UNITED STATES DAVID MOREHOUSE, OF ST. ELMO, ILLINOIS.

LUBRICATOR FOR ENGINE-VALVES.

Specification of Letters Patent.

:atented June 12, 1906.

Application filed October 13, 1905. Serial No. 282,656.

To all whom, it may concern:

Be it known that I, DAVID MOREHOUSE, a citizen of the United States, residing at St. Elmo, in the county of Fayette and State of Illinois, have invented new and useful Improvements in Lubricators for Engine- Valves, of which the following is a specification.

This invention is a lubricating device for the slide-valves of steam or other engines, and has for its object to provide improved and simple means for lubricating the valve and cylinder, the lubrication being automatic with the movement of the valve.

In the accompanying drawings, Figure 1 is a plan view of the valve-seat provided with the invention. Fig. 2 is a longitudinal vertical sectional view of the steam chest and cylinder.

In the drawings, 6 indicates the cylinder, 7 the steam-chest, and 8 an ordinary slidevalve therein. The valve-plate has the usual inlet-ports 9 and exhaust-port 10. Extending along beside each inlet-port is an oilgroove 11. These grooves are located outside the portsthat is, between the ports and the ends of the valve-seat. They are preferably somewhat longer than the ports, so as to extend beyond the ends thereof and lubricate the edges of the valve. Each of these grooves communicates by means of a passage 12 with a branch 13 of an oil-supply pipe 14, which extends through the wall of the valvechest. Oil is supplied throu h this pipe from any suitable source, prefera ly a force-feed lubricator or pump. The grooves are located under or open directly against the face or bearing-surface of the valve, and it is obvious that the oil supplied to the groove will be taken up during the movement of the valve and applied to the bearingsurfaces and across the entire Width of the valve. Furthermore, when the valve makes a stroke it will scrape or draw the oil over the edge of the port 7 and into the same, so that the steam flowing in said port carries with it the oil into the cylinder, thereby lubricating the cylinder, and no oil is carried to the exhaustport until after it shall have been used in the cylinder. In those types of balanced valves in which the exhaust finds its way to the top of the valve, such oil as may be carried out by the exhaust will serve to lubricate the top bearings of such valve.

. The invention is not confined to the exact embodiment shown, since a simple valve is used for the purpose of illustration, but is adapted for use with any type of reciprocating valve by the production of oil-grooves in w the valve-seat adjacent to the inlet-ports.

What I claim as new, and desire to secure by Letters Patent, is

In a lubricator for engine slide-valves, a

valve-seat having oil-outlets in its face adj acent to and on the outer side of or beyond the inlet-ports therein and so arranged that both will be covered by the valve during the middle part of its stroke, and alternately covered and uncovered by the valve at the ends of its strokes, whereby oil delivered from the outlets will be carried into and through the ports into the cylinder as the inlet-ports are opened respectively, and means independent of the pressure in the valve-chest, to supply oil to said outlets.

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

DAVID MOREHOUSE.
