To all whom it may concern:
Be it known that I, Max BARTHOLDY, residing at Essen, Germany, a citizen of the German Republic, have invented certain new anduseful Improvements in Sighting Devices, of which the following is a specification.
This invention relates to sighting devices which are mounted on a member which takes part in the elevation movement of the gun barrel, and are provided with an arrangement for allowing for influences which, such as erosion of the gun barrel for example, may cause a variation in the normal range of the gun. The object of the invention is to provide for such arrangement a construction which shall be as simple as possible and therefore most useful for'military purposes.
The invention will be described with reference to the accompanying drawings, which show two constructions of the present invention.

Fig. 5 is a section on the line 55 of Fig. 4 looking from the left.
Figs. 6 to 13 relate to the second construction of sighting device, and of these,
Fig. 6 is a side elevation corresponding to Fig. 1,
Fig. 7 is a plan view corresponding to Fig. 6 partially in section,
Fig. 8 is a view corresponding to Fig. 6 with certain parts in another position,
Fig. 9 is the right-hand end view corresponding to Fig. 6, partially in section, on the line 9-9 of this figure.
Figs. 10 to 13 are sections on the lines 1010, 1111, 1212, and 1313 of Fig. 8.
The first construction will be described first.
Referring to the drawings, on the slide carrier A, which is constructed as an annular body and in which the gun barrel is guided in the usual way, there is mounted parallel with the axis of the horizontal trunnions a a pin a by means of an arm a rigidly attached to the slide carrier. On this pin a are pivotally mounted two rods B and C situated opposite to each other, the lower rod 13 carrying on its free end an attachment bar B which is sector-shaped and curved concentrically with the axis of the pin a and is guided in an attachment sleeve a mounted on the slide carrier A, while the upper bar C carries a sighting telescope C which determines the direction of the sighting line. The attachment bar B is adjusted to the angle which corresponds to the range of the target by means of an adjusting pinion D, which is mounted in the attachment sleeve a and provided with a milled head -(Z and engages with a series of teeth Z2 on the attachment bar B On the attachment sleeve a is also provided a bar a (see Figs. 1 and 3) provided with a range graduation a, the corresponding reading-0H mark Z2 being placed on the attachment bar 13 On the lower bar B are provided two lugs E rigidly connected thereto, which} are arranged like a fork, as shown in the drawings, and between which a rocking lever F is adjustably mounted on two pins 0 and 0 This rocking lever F has in it a slot 7 curved as the arc of a circle, in which is guided a sliding piece G which consists of two parts connected together by a pivot bolt 9 This sliding piece G is connected by the pivot bolt g to one end of a connecting rod H, the other end of which is connected by a pivot bolt 0 to the upper bar C. To the connecting rod H is attached a second connecting rod J, the other end of which is connected by means of the arm (1,2 to the slide carrier A. The length of the connect ing rod H is equal to the radius of curvature of the slot f in the rocking lever F, so thatthis latter, as shown in Figs. 1 and 4:, can be brought into an angular position with respect to the bar B, in which its axis of curvature coincides with the axis of rotation of the pivot bolt 0 The arrangement is also so contrived that when the bars B and C and the rocking lever F are in the position shown in Figs. 1 and 4, in which, on the one hand, the sighting line of the sighting telescope C is parallel with the longitudinal axis of the gun barrel; and on the other hand, the axis of curvature of the rocking lever F coincides with the axis of rotation of the pin 0 the axis of oscillation (the axis of the pins 6 and c of the rocking lever F coincides with the axis of the pin 9 The rocking lever F is adjusted by means of a worm K, which is provided with an operating device and is mounted on the lower end of the lug E and engages with a series of worm teeth f on the rocking lever F arranged sectorwise. The angular position imparted to the rocking lever F by means of the operating-device k is read off by means of a mark m (see Figs. 1 and 3), which is situated on a disk M pivotally connected to the rocking lever F by a spur wheel gearing m f (see Figs. 4 and 5), and is opposite an angle graduation e which is situated on a part 6 (see Fig. 5) rigidly attached to one of the lugs E.
The description of the working of the sighting device will be commenced when the position of the parts are as shown in Figs. 1 and at, in which position the sighting telescope is set to the Zero of the range of the target and the rocking lever F is secured with respect to the rod B in that position in which its axis of curvature coincides with the axis of rotation of the pivot bolt c. When using the sighting device, the attachment bar B is adjusted to the elevation corresponding to the range of the target by rotating the milled head al This adjustment of the attachment bar B is taken up by the bar C, which rotates about the same axis because it is pivotally connected with the attachment bar B by the gearing members F G H J. The connecting rod J also rotates the connecting rod H in the direction of the arrow as (see Fig. 1) about the axis of the pivot pin 0 the sliding piece G changing its position in the slot f in the rocking lever F. 'As, however, the axis of curvature of the recess 7 coincides with the axis of rotation of the pin 0 when the rocking lever F is in the position stated, the gearing members J G g F cause no change in the angular adjustment imparted to the bar C by means of the gearing D 6 The bar C, and consequently also the telescope G which determines the direction of the sighting line, always rotates therefore when the rocking lever F is in the angular position stated, through the same angle as the attachment bar B If, however, the initial velocity of the projectiles has become lessened by erosion of the gun barrel for example, the rocking lever F is rotated by means of the operating device 717 in the direction of the arrow 2 (see Fig. 3), until the mark m is opposite the division mark of the graduation which corresponds to the diminished initial Velocity. The result of this is that the gearing J H G g F augments the angle of adjustment imparted to the sighting telescope C by means of the gearing D 6 by an amount which corresponds to the diminished initial velocity. When the sighting telescope is adjusted to the angle corresponding to the zero of the range of the target, this amount is itself equal to Zero, as the axis of oscillation of the rocking lever F coincides, when the attachment bar B is adjusted to correspond to the zero of the range of the target, With the axis of the pivot pin 9 and increases with the increasing angle of adjustment.
The special advantage of the sighting device described, consists in the fact that the gearing which is provided for allowing for the influence of the diminished initial velocity, is of a simple construction and therefore useful for military purposes, and in which any particular curved surfaces which are difiicult to make are avoided, and the use of ordinary attachment sighting devices is rendered possible without further alterations.
The second constructional of the present invention shown in Figs. 6 to 13, is distinguished by the fact that in the arrangement for allowing for the influences which may be brought about by a change in the normal range of the gun, the wear of the several moving parts is reduced to a minimum.
The arrangement of the bar B with the attachment bar B and the bar C with the sighting telescope C is, apart from a few constructional details which are unimportant in so far as this invention is concerned, the same as in the first construction of the present invention and need not therefore be more fully described. It need only be mentioned that the range graduation 71* is not arranged, as in the first construction. on a member (a fixed to the slide carrier A, but on the attachment bar, and the reading-off mark a cooperating therewith is correspondingly arranged on the attachment sleeve at. Furthermore, the rocking lever F, with its slot f and the sliding piece G guided therein, is arranged, as in the first construction, between two lugs 7r corresponding to the lugs E, and is pivotally mounted on the bar B by means of two pins c and c. This sliding piece G is also connected to the bar C by a connecting rod of the above given length. The pivot bolts which serve to connect the connecting rod H with the sliding piece G and the bar C, are likewise denoted by g and c as in the first construction.
Whereas, however, in the first constructional example the rocking lever F can be secured in different angular positions with respect to the lugs E on the bar B by means of worm gearing, in the second construction it is adapted to rotate relatively to the lugs b on the bar B which correspond to the lugs E, when the bar B is adjusted and is positively guided by means of the connecting rod which is composed of three parts J J 2 as. GEGMETREGAL lNSTRUiVliEF-l'ltfi.
and J 3 which can be adjusted relatively to each other. This connecting rod J J J is, like the connecting rod J of the first construction, connected to the slide carrier A, but is not attached, as in the first constructional example, to the connecting rod H, but to the rocking lever F. In order that the positive action of the adjusting apparatus may not be lost by the movement of the rock lever F when the sighting device is being adjusted, there is mounted on the said rocking lever a self-locking worm L, which is provided with a milled head and gears into a series of teeth g on the sliding piece G, and by means of which the said sliding piece G can be secured in various angular positions in the recess 7. The adjustment imparted to the sliding piece G is read off by means of a pointer 9 (see Figs. 8 and 12), which is connected to the sliding piece by a pin 9 (see Fig 12), and is situated opposite a graduation 7 (see Fig. 8) arranged on the rocking lever F. A slot f (see Fig. 8) is provided in the rocking lever for the pin 9 The connecting rod J J J 3 is attached to the slide carrier by a sleeve of, which consists of a bolt N (see Fig. 10) and acts as a pivot pin for the connecting rod. The bolt N can be moved in straight guides 72 (see Figs. 6, 8 and 10) which are provided for the stem of the bolt, and a square head al (see Fig. 10) on the bolt in a plate P. The sleeve n bears against this plate P, and also against a nut n screwed onto the bolt N, so that the bolt can be secured relatively to the plate P by tightening up the nut 01*. The plate P is adapted to move at right angles to the longitudinal direction of the guides p on a plate R attached to the slide carrier A. For this purpose guide slots 29 are provided in the plate P for bolts S which engage in the plate R- with a square head 8 (see Fig. 10) and carry nuts 6 by means of which the plate P can be secured relatively to the plate R. This arrangement enables the bolts N to be adjusted in different parallel positions to each other. Furthermore, for the purpose of making the connectingrod J J J adjustable in length, the part J 3 thereof, which embraces the parts J and J 2 thereof like a sleeve, is provided with longitudinal slots i (see Figs. 6 and 8) for bolts T (see particularly Fig. 11), which bolts T are passed through apertures in the parts J and J of the connecting rod, and carry a head t (see Fig. 11) and a nut The description of the working of the sighting device will be commenced when the position of the parts are as shown in Fig. 6, in which the telescope C is adjusted to the zero of the range graduation, and the rocking lever F and the sliding piece G are situated in that position in which the axis of curvature of the guide f coincides with the axis of the pivot bolt 0 and the axis of the pins 6 and 6 with the axis of the bolt 9 When using the sighting device, the attachment bar B is adjusted to the elevation which corresponds with the range of the tar get, by rotating the milled head 6Z1. This adjustment of the attachment bar is taken up by the bar C which rotates with it about the axis of the pin a since the axes of the bolts and of the pins 6 and 6 cannot alter the above described relative position, and in such a way that it itself rotates and consequently with it also the telescope C relatively to the slide carrier through the same angle as the attachment bar B When this takes place, the connecting rod J J J oscillates on the sleeve n and the bolt N respectively in the direction of the arrow :0 (see Fig. 6), and the rocking lever F oscillates relatively to the bar B in the direction of the arrow z (see Fig. 6).
If, however, the initial velocity of the pro jectile has been diminished say by erosion of the barrel of the gun for example, the guide piece G is moved by the gearing L g in the guide 7' in the direction of the arrow 2 (see Fig. 6), until the pointer g is opposite the graduation mark of the graduation 7 which corresponds to the diminished initial velocity (see Fig. 8). The axis of the bolt g then no longer coincides with the axis of the pins (2 and 6 the result of which is that the gearing F G g H J J J augments the angular adjustment imparted to the sighting telescope C when the attachment bar B is adjusted by an amount which corresponds to the diminished initial velocity. When the sighting telescope is adjusted to the angle corresponding to the zero of the range graduation, this amount is itself equal to zero as the axis of curvature of the guide f coincides with the axis of the bolt 0 when the attachment bar 13 is adjusted to correspond to the zero of the range graduation, and increases with the increasing angle of adjustment.
In comparison with the apparatus of the first construction, the apparatus just described offers the advantage that the gearing which is provided for making allowance for the influence of the diminished initial velocity, only executes oscillating movements when the sighting telescope has been adjusted. In consequence thereof the wear and tear of this gearing is reduced to a minimum, and a permanently accurate adjust ment of the sighting device insured.
If the trajectory of the projectile be altered by the use of another projectile or another propelling charge, the bolt N and the length of the connecting rod J J J is adjusted when the parts B C H F G are in the position shown in Fig. 6, in a suitable manner by the aid of the above described arrangement, and in particular and conveniently by means of scales and marks which are provided on the corresponding parts.
