SHADE HOLDER.
I Application filed January 8,1924. Serial No. 684,973.
My invention relates to lighting fixtures and more particularly to shade holders for In shade holders of this type, it is desirable to provide a structure which consists of a small number of manually adjusted parts in order that a single operation com plete an assembly of large or otherwise cumbersome units. It is also necessary that the parts be capable ofquick adjustment and in such manner that certain fragile units of the assembly are not so tightly retained as to cause breakage. I
It is, therefore, an object of my invention to provide a shade holder which shall elliciently hold the shade and globe.
It is a further object of my invention-to provide a structure which shall be easily and quickly adjusted and which shallretain the shade and globe in a sufiiciently rigid manner without causing breakage because of an excessive or unequal pressure at some particular point on the shade or globe.
It is a still further object of my invention to provide a structure which shall be manually operable to quickly assemble the parts.
Iitherto. a, holder has been provided in which the shade was attached to the lamp socket by means of a friction band which was tightened by a threaded bolt. In another, form, the globe was held in place and suspended from a number of screws. Such arrangements required several operations and adjustments to bring all the parts to gether. The structure was also objectionable for use with large shades because it required a cumbersome holder. It was objectionable for use with large globes because the globes broke at the points of suspension.
My invention is directed to a structure adapted to hold either a shade or a globe or both. It is so arranged that there is multiple point suspension. The shade and globe holders are actuated by a single manual means and the tension of the holder is also adjusted by the same means.
Specifically, I provide an arrangement consisting of two parts, a fixed ring and a movable ring. The fixed ring consists of a flange attached to the bell or husk of the fixture, and a threaded portion secured thereto surrounding the lamp socket. The flange is provided with bayonet slits which receive pins attached to the shade. The
movable ring comprises a flange and a threaded portion which is receivedby the threaded port-ion of the stationary ring. The globe is supported by the flange of the movablev ring. lVhen all the parts are brought together the assembly is completed by screwing the movable ring into the stationary ring by the aid, of projections or finger holds ou'the movable ring.
In the accompanying drawing constituting apart hereof and in which like reference characters designate like parts,
Figure 1 is a view, partially in section and partially in elevation, of my shade holder assembled with a globe and shade;
Fig. 2 is a sectional view showing the parts of Fig. 1 in more detail;
Fig. 3 is a view similar to Fig. 2 and illustrates a modification in which theshade is rigidly attached and the globe is loosely attached;
Fig. 4 is a similar view and shows the application of the holder to a shade which is supported by a bracket; I
Fig. 5 is a plan view of the flanged ring shown in Fig. 3; a
Fig. 6 is a plan view of the ring and shade supporting arms Fig. 7 is a plan view of the fixed flange showing the-bayonet slots therein, and
Fig. 8 is an elevational view of the movable ring.
Attached tothe hell or husk 1 of the fixtures is a fixed flange 2 which has a threaded portion 3 formed at its inner edge. Bayonet slots 4; are provided in the flange 2. The movable ring 5 has a threaded portion 6 and projections or finger holds 7 to manually operate the ring 5. The pins 8 may be attached to the shade 9 at diametrically opposed points.
In use, the shade 9 is attached to the fixture by inserting the pins 8 into the bayonet slots i. A slight rotary movement then retains the pins and shade. The operator then supports the globe 12 on the movable ring 5 and the threaded portion (5 of movable ring 5 is screwed into the threaded portion 3 of the fixed ring. The assembled parts are brought together with the desired tension by means of the projections 7 which are attached to the movable ring.
In the modification shown in Fig. 3, the pins 8 are mounted on the independent ring 10, which may or may not be integral with the shade 9, the said ring having a clownwardly extending flange 14.. In this instance, the movable ring bears against the independent flanged ring and holds the shade rigidly in place and the independent flanged ring forms a space or groove next to the movable ring in which the shade is held. The movable ring is therefore screwed in far enough to produce the desired compression on the shade 9. The globe 12 is supported in the groove 13 and the compression on the globe is regulated only by the depth of the flange 14:.
The manner of attaching a parchment shade is shown in Figs. l6. The shade 15 and the arms 16 are attached to the ring 11. The pins 8 in the ring 11 cooperate with the bayonet slots in the flange 2 so that the shade is suspended while the globe is being inserted or removed.
It will be noted that my invention provides a structure which is easily and quickly assembled. The structure consists of a small number of parts acting in such a manner as to reduce breakage by preventing an excessive or unequal pressure at any particular point on the globe. Pins in the shade memher and bayonet slots in the husk member temporarily retain the shade member when the globe is being inserted or removed and a threaded keeper ring holds both the shade and globe to the husk member in peri'nanent adjustment.
.[ claim as my invention:
1. A shade holder comprising a canopy and two co-operating threaded members in said canopy, means for suspending a shade from one member and means in the other member for supporting a globe and for securing said shade, globe and canopy together.
2. A shade holder comprising a canopy and two co-operating threaded members, one of said members being fixed to said canopy, slotted means in said fixed member for sus pending a shade and a threaded flange in said other member for co-operating with said fixed member to secure a shade, globe and canopy together. v
3. A shade holder comprising a canopy having a stationary threaded member having slots in a portion thereof, a removable threaded member, pins for suspending a therein having bayonet slots for engaging pins in a shade, an inner upturned threaded member on said flange, a keeper ring provided with a threaded portion for inwardly engaging said upturned threaded member, and a flange on said keeper ring for engaging a globe and for securely uniting said globe, shade and canopy.
6. A shade holder comprising a movable member adapted to be screwed into a stationary member, a flange on said stationary member, bayonet slots in said flange adapted to co-operate with pins in a shade for suspending said shade and a flange on said movable member cooperating with said flange on the stationary member and with the said shade for rigidly holding the shade and rotatably holding the globe.
In testimony whereof, I have hereunto subscribed my name this 17th day of Dec. 1923.
JOHN R. TOlVNSEND.
