Be itknown' that I SAMUEL A. J12, a citizen of the United States, at

.v useful Improvements in Valvesyand'I do hereby declare that the following is a. full, clear, and exact description of the inventi on, which will 'enabl'otliers skilled in theartto whichit'apperta-ins to make and use This invention relates to an improvement in valves and 'pertain's-to an improvement adaptable to many forms'ofvalves such, for instance, as check valves, angle. valves, globe valves and others.

h e invention also pertains-to improveseating faces thereof that in form outside theva-lve-body sothat the grinding agent is kept outside the; Valvebody and not permittedto pass into and through the pipe system, the construction of' the valve being such that during the grinding their surfaces will be maintained in exactly the same relative position as when in 'place inthe valve-thus insuring that when replaced said surfaces will seat perfectly tight. Other objects will appear in the following specification.

t is wellknown that'when a valve-seat or the valve restingth'ereon become damaged in anyway so asto permit the. fluid passing therethrough to leak between the ground faces it is necessary to regrind the surfaces in order that they may be made to seat perfectly andprevent such leakage. It is also well known that in some ofthev older forms of valves the grinding andrethe emery, which cannot always be entirelyrcrnoved, is carried along into'such' appa-. ratus by the fluid. It-is well known, also, that after a valve-seat has "ground a number of times it-is finally rendered unfit 5ft)? further use: forobvious reasons 'it'necessary'to remove the valve-body. from. th

making P p s,

'10 Din such a manner as to prevent leakage fectly and are not cut is inserted a tubular member or collar F of some length which constitutes the valve-seat both of whose ends the upper and lower, are 'trued and properly ground to receive the valve to be described presently. The said collar or seat has a circumferential flange G (Fig. 5) both of whose upper and lower faces are turned off true and either of which is adapted to rest upon the wall or partition way a fluid tight joint will be maintained. However, if through any cause the surfaces are defaced so as to permit leakage between them, the plug U can be removed which will liberate the valve disk, the stem 1?, and the hood HH all of which can be lifted from the valve-body .after which the valve seat F can be removed. The surfaces of these two members w 'ch have been in contact can them be ground to fit and then replaced in the valve after having cleaned them thoroughly of the emery or other grinding agent employed, or, in place of grinding the surface the member whose surface has been damaged can be inverted and then by replacing the parts the valve is ready for use. It will be seen that by having both surfaces of the valve disk and both ends of the valve-seat provided with ground surfaces four changes may be made before it becomes necessary to do any grinding or reseating in case the attendant has other more pressing duties to attend to the grinding and reseating being done when the pipe system is idle. After many regrindings and the valve-disk and seat have become too much worn to be further used they may be replaced by new ones at a very nominal cost thereby malnng it unnecessary to-replace the valve-body by an entirely new one.

My form of valve is readily applicable to any kind of valve for any purpose and besides the advantages enumerated there is the further advantage that no internal projections are present in the valve such as would retard the free passage of fluid therethrough and the thereof may be utilized in angle valves, or valves of' any particular or peculiar shape and the invention contemplates any structure that will provide a valve having the between the collar and the said wall or part1- tion. Seated upon the flange G is a hood H (Fig. comprising a dome shaped upper portion; itslower portion consisting of a ring H which bears upon said flange G. The ring H and the dome are connected by legs J which. are spaced apart to provide the openings K for the passage of fluid.

The valve hereinbefore-referred to comprises a disk L, Fig. 3, provided with an upper and lower flat face both properly ground torest upon the surfaced top of the collar F, or seat, whereby the two form a fluid tight joint. At each side of the disk L is an extension M each having a here at N whose axes are perpendicular to the plane of the disk and said bores are provided to receive two vertical stems to act as guides, the lower one-being indicated by G and the upper one by P. Cast in the bottom of the valve-body is a boss Q, vertically bored at R forming a socket to receive said stem or'guide O. The dome H of the hood hereinbefore mentioned is centrally bored at S and the guide or stem P referred to extends therethrough and has a head T to rest upon said dome. A plug U is provided for the top of the valve-body and has a threaded shank V to engage the threads of the extension C. Extending cen- 40 trally through said plug is a set screw W having a rounded end adapted to seatin a depression 2 in thehead T of the guide or stem P. Said plug U is further provided with a threaded stem U at its top to receive an internally threaded cap 3 to cover and protect the screw and prevent chance leakage. It will now be seen that the collar or seat F is firmlyv and rigidly held in osition on the partition D by means 0 the hood HH' and remains permanently in position during the time the valve is assembled and in use and the means which holds said seat in position through the hood is the set screw W described bearing upon the head T of the stem P.- w

The direction of flow of the fluid is indicated by the arrows. It passes through the seat F and lifts the disk L against the force of gravity, said disk being guided in its ver-' tical movements by the studs OP and having passed beneath the disk the fluid finds its outlet between t e legs J of the hood 1111'. .So long as the under face of the valve disk L and the upper face of the seat E fit peror damaged inany ing the valve and valve-seat when removed from the valve-body, the hood Hserves as an excellent means of holding the members in their relative positions or the positions they occupy while in service so that their surfaces will always be ground accurately. The said hood serves. to centralize the members during the grinding operation.

I amaware that the art shows a removable valve-seat held in place against the underber held against it by a plug or closure in the bottom of the valve opposite the opening of-said diaphragm. Such an arrangement, however, involves abomplicatiori of structures and is expensive besides having many parts to care for and keep tight for preventing leakage. My device, however, does not depend upon and does not utilize 'a second closure since a single closure at the top of the valve, through which, in one of its forms, the valve stem extends, is also associated with the. means for holding the structure or equivalent several advantages outlined; While grindside of the diaphragm of a valve by a memy the extension of the top of the body,
