Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed May 12, 1909. SeriaI No. 495,415.

7 To all whom it may concern:

Be it known that I, WILLIAM S. STAPLEY, of the city of Bridgeport, county of Fairfield, State of Connecticut, have invented new and useful Improvements in Shade- Holders, of which the following is a full, clear, and exact description, when taken in connection with the accompanying draw-: ings, which form a part thereof. I

This invention relates to holders for shades, such asshades of incandescent lamp fixtures. In such case, the shade holder is to be attached, securely to the socket in such a way that it will not become loosened by jarring, and in addition the glass or metal shade is tobe supported by the holder in an effective manner.

The use of heavy glass shades requires considerable strength in the holder, and the object of the present invention is to provide a holder which shall be efiicient, and at the same time simple in operation and inexpen-j sive in construct-ion. I

To these and other ends, the invention consists of the several improvements and combinations of parts set forth and claimed hereinafter. I

Figure 1 represents a side elevation of shade holder secured to a socket and sup-, porting a shade, Fig. 2, a vertical section} through the holder, Figs. 3 and at, horizontal sections on lines 3-3 of Fig. 2, the ring or collar being shown in dilferent positions, Fig. 5, a horizontal section on line 5-5 of Fig. 2, Figs. 6 and 7, vertical sections: through the catch or locking device, the catch being shown in different positions, Fig. 8, a perspective View of the holder or shell by itself, Fig. 9, a perspective view of the ring or collar by itself, and Fig. 10, a detail perspective view of the wire catch or locking device.

In all figures, similar letters of reference represent like parts. 1

Referring to the drawings, the part designated by the letter A represents the socket of an incandescent light, and B the shade of glass or othersuitable material.

C designates the hollow holder or shell formed of sheet metal somewhat tapered so that the opening at the upper end for the reception of the socket A is smaller than that at the lower end for the shade B. In the upper end are formed a number of vertical slots D so that the strips or plates E inturned edge of a ring or collar K loosely mounted on the upper end of the shell O to prevent the collar from being drawn off the shell. The upper end of the collar K is turned inward over the outturned edges F of the flexible strips E so as to prevent the parts from rattling.

Between the groove G and the upper edges F each of the flexible strips E is provided with an inwardly projecting cam face L. This cam face L, as shown more particu-. larly in Fig. 3, is gradually inclined outward until it reaches about the central line of the strip when it is curvedsharply inward, thereby forming a shoulder M. On the ring or collar K are formed a number of correspondingly spaced inwardly projecting shoulders N which are adapted normally to lie in the slots D between the flexible strips E (Fig. 4). WVhen the shoulders N are in this position, the strips E maybe forced outward to allow the insertion or removal of the socket A. If the ring K is turned on the holder C, the shoulders N will travel on the outer face of the cams L forcing the flexible strips E inward so that they will grip the socket Afand bind the bead H of the socket within the groove G. As the shoulders N of the ring K come in contact with the shoulders M of the flexible strips E further rotation ofthe ring is prevented in the direction indicated by the arrow (Fig. 3). v

When it is desired to unlock the socket A the ring K is turned in the opposite direction from that indicated by the arrow (Fig. 3), and when the shoulders N come into position opposite the slots'D between the'flexible strips E (Fig. 4) the flexible strips may be pushed outward by the bead of the socket A as it is removed. To aid in turning the ring or collar K serrated or knurled beads W are formed thereon.

Near the lower edge of the holder C are two indentations 0 so formed as to engage the annular flange P on the upper edge of catch consists of a wire, the ends R of which lie along the outside of the shell or holder C (Fig. At its center, the wire is doubled on itself to form a handle T, and on either side projects inwardly to form two shoulders S, slightly separated, so as to permit of a certain flexibility or spring in their movement. The central portion or handle T of the catch projects outside of the holder C (Figs. 1 and 8). The ends R of the wire are held in position by means of a plate V riveted or otherwise secured to the outer face of the shade holder, as shown more particularly in Figs. 1 and 8.

The operation of securing the shade to the holder is as follows: The shade is put in position at the lower end so that its flange P will fit over the indentations 0. By means of its handle T the catch is turned on its pivot formed by the ends B so that the inwardly projecting shoulders S will engage the flange P of the shade, thereby supporting the shade with the indentations 0. To remove the shade, it is merely necessary to turn the handle T of the catch down to the position shown in Fig. 7 when the shade may be freed from the indentations 0.

Having now described my invention, what I claim and desire to secure by Letters Patent, is

1. The combination with a lamp socket; of a shade holder; having a plurality of clamping plates formed integral therewith and separated by slots; a. ring or collar mounted on said plates and having inward projections adapted when in said slots to permit the expansion of said plates, substantially as described.

2. The combination with a lamp socket member; of a shade holder member having a plurality of integrally formed separated spring clamping plates extending substantially parallel to the surface of the socket and operable to closely surround th same; a locking shoulder carried by one of said members for locking them together; each of said plates having a surface portion above said shoulder inclined to the curve of the socket, and means operable to move on said plates to contract the same and force said Copies of this patent may be obtained for surfaces against the socket member, substantially as described.

3. The combination with a lamp socket member; of a shade holder member having spring plates extending substantially parallel to the surface of the socket and operable to closely embrace the same, said plates being separated by slots; a locking shoulder carried by one of said members to lock the two together; a clamping member having inclined portions bearing against said plates above said shoulder and releasable from said holder member through said slots, substantially as described.

4. The combination with a shade; of a holder; a locking clamp consisting of a wire pivotally secured to the holder and doubled on itself to form an engaging shoulder adapted to swing on a pivot transversely to the axis of the holder, substantially as described.

5. Thecombination with a shade; of a holder; a locking clamp consisting of a wire, a portion of which forms a horizontal pintle and another portion of which is doubled on itself to form a plurality of engaging shoulders adapted to swing in a vertical plane, substantially as described.

6. The combination with a shade; of a holder; of a locking clamp consisting of a wire having a plurality of engaging shoulders adapted to project within the holder and capable of a slight lateral movement therein, substantially as described.

7. The combination with a shade; of a holder; a locking clamp consisting of a wire having its ends form a pivot and portions engaging shoulders within the holder; and a plate secured to said holder holding said ends in place, substantially as described.

8. The combinationwith a shade; of a holder having a plurality of indentations adapted to engage a recess or recesses in said shade; and a locking clamp pivoted on said holder engaging said shade to hold it in engagement with said indentations, sub stantially as described.

In witness whereof, I have hereunto set my hand on the 24th day of April, 1909.
