tions.

A further object is to provide a single means for holding the several lamps in their 'disks on said socket-member.

adjusted positions.

Another object is to provide means for adjustably supporting a lamp shade with respect to the lamps.

l attain these objects, as well as others not specifically stated, by means of the construction, arrangement and combination of parts hereinafter described.

In the accompanying drawings ing my invention;

Figure l is a front elevation of a support cmborilying my invention;

Fig. 2 is a fragmentary side elevation of the adjustable mounting; and

Fig. 3 is an enlarged fragmentary view partly in section on the line 3-3 of F 2.

Referring to the drawings, 1 indicates a standard which may be supported in any suitable manner, as, for example, by the base 2 shown in F g. 1. The standard is formed of two tubular sections or parts hav ing' their adjacent ends secured, at diametrically opposite points, toa ring-like n1emher or casing 4-, which member constitutes a socket for the adjnstable lamp supporting illnstrat-' arms 5. Flexible wires W extend through the standard 1 and the arms 5, as shown in ll igj. 3, to carry the current to the lamps L.

The arms 5 are substantially tl-shaped and are mounted in nipples 6 formed on the pair of oppositely located disks 7. Said disks are provided with annular flanges 8 disposed adjacent their marginal edges, and which into the socket member at, as seen in Fig. 3, so as to permit of rotation of the The disks are perforated axially to receive a bolt 9, hav ing a knurled head 10 which abut-s against one of the pair of disks and nut ll. which abuts against the other. The boltand nut serve to hold the lamp carrying arms adjustably in position. i

A rod 12 fits telescopically into the upper part of the standard 1 and is provioed with a collar 13 to support the usual lamp shade (not shown). A collar is rigidly mounted on the upper end of the standard 1 and carries a thumbscrew 15 which" impinges against the rod 12 so as to hold the lamp shade at any desired elcvation'within the range of adjustment of the rod.

As illustrated in Fig. l the inverted shaped arms face or extend in opposite directions with the two lamps'L lying on opposite sides of the standard 1. in the era treme upper or lower adjusted position of the arms the ends thereof will strike against the sides of the standard, thus'limiting the range of adjustment of each arm to an arc of slightly less than 180. This prevents the arms from being accident; lly turned to such an extent as to break the feed wires.

It will be noted that by loosening; the nut 11 the disksjl, which carry the lamp sup porting arms, may be turned so as to adjust the lamps in ditterent angular positions relative to the standard or to each other. lit will also be observed that either lamp may be adjusted independently of the other and that the single nut 11 serves to maintain both lamps in their adjusted positions,

Various changes and modifications may be made in tho CZ-nnbination and arrangement of parts herein described, Without departing from the scope of my invention as pointed out in the claims.

Whatl claim is:

' 1. In an electric light support. a standard provided with a ringdike member, a pair of disks revolubly mounted on opposite sides of said member, J-shapcd lamp supporting arms secured to" said disks, said arms being disposed on opposite sides of the standard so to engage the latter and be restricted in their movement thereby, and a bolt extending axially through the disks and ring-like member and having a not for clau'ipingly l'lolding the disks against said member.

In an electric light support, a standard, a member carried by the standard below the top thereof, a pair of disks mounted on op relation thereto, lamps carried. by the disks,

and. u, singlu means for holding both 0f the disks against turning movement.

3. in an electric light support, a hollow humlm'd a ring likc member carried by the standard, hollow lamp carrying arms, disks supporting said arms and mounted on 0pposite sides of said member, means to {uljustably secure the disks to said member, and lamp Wires passing through the standard and ring-film member into the arms of 10 the disk.
