LAMP SHADE.

Application led January 5, 1925. Serial No. 523.

This invention relates to a lamp shade, lantern body or ornamental casing adapted to be illuminated from within, and the primary object of my invention is to provide a fabricated sheet metal structure in which translucent or transparent plates of various colors may be arrangedto imparta plea-sing effectto the exterior of the structure when illuminated from within.

Another object of this invention is to provide a simple, durable and inexpensive shade that may be easily and quickly attached to an incandescent lamp socket to in' close the lamp.

A further object of this invention is to provide a sectional lens holder wherein the sections of the holder are adjustable rela.- tive to one another to permit of a structure of desired figures being formed for supporting the lenses.

rlhe above and other objects are attained by the construction to be hereinafter speeifically described and then claimed and reference will now be had to the drawing, wherein:-

Figure 1 isa side elevation of a lamp shade partly broken away and partly in section;

Fig. 2 is a plan of the same partly in horizontal section;

Fig. 3 is a detail horizontal sectional view of a portion of a. modified form of casing;

Fig. 4 is an elevation of the same;

Fig. 5 is an enlarged detail sectional view of a joint or pivotal connection of parts of the casing shown in Figs. 3 and 4;

Fig. 6 is a side elevation of al lamp shade having a bottom wall, and

Fig. 7 is a bottom plan of the lamp shade partly broken away and partly in section.

The lamp shade is preferably made of a light and durable sheet metal skeleton frame and is preferably hexagonal in cross section so as to present a plurality of facets, but it is obvious that the shade may have a greater or lesser number' of facets or side walls: than shown and herein described. The shade body or framework has a plurality of large flat facets or walls 1 connected by small flat facets 2 and attached to these small facets, by nut equipped screws 3 are longitudinal channel retaining members 4 which are disposed on the inner walls of the facets 2 'so that lateral flanOes 5 of said retaininof members may extend) into parallelism with the large facets or walls 1 and provide a set of channel guides 6 on thek inner face of each n of the shade body or framework has an inturned channel edge 7 constituting a bottom holder or ledge for supporting the lowermost plate 8 of a series of superimposed plates 9 placed lin the channel guides 6 of the shade body. The plates 8 and 9 may be translucent or transparent, different colors, and in some instances may be in the form of lenses or suitably cut or molded ornamental bodies.

l The walls or facets 1 of the shade body are provided with parallel oblong openings ory slots 10 for exposing a portion of each of the plates 8 and 9 and with these plates suitably colored, for instance, colors of the rainbow, the exterior appearance of the shade body will be ornamental and highly pleasing to the eye. The plates 8 and 9 may be made to .suit ones esthetic taste and may be arranged in superposed relation, edge to edge, as shown in Fig. 1.

rThe lower end of the shade body is devoid vof a bottom wall and the upper end of the shade body has an inturned flange 11 to which is secured a top wall 12 by nut equipped screws 18 or other fastening means. The top wall 12 is formed with a depending flange 14 fitting against the facets r1 and 2 of the shade body, and the top wall 12 is provided with a central opening 15 affording clearance for the socket 16 of an incandescent lamp 17. Frictionally held in engagement with the top wall 12 of the opening 15 is a holder 19 of a conventional form by which the shade body is attach-ed to the lamp socket 16.

Instead of making the shade body or framework of a single piece of material I may use separate walls 2O and the longitudinal edges of said walls with rolled substantially tubular connecting members 21 that may be placed one within the other to form a frictional hinge between said walls so that the angularity of the walls may be changed or a large number of walls connected to form a. many sided shade body. Retaining members 22 are used in connection with the walls and as shown in Fig. 5 it is preferable to arrange the retaining members so as not to interfere with the frictional hinge between adjacent walls. The retaining members 2.2 are preferably in lorm of plates provided ivith oblong openings 23 corresponding somewhat to the Walls 2O so that the plates S and 9 may be placed between the walls 2O and the retaining members ne walls nia form the outer sides of the shade body or the retaining member en'iployed for this purpose, then again the arrangement may alternate as brought out in F 5. lilith the Walls and retaining members assembled as separate units the pates S may be placed in position and then the Walls connected so that there will be a sh; de body of desired shape.

In some instances the top wall l2 may be dispensed with particularly when the shade body is supported from its lower end around the lamp ot a pedestal, thus indicating that my invention is not limited to a suspended position relative to an imzandescent lamp.

Reference will nor: be had to Figs. 6 and 'T showing a lamp shade, generaliy'designated 2l and the side ivals or facets of this shade may have lens covered openings of rarions configurations, some of the openings being vertical, angular and horizontal, While other openings are circular, hexagonal, triangular or of other shapes which Will impart a degree of. ornamentation to the shade. T he lenses may be of soothing, relaxing' or such colors that may be beneficial in the treatment of body ailments.

rllhe lamp shade 24 may be provided with a bottom Wall 25 having openings 26 closed by lenses 27 which may be o't various colors.

The bottom Wall 25 is provided with a flange 28 that may be attached to the shade body by the nut equipped screws 3 Which hold the retaining members 4 Within the body.

llhilein the d awings there are illustrated the preferred embodiment of my invention, iti-is to be understood that the struc tural elementsare susceptible to such variations and n'iodifications as fall within the scope of the appended claims.

What I cl aim is l. A lamp shade comprisinga 'sheet metal body 'haring a set of' ivide facets and a set of narrow facets, and the Wide facets provided with a plurality ot' openings, superimposed colored plates arranged in said body against the wide facets thereof and at the openings ot said body, said body having a lower end flange supporting said super- `nosed plates, means attached to the narrow i'acets of said body to retain said plates in superposed relation therein, said body having an upper inturncd flange, and a top Wall fitted on said body and attached to the upper flange thereotI and adapted for supporting said body relative to an incandescent lamp in said body.

2. Alamp shade as called for in claim l, wherein said means includes retaining members against the narrow facets with lateral flanges ot said members disposed parallel to theivide lacets of said body.

In testimony whereotI I affix my signature.

WILLIAM FRISE.
