In FIG. 1 is a front view of the device; FIG. 2 is a section along the line AB of FIG. one; FIG. 3 is a top view of the clutch device; FIG. 4 is a section along the line CD of FIG. one; FIG. 5 is a front view of a steam distribution valve device; FIG. 6 is a side view and FIG. 7-t-vertical section of the valve along the line a 6 (Fig. 5).

In the tide 8 of the body of the crosshead 1 (Fig. 1, 3), there is a channel 3, which serves to pull out and move the crosshead roll 6-6 and the pinch drawbar connected to it when the crosshead is turned off, having a socket 5 on the inner side (Fig. 2, 3, four)

for the fist 9 shackle, the latter can slide along a pivot with the shaft 30 mounted on the frame of the locomotive 30 (fig. 1, 2), provided with a notch 27 for the roller 58 fastened at the crosshead, in order to turn the naps 86 to the nadap position roll 6 from the crosshead and stop the latter when it is in the forward dead position.

The crosshead roll 6-6j consists of two 7 parts b and 6j interconnected with a lock, the first of which, connecting the drawbar to the crosshead, is conical in its upper part and has lateral guides 8 for stiffening the connection during activation and coupling with a fist 9, the earring of which is provided with a key, which is inserted into the groove 8 of the roll 6, in order to eliminate the displacement of the latter.

In the second part of the roll b, for the wedge 19, reinforced by the stopper 80, there is a nest 10 (fig. 1, 2, 3, 4) and a nest located perpendicular to the letter for the bolt 11, and the tail part 12 of the roll is cut into sections sectors 46-46 (Fig. 1).

The lock 7 of the roll 6-6 is placed in a box 18 attached to the crosshead. consists of a hard nut 16 with a stopper 17 ,. connected by a lever 4 with movably mounted on a key without a gap on the shaft 15 by a drum 18 inserted on a tape thread

into the box 18, and from a hollow worm 14, loosely worn on a swivel booth and a driver, having a longitudinal groove, the same shaft 16 and provided with a key entering with a gap in the next-minute groove. The outer surface of the nut 16 is partially “packed with teeth for coupling them with the stonor 17 (Fig. I, 4) and with the hollow screw 14 (Fig. 1, 2). The swath 6 for excavation of the cs of the crosshead roll of the swath 6 is connected by a bolt 11 with a wedge 19 (Fig. 3, 4), linked by a lock 25 with the help of an oily buffer 21 moving in the axial direction, consisting of a housing 28 (Fig. 1) and a piston rod 23 with channel 24; in the case of pistons on the rear side there are holes 47 located around its circumference, designed for oil bypass. The lock 25 consists of a hook 45 of the switch 44 with a stopper 45 and can be controlled by a pull-out from the driver's booth. On the locomotive carcass to rotate the shaft 80 (Fig. 2), a steam cylinder 36 is installed, equipped with a steam distribution valve 55 (Figs. 5, 6, 7), the shank of which is connected by a lever actuator 37, 38, 40 and 4 / with a rotary cam 39, installed from the driver's booth, with the aim of turning the crane 55, with the help of an eccentric 42, fixed on the coupling axis of the locomotive.

The connection of the cylinder 36 to the shaft 30 is os1usche; tvat with the help of the lever 31 (Fig. 2) and the hook 32 of the piston rod 34, the end of which is guided by the sleeve of the bracket 55. The spring 29 serves to block the motion of the parallels 26 when the crosshead is turned off. To turn the driver off, the shaft 5 rotates, which having shifted the drum 8, deflects the lever 4 (Fig. 1), withdraws the stopper 1 from its own, and opens the stop nut 16. The key of the hollow screw 14 enters the groove of the shaft 15 and the screw 14 begins to rotate together with the nut, i, which opens with the shank of the cross-head roll 6-6. After the weakening of the latter, the oily buffer 21 is turned on, and the locks 35 are brought against the wedge 19 to engage with it at the rear extreme position of the piston, h. During the reverse, the subsequent closed wedge will begin to pull out the oil buffer 21, compressing the oil in the cylinder, which will leak through holes 47 for the piston rod, creating an increasing stroke

the piston braking effect of the clip 19. The latter is squeezed under the action of the buffer 21, will displace the Kreuzfk shaft 6 by its groove 6. Simultaneously with the introduction of the oil buffer 51, the cylinder 36 begins to act (Fig. 2), into which steam enters through valve 55 (Fig 5, 6, 7). At the head of the crosshead with the piston in the front extreme position, parallel 26 descends, freeing itself from engaging the crosshead along the shaft 28 in the notches 27 and pulling the roll 6 into channel 5 of the tide 2. Along the lowering of the parallel 26, the crosshead closes and stops the forward edge, whereby the entire motion system is turned off from the crosshead and moves along channel 5, provided on both sides and along all the lengths of its brackets 48, eliminating the loss of the ridge roll roll 6 ..

When the crosshead is switched on, the drive of the transmission lever 41 (Fig. 5, 6) is shifted, the eccentric switch 39 is lowered, which, under the action of the eccentric 42, moves away together with the levers 38 and 57, and creating a shift of the lever, sample the crane 55, blocking the channels (Fig. 7) . The steam from the boiler will go through the channel to the channel leading to the lower part of the cylinder 515, and from the upper part of the latter the steam will go through the channels from and to the atmosphere, i.e. the switch becomes on, tele.

A piston drawbar with a cross-head roll 6, lifted upwards, will go along the upper face of channel 5 and approach the forward extreme position) will approach the crosshead roll 6, and the support Steepness of the channel is designed to allow the drawbar to close with the crosshead.

The clip 19, resting against the rod 23 of the oily buffer 21, will drown the switch 44, which, sliding along the beveled face of the hook 43, deflects it and removes from the coupling with the wedge 19, ukreny the position of the switch 44 of the hook 43 by the stopper 45 (Fig. 3). The final fastening of the crosshead roll in is made with the help of a hollow screw 14, which, rotating the stop nut 16, will cause the shank 12 to disengage from cutting, and abutting the nut 16 at the same time, send the crosshead roll to the place and fix it. the stopper 17 of the nut 16 is turned on, relieving the pressure on the teeth and on the shaft 16.
