ELECTRIC MOTOR.
SPECIFICATION forming part of Letters Patent No. 451,872, dated May 5, 1891.
Application filed June 4,1890. Serial No. 354,213. (No model.)
To all whom it may concern:
Beit known that I, FRANK M. LA BoiTEAUX, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Electric Motors, of which the following is a specification.
My invent-ion relates, primarily, to electric motors for domestic. purposes Which receive io power fromv any Dsource for supplying electricity; but it is also applicable to dynamoelectric machines for furnishing electricity. The invention will be first fully described in connection with the accompanying drawi 5 ings, and will thenbe particularly referred to and pointed out in the'claims. i
Referring to thedrawings, in Which like parts are indicated by similar reference-letters Wherever they occur throughoutthe vazo rious views, Figure l is a rear elevation of a fan-motor vembodying my improvements mounted upon asuitable stand or base to be placed upon the table or other support. Fig. 2 is a side elevation of the upper part of same. Fig. 3 is a plan view, upon an enlarged scale, of the cap of the base or stationary member. Fig. 4 is an inverted plan view of the base which supports `the rotating field and its connections. These views 3 and 4 are taken on 3o the line as' @o of Fig. 1, looking in opposite directions. Fig. 5 is a side elevation of the armature and commutator, their shafts and connections. Fig. 6 is a central longitudinal section of the pole-pieces and yoke of the electro-magnet. Fig. 7 is an end elevation of the armature-core. Fig. 8 is a side elevation of the same. Fig. 9 is alongitudinal section through the spools and a conter piece'mounted upon a spindle to illustrate my improved Fig. 10 is an edge elevation of the separating-piece shown in Fig. 9. Fig. Il is an elevation of the spools after Winding and ready to. be placed in the field. Fig. 12 is a longitudinal section taken through the axis of the shaft,
Fig. 5.
I will first describe my fan-motor as illustrated in Figs. 1 to 4, inclusive, and then describethe separat-e features which are of my oWn invention and which cheapen its construction and enable me to make it more compact and effective than it could be made if one or more of the older devices for the same purpose separately considered were employed in the same position. 5
The core of the field-magnet A A has secured upon its poles a yoke B, the arms of Which terminate in bosses b, which furnish the bearings for the shaft C, which carries the armature D, commutator E, and the fan F. 6o The yoke A of the magnet-core has project ing downwardly from it a short tubular extension a to pass over a small stud-pin g, which is secured in and projects up eccentrically from the top of a cylindrical cap or casing G. This cap G has projecting downwardly from it a pivot-pin g', which has its point turned cone-shaped to rest in a step, which is secured in the top of the base or tiipod II. The tripod is preferably formed of 7o Wrought-metal pipe, which is split up from the bottom and has its split ends turned out- Wardly to form the feet 7L,Which are perforated to receive screws, by which the tripod is secured upon the circular base I or to any support, should it be desirable to dispense with the base and make the motor stationary. There is secured to the top of the tripod a disk J, Fig. 3, of vulcanite fiber or other nonconducting material, which has secured upon 8o its face two metal rings K L. In the top of the casing G is placed a disk M, Fig. 4, which has secured upon its under face tivo spring contact-pieces K L. These are arranged to' bear upon the rings K and L when the motor 8 5 is placed upon its stand, as in Fig. l. The conducting-wires connect the commutatorbrushes m with the contact pieces K L', while the rings K L are connected to the binding post n by the Wires which pass 9c through the tubular tripod II and through the base I, thebottom of the base being recessed to permit the Wires to be connected to the bottom of the binding-posts. The wires from any source of electricity are connected to the binding-posts in the usual manner. It is obvious that the position of the rings K L and brushes K L may be reversed. I have also mounted an incandescent lamp O on top of the yoke B, to be used when desired.
I mount the motor eccentric to the pivotpiii g', thus placing the armature-shaft out- IOO side the axis of the vertical pivot. 'lhe force of air causes the motor to revolve around when the fan is in motion and force the air alternately to all parts of the room. The speed with which the motor revolves around upon its vertical pivot may be regulated by adjusting it around its supporting-pin g by means of the set-screw a. The farther the plane of the armature-shaft is placed from the plane of the vertical axis g the faster the motor will move around its vertical axis, and vice versa.
I have shown my motor provided with only one fan; but two maybe used, one on each end of the shaft, in which case one should be larger than the other.
I will now describe the specific features of my motor.4 The field-magnet I construct of iron tubing. The pole-pieces a2 are flattened and curved to conform to the armature. The yoke Ais an ordinary return-bend, into which the cores AV are screwed after the fieldspools are in place. The field-spools P P are both wound continuously and in the same direction.
Referring to Fig. 9, I place both spools P P upon a mandrel Q., with a separating-piece R between them. Passing the end of the wire through the head of the spool P and startingthe mandrel, I wind to the left until the opposite end of the spool is reached. 'Ihe wire is then passed between the arms of the separating-piece R over to the other spool P', which is wound in the same manner until the opposite end is reached. Then returning, one coil after another is wound upon the spools alternately, crossing between the arms of the separating-piece until the desired amount of wire has been wrapped upon the spools, after which they are removed from the mandrel, the separating-piece R withdrawn, and the spools turned parallel to each other, as seen in Fig. 1l, ready to be secured in place in the field. The core of the armature is made up of iron disks D, preferably stamped out to the form shown in Fig. 7. The end disks are for strength made thicker than the intervening ones and the edges surrounding the perfoi-ations rounded off to prevent injury to the insulation on the wire. The disks have intervening paper washers d of the same shape kas the disks. The wire D is wound around the core into the perforations d through the slots (Z2. By this means the periphery of the core is made to revolve in close proximity to the poles of the magnet and the full in ductive force of the magnet is utilized. The wireis also protected by the overhanging portions of the core, which project beyond it.
In order to readily remove the armature and commutator for repairs or to rewind the armature,I have mounted bot-h armature and commutator upon a tubular sleeve S. The ends of this tube are exteriorly screw-threaded and longitudinally slotted for a short distance back from the ends. The screwthreaded ends of the tube are made slightly tapering, so that when the shaft C, which snugly [its the tube S, is pushed through it and the nuts s tightened the ends of the sleeve will be tightly clamped upon the shaft.
The eommutator-bars have beveled ends and are held in position bythe concave cups e c' in the usual manner. To remove the armature and its connection,it is only necessary to loosen the nuts .S and withdraw the shaft C without disturbing the other parts.
What I claim isl. In an electric motor, the combination of the stationary base, the pivoted cap mounted thereon, the motor eccentrically mounted upon the pivoted cap, and insulated contactpieces, as K K L L', to maintain the circuit between the main and motor wires while the motor revolves upon its base, substantially as shown and described. L
2. The combination, substantially as hereinbefore set forth, ofthe stationarybase having a step to receive the pivot of a revolving cap, the disk J, secured upon said cap, the insulated rings K L, secured upon the disk, the swiveled cap pivoted to turn upon said base, the disk M, secured to the cap, the i11- sulated spring contact-pieces K L, secured to the under side of said disk and having their free ends bearing upon the rings I( L, the field-magnet secured eccentrically upon the pivoted cap, the yoke B b, secured upon the magnet to furnish bearings for the motor-shaft, the shaft journaled in said yoke, the fan secured upon the end of the shaft, the armature, and electrical connections.
3. The combination, substantially as speciiied, in an electric fan-motor, of the motorstand consisting of a stationary base and pivoted cap, the yoke B ZJ, secured upon the magnet to furnish bearings for the motorshaft, the shaft journaled in said yoke, and the fan secured upon the end of the motorshaft.
4. The combination, in an electric fan-motor, of the stationary base and pivoted cap, a pin projecting up eccentrically from said cap, the lieldmagnet having the downwardlyprojecting tubular extension to lit over the eccentric-pin of the cap, and a set-screw to adj ust the magnet around its support to regulate the speed of the motor around its baksepivot, and the armature-shaft and its bearings supported upon the field-magnet, substantially as shown and described.
5. The combination, in a field-magnet, of the core A A', formed of iron tubing and having the poles a2 CL2 flattened and curved, and the tubular, return-bend A, forming the yoke.
