Description

Patent No. 11561 describes a device for stopping the pistons and spools of a locomotive steam engine in that the engine crankshafts rigidly mounted on the axle are connected to their wheels only through the fist sleeves, which allow the locomotive to move with the regulator closed without compression in the cylinders. In the proposed device, which serves the same purpose, the axles carrying the drive cranks with their wheels are connected either by a washer mounted on the axle with a conical protrusion that fits into the corresponding conical recess on the frontal surface of the wheel washer, or by means attached to wheel hub latches abutting corresponding recesses on the axle.

In the drawing of FIG. 1, a schematic top view of the device is shown partially in section; FIG. 2 is a front view of the wheel washer and a cross-section of the axis;

FIG. 3-front view of the washer mounted on the axle; FIG. 4 is a front view of a modified device; FIG. 5-cross-section of the wheel of the modified device.

 The proposed device (Fig. 1) consists of a washer B, fixedly mounted on the hub of the wheel B of a locomotive, and a washer D, mounted on the A-axis, carrying the leading cranks. The washer B has a conical recess D (Fig. 2) on its frontal side above, which may include the protrusion of the washer D corresponding to the specified recess, whereby at the moment the specified protrusion is turned on, the crank coincides with the counterweight. The washer D may rotate in the ringing ring AND (fig. 3) connected by a fork lever O with a pull from the driver's booth. Axis A has, in part from its washer B up to the stop, a square cross section, and consists of two parts connected by a coupling M and a key Y.

While the projection E of the washer D is in the recess P of the washer B, the axis is -A. and wheel B is engaged and they rotate simultaneously. When a steam locomotive moves without steam, by moving lever O and washer D, the protrusion JS is taken out of: recess T, as a result of which axis -4. the crank will be at rest, while the wheels B will rotate without compression in the cylinders.

The described adaptation can be modified (Fig. 4, 5), and on the hub 1 of a wheel equipped with a flange b, two latches E are fastened, one of which is equipped with a pressure spring and connected to the other by a system of levers; on the A axis in this case there are cutouts corresponding to the latches and. When the A axis rotates with the open controller, one of the G cutouts rests on the corresponding latch E, which transmits pressure using a system of levers to the other latch, and the wheel rotates. When the regulator is closed, axis A will stop, while the wheel will rotate and will press on the latch JE, which will lift and retract the other latch using a lever system, causing the wheel to come out of the clutch with the axle and will rotate separately.

Subject patent.

1. Variation of the patent described in patent No. 11561, characterized in that the mechanism for bringing in tightly coupled cranks and traveling wheels consists of a washer B rigidly connected to the hub of the wheel B (fig. 1-3) having a conical recess G on its the frontal surface, and the washer D with the protrusion B meeting the specified recess, moved, for coupling it with the washer B, along the square part of the axis by means of the fork lever O.

2. The modification of the tool described in patent No. 11561 differs from that by using a mechanism for bringing into rigid communication the driving crank traveling wheels consisting of two E-latches attached to the hubs of wheels (Fig. 4, 5), through the corresponding cuts and on the axis, the rotational force imparted to it, during the operation of the Maplina, by the crank, one of which latches is provided with a compression spring, intended for transmission, with a lever system for pressing the second latch.
