page_text: I, THOMAS GARE of 25 Booth Street, Edgeley, Stockport in the County of Cheshire,
Boot and Shoe Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in blow pipes and has principally for its
object to provide means whereby the flow of air from the blow pipe remains a
continuous one.
The improvements consist in forming in an ordinary blow pipe, near the mouth end,
a partition, and on each side thereof an opening or valve, and surrounding the same
with a flexible bag, reservoir, or equivalent, which will store the air blown in, and
cause the flow thereof not to be interrupted, but to be continuous when taking a fresh
breath.
Instead of working the blow pipe by the mouth, a flexible ball may be fitted to the
respective end thereof, and the orifice of the pipe and flexible ball provided with an
in and outlet valve, respectively.

page_text: I, THOMAS GARE of 25 Booth Street, Edgeley, Stockport in the County of Cheshire,
Boot and Shoe Manufacturer, 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 relates to improvements in blow-pipes and has principally for its
object to provide means whereby the flow of air from the blow-pipe remains a
continued one.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a longitudinal section and Fig. 2 partly side elevation and partly a
longitudinal section of my improved blow-pipe.
In carrying out my invention and referring to Fig. 1 I form in an ordinary blow
pipe a near the mouth end thereof, a partition b, and on each side of the latter, an
opening or valve c, e surrounded by a flexible bag d, reservoir or equivalent, which
may either be fastened or slipped loosely onto the blow-pipe a and which serves to
store the air blown in, and cause the flow thereof not to be interrupted but to be
continuous when taking a fresh breath.
The air blown in at e enters the tube a, and being arrested by the partition b is
caused to pass through the opening or valve c and enter the flexible bag d, until it is
fully filled and expanded, see dotted lines.
As soon as the supply of air to the flexible bag d or its equivalent is discontinued
the valve c by the pressure of air in the bag or its equivalent, closes its opening and'
enters the pipe a on the other side of the said partition through the opening c¹,
which if deemed necessary may also be provided with a valve, from whence it passes
direct to the outlet of the blow pipe a.
с
The size of the opening or valve c is made rather larger than the opening or valve c¹
so as to permit of a quick inflating of the flexible bag d, reservoir or its equivalent,
while the blast produced will be a gentle and continuous one.
Instead of working or supplying the blow pipe with air by means of the mouth, a
flexible ball or suction bag see Fig. 2, may be fitted to the respective end thereof,
preferably by means of a flexible tube
J.
This flexible ball or suction bag is formed with an opening or inlet valve g¹ and
the flexible pipe g or ball or bag with an outlet valve h.
In order to inflate the flexible bag d, reservoir or its equivalent attached to the
blow pipe a,
the opening g in the flexible ball or suction bag f is closed by placing the
finger thereon, and the flexible ball or suction bag, is at the same time compressed
by the hand, thus causing the air contained therein to open the valve h, and enter the
pipe g, which conducts it to the blow pipe a and its flexible bag d, as bereinbefore
described.
When the opening g' is freed, the valve closes and prevents the return of the air.

page_text: This operation is continued until sufficient air has accumulated in the flexible
bag d, reservoir or its equivalent, in this case, however, the valve c in the flexible
bag d reservoir, or its equivalent, is dispensed with owing to the valve h in the pipe g
or flexible ball or suction bag preventing the return of the air.
The blow-pipe described herein before, and shown in Fig. 2, is of great service where
there is not enough room to admit of it being supplied with air by the mouth of the
user, as the blow pipe may be held against the object to be operated upon by one hand,
and the flexible ball or suction bag, some distance away from the same, by the other
hand, and a small lamp suspended from the end of the blow-pipe, in place of holding
a candle, if found necessary.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed. I declare that what I

Having now particularly described and ascertained the nature of my inven-

claim is :-
In blow pipes
1st. Providing the pipe a with a flexible bag d, reservoir, or its equivalent, opening
or valves c & c', and partition b, in connection therewith, for the purpose of storing
the ingoing air, and afterwards ejecting the same through the outlet of the pipe a,
substantially as set forth.
2nd. The combination of a blow-pipe formed as specified in the preceding claim,
with a flexible ball or suction bag, by means of the pipe g., substantially as and for
the purpose specified.
