| Abstract:
This invention relates to means, operating frictionally for locking in adjusted position, valves of such lubricators which feed by gravity and are used for oiling journals and bearings, also for such valves which are used in connection with devices for supplying oil or other fluids to spray nozzles, jets etc. It constitutes an improvement on the device shown in Patent No. 408,927 issued to me on August 13th, 1889. The object of this present invention is to produce a compact, efficient and cheap device for the purpose named, and whereby the rate of discharge of oil may be easily and quickly adjusted and whereby thereafter the regulating parts (valve) may be securely held in adjusted position against accidental disturbance while the lubricator is in use. The invention consists of the particular construction and arrangement of parts as shown and described and whereby the construction is greatly simplified by reducing the number of parts required, to the smallest possible number consistent with efficiency which is accomplished by using existing structural parts of the lubricator for such purpose.
Claim:
In a lubricator, the combination of an oil-retainer consisting of a shell and a top and bottom, a hollow tie-post seated in the bottom by means of a screw-connection and extending through shell and top and above this latter where it is diametrically increased to form an integral shoulder which, by bearing against the top, serves to hold the parts of the oil-retainer together, there being also vertical serrations on the outside of the tie-post above this shoulder and a valve-seated outlet near its lower end, a carrier adjustably supported within the upper part of the tie-post, a valve for the seat mentioned which has a stem extending upwardly through the lower part of the tie-post, and through and above the carrier in which latter it is supported so as to have a sliding adjustment with reference to the valve-seat, a handle at 11 the upper end of this stem to manipulate the valve for the purpose of opening or closing the outlet and to control passage of oil therethrough and a combined adjusting and locking lever rigidly connected to the upper end of the carrier and shaped to yieldingly engage the serrations in the tie-post and whereby the carrier may be adjusted to regulate the rate of flow through the open outlet and at the same time locked in its adjusted position. |
