:LIQUID PISTOL.
Application filed September 16, 1927, Serial No. 219,979, and in Gau'ada July 30, 1927.
The invention relates to improvements in liquid pistols and the object of the invention is to provide a trigger controlled pistol having a liquid storage chamber and a pump actuated by the trigger and adapted each time the trigger is pulled to discharge a liquid stream from the muzzle of the pistol such permitting many shots, so to speak, to be fired without requiring reloading. Y
A further object is to construct a pistol wherein the liquid will be expelled with considerable force. and to a considerable distance, and further to arrange the construction such that the storage chamber is formed as the stock or hand-grip of the pistol and is positioned such that it is within convenient range of the trigger.
A still further object of the invention is to construct the device in a simple, durable and inexpensivemanner and so that it can be readi-- 1y assembled, and also such that therewill be no possibility of leakage of the liquid when a the pistol is idle.
With the above more important objects in. view, the invention consists essentially 1n the arrangement and construction of parts as hereinafter more particularly described reference being had to the accompanying drawing, in which: a
Fig. 1 is a side view of the pistol.
Fig. 2 is afront end view of the pistol.
Fig. 3 is a vertical sectional view centrally and longitudinally through the pistol, certain parts being shown in side elevation.
Fig. 4 is a horizontal' sectional view at 4.-4 Fig. 2.
Fig. 5 is a perspective view of the trigger.
Fig. 6 is a perspective view of the upper bracket.
Fig. 7 is a perspective view of the lower bracket.
Fig. 8 is a perspective view of the upper end of the pump rod.
In the drawing like characters of reference indicate corresponding parts in the several figures.
The liquid pistol herein described is shaped ward end plate is supplied with an outlet hole or orifice 7. Further the upper side of the barrel is supplied with an inverted channellike extension 8, extending from front to rear and 'opening to the interior of-the barrel. It will be observed that the stock 2 is of considerable size and accordingly it will store a considerable quantity of liquid indicated at 9, the liquid being poured into the stock through the filling opening 10 which is closed by a screw plug 11, fitted with a ring 12, a rubber gasket 13-being inserted to ensure of a liquid tight joint.
The stock forms also a container for a pump indicated generally by a reference numeral 14, the pump being actuated by the In the present disclosure the pump is formed from the following parts:
An upper cylinder 15 is provided having the upper end permanently secured to the under side of the barrel and the lower end of r a frustoconical shape, forming a valve seat 16. On the upper cylinder we slidablymount a lower cylinder 17 similar to the upper cylinder and having a valve seat '15 formed at the lower end. Valves 19 and 20 in the form of balls are normally engaged with the seats. The valve 19 is held down byrthe action'of a coiled spring 21 engaging same. A spider 22' is inserted in the lower end of the cylinder 17 and overlies the ball 20 and a spring 22 engages the spider and operates to continuously press down the lower cylinder.
An' outlet or discharge pipe 23 is located within the barrel and connects the upper end of the cylinder 15 with the outlet orifice 7.
The trigger 4: is pivotally mounted on a cross 15in 2 1 carried by the barrel and it is forme to provide a conveniently shaped finger piece 25 and a pair of rearwardly extending spaced parallel arms 26 and 27, the arms having their rear extremities provided with opposing slightly inclined slots 28 and 29 situated more or less centrally over the upper end of the stock.
The upper end of the lower cylinder 17 is supplied with a lower bracket 30 which presents opposing lugs 31 and 32 and the lugs carry a cross pin 33, on which we mount pivotal y an eye 34 formed at the lower end of a vertical pump rod'35. The upper end of the sprin pump rod terminates in 'an eye'36 which receives a cross pin 37 the cross pin having the ends thereof slidably received within the slots 28 and 29.
An upper bracket 38 is secured permanently to the under side of the barrel within the stock and slidably receives the pump rod and a gasket 39 of rubber or such like resilient material is interposed between the bracket and the barrel. and slidably receives the pump rod and operates to effectively maintain a liquid tight joint between the stock and the barrel at the point where the pump rod passes through the barrel.
lVe alsomount a rubber or such like gasket 40 on the pump rod directly over the under side of the barrel and this also serves to maintain the liquid tight joint. 1
According to the above arrangement it will be seen that the upper spring 21 holds the ball 19 normally seated and the lower 22 operates to force down the lower cylin er and the pump rod so that the gasket 40 is held tightly pressed between the barrel and the rear ends of the arms 25 and 27. Further the spring 22 holds the finger piece of the trigger normally advanced.
Assuming that the stock is filled with aliquid and one pulls the trigger backwardly the liquid will be forcibly expelled by the pump through the outlet orifice? and each time the trig er is back-pulled a stream of liquid will discharge through the outlet opening. In this way it is possible to shoot the istol a great number of times as the stock olds a considerablequantity of liquid and the shoot ing can continue until the stock is virtually empty.
The inverted channel-sha ed extension of the barrel gives ample room or trigger movement and insures of a comparatively long stroke to the pump and of a considerable 1 stream being ejected from the pistol each time the trigger is pulled rearwardly.
We wish it to be particularly noted that with this type of pistol the stock forms not only a hand-grip convenient to the trigger but also provides aliquid stora e tank of considerable capacity and a cham er for receiving the pump. We wish it to be distinctly understood that the particular details of the pump might be materially changed without departing from the spirit of our invention provided the pump is contained in the stock which forms the liquid chamber and the trigger operates to actuate the pump when pulled towards the stock.
What we claim as our invention is:
1. A liquid pistol comprising a horizontally disposed barrel, a hollow stock extendper cylinder to the orward end of the barrel, I
and a pump rod operatively connecting the trigger with the lower cylinder and adapted in the rear pulling of the trigger towards the stock to raise the lower cylinder.
2. A liquid pistol comprising a horizontally disposed barrel, a hollow stock extending downwardly from the barrel and forming a liquid storage compartment, a trigger pivotally carried by the barrel and presenting a finger piece adjacent to and in advance of the stock, a pump contained within the stock and embodying a stationary cylinder and a movable cylinder slidably carried by the stationary cylinder, said cylinders having their lower ends presenting valve seats receiving spring pressed valves, a discharge pipe leading from the upper end of thestationary cylinder to the forward end of the barrel and an operatin connection between the trigger and the mova 1e cylinder and adapted in the rear pullin of the trigger towards the stock to raise t e movable cylinder.
3. A liquid pistol comprising a horizontallydisposed barrel, a hollow stock extending downwardly from the barrel and form- .ing a liquid storage compartment, a trigger pivotally mounted within the barrel and presenting a rearwardly extendin arm overlying the stock anda downwar 1y extending finger piece passing through a suitable slot provided in the barrel and positioned in advance of the stock, an upstanding upper stationary cylinder secured to the barrel, a lower gylinder slidably carried by the upper cyliner, said cylinders having their lower ends presenting valve seats receiving spring pressed valves, a discharge pipe leading from the upper end of the stationary cylinder through the barrel to the-forward end thereof and a pump rod operatively connecting the trigger arm with the lower cylinder and adapted in the rear pulling of the trigger to wards the stock to raise thelower cylinder.
