SU841A1 - Adaptation to locomotive reverse - Google Patents

Description

with valve E, which, when turning shaft C, connects one of the tubes M or N to the inlet tube L, and the other to the atmosphere through 7. In the middle position, both tubes M and L communicate with the atmosphere through / and the inlet tube L is closed. The shaft C rotates in both directions at the same angle and remains in this position until clutch A comes to the desired position; it then returns by turning knob D to the middle position; so that clutch A can be moved with the screw S when working manually and at the same time only slide along it, under the action of the steam or air apparatus, a side bearing is inserted into the clutch box - a half-nut B, which has a screw cut from below, on some part of the circle and in the longitudinal direction is a notch, the upper outline of which corresponds to the outline of the notch of the bar C. This notch is of such dimensions that when the bar is rotated C is the half-nut, the half of the nut freely rises up, and the difference is in the diameters of the center of the notch s is the height of lifting zubpov (or even slightly more) required for a full pullout. From above, the spindle presses on the spindle G with the spring F. The oiler H serves as a stop for the spring / and in case of a breakdown it can be screwed up to hard pressing on the spindle G, which prevents an inadvertent release of the half-nut and provides manual operation.

O represents a steam or air cylinder; G is an oil or, in general, hydraulic buffer — a cataract that serves for smooth movement. Gate Q is used to change the speed.

the flow of fluid from one side of the piston to the other than the speed of operation varies. Both pistons are worn on a common rod, which is connected to the rocker lever T with the B earrings. On those locomotives where there is no rocker lever and transferring gear, it engages the fingers of coupling A directly, the additional lever device is necessary to reduce the stroke of pistons O and P.

Thus, under the action of an air or steam apparatus, the entire work of the driver is reduced to turning the handle D to the left or to the right and returning it to the middle position as soon as clutch A has become on the required tooth. When working manually, it is necessary either to move the pistons P and O together with the lever T or to disconnect the JL

SUBJECT OF THE PATENT.

The adaptation to a locomotive reverse, characterized by the use of a rotating shaft C installed parallel to the screw, with a recess in the upper part of its full length, reducing the vertical diameter by the height of the half-nut 1} for the screw S reverse sliding into the screw-covering coupling A and a spring / pressed against the screw and mounted on the spindle G of the coupling, which shaft C is provided with a handle D for turning in one direction or the other and connected to the plug Jf of the valve controlling the inlet or outlet of steam or air through tubes M or / V at one end or another of the servomotor O with the oil cataract P and the piston connected to the lever T of the reverse.
