OSBORN P. LOOMIS AND HENRY NV. GOOLEY, OF LYNIZ, MASSACHUSETTS.
REGULATGR FQR DYNAMO=ELECTRiC lVlACHlNE e Application filed Septemberlfl, 1885. Serial No. 177,791.
To aZZ whom, it may concern:
Be it known that we, Osnon-iv P. Looms and HENRY W. CooLnY, citizens of the United States, and residents of Lynn, in the county of Essex and gtate of Massachusetts, have invented certain new and useful Improvements in Regulators for DynamoElectric Generators, of which the following is a specification.
The present invention includes valuable and patentable features having reference to certain important improvements in the form, combination, and disposition of the several elements embodied in the construction and necessary to the operation of the class of devices named in the title of this invention, but which, in conjunction with our improvements, may be devoted by the party controlling the patent to any purpose now or hereafter proposed.
The invention relates more specifically to the regulation of dynamic electric currents, and to that class of regulators employing a variable resistance in a shunt to the armature of the dynamo, said class being the subject matter of a contemporaneous application filed by us, and claiming, broadly, tne introduction into the said shunt of a variable resistance.
By general but critical examination of the state of the art as disclosed by periodicals, books, and the more important patents, it is evident that there is plenty of room for im provement in the class of devices forming the subject-mater of this specification. One device is simple but ineffectual; another is too complicated, and therefore too expensive; another is, from the very nature of its construction, unattractive in appearance and inconvenient of operation, while others are practically worthless a diligent and systematic study in the application of the principles of science and of invention, and by trials of successively improved devices, we have succeeded in eflecting such important improvements that the device is at once adapted to meet the wants of all concerned in a very ehcctual and superior manner, which is the object of ouriuvention.
The object more particularly is to provide a superior automatic device for the purpose of throwing more or less resistance into the shunt to the armature of the dynamov forming part of Letters "Patent No. 337,775, dated March 9, 1886.
(No model.)
The invention consists of certain elements organized, essentially as described, in conformity to the accompanying drawings, adapted to operate as hereinafter explained, including all modifications as to their form, combination, and disposition, applicable to any purpose mentioned or not mentioned, but especially applicable to the uses alluded to, and different, when considered in entirety, from any device ever before made public, as far as the records prove.
Being more specific, the invention consists of a variable resistance located in the shunt to an armature of a dynamo and operated by mechanism embracing a motor and a solenoid, both located in the circuit of the dynamo, the former serving to operate the variable resistance, as hereinafter described, and the latter serving to operate the rheotrope.
In order to illustrate the practical manner of carrying out the invention, drawings are hereunto annexed and described, in which similar letters of reference represent corresponding elements, and in which each part referred to is designated by a single letter.
Those parts not mentioned we do not claim in this our present application.
The materials of construction employed, the exact forms of design, and the proportional dimensions are not alluded to, as they are best determined upon by those versed in the art.
Figure l is a view of the devices and connections, and 1 shows the rheotrope in a changed position.
The invention, as shown in these figures, consists of the combination of the dynamo having armature A, a variable resistance, 13, in a shunt-circuit, G, to said armature, an electric motor, D, whose field-magnets E are in the main circuit F, a solenoid, G, in the main circuit, an armature, whose shaft is L, to said motor, and a rheotrope at I, both located in a sh ant, J, to said field-magnets, a screw-thread, K, out upon an extension of the shaft L of said motor, a nut, LI, fitting upon said thread, a lever, M, in circuit with the shunt to the armature of said generator, and a projection, 0, connecting the said nut to said lever The connection between thelever M and projection O is a pivot-joint. hen the main circuit becomes weak, the armature of the solenoid lowers, thus reversing the current through the motor by means of the rheotrope before alluded to and the operation of which is well known the invention.
The rheotrope shown in the figure may be replaced by any convenient rheotrope or polechanger, or the details of the one shown may be varied.
Having now stated the title, object, and relation of the said invention, having described its practical realization by reference to the accompanying drawings, having particularly ascertained the manner in which the same operates to accomplish the said object, and further stating that it is not necessary to state all the uses to which the invention may be applied, what we consider to be novel and original, and therefore claim as our invention, secured to us by the hereinbefore in part recited Letters Patent of the United States, is
1. In a regulator for a dynamo electric generator, the combination of a variable resistance in a shunt-circuit to the armature of said generator, a motor having a rotatable armature geared toa device for controlling the said resistance and located in the main circuit, and a rheotrope in circuit with said motor, substantially as and for the purpose described.
The motor reverses and intro-' armature to said solenoid, a rheotrope in circuit with said motor, alevcr located in a shunt to said generator-armature and geared to said motor-armature, and a number of resistances between the terminal ofsaid lever and that of the said generator-armature, and being in the same shunt-circuit as the said lever, substantially as and for the purposes set forth and described, and shown in the annexed specification and drawings. 7
3. In aregulator for a dynamo electric generator, the combination of an armature to said dynamo, a variable resistance in shunt to said armature, an electric motor whose field-magnets are in the main circuit, a solenoid in the main circuit, an armature to said motor, and a rheotrope, both located in a shunt to the field-magnets of said motor, a screw-th read out upon an extension of the shaft of said motor, a nut fitting upon said thread, and a le' ver having one end communicating with said variable resistances. and having the other end secured by a pivot-joint with said nut, substantially as and for the purpose set forth.
In testimony that weclaim the foregoing as our invention we have signed our names, in presence of two witnesses, this 7th day of Sep tember, 1885.
