DRlVlNG-GEAR FOR MAGNETO-ELEGTRiC MACE-ii SPECIEIGATION forming part of Letters Patent No. 298,160, dated Fekrnaiy 5, 1884.
Application filed September 3, 1950.
To (LZZ/ whom, it may colccern:
- Be it known that I, EZRA T. GJLLILAXD, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Driving- Gears for ilIagneto-Electric Generators and Similar Apparatus, of which the following is a specification.
The object of my invention is to produce a driving-gear for inagnetoelcctric generators which shall operate, when put in motion, to automatically make or break an electrical circuit, as the case may be. This object is preferably accomplished by providing one of the wheels of the gear with an insulated hub, and mounting the same loosely upon its shaft, upon which is rigidly mounted a drivingarm, not insulated therefrom, which arm passes between two pins or points upon the lace of said wheel, one of which shall be separated from said arm by insulating material, and the other shall not, and providing means by which said arm shall be kept in. contact with one of said pins at all times when at rest, while the force employed to drive the engine shall throw said arm against the other pin.
Referring to the accompanying drawings, which are made a part hereof, and in which all portions constructed of insulating mate rial are distinguished by being drawn in solid black Figure 1 is a vertical section, on the dotted line :v :v of Fig. 2, of a magnetoelectric g encrator having my improved drivinggear; Fig. 2, a horizontal. section thereof, looking downwardly from the dotted line ;2 3 of Fig. 1. Fig. 3 is an elevation of the gear-wheels and parts connected therewith, as seen from the dotted line 5; and Fig. l isa perspective of the wheel having my improvements attached.
In said drawings, (which illustrate the in vention in the form wherein the act of putting the gear in motion operates to break the electrical circuit,) the portions marked A rep resent the box or frame-work in which the generator is mounted; B, the cylinder of the generator; G, the magnets; D, the driven wheel of the driving-gear, mounted on the shalt of the rotary armature in the cylinder; ID, the driving-wheel of said gear, having studs or pins 0 c c thereon, and which is electrically separated from the shalton which it is mounted by having its hub lined with insulating material; F, a driving-arm attached directly to the same shalt; F, a spring to hold said'arm in position; G, the shaft to which the wheel E and arm Fare connected; H, a crank for turning said shalt, I, the bearingbox in which said shalt runs; J, a spring, against which a projecting point from the rotary armature rests; K, a wire or other electrically-connecting device running from said spring or said point to said bearing-box or said shaft, a continuation of which is one of the line-wires; and L, the other linewire or strip,which leads from any convenient point on the generator.
The operation of myinvcntion is as follows: The wheel E, being loosely mounted on the shalt G, of course moves freely thereon. The arm F, being rigidly mounted on said shalt, moves therewith. The studs 0" c on the wheel i E,being firmly afiixed thereto on each side of i the arm F define its independent movement. The spring F, being attached -to the stud e and the arm F,kceps the latter always in contact with the stud 6-, except when forcibly re moved from said contact. The turning of the crank supplies the necessary force, and, with the resistance of the magnets, operates to pull out the spring and bring the arm into contact with the stud 0 instead of the stud 07-. The wheel I] being insulated both from the arm and the shalt, and the studs 0 and 0" being both covered with insulating material, the electrical connection that would otherwise cut out the generator is completely broken by the operation of turning, while, as soon as the turning ceases, the arm is again, by the force of the spring. brought in contact with the uniusulatcd stud 0*, and thc'electrical connection cutting out the generator is re-establishcd. The eleetrical circuit illustrated herein passes through the wheel-shaft, the driving-arm, the two wheels, the armature, the spring (I, and the wire K, back to the shaftor its bearing-box; but of course a particular arrangement of ill parts is not essential so long as the circuit exists.
The use to which I have applied my invention is in telephone call signal apparatus, where the resistance of the generator is automatically cut out by its use when the appawith the driven wheel with exactly the same electrical result, and with only the mechanical difference incident to the changed relations, viz., that in operation the wheel would then drive the arm and the shaft instead of the arm driving the wheel, as in the construction shown.
There may be cases where it would be desirable to reverse the action described and make instead of break anelectrical circuit. In such a case it'is only necessary to reverse the position of the plugs or pins 6 and c.
This device may also be constructed with both pins non-insulated, and a piece of insulating material attached to one side or the other of the drivingarm where. it comes in contact with the pin or stud.
Having thus fullydescribed my said invention, what I claim as new, and desire to secure by Letters Patent, is
1. In combination with a magneto-electric generator, a driving-gear in which the shaft carries both a wheel and an arm, the wheel being loosely mounted on said shaft, and insulated therefrom and from the arm, and the arm being rigidly mounted on the shaft and arranged to pass-between two projecting studs or points 011 said whee], one of which is insulated from electrical contact with said arm, and the other is not, and which is provided with means for maintaining the contact between the arm and one of said points when the apparatus is at rest, but which shall not operate to prevent a contact from being made between the arm and the other point when the apparatus is put in motion, substantially as set forth.
2. The combination, in a driving-gear for magneto-electric generators, of a wheel insulated from the shaft thereof, an arm on said shaft which is at times insulated by means, substantially as described, from the wheel, and at others not, one of which said conditions shall result from the mechanical act of turning the wheel and the other from allowing it to remain at rest, and means for maintaining the proper contact when the apparatus is at rest, substantially as set forth.
The combination, in a driving-gear for magneto-electric generators, of a shaft, a wheel and an arm, the wheel and arm being-mounted on the shaftand so connected, by means substantially as described, that an electrical circuit passing through them shall remain uniformly either open or closed when the apparatus is at rest, but in which the mechanical act of turning the wheel shall operate to au-. tomatically change the condition of said electrical circuit, substantially as set forth.
4. The combination, in a driving-gear for maguetoelectric generators, of a shaft, G, an arm, F, a spring, F, a wheel, E, having a hub of insulating material, and studs or points on said wheel with which said arm comes in contact, substantially as and for the purposes set forth.
5. The combination, with a main circuit and a maguetoelectric machine, of a shunt or short circuit around the machine, and means consisting of an arm, two points between which it vibrates, one of which is, insulated and the other not, and a retractile spring whereby such short circuit is, immediately upon and continuously during the operation of the machine, broken and kept open, substantially as set forth.
6. The combination, in a drivinggear for magneto-electric generators, of a shaft, a projeetion thereon, points with which said projection comes in contact, and a spring, said projection forming a part of an electrical circuit when in one position, but, by means of insulating material, being cut out when in another position, the mechanical act of turning the gear and the action of the spring being the means of effecting said change of position, substantially as set forth.
In witness whereof I have hereunto set my hand and seal at Indianapolis, Indiana, this 31st day of August, A. D. 1880.
EZRA T. GILLILAND.
