HEAD-LIGHT FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 268,027dated November 28, 1882. Application led October 16, 188:2. (No model.)

To all whom it may concern:

Beit known that I, JOHN KIRBY, Jr., ofLudlow, Kenton county,State of Kentucky, have invented certain n ew and useful ImprovementsV in Head-Lights for Locomotives, Vof

which the following is a speeitication, referlence being had to the accom pauyin g drawings, forming part of this specification, in which- Figure l is a section on line x a; Vin Fig. 3. Io Fig. 2 is a view of head-light case, showing signal-box F and colored signal-globe E. Fig. 3 is a view-of head-light case, showing signalbox F, with colored signal-plate f audtnumber-platej'. Fig. tis a section showing ver- I 5 tical smoke-Hue G.

Similar letters of reference in the'several drawings indicate the same parts.

The object of my invention is to display signals or signal-numbers in the case of a headzo light for locomotives in such a manner that they may be seen from two or more sides. I accomplish this by constructing a case with a roof, C, whose top or cap is a box, F, and placing thereon transparencies, which may be 25 numbered or colored, or both. Acolored hollow glass cylinder, E, Fig. 2, may be displayed above said box F, illuminated by the same light that illuminates the transparencies. I prefer, however, to display number-signals 3o and colored signals in the box by placing the number-plates in the lower divisioinf", ot' the box F and the colored plates in the upper division, f; or the cclored plates may be placed in the lower division and the number-plates in the upper division.

The light't'or illuminating the signals cornes primarily from the lamp, the rays of which impinge on a relector, L, Figs. l and 3, placed beyond the month ot' the reflector K in the 4o rini N of the Case. This reector L is set so that the angle of incidenceof the rays ot' light from the lamp to the reflector is such that the angleot' reflection shall throw them directly into box F. a

To assist in getting the full strength of the light, I place a plate, A, of any suitable material, of a width not less than the width of box F, above the reector K, supporting it at one end near the front edge of reflector K, and at 5o the other on the edge of box F farthest from the reflector L. The edges of this plate may be turned up. This plate, with the side B of roof C, constitutes what I call a signal-light chamben7 and may be of any substance4 and color that tend to improve the light thrown 5 5' into box F. Plate A is shown, in Fig. 1 and in dotted lines in Figs. 3 and 2. This signallight chamber may be made in tubular form; but I prefer the form shown as more economical. The results of combustion in the lamp 6o are carried oft' by a vertical flue, Gr, Fig. 4, provided it does not pass through the box F, or may be carried oft' by 4a horizontal ue, H, Fig.v 1.

The box F may be closed at the bottom and illuminated by a lamp. In this event the reector L and plate A need not be used.

It will beseen by reference to the drawings that the box F is protected from the heat and smoke of the lamp, and that the signals are 7o not so liable to be smoked up as they are in lIead-lights in which they are placed on the sides ot' the open case and exposed to the smoke of a neglected burner. III this construction the smoke is practically shutout of the A box F.

It is difficult to see signals as ordinarily placed on the side of the rim of the case, from `in front, on account ot' the glare of light from the head-light reector. This trouble is obvi- 8o ated by placing the signals in box F on top of lthe roof C.

I do not claim broadly the placing of signals in the top of the case of a locomotive headlight. 8 5

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. A head-light case having a roof, C, divided' by a partition to form two chambers, 9o one a signal-light chamber and the other a chamber through which the products of combustion can pass to a suitable exit, as set forth.

2. A head-light case formed with aroof, C, having a signal-box above the partition-plate 9 5 A, lwhich plate extends from the rear of the box toward the f1 ont of the reflector, and an opening in rear of the partition-plate for the passage ofthe products ot' combustion.

The foregoing specication of my invention roo signed by Ine thisllth day of October, A. D. 1882.
