SUSPENDING DEVICE FOR ELECTRIC LAMPS.
SPECIFICATION forming part of Letters Patent. No. 340,512, dated April 20` 1886.
I Applicalion filed December 14, 1885. Serial NoA 19543151. (No model.)
To all whom it may concern:
Be it known that I, 'PAUL KRAUTZ, engineer, a subject of the King of Prussia, residing at Berlin, Prussia, German Empire, have invented cert-ain new and useful Improvements in Suspending Devices for Electric Lamps and l Chandeliers; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention relates to incandescent electric lights, and the purpose thereof is to provide the same with an improved construction which will allow of the lamps being raised and lowered without the necessity of employing free hanging wires, thereby avoiding the aunoyance heretofore occasioned by such wires being brought in contact with each other or with parts of the chandelier-fitting.
My invention is applicable to a stand containing two or more lights, and may be used in combination with xed lamps as well as with separately-movable lamps.
My invent-ion consists in the several novel features of construction and combinations of parts hereinafter fully described, and definitely pointed out in the claims annexed to this specication. l
Referring to the drawings forming part of this application, Figure l is a view partly in elevation and partlyin section, illustrating my invention. Fig. 2 is a partial longitudinal section of Fig. l, enlarged. Fig. 3 is a crosssection of the same, enlarged.
In the drawings the reference-letter a designates an outer tube,provided with an external thread, a', at the top, which engages with a female thread in a socket-piece, b', mounted on a short tube,b, having a diminished threaded end, which receives a nut, b2, by means of which a hook, c, may be attached in the manner shown.
Upon the lower end of the tubes a is formed a screw-thread, awhich engages with a thread upon a cap, d, closed at its lower end. The
stationary or fixed lamps are attached to the y closed end of this cap, as shown in Fig. 1.
, Within the tube a, and extending the entire length thereof, are placed two strips, f, made of any suitable nonconducting material. These strips serve to hold and insulate rods e coeX- tensive with the length ofthe strips, and made of copper or other suitable conducting material. These rods are each soldered at the upper end to one of the electric service-wires e', which pass through the tube a, and are connected in the usual manner to the line-wires. The two rods are braced by rings f and j2 at top and bottom, made of ebonite, rubber, or
other non-conducting material.
Upon the rods e slide segmental pieces g, having grooves which receive and iit the rods. These pieces, which are of any conducting material, are attached to and move wit-h a core-piece, h, made of wood or other non-conducting material. This core-piece is mounted upon a tube, k, into which pass the wires t', soldered to the contact-pieces g. These wires pass down the tube and to the lamp Z, where the usual. connection with the contact-key or switch is made. There is sufficient friction between the contact-pieces g and the rods e to hold the lamp Z at any point to which it may be adjusted. This construction secures not lonly the result of giving proper contact between the conductors, but also'provides sufficient friction to retain the lamp at any point.
Within the cap d is placed a ring, n, of wood or other non-conducting material, into which ring are set two half-rings, p, insulated from one another, and each of which is connected with one of the rods c by means of a short wire, o. A wire passes from each of the half-rings p 'through the hollow brackets q, which are mounted on the closed end of the cap d, and thence connect with the lamps Z/ mounted on the iixed brackets q.
It will be seen that the rods e subserve three distinct purposes: First, they conduct the current to the fixed lamps; second, they serve as conductors in the tube a, and, finally, they carry the current to the lamp l, besides giving friction to the core-piece and its contacts to enable it to sustain the lamp l.
Instead of a single movable lamp,I may use a number electrically connected by separate half-rings in a manuel' similar to that already described.
Instead of an incandescent, I may use an are light, and I may also wholly dispense with the stationary or fixed lamps.
l. The combination, 'with the outer tube of a suspension device for electric lamps, of longitudinal segmental strips of nonconducting material, vertical stationary conducting-rods located in said strips, service-wircs connected with said rods, a tubular lamp-carrying rod provided at its inner end with grooved contact-pieces engaging and sliding on the conducting-rods with frictional contact, to hold the tubular rod in any position to which adjusted, and electrical conductors attached to the contact-pieces and entering into the tubu. lar rod, substantially as described.
2. In a verticallyadjustable electric lamp, the combination,with a tube, insulating-strilis therein, and conducting-rods mounted on said strips, of a core-piece carrying contacts sliding ou the conductors, Wires soldered to the contacts, a tube attachedto the core-piece and containing said wires, and a lamp carried by the tube.
3.. In an electric light, the combination, with a tube, insulatingstrips contained therein,and conducting-rods mounted on the same, ofa core-piece carrying contacts and sliding on the conductors, wires soldered to the contacts, a tube attached to the core-piece and containing said Wires, an insulating-ring beneath the conductingrods, conducting-pieces set in said ring and connected with the rods by wires, and stationary and movable lamps, the latter on the tube and the former on fixed brackets, substantially as described.
In testi mony whereof I aix my signature in presence of two witnesses.
PAUL KRAUTZ.
