To ALL WHOMIT MAY OONOERN:

Be it known thatwc, JOHN S. EVERITT and OSSLAN- COOK, of the ci'ty of Oshkosh, county of Winnebagmj and j State of Wisconsin, have invented a new and improved Balance Oscillating-Valve `for- Steam-Engines; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, referenccbeing had to the annexed drawings, making a. part of this specification, in which- YFigure 1 is a vertical cross-section, cutting through dotted line 2 2 in fig. 2.

Figure 2 isa verticalflougitudiual section, cutting through the centre of iig. 1.

Figure 3,is a longitudinal section of valve H, tig.' 1..

Figure 4 is a vertical cross-section of valve H.

A'A is the valve-case orsteam-chcst. BB arehead's of valve-case. C is the'valve-stem. D D', E, are steamports. Iljare induction and eduction-pipes. O are induction and eduction-passages. H is an oscillatingbal'ance valve, wherein m m, fig. 3, are arms, secured to the stem inan adjustable manner by set-screws. S S are the outc` shelves and valve-holes of the valve. -nrt are double-inclined planes, with slots xx, and are attached to and form the inner connections of the valve, and are adjustably connected with bolts to the arms mim, as seen in igs. 3 and 4. G is a crank, where power is appliedto oscillate the valve.

' Our invention consists in providing la. cylindrical valve-case with an voscilluting-balance valve,1vith.the arrangement and adaptation of the valve-case, steam-ports, passages, and pipes, and Vthe'arrangement and adaptation of the case and accessories thereto. i Our invention further consists in the constructing of the valve, wherein the opposite bole's are respectively i provided withinclined planes on the inside thereof, slotted to receive adjusting-bolts, and respectively attached to arms that may slide on the valve-stem, thus being adjustable relative to the inclined planes-andthe valves, and made tofcompensate 'for the wear oi' the valve andthe valve-seat. v

The valve and valve-case are constructed of metal, with the valveH covering the port VD, as seen in g. 1. The stea'rn' will bc rcceivcdfrom the pipe I, as an induction-pipe, and pass the port D in the direction indicated by the arrows, and delivered to the engine-cylinder through the induction-passage The steam will be exhausted through the passage Ol inthe direction indicated by the arrow, and through the port'E into the pipe I', as an exhaust-pipe, (seen in iig. 2.)

The induction andeduction-pipes I may be both connectedwith the boiler,'and with an exhaust-pi`pe in Y any manner known to the art, so that by making the proper adjustment the steam can be instantly changed from onepip'e to the lother, and the engine instantly rovcrscd, thus making I theinduction-pipe, and I the eduction-pipc, the valve working equally well, and thus giving either an internal or external pressure upon the valve,` as lmay be found best, and likewise affording a convenient means of reversing the motion of tne engine What'we claim as ourinvention, end desireto secure by Letters Patent, is- I 1. The 'valveboles S S of the valve H, constructed withincl'ines n n, slots ww, arranged relatively to the arms m m, and valve-stem C, as a means of adjustmentin compensating for wear.

2. The .valve-case A A, when constructed as described, and arranged relatively to the oscillating-balance valve H.- as herein set forth. A
