GUN-SIGHT ATTACHMENT.

SPECIFICATION forming part of Letters Patent N o. 638,007, dated November 28, 1899.

Application led February 27,1899. Serial No. 707,048. (No model.)

To @ZZ whom it may concern:

Be it known that I, DEXTER H. DAELING, a citizen of the United States, residing at Guilford, in the county of Chenango and State of New York, have invented a new and useful Gun-Sight Attachment, of which the following is a specification. This invention relates to sighting attachments for rifles and' other ordnance articles;

Io and the object of theinvention is to provide a simple and efficient operating mechanism for quickly adjusting the sight relatively to the gun-barrel and for firmly maintaining the same in its adjusted position and for also insuring the accurate position of the sight relative to the barrel or other part to which it is applied.

The invention involves as one of its features and in combination with a standard which 2o may be secured to the barrel or other part of a gun or other tiring device a sighting member, a carrier for the latter sustained by the standard, and two independent and preferably simultaneously active devices located at oppo- 2 5 site sides of the standard, and each of which is operable for adjusting said carrier and for sustaining the same at opposite sides thereof, whereby the accurate relation between the sight and the gun-barrel is assured in the va- 3o rions adjustments of the sight. In the present case the adjusting devices to which I have referred consist of oppositely-threaded parts, and they are preferably rotary scroll wheels or disks movable withthe sight-carrier and 3 5 each adapted to receive a pin or stud fixed to the standard or other stationary part. By turning either one of these wheels the adj ustment of the sight will follow, and when V`the latter is properly set it will be held in such po- 4o sition by a suitable locking device constituting part of the invention. In addition to securing the accurate positioning of the sight relative to the part to which it is applied the attachment described is particularly adapted to right or left handed shooters, as either can manipulate the most convenient scroll-wheel with his free arm without removing the piece from the shoulder. The sighting attachment may be of any construction, although I prefer 5o to employ a telescope for this purpose.

l/Vith these ends in view the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in whichv Figure 1 is a perspective view of a rifle equipped with my sighting attachment. Fig. 2 is a transverse section taken in the line 2 2, Fig. 1. Fig. 3 is a perspective View of the standard removed from the gun, the sight-carrier, and the adjusting devices for the latter in assembled relation, the sightcarrier being illustrated as adjusted a slight distance above the base-piece of the standard. Fig. 4 is a transverse central section through the same. Fig. 5 is a perspective view of the carrier or block sustaining the sight. Fig. Gis a similar view of the standard for said carrier or block. Fig. 7 is a face view of the scroll-wheels, and Fig. 8 is a perspective View ofthe supportingshaft for said scroll-wheels.

Like characters denote like and corresponding parts in each of the several figures of the drawings.

In the drawings I have represented a rifle R of ordinary construction to which my invention may be applied and which is provided with the usual barrel 2 and the stock 8, the two parts being secured together in some convenient or well-known manner.

As hereinbefore set forth, the sighting attachment may be of any suitable kind, and it is represented herein as consisting of a telescope 4, the length of which exceeds somewhat that of the barreland which is hinged, as at 5, near the front end of the barrel, although the manner of supporting the telescope may be other than that illustrated. The eyepiece of the telescopic sight 4 is 1ocated at a point to the rear of the end of the barrel, and in the present case it is adjusted vertically by raising or loweringsaid telescopic-sight relatively to the barrel.

The sight 4 passes through the opening 6 in the carrier or block C, which is vertically slidable between the upright arms 7 and 8, located at opposite sides of the standard 9 IOO and bifurcated, and between the branches of the bifurcations a supporting shaft or spindle 10 for the carrier C is disposed. The opposite ends of t-he shaft extend outward beyond the upright bifurcated arms 7 and 8 of the standard 9 and carry adjusting devices, hereinafter described, and said shaft extends through the transverse opening 12, formed near the lower side of the sight carrier or block C.

Thetelescopic sight 4 is held in fixed position relative to its carrier by means of setscrews, as 13, passing through the upper side of the carrier, and the lower ends thereof being adapted to engage the periphery or outer surface of the sight. It will be evident that by raising or lowering the carrier or block C the vertical adjustment of the sight relative to the bar'rel will follow.

The under side of the standard 9 is provided with the tongue 14, closely fitting within the correspondingly-shaped groove 15, formed in the plate 16, which can be secured in some suitable manner to the gun-barrel or other part to which the device is applied.

The shaft or spindle 10 is provided upon its projecting ends with the wheels or disks 17 and 18, the iirst-mentioned of which has a right-hand thread 19 in the form of a scroll or spiral upon its inner face, and the wheel 18 is provided with an oppositely-disposed or left-handed thread 20, also in the form of a scroll, and these threads are adapted to cooperate with the pins or studs 2l and 22, fixedl to the opposite sides of the standard, said pins being adapted to project into the grooves or spaces between the two oppositely-disposed threads 19 and 20. The projectingends of the carrier-supporting shaft 10 are provided with keys, as 23, adapted to fit in corresponding keyways 23 of the two scrollwheels 17 and 18, whereby the latter will be held against rotation relative to the shaft which sustains them.

From the preceding description it Will be apparent that by turning the scroll-Wheel 17 to the right or the scroll18 to the left the elevation or depression of the block or carrier C, and consequently of the barrel 2, will follow.

For the purpose of maintaining the parts in their adjusted positions I provide a suitable locking device, as the nut 24, in engagement with the threaded end 25 of the shaft l0, the latter having at its opposite end the stop or shoulder 26, which is adapted to abut against the outer face of the scroll-wheel 18. By turning the nut 24 to the right the scrollwheel 1S, through the stop or shoulder 26, is drawn against the adjacent face of the bifurcated arm 8, while the scroll-wheei 17 is forced against the bifurcated arm 7, thereby firmly locking the parts in the desired position. By turning the nut 24 the parts 17 and 18 may be free to turn, so that the adjustment of the carrier, and consequently of the sight movable therewith, can be obtained.

The locking-nut 24 serves by a very slight turn to either lock or release the scroll-wheels 17 and 18, and it is secured in place by the cheek-nut 27, a washer 28 being disposed between these parts and said check-nut being in threaded engagement with the shaft 10 in proximity to the locking-nut24.

The mechanism described is simple and serves to sustain the carrier, and consequently the sight, in correct position with respect to the gun-barrel or analogous member, and at the same time the adjustment of the sight can be effected with facility and rapidity, while the parts can be maintained in their adjusted positions with rigidity.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrifieing any ofthe advantages of the invention.

I-Iaving thus described theinvention, what I claim is- 1.
