COMPLETE SPECIFICATION.
An Improved Weapon for Projecting Liquids.
I, CHARLES JACOB KINTNER, of No. 45, Broadway, New York City, County and
State of New York, United States of America, Electrical Expert, 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 is directed to portable weapons of the nature indicated and is
especially adapted for use in connection with bicycles, or by persons desiring to
defend themselves against the attacks of savage dogs or vicious persons, and is herein
illustrated and described in the specific form of a pistol, although it may take other
forms in its application, as for instance that of a gun, or in fact any shape or form
adapting it for use as a portable weapon of defence.
The invention will be fully understood by referring to the accompanying draw-

Figure 7 is a longitudinal sectional view of a modified form of the implement,
illustrating also a novel form of pump attached thereto.
Referring now to the drawings in detail and first to Figures 1 to 5 inclusive ;-
13' represents a containing chamber, preferably in the form of a pistol and shown
in the figures just referred to as of a single piece of glass, metal, or the like, the
major portion of said containing chamber being the grip part of the apparatus
and designed to hold a liquid L such as ammonia in solution. The outer end of
this chamber is screw-threaded interiorly for the purpose of receiving, through the
agency. of a screw-head D, the ordinary form of bicycle valve V used in connection
with the inflation of bicycle tyres; 2 being a rubber or equivalent washer or
packing for the purpose of rendering the junction between the part D and the
barrel B of the chamber B' absolutely air-tight.
C is a screw-threaded cap containing in its inner surface the usual packing w¹ wa
which seals and protects the outer end of the valve V. P is a curved tube, pre-
erably of metal, adapted to fit within a groove in the front side of the grip and

page_text: to have its lower end extend to the extreme bottom on the inner side of the
containing chamber and sealed therein by any sealing material c, the free end of
the tube lying in close proximity to the barrel portion B of the chamber and being
surrounded by a soft rubber tube P1, the other end of which in turn surrounds
a nozzle N. The free end of the tube P, the rubber tube P and nozzle N are held
firmly compressed in a groove on the under side of the barrel B by a metallic
shield A of substantially semi-circular form, said shield having lateral lugs or
ribs a a adapted to be slid endwise into corresponding grooves in the sides of the
barrel B.until it, the shield, abuts against a head b extending around the barrel,
see Figures 1 and 5. This part A is of sufficient thickness at its front end to act
as a support for a trigger-guard G and is provided near its centre with side lugs
or ears a a¹ which pivotally support, by a pivot pin t, a trigger T, the upper end T¹
of which is of such curvilinear structure in cross section as to effectually pinch or
squeeze the soft rubber tube P¹ when held in its forward position under the
influence of the strong retractile spring S secured to the forward part of the
shield A by screws a; S¹ being an adjustment screw located between the forked
ends of the trigger-guard, as clearly shown in Figures 2 and 3, for the purpose of
regulating the pressure of the spring S upon the part T of the trigger T. a² a² are
external projections in one side of the shield A having internal screw-threads
adapted to receive set-screws s¹s for the purpose of securing the shield A firmly
in position.
It will be noticed that the rear end of the trigger-guard G is curved upward and
outward. This is for the purpose of affording a yielding catch or support for the
device when carried or supported by the handle bars H of an ordinary bicycle.
The parts of the apparatus having been put together in the manner indicated, its
operation is as follows:-The cap C and valve V are unscrewed from the free end
of the barrel B and sufficient water or other liquid, such as ammonia in solution,
is placed therein, as indicated by the letter L, Figure 3.
The valve V is now restored to its former position and rendered air-tight by secur-
ing it against the washer or packing w, after which an ordinary bicycle pump is
attached, in the usual manner, and operated so as to fill the barrel B with air under
pressure, the adjustment of the trigger T T having been first effected by the
spring S and set-screw S¹. The bicycle pump is then removed and the cap C
screwed firmly home, as shown in Figures 1 and 3.
The apparatus is now ready for use and is operated by simply holding it after
the manner of a pistol and actuating the trigger TT, thereby allowing the com-
pressed air to force the liquid L forward through the tube P and out at the
nozzle N after the manner of well known forms of bottle siphons; the arrangement
being such that when the apparatus is held in the ordinary position for use, the
compressed air will always tend to force the liquid L toward the bottom of the
chamber B upward and outward through the tubes P P and nozzle N. After
the implement is filled and charged, as described, when it is desired to use it in
connection with a bicycle, the rider simply hangs it on the handle bars H by the
trigger-guard G where it is of ready access for him or her in the event of being
attacked by dogs or vicious persons.
In the modified form shown in Figure 7 the grip part B is cast or blown as
before in one solid piece with two screw-necks N1 N2, the lower or base portion
being open and provided with a door D hinged at Z, said door having on its inner
surface a rubber or other pliable surface R adapted, when closed, to abut snugly
against an internally projecting head or lip ; L' being a latch hinged to the door
at Q, and K a lug or button integral with the grip part B¹, the arrangement being
such that when the door is closed and the latch secured firmly in position the
interior chamber will be air and water-tight.
In this form of the apparatus the tube P is of the solid piece and extends into
the barrel part B through the screw-neck N2, its outer end being held or sustained
by a shield A which is slipped over the tube and screw-threaded to the neck N2,
.

page_text: said shield having side openings for receiving a rotary valve or cock V₁ snugly
fitting within an expanded portion of the tube P, the trigger T being pivotally
secured at t and having an arm T slitted to receive a pin v at the outer end of the
cock or valve V, see Figure 6. S is the trigger spring secured to the part A by
screws s and adapted to hold the trigger in its forward position against a stop P.
secured to one of the lugs or ears to which it, the trigger T, is pivoted.
G is the trigger-guard secured, as before, to the part A and constitutes as in the
first instance a spring actuated support for the implement around an ordinary
bicycle, handle H, or if preferred, this support may extend in reverse direction as
shown in dotted lines at G¹, said support in this instance being split or forked
at its outer or free end to admit of the passage of the liquid between said forks;
or this holding device in either of the modified forms, if preferred, may be attached
to the upper side of the grip or barrel and have the appearance of the hammer of
an ordinary pistol.
With this modified form of the invention is provided a pump which is designed
to be permanently attached to the outer end of the grip part 1 by screw-threads
which secure it to the screw-neck N¹ and in alignment with the valve V which is
permanently secured in said screw-neck. This pump, as herein disclosed, is of
valveless form and consists of a barrel part with a hollow piston rod T having
a piston P2 provided with packing d and a bearing t¹ at its outer end screw-threaded
in the inner surface of the barrel. This bearing t has openings e to admit of the
escape of air as the piston P2 is drawn out. The outer end of the piston rod T
is in the form of a head H' screw-threaded interiorly and adapted to be secured,
when not in use, by exterior screw-threads on the outer end of the barrel. The
barrel of the pump is secured to the screw-neck N¹ bv screw-threads as shown, r
and r being rubber or analogous packing rings, and 2 a seal between the pipe P
and screw-neck N2 to render it water and air-tight.
In the use of this modified form of the apparatus, the liquid is placed in the grip
or base portion through the door D, after which it is closed, and if preferred, salts
of ammonia, N H³, or any other material may be placed within the liquid. The
handle portion H' of the piston rod T" is unscrewed from the barrel of the pump
and the piston drawn out until P2 comes into mechanical contact with the bear-
ing t. The palm of the hand is then placed firmly over the opening 0 so as to
render it air-tight and the piston rod forced inward, thereby causing air to enter
the chamber through the valve V. This operation is continued until the desired
pressure is attained in the barrel B3 above the liquid L in the containing chamber B¹.
This modified form of the implement is used as before by actuating the trigger T
and causing the rotary cock or valve VI to rotate until its valve opening o is in
alignment with the interior of the tube P, when the liquid will flow out under
pressure in the direction of the arrows and between the forks of the holding or
sustaining device G¹.
This invention is not limited to the particular form of apparatus herein shown
and described for throwing or discharging liquids under pressure for the purpose
of frightening away dogs or vicious persons, as it is believed to be broadly new
to utilize compresed air or gas and a liquid in such manner to eject the same from
a containing vessel upon the principle embodied in the ordinary bottle siphons of
commerce and in the application of this generic principle lies the essence
of this invention without regard to any special form of apparatus, so long as the
same be portable and controlled by a valve within easy access of the user.
