T 0 all whom it may concern Be it known that I, FREDERICK R. PARKER, av citizen of the United States of America, residin at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Relay, of which the following is a specification, reference being had to the accompanying drawing illustrating same.

This application is a division of my application from which United States Letters Patent No. 1,226,617 issued on May 15, 1917, on electromagnet.

My present invention relates to that class of electrically-operable devices known as relays.

The principal objects of my invention are, to .provide an improved relay or electricallyoperable device substantially as herein set forth to provide improved switching mecha nism for such relays or electrically-operable devices; and to provide improved means for operating the switching mechanism of such relays or electrically-operable devices.

Other objects will be apparent from the following specification.

The figure of the drawing is a side elevation of one preferred construction of my im-.

proved relay, showing the relay mounted to a mounting strip. In the figure a portion of one of the insulating spool heads is shown broken away to show the apparatus more clearly.

Referring to the drawing, 1 is a magnetizable core upon which an energizing coil 2 is wound. 3 and 4 are heads of insulating material which are forced onto the core 1 and form therewith a spool for containing the winding 2. 5 is an L-shaped member of magnetizable material which is attached to the rear end of the core 1 preferably by a bolt 6 extending into the rear end of the core 1. One leg of the member 5 extends substantially parallel with the core 1 between the spool heads 3 and 4, preferably as shown, and is attached to the heads 3 and 4 in any suitable manner. 7 is a mounting strip intended for mounting a number of relays thereon. The relay of the figure is heldto the strip 7 preferably by nuts 8 8. 9 and 10 are switch sprin s which are preferably carried by the head portion 4. The springs 9 and 10 are insulated from each other in any suitable manner. 11 is one of a pair of terminals for the ends ofthe wind ng 2, whlch are extended through the head portion 4 and carried thereby. The end 12 of the winding 2 may be attached to the terminal 11 as shown, preferably being soldered thereto. 13 is an armature which is preferably made of comparatively thin magnetizable material and mounted pivotally to the free end of the L-shaped member 5 preferably by a screw 14. The upper or inner end of the armature 13 preferably carries a pin 15 of insulating materialcadapted to bear against the switch spring 9 and operate it when the armature 13 is operated. 16 is an adjustment screw for limiting the backward movement of the armature 13. The front end of the core 1 is preferably cut out as shown to accommodate the armature 13 and provide a portion 17 extending forwardly to within a short distance from a second armature 18. The armature 18 is preferably made of comparatively thick magnetizab-le material and is pivotally mounted at 20 between or on brackets 19 which are attached to the spool head 3. The armature 18 preferably overlaps the armature 13 and preferably carries an insulating roller 21 at its free end adapted to bear against the switch spring 10 and operate it when the armature 18 is operated. 22 is an adjustment screw for limiting the backward movement of the armature 18. Any other details of construction of the device are thought to be well understood'without further description.

As to the operation of the relay, when a small energizing current of the proper intensity is sent through the coil 2, the magnetic circuit 1 5 13 becomes sufliciently magnetized to cause the core 1 to attract the armature 13 thereto, thus operating the spring 9 and causing it to engage the spring 10. The armature 18, however, will not be attracted by the magnetism produced by this weak energizing current. When a larger energizing current of the proper intensity is sent through the coil 2, the magnetizable portions 1 5 13 18 become sufficiently magnetizedto cause the attraction of both of the armatures 13 and 18 toward the core 1, provided the armature 13 was not already attracted by a weaker energization of the device, in which latter case the armature 18 alone will be attracted by the increased ener-i gization. The attraction of armature 1 8 operates the spring 10 and author takes 1t out of contact with spring9 which was previously operated, or keeps the contact 9 10 open in case both of the armatures are operated simultaneously. The armature 18 when attracted therefore opens the switch 9 10 orelse maintains it in open condition.

Then a small energizing current is first turned on through the winding 2 and is then increased sufficiently, the armature 13 first closes the switch 9 10 and then the armature 18 opens the same switch. Reversely, when there'is a largeenergizing current passing through the winding 2 and it is then reduced sufiiciently, the armature 18 first closes the switch 9, 10 and then the armature 13 opens the same switch, this latter operation preferably taking place when the energizing current 1sreduced close'to zero. I may utilize these operations of the armatures and their control of the switch in certain places to greatfladvantage. as, for instance, in telephone systems, for various purposes including the control of signaling devices and especially supervisory signaling devices. The backward operations of the armatures 13 and 18 may bcaused by the pressure of the springs 9 and 10 thereon,or by gravity, or both...

I desirec t to be understood that Imay control a great number of combinations of switch springs or members by means of the armatures of my relay, and I therefore do not wishto be limited in this invention to the particular switch shown.

I also wish it to be understood that in certain modifications ofmy invention I may use any number of coils or windings on the core 1 for magnetizing same.

WVhile the construction of the relay herein shown provides a very sensitive and efiicient device, I do not wish to be limited in this invention to the particular construction shown, as various modificatlons thereof may be made or utilized without departing from the scope of the appended claims.
