LAMP SHADE.

Application filed June 19, 1921.1..

To aU 107mm it may concern:

Be it known that I, LESLIE H. BURLIN, a

citizen of the United States of America, andv ent improvement has for its various ob- J To provide a structural formationv and combination of parts and features, whereby a substantial attachmentbetween the pliable main portion and therigidv supporting ring or rings of a lamp shade is attained in a rapid and economical manner.

To provide a combination of parts in. the sectional rigid supporting` frame or. rings ofV a lamp shade, whereby a tensioning of the pliable and ornamental portion of the shade is attained in a ready and substantial manner.

To provide a formation and combination of parts whereby the pliable ornamental lining of the rigid skeletonV crown member Y of the supportingframe is attached thereto in a substantial and convenient manner, all as will hereinafter more fully appear.

In the accompanying drawings:

Fig. 1, is a plan view of a lamp shade to which the preferred form of the invention is applied. Y

Fig. 2, is a side elevation, with parts ofv the superimposedy layers of fabric, etc., broken away and removed to disclose underlying parts.

Fig. 3, is an enlarged fragmentary section of the completed shade.

Fig, 4, is a fragmentary section ofthe upper and lower rigid members or rings of the supporting frame, and showing the means for eii'ecting an adjustment between the saine.

Fig. 5, is a detail elevation of a portion of the lower ring member of the supporting frame.

Like reference l numerals indicate like Y parts in the several views.

As' shown in the drawings; therigidsupi Serial No. 720,991.

porting frame or member of the lamp sha-de, preferably comprises a lower annular ring` l of a circular, elliptical or otherl 'usual shape, and an ripper annular ring 2 of a corresponding shape, and which is preferably connected by an intermediate skeleton web 3 with a central. attaching collar oi" hub fi hereinafter described. The intermediate web 3 being preferably of a dome shape as shown.

In the present improvement the frame rings'l and 2 are provided with peripheral holding grooves or channels 5, and in the preferred, construction suchA grooves 5 are formed by spaced rows of lugs 6, arranged in4 staggered relation on the periphery of the rings, as' shown more particularly in Figs. 2 and 5, with a view to the ready molding` of theV same when made by casting. The connecting means between the frame rings l and 2 is of the expanding type in order to attain the hereinafter described tensioning of the pliable lamp shade member, and preferably comprises a plurality of stay rods 7, the upper ends of which rest in sockets formed therefor in the under surface of the upper frame ring 2, while the lower ends of said stay rods rest upon adjusting screw plugs 8 having adjustment in a plurality of screw-threaded orifices in the lower fra-me ring l, as illustrated more `particularly in Fig. 4;

i crown shaped skeleton web 3 of the upper frame member 2 and is visible through the open ornamental formation of Ysaid web. At its center the lining 9 is formed with a circular orifice for the passage of the shank of the electric light bulb used inconnection with the lamp shade, and in the present construction such orifice is reinforced by a rigid ring or annulus 10 attached to the lining and to the hub portion of the upper frame ring 2 by attaching Ascrews or rivets l1. At its outer margin or border, the lining 9 is folded over the periphery of the upper frame ring 2 and is secured thereto bya winding l2 of thread or the like, such winding being'adapted to force the material of the lining 9 into the above described peripheral groove of the upper frame ring 2 and effect a firm and sulo'st'aii tial Aattachment of parte. l, l

'The main body' tir' j aortion of the lamp Oil shade is formed of pliable material, preferably a plurality of layers 13 of silk or like fabric, arranged to surround the

frame rings

1 and 2 and extending between said rings to constitute the translucent wall of the lamp shade, with the upper and lower margins thereof secured to the respective frame rings l., 2, in manner similar' to that above described in connection with the crown lining 9, that is to sa, the respective margins of each layer 13 of fabric, commencing with the innermost layer as secured in pl ce in the peripheral channels 5 of the

frame rings

1 and 2 by individual windings 14 of thread or the like, with the innermost layer of fabric laying outside the lining 9 and its individual winding 12, and with each succeeding layer of fabric and its individual windings 11i overlaying the preceding layer of fabric, as illustrated more particularly in Figs. 2 and 3. In the preferred method of operation, the last and outermost winding lil of thread will be saturated with a liquid adhesion, either during the winding operation or subsequent thereto, with a view to obtain a binding together of the individual threads of the winding, and thus prevent accidental unwinding of the winding 111 after assemblage and during actual use of the shade.

In my preferred construction shown, the adhesive properties imparted to the aforesaid outer winding 14 is employed to secure in place upper and lower ornamental bands or

braids

15 and 15 applied over the windings 14, so as to cover same and add to the ornamental linish of the lamp shade. In the successive application of the plurality of layers 13 of fabric, any desired pleated or other usual ornamental formation may be imparted to each layer as it is laid in place on the

frame rings

1 and 2 aforesaid.

The central collar or hub i of the upper frame ring 2 is preferably of an ornamental scalloped form as shown, and is provided at one side with a radially arranged attaching screw 16, and in opposed relation to such screw, and within the orifice of the collar, with a pair of inwardly projecting lugs 17. lVith such construction a simple and substantial connection between the lamp shade and the lamp socket of the lamp stand or bracket can be readily made by an engagement of the screws 16 and lugs 17 behind the usual peripheral bead on said lamp socket Having thus fully described my invention, what I claim and desire to secure by Letters Patent is 1 In a lamp shade of the type described, the combination of a frame ring provided with spaced rows of lugs in staggered relation on its periphery to form a holding groove therein, a shade member of pliable material, and a winding of thread for securing a margin of the pliable material in said groove 2. In a lamp shade of the type described, the combination of upper and lower frame rings arranged in spaced relation and formed with holdingl grooves in their outer surfaces, a shade member of pliable material, windings of thread for securing opposite margins of said pliable member iu said holding grooves, and an extensible member arranged intermediate of said rings for effecting a spreading apart of the same and tensioning of the aforesaid pliable member.

3. In a lamp shade of the type described, the combination of upper and lower frame rings arranged in spaced relation and formed with holding grooves in their outer surfaces, a shade member of pliable material, windings of thread for securing opposite margins of said pliable member in said holding grooves, and means for spreading said rings apart, the same comprising a. plurality of intermediate rods, one end of each of which has bearing in a socket in one frame ring, and an adjusting screw arranged in the other of the frame rings and forming an abutmentfor the other end of.

the aforesaid rod.
