2 Sheets-Sheet 2 GEORGES H-BOUGON INVENTOR ATTORNEY Patented May 24, 1932 UNITED STATES GEORGES H. IBO'UGON, OF SAN FRANCISCO, CALIFORNIA MAGNETIC DEVICE Application filed January 19. 1931. Serial No. 509,736.

My present invention relates to a magnetic device and more particularly to a magnetic device wherein a plurality of individual magnets are disposed in a novel manner to influence a movable member of magnetic material and effect a movement thereof.

The object of my invention is to provide a novel type of apparatus for employing a phe nomenon which I have discovered exists when a plurality of ma ets are disposed in staggared relation wit respect to each other and adjacent a freely movable member of magnetic material.

My invention accordingly consists in the features of construction, combination of parts, and in the unique relation of the various members and the relative proportioning and dispositioning thereof, all as more clearly outlined herein.

To enable others skilled in the art to fully com rehend the underlying features thereof and in order that they may embody the same by numerous modifications in structure and relation contemplated by this invention, I

have repared drawings depicting the preferre forms which are annexed as part of this disclosure and in such drawings like characters of reference indicate corresponding parts throughout all the views, of

which- Fi re 1 is a perspective view showing the sim est form 0 m invention,

Figure 2 is a mo ified form of the arrangement illustrated in Figure 1,

Figure 3 is an enlarged sectional view taken along line III-III of Figure 2 looking in the direction of arrows,

Figure 4 is a plan view of another modification of the arrangement illustrated in Figure 1 in which electromagnets instead of permanent are used, and

Figure 5 is a perspective view illustrating the relative positions of the magnets of each row with respect to each other.

In describing my invention I shall proceed by first discussing the simplest embodiment thereof as illustrated in Figure 1 and then proceed with the further em odiments in the order arranged in the drawings.

In Figure 1 of the drawings there 1s shown two rows of permanent magnets 10. The upper row of magnets 10 is shown as laid upon a sheet of glass or other non-magnetic materail 11 which is spaced from a similar piece of glass or other material 12 by means of suitable spacing blocks 13 and the lower row of magnets 10 is shown as disposed against the lower surface of the glass 12. Each of the magnets 10 is arranged as illustrated with its poles contacting with the back of the next adjacent magnet. It will be noted that the magnets 10 are all arranged as designated with their corresponding poles all in the same relative positions. In other words, they are all disposed in the same positions with respect to their olarity. As here illustrated the sheets of glass 11 and 12 are spaced suificiently far apart to permit a member 14 of magnetic material to move freely therebetween. In this illustration the member 14 is shown as a c linder which may roll to the right between t e sheets 11 and 12 as magnetic forces are exerted thereupon by the magnets.

In Figure 2, instead of the sheets 11 and 12, I show a tubular member 15 of glass or other non-magnetic material through which a sphere or ball 16 of magnetic material may be freely rojected by the forces exerted thereupon y the magnets 10. In this inso stance the magnets are arranged in a manner similar to that described in connection with Figure 1.

By referring to Figure 3 it will be seen that the magnets 10 are cut away at their back portions so that they may be easily disposed about the tubular member 15.

W'hile I have disclosed and described my invention as comprising a plurality of permanent magnets I desire to have it understood that I may use electromagnets. Such an arrangement is illustrated in Figure 4 of the drawings wherein the numeral 37 designates a suitable spool winding which is adapted to be placed upon a core member 38. Extending along and connecting the ends of the core members 38, I show magnetic bars 39 and 40 which are adapted to form pole pieces for the electromagnets 37. In order that the structure here illustrated may more nearly correspond to the arrangement described above I may notch the members 39 and 40 as at 41 and 42 and thus definitely control the direction of the magnetic flux and the movement of an armature thereover as will be understood in connection with the description of operation to follow.

In order to facilitate a description of the operation of my invention I have illustrated in Figure 5 only two of the magnets which go to make up the more complex magnetic fields referred to above. In this description when I refer to a number of magnets in a line, unless otherwise specifically pointed out, it is to be understood that I refer to the arrangement shown in Figure 1.

By referring now to Figure 5 it will be seen that the upper magnet which I shall here designate by the letter A is advanced to the right so that it is disposed substantially centrally over the poles of the lower magnet, designated by the letter B. The magnet A is also disposed directly above the magnet B and the poles of the two magnets and all the magnets of the devices described are laid in the same direction with respect to polarity. Disposed between the ma ets A and B, I show an armature C which is ada ted to move between the magnets. In this escription it will be assumed that the armature is adapted to roll over a suitable support midway between the magnets A and B. It is to be here understood that this armature may be supported in any suitable manner and need not necessarily roll on its support.

As far as I have been able to determine the individual magnets, whenarranged as described, first exert an attracting and then a repelling force upon the moving magnetic member C.

I shall now describe what I believe to be the action which takes place during the travel of the armature over the magnets A and B. It is to be understood that a similar action takes place throughout a complete row of en the armature C is in the position 11- lustrated a certain amount of the flux circulating through the magnet B between the south and north poles will be shunted through the armature G in the direction of the arrow. This will cause the armature C to be attracted by these latter poles, however, as it continues to approach the poles of the magnet B it will retain a certain amount of residual magnetism which will tend to constitute the near end of the armature a north pole. Consequently when the movement and mass of the armature O is suflicient to carry it only a slight distance beyond the end of the poles of the magnet B it will then be repelled by these poles and influenced so as to be moved into a position where it will form a shunt path for some of the flux of the magnet A and become attracted thereby, as was the case with the magnet B.

As the armature C continues in-motion it will come under the attracting influence of the poles of the magnet A and will be moved, as suggested above with respect to this latter magnet, in the same manner as in the case of the ma net B. If it is assumed that there are a num er of magnets A and B arran ed in two parallel spaced lines as illustrate in Figure 1 it will be understood that the armature C will continue to move between the lines of magnets as each adjacent pair operates thereupon as above.

While I have, for the sake of clearness and in order to disclose my invention so that the same can be readil understood, described and illustrated specific devices and arrangements, I desire to have it understood that this invention is not limited to the specific means disclosed but may be embodied in other ways that will suggest themselves, in view of this broad disclosure, to persons skilled in the art. It is believed that this invention is broadly new and it is desired to claim it as such so that all such changes as come within the scope of the appended claims are to be considered as part of this invention.
