SU62666A1 - Telegraph switch - Google Patents

Description

The telegraph switch p) allows you to turn on the telegraph device at a distance (manual or automatic) and receive messages without the part of the telegraph operator.

The drawing shows the proposed switch in general form. The main parts of the switch are two contact groups 1 and 2, an electromagnet 3 and a three-arm novorot 5.

The lever 5 is installed on the axle 14 in two columns 6 and has a spring 12. On the nose 5 of the lever 5, a tongue 7 is hinged, having a head 8 made of ebonite or another electrical material. The tongue 7 can be rotated from the initial position only in one direction (a possible tension of the tongue 7 is shown in the drawing by a dotted line). The arm 5 of the lever 5 serves to detach the pivotal plate 10 e by the bar of the electromagnet 3 from the unconnected contact 15 of the co-tact group 2. The plate 10 is equipped with a spring 16 and is mounted on the axle 13 reinforced in the posts 6. The end of the spring 1 1 16 is fastened with a clamp screw 4.

The lever 5 is held in the required position by a spring plate 9, equipped for this purpose with locking projections and fixed on the supports 6. The pin 17 is designed to hold the lever 5 in the desired position, and the screw 11 limits the stroke of the pbiiiara 5.

The drawing shows the inclusion of contact X groups 1 and 2 p of the electromagnet 3 in the electrical circuit.

When the lever 5 is rotated clockwise, the shoulder 5 moves away from the plane 10, releasing it and the electromagnet 3 bark. And the tongue 7 freely passes by the right contact of group 1, by which i diverts to the position shown in the drawing with a dotted line. As a result, the contact group 1 does not close at this turn of the lever 5. When the lever 5 is rotated clockwise, the tongue 7 with its head 8 deflects the right contact of group 1 and the joint assembly briefly closes the shunt electromagnet 3. Arm 5 of the lever 5 iijiir

This removes the plate 10 from the contact 15, the opening of the contact group 2.

Item pzoberepp

A telegraph non-switch having two contact soils and a rotary lever for influencing these groups is from the fact that, in order to use it for remote control of the telegraph apparatus, one contact group is equipped with an electromagnet blocking it the open state and connected in series to the line, and the other, normally open contact group, is under the influence of a tongue fixed on the indicated lever turning in one direction and serves for short-term bypassing the elec omagnita when turning the lever in one hundred) -on first unlocking grunpy.
