WITNESS INVENTOR y Br S /1'7ATT0RNEY-\ UNITED STATES PATENT OFFICE.
EDWIN F. GUTH, OF ST. LOUIS, MISSOURI,
LIGHTING-FIXTURE.
Application filed August 18, 1915.
To all whom it may concern:
Be it known that I, EDWIN F. GU'rH, a
citizen of the United States of America, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Lighting-Fixture, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to a lighting fixture, and its object is to produce a form of construction which will embody a minimum number of parts, and one which may be easily wired and assembled. In my improved construction the supply wires may be attached to the contact terminals before the fixture is assembled, or any part thereof is attached to the wall or ceiling, the terminals being carried on a separable part which may be easily placed and secured in position.
In the drawing, which is a sectional view illustrating my improved fixture, 1 represents the canopy, which is constructed of insulating material, such as vitreous china. This canopy bears against the wall or ceiling line 2 and is supported from the junction box 3 either by means of a strap 4 supported from the central stud 5 of the junction box, or by ears 6 of the junction box when these are provided. Screws 7 pass through the canopy and their threads engage with the threads in the strap 4., or with the threads in cars of the junction box, in which case the strap 4 may be omitted.
The canopy is provided with a threaded central opening into which a lamp receiving shell 8 may be screwed, this shell being provided with exterior as well as interior threads. The shell 8 is supported on the insulating base 9, which carries the contact terminals to which the supply wires 10 are attached A rubber Washer 11 may or may not be inserted between the base 9 and the canopy 1. In order to prevent the shell 8 from turning and therefore retreating out Specification of Letters Patent.
Patented Nov. 21, 1916.
Serial No. 46,097. I
of the opening in the canopy when the lamp is inserted, I preferably make the lower portion of the opening of the canopy wider than the remainder and thereby provide a shoulder 12. After the shell 8 is inserted its edge may be bent to engage this shoulder and thus prevent turning.
It will be noted that this fixture is of very simple construction; that the wires may be attached to the contact terminals on the base 9 and then the base placed in position in the canopy by screwing the canopy 011 the shell 8. Thus the whole fixture is wired and assembled prior to attaching it to the ceiling or other support.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. In a lighting fixture, the combination of a canopy provided with a threaded Opening, a socket member comprising a base of insulating material and an exteriorly and interiorly threaded lamp receiving shell permanently attached to the base and adapted to be screwed into the threaded opening in the canopy from the inside, and means for preventing the shell from turning when a lamp is inserted.
2. In a lighting fixture, the combination of a canopy provided with a threaded opening, and a socket member comprising a base of insulating material and an exteriorly and interiorly threaded lamp receiving shell per iuanently attached to the base and adapted to be screwed into the threaded opening in the canopy from the inside, a portion of the lower edge of the shell being bendable outwardly to engage the canopy and prevent the shell from turning when a lamp is in serted.
In tesb'mony whereof, I have hereunto set my hand and affixed my seal in the presence of the two subscribing witnesses.
