LIQUID MAGAZINE-PISTOL.
Specification of Letters Patent.
Patented July 6, 1909.
Application led April 6, 1909. Serial No. 488,198.
ication.
This invention relates to portable devices for throwing or discharging liquids in the form of a stream, and is intended for use in defense against the attacks of savage dogs or other animals or of vicious persons by expelling` a liquid which will blind the eyes for a time without danger ofproducing death or of doing any permanent injury. The preferred, 'liquid will e dilute aqua-ammonia, or a tinc-- ture of capsicum and croton-oil, of about six drains of oil to a quart of tincture of capsicuIn, or any other liuid which will be immediately blinding without causing any permanent injury to the eyes.
The object of the invention is to provide such a device in pistol form adapted for 'cone venient carrying in the pocket, and to provide a simple, inexpensive, and effective device of the above character which will be capable of discharging a number of charges of liquid before the contained supply is eX- hausted.
I do not desire to confine myself to any particular form of weapon for ejecting a iquid, but have here illustrated and will proceed to describe the device which I have invented for the above purpose.
Referring to the accompanying drawings, Figure 1 is a longitudinal vertical sectional viewr of my invention with the holding-chamber or magazine full of liquid preliminary to a first discharge, and Fig. 2 is a like sectional view with the plunger or piston drawn back ready for a discharge.
3 is a cylinder having a reduced outer end or nozzle 4, and 5 is a piston or plunger having a reciprocating travel in said cylinder.
6 is a head on the inner end of the piston 5, of slightly larger diameter, and it .has a socket 7 forming a seat for one end of a spirally wound spring 8. The opposite end of the spring 8 has its bearing against the inner end 9 of the cylinder 3. The head 6 has a sleeve 10 fastenedV to it and extending forward and making a loose t around the piston 5. The bore of the cylinder 3 is increased between the points 12 and 14 somewhat to receive the head 7 and sleeve 10 Withfa close sliding fit which is calculated to prevent the passage of liquid between the cylinder 3 and r sleeve 10.
Attached to the under side of sleeve 10 and head 7 is a hollow trigger 14 which extends outside of the enlarged portion of the cylinder 3 through a slot 15 provided for that purpose. The length of slot 15 determines the longitudinal movement of the piston 5. The spring 8 holds the trigger normally against the outer A end of slot 415, in which position the piston 5 is in contact with the inner wall of thenozzle 4 as shown in Fig. 1. The hollow interior of the trigger 14 is in communication through the hole 16 with the space between the sleeve 1() and piston 5 whereby any liquid working back through the space between the piston and sleeve will drain into the hollow trigger instead of leaking into the pocket of the person carrying the pistol. Y
17 is a cap Oscrew in the lower end of the trigger by the removal of which the interior of the trigger will bezdrained and emptied.
20 is a li uid-holding chamber or reservoir extending ongitudinally of the cylinder 3 above the latter;` Its front end is closed by means of a screw plug 21 which is removed for the purpose of filling the reservoir with liquid.
22 is a porthole through the top wall of the cylinder 3 through which the liquid in the reservoir 2O is introduced into the cylinder 22 when the piston 5 is retracted to the position shown in Fig. l2. It will be noted that the port 22 is adjacent the end of piston 5 when the latter is retracted and the quantity of liquid which can be thrown by the piston at a single discharge is measured by the distance of the port 22 from the inner wall of nozzle 4.
The operation of my invention is readily ap arent. After the reservoir 20 is filled the cylinder or barrel of the pistol 3 is automatically loaded by retracting the piston 5 until it is stopped by contact of trigger 14 against the rear end of slet 15. The charge in the cylinder or barrel 3 is forcibly discharged by the expansion of spring 8 simply by the release of trigger 14. Any back-seepage of the liquid around the piston 5 between the latter end walls of cylinder 3 will escape between sleeve 1G and the piston 5 into the hollow trigger 14.
The trigger-guard 26 and handle 27 are of any usual and convenient form for the usual purpose of such parts.
llO
mal outward closed Havin thus fully described my invention what I c aim as new and wish to secure by Letters Patent of the United States, is-
1. In combination with a liquid throwing pistol, a cylinder, a iston moving in said cylinder, a reservoir a ove the cylinder having a port which communicates with the cylinder when the piston is retracted and at other times is closed by the piston.
2.. In combination with a liquid throwing piston, a cylinder, a piston moving in said cylinder, a spring pressing the piston in norosition, a reservoir extendi 0' longitudina y of and above the cylmder aving a port which communicates with the cylinder whenl the piston is retracted and at other times is closed by the piston.-
3. In combination with a liquid throwing arm, a cylinder, a piston having reciprocating movement in said cylinder, a reservoir above the cylinder having a port which communicates with the cylinder when the piston is retracted and at other times is closed by the piston, a spring pressing the iston in longitudinaloutward direction an a trigger to retract the spring and piston.
4. In combination in a liquid throwing arm, a cylinder, a piston moving in said cylinder, a reservoir above the cylinder having a port communicating with the cylinder when the piston is moved longitudinally backward and at other times is closed by the piston, a spring,.pressing the piston longitudinally outward and a trigger to retract the spring and piston, said trigger being hollow, andmeans to drain leakage around the piston into said hollow trigger.
' 5. In combination in a liquid throwing arm, a cylinder having an expanded middle portion, a piston moving in said cylinder said iston having an enlarged head, a sleeve ibosely enveloping the piston and attached to said head and making a close sliding fit in said enlarged portion of the cylinder, a reservoir above the cylinder having a port which communicates with the cylinder when the piston is retracted and at other times is closed y the piston, a spring pressing "the piston longitudinally in an outward direction, and a hollow trigger to retract the piston and spring said trigger being attached to said s p eeve enveloping the piston and said sleeve" having a hole for drainage into said hollow trigger.
6. In combination in a liquid throwing arm, a cylinder having an expanded middle portion, a piston moving in said cylinder said iston having an enlarged head, a sleeve lbosely enveloping the piston and attached to said head and making a close sliding fit in said enlarged portion ofthe cylinder, a reservoir above the cylinder having a port which communicates with the cylinder when the istolxll is retracted and at other time,1 is closed y t e iston, a s ring ressing t e iston longitudinally in arioutwiird direction ,La hollow trigger to retract the piston and spring said-trigger being attached to said sleeve enveloping the piston and said sleeve having a hole for drainage into said hollow trigger, and a removable closure for draining said hollow trigger.
witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 27th day of March, A4 I). one thousandninc hundred and nine.
