PAT NT DANIEL MOFARLAN MOORE, OF NEW YORK, N. Y.

I ELECTRIC-LIGHTING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 548,128, dated October 15, 1895.

Application filed April 10 18 95. Serial No. 545,168. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL MCFARLAN MOORE, a citizen of the United States, residing at the city, county, and State of New York, have invented an Improvement in Electric Lamps and Circuits for the Same, of which the following is a specification.

The present invention relates to certain improvements in a system of electric lighting disclosed in other pending applications filed by me, but more particularly claimed in my application for patent filed July 19, 1895, Serial No. 556,457, as a continuance of the present application as originally filed. In that system I produce luminous effects in a rarefied receiver or other suitable lightgiving source by the electric disturbances or vibrations set up in a circuit of induction through interruptions of the current flowing thereon effected in a vacuum.

The present invention relates particularly to arrangements whereby a number of lamps may be operated by a single interruptergor series of interrupters common to said lamps and to arrangements of self-induction coils or similar reactive devices whereby the electric waves or disturbances may be reinforced.

The invention consists, further, in a novel form of lamp adapted to be rendered luminous by electric waves or disturbances operating in or upon a receiver containing a rarefied gas or vapor.

In the accompanying drawings, Figure 1 is a diagram illustrating my invention. Fig. 2 shows the invention as carried out with a modification in the form of circuit interrupter. Fig. 3 is a side elevation of the rotary interrupter. Fig. 4 illustrates a modification in the connectionof the apparatus. Fig. 5 shows a simplified arrangement. Fig. 6 shows another modification in the manner of connecting up the devices to produce energy suitable for operating the lamp.

A is the lamp suitably made for operation by electric waves, vibrations, or disturbancesgenerated in a circuit of induction through sudden interruptions of a current flowing through it. In a general way the lamp may tains a rarefied gas or vapor subjected to the action of electricity conveyed inductively or conductively to it to render it luminous. At the same time it is to be understood that my invention may be carried out by the use of any lamp adapted to be rendered luminous by sudden and repeated electric waves, disturbances, or discharges,such as may be developed, as herein described, by repeatedly interrupting a circuit of induction.

The lampAshoWn is a sealed bulb of glass into which circuit-wires 2 and 3 enter and terminate within the bulb, as a ring 5, preferably of aluminum, forming a-terminal of wire 2 and a helix or spiral 6, connected to wire 3. These are electrodes suitable for use when the energy for operating the lamp is developed by interruptions of a continuous current in the circuit of self-induction connected as herein described. When an alternating current is used, the terminals should be similar. v O is any suitable generator of electricity connected with the mains or wires 7 8, and in multiple across said mains are placed inductive resistances indicated by the, letter B, and through which the current from the generator 0 may flow. Each resistance B is formed, preferably, of a helix of self-induction and each constitues a shunt or branch circuit around the terminals of one of the lamps A. It is obvious that anyinterruption of the current flowing over the mains 7 8 and through the helices B will set up in each helix an extra current, which will act upon the circuit of the lamp to which it is connected independently of the other lamp or lamps.

I have before discovered that if the interruptions of the current-flow in the self-inductive helices be made very abrupt and are repeated with sufficient rapidity the electric disturbances or waves of energy generated in the helices-B of self-induction will render the lamps A luminous. These interruptions of the current-flow are preferably made in a vacuum which is as near as possible perfect.

In the diagram Fig. 5 I have illustrated my invention in a simple form. The interrupter of the current from the generator 0 is indicated at H. In Fig. 1 the interrupters are in dicated at F and E. The interrupter is composed, as designated in the latter figure, of a lamps.

vibrator-spring 18, adapted to make and break connection witha contact 19. The parts of theinterrupter are inclosed in a sealed bulb, preferably of glass, which is exhausted The 'intererating said interrupter, I may employaa electromagnet 13", connected to the circuits, as

shown in Fig. 5, so that the interruption of the connection by the magnet pulling down upon the armatureconnected with spring 18 will dc-energize the magnet and allow the spring to return to circuit-closing 'position, the action being in all respects, so far as the movements-of the interrupter areconcerned, the same as those of the well known automatic magnetic vibrator. By iplacing the magnet "B in the position shown,so asto-constitute practically one of the multiple-arc branches across the the circuits 7-8, it-z-i-S dbvious that "the electric *waves,v'ibrations, or disturbances generated by the interruption of the flow of current from generator 0 through magnet B will flow from the flatter in multiple with the *waves or disturbances from eachcoil B, so as to reinforcetheeflfect of the latter oneach lamp.

My invention is not limited to'anytparticular voltage of the: gen erator C, but I havecbtained good results from an ordinary onehundred-and-ten-volt continuous-currentgenerator acting upon the coils B,suitably wound or proportioned as to their resistance and self-induction, so as to give a good reaction and extra current.

In Fig. l 'lhave illustrated the wa-yi-n'which two 'interrupters may act in'conjunction and the wavesor disturbances generated in'their actuating magnets may beconducted inborn-i mon "to the circuits 78*for operation upon the Each interrupterand its mag'netare connected to the circuit'in substantially the same way as thatshown in Fig. 5,as will= be obvious from'inspection of the diagram.

In Fig. 4: I have shown another arrangement'of the vibrator-magnet, and the coiils B in shunt aroundthelam'ps are omitted. 'l he magnet B in Fig. 4,65 in the main circuit, as isobvious, and the waves or disturbances ot sel't induction generated by int'erru-ption'of the'current-flow throughit circulate through the generator 0, to and firom themains 7 and 8,foractionupon the'lamps A.

In the arrangement shown in Fig.6 thecircuit of induction which is *interruptedand which discharges to the lamps is that of the generator alone. Although the magnet B is in the circuit when the current flows, yet it is in such position that upon interruption of thatc'ircuit its path of discharge is broken, leaving the self inducti0n of the generator 0 as the only effective agent for theproduction suitable bearings therein and carrying armatures 't' of an electric motor, the field or actuating magnet of which is the magnet B. The

commutator of said motor consists of the spring 7', engaging with the commutator or interrupter-wheel 0 within the vacuum, said commutator being so arranged that it will close the circuit of the *m'agnetBto 'cause the latterto attract the armatures, but will open the circuit ias't he rarmatures approach the'imagne'tfwhereiipon ithe momentum will bring ithe'commutator around to close circuit and attract the "succeeding armature. The interrupter which-gen erates the wa vesor disturbances for operation on the lamlp consists of the spring riand wheel 0, as will be obvious, theicircuit arrangement being substantialliy the same as thatshown in Fig. *5.

lheielectricail:actiomof the apparatus, Fig. 2, in.generating thewaves 0r =disturbances for action'onthe lamp A is obviouslythe same as already explained.

to employ one such as described,wherein the rotation 'is producedbythe action of an extra magnet the self-induction of which generates the wa'vesor disturbances by which the damp is' operated.

The generation of electric waves or "disturbances by repeated interruptions in a vacuum ofa-circ'uit of inductionin the man nerand by the means herein describedand the employment ofsuch disturban ces to=generate light ina rarefied-gas=or vapor or other equivalent lamp are not herein claimed, as they form the subject of claims in-my application filed July 19, 1895, Serial No. 556,457 as a continuance of the present application.
