SWATTER GUN Filed May l0, 1939 Patented Sept. 3, 1940 y UNITED STATES man@ PATENT OFFICE 2 Claims.

My invention relates to improvements in swatter guns.

Among the objects of my invention is to provide a swatter gun wherein improved trigger mechanism is employed and wherein improved and simpliiied cocking mechanism is provided,

and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing a preferred form of my invention, yetl I desire it understood that the same is susceptible of modification and change without departing from the spirit of my invention.

Referring to the drawing Fig. l is a side elevavation of my swatter gun; Fig. 2 is a sectional view with the gun in cocked position; Fig. 3 is a sectional view of the same in red position; Fig. 4 is a detail sectional view on line 5 5 of Fig. 1, and Fig. 5 is a detail sectional view on line 5-5 of Fig. 1.

The embodiment selected to illustrate my invention comprises upper and lower barrels l and 2. The barrels I and 2 together with the web 3, breech 30 and handle 3| are preferably stamped in mating half sections from sheet metal. A web 3 connects the upper and lower barrels. The upper barrel l is considerably longer than the lower barrel 2 and said upper barrel is provided with an open outer end which is partially closed by a cap d that is adapted 4to be secured on the barrel by tongues 5 bent to loverlie the cap.

'Ihe inner end of barrel l merges intoI the breech of my gun, which breech is shown generally as 30. The lower barrel 2 is closed at its outer end by means of an end wall 32 and at its inner end by means of end wall 33.

A bumper or stop member 34 is preferably composed of rubber and is placed at the outer end of low-er barrel 2. pensed with, if desired. Within lower barrel 2 is placed my firing mechanism 35. It comprises an elongated body member 36, a round outer end 3l and an inner end comprising downwardly eX- tending portion 38, engaging notch 39, and upper portion 52 which extends upwardly into the upper barrel l and holds circular stop member All in barrel i. Surrounding body member 36 of my ring mechanism 35 is a relatively heavy round spring member ill. This spring member 4| is held on body member 36 by round outer end 31 and at its inner end by upper portion 52 and downwardly extending portion 38 of my firing mechanism 35.

Stop member 34 may be dis- (ci. inl-sr) y Spring member'dl surrounds body member 36 and fits within lower barrel 2 so as to engage at its inner end Wall 33. While wall 33 acts as a vstop for spring 4l yet it does not permit the backward movement of firing mechanism 35. The web 3 holds upper portion 52 of ring mechanism 35 in position during movement.

There is slidably mounted in the upper barrel l a stem lil which terminates at its inner end at end 132 which is larger in circumference than the body portion of stem lll. Said inner end l2 is adapted to come in Contact with circular stop member 53 of my iiring'mechanism 35. The outer end of my stem lil has mounted thereon a striking member i3 which preferably has an outer face for engagement with an insect to be killed. Knobs ll are preferably mounted on the striking face of the cup, but they may be eliminated if desired.

Coiled about the stem lll, which extends throughout most of the length of upper barrel I, is a relatively light spring 55. This spring `45 is conned between cap 4 which partially closes barrel l and inner end 42 of stem Iii. It should be understood that stem l0 extends from barrel i through the open portion of cap 4 and terminates outside barrel l in striking member 43.

Inclosed within breech 3@ and handle 3lr is a release member 45. Release member 46 is attached at its upper end to breech 30. At its lowerl end it engages one `end of spring 41, which spring 4l is attached at its other end to another portion of breech 30'. Release member 46 is provided with a bent upl portion F68 which is adapted` to engage the engaging notch 39 of my ring mechanism 35. Spring 5l serves the function ofr keeping bent up portion 48 of release member t5 in a'position directly behind barrel 2 so that it may engage engaging notch 39 of firing mechanism 35. Spring il permits release member 46 to move downwardly when it i-lrst engages the engaging notch 39 and then causes it tomove upwardly into the engaging notch 39 and normally remain in engagement therewith. Spring dl permits release member 45 and thus bent up portion 48 to Amove downwardly when a backward force is exerted on it by the backward movement of trigger member 53. Release member 45 thus is lowered out of the notch 39 and permits the' forward movement of ring mechanism 35. Spring lil then causes release member i3 to again move upwardly so as to be in a posi' tion to engage the engaging notch 39 of firing mechanism 35.

A trigger member 53 comprises an elongated body member 49 and a finger portion 50. Body member 49 is preferably bent back upon itself at point 5I and contacts release member 45. Body member 49 may merely terminate at point 5I rather than be bent back as is shown in the drawing.

In operation my swatter gun is cocked by pushing striking member 43 and thus forcing stem i l back within barrel l. When the inner end 42 of stem l comes into contact with stop member 40 of ring mechanism 35, it forces the entire firing mechanism 35 backward within the gun. Since spring member 4i is held within barrel 2 the backward movement of the firing mechanism causes the spring to contract and develop greater tension.

The backward movement is continued until the engaging notch 39 of ring mechanism 35 comes into engagement with bent up portion 48 of my release member 4S. These parts are so constructed that they will remain engaged until disturbed by movement of release member 46. My swatter gun is now cocked and ready to iire.

Firing is accomplished by a backward movement of finger portion 5D of trigger member 53. The backward movement of finger portion 50 causes the elongated body member 49 to move backward and thus causes the end 5! of trigger member 53 to exert rearward pressure on release member 46. Release member 46 is adapted to move downwardly within handle 3l when such pressure is applied. This downward movement of release member 46 causes bent up portion 48 of release member 46 to also move downwardly and thus come out of engagement with engaging notch 39 of ring mechanism 35.

The tension which has been created in the relatively heavy spring 4i which is inclosed in lower barrel 2, surrounding the body portion of firing mechanism 35, causes the entire firing mechanism 35 to move rapidly forward. The rapid forward movement causes stem l0, which is enclosed within barrel I, to be moved rapidly forward due to the rapid forward movement of circular stop member 49 of ring mechanism 35 which has been in contact with inner end 42 of stem I0.

The forward movement of stem l0 thus causes striking member 43 to move rapidly forward and strike the insect to be killed. Stem IB is prevented from leaving barrel Il by end 42 which is larger than the opening in the cap which partially closes barrel l. The light springl 45 which surrounds stem I0 serve the double function of maintaining end 42 of stem I0 in engagement with circular stop member 40 of firing mechanism 35 both when my swatter gun is cocked and after it has been fired, prior to cooking.

Having thus described my invention I claim:

1. In a swatter gun an upper barrel, a lower barrel, a breech connecting the inner ends of the barrels, a stem slidable in the upper barrel, a firing member having a body portion with a rounded front end and a hook at the rear end, a resilient member surrounding said body portion and extending from the rounded front end to the hook at the rear end thereof, said ring member also having a rearward extension with a stem contacting portion and an engaging notch, a trgger member, a release member attached to the breech and having a bent up portion and a spring, said bent up portion engaging the engaging notch of the firing member for holding the firing member in cocked position, said trigger member upon backward movement exerting pressure on the bent up portion, said spring permitting the bent up portion to move downwardly and away from engagement with the engaging notch and permit the ring member to advance the stem.

2. In a swatter gun an upper barrel, a lower barrel, a breech connecting the inner ends of the barrels, a stem slidable in the upper barrel, a ring member having a body portion with a rounded front end and a hook at the rear end, a resilient member surrounding said body portion and extending from the rounded front end to the hook at the rear end thereof, said firing member also having a rearward extension with an upper stem contacting portion and a lower engaging notch, a trigger member, a release member attached at one end to the breech and having a projection adapted to engage the engaging notch of the firing member for holding the ring member in cocked position, a spring attached at one end to the breech and at the other end to the other end of said release member, said trigger member upon backward movement exerting pressure on the release member, said spring holding the release member in engagement with the firing member and permitting the release member to move downward and disengage from the engaging notch of the firing member to permit said ring member to advance the stem, said spring then exerting pressure to return the release member and trigger to their normal position.
