Be it known that we, WARREN E. Warmers and MARY E. WALTERS, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Indicators and Power Devices Therefor, of which the following is a specification. I

This invention relates to improvements in power driven mechanisms in which a visible, movable part, indicator or the like is ven motion by 'means of a power device which is active for moving the ngovable device or indicator, without the use of gearing or like moving parts or the use of any parts which will produce a noise of any kin It is an object of theinvention to provide a traveling or moving devi o with hidden ower mechanism capable of moving said device without working parts or mechanism.

It is also an object of the invention to provideoa" moving indicator of magnetic or non-magnetic material, and amotor or power device of magnetic character for actuating the same.

tive view done 0 It is a still further object of the invention to provide a mechanism in which magnetic or non-magnetic materials may be moved through the controlled changing polarity of a magnetic mechanism actuated by an alternating current or one in which the current is broken or interrupted. Irithe accompanying part of this specification, elevation of a mechanism embodying the features of the present invention, the casing of the power device being shown in section. Fig. 2 1s a top plan view of the said power device shown in Fi 1. Fig. 3 is a perspecthe plates or leaves employed in the laminated magnet of the power device. Fig. 4 ,is a vertical, sectional central view taken transversely through a movable indicator, and .1 "the support upon which it drawings, forming Figure 1 is a side rests, the power device being shown inend of poles curved t0 elevation. Fig. 5 1s a detail 'view showing a portion of a movable wheel and a power device for actuating the same, having a series fit the periphery of the wheel Fig. 6 is a fragmentary, detail view in elevation of a part of the periphery of arotating wheel such as may be employed in connectlon with this invention.

I The present invention 15 designed to afford means for actuating and turning a movable partor indicator, the power means being usually hidden from view and operating without noise or motion so that t e movable part or indicator would seem to be actuated in a mysterious manner to the observer. A well adapted for use as an advertism me-. dium, the. movable part being employe with its mysterious actuation, to carry said advertising material, and to bring the same to the attention of observers attracted by its pecu- The device is. especially a liar action, and when applied in that. field of usefulness, IS an improvement on the pr or Patent, No. 962,069, issued to Warren E. Walters and Harry S. Fitzgerrell, June 21, 1910. Since the mechanism is especially well adapted for advertisingpu oses, illustrate-mechanism a opted for that purpose, and the invention will now be described, reference being had thereto, In' the'said drawings, 1 indicates a wheel or circular member, 2 a frame or su port therefor, 3 a base upon which the said rame rests, while L indicates a power device within said base, I

The form of indicator usually'construeted with a rim shown in 1 is ortion of the drawings i glass or other non-magnetic material carried 1 I by spokes 5, also preferably of glass or' some non-magnetic material. T e said spokes are I usually made hollow or tubular, able, solid or liquid substances, such instance metallic balls 6, are movably mounted therein. The spokes are carried by an suitable hub portion 7 which is inounte upon ball or other bearings 8 as clearly.

and movas for shown in Fig; 4, the sa d bearing being oar shaft 9. The said ried by an adjustable adjust ng screws 10 shaft is supported upon which are carried by the frame 2. The said, frame 2 preferably rests upon lassor other non-magnetic feet as indicate wheel is provided with any desired means for carrying advertising material or other at '11. The 5 information, such means comprising usually be- I p the rim of the upright position other movable substance as quicksilver 65 shown injigs. land 4 may run beck and feature of the invention and constitutes a power member operating without movable parts and consequently without noise of any kind. The said power device is preferably made up of a laminated-magnet having a central pole 15 and outer poles 16 and 17.

The said magnet is preferably of the laminated type, beingconstructed of a serles of thin metallic plates 18, usually of the shape shown in Fig. 3. In placing the plates together they are generally dipped in a solution of silica or water glass so as to become coated therewith and then applied side upon side as sho-wnin the drawings. A central ventilating or air space 19 is usually provided between the central plates of the magnet as clearly shown in Fig. 2 for preventing the tendencyio heating when in use.

The central pole 15 is surrounded by a coil 20 usually formed of properly insulated wire 21 and wrapped with any suitable 1nsulating material or with oiled silk, The poles 15, 16, and 17 are provided with recesses 22 formed near one side of each poleas shown in Figs. 1 and 2 of the drawings. In this manner small spur poles 23 are provided'at the sides of the main poles and these small poles 23 are surrounded by small coils .24. The coils 24 are preferably made of wires properly insulated andhaving their ends soldered at 25 or otherwise fusibly connected so as to safeguard the power device and prevent its being burned out. In the event of an excessive heating of the mechanism, the fusible connection 25 will be melted-and the other portions-of the power mechanism thus be saved from injury. The laminated magnet is preferably bound together at 26 by any suitable material as for instance a band of copper or simithe sides of lar material.

The ends of the coil 21 are led to any suitable source of electricity and may be connected with a plug of ordinary construction so as to fit into any incandescentlamp socket. In this manner the ordinary'house current employed may be caused to flow through the coil 21, and such current being an alternating current continually changes the polarity of the poles 15, 16 and 17. The small coils 24 act as lagging coils and retard the change of polarity at the poles with the result that the vibration in the current thus set up operates to 'rotate'the wheel 1, the vibrations ofthe current causing the balls 6 to pass the motor in succession as each enters the magnetic field formed by the power device. The peculiar action of the currents set up in the power device will rotate a wheel or other device. a

It will be seen that the motor operates moving parts and that it can idden from view, and may even and sealed up within the supdevice may comprisea magnet 30 having -a number of outside poles 31 and an inside pole 32 which is surrounded by a coil 33 vsimilar t0 the coil 20 heretofore described.

As shown in Fig. 5 the magnet may be made to conform to the peripheralshape of a wheel as 34. The poles of the magnet are all kerfed in their ends as at 35, and lagging pieces or plates 36 are set therein, all of said plates being extended in the same direction and mounted upon the same corresponding corners of the difi'erent poles. In providing the wheel with means which may be acted upon by the currents set up in the motor, the peripheral portion of the said wheel 34 may have embedded therein metallio wires 37 or plates as desired. In this instance the wheel is usually made of opaque material, so that the attractivemember carried by the wheel is not observable. A wheel of this kind may be made to rotate in a horizontal plane or in a vertical plane as desired, within the scope of the invention.

In employing large wheels, it is found of advantage to use an inner metallic tire or band 55 as shown in Figs. 4 and 6, and to place outside the same a second rim or tire 56, usually made of brass or non-magnetic material. The said outer rim is provided with a series of perforations-57, arranged at intervals so that the inner metallic rirn 52 may be subjected at intervals to ,the attraction of the fields of the power device.

It will be observed from the above description that a wheel or disk of comparatively large dimensions may be employed, a good result being obtained by embedding in the periphery of the wheel or connecting therewith in some manner solid or liquid attraction pieces or substances, bars or rims so that themagnetic fields extending from the poles of the magnet, and which are moved to one side by the lagging pieces or coils upon the poles thereof will continuously rotate the said wheel or disk.

It will also be observed that the device is especially well adapted for use with indicators, advertising mechanisms or like placeswhere it is desired to produce motion without any apparent means distinguishable to the usual observer, and without working parts or connections, gears or any noise due thereto.

The size. of the indicator or movable part employed may be varied to suit the 'circum stances to which it is adapted, and may of course be made in any form, configuration or shape desired. The mysticism of the movement of such an indicator may also be increased by the use of non-magnetic material in its formation, and by mounting the device upon a glass plate or mirror upon glass feet or supports so that it is evident to the observer that there are connections employed or other visible means for the transmission of an actuating energy.

The device may be made in portable form and the supporting base ma have the power, mechanism sealed within t e same so as to reserve the same from examination by the inquiring observer. A

It will also be observed that the power device not only operates without gearing, parts or mechanism connecting it with the member or indicator moved, but that the speed of the driven part may be increased or diminished without any intermediate parts and by merely arranging the power device closer to the moving part. The of course be diminished by separating the arts.

The device of the itself admirably to the advertising of various kinds of goods and wares, for it will be readily understood that any mechanism having a movable part may be arranged in a no ordinary electric speed may present invention lends show-window or otherplace, with an unseen power device such as above described, for

turning or moving it. Thus, vehicles may be advertised, sewing machines, their moving parts being operated by a hidden power device.

What is claimed is:

ing a movable member, a power member having a magnet formed with poles projecting therefrom, a coiled conductor surrounding one of said poles for passing a current of electricity about the same, each of said poles having kerfs in their ends near one edge thereof, coils mounted in said kerfs and having fusible connections and means for separating and supporting the movable member from the said power member.

In testimony whereof, we have hereunto set our hands, in presence of two witnesses.
