MAGNETO MACHINE.
APPLICATION FILED MAY 1. F915.
1,180,426. Patented Apr. 25,1916.
0; 5 4 2 $HEET$SHEET 2- veniently be similar to the bracket illustrated in Reissue Patent No. 13,878, granted to Emil Podlesak on February 9, 1915.
Disposed upon the pole pieces 10 and located between the permanent side plates 12 is a late 21 of non-magnetic and non-conductive material which, as illustrated, may conveniently carry a terminal block at 22. At 23 we have illustrated a cap, which in combination with the upper ends of the permanent side plates 12-12, constitutes a. housing for the several instrumentalities supported by the plate 21.
At 24-24 we have illustrated the generating windings of our improved magneto machine, each of which generating windings is disposed upon the middle polar projection of one of the laminated pole pieces 10. The generating windings which are electrically connected in series are solely retained in proper position with respect to their associated pole pieces by friction and by means presently to be explained.
At 25 and 26 we have illustrated removable side plates adapted to be secured to the ermanent side plates 12 by screws 27-27. t will be noted that each of these removable side plates is provided with a more or less annular flange on its inner face, which flange extends through the aperture 12 in the associated permanent side plate 12 and is disposed adjacent the generating windings 24-24:. It will thus be seen that when the removable side plates 25 and 26 are in the positions illustrated in Figs. 1 and 2 of the drawings, the inwardly extending flanges of the removable side plates 25 and 26, illustrated respectively at 25" and 26, effectually serve to retain the generating windings 24 in proper position and to prevent displacement thereof. Each of the removable side plates, 25, 26, is moreover provided on its inner surface with a of depressions, most clearly illustrated"at;28 in Fig. 7 of the drawings, these depressions serving to receive the adjacent endslof the generating windings 24 when the side plates are in proper position, as illustrated in Fig. 1. The removable side plates 25 and 26 moreover provide bearings for a shaft 29, which shaft carries a rotor 30 of laminated material and which rotor has four radial arms and substantially the cross section of a Maltese cross.
It is to be understood that when the rotor 30 is oscillated in proximity to the polar projections of .the pole pieces 10-10 the rapid change of magnetic lines through the generating windings inducesan electr c current in the windings. It will, not be necessary for us to describe the cotiperation of the rotor or inductor with the projections of the pole pieces 10-10, inasmuch as thea Patent No. 1,098,052, granted to Emil Podl'esak on May 26, 1911, illustrates and describes in de tail a magneto machine comprising substantially E shaped pole pieces and a laminated 1nductor having four radial arms. Our present nvention is not particularly concerned with the details of the rotor and pole pieces, but is rather directed to the several features-set forth in the claims appended to this specification.
The removable side plates 25 and'26 are desirably provided with receptacles for'oiled felt pr other suitable material for properly lubricating the shaft bearings, these devices being illustrated most clearly in Fig. 4.
Keyed upon the end of the shaft 29 adjacent the removable cover plate 25 is a yoke 31 normally retained in a horizontal position by helical springs 32-32 interposed between the arms of the yoke 31 and the projecting end 17 of the end plate 17. In this respect our present magneto machine does not materially differ from 'the'devis illustrated in the patents to Emil Podlesak previously referred to.
The end of the shaft 29, adjacent the removable cover plate 26, has keyed thereon a collar provided with an integral trip finger 33 and a tail piece 34. These parts are not essentiall difl'erentfrom the corresponding devices il ustrated in reissue patent to Emil Podlesak, hereinbefore referred to and for the pur oses of the present specification it will su ce to say that the trip finger 33 is adapted to be engaged by an engine driven actuator to actuate the inductor against the tension of its associated springs 32, and that the tail piece 34 serves to operate the make 100 and break electrodes (not shown) after the inductor has been moved by the engine driven actuator and released. The Podlesak reissue patent illustrates in detail how the trip finger 33 is actuated by the engine 5 driven actuator and how the tail piece 34 effects operation of the make and break electrodes, so for the purposes of this specification it will not be desirable for us to explain the construction and mode of operation of 110 these parts in detail.
From the foregoing description it will be seen that the laminated pole piecesare rigidly and ermanently carried with the permanent side plates 12-12 and that the re- 115 movable side plates 25 and 26, which provide bearings for the inductor shaft, effectually serve to retain the generating windings 24-424 in proper position. When it becomes necessary or desirable to obtain access to the 120 generating windings or the polar projections the inductor maybe withdrawn from operative position betweengthe pole pieces by sunply removing thefsprings 32-32 and the collar which provides the trip finger 33 and 125 the tail piece 34, from? the inductor shaft and unscrewing the side plate 25. The several parts illustrated in Fig. 6 may then be drawn away from the other parts of the magneto machine. Access to the generating 130 to those skilled in the art to which our invention relates.
Having thus described our invention what we claim as new and desire to secure by Letters Patent of the United States is:
1. A magneto machine comprising in combination with a pair of oppositely disposed pole pieces a pear of permanent sideplates carried with said pole'pieces, each of said permanent side plates having a central aperture therein, generating windings carried by the pole pieces, a pair of removable side plates, one associated with each of said permanent side plates, flanges carried by said removable side plates extending into the apertures in the permanent side plates to retain the generating windings in position upon their respective pole pieces, and a rotor having bearings-in said removable side plates.
2. A magneto machine comprising in combination a pair of oppositely disposed substantially E-shaped pole ieces, a pair of permanent side plates carried with said pole pieces, a generating winding disposed upon .30 the middle arm of each of said E-shaped side plates affording pole pieces, an inductor movable in proximity to said pole pieces,)a pair of removable ductor, and means carried on the inner face of said removable side plates, conformed and disposed to retain said generating winding in position upon its associated Pole piece.
earings for said in- 3. In combination, a pair of substantially E-shaped pole pieces, a pair of permanent side plates carried with said pole pieces,each of said permanent side plates provided with a central aperture, a generating winding disposed upon the middle projection of each of said pole pieces, an inductor movable in proximity to said pole pieces, a pair of removable side plates aflording bearings for said inductor, and projections on the inner faces of said removable side plates extending into the apertures in said permanent side plates to retain the generating winding in osition upon its associated pole piece.
n witness whereof, we hereunto subscribe our names, in the presence of two witnesses, this 27th day of April, A. D. 1915.
