Y. Application med November 25, was.:.senza No.l 409.603. j

This invention relates to lanterns such as c tho-se used by railroad trainmen, switchs men, etc., in Vsignaling at night. To lessen the fire hazard and general inconvenience of oil burning lanterns `there lhas been a v considerable desire to use' an electric lamp. Several' 'designs'of'such lamps have been tried out but forvarious reasons `without satisfactory results. v

Cnel such design has included the `customary handle and skeleton framewith thel lamp extending downwardly in the lower portion of the frame and with a battery carried between lthe handle and lamp. OneV serious Objection to this lamp hasfbeen'its high vcent-er of gravity, making it top heavy and easyto topple over." Another objection has been the poor visibility yof, theflightfat times".v l'lhefv necessity of swinging the lamp in either or both a vertical and horizontal'. plane makes it necessary for thelamp't'ofbe seen on all sides and lprecludes"solution of the problem of deficient light intensity by the usel vof the usual parabolic reflectors. Such reflectors would not vallow thetransmission of. someof the signals, when, forexample, the brakeman swings his'lantern over his head. Y .c Y One object of this invention is to over#A come these disadvantages and provide a conY` 1 venient, compact and' inexpensivel lantern capable of 'being seen much better at a distance thanis the usual eleotric'lanterny re' gardless of the direction in which the lantern swings. f Another object is to get a maximum light intensityfor a minimum cost.

Another object -to mountA an v,electric Ylamp. or bulb so as to distribute y.light-rays similarlyto the familiar oilburningla'nt'ern being mounted vso that the bulbextends up?` wardly from the base.Y f ,Y According to thisinvention an axialrelector is mounted on one -side of the lamp sov that anotherlight image is provided adj acent. the lamp, boththe lamp and this image being visiblefrom all around'directions, this image being adj acentthelainp and causing the two apparent li ghtsourcesto appear as a single .5G-and larger light source whenfviewed from .af

j 'rigeis detail-sawing' distance. Specically two conical reflectors are arranged'with their apices closely adj acent the lampone below and o'nevabovethey lamp. To make the lamp and image appear larger a small .removable globe is used, s 55,

designedthat theilamp appears larger, it magnifying the raysv on all sides and atthe top.` Tov provide for diifejrentcolored lights this'globe may be'made of the desired color and a vnumber of- `different colored globes e carried, since the globe is a vest pocket size vand readily attached or removed yduring use;l

of the lantern. j, instead of having a pushbutf,v ton or other projectingswitch yactuator in the way of the user whereit is likely to bey accif dentally opened or closed, the switch cone. Y 7

Vtrolling the lampis located between'theilamp andl battery 'and operable in response to "rela,-Y

tive movement between the lamp base vand the battery. The simplicity and few number of 70 the parts necessary make thisswitchmuch superior to those whichl have'previously been used in such lanterns.,

VReferring to the drawings Fig.`1. shows one embodiment of thisinven-f tion.V `H

the globe between thetwo'r'eectors. F ig. 3 is a Vsectionthrough the" upper re'-v flector and top of the lantern..

v f ,K Fig. t is a perspective showing the bayonet Slots the sides ofthe lamp base.

Fig. 5 is atop view showing thelamp base in place on the-battery but with-the upper, portion of the reflector broken awa 85 spring c ip for the Fig; 6Y isa-detail of the globe. Y

Fig. 7 isa lside view of a lantern embodying the preferred form ofthe invention.

Figs. 8 andQ' are detail views showing the 9aV receptacle'for. spare globes and lamps.'

` f In Fig. 1 th'eglanternillustrated comprises f the usual handle 10, preferably of insulating material or covered with insulation and secured. to the .supporting frame 11,*which is o5 ofthe .general-[shape shown. An electricA lamp bulb 12 is supplied from a battery 13 of c the v'customary dry cell type through one terminal 14` of thebatteryconnected tothe .center contact ofthe lamp',V while fthe other j 100 Awhen the lamp is not in use. 20'

lterminal 15 is grounded to the lamp base or Yis secured to the container 16 by means of pins 22 on the container entering the bayonet slots 18 shown more clearly in Fig. 4.

The yieldable latch or spring member 19 secured to the side of the cover as shown prevents the pins 22 from accidentally coming out of their slots when the lantern is Ain use. rlhe top 20 of the cover 17 is provided with a central opening through which one terminal 14 of the battery projects to engage the center lamp contact. The top of the cover also has an opening 21 through which the Vother battery terminal 15 may project A strip of insulation 21 prevents the battery terminal 15 from accidentally contacting with the cover.

To supply current to the lamp the cover 17 is rotated relative to the container 16 and bat- ;tery 13 until the terminal 15 engages the top 25 e 22 and bayonet slots 18 are made of different sizes so that it will be impossible for the cover to be fitted to the container 16 in any but the correct manner.

Y As shown in Figs. 1 and 2 a conical reflector 23 is located below the lamp and another conical reflector 24 whose sides slope more 'steeply is arranged above the lamp with its apeX adjacent the lamp so that in use an image of the lamp is seen 'on'the' upper reflector 24` near its apex. These reflectors are preferably chromium plated so as not to tarnish in use since they are not protected. To malre p the light source on the lamp12 and its image on the reflector' 24 appear larger a magnifying globe 25 fits over the lamp and is readily removed. Y y

This. globe, is so shaped as' to enlarge the appearance of the filament whenviewed from any position on all sides or vfrom the top, so that the image in the reflector 24 also is enla-rffed. 50 2D The lantern top 26 is pivotallyy secured at 27 as shown in Fig. 3, and a spring clip 28 engaging the under side of the frame member 29 retains the top 26 in position during use but permits the top tobe readily raised. Pivot 27 has its aXis substantially parallel to the plane of the handle. 10.l This permits the top to be raised so as to permit access to the reflectors, the lamp and the battery and removal, replacement or repair of the parts.

The upper reflector 24 may be'pivotally secured to the top 26 and afterthe top has been raised this reflector may be movedfrom its .position by swinging it around its pivot 30 upon release of the spring clip 31 holding the reflector in position with respect to the top 26. n Y

The spare globe 32 and lamp bulb 33 are shown as being held above the reflector 24 by means of the spring Vclips 34 and the support 35 respectively. When the reector 24 has been dropped one of these spare globes or bulbs may be removed or inserted. When the top 26 is raised and the reflector lilrewiselraised away from thelamp,the globe 25 is removable by an upward thrust which disengages the globe from the spring lingers 36 engaging the inside ofthe globe, as shown in Fig. 6. These spring fingers 36 are secured to a metal gaslret 37 fitting around the base of the lamp and preventingv the entry of any rain or snow jinto the lamp soclret when the globe is volf or being changed. l ,y

Vilithin the reflector 24 or top 26 may be carried globes 'of different colors so that a light of any desired color can be available on removal of the existing globe and Vsubstitution of the globe of the desiredcolor.

ln operation rotation of the cover 23 with respect to the container 16V causes the contact member 15 to engage or disengage the top 20. rl`he lamp base and cover 17 fits over the container sufficiently snugly so that therer is no danger of the switch being opened or closed accidentally. In all operative positions of the switch the pins 22 are within the slots 18 and prevented from accidentally be-` coming disengaged by'the finger 19 of spring member 19. To remove the/battery the cover 26 and reflector 24 are first raised to an outof-the-way position.

Then the lamp base and reflector 23 are the slots 18. Then the' lamp baseand reflector ik can be slid upwardly oil the container 16. The battery may be readily withdrawn and a new one inserted when the cover 17 is removed. f i i l The upper-reflector 24 is preferably removable-*for instance-#it may have a flange 40 and pin 41 interlocking 4with a lia-nge 42 proi jecting downwardly from the top. lThis flange 42 forms a chamber in which clips 43 and 44 may be provided so as to permit the carrying of extraer spare globes and/or lamps of any desiredcolor. It is thus possible to readily change the color of the light asis frequently necessary lin R. signalling'. `Al'single lantern may thus take' the*` place of a number' of different colored lanterns. Y
