SPECIFIGATION forming part of Letters Patent No. 640,374, dated January 2, 1900.

Application filed March 2,1899. Serial No. 707,453. (No model.)

To (tZZ whom it may concern:

Beit known thatl, JOHN C. FLEMING, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful 11nproveinent in Reflectors for Electric or other Lights, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to an improved construction of a reflector for electric and other lights whereby I am enabled to intensify the light which would ordinarily be wasted, provision being further made forlighting the ceiling or upper part of the room or apartment in which the reflector may be located.

To the above ends my invention consists of a tube upon which the upper and lowerlights are supported, said tube carrying an upper reflector for reflecting light upon the upper portion of a room, and a lower reflecting-plate below which is supported a plurality of concentric cones, the outer of said cones being of glass and the inner of said cones being coated with white enamel or other reflecting medium, the top surface of the upper reflector, as also the bottom surface of the supporting-plate iherebelow, being also coated with enamel or similar material.

It also consists of the novel means for enabling the parts to be readily assembled and disconnected for the purpose of inspection or repairs.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a vertical sectional view of a reflector for an electric or other light embodying my invention. Fig. 2 represents a bottom view of the top plate employed. Fig. 8 represents detached sectional views of the upper reflector and top plate and the lockingbolt therefor, showing the parts in the act of being assembled. Fig. i represents, on an enlarged scale, a sectional View of the upper portion of the reflector in assembled position. Fig. 5 represents a side elevation of the plate below the upper reflector. Fig. 6 represents a sectional view of the lower locking device of the reflector in detached position. Fig. 7 represents a plan view of a plate located between the lower conical locking device and the concentric cones.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a reflector, the same being suspended from the tube or fixture B, which is secured to the ceiling or upper portion of the apartment in any suitable manner, said tube containing the conductors O, the lower extremities of which appear in the lower portion of Fig. 1, the same being contained within the pipe or tube D, which latter is supported from the pipe B by means of the coupling E, so as to form a continuation thereof.

F designates a plurality of electric or other lighting devices, the same being mounted on suitable supports and being connected in any suitable manner to the conductors C and located above the upper reflector or plate G, the same being secured to the tube D, preferably by means of screw-threads or other similar device, said plate consisting of the body portion II, the upper surface of which is provided with a coating or layer of white enamel J or similar material, whereby the rays of light from the lamps F will be effectively diffused and thrown against the upper portion or ceiling of the room or apartment in which the reflector is located.

K designates a plate which is located be neath the plate G and is of lesser diameter, said plate K being slipped upon the rod D and screwed thereupon at the point L and being provided at its under portion with the inner and outer concentric grooves N and I, in which latter is situated the upper portion of the outer conical shell Q, which latter is preferably constructed of glass or other similar transparent material.

R designates an inner conical shell which is composed of metal or other similar material and has its upper end seated in the groove N, the exterior of said cone B being lined or provided with a coating S of white enamel or other similar material possessed of great reflecting powers. The lower portions of the cones Q, R, and S are seated in the concentric grooves T and U, which are located in the upper surface of the plate V, the latter being supported on the lower locking-cone \V and being screwed upon the rod D at X. The under side of the plate V is in contact with the locking-cone W, which has the threaded socket Y, which is screwed upon the lower end of the tube D, the outer walls Z of said cone being in contact with the outer under'portion of said plate. The outer surface of the lower locking-cone is provided with a coating of white enamel or other suitable reflecting material and has a threaded socket A in its lower portion for the reception of the tube B, which carries the light 0, to which one of the conductors 0 leads.

D designates openings in the socket Y through which certain of the conductors 0 lead, said conductors being connected to the lamps E, which are supported upon the tubes F, which are secured to the cone W. The top of the plate K is provided with the keepers G, through which pass the bolts H, the ends of the latter passing under the inwardlyprojecting flange J of the upper deflector K, the manner of assembling the parts vbeing clearly understood from Figs. 3 and 4. The under side of the upper deflector K is pro vided with a coating K of white enamel or other suitable reflecting m aterial, which is also placed upon the concave annular shoulder L in order to evenly distribute the light.

In the space between the concentric cones I pour a suitable liquid, which will assist in the reflection of the light and also make it more agreeable to the eye, said liquid being poured in through the opening M.

It will be understood that the outer cone can in practice be constructed of plain, corrugated, or fluted glass, as may be expedient. I may also, if desired, dispense with the use of a liquid and paint the inner surface of the outer cone Q with any suitable reflecting material, or, if desired, the outer cone may in some instances be dispensed with.
