ENTE STAS FT EUG-NE SCHNEIDER, OF PARIS FRANCE, ASSIGNOR TO SCHNEIDER & CIE., PARIS, FRANCE, A LIMITED JOINT-STOCK COMPANY OF FRANCE.

ENDLESS TRACK FOR TRAIL GUN-CARRIAGES.

Application filed February 28, 1919.

To all whom t may concern.'

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

This invention has for its object to provide an improved construction of endless tracks for trail gun carriages. These iinproved endless tracks aie characterized by the feature that the treads or links of the track chains comprise guides forming slides for the passage and holding of anchoring spades. i/Vhen the chains are opened out fiat on the ground it is possible with such endless tracks, to constitute a real platform for firing, the gun carriage remaining normally in relation to the endless tracks, in the position it occupies during transport.

For constituting a platform by means. of these improved endless tracks, this invention comprises the combination of the said endless tracks with a removable soleplate adapted to engage the end treads and serving as a support for the carriage trail. This removable soleplate that forms the rear support for the gun carriage, may also be provided with an arc-shaped guide and with mechanism for shifting the trail along the said guide. According to a modiiication the removable soleplate may be provided with a pivot pin and be combined in this arrangement with a curved aXle serving for staying together the endless track trucks that constitute the front supports of the vgun carriage on the opened-out endless tracks.

According to this invention the track trucks and the vremovable soleplatev maybe provided with suitable devices for hating them upon the opened-out chains. Various constructional examples of this invention are illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of a gun carriage of any desired construction, supported, for iring, on the opened-out endless track chains that are anchored to the ground.

Fig. 2 is a plan thereof.

Fig. 3 is a partial plan drawn to a larger scale of an opened-out endless track anchored to the ground. Y

Fig. 6 is a vertical section drawn to a larger scale, on the line VI-VI of Fig. 2, illustrating a device for fixing the removable soleplate on the end treads of the opened-out endless tracks.

Fig. 9 is a plan of a second modification.

Fig. 10 is a plan of a construction in which the soleplate serves as a guide for the movements of the trail around a front pivot pin, for the purpose of training the gun.

Fig. ll illustrates diagrammatically another constructional form of the soleplate.

Fig. l2 is a diagrammatic side elevation illustrating the improved endless tracks and the gun carriage to which they are applied, in the position for transport.

Each of the endless tracks comprises in the usual manner an endless chain composed of a series of treads A jointed together by pins a and formed with internally projecting ribs A1 that serve as a track for the rollers B of the trucks C.

The constructional details of these known chains may be varied at will. The characteristic feature of the improved construction of chains consists in this that the treads A comprise guides D which when the chains have been opened out flat upon the ground, will form slides for guiding and holding stakes E or other similar anchoring devices.

'l'he guides or slides D are preferably formed as shown in Figs. 2, 3 and 4, by lateral lugs which are arranged along the longitudinal axis of each tread, or of only some of the treads,vand are formed in one piece with the said treads. In each of the lateral lugs and the adjacent body of the slide is a slot to engage an anchoring spade driven therethrough.

By means of chains constructed in this manner it is possible to constitute for the entire gun carriage, a continuous firing platform such as the one shown in Figs. l and 2.

' In order to fprovide a rear support for the trail it is su cient to attach to, the openedout chains, a soleplate F which may for instance be engaged on the inner ribs A1 of the end treads by means of hooks f. Bothv this removable soleplate and the carriage trail G- intended to rest upon it, may be variously constructed. For instance as in the example shown in Figs. l and 2, the trail G is provided with hooks G1 and G2 for its engagement with the soleplate F.

ln the example illustrated diagrammatically in Fig. 10, the trail H of the gun carriage is assumed to be designed in such a manner as to be capable of pivoting on a platform serving as a stay :tor the two endless track trucks C. In this arrangement the soleplate F may comprise an arc-shaped guide F1 having its center in the axis of pivotation-of the Yhead of the gun carriage. The soleplate may comprise any suitable known device l-Il for effecting the displacement of the trail G. As the screw l1 is tangential to the arc of movement of the trail H, the extremity oiE the latter is recesse(L horizontally to accommodate the relative movement of the screw and trail as the latter is turned on its pivot.

ln the example which is diagrammatically illustrated in Fig. 11, the removable soleplate F comprises a pivot pin F2. It is then combined with a trail head adapted to slide along a curved axle .l that connects the two endless track trucks C.

For the purpose of firmly connecting together the supports of the gun carriage to the platform constituted by the endless tracks when opened-out fiat and anchored to thev ground, the trucks C and the soleplate F are provided with devices for attaching them to the treads A. For instance, clamping devices may be employed, such as those shown in detail inFigs. 6 and 7. These devices consist ot clamping tongs. Nuts K formed respectively on the soleplate F and on the trucks C serve as supports to hinge pins L of thetjaws M. A screw N provided with a wedgeN1 and adapted to work in the nut K, allows ofV clamping or unclamping at will the jaws M on to or from the guide ribs A1. f

In the example shown in plan in Fig. 8, the soleplate F is attached by means of turnbuckles O to pins P provided in a lodgment of one of the chain treads. As shown in Fig. 9, the soleplate F may also be fixed to the end treads of the opened-out chains by means ot ordinary bolts Q pressing the lugs of the soleplate upon corresponding lugs of thev ribs oi' the treads.

Although the improved endless tracks are more particularly designed for use in constituting a firing platform, they may also serve for anchoring theA chains when the latter are kept coiled in the position for transport. ln such a case the endless track trucksV would of course be.v xed upon the chain treads bymeans of devices such as those shown in Figs. 6 and 7, or any other suitable devices.

Instead of arranging the guides or slides D for the passageand holding of `the stakes or other anchoring devices so as to project laterally on the treads A, they may be arranged at any other Vpoints oi said treads.
