The present lubricating vessel continuously guides the machine parts to be lubricated a certain small amount of the lubricant when warming up the parts concerned however, it automatically leads to an increased influx of the lubricant to prevent further heating of the rubbing parts.

α denotes the glass jacket of the lubricant vessel, which is tightly inserted into the nozzle b. The connecting piece b is provided with a thread in order to be screwed into a corresponding bore in the bearing cap, the cross head and the like. An almost airtight closing lid c covers the top of the vessel, c ^{1 is used} to introduce the lubricant. The tube d , which is partially filled with mercury and bears an enlarged capsule d ^x at the bottom, is freely displaceable in a central longitudinal bore c ^{2 of} the cover c and a similar b ^{l of} the connection b. rests on the bearing pin, e is the piston carried by the mercury column, sliding with little friction in d , but as thinly as possible, the threaded extension e ^{1 of} which carries the valve f , with its seat in the cover c. The through bore of the connection piece is b square, so that a sufficient passage cross-section is created for the lubricant, while at the same time d the pipe a good guidance is, Fig. 2. g The tube which is pierced the lubrication container longitudinally through sets and multiple, here has only the purpose of securing the connection between cover c and nozzle b.

For the purpose of attaching the lubricating vessel to the bearing and the like, the tube d is held in the raised position by a clamping screw d ² , after loosening this screw it lowers and rests with the capsule d ¹ on the bearing pin. With the help of the thread on e ^l , the valve f is adjusted to the piston e in such a way that it rests tightly on its seat. As long as the camp is in normal condition. can only be one whole in the lubricant reservoir; A small amount of air can enter and therefore only the material necessary for lubrication emerges from it. However, if the bearing heats up, the heat is also transferred to the column of liquid enclosed in d ¹ d; it expands, the piston rises, and valve f is opened. In the same abundant measure as air now enters the vessel, the lubricant also flows out of it.

In order to ensure the automatic closing of the valve, the same could be loaded accordingly. In addition, the device described can also be modified in such a way that the piston e does not directly carry the valve /, but rather opens it by means of one or more intermediate members.

In the embodiment of the lubricant vessel shown in FIG. 3, when the rubbing machine parts are heated, the lubricant is not only allowed to air but also by enlarging an otherwise small passage space for the outflows, using the tube g and one in the same sliding piston valve carried by the piston e. The tube g has the longitudinal

slots g ¹ g ¹ . The lubricant must enter the pipe through these slots in order to get to the exit point. In the normal state, the piston valve h , which is adjustable to e, is located below the slots g ¹ g ^l , and the lubricant is forced to seep through the space between h and g , while the air access to the lubricant container is restricted and therefore only one release of lubricant is low. If, however, the bearing heats up, air is let into the vessel in the manner described above by lifting the valve and at the same time the slots g ¹ g ¹ in g through the slide h, depending on the degree of heating of the bearing, are more or less released, so that the lubricant below the piston valve h can enter the pipe g unhindered and flow out. Pa te ν τ claims: i. A lubricating vessel, in which, when the parts to be lubricated warm up, the lubricant is supplied to them to a greater extent by the fact that the column of liquid enclosed in a tube dd ¹ resting on the bearing journal expands as a result of the warming and thereby lifts a piston e , its extension by opening a valve / allowing air to enter the otherwise almost airtight vessel, so that the lubricant can escape in larger quantities. 2. An embodiment of the under i. marked lubricator. in which the extension of the piston e on top of the air valve / still carries a piston slide h , which slides in a tube g which penetrates the lubricant vessel in the longitudinal direction and is provided with slots g ^l g ¹ and these slots usually close at the bottom, so that the lubricant In order to get to the outlet point between the piston valve h and the pipe wall g must seep through, while when the piston e moves upwards due to the heating of the machine parts, the slits g ¹ g ^{l are} more or less released by the piston valve h, so that Lubricant can escape unhindered in large quantities.
