PROVISIONAL SPECIFICATION.
Improvements in connection with India Rubber Solution Injectors.
We, WILLIAM BowN, 308 Summer Lane, Birmingham in the County of
Warwick, Manufacturer and GEORGE CAPEWELL, Upper Thomas Street, Aston
juxta Birmingham aforesaid, Machinist, do hereby declare the nature of this
invention to be as follows:-
:-
This invention has reference to injectors for injecting the india rubber solution
used when repairing a puncture in a pneumatic tyre and for other like purposes,
and our improvements consist in forming a suitably shaped case or receptacle and
placing therein a plunger or ejector for forcing the solution out at the nozzle end
of the said case or receptacle. Formed at the other end of the case or receptacle
is a slot or guide through which a pusher or thumb piece projects, which said
pusher or thumb piece is formed out of or connected to the plunger or ejector and
is used for operating the said plunger or ejector. Or we may dispense with the
slot or guide formed in the case or receptacle and use instead an independent
piece of tube or other suitably shaped guide, slotted or otherwise for the thumb
piece to work up and down in. We may also provide the case or receptacle with a
sliding needle or equivalent which passes through the point or nozzle for inserting
into the punctured part of the tyre or other article. The said needle is by preference
fluted at its point for facilitating the delivery of the solution.

Improvements in connection with India Rubber Solution Injectors.
We, WILLIAM BOWN, 308 Summer Lane, Birmingham in the County of
Warwick, Manufacturer and GEORGE CAPEWELL, 114 Upper Thomas Street,
Aston juxta Birmingham aforesaid, Machinist, 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 has reference to injectors for injecting the india rubber solution
used when repairing a puncture in a pneumatic tyre and for other like purposes.
In order that our invention may be clearly understood we have illustrated the
same on the annexed sheet of drawings.
A is the case or receptacle in which is placed the plunger or ejector B for forcing
the solution out at the nozzle a. Formed at the other end of the said case A is the
slot or guide b through which the pusher or thumb piece e projects, the said
pusher c being formed out of or connected to the plunger B and used for operating
the said plunger B. It will be easily understood that when the pusher c is moved
along the slot bit will cause the plunger B to travel down the case A thereby ejecting
the solution.
Fig. 2 shews another method of carrying our invention into practice, in this case
we dispense with the slot or guide formed in the case A and use instead the

page_text: independent screwed guide piece C (or the guide piece C may have a plain surface)
slotted or otherwise for the thumb piece d to work up and down on.
We may when desired provide the nozzle a with a fluted sliding needle made to
slide in and out in any suitable manner, or the said nozzle a may be made to slide
in and out instead.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we would have it understood
that we do not limit ourselves to the precise details as herein shewn and described
as they may be varied without departing from the nature of our invention, but what
we wish to claim is :-
:-
The means substantially as herein shewn and described or their equivalent for
ejecting rubber solution or other like substance.
