This invention is a signallantern and has for its objectthe provision of a simple light and inexpensive lantern'in which the light will be furnished by an electric current and will be visible from any point at which the lantern may be viewed. The invention 'provides a lantern which may. be utilized as a spot light and alsoprovides a lantern in which the light rays will be disseminated freely in all directions from the lantern.

The invention is illustrated in thea'ccompa nying drawing and will be hereinafter fully set forth.

In the drawing: i g Figure lis a sectionalelevation of a lantern embodying the invention, and

Fig. 2 is a vhorizontal section on the line 22 of Fig. 1;

In carrying out the invention, there is provided a base 1 which is an opaque shell of metal tapering upwardly from its lower edge and having its lower edge'entirely in one plane whereby it may rest upon a table or other support. At the top of the base 1, there is formed a chamber 2by providing an annular rim coaxial with the baseandhav- 1 ing a horizontal partition 3 extendinga'cross the base at the top of the same, this partition also constituting the bottom of the chamber. At the center of the partition 3, there is formed a threaded socket 4 adapted" to receive an electric lamp bulb 5, and to the under side of the partition is secured a parabolic reflector 6 concentric with said opening so 1 that, when the lamp is energized, thelantern may be utilized as a spot light, the base 1 serving to cut off the lateral rays fromthe lamp and the reflector directing the rays onto 7 r the spot which is to be illuminated. Upon the top edge of the bowl or chamber 2, there is hinged .a metallic lid 7 which has its outer surface brightly polished so thatit constitutes a parabolic reflecto'r'and at the center of this combined lid and reflector is a socket 8 adapted to receive an electric lamp bulb 9. Vithin the chamber is a support 10 consisting ofa block built up oflayers of insulation, and through and upon this block are secured electric terminalsill and 12 which are in the form of resilient fingers adapted to bear 1529. sria No 360,165. 7

The ib attery 'isofthe dry cell type and carried a containerlfi which disposed between the upper ends of the posts; 13 and issupported therefrom by braces-'16, said' braces.

An insulated wire 22 leads-from the contact 21'under the bottom-ofthe lining and then up through the space' between theliuihg and (80 thewallof the container toa pairofswitches 3a id @Wh ay be o anyapp o yp Er oin' the opposite ends of theswitches, the wires 14 lead through the post 13 to the term mi nalsj11;and:12, as hasbeen stated; The

posts ,l3 are reinforced at points intermediate their length or ,he'ight'by a reinforcing ring 25 and. a similar ring is preferably provided at the upper endsofthe posts. Se- 3 cured to the sidesof the posts arejarms 27 extending upwardly and fitted to a handle .or'ha'il 28 of wood or fiber orother insulating material whereby the lantern: may be easily M and comfortably carriedand manipulated. lit 5 ;Within the chamber Q arefa plurality of spring clips 29 in which sparebulbs may be engagedand'held'so that should a bulb'burn out a new bulb may besubstituted therefor aton'cem It is to be noted that the switches 23 and 24; chamber engaging the respective lamps, and conductors leading from the battery through are arranged upon the outside of the battery container and at such a point that they may be conveniently manipulated by the thumb of the user without releasing his hold upon the handle 28, and a cover 30 of any approved form may be provided over the container to prevent the battery cell from accidentally dropping therefrom. The braces 16 and the posts 13 constitute a metallic connection between the outer shellor wall of the battery container and the rim of the chamber 2 so that, when the cover 7 is closed, there will be a grounded return from the lamps 5 and 9 to the negative contacts 20 and through said contacts to the battery. The positive side of the battery is connected with the center contacts of the lamp through the wires and switches, as previously described, so that either lamp'may be energized at will. The reflectors 7 and 19 are opposed to each other and the lamp 9 is disposed between them so that the lightrays issuing from the lamp will be reflected in'all directions laterally from.

the lantern and, consequently, the signals may be observed from any viewpoint. The posts and the reinforcing ring 25 form a verylight skeleton frame for the lantern so that the obscuring of the light by parts of the frame is minimized and the disadvantage of the ordinary lanterns in this respect is overcome. Vhen the spot light is to be used, the a lamp 9 may be de-energized so that the only light issuing from the lantern will be that sent out by the lamp 5 and this light, of

course, will be directed onto the spot which is to be examined. The positive conductors are very effectually housed by the wall of the battery container and the lining therefor and pass to the lamps through the hollow post 13 so that they are protected against accidental breakage and do not detract from the appearance of the device.

Having thus described the invention, I claim:

1 A lantern comprising a frame, a chamber carried by the frame, a reflector hinged to said chamber to constitute a lid therefor, a lamp mounted centrally upon said reflector, a second reflector carried by the frame in opposed spaced relation to the first reflector, the lamp being exposed between the two reflectors, and means for energizing the lamp.

2. A lantern comprising a base consisting of an imperforate upwardly tapered wall, a chamber carried by the top of said base, a reflector carried by the bottom of said chamber within the base, a lamp mounted at the center of the reflector, a cover for the chamber c011- stituting a reflector, a lamp mounted externally of the chamber at the center of said cover, a frame including a hollow post fixed to and rising from said chamber, a battery carried by the frame, terminals within said the hollow post to said terminals.

In testimony whereof I afiix my signature.

JAMES BARON HARLEY.
