RAILROAD ELECTRIG LANTERN.

Specification of Letters Patent. Patented Aug. 10, 1920.

Application filed August 16, 1919. Serial No. 318,012.

electric lantern, which will display either a red, green or white light, and is especially adapted for use as a railroad signalv lamp.

Another object of the invention is the provision of a lantern in which the source of light is normally housed within the lantern casing to afford protection when not in use, but which is capable of being moved to extend. beyond the casing and of being auto matically lighted when in this last named position.

Another object is the provision of novel means for lighting the lamps or bulbs of a lantern, so that either a red, green or white light may be quickly brought into position for use.

A. further object the provision of a lantern capable of resting upon either its top or bottom and when in the latter position having its light shielded or protected, and when in the former position exposing the light, so that it may be seen from acousiderable distance.

Other objects and advantages of the invention will appear as the follmving dei-wriptii'iu is read in connection with the acconipauying drawings.

in the drawings:

l igure .1. is a perspective view of a lantern embodying the present invention.

lhig. Q is a bottom plan view of the same.

.l ig. 3 a view similar to Fig. 2,, with the bottom cap removed.

Fig. a1- is a vertical central, section through the lantern, showing one of the bulbs in lighted position by dotted lines.

Fig. 5 a section at right angles to Fig. el.

Fig. (i an clevation showing the lantern in reverse position from that shown in the other figures of the drawing and showing one of the bulbs exposed.

Fig. 7 is a fragmentary section showing the manner of housing the battery Within the lantern.

Referring more specifically to the drawings, like characters of reference denote corresponding parts throughout the several views.

As shown in the accompanying drawings,

the lantern includes a casing 10 of suitable size and shape, the one herein shown being rectangular. This casing is divided transversely by a partments 12 and 13. The last named compartment is lined with suitable insulation 15 and contains a battery 15. This battery may contain any desired number of cells and may be one of the commercial batteries now in use. terminals 16 and 17, the former contacting? with the partition 11, through an opening in the lining 14 and the latter contacting with a plate 18, extending through said lining and insulated from the partition 11.

Located within the compartment 12, is a rotatably mounted shaft 19, the saidshaft being mounted in a bearing bracket 20 and.

having one end in contact with a frame arm 21, secured to the casing .10, to provide electrical continuity from the contact 16 through the casing to the shaft 19. The 0})- positc end of the shaft extends through the casing and has mounted thereon a turn button 22, by meansof which the shaft may be rotated. Mounted upon the shaft 19, is an insulating block 23, which is preferably of rectangular cross sectional shape, and is provided upon three of its sides with metallic contact strips 24. ()no end of the block 23 is surrouiuled upon three sides with a metallic member 25 having arms 26 extend ing over and insulated from the contact strips 2-21, by a strip of insulation 27. Each of the arms 26 carry a lamp socket 28, for the reception of a bulb 29, the latter being covered by a globe 30 mounted upon a holder 31. These globes are colored to provide signal lights and include a red, a green and a white globe. It is preferred to ar range the globes with the green interposed between the red and white, as the latter are the ones more frequently used, but it is, of

course, apparent that this may be governed as desired it being merely necessary to change the globes to arrange the lights in any order.

Located in a pocket 32, formed upon the interior of the casing 10, is an insulating block 33, the said block carrying a spring contact arm 34 for engagement with any one of the contact plates 24 as the shaft 19 is partition 11, to provide com- It is provided with opposite.

rotated. The arm 34: is electrically connected to the plate 18, through the medium of a wire 55, which is secured upon a stud 36, which serves to secure the plate 18 in position.

Secured to the casing 10, is a support, which comprises a base formed preferably of a ring 37, which is connected to the casing by means of arms 38, which extend through the casing, as shown in Fig. 3 of the drawings. This provides means for supporting the casing, so that any one of the bulbs may be extended through a slot 39, formed in a cap i0. which is removably secured to one end of the casing 10. The

opposite end of the casing is covered by a cap 41, which serves to hold the battery in position and may also act as a support for the lantern when in the position shown in Fig. 6.

The lantern is provided with a handle 42, which is pivotally secured to each side of the casing 19 and which may be held against pivotal movement by engagement with a notch 43 located upon each side of the casing.

From the foregoing description and the accompanying drawings it will be seen that the invention provides a lantern in which the source of light is normally housed within the casing, the said lantern containing a plurality of diiferently colored bulbs, any num-' ber of which may be moved to a position to extend beyond the casing and to be automatieally lighted when in such position.

The invention further provides a lantern which may be used in a reversed position to. vform a stationary lamp, with its light projected above the casing, so as to be seen from a. considerable distance.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention. what is claimed is:

l. A lantern comprising a casing having an opening in one end thereof. a shaft mounted for rotation within the casing and disposed transversely of the opening. electric bulbs carried by and extending radially from the shaft and included in a normally open circuit, means whereby the v haft may be rotated to project any one of the lllllllrthrough said opening and means for automatically closing the circuit when one of the bulbs is thus projected.

2. A lantern comprising a casing having an opening in one end thereof. a shah mounted for rotation within the casing and disposed transversely of the opening. electric bulbs carried by and extending radially from the shaft and included in a normally opened circuit. means whereby the sha fl may be rotated to project any one, of the bulbs through saidopening and combined means for closing the circuit when one of the bulbs is thus projected and for yieldingly holding the shaft against rotation.

3. A lantern comprising a casing having an opening in one end thereof, a shaft mounted for rotation within the casing and disposed transversely of the opening. a inenr ber having a rectangular cross sectional shape carried by the shaft, contact plates located upon said membe' and included in a normally opened circuit, electric bulbs carried by the pontact plates. a yieldable contact member also included in the opened circuit and adapted to close the circuit when engaged with one of the first mentioned contact plates and to yieldingly hold the shaft against rotation and means whereby the shaft may be rotated to project one of lhe bulbs through the opening and automatically close the circuit when the bulb is thus projected.

In testimony whereof I ailix my signature.

HAROLD C. BRECKENRIDGE.
