SPECIFICATION forming part of yLetters Patent No. 552,194, dated December 31, 1895.
Application nea August 14,1894. Seriana 520,322. (No moda To a/ZZ whom it may concern.-
Be it known that I, JOHN W. MORGAN, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Pipe-Oiler, of which the following is a specification.
My invention relates to lubricators, and it has for its obj ect to provide a device adapted for use in oiling machinery at a plurality of points from a common tank or reservoir by means of feed-tubes communicating with the tank, and, furthermore, to provide an improved feed-nozzle so constructed as to facilitate its application to the feed-tube at any desired point, whereby the tube may be tapped for a nozzle and the nozzle arranged in operative position with the minimum loss of time.
Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.
In the drawings, Figure lis a vertical section of a tank, feed-pipe and nozzle constructed in accordance with my invention. Fig. 2 is a detail vertical section of the lower member of the feed-nozzle, including the valve-seat and the sight-tube; Fig. 3 is a detail side view of the strainer.
Similar letters of reference indicate corresponding parts in all the figures of the drawings.
In an apparatus embodying my invention, A represents a tank in communication with a main feed-tube B having a stop-cock C, and within the tank is arranged a strainerD having1 a depending sleeve E, which surrounds the projecting extremity of the feed-tube to prevent lint and sediment from entering the feed-tube. Communicating with the tank at its bottom is a trap F and mounted upon this trap is a gage G to show the quantity of oil in the tank. The trap is adapted to catch any water which may be contained in the oil, and the water may be drawn Off by removing the screw-plug H without interfering with the operation of the oiler. Communicating with this main feed-tube may be any desired number of branch feed-tubes J, suitable couplings I being arranged at the points of intersection. The outer extremities of the branch feed-tubes are provided with removable closures N.
The feed-tube maybe tapped at any desired point or points for the application of nozzles, and the nozzle embodying my invention comprises upper and lower members P and S, respectively, each of which is provided with a threaded tip t adapted to be threaded in registering perforations in the upper and lower sides of the tube. The tip of the upper member is formed integral with a guide P', in which is mounted a tubular valve-stem O. Said valve-stem is preferably threaded in the guide, and a stuffing-box P2 is arranged upon the guide to prevent leakage. The stem terminates at its upper end in a hand-wheel P3, and a removable plug Q is secured in the upper end of the bore of the stem to close the same. The tip t of the lower member is provided with a valve-seat S to receive the valve which is formed by the rounded or ground lower extremity of the valve-stem, and said tip forms a part of a tubular conductor S2 having lateral iianges S3. Said lateral flanges are secured in contact with the upper end of a sight-tube T by means of a screw-cap S4, said sight-tube being provided with lateral openings V closed by a transparent guardU arranged within the tube. The sight-tube is provided at its lower end with a communicating outlet-nipple S5.
From the above description it will be seen that the improved nozzle may be applied to a feed-tube by boring and threading registering openings in the upper and lower sides of said tube and screwing the tips tof the members of the nozzle thereinto, thereby facilitating the application of the nozzle and enabling the Same to be accomplished with the minimum` loss of time in operating machinery. The tubular conductor or dropper S2, which conveys the lubricant from the feed-tube whe'n the valve is unseated, has its bore ar- .ranged in vertical alignment with the bore of IOO ple S5 to remove any accumulations of dirt or sediment therein and secure the proper flow of oil.
A further advantage of the sectional construction of the improved lubricator resides in the fact that the valve-stem, which extends transversely across the bore of the oil-tube, is of such diameter as to avoid interference with the iiow of oil past the lubricator. Hence a plurality of lubricators embodying my invention may be applied to the same tube without so obstructing the flow of oil as to prevent those near the end of the line from receiving sufficient oil to preserve a constant How.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacriiicin g any of the advantages of this invention.
Having described my invention, what I claim is- In a lubricating device, the combination with a feed tube adapted to communicate with an oil reservoir or tank, of a nozzle comprising independent upper and lower menibers arranged in axial alignment, respectively7 above and below the feed tube and provided with tips threaded in registering` openings in the upper and lower sides thereof, the lower member of the nozzle having a conductor or dropper in communication with the feed tube and provided contiguous to its upper end with a valve-seat, and the upper meinber of the nozzle having an axially movable valve-stem terminating at its lower end in a valve adapted to fit said seat, whereby in order to attach the nozzle to the feed tube aligned openings are formed in the upper and lower sides thereof and the tips of the nozzlemembers are screwed in said openings, the valve-stem being of such diameter as to extend transversely through the tube without interfering with the iiow of oil past the lubricator, substantially as specified.
In testimony that l claim the foregoing as my own I haveV hereto afiXed my signature in the presence of two witnesses.
