SPECIFICATION forming part of Letters Patent No. 379,243, datedidarch 13, 1888. ,Application filed May 16, 1886. Serial No. 203,328. (No model.)

To @ZZ whom it may concern:

Be it known that l, JAMES POWELL, a citizen of the United States, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to those devices in which oil or a similar iiuid lubricant floats on condensed water that gradually collects in the bottom of a reservoir or fount.

The first part of my improvements consists in locating an enlarged distributing-chamber in the base of the fount, but separate from the latter, the object of this chamber being to prevent au accumulation of oil and water within the sight-tube,77 as hereinafter more fully described.

The second part of my invention consists in providing the upper portion of the reservoir with a depending iiange that serves as a trap or barrier t0 prevent condensed water or steam entering the lateral channel leading to the sight-tube, as hereinafter more fully described.

The third part of my invention consists in chambering the socket at the upper end of the sight-tube for the purpose of preventing con dense-water running down the nipple that affords the drop-teeth7 as hereinafter more fully described.

In the annexed drawings, Figure l is an axial section of a lubricator embodying my improvements, the index or gage tube and its accessories being shown in elevation. Fig. 2 is a vertical section of the fount and its integral channels and sockets. Fig. 3 is an enlarged horizontal section through the depending ilange of the reservoir. Fig. 4 shows a valved attachment that may be applied to the lubricator.

The fonnt, reservoir, or oil-chamber A, which is usually cylindrical, has a threaded neck, a, into which is screwed the lling-cap B, having a crank or hand wheel, b, secured thereto. This filling-cap is made considerably longer than usual, and is chambered at C, the lower end of said chamber being opento aft'ord cornrnunication with the fount.

D is an ordinary condensing-tube proceeding from the distributingchamber P and eX- teuding up almost to the top of the hollow tilling-plug B C. Cast with the t'ount Aare four lateral branches orchauuels, E E F F', terminating with suitable sockets, c eff, to admit the index or gage tube G and sight-tube H. These sockets or holders are properly screwthreaded to receive ordinary stuffing-boxes, I, that prevent leakage around said tubes. The lower socket, e', ofv index-tube G has a draincock, J, coupled thereto, while the upper' socket, e, of said tube has a screw-threaded plug, K, engaged therewith. L isa precisely similar plug screwed into the lower socket, f', of the sight-tube, the inner prolongation of said plug being ported at Z to permit a free passage of'oil. The upper socket, f, of the sight-tube has the feed-nipple M depending therefroni,which nipple may either be integral with said socket or it may be fastened to the same. Furthermore, the inner side of this socket f is chambered or counterbored at N, to prevent the condensed vapor that forms on the inner side of tube H collecting on the nipple M and mixing with the oil discharged from the latter; consequently there will be no danger of an engineer mistaking a drop of condense-water for oil.

Depending from the top of reservoirA isa flange or curb, O, whose lower edge is some distance below the lateral channel F, in order that said iiange may serve as a trap or barrier to prevent steam or water of condensation entering said channel.

The lower channel, F', communicates with a distributing-chamber, l?, located under the reservoir A, but being separate and distinct from the same, said chamber being sufficiently capacious to admita free circulation of steam, water, and oil therein. As a result of this circulation, said chamber and its connected sight-tube H can never become choked up with oil and water, which is a frequent annoyance where such a chamber is not used. This chamber has a threaded neck, p, to which a connecting-pipe, R, can be coupled, said pipe being adapted for attachment to any part of an engine; or the valved attachment S seen in Fig. 4 can be coupled to the chamber I), if desired.

T is a valve that regulates the discharge of v the drop-feed at nipple M,

From the above description it is apparent IOO that the oil floating upon the condensed water can ascend within the hollow cap B C, thus adding considerably to the head or pressure of the fluid and without enlarging the height of the reservoir A, which enlargement would render the lubricator heavy and unsightly and materially increase the cost of manufacture. By casting the lateral branches with the fount or reservoir, the sockets of said branches are rigidly in line with the axis of the iount, thereby saving the labor and annoyances incidental to the ordinary method of coupling these members together.

I claim as my invention l. The combination, in a lubricator, of the reservoir A, having at its base an enlarged distributing-chamber, l?, of practically the same diameter' as said reservoir. the steam-inlet R, entering the center of said chamber, and a side passage, F', leading from the latter to the bottom of the sight-feed tube, as herein del scribed.

2. A lubricator-reservoir having a lateral channel communicating with the top of the sight-feed tube, and a pendent iiange opposite the entrance of said channel, for the purpose described.

3. A lubricator-reservoir having a socket that receives the top of the sightfeed tube, the upper end of said socket sloping from its center downwardly and outwardly, for the purpose described.

4. The combination, in a lubricator, of reservoir A a., chambered lling cap B C, condensingtube D, lateral channels E E F F', sockets e eff, indexglass G, sight-feed glass H, stufling-boxes I I I I, drain-cock J, ported screwplugs K L Z, drop-feed nipple M, and distributing-chamber Roue ofthe upper channels, F, being provided with the depending iiange O, as herein described.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES POVELL.
