ELECTRIG LANTERN.

Application filed. March 8, 1924. Serial No. 697,922.

" This invention relates to lanterns, and

more particularly to electric. lanterns.

The principal objects of'the invention are the provision of an electric lantern that is a strong and sturdy, is not likely to become broken or get out of order, that is easily assembled, cheap to manufacture, eflicient and reliable in operation, that is constructed to protect the battery against the elements an. and that simulates in appearance the con,-

ventional lantern having a. skeleton :Erame. Other and further objects-and advantages ofthe invention will appear from the following description taken in connection with the accompanying drawings, in which Fig. l is an elevation of a signal lantern embodying the present invention;

Fig; 2 is a vertical section on line 2-2 of Fig. 1;

Fig. 3 is a of F ig. 1;

Fig. 4 is a vertical section on line H of Fig. 3, with parts broken away;

Fig. 5 is a plan view of the contact member; 7

Figs. 6 and 'Z are detail views showing a modified form of the device;

Fig. 8 is a sectional view oi a modified form of the device with parts broken away;

character 10 designates the lantern support,

a frame or cage, 11 the battery container, and

12 the battery.

Thelantern support,- cage or frame 11- may be of any suitable construction. Preterably it is a skeleton structure comprising a base, a body portion supported thereby, and a handle for said body portion. The support is substantially the same in appearance and similar in construction to the convenin the form of a ring horizontal section on line 8?;'

Fig. 9 i a view similar to Fig. 8, showing tional type of signal lantern employed by railway employes at the present time. The base comprises a ring 13 to which are secured a plurality of wire supporting members 14; which are arranged symmetrically about said ring and extend upwardly therefrom. Their intermediate portions are bent inwardly as at 15 and are rigidly secured in any suitable manner as by soldering or spot welding'to a support 116 which may be which is adapted to support the battery container. 11, as will presently appear. The upper sections-of the 'supportingmembers 1 1 are bowed outward- .ly to form the body portion and have their upper ends secured to an upper ring or hoop member 17 as shown at 18 in Figs. 1 and 2.

An intermediate ring or guard 180 is secured to the bowed portions of thesupporting members 14 for holding the same in proper spaced relation. The ring 130 is also held in s aced relation to the container -11 whereby t e switch 19 is protected by said ring or hoop-from accidental manipulation. r

The lantern is provided with a .bail 20 which is detachably but rigidly secured to the frame 10 by means of brackets 21 and 22 which are secured to the upper ring 17 and to the members 14 at opposite sides of the frame. The brackets 21 and 22 are provided with keyhole slots 23 and 24 in which are adapted to engage the headed studs 25 and 26 secured to the ends of the bail 20.;

Theresiliency of the bail 20 holds said studs in the outer or restricted ends of the slots 23 and 24:. The bail is removed by conipressing the same and removin the studs through the enlarged portion 0% the slots.

The battery container 11 is mounted within the cage or frame 10 and is supported by the ring 16. A reflector 27 may be and preferably is interposed between the container and said ring. This reflector may be of any suitable construction, that shownbeing composed of a series of concentric bands, the.

cross section of each of which is a section of a parabola, w1th a common focus. The

container is preferably provided with a central opening in which is secured a depending sleeve or socket 28- whichis adapted to.

extend downward through an. opening in the lens 27. electric light bulb 29 is suitable manner as by means of clips 35 integral with said band which extend through slots in said disk and are adapted to be bent over against the lower side thereof to retain the same. within said. slots, as shown in Fig. 4. The clips are held in spaced relation to the bottom of the container by the head 30. The member 33 is of less diameter than the disk 32 whereby the same is insulated from the sides and bottom of the container.

A central contact or conductor member 36 extends axially through said disk 32 and is adapted to be engaged'by the central terminal 37 of the lamp bulb29. The bulb is grounded on the sleeve or socket 28 as is usual in such constructions.

The battery 12 is carried by the conftainer with one of its spring "terminals 38 in contact with the annular band 33 and its 4 other spring terminal 40 in contact with the central contact member 36 as more clearly shown in Fig. 4.

While the battery 12 is shown as being rectangular in cross section, it is understood that it may be otherwise. As showman angular type of battery .is employed. and a.

guide 42 is secured across the container, which insures the positioning of the battery therein in such a manner that the corners of the battery willnot interfere with the manipulation of the switch 19. The use of a central and an annular contact membei' insures proper electrical connection in any manner in which the battery may be inserted in the contain'e Suitable means are provided for-properly maintaining the battery in electrical connection with contact members 33 and 36. As shown, the container 11 is provided with a-lid 43 which is adapted to telescope the upper end ofsaid container. A spring 44 secured in and carried by said lid is adapted to engage'thebattery and resiliently hold the same in lowered position.

The lid 43 is held inloweredposition by any appropriate means, such as the bail shaped securing member 45 which is pivotally secured to the frame 10 as by having its ends connected to the loops 46 and 47 formed in two oppositely arranged supporting members 14 as clearly indicated in Fig. 2a The securing member 45 is pro- Vided between its ends with an inwardly extending bend 4% which is adapted to ensees gage' a depressibn 48 in the dome of the lid 43 for holding the parts in assembled relation with the lid in contact with a bead 49 on'the receptacle. The resilience of the bail-like securing member 45 will prevent the projection formed-by the bend 470 from becoming accidentally disengaged from the The container 11 being supported on the ring 16 and the lid 43 being applied lid 43.

to it, the securing member 45 is forced into engagement with the depression 48, thereby urging the lid down upon the container,

binding the latter to its seat, and also through the spring 44, insuring good elec-v trical connection with the battery.

The container is provided-with a suitable switch 19 comprising a resilient metallic strip 50 secured to a reinforcing strip 51 of insulating material .by means ofa fas tening member 52. The strip 51 prevents the battery irom coming in contact with the strip 50. The member 52 extends through a slot incthe container and'is seciired to an operating member 53. A shield 54 which is more or less resilient is clamped against the container by the member 52 to form a weather-tight joint for protecting said "slot in any position of said switch.

The strip 50 hasits lower end 540 bent inwardly to extend beneath the strip 51 whereby when the same is lowered as shown in Fig. 4 it will engage the band 33 and ground the battery, i. e. close the circuit through the electric light. The upper and lower ends of ;the strip 50 may be provided with beads 55and 56 which are adapted to snap into the depressions 57 and 58 respectively tohold the switch eitheropen or closed.

The ring or hoop member 17 is provided with an offset loop or bend 59 for accomodating the operating member 53 of the switch 19 in removing the container from the frame.

r The likelihood of breaking or burning out the filament or breakingthe bulb renders it. desirable to-make provision fbr carrying extra bulbs for replacements. Means for accomplishing this is shown in Fig. 2 and comprises one or more sockets, in-the' present instance a single one, secured to thecap '43. Preferably the socket 64 is attached to the dome of the lid as at 65, and when the extra bulb 66 is secured therein it will be protected by the dome of the lid and the spring 44 which will extend about the same.

The form of the device shown in Figs. 6 and 7 differs from that just described in that the lid. 60 has a flat top which is engaged by a different type of securing bail 61.- The bail 61 is pivoted to swing in a,

vertical plane and its freeend is provided with a latch member 62 pivoted thereto andv provided with a notch 63 forengaging the upper ring or hoop member lZ-for holding the lid on to the battery receptacleor' coirion the horizontal flange 68 of which aflords a ledge on which the flange 69 of the bowl 70 is adapted to rest. The bowl 70 is'of transparent material of the desired color.

In order that the relation of the fastening means and the cap 43 shall not be affected by variation in the thickness of the flange of the bowl, the reflector 270 is provided with a flange having a depending portion 71 of such width as to support the reflector and the container above the flange of the bowl. The use of the depending portion 71 of the flange not only insures the correct position of the container for enabling the fastening means or bail 45 toproperly engage the cap, but also relieves the flange of the .bowl from all strain due to the compression of the cap by said fastening means 45. If desired, gaskets 72 and 73 of any suitable material such as rubber may be interposed between the reflector 270 and flange'69 and between the flange 69 and the ledge or flange 68, respectively, whereby the space between the reflector and lightdome is air tight thus preventing the entrance of dust and dirt, and also preventing the tarnishing of the lens to a greater or less extent.

In the construction shown in Fig. 9, the

special form of support for the bowl 70 is dispensed with, the bowl being seated on the supporting ring 16 of Figs. l'and 2. In

Fig. 10 there is shown a clip 74, secured to' the inner surface of the cap 43 for holding an extra or replacement bulb 7 5.

1n railway service the failure of the lantern, due to the destruction of the bulb filament, might result in disaster to a train, and it is important that the lantern be equipped with a replacement bulb for use in such contingency. p

It is thought from the foregoing taken in connection with the accompanying drawings that the construction and operation of my device will be apparent to, those skilled in the art. Various changes in size, shape, proportion and details of construction may be made without departing from the spirit and scope of the appended claims.
