LANTERN FOR ELECTRIC OR OTHER LIGHTS.
SPECIFICATION forming part of Letters Patent No. 687,738, dated December 3, 1901. Application filed December 8, 1900. Serial No. 39,146. (No model.)
To all whom it may concern.-
Be itknown that LJOHN O. FLEM1Ne,a citizen of the United States, residing at Summit, in the county of Union and State of New J er- 5 sey,have invented certain new and useful Improvements in Lanterns for Electric or other lilights, of which the following is a specificat on.
My invention has relation to a lantern for incandescent and other lights, and in such connection it relates to the construction and arrangement of parts constituting the lantern and fixtures therefor.
The principal objects of my invention are, first, to provide a lantern for electric or other lights comprising a plurality of transparent or translucent devices in the shape of shells, a tube or standard traversing the inner device, a series of lights adjustably supported on said tube or standard at or near the base provide a means whereby the lights within 5'0 plate,
the inner device or shell may be withdrawn without disturbing the main parts of the lantern and for the purpose of repairing or replacing the lights.
The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in Which- Figure 1 is a Vertical central sectional View of a lantern embodying the main features of my invention. Fig. 2 is a perspective view of the cage or bracket adapted to support the lower end of the devices. Fig. 3 is an underneath plan view of the lower grooved ring in which the ends of the devices or shells are located. Fig. 4 is a horizontal sectional view taken on the line a: a"; of Fig. 1. Fig. 5 is an underneath plan View of the upper circular and Fig. 6 is a vertical central sectional view of the lantern with a modified form of reflector.
Referring to the drawings, a represents the tube or standard forming the conduit for the wires leading to a series of incandescent electric lights b,grouped around thestandard near its lower end. The exposed portion of the tube a is coated or covered with white enamel to prevent absorption of the rays from the lamps b. The upper end of the standard or tube a is fitted in a suitable support or socket a, fixed to the ceiling or other horizontal support. Below the support or socket a the standard or tube a is screw-threaded, as at a for a purpose to be hereinafter described. The tube atraverses the inner of two concentric shells d and 61, preferably of conical form, the upper edges or rims of which fit in the grooves of a circular plate 6. The lower edges of the shells cl and d also fit in a similarlygrooved ring e. The shells d and d are formed of glass or similar transparent or translucent material, and the space between their contiguous walls is adapted to be filled with a translucent liquid (1 of any suitable color or consistency. The upper plate 6 has a central eye or bush 6 adapted to slide on the tube a, over the screw-threaded end a of said tube, and when in position is locked against upward movement by a jam-nut e adapted to bear against the bush e when advanced on the screw-threaded portion a of the tube 0.. The lower ring 6 is supported in position by a basket or cage e consisting of a plurality of vertically-disposed arms a, the upper ends of which enter suitable grooves or sockets e in the under face of the ring e. These arms 6 project at a slight angle upward from a skeleton plate 6', having a central boss 9 fitting around the tube a. The plate e and its arms are adapted to be locked to the standard a againstdownward movement thereon by a jam-nut a", hearing against the boss 6 In assembling the shells and the two clamping-supports together the shells d and d are first fitted into the grooves of the plate e and then the lower ring 6 is fitted against the lower rims of the shells d and d'. and the basket or cage 6 advanced on the tube or until it fits against the ring e, when it is clamped by the nut e". The upper plate e is now clamped down upon the upper edges or rims of the shells d and d by advancing the jam-nut e on the tube or standard 0;. XVhen thus locked together, the interior lower portion of the two shells may be readily reached by inserting the hands through the openings bet-ween the arms 6 The lights I), as illustrated in the drawings, are preferably incandescent electric lights, although other kinds may be employed, and the bulbs are inserted in a series of sockets b, radially projecting from a collar b This collar b is adapted to he slid up or down upon the tube a and when in proper position may be locked to said tube by a setscrew 17 or other suitable means. To prevent the light from the lamps b radiating downward through the base of the lantern, there is preferably supported upon the tube aabove the collar b a dish-shaped reflector-plate b the interior of which is coated with white enamel orother suitable material. The plate or dish 11 surrounds the bulbs of the lamps, as clearly illustrated in Fig. 1, and its base is perforated, as at 17 to permit the lamps to be drawn downward through the base of said dish 12. To prevent the entrance of air, dust, or moisture into the interior of the lantern through the cage 6 a protectinghood f, adapted to surround the ring e" and basket or cage 6 is provided. This hood f projects upward from a cap-piece f, having a screwthrcaded socket f adapted to receive the screw-threaded end a of the tube or standard a. Whenever it is necessary to have access to the lamps Z), the hoodfand cap f are first removed from the tube a and the hand of the operator inserted through the cage 6 to reach the set-screw b and to loosen the same. The collar b sockets b, and lamps b may then be drawn down into the cage 6', the bulbs of the lamps readily passing through the apertures b in the base of the dish I). The lamps b may then be unscrewed from their sockets and replaced. The collar 11 is then elevated and locked in its proper position. The hood f and capf are then looked to the tube a, and the lantern is in condition for use. To properly reflect the rays of light through the shells cl and d, a concave reflector 9 may be used, as illustrated in Fig. 1, or in lieu thereof a conical inverted reflector g, as illustrated in Fig. 6, may be substituted. WVhen the concave reflectorg is used, it is provided with a central screwthreaded opening or bush g adapted to engage the screw-threaded portion a of the tube or standard a slightly below the plate 6. WVhen the conical reflector g is used, its apex is formed with a collar or bush 9 adapted to be secured to the tube or standard a in any suitable manner at a point adjacent to the lamps b.
Having thus described the nature and objects of my invention, what I claim as new,
and desire to secure by Letters Patent, is-
