Be it known that we, EDWARD F. .NAssoir and YGno'ne'n E. JoHNsoN, citizens of the; United States, 'resi'dingat Sparks, in the county of NVashoe and State of Nevada, have invented new anduseful Improvements in Lantern Attachments, of which the fol-f lowing isa specification. 1.

This invention relates to lanterns, particularly to'those used by railroad men for: signaling and other purposes and has forits object the provision of an attachment for a. lantern of this character adapted to replace the oil font and burner whereby to convert the lantern into an electrical lantern, the attachment being in the nature of a lantern containing a plurality of dry cells and have ing a socket carrying an incandescent bulb.

An important object is the provision of an attachment of this'character which isncorr be slipped into the bottom portion of a rail road lantern after the oil burner and font thereof have been removed, thenattachment being held iniplace by a holder engaging against the top thereof and; against the top of thelanter 1 w Another object is the provision of a device of :this character which has built thereinto a simple switch mechanism 'whereby the current maybe ttuned on or off, as desired. An additional object is the provision. of a device ofthis character which will. be simple and inexpensive in manufacture, easy to in stall, highly efficient in use, durable in service, and a general improvement in the art.

lVith the above and other objects and ad vantages in View, the invention consists in. the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which Figure l is a side elevation of the lantern, Figure 2 is a vertical longitudinal sectional view, I

Figure 3 is "an elevation of'our device detached and showing the parts assembled,

Figure 4 is a similar view showingthe parts separated,

Figure 5 is a plan view of'the lower part of the attachment, V

Figure 6 is a perspective view of the battery.

Figure 7 is a perspective view of the means for holding the shell and battery within the base. j

Figure 9 is a" detail cross'sectionalView showing theiswitch device in elevation, and

, Figure-10 is a horizfontal sectional-view taken through the switchdevice showni n Figure 9;.

.Referring more' 'particularly to the draw ings, the letter A designates the-wire frameof :the lantern which is shown as being off I the well known type used 'trainmen and others,-'and Bdesignat'es theitop, hinged as. shown atC, and provided with a catch D for holdingit closed. Depending fromtliis' .top is the usual flangeE. fThe letter F designates the handle which is connected with the'frame A in the usual manner whereby to be either pivoted or to be locked rigidly The letter-G designates the base or bottom of the "lamp which is secured within the lower fportion'oftheframe A and which 7 ordinarilycontains the oil font andsupports' the burner. 'lh'e oil font and burner'are not shown carrying out the'presenti vention they must-be removed. I

' ;Ingcarrying o utour invention provide, -,a1:shell.-10 which'is' formed as an inve rted cup memberand which is'provided with "an outwardly:extending flange 111 adapted to" seat upon the top of the base G5 Formed inv the-center of the top of thisshell is asoc-k'et 12 within which is screwed the shank of an inc'andescentbulb 1'3. Disposedwithin this shell is a battery'lt form'ediof anysu-itable' number of dry cells connected, or'it may be preferred touse a single large cell. This battery is'enclosed withina protective casing 15 -which' may be ofcard-board or the like and-within-theupper-end of which is-diswhich is of course electrically .connected with the cells to form one terminal. Located posedan upwardly spring-pressed plate 16 within one side of the casing 15 is a metallic strip 17 which forms the other terminal. This battery seats within the'base firmly engaged within the shell 10.

In order to prevent dislocation of-this attachment weprovidea disk 18 flanged, as shown at 19, "and adapted to engage the flange E of the top B; Depending from this G and is' disk at diametrically opposite points are rods 20 which carry at their lower ends ar-v cuate plates 21 which engage against the outi side of the shell l0-and which engagethe'top of the flange 11 for holding the shell and battery firmly in position within the base G. The socket 12 carried by the shell extends through a central hole 22 in the top of the casing 15 and engages the spring-pressed plate 16.

The switch structure associated with the device comprises a block 23 of insulating material secured upon the inside of the shell 10. v iecured upon this block is a leaf-spring 24 which when the parts are assembled on gages the metallic strip 17. Secured transversely of this block 23 is a strip 25 and journaled through this strip and through the block and shell is a rod 26 having an angular end 27 serving as a handle. The spring 24 terminates in spaced relation to the strip Secured upon the rod 26 is a contact arm 28 which is of course grounded on the shell and this contact arm is movable to engage the spring 24 so as to complete the circuit through the bulb.

In the use of the device it will be seen that the battery is disposed within the base G with the shell 10 fitting upon the top thereot. These parts are held in position by an auxiliary frame including the disk 18, rods 20 and plates 21. lVhen the rod 26 is turned to bring the arm 28 into engagement with the spring 24:, the current will flow through and energize the incandescent bulb 13, as will be obvious. lVhen the use of the device is not desired, it is merely necessary to turn the handle 2'? through an arc of ninety degrees, whereupon the current will be cut off and the lamp deenergized.

From the foregoing description and a study of the drawings it will be apparent that we have thus provided a simply constructed and consequently inexpensive device for transforming an oil lantern into an electrical lantern, the device being easily installed and being so simple as not to get out of order, as well as having the great advantage of not being subject to being blown out by wind or rain.

\Vhile we have shown and described the preferred embodiment of our invention it is of course to be understood that we reserve the right to make such changes in the form, construction, and arrangement of parts as engaging against the underside of the top of the lantern, rods depending from said disk,

and plates carried by the lower ends oi said rods and engaging said shell whereby to hold said shell down.

2. In a lantern including a supporting frame and a base, an attachment replacing the oil font and burner ordinarily disposed within the base, the attachment comprising a battery of dry cells enclosed within a casing and fitting within the base, the top of the casing having a hole, a spring-pressed plate within the casing electrically connected with the battery to form one terminal thereof, a shell fitting upon said battery and seating upon said base, a socket carried by said shell, projecting through said hole and engaging said plate, a bulb within said socket, and a switch mechanism carried by the shell and connected with the battery and the bulb whereby to complete the circuit' there through, said switch mechanism comprising a metallic plate on the casing connected with the battery and formingthe other terminal thereof, a block of insulating material secured within said shell a leaf-spring carried by said block and engaging said'metal-lic strip, a cross strip on said block, arod journaled'through the shell, the block and the cross strip and having its outer end. formed with a handle, and a-n'arm on said rod mov able to engage said spring, the rod, arm, and socket being grounded. on the shell.

In testimony whereof we aliix our signatures.

EDWARD F. NAHSOIY. GEORGE JOHNSON.
