M. M. MARKS. LIGHTING FIXTURE.
APPLICATION FILED FEB. 28, ISIS.
"1,334,623. Patented Mar. 23, 1920.
' the following is a speci cation.
MYER. M. MARKS, or crncaeo, ILLINOIS.
LIGHTING-FIXTURE.
Specification of Letters Patent.
Patented Mar. 2-3, 1920.
Application filed February-28, 1919. Serial No. 279,885.
7 '0 all whom it may concern Be it known that I, Mrnn M. MARKS, a citizen of the United States, residing at Chi cago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lightin -Fixtures, of which,
My invention relates to lighting fixtures such as are described in Patent No. 1230046, which fixture employs a reflector and a diffusing globe to shield the eyes from the direct rays emitted by the filament of the electric lamp and has for its object to construct an improved holder or support for holding the reflector and globe in position.
My means of accomplishing the foregoing object may be more fully understood by reference to the accompanying drawings which are hereunto annexed and which form a part of this specification in which:
Figure 1 is a vertical sectional view of a lighting fixture of the character referred to equipped with my improved holder.
Fig. 2 is an enlarged sectional view of my improvement.
Fig. 3 is a detail bottom plan view of my improved holder.
Fig. 4 is a perspective view partially in section of my improved holder.
Similar reference numerals refer to similar parts throughout the entire description.
As shown in the drawing, the cap or holder 10, which is preferably formed of metal, and which may be provided with a suitably threaded opening 11 at its upper end for the convenient suspension ,of the lighting fixture has a vertical cylindrical wall 14: at its lower end. Mounted within this wall is an annular member 15, which may be secured to the holder in any desired or. convenient manner. The annular band 15 has secured to it at predetermined intervals, a plurality of downwardly depending metal strips 16, the ends 17 of which are adapted to engage the lip 18, formed on the neck 19 of the globe 20. -The metal strips 16 are engaged by a ring 21, preferably formed of spring-steel, the ends 22 and 23 of which are bent downwardly and outwardly to engage the lower edge of the annular band 15, which is provided with a plurality of teeth 24.
A plurality of to the band 15,
metal strips 25 are secured the ends 27 of which are shaped to engage the lip 28 on the neck 29, formed upon the reflector 30.
A ring 31, of spring wire corresponding to the ring 21, is secured to the downwardly idependmg metal strips 25, its ends 32 and 33 ,being shaped so as to engage teeth 34,
1 ,formed on the lower edge of the band 15*.
The fixture is assembled in the following manner:
The neck of the reflector is inserted in the holder until the lip is engaged by the ends 27 of the metal strips 25. The ends 32 and 33 of the ring 31, are then drawn toward each other until the neck of the reflector is firmly clamped by the ends of the metal strips 25.
The ends are then inserted intermediate the teeth 34 when it will be apparent that the reflector will be held securely in position. The neck of the globe is then passed through the reflector and up into the holder until the lip engages the end 17 of the metal strips 16, when the ends 22 and 23 of the ring 21, are drawn toward each other until the neck of the globe is securely held. When the ends 22 and 23 are inserted intermediate the teeth 24, the tension of the spring wire serves to hold them securely in position.
It will be apparent from the foregoing de scription that by this construction I entirely eliminate all screws for holding the reflector and globe in position. Thus not only providing a more secure holding device but greatly improving the appearance of the outside of the fixture.
Having described my invention what I regard as new and desire to secure by Letters Patent is:
1. The combination with a holder of a globe and reflector each having a lip formed at their top, a band mounted in said holder adjacent its lower end, a plurality of strips of metal secured to the inner surface of said band in the plane of the lips of the globe and reflector respectively, said strips being shaped to engage the said lips, spring wire attached to said strips, adjacent their point of contact with the lips the ends of said wire extending downwardly and engaging teeth formed on the edge of the band, whereby the strips may be held in engagement with said globe and reflector.
2. The combination with a holder of a globe and reflector each of which has a lip formed at its neck, a. plizlu 7 strips secured to said holder a geee ntits lower end, said strips being shaped to engage the lips on the globe afidfefiector respectively and means to hold said strips in engagement With the said lips.
3. The combination with a holder of a, globe and reflector each of which has a lip formed at its neck, a plnraglitg of metal strips secured to said holder adjacent its lower end, said strips being shaped to engage the lips on the globe and reflector respectively, rings attached to said strips, ad-
' their point of contact with the globe and reflector and means to detachably hold 15 said rings in a contracted osition.
4. The combination W1th a holder of a plurality of metal strips, a band mounted in said holder to which said strips are secured, a globe and reflector each of which has a lip formed at its neck, said metal strips being shaped to engage the lips on the globe and reflector respectively and means to hold said strips in engagement with the said lips.
