ELECTRIC-ARC LAIVP.
SPECIFICATION forming' part of Letters Patent No. 655,176, `dated August "7, 419o-Q. i
Application filed Qctobei 20,*10899. Serial No. 734,l68.` (No model.) l I To all whom t may con/echt.-
Be it known that I, JOHANN FRIEDRICH Ack! ERMANN, a citizen of the United States, residing at New York, (B rooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Electric-Arc Lights, of which the following is a full and complete speciication,such as willenable those skilled in the art to which it appertains to make and use the same.
This invention relates to arc-lamps; and the object thereof is to provide a lamp of this class which shall be economical and efficient in use" and which shall be capable of long-continued operation without attention or replenishment of material,and is especially adapted for lighthouse and search-light use.
My invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the several. parts are denoted by reference characters and which represents a side elevation of my improved arc-lamp partly sectioned to display the internal construction of several novel portions thereof.
Referring more particularly to the draw ing, I have shown at 2 the negative pole member and at 3 the positive pole member of my improved arc-lamp, each of which consists of a stick or rod formed of material adapted to conduct a current of electricity, such as very hard carbon or chalk or similar material. The negative member 2 is provided at its upper end with acrater or recess 4, the positive member being pointed at its lower end, as at 5.
The members 2 and 3 may be supported by any suitable means, as by a bracket G, (shown in dotted lines,) provided with a set-screw 7 The positive member 3 is longitudinally chambered, as at 8, and an ejector device 9 ot' any ordinary or suitable construction enters the rear end of the chamber S, said ejector being insulated from the member 3, as shown at l0. From the airblast channel and feed-channel of the ejector extend pipes 1l and 12, respectively, to a compressed-air reservoir or aircompressor (represented at 13) and areservoir for containing pulverized carbon, (represented at 14:.) The reservoir 14: may be provided with an air-inlet, as at 15, to facilitate the feed of the pulverized carbon by action of l "12Uhave the usual valves or cocks,as at and 17, for regulating the operation; 1 The fueLreceptaCIe 14C is normally filled with pulverized fuel (represented atlS) consisting oflgranules orismallparticles of carbonaceous material or other substance capable of combustion when passed within the sphere of iniiuence of an electric arc. Pulverized carbon of the grade used in arc-'lights as generally constructed will be effective for the purpose just stated. I may, however, use magnesium or other powder to obtain color eifects. e
The positive and negative members 3 and 2 are connected in circuit in any suitable manner-for instance, by binding-posts 19 and 20, with which line-wires '21 and 22 are re-` spectively connected. The members 2 and 3 are spaced 4apart sufficiently to forni `an arc between the same, as shown in the drawing, and when they are in circuit it is only necessary to operate the ejector mechanism, so that the air-blast will draw the pulverized fuel 18 from the reservoirl and eject it through the chamber or bore S to the space `between the members 2 and 3, where the electric arc will at once superheat and consume said fuel.
It is manifest that the exact construction and arrangement of the elements of my mproved arc-lamp as above set forth are not essential to the embodiment of my invention; but that I may vary the same widely and still come within the spirit and scope of my im` provements.
By means of my improved arc-lamp adisintegration of the two members 2 and 3is largely avoided. It is manifest that said members may be constructed to last in operation a greater length of time than the present are-light carbons, as the heat of thearc expends itself upon the pulverized fuel, and as the continuous feed of a larger quantity of fuel may be maintained no attention will be required by my improved lamp for considerable time. It is further manifest that all the fuel is made use of in my improved lamp, which produces economy of operation, and the amount of fuel admitted to the zone of the arc may be readily varied by adjustment of the ejector.
Any suitable means of actuating the memthe ejector. The ejector connections 11 and bers 2 and 3 to make, maintain, and break loo j the arc between the same may be employed,
such forming no part of my invention.
Having fully described my invention, l claim as new and desire to secure by Letters 5 Patent- '1. In an arc-lamp, a negative pole memberl and a positive pole member, one of which is recessed at one end and the other pointedat one end and chambered longitudinally, an
-xo ejector communicating with saidv chamber,
a fuel-receptacle arranged to communicate with said ejector, f-a sou-ree of compressed-air g supply communicatingwith said ejector,an`d devices for regulating the feed of the fuel to x5 the ejector, substantially as shown anddescribed. j
2. In an arc-lamp, a negative pole member i and a positive `pole member, one `of which members yis chambered longitudinally, an
2o ejector communicating with saidchambena fuelreceptacle arranged to communicate with said ejector, means communicating With said ejector for forcing' said fuel through 'sai'd A chamber in said pole member, and devices for regulating the feed of 'the fuel to the ejector,
.substantially as shown and described.
through said chamber, and devices for regulatin'g the feed from said fuel-receptacle, s-ubs'tantially as shown and described.
In testimony that I claim theforegoing as n-my invention-I have signed my name, iin presence of the subscribing Witnesses, this' 10th day of October, 1899.' i
