ELECTRICAL TOY.

Specification of Letters Patent.

Patented Apr. 24. 1917.

Application filed December 14, 1915. Serial No. 66,757.

To all whom it may concern:

Be, it known that I, GALE S. ELLIOTT, a

citizen of the United States, residing at for its purpose.

Another peculiar feature of this invention is the manner of construction of-the make and break contacts which is used in motors of this character. X I P A still further object of this invention is the arrangement of the reversing mechanism, whereby the rotor may be controlled to move in the desired direction.

These and other objects will present themselves to those skilled in the art, after carefully reading the following specification, in connection with the accompanying drawings, in which, similar letters ofreference indicate like parts.

In the drawings, Figure 1 is afront elevation, Fig. '2 is a sectional view on line 22 Fig. 1 looking in the direction of the arrow,

and Fig. 3 is a diagrammatic view illustrat-- ing the circuit connections.

Supported upon a, suitable base or block 5, are two iron cores 6 and 7 which are connected by another soft iron piece 8, thereby forming a U shaped magnet. Around the cores 6 and 7 there is provided a few'turns of copper wire to form ' electromagnets 8 and 9.

A frame 10 provided with circular openings 11 and 12, is suitably supported on the upper ends of the respective cores 6 and 7 and held thereon by set screws 13 andl l. The end portions of the frame 10 are bent upwardly as shown at 15 and 16.

Near the upper extremity of the arm 15, there is provided a screw threaded opening 17 which is adapted toreceive a screw 18. This screw 18 is held in its adjusted position by a lock nut as shown at 19. The opposite arm 16 is provided near its upper end with a V shaped bearing hole, as is likewise the inner end of the adjustable screw 18.

- An axle 20 having pointed end portions 21 and 22, is suitably supported in the V shaped bearings just described, and itwill be understood that tension of the axle 20 can be adjusted to suit the desires of the operator, by merely adjusting the screw 18.

Keyed to and adapted to rotate with the axle 20 are two spaced metallic members, each of whichis provided with a plurality of arms as illustrated at 23, 24, 25 and 26. Connecting the respective arms of the metallic members are four iron pieces 27, 28, 29

' and 30 thereby forming a simple, cheap yet very efficient armature or rotor.

Heretofore, commutators used in connectlon wlth motors of the character under consideration have been very delicate, intricate or either expensive constructions, and it is my purpose to provide one which obviates all of the above mentioned objections, yet performs its function with just the same amount of accuracy as has heretofore been known.

From each of the arms 23, 24, 25 and 26 of one of the metallic members, there is punched and-bent outwardly at right angles thereto, a tongue, as shown at 31, 32, 33 and 34. Keyed to and rotating with the axle 20 and located between the tongues is a fiber ring 35.

I also provide a very simple construction by which the direction of rotation of the armature may be controlled. A stud 36 is suitably mounted in the arm 15, but is insulated therefrom, by mica or fiber washers, as shown at 37. A block of metal such as is illustrated at 38, is pivotally mounted on the stud 36 and is held in desired adjusted position by means of a set screw 39. Two metallic brushes 4:0 and 41 are fastened to the block 38 and are so arranged so that when the block is tilted, either to the right or left, one or the other brush is in operative relation to the metallic tongues on the fiber ring, so that the armature is rotated either the same, such as Christmas garden decorations.

The circuit may be traced through the toy motor as follows, from binding post 43, wire 44, magnets 8 and 9, Wire 4:5, stud 36 and brushes 40 and ll: The other binding post 46 is connected by wire 47 to the axle 20, and the circuit is completed through the metallic member having the tongues. v

The operation of the motor will be explained as follows, reference being had to Fig. 2, the brush 40 being in contact with the tongue 31, thereby closing the circuit, there will'be then a magnetic field and the nearest piece, 27 of the armature, will be attracted. As the piece nears the cores 6 and 7' the circuit will be broken, owing to the fact that the tongue has left the brush and the latter now rests against the fiber ring. .It will be noted that the circuit is broken just before the armature or rotor is in its deepest position and therefore it will continue to rotate under its own momentum until the succeedelectromagnets and the rotating armature consisting of tongues bent from the metallic frame and a fiber ring arranged within the tongues, and a brush operatively associated therewith.

In testimony whereof I affix my signature in presence of two witnesses.
