UNITED VSTATES JAMES IOW'ELL, OF
CINCINNATI, OHIO.`
IMPROVEMENT I'N GLOBE-SOCKS.
Specification forming part of Le* ters Patent No. 47,565, dated May 2, 1865.
.To all whom ama/y concern:
Be it known that I, JAMES POWELL, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Globe-Cocks; and Ido hereby declare the following to be a full, clear, and exact description thereof', reference being had to the ac companying drawing, making part ot' this specification.
My invention relates to the class of' cocks commonly known as globe-valves," in which a screw cut upon the valve-stem is employed to close or press the valve down upon its seat or to elevate it therefrom; and it consists in a mode of constructing such cocks which enables the accurate and expeditious grinding ot the valve to its seat, and also of regrinding the same when worn irregularly by use, and this without adding to the number or expense of parts composing the cock, and without the necessity of detaching the cock from the parts with which it is connected in use.
In the common globe valve or cock the valve is guided to its seat wholl y by the thread on the interior ot' the screwcha1nber, which lhread is not and cannot be used to guide the valve in the act of grinding, a temporary plug being employed for that purpose. This mode ot' construction demands, ot course, an exact agreement ot centers between the screwchamber and the plug when they are respectively .in position in the cock, and such agreement being very difficult to attain, leakage is a frequent result. The customary construction also requires for each valve to be carefully fitted to its proper body, to which alone it is applicable, whereas cocks made on my plan may be composed ot pieces taken at random, without selection or any tedious adaptation of the screw and seat to bring them into line.
The accompanying drawing is an axial secl' tion of a cock embodying my invention.
The body A ot' the cock has a neck, B, having a smooth cylindrical interior, I), and a screw-threaded exterior, b', which exterior receives the interiorly'screw-threaded screwchamber C o, which chamber is surmounted by a customary stuftingbox, D. The valvestem E is provided with three or more wings, F, which it and slide snugly within the cylindrical interior of the neck, while yet otlur wings, F', beneath the valve G, occupy tl e cylindrical passageway H of the valve-seat.
1t will be seen that said wings and their inclosing cylinders discharge the entire duty of guiding the valve-stem and holding the same in a true line with theseat, irrespective of the screw-chamber, which is consequently not required to be so accurately in line as in the common globe-valve. The screw-chamber C has on its under side a cavity, c', to receive the wings F when the stemis fully retracted.
When it is desired to grind the valve to its seat, the screw-chamber C is unscrewed, as in the drawing, and the valve is momentarily withdrawn to receive the sand and water or other abradant, and, being returned to its place, the grinding is effected by grasping the handle I and vibrating the same witha downward pressure.
It will be seen that the wings F and F', which aet to guide the valve in actual use,
are the very same which hold it to a truly axial position and prevent any wabbling or lateral displacement in the act of grinding, as above.
It will also be seen that the valve may at any moment during theoperation of grinding or regrinding be momentarily withdrawn for the introduction of the grinding material or abradant.
It is also apparent that bymy mode of construction the bodies and valves may be made separately in large numbers and quickly fitted together Without the delay of selection.
I have selected to illustrate my invention a form which I have found efficient in actual the precise arrangement here represented, so long as I attain the saine result by means substantially equivalen t--for example, instead *of the upper wingsTF, th'evalve-stem may be provided with a collar ttting the cylindrical interior b of the neck B, while the lower wings, F', may be replaced by a 'slender axial prolongation, occupying al socket in the body or globe. y
I am aware that it is common to construct globe-cocks so that their valve-stems i can be held in a perpendicular position during the operation of grinding, but Ifknow of no in use, but do not propose to restrict myself to` stunee in which these results have been :Ltstrnoted and guided lsubstantially as herein tained With a valve-stem and Valve adapted set forth. to be fitted and ground independentlywof Vits In testimony oi' which invention I hereunto sorewchamber, amd Without .the aid of an set my hand. auxiliary or additional piece. Witnesses JAMES PUWELL.
I claim herein as new und of my invention- GEO. H. KNIGHT, The combined valve and valve-Stem, con- JAMES H. LAYMAN.
