ELECTRIC LANTERN.

Application filed May 28, 1915. Serial No. 80,885.

To all whom it may concern:

Be it known that I, J OHANN G. PETERSON, a citizen of the United States, residing at Jersey City, in the county .of Hudson and State of New Jersey, have invented certain new and useful Improvements in Electric Lanterns, of which the following is a specification.

This invention relates to electric lanterns, among the principal objects of the invention being the provision of an article of this nature which is simple in construction, susceptible of inexpensive manufacture, the parts of which can be readily assembled and which has means of an effective character to prevent. accidental movement of a circuit controlling or switching member from off to The invention comprises other features of novelty and advantage, which with the foregoing will be stated at length in the followmg description wherein .Iwill set forth in detail that one of the several forms of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present s ecification. 1 do not restrict myself to this disclosure; I may depart therefrom in several particulars within the scope of the invention defined by the claims following1 said description.

eferring to said drawings: 7 Figure 1 is a top plan view'of a lantern involving my invention, the cover being re moved. Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1, looking in the direction of the arrow and showing the cover in position.

inclusive being on a larger scale than Figs. v

The lantern comprises a suitable source of electrical energy such as the battery 2 which as shown consists of the well-known dry cell. This battery is preferably suitably incased and protected, and the box or can 3 answers satisfactorily in this connection. As represented the box or can is equipped with a removable cap or cover 4. The body of the box or can is preferably of conducting mate .rial such for instance as tin, so that it resents part of the lamp circuit. While it is not imperative that the cover or cap 4. should.

be of metal, it is conveniently made ofthis substance, and as will be inferred, tin .isv

suitable for 'the purpose. The box or can 3 may be provided with a suitable handle such asthe bail 5, only a part of which,'however, Said bail is connected with the body of the box or can 3.

The lamp is denoted by 6 and it has the customary contact shell 7 and the central end contact 8. As shown the \contaot shell is screwed into the contact shell'ortube 9 provided at its inner end with a circumferential circular flange 10 fitted against and in electrical contact with the inturned annular flange 11 of the approximately frusto-conical lamp and reflector case 12 of metal, brass answering the necessary requirements. This flange 11 fits against and is in electrical contact with the box or can 3, and the means for holding the case 12 in position will be hereinafter described. Associated with the lamp 6 is the reflector 13 and lens 14, both carried by the case 12. 1

Inside the box or can 3 is a contact as 15 shown as resilient and which can be'formed 'up conveniently from sheet metal. Said con- .tact member 15 is disposed between the battery or cell 2 and the inner wall of the box or can 3, the free portion thereof extending upwardly above the top of the battery to cooperate with a secondcontact as will hereinafter more particularly appear. .Between the contact member 15 and the box or can 3 is interposed a strip of insulating material such as 16; fiber presents a suitable substance in this regard. Also disposed between the.

cell 2 and the box or can 3 is an attaching member such asthe plate 17. Between this plate 17 and the butt portion of the contact member is a piece of insulation as 18, and

fiber may be provided for this purpose. Asv I shown the butt portion of the contact member 15 has lugs'19 bent over the upper and lower edges of the insulation 18. The plate 17 as represented is provided with peripheral projections 20- extending through registering openings in the insulation 18, butt portion of the contact member insulation 16, can 3, and flanges 11 and 10, the forward ends of these projections being bent over the front face of the flange 10 whereb% the parts mentioned can be securely and e ectively held in assembled relation, The lamp 6 is so mounted that its contact end can project through openings in the can 3 and insulation 16, by reason of which its central end contact 8 can engage the butt portion of the contact member 15 at which time, as will be clear, the contact shell 7 of the lamp is in contact with the supporting contact shell 9. Supported by the battery or cell 2 is a I suitable insulating member such as the disk 21 of fiber and eyeleted or otherwise suitably connected'to this insulating member 21 are the

contact members

22 and 23, the body of the contact member 22 being longitudinally slotted to receive the screw 24: of one pole of the battery 2, whilethe body of the contact member 23 is slotted to receive the body of the screw.25 of the other pole or terminal of the battery. The upstanding portion 22 of the contact member 22 presents. the contact proper thereof, being cooperative with the contact member 15, being as will be evident somewhat resilient. The upstanding portion of th'e'contact 23 has electrical connection, bycon'tact,with the inner surface of the can or box 3. It will, therefore, be clear that if the lamp 6 is in position and that if the contact 15 and upstanding portion 22 of the contact 22 be bridged, the lamp will be lighted. The circuit controlling or switching member is preferably carried by the removable cover 4 and a circuit controllin member such as meets my requirements Wlll now be described. Said circuit controllin or switching member involves in its 'ma e up the central spindle 26 extending through a hole or provide with a button or manipulating portion 28. The spindle is further provided with a circular enlargement or collar 29 fitted in said perforation or opening 27 for turning movement. The lower portion of the button or finger piece 28 overlies'the cover 4. The connector of the circuit icontrolling 0, an it ma for instance be of brass,'hav'- mg at' ts en s the lobes31 and 32. It will so be noted-that the lobe 31 is of greater width than the lobe 32, which presents one conven ent means for preventing accidental closing of the said circuit controlling or switching member as will-hereinafter more 66 particularly appear. Fitted around the erforation 27 in the top 4,-being or switching member is denoted by.

spindle 26 are the insulating pieces 33 and 34 which may be also of fiber, the lower insulating piece having the central boss 35 extending comparatively snugly into the cen-- tral opening of the connector 30. The insulating)pieces'33 and 3 1 and the connector 30 may manner, for instance by staking the inner or lowerend of the spindle over the lower insulating part 33 as shown at 36. The spindle 26 is disposed between the resilient contacts of the

contact members

15 and 22 and by turning said spindle, the connector 30 may be turned therewith to either move the connector to the open or the closed position. Said connector is shown in dotted lines in Fig. 1 in the open position and in closed position in full lines in said view. In the latter position it simultaneously engages the contacts of the

contact members

15 and 22 so as to effect the lighting of the lamp 6 if the latter be in place. The article is shipped with the circuit controlling or switching member in open position. It is subjected naturally to jars or vibration. No matter in which direction it may be moved accidentally under the conditions noted or something similar, the circuit controlling member or the connector 30 thereof cannot be closed. When the connector 30 moves in one direction from the open position thereof as shown by the full lines in Fig. 6, the wide lobe 31 will strike the contact ofthe contact member 22 before the narrow lobe 32strikes the contact of the contact member 15, whereas if the connector moves in the opposite direction or to the dotted position 1n Fig. 6, the wide lobe 31 will strike the contact of the e clamped together in any desirable contact member 15 before said narrow lobe can come against the contact of the contact member 32, so that in each event the circuit cannot be closed. By turning the spindle 26 through the agency of a button 28 or its equivalent, the connector 30 can be easily -moved to circuit closing position as shown connector simultaneously accidentally en both contacts.
