To (ZZZ whom it'miag concern: i 1,
lBe it known that I, Eoeinvn Sonnnroen, a citizen ot-the Republic "of France residing at Paris, F ranee, have invented new and: use ful improvements in apparatus in and relating to trail-carriage guns mounted on endless tracks for a varying the height of the line of fire oi. the guinuwhiclr is ,fully set forth in the following specification.
This invention has torv its object to provide improved apparatus for, varying the height of thevline of fire of a gun eompr'is ing a trail carriage mounted on endless tracks. 1
According to this invention:a-nintermedh ate mechanism is interposed between the gun carriage proper (or any member fixed to the said gun carriage) and the endless track trucks. or the pur poseot varying the heightof the line of tire, the gun carriage is caused to turn around the point of support of the carriage trail tail on the ground, by the action of the aforesaid'interposedmechanism when the latter is actuated." Intth-is manner a'ohange of relative position is produced between the gun carriage head and the endless tracks, eitherhy a turning movement of the endless traeks; around the can riage axlelin which case the endlesstraeks bear upon one of their two heels) or by the carriage axle being ralsed iii-the trucks which are adapted for thispurpose. h

r Referring to Figs. 9 to 12, inelusive,'the

'gear..interposedbetween the te'n'on-carri i L I v a *only through an angle of t5-,-since{the rollendless track trucks, comprises, on the carground. Similarly if the carriage axle riage axle B (which is fixed with relation to the carriage head), two helically toothed quadrants G centred on the axis of the car riage axle on which they are fixed. With the teeth of these quadrants there can be brought into mesh worms 0 supported by spindles 0 which are in their turn carried by the trucks C, being mounted for instance, in the hollow axle (Z of one of the wheels D of the respective truck. T he meshing of a worm O with its respective quadrant G, can be efifected at will by turning the supporting box P of the worm around the spindle 0 by means of a swivelling adjusting screw Q, one of the screwed stems g of which is pivoted to a link P fixed to the box P whereas the other screwed stem is pivoted to a bracket C fixed to the truck.
If it is desired to raise the line of fire, when the parts are in the position shown in Figures 13 and 14 where the worm O is shown in mesh with its respective toothed quadrant, it is sufficient to cause the worms 0 to travel over their quadrants by actuating them for this purpose by means of handwheels 0 fixed on the spindle 0, so that they transmit the motion imparted to the latter, to a pinion meshing with a pinion O fixed to the worm 0.
As the worms 0 travel along their quadrants G, the trucks C turn on the points of support of the endless track wheels E upon the ground as centres. At the same time these points of support move towards the rear of the gun carriage, so that the latter is caused to turn around its anchoring point as a centre. A mutual guidance may be provided between each truck C and its quadrant. G, for instance, as shown in the drawings, by means of a rib C of the truck which remains always in engagement in an areshaped slot G of the quadrant.
If the gun carriage is placed in battery position on perfectly flat ground, the two worms 0 must be moved preferably both at the same time, through equal angles along their respective toothed quadrants in order that the carriage axle B shall remain horizontal in all the raised positions of the line of fire.
If, on the contrary, the gun carriage is placed in battery position on very uneven grounds, a horizontal position of the carriage axle B can always be assured by inclining the two trucks (l through different angles by suitably actuating the respective intermediate mechanism O G.
In this respect Figures 16 and 17 show one of the endless chains or tracks resting upon substantially horizontal ground, whereas the other endless track is inclined by a suitable angle to restore the horizontal position of the carriage axle B notwithstanding the very irregular cross-sectional contour of the should happen to assume an inclination to the horizontal during the firing of a shot, the said axle can be returned intoits proper horizontal position.
For travelling over the ground (Figure 18) the worms 0 are disengaged from the toothed quadrants O by operating the swivelling adjusting screws Q in the proper direction. The trucks C are then free to rock around the carriage axle B in order to adapt themselves to the varying longitudinal contour of the ground.
The pivotal spindle of the worms 0 need not necessarily be mounted in the axle of the guide wheel D of the respective endless chain or track. A suitable support may be provided for it at a suitable point of the truck nearest the axis of the carriage axle 13; thus allowing the use of toothed quadrants G of smaller radius, as indicated in dot-and-dash lines in Figure 13.
Referring to the embodiment illustrated in Figs. 19 to 21. the intermediate mecha nism interposed between the gun carriage and the endless track trucks, comprises in this example, in each truck C, a slot guide R serving to guide an axle box B in combi' nation with devices by means of which the said axle box can be moved up and down in its slot guide, and can be held in place at any desired point of the latter. For the purpose of raising the line of fire, each axle box, as shown in Figures 19 to 21, niay con tain a removable stub shaft S fitting in the axle box or in the hollow carriage axle B, and provided with a pinion S which, when inserted, meshes with a rack C formed on the truck parallel to the slot guide R.
The holding of the axle boxes in the desired positions may be assured by means of holding keys T which are inserted in sockets C C, C provided at different levels in the respective trucks C. Figure 20 shows the gun carriage when it has been moved into the position where the line of fire is highest.
Another embodiment of the constructional example just above described is illustrated in Figs. 22 to 24:, inclusive.
In this example the axle boxes B serve as lodgments for two nuts 5 in which work act-uating screws U pivoted at their upper ends a to their respective true-ks C. Each nut 11 carries a pinion Z). The two pinions Z) can be actuated both at the same time for screw 20 ing the nuts along their screws U, by means of a gear comprising a pinion b meshing with the two pinions b and fixed on a stub shaft Z) journalled in the axle box B The same shaft 6 carries a bevel pinion b meshing with a pinion b journalled in the carriage axle B. This pinion can be actuated by means of a detachable hand-wheel S fitting with a square portion in a sleeve fixed to the pinion 6 Having now particularly described and ascertained the nature of our said invention and in what manner the same isto be performed, we declare that what we claim is :v
1. A trail gun carriage mounted. on endless-track trucks, comprising an axle rotatably mounted on said trucks fonsupporting said carriage, members mounted on said axle and having operative engagement with said trucks, and manually operable means whereby the trucks may be turned about said axle. V
2. In a gun carriage, the-combination of an endless-track truck, an axle rotatably mounted on said truck, a trail secured to said axle, a carriage head supported on said trail, a member secured to said axle, and means secured to said truck and operatively engaging said member whereby a relative displacement between the carriage head and said truckmay be produced.
