,App1ication fi1ed December 10, 1906. Serial N0.;84'7,075.

To all whom it may concern:

Be it known that I, WEIJAM G. Enumera- HOFF, a citizen of the United States, residing at Wilkinsburg, in the county of KHegheny and State of Pennsylvania, have invented certain new and useful Improvements in Valves, of which the following is a specification, reference being had therein to the ac- "the construction shown in the companying drawing.

My invention relates to improvements in valves, particularly hydraulic valves sub j ected to high pressure, and it has for its. ob-

ject to provide a onstruction whereby all Wear between the movin parts may be compensated forto secure uidtight engage; ment at all times. This object is secured by accompanying drawings wherein, I

Figure 1 is a partial view in side elevationof the upper portion of the valve. Fig. 2 is a vertical sectional view on an enlarged scale showing the valve in position for supplying pressure. Fig. 3 is 'a cross sectional detail new on the line III. .III. of Fig. 2.

Fig. 4 is a detail view of the movable, element o-f-the valve showing the modified construction of the seat.

In the drawings 2 represents the casing of a reciprocating valve constructed for the purpose of supplying pressure to any point of utilization 1n one position, and to exhaust therefrom in another position, in the manner well understood with this classof devices.

3 is a reciprocating valve, preferably cylindrical in form, mounted'w thin the vertical cylindricalinterior of the casing 2, and

provided with a transverse port 4 ads tedto register with the supply channels 0 the valve at each side to accomplish the object desired. The valve '3 is also provided-with an exhaust port 5, adapted in the lowered position of the valve as shown to register withthe supply passage-leading from the source of pressure to the motor, and to permit exhaust therefrom in the ralsed'position,

. as indicated in dotted lines in Fig.- 2.

Ordina r il in valves of this character there isconsidera le wear on the moving element andthe faces with which it makes contact, due to the excessive pressure of the fluid employed, grit, sand, and other impurities, and the objects of my construction-are to provide means whereby such wear is compensated. For such p atively mova 1e or floating circulation nipples 6, 6, adapted to term continuations seate in convenient ecesses or hearing? on packing construction at the u ose I provide one or more relof the main circulation pipes 7, 8, at each side of the. valve casing, which pipes are secured into suitable receiving and S11 ply por tions as the flanged caps thereof, hy' screw threads in the usual manner. By this ar rangement, the outer ends of one or both of the floating nipples are subjected to the full pressure of the fluid, and are thus constantly pressed inwardly against the face of valve 3 at one or both sides. Between said caps and 'the fioating nipples "6 I referably insert springs 9, 9,01? any suita 15' construction, but 'referably hellcal in form, suitably the inner side oftheca'sing walls and arin inwardly at each side against the outer en s of nipples 6. By this construction, as the inner ends of the nipples are worn away .or as the abutting faces of the valve become worn, the pi ples will be automatically. and constantly a' usted to make .a tight hearing The ni ples-are preferably mounted within oxes formed in the casing whereby therewith, thereby absolutely preventingany leakage."

packing 10 of leather disks or other suitable material may be adjusted around the nipples by meansof followers 11 and adj ustlng nuts 12 threaded in the interior of the case 'ing, as clearly shown. Any other suitable packing mechanism .may be employed if desired, and 'as thus constructed a completely fluid-tight arrangement is provided.

' For the purpose of lubricating the valve 3 I provide One or more oil channels 13, surrounding the up from an oil cup desired.

'The valve 3 is raised and lowered by means of a lever 15' connected by stem 16 and lower or either of the inner faceso the vertical slide-way for the valve 5, whereby said valve is embraced at all times by streams of oil, furnished from the exterior thrgugh lateral openings 14:

or in any other manner passing through cap .17 brother suitable per end of the valve casing, the lever 15 be1 ng pivotally mounted at 18in an upwardl disposed postextension 19 of one of the va ve caslng caps. By th1s; or any other suitable arrangement the valve 3 is located in its desired position for supply or exhaust resipectively. In Fig. fl: have struction of valve 3 ha the ports 4 and shown amodifiedcon- 1 5, the surrounding bearmg face of saidvalve adjacent tosuch bounded within a groove or recess 20, limitingat its top, bottom andlsides the sliding face with respect to the nipple 6, by whichcon-struction it will be seen that the sliding face of the valve with respect to said nipples is terminated by shoulders whereby the wear will be even throughout and a fin or terminal ridge avoided, thus insuring (1 good contact at all times.

It will beunderstood that various changes or' modifications may be made in the design, construction or arrangement by the skilled mechanic, but all such changes are to be considered as within the scope of the following claims.

l/Vhat I claim is:

1. In a valve, the combination of a casing, a sliclingly mounted portedvalve therein, floating circulation nipples slidingly mounted in the casing arranged to abut against the valve and to furnish circulation therethrough, outer caps secured to the casing provided with circulation connections and inlet and outlet apertures in alinement with the floathig nipples, said caps being pro- Vided n ilh spring -bearing recesses, and spiral springs inserted between the caps and the ends of the nipples arranged to press them inwardly against the ported valve and to provide an interior circulation space, substantially as set forth.

2. In a valve, the combination of a casing, a slidingly mounted ported valve, therein, floating circulation nipples slidingly mounted in the casing arranged to abut against the valve and to furnish circulation thereinserted between the caps and the ends of the nipples arranged to press them inwardly against the ported valve and to provide an interior circulation space, substantially as set forth.

3. In a' valve, the combination of a cy lindrical casing having oppositely arranged connecting portions '.With hollow interiors leading to the interior of the casing, a slidingly mounted ported valve within the casing, floating circulation nipples mounted within the connecting portions, packing devices'surrounding the nipples within said connecting portions, outer caps secured on said portions provided with fluid circulation connections and inner spring seats, and springs inserted between said seats and the ends of the circulation nipplesarranged to press .the nipples inwardly against the v ported valve, substantially as set forth.

} In testimony whereof I afliX my signature in presence of two witnesses.
