WILLIAM F. MATTFS AND JOHN F. LEWIS, OF SORANTON, PENNSYLVANIA, ASSIGNORS rro WILLIAM F. MATTFS, TRUSTEE, OF SAME FLAOF.
LUBRICATOR.
` SPECIFICATION forming part of Letters Patent 1Y0. 389.755, dated September 18, 1888.
' To @ZZ whom it may concern,.-
Be it known that we, WILLIAM F. MATTEs and JOHN F. LEWIS, citizens of the United States, residing at Scranton, in the county of Lackawanna and State Of Pennsylvania, have invented certain new and useful Improvements in Lubricators; and we do declare the following to bea full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the acconr panying drawings, and tO the letters and iigures of reference marked thereon, which form a part of this specification.
This invention relates to lubricators of that class in which the lubricant is displaced by waterof condensation and is fed through a sighttube filled with steam.
'The object of the invention is to improve this class of devices generally' and to increase their efficiency and render more certain the operation of the same.
The improvement consists of the peculiar construction and combination of the parts, which will be more fully described hereinafter, and pointed out in the claims.
In the drawings, Figure 1 isa front view of a lubricator of my invention; Fig. 2, a vertical section of the lubricator on the line X X of Fig. 1, showing the fitting and the glass tube in full lines; Fig. 3, a vertical section of the tting and a part of the oil-reservoir and glass tube on the line X X of Fig. 1 on an enlarged scale; Fig. 4, a detail view of the valveoperating stem on an enlarged scale; Fig. 5, a detail view of the hanger or rod provided with the valve; Fig. 6, a crosssection of the rod on the line Y Y of Fig. 5; Fig. 7, a top plan view of the collar; and Fig. 8, a sectional View of a fitting, showing a modification.
R is the oil-reservoir, which is filled through a hole in the top, shown closed by the plug P.
H is a shank or socket for attachment to the steam-supply pipe or chest.
X is a steam-passage with open vcommunication to the glass tube Gand with the tube T, by means of which steam is introduced to the top of the cup. An interior tube, F, is the feed-tube, which conveys oil to the fitting E, which is the regulating valve case.
I is a hand-wheel.
J is the yoke stem, working through an ordinary stuiingbox, J3.
Application filed March 7, 1888. Serial No. 266,419. (No model.)Y
J is a screw, and J a yoke formed with or fastened to the stem J.
F is the regulatingvalve, suspended by the rod or hanger U U, the latter being guided by the yoke J and upheld by the collar N, which is fastened Io the rod by a pin, n, passing through an Opening, n', in the said collar and fitting in the notch or depression u in the side of the rod U. A tube-shaped extension, e, of the fitting E within the glass G conveys the oil to and forms a seat for the valve F. As the collar N is free to rise within thelimits imposed by the yoke J, the valve, when open, may be automatically closed by a pressure of steam in the glass tubeG unlessit is balanced by a nearly equal pressure above the valve. When the pressures are balanced,the collar will rest, as shown, upon the lower part of the yoke, and the valve may be closed by means of the hand-wheel Ioperating the screw J'. At U the valve-rod is formed with three sides, the corners of which serve the double purpose of centering the valve in the tube e and of reaming theholeclear of any obstruction whenever the hand-wheel I is turned. To insure that the valve-rod shall always revolve when the hand-wheel is turned, the collarN is made flat on the side next to the vertical part of the yoke J.
In Fig. 2 is shown a cap or hood, C, suitably ysupported on the end of the tube F, so as to leave a space between it and the end of the tube for the escape of the lubricant. This cap Or hood C is sufiiciently large to shed the water of condensation that accumulates and drops from the plug P and prevent it from entering the said tube with the lubricant. A
sInall hole, h, is drilled through the plug P a little below the joint between the plug and the top of the bushing P', that is screwed in the top of the cup, which serves two useful purposes: First, if a little steampressure should remain in the cup when the plug is screwed out it can escape through the hole without annoyance to the operator; second, it prevents the imprisonment of air within the plug when the latter is replaced, and thereby reduces its displacement and prevents it from forcing too much oil up into the steam-tube T', which would cause siphoning.
The operation of the cup after it has been attached by means of the shank H to the main steam-pipe is as follows: The passage K, the
steam-tube T, and the glass tube G fill with steam. If the valveV,whieh is located in the tube T, is closed, the pressure in the glass tube will not be balanced by a pressure in the oilreservoir R, and the regulating-valve F will be automatically forced against its seat. The plug I is then withdrawn and the cup lled with oil or any other lubricant which is fluid at the temperature of steam, and which will float upon water. The plug is then replaced and the valve V opened, which admits steam to the interior of the cup and thus balances the pressure existing in the glass tube G,with the result that the valve F opens automatically and the oil at once begins to flow into the glass tube and through the passage K into the main steanrpipc. As the oil is withdrawn from the cup its place is supplied by the water formed by the condensation of the entering steam. The water will accumulate in the bottom of the cup, and will float the oil up until the supply of the latter is exhausted. The oil will feed, drop bydrop, or faster, through the glass tube, according to the position given by the operator to the regulating-valve F". To refill the cup the operator will first close the steam-valve V, then open the drain-cock D, withdraw the plug I), close the drain-cock as soon as the water is drawn off, refill the cup with oil, replace the plug, and open the valve V.
We are aware that oil-cups have been patented in which oil is fed through a glass tube filled with live steam by means of a drip-tube having a regulating-valve at the top, and do not claim such, broadlygbut we claim the combination most particularly shown in Fig. 3, with the valve placed at the bottom of the extension-tube, thus excluding steam from the tube, and forming the drop upon the exterior of a suitably-shaped valve instead of upon the interior surface of the tube, .as novel and essential to a satisfactory operation. Vhere steam has access to the interior of the tube interior condensation results, and the drippings are part oil and part water, and apt to be delivered with an irregular pulsating action, which is entirely overcome by our device.
In some cases the yoke J, the collar N, and the rod or hanger U U may be dispensed with, and the stem J will be continued down through the fitting E and its tubular extension e and terminate in the valve F, which is seated within the said tube e, the inner end being contracted, as shown in Fig. 5. In either case the oil will collect on the end of the valve F, where it will be plainly exposed tofview through the glass tube G, through which it will descend to the passage K and from thence to the parts to be lubricated.
The lower end of the case is externally threaded, and between this threaded portion E and the tube c an annular groove, c', is formed, which receives the end of the glass tube. The cap El, screwed on the threaded end E', receives packing material and forms a tight joint between the tube G and the litting E.
The steainpassage K has a threaded opening in its lower end inline with the glass tube G, which is closed by the plug K. By removing the plug K the passage K and the tube G can be cleaned out.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, isn
l. In a steam-condensing displaeemcntlubricator, the combination, with the oil-reser voir having a steam-ingress at its top and a steam-passage at its bottom, ofthe fitting communica-ting with the upper portion of thereservoir and having a tubular extension, the glass tube connecting the fitting with thesaid steam-passage, and the valve arranged to close the lower end of the said tubular extension and having its stem extending through and working in the said extension, substantially as and for the purpose described.
2. The combination, with the oil-reservoir and the fitting communicating with the upper portion of the oil-reservoir and having a tubular extension, of the valve for closing the lower end of the said tubular extension and the valve-stem screwed in the aforesaid fitting, substantially as set forth.
