adapts itself to precision production and close tolerances thereby reducing possible mechanical errors to a minimum; which, after adjustment can not he accidentally moved out of adjustment or the adjustment thereof changed without the Referring more specifically to the drawing, the peep sight in its entirety, constituting the invention, is designated generally I and constitutes generally a housing section 8, an outer cylinder 9 and an inner cylinderv Ill.

The housing section I comprises an elongated base II and an integral barrel or cylinder portion 12 which is disposed thereabove and longitudinally thereof and which is provided with a bore I3 of circular cross section and which extends longitudinally therethrough. The base H is provided with an undersurface H which is shown use of a special tool, thus substantially locking the sight in adjustm nt against unauthorized tampering therewith, nd which is capable of being accurately adjusted by a single adjustment for making corrections for elevations and deflec- [\tion or windage.

Still another object of the invention is to provide a substantially enclosed peep sight which will afford a smooth exterior, irrespective of the setting thereof, to thereby obviate any possibility of any of the moving parts of the sight striking an obstruction such as the interior of a saddle boot, a weapons case, clothing or brush, andto provide a sight having no projecting knobs or other extensions capable of catching on obstacles, so that a particular sight setting may be maintained indefinitely and under corresponding conditions of terrain, wind and light, may be utilized at spaced time intervals and with-out requiring resetting of the sight, or only a partial resetting thereof.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a preferred embodiment of the invention, and wherein:

Figure 1 is a side elevational view, partly in longitudinal section showing a preferred embodiment of the improved peep sight;

Figure 2 is a rear elevational view thereof, showing the peep sight applied to a portion of the upper part of a firearm receiver;

Figure 3 is a view similar to Figure 2 but looking toward the forward end of the peep sight;

Figure 4 is a side elevational view, partly in longitudinal section of the inner cylinder of the peep sight;

Figure 5 is a side elevational view of the outer cylinder thereof, and

Figure 6 is an exploded perspective view of the inner and outer cylinders and their connecting elements.

as being concave in cross section to rest flush on the rounded upper side of the receiver or barrel [5 of a rifle or other suitable firearm, not shown. It will be readily apparent that the undersurface l4 could be of various shapes to conform to the contour of the upper surface of any receiver or barrel on which it is adapted to be mounted. The base I I extends beyond the ends'of the barrel or cylinder portion l2 and is provided adjacent each end thereof with an upwardly flared opening It for receiving the flared head of a screw fastening ll each of which extends into a threaded upwardly opening recess 18 in the receiver or barrel 15 for detachably mounting the peep sight I thereon. When the fastenings I! are tightened, the heads thereof will not extend above the upper surface of the base H and said fasteners will cooperate to retain the under surface H of base in flush engagement with the upper surface of the barrel or receiver to thereby securely attach the peep sight 1 thereto. 1

The outer cylinder 9, which is of circular cross section externally, is sized to slidably and rotatably engage in the bore l3 and is provided with an eccentrically disposed bore 19 which extends longitudinally therethrough and which the inner cylinder I0 is sized and shaped to 's'lidably and rotatably engage. The outer cylinder 9 is provided with a diametrically disposed bore 20 formed in the thickened portion thereof and adjacent the forward end of said cylinder 9 and which has an inner end opening into the bore I9 and an outer end which opens outwardly of the periphery of said cylinder to receive a pin II which is of a length greater than that of the bore 20. The cylinders 9 and III are of approximately the same length and when the cylinder I0 is applied to the bore l8 and with the ends thereof disposed flush with the ends of the cylinder 9, the inner end of the pin 2| will seat in a portion of an annular, outwardly opening groove or channel 22 of the inner cylinder l0 for rotatably connecting said cylinders 9 and I0.

As best seen: in Figure 1, the barrel or cylinder portion 12 is provided with an annular groove or channel 23 which opens inwardly into the bore I3 thereof and said barrel I2 is provided with a longitudinally disposed, inwardly opening groove 24 having an inner end communicating with the annular groove 23 and an outer end opening outwardly of the forward end of said cylinder portion I 2. The outer end of the pin 2| projects beyond the periphery of the outer cylinder 9, when the inner end thereof is seated in the groove 22, said outer end is adapted to be received in the groove 24 for permitting the connected cylinders 9 and ill to be inserted into the bore l3 through the forward end of said cylinder or barrel l2 and so that said outer end of the pin 2| may thus bemoved into engagement with the groove 23, so that by rotation of the cylinders 9 and i0, said cylinders will be rotatably engaged with the barrel l2. Thus it will be readily apparent that the ends of the pin 2| will be retained in engagement with the grooves 22 and 23 so as to turnably and non-slidably mount the cylinder 9 in the housing 8 and the cylinder ID in said cylinder 9.

The inner cylinder I is provided with an eccentrically disposed peep sight bore 25 which extends longitudinally therethrough and which is provided with a restricted portion 26, disposed contiguous with the groove 22 thereof.

As best seen in Figure 3, the forward end of the cylinder 9 is provided with spaced tool receiving recesses or sockets 21 and the complementary end of the cylinder I0 is provided with a single tool receiving recess or socket 28, which is diametrically spaced from its bore 25.

The opposite end of the cylinder 9 is provided with circumferentially spaced, longitudinally extending slots 29, each of which opens into the bore l9 and outwardly of the periphery of said cylinder 9 and each of which extends to the rear end of the cylinder, as best illustrated in Figure 6. The base portion of the housing section 8 and adjacent portion of the barrel part l2 thereof are provided, on opposite sides of said section 8, with inwardly extending threaded bores 30, formed by drilling transversely through the section 8 and internally threading the ends of thedrilled bore. The upper part of the intermediate portion of the drilled bore opens into the bore I3, as seen at 3|. adapted to receive an Allen type set screw 32 having a conical inner end 33, received in the complementary bore portion 3| and which, when advanced, extends into the bore l3 for clamping engagement with the cylinder 9 for fixedly securing said cylinder against rotation within the bore l3. The set screws 32 also compress the slotted end of the cylinder 9 for clampingv the inner cylinder ID within the bore l9 and against rotation relatively thereto.

Assuming that the peep sight 1 is applied and assembled in the manner as previously described, and as illustrated in the drawings, and that the cylinders 9 and ID are arranged, as seen in Figures'2 and 3, corrections in elevation and/or deflection may be made by moving the peep sight bore 25 relatively to the housing section 8 by rotating the inner cylinder l0 within the bore l9 sufiiciently to move bore 25 the desired and necessary distance from the center of bore l3, after slightly loosening set screws 32, and then rotating the cylinders as a unit within bore l3 sufficiently to move the bore 25 to the desired and necessary direction from the center of bore l3, after further loosening set screws 32. The set screws 32 are loosened or tightened with a con- Each threaded portion 30 is 4 ventional Allen type wrench, not shown, and a special wrench, not shown, provided with two prongs, one of which engages eachof the sockets 21, may be employed for turning the cylinder 9 in the bore l3, and another two-prong wrench, having prongs arranged to engage the socket 28 and the bore 25, and which may constitute the opposite end of the aforementioned pronged wrench, may be employed for turning the inner cylinder [0 in the cylinder 9 for accomplishing the vertical or transverse displacement of the peep sight bore 25 from its central position of Figures 2 and 3.

It will thus be readily apparent that a peep sight of extremely simple construction is provided having no knobs or other projections capable of catching on clothing, brush, saddle boots or the like, and which is capable of being readily adjusted to compensate for elevations or deflections and which may be clamped in adjusted position so that the setting of the sight can not be tampered with or varied without the use of a special tool.

Various modifications and changes are contemplated and may obviously be resorted to, with out departing from the spirit and scope of the invention as hereinafter defined by the appended claims.
