CHEMNEY AND REFLECTOR THEREFOR.

SPECIFICATION forming part of Letters Patent NO. 593,096, dated November 2, 1897.

Application filed March 19,1897. $eria1li'o. 628,336. (No model.)

To ctZZ whom it may concern.-

Be it known that I, OTTO HERRMANN, of Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Improvement in Chimneys and Reflectors Therefor, of which the following is a f ull, clear, and exact description.

The object of the invention is to provide a reflector for lamp-chimneys which will be supported directly from the chimney and maybe adjusted to different positions, the reflector being capable of throwing a much more bril- 4 liant light than reflectors of the ordinary con struction and stationarily located at the back of the chimney.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a section through the reflector and its bearing,talren substantially on the line 1 1 of Fig. 2, showing the chimney in side elevation. Fig. 2 is a front elevation of the chimney, a part being broken away, and a front elevation of the reflector mounted on the chimney; and Fig. 3 is anenlarged detail view of one of the bearings for the reflector carried by the chimney.

The chimney A may be of the ordinary or of any approved construction, and at opposite sides is provided with a bearingB, the bearing being of the same material as that of the chimney and preferably integral therewith. The inner surface 10 of the bearing is polygonal, as is particularly shown in Fig. 3. The reflector C is preferably also made of glass, and either its inner or its outer face is coated with mercury or any equivalent substance which will impart to it the properties of a looking-glass or which will afford a superior reflecting-surface.

The reflector is somewhat cup-shaped, its concaved surface being at the front, and the reflector is provided with a central opening 11., through which the chimney extends. At opposite sides of the opening 11 in the reflector trunnions 12 are formed, the inner end of each trunnion being made polygonal, as shown at 13 in Figs. 1 and 2. In fact, the exterior of the inner end of each trunnion is made to correspond substantially to the shape of the inner surface 10 of the bearings B of the chimney.

It will be understood that the polygonal surfaces 10 of the bearings are accessible from the top.

It is evident from the foregoing description that by lifting the reflector and shifting its position the reflector may be held in the position to which it is adjusted by simply turnin g the trunnions in the socket portions 10 of the bearings B. Areflector of the character above set forth can be attached to the chimney of an ordinary lamp and requires no back support, since it is carried entirely by the chimney, and, furthermore, by reason of the reflector being adjustable the light maybe thrown in any direction in the room or made to concentrate upon any object or surface.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A lamp-chimney having two bearings attached thereto, the bearings having angular seats designed to receive angular trunnions so that the trunnions may be held at various axial positions within the bearings;

2. A reflector having angular trunnions adapted to fit within angular bearings so that the reflector may be held at various positions by the engagement of said angular trunnions with the bearings.

3. The combination of a chimney and a reflector, the reflector being mounted on the chimney bymeans of angular bearings and trunnions whereby the reflector may be held at various posit-ions on the chimney by the engagement between said angular bearings and trunnions.

OTTO HERRMANN.
