Description
OC. 17, 1937 G. C. LUEBKEMAN BINOCULAR FRONT SIGHT Filed Aug. 25, 1965 y United States Patent O 3,346,962 BINOCULAR FRONT SIGHT George C. Luebkeman, 11S Mount Nebo Road, Cieves, Ohio 45002 Filed Aug. 25, 1965, Ser. No. 482,520 6 Claims. (Cl. 33-52) This invention relates to gun sights and is particularly directed to a novel means for varying the apparent color of a gun sight that is specifically adapted for use in the binocular method of aiming a gun, or the like.
The general subject lma'tter of this invention is disclosed in a co-pending application, Ser. No. 339,530, lfiled Jan. 22, 1964, of myself and John R. Miles for Binocular Front Sight for Firearms.
It is very often desirable to change the apparent color of the front sight of a gun used in binocular shooting in order that the sight may be readily distinguished frorn the surrounding terrain and/ or sky whereby the sight will be more attractive to the aiming eye of the shooter whilst being less attractive to the non-aiming eye and thus improve the image of the binocular sight in a particular situation. These changes are frequently desired in the field where tools are scarce and there is little time for ,f a change-over and hence my invention also encompasses 1' a relatively simple; adjustable means for changing the apparent color of a binocular front sight.
My invention therefore has for its principal object the provision of a simplified, self contained Imeans for varying the apparent color of a binocular front sight, when required in the field, without the necessity of removing the entire sight from the gun barrel.
Another object of the invention is to provide an improved binocular front sight for firearm that is capable of transmitting an attractive color into the restricted sighting area for the aiming eye of the gun user properly positioned for shooting at a target and also transmitting to the non-aiming eye a color similar to the circumambient hues of the terrain and/or sky.
It is a further object of the invention to provide a self contained means for varying the two apparent colors transmitted by a binocular gun sight having the characteristics of the next preceding object of this invention.
These and other objects of the invention will be apparent from the following specification taken in conjunction with the accompanying drawings forming a part hereof and wherein like reference characters indicate similar parts throughout the several views.
In the drawings:
FIG. 1 is a fragmental, top plan view of a shot gun barrel with one form of my gun sight positioned thereon.
FIG. 2 is an enlarged, fragmental section taken on line 2-2 of FIG. 1.
FIG. 3 is a fragmental section like FIG. 2 showing a modification of the gun sight depicted in FIGS. 1 and 2 of the drawings.
FIG. 4 is a section taken on line 4-4 of FIG. 3.
FIG. 5 is a fragmental section similar to FIG. 2 of the drawings illustrating another modication of my gun sight.
FIGS. 6 and 7 are sections showing other forms for the rotatable element of the gun sights illustrated in FIGS. 3-5 of the drawings.
Referring now to FIGS. 1 and 2 of the drawings the numeral indicates, by way of example, the barrel of a single barrelled shot gun provided with the usual sighting rib 16 on its upper side. The muzzle end 17 of the barrel is provided with one form of my binocular front sight 18, the breach end 19 of the barrel being mounted in the usual manner on a suitable stock 20. A laterally restricted sighting area 21 is located above the gun stock in longitudinal alignment with the gun barrel whereby ICC the aiming eye 22 must be located by the gun user, properly employing binocular aiming techniques, within said sighting area.
The gun sight 18 comprises a sleeve member 23 that is preferably cylindrical in configuration and which has a cut-out portion 24 in its upper central part, said cut-out portion being at least large enough to admit a headed mounting screw 25 therethrough. The shank 26 of the screw extends through a hole 27 formed in the bottom of the sleeve member and is threaded in a tapped bore 28 in the muzzle end of the gun rib 16. A generally cylindrical body member 29 of a suitable transparent material having a good index of refraction is positioned within the sleeve, said body member having an hemispherically curved end 30 which confronts the breach end of the gun and extends through the rear opening in the sleeve member 23. As best shown in FIG. 2 a flat 31 is ground in the bottom of the body member in order that the member may be inserted through the breach end of the sleeve, clear the headed mounting screw 25 and be firmly anchored in the sleeve by means of a pin 32 extending through the sleeve wall and into the body member 29. The muzzle end 33 of the body member terminates short of the open forward end of the sleeve, said forward end of the sleeve being provided with internal threads 34 into which is threaded a spot carrying member in the form of a plug 35, said plug being tightened in the sleeve by means of a tool that is received in a slot 36. A minute spot of color 37 is carried by the plug 35 and it will be noted, with reference to FIG. 2, that the hemispherically shaped end 30 of the body member 29 forms a convex lens and that the spot of color 37 is in the focal center of the lens whereby rays of light from the spot of color 37 will pass through the body member and be transmitted as substantially parallel rays 38 toward the breach end of the gun barrel and the laterally restricted sighting area 21 therefor.
In operation, when the spot 37 is colored red, for example, the light rays 38 of the same color will be apparent to the aiming eye 22 of the shooter provided said eye is properly positioned for binocular aiming of the gun, the non-aiming eye 39 being unattracted by the red color of the gun sight. Depending upon the color of the sky and the surrounding terrain the shooter may wish to change the color emitted from the front sight for observation by the aiming eye and to this end a plurality of plugs 35 may be provided each carrying a differently colored spot and each interchangeable in the sight sleeve member 23. In the instance of the device shown in FIGS. 1 and 2 it is only necessary to carry a number of the spot carrying members or plugs 35 on the person, the sight color being changed by unscrewing one spot carrying plug from the sleeve and inserting therein a spot carrying plug having the desired colored spot.
With reference to FIGS. 3 and 4 of the drawings which illustrate a modified form of my binocular front sight the interchangeable spot carrying member comprises a block 40 mounted for rotation on its vertical axis and which is substantially square in section and has opposed end trunnions 41 and 42 formed integral thereon, each trunnion being longitudinally movable in a slot 43 and 44, respectively, formed in the front portion of the sleeve 23. The upper trunnion 41 is elongated somewhat and has fixed to its end an operating knob 45 which has a knurled circular side wall 46 that may be manually grasped to rotate the member 40 on its trunions in the slots. A sinuous leaf spring 47 exerts resilient pressure against the rotatable member 40 and is mounted within the sleeve in any suitable manner, as by anchoring the spring ends in detents 48 formed in opposed portions of the interior wall of the sleeve 23. A translucent dust guard 49 closes the muzzle end of the sleeve and may be mounted thereon in any suitable manner as by means of adhesive, or the like.
The plural, faces on the rotatable member each carry a differently colored, minute spot 50 which may be inserted in the faces and are successively positioned aaginst the rear face 33 of the transparent body member 29 by turning the knob the spring 47 being adapted to urge the rotatable member toward the face 33 yof the body member and thus position each spot in the focal center of the body member and against said face and also permit rotation of the member 40 whilst its trunnions move longitudinally in their respective slots.
In FIG. 5 there is shown another modieation of my invention wherein the rotatable member 51 has an irregular form in section and is provided at its lower end with an externally threaded shank 52 which is threaded in a tapped bore 53 in the sleeve 23 of the sight. The upper end of the rotatable member 51 is connected to a shaft 54 which freely projects through an opening 55 formed in the sleeve, the upper end of the shaft having a suitable tool receiving slot 56 therein. A leaf spring 57 is anchored in the sleeve 23 and has its free end bearing against the member 51 in order to hold the member in angularly adjusted positions. The rotatable member has a plurality of faces each carrying a minute colored spot 58 that will each be adapted to be positioned in the focus of the hemispherical face on the breach end of the transparent body member 29 of the front sight.
As illustrated in FIGS. 6 and 7 of the drawings, the rotatable members 40 and 51 depicted in FIGS. 3-5 of the drawings may have other irregular forms such as the flat form 59 shown in FIG. 7 wherein spots 60 and 61 of different colors are disposed on its two major faces or the member may have a triangular configuration in section like that shown at 62 whereby each of its three major faces may carry one of three different colored spots 63, 64 and 65.
In all my gun sight forms described heretofore only the sight images produced in the aiming eye of the shooter using binocular sight have been described. The peripheral color surrounding the minute spot will now be described, this peripheral color being generally the color observed by the non-aiming eye Eof the shooter.
With reference to the form of my invention shown in FIGS. l and 2 of the drawing, it is contemplated that the interchangeable spot carrying plug members 35 may be composed `of opaque or translucent materials as the requirements of the sight may dictate and it is further thought that the inner faces of the members 35 which confront the rear face 33 of the body member 29 may have an over all black, white or other color applied thereto to surround the contrasting color of the spot 37. Thus, by way of example, for night shooting the overall inner surface of the spot carrying plug could be colored black whilst the minute spot could have a white color whereby the aiming eye of the gun user would see the sight as the color white whilst the non-aiming eye would not be attracted to the sight because its image would blend with the dark or black color of the night.
Now with reference to the modification of my invention shown in FIG. 5 it will be further noted that the rotation of the member 50 will cause the spots 58 thereon to move vertically with respect to the body member 29. This vertical movement 4of the spots will result in the movement ofthe sighting area 21 in a vertical direction so that the binocular sighting position of the gun may be adjusted vertically to fit the individual requirements of the gun user. When a square spot carrying element is used and all the spots have the same color each quarter turn of the spot carrying element would represent the minimum quarter thread, vertical adjustment whilst the use of the fiat or triangular spot carrying members will have different angular degrees of spot adjustments, as will be readily apparent to those skilled in the art.
