SU43921A1 - A device for lubrication of rounded rails - Google Patents

Description

Gears for lubricating rails on roundings, releasing lubricant from a reservoir onto rails through drain valves opened by an electromagnet excited by centrifugal force when a car enters a curvature, are generally known. In the proposed such device to start the current in the electromagnet is a switch made in the form of a tube placed horizontally in the car, across it, and partially filled with mercury. Under the action of centrifugal force, mercury is thrown to one end of the tube, where its level rises and closes the upper contact that exists there, which lets current into the electromagnet, the measles of which is connected to the drain valve plug.

The drawing schematically depicts FIG. 1-location of the device on the tank; FIG. 2 is a front view of the device itself; FIG. 3 is a side view thereof and FIG. 4 view from above.

A tank / (FIG. 1) with a lubricant fluid is installed in the car; The pipes 2, 2 leading from it to the rails are closed by cork taps 3. Above the tank is the adaptation mechanism itself, comprising primarily an electromagnet 4 (Fig. 3 and 4), which is kinematically connected with the plugs of taps 5. Electro (338 )

The magnet is activated by the switch 5, which is a tube filled in part with mercury. This tube, divided to avoid rolls of mercury on the side of the transverse wall into two parts, is installed horizontally and perpendicularly to the longitudinal axis of the car. One wire of the circuit, which the electromagnet enters, is inserted into the tube from the bottom, and the other wire is upward of the tube, so that at the normal position the level of mercury does not touch it.

When a car arrives at rounding, mercury is thrown to one end of the tube under the action of centrifugal force, fills it to the top there and, touching the top contact, closes the circuit. The electromagnet is energized, attracts measles b and it acts on taps 3, opening their plugs, through which grease will pass through pipes 2 to the rails all the time, along (; and the car goes on rounding. When the car leaves, it goes to direct mercury pours, takes the normal level, the circuit opens, the electromagnet’s measles drops and the crane plugs, under the action of their springs, close the taps.

In order for mercury not to close the circuit in case of random side shocks when the car goes along a straight path, there are special separate for each half of the tube 5 current interrupters 8, suspended in the form of tanks on axes 7 and able to be pumped out only in one direction. With a lateral push, the breaker S of the respective side will pump out the rod 9 at its top, act on the wires, interrupt the current and the device will not act. With a smooth, jerking entry of the car for rounding up due to sufficient friction in axle x 7, this will not happen, and the device will begin to work smoothly.

The subject matter of the invention.

Claims (3)

1. A device for lubricating the rails on roundings with fluid enclosed in a tank with drain valves opened by an electromagnet activated by centrifugal force, characterized in that To close the circuit, there is a switch 5, made in the form of a tube containing a certain amount of mercury perpendicular to the longitudinal axis of the car, the level of which, when I pass the car along the curve, under I influence of centrifugal force, rises at either end. I 2. The form of the device according to claim 1, characterized in that, in the prevention of its action due to strong side shocks, we used contact switches 8, 8. 3. The shape of the device according to claim 2, characterized in that the hanging of the miniature interrupters on the swing axis 7 is made with a density that allows the breakers to swing only when there is side shocks on the straight path and not allowing them to swing at a smooth entrance of the car to round.
