Description

  , -,

The present invention relates to ele;

the traditional one-sided rail pedal, described in patent number 10805, - and consists of a constructive change in the part of the device used to close the electrical circuit.

In FIG. 1 depicts the view of the sfkhu on the proposed pedal; FIG. 2 is a pedal in section along the line AA in FIG. one.

The double-shouldered lever: 14, perpendicular to the rail, sits on axis 13, and on, its short arm 22 rests on a crutch-shaped rod 23 pressed by a hook (xy spring 15. On the long arm 25 of lever 14 there is a roller 24 opposite the curved protrusion 2 contact roller 1. The second lever 14 corresponds to the same protrusion 2 / on the other side of the roller 1. The Ba-; face 1 has a side elevation 4, located between the two contact levers 6 and 7, freely mounted on the axis of the contact roller. the ends of the levers 6, 7 there are triangular protrusions 8, 9 These ends are interconnected

Between the levers 6 and 7 there is a support 10 fixedly mounted on the board 5 on the same board. The contact springs 11, 12 are located on the same board. The entire device is enclosed in a casing for 16 s, with the cover 20, from-. hiding which you CAN inspect the contact roller.

When passing the train, the steam wheel (Woz 19, moving p6 to rail 18, pushes the upper part of the rod 17 and lowers the latter down. The shoulder 25 of the hatch 14 rises up and the roller 24 slides along the ledge 2, turns the roller 1. With it, turns protrusion 4, which entails the contact lever 7 until the protrusion 8 contacts the contact spring 12. The second contact lever will be held in place by a fixed stop 10; In the opposite direction of the train’s passage, wheel 19 presses the other rod 17 and the roller 1 will turn

; in, the opposite side, and the contact;

- the lever b will close the other chain through the spring 11. After the passage of the train, the spring 3 will return the turned contact lever
