RELAY Filed Jan. '7, 1957 Mlllllllll lll\ s 50 /N VE N TOP 5/ C By W. BRANDT 48 A item/Er Patented May 30, 1939 UNITED STATES PATENT OFFICE RELAY Walter Brandt, Vienna, Austria, assignor to Western Electric Company, Incorporated, New York, N. Y., a corporation of New York Application January 7, 1937, Serial No. 119,428 In Austria. March 23, 1936 8 Claims.
.usual manner by the attraction of the relay armature in response to the energization of its winding by direct current and with one or more additional sets of springs which are so tuned as to be operated when the relay winding is energized by alternating currents of one or more predetermined frequencies. It is to be understood, however, that the relay of this invention is equally applicable to systems other than party iine teie phone systems.
For a clearer understanding of the invention reference may be had to the following detailed description taken in connection with the accompanying drawing of which:
Fig. 1 shows one embodiment of the invention;
Fig. 2 shows a second embodiment of the invention;
Fig. 3,is a side elevation of a further embodiment of the invention; and
Fig. 4 is an end elevation of the relay structure disclosed in Fig. 3.
Referring now to Fig. 1,-the relay disclosed therein comprises a heel-piece I, a core 2 secured thereto by the screw 3, an energizing winding 4 on the core 2, an armature 5 pivoted on the forward end of the heel-piece l and cooperating with the pole-face of the forward end of the core 2 and-a spring pile-up 6 insulatedly supported on the heel-piece I. The movable springs of the pile-up 6 are operable into engagement with the stationary springs of the pile-up by the operating studs 1 and 8 through the movement of the rear end of the armature 5 when the armature is attracted toward the core 2 by the energization of the winding 4. In addition, a pair of tuned resonant springs 9 and i is provided, spring 9 being secured to a stationary support I l and spring I!) being insulatedly secured to the armature 5. The springs 9 and I 0 are so tuned as to become closed in response to a definite frequency. If desired, a second pair of similar springs tuned to be responsive t9 a different frequency may be similarly mounted with respect to the armature 5. A spring member I2 is also provided attached at one end to the heel-piece i by screws I3 and with its free end overlying the pole-face of the end of core 2. Instead of the spring member 12 an elastic bumper of felt, rubber or other similar material may be used.
If now direct current is applied to the winding i, the armature is attracted towardthe core into engagement with the spring l2 and the contact springs of the spring pile-up ii are operated in the usual manner. If now alternating current of a predetermined frequency is applied to the winding the armature vibrates in response thereto due to its engagement with the spring member 52, there's-y causing the spring ill to vibrate with such amplitude as to engage with the fixed sprin o.
The relay shown Fig. 2' is similarly provided with a heel-piece core 22 secured thereto by the screw 23, winding 25, armature 25 and spring pile-up 26, butthe tuned resonant spring and fixed spring 2d are mounted to be operated not by the vibration of the armature 25, but by a sepa rate armature. spring 29 is insulatedly mounted on a bracket 3i secured to the relay structure by the screw 23. The spring at is secured to the heel-piece 2i by screw 32 and a smali armature 33 is attached by a screw 34 to the spring 30 andcooperates with an opening 35 in the heei-piece.
when direct current is applied to the winding 24, the armature 25 is attracted toward the core 22 thereby operating the springs of the pile-dip 26. If now alternating current of a pre-deter inined frequency is applied to the winding 24 the small armature 33 is vibrated within he opening 35 in the heei-piece transmitting its vi brations to the spring 39 which will thereupon engage with the fixed spring 29.
In Figs. and 4 a relay of the flat type is disclosed which functions in the same general manner as the relay disclosed in Fig. 1. This relay comprises a heel-piece 4!, a core 42 secured thereto by the screw 43, an energizing winding 44 on the core 42, an armature 45 pivoted by a knife edge on the forward end of the heel-piece 4i and a spring pile-up 46 operable by the operating stud 41 carried by the armature. The forward end of the armature 45 cooperates with the poie piece 48 secured to the forward end of the core 42 and is provided with two ears 49 and 50 between which a steel wire or ribbon Si is stretched. To afiord clearance for the free vibration of the wire ii, the pole piece 48 is provided To accomplish this the fixed with a laterally extending groove 52 as most clearly shown in Fig. 3. With the armature 45 in its normal or unattracted position the mid-point of the wire 5| rests upon the end of adjusting screw 53 which is threaded through the pole piece 48.
'In addition to the spring pile-up 46 a pair of resonant springs 54 and 55 is provided, the spring 54 being insulatedly attached to the free end of armature 45 and spring 55 being insulatedly attached near the rear end of the heel-piece 4|.
When direct current is applied to the winding 44, the armature is attracted against the tension of the wire 5| toward the pole-piece 48 operating the springs of the spring pile-up 46. If now alternating current of a predetermined frequency is applied to the winding 44, because of the elastic support of the free end of the armature by the wire 5| engaging with the end of the screw 53, the armature will vibrate in response to the alternating current transmitting its vibrations to 1 the spring'54 which will then engage with spring .What is claimed is:
