4 Claims.

This invention relates to improvements in adjustable peep-sights for iirearms.

One object of this invention is to provide an improved adjustable peep-sight for firearms adapted to provide different size peep-sight openings while maintaining, with certainty, a constant single axis of the various size sight-openings.

Another object of this invention is to provide an improved adjustable peep-sight adapted to be adjusted smoothly and continuously from the largestjo...thesmallestsiaaQLQpengi/ade versa, without the necessity of any sudden variations in sizes of openings.

Another object of this invention is to provide an improved peep-sight formed of simple elements readily manufactured and readily assembled to produce a durable efcient construction at minimum cost.

With the above and other objects in view, this invention includes all improvements over the prior art which are disclosed in this application.

In the accompanying drawings, in which one way of carrying out the invention is shown for illustrative purposes:

Fig. 4 is a view similar to Fig. 3, but with the flange of one of the cup-like operating-disks also in section, the iris-leaves and other parts being in elevation;

Fig. 5 is a View similar to Fig. 4, but with the sight adjusted to maximum open position;

Fig. 10 is a perspective view of one of the operating-disks;

Fig. 11 is a perspective view of the other operating-disk; and

Fig. 12 is a perspective View of one of the irisleaves.

In the description and claims, the various parts are identified by specific names for convenience,

but they are intended to be as generic in their application as the prior art will permit.

Referring to the drawings, the firearm-receiver 20 has a sight-support, generally designated by the numeral 2|, and upstanding from one side of 5 the firearm-receiver as indicated in Fig. 1. Carried by the sight-support 2| is a cross-bar 22, in which is adjustably mounted a cross-slide 23 having an internally-threaded opening 24. The peep-sight 25 includes a body-member 26 includ- 10 ing a boss 21 and an externally-threaded tubular stem 28, which threadedly engages in the threaded opening 24, with the stop-shoulder 29 of the boss 21 engaged against the cross-bar 22. The body-member 26 and the tubular stem 28 15 have a sight-passage or sight-opening 30 extending therethrough and the body-member has anl enlarged annular flange 3| provided with diagonally- opposite slots 32 and 33.

34 is a peep-sight assembled unit consisting of 20 two intertting, shallow, cup-like operating- disks 35 and 36 with six leaves 31 forming an iris and located between the disks 35 and 36. The disk 35 has a central sight-aperture or opening 38 and six operating-slots 39 extending through the disk. 25 The disk 36 has a central sight-aperture or opening 40 and six operating-slots 4I extending through the disk. The disk 36 also has two diagonally-opposite arcuate slots 42 and 43.

It will be noted that the slots 4l of disk 36 are 30 approximately radial, while the slots 39 of the disk 35 are arranged approximately at right angles to radial and to the slots 4l. Each iris-leaf 31 (Fig. 12) is formed of thin sheet-metal of elongated form and has one end 44 bent trans- 35 versely approximately at right angles to the body of the leaf, and has the other end 45 bent transversely of the body in the opposite direction approximately at right angles to the body of the leaf and approximately at right angles to the 40 other bent end 44.

In forming the peep-sight unit 34, six leaves may be placed in the disk 36 with the bent ends 44 of the leaves extending through the operatingopenings or slots 4I and with the bent ends 45 45 arranged in position to register with operatingopenings or slots 39 of disk 35. Thereupon, the disk 35 is brought into position to cause the slots 39 to engage over the bent ends 45 and with the annular flange 46 of disk 35 fitting within 50 the annular flange 41 of disk 36, and with the lugs 48 and 49 (occupying their dotted-line positions 48a, 49a) of disk 35 extending through the arcuate slots 42 and 43, whereupon the lugs 48 and 49 are bent from their dotted-line positions 55 i EMU! 48a and 49a to their full- line positions 48 and 49, thus holding the two disks 35 and 36 and the six leaves 31 all assembled together as a unit. The assembled unit can then be assembled in the complete peep-sight by engaging the lugs 50, 5| of the disk 36 in the slots 32, 33 in the flange 3| of the body-member 26. The operating-ring 52 preferably has its outer surface knurled and is provided with interior slots 53, 54 and a sightaperture or opening 55. The operating-ring 52 is assembled over the flange 3| of the bodymember 26 and rotated until the slots 53 and 54 engage with the lugs 48 and 49 of disk 35. Or, the unit 34 can be assembled in the peep-sight in reverse position with the lugs 50, 5| in the slots 53, 54 and with the lugs 48, 49 in the slots 32, 33. The surface 56 of the operating-ring engages against the end face of ange 3| to limit the telescopic engagement of the parts 52 and 3| to form a bearing surface for the relative rotation of them. The annular edge 51 of the operatingring 52 is spun or flanged over into Contact with the chamfered surface 58 of the body-member 26 to hold parts 52 and 26 in assembled rotary relation.

When the operating-ring 52 is rotated anticlockwise, the iris-leaves are caused to swing toward the axis of the sight-opening to provide the smallest opening to which the sight can be adjusted', such, for example, as is illustrated in Figs. 2, 3, and 4. When the operating-ring 52 is rotated clockwise, the leaves 3l are caused to swing outwardly away from the axis of the sightopening to their maximum open position, such as illustrated in Fig. 5.

It will thus be seen that a peep-sight constructed in accordance with this invention permits of readily varying the sight-opening slowly or quickly and continuously to any desired size of opening within its range of adjustment, and without shifting the axis of the opening. In other words, this sight can be adjusted from the smallest to the largest opening while the person is looking through the sight, and without obstructing sight through the sight-passage.

The device may be made of any suitable materials and the disks and leaves will preferably be made of non-rusting material, such, for example, as sheet-brass or other suitable non-rusting sheet-material. An embodiment of the peepsight illustrated in the drawings has been constructed with the operating-ring of outside diameter and with the leaves made of sheetmetal having a thickness of between .005 and .006". This peep-sight can be adjusted to give a sight-opening considerably smaller than gli" diameter.

The invention may be carried out in other specic ways than that herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiment is therefore to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
