Patent ed Aug. 25, 1914.

Application filed February 15, 1913. Serial No. 748.5%.

To all whom it may concern lie it known that l. (iconen A. ltiaonn'rir, a citizen ot' the United States. residing at Pittsburgh. in the county ot' Allegheny and State ot' Pennsylvania, have invented certain new and useful Improvements in Light ii1g-l1`ixtiilies. of which the following is a specification.

This invention relates to lighting fixtures and has particular reference to the provision or' improved means for holding and support ing canopies and lamp shades, one ot" the chief objects of the invention being the provision ot' a combined'lalnp shade and canopy holder which is simple and rigid in construction and which may be readily assembled and taken apart. My invention further contemplates the provision of a shade and canopy holder which maybe readily adapted for use on fixtures o`f` different sizes and which permits ot ready adjustment.

Another object of the invention resides in the provision of a` shade and canopy holder which is rigid in construction and maintains the shade, canopy, and lamp in proper relation with respect to one another. These together with such other objects as may herenafter appear, or are incident t'o my invention, l attain by means of a construction which I have illustrated in preferred 'torni in the accompanying drawings, wherein- Fig. l is a side elevation of a. canopy and lamp shade illustrating the application ot my invention'thereto; Fig. 2 is a section through the device illustrated in Fig. l; ltig. 3 is an enlarged vertical section through my improved holder; and Fig. 4 is a section similar to that ot Fig. 2 but illustrates a modification ot' my invention.

Referring particularly to Figs. l, 2, and 3. it will be seen that l have shown a canopy T which is adapted to coverl the hase otl a cell ing and wall fixture, and a lamp shade b, the canopy and thefshade being maintained in proper position by means ot my limproved holder which will now be described.

'llhe holder comprises a metal shell or husk 9 which is provided with an aperture l0 in. the top portion thereof to permit otx the insertion of the threaded stem il, one end of which is threaded into the base ot the lamp socket l2 and the other end threaded into the buckle 13 through which the wires lfl are led to the socket l2. 'lf he buckle 113 is connected to the pipe 15. located in the ceiling or wall 16 by means ot' an insulating connection l?. t will he noted that b v this construct-ion the lamp socket is rigidly held. ibo husk or shell 2) is securely clamped into position against; the end ot the socket l2 by means of the nut lo and is rigidly held thereby while at the same time the socket l2 may he adjusted on the stem il. In order to prevent the stern ll from `turning in the hnckie lil as the parts are being assembled I provide nut 19 which is threaded onto the stem li and abuts the buckle 18. The lower portion of the husk 9 is provided with threads 2O and is adapted to receive the threaded holding socket 2l which ispio vided with a shoulder 22 and a depending flange 23. The canopy T rests upon the collar and the shade 8 is held in position in the tiange 2? by means ot' the screws 24 which engage the shade adjacent the 'lip The parts are assembled in the following manner7 assuniing that the stein ll carrying the nuts 1S and 19 has been screwed into the buckle 13:

rlthe husk 9 is slipped over the end ot' the stem ll and the socket 12 then screwed onto the stem, the nut 1S being tightened up to clamp the husk into position. The canopy 7 is then slipped over the husk and the socket 2i is screwed onto the husk and serves to hold the canopy in position. The. shade S is then inserted within the lian ge S23 and locked into position.

.From the foregoing it will be apparent that the; device is compact and simple and that the parts may be readihl assembled and are adjustable to compensate lor any irregularities in the shape or size ol the canopy. lhe parts are all standard and the holder may be extended in length toaeconuuodate Fixtures otl different sizes by the substitution ol a husk of diilerein'i length. the device thus being not only adjustablevbut also extensible. .further advantage ot the device resides in the 'tact that all the, parts are, rigidly secured together and maintained in proper position with respect to one another and the use olf supplementary means 'i'or locking the eanopv in position is dispensed with. .\uother iniporta'nt feature olE the invention resides in the tact that przwtieally all ot the metal parts are inelosed by the canopy which is preferably made ot glass or other noueorrosive substance. the cleaning ol the metal partsI thus being obvialed aud the general appearamle and neatuessl ol*I the fixture. being,r greatly enhanced.

BCI

I'Ieretofore the canopy has been located above the lamp socket and fastened in place by supplemental holdin0` means, and the shade has been secured to a holder fastened on the lamp socket. In this construction difficulty has been encountered in maintaining both the canopy and the shade in proper position, this being particularly the case in wall brackets or fixtures. By my improved construction I have not only overcome this defect but have also added to the appearance ot' the fixture.

Referring now to Fig. et it will be seen that I have illustrated a construction in which the entire holder is inclosed by the canopy and shade and covered from view. I accomplish this by forming on the flange 23 of the socket 2l a collar 26 which is adapted to engage the shoulder 27 formed on the lamp socket. In this construction the construction is the same as that previously described and has the same advantages. readily cleaned and are sanitary.

I claiml. A lighting fixture comprising in combination a support, a canopy, a shade, and a holder carried by the support adapted to support both the canopy and the shade, said holder comprising a member secured to the support and a second member detachably secured to the first member, said second member having a canopy holding portion and a shade holding portion.

2. A lighting fixture comprising in combination a support, a canopy, a shade, and a holder carried by the support adapted to support both the canopy and the shade, said holder comprising a shell secured to the support and socket detachably secured to the shell, said socket having a canopy holding portion and a shade holding portion.

3. A lighting fixture comprising in combination a support, a canopy, a shade, and a holder carried by the support adapted to support both the canopy and the shade, said holder comprising a shell secured to the support and socket having threaded engagement with the shell, said socket having a shoulder adapted to support the canopy and a flange adapted to support the shade. Y y

4. A lighting fixture comprising in combination a support, a canopy, a shade, and a Both forms of the fixture can be holding device adjustably mounted on said support and extending within the canopy and adapted to support both the canopy and the shade the said holding device comprising two parts which are adjustably secured together.

A lighting fixture comprising in combination a stem, acanopy, a shade, a holdingy device for supporting the canopy and shade having an aperture to receive the stem, a lamp socket threaded to the stem, and a nut adapted to clamp the holding device against the socket.

6. ."i lighting fixture comprising in combination a support, a socket carried by said support, a shell inclosing said socket and hung therefrom, a shade, and means on the shell for supporting said shade, and means for locking said shell in position.

LA lighting fixture comprising a support projecting from a wall, a socket mounted on said support, a shell surrounding said socket, a canopy, and a shade, the said shell having means for supporting the canopy and shade and being adjustably mounted on said support for adjustment toward or from the wall whereby the canopy is firmly held between such supporting means and the wall.

S. A lighting fixture comprising in combination a support, a canopy, a shade, and a holder carried by the support adapted to support both the canopy and shade, said holder comprising a member mounted for adjustment on the support and a second member .mounted for adjustment on the first member, said second member having a canopy-holding portion and a shade-holding portion. i

9. A lighting fixture comprising a support projecting from a wall, a canopy, a shade, and a member having supporting means for the shade and the canopy mounted on the support for adjustment toward and from thewall whereby the canopy is firmly held vbetween the wall and said means.

In testimony whereof I have hereunto signed my name inthe presence of the two subscribed witnesses.
