INTERRUPTING DEVICE.
Specification of Letters Patent.
Patented Oct. 20, 1914.
Application filed May 19, 1913. Serial No. 768,638.
second street, in the city of New Yor county of New York, and State of New York, have invented a certain-new and useful Improvement in Interrupting Devices, of which the following is a full, clear, concise, and exact description.
ing devices, and more particularly to electromagnetic circuit interrupting devices for intermittently closing circuit springs at defi nite periods.
The object of this invention is to provide a device of this class comprising few and simple parts, by means of which an appreciable period of time may be obtained between circuit interruptions, and which will be ac curate and efficient in its operation.
A device made in accordance with this invention comprises generally a circuit con trolling device having an oscillating movement and operating circuit closing springs to alternately make and break a circuit through a controlling electromagnet and an auxiliary circuit which may be used for signaling purposes.
Features of the invention are the combination of the circuit closing springs with the oscillating member whereby the desired periodicity of contact closure is obtained, and other details of construction and combination of parts.
In the drawings, Figure 1 is a perspective view of an interrupting device embodying this invention; Fig. 2 is a view in side elevation of the d'evice; Fig. 3 is a plan view of the device, and Figs. 4, 5 and 6 are views illustrating the switch operating device in various positions.
Referring to the drawings, 5 designates the top member of a main frame of nonmagnetic material having the side members 6 and 7 provided with supportin extensions 8 and 9. Secured to the inner faces of the sides 6 and 7 of the main frame are magnetic pole pieces 10 and 11, and an auxiliary frame 12 of non-magnetic material carrying a magnet winding 13 for energizing said pole pieces. Secured to a shaft 15, which has pivotal engagement with the auxiliary frame 12 and the main frame, is a comparatively heavy disk 16 of non-magnetic material. Secured to this disk is an armature 17 adapted to be attracted by the pole pleces 10 and 11 when the magnet winding 13 is energized by current from a suitable I source. The attraction of the armature 17 moves the metal disk 16 against the tension of a cpil spring 20, one end of which 1 is attached to the shaft 15, the other being adjustably secured in a lug 21 carried upon I the inner face of the side member 7 of the 5 main frame.
This invention relates to circuit interrupt- E the shaft 15 which extends through the top 5 plate 5 of the main frame is a cam disk 26 :having a low surface 27, an intermediate 5 surface 28 and a high surface 29. Mounted Mounted upon a projecting portion 25 of upon a lug 30, carried by the main frame,
is a spring pile embracing two outer contact springs 32 and 33 and a central actuating spring 34. The central actuating spring has at its free end an antifriction roller 36 whlch engages the cam surfaces to open and close contact with the springs 32 and 33.
In the normal position of the parts the antifriction roller 36 rests in engagement with the low surface 27, in which position the spring 34 is making contact with the outer contact spring 32, and the spring 20 is in equilibrium. If the switch 40, shown in Fig. 4, be closed, there will be a circuit closed 1 through the magnet winding 13, including a battery 41, the contact springs 34 and 32 and the magnet winding 13. Current in this path will energize the magnet and cause the attraction of the armature 17, which will cause the disk 16 to turn in a counterclockwise direction, bringing the high surface 29 of the cam 26 under the antifriction roller 36, thus opening the contacts 32 and 34 and closing contact between springs 34 and 33, and completes a circuit through an electrical signal 45. The disk 16 being of comparatively heavy material, the momentum thereof after the circuit through the magnet coil is broken, will carry the cam through a considerable distance against the tension of the spring 20. At the end of. its movement in this direction, the disk will be returned by the action of the spring 20 thereon and will, due to the action of said spring and its own momentum, be swung into the position shown in Fig. 6, in which position the antifriction roller 36 of the spring 34 will be in engagement with the intermediate surface 28 of the cam and none of the contacts will be closed. The low surface 27 of the cam being comparatively short and the return movement of the disk 161 being fairly rapid, the antifriction roller 36 of the spring 34 will not be in engagement with the low surface 27 of the cam a sufficient length of time to close the energizing circuit of the magnet winding, but the inlermediatesurface 28 of the cam will be -moved into engagementlwith the antifriction roller 36. This movement will put t tension in the spring 20 in the opposite direction, which will move the cam in the direction it was first moved until the low surface 27 thereof comes under the antifriction roller 36, whereupon contact springs 32 and 34 will be again brought into engagement to complete an energizing circuit for the magnet winding 13 and repeat the operation just described.
A device built and operatingin the manner described can be made to produce circuit closures of low periodicity and will operate with the minimum battery consumption, due to the very short period of time that the circuit of the operating battery is closed. Furthermore, such a device is compact, rigid, can be operated in any position under any temperature conditions and has no delicately adjusted parts to require attention.
