LOUIS HEINZE, OF LYNN, MASSACHUSETTS.
HOLDER FOR INCANDESCENT ELECTRIC LAMPS.
QPECIFICAI'ION forming part 0f Letters Patent No. 343,313, dated June 8, 1886,
Application filed November 20, 1885. Serial No.183,397.
To all whom it may concern.'
Be it known that I, Louis HEINZE, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Holders for Incandescent Electric Lamps, of which the following is a specification. l
This invention has reference to animproved holder for electric incandescent lamps, by means of which the expensive leading-in wires of platinum, that connect the light-giving carbon at the interior of the lamp-body with the exterior copper wires, are dispensed with and copper wires used in place ot' the same, and wherein the point ot' electrical contact between the leading-in and the exterior wires can be clearly seen; and the invention consists of a holder for electric incandescent lamps which is made of a tubular body of glass having thin metallic contact-plates extending longitudinally through the same, and ot' an in-` candescent lamp the bulb of which is provided with an elongated glass stem, and copper leading-in wires that pass through the stem and are bent up along the same, so as to form contact with the metallic plates of the holder.
In the accompanying drawings, Figure l represents avertical central section of my improved holder i'or incandescent electric lamps. Fig. 2 is a top view of the holder with the lamp detached; and Fig. 3 is a horizontal section on line x a, Fig. I.
Similar letters of reference indicate corresponding parts. I
Referring to the drawings, A represents an incandescent electric lamp of any approved construction, the body or bulb of which is provided with a solid or tubular glass stern, B, that is equal in length or longer than the bulb itself. The leading-in wires a c pass through the stem B, and are melted into the same, and are connected at the inside of the (No model.)
are attached in any suitable manner to a tubular socket or holder, C, and extended longitudinally through the same. The holder C is made of plain or colored glass, or other suitable transparent material, and in plain or ornamental shape, as required. The lower part of the socket C is provided with a screwthreaded sleeve, d, by which it is screwed into any suitable support. The conducting linewires are soldered or otherwise attached to the lower ends of the grooved contactplates b b, the latter being placed in electric contact with the outer ends of the leading-in wires a.
In place of the expensive platinum leadingin wires copper wires are used, by which the desired result is accomplished without detriment to the vacuum in the lamp'body, as, owing tothe length of the stem, thelower part of the same and the copper leading-in wires are .but little affected by the heat of the incandescent carbon, so that consequently but a small amount of contraction or expansion of the leading-in wires takes place.
By constructing the stem and holder each of glass the contact between the bent-up ends ot' theleading-in wires a and the grooved plates b can be clearly seen through the same by looking through the spaces between said plates.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The glass socket C, provided with the longitudinallyfgrooved metallic plates a on its interior for connection with the line-wires, in combination with an incandescent lamp,A,
having a glass stem, B, the leading-iu wires LOUIS HEINZE.
