a 1 Beit know-n thatLQROBERTYFARlES, of Decatun lnthe county-ofMacon and State of ,Ill1no1s, have invented certain new and use-* ful lmprovemenfts'in Adjustable'Oarriers for Electric Lamps, of which the following isa specification;

This invention relatesin part to an exten- 9 a g r; in'partto a' swinging *arn1',-'and n part to the hanger andarmin'eombination; 1t 1s exempllfied 1n the structure hereinafter described, andis defined. in the ,a ppended claims. I p

, y In the-drawingsformingpartof this speci fication Figure l-is an elevation ofv the hanger vandhof two swingingarms connected there-- i i i Fig; 2" is a'central vertical section I through the upper end of the hanger; Fig. 3

ameter of, tube 1.

is a similar section through an intermediate Fig. 4 is a like section part of i the hanger. through the inner end of a swinging arm and the part of the hanger with which it connects. Fig. 5 is a' plan of the joint with which the arm is preferably provided.

1 is a tube which connects with the ceiling, or other support, through the intervention of flanged collar 2 and screws or other fasteners. 3 is a collar which is secured to the lower end of tube 1, and such collar has a contracted opening through its lower end.

4 is a tubeof smaller diameter than tube 1; it extends into tube 1 through the contracted opening of the collar 3, and it is provided on its inner endwith a head, 4", which approximately conforms to the internal didis a bracket, flange, or enlargement on I the lower end of tube 4, and such bracket has yso l l a perforation,'or perforations, as seen at 5 in Fig. 4. Rod 6 formsone part of the swinging arm, it is tubular throughout its entire length, though not necessarily so, its diameter is very little less'than the diameter of perforations 5, and its inner end 7 is hooked as shown and inserted through a perforation of the bracket. The outer end ofrod 6 is forked, as shown in Fig. 5, and the forked forated at their ends.

9 is a tubular rod which is preferably bent in the form of a goose-neck at 11, and which 7 carries the socket of lamp 12. The inner end of rod 9 is forked, and the forks 10 are perportions, 8, 8, are per-,

1 forated toconform'to the perforations of forks 8. {To form theljoint between rods 6 and 9 the forked ends are placed in tlie position shown in Fig. 5, a .sleeve,115, isplaced hetween forks '10 and 10, threaded bolt 13 is inserted through the perforations of the forks,- and through the sleeve, and the nut 14 is screwed onto the bolt. 7 The nut is preferably "supplied. with jfinger bar 14 whichenables the'nut tobeset up against the forks with considerable force. j The sleeve 15 holds: the forks from collapsing, after the manner'of a strut, and the boltand nut, when tightened,

through head 4 into tube 4, it passes out of tube 4-.through a side opening in the lower end of the tube,'and it connects with the lamp develop sufficient friction to make thejoint socket through the tubular arm. "There is.

sufficient slack in the cord between the arm and tube 4 to permit free vertical swing in the arm'andlamp, and the strands of the cord pass one on each side of sleeve 15, thereby holding the cord in place in the joint. A pin, 22, which is preferably in the form of an inverted cone, extends downward intothe upper end of tube 1 and into the coil of the cord, and av similar pin, 17, extends upward into the coil from head 4. Screw 21 passes through a threaded hole in a side of tube 1,below head 4, and its inner end acts as a stop against the lower surface of the head to limit the down- Ward motion of tube 4. Spring 18 is secured at its lower end to the inner surface of collar 3, screw 19 being employed tomake the connection, and its upper end bears against tube 4. Set screw 20 extends through the collar 3,

its inner end bears against spring 18, and it is Fig. 3. The pins 22 and 17 hold the upper and lower, ends of, the coil in proper shape and position at all times, and their tendency is to prevent the coil from becoming disarranged or entangled as tube 4: is raised. The arm may be swung horizontally and yerti cally in bearing 5, rod 9 may be swung to form any desired angle with rod 6, and the tube 4 maybe moved up and down. The arm is held in different positions in collar 5 by the Weight of its outer end, which cramps the curved end in its bearing; the rod 9 is held by friction developed by the bolt, the nut and the sleeve; and the tube 4 is held bythe trio, tion developed by spring 18. The arm may be swung horizontally by a push, but toadjust it vertically the ,outer end istsustained and the curved end moved lengthwise in the bearing; a;

- The ditferentparts coact to good ad vanta 30 tion and particularly point out the peculiart ties that I desire to cover by Letters Patent.
