WILLIAM WHEELER, OF CONCORD, MASSACHUSETTS.

REFLECTOR FOR STREET LAMPS OR LANTERNS, 840.

SPECIFICATION forming part of Letters Patent N 0. 268,063, dated November 28, 1882.

Application filed June 6, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WHEELER, of Concord, in the county of Middlesex and State 'of Massachusetts, have invented a new and verse section, on an enlarged scale, of one of the metallic fillets or beaded bands used for holding in place the series of glass reflectingplates applied to the inner surface of the shell of the reflector. Fig, 7 is a transverse section, on an enlarged scale, showing the arrangement of such fillet, with the shell, its flange, and a glass reflecting-plate. Fig. Sis an under side view of a portion of such fillet. Fig. 9 is a vertical and longitudinal section of the reflector.

The nature of my invention is defined in the claims hereinafter presented.

In the drawings the reflector is exhibited as having four conical or approximately conical reflecting-surfaces,arranged as shown, two of them-via, the upper and lower ones, a and b.being convex semi-frustums, while the others or intermediate ones, a and d, are concave semi-frustums. YVithin the reflector, and concentric with its lower reflecting portion, a, is an open chamber or socket, A, for holding an oil or kerosene lamp, B, in its proper position relative to the said reflecting-surfaces. Over such chamber or socket, and in the upper portion of the reflector, is an opening, 0, for the glass chimney I) of the lamp to extend through, allbeingsubstantially as represented. At the lower part of said opening there projects from the reflector a hook or stud, e, which, with the front part of the opening, serves to support the chimney on its being raised into the positionshown in Fig. 5 to admit of the lamp being removed from the reflector and trimmed without the necessity at the same time of removing the chimney therefrom. To prevent accidental breakage or injury to the lamp-chimneys, they are frequently left in the street-lanterns while the lamps are taken or are away therefrom for being trimmed or supplied with oil. The object of the hook or stud, arranged as described, will thus be apparent.

The shell E of the reflector has narrow flanges h h, extending from it at its inner and outer edges, bounding the series of reflecting glass plates In. There is arranged within and against each of the said flanges a flexile metallic fillet, I, having on' its inner surface, and lengthwise thereof, a bead, m, such beaded fillet being represented in transverse section in Fig. 6. These fillets I usually make of lead. After having been soldered at one edge ofeach to its supporting-flange h, the fillets are to be bent down upon andover the glass reflectingplates at their ends, which are to abut against the beads, each head serving to prevent its.

fillet, when bent down, from having or presenting a corrugated or angular outline on its outer surface, as it would be liable generally to have Without such bead.

Instead of having the head in one piece with the rest of the fillet, I sometimes make it in a separate piece.

With a reflector made as described rays of light from the flame of the lamp will be refiected laterally in opposite directions from the parts or reflecting-plates in rear of the lamp, while from those iii-front of and above the lamp the rays will be thrown or reflected in divergent lines.

. My present invention has special reference to reflectors for use with common lamps for tric lights or carbon pencils therefor.

What I claim as myinvention is as follows, viz

1. The reflector as constructed with the two convex conic reflecting-surfaces a b, the two concave conic intervening reflecting-surfaces c d, the chimney-opening O, and the lamp oilreservoir-receivin g socket A, arranged substantially as set forth.

2. The reflector as constructed with the two convex conic reflecting-surfaces a b, the two intervening concave conic reflecting-surfaces c d, the chimney-opening G, the chimney-supporting hook or stud e, and the lamp-reservoirreceiving socket A, as and arranged substantially as set forth.

3. The reflector-shell provided with flanges and reflecting-plates arranged between them,

and with metallic fillets and beads or metallic beaded fillets, essentially and arranged with :0 the said flanges and reflecting-plates as set forth.
