APPARATUS FOR PRODUCING -VCI'L'LLAIC HIGH-CURRENT ARCS.

T 0 all whom it may concern-.- 1 Be it known that I, HARRY PAULING, a

subject of the German Emperor, and resident of 84 VVilhelmstrasse, in Gelseiikiiclien IV, iii-the Rrovince of Vl estphalia, Kingdom.

- of Prussia Germanvhave invented certain new and useful Improvements in Apparatus for Producing Voltaic High-Current Arcs, of which the following is, a specification.

My inventionlrelats to apparatus for the production of voltaichigh-current arcs and i more particularly to device "of the kind in whichthe arcs are produced y means of diverging electrodes and by a currentfofogas which blows the discharges, umpmg the space of greatest proximity-of the electrodes, along the latter so as to form arcs of the required great lengths, which'break and extinguish after having attained a definite length.

The length of the arcs mainly depends, on

one hand, upon the length of the elec-' trodes and upon the angle between the lat-.

ter, while on the other hand it is largely dependent on the strength of current supplied to the electrodes, and on the force of the said current of gas inasmuch as arcs of great length require an accordingly great amount of energy as well as the action of an accordingly strong current of gas, as will be readily so seen. I strength to be considered in this res ect re- Electric currents, however, of the quire the electrodes to. be according y large in cross section, that is to say thesemust be very thick. The latter requirement in its turn has been found to render it difl'icult for the said current of gas to blow with sufficient force between the electrodes to produce arcs of the required great length, the reason being that the distance of greatest proximity of the diverging electrodes must be very short, a few millimeters for instance, in order that the energy supplied to the electrodes may be able to jump such space automatically. i My present invention allows the electrodes to be dimensioned as thick as may be requisite or desirable in. view of the energy-to l a strong current of gas.

To such and my invention consists, broadly, in dimensioning the space of greatest proximity of the electrodes so that the current of Specification of Letters Patent.

lowed .to pass through it freely, that is, without the electrodes intervening in its path, and in providing means for starting the discharges, which would not take place otherwise on account of'the distance of greatest proximity of the electrodes being too'large in this way.

The accompanying drawing shows two a, a are a pair of stationary diverging eleo.

trodes, and e is a pipe designed to blow a strong current of gas through the space of greatest proximity of. the electrodes and in the direction of divergence thereof, as indicated by the arrow. Either of the electrodes a has a erforation f in which an auxiliary 'electro e b'is adapted to slide. .The electrodes 6 are thus eletrically connected with'the electrodes (1. Either of them has a suitable handle or the like at from which it is insulated by an intermediate piece 0. The arrangement is such that the distance, between the points of the auxiliary electrodes can be adiusted at will.

While the electrodes (1 may be as broad as requisite or desirable inview of the energy to be received by them, the electrodes 1), whose points necessarily intervenein the,path of the current of gas leaving the pipe c, must be so shaped that they offer the least possible resistance to the passage 0 this gascurrent. To such end it will be advantageous to make them in the form of blades, as is shown in Figs. 1 and 3, or of rods, aswill appear from Fig. 2.

I The function of the arrangement'described is,briefiy, as follows: The discharges brought about between the auxiliary electrodes 1; by adjusting these according to the energy sulp plied to the electrodes (1 are caused by t e current of gas leaving the pipe 6 to pass over to the diverging electrodes a and are blown along the latter so as to form arcs of great leng hs; after having attained a definite length such arcs break and extinguish. Some of t e variations the discharges undergo in this Way are approximately indicated by dotted lines in the drawing.

In order tofacilitate the passing over of liO gas, blown through such space, may be alrods, which constitute the minor details may greatest proximity of the electrodes and in the direction of divergence thereof, the said space being large enough not to disturb a free passage of'the said gas current, and a the discharges to the electrodes 0, the auxil iary-elcctrodes b may, in the case of the form of construction shown in Figs. 1 and 2, be beveled at their points, in the manner re resented; with the ig. 3 the same object electrodes and extendis obtained by the nected to the'former the auxiliary elec-" ing into the space stantially as specified.
