LAMP SHADE AND THE LIKE.

Application filed September 1, 1925, Serial No. 53,794, and in Great Britain January 21,1925. Renewed February 13, 1929,

This invention relates to lampshadesend the like of the kind in which a covering of textile fabric, paper, parchment or the like I is mounted on a framework of a convenient form.

The framework for lampshades of this kind usually comprises a rigid structure generally formed of a series of lengthsof wire bent to suitable form and soldered together,

andif such framework is'to be covered with acter of the decorationof the rooms in which they are used or the dismantling of such shades to effect the cleaning oft-he covering material thereof is'very' rarely effected; One of the objects of the present inven tion is to provide afcollapsible framework from which the covering maybereadily' de tached' and to which it maybe readily applied.

A further object of the invention is to pro vide a framework which may be adjust-able in size.

A fiirther object: of the invention is to provide a fi'ameivorkof'whichthe various parts thereof may be adjusted to vary the shape of the framework. I I

In order that the invention may beclear' ly understood reference is made to the accompanying drawings which illustrate j by Wayne examplevari-ous embodiments of my invention and in which Fig. 1 1s a perspective view of a lampshade HCCOIClll'lgtO a'preferred form of my invention the covering beingshown removed from'the greater part of the framework so as to clear-1v show the construction thereof.

F1gfl8 is a diagrammatic view illustrating attachment of a lampshade to a are "connected to thefabrie car i a compound shape of shade which can be made according to my invention;

Referring to Fig. l of the drawings the simple form of framework illustrated therein comprises two collapsible members 1 and2, of ring like formation, i. e. circular,elliptical, or other closed shape, which are spaced 7 apart by means of'a plurality of stay meme bers 3,wh'ich, for the small size of lampshade as illustrated, are three innumber but which,

for larger'lampshades may be fouror more. j The stay members are not rigidly attached to the rings 1 and 2 but are merely indetach able engagement therewith and such rings are held in engagement withsuch stay members,

by means of the material 4, whichis connect ed at its opposite sides respectively to thesaid rings 1 and 2. The material 4 which may be of silk or other textile material or of paper or the'lik is suitably shaped according to the form of shade which it is intended to cover; If thelampshade is cylindrical thenthe mate rial will comprise a straight length'of mate rial with its upper and lower sides of a length corresponding to the circumference of the shade. If the lamp shade is the shape of a frustum of a core as illustrated in Fig. 1, then the material will preferably be of sector shape with its upper and lower sides of lengths corresponding to the circumferences of the upper and lower- rings 1 and 2 respectively; though such a shape is not essential since if desired the material may be of the same shape as for a cylindrical shade in which case it would bepleated to a greater extent about the upper ring 1 than about the lower ring 2. The collapsible rings 1 and 2 are divided'or split transversely, their ends being adapted to be connected together in any suitable manner, andthe opposite sides of the material a are so formed that they maybe attached to the split rings, If the material when mounted upon the frame is intended to be pleatedthe material at'each side thereof may be provided with a series of holes by which it may be threaded onto the rings, one hole being provided in each side of each pleat. Preferably however each side of the material is provided with a fairly broad hem through which the split rings 1' and 2 are threaded. The material is of such a length that when fixed onthe frame, the opposite ends thereof contact, thus forming a com plete covering for the frame.

The stays 3 are preferably of resilient materialand adapted when engaging the rings 1 and 2 to press them" apart thereby stretch: ing the material 4 attached thereto and insuring secure engagement between the stays and rings.

, The preferred form of stay is illustrated in greater detail in Figs. 2 andVSof the drawings, and comprises two pieces of resilientv strip metal 6 and 7 bound together at their central portions byrivets or by a metallic sleeve or the like 8 encircling the same. The ends 9 of said members 8 are preferably bent inwardly a slight amount so that they will engage the rings 1 and 2 at a greatangle and .such ends are each provided with a recess 10 which recesses are adapted to receive the rings when the stays are placed in engaging position therewith; The ends 9 engage the rings 1 and 2 through the material a when the rings are enclosed in thehems formed on the sides of the material and to prevent any damaging of such material such ends are preferably tapered slightly and the corners of same are rounded off as shown in Fig. 3 of the drawings. If desiredsuch ends may be provided with protecting clips of thin metal such as brass. When applying the stays to the rings 1 and 2 the pairs of legs on the opposite sides of the central binding member 8 are opened out when the ends can be readily engaged with the two rings 1 and 2. The modified form of stay i Figs. 1 and 5 of thedrawings is adjustable in length and'is also pre furably made of resilllustrated in ient metal. Any means may be adopted for making the stay adjustable but in the construction illustrated the stay is made in two parts the shank pieces 11, 12 being in sliding engagement with each other and held in such engagement by means of tongues 13 provided in the ends of such shank pieces and embracing the opposed shank pieces respectively. To facilitate engagement and disengagement of such parts recesses 14 are provided in the shank pieces adjacent the tongues 13, such recesses being of a size which will allow of the passage therethrough of the overlapping portions of the tongues when the stay is ex tended to its limit with the tongues on the op posed shanks adjacent each other. To prevent slipping between the two opposed shanks a screw 15 is provided in screw threaded engagement with one of the shanks and adapted to engage the face of the other shank when operated, though any other wellknown means may be adopted for this purpose.

The outer ends of the shanks are preferably bifurcated and the ends of such bifurcated portions are soshaped that they are adapted to readily engage the inner edges of the two rings 1 and 2. The shape of such endsma y beas illustrated in Fig. 5 of thedrawings, the metal of the stay being bent to form a recess 16 which is adapted to receive the ring, such recess being defined by a forward upwardly extending portion 17 and a rearward upwardly extending portion 18. The upwardly extending portions 18 are preferably'bent forward attheir upper ends so as to tend to retain the fabric carrying ring in the recess 16 and the metal strip is preferably returned upon itself to provide a rounded front edge which will not damage the material. The space between the member 17 and the forwardly extending portion 18 must of course be sufficient to allow of the insertion of the material arryin'g ring with the material thereon.

In order to facilitate the insertion of the material carrying rings in the recesses 16 and be pivotally mounted on the stay as clearly shown in Figs. 6 and 7 of the drawings. In

such a construction the material of the stay is bent to form the forward upwardly extending portion 17 and returned upon itself forming the shoulder '19. The end portion at a distance below such shoulder is divided so as to form two spaced portions 20 which are bent about an axis to form bearings for two side projections 21 on the member 22 which defines the rear side of the recess 16. The member 22 is held in its upright position by a spring 23 fixed at its lower end to the body portion of the stay as by rivets and engaging at its upper portion against a flat portion on the member 22. A hole 25 is provided in the member 22 adjacent the upper the binding members 8 of the stays 3. The

en d of the spring 23 to allow of such member being turned rearwardly about its pivots when assemblingor dismantling the shade.

The rings 1 and 2 may be made of strip metal or of wire. In Figs. '8 and 9 a ring has been illustrated composed of strip metal. Such ring is adjustable in size and is adapted to be readily broken and reformed. For this purpose each end of the ring on the sides thereof is provided with two tongues 26 adapted to embrace the material of the ring to the rear of the other end thereof. In order to break or assemble the ringyrecesses 27' are provided in the side edges of the ring adjacent the tongues 26 such recesses being of a depth corresponding to the amount by which the tongues 26 overlap the edges of the ring in engaging same. The outer corners of the overlapping tongues 26 are preferably rounded off as shown in Figs. 8 and 9 so as to allow freedom of movement of the end'of the ring within the hem on the covering material 4. t

In Figs. 10 and 11 a ring composed of me tallic wire is illustrated such ring having fixed at one of its ends as by soldering or welding, a sleeve 28 which provides a passage adjacent the end to which it is fixed through which the other end of the wire ring may be I they will offer as little interference as possible to the assembling of the fabric thereon.

Any suitable means may be provided for connecting the shade to the lamp or to its support. Fig. 12 illustrates means specially adapted to be used in connection with they construction of shade illustrated in Fig. 1 of the drawings. Such means comprises three members 30 preferably made of wire which are adjustable in length each of which is shaped at one end into an annular member 31 adapted to cooperate with the lamp support and at the other end into an upstanding pin like member 32 adapted to engage within a socket 32 provided for instance in each of adjustability of the members 30 is effected by making them in two parts. Each ofsuch parts comprises a stem 33 and such parts are connected respectively at their outer'endsyto the members 31 and 32 and are held in slid:

ing engagement relatively to each other by the inner endsthereof .bemg bent over as at 34 so as to encircle the adjacent stem. The

stem portions 33 of the members 30 are preferably inclined relatively to the plane of the end portions 31, the direction of inclination depending upon" whether the shade isto be sp'ectively'of the members and arms, which engage the opposed body portions of such members. The outer ends of said members 37' are providedrwith claw like members 39 preferably of circular cross section and such claw likemembers are adapted to embrace the upright portionsof the stays 11. In on der to readily attach'such arms to the said stays recesses 40 (as clearly shownin Fig. l)

are provided in opposite sides of said upright portion thereof of a depth to allow ofthe open ends of such claw like members passing therethrough. Ata shortdistance fr0msaid recesses and at oppositesides thereof shoulders ll and 42 are provided which are adapted to limit the sliding movement of the stay within the clawlikemembers and to rest against such members and thereby support the "shade thereon. The shoulders 41' are provided so that the shade may be used with :1. depending lamp, bulb and the shoulders 42 are providedso that the shade may be used with an upright bulb in which'case the end of the stay member provided with the mem bers 41 and42 willbe in engagement with the lower ring. The claw like members enclose a space which is. somewhat broader than the.

thickness of the stays and owing to such members being of circular cross section they can readily engage the stay members whether they are vertical or inclined.

A further modified form of supporting member is illustrated in Figs. 15 and 16 of the drawings, In this form the outer ends of the arms. are provided with. a hook shaped end 45 adaptedto engage under one of the rings of the shade. The length of such arm may be made adjustable as by making it in two parts 46, 47, one of which isadapted to slide within. the other. The inner ends of such. arms 40 comprise ring shaped members 48. Thearms maybe inclined relatively to the plane of the ring shaped members or not as is desired;

If desired the ring shaped 'members, on

the supporting means -illustrated in Figs; 12-16'may'be dispensedwith and depending pin likemembers' c'onnected'to vthe inner end of each. of the radially extendingarms may be substituted thereforjtin' which case a mem ber, such as that illustrated in; Fig. 1'7,' containing a plurality of sockets 4.9, for the re for attaching to the coveringmaterial of theshade, which are of an adjustable nature and which are split transversely these features of such members are not essential since such members may be in the form ofembroidery ring that is they may comprise two rings one fitting within the other in frictional engagement with each other. With rings of this kind the opposite sides of the material the engaging ends of such stay memberswould be slightly modified to more effectively engage with such double rings, for instance such endscould be made so as to it snugly around the inner edge of each of the double rings the material being clamped between the double rings so as to extend over the outer edge of the outer rings thereby fully covering such rings. In such a construction there would be no possibility of damage being caused to the material by the stay members since they would engage the clamping rings directly.

It will beappreciated from the description hereinbefore contained that the shade may be readily attached to and detached from the lamp support and that it may be readily dis.

assembled and the parts thereof broken down so asto allow of the readydetachmentof the covering. 7

Further, in most of the constructions de scribed the parts thereof including the means for attachment to the lamp shade are adjustable in size so that when the shade has been dismantled they may be adjusted and assembled again to form a shade of different size or shape. The stays illustrated in Figs.

.13 of the drawings are not actually adjustable in size though their resiliency is such that they will allow of a considerable variation in the width of the material used in covering the shade. I v I By altering the size of one ring to a greater extent than the other the frame may be changedfrom a cylindrical shape to that of a frustum of a cone or vice versa, or the slope of the sides thereof may be altered. Further three rings could be combined and spaced apart by two series of stay members to form a frame of the shape illustrated in Fig. 18 of the drawings, and the slopes of the sides thereofmay be altered as desiredby adjusting the sizes of the three rings.

If desired the stay members may be covered with material as by wrapping them with tape such material being of a color which harmonizes with that of the material of the shade.

If the frame it to be used with a covering of stiff material such as cardboard or the like the rings 1 and 2 may be channel shaped so as to engage about the opposite sides of the material and such rings could be held together by stay members of the kind illustrated in Figs. 4; and 5 of the drawings but having their ends in the form of hooks or the like adapted to engage over the outersides of such rings.

Numerous modificationscould be devised in embodying .my invention in practical structures, and I donotwish to be limited to the constructions illustrated or described in this specification but desire to cover all embodiments coming within the scope of my appended claims.
