4 Claim.
This invention relates to electric oscillators and particularly to a construction of this character in which a wheel is oscillated in opposite directions automatically, this oscillation of the wheel being capable of being used to control timing devices, flashing signals, time limit relays, toys, vibrators, electrical interruptors and many other similar uses. The general object of the invention is to provide an oscillator or interrupter of this character which is particularly simple and may be cheaply made, requires but little power, is particularly compact and secures a perfect operation under wide variations of temperature.
A further object is to provide means whereby the range of oscillation of the wheel may be varied within relatively wide limits, thus varying the time or number of oscillations per minute.
Other objects will appear in the course of the following description.
Our invention is illustrated in the accompanying drawing, wherelnz- Figure 1 is a side elevation of the oscillator, the frame being shown in section and the electrical connections being shown diagrammatically;
Figure 2 is an elevation of the armature and magnet, the frame being in section.
Refen'ing to the drawing, in designates a base of insulating material supporting p n it the frame ii of metal." This frame has extending across it the supporting braces i2 riveted to the frame at l3. Extending through these supports orbraces I2 is a shaft i4 carrying upon it the wheel I! which at one point is provided with a weight l6 so that the wheel' is unbalanced.
Diametrically opposite the weighted portion IE is an outwardly extending lug ll of insulating material but rigidly fixed upon the wheel. Disposed in the path of movement of the lug or arm I1 is an impact block i8 supported by a coiled compression spring [3 in turn-carried by an ad- Justing screw 20 passing through the frame ll preferably adJacent the base "and held in ad- Justed position by the lock nut 2 I.
Disposed as fliustrated in the upper portion of the frame is a magnet 22 shown as supported by the screw 23. Associated with this magnet is the armature 24 pivoted at to the frame and urging this armature outward away from the core of the electro-magnet 22 is a retractile spring 23 which is connected to an adjusting screw 21 through the frame and through an inaulating block 28 supported by the frame. This adiusting screw is held in adjusted position by the lock nut 29 or any other suitable means. Thus the tension on the spring 26 may be adjusted.
The armature 24 carries upon it an insulating piece 30 against which the spring 26 bears and also carries upon it a contact 3i which is insulated from the armature. Mounted upon the face of the armature which confronts the electromag'net is a leaf spring 32 and carried by this leaf spring is a contact 33. This leaf spring is held in place in any suitable manner as by the 1 pin '34, but this pin and spring are insulated from the armature.
Extending from the spring 32 is a conductor 35 which is loose or formed in a spiral so that the armature may easily vibrate. The pin 3| is connected by a conductor 36 to the spring 26.
The coil of the electro-magnet is connected at oneend to a conductor 31 which extends through an insulated opening in the frame i I and extends to a switch 33. This switch is connected to a 2 battery 33 and the other pole of the battery is connected by a wire III to a binding post 4| on the frame Ii to which. binding post the conductor 35 is connected. Also extending from the binding post 4| is a conductor 42 which is connected to a a;
The operation of this structure is as follows:-, Normally the leaf spring 32 is biased outwardly 31 so that the contacts 33 and 3| are supported from each other and, therefore, no current passesto the electro-magnet. On starting this oscillator, the wheel i5 may be turned until the lug II has. compressed the spring It a certain amount. 3 Upon the release of the wheel, the rebound of the spring [9 will swing the wheel in a clockwise direction in Figure 1 until the lug l'l strikes the spring 32. This will push the armature 24 away from the electro-magnet until the resilience of 4f the spring 32 has been overcome. Then the contacts 3i and 33 will touch and current will pass from the battery 39 to the coil of the magnet 22, which, being energized, will attract the armature 24. in Figure 1 checking the rotation of the wheel in a clockwise direction and reversing this rotation so that the wheel will now oscillate in the opposite direction until the lug II has again compressed the spring l3. As soon as the strength of the so spring I! becomes greater than the inertia of the wheel, the spring i9 will rebound, reversely rotating the wheel and so on.
With this construction, the range of movement of the wheel i 5 and hence the number of oscllla- 66 The armature will move toward the left 44! thus given to the wheel per minute may be ment or the wheel, thespring,
varied by retracting the spring 19 and the impact block I 8 or shitting it forward, that is, toward the left in Figure 1. This will secure a variation in the range 0! movement of the wheel from 150 to 220, thus securing a wide variation of the number of oscillations per minute.
It will be seen that the device is extremely simple, that it may be very compactly made, and that it requires but few parts and these are not likely to getout of order. which the wheel I! is mounted may be used for making or breaking a current through time limit relays, vibrators, signals or the like and that the device may be used as an oscillator for securing the oscillations or corresponding movements of any device to which the shaft Il may be attached.
While we have illustrated certain details of construction and arrangements 01- parts, it is to be understood that many changes might be made therein without departing from the spirit of the invention as defined in the appended claims.
