To all whom it may concemi Be it known that I, THOMAS A. EDISON, of
Menlo Park, in the'county of Middlesex and order to insure economy of material in the conductors therefor the incandescing portion is usually of very high resistance. The resistance usually given them is sufficient for any desired economy in ordinarily thickly-settled 1ocalities. For use, however, in sparsely-settled neighborhoods-as, say, the outskirts or suburbs of a town or city--it may be desirable to have a lamp by the use of which still greater economy of conductor is attained. In such localities, in order to lessen the number of lights needed in streets, it may be also desirable to have a lamp in which the volume of light is increased, inorder that economy in the erection of lamp-posts, 850., may be subserved; and it may also be desirable to use lamps in which the volume of light may be increased in other localities. As there is eventually a limit to the effective life of the carbons used, it seems desirable to so arrange a lamp that the operative life of the lamp may be prolonged beyond the average life of a carbon, to the end that the cost of the labor expended in embodying a carbon in a lamp may be reduced.
The object of this invention is to furnish a lamp which will accomplish the results set forth, as desired, to which end it consists in the features more particularly hereinafter set forth and claimed.
An inclosing-globe' is used, made and put together in the usual manner of my lamps. To the inner end of one of the'conductors leading into the lamp is fastened a double clamp that is, one which is Y-shaped, a carbon being fastened to each limb of the Y-clamp. At the other end each carbon is fixed in an individual clamp, each clamp having its own conductorleading outside of the lamp. The wires leading out of the lamp and the wires leading from a suitable source of electricity are united at a circuit-controlling device constructed so that it may close the-circuit through either carbon, the circuit through the other remaining open; or it may close the circuit through both, as carbons in a series; or it may close a circuitthrough each, thecircuits through them being derived or multiple-arc circuits.
ln the drawing (one figure) such a lamp is illustrated.
A is the glass globe, and B the supportingneck united at a 1). Through the neck B passes the conductors 6 7 8, which are sealed therein. Upon the inner terminal of 6 is the Y-shaped clamp D, in each leg of which is fixed a carbon, e or g. The other ends of these carbons are in separate clamps, ebeing fastened in the clamp 11 of conductor 8 and g in clamp d of conductor 7. These conductors, 6, 7, and 8, and the circuit-conductors 5 9, are connected to a key, E, composed of contact-points 1 2 3 4 and anvils m 82, as follows: Circuit-conductor 5 is connected to point contacting with w, and to anvil s, on which 2 contacts, while 9 is connected to anvil z, with which both 3 and 4 maymakecontact. Conductor6isconnectedto anvil w, 7 to point 4, which contacts with z, and
contacts with 2. If points 1 and 3 be put in contact with their anvils w z, a circuit is formed, 1
from 5, via 1 w 6 D e d 8 3 z, to 9, the circuit through 9 being open, and 0 only being used for the production of light. If 1 and 4 be closed on a; and z, the circuit is from 5, via. 6 D g d 7 4 z, to 9, the circuit through 6 being open and g alone in circuit and use. If 2 and 4 be closed on s and z, the circuit isfrom 5, vias28cDg74z,to9,and bothcandgare in one circuit-that is, in series. If 1, 3, and 4 be closed on w, s, and z, the' circuit is from 5, via 1 w 6, to D, where two paths are found, the current consequently dividing, one circuit being D e 8 3 z, to 9, the other,D g 7 4 z, to 9, both carbons being in circuit, but each havin g its own circuit, which is a derived one, so far as the main circuit is concerned. When both are used in multiple arcit is evident that the net resistance of the circuit is one-halt the resistance of one, and a certain sized conductor is required. If both are used in series, the resistance is double that of one and four times that of the multiple arc, in which case the conductor may be diminished three-fourths. As the volume of light is that of two ordinary lamps,it is evident that a much less number may be used with the same light-giving result. Thus economy in laying main conductors and in the erection of lamps is secured.
It is evident that as one carbon only may be used at a time, by so using one only at a time the life of a manufactured lamp is practically doubled, for where one carbon has. reached its efl'ective limit the circuit therethrough is transferred to the other, thus saving the expense involved in sealing one carbon in its globe, the cost ofa globe, and of its exhaustion.
It is evident, while only two carbons are shown, that more may be sealed in one globe, 1) being provided with the same number of clamps, and each carbon provided with a separate return-wire, for which proper connections are made by enlarging keyE on the principle shown.
It is also evident that E may be provided with lever-contacts, instead of the screw-contacts used to explain the principle of my in- "ention.
I am aware that it is old to place two or more carbons within one chamber a'n'dconnect them so that they shall be rendered incandescent simultaneously, and that it is old to place several carbons in one lamp to be used successively. Therefore I do not claim such.
What I claim is 1. The combination, in one electric lamp, of two or more incandescing conductors, a single electric circuit leading thereto, and a circuitcontroller therein, substantially such as described, adapted to connect the incandescing conductors in series or in multiple are, as may be desired, substantially as set forth.
2. The combination of a single electric circuit, an electric lamp containing two or more incandescing conductors,and meansfor throwin g the current through any desired incandescing conductor independently of the others, substantially as set forth.
' 3. The combination,in one electric lamp, of
two or more incandescing conductors, a single electric circuit leading thereto, and a circuitcontroller therein, substantially such as described, adapted to complete circuit through either of the incandescing conductors independently of the others, or through all simultaneously, substantially as set forth.
. 4. The combination of an incandescent electric lamp containingtwo conductors arranged 7th day of August, 1880.
