Definitions
- the system is dependent upon a small cylindrical plastic case in which a diabolo or other form of pellet is inserted.
- the case is very inexpensive to produce and therefore can be discarded or reused.
- the case is strong and able to stand considerable pressure without distorting enabling it to be transported within a variety of magazine systems.
- the pellet case is used as an air seal and is ejected during the loading cycle.
- An internal rim within the case ensures that the pellet is held firmly and cannot fall out or foul the mechanism. It above all ensures that the pellet is fed directly into the barrel in perfect condition providing consistent accuracy.
- the pellet case has similar dimensions as a small caliber firearms cartridge and can therefore be as versatile i.e. magazine systems from conventional weapons can be used in air weapons providing a wider field of designs.
- Fig. 1 shows a shortened axial view of an air rifle as per the invention.
- Fig. 2 shows on enlarged scale the pellet case in side view as per the invention.
- Fig. 3 shows on enlarged scale a detail of the ejector of Fig. 1.
- Fig. 4 shows a further detail of the ejector chamber.
- the weapon is constructed with a cylindrical outer casing 1, the fore end attached to a machined block 13, in which a barrel 2 is fitted, and the rear end attached to a screw-on block containing a trigger mechanism (not shown) .
- the spring and piston air compression system 4 comprises a sliding compression tube in which the spring tension operated piston is contained, the whole is contained within the outer case tube 1.
- the magazine block containing the barrel is machined vertically to provide a channel directly in line with barrel 20 in Fig. 3 in which the magazine 15 fits.
- SUBSTITUTE SHEET has the same diameter as the bore of the barrel and long enough to pass from the rear of the breech block to the barrel, Fig. 1.
- the centre bore of the loading tube passes into the compression cylinder allowing air to be forced directly into the barrel from the cylinder when the weapon is fired.
- Attached to the underside of the breech block, directly below and surrounding the magazine channel, is a rectangular housing made to allow the magazine to pass through into the breech and, by means of a securing catch, holds the magazine in place.
- the pellet cases are plastic cylinders having a wall thickness of approximately twelve micrometers with 5.6 bore the length approximately one and a half centimeters longer than the pellet, i.e. length 1 cm, diameter 8 millimeters.
- the outer wall is tapered outwards to allow the loading tube to pass freely into it.
- a channel is formed around the inner wall.
- the loading tube is extracted through the breech at the same time allowing an encased pellet to move into the vacated space and forcing the empty case from the previous shot into the ejection chamber, Fig. 1.
- the pellet to be loaded is held in position by the spring pressure from below and the underside of the empty case from above.
- the piston is engaged by the trigger unit and is held in that position.
- Ejection is provided by a spring projection- in the side of the cover plate, Fig. 3 and 4, or a separate spring operated lever in the breech.
- the piston is forced into the compression cylinder forcing the compressed air into the barrel and discharging the pellet. This action further tightens the case between the barrel and the cylinder face effecting a secure sealing function.

Abstract
Système de chargement semi-automatique d'armes à ressort, à gaz ou à air comprimé avec des plombs en forme de diabolo, ledit système comprenant une petite gaine plastique (22) cylindrique dans laquelle est introduit un plomb diabolo (21) ou une autre forme de plomb, ladite gaine (22) assurant l'étanchéité à l'air et étant éjectée pendant le cycle de chargement. Un rebord (30) à l'intérieur de la gaine permet de maintenir fermement le plomb et de l'empêcher de retomber ou d'enrayer le mécanisme. On peut introduire un certain nombre de gaines dans un magasin (15).Semi-automatic loading system for spring, gas or compressed air weapons with diabolo pellets, said system comprising a small cylindrical plastic sheath (22) into which a diabolo lead (21) or another is introduced lead form, said sheath (22) sealing the air and being ejected during the loading cycle. A flange (30) inside the sheath makes it possible to firmly hold the lead and prevent it from falling or stopping the mechanism. A number of sheaths can be introduced into a store (15).
