JACOB REESE, OF PITTSBURG, PENNSYLVANIA.
INCAN DES'CENT LAM P.
SPECIFICAI I QlLforming part of Letters Patent No. 415,335, dated November 19, 1889.
Application filed August 8, 1887.
To aZZ whom it may concern.-
Be it known that I, J ACOB REESE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Incandescing Electric Lamps, of which the following is a specificanon.
In the construction of incandescent lamps through which the current returns and passes out at or about the point at which it enters, the wires, carbon, or filaments pass near each other, and a considerable loss of electrical energy is experienced, due to conduction through the attenuated atmosphere of the lamp.
My invention relates to a special form of incandescing lamp for obviating this disadvantage by interposing between the ingoing and outgoing branches of the filament an insulating-partition by locating them, respectively, in separate chambers of a twin lamp, said chambers being arranged side by side, with a single common intervening Wall.
In the accompanying drawings, Figure 1 represents a central section of my twin incandescent lamp, and Fig. 2 represents a crosssectional view thereof on the line 'y y of Fig. 1.
In the figures, 0. a represent the two sepafierial No. 246,455. (No model.)
rate chambers of the glass lamp, each of said chambers having open ends adapt-ed to be closed by the sealing-plugs b, and having a single common separating-wall n interposed between the filaments ff.
The leading-in and outgoing wires are indicated by the letters 01 6, respectively, and h indicates the connecting-loop between the two chambers.
The form of twin lamp shown is quickly and cheaply manufactured, and the common partition, besides acting as a separator between the two chambers, gives considerable strength to the structure as a whole.
Having thus described my invention, what I claim is- A twin incandescing lamp consisting of the separate chambers a (1, having a single common dividing-wall at, each chamber having openings at its opposite ends for the reception of the sealing-plugs b b, substantially as described.
JACOB REESE.
