1 Claim. 1

This invention relates to picture or image projecting pistols, and aims to provide a picture projector possessing novel and useful features, whereby pictures may be projected on to any suitable surface such as, for instance, a wall, by pulling the triggerof the pistol.

A further object of the invention is the provision of a picture feed means whereby a plurality of separate and independent picture films, each containing a single picture, may be inserted in the feed means selectively, the latter being operable :by the trigger to advance a single picture into the projector frame of the pistol simultaneously with the flashing of a light bulb. Successive pulling of the trigger replaces the picture in the projector frame by the next succeeding picture.

The above and other objects will become apparent in the following description, wherein characters of reference refer to like-numbered parts in the accompanying drawing. It is to be noted that the drawing is intended to serve the purpose of illustration only, and that it is neither desired nor intended to limit the invention necessarily to any or all of the specific details of construction shown excepting insofar as they may be deemed essential to the invention.

Referring briefly to the drawing,

Fig. 1 is a cross-sectional view of the pistol taken on the line ll of Fig. 2.

Fig. 2 is a cross-sectional view of the same taken on the line 22 of Fig.1.

Fig. 3 is a fragmentary enlarged perspective view, partly in section, of the film holding means, showing films in position thereon.

Fig. 4 is a perspective View of one of the two opposed projector frame forming members, showing the means for attaching it to the pistol housing wall.

Fig. 5 is a perspective view of the trigger per se.

Fig. 6 is a view taken on the line 66 of Fig. 3,

.with the films omitted.

Referring in detail to the drawing, the numeral It indicates the pistol housing, that is, a housing formed in the shape of a pistol, having the side walls H and I2, the cover 13 hinged at It, and

the handle [5 wherein the battery cells l6 are mounted.

A drum ll is rotatably mounted on a shaft l8 supported in the side walls ll-lZ, and is shown having a ratchet 19 on each end although but one such ratchet is necessary in the device as illustrated. A trigger 26 having a handle 2| is D otally supported at 22 on a pin 23 mounted in the side wall II. A coiled spring 24 secured to the trigger at 25 and to the wall H at 26, normally urges the trigger into cocked position. The transverse section 28 of the trigger is provided so that the pawl extremity 29 of the trigger may engage the ratchet l9 against the wall ll.

. A pair of parallel-spaced endless belts 38 of y suitable flexible material such as, for instance, rubber, are provided and adapted to be trained about the drum ll in such fashion as to form the equivalent of the two edges of a flexible belt. Continuous opposed longitudinal grooves 31 are provided in the belts or strips 38, interspersed at regular-intervals by obstructions or spacers 32 formed integral with the belts 33. Individual rectangular picture or photograph films 33, each bearing a separate complete picture or photograph, not shown, are inserted into the equivalent belt formed by the two strips 38, by inserting their opposite edges into the grooves 3! between successive spacers 32.

Projector end tracks or guides 34 are mounted, by means of supporting brackets 35 secured thereagainst, on the walls ll-IZ in vertical position and in complementary fashion so that together they consistute a vertical frame. These guides contain complementary grooves 36 in which the belts 30 register slidably. If desired, any suitable stifiening members, not shown, might be mounted, either fixedly or loosely, between opposed spacers 32 between successive films 33 to augment the films 33 in maintaining the spacing between the belts 30.

The number of teeth on the ratchets l9, and the dimensions of the various parts on the belt system, are of course to be such that pulling the trigger once advances the equivalent belt the distance between the transverse center lines of two successive spacers 32; thus, each pulling of the trigger will cause the next successive film 33 to be positioned upright in the guides 34. A lens 36 is positioned forward of the guides 34 in any suitable or customary manner.

I Battery cells it are mounted in the handle l5 and rest upon a spring contact 31. A lamp or light bulb 38 is mounted in a socket 39 which is positioned substantially as shown, and an electrical circuit is formed with the cells l6 through the lead strip 40, the spring contact finger 41 whose extremity engages a terminal 42 of one of the cells It. A spring contact finger 43, secured to and projecting from the trigger 20, is so positioned as to ride frictionally across and in contact with the other cell terminal 44, so that the circuit ispclosed through the bulb 38 when the trigger is moved to the right (Fig. 1). Thus, each time the trigger is pulled a new picture is presented before the bulb to be projected on a wall or other suitable screen,

This invention permits the use of picture films photographed by the person himself, whence he may project his own pictures instead of having to purchase standardized shots. Any size of suitable film may be provided, a common size being the 35 mm. film. The separate films may be inserted selectively between the belts 30 after lifting the cover l3, and since the flexibility of the belts permits of their easy separation, their edges may be readily registered in the grooves 3| as stated above. If stiffening members, or ties, are used between the belts and are fixed in their relationship to the belts, as mentioned above but not shown, the films could easily be inserted into the grooves 3| by bending the films to register their edges in the grooves, in an obvious manner.

Obviously, modifications in form and structure may be made without departing from the spirit and scope of the invention.

I claim:

A picture projecting pistol comprising a housing including a barrel, said housing having a handle, battery cells in said handle, a trigger pivoted to said housing, a drum rotatable in said housing rearward of the barrel, opposed complementary vertical guides mounted in the side walls of the barrel near the muzzle thereof an endless flexible belt trained about said drum and registering in said guides, said belt having film receiving means between the edges thereof, said edges of said belt comprising strips, said strips having 1ongitudinal grooves cut into the juxtaposed inner walls of said edges, said grooves having transversely aligned obstructions therein thereby providing spacers in said grooves defining the length of the individual films. said grooves between successive of said'spacers providing said film receiving means for the insertion of the edges of the film thereinto, means partly on said drum and partly on said trigger for advancing said belt a distance equalsubstantially. tQ-the length of one of said films upon pulling of said trigger, means normally retaining the trigger in cocked position, a light bulb mounted between said drum and said guides, a lens mounted forward of said guides,

v circuit means connecting one terminal of said bulb with one terminal of said cells, and means on said trigger for closing said circuit through said bulb upon said pulling of said trigger.
