N. 805,776. PATENTED NOV. 28, 1905. J. Y. BASSELL & I'. C. BLBNKNER. lGUN SIGHT.




Specification of Letters Patent.

Patented Nov. 28,1905.

Application led May 23, 1904:. Serial No. 209,250.

To all whont it puny concern,.-

Be it known that we, JoHN Y. BAssELL and FRED C. BLENKNER, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Gun- Sights, of which the following is a specification. A

Our invention relates to a new and useful improvement in gun-sights.

The object of our invention is to provide a combined open and globe or ring sight.

Another object resides in interchangeable reversible sight-pieces'.

Still another feature is the provision of a reflector which may be folded down and out of the way and which when extended lies at such an angle as to concentrate the rays on the sight-point, thus illuminating the same.

Another feature is embodied in the nesting of the globes or rings, whereby dierent sizes the differing visual needs of shooters and which will ybe strong, durable, and efcient and comparatively simple and inexpensive to make and one in which the several parts will not be liable to get out of working order.

With the above and other objects in view the invention consists of the novel details of construction andoperation, a preferable embodiment of which is described in the specivouter ring in its raised position.

Fig. 7 is a transverse sectional view taken on the line y y of Fig. 2. Fig. 8 is a longitudinal sectional view, the parts occupying the positions indicated in Fig. 5. Fig'. 9 isa transverse sectional view taken on line r fr of Fig. 5. Fig. 10 is a transverse sectional View taken on line s s of Fig. 6. Fig. y11 is a longitudinal'sectional view taken on line z .e of Fig. 3. Fig. 12 is a longitudinal sectional view taken on line H of Fig. 1. Fig.f13 is a detailed elevation of the sight-piece equipped with a squir- Irel-center. Fig. 14 isasimilar view equipped With a pin-head center. Fig. 15 isa like view equipped with a jack-center. Fig. 16 is a longitudinal sectional view on line u 'a of Fig. 1, and Fig. 17 is a side elevation of the sightpiece shown in Fig. 13.

In the drawings the numeral 1 designates the base-block, which is suitablyshaped to be readily attached to the gun-barrel and which may be provided with any suitable form of wind-gage. The base-block is formedwith a transverse groove 2, into which the sightpiece 3 is ladapted to fit. The sight-piece `3 is formed with a central stem 4, upon the upper end of which may be mounted any suitable form of sight head or center, as will be hereinafter described. Notches 5 are formed in each end of the sight-piece, which are engaged by the screw-bolt 6 and the sliding lockbolt 7. The base-block 1 is formed with a` rearwardly-extending portion 8, which houses the bolts` 6 and 7. The bolt 7 is provided with a milled head v9, by which it may be drawn out ofy engagement with the sight-piece 3, thereby allowing the same to be moved out of the groove 2. A shouldered head 10, formed on the bolt 7, acts as a stop to limit the outward movement ofY the locking-bolt by impinginga leaf-spring 11. A groove 12 formed in the periphery of the bolt normally receives the spring 11 and holds the bolt in its locking position. When the bolt is pulled outward, the rounded portion of the groove moving over the spring presses the same downward,`and thus allows the bolt to be moved until it is out of engagement with the sightpiece 3 and the head 1() abuts the spring. The spring is preferably held in the groove 13 in the bottom ofthe base-block by a screw 14.

It will be apparent-'that by slidingthe locking-bolt 7 outwardly the sight-piece may be easily removed and either reversed and again inserted in the groove or an entirely different sightpiece used. The sight-piece having been placed in the groove and one of the notches 5 being shoved into engagement with the bolt 6', it may be necessary to apply a IOO IIO

slight inward pressure on the bolt 7 to cause the same to pass into the notch 5 and securely lock the sight-piece in position.

The sight-pieces 3 may be provided with various styles of heads and, as shown in Fig. 8, may carry on one side of the stem 4 an ivory or color center of any nature 4, while on the other side may be arranged a polished or brilliant center 4b, which when used in connection with the reiiector 16 becomes luminous, or what is known as a combined Rocky Mountain and squirrel sight, as indicated at 4c in Figs. 1, 2, 7, 13, and 17, may be employed.

It is to be understood that it is wholly within the scope of our invention to employ various forms and styles of sights, as will be readily `seen by observing Figs. 13, 14, and 15. In Fig. 14 a pin-head'sight-center 4e is shown, which may be black on one end and provided with an ivory or suitable color-piece on the other end. Thus by merely reversing the sight-piece two kinds of centers are obtained by the use of a single sight-piece, and thus meeting the eXigencies of various lights.

In the central upper portion 8 is formed a recess 15, into which'normally fits the reflector 16. rlhe back or upper surface 17 of the reflector is concaved to lit the general contour of the portion 8 and is provided with a dull finish to obviate sheen, which would tend to distract the aim. The reflector is suitably hinged at 18 to the portion 8 and is provided with an upwardlyprojecting lug 19, which serves as a means by which the reflector may be raised and also acts as a stop, engaging with the portion 8 to hold the reector at the desired angle. It is apparent that when the reiiector is swung to the position indicated in Fig. 8 and the sight-piece having the sightcenter 4b inserted in the groove 2 the rays of light will be projected from the reflector ontothe sight-center, which is preferably concaved,

so as to collect and gather said rays, thus produclng an illuminated or luminous sight-center which will greatly facilitate the aiming of the gun. When it is not desired to use the reflector, the same may be folded down, as indicated in Fig. 6, thus being entirely out of the way and not in the least interfering with the sight.

In the back of the groove 2, so as to stand in rear of the sight-piece, are arranged a plurality of swinging rings or globes. The outermost globe 20 is provided with a pair of separated ears 21, between which stand the ears 22- of the intermediate ring 23, which are separated sufficiently to receive the stem 24 of the inner ring 25. The ears 21 and 22 and the stem 24 are pierced by the pivot-screws 26, which may be placed under friction, so as lto hold the rings in their raised and lowered positions, which ears and stem lie in the recess 27,Which is separated from the groove 2 by the bridge-Wall 28.

`ily aline with the center of the ring.

It is apparent that while the rings are mounted upon the same pivot-screws they are independently movable and that they may be swung up and down in a body or may be separately moved. The rings 2O and 23 are provided with shoulders 29 and 30, which engage the bridge-wall 28 when the rings are swung upwardly, thus assuring a perpendicular alinement of the rings. The stem 24 of the ring 25 is also formed with a shoulder 31, which abuts the bridge-wall 28 when the ring is raised. It will be observed that the sight-centers are supported in line with the common center of the rings when the same are, raised, and thus no matter which ring isswung upwardly the sight-center will read- It is also apparent that the sight-center will appear when observed from the front to stand within the ring or rings and that the same effect is had as where a globe with the sightcenter arranged therein is employed. The inner ring 25 provides all the advantages of what is known as the aperture sight-piece, and when it is swung-upward together with the outer ring gives the same appearance as the aperture and globe now commonly used and by inserting in the groove a sight-piece having a very fine sightcenter the same will aline with the center of the ring 25, thus producing a sight so accurate that the slightest deviation in the aim is readily discernible and by the, use of which the finest bead may be drawn. It is apparent that the aperture sight or ring 25 may be employed, as shown in Fig. 3, where the sight-piece is entirely removed, and also that the intermediate ring 23 may be swung downward and only the inner ring 25 and the outer ring 2O employed. Various combinations of sight pieces and rings are eX- peditiously had.

I t is to be understood that it is within the province of our invention to employ one or any number of rings, as in some instances it may be preferable to omit all the rings except the outer ring, while in other cases it may be desirable to use only the inner ring and the outer ring, or in still other cases it may be preferable to employ several rings.


Having now fully described our invention,

what we claim, and desire to secure by Letters Patent, is-

1. Ina device of the type set forth, the combination with an interchangeable and removable sight-piece, of a plurality of hinged rings independent of each other and each independent of the sight-piece.

2. In a device of the type set forth, the combination with a base and a sight-piece arranged thereon, of a movable ring and a reflector mounted upon the base.

3. In a device ofthe type set forth, the combination with a base and an interchangeable sight-piece thereon, of a pivoted ring, and a hinged reiiector arranged on the base.

4. In a device of the type set forth, the combination with a base and an interchangeable y reversible sight-piece arranged thereon, of a plurality of independently movable rings adapted to be alined with the sight-piece, and a reflector arranged on the base to act in combination with the sight-piece.

5. In a device of the type set forth, the combination With a base-block formed to receive a sight-piece, of an interchangeable and re-` ent interchangeable and removable sightpiece having a sight-center adapted to aline with the common center of any one of the rings when the same are elevated.
