INVENTOR. Sal/BEN 1?. Imam/14 MIC W Arm/awn Patented Dec. 25, 1945 UNITED STATES PATENT OFFICE LAIWP SHADE RETAINER Souren R. Kazanjian,'l\lew York, N. Application January 17, 1942, Serial'No. 427,108 3 Claims. (01. 2402-129) This invention relates to lamp shade retainers.

The invention may have application in many different relations. It will be described specificallyinconnectionwith an assembly wherein a lamp shade is tobe retained in association with an ele'ctric-light-bulb-retaining socket. Among themany difierent formsof devices utilized to retain glass or metallic lamp shades in association with different types of bulb-retaining sockets are those which use set-screws to engage shade or socket, as the case may be. The manipulation of these screws may result in breakage of theshade, for instance, wher the flange of a glass shade is engaged by such set-screws. In any case themanipulations necessary to position the usual shades may become awkward.

It is an object of the invention to provide a simple construction by which an adjustable; clamping mechanism provides means for retaining a shade in association with a socket.- In such construction, substantially all the elements of the retaining device maybe housed within'an annular member, such as usually forms a flange for a socket or'shade retaining member. The actuating portions, that is, the portions which are ac-' tually manipulated by a person in setting up the assembly; may b constituted by one or, more small projections.

It is an object of the invention toprovide a. construction for retaining a lamp shade inassociation with a bulb-retaining socket-or similar element, wherein a simple encircling band makes, substantially continuous contact with a portion of shadeor socket, as the case-may be, positivelyto locate and retain the shade in position in relation to the socket.

Other objects of this invention will be set'forth' hereinafter, or will be apparent from the description and the drawings in which are" illustrated embodiments of apparatus exemplifying the in.-.

Fig. 11. is a: view, similar to; Fig. 10, illustrating the position the band. assumes when manipulated to clasp the socket in Fig. l.

In the construction. shown on Figs. 1.. to" 5, inclusive, an ordinary'bulb-retaining socket l0 isshown. A Suchsocket may be supported in any desired. manner. In the structure illustrated, it is suspended from a cable or-similar electrical. conductor'lz, which in turnmay be suspended, iromthe. ceilingor the like.. Socket Hlitself may, if dfesir'ed;, be provided-with,- any'suitable circuit:

making mean '|"4 ,as, for, instance, a switch. The socket "may have the usual recess I6','with means such as the usual threaded contact sleeve I8 for retaining a bulb 28 in position, Socket I8 may be made of any desired material; porcelain or similar material is useful in this connection. In

wall 22 of the socket, and immediately above the bottom opening 24 of recess I6 in which contact I8 is seated, may be a groove 26. Such a groove may be found substantially on all such sockets. Shade 28 is intended to be associated with a member such as socket I8. The shade may be of any suitable construction; it is here shown as of metallic construction; also, it may be of any suitable contouring, as, for instance, substantially conical. At the peak, the cone is cut off to provide an opening 38 at which an annular member or ring 32 is assembled. Ring 32 may be secured to shade 28 at opening 38 in any desired manner. For instance, ring 32 may include a cylindrical strip 34 extending down from an inturned flange 36 of the ring. Strip 34, in turn, may be beaded into opening 38, and into contact with the rounded edge 38 at the inner face 48 of shade 28 at the opening. Bead 42 may then be secured to face 48, as, for instance, by soldering or otherwise, to integrate ring 32 with rounded edge 38.

' Ring 32 may be spun or otherwise formed to provide a substantial recess 44 defined between a wall 46 and a. pair of inturned flanges 36 and 48, respectively, at bottom and top of wall 46. These flanges extend inwardly, and may be turned to define lips 58 and 52. Thus, recess 44 forms means to receive a band 54, the construction 'of which will be discussed further and more fully. Extending across recess 44 and between lips 58 and 52 may be a, plurality of spaced straps 56. These straps serve to retain band 54 against separation from ring 32, and also serve to impart a,

definite arcuate contour to band 54.

It will be noted from Figs, 2, 4, and 11, that band 54, which may be made of spring metal bent into the arcuate form shown, extends more than 368, and, in fact, extends almost 720. Substantially the entire band is housed within the extent of recess 44. The band is narrow in its vertical extent Band 54 is reduced in its transverse extent to form a slip section 58. At section 68, an elongated slot 62 is formed in band 54, and is of sufficient width so that slip section 58 may move therethrough.

One end 64 of band 54 may be anchored to ring 32 in any desired manner, as, for instance, by being riveted or soldered thereto. For the other end 66 of the band a handle or manipulating member 68 may be provided. To retain the handle in position a suitable construction may include an opening 18 formed through band 54 and receiving an end 12 of handle 68. This end 12 may be headed over to lock end 66 with relation to handle 68.

.In addition to headed over end 12, handle 68 may have a short stem 14 of such dimensions that it may extend through a slot 16 in wall 46. Beyond stem 14, handle 68 has an enlarged grip 18 to be grasped by ones fingers.- An ear 88 may be afiixed to the outside face of wall 46. The extent of slot 16 is such that handle 68 may be brought to an end 82 of the slot, adjacent to which ear 88 may be located. Ear 88 may be a handle similar to handle 68, and, in the same manner as handle 68, may be secured to end 64, and extend through slot 16. Thus, it would be possible to bring both handle 68 and ear 88 into associationwith each other, To prevent rotation of Shade 28 with relation to socket I8 during such manipulation, the form shown on the drawings, in which end 64 is anchored directly to wall 46 at its inner face, has been found desirable,

As handle 88 is manipulated to approach ear 88, ends 64 and 66 of the band 54 approach each other, and consequently reduce the area encompassed by the inner faces of the band. This is made even more effective where straps 56 control band 54. If socket I8 be positioned so that its groove '26 is in immediate proximity to band 54, the band, on such movement of handle 88 towards ear 88, will become seated in groove 26, and lock shade 28 and socket I8 together.

In order to retain the members in this associated relationship, car 88 may be locked in fixed relation to handle 68 by any suitable means. For instance, car 88 may have an opening 84 which may include a substantially spherical recess 86. Recess 89 may form a bearing for a ball-shaped bearing portion 88 provided upon a stem 98 of a screw 92. Recess 86 and portion 88 cooperate to retain screw 92 against longitudinal movement, and yet permit limited rotation of the stem about its longitudinal axis and also limited swinging movement of the stem into a number of different positions, portion 88 then acting as a hearing.

Grip 18 may have a socket 93 in which is seated. a ball member 95 having a screw-threaded passage 94 formed therethrough. The threaded portions of screw 92, when stem is properly swung into position, after grip 18 has been brought adjacent to ear 88, may be engaged in passage 94. Then, by turning manipulating head 98 of screw 92, handle 68 may be cammed into closer relation to ear 88, and the gripping action of band 54 in groove 26 may be increased. Thus, socket and shade may be fixedly anchored to each other, or, by unthreading screw 92 from passage 54, handle 68 may be moved away from ear 88, and the shade then separated from the socket. When handle 68 and ear 88 are thus separated, screw 92 will still be retained against loss by reason of the cooperation of portion 88 with recess 88, and will remain in position for immediate engagement in passage 94 when grip 18 is approached properly to ear 88.

In Figs. 6 to 9, inclusive, a modified construction is shown in which a shade I88 is carried from a ring I82, where ring I82 may have a threaded flange I84 to be engaged upon the complementary threaded portions I86 of a metallic electric light socket I88 of usual construction. The purpose of such construction is to suspend a glass or similar shade with relation to socket I88. In this case, ring I82 has a wall II8 which connects flange I84 to an annular wall I I2. Wall II2, like ring 32, is, by means of a flange H4 and turnedin prongs I I6, formed so as to provide a recess I I8 for receiving a band I28.

Band I28, like band 54. may have a reduced portion I22 for passage through a slot I24 formed in band I28. One end I28 of the band may be anchored to wall H2. The other end I38 of the band may be passed through an angularly and tangentially cut slot I32 formed in wall I I2 so as to appear at the outer face I34 of wall I I2. At this outer face, a guard I36,-shaped to conform to the contouring of wall I I2, may be secured to end I38. This guard is formed by an arcuate plate having bent back flanges I31 at its edges for engagement over the edges of an arcuate plate I39 which is secured on outer face I34.

.Thus V guardjl36 i permitted limited movement, and

serves as a stop to prevent the retraction of end I30 into the interior of recess H8. Guard I36 also prevents moisture from passing through slot I32 into the interior of the device.

A projection I38 may be formed on wall H2. This projection may have an opening I45. In a manner similar to screw 92, a screw I42 may be assembled on projection I38 by means of a balland-socket connection. An ear I44 may be affixed to or form a part of guard I36, and may have a ball-and-socket-supported threaded member I45 to permit facility in bringing screw I42 into engagement with a threaded opening I41 in member I45.

Glass shade I may have an opening M8 having a flange I50. A grOOVe I52 may be provided in flange I50 for engagement by band I20. Band I20, on manipulation of ear I 44, will be contracted into groove I52 in the manner hereinbefore described. If it is desired, members similar to straps 56 may be provided. However, the engagement of the band through tangential slot I32 has been found sufiicient to retain the band in arouate formation.

As ear I44 approaches projection I38, or as handle 68 approaches ear 80, the angular extent of the band increases while the effective area of the respective openings are decreased, yet the effective length of the bands remains the same. Also it is to be noted that there is no point con tact between the band and the shade or the socket, as the case may be, so that the flat contacting surfaces of band and groove result in transmission of force in such manner that no direct breaking stress is produced either in socket or in shade.

Many other changes could be effected in the particular apparatus designed, and in the methods of operation and use set forth, and in specific details thereof, without substantially departing from the invention intended to be defined in the claims, the specific description being merely of exemplifying embodiments in accordance with the statutes.

What is claimed as new and useful is:

1. Means for supporting a lamp shade in position in relation to an electric-light-bulb-retaining socket, the means including an annular member, the annular member carrying a flexible band of material and positioning the band between the socket and the shade, the ends of the band extending past each other to form a complete loop within the annular member, immediately juxtaposed portions of the looped band being interlocked so that they cannot move apart but can move relatively to each other, and means for moving the ends of the band relatively to each other to adjust the efiective area encompassed by the looped band.

2. Means for supporting a lamp shade in position in relation to an electric-light-bulb-retaining socket, the means including an annular member, a flexible band of material housed within the annular member, the annular member positioning the band between the socket and the shade, the ends of the band extending past each other to form a complete loop within the annular member, immediately juxtaposed portions of the looped band being interlocked so that they cannot move apart but can move relatively to each other, and means for moving the ends of the band relatively to each other to adjust the effective area encompassed by the looped band.

3. Means for supporting a lamp shade in position in relation to an electric-light-bulb-retainlng socket, the means including an annular member, the annular member carrying a flexible band of material and positioning the band between the socket and the shade, a portion of the band being formed with an opening, another portion of the band being formed with a reduced portion, the reduced portion and the opening cooperating so that the ends of the band extend past each other to form a complete loop within the annular member, and means for moving the ends of the band relatively to each other to adjust the efiective area encompassed by the looped band.
