LUBRICATO R.

SPECIFICATION 'forming part ofV Letters Patent No. 354,353, dated December 14, 1836.

Application tiled August 21, 1886. Serial No. 211,651. (No model.)

.locomotive-engines, and is an improvement upon Letters Patent No. 320,703, dated June 23, 1885.

The invention' consists in certain special details of construction, some of which are not 'only adapted to the particular cups described,

but to others of the same general class.

In the drawings, Figure l represents the cup in section, with one ofthe sight-feed tubes in side elevation, and with the condensingcoil Fig. 2 is a side elevation of the cup, showing it attached to the locomotive-boiler, with the sight-feed tube upon one side in section, and with the pipe and valve leading to the cup and to the condensing coil also in section. Fig. 3 is a planv view of the cup with the coil removed. Fig. 4 is a detailed sectional view of the double check-valve.

The general form and operation of the oilcup, the sight-feed tubes, and the condensingcoil are substantiallyn the same as in my patent aforesaid, and need not therefore be particularly described herein.

The cup is shown atl, and is provided with sight-feed tubes l? P-oneupon each side-with passages 5 between the same and the cup, through which the oil passes. Acondensingcoil, J, surmounts the cup, being connected to the pipe M, so as to deliver the water of,` condensation into the cup to cause the oil to feed out through the sight-feed tubes and their pipe-connections to the parts to be lubricated. The other end of` this coil J is connected through an intermediate coupling, S, with a pipe,y K, in connection with the locomotiveboiler at any convenient point, and the live steam passes through the pipe coupling and coil and is condensed, as described in my said patent.

A valve, A, is arranged in the coupling S, at the point shown, so that the amount of steam fed to the coil may be regulated. The

connection between the coupling S and pipe K is by a union-joint, so that the whole lubrioator may be disconnected from the locomotive at this point without difculty. A branch, H, extends from the coupling S below the valveseat therein, and is provided likewise with a valve, B, and seat similar to the one in the coupling S. This branch pipe His provided with aT-connection, V, on its inner end, from each end of which extends a pipe, IV, leading to the sight-feed tube upon either side of the cup. The connection between the pipe and the space within the glass tube is formed by a passage, Y, through the castings N. It will thus be seen thatlive steam is admitted to the sight-feed tube through the connections described, thus tending to overcome the pressure through the pipes T T, which would otherwise tend to retard the iiow of oil.

The valve B is not entirely closed, but is left open sufliciently to allow enough steam through to the sight-feed tube to force the. oil and carry it to the parts to be lubricated.

In the lower iittings, D, of the sightfeed tube I form a chamber with inclined seats at either end, and place within this chamber a double-seated valve, It, with a small-sized aperture extending through the same, through which the oil and steam pass from the sightfeed tube to the pipes T T. The central portion of this valve It is of greater diameter than the ends, and is provided with an inclined face upon each side, adapted to the inclined seats in the fittings D. When the valve is acted upon by the steam coming through the pipes T T, it is forced upward against the upper seat, and only a small portion of the steam can enter to the space within the sight feed tube, in consequence of the small aperture through the said valve, thus preventing any interference with the perfect working of the cup, and when the steam is cut off from the pipes T T the effect of the vacuum thus formed is diminished to such an extent as to cause no appreciable difference in the flow of the oil.

Y vided at thejunction ofthe pipes T with the lower itting of the sight-feed tube, so that the steam from the pipe T may be shutoff in case the sight-feed tubes become broken, and to permit oftheir being replaced. The castings N N at the upper end of the sight-feed tube have valves C C, by which the iiow of oil through the tubes may be regulated. A valve, E, is used to shut off condensed water when it becomes necessary to refill the cup with oil.

It will be understoodthat while Ihave shown two sightfeed tubes upon one cup, two cups might be used instead with one sight-feed tube e upon each.

ing to the steam-supply and adapted to feed water of condensation to said reservoir, of sight-feed tubes, and checlrvalves having a seat upon each side thereof, and a central aperture, said valves being located between the sight feed-tubes and the parts to be lubricated, substantially as described. g

3. In combination, an oil-reservoir, a condensing-coil connected with the steam-supply, a Valve, A, arranged in the pipe leading thereto, abranch, V, pipes leading from said branch to sight-feed tubes, whereby the oil is forced through the connecting-pipes to the parts to be lubricated, a valve, B, in said branch to govern the supply of steam necessary for this purpose, and a doubleseated check-valve, R, with an aperture through the same, arranged in the lower fitting of the sightefeed tube, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
