Application filed January 2'7, 1902. Serial No. 91,466. (No model.)

To all whom it may concern:

Be it known that I, ALFRED CHARLES BUNNE, a citizen of the United States, residing in New York, borough of Manhattan, in

5 the State of New York, have invented certain new and useful Improvements in Signal-Lanterns, of which the following is a specifica tion.

This invention relates to certain improvements in signal-lanterns for railway, trolley, and other cars, stations, &c., the object of the invention being to provide means by which the color of the light can be changed from white to red or green, so as to overcome I 5 the necessity of a separate lantern for each color and reduce thereby the number of labterns required for signaling purposes; and the invention, consists in the combination, in a signal-lantern, of a lamp, casings above and below said lamp, a wire guard-frame connecting said casings, telescoping globes, one in each casing, and means for placing either the upper or lower telescoping globe in posi tion around the lamp; and the invention 0on sists, further, in certain details of construction and combinations of parts, which will be fully described hereinafter and finally pointed out in the claims.

Inthe accompanying drawings, Figure 1 is 0 aside view of my improved signal-lantern, both globes being in this view withdrawn into their casings, the lanterns in this case emitting ordinary white light. Fig. 2 is a vertical central section through the lamp with the globes in the same position as in Fig.

1. Figs. 3 and 4c are also vertical central sections, respectively, with the upper globe lowered and with the lower globe raised. Fig. 5 is a horizontal section on line 5 5, Fig. 3; and

0 Fig. 6 is a bottom view of the lantern.

Similar-letters of reference indicate corresponding parts.

Referring to the drawings, A represents the oil font or lamp proper, and B the chimney,

5 which maybe of any desired shape and which is made of ordinary uncolored glass and retained in position between a flange a. of the housing of for the oil-font A and flange a of the perforated chimney-cap a The housing ct is attached in any suitable manner to the may be withdrawn.

lower casing G, which casing comprises a perforated outer wall or shell 0 and a bottom 0, closing the casing at or near the lower end. The cap a is attached in any suitable manner to the upper casing D, which comprises a perforated wall or shell d, to which is hinged at d a top or cover d closing the casing at its upper end. The cap a is shown attached to the cover (1 and extending partly within and partly without the same and pro- .vided at its exterior part with perforations for exit of the products of combustion from the lamp. The cover is normally retained in closed position by asuitable spring-catch, one member (1 of which is attached to the casingwall d and the other member d to the cover (1 The casings C and D are rigidly connected by means of vertical guide-rods,of which two, 6 and 6, arranged diametrically opposite each other, are shown, and by means of a guardframe E, of the usual construction, extending at one side of the lantern, unbroken at the outer side of the rod e, and at the other side terminating at each side of the rod e, so as not to cover said rod, but leave the same unobstructed, so that a guide-sleeve e can be readily slid by the user of the lantern up- Wardly or downwardly on said rod e.

For retaining the oil-font A in its housing a a spring a of suitable strength is secured at one end to the bottom 0', at its lower side, and retained normally in position across the bottom of the oil-font A by means of two keepers a and a To remove the font, the spring is released from the open keeper a by the user and moved into the position indicated in dotted lines in Fig. 6, when the font The bottom 0' is preferably provided with a suitable downwardly and outwardly projecting flange 0 the whole being detachably secured to the shell. 0 by a bayonet-joint c and catch 0 or other suitable means.

Upon the guide-rod e is arranged a sleeve 6 to which and to a guide 6 on the opposite rod e is connected a ring e supporting the lower member 6 of a globe F, the upper members e e of which are adapted to telescope one within the other and all within the member e, and the latter with the others adapted 1 :0 to enter within the upper casing D, so as to be obscured when not in use. The uppermost member 6 is provided at diametrically opposite points with guiding projections 6 permitting movement of the member vertically in the casing and limitingits downward movement-and the downward movement of the entire globe by abutment at the lower end of the slots 6 the members of the globe being connected each with and dependent from the next by means of suitable top and bottom flanges, as clearly shown in the drawings. The globe is ofsuch size as to be moved up and down freely at the outside of the chimney B and is of such length as when completely extended to cover the entire eX- posed portion of the chimney, so that the light given by the lantern is entirely of the color of the globe. The individual members of the globe may be made of glass, celluloid, or other sufficiently transparent durable material. To the guide-sleeve e is attached a suit-able hook or link, which when hooked over a projection 12 on the guide-rod e or other suitable point of support maintains said sleeve in raised position, and thereby the entire globe in telescoped state within the casing.

The lower globe G is constructed, in a manner similar to the upper one, of telescoping members 12 b b b, of which the lowermost is connected by any suitable means, as pins 1)", projecting from supports 5 with the casing O, and the upper largest member 19 is guided by means of guides b and 6 connected with a supporting-ring b on the rods 6 e, the guide e being made in the form of a sleeve and forming the main guide, the lower globe being extended or telescoped by the user when the upper globe is in raised position by sliding this sleeve e upward or downward on the rod 6. The sleeve is provided with a suitable spring-latch b adapted when the globe is raised to engage a notch b of the rod e and retain the globe Gin raised position, the lantern in this case giving light of the color of said globe.

To the upper casing is pivoted a suitable bail d For facilitating the operation of raising the upper globe from lowered or extended into telescoped position a suitable telescoping mechanism is provided, which is preferably connected with the bail. This mechanism, as shown, consists of a leverf, pivoted at one end to the guard-frame E and connected at its opposite end by means of a link f with the guide 6 of the globe. At an intermediate point is connected by a suitable pin-andslot connection f an operating-rod f which is guided in a suitable sleeve secured to the casing D, said rod extending in upward direction and being guided at its upper portion by sleeves f f on the bail d. The rod f is articulated at two points in its length f f respectively, and said guide-sleeve f of the casing, together with the other parts, are so constructed and arranged that when the globe is in raised position one of said ara lamp,

ticulations is adjacent the pivot f of the bail, and when lowered the other articulation is in position adjacent the said pivot, so that in either case the bail is not of necessity retained alwaysin upright position,which would be the case were the rod f not so articulated; but the bail is thereby permitted to fall into the customary position at either side of the lantern when notin use. The upper end of the rod f is preferablyhooked or looped, as atf, for conveniently grasping the same. By this mechanism the upper globe, which will customarily be red in color, can be operated with the greatest facility and retained conveniently by the user in raised position for any desired time without hooking the link b over its projection. When said link is hooked over its projection b, not only is theglobe retained in raised position, but the operatingrod also is retained with the articulation f in position for permitting falling of the bail into downward position when the lantern is set down. Furthermore, the bend of the operating-rod at its articulation when the bail is in downward position serves to retain the globein raised position even though the link be not hooked over its projection Z).

The lower member of the globe G need not be formed of transparent material and is preferably of such width as not to project above the casing-wall c.

The articulations f f are preferably doubly articulate by means of the short links shown to provide for slight play of the parts.

In the lantern shown the globe descends by gravity when released, the operating-rod serving for raising the same. By swinging the bail to one side, releasing the catch d d, and swinging the cover (1 into open position the chimney can be removed and access had to the interior of the globes for cleaning. When the sleeve (2 is in lowermost position, the spring-catch 12 engages a notch I9 of the rod 6, thereby retaining the lower globe G securelyin telescoped condition within the lower casing.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a signal-lantern, the combination of a casing, and a globe formed of a plurality of individual members or sections arranged concentrically within each other, each section connected at one end with the next inner section and at the other end with the next outer section, and each section of less width than the distance from said casing to the flame of said lamp, said sections when extended in succession extending to and at the sides of said flame, substantially as set forth.

2. In a signal-lantern, the combination of a lamp, casings, one above and one below the flame of said lamp, and a globe formed of a plurality of individual members or sections arranged concentrically within each other, each section of less width than the space between said casings and each section connected at one end with the nextinnersection and at the other end with the next outer section, said sections when extended in succession closing the space between said casings, substantiall y asset forth.

3. In a signal-lantern, the combination of a lamp, casings, one above and one below the flame of said lamp, a globeforined of a plu rality of individual members or sections arranged concentrically within each other, each section of less width than the space between said casings, and each section connected at one end with the next inner section and at the other end with the next outer section,

said sections when extended in succession closing the space between said casings, a bail connected with one of said casings, and an operating device connected with said globe and bail, substantially as set forth.

4. In a signal-lantern, the combination of a lamp, casingsabove and below said lamp,

a guard-frame connecting said casings, guiderods within said guard-frame and protected thereby, a telescoping globe in each casing,

means for moving one of said globes into position inclosing said lamp and means for moving the other of said globes independently into position inclosing said lamp, substantially as set forth.

5. In a signal-lantern, the combination of a lamp, lower and upper casings, telescoping globes in said casings, guide-rods connecting said casings, a guard-frame also connecting the casings, and located outside of the guiderods, a bail, a lever mechanism connected with the upper globe, an articulatedoperating-rod connected with said lever mechanism and guided on said bail, and means for looking the upper globe in raised position, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

ALFRED CHARLES BUNNE.
