Rangefinder and aiming device.

Patented in the German Empire from April 8th, 888.

The present. Invention is based on the difference in the visible height of one People at different distances and consists of connection and arrangement of the parts described below.

Fig. I, 2, 3 and 4 show the combined Range and aiming device attached to an ordinary rifle and connected used with an ordinary grain.

B is a small telescope with lenses of ordinary construction. C are flexible plates which are attached to the telescope walls at c ^{, while the other ends c 1 of} these plates are bent at right angles so that their edges, between which the target object can be seen, are parallel and horizontal.

D and E are swing arms that support and guide the telescope; they are rotatably attached to the rifle stock and dimensioned so that they secure the direction of the telescope axis with the front sight at all degrees of elevation. The upper ends d of the arms D protrude like a crank and are connected by f to the sleeve F sliding on the telescope. The lower ends of the arms D are mounted on a spindle d ¹ on which a pointer ^ ^{2 is} attached. A graduation d ^s is affixed to the rifle stock to indicate the distance.

G is a set screw that sits in the sleeve F and the bracket H and rests against the upper flexible plate C ; part g ^{1 of} this screw has a thread which is twice as steep as that on part g . The rimmed head g · ^{4 of} the screw is divided and has a pointer g ¹ for its adjustment. The screw conveniently passes through a slot g ^s in the telescope.

H is a bracket that is guided by screw G and fixed pin h; the latter goes through a slot h ¹ in the telescope into the hole h ^{2 of} the sleeve F. This bracket rests on the lower side of the lower plate C. By turning the screw G , the edges c ^{1 of} the flexible plates can be set closer or farther from one another, the combined action of the screw G and the bracket H making that both edges c ¹ always project the same distance from the telescope axis. The distance between the edges c ¹ is automatically adjusted by the levers D, according to the different distances, which by means of the joints f move the sleeve F on the telescope, so that when the sleeve is pushed further away from the objective glass, the edges c ^{1 of} the plates are brought closer to each other, and vice versa.

The curve of the plates C is so dimensioned that at every elevation of the telescope (in order to correspond to the different distances) the distance between the edges c ^{1 of} the plates C corresponds exactly to the visible height of a man at a depth corresponding to that elevation.

The second adjustment made possible by screw G has the purpose of adjusting the position of the plates according to the different heights (at

same gun width) of cavalry or artillery, standing, kneeling or lying down Regulate infantry as indicated in FIGS. 5, 6, 7 and 8.

In this embodiment of the invention, the adjusting screw G is adjusted depending on the object (cavalry, infantry, etc.) aimed at, and the telescope is then raised or lowered until the object that appears fits exactly between the plate edges c ^1. The rifle is now set and aimed at the same time and will be fired in the usual manner.

/ is a springy protection that is attached to the seeing end of the telescope and against the forehead of the target end is placed around his eye when kicking back against damage to protect.

J is a chamber mounted in the rifle stock, in which the telescope rests when not in use and which can be closed by a slide j. In cases where such a hollowing out of the shaft does not seem desirable, the telescope can be designed to be detachable. The spindle d ¹ can be equipped with a clamping screw so that the telescope can be locked in any desired elevation.

9, 10 and 11 show the determination the part of the invention belonging to the distances on an ordinary two-pipe Binoculars attached. In these figures there is a modification of the means of adjustment of the plates. The sleeve is omitted here, so that only the adjusting screw is used, although in some cases the sleeve is also used on the binoculars and can be adjusted by hand with a screw.

In these designs, as before, flexible plates C with brackets and adjusting screws are used ", but instead of the edged head of the latter, small toothed wheels K and L are attached which engage in an intermediate wheel M , which is loosely on the pin attached to the binoculars m can rotate. the wheel K is provided with a circular Scala and with numbers that indicate the distances in which the visible height of cavalry in those distances straight c between the plate edges ¹ hineinpafst. Rad L likewise has a circular, with numbers provided Scala for standing infantry while wheel M is equipped with double Scala and pay for kneeling and lying infantry. on the binoculars are the pointer km ¹ I attached to the distances to be easily read.

Using this embodiment of the apparatus, it is pointed at the object in the usual way and the distance between the plate edges c ¹ is adjusted by one of the toothed wheels up to the point at which the visible object just fits between the plate edges. The digit of the relevant scale which corresponds to the object in this position will indicate the width of the arm.

Of course, the invention described here in connection with handguns can also be used with artillery weapons of all kinds.

Claims (2)

Patent Claims: 1. Arrangement of a range finder based on the difference in the visible height of a person at different distances, simultaneously serving as a target device, formed by two flexible plates CC , bent at right angles at the front, with parallel edges being attached to a telescope or two-tube binoculars c ¹ by moving one over the respectively. the tubes of the glass pushed sleeve F so long by. or pushed against each other until the space between the edges c ¹ coincides with the height of the target object at the scope or distance corresponding to the telescope or binocular elevation. 2. The rotatable arrangement and connection of the telescope or binoculars on BEZW. with a firearm through the swing arms D and E, of which the arms D are connected by intermediate joints with the sleeve F , in order to move the latter by raising and lowering the glass for setting the distance of the edges c ^l corresponding to the image of the target object.
