I Specification of Letters Patent.

Patented Feb. 19, 1914.

Application filed September 1912. Serial No. 721,497.

'provement in Valves, of which the following is a specification.

The object of my invention is to provide a valve for fluids, air andgases, more simply and cheaply made, with freer passage ways, and a better seat, than valves of alike kind npw in use; the particular features of which are pointed out in the following specification, and illustrated in the accompanying drawings in which Figure 1, is a plan of the valve complete. Fig. 2, is an elevation, part being in section. Fig. 3, is a plan of the top member. Fig. 4, is an elevation of the part shown in Fig. 3. Fig. 5, is a plan of the seat broken oif at the center line. Fig. 6, is a sectional clevation of'the seat.

In the drawing 7 indicates the cylindrical base of the valve, externally, threaded for attachment to the structure for which it is required. Above this threaded part is a projecting-flange 8'wh1ch extends inwardly to a reduced part 9 of the base which is also Above this threaded of the removable valve seat, which is in;

-wardly supported by the vertical elevation 11. Supported on the table 10, and by the elevation 11, is a seat 12, which is secured thereon by the top member 13;, This top member isinternally threaded at 14V whereby it is screwed onto the part 9, of th base 7, as shown in Fig. 2. The bottom of this top member adapted to form a light joint with the'flange 8 and the internal face 15 above th'e threaded portion ll. forms an inwardly inclined angle which is adapted to correspond with the angle 16, of the seat 12,

whereby the seat is securely locked in. position in the valve. Three r1bs-17extend verj tically andthen inwardly froi'n'tbe part 14 and are connected by

rings

18, and 19, all

of which constitute one integral part. The ring-19. is cylindrical. It extends above and below the junction of the ribs, and forms a cylinderQO. The'external portion of the top is six s ded whereby the member is screwed on tothe base by means of a wrench. *blidablysupported nrtbc cylinder 2( is a'stem 21 of the puppet valve 2:2;v which is adapted to rest on the seat 12, under the pressure of a coiled spring 23, which is adapted to encircle the lower portion of the cylinder 20. \Vithin the base 7 are two lugs 24 shown in Fig. 1 which-are adapted to he engaged by a suitable tool for screwing the base into the structure desired.

'Ilhe seat 12 is preferably of elastic materia VVhilo the base is shown as an attachable member it is obvious that it may form an in:

tegral part of a structure such as a boiler,

i What I'claim is:-

1. A valve of the kind described consisting of a base, said base having an externally threaded portion adapted to support a top member, a table above said threaded portion and a vertical wall, said'table and wall being adapted for the support of a remov- .able seat; a-'seat having a base adapted to rest on said table, an internal periphery adapted to be supported by said wall and an external periphery inclined from said base upward and inward and thereby adapt.- ed to be engaged and held on said table and against said wall by a top member; a top member composed of a plurality of rings joined by a plurality of ribs, one of said rings being internally threaded and having an inwardly inclined periphery above said threaded part, whereby said member is adapted to be screwed on to the threaded portion of said base and to engage the inclined periphery of said seat and thereby lock said seat on said base, the upper ring of said top member being extended vertically and forming a vertical central cylinder; a

puppet valve having a flange-adapted to rest on said seat and a stem slidably'supported in said cylinder; and a coiled spring encircling said cylinder and stem and compressed between the flange of said puppet valve and top ring of said top member as described.

' 2, In a device of the kind described the combination with a main member having an externally threaded portion for the support of atop member, a table extending inward 'from saidthrcaded part, and awall forming the inward limit of said table, said wall being adapted to support a scat-of aseat in the form of a ring adapted to be reinovably placed on said table and supported by. iiid' wall: a. top member having an intcrnally threaded and an inclined face above said her and on to the seatsaid top member haw ing a cylindrieal the stem of a puppet valve and a coiled spring; a puppet valve having a stem sup ported in said cylindrical center of said top, and a head adapted to cover and rest on said seat, and a coiled spring sompressed center ada'pied t0 support Within said top member on said valve 2;;
