LUBRICATOR FOR SLIDE-=VALVES.

SPECIFICATION forming part of Letters Patent No. 463,904, dated N ovember 24,1891.

Application filed December 30, 1890. Serial No. 376,243. (No model.)

To all whom it may concern:

Be it known that I, IRA J. LEITER, of Ionia, in the county of Ionia and State of Michigan, have invented certain new and useful Improvements in Lubricators for Slide-Valves; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification.

This invention relates to certain improvements in lubricators for slide-valves'for steamengines.

The invention consists in the construction and arrangement herein set forth, and particularly pointed out in the claim.

Referring to the accompanying drawings, Figure 1 is a section taken through the steamchest and valve longitudinally of the ports, showing two different constructions. Fig. 2 is atop plane, the valve being shown in dotted lines, the top of the steam-chest being removed and two constructions being shown, as in Fig. 1.

In the drawings, the reference-letter a indicates the steam-chest having the valve-seat b, upon which the valve a reciprocates, as usual. The valve-seat surrounds the steamchest 0 d and the central exhaust-port c. This steam-chest, the valve, and ports are of very ordinary and usual construction. The portions of the valve-seat at the ends of the exhaust-port are always covered by the slidevalve. A vertical hole f is drilled in said seat from the top thereof down a suitable distance, and then if the bottom of the chest is formed as usual at the right-hand side of Figs. 1 and 2, a horizontal hole 9 is drilled through the outside of the steam-chest inwardly, so as to open into the lower end of a vertical hole f. A tube h is suitably secured in the outer end of this horizontalhole g, and is extended upwardly and carries any suitable oil cup or receptacle 6, discharging thereinto at the point upon the working face of the slide-valve. The upper end of the hole f is countersunk. Hence it will be obvious that any suitably-valved lubricant can be supplied by the conduit to the working face of the valve-seat at the point always covered by the valve, so that the steam-pressure will not affect the flow of the lubricant or blow the same out through the supply-conduits.

The construction or form of the steam chest or valve need not be varied in any way, and no peculiar construction of the same is required, as my invention can be applied to any ordinary steam chest or valve.

Where the bottom of the steam-chest is of the construction shown on the left-hand of Figs. 1 andvi, holes are drilled through the outer wall of the steam-chest and through the inner wall of the valve-seat, registering with hole f, and the tubej is then inserted, so as to discharge from the oil-cup into said hole f. In some cases the tubej is continued longitudinally through the exhaust-port and the opposite end of the same, and there opens into the hole f. This tube can discharge into holes f at both ends of the exhaust-port, or into a hole at only one end of the exhaustport. In small engines one hole f is sufficient to lubricate the slide-Valve. tubes are made steam-tight.

The many advantages of this invention are obvious and readily understood by those acquainted and experienced in this art.

My invention is radically different from, and I do not herein claim, a lubricating arrangement for slide-valves consisting of passages formed in the slide-valve itself and opening on the under face of the slide-valve and arranged to alternately register with passages in the valve-seat, through which said valve-passages receive oil, said valve-seat pas sages opening into the interior of the steamchest, so that the oil is forced into the slidevalve by steam-pressure in steam -.chest. Hence if the pressure he very great the oil is apt to be blown into the steam-chest from be neath the slide-valve.

\Vhat I'claim is- In a valve, the steam-chest and its valveseat, the slide-valve having the imperforate underbearingsurface on said valve-seat, the vertical passages f f in and opening through the upper surface of the valve-seat at oppo- All joints and site ends of the exhaust-passage and counter- In testimony that I claim the foregoing as sunk at their upperends, the pipeh, provided my own I affix my s gnature 1n presence of 10 with a source of lubricant, and a passage two witnesses.
