SPECIFICATION forming part of Letters Patent No. 579,975, dated April 6, 1897.

Application filed .Tuly 3l, 1895.

To all whom, it' may concern:

Be it known that I, WEBSTER GILLETTE, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Improvement in Magneto-Electric Generators; and I do hereby declare that the following is a full, clear, and complete description thereof, reference being had to the acoompanyin g drawings, making a part of the same.

This invention relates to an improvement in magneto-electric generators; and the invention consists in novel features and economy of construction.

Figure l is a plan view of the instrument. Fig. 2 is front face view of Fig. l, showing the arrangement of driving-gear and their supports or frame. Fig. 3 is rear view of Fig. l, showing the form of the magnets and connections. Fig. 4 is an end view of shaft L shown in Fig. l, showing its connections.

In Fig. l, A represents permanent magnets. Buis an armaturehavin g trunnions C C. D is a cross-bar secured transversely to the permanent magnets A by means of bolts E E, which supports the one end of the armature B by trunnion C, passing through at or near its center. BarD has attached to it a spring F, and insulated from it by block G of non-conducting material. H is an insulating-plug entering trunnion C to within its bearing with bar D and ineasing a pin Lwhich is in turn insulated by means of an insulating-plug H. ll' is a plug inserted transversely to and abutting against the insulating-plug H, which has incased a pin l for the purpose hereinafter described.

In Fig. l a' a is a frame supporting a train of gear, a portion of which is shown in sectional view. Frame a a is secured tothe permanent magnets by the bolts E E. Attached to trunnion C/ of armature B is a pinion J. The trunnion C/ intersects the portion of the frame u.' about one-half its thickness to act as a support and free to rotate between its supports D and a. K is a toothed wheel that engages the pinion J and supported by frames a' a. L is a shaft carrying a toothed wheel in between the supporting-frames a and a and in- Serial No. 557,682. (No modelz) tersects frame u, and about the center of a abuts against trunnion C', passing through a, thus giving two bearings, an'd extends out from a" to permit the attachment of a crank or other device for rotating the same.

N is a section of inclosing case, which is preferably of insulating material. O is a sleeve of insulating material, such as fiber or rubber, which incases the shaft L and turns freely thereon. lncasing the sleeve O and iirmly attached thereto is a metallic cylinder l), having a collar P. The cylinder has an oblong square slot lt cut through its side, as also has the insulating-casing O, that corresponds with the slot R, which admits a pin S, which is secured firmly to the shaft L. To one side of the pin S is attached an insulating material S'. Secured to the metallic sleeve l) and incasing or surrounding the same is a spring T, one end of which is securely attached to the sleeve P. The other end of the spring T abuts against the insulating portion of the pin S.

U is a crank and handle securely attached to the sleeves P and G for the purpose of rotating them on the shaft L. The slot R is so arranged that in turning the crank U the insulating-sleeve O comes in contactwith the pin S. The sleeve l? is cut back, so as not to be in contact while turning.

Y is a screw having a washer which intersects the shaft L for the purpose of keeping crank and handle in position.

lV is a spring having a pin which passes through the case N and in contact with the flange P', which is connected with the spring F by means of the wire X.

To more clearly explain the action of the crank and handle, sleeves O and P, flange li", Fig. 4L shows cross-section, in which L represents the shaft, O the insulating sleeve, showing the oblong slot R, also the sleeve l with slot R in relative position to the slot in O and I), the pin S and SQ its insulating side as secured to the shaft and in relation to the sleeves F and O.

T is the spring attached to the sleeve l) at the point Z and free to act against the insulating portion of the pin S at the point Y.

It will be seen that by turning` the handle U the pin S is brought in contact with the sleeve O and will cause the shaft L to rotate, thus driving the train et gear and causing the armature B to rotate Within the poles of the permanent magnets A, thereby setting up a current oi' electricity in the coil et the armature B, which is transmitted out through 3 or ft. lVhen the handle is released, the sleeves O and P are forced back by the spring T, bringing the pin S in contact with the sleeve l), thus making contact with the shaft L, and thus ont through connections 3 and ll, as shown in Fig. l, thereby shunting the circuit by the armature B. ln Fig. l, 3 may be the incoming connection and -rt the outgoing connection, or vice versa.

By the foregoing description it will be seen that while turning the handle U the circuit is established through the spring F, pin l, and pin l', through wire on the armature out at conductor 4r.

lVhen handle is at state of rest, the circuit is established from conductor 3, through wire X, spring and pin lV to llange Fl, through l) to pin S, to shaft L, through. frame a a and gear, and out at contact et, thus shunting the armature out.

Fig. 2 is a face view to more clearly show the arrangement of the gear.

In Fig. 2 A is face view of the permanent magnet shown in Fig. l. o. ci is frame which supports the gear in which is the main dri ving-wheel, which matches into pinion l, which in turn revolves the gear-wheel l, as shown in Fig. l, which engages the pinion. J

and which is attached to trunnion C of ar mature lE.

`ln Fig. 2 Fis a collar attached to and forming a part of a sleeve P, as shown in l., which incases and is substantially secured to an insulatingsleeve 0, as shown in Figs. 'l and 2.

U is a handle attached to sleeve l, as shown in Figs. l and 2, for the purpose of revolving the train oi' gear as follows: iurnin g the handle revolves the gear-wheel m, as previously shown in Fig. l, which matches into pinion lil, which revolves gear-wheel K, which matches into pinion J, as shown in Fig. l, which is attached to the armature-trunnion Cl. The object is to increase the speed of the armature without occupying greater space.

Fig. 8 shows rear end view et Fig. l. jt is a permanent magnet. l is an armature. l) is a frame with bolts F E and spring F. l) o represent end view ot the poles ot' armature l. e is insulated wire surrounding armature B.

ln Fig. 3 it will be observed that the poles of the magnet A. are presented lnll tace tothe poles ot the armature i3, thus transmitting the full strength of magnetism to the armature while its poles are rotated between the poles of the permanent magnet A, while the pole l) rotates l'rom 3 to 5 and D from 0 to l. lt is seen that the full magnetic eltect is exercised. on the armature ll, as .its poles are in direct face with permanent magnet A. During its rotation from 3 to 5 and (l to at there is no current established within the wire surroumling armature Il. At the instant the poles ol armature l, leave the poles of permanent magnet rl a reverse polarity isset up in armature l, setting up a current of electricity l'or each change in opposite directions through the coil of insulated wire surrounding armature ll,

It will be seen that by adding more magnets and elongating the armature and bolts the capacity of the generator may be increased without other alteration of parts.

llhat l claim as my iiivention, and desire to secure by Letters Patent, is-

l. ln a m:Ignoto-generator, the combination of a series of permanent magnets, with their extreme ends presented to the tace of the armature with ashunting device, consisting ol a sleeve oi insulating material surrounding a shaft, and attached thereto a sleeve ol conducting material, having a flange at one end, both of such sleeves having an elongated slot in the same, admitting a carrying-pin inserted in the shaft on -which the insulating-sleeve operates, with a spring attached to the condnoting-sleeve, to act as a recoil to the conducting and insulating' sleeves, such sleeves being operated by a handle or other device, and such shunting device being attached to or in combination with a shaft drivinga train ol geared wheels, substantially described.
