Application filed March 20, 1911.

Serial No. 615,604.

To all whom it may concern:

Be it known that I, ARTHUR A. GERMAN, a citizen of the United States, and a resident of Duluth, in the county of St. Louis and State of Minnesota, have invented a new and Improved Gun-Sight, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide an attachment for the peep sight of a gun adapted for rapid and easy adjustment for changing the size of the opening and to provide a construction for an attachment of the character named which is simple and durable.

One embodiment of the present invention is disclosed in the structure'illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a perspective view of a fragment of the stock of a rifle having mounted thereon a peep sight provided with an attachment constructed and arranged in accordance with the present invention; Fig. 2 is a vertical longitudinal section of a peep sight having an attachment constructed and arranged in accordance with the present invention; Fig. 3 is a detail view showing the movable standard and target of a peep sight constructed in the usual manner and having mounted thereon a graduated sight opening plate constructed and arranged as per the present invention; Fig. 4 is a detail view, in perspective, of the pivoted standard of a peep sight; and Fig. 5 is a cross section taken on the line 55 in Fig. 2.

As shown in the accompanying drawings, the pivoted standard is constructed in the manner usual with gun sights of this character having the split sections 11, 11, the core pitch screw threaded section 12, and the hinge disk 13. The disk 13 as is usual in sights of this character is held between the ears 14, 14 set up from the base of the plate 15. Through the ears and hinge disk is extended a pivot shaft 16 about which is closely wound the spring for raising the standard to the vertical position.

Slidably mounted within the standard 10 is a movable standard 17. The standard 17 has provided on the sides thereof rack tooth sections 18, 18. The sections 18, 18 extend between the split sections 11, 11, the same forming guides for the travel of the said standard 17. Mounted rigidly on the upper end of the standard 17 is a cupped target disk 19. The target disk 19 is provided with an annular flange 20 through a slotted perforation in the side whereof is extended a stop plate 21.

The plate 21 is constructed in accordance with the present invention and is pivotally mounted by means of the pivot pin 22 upon the target disk 19. The plate 21 is provided with a series of graduated perforations 23, 24, 25, 26, 27, 28. The perforations 23 to 28 inclusive are gradually enlarged from a point opening to an opening as large as the peep openings 29 and 30 formed in the center of the target disks 19 and 31 respectively.

The plate 21 is provided with a series of peripheral recesses 32, 32 adapted to receive the bent end 33 of the spring 34. The spring 34 is designed to hold the plate 21 in fixed position when either of the perforations 23 to 28 inclusive is concentric with the openings 29 and 30 and to center the said perforations with the said openings. The spring 34 is extended through a slot formed in the flange 20 as shown best in Fig. 3 of the drawings. It is held in the slot by the disk 31 which is provided with a flange 35 to extend over and enfold the flange 20 of the disk 19, forming thereby a hollow casing in which the major portion of the plate 21 is contained. The peep sight thus constructed is raised and lowered by means of a knurled sleeve 36. The sleeve 36 is internally threaded to register with the teeth on the sections 18. The sleeve 36 is held in position by the beading 37 formed at the upper end of each section 11 of the standard 10 and by the lock nut 38 which is internally threaded to register with and be engaged by the threaded section 12 formed on the sections 11, as shown best in Fig. 2 of the drawings.

When in operation the nut 38 is manipulated to release the sleeve 36. The said sleeve may be manipulated to raise and lower the standard 17, the section 18 being tooth engaged with the threads on each side of the sleeve. When the target formed by the disks 19 and 31 and the plate 21 has been elevated or disposed to accommodate the conditions under which the sight is being used, the nut 38 is manipulated to engage the sleeve 86 to clamp the same into fixed position, thereby holding rigidly and fixedly the target.

With a gun sight so constructed, the operation is as follows: The height of the center of the target having been fixed by manipulating the sleeve 36 and nut 38, the gunner, by engaging the edge of the plate 21 extended beyond the flange 20 as shown best in Fig. 3, moves the plate to present any one of the graduated perforations 23 to 28 inclusive in line with the openings 29 and 30 and concentric with the target formed by the disks 19 and 31. The condition of the prevailing light dictates the use of the particular perforation which shall be used. The distance at which the mark is removed also influences and controls the use of the particular perforation adjusted. By means of stopping down the size of the opening through which the forward sight is viewed, a finer and closer adjustment of the sight mark is permitted, this being necessary and possible in accordance with the distance of the mark and the condition of light.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is A gun sight comprising a target provided with double walls to form a box-like structure, said walls having each a sight.

opening in the center thereof; a stop plate pivotally mounted between the walls of said target to extend beyond the edge thereof, said stop plate being provided with a series of size graduated perforations adapted to register with the center of said sight openings, said stop plate being provided with a series of rounded recesses formed in the periphery thereof; and a spring mounted between the walls of said target having a head adapted to bear against the opposite walls of said recesses to move the said plate to register the said perforations with said sight openings said head being arranged to ride out of said recesses in both directions.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
