UNITED STATES MURRAY BACON, OF PHILADELPHIA NOVELTY ELECTRIC COl\ PATENT OFFICE.
ELECTRIC MOTOR.
SPECIFICATION formingpart of Letters Patent No. 294,717, dated March 4, 1884.
Application filed December 10, 1883. (N0 model.)
To aZZ whom it may concern.-
Be it known that I, MURRAY BACON, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented Improvements in Electric Motors, of which the following is a specification.
The object of my invention is to construct a cheap and simple electric motor, intended mainly as a toy for amusement, and this object I attain asmore fully described hereinafter.
In the accompanying drawings, Figure l is a vertical section of the motor. -Fig. 2 is a plan view of the same." Fig. 3 is a perspective view of the casting for the frame, and Fig. at is a view of the commutator.
A is a base, of wood of other non-conducting material, mounted on suitable feet, a, and on this is secured the frame 13, carrying the electro-magnets D D'-two in the present instance-and provided with bearings f f for the axis F of the armature E.
The construction of this frame B will be more readily understood on reference to the perspective view, Fig. 8, of the casting there- This consists of two arched side pieces, I) Z, connected at their ends by cross-pieces I) b, which are to rest on the base, and these cross-pieces are provided with lugs (Z (1, set at such an angle that the axial line of each electro-magnet, when secured thereto, will be on a line radiating from the center of the axis of the armature, asshown in Fig. 1. The upper central portions of the arched side pieces, Z) Z), are preferably flattened to receive the bearing-blocks f f for the axis of the armature E. The latter is provided in the present instance with six pole-pieces, c c, on as many radiating arms or spokes, but the form of the armature and the number of its poles may be varied, the construction preferably being such as shown in the drawings that is, with the poles so arranged in reference to the poles of the electro-magnets D D that when one pole of the armature comes opposite the pole of one of the magnets, D, another pole of the armature will be approaching the pole of the other magnet, D. On the-shaft of the armature is mounted, preferably outside the frame, the commutator G, Fig. 4, which may be of any suitable construction, but with contact-surfaces equal in number to the poles of the armature. To the side frame adjacent, to the commutator is secured theinsulating-block H, carrying the two spring contact fingers or brushes h h, which are so arranged that the contact-surfaces of the commutator will touch first one and then-the other. These brushes may be adjustable, if desired. To the brushes h h are connected terminals 1 2 of the coils D D, while the other terminals, 3 at, of the coils are connected together and to the binding.- post p. The metal frame is in connection,
that when these posts are connected up in an electrical circuit, with the parts in the positions shown in Figs. 1 and 4, the circuit will be from the post 1), through the metal frame, shaft F, commutator G, brush h, and elec- 7o fro-magnet D, to the post 1), while the electro-mag11et D will be out of circuit. The armature being started in the direction of the arrow, Fig. 1, the magnet D will exercise an attractive influence on the approaching pole 7 5 of the armature, while the magnet D will then have no effect-or, owing to induction, a repelling eifect-on the receding pole of the armature until the approaching pole of the armature comes opposite the pole of the magnet D, when the latter will have been cut out of circuit by the commutator and the magnet D thrown in, so that the latter will then have an attractive influence on the pole which the momentum of the armature is moving to- 8 5 ward it, and so on continuously as long as the motor is in circuit.
A double motor may be made by using two frames set opposite each other,- and, if desired, the armature may .be wrapped so as to augment the power of the motor.
I claim as my invention 1. The herein-described frame for electric consisting of the arched side pieces motors,
through the wire 5, with the other post, 1), s0 65 with connecting cross-pieces at their ends, Intestimonywhereof Ihavesignedmy name 10 having inclined lugs, as and for the purpose to this specification. in the presence of two subset forth. scribing witnesses.
2. The combination of the frame, consisting 5 of the arched side pieces, connecting cross- MURRAY BM'JON.
pieces, and inclined lugs, with an armature mounted in bearings on the side pieces, and \Vitnesses: QiGOiJIOIUZIgDGtS secured to said inclined lugs, JOHN E. PARKER, 4 substantially as described. HUBE'RT Henson.
