LU BRICATOR.

SPECIFICATION forming part of Letters Patent No. 442,322, dated December 9, 1890.

Application filed August 5,1890. Serial No. 361,091. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM JAMES, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

My invention relates to single-connected sight-feed lubricators, by single'connected intending a lubricator in which the inlet for the steam and the outlet for the oil are in one and the same shank by which the lubricator is connected to the part to be lubricated. In lubricators which have, as these do, a common passage for the steam and the oil more or less of the latter is carried into the condenser by the force of the inrushing steam. The oil thus carried does not of course reach theparts to be lubricated, and while it may not be absolutely wasted, still it does not perform properly its intended functions. To obviate this difticultyl provide the lubricator with a connection shank. having a separate inlet-passage for the steam and a separate outlet-passage for the oil, in combination with other improvements which tend to make the lubricator more effective and complete in its functions and operations.

The nature of my improvements can best be explained and understood by reference to the accompanying drawings, in whicl1- Figure 1 is a vertical section of the lubricator on line I I of Fig. 3. Fig. 2 is a vertical central section of the same on line 2 2, Fig. 3. Fig. 3 is a horizontal cross-section of the oil-chamber on line 3 3, Fig. 1, omitting the interior pipes of this chamber and the sight-feed connections. Fig. I is a section on line at 4:, Fig. 1.

Ais the oil-chamber, provided with the usual filler B for filling the receptacle with oil, and with a drain-cock C for the purpose of drawing off the water of condensation after the oil has been fed out. On top of the oil-chamber is screwed the condenser I), provided with a pipe E to lead the water from the condenser to the bottom of the receptacle. The bottom of this pipe is seated for the usual water valve F.

G is the oil-pipe, which leads the oil from the top of the oil-chamber down into the passage H, leading to the sight-glass I, which is filled with water, through which the oil-drops float upward until they pass through passages K and L into the connection or delivery shank M. This shank, which is shown as being castin one with the main body of the lubricator, is intended to screw into the main steam-pipe cylinder or steam-box of the steamengine by means of the externally-threaded neck N. It is divided into two parts by means of a cross-partition O, which is cast in one with it, one of the parts I forming the inletpassage for the steam, the other part B forming the outlet-passage for the oil. Shank M is furthermore provided with a neck S, connecting the steam-pipe T to it. This pipe at its upper end screws into the condenser at some distance below the top of the latter, thus leaving an air space or chamber in the condenser about the point where the steam enters the chamber. The pipe at its upper end projects some distance into the condenser and is provided with a number of holes a to form a steam-spray, thus facilitating condensation.

The operation of the lubricator is as follows: Steam being admitted, it passes through passage 1 and pipe T into the condenser. The water of condensation passes down pipe E and, if valve F is opened, into chamber A, and the oil displaced by the water passes down pipe G, through passage I-I, glass I, and through passages l\', L, and 1t into the main steam-pipe cylinder or steam-box.

In this luhricator the steanrconnection with the condenser is simplified, rapid condensation of the steam without danger of plug ging is secured, and the conveying of oil to the condenser in any material quantity is wholly avoided.

In conclusion I state that I am aware of Patents Nos.18l,l26, 191,425, and 202,736, and claim nothing that is disclosed in the same.

Having described my improvements, what I claim, and desire to secure by Letters Patent, 1s

A single-connection lubricator comprising, in combination, the following elements: the single-connection shank M, divided by crosspartition 0 into passages P R, separate and distinct from each other, the external stezunpassage R, substantially as and for the purpipe T, leading from passage P into the conposes hereinbefore set forth. 1c denser at a point below its top, and provided In testimony whereof I have hereunto set at its discharge end with a rose or series of my hand this 4th day of August, 1890.
