SHADE-HOLDER.

SPECIFICATION forming part of LetterstPatent No. 601,829, dated April 5, 1898.

Application filed June 1, 1897. Serial No. 639,471. (No model.)

To all whom it may concern:

Be it known that I, MORRIS D. GREENGARD, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Shade- Holders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Myinvention has relation to improvements in shade-holders for electric incandescent lamps; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims. I

In the drawings, Figure 1 is a top plan View of the holder. Fig. 2 is a section on line 00 a: of Fig. 1, and Fig. 3 is a section on line y y of Fig. 2.

The present invention is an improvement on the construction of shade-holder set forth in my pending application for Letters Patent, Serial No. 611,878, filed November 12, 1896, and has for its object to materially simplify the construction therein set forth, whereby the cost of manufacture of the holder will be greatly reduced. In detail it m ay be described as follows:

Referring to the drawings, 1 represents the shaderingtha t is, the ring to which the shade is directly secured, and which may be done in any approved mannerthe said ring having connected thereto a series of pairs of fiat webs 2, inclined inwardly to the general plane of the circle of the shade-ring, one member of each pair of webs being connected at its upper or free yielding end with the nearest member of the next adjacent pair by a bandsection 3, having an upper flaring edge 3, the several sections forming collectively a clamping-band by which the socket of the lamp can be seized or embraced and the flaring edge serving to guide the holder over the socket. The members of each pair of webs, or rather their outer edges, normally diverge slightly from the point of their connection with the shade-ring, the resiliency of each member and its tendency to diverge. away from its adjacent member being increased by the cut-away portions 3" at the base of each web, which removal of the metal at that portion has a tendency to remove the stiffness from the member, rendering the latter yielding and more resilient. Each pair of webs is embraced by a slide 4, having a terminal rounded embracing portion 4:, which while it firmly embraces the web at the same time enables the slide to pass over any burs that might be left along the edges of the same as a result of the stamping operation of the dies from which the holder is cut. The slide when moved along the webs toward theclamping-band causes the web members to be drawn toward each other, thus bringing into closer relation the adjacent ends of the adjacent sections 3 of said band. (See full lines in Fig. 1, the dotted position showing the clamping-band open.)

In this way the clamping-band can be made to firmly embrace the lamp-socket. The several slides are operated by the upturned win gs 5, which may be seized by the hand of the operator. The friction of the slide upon the web members serves to hold the former in any position upon the latter. A notch 6 is out along the base of each section 3 near its j unction with the web 2, thus permitting the slide t to be shifted along the webs to the highest position, where it will more positively draw together the adjacent ends of the contiguous sections of the clamping-band, drawing, as it does, on the bands along approximately the medial longitudinal lines thereof.

Having described my invention, what I claim is 1. In a shade-holder, a suitable shade-ring, a sectional clamping-band forming a part thereof, a series of pairs of flat webs having outer inclined edges connecting the sections of the clamping-band t0 the shade-ring, a slide having rounded terminal portions embracing the webs, the bases of the webs being cut away to increase the resiliency of the same,

substantially as set forth.

2. In a shade-holder, a suitable shade-ring, a clamping-band, webs connecting the band to the shade-ring, the bases of the webs being cut away at their juncture with the shadering, substantially as set forth.

3. In a shade-holder, a shade-ring, a clamping-band, and flat webs having outer inclined or diverging edges connecting the shade-ring to the clamping-band, the bases of the webs being cut away at their juncture with the shade-ring, substantially as set forth.

4. In a shade-holder, a suitable shade-ring,

a sectional clamping-band forming a part thereof, a series of pairs of fiat Webs rigidly connecting the sections of the band to the 5 shade-ring, the Webs having outer inclined edges normally diverging from the shade-rin g toward the clamping-band, a slide embracing each pair of Webs and adapted to draw the same together upon movement thereof in one [0 direction, the flat faces of the Webs being inclined to the planes of the circles of the shadering and clamping-band, substantially as set forth.

In testimony. whereof I affix my signature in presence of two Witnesses.
