UNITED STATES PATENT- OFFICE.
JAMES E. ISEELEY, or Los ANGELES, CALIFORNIA; AssIGiIoR TO SYUHRONOUS STATIC 00., OF Los, ANGELES, CALIFORNIA, A
CORPORATION OF CALIFORNIA.
' OSCVILLATING-CURRENT LAMP.
- No. sa4,4ee.
Be it known that: I, JAMES SEELEY, a
citizen of the United States, residing at Los Angeles, in the .coun'tyof Los Angeles and State of California, have invented a new and useful Oscillating-Current Lamp, of which the following is a specification.
The.v main .object of this invention is to provide means for produc' rays of definite characterfor exam 1e, v i dlet rays.
A further object 1sto provide means for this purposewhich willbe simple and cheap in construction and safe inoperation.
The accompanying drawings illustrate the I invention.
Figure *1 is a verticallongitudinal section of the lamp. Fig. 2 is a transverse section forming t e side wal or .peripheralcasing of Y the lamp.
4 deslgnates a back member or disk, and 5 a front member or disk, said disks bein arranged, respectively, at back and front the lam and engaging the primary coil, which is A hel inengagement therewith by any suitcentral openin able means, such as tie-bolts 6. The back member 4 may be provided with any suitable .supporting means, here indicated as a rod 7, and the'front member may have a 8 for insertion or attachment of any suitable applicator used in surgical operations or generally for the passage of the rays from the electrodes. Said electrodes may be removably supported in their supporting-standards 9 10, as by means of screws 3, said standards extending inwardly from the peripheral wall of the lamp-that is to say, from the primary coil, the upper standard 10 being insulated from said wall by an insulating-block 11 and the lower standard 9 being connected to the outer end or portion of t e primary coil, being provided, for example, with a screw-threaded portion 9, working in a metal nut or head 12,
secured to the outer turn of the primary coil. The standard 8 has an insulating knob or Specification or Letters Patent. Application filed m iz, 1906. Serial No. 209,320.
- the rear 0 coil 2', and electrodes 3,
the transformer to periodica Patented Oct. so, 1900.
i handle 13 onits outer end for manipulation thereof. 14 designates a fastening-nut.
The primary coil consists of a few turns of comparatively heavy ribbon or strip metal wound in spiral form and engaging in grooves 15 in the front and back plates 5 4.-
such as built-up mica. The electrodes 3 are located ad'acent to one another directly in f the opening 8 of the front plate of the-lam ,so that the ra s issuing from the discharge etween said ezactrodes will pass directly through said ope 22 23 designate binding-posts connecte to the primary coil. The lower electrode 3 is connected di- -rectly to outer end of coil 1, said coil havingaperforation 1 through its windings to ermit of passageof standard 10 for said e ectrodes; The upper electrode 3 is connected by wire 25 to the inner endof coil 2.
20, including primary co' 1 of the amp. The alternations in the supply-circuit operate through 1y char ethe condenser, which discharges throu h t e circuit including the spark-ga an primary coil 1, said c rcuit being of owimpedance, so that the oscillations develo ed therein will be of high frequency and 'of' arge quantit have found that with such high-frequency oscillations the violet rays are developed in large amount without the use of extremel high potential of oscillating current, an the lamp is thereby rendered comp aratively economical and safe in operation.
' that would be dangerous to the operator.
What I claim is 1. A lamp comprising/a primary coil and a secondary coil within the primary coil, a discharge-circuit connected to include the primary and secondary coils 1n series, and electrodes connected in the discharge-circuit and located in the space within the primary coil, the said primary coil forming a peripheral casing for the lamp, and front and ack plate members secured to the primary coil to complete the casing for the lamp, said front light.
2. A lamp comprising back and front plate members, the front plate memberhaving an opening, a primary coil located and supported between said members to form a peripheral wall of the lamp, a secondary coil within the primary coil, said secondary coil being of smaller longitudinal dimensions plate having an opening for passage of within the primar coil and in front' 0 the secondary coil, an electrodes arranged within said space in the rear of the aforesaid openingiin the front plate member, saidelectrodes eing connected to be energized by said coils.
In testimony whereof I have hereunto set my hand, at Los Angeles, California, this 3d day of July, 1905.
