ELECTRIC MOTOR,
SPECIFICATION forming part of Letters Patent No. 747,217, dated December 15, 1903- Application filed March 5,1903. Serial l lo. 146.803. (No model.)
T0 at whom it may concern:
Be it known that I, LEnoY S. PFOUTS, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Electric Motors; and I do here by declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which Figure l is a top view of the vehicle, illustrating the motor placed thereon and showing one side thereof in section. Fig. 2 is a perspective view of the motor, showing the inclosing case broken away, and the arrangement of the vehicle-propelling gear, showing the case broken away. Fig. 3 is a view showing a portion of the vehicle-frame, one of the springs, and illustrating the arrangement of the drive-chain tension-bar, also showing the vehiclepropelling-gear case and a transverse section of'one of the sprocket-wheel shafts. Fig. 4 is a side view of the pivoted gear-casing. Fig. 5 is a detached view of the fieldmagnet skeleton.
The present invention has relation to electric motors especially designed for various kinds of vehicles and transmission-gear especially arranged for the propulsion of vehicles; and it consists in the novel arrangement hereinafter described, and particularly pointed out in the claims.
Similar numerals of reference indicate corresponding parts in all the figures of the drawings.
In the accompanying drawings, 1 represents the vehicle running-gear frame, which may be of any desired construction, inasmuch as the vehicle within itself forms no particular part of the presentinvention so far as its detail construction is concerned.
To the running-gear frame 1 are attached the front and rearward axles 2 and 3 in any convenient and Well-known manner, it being understood that springs, such as 4, may be employed and should be employed.
The outer bearing-frames 5 are preferably bolted to the side bars of the running-gear frame; but this particular construct-ion may be dispensed with, inasmuch as the only object in View is to hold the bearing-frames in fixed relative position with the running-gear.
Between the two outer bearing-frames is located the field-magnet frame 6, which fieldmaguet frame is bolted orotherwise attached to the outer l earing-frames 5, and for the purpose of winding the field-magnet frame 6 it is preferably formed in two pieces and the pieces bolted orotherwise connected together. In the drawings I have illustrated these two sections bolted together; but this construction is simply mechanical.
The energizing-coil 7 is preferably wound upon a spool or bobbin formed of the proper shape and size to produce a coil such as shown in Figs. 1 and 2 and is afterward placed upon the magnet-frame e and magnet-frame bolted or otherwise attached together after the energizing-coil has been properly located upon the magnet-frame.
The armature-shafts 8 are located at right angles to the energizing-coil 7, their outer ends being journaled to the outer bearingframes 5 and their inner ends journaled to the inner bearing-bars 9, which inner bearing-bars are connected to the arms of the field-magnet 6. It will be understood that the inner ends of the armature-shafts 8 should be spaced a sufficient distance apart to provide room for the energizing-coil 7.
The armatures 10, mounted upon the shafts 8, may be of any desired style or kind, inasmuch as the armatures within themselves form no particular part of the present invention.
The commutator 11 may be of the usual construction. To the outer ends of the armat ureshafts 8 are securely attached the gear-wheels 12, which gear-wheels mesh with the gearwheels 13, which gear-wheels are mounted upon the short shafts 14, said shafts being journaled in theswinging cases l5, said swinging cases being suspended, as hereinafterdescribed.
Upon the shafts 14 are mounted the sprocket-wheels 16, which sprocket-wheels are for the purpose of communicating rotary mo tion to the rearward wheels 17 by means of the sprocket wheels 18 and the drivingchains 19.
To the ends of the magnet-frame 6 are attached the castings 5 and upon the outer sides of the castings 5 are located the plates 21,
. which plates are provided with the lugs or extensions 22, which are screw-th readed upon their outer peripheries for the purpose of receiving the screw-threaded collars 23, which screw-threaded collars are located a short distance from the plates 21 and are so located so as to provide room for the inner plate of the swinging gear-case 15, which is supported by the extensions 22.
It will be understood that by supporting the swinging gear-cases upon the extensions 22 and having said extensions concentric with the armature-shafts 8 the gear-wheel 13 together with their short shafts can be moved or swung without disarranging the mesh between the gear-wheels 13 and the gear-wheels mounted upon the armature-shafts 8,by which arrangement I am enabled to regulate the tension of the drive-chains l9, and for the purpose of holding the swinging cases 15 at the desired point of adjustment the rods 24 are provided, which adjusting-rods are formed in sections and the sections connected to gether by the screw-threaded couplings 25, said couplings being so arranged that when they are rotated in one direction they will shorten the adjusting-rods and when rotated in the opposite direction they will lengthen the adjusting-rods, by which arrangement I am enabled to bring the gear-wheels independent of each other to or from the front or back axle 2, it being understood that the rear ends of the adjusting-rods 24 are to be attached to the rear axle 2.
For the purpose of providing a means for assembling or connecting the swinging gearcase 15 and properly mounting the same upon their bearings the case must necessarily be provided with the detachable caps 26 and said caps connected after the different parts are properly assembled.
It will be understood that by locating the energizing-coil '7, or, in other words, the fieldmagnet coil, between the armatures I am enabled to energize the armatures by a single coil or field-magnet, and by so doing the same force is applied to each armature and must necessarily be the same force owing to the fact that all the force for both armatu res is derived from a single source.
By my peculiar construction I am enabled to do away with one field-magnet, or, in other words, I am enabled to construct a motor having two independent armatures with a single energizing-coil, by which arrangement I dispense with an energizing-coil for each armature. It is well understood that it is a very difiicult matter, if not an impossible one, to produce two distinct and separate field-magnets having exactly the same force.
For the purpose of protecting the various parts of the motor from dust and dirt or any other foreign substance the shell 27 is provided, which shell may be attached to the bearing-frames 5 or their equivalents, inasmuch as the only object is to hold the shell 27 in proper relative position in reference to the parts inclosed.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an electric motor for. vehicles the combination of two independent shafts lo cated in axillary alinement with each other, and each shaft driving a wheel of the vehicle, an armature on each of the independent shafts,and asingle field-magnetlocated transversely to the independent armature-shafts, and said magnet acting upon the arn'iatures in unison.
2. In a motor for electric vehicles the combination of two independent shafts located in axillary alinement with each other, and each driving a wheel of the vehicle through intermediate mechanism, two armatures one located upon each of said independent shafts and a field-magnet for said armatu res located at right angles to the two independent shafts having the independent armatures and the two independent armatures located in the path of the magnetic circuit energized from a single field-magnet.
3. In an electric vehicle the combination of two independent shafts which are in line with each other and each of which drives a wheel of the vehicle, an independent armature on each independent shaft, and a fieldmagnet located at right angles to the shafts and the armatures mounted thereon and the two armatures located in the path of the magnetic circuit of the single field-magnet.
a. An electric motor comprising two armatures mounted upon separate shafts which are in line with each other, one exciting-coil arranged at right angles in a vertical plane between the armatures, and the armatures located in the magnetic path of the excitingcoils.
5. In a vehicle the combination of two independentshafts, an armature mounted upon each independent shaft, and a field-magnet located at right angles to said shafts and the armatures driven by the magnetic current emanating from a single field-magnet, gearwheels mounted upon the independent shafts, said gear-wheels meshing with gear-Wheels carried by swinging gear-cases, said gearcases swinging independent of each other, and means for imparting rotary motion to the propelling-wheels of the vehicle.
6. In a vehicle, a motor carried by said vehicle, gear-wheels propelled by the motor and meshing with gear vheels carried by swinging gear-cases, and means for holding the gear-wheel casings in fixed adjustment, substantially as and for the purpose specitied.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
