To ail whom it may concern Be it known that I, VVILLiAM KELLEY, of the city of Baltimore, in the State of Mary-v land, have invented certain new and useful Improvements in Signals for Locomotive Head- Lights; and I do'hereby declare that the following is a full, clear, and exact description of my invention, which will enable others skilled in the art to'whicli it appertains to make and use the same, reference being had to the ac conipanying drawings, and to the letters of-referen'ce marked thereon, which form a part of this specification.

My invention relates to a signal which may be exhibited, as desired, at the head-light of a locomotive, to indicate that the train is immediately followed by another, or as a danger- .signal, or for other purposes.

The invention is designed to be usedns either a day or a night signal; and consists, first, in combining with the headlight lantern colored front and side glass plates, the projeetin rim or flange holding the glass of the lantern being provided with side openings or windows, through which a diffused light is thrown from the interior of the lantern for the purpose of producing sidc signals. lleretofore side signal-lights have been obtained through opcningseut in. the respective sides of the lantern and parabolic refiector,thc light having been thrown directly through said openings, or reflected from the respective inner concave surfaces of the reflector. 0onsiderahle trouble and expense attend such a construction, and besides at the openings cut in the reflector dark spots are shown. I. have fcnnd by experience that a diil'nscd light is equally as well adapted for effecting the side signals as a directly-reflected light; and the first part of my invention to produce an lights to be shown.

The invention consists, fourthly, iu oertain mechanical. details whereby the framed colored glass plates mentioned in the above description of the second part of my invention may be moved to and from the. face of tlie lantern.

In the accompanying drawings, Fignrel is a perspective view of the head-light lantern, in which the framed colored glass plates aforesaid are shown in their two positions-viz., in front of the lantern and removed therefromthe latter adjustment being shown in dotted lines, as will be readily understood. Fig. 2 is a vertical section. through the projecting rim or flange of the lantern, showing the side openings and glass plates fixed over the same.

Fig. 3 is a perspective view of a detail of the invention, hereinafter described.

Similar letters of reference indicate similar parts in all the views.

A is the headlight lantern. B B are redglass plates, inclosed in frames a a. The

frames at a are hinged or leavcd together at c. The pair of frames are hinged to the lantcrn'at c. The plates 13 form the front signals, standing when in position in front of the lantern-nice, as shown in Fig. '1 by the full lines, the plates 13 forming at the-same time the side signals, and occupying positions ov'er the windows cut, respectively, in the two sides of the rim or flange b. The said windows are surrounded by frames 0, soldered to the rim or flange b, the framesc extending out to the sides of the lantern. The windows are'covcred by glass plates 0 fixed over the same.

0 G are rods, loosely connected to the frames a by means of the pins d. The rods (J are bent to right angles at c, and when the signalplates B B are at the front parts of the lantern have the position shown in Fig. 1, being hooked at the notches 0 over the stops c". When, however, the sight:

to the position shown in the said figure by dotted lines, the notch 42' is fitted to a stop. similar to c", situated at the back of the lantern.

-It will be understood that the hinge a"-allows the plates B B to be brought flat against the sides of the lantern, as shown by the dot. ted lines in Fig. 1'.

plates for the purpose of allowing side signalh l'atps are moved 1 in, 3 shows a standard provided with a front and a side signal-plate, secured thereto. This may be used by simply inserting the lower end of the standard in a socket formed in the baseboard of the lantern. The construction shown in Fig. 1 is, however, that preferred by me, by reason of its greater convenience.

The upper sections of the frames receiving the glass plates are hinged,-and the plates slipped into the frames, as shown and claimed as of my invention in my Letters Patent No. 207,284, dated August 20, 1878. The present invention is designed for application to such head-light to which the invention described, in the said Letters Patent would be inapplicable, and also to furnish a side light, not provided for in my said former invention.

In this invention, as in my said former one, the glass plates serve as a day or anight signal, the color of the frame-work being made to corres 'ioiid with the color ol'the plates.

The chief advantage attending the use .of

Ithis improvement is in the great saving to the,

railroad company using it of lamps of diffenf ent kinds and the oil necessarylto supply them. For signals of different significations, glass plates of different colors may be used, in aceordanee with the rules governing railroadsignaling.

I claim as new and wish to secure by Let-- tors Patent of the United.S tates- 1. A head-light lantern having its frcnt prc. jecting rim or flange provided with side openin gs or windows, combined with colored-front and side glass plates, substantially as and for the purpose specified.

2. A head-light lantern having its front projecting ri'tn' provided with side openings or windows, combined with colored front and side glass plates united or hinged together,

and adapted to be placed in front of said lantern and over the side windows thereof and removed therefrom, substantially as and for the purposes specified.

3. Combined with a head-light lantern haw ing its front projecting rim provided with side openings or windows, colored front and side glass plates, hinged or leaved together, and

5. Combined with a head-liirht lantern having its front projecting rim or flange laterally perforated, as described, frames e and glass.

plates c' fixed therein, substantially. as set forth. I

6. The headlightlantern A, combined with the plates B B. and rods 0 U, the said plates being hinged together and to the lantern, sub-- stantially as specified.

7. The head-light lantern A, plates B B', bent rods 0 C, notehedas described, and stops 0'', all combined substantially as specified.

1n testimony whereof I aflix my signature hereto in the presence of two subseribi iglwit messes this 2d day-of January, 1829,

WILLIAM KELLEY.
