AIR PISTOL Filed Feb. 13. 1928 Dwz-afar: Haz/aq fe/Zwez'sser/ Patented June 3, 1930 HUGO SCHMEISSER, F vSTIHL, GERMANY AIR rrsroi.

Applicationd'led February 13, 1928, Serial No. 254,135, and intsermany January 25, 1927.

In the constructional types of air pistols so far known the cocking of the air piston is eiiected either byy means of a special key supplied with the weapon, or else by means C of the barrel which in this case serves as the cocking lever. Both constructional forms have practical drawbacks as, in the first, the key is liable to he lost while in the second the barrel is apt to be bent through repeated use.

These defects are avoided according to the present invention by reason ofthe fact that the setting of the piston is cll'ected by tilting an air cylinder upwards which projectsrearwardly of the butt of the weapon and the piston of which cooperates with a setting lever located in the back of the butt.

Such a construction not only obviates the defects mentioned above, but possesses the advantage that it is possible to provide as large an air chamber as possible Without substantially exceeding the longitudinal dimensions determined by the barrel and butt of the pistol. In addition to this a very favourable centre of gravity position is obtained for the weapon when held in the hand, which is a very important considcrationrin air pistols used for sport purposes. By means of the air cylinder, which is adapted to be tilted upwards, and in which the barrel is' located, a large lever arm is created by means of which the pistol can be cocked or set without trouble and without it being necessary to have recourse to a special implement or tool.

The accompanying drawings show av constructional form of the invention.

` Figure 1 is a lateral elevation of the air pistol in the closed osition.

Figure 2 shows t e pistol also 1n lateral elevation but partial longitudinal section, 0 with the air cylinder and the barrel, in the 1% upwardly tilted position.

Figure 3 is a side view partly in section of the barrel and a portion of the cylinder, and

Figure 4 is an elevation of the air piston.

As can be readily seen from the drawings the air cylinder b is pivotallymounted upon the butt a of the pistol and carries the barrel c at its forward end. The attachment of the air cylinder is effected in such a wa that it projects beyond the rear part of the utt, but

at the same time it does not materially exceed the vertical plane of the rear lower end of the butt.

In the air cylinder there is mounted inl the manner already known the air piston ai with its pressure spring e bearing against the end cap f.

v For the purpose of cooking or setting the weapon, in the piston part of the butt a the' cooking lever h is pivotally mounted on the pin g, the free end of which lever engages with the stop z' of the air piston.

Y If the barrel c together with the air cylinder b be swung upwardly on the pivot pin y' away from the butt a, the lever h will push the air plston d towards the rear of the air cylinder Z) to such an extent that the sear c will spring into the recess m in the piston. After this the air cylinder with the barrel is swung back to its closed or ring position against the butt. l

As may be seen from Figure 3 the 4barrel is so mounted upon the air cylinder as to b e tiltable and ixable, in such a way that an easy and commodious introduction of the shot into the barrel is rendered possible.

The trigger o when pulled presses against the lever arm p of the sear lc, whereby the piston is freed from tension and the shot is ejected from the barrel. The projection s provided on the lever arm p serves as a pressure surface for the trigger.

Having now particularly described and as- -certained the nature of my said invention and in what manner the same is to' be performed, I declare that what I claim is 1. An air pistol comprising a butt; an air cylinder pivotally mounted on said butt at approximately intermediate the ends of the cylinder so that it projects rearwardly of the rear part of the butt; and a spring-actuated piston in said cylinder which is placed in cocked position in the cylinder by forcin the rear end of the cylinder toward the utt around the pivotal mounting.

2. An air pistol comprising a butt; an air cylinder pivotally mounted on said butt at approximately intermediate the ends of the cylinder so that it projects rearwardly of the rear part of the butt; a 'cooking lever piv- 100 otally mounted on said butt; and a springactuated Vpistonhin said cylinder which 1s laced in cocked position in the cylinder by orcing the rear end of the cylinder toward the butt around the pivotal mounting whereby the lever forces the piston backwardly in the cylinder.

3. An air pistol comprising a. butt; an air cylinder pivotally mountedl on said butt at approximately intermediate the ends of the cylinder so that it projects rearwardly of the rear part of the butt; a cooking lever pivotally mounted on said butt; a spring-actuated piston in said cylinder which is placed in cocked position in the cylinder by forcing the rear end of the cylinder toward the butt around the pivotal mounting whereby the lever forces the. piston backwardly in the cylinder; and a sear pivotally mounted to the cylinder for holding the piston in the cocked position.

In testimony whereof I aflix my signature.
