WHEELED GUN CARRIAGE HAVING- DIVERGIBLE TRAIL.

m in guns of the known type, having divergible trails, wherein the trails carrying the anchoring devices are capable. for firing,

of assuming oblique positions relatively to vthe combined wheeled axle and carriage head in which the gun pedestal (carrying the gun barrel) is adapted to swivel.

The improvements enable the pivotal axis] of the gun pedestal to assume its vertical position at all. times notwithstanding the transverse inclinations of the wheeled axle or the longitudinal inclinations of the carriage head. f

For this purpose the swivel pivot pin of the gun pedestal, instead of being mounted directly in the carriage head, is mounted in a gun mount which'is pivoted to the carriage head. and upon which the elevating mechanism of the gun barrel is supported.

The uprighting of the. pivotal axis is pro duced either by a double transverse and longitudinal movement of the combined gun mount and elevating, mechanism in the carriage head. or'by a displacement of the gun mount relatively to the carriage head on the one hand, and of the combinedcarriage head and gun mount relatively to the wheeled axle on the other hand.

Various practical examples of this in vention are illustrated in the accompanying 40 drawings in which:

Figs. 1 to 6 inclusive illustrate afirst practical example. a I Fig. 1 is a'longitudina-l elevation of the general arrangement.

Referring to Figs. 1 to 6, the improved gun comprises a wheeled axle, that is to say an axle A and two wheels B. i

The carriage head 0 is fixed to the wheeledv axle for firing. Nevertheless for transport, this carriage head maybe sus: pended elastically from the wheeled axle by any suitable known means as is assumed in the illustrated exampleit This suspension may comprise for in stance. leaf sprines D arranged between the. axle .A. and the carriage head C, and which can be rendered inoperative by means of snrags E carried by screw-threaded rods that are actuated by means of hand wheels 6. r

This possible obliquity votthe trails relatively to the combined wheeled axle and carriage head maybe produced by any suitable known means. i y

The mechanisms that allow joi effecting "these ufirigh tin'g movements may be constructed in practice in .various Ways.

I turns JII the bearings C ofthe ,ca'rriageliead, whilst the journal of the wheeled axle A turns in the wheels B.

The hereinbefore described j; apparatus is combined with a spe'clal construction of the elevating mechanism the latter being wholly supportedfby the movable gun. mount.

The mechanism in the illustratedexample comprises in the known manner'toothed sectorsR finedto the'gun cairiage'ciradle S.

Motion is transmitted to these {sectors (for el-evati m or de ressine thecradle ,b means b a i y of pinions fixed on ashaft it which is journalle d in a bracket U Getting a pivot pin u whose axis is situated in the prolongation of the axis of the swivel pin ,9 of the gun pedestal. A footstepbearing H for/this pivot pin u,"is formed-in thegun mount The bracket U forms in its turn a footstep bearing for a shaft. Vjon which is fixed a worm V meshing with a worm wheel T fixed on "the shaftlt. The shaft V ispextended upwardly; to Work in a recess-in the v swivel P l R f/ and tfcarries bevelplnion v which can be actuated by means ofa gearin -v v -o carried by the gun pedestal.

ince the bracket U is to share'in the movement of the gun pedestal G in the trainingmovements of the gun, it is engaged by means of a square collar U upon a correspondingly shaped collar 9 of the swivel pin 9.

In the modification illustrated in Figs. 7 and S, as in the preceding example, the swivel pin 9 of the gun pedestal G is mounted in a gun mount H. This latter is pivoted directly by means of journals I in bearings C of the carriage head in such a manner as to be able to assume, relatively to the latter, avarying longitudinal inclination that will enable the axis of the swivel pin 9 to be returned into a vertical plane, irrespectively of the longitudinal inclination that is assumed by the carriage head C in firing.

On the other hand, the combined carriage head C" and gun mount H are capable, in the case of a transverse inclination of the wheeled axle A, of being operated relatively to the latterfor the purpose of returning the axis of the swivel pin 9 into the vertical.

For this purpose the wheeled axle A is provided with two laterally projecting journals J engaged in bearings C of the carriage head C.

The uprighting of the swivel pin of the gun pedestal by the rotation of the journals 1, is produced by actuating a hand wheel m which act-uates through a gearing m 2-, a long screw M journalled in the carriage head C. The rotation of this screw causes the movement of a nut L which is engaged by means of pins L in bearings formed underneath the gun mount H.

The operating of the combined carriage head C and gun mount H around the journals J. is produced by the actuation of a worm' /V whose spindle W provided with an actuating hand wheel it, is journa led in the carriage head C. The screw mesh-es with helically toothed sector X fixed on one'oi the journals J.

The movement of the screw on the fixed sector X causes the carriage head C to turn in such a manner that the gun mount H and the gun pedestal Gr carried by it shall be caused to share in this movement.

The elevating mechanism comprises, as in the preceding example, toothed sectors R fixed to the gun carriage cradle S, and to which motion is transmitted through pinions T fixed on a shaft t. This shaft is journalled in a bracket U carrying a pivot pin 14 whose axis is situated in the prolongation of the axis of the swivel pin 9 of the gun pedestal. A. gearing ;o 22 '21 o transmits the motion through a shaft V mounted in an axial recess of the swive pin 0 and carrying a worm by which the motion is transmitted to a helical. wheel T fixed on the shaft 25.

wheeled axle.

This elevating mechanism bears, as will slides H working on arc-shaped ribs having their centre on the pivotal axis.

In the modification illustrated in Figs. 1'1, 12 and 13, the pivot for the transverse uprighting of the combined carriage head C and the gun mount H carrying the gun pedestal G, is constituted by a removable axle J which extends through the wheeled axle A and two frame plates of the carriage head C.

The removability of the rocking axle J allows of providing an elastic suspension for the road wheels between the carriage head C and the axle A. This suspension may, for instance, compriseleaf springs D whose buckle D may be suspended by means of links (Z and blocks a fixedto the axle A,

whilst the main. leaf is pivoted by shackles to the carriage head C.

For firing, the links al are unhooked and the axle J is placed in position. I

The pivotal motion of the combined car- G around. the axle J may lie-produced, as shown in Fig.'11, by moving the carriage head C by means of a nut y, formedon the actuating hand wheel Y andiworked on a screw-threaded rod Y jointed at e to the For transport, it it be desired to bring the elastic suspension into operation, the combined nut fl/ and screw Y is turned down into the position indicated in dot and dash lines (Fig. 12), thus disengaging the nut from the notch 0 formed in the carriage head wherein the'said nut was held by its end collars. v

In the modification illustrated in Figs. 14

and 15. the elastic suspension between thecarriage head C and the wheeled axle 'A is constituted by a leaf spring D arranged in the longitudinal axial plane of the wheeled. axle. The buckle D of this spring is'here fixed to two frame plates D pivotedon pins C proiecting internally from the bearings of the pin J.

For transport, inthis .case it is sufficient to withdraw the pin J and tot'urn'down'the actuating hand wheel Y, whereas to render the suspension inoperative it is sutlicient to reinsert the pin J.

Inthe constructionalform illustrated in F gs. 16,17 and 1R,the' gun mount H in wh ch the sw vel pin 1 of the gun pedestal G is mounted, has two laterally projecting riage head, gun mount H and gnn pedestal I trunnions I, by means ofwhich itis journalled inthe carriage head for the purblock A in an arcshaped slotted guide Ci of the carriage head,- the trunnions I. 2 v y The. pivotal movement of the gun mount "l-l'forthe purpose of longitudinal uprighu neither is the elevating mechanism.

gards the uprighting movement in the transing, is produced by a means which is identical'to that indicated in the example illustrated in Figs. 7 and 8.

The uprighting mechanism is not shown,

As reverse direction of the combined carriage head C and gun mount H, it isproduced by actuating in the direction corresponding to that of the inclination, screw-jacks pivoted between the carriage head and the wheeled axle section. These screw-j acks compriseior each wheeled axle section a screw-threaded rod Z which is pivoted at its upper end to the correspondingsection of theaxle A, and works in a nut Z that is capable of turning in the carriage head 0-.

Rotational motion can be imparted to the nuts Z so as to causethem to turnin opposite directions to each other. For this purpose'bevel teeth are formed'on these nuts, meshing with bevel pinions Z fixed on the ends vot' the shaft Z Motion is imparted to the shaft Z by' means of a pinion Z which-meshes with one of the pinions Z and which is fixed on a shaft Z operable by means of a hand wheel Z and journalledin the carriage head C.

For transport an elastic suspension may be provided between the axle sections A and the carriage head C. by-means of a leaf spring D whose buckle D 'is formed in the carriage head. the main leaf of the spring being hung by means of shackles D from v the axle sections A, When it is desired to render the elastiosuspension operative, 1t 1s of course necessary to undo the coupling between the screws Z and the wheeled axle sections.
