LIQUID-PISTOL.

Specification of Letters Patent.

Patented Sept. a, 1912.

To all whom it may concern:

Be it known that I, THOMAS RAYMOND ARDEN, a citizen of the United States of America, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Liquid-Pistols, of which the following is a specification.

The present invention relates to a toy l1quicf pistol of the type in which liquid is stored in the pistol, and quantities may be ejected therefrom at intervals, thus providing what may be termed a repeating pistol.

The principal object of the invention is to improve existing toys of this kind, by greatly reducing the number of parts used, thus minimizing the cost of production, and reducing the liability of the toy to become injured or to get out of order while in use.

The preferred embodiment of the invention is illustratively exemplified in the accompanying drawing, in which Figure 1 is a longitudinal central sectional view of the pistol; and

Fig. 2 is a transverse sectional View thereof on the line 22 of Fig. 1.

Referring to the drawing, the numeral 10 denotes the barrel and 11 the handle of the pistol. These parts are made up of like halves which are suitably secured together by any appropriate means.

i The forward end of the barrel is provided with an opening 12 through which liquid is drawn in and ejected, and the rear end of the barrel is provided with a cap 13 having a vent 14 at approximately itscentral portion.

Secured in the front end of the barrel is a liquid receiving cell 15 which is of any desired capacity, and is preferably made of a material which will not rust. The cell 15, which may be sweated or shrunk into the barrel 10, is open at one end and provided at its opposite end with a wall or head 16 having a constricted opening 17 therein.

Reciprocable within the cell 15 is a plunger which, in the instance shown, preferably consists of like rubber washers 18 arranged face to face and having laterally turned flanges 19 for contacting with the innerface of the cell 15.- Tig'htly seated against the outer face of each of the washers 18 is a metal disk 20, all of these parts of the plunger being firmly secured together in a man ner to be presently described.

Engaging the plunger for the purpose of reciprocating the same, and designed to keep the parts thereof closely united, is the head 21 of a rack bar 22 which extends rearwardly within the barrel 10. The rack bar is longitudinally slotted at 23, and passing through the slot 23 is a transverse pin 24 held rigid in the barrel 10.

The inner metal disk 20 is slit and formed up to provide two loops or eyes 25, each of which is adapted to engage one end of a coiled spring 26, the other end of which spring is held by an eye 27 at the rear of the barrel 10.

Pivotally mounted in the depending flanges 28 of the barrel, at a point intermediate the barrel 10 and the handle 11, is a rocking arm 29, the pivotal point of which is designated 30. This arm has a pawl 31 which is designed to engage the teeth formed at thelower edge of the rack bar 22, and is also provided with a finger piece 32 which projects upwardly through a slot 33 formed in the upper portion of the barrel 10.

The rear, lower, end of the rocking arm 29 is provided with an enlargement 34, and the pawl 31 of the arm 29 is normally held in engagement with the teeth of the rack bar 22 by means of a coiled spring 35, one end of which engages the enlarged portion of the rocking arm 29 and the other end of which is held by a hook 36 at the lower end of the handle 11, thereby holding the rocking arm 29 upwardly.

Mounted on the pivot 30 is a trigger 37 the upper arm of which has pivoted thereto at 38 a dog 39, one end of which is adapted to project into engagement with the teeth of the rack bar 22, and the other end of which dog is connected to a coiled spring 40. The spring 40, at the end opposite the connection to the dog, is held by a hook ll at the upper end of the handle 11.

For convenience of manufacture, and to impart the necessary strength and rigidity to the trigger 37, it is preferably made of a metal blank doubled upon itself, the rocking arm 29 and the dog 39 being pivotally supported between the walls of the trigger.

The rear end of the dog 39 rests on the enlargement 3d of the rocking arm, and the function of the spring 10 is to hold the forward end of the dog 39 in engagement with the teeth of the rack bar 22.

The operation of the device will be under stood from the following description. "As indicated in Fig. 1, the cell 15 is partly filled with liquid, and to eject this liquid, pressure is exerted against the trigger 37. As a result of such pressure, the trigger is rocked about its pivot 30 causing the dog-39 to advance the rack, thus depressing the pawl 31 whereby the latter falls in front of the next succeeding tooth. The rearward movement of trigger 37fis limited by the transverse stop pin 48. The effect ofthese several motionsis to move the rack bar forward in the barrel 10 the distance of one tooth of the'rack bar. The forward move ment of the rack bar resultsin the advance of the plunger in the cell 15 and the ejection of a fine stream of liquid throughqthe nozzle or constriction 1 7 in the head 16 of the cell. As long as, there is liquid in the cell '15, and the trigger 37 is pressed, the above described'sequence of steps willoccur.

Let it now be assumed that the cell 15 has been emptied of liquid, and it is desired to refill such cell. When the cell is empty,

the rack bar has practically reached the limit of its forward travel, and the plunger is in, the front end of the cell ,15. The

. mouth of the pistol is immersed in water,

and then the finger piece 32 is moved toward the mouth of the barrel 10, whereby the pawl 31 and dog 39 are moved out of engagement with the teeth of the rack bar. The springs 26 have a tendency to draw the plunger and rack bar backwardly in the barrel 10, and when the pawls 31 and 38 'ihave'been freed from the rack, as suggested, the'plunger will be retracted in the cell 15,

.'setting up a suction action therein and drawing "water into cell. 15 through the opening 16. When the cell isfilled, which is indicated'by the rear end of the rack bar 22 projecting slightly through opening 14,

I the curved surface 42 formedon the head ofthe rack bar will strike againstthepawl 31 and hold the same out of engagement with the rack bar. Then, to render the device operative to eject liquid, the finger biece 82 is moved rearwardl whereu on V 7 'the pawl 31 and dog 39 are againfbrought into engagement with the teeth of the rack bar, an'dthe trigger 37 may be operated.
