UNITED STATES PATENT OFFICE.
GEORGE P. FARR, OF VANCOUVER, BRITISH COLUMBIA, CANADA.
LAMP-BULB FITTING.
Application filed March 13, 1924. Serial No. 699,124.
To all whom t may concern:
Be it known that I, GEORGE P. FARR, a resident of the city of Vancouver, in the Province of British Columbia, Canada, and a subject of the King of Great Britain, have invented certain new and useful Improvements in Lamp-Bulb Fittings, of which the following is a specification.
My invention relates to improvements in lamp bulb fittings, the objects of which are first to provide a fitting which will partially obscure from general view the socket to which the lamp bulb is attached, second to provide a fitting which is artistic in form and eilect a semi-indirect lighting from the filament.
The invention consists essentially of a translucent bowl shaped body carried by the lamp bulb and a transparent cover for same, as will be more fully described in the following specification in which The drawing is a part sectional view of my invention.
The numeral 1 indicates a lamp socket into which a lamp bulb 2 is fitted. 3 is the filament by which illumination is obtained. 4L indicates generally the fitting which is formed with a bowl shaped lower P portion 5 and an inverted dished upper portion 6. The lower portion 5 is preferably formed of glass or other translucent ma* terial suitably ornamented, tinted and frosted on its outer surface 7 to suit any desired scheme of interior decoration and is smooth interiorly for the purpose of forming an upward reflecting surface 8. The lower portion 5 is apertured as at 9 that it may be carried by the lamp bulb 2 intermediately of the vertical length of the filament 3, though such is not essential. An
internal rim 10 is provided at the upper edge of the portion 5 for the purpose of receiving the periphery of the upper portion 6. The upper po-rtion 6- is of translucent material and is provided with a central aperture ll which loosely fits the base of the socket l.
Having thus described the several parts of my invention I will now briefly explain its use.
The inner-fitting of the upper portion 6 and the lower portion 5 enables the device to be loosely but immovably held in position on a lamp bulb of any desired shape. The lower portion of the lamp bulb used may be tinted to conform to the tinting of the device so that when the lamp is burning a diffused light is projected downwardly through the lamp bulb and radially through the lower portion 5 of the fitting. The light from the upper portion of the filament 3 is projected upwardly through the upper portion 6 of the body 4 and is also partially reliected from the smooth inner surface 8 of the lower portion so that the shadows usually cast by husks and other lamp bulb fittings are entirely eliminated and a soft leasant lighting is produced.
What I claim as my invention is: The combination with a lamp socket, of a translucent bowl shaped body apertured at its base to engage the lamp bulb intermediately of the vertical length of the lamp filament and inner reflecting surfaces to the body to direct the rays from a porti-on of the lamp filament upwards.
Dated at Vancouver, Bfl C., this 3rd day of March 1924.
