PATENT OFFICE

The present invention relates to a lubricating device with a sight glass of the type at which the influx of lubricant continues when the glass breaks. She makes a difference differs from the previous design in that when the sight glass breaks, the path, the the OeI takes, remains the same as before. The mode of operation of the new device is in such a way that a valve mounted opposite the inspection opening in the oil passage channel if the sight glass is broken by the steam on the sight glass opening of the oil passage is brought.

A device of the new type is shown in the accompanying drawing, but is The invention is not limited to the application in the illustrated lubricating device.

Fig. Ι is a side view of the new lubricating device.

Fig. 2 is a vertical section.

FIG. 3 is a section taken in the direction of line 3-3 of FIG. 1.

The lubricating housing A is provided with a screw lock A ¹ , which can be removed when fresh lubricant is introduced. At the bottom there is a valve or bolt A ^ through which the rainwater can be drained.

A channel B , which is equipped with a nozzle C , is arranged in a thickened wall A ^{a of} the housing A. In the upper part of the channel B is closed by a screw threaded plug ^B1.

The nozzle C serves as an inlet element for the oil which comes from the housing A through a tube D. The amount of oil is regulated by a valve E with a handwheel E ¹ , the screw-threaded spindle of which is screwed into an insert E ' ² . Near the upper part of the channel B there is arranged an outlet F which communicates with an outlet F ² through a channel F ¹ . The latter is suitably connected with the parts to be lubricated. The arrangement described so far forms the actual lubricating device. This is not new, nor is the present invention limited to connection with this particular arrangement.

A plug G with a hole G ^{1 is} screwed into an opening in the wall ^{A a} , into which a disk G ² made of glass or other transparent material is inserted. The disk lies between packing rings G ³ and is secured by a screw ^{ring G 4.}

The disk G ² forms a window through which the oil flow from the line C to the outlet line F can be seen. The attachment of the window does not form the subject of the invention.

In the opposite wall of the channel, a valve H with a guide H ^{1 is} mounted in a bore B ^3. The valve is located in an extension B ' ² .

The spindle H ¹ advantageously does not have a circular cross-section, but is designed with a longitudinal groove or a channel JT ^{2 in this} way.

Claims (2)

Connection enables the steam to pass to the rear of the valve through a channel J which is in communication with channel F1. The wall A3 is provided with a valve seat G5 at the opening G1, on which the valve rests if the sight glass G2 breaks, thereby closing the opening G '. The valve is driven forward by the pressure in the line / and pulled onto the seat G5 by the escaping steam and water. The steam enters the lubricating device in a known manner through a channel K 'into which a valve L is inserted. The latter can be set using a handwheel L1. When the steam has passed the valve L, it passes through the channel K1 into a bore K2 which, in a likewise known manner, directs the steam to the lower part of the housing A of the lubricating device. From the space L2, in which the valve works and with which the channel K1 is connected, another channel M leads to the oil outlet F2 in such a way that, when the valve L is opened, the oil in the channel F1 and the oil outlet Outlet F2 is driven out by the injector-like effect of the steam flowing through the channel F. The oil in the housing A of the lubricator is forced by the steam from the tube K to the upper part of the lubricator and from here passes through the tube D to the nozzle C, its flow being regulated by the valve E. This inflow is not interrupted or not changed if the valve H should also be pressed onto its seat G5 as a result of the break in the window G2. The upper part of the nozzle C lies somewhat below the path of the valve H, so that it is prevented when it has to cross the line B. If the glass pane breaks, the valve H can be pushed back after the steam has been shut off, and the broken pane G2 with its packing rings G3 will be taken out after removing the stopper G4, and the valve pushed back by doing anything suitable Tool passes through the hole G1. A new window can then be introduced and the plug G4 and the packing rings G3 replaced, whereupon the lubricating device can come into effect again. Obviously, the lubricator can work uninterruptedly and for a long time if desired, even if the glass is broken and the valve H is pressed onto its seat G5. Under these circumstances a metal disk can also take the place of the window G2 in order to prevent the valve H from being pushed back by any accident. Advantageously, the cutout for the disk is approximately the same size as an ordinary coin, so that if necessary a certain coin can be used in place of the broken glass. Patent-A ν Proverbs: 1. Lubricator in which when breaking the sight glass allows steam, water and lubricating oil to escape automatically closing valve is prevented, characterized in that the sight glass and Valve are arranged in the lubrication line in such a way that the valve opens the opening in which the sight glass breaks Sight glass sits, closed, without blocking the normal path for the lubricant. 2. Lubricating device according to claim ι, characterized in that the inspection opening G ^{1 is provided} on its inside with a valve seat G ⁵ , on which the valve H mounted in the opposite wall of the lubrication channel B under the influence of the steam acting on its rear side when breaking of the sight glass G ² touches down. For this purpose ι sheet of drawings.
