PROVISIONAL SPECIFICATION.
An Improved Self Contained Puncture Repairing Outfit for Repairing
Pneumatic Tyres.
I, THOMAS ROWLEY, of 41, Corporation Street, Manchester, in the County of
Lancaster, Consulting India Rubber Expert, do hereby declare the nature of this
invention to be as follows:-
The improvements which form the subject of this invention relate principally
to a combination whereby the requisites for repairing punctures in pneumatic
tyres may be contained in and be applied from a tube, also to dispense with the
necessity of employing sand paper prior to the application of a patch, and in some
cases the use of solution for fixing the patch over the puncture; a part of my
said invention may however be used independently.
For the purpose of this invention I form an open ended tube whose internal
diameter is preferably the same size as the diameter of a patch such as is
ordinarily employed for placing on a puncture in a pneumatic tyre. I provide
a plug or stopper at one end of and projecting from said tube so that it can be
pushed in or withdrawn therefrom.
I place within the tube any preferred number of patches with a parting leaf of
tinfoil or other suitable substance between each, the last patch being level with
the open end of the tube; said patches may be prepared on the face side so as to
adhere when applied to an indiarubber tube.
In order to prepare the tube for the reception of the patch, I employ a compo-
site pencil formed of certain abrasive substances hereinafter defined, with glue
as a base, and fit said pencil into a short tube of an internal diameter that will
slip on to or within the tube hereinbefore described, so that the inserted end of
the composite pencil may cover and protect the patches contained therein, the
opposite end of the composite pencil projecting from the outer end of the tube
in which said pencil is fitted. I form the aforesaid pencil by mixing with glue
or other gelatinous substance, lime, plaster of Paris and sugar, to which water is
added, the following proportions or thereabouts being preferably employed:
Glue 12 parts, lime 24 parts, plaster of Paris 8 parts, sugar 4 parts, water
16 parts.
The mixture is well worked and formed into pencils of convenient size which
when dried become hard.
A small amount of colouring may be added to the mixture if desired. Although
I prefer to employ the materials I have named in the manufacture of the pencils,
I may vary the composition by mixing with the glue or other gelatinous sub-
stance, either pumice, emery, or other abrasive substance either in combination
with or in substitution for lime, or I may employ fish glue in the proportion
of S parts to 10 parts of lime. I place within the tube between the stopper
and the aforesaid patches either a coil spring, or a tube or tubes of colouring
matter for detecting punctures in pneumatic tyres as described in the Specification
of the Patent No. 20,194 of 1896, or sticks formed from the same material which
may be dissolved in water. or a tube containing solution, or any or all of the
1 mor he convenient.

page_text: In the application of my invention when a puncture is indicated and a patch
is to be placed thereon, the sulphur is removed from the spot by moistening the
end of the aforesaid pencil and rubbing the tube with the moistened end until
the rubber is revealed; the tube with the pencil attached is then taken off and
the tube containing the patches is placed on end over the puncture: the stopper
is then pressed and when the pressure is withdrawn the tube is lifted off, leaving
one patch affixed over the puncture; the cover may then be replaced at once
without further trouble.
L
I make the patches herein before named of stockinette coated with india rubber.
The preparing pencils may, be employed independently of the case or they |
may form the plug or stopper herein before described and a cap placed on the
opposite. end of the tube to protect the patches.

Pneumatic Tyres.
1, THOMAS ROWLEY, of 41, Corporation Street, Manchester, in the County of
Lancaster, Consulting India Rubber Expert, 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:-
The improvements which form the subject of this invention relate principally
to a combination whereby the requisites for repairing punctures in pneumatic
tyres may be contained in and be applied from a tube, also to dispense with the
necessity of employing sand paper prior to the application of a patch, and in some
cases the use of solution for fixing the patch over the puncture; a part of my
said invention may however be used independently.
In the accompanying drawing the sectional views which are drawn to an en-
larged scale are illustrations of my invention, similar letters referring to similar
parts in the several views.
For the purpose of this invention I form an open ended tube as a whose
internal diameter is preferably the same size as the diameter of a patch such as
is ordinarily employed for placing on a puncture in a pneumatic tyre. I place
within said tube any preferred number of patches c with a parting leaf of tinfoil
or other suitable substance between each the last patch being level with the open
end d of the tube said patches may be made of stockinette coated with rubber
and may be prepared on the face side so as to adhere when applied to an india
rubber tube. A cap e is formed to fit on to the open end of the tube and cover
the aforesaid patches: I form a plug b that will slide in at the opposite end of the
tube the inner end of said plug resting on the patches c; said plug may be
either solid as in Fig. 1, or may be formed hollow as in Fig. 2, so as to contain
either colouring matter for detecting punctures in pneumatic tyres as described
in the Specification of the Patent No. 20194 of 1896 or a tube of solution. In
order to prepare the air tube in a pneumatic tyre for the reception of the patch I
form a composite pencil ƒ by mixing with glue or other gelatinous substance,
lime, plaster of Paris. and sugar, to which water is added, the following propor-
tions or thereabouts being preferably employed: Glue 12 parts, lime 24 parts.
plaster of Paris 8 parts, sugar 4 parts, and water 16 parts. The mixture is well

page_text: worked and formed into pencils of convenient size which when dried become
hard. A small amount of colouring matter may be added to the mixture if
desired and I may vary the composition by mixing with the glue or other
gelatinous substance either pumice, emery, or other abrasive material in com-
bination with or in substitution for lime or I may employ fish glue in the propor-
tion of 8 parts to 10 parts of lime. I screw or otherwise fit said pencil into the
aforesaid plug, the pencil acting as a stopper if the plug is in the form of a bottle
as in Fig. 2, and the plug serving as a handle for the pencil: a cap y is placed
on the tube a and covers the pencil.
In the application of my invention when a puncture is indicated and a patch
is to be placed thereon, the sulphur is removed from the spot by moistening the
end of the aforesaid pencil and rubbing the air tube with the moistened end
until the rubber is revealed; the cap d is then removed and the end of the tube
containing the patches is placed on end over the puncture; the pencil forming
the stopper of or is attached to the plug b is then pressed and when the pressure
is withdrawn the tube is lifted off leaving one patch affixed over the puncture,
when the cover of the pneumatic tyre may be at once replaced without further
trouble.
The preparing pencils hereinbefore described may be employed independently
of the case in the form shown in Fig. 3, the pencil f being fitted in a case as a¹
with a removable cap a².
Having now 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:-
1. An improved self contained puncture repairing outfit for repairing pneu-
natic tyres formed by the combination substantially as herein before described.
2. A pencil or stick for removing the sulphur from the india rubber air tube
at the part requiring repair that is composed of the several ingredients and in
the manner substantially as herein before described.
