WILLIAM MQGORD JAMIESON, OF UNEHUNGA, AUCKLAND, NEW ZEALAND.
STEAM-VALVE AND FITTING THEREFOR.
To all whom it may concern Be it known that I, lViLLIAM McCoRD JAB/IIESON, a subject of His Majesty the King of the United Kingdom of Great Britain and Ireland, resident of Onehunga, in the Provincial District of Auckland and Dominion of New Zealand, have invented I1nprovements in Steam-Valves and Fittings 'ldherei'or, oil? which the following is a specification.
This invention provides for an improved term of steam valve, constructed so that the valve and valve seat are not subject to the action of? the steam in passing through the valve when in use, as is the case with the usual forms of valves, thereby necessitating frequent adjustment of the valve and valve seat.
The valve casing is constructed with the usual inlet and outlet passages extending out through opposite ends thereof, the inner ends of the inlet and outlet passages being connected by a vertical passage. Surrounding; the passage is a circular groove in which sits the hollow valve. Steam ports are formed in the hollow portion and the flanged portion of the valve is of larger diameter than the hollow portion, so as to sit on the valve seat which is formed around the outside oi? the circular groove.
Referring to the drawings which accompany this specification, Figure 1 is a sectional view of a complete steam cock fitted with a valve and valve seating constructed according to this invention, the valve being shown in its closed position, Fig. 2 is an en larged detail view of the valve and valve seating, and showing the valve in its open position, and Fig. 3 is a side view of the valve alone, showing steam ports formed therein.
The valve casing is formed with the usual inlet and outlet passages A, the inner ends A of which are connected by a vertical passage l3 forn'ied through the enlarged portion l of the partition D. Surrounding the vertical connecting passage B is a circular groove or recess E, which extends downward nearly the full length of the passage B, and in which fits the hollow valve F.
The flanged portion H of the valve is of Specification of Letters Patent.
Application filed July 31, 1912.

larger diameter than the hollow portion or annulus F, and has its underneath surface H upwardly and inwardly beveled to enable the edge of the bevel to sit on the valve seat 1 formed around the edge oil. the circular groove or recess E, when the valve is fully screwed down.
Ports J are provided in the hollow portion F, which when it is desired to turn on the steam, are brought sul'l'iciently up out oi the circular recess l0, by the screwed spindle M to enable them to clear the top B ot' the passage B. This permits the steam to pass through the ports J, from the inlet to the outlet, without expending any of its tor-cc on or forcing grit or the like againstthe valve seat I or flanged portion lil. oil the valve.
The special. advantage in constructing the valve as described, is that the steam and accompanying grit and the like, is directed out through the ports J, so as to be clear oi. and not touch the flanged portion ll of the *alve, or the valve seat it. This (mnsiderahly lengthens the life of the valve and valve seating, doing away with the ncce 'sity of frequent adjustment, while at the same time the steam can be regulated to any pressure.

Having now fully described my invention, what i desire to claim and secure by Letters Patent is A steam valve of the kind described, comprising a casino; iliorined with an inlet and outlet; a depending member 'l orming an in tegral part of the casing and constituting a passageway between the inlet and outlet and having deep, vertical, annular groove; a seating; formed with a downwardly inclined. beveled portion; a vertically adjustable valve formed with :1 depending annulus adapted always to engage in said groove said annulus formed with a pllu'ality oi? ports, said *alve also having a. flanged portion beveled on its under side which is of larger diameter than said annulus and adapted to coact with the beveled portion oil said seating.
