FRANK E. KINSMAN, OF PLAINFIELD, NEWV JERSEY.
ELECTRIC-LIGHTING SYSTE M.
' SPECIFICATION forming part of Letters Patent N0. 407,895, dated July 30, 1889.
Application filed October 13, 1887. Serial No. 252,220. (No model.)
To all whom, it may concern.-
Be it known that I, FRANK E. KINSMAN, of Plainfield, in the county of Union and State of New Jersey, have invented an Improvement in Electric Lighting, of which the following is a specification.
I-Ieretofore an electric current of high potential has been transmitted through a main conductor and through the primary of a converter at a distance so that the current set up in the secondary of the converter is of lower potential and of greater quantity for actuating electric lights in the secondary circuit. Reference is hereby made to Letters Patent No. 351,589 for a description of a converter of this character. The secondary current set up, as aforesaid, is alternating and adapted to incandescent electric lights; but before my invention an arc-light had not been success fully introduced into the secondary circuit containing or adapted to contain incandescent lights. .If a secondary alternating current, as aforesaid, is passed through the controlling-magnets in an are light, the alternations of the current will render unreliable or impracticable the magnetic regulating mechanism for drawing the are between the carbons and maintaining the proper length or are, because the magnet becomes highly heated and injured or destroyed by the Foucault currents.
By my present improvements I am enabled to employ upper and lower carbons of the same length in an arc lamp, and to regulate the feed of the carbons and the length of the are by the action of a magnet or magnets in the most perfect and reliable manner, and to introduce one or more are lights in multiple are between themain conductors in the secondary or induced circuit.
In carrying out my invention I have made use of an electric lamp corresponding generally to that set forth in Letters Patent No. 330,351, granted November 10, 1885, to Otto Romanze but my invention is not limited to such a lamp, and I have modified the same in the particulars hereinafter named, whereby injurious eifeots from an alternating current are avoided.
In the drawings, Figure 1 is a diagram illustrating the connections between the lamp and the primary and secondary circuits. Fig. 2 is an elevation, in larger size, of the lamp; and Fig. 3 is a separate elevation, and Fig. 4 a plan, of the core. Fig. 5 is an elevation, and Fig. 6 a plan, of the core made of strips of iron.
The core A, through which the upper-carbon holder B usually passes, is suspended by the adjustable spring 0, and the carbonholder 13 has upon it a rack, the teeth of which engage a pinion l), and upon the shaft of this pinion is a wheel E and pulsator F, that regulate the downward feed of the carbon-holder, and there is a detent a, that stops the pulsator when the core A is drawn up into the helix G by the increase of current through the helix and the electric circuit, of which such helix forms a part. The feed mechanism and the construction of the carbonholders may, however, be varied.
I have discovered that when the core A is divided up longitudinally and when such core projects 'below the helix a sufficient distance the helix and core can be made use of in regulating the arc of the lamp when alternating secondary currents pass through the said helix. The soft-iron core is slotted longitudinally either entirely through the core or else the slots do not all extend through the lower end of the core, so as to leave the necessary connections between the parts of the core; but I prefer to employ longitudinal strips of soft iron around a brass, vulcanite, or other non-magnetic tube, and to bind these wires or strips to the tube by a layer of paper or other material wrapped around the said longitudinal strips, so as to form a tubular core that will not become heated by the Foucault currents. The core is to be placed and adjusted so that it will not pass through the helix, but will project at the end thereof suff1- ciently for the varying magnetic attraction due to the greater or less length of the are between the carbons to adjust the carbonholder and draw the are or feed the carbon.
Referring to the diagram, Fig. 1, the primary circuit M M leads to any suitable dynamo or other source of electric energy of high potential and N illustrates the primary of the inductorium or converter, and O the secondary of said converter, the latter being of larger wire than the wire of the primary,
so that the current will be of greater quantity but lower potential than the primary currents.
The wires M Ill from the secondary ol' the converter are to receive between them incandescent lights in multiple are, as illustrated at I, and the are lamps constructed as aloresaid are also introduced between M Ill. in multiple arceither singl y, as at- Q, or with two or more in multiple-arc series, as at (.3 Q, according to the size of the are lamp and the current to which itis adapted and it will be found that when the are lamp is COllStl'tlCllGtl as hereinbctore indicated such. lamp can be used. in multiple are or multiplc-arc series in the secondary circuit of a converter, andv that incandescent lamps can. also be used in the same circuit without :injuriously a [tee ting either the are lamp or the incandescent lamps.
There should be a switch .5 to each lamp. \Vhere the lamps are used in multiple are the same should break the multiple-arc circuit when the lamp is extingiiiished, and when the lamps are used in. series such switch should be a circuitpreserving switch of any known character, so as not to break the mainline circuit when one lamp is extinguished.
It is well known that a secondary currtmt of low potential is not dangerous to persons handling, are lamps; hence the risk of danger is reduced. to a minimum.
The magnetic energy developed inv a solenoid is augmented by the use ol. a slotted core; hence heavier carbons can be used in my improved lamp without any stronger current being required.
The ends of the two carbons will be similar in shape as they are burned, because the currents are alternating, and it there is not sullicient light below the lamp a reflector around the upper part can be made use ol.
l claim as my invention 11. The eoml. inati .m, with the primary and secondary circuits and. the converter there with connected, having a small wire in the primary and a largewire in the ser.:ondary, ol. an arc lamp having a mu'bon-holder, a helix in the secondary circuit, and a tubular core divided longitudinally and projtwting below the helix, and mechanism t'or (.amneta'ing the carbon-liolder and core for regulating the can bon-lmhlers, substantially as set forth.

23. The combination, with the primary and secomlary circuits and the (ainverter therewith eonnectcd, having a small. wire in the primary and a large wire in the smjeondary, olf incandesmznt and are lamps in the sec .n1dary circuit and a helix also in the secondary circuit, andv a core and mechanism acted upon by the same for moving and .reg'ulatin the earlu n-holder ol the arc lamp, substantially as specilied.
