To all whom it may concern: sectional plan on the line we: of'Fig. 1. Fig.- Beit known thatLFREDERICK WJDRESSEL, 3 is an inverted plan of the disk, and Fig. 4 acitizen of the United States, residing in the is an elevation of the disk and handle by borough of Manhattan, city, county,and State which the lamp-body is rotated. 4 5 of New York, have invented an Improvement a represents a lamp-bod y, preferably made in Signal-Lamps for Railway-Oars, of which of sheet metal and conveniently square in the following is a specification. Y cross-section. The lamp -body is provided My invention relates to railway signalwith frames 1 2 3 4, secured in openings and lamps, and particularly to rotatable signal- 1 adapted to receive different-colored lenses. 60 to lamps placed on the topsof carsand adapted b represents the cover of the lamp-bodya,

to be turned horizontally in either direction and cl its base. I provide a tubular cylinlfrom within thecars; and the sameis'aniim dricalsupport d-,the lower end of which is proveinent upon the device shown and deformed at an inclination and provided with scribed in Letters Patent No."570,156, granta flange (11, adapted to be connected to the 6 -15 ed to O. H. Dressel, October. 27,1896. In the roof is ofa car or caboose in any desired mandevice of this patent the lamp-body was supner,with an intervening washer of waterproof ported by a ring providedwith feet or legs material. The upper end of the support 61 secured to the roof of the car or caboose and i has an inturned flange 01 and the base of the operating-rod simply passed through the l the lamp-body fits within this inturnedfiange 7o roof.

My present invention relates and catch-plate 6, and the inturned, flange d especially to devices for overcoming these of the support is provided with notches 7. A "e 5 difficulties, to means for holding the light disk Z, in diameter agreeing with the interior stationary within the rotatable lamp-body, diameter of the support d, comes close to the and to means for shutting the light 0d from under surface of the flange (Z and this disk all but one of the number'of lenses which the is connected to the base a and plate 0' by lamp-body may contain. means of bolts 8, which also secure the spring 3'0 In carrying out my invention I employ a 5 and catch-plate 6 in'place. A rod 9 is conlamp-body provided'with suitable lenses of nected at its. upper end to the diskl and exdifierent colors, atubular cylindrical suptends down through the tubular support (1 port of cast met-a1 having one'end formed at to the interior of the car and terminates in a an inclination and flanged for connection to handle 10, by which the rod' and lamp-body 35 the roof of a car or caboose and the other and arerotated. The rod 9 is fitted with a disk upper end with a notched inwardly-extendm, preferably divided into quadrant surfaces i'n-g flange, the said lamp-body being con- 11, 12, 13, and 14:, which are colored correnected to and fitting rotatably within the said spondingly to the colors of the respective support and there being a connection from lenses and which in position upon the rod 9 go do the said lamp-base to the interior of the car come directly below the lenses of. correspondf'or rotating the lamp-body. I also employ a ing colors in order that the light being used stationary cap covering --the lamp-body and as a signal may be indicated from the interior connected to thesupport for thelight or lamp of the car. Some of the parts heretofore deemployed within the lamp-body, and a sta scribed are the same as those shown, de- 5 1' 5 tionary shield is secured to the lamp-support, scribed, and claimed in Letters Patent No. which shield: extends partially around said 584,110, granted June 8, 1897, to O. H. Dressel. lamp and shuts off the light from all but one The stationary lamp-support comprises an of the lenses in the lamp-body, the shield also elbow e, a tubular connection 15, which exacting as a reflector. tends to and is secured in the roof of the car, Ice 50 In the drawings, Figure 1 is a vertical secand a tubular extension 16, secured to the tion illustrating my invention. Fig. 2 is a elbow e. The cover of the lamp-body has a p raised integral portion 17 and a plate 18, and centrally between these parts a sleeve 19 is employed, and these parts are preferably connected by solder. The extension 16 passes through the parts of the cover I) and the sleeve 19, and the position of the extension 15 at its free end is determined thereby and vertical movement prevented by a nut 20, the lower part of the extension 10 being adapted to receive a lamp-socket 72-.

9 represents a shield partially surrounding the lamp contained in the socket 7b. The shield is provided with an integral top 21 and may be securely held in place by passing over the extension 16, between the nut 20 and the lampsocket 7L; but I prefer to permanently connect the nut 20 and shield together.

j" represents a cap which is secured to the elbow e and fits over the raised portion 17 of the cover I) to make the lam pbody both water and dust proof. One of the sides of the lampbody may be conveniently provided with a door 1', by which access to the interior of the lamp-body is easily gained for the purposes of changing lamps or cleaning the reflector.

In the operation of the structure the extension 15, elbow a, tubular part 16, shield g, nut 20, socket h, and lamp remain stationary and fixed, while the lamp-body, with the colored lenses, changes position as rotated by the rod 9 and handle 10, the position of the lampbody being determined by the relative position of the colored disk m, as hereinbefore described.

I claim as my invention- 1. In a railway signal-lamp adapted for use on the roofs of cars, the combination with a fixed support, of a revoluble lamp body mounted thereon and adapted for varicolored lenses, means for rotating the lamp-body and for determining its several positions, a cover for the lamp-body having a tubular portion forming a guide, a stationary support for an incandescent or other lamp or light secured to the roof of the car, a tubular extension thereof passing through the top of the lamp and means supported thereby within the lamp-body for directing the light through only one of the lenses thereof at a time.
