' SHADE HOLDER.

Application filed January 9, 1926. Serial No. 80,155.

T 0 all whom it may concern:

Be it known that I, JOHN F. ZISKA, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shade Holders, of which the following is a full, clear, and exact description,

The invention relates to shade-holders It is now common practice to secure lamp shades, the frames of which are usualy provided with a central ring, to a supporting column, by means of a screw-socket or nut which is threaded to a protruding portion of the column. lVhere it is desired to have a surmounting ornament, it is usually carried by the nut or socket. In the use of these devices, it is necessary to unscrew the socket.

tion between the shade and the support which" permits the shade to be removed andreplaced without removing the retaining device for the shade. By providing such a connection, the necessity of screwing the retaining device, such as the socket or nut on the support, and unscrewing it therefrom every time a replacement or removal of the shade is to be effected, will be avoided.

The invention consists in the several novel features hereinafter set forth and more par ticularly defined by claims at the conclusion hereof. y

In the drawings: Fig. 1 is a perspective of a device embodying the invention. Fig. 2 is a vertical section, parts being shown in elevation. Fig. 3 is a section taken on line 3-3 of Fig. 2. I

The invention is exemplified in connection with the usual supporting tube 5, to which electric light sockets 6 are usually secured, and a 1amp-shade14, the frame of which comprises radial wires 13 which have their inner ends fixedly secured in a central ring 12. The parts thus far described may be of any suitable construction, as well understood in the art.

the device or the ornament.

' The improved retaining device or holder comprises a member 8, the lower end of which is screw-threaded to the supporting tube 5, 'so'thatit will be fixedly sustained thereby. Member 8 comprises alower circular portion 10-, into which is pressed, or otherwise fixedly secured, a bushing 11, in

' which the thread is formed for connecting the member 8 to the tube 5. Member 8 is provided with a horizontally extending slot 9 which is adapted to receive, by lateral movement,the ring 1.2 of, the shade frame. The slot 9 is open around its-side, except where the bottom portion 10 is joined to the upper portion of the member 8, as at 10 Byreason of this slot formation,'it is possible to in'sertthe ring 12 onto, and to withdraw it from, the portion 10 of the retaining member. 8 by lateral movement of the shade.

The space between the wires 13 is usually sufficient topermit the shade to be lowered over the upper portion of the retaining member and the ornament usually carried thereby, as well as to permit the shade to be lifted off the retaining device, without removing In order to more firmly secure the shade in the slot 9 and on the portion 10 of the retaining member 8, a spring-pressed stud 16 is slidably mounted in a vertical socket 8 in that portion ofthe member 8 whichis disposed above the slot 9. This stud is provided at its lower end with a downwardly facing enlarged convex head 17 which is adapted to partially enter the opening 15 in the riug12 of the shade frame. A spring 18 is confined in socket 8 and is applied'to the stud 16 to press the stud downwardly so its head-l7 will firmly hold the shade frame against vertical or lateral movement. cross pin 19, fixed. in thestud 16, is extended into a slot 20 which limits the downward movement of the stud 16 by the spring, sothat in its lowermost position the ring 12 may he slipped under the head by lateral movement of the ring. When it i is desired to remove the shade, the ring 12 can be forced laterally to lift the head 17- until the ring has collared the head and has been withdrawn from the slot Anornament 21 is usually mounted on top of the retaining member 8 and, if de sired, this ornament may be connected to said member by a screw-thread 22, to permit the same member to be used with different ornaments.

The purpose in using a bushing 11 isto permit the stud 16 with its head 17 to be initially inserted into operative position from the bottom of the member. After the stud has been placed in position, the bushing 11 is fixedly pressed or otherwise permanently secured in the member 8.

The invention exemplifies a retaining device or holder for a lamp shade which dispenses with the necessity of manipulating a socket or nut when an interchange, placement or removal of the shade is to be effected, because, in the placement of the shade, it is'only necessary to lower the shade around the retaining device and shift it laterally into the open sided slot 9 and into position to be secured by the spring-pressed retaining stud, and to remove the shade, it is only necessary to move the shade laterally to disengage the ring 12 from the retaining device and then lift the shaderirom said device. The invention further QXOD-If 'EllllQS a retaining device for lamp-shades, in which the manipulation of the shade alone is necessary in its placement and removal.

' The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended elaims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

1. A shade-holder comprising a retaining member provided with means whereby it may be secured to a support and with an open sided slotto permit lateral placement of the ring of a shade-frame into the member and its withdrawal therefrom, and means for holding the ring in the member.

2. A shade-holder comprising a retaining member provided with a screw-thread whereby it may be secured to a supporting standard and with an open-sided slot to per mit lateral placement of the ring of a shadeframe into the member and its withdrawal therefrom, and means for holding the ring in the member.

3. A shade-holder comprising a retaining member provided with means whereby it may be secured to a support and with an open sided slot to permit lateral placement of the ring of a shade-frame into the memberand its withdrawal therefrom, and means in the member and above the slot for holding the ring on the lower face of the slot.

4. A shade-holder comprising a retaining member provided with means whereby it may be secured to a support and with an open sided slot to permit lateral placement of the ring of a shade-frame into the member and its withdrawal therefrom, and yielding means movable by the ring, for securing it in the slot.

5. A shade-holder comprising a retaining member provided with means whereby it may be secured to a supportand with an open sided slot to permit lateral placement of the ring of a shade-frame into the member and its withdrawal therefrom, and yielding means in the slot and movable by the manipulation of the ring, for securing it in the slot.

6. A shade-holder comprising a retaining member provided in its lower portion with a screw-thread for connection to a supporting standard, and with an open sided slot to permit lateral placement of the ring of a shade-frame into the slot and its removal therefrom, and a stud in the upper portion of the member forholding the ring on the lower face of the slot.

'1'. A shade-holder comprising a retaining member provided in its lower portion with a screw-thread for connection to asupporting standard, and with an open sided slot to permit lateral placement of the ring of a shade-frame into the member and its removal therefrom, and a spring pressed stud in the upper portion of the member for clamping the ring on the lower portion of the member.

8. A shade-roller comprising a retaining member provided in its lower portion with means for connection to asupporting standard, and with an open sided slot to permit lateral placement of the ring of a shadeframe into the member and its removal therefrom, and a spring-pressed stud in the upper portion of the member, provided with a head movable by the ring for clamping the ring to the member.
