SINGLE-TRAIL GUN-CARRIAGE.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed March 31, 1919. Serial No. 286,483.

To all 'whom it may concern:

Be it known that I, EUGENE SCHNEIDER, citizen of the French Republic, and a resident of 42 Rue dAnjou, Paris, France, have invented new and useful Improvements in Single-Trail Gun-Carriages, which invention is fully set forth in the following specification.

This invention has for its object to provide an improved apparatus for allowing of obliquities of level between the front and rear portions of single-trail gun carriages during firing, wherein the front portion is constituted by an endless track, and wherein the gun is trained by shifting the trail.

According to this invention the trail is pivoted at its tail by means of a pivot pin situated in its longitudinal axial plane,- to a sliding carriage engaging an arc-shaped guide formed on an anchoring platform and adapted to turn on a center constituted by the axis of pivotation of the gun pedestal upon the endless track. By this means the whole composed of the anchoring platform and the sliding carriage are able to have, during firing, inequalities of level relatively to the whole composed of the trail and the front support of the gun constituted by the endless tracks.

Two forms of construction and application of this invention are illustrated by way of example in the accompanying drawings in which:

Figures 1 to 4: illustrate a first constructional form.

Fig. 1 is a side elevation partly in vertical section of the gun carriage in the firing position.

Fig. 2 is a plan partly in section on the V line IIII of Fig. 1.

Fig. 3 is a cross section on the line III-III of Fig. 1.

Fig. 4 is a cross section on the line IVIV of Fig. 1.

Figs. 5 to 7 illustrate a second constructional example of the invention;

Fig. 5 is a side elevation partly in section showing the gun carriage in firing position;

Fig. 6 is a horizontal section on the line VIVI of Fig. 5;

Fig. 7 is a cross section on the line VIIVII of Fig. 5.

As shown in Figs. 1 to 4, the gun carriage trail A is trunnioned in the usual manner on a gun pedestal B which is adapted in its turn to rotate in or on a frame C resting on the endless track trucks D.

According to this invention, the trail A is jointed by means of its tail A along its longitudinal axis aa to a sliding carriage E engaged-on an arc-shaped guiding track f formed on an anchoring platform F of known construction. The joint between the tailA and the carriageE may be efiected as shown, by means of a pin a formed on the tail and engaged in a corresponding bearing in the sliding carriage E. The retention of the tail in the sliding carriage is assured by guide ribs a engaging grooves 6 formed in the sliding carriage. The joint may however be effected in the reverse manner by providing a pin on the carriage E working in a corresponding bearing formed in the tail A The shifting of the gun carriage for the purpose of training the gun may be produced by means of any known mechanism acting upon the carriage E. In the example shown in Figs. 1 to 1, a nut G is mounted on a screw H which is journaled at its ends in bearings h on the platform F. The nut G is held between two cheeks E of the carriage E. By actuating the screw H by means of a ratchet key I, the nut G and the carriage E can be moved in the desired direction.

It will be readily understood that in firing, the platform F will be able to have obliquities of level relatively to the front supports of the gun carriage without any, injurious effect being produced upon the anchoring of the gun carriage.

In the example shown in Figs. 5 to 7, the frame C on which the gun pedestal B is pivoted, is movable about a transverse axle K journaled at its ends in bearings L formed on or carried by the two endless track trucks D. This manner of connection between the gun carriage and the endless track trucks forms the subject matter of another application for patent by the present applicant, filed February 28, 1919, Serial No. 279,879.

The frame C is. fixed by means of two arms G to one of the endless track trucks D. The manner in which the present invention is carried into effect is practically the same in this example as in the preceding example. By way of modification, the

mechanism for shifting the carriage E along the arc-shaped guide track F, is different from the one shown in Figs. 1 and 2.

The arc-shaped track Fis formed with teeth F with which engages a pinion 1W fixed on a spindle m journaled in the carriage E. This spindle is adapted to receive at its outer end a ratchet key N.

In both the examples hereinbefore described, when the gun carriage is in position for firing, the anchoring platform F may be connected to one of the endless track trucks D by means of rods P provided with turnbuckles for adjusting their length.

lVhat I claim is 1. The combination with a trail gun-carriage, a mounting on which is pivoted the trail at its forward end to have horizontal angular movement around its pivotal point, an anchoring platform having an arcuate guide centering with the pivotal point of the trail, and a carriage having a pivotal connection with the trail-tail in alinement with the longitudinal axis of the trail, said carriage being slidable on the arcuate guide of the anchoring platform to shift the trail around its forward pivotal point.

2. The combination with a trail gun-carriage, a mounting on which is pivoted the trail at its forward end to have horizontal angular movement around its pivotal point, an anchoring platform having an arcuate guide centering. with the pivotal point ofthe trail, a carriage having a pivotal connection with the trail-tail in alinement with the longitudinal axis of the trail, said carriage being slidable on the arcuate guide of the anchoring platform to shift the trail around its forward pivotal point, and means on the anchoring platform for moving the slidable carriage on the arcuate guide. 7

3. The combination with a trail gun-carriage, a mounting on which is pivoted the trail at its forward end to have horizontal angular movement around its pivotal point, an anchoring, platform having an arcuate guide centering with the pivotal point of the trail, a carriage having a pivotal connection with the trail-tail in alinement with the longitudinal axis of the trail, said carriage being slidable on the arcuate guide of the anchoring platform to shift the trail around its forward pivotal point, a screw rotatably mounted on the anchoring platform, a nut held in the slidable carriage engaging the screw, and meansfor rotating the screw to propel the nut to move the slidable carriage on the arcuate guide.

4. The combination with a trail gun-carriage, a mounting on which is pivoted the trail at its forward end to have horizontal angular movement around its pivotal point, an anchoring platform having an arcuate guide centering with the pivotal point of the trail, a carriage slidable on the arcuate guide of the anchoring platform, and a pivotal connection between the tail-trail and the slidable carriage to permit relative axial movement between the trail and carriage to accommodate relative obliquities of levels of the anchoring platform and of the front support of the trail.

5. The combination with a trail gun-carriage, a mounting on which is pivoted the trail at its forward end to have horizontal angular movement around its pivotal point, an anchoring platform having an arcuate guide centering with the pivotal point of the trail, a carriage slidable on the arcuate guide of the anchoring platform, an axial pin and bearing forming a pivotal connection between the tail-trail and the slidable carriage to permit relative axial movement between the trail andthe carriage to accommodate relative obliquities of the levels of the anchoring, platform and the front support of the trail, and an engaged flange and rim connection between the trail-tail and the slidable carriage to hold said members together.

In testimony whereof I have signed this specification.

EUGENE SCHNEIDER.
