WHEELED GUN CARRIAGE HAVING DIVERGIBLE TRAILS.

Application filed November 27, 1922.

To all whom it may concern:

Be it known that I, EUoizNE SCHNEIDER, a citizen of the Republic of France, residing at Paris, France, have invented new an useful Improvements in or Relating to WVheeled Gun Carriages Having Divergible Trails, which is fully set forth in the following specification.

This invention relates to improvements in the invention described in my copending application, Sr. No. 476,302, filed June 9, 1921.

The present invention is illustrated in detail in the accompanying drawings in which Figure 1 is a partial longitudinal sectional elevation.

Figures 2 and 91* comprise a corresponding horizontal section.

Figures 3 and 3 comprise an end elevation with partial cross-sections.

Figure 1 is a partial section taken along the line 4 1 of Figure 3.

Figure 5 is a partial section taken along the line 5-5 of Figure 2.

Figure 6 is a partial longitudinal sectional elevation of a modified construction of the elastic suspension of the gun, for transport.

The improved gun according to the present invention comprises in the known manner a wheeled axle, that is to say, an axle A with two wheels B. The carriage head proper C is fixed to the wheeled axle during firing, but it can be suspended elastically from the said axle for transport, as is assumed to be the case in the example de scribed in my aforesaid earlier patent.

The suspension may comprise leaf springs D interposed between the axle A and the carriage head C. The carriage head 0 comprises for this purpose a block or buckle D in which the bundle of leaf springs is fixed, the main leaf being connected by means of knuckles D to rings D attached to the wheeled axle A. The combination of the two trails F. is capable of warping, in other terms, of assuming oblique positions relatively to the combined wheeled axle B-AB and the carriage head C. The said trails are pivoted at one end 7 to a cross-piece F and each carries at its rear end an anchoring device (not shown).

The pivotal connection of the trails to the combined wheeled axle and carriage head is Serial No. 603,699.

effected in the manner described in my earlier patents, numbered 1085168 and more particularly 1084490.

This pivotal connection comprises a hollow longitudinal journal F 2 mounted in a bearing d which is fixed to the block D, the latter being in its turn journalled in the carriage head C.

As hereinafter described, the combination d D is fixed to the carriage head C for firing, in such a manner that the combined trails FF -F can rock relatively to the combination C(Z --D in other words, relatively to the carriage head which is itself fixed to the axle tree A. This rocking movement of the trails F-F -F is effected by rotation of the tubular journal F in the bearing (1 In the same manner as described in my aforesaid earlier patent, the pivot pin 9 of the gun pedestal G which carries the gun barrel, instead of having its foot-step hearing formed in the carria e head C, is located in a gun mount H w ich is pivoted to the carriage head C. This pivot pin 9 can be returned at any time into the vertical position for which purpose it can receive both an uprighting or erecting a longitudinal uprighting movement on the one hand, and a transverse uprighting movement on the other hand.

For the purpose of effecting the longitudinal uprighting movement the gun mount H is pivoted to the carriage head C by means of a pivot pin I arranged vertically underneath the centre of gravity of the rocking mass and in front of the axle tree A. This pivot pin is mounted in an eye 0 of the carriage head (Figs. 1 and 3), and extends through two bearings it formed on the gun mount H.

For the purpose of effecting the transverse uprighting movement of the pivot pin g, the combination constituted by the carriage head C pivot pin I, gun mount H and pedestal is arranged to pivot around the trunnion 03 For this purpose the carriage head C has projecting laterally from it a helical toothed sector C (Fig. 3) meshing with a worm J whose shaft is journalled in a bearing A fixed to the axle tree A.

A rigid connection between the carriage head and the axle tree A during firing is produced by the fact that the combination dD is fixed to the axle tree A by means of a pin K (Figs. 2 and 3). On the other hand a rigid connection between the carriage head C and the hollow journal 65 is produced by the meshing between the toothed sector and the worm J carried by the axle tree A.

The rotation of the carriage head 0 around the journal (Z1 for the purpose of effecting the transverse uprighting of the pivot pin 9 is produced by means of a sultable gear for rotating the shaft of the worm J. This gear comprises for instance a bevel pinion j meshing with a pinion j fixed on a shaft j which is journalled in bearings fixed to the axle tree and can be operated by means of a hand-wheel y' The mechanism for uprighting the pivot pin 9 in the longitudinal plane of the gun comprises, as shown in the drawings, a toothed sector H formed as a projection from the gun mount H, and meshing with a pinion L. The shaft of this pinion is journalled in a forked bearing block m formed on a journal M fixed to the carriage head C. This journal M is co-axially mounted within the longitudinal tubular journal F of the combined trails.

The transverse uprighting is effected by the pivotation of the combined trails around a geometrical axis of oscillation relatively to the combined wheeled axle and carriage head.

The mechanism for effecting the movement of the sector H over the pinion L for producing the longitudinal uprighting movement, comprises for instance, as shown in the drawings, a worm wheel L fixed on the shaft of the pinion L, meshing with a worm L which receives its motion from the pinion L meshing with a pinion L whose shaft, which is journalled in bearings fixed to the block m, can be actuated by means of a hand wheel L The gun elevating mechanism is fulcrumed on the gun mount H. It comprises, on the gun pedestal G, two toothed sectors G each meshing with a. pinion s mounted on a shaft 8 journalled in bearings fixed to the underside of the cradle S. The rolling of the pinions s over the sectors G is produced, for instance. by means of a transmission gear consisting of a worm wheel 8 fixed on the shaft 8 and meshing with a worm s the shaft of which carries a pinion s which can revolve with the said shaft in a box .9 fixed to one of the trunnions S of the cradle S.

The pinion s is driven by a pinion 8 actuated by means of a hand wheel 8 whose geometrical axis coincides with the axis of the trunnion S 7 For training the gun, the gun pedestal G is engaged with the gun mount H which latter comprises a toothed sector H formed on an arc struck from a centre situated on the axis of the pivot pin g. The movement of the gun pedestal over the sector H is produced by means of a suitable transmission gear consisting, for instance of a worm N whose shaft 11. is journalled in bearings fixed to the gun pedestal, and carries a bevel pinion a which receives its motion through gearing n -n n" actuated by means of a hand-wheel n.

As hereinbefore described, the combination cZ -D upon which the carriage head C is adapted to rock may, for the purpose of effecting the transverse uprighting movements, serve as a bearing block for a bundle of leaf springs D, the main leaf of which is suspended from the wheeled axle A. This elastic suspension is rendered inoperative during firing, by the block D being locked in position by means of the pin K, and also by the engagement between the sector C and the worm J.

In order to bring the elastic suspension into operation for transport, a means is provided for disconnecting the sector C from the carriage head (1, or more strictly speaking from an arm constituting a projection from the latter.

As shown, the sector C is connected to the said arm, by means of a pin 0 (Fig. 4:).

If the two pins K and 0 be both withdrawn, the sector C will remain rigidly connected to the axle tree A, and the arm projecting from the carriage head C will be capable of sliding over the said sector.

For the purpose of facilitating the mounting of the longitudinal axis of pivotation of the combined trails relatively to the combined axle tree and carriage head, as well as the mounting of the elastic suspension, a recess is formed in the axle tree A (Fig. 1) for the reception of a portion of the block D together with the bundle of leaf springs carried by the latter.

In the modification illustrated in Fig. 6, the combination (l -JD, around which the carriage head C can rock for effecting the transverse uprighting movements, is constructed in the form of a rocking beam to the ends of the arms of which there are articulated blocks D, each carrying a bundle of leaf springs D the main leaf of which is suspended from the axle tree A.

This modification has the advantage of increasing the transverse stability of the gun during travel.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is z-- 1. A wheeled gun carriage comprising, in combination. an axle, a block pivot-ally secured thereto having a longitudinally extending bearing portion. a pair of divergible trails adapted to rock about said portion, a carriage head pivotally secured to said portion, a mount pivotally secured to said head, a pedestal having a pivot pin, means pivotally securing said pedestal to said mount, and means for moving said pivot pin to a vertical position from any inclined position.
