Complete Specification Left, 7th Dec., 1898-Accepted, 7th Jan., 1899
An Improved Powder Blower or Injector.
I, JOSEF BUCZKOWSKI, trading under the style or Firm of Reithoffer and Nephew,
Successors, of 115, Mariahilferstrasse, Vienna VI, in the Empire of Austria, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a powder blower or injector particularly for insecticide
powder. It is made preferably of pasteboard or the like and may serve as a
container for the powder and be easily adapted for use as a blower or injector for
sprinkling or injecting the powder whenever required.
The powder container convertible into a blower or injector is illustrated in the
accompanying drawings forming part of this Specification where in Figures 1 and 2
represent the device in longitudinal section. It consists of two cylindrical or other
shaped parts (a b) fitting the one in the other, the inner part (a) which is filled with
powder having a conical cap (a¹) adapted to form a nozzle, and a base (a2) provided
with an orifice (a³) covered by a leather or other flap valve (a). The inner part (a)
is adapted to work as a piston in the outer part (b) which is closed at the rear end
and may be provided with an air inlet orifice (61) in the side over which the piston-
like end of the part (b) works so that on the outstroke of the piston air admitted to
the cylinder (b) is compressed therein on the instroke of the piston and forced
through the orifice (a³) and valve (a') whereby powder is ejected from the conical
cap or Dozzle in the point of which an orifice is pierced, when the device is to be
used.
An Improved Powder Blower or Injector.
I, JOSEF BUCZKOWSKI, trading under the style or Firm of Reithoffer and Nephew,
Successors, of 115, Mariahilferstrasse, Vienna VI, in the Empire of Austria,
Manufacturers of Soap and Perfumery, 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 :-
-
The present invention relates to a squirt or ejector for pulverulent substances,
such as insect powder for example, and which may also constitute the receptacle or
passage for containing a definite amount of the powder. This squirt or ejector
consists essentially of two hollow bodies adapted to fit and slide telescopically the

page_text: one in the other and which may be of any desired similar form in cross section, the
inner body that contains the powder terminating in a pointed nozzle or having a
perforated stopper inserted in the same and being provided at its opposite
end with an aperture fitted with a valve-like closing device. Consequently,
if the inner body which is opened at its point or is provided with a per-
forated stopper, be moved to and fro after the manner of a piston within the
other hollow body, an alternate suction and delivery action will be produced, and
at each inward stroke a portion of the powder will be blown out of the nozzle-like
aperture or the hole in the stopper, by the compressed air. which opens the
valve.
The accompanying drawing illustrates in longitudinal section two constructional
forms of the device which can be used both as a casing or package and also as a
squirt or ejector. Figure 1 illustrates the two hollow bodies of a squirt of this
kind made entirely of paper or cardboard in the telescoped condition. Figure 2
shews the said bodies when the powder receptacle is drawn out, its point being cut
off. Figures 3 and 4 illustrate in a similar manner, a squirt the powder receptacle
of which is constructed of a bottle made of glass or porcelain, and closed by a
perforated stopper.
In the construction shown in Figures 1 and 2, the two hollow bodies a and b,
which are adapted to work piston-like the one in the other, are made of cardboard,
paper, or similar material and may be made of a round or polygonal form in
cross-section. The inner body a is provided at its extreme outer end with a
conical or pyramidal extension a¹ which is closed at the point, whilst the other end
is closed by means of a strengthened or thickened bottom a² of wood, paper board,
or the like, and in which there is formed an opening a³. Over the inner surface of
this bottom there is arranged a piece of leather or a strip of other flexible material
which is fixed to the said bottom and acts as a flap valve a¹.
The charging of this hollow body a may be effected either before the bottom a?
is fixed to the same, or it may be effected before the extension at is connected to
the body a. The outer hollow body b, which serves to guide this piston-like
powder receptacle a, consists of a casing of suitable form in cross section which
is closed at one end and which may be formed with a hole 6¹ in its wall for the
purpose of facilitating the entrance of air during the outward stroke in the case of
hollow bodies which fit tightly in each other.
To use the appliance as a squirt, the point of the extension a¹ is opened or cut
off, whereupon by pushing the powder receptacle a to and fro in the casing b, the
powder can at once be blown out.
But
For the purpose of preventing the powder from leaking out, the powder
receptacle à may be made of glass or porcelain, as shewn in Figures and 4
wherein the receptacle a, made of that material, is represented as constructed in
the form of a bottle whose bottom is constituted by'a disc a2 which is formed with
several apertures as and which is connected to the bottle by means of a covering c
of paper or leather fixed to the bottle. In the casing b there, may also be formed,
as in the first described arrangement, an aperture 6' for the entrance of air.
in the present case, however, the bottle a is inserted so loosely in the casing b
that, in pushing the bottle in and out, the air can pass through the narrow space
between the sides of the bottle and the casing. In the mouth of the bottle a there
is inserted a stopper e through the bore e¹ of which the powder is ejected each time
the bottle is pushed into the casing b. The ejection aperture may also be arranged
in the side of the bottle neck and a separate charging opening may also be provided
which is adapted to be closed by a stopper.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A device capable of use as a container or package and also as a squirt or
ejector for pulverulent substances, consisting of two hollow bodies a and b which

page_text: are capable of being telescoped the one in the other and of which the body that
contains the powder terminates in a pointed extension a¹ and is closed at its other
end by means of a perforated bottom a² provided with a flap valve at, so that after
the point has been opened or cut off, the powder contained can be blown out by
moving the inner body or receptacle to and fro in the outer hollow body b.
2. A form of construction of the device specified in Claim 1, consisting in pro-
viding the powder receptacle (which is made of glass or porcelain) with a hole c¹ iu
its closing portion (stopper e) through which hole the powder is ejected as soon as
the receptacle a is moved in and out of the casing b.
