To all whom t may concern.

Be it known that we, WILLIAM L. KORN# .FELD and ARTHUR R. ENGLANDER, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Shade or Globe Su porting Means, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a shade or globe supporting means for use with electric lights, and has for its objects to provide mea-ns which may be readily applied to a standard type of socket and firmly locked thereto so as to edectually support thel weight of a shade or globe; lto provide a device of this character which is neat and attractive of appearance and which con-l ceals a part of the socket and so harmonizes with the portion revealed as to produce a pleasing effect; to combine with a, shade holder of the foregoing nature an adapter which may be attached to the holderin the same manner as a shade is attached thereto and which, in turn, incorporates globe sustaining means; and to constitute of said adapter a reflector whereby the efiiciency of the light is increased.

The foregoing objects with others hereinafter appearin are attained in the 'embodiment of the invention illustrated in the accompanying drawing wherein Fig. 1 is a sectional side elevation of a lighting fixture equipped with the device of our invention showing it supporting a globe in proper relation to anvelectric' amp; Fig. 2 is a side elevation, at right angles to Fig. 1, of the shade holder `ap lied to the lamp socket; and Fig. 3 is a plan view of what is shown in Fig. 2.

' An electric lamp of usual type is represented at 1 and the same is supported from a socket 2. The socket is of common form, comprisin a shell 1 that telescopes at its upper en 4 vwhich is suspended, t from a wire concealing tube -6.

Our improved shade holder consists of a bell shaped casin 7 which is of a diameter at its upper en to fit ,snugly about the upper end of the shell 1 and abut the lower ledge of the enlar ement 3. A bail 8 is connected, by suita le pivot means 9,

into an enlargement 3 of a cap*` rough its boss 5,

notch 10 for the accommodation of said boss. The side branches of thebail 8 are enlarged laterally to provide wings 11 that are formed to snugly embrace the enlargement 3, the forward edges of the wings being flared outwardly slightly, asindicated at 12 in F ig.V 3, to facilitate the bails slipping over the enlargement. The casing 7 is notched at 13 for the reception of the shank of a key 14; and atits lower edge is equipped with shade attaching means which are shown, in the present instance, as screws 15 that are threaded through the edge portion of the casing.

It will be readily understood that a shade '(not shown) may be applied to the holder by inserting the neck of the shade upwardly into the lower end of the casing7 and projecting the screws 15 inwardly into engagement with the neck, in accordance with common practice.

In the same manner an adapter 20 is attached to the holder. This ada ter is shown as substantially frusto-conical in shape, terminating at its u `per end in a neck 21 and at its lower en in a vertical flange 22 through which globe supporting means in the formv of screwsA 23 are extended, the flange beinlg shown as provided with bushings 24 t rough which the screws are threaded. This adapter is articularly suitable for use with a specia form of globe which in the drawin is desi ated generalll by the numera 25. T e globe of itsel y It has a neck 26 at its upper end that is adapted to be received within the lian e 22 and to be enga ed by the screws '23.' v to contour, the g obe 1s curved outwardly. and downwardly below'the neck 26 a suit-l able distance to a point designated by the line A-A, and for a sui/table distance below constitutes no part of our invention.

thisl point to a point designated by line B-#B vsemi-spherical shape. Above the line A--A,

and below the line'B-B, the globe is trans'- lucent; while between said lines it is transparent or clear. This results in a sort of semi-indirectl 1i hting effect, certain ra s from the lamp ing reflected Idownwar y llO/r/ direction, of course, direct raysA escape through the clear ortion of the'` globe. While it is desirab e to soften the rays descending from the lamp throu h the translucent lower portion of the glo e, too

much filtering of the light is extravagant and' objectionable and to increase the eiiiciency of the light penetrating the lower portion "of the globe to a very considerable extent we finish the inner surface of the adapter 20, particularly the frustoconical portion thereof, to a very high brilliancy, as by silver plating and polishing in the manner of finishing reflectors of usual type, so that the rays which would otherwise be lost are redeemed and cast downwardly, the majority of them falling through the lower portion of the globe while some are cast olf through the transparent zonev between the lines A-A and vB--B. A

It is 'clearly' within the scope of our invention to alter the shape of that portion of the adapter 20 hereinbefore referred to as :truste-conical, itv being apparent that such portion maybe curved axially and, if desired, given the contour of a parabola.

Also', the adapter and shade holder may be constructed as a single unit without departingl from the spirit of our invention. Such modifications as those sug ested are so obvious as to make specific illustration of them unnecessary. i

Having thus described our invention, what we claim is:

1. For use with a lamp socket having a circumferential enlargement, a globe holder comprising a casing designed to fit over the lamp receiving end of the socket and concealed the same and have its inner end engaged with said enlargment, and fa' bail hingedly connected to opposite sides of the casing-and -adapted to be swung over the end of the socket remote from the lamp receiving end for positively holding the casing against withdrawal from the socket,

I the casing being 'provided with globe attaching mea s.

2. A shade holder for use with a lamp socket having a circumferential enlargement, the holder comprising a casing adapted to be slipped over the lamp receiving end of the socket with its inner ends in engagement with the enlargment, while its opposite end is provided with shade attaching 'means, and a bail pivotally connected to op osite sides of the casing and arranged to e swung over the end of the socket reyend in engagement with the enlargement,

while its opposite en'd is providedA with shade attaching means, and a bail pivotally connected to opposite sides of the casing, the bail having a notch for the reception of the neck of the socket when the bail is swung into operative position, the opposite branches of the bail having parts frictionally engaging the enlargement of the socket to hold the tion.

4. A shade holder for use with a lamp socket having a circumferential enlargement intermediate its ends and terminating at its inner end in a neck, a casing adapted to be slipped over and' conceal the outer end of the socket and to have its inner end in engagement with the aforesaid enlargement, while its opposite end is provided with shade attaching means, and a bail ykpivotally connected at its ends to diametrically opposed parts of the casing and hav'Y ing at its middle a neck embracing notch adapted to receive the neck of the socket when the bail is in operative position, the branches of the bail having laterally extending wings which are formed to embrace the enlargement of the socket thereby to hold the bail in operative position.

5. A shade holder for use with a lamp socket having a circumferential enlargement and provided at its inner end with a neck, a substantially bell-shaped casing adapted to fit over and conceal the lamp receivlng end of the socket and arranged to have one of its ends ab t against the aforesaid enlargement, the o posite end of the shell incorporatinor shade attaching means, and a bail pivotally connected at its ends to diametrically opposed parts of the casing and having a notch which embraces the neck of the socket when the bail is in 0perative position, the bail being formed so as to cooperate with the socket in such manner as to be held by frictional engagement therewith in operative position.

In testimony whereof, we hereunto afiiX our signatures.
