UNITED STATES PATENT OFFICE.
CHARLES J. VAN DEPOELE, OF LYNN, MASSACHUSETTS.
SPECIFICATION forming part of Letters Patent No. 422,860, dated March 4, 1890. I Application filed October 4, 1889. ySerial No. 326,025. (No model.)
T0 all whom, it may concern:
Be it known that I, CHARLES J. VAN DE- POELE, a citizen of the United States, residing at Lynn,in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Multiple-Current Pulsating Generators, of which the following is a description, reference being had to the accompanying drawings, and to the lettels and figures of reference marked thereon.
My invention relates to machines for the generation and distribution of 'electric eurrents.
The invention is more particularly adapted to the subdivision of currents and the tra-nsmission of same to a plurality ot' separate circuits.
The present invention is an improvement or a development of the invention shown, described, and claimed in aprior pendingapplication filed March 23, 1889, No. 304,544, in which` prior application a novel method of producing pulsatingV or alternating currents is set forth, which consists, broadly, in the combination, with a commutator connected to a source of continuous currents, of stationary brushes placed uponlthe diameter of commutation and connected to one or more of the conductors of the working-circuits, anda brush or brushes arranged to be rotated about the periphery of the said commutator and in electrical connection with the other side or sides of the circuit or circuits represented by the main stationary brushes.
By .my present invention I not only subdivide the current at the commutator-cylinder, but I supply the same to separate circuits either in waves, impulses, or pulsations of equal period or phase or of unequal period or phase, as'may be desired. In many workshops and factories diverse species of electrodynamic machines are employed for many purposes to the operation of which pulsating electric currents might be applied, the said machines producing their best results with current impulses of different durations. It will therefore be apparent that by the present invention means are provided for furnishing from a single source of current a number of pulsating currents of speeds varying with the requirements of the work.
In the drawings I have shown a three-circuit arrangement, the current phases diifering in period in the three circuits. It will,
however, be apparent that the relative times nection with a number of separate circuits,
all or a portion thereof being desirably supplied with currents of similar phase. I
An important feature of the invention consists in supplying a plurality of pulsating currents from a single source, whether the said currents pulsate in synchronism or at different rates.
In the drawings, Figure l is a view in elevation showing aportion of a continuouscurrent armature, a commutator therefor, a r plurality of eommutator-brushes, with means,
for moving a portion thereof about the commutator, and circuit-s and connections arranged according to the invention. Fig. 2 is a view in elevation showing a dynamo-electric generator provided with a pair of stationarybrushcs and a plurality of moving brushes. Figs. 3 and 4 are theoretical views, each showing the commutator of a dynamoelectric machine provided with stationary and moving brushes, the said moving brushes being seen in different relative positions. Fig. 5 is a View in elevation, partly in section, differing from Fig. l only in the method of operating the moving brushes. Fig. 6 is a detail end view showin.;l ill aonozmtator, the fixed and moving brusl'=.-, .1* *ar for the moving brushes, as :sf- ".11 Fig.
As indicated in the 1 rawings, A is a p'er-j tion of a continuous-curren` nrntftturfa, which, as pointed out in my said pri-e." application, may be the armature of a continuous-current generator or the armature of a motor supplied with continuous currents and employed for the purpose of changing the continuous into pulsating currents.
C is a commutator of the ordinary sectional type, and B B are the main stationary commutator-brushcs arranged in operative relation to the surface of the commutator C. Although the said brushes will be hereinafter referred to as stationary, it must be under- ICO 5s. of the currents in the said circuits may be f stood that they are adjustable within the usual limits, in order that they may be shifted, if necessar f', to keep the said brushes upon the diameter of commutation.
D E F represent three separate and independent commutator-brushes, each of which is carried by a suitable holder D E F. The holders are sustained by arms d e f, said arms y being connected to sleeves G II I. The said c` sleeves are rotatably mounted concentricwith the armature-shaft a, butmost thoroughly insulated therefrom, some species of insulating `anti-friction material being interposed bel tween each of said sleeves and the other sleeve andthe armature-shaft. Pinions g h t are secured to each of the slee-ves G H I, and when acted upon by suitable driving-gear serve to I rotate' the sleeves at relative speeds deter! mined by the'size of the pinions and the nat- 29 ure of the driving-gear.l A simple form of mechanism for imparting motion separately to the said sleeves G H I, and for thereby rotating toe moving brushes about the commutatOr-AcyIinder, comprises a counter-shaft J, z5 suitably mounted with respect to the armature-shaftY a and provided with a gear-wheel 7, 1neshing with a pinion j upon the armature-shaftand imparting motion to the said gear-wheelj and shaft J. Upon the shaft J 3o are secured, as here shown, gear-wheels J J 3 j J3, meshing, respectively,`with the pinions g h lof the separate independently-rotatable Tbrush-carrying sleeves G H I. l
f ,A s indicated, the driving-gears J J 3 J3 are 3 5 of different sizes, and conseqnen tly the sleeves 'G H I, together with the eommntator-brushes carried thereby, will be moved around theA commutator-cylinder atV different rates of speed.
The above-described arrangement is empleyed where it is desired to supply currents to a number of different circuits at diierent rates of pulsation, and the circuits in connecf tion with such an arrangement may be substantially as follows: From the stationary brushesB B extend main conductors l 2. Between these said conductors are connected motor-coils M M M2 M3, the motor-coils being connected between the conductors 1 and 2by'branch conductors 3 3 4 4 5 6.
"As explained in my said prior application, `motor-coils connected between the main conductors, 'as'j ust described, would continuously receive continuous currents, and be of no avail for theV production of reciprocatory movement. According to the present inventio,n, however, conductors D2 E2 F2 are eleci' trically connected with the moving brushes D E F by suitable collector-brushes D3 E3 F3, and extend to a point at or near the central part of the motor-coils M M M2 M3, and as the said brushes D E F are moved around the commutator by the gearing and connections they approach and recede from the main stationa1ybrusl1es, and the current flowing in the respective coils iscaused to rise and fall The respective parts of the motor-coils M M M3 M3 (seen diagrammatically in Fig. l) will,- when connected as described, alternately receive eurrent-impulses, and when suitable magnetic devices, tools, or pistons are placed in operative relation. to the said coils the working' devices of different nature will be reciprocated thereby under the influence of the current-im p ulses fiowin g in the said coilsfor example, in the manner shown, described, and claimed in connection with reciprocating drilling-engines shown in Letters Patent Nos. 400,309, April 2, ISSY), and 401,231, April 9, 1889.
The coils M2 M3 are shown somewhat 'separate, and they may in that position be utilized to produce a unitary result-that is, to act to produce alternately forward and backward movement of a magnetic piston placed A of the present invention a single generator large enough to supply current for all the various purposes of the shop or factory may b e y employed, and by providing said generator with a traveling brush for each circuit of different nature the current can be subdivided, and not only subdivided, but cach subdivision be caused to pulsate withany desired rate, and in that manner both fast and slow running reciprocating electric machines can be operated from a single source of current.
It will of course be apparent that more than one reciprocating engine can be placed in each circuit, all the machines in the circuit receiving current at the same rate of pulsation.
The invention is not limited to the employment of three sets of moving brushes; but on the contrary may have as manyas desired, a separate single conductor extending between each working-circuit and its traveling brush.
In Figs. 2, 3, and t the moving brushes are indicated in several different positions; but since said brushes move at diiferent speeds their relative changes of position will be perpetual and without limit.
In Fig. 5 the invention is shown as applied to an arrangement for feeding a number of separate circuits with pulsating currents of equal phase. This is accomplished by providing a separate moving brush for each circuit, the said moving brushes being, however, all for convenience secured to a singlesupport and moving together around the commutator. lVith the arrangement seen in Fig. 5 the moving brushes BIO l, or the holders within whichthe brushes are carried, are

sustained by arms N O P', all connected,
preferably through an annular yoke O2, with a sleeve R, iotatably mounted upon but insulated from the armature-shaft a. The said arms might of course be separately connected to the sleeve R, if preferred. The armaturesliatt is provided with a pinion j', as in the previous instance, said pinion meshing with a driving-gear j, mounted upon a countershaft J, said counter-shaft' being sustained in sui table bearings within a fram e g2. The sleevev 'rings and transmit the same through circuit' conductors D2 E2 F2, which may be arranged and connected, as shown'and described, with reference to Fig..1..l
The arrangement of brushes, holders, arms, and the annular connection O2 is better seen in Fig. 6.' Y
The invention is not limited to the details shown only by wayof necessary illustration, since the forms shown may be modified and varied in many particulars without departing rom either the spiritor scope of, the invention.
Having described my invention, what. I claim, and desire to secure' by Letters Patent, is f 1. The combination, with'a source of continuous current, of main stationary brushes and circuit-connectionsextending therefrom, auxiliary connections extending to a plurality of separate working-circuits, and a moving brush for each circuit, said brushes traveling about the commutator and acting to vary the potential in the several circuitsr connected thereto.
:2. The combination of a source of continuous current, a sectional commutator and main stationary brushes, a plurality of rseparate working-circuits extendingtherefrom, translating devices connected therewith, additional circuit-connections extending from the translating-circuits, and a number of moving commutator-brushes arranged to constantly travel around the commutator, one of said moving brushes being provided for and connected to the additional conductor ot each translatiiig-circuit.
3. A system of generating and distributing currents of rising and falling potential, con- Y sisting of a dynamo-electric generator or armature of the continuous-current type, having one or more sets of stationary brushes upon the commutator thereof, a plurality of auxiliary brushes constantly moving about the commutator to and from the stationary brushes and at ditterent rates of speed, and connections between a plurality of workingcircuits and the stationary and moving brushes, whereby the current is caused to rise and fall at unequal rates of speedin the different circuits.
4. A system of generating and distributing currents of rising and falling potential, comprising a sectional armature and a sectional commutator, a set of stationary brushes upon said commutator, and a' plurality of brushes and means for constantly moving said brushes upon the sectinal commutator toward and away from the points of maximum and zero 8o electro-motive force, and a plurality of sep-XV arate workirig-circuits` connected to the sta-` tionary'and moving brushes, and in which thep'otential is caused to rise and tall in accordf ance with the rate of movement of the traveling brushes.
5. A system of generating and distributing currents of rising and falling potential, 'coni sisting of a sectional armature and a sectional commutator, a set of stationary brushes upon said commutator, and a plurality of movable brushes, each brush being provided with separate` means for moving the same about the commutator toward and away from the,A points of maximum and zero electro-'motive force, .and workingcircuits connected, respectively, to the stationary and to the moving i brushes, whereby the potential is caused to rise and fall in each working-circuit in accordance with the rate of movement of each roo traveling brush.
' 6. The combination, with a source of continuous current, a sectional commutator, stationary brushes therefor, and workingcircuits extending from said brushes, ot transm5' latiiig devices in said circuits, additional connectioiis extending from the translating-cin.
cuits to additional brushes upon the coinmutator, and means for constantly moving y the additional brushes around the commu-iro tator toward and away from the diameter of' commutation, singly or together, and thereby constantly varyin g the potential in the tran s lating-circuits.
In testimony whereof I hereto affix myA sig- '115 nature in presence ot two'witnesses.
