- New York, haveinvented newand useful Improvements in Shade-Holders; ofwhich the following is a description.

My inventionpertains to thatclass of devicesknown as shade'holders intended'to hold a shade or bowl in proper operative re lation to some source of illumination.

My invention has for its particularpbject to provide a shade holder of simpleconstruction by means of which the 'sh-ade may be "readily clamped into position and by a simple operation lock'ed'into such" position so as to be firmly retainedin operative relation to the source" of illumination until it is desired that itshall be-removedand it is a further object of myinvention that the removal of the shade may be at any time accomplished in a simple and easy manner.

Referring to the drawing Figure lrepresents a vertical section of a shaddholder comprehending my invention. Fig. 2 shows with outwardly turned flanges 1 and the fingers 2 are provided with inwardly flanged portions 5, vertical sections 6 and extensions 7 bent to conform with the flange or top of the shade intended to be held in the shade holder as will hereinafter be more fully explained. The portions 6 are provided with outwardly projecting lips or bosses as indicated at 8 which may be struck up by means of a proper die from the material The function of these members 8 will hereinafter be explained.

9 represents an annular ring adapted to slip over the cylindrical portion 1 and rest upon the feet or flanges 4: of the fingers 3.

10 is a metallic ring having cam shaped inner surfaces 11 and adapted to be passed over the fingers 7 until it registers with the vertical portions 6 and is restrained from further movement by the flanges 5.

The rings 9 and 10 are united by the spac- Fig. 3 is a perspective showingcin.

ingmembers 12, which may be rigidly secured to saidringsand on'eof which memhere has attached thereto the handle or thumb-piece13 whereby the said members maybeeasily rotated. The cams 11 have near their point of smallest diameter slots 1 1 adapted to engagethe members 8 as shown plainly in Fig. 2.

15 represents portion of the shade held 1I1 plaee-by'my'shade holder.

The operation of my improved shade holder is substantially as follows: The memb'er'l isattache-d to" anysuitable type of fi xtivre or support which also carries the source of illumination and to which it is desiredfto attach=theslrade If the handle l be swung so as to revolve the rings 9 and 10 into such-position that the fingers 7 may ea pgan d outwardly to the point of greatest diameter in the ring 10 the shade 15 may then be 'slipped between the-fingers 7 and tlrenif' the-handle 13 b'esomoved as to revolve the rings 9 and 10 so that the diameter of'the cams 11 in'contactwith the portions Gshall decrease, the fingers 7 will be forced inwardly upon the flange of the shade so as to hold the same firmly in place: hen

the fingers 7 make contact with the flange of the shade 15 further revolution of the ring 10 will cause the portion 6 of the fingers to be forced inwardly and the fingers to yield or spring and when the ring 10 has been sufficiently revolved to bring the members 8 in register with the slots 14: the members 8 will spring into said slots and hold the ring 10 from revolving unless considerable force be applied to the handle or thumb-piece 13 thus preventing the shade from rattling out of the holder under the influence of severe vibration as is met in use upon railway trains for which use my shade holder is particularly applicable. If desired to remove the shade the handle 13 has simply to be swung to the increased diameter of the cams 11 when thefingers will open and release the shade. The same may be replaced as above outlined.

From the foregoing it will be obvious that I have produced a shade holder of simple construction and of a strong and durable type which may be manipulated very quickly to grasp or disengage a shade and which when engaging a shade will be locked in its operative position in such manner as not to be rattled loose when vibrated.

form of shade holder comprehending my invention for it is obvious that considerable changes may be made in the construction of my shade holder without departing from the spirit of my invention which is as set forth in the following claims:

1. A shade holder consisting of a baseportion having projecting therefrom shade supporting fingers; a plurality of flanged fingers carried by the base-portion; and movable means supported by said flanged fingers and surrounding said supporting fingers for pressing each finger individually into engagement with a shade.

2. A shade holder comprising a base-portion provided with depending, shade-supporting means; a plurality of flanged fingers carried by the base-portion; and rotatable means supported by said flanged fingers and having devices for engaging said supporting means adapted to press the latter into engagement with a shade.

3. A shade holder comprehending a por-- tion provided with projecting fingers with out-turned flanges, a ring resting upon said flanges, a plurality of projecting fingers adapted to engage a shade, movable meansfor operating said fingers and means uniting said movable means with the above mentioned ring,

4. A shade holder comprising a base portion, a plurality of flexible fingers projectplurality of circularly arranged resilient fingers, some of the fingers being longer than the others and the long and short fingers being alternately arranged; extensions carried by the shorter fingers, and the longer fingers being provided with grooved eXtremities for engaging the flange of a lamp shade, and means carried by theextenslon's of the shorter fingers and engaging with the longer fingers for altering the position of the latter.

6. A shade holder comprising a cylindrical member having longand short fingers extending therefrom, the short fingers having supporting means and the long fingers having engaging means; a device carried loosely upon the supporting means of the short fingers and engaging the long fingers; and means by which said device may be turned relatively to said fingers to alter the position of the long fingers.
