6 Claims.

} invention will be understood from the following description considered in connection with the accompanying drawings formand in which:

a perspective view of the preferred of an adapter of the present inven- Fig. 1 is embodiment tion;

' Fig. 2' is an elevational view, partly in crosssection, showing a washer type shade secured to a bulb by the adapter of this invention; .Fig. 3 is a partial sectional view on an enlarged scale, taken substantially on line 3-3 of Fig. 2;

44 of Fig. 5;

Fig. 5 is a partial top plan view of Fig. 4; v Fig. 6 is a view similar to Fig. 4 but showing the shade engaged by the adapter ata lower position; v .Fig. 7 isapartial elevational, sectional view showing a bridge type shade secured to a bulb by the adapter; and a I Fig. 8 is a partial vertical sectional view of a shade secured to a bulb on abridge type lamp base by the adapter.

,.Like characters of reference refer to like or similarlparts throughout the several views.

Referring to the drawings, reference character A designates generally an adapter embodying the present invention. The adapter consists essentiallyof a bulb engaging portion and a lamp shade engaging portion. The bulb engaging portion comprises two spaced incomplete rings l and II of resilient wire in substantial alignment with each other. The ends of the bulb engaging rings l0 and I I are secured to the lamp shade engaging projecting from the center portion of the upper edge of the rectangular portion and lying substantially in the same plane therewith. The extension I is provided with a laterally extending flange l6. As shown, the rings I0 and II are secured to the plates M by rolling the lateral edges of the plates around the outer end portions of the rings into secure engagement therewith. The ends of the rings I1 and I8 which extend (Cl. 240-138) v beyond plates tially the same portions l9 and formed if desired.

The rings l0 and H are formed with a diameter such that they will-snugly engage an electric light bulb in the manner shown in ,Fig. 2. The dimensions of the plates l4 and the end portions of the rings l0 and II are such that they will readily and securely engage the inner peripheral portion of bridge or ring type shades and the dimensions of the extensions I 5 are such that they may readily be inserted in the relatively small apertures in a washer type shade and will securely engage the inner peripheral portions thereof. The rings l0 and II are preferably made of resilient steel wire with sufiicient resiliency to permit their lower portions to be spread apart in a direction transverse to their planes and to be sprung over an electric light bulb and further to permit their end portions, or the plates M, to be moved toward each other to the extent necessary for them to properly engage the inner peripheral portion of the annulus of any lamp shade, whether bridge, ring or washer type. The rings lll'and Il may be madefrom any material suitable for the purpose and may have cross-sectional configurations, other than circularfwhich 'are suitable for the purpose intended. At such times as the adapter is not in engagement with the annulus of a shade, the plates l4 'are'preferably disposed at a distance apart which is normally greater'than the inside diameter. of any lamp shade annulus to be engaged by the adapter, so that when the plates M are brought togetherand into engagement with the annulus of a shade, the rings exert a force on the plates tending to force them apart and into secure engagement with the annulus.

Figs. 2 and 3 illustrate the adapter utilized for mounting a washer type lamp shade to a bulb.

l4 are bent outwardly in substan- The bulb B is supported in an upright position I the pressure exerted by the resiliency of therings l0 and II. The flanges I6 effectually prevent the adapter from accidental disengagement with the washer. After the adapter has been secured to the shade, the

the bulb B and the shade is thereby securely mounted on the bulb. r

rings l0 and II are sprung over mount a ring type shade on a bulb. The ring 28 is secured to the outer shade ring 25 by spokes 21 as with the, washertype shade. :As shownin these figures, the extensions l5 of the adapterare engaged with the inner peripheral portion of the ring 28.

Fig. 6 shows [4 of the adapter so the bulb at a lower Figs. 4 and 5 where the ring 28. y

Fig. 7 illustrates the ad'apter'used to-mount a plates, 14 are in engagement with the inner threaded portion 30 of the annulus 3 l' which is se cured to the outer shade ring 2j5 by thespokes 21'. "If desired however, the adapter maybe disposedwith respect to the shade sothat the'extensions l5 engage the annulus 3|,in which event the shade will be mounted on thebulb B in a higher position than asshown' in-Fig. '7. a The 3' of: the rings H! and H prevent adapter with ends I! and' accidental disengagement of th the annulus 3L.

Asshown in Fig. 8, the adaptermay also be utilized to secure a'r'ingl type lamp shade to a bridge lamp. Bulb 3 is threaded in a socket 32 supported by theusual bridge lamp arm 33. As shown, the ring 28 is engaged by the extensions H) but may, of courseya's previously mentioned, be

engaged by the plates l4 if'a lower position of the.

shade with respectto the bulb is desired. With.

this arrangement, the shade is supported with the upper end at the ,contact end of the bulb. This arrangement may also I be utilized to'mount any shade havingv aring to'be engaged by the adapter, which is large enough to'fit over the bulb socket, on aso-called drop light that'is, on a bulb suspended from a cord or rod or the equivalentsupportingmeans. V From the foregoing, itwill be seen that I have provided meanswherebyany v V shade may be mounted on an? electric light bulb which is supported. in any position. And with the exception of, the washer v shades maybe mounted on the b lbs attwo dif-- ferent heights. The, advantages ofthe' adapter to sellers of lamps andlamp shades-will be ob-- viouS' .1, Q It will be apparent that the'adapter herein disclosed may be modified so as to provide any given height of the shade with respectto the bulb on which it is mounted and may also be arrangedso that more than two different heights may be effected. I Inasmuch as many modifications'of the former the adapter herein disclosedmay be made without departing from ,thefprinciple'of the invention, it will be understoo'dthatf I entertain'no intention to limit the invention except'by the scope of the claims hereto appended. i, 1
