Serial No. 512,619.
This invention relates to improvements in fixture supports and more particularly to a combined socket and shade holder for electric lamps.
It is an object of this invention to provide a support which will not only ,act as a support for the socket of an electric lamp but also provide means for detachably securing a lamp shade as well. I
Vith this and other objects inview refer once is made to the accompanying sheets of drawings, which illustrate a preferred form of this invention, with the understanding that minor detail changes may be made without departing from the scope thereof.
In the drawings Figure 1 is a view in side elevation,- with parts broken away, illustrating one application of. this invention; 1
Figure 2 is a view partly in central vertical transversesection taken through Figure 1, more clearly indicated by the line 2--2 Figure 8, and partly in side elevation;
Figure 3 is an expandedview of the parts illustrated in Figure 2;
Figure .4; is a perspective view of the fixture support base in inverted position from that shown in Figure 1;
Figure 5 is a detail perspective view of the 1 socket carrying and shade engaging plate;
Figure 6' is a top plan view of'Figure 4;
Figure 7 is a view similar to Figure 6 illustrating the socket carrying and shade supporting plate in position thereon;
Figure 8 is a view similar to Figures 6 and? illustrating the assembled fixture support with shade and socket in place; and
Figure 9 is a fragmentary perspective View of the shade adapted to be attached to the support and illustrating the means upon the shade adapted for attaclnnent thereto.
In the embodiment of this invention as il lustrate-d. the fixture support comprises a base having a cylindrical portion 1 provided with a concentric socket receiving opening and an integral housing extending thereabove. The walls of the housing are extended to receive a hollow rod or other means of positioning the support, as in the manner shownin Figure 1. The exterior flat surface of the cylindrical portion 1 is provided with an annular groove 3 forming circumferential flanges 4e and 5 on each side thereof, the inner flange 5 being of greater width but of less height than the outer flange 4.,
An electric lamp socket of commercial type having oppositely disposedperforated attaching-ears 15 is secured to theplate 6 by screws 16 passedthrough the perforations and engaging the screw threaded apertures 17 provided therefor in the plate 6 and in order that the bottom of the screws do not strike the base, on account of irregularities in the formation of the cars 15, the flange 5 is provided with depressions 18o The shade to be employed with this sup port is provided with a cylindrical portion 19 having an inturned flange 20 at its upper end provided with oppositely disposed arcuate extensions 21 so proportioned that the shade maybe received within the annular groove 3 and upon rotation the extensions 21 will pass under the arcuate projections 11 of the plate 6 and ride upon the inclines 13 until the edges of the arcuate extensions 21 engage the posts 12. The inclines 13 are of such a degree that the portions of the shade extending therein will be firmly engaged by the yieldingly secured plate 6.
In electric fixtures of this type it is customary to pass the wiresthrough the hollow (ill rod and complete the connections to the socket Within the housing and it is for this reason that the wires and connections are not so shown.
It is obvious that a fixture constructed and assembled as shown and described above provides means for the ready attachment or removal of both socket and the shade or either, as the case may be. It is also seen that the removal of the socket in no way interferes with the means for holding the shade if it is desired to attach a shade to a socketless fixture. The posts 12 provide means for properly locating the plate 6 when assembling the socket, so that the screw 7 may be readily inserted in the screw threaded apertures 9. The post 12 possesses the additional function as acting as a stop when the shade is inserted within the annular groove and rotated for engagement with the plate. The provision of the inclines 13 upon the baseunder the arcuate projections not the plate and the provision of the springs 10 about the screws 7 not only is a means for compensating for irregularities in the thickness of the flanges 21 of the shade, but also provides a means which under all conditionswill allow the firm clamping of the shade in position. It is readily seen that by this construction a socket which becomes defective may be readily removed and replaced without detaching the shade holding means from thebase. It is also obvious that the fixturesupport may enter the housing at the angle shown or provision may be made to have the fixture sup port engage thehousing at any desired angle without departing from the scope of the invention. 7
