Definitions
- the invention relates to a reticule for a telescopic gun sight ixedly carried by a gun to move -bodily with the gun barrel, and while said reticule is disclosed for an elbow sight of a 37 mm. antiaircraft gun, the projectiles of which have a muzzle velocity of 2700 foot seconds, it could well be calibrated for sights other than elbow types and for guns other than anti-aircraft types regardless of calibre and projectile velocity.

13 Claims.
The invention relates to a reticule for a telescopic gun sight ixedly carried by a gun to move -bodily with the gun barrel, and while said reticule is disclosed for an elbow sight of a 37 mm. antiaircraft gun, the projectiles of which have a muzzle velocity of 2700 foot seconds, it could well be calibrated for sights other than elbow types and for guns other than anti-aircraft types regardless of calibre and projectile velocity. The sight in which the disclosed reticule is to be used, has a field of 24 and a magnication of 2, and as there are 6400 artillery mils in 360, approximately 427 mils would be covered by the sight in question. However, the invention is not restricted to use with a sight having any particular magniiication nor any p-articular field but may be calibrated for proper functioning in any telescopic sight.
The principal object of the invention is to ,pro-` vide a new and improved reticule which will permit the gunner to quickly, easily and accurately lay the gun on the target, which is of paramount importance for anti-aircraft and similar firing.
A further object is to provide a reticule on which the target may be simply spotted to visually determine the range of said target.
A still further object is to make novel provision for showing when the gun is properly elevated for the determined range.
Yet another object is to make novel provision for showing when the gun has been given approximately the proper lead on the target, the speed of which may be judged by the gunner or determined in the usual way.
The invention is calibrated for maximum accuracy when the target is traveling horizontally at right angles to the axis of the sight and gun barrel, and the experienced gunner may readily make allowances for targets not traveling in this precise manner.
With the above and other objects in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.
Fig. lis an elevation on an enlarged scale showing one form of the reticule.
Fig. 2 is another elevation on an enlarged scale showing a diiferent form of the reticule.
Both forms of the reticule will be specifically described, with the understanding however, that Variations may be made within the scope of the invention as claimed.
In Fig. 1, the numeral 5 denotes the transparent disk or panel of the reticule for association with the other optical elements of a telescopic sight in the same manner in which the usual reticule is associated with said elements.
The disk or panel 5 is inscribed with a plurality of equally spaced vertical sight lines 6, 1 and 8 all disposed below the reticule center or axis 9 and equally distributed to the right and left of said center or axis', said lines being spaced apart ve artillery mils in the present disclosure. The lower ends of the lines 6, 'l and 8 preferably terminate as shown for use in laying the gun on a target at a range of 9,750 feet, and the locations of the upper ends of said lines are preferably as described below.
The lines 6 may be considered as one set. They extend to one height and are uniformly spaced from each other. The distance between any one of these lines 6 and the next line 6, is the length of the image which a target of known size will cast on the reticule at a known range. In the present disclosure, a target length of twenty-five feet is assumed and the lines 6 are so spaced that if the image of said target can be subtended between any one of these lines 6 and the next line 6, just spanning the space between these lines, this fact visually determines` that the target is at a range of 1250 feet. The upper ends of the linesl 6 are so located as to constitute sighting points which visually determine when the gun has been adjusted to the proper elevation for the range of 1250 feet. The lower ends of some of the lines 6 and B are numbered to indicate target speeds in miles per hour for use in determining lead. After determining the target speed, if said speed be 100 M. P. H. for example, the gun is so traversed that the line marked 100 (at the side of the sight axis on which the target is traveling) can be used as a sighting line to give the approximate lead for the 100 M. P. H. target and 1250 foot range. Thus when ring at a range of 1250 feet at a target traveling 100 M. P. H., the gun is so traversed and elevated that the tar-get image appears over the 100 M. P. H. line and even with the upper ends of the 1250 foot range lines 6, thereby laying the gun properly in advance of and above the target to effect a hit.
The lines l, constituting another set, are used in the same way as the lines 6 but they are uniformly spaced apart lesser distances and extend to lesser heights, for visually determining a range of 2500 feet and the necessary elevation for this range.
The lines 8 are used for a range of 5000 feet and in determining this range, the target image is subtended between any one of these lines 8 and the next line 1.
As the required lead varies not only with target speed but with range and distance of the target from the gun axis, the target speed numbers at the lower ends of some of the lines 6 and B necessarily give only approximate leads, and the gunner with the aid of the tracers with which the projectiles are equipped, is enabled to make required corrections.
The Vertical center of the reticule is marked by a line I0 and short horizontal lines II preferably extend across said line I0 for use when ring under diving targets.
In Fig. 2, the transparent panel or disk I2 has inscribed thereon a plurality of horizontal rows or sets of horizontally spaced lines, only the three uppermost rows or sets being given reference characters (I3, I 4 and I5). All of the rows of lines are below the reticule center or axis I6 and extend to the right and left of said center or axis. The lines I'I in the upper row I3 are of the same length as the image which a known-size target (twenty-five feet in the present disclosure) will cast upon the reticule at a range of 1250 feet, and the spaces I8 between these lines are of the same length. Thus, if the target image can be so located on the reticule as to match the length of any line Il, or the space between any line I'I and the next line I1, it is known that the target is at a range of 1250 feet. The row I3 is located at such a height that placing of the image on said row will attain proper elevation for the 1250 foot range.
The lines and spaces in the row I4 perform the same functions as the lines Il and spaces I8 of row I3, but for a range of 2500 feet; the lines and spaces of the row I5 act in the same Way for a range of 3750 feet; and the lines and spaces of the other rows are used for other ranges.
For determining approximate leads, for various target speeds, curved substantially vertical lines I9 are provided having numbers representing miles per hour.
A vertical line 20 extends through the axis I6 and short horizontal lines 2| preferably cross said line for use when ring under diving targets.
From the foregoing taken in connection with the accompanying drawings, it will be seen that I have made novel provision for attaining the desired end of permitting the gunner to quickly, easily and accurately lay the gun on the target, and while preferred details have been disclosed, attention is again invited to the possibility of making variations, within the scope of the invention as claimed.
While both reticules have been described for use against 25 foot targets, it is obvious that they may also be used in firing upon targets of other sizes. For example, either reticule could well be used against a 50 foot target, as said 50 foot target would span two spaces instead of one, and targets of varying sizes between 25 and 50 feet could be fired upon by taking into account the amount of space spanned thereby.
