Improvements in the Manufacture of India Rubber Waterproof
Garments.
We GOODMAN CHARLES MANDLEBERG, HENRY LESSER ROTHBAND and SAMUEL
LAWRENCE MANDLEBERG of the Albion Rubber Works, Pendleton, Manchester in the
County of Lancaster, Manufacturers of India Rubber Piece and other Goods, do
hereby declare the nature of the said invention to be as follows:-
Our invention relates to the manufacture of india rubber waterproof garments
without disagreeable odour from, textures produced by the process or processes and
materials hereinafter described. The india rubber dough or "mixing" is prepared by
dry kneading the india rubber which is then soaked for about 24 hours in deoderized
petroleum Naphtha having a specific gravity of about 76 degrees of Baums hydro-
meter then it is left in a practically air tight vessel for about 24 hours and during
this time it is stirred occasionally, then it is worked two or three times through
rollers after which the dough or mixing is ready to be applied to any suitable fabric
in the spreading machine (the temperature of which is about 80 degrees Fah.) in the
ordinary manner.
29
The fabric thus proofed is then "cured or vulcanized.
The garments are made from india rubber waterproof fabrics prepared as above
described, the seams are cemented together by a solution of india rubber formed by
rubber and the Naphtha above mentioned and in order that the cementing solution
may be prevented from drying up while in use it is kept in a closed vessel for con-
taining the above named Naphtha and rubber solution and a mixing agitator for
mixing the rubber solution and Naphtha as required, and preventing the latter from
evaporating.
The garments made as above described are hung for a sufficient time in a room at
a temperature of about 80 degrees Fah. when they will become free from odour, and
may then be scented if required by exposing them to some volatile perfume such as
oil of lavender at a suitable temperature.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of India Rubber Waterproof
Garments.
We, GOODMAN CHARLES MANDLEBERG, HENRY LESSER ROTHBAND, and SAMUELl
LAWRENCE MANDLEBERG, of the Albion Rubber Works, Pendleton, Manchester, in
the County of Lancaster, Manufacturers of India Rubber Piece and other Goods,
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:
Our invention relates to the manufacture of india rubber waterproof garments
without disagreeable odour from textures produced by the process or processes and
materials hereinafter described.
The india rubber dough or mixing" is prepared by dry kneading the india
rubber, which is then soaked for about 24 hours in what is commonly known as
deodorized petroleum Naphtha, having a specific gravity of about 76 degrees of Baums

page_text: hydrometer, then it is left in a practically air tight.vessel for about 24 hours, and
during this time it is stirred occasionally, then it is worked two or three times through
rollers after which the dough or mixing is ready to be applied to any suitable fabric
in a spreading machine, (the temperature of which is about 80 degrees Fah.) in the
ordinary manner.
The fabric thus proofed is then "cured" or vulcanized.
The garments are made from india rubber waterproof fabrics prepared as above
described the seams are cemented together by a solution of india rubber formed by
rubber and the Naphtha above mentioned, and in order that the cementing solution
may be prevented from drying up, while in use, it is kept in a closed vessel used for
containing the above named Naphtha and rubber solution and a mixing agitator is
employed for mixing the rubber solution and Naphtha as required and preventing the
latter from evaporating.
The garments made as above described are hung for a sufficient time in a room or
stove at a temperature of about 80 degrees Fah., until they are found to have
become practically free from odour, and they may then be scented if required by
exposing them in the said heated room to some volatile perfume such as oil of
Lavender or other scent giving material at a suitable temperature.
We have herein before referred to the Naphtha solvent as deodorized petroleum
Naphtha meaning thereby, Naphtha which will when used as a solvent, evaporate in
the atmosphere from the material to which it is added, without leaving any appreciable
scent behind; as is well known it is produced by a process or processes ordinarily
used, that is, by washing with acids and alkalies, and then distilling it, the product
thus obtained being a practically deodorized Naphtha solvent.
By a like method similar deodorized or practically scentless Naphtha has also been
produced commercially from coal tar, we therefore use, either Naphtha which has
been deodorized whether obtained from petroleum or from coal tar or other like
source in carrying out our invention, but in the latter case (for coal tar Naphtha) the
stoving heat employed is at an higher temperature than for deodorized petroleum
Naphtha commonly so called.
The drawing hereunto annexed is a vertical section and illustrates an apparatus
which we find may be used with advantage for mixing the cementing solution and
retaining the Naphtha so as to prevent rapid evaporation while being used in
cementing the seams of the garments, other known apparatus may however be
employed.
a,
is the vessel at the bottom of which on one side there is a spout a¹, which can
be covered by a closely fitting cap a², to prevent the escape of the Naphtha spirit.
On the other side at the upper end of the vessel there is also a spout a³, with a closely
fitting cap a¹.
This spout a³, is for filling india rubber and naphtha into the vessel a, the spout a³,
being then covered by a cap a*.
The vessel a, itself, is also covered by a cap a³, which has a boss in its centre to
form the bearing for a vertical shaft b, to pass through, the lower end of which shaft
works in a footstep bearing at the bottom of the inside of the vessel a, this shaft b,
has a boss b¹, secured upon it, carrying propeller blades 62, by which the rubber and
Naphtha are mixed and incorporated together to form the cementing solution, the
upper end of the shaft b, has a handle 63, for rotating it.
a,
There are or may be three or more pins a, projecting laterally from the outside
of the spouts a¹, and a³, and the exterior of the upper part of the vessel
and each cap
is or may be formed with slots (shown in dotted line on the vessel a) in its edge, so
that the lid may be put on and then by a partial rotation, the slots (which are slightly
screw inclined) will engage with the pins (a) and this draws the inside of such lid
(which is or may be faced with a ring (a) of leather or other elastic packing
material) close against the edge or orifice of the spout or edge of the vessel a.
These slots and pins thus act upon the principle of the bayonet fixing.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
--
The manufacture of india rubber waterproof garments free from disagreeable odour
and scented with an agreeable perfume when required, by preparing the cloth or
fabric and making it into garments by the process or processes substantially as
herein before described.
