T.. DAVIS. Globe Valve.
Pa tented Dec. 11, 1877 IN- PHERS, PNOTO-UTHOGAPHEQI WASHINGTON, D C.
UNITED STATES PATENT OFFICE. I
THOMAS DAVIS, OF ST. PAUL, MINNESOTA.
IMPROVEMENT IN GLOBE-VALVES.
Specification forming part of Letters Patent No. 197,967, dated December 11, 1877; application filed October 30, 1877.
To all whom it may concern:
Be it known that I, THOMAS DAVIS, of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Globe-Valves, which invention is fully set forth in the following specification and accompanying drawings, in
which- Figure I is a sectional elevation of a globevalve, showing my improvement arranged therein; Figsll and III, smaller views, showing' the manner in which the invention may be applied to a check-valve, &c.
" This invention relates to that class of valves known as globe-valves and consists in forming them with a double seat and a doublesided valve, so that when one side is worn out I the other can be used.
The invention also-consists in forming the casing with two openings, one for the reception of the stuffing-box carrying the valvestem, and the other for a temporary screwplug, the stuffing-box and plug being made interchangeable, so that the valve may be reversed, to enable either seat to be used.
I f" A is the casing, and a a the walls, dividing ing, corresponding to the opening D in which the stuffing-box is screwed. This second opento an ordinary check-valve.
ing will be temporarily filled with a plug, E,
all the features of two separate valves, and
at but little more expense than the cost of one. 7
Fig. II represents the double seat applied This consists simply in forming the valve B with two seats, d d, and two stems, O G, which work in guides e e in the two plugs E E.
Fig. III represents the device as applied to a combined check and stop valve.
I claim-- 1. The valve-casing A, provided with the two openings D D, in combination with the double-seated valve-port c c, arranged and operating substantially as hereinbefore described.
2. The valve B, having the two seats d d, in combination with the casing A and division-walls a a, provided with the double-seated valve'port c 0, arranged and operating substantially as hereinbefore specified.
. In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
THOMAS DAVIS.
