LOADING DEVICE FOR PORTABLE GUNS.

Specification of Letters Patent.

Patented Oct 1, 1912.

To all whom it may concern:

Be it known that I, ALFRED KASTNER, a subject of the Emperor of Germany, and a resident of Essen-on-the-Ruhr, Germany, have invented certain new and useful Improvements in Loading Devices for Portable Guns, of which the following is a specification.

The subject of the present invention constitutes a loading device for those portable guns, the barrels of which are adjustable laterally, relatively to the undermount.

The purpose of the invention is to so arrange the loading device that the ammunition can be presented in line with the axis of the bore, even when the gun barrel has been swung to one side on the mount. This purpose is attained, according to the invention, by having the loading tray, intended to receive the ammunition, shiftable in a guide on its carrier that is arranged upon the mount, the said guide being concentric with the vertical axis about which the gun barrel swings in its lateral adjustment.

One embodiment of the present invention is shown, by way of illustratlon, in the accompanying drawings, in which- Figure 1 is a side view of the loading device and the parts of a portable gun therewith concerned; Fig. 2 is a top plan view of the parts shown in Fig. 1, adjusted to another position; Fig. 3 is a section on the line 3-3 of Fig. 2, on a larger scale; Fig. 4 is a section on the line 44 of Fig. 3, seen from the left; Fig. 5 is a top plan view of Fig. 3, partly in section, and with the loading tray omitted; Fig. 6 is a section on the line 6-6 of Fig. 5; and Fig. 7 is a section on the line 7-7 of Fig. 3, seen from the right.

The gun barrel A is guided upon the slidetrack carrier P, which is swingingly mounted through the medium of horizontal trunnions p in the upper-mount The uppermount R is supported on the undermount B and is adapted to swing thereon about the axis of a vertical trunnion 7", a bearing 5 for which is provided in the undermount.

. For swinging the upper-mount R relatively to the undermount B, a suitable training mechanism (not shown in the drawing) will be introduced between the upper and under mounts. Furthermore, it will be assumed that a suitable elevating mechanism (not shown) will be introduced between the upv per-mount R and the slide-track carrier P, through the medium of which the slidetrack carrier is swung about the axis of the horizontal trunnions p. The training means can be of any desired construction.

The loading apparatus is as follows Upon each of the two cheeks of the under mount B and upon the bearings 6 (Figs. 1

and 2) are jointed a pair of links 0. The axes of the bearings 12 are perpendicular to the vertical plane of the longitudinal axis of the gun. Each pair of links C has jointed connection with a frame D. Upon the frame D is secured a table S, upon which a slide E is movably guided. With the slide E, the loading tray F, which serves to receive the ammunition T (Fig. l) is removahly connected. Each pair of links C constitute together with the appurtenant cheek of the undermount B and the appurtenant frame D, a jointed parallelogram. Each of the frames D has two difierent lengthed perpendicular legs cl and 0Z through which it rests in the laid-over position of the loading device (compare broken line position in Fig. l and full line position in Fig. 2) upon yielding abutments 6 (Fig. 1) which are arranged upon the inclined cover plate B (l ig. 2) of the undermount. For guiding the slide E upon the table S, a claw 6 serves, which is provided on the side of the slide presented toward the gun barrel and extends over the entire breadth of the slide; also a pair of claws 6 mounted on the side of the slide away from the gun barrel. The claws e and e grip the corresponding edges of the table S and are guided upon. these edges. The abutting vertical guiding surfaces of the aforesaid guiding parts are curved on an arc whose center coincides with theaxis of the trunnion 1", when the loading device assumes the loading position indicated in full lines in Fig. 1. For reducing friction between the table S and the slide E, rollers G are provided which are journaled in the housing e mounted upon the slide E. The table S has two abutments s and 8 (Figs. 4t and 5) which limit the movement of the slide E upon the table S.

The upper walls of the roller housings e are curved (Figs. 4 and 7) and designed to carry the loading tray F. For connecting side of the slide E which is turned toward the gun barrel A, is a claw e beneath which a corresponding claw f on the loading tray F can engage (Fig. 3). Furthermore, the slide E is provided on its side presented away from the gun barrel with two hooked-shaped projections e (Figs. 3 to 5). With these projections, a broad nose is of a bolt K (Figs. 4 and 7) can enter into engagement, this bolt being mounted in a housing f on the under side of the loading tray F and acted upon by a spring The projections e are provided with bevelse, which act upon the corresponding incline 70 of the nose k of the bolt K and press the latter into the housing f when the loading tray F is placed upon the slide E. Between the projections e and upon a bolt i resting in these projections, is mounted a weighted lever J. This lever is provided with a spur tooth 71 (Figs. 3 and, 5) which can enter into engagement with seats 8 (Figs. 3, 5 and 7) which is provided in the table S. To each of the rests s corres ends a division mark of an angle scale 8* Fig.5) which is located upon the table S. The pointer belonging to the scale s, is provied by the longitudinal edge c (Fig. 5) of the slide E. The lever J carries a finger 2', by means of which the nose 7a of the bolt K can be thrown out of en gagement with the projections e", by throwing the lever J. Secured to a flange of the loading tray F is an annularbufier f (Figs. 1 and 2) of rubber or the like. Through the medium of this buffer, the loading tray abuts against the breech of the gun barrel, when the loading device is swung into the loading position. At the base of the loading tray, there are two keepers 7 (Figs. 1 and 2) for the carrying bars N (Fig. 2).

Previous to loading the gun, the loading device assumes the position shown in Fig. 2. After the nose 70 of the bolt K has been moved out of engagement with the projection 0 of the slide E, through the lifting of the hand lever J acting through the medium of the finger 71 the loading tray is lifted from the slide. The ammunition is then brought to the gun upon the loading tray and the loading tray is again placed in position upon the slide E, the claws f and 6 being brought into engagement with each other. If the loading tray is now pressed downward, the bolt K is pressed backward by the impingement of its inclined face 76 with the inclined face 6 of the projections e and is then brought into the locking engagement with the projections e, by means of its spring 70 In case the gun barrel, which has been brought into loading position previous to loading, for example, by means of the elevating mechanism, has been swung laterally from its intermediate position, the loading tray, together with the own weight back to the position in which its tooth i engages in one of the seats 8 Finally, the loading device is. swung through the medium of the bars N, toward the gun barrel. When the loading tray abuts against the breech of the gun barrel, through the medium'of the bufi'er f (Fig.

1) it is suddenly arrested, while the ammunition T, in consequence of its developed inertia, slides partially into the chamber of the gun barrel. After the ammunition has been completely introduced, through the medium of a rammer, the loading device is again thrown back.
