MAGNETIC DISTORTION' MOTOE.

Application filed July 2, 1920. Serial No. 393,623.

To all whom it may concern.-

Be it known that I, Monnrs A. Sorrwanrz,

a citizenof the United States, residing at Los Angeles, inthe county of Los Angeles and State of California, have invented new and useful Improvements in Magnetic Distortion Motors, of which the following is a specification. p y

a This invention is a magnetic distortion motor and has for its object the provision of'means for causingarotation of a motor armature by the torque produced by v'aria-:

tions in the susceptibility and permeability of the armature with relationto a' fixed mag netic field. r l It is a further object of the invention to provide, a construction of this character in which the variations in the susceptibility and permeability of the. armature with relation to its magnetic field are provided by varying the temperature of the armature.

The invention will be readily understood from the following description of the accompanying drawings, in which Figure l is a top plan view, partly broken away, of a motor constructed in accordance with the invention.

Fig. 2 is a side elevation of the motor.

Fig. 3 is a vertical section on the line 33 of Fig. 1. j

Fig. 4 is a plan View of the means employed for varying the temperature of the motor armature.

Fig. 5 is a somewhat diagrammatic illustration of a portion of the motor Fig. .6 is a similar view showing the parts after a variation in the temperature ofthe armature.

In the particular embodiment ofthe in vention as illustrated in the drawings, I show a construction consisting of abase 1 having the rotatable shaft 2 extending upwardly therefrom. A disc 8 surrounds shaft 2 and is spaced beyond base 1 asby means of the supporting armst. An armature is fixed upon shaft 2 above disc3, said armature being shown as comprising non-magnetic sections 6-forming supporting means 'for spaced radially extending plates 7 of magnetic or paramagnetic metal.

A fixed magnetic field is provided for the armature between base 1 and disc 3, said field being shown as comprising pairs of radially spaced pole pieces 9 and 10. The pairs of pole pieces are suitably circumferenagainst the ported by collar 20 the pole pieces of each as clearly shown in Fig. 1, and, each of the,

pole pieces, preferably, consist of'a winding 11 received about a core 12 extending up- 1 wardly to a point just beneath the armature. The lower ends of the cores of a pair of pole pieces 9 and 10 are, preferably, connected by an arm 13 mounted upon base 1. VJhile I haveshown pole pieces constructed as above set forth will be obvious that any other type of pole pieces, such for example as usual permanent horseshoe magnets may be employed instead of the pole pieces 9-10.

Above each of the pairs of pole pieces 910 the disc 3 is cut away as shown at 15 so as to expose the pairs of pole pieces, for an appreciable space at each side of said pairs of pole pieces, to the armature arranged above the disc 3. Jets 16 are arranged beneath the armature so as to discharge same, one of said jets being arranged at each of the openings 15 in such manner as to be shifted circumferentially relative to the armature from one side to the other of the pair of pole pieces at said open- PATENT OFFICE.

jets may extend upwardly from an annular pipe 17 arranged to extend through the spaces between the pole pieces, of the respective pairs. This annular pipe may be supported by a spider 18 having a collar 19 rotatably mounted upon shaft 2 and supfixed upon said shaft. The pipe 1? is connected by a suitable flexible connection 21 to a source of supply for a heat or cold creating element. cold creating element is adapted to be discharged through jets 16 against the armature, and the spider supporting pipe 17 and the jets is arrangedto be circumferentially shifted so as to position thejets atone side or the other of the radial line connecting of the fixed magnets.

The operation of the device will be readily understood by reference to Figs. '5 and 6.

The jets 16 being at one side or the other of j permeability of the metallic strips at that side of the radii connectingthe pole pieces of the fixed magnets with relation to the fixed magnets, so that the normal uniform This heat or magnetic field between the pole pieces, and as shown in dotted lines in Fig. 5, W111 be distorted as snown in dotted lines 111 Flg. 6.

' This distortion of the magnetic field will cause a greater attraction between the arn1ature and the magnetic field at one side or the radii connecting the pole pieces of the magnets than at the other side thereof, and as a result the armature will be rotated in response to said increase of magnetic force.

When it desired to reverse the direction of rotation of the armature it is only necessary to shift jets 16 from one side to the other 01': the radii connecting the pole pieces of the magnets. Power may be taken from shalt 2 rotated by the armature in any suitable manner shov-m as incluuding a pulley El i :tixed upon saic shaft.

Various changes may be made without departing from the spirit of the invention as claimed.

hat is claimed is:

1. A motor comprising an armature havradially disposed temperature varying ma netic elements, field magnets and heating ets oisposed around and below said armature, said field magnets having two poles, and the heating jets being adapted to be passed between said poles.

elements, a stationary member interposed between the magnets and said armature and having slots formed therein to expose the cores of said magnets, and heating jets interposed between the two series of magnets and arranged at intervals to correspond with said slots, said jets being movably sustained to occupy one extreme position in which they are disposed at one side of the of said magnets, and in another extreme position in which they are disposed at the other side of said cores.

In testimony whereof I have signed my name to this specification.
