ELECTRIC-LIGHT SHADE.

Specification of Letters Patent.

Patented Jan. 10, .191 1.

Application filed July 26, 1910. serial No. 573.915.

To all whom/it "mag concern:

Be it known that I, CLIFFORD C,- CARPEN- rnn, a citizen of the United States, residing at Seattle, in the county of King and State of lVashington, have invented certain new and useful Improvements in Electric-Light Shades, of which the following is a specification.

The object of this invention is to provide an exceedingly simple and inexpensive form of shade adapted to be readily attached to and detached from the sockets to which ordinary electric light bulbs are secured.

The invention involves particularly a shade comprising a suitableopaque body which is carried detachably by a simple form of clamp, the latter being conveniently arranged for engagement with the light socket aforesaid.

For a full understanding of the invention, reference is to be had to the following detail description and th accompanying drawings, in whichv Figure 1 is a View showing an ordinary electric light invention supported thereon, the shade being shown in section; Fig. 2 is an elevation of the shade and its supporting member, the clamp members being omitted; Fig. 3 is a plan view showing more particularly the clamp device; about on the line H of'Fig. 2, and Fig. 5 is a modification, being a View similar to Fig. 1.

Throughout the following description and on the several figures of the drawings similar parts are referred to by like reference characters.

In the drawings, 1 denotes the socket adapted to receive the e ectric light bulb 2, the latter being adapted to be screwed into the socket in the customary way and coin taining the usual filament The shade attachment comprising this invention composed of four essential parts, namely, the shade member shown at 4, a supporting member 5 secured thereto, and two clamp members 6.

It is contemplated that the shade 4: may be made of any suitable opaque material or substance, but said shade is preferably formed from sheet metal and is of concavoconvex-*form in cross section. An opening is formed at the central portion of the shade by pressing the metal outwardly as shown at.

4 and the supporting number 5 consists of bulb and socket having the- Fig. 4 is a section taken a length of wire, the lower end of which 'is j bent upwardly to provide a hook 7 which passes through the central opening of the shade 4. The hook 7 is of peculiar shape in order that it may be so engaged with the shade 4 as to prevent loosencss of the latter when suspended adjacent to the light by means of the member At its upper portion, the hook 7 is formed with a bend 7', providing a recess on the inner side of the hook, and adjacent to said recess the metal or material from which the shade 4 is made is formed with a U-shaped projection 4", the latter being preferably pressed out Wardly from the metal as shown clearly in the drawings. .Vhen the shade 4 is supported on the member 5, the bond 7 of the hook 7 engages over the lower portion of the projection 4.", and the upper extremity of the hook is seated between the sides of said upward displacement of the shade from the member 5, as well as lateral play of the shade.

The supporting member 5 has its upper end passing through coinplemental pivot lugs integral with each of-the clamping members 6, thereby pivotally connecting said clamping members. The upper peripheral portion of the shade 4 is cut out or recessed as shown at 8 to provide a clearance space for the finger pieces 6 of the clamping members 6. The cut out portion of the shade may also serve as a clearance space to receive the body of the socket 1 in' the manner shown in the modification in Fig. 5 should it be'dcsired that the shade illustrated in said figure be permitted to assume the position shown.

, The stmcture illustrated in Fig. 5 is substantially'thc same as hereinbefore described excepting that the clamping members and the shade are arranged in slightly different relative positions, and the hook 7 of the supporting member 5 is of slightly diflerent form, having the protuberance 5 to engage the central apertured portion of the shade 4 to subserve the rigidity of theconnection between the supporting wire or member 5 and said shade.

A spring 9 is interposed between the finger pieces 6 of the clamp members 6 to normally cause the latter to move toward one another.

Having thus described the invention,what is claimed as new is: v

1. A shad: attachment of the class deprojection, thereby preventing accidental shade comprising a Wire having one end bent to form a hook passing through the aperture, a clamping device connected with said su porting member, the shade being provide with a projection engaging the hook of the supporting member to prevent play of the shade when mounted thereon.

2. A shade attachment comprising a shade provided with an aperture therein, a supporting member consisting of a piece of wire having one end bent upon itself to form a hook passing through the aperture, said hook beingprovided with a depression in its length, the shade being formed with a U shaped projection pressed. outwardly therefrom and the curved end of which is received in the recess of the hook' preventing accidental displacement of the shade from the supporting member, the sides ofthe U- shaped projection being arranged at opposite sides of the hook tonevent lateral play of the shade,suspende thereon, and clamping members pivotally mounted on the upper end of the supporting member aforesaid, the shade being recessed at its upperportion adjacent to the clamp members to Ol'IIla clearance space as speclfied.

In testimony whereof I afiix my signature in presence of two witnesses.
