H. SCHEDLBAUER ELECTROMAGNETI C RELAY Filed May 28, 1950 1m @n Eche d1]: auer fiwflw Patented May 17, 1932 UNITED STATES PATENT OFFICE "HUGO SCHEDLBAUER, OF VIENNA, AIJ'STRIA, ASSIGNOB '10 SIEMENS & HALSKE AKTIEN- GESELLSGHAIT, OF SIEMENSSTADT, NEAR. BERLIN, GER-MANY ELECTROMAGNETIC RELAY 4 -Applmation filed Kay 28, 1930, Serial No. 456,432, and in Germany September 2, 1929.
The invention relates to electro-magnetic relays, especially for weak current purposes. The object of the invention is to create acheap relay, which is achieved according to the invention mainly in that the circuit to be controlled by the'relay passes overthe magnet circuit of the relay. Thereby the construction of the relay is considerably simplified, as special contactcarriers as well as contact springs or the like are not required, thus reducing thenumber of parts.
A particularly suitable solution of the given problem according to the invention is obtained in thatfor steering several circuits of such a relay there are provided several magnet circuits which are insulated from one another, the circuits to be controlled passing over the said magnet circuits.
Two methods of carrying out the invention are shown in the drawings.
Figs. 1 and 2 show such a relay for controlling only one circuit, the relay being shown in side elevation and plan, while .Figs. 3, 4 and 5 shows such a relay having several armatures for controlling a corresponding number of circuits.
The relay consists of the coil 1, which can contain one or more windings. The ends of the coil are limited by coil flanges 2 and 3 in the usual manner that are usually made of a fibrous insulating material. The coil of Figs. 1 and 2 surrounds a flat iron core 4,
both ends of which project out of the coil 1. One of the ends carries a connecting tag 5,
while the other end forms the pole lece for the armature. Below the coil is tted the armature 6 parallel to the core 4. This armature likewise consists of a flat iron piece is bentto a U-shape and its rear bent end is movably mounted on the core 4, but is insulated therefrom. 1t is'secured thereto b means of a perforated insulating disc 7, whic is passed over both arts. The front coil flange 3 has a slot 9,.t rough which rojects the armature 6, on the lower edge 0 which it tests in the deenergized. condition of the relay. Preferably the free end of the arma- 'ture 6 associated with the pole piece of the core 4 is provided with a contact pimple,
and is provided with a connecting tag 8. It
armature, and its contact is caused to touch the pole piece of the core 1, so that current passes between the armature and the core,
and the circuit connected thereto is closed.
In order to be able to use such a relay for controlling several circuits, it is provided with a corresponding number of magnet circuits, which are insulated from one another, as is shown in the Figs. 35, inclusive. The relay shown in these figures has, for example, three magnet circuits separated from one another. For that purpose each of the circuits to be controlled has one of each of the magnet cores 4 I, 4 I1, and 4 I11 and the armatures 6 1, 6 11, and 6 111, that are insulated from one another. The cores, as well as the armatures, are each placed next to one another in a plane and each of them has one of the soldering tags 5 1-5111, while each of the arlnat-ures has one of the soldering tags 8 I-8 111. The rest of the construction of the relay is the same as that already described with reference to the Figs. 1 and 2. When of the armatures with respect to the cores can be difierent from that shown. Also, by means of a'suitable construction of the relay, the armatures can operate front as well as back contacts.
What is claimed is: y
An electromagnetic relay comprising an energizing coil wound upon a flat iron core between two coil flanges secured on said core at substantial distances from the ends thereof, one of said coil flanges provided with an aperture, aU-shaped armature having flaring ends and arranged substantially parallel to the surface of said core, said armature projecting through said aperture and positioned thereby with one of its flared ends adjacent an end of said core, means for insulatedly fulcruming said armature at its other flared end on said core at its other end, and soldering ta s on the end of said armam ture and core. a jacent said fulcrum means whereby said armature and core may be included in an electric current circuit, said armature adapted to be moved on said fulcrum and withinsaid aperture upon the energization of said coil to engage its free end with said core, and adapted to be oppositely moved by gravity upon the deenergization of said coil, thereby closing and o ening the current circuit of the armature an core each time the coil is energized and deenergized.
In witness whereof, I hereunto subscribe my name this second day of May, A. D. 1930.
