T. DOLS MAGNETIC TOY Filed April 23. 1923 A TTORNE Y Patented Jan. 22, 1924.



Application filed April 23, 1923.

To all whom it may concern Be it known that I, THEODORE DoLs, a citizen of the United States, residing in the city of Hopkins, county of Hennepin,

and State of Minnesota, have invented new and useful Improvements in Magnetic Toys, of which the following is a specific-anon, reference being had to the accompanying drawings.

This invention is in the way of a magnetic toy, and the object of the invention is to provide a device adapted to illustrate in a simple, entertaining and instructive manner the principles of magnetism and of w magnets.

1n the drawings Figure 1 is a perspective view showing the device in use;

Figure 2 is a top view of the magnet; Figure 3 is a bottom view of the magnet, showing the poles;

Figure 4 is a plan view of the armature; Figure 5 is an edge view of the armature. The invention consists of two horse shoe 26 magnets l and 2, placed one over the other, at right an les to each other, and so that their poles and S all fall in a common plane. To accomplish this result, the inner magnet would necessarily be shorter than 30 the outer magnet. The magnets are then securely fastened together with a rivet 3 at their point of intersection. A magnetic armature at is then provided, same being constructed of thin iron or steel and cut with a plurality of pointsor rays 5, opposite pairs of which are magnetized positively and negatively respectively, as indicated at N and S thereon, with one or more neutral rays marked X interposed between. This armature is also formed with a small point 6 on its under side at the exact center.

This point serves as a turning point for the armature.

In use, the armature is placed on a hard as fiat surface such as glass, with the point Serial N0. 633,894.

underneath, and the four-poled magnet is then held or suspended over the armature and with the poles slightly spaced therefrom. Upon then turning the magnet on its vertical axis, the armature will be caused to rotate or spin around on its point in manner similar to a top. In this experiment it will be found, of course, that the N and S poles of the magnet attract the S and N poles of the armature respectively, or-that like poles repulse each other, While unlike poles attract, and it is this principle which causes the armature to spin around. Of course the armature will come to rest finally unless the magnet is turned again and again. This device, therefore, affords an attractive means for imparting and illustrating the principles of magnets.

While I have herein illustrated and described a certain specific manner and method of constructing and assembling the elements of my invention, it is understood that I may vary from the same in minor details, not departing from the spirit of my invention, so as best to construct a practical device for the purpose intended, as defined in the appended claims.

I claim:

1. A device of the kind described, comprising two horse shoe magnets set one within the other and at right angles to each other; and a flat and rayed magnetized armature having a central spinning point on its under side.

2. A device of the kind described, comprising a four-poled magnet having the poles spaced apart in a common plane; and a flat armature having a spinning point centrally located on its under side and having magnetized rays extended radially.
