APPLICATION mEnxuLY 22.1916.

Patented Mar. 26, 1918.



Specification of Letters Patent.

Patented Mar. 26, 1918.

Application led July 22, 1916. Serial No. 110,783.

To all whom t may concern:

Be it known that I, RICHARD T. JACKSON, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Sight for Firearms, of which the following is a specification.

This invention has reference to sights for rearms, and its object is to produce a front sight which may be employed as a magnifying sight with the point of sight close to the gun barrel, and which when the rear sight is elevated for distant shooting, may, without any change whatever, be utilized for point blank shooting.

In accordance with the present invention there is provided a hinged sight member with means for carrying a lens and a spider providing cross lines, although by producing the cross lines on the lens itself the spider may be omitted. The hinged lens carrying member is provided with the usual bead sight and with another sight appearing above the lens sight, which is utilizable as a point blank sight when the rear sight of the gun is elevated for distant shooting.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not conned to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications come within the scope of the appended claims.

In the drawings Figure 1 is a central vertical front to rear section of a front sight of the magnifying t e.

y1Fig. 2 is an elevation partly in section of the front sight turned down for the utilization of the usual front bead sight.

Fig. 3 is a rear elevation with parts in section of the sight as shown in Fig. 1.

Fig. 4 is an elevation of the sight shown in Fig. 2 as seen from the right hand slde thereof.

Fi 5 is a view similar to Fig.. 1 but showing the lens and cross line splder in elevation, and illustrating dust caps applied to the sight.

Fig. 6 is a rear View of one of the dust caps on a smaller scale than Fig. 5.

Figs. 7, 8, 9 and 10 are views of different forms of cross line spiders.

Fig. 11 is a face View of a magnifying lens or the front sight with cross lines produced directly thereon.

Referring to the drawings, there is shown a basic member 1 designed to fit the usual dovetail groove in the front end of a rifle barrel. This basic member 1 has spaced ears 2 thereon traversed by a pivot screw 3 extending from one ear to the other and also traversing a hinge member 4 on which is formed, or to which is attached a ring 5. This ring is internally screw-threaded from one face and adapted to the screw threads is a locking sleeve 6 having a marginal flange 7 at one end which may be milled, as shown at 8, for convenience of manipulation. The inner periphery of the ring 6 `is formed with a rabbet 9 to receive a lens 10, so that the locking sleeve 6 supports and clamps the lens 10 against a flange 11, or against another device which may be introduced therein and which will be presently described,

Extending from the hinge member l in a direction perpendicular to the ring 5 is a bead sight 12 visible when the ring 5 is laid down against the rifle barrel, and constituting the usual front bead sight used in gun sights of the gene-ral type of the present invention.

It is customary to employ round bead sights, but when such sights are viewed through the customary V-groove of a rear sight, they are liable to hide too much of the iield. To avoid this the sight 12 is made of square or diamond shape, and hence the object covered by the sight when the gun is in use is hidden to a less extent than is the case with the usual round or bead si ht.

In order to center the front sight, it as been the custom with lens sights to provide cross lines 1.3 directly upon the glass of the lens, as indicated in Fig. 11. With the present invention the sight is provided with one or more rings 14 having cross lines 15, as in Fig. 7, or one horizontal line 16 and a single upright central line 17 extending from the bottom of the ring to the cross line, as in Fig. S, or equi-distant lines 18 spaced one hundred and twenty degrees apart as in Fig. 9. Still another form of sight is shown in Fig. 10 where a small diamond 19 is carried by supports 20, so as to occupy the center of the field, and while it may be of ample size for the purpose, occupies but a very small fraction of the field, and hence permits ready view of the object aimed at.

On that portion of the ring 5 diametrically opposite to the hinge a is a sight member 21 which may also be of diamond shape, although other shapes may be used. However, for reasons already given the diamond shape is to be preferred. The sight 21 constitutes a point blank sight because when the rear sight is set for distant shooting and is therefore considerably elevated, a near-by object is sighted with sufficient accuracy through the already set rear sight and the high point blank sight 21. Of course, for distant shooting the magnifying sight is employed in connection with the rear sight, but for close shooting magnification is not needed, and often there is no time to readjust sights for near or point blank shooting.

|The ring 14 is provided with a projection E22 at one point about its periphery adapted to enter a notch 28 in the inner wall of the ring 5, so that the ring 14 is always properly positioned, and is held in place by the locking sleeve 6 whether or not the lens 10 be present. The spider ring 14 is not limited to any special design or material, but is preferably black on one side and white on the other, since it is easily removed, reversed and replaced at will.

The sight 12 is useful with either a rear peep sight or with open sights.

l/Vhile the arrangement shown in the drawings is to be preferred, the particular shape of the lens carrier, whether round or of other conformation, is not material.

The lens 10 is liable to become soiled or injured when not in use, and in order to protect it, removable caps 24, 25, respectively, are provided, these caps constituting dust caps and are suitably formed to be sprung into place. While each cap is shown with a split flange 26 by means of which it will retain its position in the sight ring 5,

Copies of this patent may be obtained for this feature is not at all obligatory and any means for holding the caps in place may be employed. j j l.

1. A front gun sight provided with magnifying sighting means, and other sighting means associated with and higher than the first sighting means, said sighting means having respectively different and non-coalescing sighting axes, whereby the magnifying sighting means may be used for distant shooting and the higher sighting means for near or point-blank shooting without adjustment of the said sights but requiring an appropriate change in pointing of the gun.

2. A front gun sight comprising a hinged ring having the axes of the hinge transverse of the length Of the gun barrel for movement of the ring from a position substantially flat on the gun barrel to an upright position, said ring having a magnifying lens and sighting means associated therewith for distant shooting, a sight 0n and projecting from the ring at a point diametrically opposite to the hinge, and another sight on and projecting from the ring adjacent to the hinge and in a direction parallel to the direction of projection of the first-named sight on the ring, said axes of the magnifying means and the first-named sight projecting from the ring having` respectively different and non-coalescent sighting axes, and the magnifying sighting means, and the second-named means projecting from the ring having the same sighting axes with respect to the gun when the front gun sight is turned into one position or the other about the hinge.

3. A front gun sight comprising a ring with a locking sleeve threaded therein and having an interior rabbet, a lens adapted to the rabbet, and a spider ring adapted to the first-named ring to be clamped therein by the locking sleeve, said spider ring constituting a sight member for use in connection with the magnifying means.

1n testimony, that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.
