LAMP SHADE HOLDER Filed July 10, 1955 v INVENTCR, MLTa/v C Ev ATTORNEY.

Patented Dec. 31, 1935 UNlTED STATES PATENT OFFICE 10 Claims.

The invention relates to shade-holders of the type which are employed in indirect-lighting devices, each having a standard on which an illuminating device is mounted.

Surrounding the illuminating device, which usually is an electric-light bulb, is an inverted porcelain or glass reflector which, not only directs certain rays of light upward, but operates to diffuse through its wall other rays of light which are reflected downward by a shade that surrounds said reflector.

These porcelain or glass shades are very fragile, and, in order to protect them from being broken, it has been the practice to either surround the body of eachshade with a protective element, or to provide its upper edge with a protective ring of rubber or other shock-absorbing substance.

According to the invention, hereinafter described, such a protective ring isso faShioned as to serve the further purpose of supporting another part of the device which may be fixed thereto,.but, preferably, is separable therefrom. In the preferred embodiment of the invention, said other part of the device is a metal shade.- supporting ring frcrn which a shade may be pendently supported and held firmly in place.

The invention will be better understood if reference be had to the accompanying drawing, in which- Figure 1 is a View in elevation of the shade holder, parts of the shade being broken away to reveal the shade holder in section;

Figure 2 is a plan view of the shade holder;

Figure 3 is an enlarged view showing a part of the shade holder in elevation;

Figure 4 is a sectional view taken on the line 44 of Figure 3;

Figure 5 is a fragmental view showing in elevation a modification;

Figure 6 is a sectional view taken on the line 66 of Figure 5;

Figure 7 is a view of a further modification, partly in section, and

Figure 8 is a view of a grooved strip which may be bent to circular form and used as a part of the shade holder.

Referring to the drawing, I is a standard such as is commonly used in floor lamps. This standard supports a lamp socket 2 carrying an electric bulb 3, as shown, and also a retaining ring 4 for a primary reflector 5 which may be made of glass or other suitable light-reflecting or light-difiusing material, and held in position by a set screw 6.

Surmounting said primary reflector 5, is a ring 1 of rubber or other flexible material, which has a groove 8 on its under side into which fits the upper edge of said primary reflector 5, thereby adapting said ring 1 to be easily applied to and removed from said primary reflector. When in place o aid efle t 5. a d fl x ble ri 1 protects saidprimary reflector from shocks which it may encounter while being packed ;for shipment and while in transit, or in use.

Removably sustained by said flexible ring 1, is

a metal ring 9 which carries a secondary reflector or shade .I ll, the upper edge of which is secured to said metal ring 9 in any suitable manner, as by curling said upper edge aroundsaid metal ring and securing it thereto by an adhesive.

As shown in Figures 1, 2, 3 and 4, said ,flexible ring I is provided with a plurality of upstanding spaced lugs ll, each having acrevice l2 terminating in a hole [3 for receiving one of a number of radially-disposed arms IA, the outer end Ma of each of said arms being fixedly secured to said metal ring 9, while its inner end ldb is secured to a metal element l5 carrying ornamentation l6.

Proximate the outer ends Mu of said arms 14, are detents H, which engage the inner surface of flexible ring Into thereby maintain the concentrici y of s id ib e ing land a d me a in :9,- These detents, however, may be omitted provided the frictional engagement of said arms with the flxible ring 1 is sufficient to hold said flexible ring I and said metal ring 9 in proper relation to each other.

The modification shown in Figures 5 and 6 includes the grooved flexible ring 1, the primary reflector 5, the metal ring 9, and a plurality of short rods l8 each having, if desired, a detent I9. Each of these rods [8 extend through a hole 20 in said flexible ring I, and is fixedly secured to said metal ring 9 at its outer end.

The modification shown in Figure '7 comprehends outstanding arms 2! each carried by the grooved flexible ring I, and being suitably attached at its outer end to the metal ring 9.

Figure 8 shows a straight and grooved piece of flexible material, such as rubber, which may be curved to the circular form shown in the other figures. This straight strip may be provided with the lugs II and crevices I2, shown in Figures 1, 2, 3 and 4, with the holes l3, or with any other adequate means for fixedly or separably securing the metal ring 9 thereto when it is bent to circular form. This strip, however, initially may be a ring which is molded or otherwise produced.

From the foregoing description, it will be seen that the grooved flexible ring operates not only to protect the frangible inverted reflector from shocks, but constitutes a support for the shadesupporting element 9, such as it may be, and regardless of Whether said shade-supporting element is a ring, or is a support of some other available form, or even lacks continuity.

The flexible protective ring I should be made of heat-resisting material, so that heat from the source of light will not impair its resiliency.

Furthermore, should the device be knocked over and the reflector broken, the protective ring 1 will hold the fragments together and prevent them from cutting the hand of a person who might carelessly pick them up if strewn upon the floor, Also, said protective ring 1 prevents such chipping of the upper edge of the reflector 5 as would initiate a crack in its body portion.

Having thus described my invention, what I claim is:

1. A shade-holder including in combination, an inverted primary reflector, and a ring having a groove in its under side into which the upper edge of said primary reflector extends, said ring having means on its upper side for holding a shade-support in a predetermined relation to said reflector.

2. A shade-holder including in combination, an inverted primary glass reflector, a shade-support, a shade, and a ring of resilient material having a groove in its under side into which the upper edge of said primary reflector extends, said ring having on its upper side depressions for centralizing and holding said shade support in a predetermined position relative to said reflector and said shade.

3. In combination, an inverted translucent frangible reflector, a rubber ring having a groove in its under side into which the upper edge of said reflector extends, spaced creviced lugs on the upper side of said ring, and a metal shade-supporting ring having arms which frictionally engage the crevices of said lugs.

4. A shade-holder, including a primary reflector, a ring having a groove in its under side into which the upper edge of said primary reflector extends, a metal ring surmounting the grooved ring, arms extending through the grooved ring and secured at their outer ends to said metal ring and a shade supported by said metal ring.

5. A shade-holder, including a primary reflector, a ring having a groove in its under side into which the upper edge of said primary reflector extends, a metal ring surmounting the grooved ring,

the grooved ring, radially-disposed arms secured 15 to said metal ring and resting in said crevices, and a secondary reflector or-shade secured at its upper end to said metal ring.

7. A shade-holder, including an inverted reflector, a ring having a groove in its under side into 3 which the upper end of said primary reflector extends, a metal ring disposed about the grooved ring, arms uniting the grooved ring and the metal ring and having bends engaging the grooved ring for holding the grooved ring and said metal ring in their relative positions and a shade supported by said metal ring.

8. An article of manufacture constituting a part of a shade-holder, and comprising a strip of rubber having a groove in one side thereof, and provided with spaced holes extending laterally therethrough for the reception of arms which are parts of said shade-holder.

9. An article of manufacture, comprising a rubber cushioning element having in its under side a groove for engaging the upper edge of a glass reflector, said element having also means for attaching a shade-holder thereto.

10. As an article of manufacture, a rubber element for protecting the edge of glass reflectors,

said element having a groove on one side into which'the upper edge of the glass reflector may extend, and having also means for attaching a shade support thereto.
