DANIEL MCFARLAN MOORE, OF NEW YORK, N. Y., ASSIGNOR TO THE MOORE ELECTRICAL COMPANY, OF SAME PLACE.
PHOSPHORESCENT-ELECTRlC-UGHT CONDENSER AND ACCUMULATOR.
SPECIFICATION forming part of Letters Patent No. 548,575, dated October 22, 1895.
Application filed January 24, 1895. Serial No. 536,037- (No model.)
To all whom it may concern:
Be it known that I, DANIEL MCFARLAN MOORE, a citizen of the United States, and a resident of New York, county and State of NewYork, have invented certain new and use* ful Improvements in Phosphorescent-Elec= trio-Light Condensers and Accumulators, (Case No. 16,) of which the following is a specification.
This application forms one of a series relating to the production of phosphorescent electric light on the Moore principle of the disruptive discharge of dynamic currents in mean.
The present invention relates generally to the accumulation of the light thus produced by the action of condensing the electricity, accompanied by the light, upon metallic surfaces, and by the use of insulating media.
The invention relates also to certain modifications of the generic invention.
Figure 1 is an elevation, partly in diagram, illustrating the manner of carrying my invention into effect. Fig. 2 shows means whereby the electricity may be so condensed at a desired point as to produce light Where no light had been before produced without a condenser. Fig. 3 is a view, partly in diagram, of what may be conveniently termed a vacuum converter. Fig. l shows, partly in diagram, what may be called a Leyden-jar lamp or means for storing light. Fig. 5 is a view, partly in section and partly in diagram, of a modification of a part of that which is shown in Fig. i.
In Fig. 1, 1 is an evacuated inclosure in the form of a bulb having a large rounded end covered with a metallic coating 2 and 3,10- cated, respectively, on the inner and outer surfaces and formed of a. metallic paint or tin foil, or any other metallic foil, or of any form of material, as long as it is an electric con ducting coating.
4 is an electric conductor extending from the small end of the bulb and terminating in contact with'the inner coating 2. This condoctor 4 forms an extension from an electric circuit of the generator 5, passing through and including a magnet 6, a spring terminal 7, having an armature within inductive relation of the magnet and located within the evacuated bulb l, the fixed terminal 8, and the conductor 9, which completes the circuit to the generator.
From the construction it will be understood 5 5 that upon the passage of an electric current from the dynamo 5 the current will be rapidly interrupted at the terminals 7 and 8, and in view of pending applications upon a similar class of inventions already filed by me it should be understood that the wire 4 becomes luminous with a comparatively low dynamo and that the whole bulb becomes a light producer and the vacuum is about that which would be produced by an ordinary mechanical air-pump. The outside coating 3 is con nected to earth 10. In view of the glass partition between the two coatings and in view of the electric potential of the wire 4 the electricity and the light effect caused thereby becomes accumulated and increased, especially by having a good earth connection between the coating 3 and the ground 10.
Referring more particularly to Fig. 1' is a glass tube properly exhausted and having 7 5 the vibratory terminals as before, 7 and 8, which in this instance may be included in a circuit, as in Fig. 1, or, as shown in Fig. 2, they may be included in a different circuit from that of the magnet 6. They are shown in form as in a secondary circuit of an induction-coil 6', whose primary is in circuit with the generator 5'. The magnet 6 is alternately magnetized and demagnetized in view of the rotary interrupter 11 in circuit with the magnet 6 in Fig. 2. The conductor 4' is shown as carried from the terminal 7 throughout the length of the tube and inside thereof and then outside in such a manner as to be included in circuit with the secondary coil of the trans- 0 former 6' and with the terminals 7 and 8.
If the circuits are arranged and completed as described, so that the secondary current may pass through the terminals and so that the magnet 6 produces rapid interruptions at 9 5 the terminals 7 and 8, then the light will appear as a brilliant illumination around the whole length of the wire l; or if the currents are not sufficiently strong, or if the tube 1 is too long in proportion to the electrical dimenroe sions of the electrical features, then will light only appear at the two ends of the tube, while it will be dark between the ends; but if one grasps the central part of the tube by his hand, as represented at 12, an immediate pro-' duction of light will appear as radiated-between his fingers and in the neighborhood of his hand within the tube. On taking away the hand the light ceases, but still remains at the ends of the tube. as often as desired. It is thought that the hand represents either an earth connection,
or else a large mass of matter adapted to be-.
come electrified and thereby produce a condensing action, for this same effect is produced by placing near the tube a large mass, and it is produced by actually surrounding and touching the tube with any conductor or semi-conductor having a good or bad earth connection.
In Fig. 3, as in Fig. 1, the evacuated incloswe is represented by 1, and the remaining elements, in so faras they are'shown, areine dicated by the-samereference-numerals, this case the coatings 2 and 3are omitted and the conductor 4 is extended through the Wall of the inclosure and terminated by ametallic ball 13, from which, when the deviceis inoperation, sparks may be obtained, even if the magnet 6 is not a very powerful self-induction device; but, of course, the higher the eleotromotive force in the circuit 9 the greater the sparks which may obtained at the ball 13 by bringing to it a conductoror semi-conductor not similarly electrified. This device may be employed for charging Leyden jars or similar condensers, and for performing the same functions aspossessed by the Ruhmkorff coil or the Holtz frictional machine. manner of modifying this device for the purpose of producing greater static eifectsthan by increasing the electromqtive force in the circuit 9 consists in increasing the length of the wire 4 by coiling it or by doing both things.
In so far as the parts correspond to those shown in Fig. 1 the same areindicated by the:
same numerals in Fig. 4. The conductor 4 is electrically connected by springs 14 to the, As in Fig. 1, it is extended inner coating2. to the wall 2 and terminated by the metallic coating 15, and the coating 3 is connected to theearth 10. 1" is a glass bulb which sur rounds the device, so that an evacuated space may be the location of the ball 13 andthe outer coating 3. the inner surface of the bulb 1", softhat it is opposite at least a portion of the coating3. Between the coatings 15 and 3 are suspeded,;
of accidents, when lights suddenlygo out in. dwelling-houses, and as takes place after a. certain hour of the night, this device will continue to give out light because of the electrical energy stored therein. manner that a storage-battery is a means for This may berepeated The.
The coating 15 is located on.
In the same storing up new chemical compounds for producing electricity, so this maybe called a device for storing light, because it accumulates electricity for producing light. The operation ofthe device after once stored is automatic. The balls 17 are attracted to the coat ing 15 and become charged with a load of electricity of one polarity and of the same polarity as that upon the coating 15. Then the balls, after'being fully charged, are repelled by virtue of the principle that like ,electricities repel and unlike attract, and at the same time they are attracted by the same (principle to the coating 3, where they give up their charge to the earth. They are then again attracted to the-coating15, and so they move back and forth very rapidly, each time producing sparks, which may be said to exist throughout the vacuum, producing brilliant illumination. The balls 17 move very rapidly and veryirregularly, so that the average effectis a practicallycontinuous light, and as the balls are made ofelder-pith they produce no sound, although they vibrate back and forth very rapidly.
In order to keep the light stored until wanted the earth connection at 10 may be completely broken at the same time that the dynamo 5 is cut off. When the light is wanted the earth connection may be made, and the rents of com paratively low potential into electricity of very much higher potential.
At the same time the device falls under the name of an accumulator,.because the ball 13 collects electricity upon its surface in proportion to thesize of the surface, and thesame may be transferred to translating devices which are to be operated by the static electricity.
The opaque coatings 2 and 3 do not cause :the loss, materially, of thel-ight, because the surface of the coating 2 is arranged upon a concave, spherical, or conical surface, and
.therefore'the light is radiatedinto space in a concentric manner. The form of this surface .maybechanged to suit the requirements of the case.
Itis evident that a modification of the invention shown inFig. 4 may consist in having ;the tube'l" communicating with the tube 1,
so-that both may be exhausted together and considered as oneevacuated space. This con struction, omitting the electrical features, is shown in Fig.5, the point of exhaustion and sealing being at 19, the tube 1 being open at the lower end 1 and preferably closed at the opposite each other, an electric conductor connecting the inner coating with the circuit of the terminals, and an electric conductor con-,
nected to ground.
2. A phosphorescent electric light accumu lator, consisting of the combination of an evacuated insulating inclosure, vibratory electric terminals therein, metallic coatings upon portions of the inner and outer surfaces of the insulating material of the iuclosure and opposite each other, and an electric conductor connecting the inner coating with the circuit of the terminals.
3. A vacuum converter consisting of the combination with an evacuated inclosure having separable contacts normally touching each other and included in an electric circuit of an electric conductor extending throughout the evacuated space through the wall of the iuclosure and terminated by a ball or mass of material.
4. A phosphorescent electric light accumulator consisting of the combination of concentric evacuated i-nclosures, the first having inner and outer metallic coatings, and containing vibratory electric contacts within sparking distance of each other, and electrically connected to the inner coating of the first inclosure, which coating is also connected to the inner coating of the second inclosure, and flexibly suspended balls located between the last named coating and the outer coating of the first inclosure.
5. A phosphorescent electric light accumulator, consisting of the combination of an evacuated inclosure, containing a condenser made of an insulating sheet and metallic coatings on opposite sides thereof, vibratory electric contacts normally touching each other and electrically connected to the same coating and carried around the insulating material to points opposite the other coating, and means for intermittently and gradually discharging the condenser Within the vacuum.
6. A phosphorescent electric light accumulator consisting of the combination of an evacuated inclosure containing a condenser made of an insulating sheet, and a metallic coating on opposite sides thereof, a device for charging the condenser with elect icity, and means for slowly discharging the condenser at points within the vacuum,for the purpose as set forth of producing light.
7. A phosphorescent electric light accumulator consisting of the combination of an evacuated tube, separable electric contacts, normally touching each other, located at one end of the tube and having a return wire passing throughout the length of the tube and located in circuit with the secondary coil of a given electric transformer 6, means for causing the terminals to vibrate toand from each other, and a conductor or semi-conduc tor located at or near the tube.
In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 8th day of January, 1895.
