INFLUENCE ELECTRICAL MACHINE.

Application filed June 28, 1921. Serial No. 481,131.

is a full, clear, and exact specification.

This invention relates to influence clectrical mach nes adapted to collect and utillze atmospheric electricity, andhas for its obect to provide an miproved form of influence machine of this character whereby electricity for use in therapeutic treatment and other purposes may be readily and efliciently obtained.

The improved machine of the invention comprises the usual pair of insulating discs arranged to rotate in opposite directions and provided with conducting sectors carried thereby, one of said discs serving to exert an influence effect upon the other.

According to the present invention, the

disc which is subjected to said influence effeet is arranged to be supplied with atmospheric electricity either directly ,or indirectly and also by means of one or more aerial antennae through numerous salient poles consisting for instance of spherical conductors and brushes, distributed over the circumference of the disc, connected with the induced sectors thereof and arranged to rotate in the air and closely adjacent to the antennae. By this arrangement a particularly favorable flow of electricity is produced,a rapid excitation of the machine and an efficient collection of the electricity.

The invention is illustrated in the accompanying drawings which illustrate diagrammatically by way of example a form of construction of the improved influence machine.

. Figure 1 is a view in elevation of the complete machine constructed in accordance with one form of the invention.

Fig. 2 being a sectional view of a portion thereof.

Figure 3 is a front view of the portion shown in Figure 2. v

Referring now to the drawings it will be seen that the machine comprises a pair of vulcanite or ebonite discs 2, 3 pivotally mounted upon a shaft 1, and arranged to be rapidly rotated in opposite directions by means of open and crossed driving belts, 5, 6.

On one face of thedisc 2 a number of strips or sectors 7 of tin-foil are secured at a short distancefrom the edge of the disc, the

sectors 7 being completely insulated and adapted to be engaged by two brushes 8 durmg the rotation of the disc 2. The brushes 8 are electrically connected together, but are otherwise well insulated by the insulating support 9.

"The other disc 3 face thereof with strips or sectors 10 of tinfoil as shown in Figures 2 and 3. The sectors 10, however, unlike the sectors 7 on the disc 2, extend to the edge of the disc 3, and are each electrically connected with a spherical pole '11, the poles 11 being arranged around the edge of the disc 3, and forming receiving conductors for the atmospheric electricity. The poles 11 are provided with bunch-like metallic brushes 12 projecting outwards from the disc 3, as clearly shown in the drawings, so as to whip the air when being rotated.

The brushes 12 during the rotation of the disc 3 engage with a number of spherical conductors 14,15, 16 and 17 insulated from one another and mounted upon standards 13.

I The conductor 14 is metallically connected with a spherical conductor 18 and the con-t ductor 15 with a spherical conductor 19. The conductors 16 and 17 are electrically connected by a conductor 20.

Two additional spherical conductors 21, 22, similarlyinsulated upon standards 13 are providedand are so disposed as to be closely adjacent to the path of the brushes 12, without being engaged by the brushes 12 during the rotation of the disc The conductor 21 is electrically connected by a conductor 23 with an aerial antennae 24 extending as high as possible in the air and well insulated from the ground, the conductor 21 forming the pole of the antennae. The conductor 22 is electrically connected by a conductor 25 with a similarly constructed antennae 26 of which the conductor 22 forms the pole. The antennae 241 and 26 may be mounted on separate frameworks side by side with one another or on the same framework one above the other, andseparated by a suitable interval.

I The conductor 25 is connected through a branch conductor 28 from the point 27 to one plate 29 of a condenser, the other plate 31 of.

23 is connected through a branch circuit 3 1 is also provided on one from the point to the inner coating of a lLeyden jar 36 or other suitable condenser, the outer coating of which is earthed by the conductor 35. The inner and outer coatings of the Leyden jar 36 and the plates 29, 31 of th e condenser are provided with spark gaps as indicated at 02, so that large quantities of electricity due, for instance, to lightning striking the antennae, are conducted directly to earth without injuring the machine or interfering with its operation.

Two spherical conductors 38, 39 also mounted on the standards 18 adjacent to the conductors 18, 19 constitute the terminals of the high tensionwinding of a transformer 37 by means of which the atmospheric electricity which is frequently at an unmeasurable high tension is transformed to a lower tension and higher current strength.

For machines of large dimensions the sectors 7 and 10 instead of being made of tinfoil can beconstructed of thin sheet copper, and the discs 2 and 3 may be of vulcanite or ebonite only at their outer periphery, the central portions being composed of wood or cast iron.

The improvedinfluence machine operates in the following manner z- As the disc 2 is rotated the friction of the brushes 8 on the v'ulcanite or ebonite disc 2 generates frictional electricity which is collected on the sectors 7 and is distributed or exchanged by the metallic connecting circuit. All the sectors 7 are thus become charged with frictional electricity, and by their inductive action develop similar amounts of electricity of opposite polarity on the sectors 10 of the disc 8. These induced charges of electricity are obtained from the atmosphere by the rotating end poles 11, 1.2 of the disc 3 and are proportional to the amounts of frictional electricity on the sectors 7. This collection of electricity from the atmosphere is effected firstly in a direct manner by the rotating brushes 12 passing through the air and collecting the requisite amount of electricity and secondly in an indirect manner by the brushes 12 a iiproaching the conductors 21, 22 and thence drawing the required electricity from the antennae and the condenser devices 29, 31 and 36. As the frictional elec tricity on the disc 2 cannot flow to earth, the electric charge on this disc is continually increasing, and causes an equally increasing quantity of electricity to be developed on the disc The conductors 11 serve as carriers of charges of the electricity, until these are given off as the brushes 12 engage with the conductors 14 and 15. The induced charges of. electricity are transferred or exchanged by the conductors 16 and 17 as these are engaged by the brushes 12.

The electricity collected in the conductors ll and 15 passes to the conductors 18 and 19, and sparks. across. to the balls 38, 39 from which the extremely high tension alternating current passes through the high tension coil of the transformer 37 and produces in the low tension transformer winding an opposite induction current, which can be practi rally utilized.

If the charges of electricity from the alays strongly charged earth be opposed in the two condenser devices to atmospheric electricity. the completely insulated antennae become equally strongly but oppositely charged. On the other hand, when large amounts of atmospheric electricity are present due for instance to storm clouds, similar quantities of electricity of opposite sign are bound in the condenser devices. In these circumstances the action of the brushes 12 causes the electricity in the atmosphere to be drawn off the conductor 21 for one antenna and out of the conductor 22 for the other antenna and utilized.

If the electric potential between the earth and the air is too great so as to be liable to injure the machine, the electric tension will equalize at the adjustable spark gaps in and pass to the earth. During a storm, for in stance, it is found that the machine operates as quietly and efficiently as with a cloudless sky.

Beyond the friction of the disc shaft 1. the only friction involved is that due to the contact of the very resilient brushes 12 with the four conductors 14, 15, 16 and 17, so that the machine can be maintained in operation with a very small expenditure of power.

In place of constituting the condenser devices as at :2: also as lightning arresters, special lightning arresters may be provided beside these condenser devices.
