My invention relates to gun sights, and has among its objects and advantages the provision of an improved sight structure designed to permit accurate shooting of moving targets, with the sight structure embodying novel means for setting the sight to adjust the gun with respect to a target moving at a predetermined speed.
In the accompanying drawing:
Figure 1 is a side view partly in section of a sight structure in accordance with my invention;
Figure 2 is a sectional view taken substantially along the line 22 of Figure 1;
Figure 3 is a view taken from the position indicated by line 3--3 of Figure 1;
Figure 4 is a detail view of a sight adjusting cam; and
Figure 5 is a detail sectional View of the connection between the adjustable telescopes and the arms of the means for adjusting said telescopes.
In the embodiment selected for illustration, I make use of a telescope II) which is associated with the gun, such as an antiaircraft gun, cannon or the like. This telescope parallels the axis of the gun. One end of the telescope I0 is supported in a body I2 and its other end is supported by a plate 14 having a tubular neck l6 through which the telescope is extended and fixedly connected.
About the telescope Ill are mounted four telescopes I8. The telescopes l8 are spaced ninety degrees apart circumferentially of the telescope it). One end of each of the telescopes I8 is pivotally connected at 20 with lugs 22 formed on the body [2. About the opposite ends of the tele-; scopes 18 are secured bands 24 pivotally connected at 26 with arms 28 slidable in radial grooves 30 in the plate M.
The arms 28 are provided with teeth 32 meshing with a spiral rib 34 on one face of a cam plate 36. This cam plate is rotatably mounted on the telescope l0 adjacent the plate l4 and is provided with an internal gear 38 meshing with a pinion 40 secured to a control shaft 42. This control shaft is rotatably supported in a bearing 44 in a cover plate 46 secured to the telescope Ill. The other end of the control rod is rotatably supported in the body l2 and is provided with a handwheel 48. This handwheel is provided with a scale 50 graduated in terms of speed, such as miles per hour of the moving target, and coacts with a pointer 52 to indicate the reading position of the scale.
In operation, rotation of the rod 42 imparts rotation to the cam plate 35. Since the cam plate has meshing engagement with the teeth 32 on the arms 28, rotation of the cam plate in one direction imparts simultaneous pivotal motion to the telescopes l8 for increasing their angle with respect to the telescope I0, while rotation in the opposite direction simultaneously moves the telescope l8 for decreasing their angle.
The four telescopes [8 are so arranged as to facilitate adjustment of the gun to targets moving vertically or horizontally in both directions. With a target moving at a predetermined speed, the sight employed for that target is easily set through rotation of the rod 42 to bring the given speed marking on the scale 50 into registration with the pointer 52.
Without further elaboration, the foregoing will so fully illustrate my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
I claim:
1. A gun sight for moving targets comprising a fixed telescope sight, a plurality of telescope sights mounted about said fixed sight, a mount on one end of the fixed sight, means pivotally connecting the corresponding ends of respective adjustable sights with said mount, a guide member secured to the opposite end portion of the fixed sight, a plurality of arms each pivotally secured to a respective one of said adjustable sights and mounted to slide in said guide radially of the fixed sight, and a spiral cam rotatably mounted on the guide concentrically of the fixed telescope sight and engaging the inner end portions of the arms for simultaneously moving the arms and the adjustable sights in respective planes radially of the fixed sight.
2. A gun sight for moving targets comprising a fixed telescope sight, a plurality of telescope sights mounted about said fixed sight, a mount on one end of the fixed sight, means pivotally connecting the corresponding ends of respective adjustable sights with said mount, a guide member secured to the opposite end portion of the fixed sight, a plurality of arms each pivotally secured to a respective one of said adjustable sights and mounted to slide in said guide radially of the fixed sight, a spiral cam rotatably mounted on the guide concentrically of the fixed telescope sight and engaging the inner end portions of the arms for simultaneously moving the arms and the adjustable sights in respective planes radially of the fixed sight, and a speed scale connected to be moved with said spiral cam to indicate the positions of the adjustable sights with respect to the fixed sight for targets moving at predetermined speeds.
