EUG-NE SCHNEIDER, 0F LE CREUZOT, FRANCE, ASSIGNOR TO SCHNEIDER & CIE., OF PARIS, FRANCE, A LIMITED JOINT-STOCK COMPANY 0F FRANCE.

LIGHT-ARTILLERY GUN.

Specification of Letters Patent.

Patented July 22, 1919.

To all whom t may concern.'

Be it known that I, EUGNE SCHNEIDER, a citizen of the Republic of France, residing at Le Creuzot, France, have invented a new and useful Improvement in or Relating to Light-Artillery Guns, which is fully set forth in the following specification.

This invention has for its object to provide an improved piece of light artillery so constructed as to be capable of being easily carried by troops in the assault, and of being readily moved and handled in the line trenches and in the communicating trenches.

One of the characteristic features of the improved piece of artillery is that the gun barrel or its cradle has formed in one piece with it or suitably fixed to it a rear appendix by means of which it is pivoted through the medium of a universal joint, such as a ball and socket joint, to an anchoring device, such as a platform or table provided with a spade; the elevation and training of the gun being effected by directly turning the gun barrel or its cradle aboutvthe said ball and socket joint on the anchoring device.

The supporting of the forward part of the gun barrel may be effected by various means, such as for instance extensible, telescopic or other supports, or by straight racks or curved racks having their geometrical center in the ball and socket joint by which the gun barrel is connected to the anchoring device, the gun barrel being adapted to be locked in its various positions of elevation by means of catches or teeth.

According to the invention the forward support consists preferably of a train of wheels, and the turning of the gun barrel about the ball and socket joint is effected by longitudinal and transverse displacements of the gun carriage axle relatively to the gun barrel, and of the gun barrel relatively to the said axle.

Various embodiments of the invention are illustrated by way of example in the accompanying drawings in which Figures l to'G show one embodiment.

Fig. l is a side elevation` partly in section along the axis of the gun in ring position'.-

Fig. 2 is a corresponding plan.'

Fig. 3 is a cross section on the line III- III of Fig. l.

Fig. 4 is a side elevation of the gun in position for transport.

Fig. 5 is a section of a detail on the line V-V of Fig. 1; and

Fig. 6 is a part side elevation showing the gun in position for firing at very low angles of elevation. v

Figs. 7 and 8 are vertical cross sections illustrating two modifications.

Figs. 9 and l0 are side elevations of another modiication showing the gun in three different positions of elevation. f

Figs. l1 and 12 are respectively a side elevation in partial section and a plan of a further modification of the invention.

In all these figures, A is the gun barrel which is provided according to the invention, as a continuation to the rear of its breech, with an appendix B by means of which it is pivoted by a ball and socket joint C to a suitable anchoring device such as a spade platform D.

In the examples shown, the appendix B is assumed to -be carried by the gun barrel, but it may equally well be carried by the cradle in which the gun barrel is arranged to recoil in the usual manner and carry with it one of the elements of the recoil brake. Although the appendix B is shown as being formed in one piece with the gun barrel, it may eouallywell be afhxed to or assembled with the latter by means of any suitable locking devices that will allow of taking the gun to pieces for transport of the parts separately. j

In the example shown in Figs. 1 to 6the ball and socket joint C is itself pivoted by means'of a longitudinal pivot pin c in a block b which forms the rear end of the appendix B. The ball and socket joint is further mounted on a transverse pivot pin d carried by the spade-platform D, this mounting comprising two truncated conical recesses in the ball that allow a limited transverse movement of the ball on the pivot pin CZ. The ball, is engaged with a slide block D1 provided with a tail Z1 constructed as out, which can. be moved along a long loef 'wheels wardly, it can be brought into the position shown in Fig. 4, and locked in this position. by means of a pin inserted in the lugs b1 and Z2 which are provided respectively on the block b and the platform D. The bar Ffcan then serve as a push bar for transport purposes.

The appendix B is preferably so constructed as to act as a charging guide or chute either directly by its shape Y or` by means of a suitably shaped inner plate B1 xed to the sides of the appendix proper.

The forward support of the gun barrel consists in the examples shown in Figs. lto 10, of a train of wheels, that is to say, of a gun carriage axle G with two wheels I-I, H

In the examples shown in Figs. 1 to 6, and in Figs. 7 and S, the elevation of the gun barrel as a result of the turning of the ball and socket joint C in the anchoring device D, is eected by a longitudinal displacement of the forward support relatively to the gun barrel, while the' training of the gun barrel is eiected by sliding the latter along the axle. For this purpose the axle G is formed with a longitudinal groove g (Figs. 2 and 8),in which there is adapted to slide by means of a corresponding tenon a member such as a pinion I meshing with a corresponding rack c formed on the underside of the gun barrel or of its cradle (Figs. 1 to 6). A longitudinal displacement of. the train' of for the purpose of elevating the gun is produced by rotating the axle G and the pinion I thereon by means of operating handwh'eels J which are fixed on the said axle. The pinion rolls over the rack, where by the support can be brought into the de sired position, for instance into the extreme position of greatest elevation indicated in dot and dash lines in Fig. 1. The gun barrelcan then be fixed in the desired position, for instance by means of the device shown, consisting of a U-shaped clamping member I journaled with its arms on the axle G. These arms inclose the pinion I between them. Inner packing pieces on the said arms act as cheeks bearing against the surfaces of the gun barrel. The crosspiecel of the clamping member is formed as a nut in whichworks a screw L carrying a clamping jaw L1 on its end.

v When it is desired to be able to elevate the gun barrel through very low angles the gun barrel is provided with a second rack al.

formed on .be produced by rollingthepinion I over the rack al.

Coarse training is'el'ected by simply pushsing the vgun barrel transversely along the `axle G, the ne training being obtained by operating the ratchet mechanism E-e.

In the modification shown in Fig. 7 the gun ybarrel has-tworibs a, al, provided in substitution for the racks shown in Figs. 1 to 6; they form a rolling track for a roller I adaptedto rotate on-the axle, the gun being locked inthe desired position'of elevation lby means cfa clampingapparatusl K--L-L1 orfany other suitable device.

fInthe modification shown in Fig. 8 the train of wheels comprises an axle G carrying av pinion I which can move over a single lower rack a, lwhich axle is itself adjustable kvertically with relation to the Wheels I-I. The axle G is journaled at each end in a bearing M iwhich can slide in a guide N1 a hollow journal N on which the hub of the wheel can turn. T he bearing M can be raised or lowered in its guide by means of a screw O working in the said guide. Fo'r transport the axis of the axle G is brought in linewith the axes of the hollow journals 1I, and the keys fm, of the hand- `wheels J are removed, so that then the journals can be mounted on the axle.

' In the modification shown in Figs. 9 and 10 the forward support of the gunbarrel consists also of a train of wheels li-H G carrying on its axle G a pinion I adapted to slide in a groove for the purpose of training the gun barrel. rIhe elevation of the gun barrel is effected in this modification by rolling the pinion over a toothed are P carried by a collar 10 which can be fixed in place on the gun barrel in two positions 180 degrees apart, as shown respectively in Figs. 9 and 10. Clamping apparatus similar to that shown in the preceding gures is provided for the purpose of fixing the gun barrel inany desired position of elevation.

In the modification shown in Figs. 11 and 12 the forward support of the gun barrel is constitu-ted by two toothed arcs Q, carried by a circular soleplate q which is adapted to turn in a forward anchoring bedplate B. Inl this modifica-tion the ball and socket joint C is movable in a slide block S working in an arc-shaped guide rI mounted on the spade platformD. i' rIhe gun barrel is trained by shifting the slide block S in its arc-shaped guide by means of a rack and pinion gear actuated by a lever andV ratchet as shown.

The gun barrel is elevated by causing two pinions U to roll over the toothed arcs Q. These pinions U are carried by a shaft a journaled in a collar V carried by the gun barrel.

As shown in Fig. 3, when the forward support consists of a train of wheels, its bulk may be reduced by shifting the said wheels along the axle, for transport purposes or for bringing the gun into firing position in `the trenches.

It is to be understood that the details of the gun, such as the breech'mechanism, the firing mechanism, the sighting and aiming devices, the constructional details of the spade, platform, etc., may be varied at will.
