediately after leaving the first delivery rollers, and the second
delivery rollers are again stopped;. the finished fabric can be wound upon the
taking up roller or batch," and the end of a fresh piece taken from its roller
and joined to the rear end of the fabric which is being finished; the delivery
and plaiting down rollers are then started again, the fabric being finished acting
as a threading in cloth to the fresh uncoated fabric, which can in its turn be
completely coated as above described and carry another fresh piece through the
machine, which thus need not be stopped although the fabrics are brought to and
removed from the machine on batch rollers and receive several coats of waterproof
material.
By using the two steam chests or series of chests one above the other the fabric
may be passed around and between them and the drying may be effected within a
smaller space than was possible when only one steam chest (or series of chests)
was used; and being also enclosed in a cover or hood, the fabric can be passed
through the machine more quickly than before, as one steam chest or series of
chests will help to keep the other hot.

Improvements in Apparatus for Spreading Waterproofing Material
upon Fabrics and for other similar purposes.
I, JOHN JAMES MANN, of 11, Boulevard des Italiens, Paris, 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:—
This invention relates to machinery or apparatus employed for spreading water-
proofing or other like material or composition upon woven or other fabrics.
The principal object of the invention is to construct a machine for the above
purposes to and from which the fabric to be treated can be taken upon a "batch "
or roller, and which can be run without stopping to remove and replace the said
fabric, another object being to diminish the space required for and the time
required by the use of spreading machines of the above description where a long
drying surface is necessary.
The invention will be readily understood from the following description on
reference to the accompanying drawings.
Figs. 1 and 1 show the two ends of a machine made according to this invention.
I provide at the front of the machine a suitable spreading device a a¹, and
tension roller or rollers to keep the fabric tight and smooth beneath the
spreader a¹; immediately behind the latter I fit suitable means for drying the
fabric after each coating has been applied thereto.

page_text: For this purpose however I propose to modify the usual drying device and to use
two steam chests or pairs of steam chests c c¹ placed one above the other in a suitably
long casing or hood d closed at the rear end d¹ and provided at the top with an
outlet from which the vapors can be exhausted by a fan or similar device; and
driven guide rollers e e¹ e², e³ at each end of the chests are arranged in such a
manner as to pass the fabric four times through the casing or hood d.
At the rear end of the machine is a pair of delivery rollers f between which
the coated and dried fabric a is passed from the above or other suitable drying
device, and also a second delivery roller g or pair of delivery rollers by which the
fabric is delivered to a convenient plaiting down device by which it is also
returned towards the front end of the machine and suitably guided say by
rods h, h¹, h2, h³ and roller h to the tension roller b above described.
This plaiting down and returning device may consist of a curved and inclined
plane upon which the fabric is delivered by rollers g', and as it moves down
the curved end i of the plane takes the form of plaits or folds from which it is
readily drawn by the tension roller b at the front of the machine.
The rollers or "
batches" k for letting off the fabric to be coated, and 7 for
winding up the fabric & when completely coated are conveniently placed also at
the rear end of the machine as shewn, so that when the machine is first started,
the fabric æ is first passed over the delivery roller g second above described (which
revolves quicker than the pair f) and is thereby delivered in folds upon its
incline along which it travels towards the front of the machine; it is joined
to a suitable threading in cloth and its end is carried through the machine to the
first pair of delivery rollers f by which it is delivered after having received a first
coating of the waterproof or similar material which has been thoroughly dried
by the steam chests.
By this time the whole piece has been delivered and plaited down by the
second delivery roller which is thrown out of action before the delivery of the
extreme end of the piece; the coated and dried end can be severed from the
threading in cloth and joined at leisure to this last extremity of the piece and
the delivery and plaiting down recommenced; and as this is effected more quickly
than the delivery of the coated and dried fabric, the slack cloth between the
delivery rollers f f and g will be taken up. During the passage of the fabric
under treatment in this endless form the quickly driven delivery roller g can slip
beneath the fabric without injury thereto.
When the first end of the fabric has been completely coated it is severed from
the rear end immediately after leaving the first delivery rollers ff, and the second
delivery roller g is again stopped; the finished fabric a can be wound upon the
taking up roller or "batch", and the end of a fresh piece taken from its roller k
and joined to the rear end of the fabric which is being finished; the delivery
rollers ff and 9 and plaiting down rollers g₁ g₁ are then started again, the
fabric being finished acting as a threading-in cloth to the fresh uncoated fabric,
which can in its turn be completely coated as above described and carry another
fresh piece through the machine, which thus need not be stopped although the fabrics
are brought to and removed from the machine on batch rollers k and 7 and receive
several coats of waterproof material.
By using the two steam chests or series of chests c c¹ one above the other the
fabric may be passed around and between them and the drying may be effected
within a smaller space than was possible when only one steam chest (or series
of chests) was used; and being also enclosed in a cover or hood & the fabric can
be passed through the machine more quickly than before, as one steam chest or
series of chests c will help to keep the other chest or chests c¹ hot.
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. In a machine for spreading waterproof and similar material upon fabric

page_text: the combination with spreading and drying devices and means for returning the
cloth in a loose condition from the drying to the spreading device, of a double
system of delivery rolls, one for taking the cloth from the drying device and
the other for delivering it loose to be conveyed to the spreading device, and also
a roller removable and changeable for letting off fabric and a removable and
changeable roller for winding on fabric, so arranged that a succession of fabrics
can be brought to the machine coated thereby and removed therefrom one after
the other without once stopping the machine, substantially as described.
2. The improved apparatus or machine for spreading waterproof or similar
material upon fabrics constructed substantially as hereinbefore described and
illustrated by the annexed drawings.
