SEALING IN OF WIRES FOR INCANDESCENT LAMPS.
SPECIFICATION forming part of Letters Patent No. 358,492, dated March 1, 1887. Application filed (Tune 20, 1855. Serial No. 169,278. (No model.)
To all whom i1? may concern.-
Be it known that I, MARMADUKE M. M. SLATTERY, of \Voburn, county of Middlesex, State of Massachusetts, have invented certain 5 new and useful Improvements in Sealing in of Wires for Incandescent Electric Lamps, of which the following is a specification, reference being had to the drawings forming a part hereof.
The object of my invention is to save time, trouble, and expense in the formation and insertion and securing into their globes of the glass-supports used to lead in and secure the platinum or other wires conveying the current to and upon which is mounted the continuous incandescent conductor of carbon or other material. Heretofore such pieces or supports have been formed and the wires inclosed therein and let into the globe in various ways, such as by placing the wires on opposite sides ofa rod, plaeingatube outside, and incorporating the whole together; by passing the wires through the walls of a glass bulb sealed into the globe by mercury joints, and in other modes. I find, however, that these methods are all open to objection, and that my im proved process is simpler, quicker, cheaper, and quite as efficient as, if not more efficient than, any of the other methods.
My improved process consists, briefly, in taking two glass tubes, welding them together side by side, placing at thesame time in the depression on each side of their point of contact a rod, (so as to furnish more stock or ma- 3 5 terial,) drawing the whole out to the necessary degree of fineness, and afterward cutting the double tube thus formed into proper lengths, into which the leading-in wires are sealed, the support or piece thus formed being afterward o sealed to the sides of the opening in the lower part of the lamp-globe.
Referring to the drawings, I take, in the first place, two tubes, A A, and two rods, B B, and place them as shown in the end view, Figure 5 1, welding them together side'by side into one piece. This, being heated, is then drawn out until sufficiently reduced in thickness, the tubes and rods still, of course, retaining their relative position, but becoming more closely incorporated together, which may be also assisted by compressing the tubes and rods together while hot. The double tube thus formed is divided into suitable lengths and the leading-in wires a sealed therein. This piece or support can then be readily sealed into the lamp-globe. Fig. 2represents one ofthe pieces or supports carrying the leading-in wires, and ready for sealing into the globe, and Fig. 3 is a section of a completed lamp with the support sealed therein.
My invention is not necessarily restricted to cases where two wires only are led into the globe, but may with slight modifications be applied to the manufacture of lamps in which more than one carbon or other incandescing conductor is used.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The process of forming supports for leading-in wires for globes for incandescent lamps, consisting of the following steps, viz-z welding together tubes and rods side by side, drawing the same out until sufficiently thin, and dividing the same into suitable lengths.
2. The process of forming leading-in pieces for globes for incandescent lamps, consisting of the following steps, viz: placing two tubes together side by side, adding rods or other pieces, as shown and described, welding the whole together, drawing the same out until sufficiently thin, dividing the same into suitable lengths, inserting the leading-in wires into the tubes, and heating and sealing the wires and tubes together.
3. The process of sealing leading-in wires into globes for incandescent lamps, consisting of the following steps, viz': welding together tubes and rods side by side, as described, drawing the same out until sufficiently thin, divid- 9O ing the same into suitable lengths, sealing into one of such lengths or pieces the leading-in wires, and then sealing such piece carrying the wires into the, globe.
