Definitions
- the automatic rifle which is intended to replace before long the ordinary rifle cannot have a mechanism similar to that of machine guns or machine rifles which are distributed to companies of specialized gunners. I Its weight should not reasonably. exceed that of the ordinary rifle (4 kgs.) otherwise the soldier is unable to carry the necessary ammunition; moreover the weapon should be easily 1o handled, used, dismounted and readily mounted like the rifles now in use and be provided with a non-automatic firing means for use in case the automatic mechanism is damaged. In this case the nner uses the weapon like an ordinary e o ning and closing the breech bolt and handling the rifle by movements well known to him through long ex erience. When the mechanism is arrange for automatic workin the shots more rapidly an easil and without effort, as'advisable in attac sudden defense for physiological reasons.
- the automatic rifle according to this invention satisfies all the requirements men- 26 tioned above.
- the accompanying drawings show a constructional form of my improved rifle- Figure 1 is a vertical longitudinal section.
- a Figure 2 is a crosssection on line AA'o f 80 Figure 1.
- e Figure 3 shows the device for transformingthe automatic rifle into an ordinary rifle.
- igure 4 is a partial side view.
- Figure 5 is a vertical cross section on line BB of Figure 4.
- the rifle has a recoiling barrel and is of the same weight and size as an ordinary rifle.
- 1 denotes the butt; 2 the breech, 3 the breech bolt, 4 the striker and 5 the barrel.
- the automatic closure of the breech bolt 3 is obtained by means of the teeth 3a on the head of the breech bolt, which by a slight rotation are caused to 511 provided on the inner surface of a short rear extension of the barrel 5 recoiling with this latter by a short extent while the breech remains stationary and is brought forward again y a suitable spiral spring 6.
- the device for rotating the breech bolt to the closed position comprises a short cylinspring 12 are bent over engage against ribs drical coil spring 12 interposed between the front portion of the striker 4 and the bottom of the breech. bolt 3.
- the end turns of the lon itudinally and introduced into a correspon ing hole bored in the striker and breech bolt respectively.
- the spring 12 works under torque stress and as it is mounted under a certain load it tends to rotate the breech bolt 3 with respect to the striker 4. As this latter is guided in a rectilinear direction in the breech by a tooth 4a movable in a longitudinal groove 21; on the breech, the breech bolt tends to rotate towards its closed position, this rotation taking place at the end of itsforward stroke as soon as its tooth 3a is disengaged from the rectilinear guide groove 20.
- the strikin mechanism comprises a cock 18 provided with a resilient tooth 25 capable of longitudinal movement and adapted to engage with the lower face of a stationary cross-piece 26 of the breech 2 for holding the cock 18 in cocked position when it is tilted backwards.
- the trigger 20 is pivoted at 21 to the bridgepiece 15 so that by pulling it backwardly it pushes forward by its upper arm a lever 22 pivoted to the trigger in 23.
- the lever 22 thus abuts the resilient tooth 25 0f the cock and pushes it forward, until it is disengaged from the cross-piece 26 thussetting free the cock which rotates forward snapping against the. striker 4.
- the breech bolt recoils so quickly that the cock is tilted backwards and tends to assume its cocked position before the gunner has time to release the trigger, so that the lever 22 is still in itsforward position and the cock remains in cocked position on account of the fact that its resilient tooth 25 abuts under the rod 22. As soon as 6 the gunner releases the trigger, the lever 22 slides backwards between the cross-piece 26 and the tooth 25 until this latter is set free from the lever and abuts under the crosspiece.
- the cock 18 is provided on top with a side Two reference'letters, e. g., rib 18a ensuring the complete rotation of ring clearly denote whether the cock (Figs. 1 and 2) and preventing it arranged for automatic or to come in frontof the breech bolt upon acing. cidental snapping of the trigger when the Figure 1 shows the safety device constibreech bolt is in its rearward position.
- the r ng 113 n the cartridge cases has the further advantage rotated through a limited angle by means of p itting a, better protection of the fire of an outer milled button not shown forarm against rain, .dust and mud and of s mplicity sake.
- the breech 2 or preferably strengthening the breech. its extension 7 is provided with an equal
- the f th pe atio The gunner opens the breech are the following:
- the ring 113 is rotated in such manner It abuts and-slides the lever 30. gunner is thereby made aware that he and the fire arm.
- the said. loader on the ring 13 which iscaused. to turn, the breech bolt 3 rotates, opens, recoils, ejects the cartridge case, next moves forward under the action of the returnspring 11, pushes a fresh cartridge into the chamber and remains closed.
- An automatic rifie comprising a stationary breech, a barrel at one end of the breech, interengaged toothed connections between the barrel and a slidable breech bolt within the breech, a striker slidably mounted in the breech bolt, a coiled spring connection between the striker and the breech bolt and forming means whereby the interengaged toothed connections between the breech bolt and barrel is maintained and means cooperating with the breech bolt on its rearward movement whereby the barrel will move rearwardly a limited distance, the breech bolt rotated, the toothed engagement disconnected and spring means whereby said striker and breech bolt will be forced to closed position with the toothed engagement between the breech bolt and barrel.
- a breech bolt movable forwardly and rearwa-rdly for automatically loading and unloading said rifle
- a revolvable PIOJGCtlOD cooperable with said breech bolt by rolling friction, whereby the breech bolt is rotatedupon its rearward movement
- a torque spring operatively connected to said breech bolt, whereby upon its forward movement the breech bolt is rotated in a direction opposite to the first named rotation.
