DANIEL W. F. DE GRANGE, OF BALTIMORE, MARYLAND.
IMPROVEMENT IN RAILROAD SIGNAL-LANTERNS.
Specification forming part of Letters Patent No. 213,812, dated April 1, 1879; application filed February 21, 1879.
To all whom it may concern Be it known that I, DANIEL W. F. DE GRANGE, of Baltimore, in the county of Baltimore and State of Maryland, have invented a new and useful Improvement in Railroad Signal-Lanterns, of which the following is a specification:
My invention relates to certain improvements in that class of lanterns which are in common use by railroad train-men and station-agents.
The object of my invention is to adapt the ordinary lantern for the double use of a white light and a colored signal-light.
The invention will first be described, and then designated in the claims.
Figure I is an elevation ofa lantern, showing a colored signal-glass attached to the oilfount. Fig. II is a view of oil-fount alone, showing the signal-glass in the transverse direction. Fig. III is a vertical section of the base of lamp. Fig. 1V is a perspective of signal-glass. Fig. V is an inverted plan of lamp-base. Y
The letter A represents the oil-fount, at one side of which I provide a vertical socket or groove, b, which receives the stem 0 of the signal-glass. This latter is a frame, d, in the present instance round, but it may be hexago nal or square, and incloses a glass of any desired color, such as red, green, or blue. A stem, 0, is attached to the frame, and in crosssection is flat, so as to avoid liability of turnin g in the socket or groove. This stem is bent, as shown atein Figs. II and IV, the purpose of which is to set the glass nearer the center of the oil-fount, where the diameter is greatest. By this means the oil-fount having the signal-glass attached may be inserted through the bottom of the lantern into the globe in the usual manner, and Withdrawn therefrom without difficulty.
The space F under the oil-fount is utilized as a receptacle, into which may be placed the signal-glasses when not in use. An annular plate, h, is secured into the base i, and is provided with a hinged cover, 02, having a suita ble fastening, r.
Thus an inexpensive receptacle is formed, which will be found very convenient for the purpose described.
Having described myinvention, I claim and desire to secure by United States Letters Patent- 1. A lantern oil-fount having at one side of that part which comes within the globe a vertical socket, in combination with a colored signal-glass provided with a stem having a bend, as set forth.
2. A signal-glass for a lantern, the frame whereof is provided with a stem, 0, having a bend, e, as and for the purpose set forth.
3. In a lantern, the receptacle F, formed under the oil-fount, and provided on the lower side with a hinged cover, substantially as set forth.
