SPECIFICATION forming part of Letters Patent 110,349,516, dated September 21, 1886.
Application filed January 11. 1884. Serial No. 117.125.
To all whom it may concern.-
Be it known that I, CHARLES G. PERKINS,
a citizen of the United States, and a-resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Electroliers, of which the following is a specification.
My invention relates to a class of wall and ceiling fixtures, commonly called electroliers, having arms for holding electric lamps and lamp attachments.
In illustrating the first part of my invention I have shown a single tube, which I term the support, carrying metallic tubes in the interior thereof, which I term conducting tubes. These tubes are held in position and insulated from each other by means of an insulating material, such as wood, rubber, fiber, 0r plaster-of-paris. receive a sliding metallic rod split at the upper end and sprung outward, so as to produce a friction on the interior surface of the conducting-rods, thereby insuring a perfect electrical contact therewith.
In illustrating the second part of my invention I have shown a single tube, which I term the telescopic tube, the upper end of which carries a friction-spring, which spring bears against the exterior surface of the supportingtube. The lower end of the telescopic tube is provided with a shoulder carrying a unionnut, which engages with screw-threads made on the neck of a hub. The hub has an annular concaved track on the exterior thereof corresponding with a like structure made on the under side of the annular rim of the case having the lamp and switch holders fixed thereon. These tracks are held one above the other by means of a number of balls playing within the concaved portions thereof when revolving the portion carrying the lamp and switch holders.
In illustrating the third part of my invention I have shown a block, made of suitable material, held within the above-named hub by means of screws. The said block is provided with metallic standard-nuts for the reception of the aforesaid metallic rods. The standardnuts are electrically connected separately with a metallic ring partly embedded in the base of the block, said metallic rings engaging with These conducting-tubes (No model.)
fiat friction-springs fastened to metallic rings secured to a second block of insulating material rigidly fixed to the revolving case named above. These rings of the second block of in- 5 sulating material are provided with metallic projections, which pass through the block of insulating material to the base thereof, where they are electrically connected with the conductors leading to the lamps.
In the drawings,Figure 1 represents a vertical section showing the principal features of my invention. Fig. 1 represents a detail view of one of the sliding rodsfshowing the split end thereof. Fig. 2 represents an elevation of the exterior. Fig. 3 is a plan of the second block of insulating material, showing the flat frictionsprings mounted thereon. Fig. 4 is an inverted plan of the second block. Fig. 5 is a plan of the block of insulating material secured to the hub Fig. 6, an inverted plan thereof. Fig. 7 is a plan of the hub, showing the con cave track thereon, and partly filled with balls.
Similar letters refer to similar parts throughout the drawings, in-whicha represents the hanger.
bis the supporting-tube containing the tubes 0 c, which are insulated from each other and held in position by plaster-of-paris, d.
e e are the electrical conductors connected with the tubes 0 c.
d d are the metallicrods provided with split ends, and adapted to slide and make frictional contact with the interior surfaces of the tubes 0 c. Said rods are secured to the standard-nuts ff, one of which is electrically connected with the metallic ring 9'. The standard-nuts f f and metallic rings 9 g are secured to the block of insulating material h, which is rigidly fixed to the hub '5, provided with the track 70 on the exterior thereof.
l are the flat metallic springs, each separatcly fastened to metallic rings n, secured to the second block, 0, of insulating material. Said rings are provided with metallic projecg5 tions 19, which pass through the second block to the base thereof, where they are electrically connected with the conductors 1 and 2, leading tothe lamps.
s is the revolving case having secured there- ICQ to the arms 8, which support the lamp and switch.
t is the concave track made on the under side of the rim t of the case 8. Both the tracks k and t are separated from each other by means of balls k, over which the track t glides.
u is the telescopic tube carrying the frictionspring u at the upper end thereof, where it is held in position by means of the nut 11.
3 is the shoulder integral with the telescopic tube u, which shoulder supports a union-nut, u, screwed onto the neck4 of the hub i. The upper end of the telescopic tube is also provided with an offset, 1), which comes in contact with the annular offset 1)" on the lower end of the supportingtube I).
5 is a cap adapted to be screwed onto the case 8.
The arms 8 are provided with swivel circuitconnections 8', whereby the lamp may be turned in any position desired. However, I donot claim this to be a new feature, as I have made application for Letters Patent for the same some time since. The turning of case sin a horizontal plane is possible, because of the relative positions of the frictional springs and plates 9 g I, always maintaining the electrical contact, and the elevating and lowering of the electrolier can be accomplished by means of the split tube and the inclosing-tube.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In combination with an electrolier, a supporting-tube containing metallic conductingtubes insulated from each other, the conducting-tubes adapted to receive a metallic rod provided with means on the upper end thereof adapted to produce frictional contact with the interior of the conducting-tubes, both tubes and rods forming a part of the circuit-connections of the electrolier.
2. In combination with an electrolier, a hub provided with means for carrying electrical circuit-connections, an annular track on the exterior of the hub, a case carrying the arms for the lamps and circuit-connections of the structure, and the annular track secured to.
neck 4, concave track k, balls 70, concave track t, rim t, case 8, and arms 8.
4. In combination with an electrolier, a block of insulating material secured within the fixed portion of the distributing-box of the electrolier, the lower surface of the block provided with metallic rings, forming a part of the cir'cuitconneetions of the electrolier, and the block of insulating material secured within the revolving case, forming a part of the distributing-box, the upper surface of the block provided with frictional contact-springs adapted to bear against the metallic rings secured to the block within the fixed portion of the distributing-box, said contact-springs electrically connected with conductors leading to the lamps. 4
5. In combination with an electrolier, sub stantially as shown and described, theinsulating-block h, standard-nuts f f, metallic rings g g, flat metallic friction-springs Z, metallic rings n, second block of insulating material,
0, metallic proj ections p, and electrical conductors 1 and 2. V
6. In combination with an electrolier, a telescopic tube carrying a means at the upper end thereof adapted to bear against the exterior surface of a supporting-tube secured to a hanger, the lower end of the telescopic tube provided with means for connecting it with the arm-support of the electrolier.
7. In combination with an electrolier, the
telescopic tube to, friction-spring u, not 1;, offset 12', shoulder 3, and union-nut u.
Signed at New York, in the county of New York and State of New York, this 8th day of January, A. D. 1884.
