EUGENE ALEXANDER SIMPSON, OF MORRISTOWN, TENNESSEE, ASSIGNOR OF ONE-HALF 'IO CHARLES HICKS AND ALFRED J'. TETER, BOTH OF CHATTANOOGA, TENNESSEE.

SIGNAL-LANTERN.

Application filed December 23, 1915.

To all whom it may concern:

Be it known that I, EUGENE A. SIMrsoN, a citizen of the United States, and a resident of Morristo-wn, county of Hamblen, and State of Tennessee, have invented certain new and useful Improvements in Signal- Lanterns, of which the following is a specification.

My invention relates broadly to illumination and more particularly to a signal lantern.

The primary object of my invention resides in the provision of a device of the above character embodying transparent means for association with a base of a light source and movable at times to surround the light source and consequently change the color of the light displayed.

Another object of this invention resides in the provision of novel means for mounting the transparent means or colored shade, so as to reduce friction to a minimum during the operation, novel means being also provided for operating the shade to either raise the shade so that it surrounds the light source or to lower the shade topermit the latter to lie within the supporting sleeve and consequently permit of the light source being displayed in its usual manner.

Another object of this invention resides in the provision of novel means for associating the operating means with the body of the lantern so that the colored shade can be expeditiously actuated eXteriorly of the lamp body and frame.

Another object of this invention resides in the novel means for associating the transparent means and other parts cooperating therewith on the standard lamp body which can in turn be removably associated with the standard frame.

Another object of this invention resides in the improved means for mounting the wick operating means so that it can be readily engaged on the bottonr-of the lamp body.

A still further-object of my invention resides in the provision of a device of the above character that is simple in construc tion, eflicient in operation, and one that contains but a few simple parts that can be cheaply manufactured and assembled, and when assembled can be placed upon the market and sold at a minimum cost.

Other objects as well as the nature, charac- Specification of Letters Patent.

teristic features and scope of this invention will be more readily understood from. the following description taken in connection with the accompanying drawings and pointed out in the claims, forming a part of this specification.

Referring to the drawings :Figure 1 is a vertical sectional view of my invention associated with a portion of the standard lamp frame, showing to advantage the arrangement of the colored chimney when in its lowermost position. Fig. 2 is a side elevational view of my invention showing the transparent chimney in a raised position. Fig. 3 is a transverse sectional view taken on line 33 of Fig. 1, in the direction in which the arrow points. Fig. 4 is a bottom plan view of my invention. Fig. 5 is an enlarged vertical sectional and fragmentary view of a modified form of transparent chimney. Fig. 6 is a fragmentary side elevational view of the body, illustrating a means for connecting the body to the frame.

Referring more particularly to the drawings to which similar reference numerals designate like and corresponding parts throughout the various views, I associate with a standard lamp frame including guarding and supporting bars 1, to which is connected a cylindrical supporting casing 2 for the usual chimney 3, my improved lamp base generally designated a, connection being preferably provided through the medium of oppositely disposed outstanding lugs 5 which engage oppositely disposed recesses 6 in the annular base, and connnunicating slots 7. A leaf spring 8 has one end secured exteriorly of the annular base while the opposite end is provided with an opening for removable engagement with one of the lugs for locking the lamp body in position. It is to be understood that this connection means constitutes no essential part of my invention, being merely illustrated and described in order that a thorough understanding and comprehension of my invention may be gained.

In mounting my invention on the lamp base, the bottom of the base is provided with a central raised portion 9, and rotatably and centrally connected thereto through the medium of a bolt 10, is a circular metallic plate 11, the outer edge of said plate being arranged in close relation with the shoulder provided by the raised portion. A nut 12, serves to support the plate during operation while an annular band 13, soldered or otherwise connected to the bottom of the base, holds the plate in close relation with the bottom and reduces rattling to a minimum.

Centrally disposed upon the upper surface of the bottom of the base is an oil receptacle 141-, to the top of which is connected a wick supporting closure cap 15, the light from which is normally viewed through the chimney 8 when the device is complete. In order to surround the light and display a light of a different color, I have provided my impiroved transparent means. In arranging the transparent means within the base, a metallic sleeve 16, is mounted on the upper surface of the bottom in spaced relation to the receptacle l-it, through the medium of an inwardly extending flange 17, integral with the sleeve and soldered to the bottom. Rotatably on the bottom exteriorly of and in close relation with the sleeve 16, is another metallic sleeve 18, the movement of which is guided by a flange 19, formed by bending the upper edge of the sleeve 16, out wardly upon itself. The sleeve 16, is further provided with oppositely disposed and diametrically slanting slots 20, which are arranged in an opposite direction to the oppositely disposed diametrically slanting slots 21, in the sleeve 18, for a purpose to be described. An annular channel shaped member 22, hereinafter termed a shade-carriage, is slidably arranged within the sleeve 16, and projecting through and extending from diametrically opposite points in the said member are studs 23, which are also arranged-through the slots 20 and 21, as is illustrated to advantage in the drawing. The lower portion 24:, of the channel shaped member is wider than the upper portion and serves to support the transparent means, in the present instance, a colored glass shade 25, which is removably locked in the channel shaped member through the medium of outwardly projecting and integrally formed studs 26, receivable within registering slots 27, in the upper portion of the channel shaped member. It will now be apparent when the outer sleeve 18, is rotated the lugs 23, will be raised by the slots 21 and 20, and guided by these slots until the studs reach the upper ends of the slots and consequently raise the shade 25, so that it surrounds the light source and causes a red light to be dis played.

For the purpose of rotating the outer sleeve 18, I have soldered or otherwise secured the shank 28, of an operating element to the lower surface thereof, said shank being arranged in a semi-circular slot 29, in the bottom of the base and in an opening 30, in the plate 11. An operating handle 31, is formed by looping the free end of the element upon itself, said handle being soldered or otherwise rigidly connected'to the plate so as to rotate therewith.

For the purpose of raising or lowering the wick without disconnecting any of the parts, I have rotatably mounted the lower end of a rod 32, in an opening in the bottom and in a semi-circular slot 33, the opposite end of the rod being rotatably mounted in an angular bracket 34, rigidly connected to the upper surface of the oil receptacle 1 1. A gear 35, is rigidly connected to the upper end of the rod and in mesh with a similar gear 36, rigidly mounted on the projecting end of the wick operating staff 37, the latter in turn, being supported by the bracket 34. A knurled element 88, formed on the lower end of the rod facilitates the rotation of the rod.

In Fig. 5, of the accompanying drawings, I have illustrated a modified form of transparent means. In this instance I have provided a cylindrical frame-work including an annular band 39, from which project the studs 40, and vertical supporting bars ll,

integral with the band. This frame-work supports arcuate pieces of mica 4:2, or like material of any desired color.

The operation of my invention is as follows z-Assuming that the transparent shade 25, is in a position as illustrated in Fig. 1, and that it is desired to raise the shade to surround the light and consequently display a light of a difierent color, the handle 31, is engaged and turned so that the shank 28, will slide through the slot 29, in the bottom and rotate the plate 11. During this movement the other sleeve 18, to which the shank is connected will rotate and cause the studs 28, to be moved and guided upwardly through the medium of the oppositely arranged slanting slots 21 and 20 arranged respectively in the outer sleeve 18, and the inner stationary sleeve 16. Since the shade 25, is connected and supported on the channel shaped member 22, the said sleeve will be raised simultaneously with movement of the handle 31. It will be understood that the rod 32, will move in the slot 33, when the plate is, rotated. To lower the shade 25, it is only necessary to reverse the movement of the handle 31.

Although I have shown and described the preferred form of my invention it will be understood that I am not to be limited to the exact details shown, however, I desire that great stress be laid upon the arrangement of the novel shade, as Well as the oppositely arranged slots in the stationary and movable sleeves for lifting and guiding the shade during operation. Attention is also directed to the novel arrangement of the operating means for the shade and for the wick which can be manipulated without disconnecting any of the parts.

From the above description taken in connection with the accompanying drawings it can be easily seen that this invention provides a device that is simple in construction containing but a few simple parts that can be cheaply manufactured and assembled and when assembled can be placed upon the market and sold at a minimum cost.

Having thus fully described this invention What is claimed and desired to be secured by Letters Patent is 1. The combination with a pair of concentric sleeves provided with oppositely extending diagonally arranged slots and a shade carriage operable thereby, of a base stationarily carrying one of said sleeves and having a shoulder formed thereon, and a plate on said base for peripheral engagement with said shoulder, said plate being operatively connected with the other of said sleeves to insure even movement of the second said sleeve when in operation.

2. The combination with a base having a pair of relatively movable sleeves thereon provided with oppositely extending diago nal slots and operating means therefor, of a shade carriage comprising a channelshaped ring having one peripheral wall thereof extended to provide a base flange for supporting a shade, and a pair of pins extending from said ring at diametrically opposite points for engagement with the slots in the sleeves for the purpose specified.

In testimony whereof, I have hereunto set my hand this 1st day of December 1915.

EUGENE ALEXANDER SIMPSON.
