1912. Serial No. 670.358. i

To all 'iff/"mm it m fly com-erw Be it known that I, Pn'rnu (ooinu Hnwi'r'r, a citizen of the United States. and resident o1 Ringwood Manor', county ot' Passaic, State of New Jersey, have invented certain new and useful Improvements in Vapor illectricLamps and Connections, of which the following is a specification.

The present invention relates to an elec trical apparatus in which a suitable gas or vapor inclosed in a transparent container isr made luminous by the passage of electric current. The type oi' apparatus illustrated is adapted for various uses, and the novel features of the said device Will be explained in the specification and fully set forth in the claim.

The illustrations, Figures l and show similar types of electrical apparatus of this sort, the main di'eren'ce appearing-in the electrical connections for the lamp.

The container consists ot a tube, l, of glass or other transpz'xrent material, provided with electrodes, 2, 3, and et. The electrode 2 is here shown as a body of solid conducting material. such as iron, while the electrodes 3 and 4 appear` as small masses of mercury. Any suitable materials may besubstituted for those-named. The electrodes 2 and 1 are mounted at'the opposite ends of the tube 1, and the electrode 3 is contained in a small pocket/ 5, Formed on the container l about midway of its length. The device is provided with a chamber G at thel top sefl'vin r as a cooling or condensingi chamber whereby the vapors formed in the operation ol the. lamp are condensed and the general capacity oi the device. for radiating heat is increased.

ln big. 1, the electrodes '2. and 3 are connected with the, positive side of an electric vcircuit and the electrode l with the negative side. in Fig. il. the electrode 2 is positi ve and the electrodes Il and l are negative. l may interpose suitable resistances or indue tance. devices. 'l and-8; in the ivircs leading to the electrodes( as may be desired or re.-` quired for dillcrent uses of the apparatus and for steadying the. operation thereof.

ln the lamp illustrated in Fig. 2, it is 'This is found to be found that the raporin the lower part of the lamp is denser than in the upper part, the quantity ol current passing throiigh the said lower hal'l being approximately double that passing through the upper half. The apparatus may be used in testing the operations which take place in aninelosed gas or vapor carrying electric current, or it may be utiliz/.ed 'For producingv diilerent eii'ects in ,li1i'erent parts of a single inelosing chamber.

Figi'. i2 is made use ot simply to Yillustrate a -diii'erent set of connections for the electrodes. and it will be understood that these connections may he still further varied to suit diliercnt requirements, at the will of the operator.

ln operating this lamp the mercury which is condensed in the chamber (3 is redistributed for condensation, passing down the tube into the pocket 5 and overilowing from that pocket .into the lower part of the tube and there a valuable 'feature of the lamp and' is one oi" the features constituting the present invention.

This application is a division of my application iled March 19thj 1903, Serial Number 14H.51)i; issued on January 16, 1912, as Patent Number 1.014.705. and a ci'nnpanion to my application filed "July lith, 1911, Serial Number 637.951. issued on January 1G, 15112 as Patent Number 1,014,965, which is also a division oi the first named application.

l claim. as my invention A vapor electric device tical tubular portion. a condensing chamber at the top thcreoi'. a solid anode within the said chamber and a plurality of vaporizable cathodes disposed at intervals within the vertical tube. the said vaporizable electrodes being connected together outside the tube..
