LANTERN.

Application filed January 9, 1920.

To all whom it may concern Be it known that I, ETHEL INGALLS linun. a citizen of the United States. residing at Kansas City, in the county of Jackson and State of Missouri. have invented certain new and useful Improvements in Lanterns; and l do declare the following to be a full, clear. and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same. reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon. which form a part of this specification.

This invention relates to lanterns and particularl to a lantern containing :1 light source from Which the beams or stream lines of light may be emitted through the wall of the lantern in a determined design or configuration.

The invention contemplates the provision of means whereby a figure may be projected upon a screen and whereby beams of light may be projected about the figure in the form of a halo or aurora, the desired result being prefernblv accomplished through the medium of reflectors used in conjunction with the light source. The particular construction of the preferred embodiment of my invention ill be apparent by reference to the following description in connection with the accompanying drawings, in Which Fig. I is a perspective view of a lantern constructed in accordance with my invention.

Fig. II is a vertical. longitudinal. sectional view through the lantern casing.

Fig. III is a sectional view through one of the slots in the casing through which the beam of light may project. and

Fig. IV is a diagram of the projevtwl beams of light surrounding the central figure at one end of the lantern.

The invention is illustrated as consisting of a cylindrical case 1. one end of which is closed by a panel 2 having a transparent or translucent panel I! of any desired mmtiguration, the present one being shown as in the form of a five pointed star.

The other end of the casing 1 is closed by a convex reflector 4. axially of which is a lamp socket 5. into which may be screwed an incandescent lamp 6. constituting the light source. The lamp socket may be con- Serial No. 350,404.

nected to a suitable source of electrical current through the conductor 7 and the plug 8, as will be well understood.

About the perimeter of the casing, that is. in the wall thereof is a plurality of longitudinally extending slots, some of which are of greater length than others. The shorter slots are designated 9 while the longer slots are designated it) and in the embodiment of the invention selected for illustration, the longer slots 10 are spaced equi-distantly about the perimeter of the lantern at about 72 of the circle to provide five relatively long beams of light opposite the points 11 of the star-shaped figure 3. it being understood. however. that the disposition of the slots may be varied without departing from the spirit of the invention.

The slots 9 and 10 are bounded by upwardly curved. reflecting surfaces 12. which reflect the rays of light from the light source in diverging beams, the slots 9 emitting less light and as these are all of substantially uniform area. they will emit light beams substantially like those designated 13 in Fig. TV. while the beams 14 will be emitted through the slots 10.

\Vhile the surfaces 12 binding the slots 9 and 10 enhances the appearance of the beams on account of their reflecting qualities. I do not Wish to be limited to reflecting surfaces at this point as satisfactory results may be obtained by simply cutting slots in the casing 1, although the reflecting surfaces do add to the general appearance of the design.

The lantern is preferably used in corn nection with a translucent screen 15 and in actual practice I prefer to place the panel 2 in close proximity with the screen. as indicated in Fig. TI. The filament of the light source is then energized to illuminate the interior of the lantern. 'lhc rays of light reflected from the reflector 4 through the panel 3 will provide a relatively sharply defined figure on the translucent screen 15. while the halo. as indicated in Fig. iV. will appear lhrough the screen as a result of the projected beams of light through the slots. the slots being preferably in the front of the lantern in close proximity to the panel 2. as indicated.

ll is obvious that other designs may be formed by varying the outline of the panel 3 and the disposition of the slots or lightemitting openings 9 or 10. or both. which are about the perimeter of the lantern and I, therefore, Wish it understood that I do not limit myself to the particular arrangement shown but reserve the right to make such changes and alterations as Ji'opei'iy come within the scope of the appended claim.

The lantern is pariitnlarly applicable foe use as a store Window (ii-iteration but ohviously the manner of use or location (10nstitutes no part oi the present invention.

\Vliat I claim and desire to set-Lire by Let,- ters-Patent is:

A lantern comprising a, casing having longitudinal slats in the pertain OK the slbta-beihgilargfiit rtlcrlihinhf the other slots whereby light beams of varying lengths are grojected about a common center, the larger" s'lotsWi'Ihg eqnitlistantly spaeed about the light souroe, a reflector in the casing to project lightthrough the slots, 20

and allifz hesoumezinfiwmt of the reflector. In testimony whereof I affix iny SIQHAUHQ.
