duced by the first. 1 The two lamps shown in Fig. 1 are con- 85. For convenience of description, it will be nected in series. In the operation of this assumed that a lamp is employed in which class of vapor lamps, it is sometimes desirthe main portion of'the light is produced by able that a steadying resistance be connected mercury vapors and thatit is desired to su in series with the vapor lamps, and in such plement it with a spectrum having a sulfiinstances the incandescent lamp, connected cient abundance of red rays. as in Fig. 1, well serves this purpose.
The present application is a division of an .To render the gas or, vapor lamps suitable gpt lication N 0. 11,608, filed by me on the for general use u on commercial circuits, 1t day of April, 1900, the prior application is desirable that t ey should receive currents illustrating and describmg an a par'atus in under the influence of moderate electromowhich the above described res t is accomtive forces and possess within themselves the plished by combining or associating with the capacity of self regulation with respect to the mercury vapor, a vapor or gas such, for inamount of current received.

The lamp is further treated by properly heating the electrodes and creating such chemical reactions therein as would be liable to take place in use, and drawing ofl the impurities and deleterious materials and subjecting the lamps while in the process of manufacture to the class of currents with which they are to be operated, and introducing within the tubes, the proper amount of vapor or light emitting materials. In the present application claims are not made upon the method of constructing the lamps, and, it will not be necessary to enter more in detail into the method of construction and manufacture.
For the purpose of starting lamps of this character, it is usually desirable to employ an initial higher potential for producing within the lamp such a condition on the part of the vapor as Will cause it to receive currents of the potential with which it is designed to be operated. To accomplish this any convenient arrangement of circuits may be employed, and in Fig. 2, wherein I illustrate a mercury vapor lamp in parallel with an incandescent lamp, I have shown one organization of such circuits.
The lamps 1 and 11 are connected across main circuit conductors 24 and 25. In the conductor- 20 there is included the coil 22 of a suitable spark-coil or reactive device, the core of which is represented at 23. A con ductor 26, including a switch 27, leads from one terminal of the coil 22 to the main con ductor 25, the arrangement being such that the coil 22 may be placed in closed shunt across the circuit 24, 25. A suitable con denser 28, of any desired form, is connected in shunt around the switch 27. When the switch is closed, an electric circuit is"com pleted through the coil 22, and upon breaking the conductor 26 a high difference of potential is established at the terminals of the lamp 1, and the result of this is to create such a condition on the part of the vapor column as to cause the current from the con ductors 24 and 25 to How easily through the lamp and operate it.
Referring again to Fig. 2, a switch, 30, is introduced into the conductor 20. A switch, 33, is also introduced into a conductor 35 running from the main conductor, 24, and also containing a resistance, 34. The con ductor 35 is connected beyond the switch to the conductor 20.
In still another application filed January 18, 1908, Serial Number 411,384 as a division of the same parent application above referred to, claims are made upon other features of the system herein disclosed.
I claim as my invention:
1. The combination with a U-shaped vapor lamp having electrodes, at least one of which is vaporizable, the operating )osition of the said lamp being one in which t 1e arms of the U are lower than the bend, of a cooling chamber located above'the bend and a neck or constricted portion connecting the cooling chamber and the main body of the lamp.
2. In combination, a vapor lamp in the shape of an are or arch, the said lamp being adapted to give a definite spectrum, and a lam adapted to give a different spectrum, the l ast named lamp being located within the are or arch of the other lamp.
3. In combination, a mercury vapor lamp, in the shape of an are or arch, and an incandescent lam in series therewith, the said incandescent iamp being located within the are or arch of the mercury vapor lamp.
