. When the hammer pedal is released, the hammer brake start lever 32 is lowered and brings all moving parts to the blade. The first position shown in the drawing. If at this moment the board-, nodn; b1 woman, is broken or pops out of the woman or is not delayed by the brake of the hammer and the woman doesn’t fall, THEN wedge 9, lower, wedged between the cushion lOi and P1tanga 36 And, having pressed the bar 36 to the gasket 8, will delay its fall, as it together and the fall of the woman. When 1k.1gudnuyu pressure on the hammer hammer shtanga 36 will be released, in the way described above, and will give the woman a chance to fall.

In view of the fact that the adaptation is delayed. The fall of the woman is faster than it is done with the brake of the hammer, the blacksmith will not know what is holding the fall of the woman; a hammer OR adaptation, and, subsequently, it will not know whether the brake has been adjusted; the fixture will be Istrius and will cease to serve as a cj-emergency fixture. Therefore, it is necessary to introduce a sound light-signal, the purpose of the fcoTopoii to give a signal in the event that the brake brake allows the daska, raising the woman, to slip by a considerable distance .;

One of} possible options: this alarm showing pa fig. 2. Cranked lever 49 can freely rotate on: 1 its axis 56. In B1, wedge-open: lever lever 49 | A spring 50 is inserted with a hammer 51.,.
