FRAME non LAMP SHADES Application filed July 2, 1928; Serial No. 289,993.

My invention relates to the construction of a frame for detachable pleated lamp shades and has particular reference to the means used to attach the one to the other.

- sitates a pleated shade which must include notches and therefore is limited to such pleated shades as are provided with the notches. All shades of the pleated type do .not come provided with such notches, in fact few do have this feature.

With the foregoing in mind it. is the principal object of this invention to provide a frame which will accommodate any pleated shade, which may be securely attached to the frame without the necessity of having the pleats notched at their corners, and which may be readily detached from the frame and I accomplish this object by means of the 2 construction and arrangement hereinafter described, set forth in the appended claims and illustratively exemplified in the accompanying drawings, in which, Figure 1 is a side elevatlonal View of my improved frame,

the shadebeingshown in section; Figure 2 is a plan view of the frame and shade which is broken away in portions to further illustrate the arrangement of the two parts; and

- Figure 3 is a portion of the frame illustratinga modified means of securing the shade to the frame. I

Referring to the drawings, 10 denotes a frame commonly used in connection with electrically equipped lighting fixtures to support a shade 11. The frame 10 in this instance is preferably conical in form and comprises an upper wire ring 12 and a lower wire ring 13, the latter of course being substantially larger than the upper ring 12.

below the highest point of the ring 17 In These rings are spaced apart and are provided with inclined spacing rods 14 arranged circumferentially about the rings 12 and 13, to which they are permanently attached at their ends by means of solder. The upper ring 12 is supported by, a lamp bearing 15 by means of radially projecting, bars 16 permanently secured at their ends tothe, ring 12 andlamp bearing 15.

Thus far I have described a frame of the usual construction which will support the usual lamp shade without providing a means of detachably connecting the one to the other. In accordance with the present invention I permanently secure to each spacing rod 1 1, preferably adjacentto ring 12, a hook member 17, which according to Figure 1 comprises a ring having a portion cut away to provide a gap 18', the gap in each case being arranged Figure 3, the wire or rod 14 is bent back upon itself to form the downwardly directed hook portion 19.

The lamp shade 11, as I have stated, may be of any of the well known pleated types, 7 constructed preferably of a strip of stiff textile or paper material which has been pleated transversely of the strip and which is further provided with a series of holes 20. The holes 20 arrange themselves in a circumferential line when the ends of the pleated strip have been attached together and are so disposed in the pleats 21 thus formed, as to be on a plane with the upper portions of the hooks 17 or 19. The usual cord 22 passing through these holes 20 and alternately spanning the spaces, first on the inside and then on the outside, between the inclined sides forming the pleats, is hooked under a hook 17 or 19 wherever they occur on the frame.

It is clear that by thus hooking the cord 22 under the hooks the covering will be held snugly to the upper and lower rings 12 and 13 and at its midportion to the straight portions of the spacing rods or wires 14. To remove the shade or covering 11 it is simply necessary to unhook the cord 22 from each hook and lift the covering off the frame.

Having now fully described my invention and the manner in which the same is applied what I claim as new and desire to secure by Letters Patent is: v V

1. A lamp shade, comprising a pleated covering, a frame therefor having upper and lower spaced closed members, spacing pieces arranged circumferentially of the rings and integrally attached-at their ends to the latter, each spacing piece having an outwardly disposed and downwardly directed integral hook portion.

2. A lamp shade, comprising a pleated covering, a frame therefor having upper and lower spaced rings, the latter being larger than the former circumferentially arranged spacing rods secured at their opposite ends to the upper and lower rings respectively and an integral hook carried by each spacing rod and directed'outwardly to engage over the band at the, inner periphery of a covering,

3. A lamp shade, comprising a conical pleated covering having a binding cord running through the pleats and alternately appearing on opposite surfaces of the covering, and a frame for the inside of said covering comprising an upper ring and a larger lower ring spaced apart, inclined rods arranged circumferentially of the rings and integral at' opposite ends with the latter, and a downwardly directed hook for each rodto engage over the cord at certain places where it enters the inside of the covering.

In testimony whereof he has affixed his signature. 1
