Description
UNITED STATES PATENT OFFICE.
WM. UHESLEY, OF CINCINNATI, O'HIO.
'IMPROVEMENT IN GLOBE-VALVES.
lfo mit rcito/m Yit may concern.'
Be it known that I, "WILLIAM GHESLEY, or
Jincinnati, Hamilton county, Ohio, have invented a newvand useful Improvement in Globe- 'V'alifes 3 and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to thevaccompanying drawings, making part of this specification.
lily improvement relates to the class of 'cocks known as globe-valves 5 and itconsists in providing the cap of the smiling-box with an interior screw to receive the thread of the valve-stem, which thread is situated wholly on the upper portion ot' the stem and operates above the stuffing and exclusively in said cap, which thus discharges the office of a nut, in addition to its ordinary and proper functions, the interior of the huh being threadless, and
servin g equally to guide the smooth lower portion of the valve-stem both in the act of grinding and in ordinary use as a'val've.
Figure lis an axial section of my cock in condition'for use. Fig. 2 isa similar section of the same in condition for grinding. Fig. 3 is an axial section, showing a modification of my cap.
A represents the body or shell of the cock.
B is the customary oblique diaphragm, having the usualeircular opening, G, whose cham fered margin forms the seat I) for a conical Valve, E, of the ordinary form.
Immediately above the opening (l, and coaxial with the said opening, thebody A has the Y customary circular hole around which the body rises in the form of a neck, G, screw-threaded (g) interiorly to receive my extcriorly-screwthreaded hub H, whose central aperture, h, instead of taking the form and discharging the office of a nut for the valve-stem, is left entirelysmooth and cylindrical, so as merely to lguide the valve-stem, which steinis correspondingly smooth and cylindrical at vits lower portion.
I is a customary stuing-box inv the upper p art of the hub, screw-threaded (i) for the at-I '4 tachment of my cap J, which cap differs from the common form in having its crown thickenedand its central aperture screw-threaded (j) to t the screw-thread of the valve-stem.
K is a gland of the usual form.
The Valve E maybe of the accustomed conical shape, but its stem M, instead of being screw-threaded near the valve and wholly be-- low the stuffing-chamber i', is entirely smooth at that partm of its length to fit cal aperture of the hub, while the usually smooth upper portion of the stem is for a portion of its length screwthreaded (m) to fit the screw-threaded interior of my cap,y which cap is thus made to exercise the functions ot' a nut. Thus the screw-thread of my stem, instead of being wholly below the stuffing-chamber and working into the interior of the steam-chamber, is wholly above the stuffing-chamber and works out through the extreme top of the stuif-v iigbox. A portion, m", of my stem 'above the thread is cylindrical, to t the tops or points of the threads inthe central aperture of the cap J.
To prepare my valve for regrinding it is only "necessary to screw oft' my cap J, as in Figa-2,*
which liberates the thread of the stem and enables it to befreely workedvv up and down as well as rotated in the plane of the valve.
I have selected as'the preferred type of my improvement the precise form which I have adopted in practice, butlthe same may obviously -be modified without departing from the essential characteristics of my invention. For example, the gland K may be dispensed with and the stungmay come directly in `contact with the cap, as in Fig. 3.
I claim herein as new and of my invention- A globe-valve the part of whosestem below the stuffing-chamber is smooth to iit the correspondingly-smooth interior of the hub, and the portion of whoses'tem above the stuingchamber is partly screw-threaded and partly smooth, so as to coact with the interiorly-screwthreaded cap of the stuiiug-box inthe manner explained. g
In testimony of which invention I hereuntoj" set my han-d.
WILLIAM oHEsLEY.
