C. W. MUSSER VIBRATOR CIRCUIT Filed Feb. 2, 1938 INVENTOR ATTORNEY Patented July 9, 1940 UNITED STATES PATENT OFFICE VIBRA'IOR CIRCUIT Application February 2, 1938, Serial No. 188,245
6 Claims.
This invention relates to electromagnetic viare both connected to a relatively stationary bratory interrupter circuits.
An object of the invention is to improve the vibrator circuits.
Other objects of the invention will be apparent from the following description and accompanying drawing taken in connection with the'appended claims.
The invention comprises the features of con- 10 struction, combination of elements, arangement of parts, and methods of manufacture and operation referred to above or which will be brought out and exemplified in the disclosure hereinafter set forth, including the illustrations in the drawing.
The figure of the drawing shows a vibrator qcircuit embodying features of the present invenion.
While a preferred embodiment of the invention is described herein, it is contemplated that considerable variation may be made in the method of procedure and the construction of parts without departing from the spirit of the invention. In the following description and in the claims, parts will be identified by specific names for convenience, but they are intended to be as generic in their application to similar parts as the art will permit.
Referring to the drawing a vibrator circuit is shown utilizing a vibrator of the type comprising a vibratory reed having an armature 30, a tongue carrying contact 33 and a pair of side arms carrying contacts 31 and 38 respectively. The reed is vibrated by an electromagnet having a core 22 and a pair of windings 52 and 53, the
end of the magnet core 22 being disposed adjacent armature 300i the reed. The mechanical structure of the vibrator may be of any type wellknown in the art. The vibrator hasassociated 40 with it in the circuit a battery 54 or other source of low voltage D. C. power and a transformer having a center tapped primary winding 55 and a secondary winding 56 of any suitable type. The two ends of primary winding 55 are connected to relatively stationary contacts 39 and 40 respectively which co-operate with reed-supported contacts 31 and 38 respectively. One terminal of battery 54 is connected to the reed and the other terminal to the mid-point of primary winding 55. Electromagnet winding 52 is connected at one end to the terminal of battery 54 which is also connected to the mid-point of primary winding 55. The corresponding end of magnet winding 53 is connected to the vibrator reed. The opposite ends of windings 52 and 53 contact 34 which co-operates with reed-supported contact 33. If desired, the reed may be grounded as shown.
At the start of the cycle of vibration the wind- 5 ing 53 has its ends short circuited by contacts 33, 34. Winding 52, however, is connected to battery 54 and to ground through contacts 33, 34, thus magnetically attracting the reed. When contacts 33, 34 are opened by the swing of the 10 reed this establishes Winding 53 in series with winding 52 and battery 54. A discharge path for the energy of winding 52 is thereby provided through winding 53 so that no arcing can take place across contacts 33, 34. Winding 53, when 15 connected in this circuit, has an opposite magnetizing effect on core 22 so that the electromagnet will be demagnetized.
While the present invention, as to its objects and advantages, has been described herein as 20 carried out in specific embodiments thereof, it is not desired to be limited thereby but it is intended to cover the invention broadly within the spirit and scope of the appended claims.
