UNlTED STATES TENT JOHN F. TOOMEY, OF NEW YORK, N. Y., ASSGNOR TG AMERXCAN TELEPHONE AND TELEGRAPH COMPANY, A CORPORATON .OF NEW YORK.
CIRCU'E CONTROLLER.
Application filed october 10, 1919.
My invention relates to circuit controllers, particularly to controllers for operating a series ot electrical contacts consecutively in one direction or the other, a definite predetermined interval of time elapsing before the operation ot each Contact.
In the preferred form of embodiment ot the invention a disc oit magnetic material is revolved in one direction or the other by an electric motor, according to the direction oi the current controlling the motor. A Contact arm is mounted adjacent the magnetic 'disc and provided with a winding for at times attracting the arm to the disc and 'thus causing it to rotate in unison therewith. Contact points are provided to be engaged by the contact arm when the same is rotating,
and a spring is employed for disengaging theV arm from the disc when the electromagnet is deeirei'gized so that the arm is returned by gravity to its normal inoperative position.
A good understanding of the invention may be had by reference to the following drawing, in which Figs. 1 and 2 are views showing side and iront elevations, respectively, of one form ont embodiment otmyinvention; liig. 3 being a diagrammatic view showing one form and arrangement of circuits ter controlling the apparatus shown in Figs. 1 and 2.
Similar characters of reference refer to similar parts in each of the several views.
In the drawing numeral 1 designates a base plate on which is mounted a standard 2, the upper portion ot' which is in the shape of an inverted U, having front and rear members 2, and 2l. Mounted in this iframe is a shaft 3, to which is secured a disc 5 of magnetic material having wormwheel teeth in its edge, driven by a. worm 6 on the shaft of a motor 24, not shown in Figs. 1 and 2 to avoid unnecessary complication. An arm 4, also of magnetic material, is mounted loosely on shaft 3, this arm being provided with a magnetizing winding 8, one end of which is grounded to the frame ot' the machine at point 9, and the otherV end of which is connected to an insulated contact ring 10, cooperating with a brush 11. VVh'en winding 8 is energized by current supplied through brush 11, magnetic flux traverses the arm and the disc 5, so that the arm slides on shaft 3 toward the disc until an abutment 4a on the arm engages the face of Serial No. 329,801.
the disk. A spring 13 is placed on sha'lt 3, between disc 5 and arm 4, to return the arm to its initial position when the winding 8 is deenergized. Adjacent to its' extremity, arm 4 is provided with an insulated contact brush 14, which brush is adapted to engage contact points 16 mounted on a semi-circular plate 18 of insulating material, which plate is secured to `trame 2, concentrically with shaft 3, by means of a screw and sleeve 20 and by a strap 21.
The operation of the controller may now be readily understood by having reference to Fig. 3 in which is illustrated a. battery 22 for supplying current to the armature of motor 24, (the field 01' which has not been shown) through a reversing switch 25, which thus governs the direction of rotation of the motor. The current for the winding 8 is also supplied from battery 22, a switch 26 being employed to govern the circuit of both the winding and the motor. Vhen switch 26 is closed, arm 4 moves into engagement with disc 5, and motor 24 rotates the disc in a certain direction, say to the left. The contact brush 14 is thus swept over the contact points 16 successively lrom lett to right and operates circuits which may be associated with the contact points in any suitable manner. The speed of rotation ot arm 4 is determined by the worm gear ratio, and the speed oit the motor, and a delinite interval of time elapses between the closure of switch 26 and the operation ot' any one of the contacts, which interval may be made large or small, as desired, according to the position of the contact points on plate 18. 1li-Then switch 26 is opened, the motor ceases to rotate and the winding 8 i'ails to hold the arm against the face of the disc 5, so that the saine falls back into the position shown in the drawing. The contacts are not operated as the arm returns because spring 13 forces the arm away from the disc so that the brush does not touch the contactpoints.
`When switch 26 is closed with switch 25 reversed, the contacts are operated in the reverse order.
Although in the form of embodiment of the invention shown and described herein only one circuit controlling device is operated by the motor 24, it is readily understood that this has been done by way of example, and' the invention is not limited to a single contact arm to be actuated by the one motor.
Various uio liiieations may be marde within tliescope ol the following claims Without departing from the Spirit and Scope of the invention.
'WVlmt I claim is:
1. In combination, a rotating dise of 11mgnetio material, a Contact arm of iiiiugnetie material mounted eoncentrieally with said (lise, an eleetroiriegiietie device Lfor at .times attracting Seid arm to seid dise zuid Causing the same to rotatetlierewitl1 means normally tending' to diseiigage @girl arm from Suid dise, and a eontactpont operated bysaitl arm.
2. In eoii'ibiimtioi, a (lise olimagnetie mu- .name tothi' speeiliezition this Qtli (lay oi.
