Improvements in Blow Pipes.
We HERBERT SQUIRE and GEORGE WALTER SQUIRE both of 79, Copenhagen
Street Barnsbury, Electricians, do hereby declare the nature of this invention to be
"as follows:-
Our invention relates to improvements in blow pipes and consists chiefly of a
plumber's blow pipe of improved construction, allowing easy access to be obtained
to joints which have to be made in pipes passing along corners or other similar
places not conveniently accessible.
In carrying our invention into practice we provide a box or casing surmounted by
a bent tube into which extends a central pipe of small diameter terminating at its
upper end into a point and extending at its lower end to the bottom of the said box
or casing whereat it is twice bent over at right angles and connected to the central
end of a lower ball or bulb communicating by a tube with an upper ball or bulb
furnished with a valve and compressed by a bar pivotted at its upper end to a
bracket fixed to the inside of the box or casing and connected near its lower end to
a T. or thumb piece extending outside through an opening formed in the said box
or casing and serving likewise as an air inlet. The bent tube aforesaid is connected
to a gas inlet furnished with a tap or to a spirit torch so that the blow pipe may be
operated either by means of gas or of spirit.

Improvements in Blow Pipes.
WE HERBERT SQUIRE and GEORGE WALTER SQUIRE both of 79 Copenhagen
Street Barnsbury Electricians 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 improvements in blow pipes and consists chiefly of a
plumbers blow pipe of improved construction allowing easy access to be obtained to
joints which have to be made in pipes passing along corners or other similar places
not conveniently accessible.
In carrying our invention into practice we provide a box or casing surmounted by
a bent tube Å into which extends a central pipe B of small diameter terminating at
its upper end into a point C and extending to its lower end to the bottom of the said
box or casing whereat it is twice bent over at right angles and connected to the
central end of a lower ball or bulb D communicating by a tube with an upper
ball E or bulb furnished with a valve F and compressed by a bar G pivotted at its
upper cad to a bracket H fixed to the inside of the box or casing and connected
near its lower end to a T or thumb piece I extending outside through an opening
formed in the said box or casing and serving likewise as an air inlet. The bent
tube aforesaid is connected to a gas inlet J furnished with a tap K or to a spirit
torch L so that the blow pipe may be operated either by means of gas or of
T
.

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.
A compact mechanical method of gaining the force of air required by plumbers
gasfitters and general mechanics.
The operator being able to use this said tool while held in one hand and by an
alternate pressure on Tor thumb piece I compressing upper rubber ball or bulb E
inflates lower rubber ball or bulb D which discharges itself into small central tube B
that ends at its upper end into point C.
