The objects described above can be solved by a compact bug killing gun according to the features of claims 1 - (1) The compact bug killing gun providing the desired features may be constructed from the following components. A compressed gas source is provided. A chamber is provided. The chamber is fluidly connected to the compressed gas source. A barrel is provided. The barrel is located at a distal end of the chamber. A compressed gas release mechanism is provided. The release mechanism is connected to the compressed gas source. A projectile storage magazine is provided. The magazine stores particulate projectiles and is located adjacent the chamber.
The projectile storage magazine includes a cylindrical chamber. The cylindrical chamber has first side and second side projectile loading slots. The loading slots extend from an upper edge of the cylindrical chamber to a base of the cylindrical chamber. The cylindrical chamber has a circular opening at a lower end. The lower end is fitted sealably to an upper end of a vertical circular opening which extends vertically through the chamber. A rectangular projectile feeding tray is provided. The feeding tray surrounds the cylindrical chamber and provides additional space for particulate projectiles outside of the cylindrical chamber. A hingedly attached sealing lid is provided. The sealing lid has first and second semi-circular ridges on an underside of the lid. The ridges are designed to surround upper edges of the cylindrical chamber adjacent the first side and second side projectile loading slots. The sealing lid has a peripheral channel on the underside. The peripheral channel is sized, shaped and located to seal the rectangular projectile feeding tray when the sealing lid is moved to a closed position. A lid latching mechanism is provided. The lid latching mechanism is located opposite a hinge for the sealing lid.
A projectile loading mechanism is provided. The loading mechanism moves the particulate projectiles into the chamber from the magazine. A cocking mechanism is mechanically connected to the compressed gas source, the compressed gas release mechanism, and the projectile loading mechanism. An automatic cocking status indicator is provided. The cocking status indicator moves to a raised, visible position after cocking of the gun and moves to a lowered, hidden position after discharge of the gun. An external, manual safety mechanism is provided. The manual safety mechanism is movable from a safe position to a firing position by a user while maintaining a grip on the gun. A stock is provided. The stock houses and supports the compressed gas source, the compressed gas release mechanism, the barrel, the chamber, the projectile storage magazine, the cocking mechanism and the projectile loading mechanism. When the gun is cocked by the cocking mechanism, the projectile loading mechanism gathers a predetermined quantity of the particulate projectiles and positions the projectiles in the chamber. When the compressed gas release mechanism is activated the projectiles are ejected from the chamber into the barrel and expelled from the gun. - (2)_In a variant according to the features of claim 2, the compressed gas source is selected from the group that includes a prefilled CO2 cartridge, a refillable compressed gas cylinder, a pneumatically pumped gas reservoir, a spring-activated compressed gas system and an external compressed gas line.
- (3) In another variant according to the features of claim 3, the spring-activated compressed gas system further includes a cylinder. The cylinder has a front end and a rear end and is fluidly connected to the chamber at the front end. A piston is provided. The piston fits sealably in the cylinder and is located within it. A compression spring is provided. The compression spring urges the piston toward the front end. A spring compression mechanism is provided. The compression mechanism urges the piston towards the rear end and compresses the compression spring. A latching mechanism is provided. The latching mechanism releasably retains the piston adjacent the rear end and retains the compression spring in a compressed state. A user performs the gun cocking action, the spring compression mechanism is operated, the piston is urged toward the rear end of the cylinder, the spring is compressed and the spring and the piston are retained by the latching mechanism until released, allowing the piston to move rapidly toward the front end of the cylinder. This provides a burst of compressed gas in the cylinder and to the connected chamber.
- (4) In still another variant according to the features of claim 4, the compressed gas release mechanism further includes a trigger. The trigger is rotatably mounted to the stock and urged in a counter-clockwise direction by a curved trigger return spring. The trigger return spring is constrained by a curved channel in the stock. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents release of the latching mechanism unless the cocking action is completed. The trigger has an elevating ramp located rewardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is pivoted rearwardly. The releasing bracket is pivotably mounted to the stock and has an upward pointing travel limiting arm located within a notch in the stock. The releasing bracket has a downwardly facing rib. The rib releasably engages an upwardly facing control notch in a main pole of the latching mechanism.
The main pole is attached to the piston, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch. The main pole moves rearwardly in a channel in the stock during the cocking action. The releasing bracket retains the main pole in a first, cocked position as the rib engages the control notch. The bracket releases the main pole to a second, fired position as the trigger is pivoted rearwardly, elevating the releasing bracket and raising the rib from the control notch. This allows the main pole and the piston to move forward as urged by the compression spring, pressurizing the cylinder. - (5) In a further variant, the lower end of the container is fitted sealably to the upper end of said vertical circular opening through the chamber with a sealing washer.
- (6) In still a further variant according to the features of claim 5, the projectile loading mechanism further includes a metering rod. The metering rod is sized and shaped to fit sealably through the vertical circular opening through the chamber and has an orthogonal activation bar extending from its lower end and a through hole located above the activation bar. The through hole is orthogonal to the bar and the metering rod and sized and located to align with the chamber when the bar is positioned against a stopping surface. The activation bar is urged upwardly by a return compression spring to rest against the lower end of the vertical circular opening in the chamber.
The through hole fills with the particulate projectiles when located above the chamber in the cylindrical chamber during the cocking action. The activation bar is urged downwardly by a pivotally mounted subordination pole to rest against the stopping surface just after activation of the compressed gas release mechanism. This permits the compressed gas to eject the particulate projectiles from the chamber and through the barrel. - (7) In yet a further variant of the invention according to the features of claim 6, the projectile loading mechanism further includes a mid-chamber pipe. The pipe extends downwardly from a lower end of the cylindrical chamber. A lower portion of the pipe provides a stop for one end of a return compression spring. A trajectory guide is provided. The guide is located below the lower end of the cylindrical chamber, has a hollow bore sized to fit slidably about the pipe and has a vertical slot that extends downwardly from the lower end for a first predetermined distance. The slot terminates in a stopping surface. The trajectory guide is located about the pipe and provides a support platform for attachment of the projectile storage magazine. A metering rod is provided. The rod is cylindrical in shape and is sized to fit slidably within the pipe and has an orthogonal activation bar extending from its lower end. The metering rod has a through hole located above the activation bar. The through hole is orthogonal to the bar and the metering rod and is sized and located to align with the chamber when the bar is positioned against the stopping surface. The return compression spring urges the metering rod upwardly to rest against the lower end of the vertical circular opening in the chamber. A subordination pole is provided. The pole has a first end and a second end and is pivotally mounted to a cover for the compressed gas source. The first end of the subordination pole includes a metering slot. The metering slot surrounds the activation bar. The second end of the subordination pole is urged upwardly by a cam during forward movement of the cocking mechanism. Upward movement of the second end of the subordination pole moves the activation bar downwardly, compresses the return compression spring and aligns the through hole of the metering rod with the chamber. This permits the compressed gas to drive the particulate projectiles out of the chamber and through the barrel. Downward movement of the second end of the subordination pole causes the activation bar to move upwardly as urged by the return compression spring. This allows the particulate projectiles to fill the through hole of the metering rod as it moves in the projectile storage magazine surrounded by the particulate projectiles.
- (8) In another variant according to the features of claim 7, the spring compression mechanism further includes a primary gear rack. The gear rack is slidably located in a channel in the stock, has gear teeth located upon an upper surface and has mounting fixtures adjacent a forward end for attachment of a slide handle. A reduction gear drive is provided. The gear drive is mounted to an outer cover of the cylinder. A secondary gear rack is provided. The secondary rack is attached below the piston and is located above the reduction gear drive. The primary gear rack engages the reduction gear drive and the reduction gear drive engaging the secondary gear rack. Rearward movement of the slide handle moves the primary gear rack rearward, rotates the reduction gear drive and moves the piston rearward, compressing the compression spring.
- (9) In still another variant according to the features of claim 8, a downward pointing cam lobe is provided. The cam lobe is located beneath and orthogonal to the metering slot. A cam activating tab is provided. The tab is located adjacent to a side edge and front end of an upper surface of the primary gear rack. The activating tab has a contoured inner surface. The contoured inner surface is sized, shaped and located to engage a front edge of the cam lobe as the primary gear rack is moved rearwardly and forwardly during operation of the cocking mechanism. Engagement of the cam lobe causes upward movement of the metering rod followed by downward movement of the metering rod during operation of the cocking mechanism. Such movement serving to dislodge any particulate projectiles adhering to the metering rod.
- (10) In a further variant according to the features of claim 9, engagement of the cam lobe by the cam activating tab during forward movement of the primary gear rack during operation of the cocking mechanism provides an auditory confirmation of completion of the operation.
- (11) In still a further variant according to the features of
claim 10, a control slot, moving in concert with main pole, maintains a first end of an internal safety pivot in an elevated position during rearward movement of the control slot. This causes a second end of the pivot, to engage an upper protrusion at an upper end of a trigger of the compressed gas release mechanism, thereby preventing activation of the mechanism. The control slot causes downward movement of the first end of the internal safety pivot to a lowered position upon completion of forward movement of the primary gear rack and the control slot. The downward movement permits release of the upper protrusion of the trigger and permits activation of the gas release mechanism. - (12) In yet a further variant according to the features of claim 11, the support stock further includes a sight glass. The sight glass is positioned adjacent the magazine and permits a view of a level of the particulate projectiles contained in the magazine.
- (13) In still a further variant according to to the features of claim 12, a cocking mechanism control is provided. The cocking mechanism control comprises a receiving notch. The receiving notch is located in an outer side rail of the cocking mechanism. A blocking portion is provided. The blocking portion is pivotally mounted to an underside of the secondary gear rack. The blocking portion is urged toward the receiving notch by a spring. The blocking portion has a retaining protrusion at a lower edge. The retaining protrusion is sized and shaped to engage the receiving notch and has an angled surface extending upwardly above said retaining protrusion. An activating portion is provided. The activating portion is attached to the subordination pole adjacent the first end. The activating portion moves downwardly with the subordination pole upon activation of the compressed gas release mechanism. The activating portion bears on the angled surface of the blocking portion and urges the retaining protrusion out of the receiving notch, thereby permitting the cocking mechanism to be activated.
- (14) In another variant, the gun uses a prefilled CO2 cartridge as a compressed gas source and the gun further includes a cylindrical cartridge chamber. The cartridge chamber is sized and shaped to enclose a CO2 cartridge and has a sealable opening at a first end for introduction of the cartridge. A concave seat located at a second end is provided. The seat is sized and shaped to fit sealably about a discharging end of the cartridge. A hollow puncturing needle is located within the seat. A sealing cap is provided. The cap is removably attached to the cartridge chamber by mating screw threads. Tightening of the cap urges the cartridge against the puncturing needle. A pressure vessel is provided. The pressure vessel is fluidly connected to a metering device. The metering device permits a predetermined charge of compressed gas to enter the chamber upon activation of the compressed gas release mechanism.
- (15) In still another variant, the compressed gas release mechanism further includes a trigger. The trigger is rotatably mounted to the stock and urged in a counter-clockwise direction by a curved trigger return spring. The trigger return spring is constrained by a curved channel in the stock. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents release of the latching mechanism unless the cocking action is completed. The trigger has an elevating ramp located rewardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is pivoted rearwardly. The releasing bracket pivots on a fitting attached to the stock, has an upward pointing travel limiting arm located within a notch in the stock and has a downwardly facing rib. The rib releasably engages an upwardly facing control notch in a loading rod. The loading rod is urged forward by a loading coil spring, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch.
The loading rod moves rearwardly in a channel in the stock during the cocking action. The releasing bracket retains the loading rod in a first, cocked position as the rib engages the control notch. The releasing bracket releases the loading rod to a second, fired position as the trigger is moved rearwardly, elevating the releasing bracket and raising the rib from the control notch. This allows the loading rod to move forward as urged by the loading coil spring. The loading rod activates the projectile loading mechanism and the metering device. - (16) In yet another variant of the invention, the gun uses a pneumatically pumped air reservoir as a compressed gas source and the gun further includes a gas cylinder. The cylinder has an inlet valve and an outlet valve. A piston is provided. The piston fits sealably within the cylinder. A pumping mechanism is provided. The pumping mechanism is mechanically linked to the piston and moves the piston from an extended position to a compressed position within the cylinder. The inlet valve is in an open position as the piston moves from the compressed position to the extended position and is in a closed position as the piston moves from the extended position to the compressed position. The outlet valve is in a closed position as the piston moves from the compressed position to the extended position and is in an open position as the piston moves from the extended position to the compressed position.
The air reservoir is fluidly connected to the outlet valve and the chamber. The projectile loading mechanism permits a predetermined charge of compressed gas to enter the chamber upon activation of the compressed gas release mechanism. Repeated movement of the piston by the pumping mechanism from the extended position to the compressed position within the cylinder will increase pressure within the air reservoir, permitting the particulate projectiles to be ejected from the chamber with increased force upon release of the pressure by the compressed gas release mechanism. - (17) In a further variant, the compressed gas release mechanism further includes a trigger. The trigger is rotatably mounted to the stock and urged in a counter-clockwise direction by a curved trigger return spring. The trigger return spring is constrained by a curved channel in the stock. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents release of the latching mechanism unless the cocking action is completed. The trigger has an elevating ramp located rewardly of the upper protrusion.

- (19) In yet a further variant, the compressed gas release mechanism further includes a trigger. The trigger is rotatably mounted to the stock and urged in a counter-clockwise direction by a curved trigger return spring. The trigger return spring is constrained by a curved channel in the stock. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents release of the latching mechanism unless the cocking action is completed. The trigger has an elevating ramp located rewardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is pivoted rearwardly. The releasing bracket pivots on a fitting attached to the stock, has an upward pointing travel limiting arm located within a notch in the stock and has a downwardly facing rib. The rib releasably engages an upwardly facing control notch in a loading rod. The loading rod is urged forward by a loading coil spring, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch.
The loading rod moves rearwardly in a channel in the stock during the cocking action. The releasing bracket retains the loading rod in a first, cocked position as the rib engages the control notch. The releasing bracket releases the loading rod to a second, fired position as the trigger is moved rearwardly, elevating the releasing bracket and raising the rib from the control notch. This allows the loading rod to move forward as urged by the loading coil spring. The loading rod activates the projectile loading mechanism and the metering device. - (20) In another variant, the gun uses an external compressed gas line as a compressed gas source and the gun further includes an external compressed gas line. The line is connected to a compressed gas source and has a shut off valve and an attachment fitting located adjacent a first end. A mating attachment fitting is provided. The mating fitting is mounted to the support stock and is fluidly connected to a metering device. The metering device is fluidly connected to the chamber. The metering device permits a predetermined charge of compressed gas to enter the chamber upon activation of the compressed gas release mechanism. The external compressed gas line is attached to the mating attachment fitting, the shut off valve is opened and the compressed gas is released by the metering device upon activation of the compressed gas release mechanism.
- (21) In still another variant, the compressed gas release mechanism further includes a trigger. The trigger is rotatably mounted to the stock and urged in a counter-clockwise direction by a curved trigger return spring. The trigger return spring is constrained by a curved channel in the stock. The trigger has an upper protrusion. The upper protrusion engages an internal safety pivot. The safety pivot prevents release of the latching mechanism unless the cocking action is completed. The trigger has an elevating ramp located rewardly of the upper protrusion. The elevating ramp urges a releasing bracket of the latching mechanism upwardly against a downwardly urging compression spring as the trigger is pivoted rearwardly. The releasing bracket pivots on a fitting attached to the stock, has an upward pointing travel limiting arm located within a notch in the stock and has a downwardly facing rib. The rib releasably engages an upwardly facing control notch in a loading rod. The loading rod is urged forward by a loading coil spring, has an upwardly angled ramp at a rear end, located behind the control notch. The ramp guides the rib into the control notch.
The loading rod moves rearwardly in a channel in the stock during the cocking action. The releasing bracket retains the loading rod in a first, cocked position as the rib engages the control notch. The releasing bracket releases the loading rod to a second, fired position as the trigger is moved rearwardly, elevating the releasing bracket and raising the rib from the control notch. This allows the loading rod to move forward as urged by the loading coil spring. The loading rod activates the projectile loading mechanism and the metering device. - (22) In yet another variant of the invention, a pistol grip and a forearm of the support stock have flattened lower surfaces.

The throughhole 246 is orthogonal to thebar 238 and themetering rod 234 and sized and located to align with thechamber 18 when thebar 238 is positioned against the stoppingsurface 250. Areturn compression spring 254 urges themetering rod 234 upwardly to rest against alower end 258 of the verticalcircular opening 68 in thechamber 18. Asubordination pole 262 is provided. Thepole 262 has afirst end 314 and asecond end 318 and is pivotally mounted to acover 322 for the compressedgas source 14. Thefirst end 314 of thesubordination pole 262 includes ametering slot 264 that surroundsactivation bar 238. Thesecond end 318 of thesubordination pole 262 is urged upwardly by acam 330 during forward movement of thecocking mechanism 46 upon activation of thegas release mechanism 30. Upward movement of thesecond end 318 of thesubordination pole 262 moves theactivation bar 238 downwardly, compresses thereturn compression spring 254 and aligns the throughhole 246 of themetering rod 234 with thechamber 18. This permits thecompressed gas 138 to drive theparticulate projectiles 38 out of thechamber 18 and through thebarrel 22. Downward movement of thesecond end 318 of thesubordination pole 262 causes theactivation bar 238 to move upwardly as urged by thereturn compression spring 254. This allows theparticulate projectiles 38 to fill the throughhole 246 of themetering rod 234 as it moves in theprojectile storage magazine 34 surrounded by theparticulate projectiles 38. - (8) In still another variant, as illustrated in

Thetab 272 is located adjacent to aside edge 276 andfront end 280 of anupper surface 284 of theprimary gear rack 334. The activatingtab 272 has a contouredinner surface 288. The contouredinner surface 288 is sized, shaped and located to engage afront edge 292 of thecam lobe 268 as theprimary gear rack 334 is moved rearwardly and forwardly during operation of thecocking mechanism 46. Engagement of thecam lobe 268 causes upward movement of themetering rod 234 followed by downward movement of themetering rod 234 during operation of thecocking mechanism 46. Such movement serving to dislodge anyparticulate projectiles 38 adhering to themetering rod 234. - (10) In a further variant, engagement of the
cam lobe 268 by thecam activating tab 272 during forward movement of theprimary gear rack 334 during operation of thecocking mechanism 46 provides an auditory confirmation of completion of the operation. - (11) In still a further variant, as illustrated in

This causes asecond end 382 of thepivot 154, to engage anupper protrusion 150 at anupper end 390 of atrigger 142 of the compressedgas release mechanism 30, thereby preventing activation of themechanism 30. Thecontrol slot 348 causes downward movement of saidfirst end 374 of theinternal safety pivot 154 to a loweredposition 380 upon completion of forward movement of theprimary gear rack 334 and saidcontrol slot 348. The downward movement permits release of theupper protrusion 150 of thetrigger 142 and permits activation of thegas release mechanism 30. - (12) In yet a further variant, as illustrated in
Figures 1 and16 , thestock 50 further includes asight glass 422. Thesight glass 422 is positioned adjacent themagazine 34 and permits a view of alevel 426 of theparticulate projectiles 38 contained in themagazine 34. - (13) In still a further variant, as illustrated in
