SWATTER GUN Filed April 28, 1958 7 lwue/wboz Jon E Kafiier.

Patented Dec. 20, 1938 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to improvements in swatter guns and seeks, among other objects, to provide a device of this character wherein two barrels are employed which barrels are disposed in over and under relationship so that the gun will be shorter, easier to handle, more attractive and more durable in use than other guns for the purpose.

A further object of the invention is to provide a swatter gun wherein improved trigger mechanism is employed.

And as a still further object, the invention seeks to provide a swatter gun employing cocking means which is characterized by the utmost simplicity and emciency.

Other and incidental objects of the invention will become apparent during the course of the following description.

My improved swatter gun is illustrated in the accompanying drawing, wherein:

Figure l is a longitudinal sectional view, partly in elevation, showing the construction of my improved swatter gun, the handle being shown in dotted lines in cocked position.

Figure 2 is a vertical sectional view on the line 2-2 of Figure 1, looking in the direction indicated by the arrows.

Figure 3 is an enlarged detail perspective view of a portion of the cooking mechanism.

' Figure 4 is an enlarged fragmentary horizontal sectional view on the line 4 l of Figure 1, looking in the directionindicated by the arrows.

Referring now more particularly to the accompanying drawing, the numerals I and 2 indicate the upper and lower barrels, respectively, of my improved swatter gun. The barrels I and 2 are preferably stamped in mating half sections from sheet metal and are connected to each other by ears 2a. A web 3 connects the upper and lower barrels. As will be seen in the drawing, the upper barrel I is considerably longer than the lower barrel 2 and said upper barrel is provided with an open outer end closed by a cap 4, which cap is adapted to be secured on the barrel by tongues tia bent to overlie the cap. The inner end of the barrel I merges into the breech of my improved gun, which breech is shown generally at 5. That is to say, the inner end of the barrel is closed by a downwardly inclined breech wall 6. The barrel 2 is closed at its outer end by means of an end wall 1 which limits the outward movement of a stop 8. Ears 8a serve to prevent separation of the half sections. The stop 8 is formed of rubber or other suitable material and is for the purpose of cushioning the outward stroke of the plunger which will be described hereinafter. It should be understood that the stop 8 may be dispensed with, if desired, in which event the plunger would be limited in its forward movement 'by the portion I. It should also be understood that the outer end of the barrel 2 may be completely closed.

The inner ends of the barrels 2 and 3 merge into enlarged portions 9 defining a trigger guard Ii), said trigger guard being a part of the breech 5. Formed on the breech 5 is a stock mounting portion I l adapted to have swingingly connected thereto a handle, shown generally at I2. The handle may be of the pistol grip variety or of any other suitable formation. There is slidably mounted in the barrel I a stem I3 which extends throughout the major portion of the length of the barrel and has fixed on its. inner end a head I 8. The outer end of the stem I3 has mounted thereon a striking cup I5 which preferably has a fiat outer face for engagement with an insect to be killed. Ribs I5a are mounted on the striking face of the cup. Coiled about the stem I3 within the barrel I is a relatively light spring I6. The spring is confined between the cap l and the head I4 so that, after the stem has been advanced in the barrel, the spring will serve to retract said stem to operative position with the head thereof near the breech portion 5. The head I4 is circular in formation and is adapted to slide freely within the barrel I throughout its length.

In the lower barrel 2 there is located the striking plunger I1. As best seen in Figures 1 and 3 of the drawing, the striking plunger I1 is formed with parallel spaced tines or body portions i8 and I 9 connected at corresponding ends by a vertically disposed striking member 20 which has its upper portion 2i extending through the reduced portion or web 3 to be disposed in the upper barrel I. The reduced portion or web 3 serves to guide the striking member 20 so that said member, as it travels within the barrels, will be prevented from shifting laterally out of position. The member 20 extends downwardly and 45 is formed at its lower end with a forwardly and downwardly inclined wall 22 terminating in a latch point 23. As best seen in Figure l of the drawing, the striking plunger I? has a relatively heavy spring'24 surrounding the tines I8 and i9 50 thereof. The spring 24 is limited against inward movement on the tines by means of inwardly struck portions 25 which are formed on the barrel 2 near its inner end. The spring is limited against outward displacement bymeans of ill an end disc 26 which is fitted on tongues 50 at the ends of the tines I8 and I9. By bending one of the tongues 50 in one direction and the other tongue 53 in the opposite direction, the disc is securely clamped in position. It will now be seen that the spring 24 is properly mounted on the plunger I1 and is confined between the stops 25 and disc 26.

In order to retract the plunger I'I within the breech 5, I provide a, cooking yoke, shown generally at 21. The cocking yoke is formed with a longitudinally extending slot 28 and a connecting portion 29 having trunnions 30 thereon. The connecting portion is adapted to be disposed within the upper forward end of the handle I2 with the trunnions 33 located in openings 3I in the handle, the handle being effectually mounted on the stock mounting portion II by means of a pin 32. The forward end of the cocking yoke 2'! is closed at 33 and, as best seen in Figure 3, the plunger I! is disposed in engagement with the cooking yoke 21 in such a manner that the portion 33 will be normally disposed against the striking member 23 between the tines I8 and I9. Swinging of the handle I2 to the position shown in dotted lines in Figure 4, will effect the retraction of the cooking yoke 21 and the plunger I'I within the barrels and breech of the gun and against the tension of the spring 24. As the striking member 20 is retracted, the stem I3 will be retracted in the barrel I by the spring It so that the head I4 will be in constant engagement with the upper portion 2I of the striking member 20.

Pivotally mounted within the breech is a trigger 34. The trigger 34 is preferably formed of light weight cast metal and is formed with .a finger engaging portion 35 extending into the trigger guard I5. The trigger 34 is also formed, forwardly of the finger engaging portion 35, with a spring engaging shoulder 36 and upwardly of said spring engaging portion and forwardly of said finger engaging portion, the trigger is formed with a keeper 3? which has a round upper end portion 38 defining a shoulder 39. The trigger 34 is pivotally mounted in the breech 5 by means of a pivot pin 49. Formed on the trigger 34 above the pivot 43 is a movement limiting portion 4I. As best seen in Figures 1 and 4 of the drawing, the portion II has its upper end slidably mounted between the walls of the reduced portion or Web 3 and said walls are provided with inwardly struck depressions 42 and 43 so that the portion 4! will be retarded in its movement to between the portions 42 and 43. In order to retain the trigger 34 in proper operative position with the finger engaging portion 35 extending within the guard I0, I provide a substantially U-shaped spring 44 which is pivotally mounted within the breech and has its free end engaging the shoulder 36.

It is thought that the operation of my invention will be clearly understood from the foregoing. However, a short discussion thereof is not thought to be out of order. It is first desirable to place the gun in cocked position ready for a fly swatting operation. This is done by swinging the handle I2 to the position shown in dotted lines in Figure 1, when the cooking yoke will be retracted for Withdrawing the plunger I1 and engaging the latch point 23 behind the shoulder 39 of the trigger 34. The inclined wall 22 cooperates with the round upper end portion 38 for permitting the striking member 20 to slide into operative position behind the keeper. The I handle I2 is then returned to operative position, as shown in full lines. It should be understood that the slot 28 receives therethrough the portion 4| of the trigger. The gun is now in cocked position. As heretofore stated, when the gun is in cocked position, the spring 24 will be under tension and the stem I3 will be in the full retracted position shown in dotted lines in Figure 1, with the head thereof in engagement with the portion 2I of the striking member 20. When the trigger is pulled, the spring 24, which, as stated, is relatively heavy, urges the stem I3 outwardly in the barrel for engaging the swatter disc thereon with an insect to be killed. Inasmuch as the spring I6 is relatively light, said spring will not offer a great deal of resistance to the outward movement of the stem. However, as soon as the insect has been killed and the gun is again cooked, the spring IE will have suflicient tension to retract the stem I3 to operative position for another insect killing operation. It is believed further description is unnecessary.

Having thus described the invention, what I claim is:
