Specification of Letters Eatcnt.

Application filed. March 6 Y in the trade as electric lanterns.

One of the objects of my invention is to produce an electric lantern which simulates in general appearance a iainiliar form of oil-burning lantern, and in this connection other objects of my invention are simplicity of construction, inexpensiveness of manufacture, durability, certainty of operation and of maintenance in operable condition, and other more particular objects and advantages which will hereinafter appear.

My invention. includes features of construction and combinations of parts as will appear from the following description.

I shall now describe the electric lantern illustrated in the accompanying drawings embodying my invention and shall thereafter point out my invention in claims.

Figure 1 is a centr'al vertical section of the lantern with the lamp and battery in elevation. Fig.2 is an inverted plan with parts in section. Fig. 3 is a vertical section on a plane indicated by the line 33 of Fig. 2 as viewed from above. Fig. 4 is an elevation of the parts of the circuit closer. Fig. 5 is a vertical section, of the casing with the bottom closure in elevation at the lower left part of Fig. 1.

p The electric lantern embodying my invention illustrated in the accompanying drawings has a sheet metal battery-containing casing 1 of flattened cylindrical shape form ing the base or" the lantern. A sheet metal battery holding socket or clip 2 is supported in the casing 1 and is insulated therefrom by a paper ring 3 and a wooden disk 4.. The battery holder 2 is shown as secured to the lower side of the insulating disk 1 by means or" screws 5 and the disk 1 is secured to the top of the casing 1 by screws 6. A battery 8 having the usual outer insulating covering fits closely in and is gripped and Patented Nov. 21, into.

held by the battery holder 2 and thebentover or inclined contact terminal 9 of the battery 8 forms an electrically conductive connection with the adjacent end of the so 1 metal battery holder 2 as appears in Figs. 1 and 2 of the drawings and the other battery terminal 10 is left free or without electrical connections during the open circuit condition of the lantern as appears in Fig. 2. The battery holder 2 is open at the bottom and the lower side of the casing 1 is closed by means of a removable bottom 11, the central portion of which presses upon and assists to hold the battery 8 in place in the battery holder 2. The bottom closure 11-is--- removably held in place in the casing l by means of slight outwardly indented lugs 12 which engage above an inturned rim at the lower edge of the casing 1 as clearly appears in the drawings, a notch 13 being provided v in such rim to provide for the attachment or removal for the bottom closure 11. By reason of the insulation of the electrically conductive battery holder 2 from the casing 1, both of the contact terminals 9 and 10 of the battery 8 are insulated from the casing 1 in the open circuit condition of the lantern this being the condition shown in the drawings. v

A screw-threaded metal lamp socket 14 has an inner flange as shown resting'upon and forming an electricalconnection with the outside of the top of the casing 1. The lamp socket 14 is held in place on the casing 1 by combined retaining screw and contact member 15, the head of the contact screw 15 being within the lamp socket 14 and this screw passing downward through the top of the casing 1 and through the wooden insulating disk 1 and engaging a nut 16 countersunk in the lower side of the wooden disk 1. The apertures for the passage of the contact. screw 15 through the bottom of the lamp socket 1i and the top of the casing 1 are sullicient-ly large that the screw does not come incontact therewith and the head of this screw within the lamp socket is insulated therefrom by means of a small insulating disk or washer 17 and the lower end of the contact screw 15 comes into contact with and forms an electrical connection with the upper side of the battery holder 2, as appears in Fig. 1. An ordinary miniature incandescent lamp 18 is shown as screwed into the lamp socket 14 so that its central contact. terminal is in 7 contact with the head of the contact screw 15 and hence in electrically conductive connection with the spring battery terminal 9 of the battery 8 and the other contact termicloser is provided upon the cylindrical or peripheral portion of the casing 1. A circuit closing metal strip has one end portion forming a spring contact finger 19 within the casing 1 and has an oppositely projecting combined guiding and locking end por tion 20 at the inside of the casing 1 and has a median outwardly turned U-shaped loop 21 which projects to the outside of the casing 1 through a slotted opening or guide aperture 22 in the casing. A short retaining pin 23 passes through the projecting loop 21 and projects therefrom at each end for holding the circuit closing strip in place on the casing. The retaining pin 28 is held in place in the loop 21 by means of an indentation at the outside of the loop, Fig. 4:, forming a corresponding inner projection which enters an annular groove in the retaining pin 23, Figs. 3 and 4. The contact finger 19 is bent inward away from the easing 1 at its free end in position to engage the contact terminal 10 of the battery 8 when the slidable circuit closer is moved in a counter-clockwise direction as seen in the inverted view afforded in Fig. 2. The other end portion 20 of the slidable contactv strip is provided as shown, with successive indentations adapted to be successively engaged by an inturned projection 24 on the casing 1, Fig. 2, for securely maintaining either the open circuit or the closed circuit condition as desired. I

A convex reflector 25 surrounds the lamp socket 14 being shown as rising substantially to the same height as the top of the lamp socket. The top of the casing 1 is provided with an upwardly projecting screw-threaded globe-supporting flange 26 which is shown as having an annular fiat inner portion secured as by soldering to the top of the easing 1. The reflector 25 is shown as provided with a Hat marginal or peripheral flange fitting within the globe-supporting casing flange 26 and the reflector 25 is firmly held in place by a lantern globe 27 screwed into the casing liange 26 down upon the peripheral flange of the reflector 25. The lantern may be readily carried about by means pf a bail 28 which engages a cap 29 show-rv as screw-threaded over 'the top of the chimney,or globe 27.

It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described within the principle and scope of my invention.

I claim:
