specificationof Letters Patent. lutenfml Oct, 19 1909, Application filed July 30, 1907. Serial No. 386,199. To all whom it may concern: A Be it known that IjFRANKLIX M. PATTER- soN,`of thecity and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Valves, of which the following is a specification.

My invention has reference to valves and consists otcertain improvenienteI which are fully set forth in the following specification and shown in the accompanying. drawings which form a part thereof The object of my invention is to provide meltjal, will wear uniformly under the action of the ialve N and may be leveled when des ired. by a file or otherwise when iL becomes worn. The inlet and eduction ports are preferably7 located to one side of.t.he center ot the casing, so that the valve-seat .E may extend laterally to one sideof the eduction port as indicated in Fig. l to permit the "alve N to bemoved laterally away from the port in opening it and yet at all -times The valve-seat E, heilig of cast a simple and. eiiicient construction of valve to support the said valve N in a proper which shall maintain itself in perfect operamanner.

tive condition by the normal operationof The aperture lV in the part D, through the valve Ain its commercial application. which .a .spindle H extends vand which it The preferred form of my invention consists of a casing having a through passageway With which the induction and eduction lpipes are connected and provided with a valve-seat and lateral extension thereof, co1nbined with a valve adapted to a sliding cooperation with the seat, a pivoted arm for moving the valve, a spindle for operating the arm extending through ther casing and forming therewith a watertight joint, a set screw for holding the spindle in place, means for guiding the pivoted arm, and a spring between the pivoted arm and valve whereby the valve is adapted to take up the wear automatically. I

My invention also snugly fits, 1s to one side of 'the valve-seat, the said .spindle being adapted, through means to be described, to slide the valve over the 'valve-seat. The outer end of the spindle H. is formed with .a polygonal head J adapted to receive the socket portionof a. hand wrench or lever K, and by which the spindle may be rocked in opening or closing the valve. The inner part of the spindle is provided with a conical flange H andabove the ilal'xge with the polygonal portion L. T he conical flange ll rests in contact W-ith an inuerpearing R on the plateB surrounding the sl'indle and with which it makes a liquid-ti, ht ground joint. A set screw l. extends through the hodyof the part C of the fusing and presses upon the end of the spindle l-l to hold its conical flangev H comprehends other feathose above s ecied, will be better understood by re erence to the drawings, inl tightly upon its seat ll. .A lock-nut l may .Which:- y lock the sct screw when adjusted.

of a portion of the valve-casing.

Figure l is an elevation of my improved valve with one-half of "the casing removed, showing the interior construction; Fig. 2 is across section of the valve on line 2-2 of Fig. 1; and Fig. 3 is an inverted plan view Fitting over the polygonal end L ofthe spindle lvl, is an arm M adapted to be moved over thc-valve-seat E.. The free end ofthis arm )fl is .provided with a large aperture -which may be hroughtii'lto alinel'nent with the induction and eduction ports, as shown in Fig. 2. The valve has a l'lat surface which rests upon lthe valve-seat E, and has an upwardly directed cylindrical hub n which loosely fits the `apertlure in the free end of the arm M. coil spring O is intel'- poscd between the arm M land the valve l\` and shielded with'ln an annular recess m B and C are two parts constituting the casing A, and these are secured together by means of screws -'l or in any other suitable manner. The general voutline of the valve, especially in the large sizes, is ypreferably kidney-shaped. The part B consists essentially of a. plate having the transverse eduction port F opening through a Valve-seat 'in the arm, vso that at all timcsthere is a. E slightly raised above the inner surface of downward pressure from the arm M. upon the plate.i The eductllon the 'valve-h to cause 1t to suuglylit to its catcs with ay tubular boss seat.

erably screw-tln'eaded for the reception'of rIhe bonnet or part C of the casing forms an inclosing cap over the valve mechanism, and is Aalso'provided with the induction port I*V and screw-threaded aperture D for thepipe, by Whichthe medium to be controlled is permitted to pass to the valve. This vinduction port F is preferably tapered to a slight extent to cause the Water and matter in suspension to converge in passing through the eduction port F, and in this Way avoid undue Wear upon the valve-seat adjacent to the eduction port. The induction portF is v surrounded by a bearing c with a lateral extension c against which the arin M travels and by which it is guided.

With the parts in the position shown` in .the drawings, the water or other mediumv entering the linduction port Il", under pressure, acts upon the exposed surface of the valve N and forces it firmly to its seat E and at the same time operates upon the inner exposed surface of the partsI L and H of the spindle H to force its conical liange H tightly down upon the bearing surface R. When the wrench or handle portion I( is rocked, the spindle His also rocked, and this swings the arm M which carries the valve N With it. By causing the valve to travel laterally to thesolid part of the valve-seat E, the valve-port If is opened an'd presents a through passageway with all the advantages lof a gate valve. When the valve opens the 1 ediiction port, the pressure upon it becomes greatly reduced, and excessive friction upon the valve-seat E becomes eliminated. The arm M is at all times spring-pressed `against I the bearings e and c, whereby it not only operates as a means to shift the valve N and spring O, but also as a means constituting when moved lateral] an abutment against which the spring O resses to hold the valve N down to its seat.` en the Inediuin being controlled is under `pressure, the spring O is not necessary to insure the liquid tight joint between the Valve and its seat, but when there is no pressure or no material pressure within the bonnet the spring then performs its function of malring a water tight joint lo prevent leakage. This would be particularly evident when einployin my improved valve as a blow-ofi' valve or a steam boiler, in. which there would be no material pressure on the valve when there was no steam pressure.

It will be seen from this construction of valve that there is'vnostul'ling-box necessary for the spindle II; and there are no set screws required .for 'adjustingthe arm M, and 'consequently no excessive ressure will come upon the Valve N should t e seat E become worn on a slight incline, due to the fact that there is more pressure 'upon the valve when over the eduction port at the time of opening than there is upon the valve with respectto said eduction port. The iquid tight 'joints are maintained Without excessive wear upon the parts constituting the joints, and no special care is required on the part of the engineer in the practical employment or adjustment of the valve in use.

The valve-seat E is preferably of no greater width than the diameter of the valve N, so that every portion of it is traversed by the said valve N in opening and closing the valve. In this manner, the wear on the ,valve and on the valve-seat will become uniform, and consequentlyA the valve as a Whole will remain in operative condition for a long period. When it is' desired to level the valveseat E or valve N should they become Worn, it is only necessary to separate the parts B and C of the casing A and to remove the valve N and smooth it with a file or upon 'any other flat surface, and also to smooth the fiat surface constituting the valve-seat E With a smooth-cut flat file. It is therefore evident that the valve maybe repaired when necessary without removing it from the place of use, and obviating the necessity of all expensive machine work, or delays in repairing incident to shipping of the valve toaind from a repair sliep.

lVhile I prefer the construction shown asv being excellently ada ted for the pur oses of my invention, the etails may be mo ified Without departing from the spirit of the invention,
