Aug. 3, 1965 1.. SCHROEDER FLY SWATTING GUN Filed March 5. 1964 INVENTOR. [flu/IL ff/Kat'ozg BY Ma,

United States Patent 3,197,917 FLY SWATTING GUN Louis L. Schroeder, 7517 Kenwood Ave, Wauwatosa, Wis. Filed Mar. 5, 1964, Ser. No. 349,683 12 Claims. (Cl. 43-135) This invention relates to a fly swatting gun.

The gun functions by means of a swatting vane similar to that of a conventional swatter but different in being movably instead of rigidly jointed to its arm. This vane, unlike its counterpart, which is usually swung in a kind of arc, is caused to approach its target in a straight line like an arrow, serving its swatting purpose at the end of forward travel by forceful rotation on its own axis at its joint with the arm (hereinafter called slide).

In the basic constructive elements a pistol grip handle provides ways for a slide which, in the preferred embodiment shown, is skeletonized, being made up of parallel wires connected near their respective ends. A trigger mounted on the handle releasably engages the slide near is forward end to hold it in retracted position. Rubber bands constitute a preferred form of springs means for urging the slide forwardly, anchorages being provided for the bands on the handle and slide. At the forward end of the slide is a swatting vane, preferably both flexible and foraminous. The base or shank of this vane is pivoted to the slide for rotation upon a transverse axis, and has the forward end of a flexible cord-like tension element wrapped pulley-like around its axis and secured to bias the vane for rotation. The tension element extends rearward through bearing openings in the handle and supports a cushion stop just ahead of its anchorage at the rear end of the slide.

1 The functioning of the gun upon trigger release results from the biasing influence of. the tension element upon the swatting Vane during only the latter part of the shooting cycle. Initially, when the slide is in its retracted position, that is, cocked, the total length of the tension element between its terminations is such that it will permit the vane to be folded or disposed rearward into an unbiased reclining position overlying both slide and handle. Thus, in the forward travel of the vane toward its target, the relatively narrow shank is leading the more fanned-out portion. This minimizes the retarding effect of air friction.

The point at which the biasing effect of the tension element takes place during the shooting cycle is determined by the location of the cushion stop fixed to the rearward of the tension element somewhat ahead of its anchorage. The location is such that, upon triggering, when the slide, tension element and yet unbiased vane move forward from the retracted position, this stop moving forward also will impinge at an optimum point toward the end of slide travel on a surface at the rear of the handle and thus be brought to an abrupt halt. The continuing forward movement of the slide itself will from now on set up a tautness and strain in the tension element between the stop and the swatting vane ahead. This tautness, by means of the pulley-like wrapping of the tension element around the shank of the vane, tends to rotate it about it trans-' verse axis.

In operation, then, the vane first moves straight forward, then rises and moves circularly until stopped by an object or surface (or, swinging around almost full circle, by meeting the underside of the slide).

In the drawings:

FIG. 1 is a plan view of the device as it appears with the slide cocked and the vane flat, part of the swattingvane being broken away.

FIG. 2 is a view in side elevation of the device as shown in FIG. 1.

FIG. 3 is a View in side elevation fragmentarily illustrating the slide in its advanced position with the vane erected for action upon a vertical surface such as the wall fragmentarily illustrated in diagrammatic form.

FIG. 4 is a view taken in section on the line 4-4 of FIG. 1.

FIG. 5 is a view in perspective fragmentarily illustrating in relatively separated positions blocks used at the rear of the slide as an anchorage for the elastic band spring.

The trigger grip handle it) has on its upper side spaced bosses 12 and 1 which provide bearings or ways in which are reciprocable the wires 16 and 1.3 which constitute the side portions of a slide generically designated by reference character 20. At their rear ends the wires are connected by a transverse member 22 which is best shown in FIG. 5 and includes a rearwardly open channel 24 for reasons hereinafter explained. At a point spaced somewhat from the forward ends of the

wires

16 and 18 there is a cross member 26 which connects and spaces the wires and has a downwardly and forwardly projecting flange at 28 which can be engaged by the hooked end 3% of the trigger detent 32 to hold the slide cocked. This detent is pivoted at 34 to the handle grip and is subject to clockwise bias about the pintle 34 as viewed in FIGS. 2 and 3. The bias is provided by a length of clock spring 36 which is attached to the finger piece 33 of the trigger. The bias of the trigger tends to engage its hooked end 30 with the flange 2-8 of the slide to hold the slide in its rearmost or cocked position, in which it is illustrated in FIG. 2.

Beyond the cross member 26, the

wire side members

16 and 18 of slide 26) have inwardly turned ends 17 and 19 as best shown in PEG. 1 to engage the opening an in the mounting portion 42 of the fly swatting vane 44. This vane may be made in any appropriate manner. It is preferably foraminous, being provided with openings 46 which readily pass air but are insuificiently large to permit a fly or other insect to escape the impact of the vane. The vane is also desirably flexible and in practice may conveniently be made of thin rubber or flexible synthetic resin and connected by molding or otherwise to the mounting 42.

The entire slide, and the vane 44 pivotally mounted at the end thereof, is biased from right to left as viewed in FIGS. 1, 2 and 3. In lieu of wire springs for this purpose, it is preferred to use elastic bands 48 and 5th for which laterally projecting anchorages 52 and 54 are provided on the boss 12 of the pistol grip handle 14). Conventional rubber bands are appropriate. Other bosses 56 and 58 project laterally from the rear end of the slide 20. See FIG. 5. These may conveniently be formed on separately fabricated blocks lid and 62 pushed onto the straight rear ends 57 of

wires

16 and 18 extending slightly beyond cross member 22 and seated in channel 24. These blocks are held frictionally and have holes at 59 into which the rear ends 5] of

wires

16 and 18 are received to pin the respective blocks in the channel 24 of cross member 22.

The blocks have complementary beveled surfaces at 64 and 66. Together these surfaces provide a notch 68 for the end of a tension element 70 which triggers the erection of the vane. Element 70 is preferably knotted as shown at 72. for anchorage in the notch. All four bosses 5'2, 54, 56, 58 preferably include holes through which the rubber bands are threaded and looped to trap them. (See holes 7 1 in FIG. 5.) Splitting the rear anchorage into two parts facilitates fastening of the bands.

ment 7% extends through openings in the two bosses 12 and 14, one such opening being shown at 78 in FIG. 4. The tension element passes over the cross member 26 near the front end of the slide and then extends downwardly beneath the mounting member 42 of vane 44, the lower end of mounting member 42 preferably being rounded as shown at Sh so that it acts like a segment of a pulley. The end portion 82 of the tension element extends through the mounting member 42 and is anchored by a knot. The tension element may very well comprise a thread or cord, a length of fish line made of synthetic resin being ideal for the purpose.

The length of the tension element 753 in relation to the length of the rubber band springs 48 and St) is such that, in the position of the parts shown in FIG. 3, the springs 4-8 and 5d are almost relieved of bias whereas the tension element 7% is taut and. maintained under tension by the residual bias of the springs. On the other hand, when the slide is pushed to the rear and cocked, as shown in FIG. 1 and FIG. 2, the tension member is substantially free of bias and the swatting vane 44 can readily be folded to overlie the handle as shown.

In use, the operator uses the handle to hold the cocked device at a point spaced from the intended victim by a distance approximating the length of movement of the slide. In PEG. 3 a wall is fragmentarily illustrated at $6 and it may be assumed that there is an insect on the wall which is to be exterminated. If the insect were on a table or the like, the operation'would be the same except that the vane would rotate another 90 to extend horizontally as shown on the left in FIG. 2.

With the device held as described, the operator uses finger pressure on the part 38 to release the tri er, whereupon the springs 43 and 5d project the slide rapidly forwardly. There is a very great advantage in having the vane horizontal at this time, since it then offers relatively 'little resistance to the forward movement of the slide. In fact, such air pressure .as it encounters during the rapid forward movement of the slide tends to hold the vane in its streamlined horizontal position as illustrated in FIGS. 1 and 2.

When the elastic bumper cushion '74 encounters boss 14, however, the tension element 70 is immediately brought to rest. During such residual slide movement as is possible, the tension element rotates the mounting member 4-2 of the swatting vane 44 to erect the vane, causing it to move toward and beyond an upright position. If the device has been properly spaced from the wall, the vane will encounter the wall with considerable impact and normally will tend to flex as shown inFIG. 3. Upon being removed from the wall, the vane 44- will continue to be pulled downwardly by the tension member until the vane hangs beneath the slide. As soon as the slide is again cocked in the position shown in FIGS. 1 and 2, the vane is readily swung, without resistance, to the streamlined position in which it is shown in these views.
