Specification of Letters Iatent.

Patented Aug. 15, acre.

Application filed July 16, 1915. Serial No. 40,248.

To all whom it may concern:

Be it known that we, SAMUEL Newman,

acitizen of the United States, and HENRY R. BoT-HwnLL, a subject of the King of.

Great Britain, residing at Cincinnati, in the county of'Ha-milton and State of Ohio,

have invented certain new and useful Im provements in Lamp-Supports of which the following is a specification.

()ur invention relatesto light supports; and its object is to more conveniently and ing shown in Fig. 1; Fig. 4 is a general perspectiv'e view of a modification of 0urinvention, Fig. 5 is a vertical cross section corresponding to Fig. 2, but showing a modification of the frictional holding means insidethe tubel l The extensible aim of the support comprises an upper tu ular member'l and a lower member 2 which need not'be tubular,

and which slides into the interior of the upper member 1? The-upperend of the upper tubularmember 1 has a spherical head 3yfined to it by-means of a shank 4 fixed in a central bore in the head 3, extending "into theupper end of the member '1, and

I soldered or otherwise suitably fixed therein.

This spherical head 3 bears upward in the mounting 5 whicl1,;as here shown, comprises an innerdo'me 6 and an outei'.shell' 7, both of which are substantially-circular and con-- a is centric, and these parts being joined by a bottom 8 that extendsout from the lower rim of the dome 6-to the lower end of the shell-Y all around. The dome 6, around inside itslower rim has a part (S -that conforms to; the spherical head 3 andlthereby forms abea'ring forsaid head 3; while-the' upper end of the shell 7 is left open, and its rim preferably extends slightly above the, top of the dome 6, this upper rim of the. shell 7 being the means that makes contact with the ceiling or other object upon which the mounting is secured. Preferably, this upper rim of the shell 7 is provided with lugs 9 that extend up and are adapted to become indented in the material of the ceiling or other object, and through the top of which; a screw 10 may be passed up into the ce llngor other object, this opening 10,

the dome 6 there is an opening 10 through as shown, being countersunk to receivean I ordinary fiat head screw. Thus, a single screw through the opening 10, in eon3unction with the lugs 9, will hold the mounting up on the ceiling or other object and also prevent it from turning around. the screw.

To hold thesphericalhead 3 up in its hearing in the lower rim of the dome 6, a collar 11 has a slight downwardly turned annular flange 12 that bears around on the spherical head 3, and it has a peripheral upwardly turned annular flange 13 that fits neatly around the outsideo-t' the lower end of the mounting 5.- Screws ll pass up through the collar 11 into the bottom 8 of the mounting '5 and draw the collar 11 up against the spherical head 3 with anydesired degree of tightness. be removed from the mounting 8 and allow the spherical head 3 to be taken fromrils bearing without removing the screws 14, the collarll has its openings throughwhich In order that the collar 11 may the screws. 14 pass in the form. of a combination of a circular hole 15 and a slot 16 cont municating with and extend ng from one side of the hole circumferentially around the collar for a short-distance, all of these The holes 15 are large enough to allow the heads of the screws 14;, to pass through" them, but the slots 16 are only about wide enough to allow the passage of the shanks of the screws into these slots. Thus, the col [the screws 14 slightly in Eider to remove and replace the ieollar, but at the same time it will not, be necessary to removethe screws theassemhlage and disassemhlage of-the sup port convenient for sthrage', transportation and subsequent illStallcltll L; Thus con-g structed, the spherical head; fwillhave its 99. slots 16 extending from the respective holes I P5 .in thesame direction around the collar.

Preieriibly, no positive clamping means is provided for the lower member or rod .2 in the upper tubularmember 1 bill: these ports ere held together frictioiiolly so that the lower member may be very conveniently slid Up or down in the upper member. As here ehoii'ii this frictional holding means bone-lobe of. ii resilient Wire 17 iiil'edin the upper end of tberod 2 and. curved old: of :iliiiilioeoiwwith the rod. ind tube 1 for enough litioliiiso it to beer with its middle end 19 ogoioot substanpoei te eidee oi the interior of'lhe l Willi considerable force, and thereby iill'ord the friction required to hold the rod :2 stationery in the tube 1 at any position is slid in said tube .1. The foot Eli) comprises a piece of sheet metal with two iilined lugs 20 turned down i E from ii iii; one side, and one log 2G" turned down from it at the other side of its juncliioii wilh llie lower member 2. A. U-ehopeil member fill has :1 long leg 21' and a short. leg Ell. The long leg 21 extends through ported by the lhiii'iib' lull and is guided aimed lugs 20" screwed onto ll where it pro and on pjeole book: through the lugs 20. The short leg 21" extends through and is supported by the other log 20" at the other side. This foot is adapted to admit the noel; of lhelemp 23 and the cord 2% by bringing the U-shapecl member 21 for enough forward to allow the end of its short log -21 to escape from the log 20". ee indicated by the dotted lines in Fig. 3.

Tosupport the cord 24; in upright position for a considerable dieloooe up from the lump, ii cord holder 25 is formed of a wire or rod, preferably somewhat thinner than the rod 22,'lmving ii lower eye at right angles from its lower end and emand having on upper eye 27 embracing the upper ii'ioml'lor or tube 1. This upper eye 27 lies at right angles to the main part of the cord sn 'lport 25, but joining it to this moin piu'tie on open loop 28 formed by the wire or ro l. This loop 28 per-mils the lamp ooi'il 24 to he elid into it; and when the rod 2 is adjusted up and down in the tube 1 the upper eye 27 of the oord support 25 will slide up and down on the tube, the lower eye Qii bearing down against the foot 520. Thus, wliiil'ovor upward and dowmi'ard mljiieliment of the lump, the cord will always be held up by the loop 28 of lhe cord holder 25 amply for to be out; of the way of ialio user of the lamp.
