IMPROVEMENT IN REFLECTORS.

Specification forming part of Letters Patent No. 139,923, dated June 17, 1873; application filed December 17, 187,2. i

To all whom it may concern.'

Be it known that I, FAUNT LE ROY SENOUR, of Newport, Campbell county, Kentucky, have invented certain new and useful Improvements in Reilectors, ot which the following is a specification The nature of my invention relates to an improvement in locomotive head-lights and it consists in the arrangement and combination of parts, which will be more fully described hereafter.

Figure 1 is a vertical section, showing my improved reflector as applied to a locomotive head-light 5 and Fig. 2 is an enlarged diagram, showing more clearly the shape ot' the corrugations, the casing or envelope being omitted.

A represents a boX or frame such as is generally employed for a locomotive head-light, and the rear side of said frame is provided with a door, B, which, when opened, affords access to the rear of the relector. The front of this box is furnished with the customary glass door or Window O. Secured Within this box is a plate, D, having an inwardly-projecting annular ilange, d, which ilange serves to support the outer or ilaring end ot' the glass reilector E; .This glass reilector has two apertures, F Ff, drilled or ground through it, which apertures are for the reception of the lampchimney. The external surface of the glass is silvered, as shown at G, for the purpose of increasing its reilecting properties. After the open end of the reflector has been tted around the annular flange d, I then surround said reilector with a jacket, casing, or envelope, Il, which is composed of any suitable cement or plastic material. This envelope becomes so hard when dried as to anchor the 'reilector securely Within the trame or box, and at the same time it preserves the silvered surface G. The

jacket also prevents fracture of the reflector.

I represents the lamp, and J the chimney of the sume, both of which may be of any approved construction.

As previously stated, the reflector may be either blown or pressed, and, if produced by the latter operation, the holes F F may be made Without either drilling or grinding.

I have described my reileetor more especially as adapted for head-lights but it is evident that it may be used for street-lamps and many other purposes.

The silver on the back of the glass may be omitted and the proper reilecting properties obtained by means of a polished metallic hood that could be arranged around said glass.

I claim as my invention- The reflector of a locomotive head-light anchored within the case A by the cement backing H and ilanged plate I), or its equivalent device, substantially as shown and described.

In testimony of which invention I hereunto set my hand.

FAUNT LE ROY SENOUR.
