Vorrichtung zum Einschießen von Gewehren. Patentiert im Deutschen Reiche vom 31. Dezember 1910 ab. Device for aiming rifles. Patented in the German Empire on December 31, 1910.

Gegenstand der Erfindung ist eine Vorrichtung zum Einschießen von Gewehren, bei der das Gewehr im wesentlichen unter denselben Bedingungen abgefeuert wird wie beim freihändigen Schießen. Das einzuschießende Gewehr wird in der Nähe seines Schwerpunktes von einer gabelförmigen Stütze umfaßt, deren untere Enden in Längsführungen des Schießgestells zurückgleiten können und deren Gewichtsverteilung eine solche ist, daß der Schwerpunkt der Gabel mit dem Schwerpunkt des Gewehres zusammenfällt. Durch veränderliche Zusatzgewichte kann der Schwerpunkt der¹ Stütze entsprechend der Schwerpunktslage der verschiedenen einzuschießenden Gewehre, verändert werden.The subject of the invention is a device for aiming rifles in which the rifle is fired under essentially the same conditions as in hands-free shooting. The rifle to be shot is surrounded in the vicinity of its center of gravity by a fork-shaped support, the lower ends of which can slide back in longitudinal guides of the shooting frame and whose weight distribution is such that the center of gravity of the fork coincides with the center of gravity of the rifle. With variable additional weights, the center of gravity of the ¹ support can be changed according to the center of gravity of the various rifles to be shot.

Das Kolbenende des Gewehres ist frei in einem rechteckigen Ausschnitt des Schießgestells gelagert, so daß das Gewehr beim Schuß frei zurückgleiten kann und wie beim gewöhnlichen Schießen nur durch die Muskelkraft des Schießenden gehalten wird.The butt end of the rifle is free in a rectangular cutout of the shooting frame stored so that the rifle can slide back freely when firing and as with Ordinary shooting is held only by the muscular strength of the shooter.

Da durch das Anbringen der Stütze die Schwerpunktslage des Gewehres nicht verändert wird, so bleibt auch das durch den Rückstoß auf das Gewehr ausgeübte Drehmoment unverändert, und die Abweichung des Schusses infolge dieses Drehmomentes ist genau dieselbe wie beim gewöhnlichen Schießen.Since attaching the support does not change the center of gravity of the rifle the torque exerted by the recoil on the rifle remains unchanged, and the deviation of the shot due to this torque is exactly the same like ordinary shooting.

Auf der Zeichnung zeigt Fig. 1 eine Seitenansicht der Vorrichtung mit dem einzuschießenden Gewehr, Fig. 2 einen Grundriß, Fig. 3 eine Hinteransicht, Fig. 4 einen Längsschnitt nach M-N der Fig. 2, Fig. 5 einen Querschnitt nach P-O der Fig. 2 und in etwas größerem Maßstäbe und Fig. 6 bis 8 Einzelheiten.1 shows a side view of the device with the rifle to be inserted, FIG. 2 shows a plan view, FIG. 3 shows a rear view, FIG. 4 shows a longitudinal section according to MN of FIG. 2, FIG. 5 shows a cross section according to PO of FIG. 2 and on a slightly larger scale and FIGS. 6 to 8 details.

Die Vorrichtung besteht aus einem tischartigen, auf vier Füßen ruhenden Ständer, dessen Unterteil einen oben offenen Kasten bildet, welcher zum Zweck größerer Stabilität mit Sand gefüllt werden soll, aus der auf der Tischplatte des Ständers befindlichen Einstellvorrichtung, welche dem einzuschießenden Gewehr einerseits die richtige Lage sichern, andererseits die genaue Zielrichtung geben soll, und aus einer Art Gewehrstütze der oben näher gekennzeichneten Art.The device consists of a table-like stand resting on four feet, whose lower part forms a box open at the top, which for the purpose of greater stability is to be filled with sand, from the adjustment device located on the table top of the stand, which, on the one hand, ensure the correct position of the rifle to be shot, on the other hand the exact aiming should give, and from a kind of rifle support the above closer marked art.

Die Gewehrstütze besteht aus einem elastisch sich ausspreizenden, U-förmig gestalteten Bügel i. Da dieser das Gewehr fest und unverrückbar mit seinem Krümmungsbogen an der Stelle umklammern soll, an der sich der Visierfuß des Gewehres befindet, so sind an den inneren Wandflächen der beiden Schenkel des Bügels zwei einander gegenüberliegende Ansatzstücke 2 derart angenietet, daß sie sich mit ihren hervorragenden Seitenflächen an die Seitenrippen des Gewehrschaftes und die Seitenränder des Visierfußes dicht anlegen, sobald die beiden Schenkel zusammengedrückt und in dieser gespannten Form durch Einschieben des mit Nuten versehenen Schließdeckels 3 festgehalten werden. Auf beiden Schenkeln des Bügels sind zwei auswärts gespreizte Füße 4 befestigt, deren gegenseitiger Abstand durch Einsetzen der Querspreize 5 bestimmt wird. Unterhalb dieser Spreize sind an beiden Außenflächen der Füße 4 zwei nachThe rifle support consists of an elastically spreading, U-shaped Bracket i. Since this the rifle firmly and immovable with its curvature should clasp the place where the rifle's sight base is located, are on the inner wall surfaces of the two legs of the bracket two opposite one another Attachments 2 riveted so that they are with their outstanding side surfaces to the Place the side ribs of the rifle stock and the side edges of the sight base tightly as soon as the two legs pressed together and in this tensioned form by pushing of the grooved closing cover 3 are held. On both legs of the temple there are two outwardly spread Feet 4 attached, the mutual distance of which is determined by inserting the cross brace 5. Below this strut are on both outer surfaces of the feet 4 two after

outside protruding, hemispherical rounded pins 6 attached, which in degree guides of the shooting frame.

On the closing cover 3 there is a loading disk 7 which, for the purposes indicated above, is intended to coincide the center of gravity of the support with the center of gravity of the rifle. The size of the weight of the loading disk is determined empirically and, depending on the position of the center of gravity of the rifle to be inserted, is changed by additional weights or the like.
A rifle provided with the rifle support described is immediately given a completely stable position when it is placed on a horizontal table top in such a way that, in addition to the two support points offered by the rifle support, it is supported on some third point of the lower part of its butt. If the rifle is set up on any horizontal platform so that its piston protrudes more or less over the edge of the platform, it changes its angle of inclination by pushing it forwards or backwards as a result of the inclined direction of the lower part of the piston without losing its stability.
An iron base plate 9 rests on the horizontal table top 8 of the stand. On the transverse strips 10, which are riveted to the base plate at a certain distance, rests a sleeper plate 11, the ribs of which are turned upwards and therefore form a parallel, flat path, in which a straight sliding of the foot ends of the rifle support 4 takes place in the vertical target plane of the rifle. The correct height of the rifle in this plane is achieved in that the obliquely inclined lower part of its piston is loosely inserted into a right-angled cutout 12 of the crosspiece 13. In order to enable the direction of destination to be changed in the horizontal plane, the upper threshold plate has a vertical pivot pin 14 around which it can be pivoted by means of two adjusting screws 15.

In the slideway of the top plate, a transverse sleeper 16 is longitudinally displaceable by means of a screw spindle 19, which serves as a stop for the rifle support when it is moved forward. This enables the rifle to be pushed in quickly and precisely to a certain altitude. To compensate for any inclined position of the rifle, which would cause the sight to tilt, the cross vial 26 for horizontal adjustment of the slideway is attached to the flat bottom surface of the upper threshold plate in the vicinity of its pivot point. In addition, a special spirit level is used to check the horizontal position of the sight comb of each rifle to be shot, which is inserted through the opening 27 in the side walls of the rifle support bracket so that it can rest freely with its base on the upper surface of the sight base. This vial is pushed in by simultaneously raising one foot and lowering the other foot of the rifle support, which can be achieved by means of a screw spindle 29 by means of a transverse displacement of a plate 28 lying on the bottom of the slide, the lateral edges of which are wedge-shaped ( Fig. 8).

When using the device, it is particularly important to ensure that each Rifle firmly and immovably at the relevant point in the opening of the The bracket of the rifle support is jammed. With regard to the not exactly the same The size of the rifle stock must be a certain extension of the height of the opening of the hanger have, which is filled by inserting semicircular wedges 31 (Fig. 1), whereby a tight tightening of the touching surfaces is made possible.
