Patented Sept. 25, 1945 r a Y- E-.5" PATENT OFFICE Gwilym Prideaux, Cleveland Heights, Ohio, assignor to General Electric Company, a corporation of New York Application December 3, 1942, Serial No. 467,749

, Claims My invention relates to sights of the silhouette type for firearms, such as rifles, carbines, shotguns, revolvers and the like.

In aiming firearms equipped with sights of the silhouette type, the object aimed at must be visible and the sights must be silhouetted on the object. Under certain conditions of illumination, such as under starlight or moonlight, the object may be visiblebut it is impossible to see the conventional sight silhouetted against the object. Accurate aiming of the firearm equipped with conventional silhouette sights is thus impossible under such conditions. 7

They principal object of my invention is to providea sight of the silhouette type which makes possible the accurate aiming of firearms under conditions of illumination such that conventional sights of this type are useless. Another object of my invention is to provide a silhouette type sight which is of simple structure and readily adjustable to suit the various conditionsof illumination under which it may be used. Other objects is a sight having a luminous part which is visible,

when viewed from the breech end of a firearm and invisible when viewed thereof.

In the drawing accompanying and forming part of this specification a species of my invention is shown in which Fig. 1 is a perspective view of my,

luminous sight mounted on the muzzle end of a rifie provided with a conventional silhouette V sight; Fig. 2 i a side elevational view of the luminous sight and the muzzle end of a rifle with part of the sight broken away to show the light source; and Fig. 3 is an exploded view of the luminous sight illustrated in Figs. 1 and 2.

Referring to the drawing, the luminous sight comprises a spring clip III which engages with the rifle barrel I I to support a casing I2 for the flashlight I3. One end of the casing I2 opens into an opaque housing I4 which encloses light-transmitting material I5. The casing I2 and the housing I 4 constitutes an enclosure for the other part of the luminous sight. The material I5 is of the kind through which light passes as does water through a'p-ipe. Quartz and Lucitej are ma from the muzzle end,

terials of this kind, the latter being an organic plastic material and, since its cost is less than that of quartz, the preferred'material for the purposes of my invention. The housing I4 and theenclosed material I5 are perforated to accommodate the barrel I I and are in two parts which fit together about said barrel II, as best shown in Fig. 3. The part of the opaque housing I4 on top of thebarrel I I is perforated as shown at IE to form an aperture on the side thereof facing the breech end of the rifle barrel II so that part of the upper portion of the material I5 is visible through the aperture I6 from that direction. The'material I5 is also juxtaposed to the end of the cas ing I2 opening into the housing I4. The flashlight I3 has an incandescent lamp I'I disposedat one end thereof and is inserted lamp end foremost into the casing I2. The casing I2 fitstightly about said flashlight to hold the latter firmly enough to resist the force of gravity when the rifle barrel is tilted from the horizontal and to; resist the physical shock incident to the discharge of the rifle. The flashlight is movable longitudinally of the casing I2, however, so that the distance between the lamp I! and the material I5 may be selected to attain the desired brilliancy of the portion of the piece l5 vis'ible through the aperture I6 of the housin I4.

The casing I2 and the housing I4 are separably joined to each other in the following manner.

As shown in Fig. '3, the housing I4 comprises two parts I8 and I9 which are secured to each other by the hinge 20 and which thus act as a pair of jaws. In the closed position of the jaws the opening 2| extends through the housing I4 and an opening 22 is provided for accommodating one end of the casing I2. The end of easing I2 to be held in the housing I4 has secured to the interior thereof, a by soldering, an annular sleeve 23 which'extends beyond said casing I2. The width of the sleeve 23 increases abruptly, the portion of greater width extending through a circular arc of more than A member 24 is secured, as by soldering, to the outer surface of the wider portion of sleeve 23 and is spaced from the end of easing I2 to form a groove or slot 25. The diameter of the opening 22 is less than the outer diameter of the casing I2 and is approximately the same as the inner diameter of said casing I2.

In connecting the casing I2 and the housing I4 the parts I8 and I9 are separated and the casing I2is disposed with the member 24 in the housing.

I4 and the groove 25 aligned with the parts of the housing I4 defining the opening 22. Theparts,

I8 and I9 are then moved together to join the casing I2 and the housing I4.

While the parts I8 and I9 of the housing I4 are separated, the parts 26 and 21 of the material I5 are also separated and are disposed in said parts I8 and I9, respectively. For clearness of illustration, parts 26 and 21 are shown in contact in Fig. 3. Thesightmay be mounted on the barrel I I by first moving the spring clip I 0 into engagement with said barrel II with the member 24 of the casing I2 in the direction of the muzzle end of the barrel II. The housing I4 with the parts 26 and 21 of the material I5 disposed therein is then clamped about the casing I 2 and the barrel II. The parts I8 and I9 overlap and releasably lock together as shown at 28 (Figs. 1' and 3) to hold the housing I4 and the material I5 on the barrel II and to engage the casing I2 with said housing I4. 7

- In order to align the aperture I6 with the conventional sight 29 on therifle barrel II the material I5 and'the housing I4 are so shaped as to form a wedge-shaped opening '34 to accommodate the sloping portion 30 of the conventional sight shown in U. S. Patent 1,983,362, issued December 4, 1934, having a lens to direct the light from the incandescent filament of the lamp I! in a, beam of parallel rays having a longitudinal axis coincident \mth that of the flashlight I3, and the lens end of the lamp I! may be inserted in the recess 32 to obtain maximum brightness of the material I5. Preferably the apex and the axis of the conical recess32' lie in the longitudinalaxis of the flashlight I3 when the latter is in the casing I2. The light emitted, by the lamp II impinging upon the surface of the material I5 defining the recess 32 enters said material I5 which then appears as a luminous body, a portion. of which is visible through aperture I6 in the housing I4. The brightness of the material I5 may be selected to meet the conditions of surrounding illumination for effectively aiming the rifle without dazzling the eye of the operator by moving the flashlight I3 longitudinally of the casing I2 to vary the distance between the lamp l! with respect to the recess 32 as pointed out above.

When desired, the apparent brightness of the material I5 may be reduced by interposing a light screen or filter between the eyeof the operator and the portion of the material I5 visible through the aperture I6. The screen or filter is conveniently disposed over the aperture lfijforexample it may be secured to the inner surface of I8 so as.

to extend over the aperture It When the parts I8 and'l9 are in the closed position shown in Figs. land 2. The light screen or filter may be disposed between'the lamp I1 and the material I5; for example, it may be in the form of a disc mounted in the casing I2 between the lamp I1 and the recess 32 for the purpose of reducing the brightness of the material I5.. Screens or filters which transmit red light are satisfactory. The

light tight so that the only light visible is that which may be seen through the aperture I6.

The flashlight I3 may be used as a general utilit flashlight when removed from the casing I2. The handle 33 of the flashlight I3 is used to move the flashlight I3 longitudinally of the casing I2 and to impart a rotary motion to the flashlight when the latter is inside or outside the casing I2 to switch the lamp I1 on and off. The frictional fit between the flashlight I3 and the casing I2 makes it possible to turn the battery enclosing portion of the flashlight I3 while the lamp holding-part 34 thereof remains stationary to engage and disengage the electrical contacts of the flashlight I3 to switch the lamp IT on and off.
