UNITED 'STATES PATENT .()EEIcEo JOHN N. MATLOOK, OF BROOKLYN, ASSIGNOR TO BAKER, SMITH t OO., OF
NEW YORK, N. Y.
IMPROVEMENT IN GLOBE-VALVES.
Specii cation forming part of Letters Patent No. 158,296, dated December 29, 1874; application filed December 2, 1874.
To all 'whom it may concern Be it known that I, JOHN N. MATLocK, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Globe-Valves, of which the following is a speciiication:
Globe-valves are usually employed in connection with steam and hot-water apparatus, and under circumstances Where rubber or other elastic packing is difficult of application, because it is more or less softened or injured by the heat; hence, great difficulty arises in keeping the valve tight, and when the metallic surfaces are brought into contact it has heretofore been necessary to grind the valve to its seat. My present invention is made for dispensing with elastic packing, and for avoiding the grinding ot' the Valve to its seat. I make use of a valve with annular grooves in its face, and the ribs between these grooves are of a size adapted to be pressed upon the flat or nearly flat seat, and to conform to the same by the pressure only, Without grinding; and this is the result at any time, because the intervening ribs yield slightly to the pressure, and accommodate any inequalities resulting from expansion of the metal under heat. In case of any foreign substance resting upon the seat, the ribs will either cut the same or press it out of the Way.
In the drawing, Figure 1 is a vertical section of the globe-valve, and Fig. 2 is an inverted plan of the valve.
The couplings a b, body c, cap cl, packinggland c, screwfstem f, and hand-Wheel g are ot' usual construction. The valve-seat h is ilat, or nearly so, and the valve t is loose at the end of the valve-stem, so that the stein can turn after the valve touches the seat. The
surface of the valve is made With annular ribs.
and grooves, as shown, the ribs being sui-- ciently narrow to yield to any inequalities in the seat or surface of the rib; thereby the valve and seat Wear true, the one against the other, in consequence ot' the pressure, so that grinding is rendered unnecessary.
I claim as my invention- The valve t', made with a flat or nearly flat face, containing annular ribs and grooves, in combination with the screw-stem f, flat seat h, and body c, as set forth.
Signed by me this 28th day of November, A. D. 1874.
Witnesses: JOHN N. MATLOOK.
