ELECTRIC LANTERN.

Application filed August 10, 1921.

To all whom it mag concewt: I 1 Be it known that I, HANSIA. RINo,'a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented a new anduseful Improvement in Electric Lanterns, of which thefollowing is a specification.

This invention relates particularly'to electric lanterns operated by dry cells; and the 10 primary object is to provide an improved lantern which is adapted to the use of dry cells of the type commonly employed in flash-lights.

The invention is illustrated, in its pre- 16 ferred embodiment, in the accompanying drawings, in which-- s Fig. 1 represents an elevational view of the improved lantern; Fig. 2, a bottom plan view of the same; Fig. 3, an enlarged verti- 20 cal sectional view taken as indicated at line 3 of Fig. 1 Fig. 4, an inner View of thereflector employed; Fig. 5, a broken'sectional view showing. a modification by which the device is converted into a hand-lamp or flash- 28 light; Fig. 6, a broken detailed sectional view illustrating the manner in which the bail or handle is connected. with the tubular standard or casing of 'the lantern; and Fig. 7, a vertical sectional view of a modification 30 of the construction shown in Fig. 3.

Referring to Figs. 1 to t, inclusive, and

Fig. 6, the construction shown comprises a tubular standard or casing A which is of insulating material, such as hard fiber; a base or spider B upon which the standard A is mounted; a bail or handle C connected with the upper portion of the member A; and dry cells D of the flash-light type confined in the casing A.

The tubular standard or casing A hasses cured to its lower end an annular bell-shaped member or ring A which is provided at its lower end with an external thread 1 which screws into an internally threaded ring B which constitutes a part of the base or spider B. The upper end of the casing A has secured thereon a-yrin 'A which is externally threaded andfwhich has applied thereto a re- .movable cap A The capA is made of sheet-metal, and confined therein in'contact therewith is a metal disk 2 which is provided with a downwardly struck spring tongue 2 which affords acontact. An insu- Serial No. 491,157.

lation disk 3 is located adjacent the inner surface of the disk 2, and has a slot 3 thru which the s Jring contact 2 extends.

The bail comprises a wire member which is" curved in circular form and provided at its extremities with eyelets or perforations 4. The ring A has secured thereto lugs 5. (see Fig.6), which are provided with threaded bores which receive screws 6v which serve to connect the bail C to the lugs 5. The base or spider B comprises, in addition to the substantial metal ring B, a heavy wire base ring 7 from which rise arms 8 which serve to support the ring B in an elevated position. Two of the wire arms 8 have threaded extremities which extendthru the ring B, the ring being secured thereon by means of nuts 8. The ring B is equipped above the points of the connections with the other wire arms 8 with externally threaded bosses 9, upon which are secured removable caps 10. The ring B is recessed at its upper side thru the bosses 9, as indicated at 11, thus providing bores which are internally threaded. The caps 10, together with the recesses 11, afford chambers for extra lampbulbs 12, whose shanks are screwed into the threaded bores 11. g

The ring B is threaded as shown to receive the threaded portion 1 of the bellshaped member or ring B of the standard A. Below the internally threaded Wall of the ring B is an annular flange or lip 13 which serves to support a concavo-convex metallic reflector 14, whose convex side is turned'downwardly. The reflector is provided centrally with a threaded socket 14 which serves to receive the lamp 12 The reflector is equipped internally with a spider or bracket 15 upon which is mounted an insulation plug 16 thru which extends a central contact stud 17 whose lower end 17 makes contact with the central contact of the lamp-bulb. The upper end of the stud 17 is equipped with a contact 17 upon which the bottom of the zinc can of the lower cell D rests.

V The cells D are provided with the usual carbon poles 18;, the carbon pole of the upper cell engaging the spring contact 2 The tubular standard or casing A is equipped interiorly on one side with a lower metal strip or conductor 19 and with an upper metal strip or conductor 20. The casing is also equipped at one side with a switch 21 provided with a slide-button 21 which is adapted to make contact with a contact mem ber 19 with which the strip 19 is provided at its upper end. The lower end of the strip 19 is extended downwardly so as'to project below the ring A and is so formed as to provide a spring contact l9 which engages the inner surface of the metallic reflector.

The lower end of the conductor or strip 20 is connected by a rivet 20 with the frame of the switch 21; and the upper end of the strip 20 is connected by a rivet 20 with the upper end of the metal ring A It will be seen that when the switchbutton 21 is in contact with the contact member 19*, the circuit will be closed. The circuit passes thru the cells to the contact member 2 at the upper end of the tubular standard, thence thru the cap A to the ring A thence thru the rivet 20 thence thru the strip 20 to the switch, thruthe switch to the strip 19, thence to the metallic reflector, thence thru the lamp, and from the central contact of the lamp thru the contact 17 to the bottom of the lowermost cell.

It will be noted that in the construction described, the tubular standard of the lantern forms the housing for dry cells which are series connected by simple cont ct with each other; also, that the lantern standard is provided with a circuit, or partial circuit, external to the cells, the external partial circuit being equipped with a switch. It will be noted, further, that the lamp bulb is housed or protectedby the spider which supports the lamp standard, and that the lower or convex surface of the reflector serves as a reflecting surface which throws the rays from the lamp in every direction. Also, the tubular standard is ren'rovable from the base or spider B, and is itself pro vided with a removable top or cap which is equipped with a contact, which prefer ably is a spring contact.

The threaded portion of the metal ring or bell A is shown as having fitted therein a removable insulation ring 23. This may comprise a strip of heavy cardboard bent into annular form. It will be noted that when the ring A is screwed into the ring B, the end of the ring A clamps the peripheral portion of the reflector against the annular flange 13. As shown in Fig. 3, the reflector is insulated from the ring P) by means of athin gasket 24:.

In the modification shown in Fig. 5, the

tubular member A carries the bell-shaped member or ring A inthe manner already described. The lower cell B, however, does not extend so low as in the above described construction; and a reflector ll 'is mounted in the bell A in the manner now familiar in flash-light construction. The spring contact- 19 is correspondingly shortened to contact with the convex surface of the reflector. A lens 25 is secured in position by means of a retaining ring 26. In the manufacture of flash-lights and electric lanterns, certain parts may be made interchangeable, as this illustration serves to show. Thus, where a manufacturer is engaged in the manufacture of flash-lights and electric lanterns bot-h, economy in manufacture may be effected by reason of the interchangeability of some of the parts. The construction thus far described is adapted for use in connection with standard flash-light or battery hand-lamp dry cells. T

In the modification shown in Fig. 7, pro vision is made for the use of a dry cell of larger diameter than that employed in the standard construction. Also, the modification shown in Fig. 7 illustrates the reversi bility of the dry cells and also the use of a metal tubular standard or casing. 111 this construction the tubular standard or casing is designated E. It has secured to its lower end an externally threaded ring E which is only of slightly greater diameter than the casing itself. It has secured to its upper end a metal ring E with which the bail C is connected. A cap E is applied to the threaded ring E The cells D, D are inverted. The cap E is in electrical connection with the zinc can. of the upper cell llthru the medium of a conical coil spring 2r.

The base or spider is designated F. It has a: ring F into which the ring R of the standard E is screwed. The reflector G is clamped between the lip 28 of thering l1" and the lower end of the ring E, the reflector being insulated from the ring F by a gasket 2-9. The switch 30 is equipped with a sliding button 30 with which is connected a conducting strip 30" whose lower end affords a contact 30. lVhen the contact 30 engages the reflector G, the external circuit or partial circuit is completed. The strip 30* may be retracted, however, to break the circuit.

The improved construction provides a lantern of pleasing design, which can be manufactured at moderate cost. This construction enables dry cells of the flash-light type to be employed, the cells being properly connected in series by simply introducing them into the lantern. The lantern may be handled practically in the same manner as a flash-light, if desired, the tubular standard being of small diameter and serving as a handle, as for example, where it is desired to use the device as an exploring light. Moreover, if desired, the bail may be removed, in which case, the device becomes in effect a battery lamp for exploring purposes, but provided with a cage or protecting guard, this function being served by the spider-like base; Again, the device may be laid on its side, wherecircumstances make this desirable, without detriment to the device.

The foregoing detailed description has been given for 'clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should becon'strued as broadly as permissible in view o-fthe prior art.
