PROVISIONAL SPECIFICATION.
An Improved Blow-pipe for the use of Gas-fitters.
I, THOMAS JONES 4 Chestnut Place Lansdowne Road Worcester, Tin Plate Worker
do hereby declare the nature of this invention to be as follows:-
This invention consists of a closed hollow cylindrical body about three inches deep and
three inches in diameter which contains a sponge saturated with benzoline or similar
substance. From the top of this compartment rises a quadrant curved pipe about four
inches long fitted at the end with a hollow cone shaped termination through which the
pipe passes entirely. The narrow end of the hollow cone shaped termination does not
fit tight on to the end of the pipe aforementioned, but a very narrow opening is left
all round for the passage of air between the said pipe end and the cone shaped
termination. A tube is now fitted into the base of the hollow cone shaped termination
having a mouthpiece at the extreme end and this tube is a flexible one. The various
parts are so made as to be screwed one into the other for the easy taking and refixing
together of the whole appliance. The pipe aforementioned, is provided with a wick
reaching down to the saturated sponge after the ordinary manner.
When I blow down my tube, and light the lamp the draught will continue the cone
shape, given to it by the determination aforementioned so formed and thus the flame
is blown to a point and the work can be executed in a much neater and cleaner manner
than when an ordinary flame is used as at present.
As my improvements are capable of some modifications without departing from the
principle thereof I do not restrict myself to material dimensions, or to the precise form
or placement of the several parts thereof.

COMPLETE SPECIFICATION.
An Improved Blow-pipe for the use of Gas-fitters.
I, THOMAS JONES, of 4, Chestnut Place, Lansdowne Road, Worcester, Tin Plate
Worker, 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 consists in the herein described improved blow pipe which I will
describe by referring to the accompanying drawing on which
Fig. I represents the said blow pipe in elevation.
Fig. 2 is a sectional elevation and Fig. 3 is a plan of the same.
In Figs. 2 and 3 the flexible tube is represented as broken off.
The said improved blow pipe consists of a closed hollow body a preferably of
cylindrical form and about three inches deep by three inches in diameter which
contains a sponge or other spongy substance saturated with benzoline or similar
substance. From the removable screwed top of this compartment a rises a quadrant
curved pipe c say about four inches long fitted at the outer end with a hollow cons
shaped termination d through which the pipe c passes entirely. The narrow end
of the hollow cone shaped termination d does not fit tight on to the end of the
pipe c but a very narrow opening e is left all round for the passage of air between
the end of the pipe c and the cone shaped termination d; a tube fis fitted into the
base of the hollow cone shaped termination d and to this is fixed a flexible tube f¹
having a mouthpiece g at the extreme end. The various parts are by preference made

page_text: as shewn so as to be screwed one into the other for the easy taking apart and refixing
together of the whole appliance. The pipe c is provided with a wick / reaching down
to the saturated sponge after the ordinary manner.
On blowing down the blast tube f f (the lamp having previously been lighted
at h¹) the air issuing through the opening e will continue the cone shape given to it
by the cone shaped termination d and thus the flame i will be blown to a point and the
work can be exeented in a much neater and cleaner manner than when an ordinary
flame is used as at present.
It will be evident that the mouthpiece 9 may be dispensed with and the pipe f¹ be
connected to receive an air blast from a blower or fan.
The accompanying drawing illustrates what I consider to be the best way for
carrying my said invention into practice but it is to be understood that I do not limit
myself to the material dimensions or to the precise form or placement of the
several parts thereof.
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 blow pipe and in combination with the wick tube and vessel forming
the lamp thereof, the employment of the hollow cone shaped termination d receiving
the air blast and fixed to the wick tube so as to leave a narrow space for the blast
to issue through at the end thereof around the flame for the purpose and substan-
tially as hereinbefore set forth.
2. The combination and arrangement of parts constituting the improved blow
pipe substantially as hereinbefore described and illustrated by the accompanying
drawing.
Dated this 25th day of October 1890.
