SHADE-HOLDER.
. Specification of Letters Patent.
PatentedMarch 16, 1909.
Application filed September 14, 1908. Serial No. 452,979.
To all whom it 'may concern:
Be it known that I, WILLIAM S. STAPLEY, a citizen ofthe United States, residing ating the shade against the possibility of deandv to expand and in which the locking of the shade to'-the holder and of the holder tola lamp socket shall be effected by threaded collars which turndownward to look so thatit is impossible for them to become loosened I by vibration.
W'ith these and other objects in view I have devisedthe novel shade holder of which the following description in connection with the accompanying drawing is a specification, reference characters b cate the several parts:
Figure 1.is an elevation partly in section,
illustrating the construction of my novel shade holder'and its mode of operation in secuning a shade to a lamp socket; and Fig. 2 is a detail view partl in elevation and partly in section with the older-locking collar detached. My novel shade holder com )rises simply a body, two locking sleeves and a plurality of pivoted spring chps all of which are formed -f1lom sheet metal and a retaining ring for the c 1 s. v 40. l0 denotes the body as a whole. At the lower end of the bod is a flange 1.1 formed i by curving the meta outward and then inward, against which the engaging flange of the shade rests; above flange 11 is a circumferential groove 12; above the groove a rolled thread 13; abovethread 13 a flange 14 which i's'formed after assembling, as will be more fully explained; above flange 14 a i rolled'thread 15"of less diameter than thread 13, and above thread 15 a plurality of spring jarms 16, said spring arms being provided ,with an internal groove 17 and at their upper endswith an inwardly inclined lip 18; that is to say, the spring arms comprise sections of ordinary variations in the attaching flanges of shades, which while holdtachmentwill, permit the shade to rotate ing used to indibeen placed over the body.
breaking the shade.
the internal groove and theinwardly inclined lip. j r
19 denotes the holder-retaining sleeve which is provided with a thread 20 adapted to engage thread 15 on the body and with an inwardly-inclined flange 21' which corresponds with-and engages the sections of lip 18 on the body.
22 denotes a lamp socket provided near its lower end with the usual external rib 23. I
24 denotes a shade provided at its upper end with the usual fetaining flange 25. The flange of the shade is engaged by a plurality of spring clips 26 which are pivoted on the body and swing'in the vertical plane. The. clips are shown as made from strips of sheet metal and provided at their lower ends with rolls27 which pass under the flange of the shade and at their upper ends with eyes 28 throu 11 which retalning ring 29 passes. This ring fits closely in groove 12 in the body which is shown as provided with recesses 30 to receive the eyes.
31 denotes the shade retaining sleeve whichis provided with a thread 32 adapted to engage thread 13 on the body and with an outwardly inclined flan 'e 33 which is adapted to engage the outer laces of the clips and retain them inengagement with the shade.
In the present instance, flange 33 retains the rolls of the clips under the flange ofthe shade.
The shade retaining sleeve is retained in position on the body by. upsetting flange 14 on the body outward after the sleeve has The operation is as followsvln attaching a shade to a holder, the shade retaining sleeve is turned upward as in Fig. 2, then the retaining flange 01' the shade is placed in engagevertical plane, the holder is thereby made selfeadjusting to the ordinary variationsin the attaching flan es of different styles of shades and the resi iency of the metal of the clips and the rolls at their lower ends permits theshade to be rotated if required without detachment and provides for any possible amount of expansion -without danger 1 of As the locking operation of the sleeve is downwa d, it follows that lamp socket, as in Fig. 2, and then the s ring rib 23 on the lamp socket, as clearly shown '20 connection with Fig. 1. The holder-retainthese'ctions of the lip on the spring arms and no amount of vibration can possibly loosen the sleeve and release the shade, the effect, if any, of'vibration being to cause the sleeve to press downward u on the clips. The attachment of the hol er to'a lam socket will be readily understood from 1g. '2-in mg sleeve is placed over the lower end of the arms are pressed into engagement wit the lower end of the socket, the rib of the socket. passing into the groove 17 in the spring arms. The sleeve is then turned downwai d into engagement with thread 15 on the body. This causes flange 21 on the sleeve to engage press them inward closing the wall of the groove 17 in the spring arms tightly upon in Fig. 1, thus locking the holder to the lamp socket against the possibility of removal without turning the sleeve backward, it being obvious that as the locking movement. of the sleeveis downward,'vibrationcannot loosen theholder butif it has any effect will cause the sleeve to move downward and lock the holder still more tightly to the socket.
Having thus described my invention I claim;
1. A shade holder comprising a body having a flange forminga bearing for the shade to rest against and havin rolled threads of different diameters, sha e -'engaging clips pivotally connected to the body adjacent said flange, spring arms'at the upper end of with said. threads to lock the respective engagingineans to a lamp socket and a shade when said sleeves are screwed toward the lower end of said body.
3. A shade holder comprising a body having at its lower end a flange against which a shade tests and having "above said flange a groove, a in said groove, clips pivoted on said ring andadapted to engage a shade, and
a" threaded sleeve engaging the body and the clips in' the lockingacting to retain posit1on; I v
