Application October 17, 1957, Serial No. 690,734

4 Claims. (Cl. 33-50) This invention relates to a gunsight adapted for various types of weapons and instruments such as firearms, range finders, testing equipment, cameras, and surveying equipment.

The primary object of the present invention resides in the provision of a novel gunsight having incorporated therein means for simply and accurately adjusting the gunsight for targets at varying distances.

A further object of the present invention resides in the provision of a gunsight having means whereby a sportsman can continue looking at the target through the gunsight while adjusting it for greater or lesser range.

The construction of this invention features a gunsight having mounted therein a reticule slide which is controlled by the position of a rotatable cam which raises or lowers the reticule slide to raise or lower the cross hairs of the slide.

Still further objects and features of this invention reside in the provision of a gunsight that is simple in construction, capable of being easily installed on various conventional weapons, such as firearms and relatively short range, heavy weapons such as mortars or the like, which is capable of being easily adjusted and which has incorporated therein means for indicating to the sportsman peering through the gunsight the precise range to which the gunsight is adjusted.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this gunsight, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a perspective view of one form of the gunsight comprising the present invention;

Figure 2 is an enlarged longitudinal sectional view of the gunsight as taken along the plane of line 22 in Figure 1;

Figure 3 is a transverse sectional view in an enlarged scale as taken along the plane of line 33 in Figure 2;

Figure 4 is an enlarged sectional detail view illustrating the means for adjusting the reticule cross hair indicia and the reticule construction;

Figure 5 is a transverse sectional detail view on an enlarged scale as taken along plane of line 55 in Figure 2;

Figure 6 is an exploded perspective view illustrating the construction of the reticule slide and slide holder;

Figure 7 is an elevational view of a modified form of the invention shown mounted on a portion of a firearm; and

Figure 8 is a sectional detail view in an enlarged scale of the modified form of the invention.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, the reference numeral 10 generally designates the gunsight comprising the pres ent invention, which is adapted to be mounted on a hand weapon, as indicated at 12, or any other suitable appa- 2,913,826 Patented Nov. 24, 1959 ratus by means of mounts such as the brackets indicated at 14 or by any other suitable means. The tube 10 is provided with a threaded end, as at 18, threadedly receiving a lens holder 20 which holds lenses 22 and 24 in position within the elongated tube 26 of the gunsight 10, with the lenses 22 and 24 being held in spaced relationship by means of a lens spacer 28. Another lens 30 is mounted at the opposite end of the tube 26 and held in place by a knurled elevational adjustment ring 32 which is threadedly engaged on the threaded end 34 of an inner hollow cylinder 36 which is received as an inner sleeve within the tube 10 conforming generally to the contours of the tube 10 and which is locked against axial displacement by means of fasteners as are indicated at 38 and 40. Further holding the lens 30 in place is a lens spacer ring 42. It is to be recognized that as the adjusting ring 32 is rotated, the cylinder 36 will likewise be rotated. The cylinder 36 has fixed thereto an elevation cam 44. The elevation cam 44 has an eccentric outer surface 46 which can be best seen in Figure 3. This cam is rotatable with the cylinder 36.

Held in place on the tube 10 is an adjusting face housing 48 which is maintained in the desired position not only by the fastener 38 but by a fastener 50. The fastener 50 also serves to hold a slide holder 54 in position in the tube with other fasteners, such as indicated at 56, also serving to hold the slide holder 54 in place, the fasteners extending through four apertures indicated at 58 in the slide holder 54.

The slide holder 54 has a vertically extending groove 70 therein as well as an aperture 72 therethrough through which the cross hairs 74 of the reticule slide 76 can be observed. The reticule slide 76 is adapted to be constrained to vertical movement only by being seated within the groove 70 and has a projection 72 which is provided with an internally threaded bore 74, through which a threaded adjusting member 76 extends, the adjusting member terminating in a follower 78 adapted to engage the eccentric outer circumferential surface 46 of the cam 44. The threaded portion 76 of the follower has a shaft 80 fixedly attached thereto which is journalled in the adjusting base housing 48 and has an adjusting knob 84 attached thereto. The adjusting knob 84 has a ser rated or toothed surface for enabling the ready rotation thereof and for engagement by a pawl or detent 86 fixed to the housing whereby the adjusting knob 84 is held in an adjusted position by the detent 86. A spring 90 is concentrically disposed about the shaft 80 and biases the follower and the reticule slide downwardly with the follower 78 being resiliently engaged with the cam 44.

Attached to the cam 44 and rotatable therewith is a pointer which cooperates with the indicia, as at 102, which indicia are mounted on members 104, 106, 108 and 110, each of which includes racks 112, 114, 116, and 118. The racks are engaged by gears 120, 122, 124, and 126. The gears are fixed to the fasteners holding the slide holder 54 in place and extending through the apertures 58 and these fasteners terminate in heads which may be rotated to position the indicia 102. Thus, the indicia 102 can be placed adjacent to the cross hairs with the indicator 100 pointing to the indicia representing a certain range.

In use, assuming the gunsight 10 is assembled on the weapon 12 with windage built into the mount, the procedure for adjusting the device for elevation is initiated by adjusting the ring 32 to a zero or point on which a stop mounted on this member and the tube 26 come together. Then, the adjustment knob 84 is rotated until the rifle is sighted in and zeroed on a target at one hundred yards, and at this point indicia are placed on a 'dial, as at 120, and the adjusting knob 84 held in place by the pawl 86. The indicia 102 is then adjusted so that the pointer 104 will point to the indicia 102 having the numeral 1 representing 100 yards. The rifle is then carried back to the 200 yard mark and the ring 32 adjusted until the rifle is zeroed in for this range and a small 2 is placed on the dial 120 at this point. This procedure is subsequently carried out for various increments of ranges; It is to be noted that the extent of adjustment may be controlled by the cam surface 46. As the ring 32 is rotated, the cam surface will lower, causing the follower to be depressed, thus causing a depression of the cross hairs 74 and requiring that the weapon be elevated to maintain the gunsight on the target. By use of the indicia 102, the sportsman or user of this gunsight may readily adjust the gunsight by merely rotating the ring 32 without removing his eye from the sight, and thus maintaining the sight on the target due to the coaction of the pointer and the indicia. It is held that the indicia on the scale 120 cooperates with a pointer 122 mounted on the tube 26. In lieu of this arrangement, the arrangement as is shown in Figures 7 and Scan be provided wherein a knurled knob 140 is mounted within the stock 142 of a weapon and is connected by means of a flexible cable 144 to a gear 146 which is in engagement with another gear 148 mounted on a cylinder 150 to which a cam 44 is attached. The other elements of the invention are identical. In this form of the invention, maintaining his grasp on a stock, the hunter may adjust the scope for range in a convenient and highly eflicient manner.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
