CHARLES E. WALLACE, or ToivirKINsviLLE, AND MARTIN ETIERNAN, or JAMAICA,
' NEW Yoan.
I vALvE.
To all whom t may concern:
Be it knownthat we, CHARLES F. WAL- 4LACE and MAnTiN-F. TIERNAN, citizens of the United States, residing atTompkinsville, borough of Richmond, county of Richmond, and State of New York, and Jamaica, county 4of Queens, and State of New York, respectively, have invented certain new and useful Improvements in Valves, of which the 'fol lowing is a full, clear, and exact description. The invention subject .of .fthls application for Letters Patent is lan .improvement in valves, morevespecially of that class or kind which are used for controlling the flowlof vgases 'or luidsunder 4high pressure, for
A .which purpose, as `,is wellV known, a very minute movement of the valve stem and the sure maintenanceof the valve in the position to which it has been thus broughtare essential, andjit is ldistinguishedby the lpresence of a valve stem movable from or toward its i `seatby' means of a threaded member with which the 'said stein engages, 'which member is in turn in threaded engagement with the body of the. valve and constitutes a protectiye coveringethe twothrea'ds by which the said member engagesthe valve stem and the outside of the -valve body respectively being both in ltl'iesaine direction but of diEerent pitch, the thread by which said member envgages'thevalve body'being of greater pitch than jthe thread by-which it engages the value. It .constitutes a very perfect and du.4
rable means of controhwith no parts Subj ect to appreciable deterioration from wear', its
construction is lextremely simple and the number of parts comprising itis an irreducible minimum.
The. inventi n is illustrated in the accomy panyin'g drawing in Awhich- Figure l is a vertical central section of the .complete device, and
Fig. 2 is a top plan view of the same. 'A
i The. numeral 2 designates the valve body designed or adapted to be joined to a 'pipe' or conduit carrying a gasl or fluid under.'l 3 is the valve sea and a is a pressure. Y branch outlet integral with or in any proper manner secured to the body.
The valve stem 5 is properly fashioned to' Specification of Letters Patent.
Application filed May 4, 191.8. Serial No. 232,633.

fit the seat and extends upward through a collar 6, a packing 7. and a packing land into the internally threaded cap 8 wit which. it engages.
The valve body is externally threaded'for y vthe cap and internally threaded for the packing gland which after the stem has beeniinserted is screwed down to form la perfectly tight fitting joint therewith. I f
vWhen these'parts havel been put in place theL 'cap 8 is screwed down on the end'of lthe valve body 2 and the projecting end of the stem until the parts assume the relations sho-wn in Fig. 1 with the valve stem forced ltightly down on its seat. The cap 8 has wings 9 by which it may be turned and when it ifs'unscrewed it will raise thestem up from its seat, or when turned in the opposite direction'it will .force the stem down upon its seat by reason vof the fact that the rthreads between the cap and the valve body'are of greater pitch than those between the cap and the valve stem. In either case the stem is prevented by friction with .the gland and packing from rotating, `and merely moves axially through the packing.
The fictional resistance to ing is allthat is required in practice to prevent its rotation, and n'o other means need be employedfor the purpose unless so desired. The invention, moreover, is notlimited to the specific arrangement 'of threads, as iit, is onlyvnecessary that there should be a differential' threaded engagement of the character described between the stem and the cap and between the latter and the valve body or other stationary part to secure the results rherein set forth.
What we claiml is:
1. A' valve comprising anexternally threaded valve body; a valve seat therein; anstem; axially VInova-ble to and from the seat and4 having an external thread 'in the same direction as, but of less pitch than, that on the exterior ofthe valve body; and an internally threaded cap, engaging the exten' nally threaded'valve body and constituting a protective cap therefor, and containing an internally threaded socket to receive and en- 'gage the externallythreaded stem.
,2; A -valve comprising a seat and an axi- V allv movable stem, a packing through which the stem passes, alcap with which it has threaded engagement, and a valve body with i tween the eap and the valve stein, wherebv by t-iiining` the rap the stein will be raised or lowered with reference to its seat. biitprerented b v friction 'troni being rotated.
A. valve e iiipi'i. iii; aeat, a packing* and an axialliY niovable Stein passing through the paekine'. a cap with an internally threat-hal part foi'- engaging with the t'ree end ot' the stein and with another in-l ternall)Y sere\\'-threaded part to serew onto the valve body` the threadbl between the Ca and the valve body heine' ot'greater .pitch than those between the cap and the valve, Stein, whereh)Y the tiirninag` ot' the eapwill raise or lower the stein with reference to its `@eatA without rot-ating it.
J. A Valve, eoinprisinga body, a Feat and.
body. the threads between the lap and the,-
ralve body being` of greater piteh than ythose between the eap and the valve stein.
In testimony whereof we hereunto 'attix onr signatures. I
