SPECIFICATION forming part of Letters Patent No. 777,991, dated December 20,1904.

I 4 Application flied August 29, 1904:. Serial No. 222,660. i

To all whom it may concern: I

Be it known that l, Eauns'r E. Weanna, a citizen of theUnited States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Devices for Projecting Air Against Electric Discharges, of which the following is a speci fication.

M y invention relates to apparatus employed in generating gases from air by the action of e-lectricat discharges; and its object is improvement of the devices for injecting air under pressure into the path of the discharge.

My present improvement consists, essentially, in providing on the end of .the air-induction pipe of the apparatus a rose or cap or equivalent device arranged adjacent to the gap between the terminals and having a number of small openings for discharging compressed air into the gap for the purpose of more effectively deflecting and spreading and spraying or disintegrating the are or discharge, whereby the air is brought into more intimate contact with and is more effectively acted upon by the electric discharge. Furthermore, by means of such device the cooling effect of-the expanding air can be better utilized in keeping down the temperature of the terminals than when but a single air-jet is employed.

In order that my improvementmay be fully understood,I have shown in outline and in part diagrammatically apparatus of the character referred to and a practical form of specificdevice i'or introducing the air to the are.

In such drawings, Figural shows an apparatus equipped with my improvement and adapted to carry out the plan of my invention. Fig. 2 shows the pair of terminals and indicates approximately the normal course of the electric discharge'between them when not subjected to lateral air-pressure. Fig. 3- shows in front elevation the devices of the improvement detached and approximately a'form of the discharge when it is subjected to the action of the alrets. Fig. 4 shows the same parts as Fig. 3 viewed from either side, and

tration, by means of a battery 7.

air-injecting device.

In the drawlngs, 1 indicates a casing melosing' an air-tight chamber 2 and having an in nals are connected to the ends of the seconds ary 5 of a transformer. The primary 6 of the transformer is supplied with current from any suitable source of electric energyas. for illus- The transformer may be of any suitable form, and in practice 1 preferably use the form commonly known as an induction-coil.

For supplying air under pressure to the are formed between the terminals a supply-pipe I Fig. 5 isa top view of the terminals and the 8, which enters through the bottom 3, is ar-' ranged with its discharging end adjacent to and preferably below the ends of the terminals. The pipe 8 leads from a supply-tank 9, in which the air to be subjected to the action of the discharge is contained under pressure, preferably from twenty to fifty pounds. A discharge-pipe 1,0 is connected to the top of the chamber for conducting away the trcated air, and a valve 11 in the pipe 8 enables the passage of air through thepipe to the arc to be contr olledk When this valve is closed, the

course of the are or discharge between the tcrminals will be normal anthpractically direct, andits visible form will be about as indicated by the group'of broken lines 12. (See Fig.2.)

To effectually divert the course of the are or discharge and spread its body or at least its visible portions, I provide asuitable number of small openings 13 in a rose or cap 14 on the end of the inlet-pipe'S and arrange the rose preferably below and close enough to the extremities of the terminals to cause the airjets to be projected against the arc and some of them to be pro ected agalnst or very near to the terminals, as indlcated by the arrows a.

By this means the are or discharge is deflected and elongated laterally and is spread or sprayed somewhat, and the air being free to expand in the body .of the discharge tendsto further spread and disintegrate it, and the air is thus subjected to a maximum degree 'of electrical action, and the cooling effect of the expansion of the compressed air is highly beneficial in reducing the temperature of the terminals and the gases contained in the chamher 2. i

The form of the'visible'arc or when thus acted upon by the air pressure'and expansion is approximately as indicated by the groups of broken lines 15 in Figs. '1, 3,. and 4. 1

Having described my invention, What I claim, and desire to secure by Letters Patent, v n

1. In an apparatus for generating gases from air, the combination with electric terminals, of a device for in ecting a plurality of discharge I jets of compressed air into the gap between the terminals.

2. In an apparatus for generating gases from air, the combination with electric terminals, of a device for projecting compressed air in divided streams against the side of the arc.

3. In an apparatus for generating gases from air the combination with electric terminals, of a device for projecting compressed air in divided streams against the side of the arc and against the terminals.

In testimony whereof I'have signed my name to this specification, in the presence of two subscribing witnesses, this 22d day of August, 1904:.
