Specification of Letters Patent; Application fledl ovember 5.1918
To all'whom it may concern:
Be it knownthat I, Onrvnn- F. CONKLIN,
a citizen-of, the 'Uni ted'Sta tes, residing at Anderson, inf the county of Madison and State of Indiana, have invented certain new. and'useful Improvements in Armatures, of which the following is a specification. I
This invention relates to improvements in armatures of electric dynamos ormotors, and more particularly to what are known as double-wound armatures; that is, armatures .which carrydouble windings, each winding adapted for a different purpose and con: nected to a separate commutator.
The armature forming the subject; matter of this invention is one which, is more especially intended for use in connection with dynamos and-motors particularly adapted function it is performing atthe time.
.. gineering would for-use in connection with motor' vehicles for the charging of the battery which furnishes current for lighting purposes and for self-starting, in which the electric machine must beflfcapable of'use'eit-her as {a motor or generator, dependingupon the .Heretofore, it'has been common to equip the armature with two windings, connecting the windings, to separate commutatorsfor difierentpurposes. In these prior constructions, .the commutator: -are -usually' placed 11 n opposite ends of the-armature shaft,
a though in some cases both' commutators have beenplaced upon' the same end of the shaft. In-gconnectiolnwith devices of this character used-in conjunction with motor vehicles fof'lighting and starting purposes,
however,, 'the requirements are'pecuhar m that it is'usually necessary to have a winding of relatively-,small"wire and large number of turns connected to a commutator for furnishingcurrent for charging the batteries, and a winding consisting of butfew turns of wire' of large Jcros's-section 'connected to the other c mmutator adated to carry a largefvolume of, current or the v purpose of operating the machine for starting the engine ofv the vehicle. Good enuire that the heavy winding for startinge en 'ne be connected too. large commutator, w ile the smaller winding could very properly be connected to a, small commutator. When both commutators are placed upon the-same end of.
the armature shaft, it is obvious that the leads of the armature winding which are 1 5 3 'd1scovered..
connected tOa'thQ commutator located far+- thest from the armature,'mu'st pass through the shell of'the's'ub-structure of the com- 'mutator which is located closest to the armature. This has-heretofore been accomplished by the process of first winding the .lower section of the armature and then threading the leads through holes drilled n the sub-structure or shell ofjthe nearest commutator, which commutator must be large enough in diameter to permit these ,leads to pass through its shell. Inthis case,
it is obvious that it is necessary to place the nearest commutator in position upon the armature shaft before the'farthest commutator is connected up This'results in i convenience and unnecessary expense f 1n winding theouter, coils before a test of the. inner winding has been made, necessitating the remove] of the outer winding in case defect in the inner winding should be The object of this-invention is to' provide means by which .the inner winding 'whichin the present case'ispreferably the 'enerator. or small wire winding, can be comp eted, the
leads. put in place. and soldered to their commutator and thus tested .out before the other commutator is placed in position on the shaft and hence-before the second winding is made. a p
In the accompanying drawings,'-Fi gure '1 is a side elevation of an armature embodying my improved construction; .Fig. 2
Patented apnea, 1913.;
is a longitudinal sectionon the line 2+2 of Fi 1. Fig. 3 is a perspective view in detai of what is hereinafter called-thespider.
- In the said drawin 1 represents the ar mature shaft, havingt ereon any well-known form of armature 2. Located on the shaft on one side of the armature is a sleeve or hub 3 of a spider, the arms 3' of which are e ually spaced apart so new provide a'series 0 channels; this spider being placed upon the-shaft with a press-fit or other connection so as to revolve therewith. Secured to.
the shaft, adjacent the spider, on the side thereof opposite the armature, is a commutator 4 of any well-known construction, the diameter. of which is slightlyv less than the diameter of thespider as represented by the outer peripheries of the arms, this commutator being what is called the outer commutator; 5 represents the inner windings,
which, after being wound about the armature, are extended through the channels be tween the arms 3 of the spiders and connected to the commutator 4. e
' Located on the arms 3 of the spider, is what is called the inner commutator 6, of any suitable construction, and the .outer windings 7, after being wound about the armature over the inner windings 5, are
connected to this inner commutator.
While we have shown the spider formed separately from the shaft for manufacturing reasons, yet if desired,-this spider might be constructed integrally with the shaft. Also, the ring of the outer commutator might be made a part of the spider, but for "manufacturing reasons is preferably made a support for the inner commutator 6. The
course, that t e spider is installed in 'posit1on upon the armature shaft before the outer commutator is placed thereon. It will thus be seen that the inner winding and I the purpose specified.
outer commutator 4- may be first installed and thoroughly tested out for defects before the outer winding and inner commutator 6 are installed, thus obviating the trouble and expense of disturbing an of the parts than the work already comp eted, in the event that any defect should be discovered in the inner winding,- as would be the case in some of the prior structures heretofore. re ferred to. I v
Having thus described my inventi0n,'I claim 1. In a structure such as described, an armature and its shaft, an outer and an inner winding on said armature, two commuta-- tors, one for each win and a channeled support for one of sai commutators on said shaft between the armature. and the other commutator and adapted to receive.
the leads of the inner winding, saidsupport being formed separate'from' the commutator supported thereby;
2. In a structure such as described, an"
armature and its shaft, an outer and inner winding on said armature, a channeled sup.-
port on said shaft, an outer commutator on winding on said armature, a channeled 3 support on said shaft, an outer commutator I to which thei leads from the inner winding are connected, said leads being extended through said channeled support, an inner commutator located on said channeled sup-- port but formed of a separate piece therefrom, the diameter of said outer commutator being less than the inner bore of said inner commutator, substantially as and for In testimony whereof, I have hereunto set-.my hand this 28th day of October 1912.
