AIR GUN.

APPLICATION FILED MAR. 6, I9I9.

Eat-@uuid July 8, 1919.

ATTORNEY ported by a in 30 so that the nose 23 can swing toivar and away from the plunger 21. suitably to engage with the recess 22 when in registration therewith, and is held in such engagement with the plunger 21 by means ofthe spring plunger 31.

The bulb 14 tends normally to assume the distended osition so as to draw air inwardly through t e barrel l0 and after the valve 21 has been closed by raising the lunger 21 and locked by the trigger mem er 2l the compressing of the charge of air is effected by means of a block 32 that is mounted on a lever 33 that is pivotally connected b its rear end with the stock-11 by means o the pin 34. For convenience in holding the charge in the compressed 0r loaded condition I provide a catch 35 for receiving and engaging with thefree end 36 of the lever 33.

A novel feature of the air gun structure described in use is that the expansive qualities of .the rubber bulb, because of which when the pressure on the bulb is released and the walls are free to do so they open out and thereby-draw in the fresh charge of air for compression, may be utilized at the same time for drawin the projectile into the barrel, and the mec anism described is adapted for permitting this to be conveniently done.

One way of doing this would be to release the latch and at the same time hold the compression lever momentarily in the compressin position. Upon release of the lever the bu b will open and in so doing will force the lever outwardly and simultaneously will draw in a fresh charge of air through the barrel, and a projectile positioned at the mouth of the barrel will be drawn inwardly to the proper loaded position by the entering charge of fresh air.

Thus the lever structure described provides means for controlling the drawing in of the fresh charge of air and of controlling loading of the projectile in the barrel.

I claim as my invention 1. An air gun having a barrel, an air chamber, and a collapsible tube connectin the said barrel and chamber, means for co lapsing the said tube comprising a member having a movement in the radial direction relatively to the said tube, the said member 2. An air gun having a barrel, an air chamber, and means of tubular form connectin the said barrel and chamber, the said air chamber being in the form of a bulb of elastic material, means for compressing the said air chamber, and means m the form of a lever for controlling the discharge from the said chamber.

3. In combination in an air gun, a stock, a barrel mounted on the said stock, a rubber bulb seated in the said stock, a rubber tube connecting the said bulb and barrel, trigger operated means for compressing the said tube, and means forncompressing the said bulb.

4. In an air gun having a barrel, an air chamber, and a collapsible tube connecting the said barrel and chamber, means for collapsing the said tube comprising a member having a movement in the radial direction relatively to the said tube and having one end adapted to .engage with the said tube, the said y one end being equipped with a cushion contacting` pad of rubber of appreciable thickness.

5. An air gun constructed and arranged to draw the projectile inwardly along the barrel to the loaded position simultaneousl with the drawing inwardlyof the res charge of air, comprising a barrel, a bulb having expansive walls connected to the said barrel, and a lever serving as means for compressing the said walls and for controlling the expansion thereof.

6. An air gun comprising a barrel, a bulb, a collapsible tube connecting the said barrel and bulb, and devices for collapsing the said tube, the said devices comprising a moving member for contacting with the said tube and having a movement in a radial direction relatively thereto.

7. An air gun as described in claim 2, and the said means for controlling the discharge from the said chamber being provided with a trigger. i
