Description

UNTTnn STATES JOHN BROUGHTON,
OF NEW YORK, N. Y.
IMPROVEMENT IN STEAM-GAGE COCKS.
Specification forming part of Letters Patent No. 52,52 E dated February 13, 1866.
To all fuhom it may concern:
Be it known that l, JOHN BROUGHTON, of the city, county, and State of New York, have invented a new and useful Improvement in Compression Gage-Cocks; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.
The drawing, consisting of only one ligure, is a longitudinal elevation ot' the cock, partly in section, showing the arrangement entire with the valve closed. v
A is the globe or body of the cock, and B its shank, which is screwed into any boiler to which the cock is to be applied.
O is the outlet-passage, communicating with the boiler through the shank.
d is the discharge-passage through the nozzle e.
F is a cylindrical and conical pointed valve, passin g through and supported in a correspending opening made through the front portion of the body A, and is free to move in a longitudinal direction, and also to rotate on its axis. Said valve is provided at its outer end with a projecting head, whose exterior end is made convex or rounding, while its interior surface forms a shoulder in connection with the stem of the valve. Between this shoulder l and the outer end of the body A a spiral spring, J, is placed, which, when the valve is closed, as shown in the drawing, is in a compressed condition.
G is a tubular cap, provided at one end with a flange, to which is attached a wooden knob or handle, H, and at the other with an internal screw-thread, which screws onto an external one on the outer end of the body A.
The valve F being free to move in a longitudinal direction when the tubular cap Gis screwed onto the end ofthe body A, its inner surface, K, is brought in contact with the outer convex head of valve F and forces the valve forward until its opposite end enters the conical seat in the body A, and thus closes the outlet-passage communicating with the boiler. By reversing the motion of the handle H and cap Gr, as in the act of unscrewing, the valve E will be free to move in a contrary l direction, and will be opened by the pressure within the boiler acting on its inner end and by the action of the spiral spring at its outer end. When steam is up or there is pressure within the boiler the. actionv ot' said spiral spring is not required to open the valve; but it is placed on the valve as an independent means 'ot' openingl it when there is no pressure within the boiler, its action being` constant andtending to force the valve outward in a longitudinal direction, and thus to withdraw it from its conical seat, when the tubular cap G is slightly unscrewed or slacked back.
One of the objects of this invention is, first, to arrange and construct a gage-cock in suoli manner that while it is simple both in rconstruction and operation the valve may be reground to its seat when it becomes leaky without disturbing the joint connecting it with the boiler, and without the use of tools of any kind or description.I rlhis is effected by the arrangement ot` the body A, detached valve F, and tubular cap Gr. By unscrewing the cap G from the body A by hand, as in the act of opening the cock, the outer end of valve F is exposed, and is free to be withdrawn by finger and thumb from the body'A. Itis then free also to be rotated on its axis, which may be done by taking hohl of its outer end with the nger and thumb. Thus b v taking ott' the cap Gr the valve may be withdrawn and examined at any time., and may be reground and thecap replaced in a few minutes and without the use of toolsof any kind.
Another object is, second, to construct a compression gage-cock in such man-ner that while its valve is free to move in a longitudinal direction, so that it may at any time be withdrawn, and while it is also free to rotate on its axis, so that it can be reground, yet the said valve will not rotate on its seat in the act of closing. This is effected by rounding the outer Aend or head of valve F and making the part of its surface which is in contact with the inner surface of cap G approximate to a pivot. When the cap G is rotated the valve F is forced forward until it rests on its conical seat, and the surfaces in contact at that end being comparatively large and spread out to some distance from the. axis of the valve, while the surfaces in contact between the other end of the valve and the cap G are conto pack the said stem ut its outer end 21ndl ndnlit ofthe cock being operated under highpressure without the possibility of scolding the hund ot' the operator. This is effected by the 'fnrangement ot' the tubular cap Gr in connection with the valve F und body A. The outer end ot'valve F, which projects beyond 'its bearing in the body A, is the portion ot' the stem usually packed by n stufling-box in gage-cocksof the ordinary construction to bensed under high pressure; but since it is in my improvement surrounded und covered by the tubular carp G, no steun] or water can be blown outl in n forward direction, and should the screw connecting" the cap with the body become rather loose, so as to allow a slight escape of vapor, it would be discharged backward or in a direction from the hand ot' the operator toward the boiler.
l claim as new and desire to secure by Letters Patentv l. ln combination with the body and shank ot' u gage-cock provided with u suitable outlet-passage, :L detachable valve, when said `vulve is supported by and has its bearing' in snid body independent of the operating; han die or screw, substantially as set forth.
L. In u compression gage-cock provided with n detachable und independent vulve sup ported by and having its hearing in the body thereof, the tubular cap whereby to operate the valve F, substantially :Ls set forth.
3. The comiiinntion ofthe body A, detachnble valve F, und tubular cap Gr, when nrrang'ed und constructed substanti-(illyns set forth.
