ARC LAM'P.
SPECIFICATION forming part of Letters Patent No. 428,008, dated May 13, 1890.
Application filed January 11, 1890- Serial No. 336,651. (No model.)
1"0 aZZ whom is may concern.-
Be it known that I, PHILIP LANGE, a citizen of the United States, residing in Pittsburg, in the county of Allegheny and State of Penn- 5 sylvania, have invented certain new and useful Improvements in Apparatus for Prod ucing Light by Electricity, (Case No. 381,) of which the following is a specification.
The invention relates to a method of proto ducinglight by the consumption of electrodes by electric currents, and to certain improve ments in the construction of apparatus employed therefor.
The object of the invention is to provide an arc lamp which is simple in construction, efficient and reliable in its operation, which will burn a longer time without requiring attention than the are lamps now commonly in use, and which may be operated by electric 2o currents rapidly alternating in direction. The lamp may be used in connection with continuous electric currents also; but it is especially designed for alternating currents. The invention involves a new method of operation, as well as improvements in the construction and organization of the parts, all of which will be particularly described in connection with the accompanying drawings. In the drawings, Figure]. is a side elevation 3 of the working portion of the lamp. Fig. 2 is a reverse View. Fig. 3 is a diagram showing the circuits.
Referring to the figures, A represents a frame for holding the various parts of the feeding and controlling mechanism. The electrodes are represented atA and A They are shown as being broad and fiat, presenting extended edges to each other, and during the operation of the lamp the arc travels along 4 their edges from side to side. 3y constructing the lamp to be operated by alternating currents certain advantages are secured, which will be set forth in connection with the operation of the lamp. The lower electrode A is held in a suitable clamp carried upon the arms 1), which extend downward from a bracket (1, which is insulated from the frame A. The upper electrode is carried in a clamp B at the end of a rod C, provided 5 with a rack c. This rod is allowed to feed forward under the influence of its own weight and that of the electrode, its movement-s being controlled by a clock-train D. The rod passes through the openings 0 in the frame, and is held in position by a guide-wheel c The rod may with advantage be of rectangular cross-section, the openings c corresponding in shape, and the rack c is then formed along one corner of the rod. The rack is engaged by apinion 0 upon an arbor c. A scape-wheel F is mounted on the arbor c, and an escapement-anchorf is employed for releasing the scape-wheel and allowing it to turn gradually, so that the rod may feed forward. The escapement-auchoris carried upon 6 5 an arbor f", which also carries a vibrating brake-surface For convenience and delicacy of construction this is in the form of a balance-wheel. A brake f is employed for controlling the vibrations of this brake or balance-wheel f hen the brake rests upon the wheel f the escapement is prevented from vibrating, and therefore the rod G is held by the pinion. \Vhen, however, the brake is lifted from the wheel, then the escapement is allowed to vibrate, thus permitting the rod to gradually fall.
For the purpose of releasing the brakewhecl at the proper moments, the entire escapement, including the brake, is carried in a movable frame II, which is suspended by pivot-s 7L from a pivoted beam or frame K. The pivoted frame K is supported from the lamp-frame A by pivots 7:, and its position is determined by means of electro-magnets or solenoids M, M and M. These are provided with movable cores a and n, suspended from the opposite ends of the pivoted frame K. These cores are subdivided for the purpose of adapting the lamp to use with alternating electric ourren ts. They may com-'eniently be made of bundles of wire magnetically separated from each other. \Vhen the core a is drawn downward, the brake is allowed to rest upon the brake-wheel and the rod 0' is held. lVhen the core 'a is drawn into its solenoid, then the brake rests upon a detent m, thus releasing the brake-wheel, which is carried away from the brake. This allows the eseapement to act, allowing the rod 0 to feed IOO forward until the frame K is tilted in the opposite direction. The moving of the frame in the opposite direction also serves to raise the carbon rod, and thus separate the electrodes from each other a sut'licient distance to establish an arc of the proper length, assuming that. they have first been brought into contact with each other. For the purpose of permitting the rod to be raised independently of the action of the escapement, the pinion is coupled to the escapcment-wheel through a ratchet and pawl, as shown at o 0 in a manner well understood.
The system of circuits is illustrated in Fig. The coil M is of fine wire and connected directly across the terminals X and Y of the lamp by conductors 2 and 3. The coil M is of thick wire and is connected in series with the electrodes. The coil M is of thick wire and is connected in a normally-o ien shuntcircuit across the electrodes by conductors l, 5, (3, and 7. The connections of this shunt are completed by a spring contact-arm 1, carried by the frame K and caused to strike against the point j when the rod 0 has for any reason failed to feed forward, and the core 12 is drawn still farther into its solenoid by reason of the increased current; forced to traverse it by reason of the high resistance of the arc. \Yhen the carbons are separated such a distance that the arc is too long, sufficient current is forced to traverse the coil M to draw its core a downward. This tilts the frame K in the proper direction to release the brake-wheel and permit the escapemeut to act. I f now the rod 0 feeds forward, the resistance of the arc decreases, decreasing the flow of current through the shunt-coil M, and this permits the coil M to raise the entire cscapemcut-frame and the rod (3 slightly. If the electrodes were first placed in contact with each other, then this movement of the frame would be suflicient to establish an arc of the proper length. After the are has once been established the oscillations of the frame are very slight and usually only sufficient to diminish the pressure of the brake sufticient to allow the rod to be fed forward as required to compensate for the consumption of the electrodes. If, however, the rod fails from any cause to feed when the releasing mechanism is operated, then the coil M is placed in circuit, affording a low-resistance by-path or shunt for the lamp, permitting the current to flow to other lamps in series without encountering abnormal resistance. The core it, upon which the coil acts, is of such length and so placed with reference to the two coils M and M that when the former alone is in circuit the tendency is for the core to be drawn downward in opposition to the action of the solenoid M upon its core a; but when the circuit of the coil M is completed then its tendency is to lift the core a and place it in a neutral position with reference to itself. This insures that the low-resistance shunt-circuit shall remain closed when the lamp is in operation, and at the same time the parts will be held in position to release the red C. \Vhcn the circuit. between the electrodes is again closed, then the action of the coil M upon the core or is sullicicnt to open the circuit of the coil M The pivoted frame K may be provided with a l. alauce-wcight 7t, and screws lu may be employed to nicely adjust its position.
\Vhile the use of flat carbons or OlOCtlOtlt-S presenting extended edges to each other is not new in systems employing currents continuous in direction, it is new, so far as I am aware, to employ such carbons with alternating electric currents, and certain new and useful results follow the employment of tlat carbons with alternating currents. One result of the use of continuous currents with flat carbons is to hollow out or render concave the upper carbon and till it with pits. This causes the arc to be more or less covered and casts a shadow. At the same time the edges of the upper electrode are liable to chip off, causing a flickering and unstcadincss in the light. \Vhen, however, the current is alternating in direction, both the confronting surfaces are worn away into a wedge shape and a steady continuous arc is maintained. This travels steadily to and fro between the con fronting edges of the carbons, and they wear away evenly. The lamp will burn for a much longer time than when constructed with a single carbon rod or even with two carbon rods, and a great saving is made in the cost of trimming or replacing the carbons.
