- Specification of Letters Patent.

Application filed'August 23, 1905.

Patented May 17, 1910.

Serial No. 275,401.

To all whom "it may concern:

Be it known that I, WAnn H. SNYDER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Firearms, of

. which the following is a specification.

, dial.

improvements in relation to the firearm which permits the light to be projected on a line parallel,with the projectile or at an angle thereto, as desired. I

In the drawing: Figure 1 is a sideelevation of a revolver showing my invention applied thereto. Fig. 2 is aside view of the light with the spot omitted. Fig. 3 is a side elevation of a gun showing the gun barrel and the direction of the light parallel to each other. Fig. 4 is a side elevation showing my invention applied to a n barrel and so adjusted that the projecti e and the dark s ot will converge at any predetermined istance desired and indicated by the When my invention is'u'sed in connection with a revolver I refer to apply and arrange'it substantial y as illustrated in Fig. 1, which shows-an electric light bulb 1, suitably connected to a battery 2 in the handle 3 of the revolver 4 which I provide with a trigger 5 to display the light and a tri 'ger 6 to discharge the rojectile after the light has been "displaye I preferably -'prov1de in or near the lens 7 an opaque spot 8 which,

when the light is thrown, will cause a dark spot to be projected into the light area in the path of the projectile, and enable the user to shoot an object with accuracy at night by simply aiming at the projected target shadow or spot without sighting.

It will be seen that in Figs. 1 and 3 the light is projected on a line parallel with the projectile while in Fig. 4 I have shown of the light.

\ WVhile I have shown my invention applied to a revolver and gun barrel it is obvious that it may be-used in connection with any firearm. I

My invention is specially applicable tor use in connection with large guns used principally by'the Government where the target is at long range and it is necessary to dlscharge the projectile at an angle to the line of light as shown in Fig. a in order to carry the projectile to the target fired at.

The .dial 9 is used to determine the point at which the target spot (used to mark the object fired at) and projectile will be comcident with each other. The pointer 10 will always be on a line with the center of the cone of light radiation, and the barrel 11 will be adjusted at an angle thereto to carriy; the project-ileto the desired distance whrc will be shown by the target spot, 12, the dial 9 preferably moving with the gun barrel.

I have arranged the trigger 5 for operating the light on a different plane and independent of the trigger 6 for operating the gun, so that the li ht maybe displayed as long, as desired be ore discharging the gun and Without any danger of discharging the gun byunintentional excessive pressure on the trlgger 5 for displaying the light, said triggers 'being arranged in a convenient mannerto' be operated by diflerent fingers, and being preferably arranged upon difi'erent planes. This makes the use of the light displaying device absolutely safe when used to discover the identity of an individual.

It will be apparent that my invention is capable of considerable vmodification with-. 2

out departure from the scope or spirit thereof, and for this reason I do not wish to be understood as limiting myself to the details 1 of construction, but v What I desire to secure by Letters Patentis: Y 1. 'A search light for firearms having a lens provided with an, opaque spotlat its vertex, said lens being transparentcontinu ously about said spot, whereby a shadow. will be cast at the center of the circle of the light rays passing through the transparent part of the lens.

2. In combination with means fordirecting a projectile, a source of light, a lens associated with said light, an opaque spot on associated with said source 0 said lens in the line of itsprincipal axis,

said lens being transparent continuously about said spot, whereby a shadow will be cast at the center of theycircle of the light rays passing through the. transparent part centratin'g light rays emanating therefrom,

means for projecting azshadow within said concentrated light rays and surrounded thereby, the trajectory of said projectile and said shadow coinciding at one or .more points.

4;. In a device of the class described,means for directing a projectile, a souroeof light, means associated with said source for concentrating light rays emanating therefrom, means for projecting-a shadow within said concentrated light rays and surrounded thereby, said means being relatively adjustable Whereb said shadow and the trajectory of said pro ectile may be made to coincide at any desired point.

- 5. In combination with means for directing a projectile, a source of light operatively associated with said directing means, means light for con erases from into a light pencil, means for project- ,ing a'shadow centrally of said pencil of rays and surrounded entirely by said pencil of rays and means for adjusting said light directing and concentrating means relative to said projectile directing means to secure coincidence of trajectory'at a predetermined point. I

6. In a device of the class described, adjustable means for directing'a projectile, a source of light, means associated with said source of light for concentrating the light rays emanating therefrom into a pencil of light rays, means for rojecting a'shadow centrally of said pencil of light rays and entirely surrounded by said light rays and an adjustable connection between said projectile directing means and said light dipredetermined angular relation to each other recting means including an indicator whereby sald two means may be dlsposed in a to secure coincidence of trajectory of the two at any predetermined range.
