Semen 30am 1935. F. L. HUMESTON SIGHT FOR FIREARMS Filed Feb. 20, 1934 Patented Sept. 17, 1935 UNITED STATES Search Rccm PATENT OFFICE SIGHT FOR FIREARMS Maryland Application February 20, 1934., Serial No. 712,149
5 Claims. (01. 33-56) This invention relates to an improvement in firearm-sights and particularly to adjustable rear sights for firearms, though not so limited.
One of the objects of the present invention is to provide a simple and reliable firearm-sight which may be readily and conveniently adjusted.
A further object is to provide a superior adjustable firearm-sight characterized by simplicity of construction and economy of manufacture.
Another object is to provide a simple, reliable and rugged sight which may be adjusted to compensate for so-called windage, as well as for socalled elevation.
Other objects and advantages will appear to those skilled in the art from the following, considered in conjunction with the accompanying drawing and the appended claims.
In the accompanying drawing:
Fig 1 is a broken top or plan view of the rear portion of a firearm-barrel, showing a rear sight embodying the present invention mounted thereon;
Fig. 2 is a view thereof in side elevation;
Fig. 3 is a transverse sectional view taken on the line 3--3 of Fig. 2;
Fig. 4 is a transverse sectional View taken on the line 4-4 of Fig. 2;
Fig. 5 is a perspective view of the elevatingscrew, detached;
Fig. 6 is a similar view of the elevating-screw operating-head;
Fig. 7 is a similar view of the sight-carrier; and
Fig. 8 is a similar view of the sight-base.
The embodiment herein chosen for the illustration of the present invention includes a sightbase generaily designated by the numeral ID, preferably formed of spring material, such as properly-tempered sheet-metal, and including a rearwardly-extending flexible arm ll having its rear end upwardly offset as at [2 and having each of its respective opposite sides adjacent its forward end formed with downwardly-and-inwardlybent opposed fingers l3-l3 embracing a fillerplate M. The filler-plate [4 just referred to is provided with a central recess into which is pressed as at l6l6 a portion of the respective inner ends of the fingers 13-43, as clearly indicated in Fig. 3. The fingers l3l3 and the fillerplate l4, when assembled together as shown, provide a transversely-extending dovetail-lug ll for driving fit into a transverse dovetail-groove I8 formed in the upper surface of the firearm-barrel l9 or other suitable member of the firearm.
The upwardly-offset portion I2 of the flexible arm H of the sight-base I0 is formed adjacent its rear end with a perforation having its inner end chamfered or countersunk and receiving the rivet-like shank 2| of a tubular pivot or bushing 22. The said bushing 22 is provided with a threaded axial bore 23, an overhanging head 24 5 and an annular bearing-portion 25, which latter is of lesser diameter than the said head-portion 24 and of greater diameter than the shank 2! before referred to.
Mounted upon the bearing-portion 25 of the tubular pivot or bushing 22 between the under face of the head 24 and the upper face of the offset-portion I2 of the sightbase I0, is a springlike sight-carrier 26 preferably formed of suitablytempered sheet-steel and generally conforming to the shape of the flexible arm ll of the sightbase. The said sight-carrier is provided with a perforation 27 receiving the bearing-portion 25 of the bushing 22, and includes also an integral upwardly-bent sight-finger 28 having a horizontallyarranged internally-threaded sight-aperture 29 which may itself be utilized as a peep-sight, or if desired may receive the externally-threaded shank 36 of an interchangeable peep-sight disk 3| having a usual sight-aperture 32 arranged coaxially 25 of the shank and hence coaxially of the said sight-aperture 29 of the sight-carrier 26.
The forward end of the sight-carrier 26 is beveled as at 33 and is suitably indented to provide a downwardly-offset detent-projection or rib 34 adapted to fit in any one of a series of troughlike indented graduations 35 formed in the upper surface of the sight-base I0 and extending beneath the adjacent end of the sight-carrier 26, which latter is suitably tensioned so as to cause the detent-projection 34 to yieldingly engage with any one of the indented graduations 35 to releasably hold the sight-carrier 26 in a selected one of a variety of positions of lateral adjustment.
Projecting upwardly into the threaded bore 23 of the tubular pivot 22 is an elevating-screw 36 having a non-cylindrical shank 3'1 extending into and riveted over in a similarly-shaped perforation 38 (Fig. 6) of an operating-head 39 having its periphery serrated as at 40 or otherwise suitably roughened to provide a convenient fingergrip.
The edge portion of the operating-head 39 is downwardly offset as at 4.! and is formed in its under face with a plurality of substantially-radial grooves or notch-like recesses 42 into which extends the curved upper surface of the barrel I9 to a degree sufficient to yieldingly restrain the said operating-head 39, and the adjusting-screw 55 of which it forms a part, against accidental turning movement.
When it is desired to change the elevation of the sight-aperture 29 or of the sight-aperture of a peep-sight disk mounted therein, the elevatingscrew 36 may be rotated for the purpose referred to by means of the serrated periphery of its operating-head 39, it being understood that the tension of the flexible arm II is always exerted downwardly to maintain the under face of the operating-head 39 in engagement with the periphery of the barrel I 9 or other appropriate member of the firearm.
In the event that it is desired to compensate for the deflecting effect of wind upon the projectile, the sight-carrier 26 may be swung laterally about the tubular pivot 22, so as to shift its detent-projection 34 into the desired one of the indented graduations 35 as conditions may require, the tension of the sight-carrier 26 itself being such as to yieldingly maintain the said detent-projection 34 in engagement with the selected one of the indented graduations 35.
From the foregoing it will be seen that the adjusting-means is of a simple and rugged character and that the spring-tension of the sight-base itself will serve to engage the under face of the operating-head 39 with the upper surface of the barrel I!) or such other element of the firearm as may be desired, and thus automatically prevent the accidental rotation of the elevating-screw 36 and the consequent unintentional changing of the elevation of the sight.
By employing a tubular pivot or bushing such as 22 and engaging the elevating-screw or equiv- ,alent member therewith, not only is superior ruggedness secured, but a marked economy of manufacture is effected.
The invention may be carried out in other specific 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.
I claim:
1. In a firearm, the combination with the barment substantially coaxially with respect to the said pivot.
3. A firearm-sight including in combination: I
a sight-base; a laterally-swinging sight-carrier; a hollow interiorly-threaded pivot securing the said sight-carrier to the said sight-base with capacity for lateral swinging movement with respect thereto; and a rotary elevating-screw threaded into the said hollow interiorlythreaded pivot.
4. A firearm-sight including in combination: a sight-base; a laterally-swinging sight-carrier; a hollow interiorly-threaded pivot securing the said sight-carrier to the said sight-base with oapacity for lateral swinging movement with respect thereto; and a rotary elevating-screw threaded into the said hollow interiorly-threaded pivot, and having an offsetting operating-head provided in its under face with a plurality of recesses or grooves for releasable engagement with an interfitting member of a firearm structure.
5. A firearm-sight including in combination: a flexible sight-base having means adjacent one end for attachment to a firearm structure; a laterally-swinging sight-carrier; a pivot securing the said sight-carrier to the said sight-base with capacity for lateral swinging movement with respect thereto; and a rotary elevating-member for vertically flexing the said sight-base and :mounted for engagement with and turning movement substantially coaxially with respect to the said pivot.
