SU38690A1 - Device for automatic closing of the semaphore at breakage of semaphore t g - Google Patents

Description

The device for automatic closing of the semaphore, at the break of its drive tubes, described in the main author's certificate No. 17352, consists in that in it the wings of the semaphore are connected to the pulley bzyk, on which the drive rods are attached through one axis of the chamber, which encloses the dogs and the cams interacting with them, fixed on the sews independently of the camera. When any drive gear is broken, the wing drops and cBoiM weighs the indicated camera, causing the two cams of the turn 11 placed in it to move in opposite directions until one of them stops the cracker in the chamber, and thus stops turning the chamber at that time when the servant associated with it takes the position of closing the semaphore.

When the device is attached, it is also possible to quickly restore the effect of the semaphore after the break of the irivodous rod by simple tension.

a broken cable, which causes all parts of its communication with the wing (cams, dogs, pulley, etc.) to be retracted and the wing remains closed. But during experiments with a device in this form, the disadvantage was discovered that, due to the presence of a stubborn cracker in it, it was possible to open the upper wing when the non-working rod was broken if it was pulled over the working rod.

To eliminate this drawback, a modified device is proposed, the device of which in general remains the same, but in whom both dogs and rusks, whose purpose is assigned to the ledges made in the chamber, are eliminated, the cams are delivered more than that they are consumed by the tension of driving TCs in different directions, and when one or the other is broken, they approach each other in contrast to the main type of device, where the tension cams approach each other, and when they break, they diverge in different directions.
