UNITED STATES PATENT OFFICE.
AUGUST MOTSCHENBACHER, OF BROOKLYN, NEW YORK, ASSIGNOR TO L. FLAU'T 8:; 00., OF NEW YORK, N. Y., A CORPORATION 01 NEW YORK.
SHADE-HOLDING ATTACHMENT.
Specification of Letters Patent.
Patented Feb. 28, 1922.
Application filed October 5, 1920. Serial No. 414,813.
siding at Brooklyn, in the county 01' Queens and State of New York, have invented a certain new and useful improvement in Shade-Holding Attachments, 01' which the 'it'ollowing a specification.
My invention relates to the lighting ii:- ture art, and has for its object to provide means for firmly and securely retaining a shade within the shade holder, which will at the same time be adjustable so as to be adapted for use with varying sized shades.
A further object is to provide such an attachment in a simple, durable and inexpensive construction and which may be easily and quickly operated to insert or remove a shade.
My invention consists of certain details of eoi'istructioi'i hereinafter set forth, pointed out in myclaim and illustrated in the accompanying drawing in whiehl ig. 1 is a side elevation showing my improved device.
F 2 is a bottom plan view of the same.
Similar reference numerals refer to sim ilar parts throughout the entire description.
As shown in the drawings, 10 is used to indicate a shade holder of the ordinary bellshaped type, having a plurality of slots 11 in its depending flange, and near the base thereof. The numeral 12 indicates a spring wire, circular in conii'o'rmation and of lesser diameter than the inner diameter oi the flange, said wire not being of quite sufficient length to complete the circle, one end th. .eof being secured to a hug 13 which projects through one or": the slots 11, its other end being secured to a slotted plate 14;. This end also is provided with a lug; 15 which pro 'jects through one of the slots 11, and other luos 16 are also secured to the wire and 31'0- 0 c Ject through other slots 11, all 01 these slots and engaging lugs being designed to movshade holder. These lugs may be formed ably seat the spring, in place within the if desired, by bends in the wire 12.
To the slotted plate 14-, one end of a lever 17 is rel'novably, or rather adjustably, se-
cured, its outer end being pivotally secured at 18 to an L-shaped lever 19, which is itseli retatably secured to the other end of the wire 12, the outwardly projecting end of the lever 19 projecting through one of the slots 11.
In practical operation the lip of a shade 20 is inserted in the shade holder within the wire 12. The lever 19 is then thrown over contracting the ring around the lip of the shade, the movement of said leverbe- .ingsufiicient to carry the pivotal mounting 18 past the rotatable mounting of the'lever to the end of the wire 12, thus firmly clamping the wire to the lip of the shade and locking it in this position. I
It is obvious that the slotted plate 1d, to which the lever 17 may be removably secured, provides an adjustment for the diameter oi my wire holding means, so that it may be lengthened or shortened to fit any desired shade.
.ll aving described my invention what I regard as new and desire to secure by Letters Patent is:
A shade holding attachment comprising the combination with a bell-shaped holder of an annulus of spring wire mounted within said holder, at lug which projects through a slot in, the wall of the holder to which one end of the wire is secured, a slotted plate to which the other end is secured, a plurality of other lugs mounted in other slots in. said holder vwhich movably seat said wires, an L-shaped lever to which said plate is rotatably attached, said lever being rotatablv secured to one end of said wire.
In testimony whereof, I have signed the foregoing; specification.
