PROVISIONAL SPECIFICATION.
A Blow Tube Pistol.
1, CHARLES HUELSER of the firm of Huelser & Co. of 142 Fleet Street in
the City of London, Solicitors of Patents, do hereby declare the nature of this
invention, a communication to me from abroad by Albert Silbermann of Berlin
in the Empire of Germany, Manufacturer, to be as follows:-
The object of this invention is a pistol actuated by a current of air derived from
the human lungs or produced by rapid compression of a hollow indiarubber ball or
the like.
The construction of the improved air pistol is in the main as follows:-
A detachable barrel is introduced into the fore end of the pistol shaft within
which it is attached to an indiarubber tube the other extremity of which is either
pulled over a mouth piece or connected with an indiarubber ball or the like.
When producing a strong air current in either way, a ball placed into the rear
portion of the barrel is expelled in the direction of the latter, the usual aiming
device being of course provided.
To load the pistol, air is drawn in by the lungs or ball after the muzzle of the
barrel has been placed over the shot. To prevent the latter from penetrating into
the indiarubber tube, a small arm is crosswise bent over a portion of the rear
barrel-end in order to detain the ball or shot which is morcover prevented from
rolling out of the barrel before shooting as might occur when aiming at objects
lying below level. To attain this latter purpose the rear end of the barrel is slightly
bevelled from top to bottom so as to cause the indiarubber tube drawn over this
end of the barrel to enter somewhat into the soul of the barrel. The shot, when
suction produced is moved against the arm above referred to, and thereby
sufficiently clamped fast by the indiarubber tube as to be prevented from
spontaneous falling out and to require an air current of a certain energy to he
moved from its seat, whereby also a favorable initiatory speed is attained.
The shaft is made from a sheet metal strip which is bent U fashion, the two
shanks terminating in front in semi-cylindric portions which are united by a ring
shifted thereover. The bottom shank has two tongue-shaped extensions which are
bent over the barrel and hence joined flatly form together a vertical guiding for
the chimb tube. The latter carries the chimb, and, owing to the outward elastic
tendency of the two tongues, can be displaced with sufficient friction upwardly or
downwardly.
The bottom or cross portion of the sheet metal strip forming the shaft is provided
with an aperture, through which the caoutchouc tube is introduced. Though the
latter is easily accessible within the shaft from the sides, a recess is provided on
each side near the place where the tube and barrel are joined to allow thumb and
forefinger to be put in and the end of the tube to be easily pulled over the
barrel.

A Blow Tube Pistol.
I, CHARLES HUELSER of the firm of Huelser & Co. of Temple Chambers,
London, International Patent Agency, do hereby declare the nature of this inven-
tion a communication to me from abroad by Albert Silbermann of Berlin in
the Empire of Germany, Manufacturer, 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 a pistol which is operated by a current of air produced
by the human lungs or by rapid compression of a hollow indiarubber ball or
the like.
Referring to the accompanying drawing
Fig. 1 is a top view,
Fig. 2 a side view and
Fig. 3 a vertical longitudinal section.
Figs. 4 to 7 represent details of the improved device.

To
The extractible barrel A is introduced into the shaft C, in which it is attached
to the indiarubber tube B, the other end of which is either pulled over a mouth
piece as shewn in the drawing or connected with an indiarubber ball or the like.
When compressing the indiarubber ball with the left hand or producing a strong
air current by blowing through the mouth piece as with a blow tube, while holding
with the right hand the shaft C and aiming over notch and muzzle sight a, a
ball placed into the rear portion of the barrel Fig. 3 is expelled towards the
aim. For loading the pistol, air is drawn in by the lungs or by means of the india-
rubber ball after having placed the muzzle of the barrel A over the shot
prevent the latter from penetrating into the indiarubber tube B, a small arm is
bent up over part of the rear end of barrel A. This arm g arrests the ball, which
is moreover prevented by the following device from rolling out of the barrel before
shooting, which would happen when aiming at objects lying below the level of the
barrel. The latter is for this purpose bevelled at its rear end so that the indiarubber
tube B drawn over this end enters to some extent into the soul of the barrel Figs. 3
and 5. The ball, when suction is produced, is flung against army and is conse-
quently sufficiently clamped fast by the indiarubber tube as to be prevented from
falling out of its own accord, while requiring for its removal an air current of a
certain energy, which results in a favorable initiatory speed.
The shaft C is formed by a sheet metal strip which is bent U fashion and the
two shanks of which terminate in semi-cylindric parts which are united by the
ring d shifted thereover. The lower of the shanks has two tongue-shaped
elongations e, which are first bent over the barrel A. and then bent flat together,
with their ends so as to have some outward elasticity thereby forming the vertical
guiding for the tube. The latter carries the notch and can be vertically displaced
with sufficient friction owing to the outward elasticity of the tongues e.
The bottom plate of the sheet metal strip forming the shaft has a hole c¹ for the
introduction of the caoutchouc tube B. Although the latter is easily accessible
within the shaft from the sides, a recess c is provided on each side of the shaft C
at the place of junction of the barrel and india rubber tube, in order to allow of the
introduction of the thumb and forefinger for drawing the indiarubber tube over the
barrel A.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1) A blow tube pistol, in which an air current derived from the lungs or from
indiaruliber hall or the like is unssed from an india rubber tube B extending

page_text: through the shaft C into the barrel A, which is adapted to be shifted into the front
portion of shaft C, substantially as set forth.
2) In the blow tube pistol forming the subject of Claim 1, the application of an
arm g at the rear end of the barrel for the purpose of arresting the shot i after
having been sucked in, substantially as set forth.
3) In the blow tube pistol forming the subject of Claim 1, the application of a
bevel or slanting at that end of the barrel which is covered by the caoutchouc
tube B, for the purpose of allowing the shot to be clamped fast with moderate
pressure by that piece of the caoutchouc tube which penetrates into the soul of the
barrel, substantially as set forth.
4) In the blow tube pistol forming the subject of Claim 1, the application of a
shaft C made from a sheet metal strip bent U fashion and the semi-cylindric ends
of which are held together by a ring d, substantially as set forth.
5) In the blow tube pistol forming the subject of Claim 1, the method of
forming the guiding for the notch tube f from the two tongues e bent flat together
and having some outward elasticity, substantially as set forth.
