J. PORTEOUS Cylinder LCG ok 1 15 4 8 5 Mmm: JUN 271371 Fig.l.
INVENT @a ATTEST.
M' M s/f/ JOHN PORTEOUS, OF CINCINNATI,`OHIO.`
IMPROVEMENT IN cvLlNDER-cocKs.'
Specification forming part of Letters Patent No. 116,485, dated June 27, 1871.
To all whom it may concern.'
Be it known that I, J oHN PoRTEoUs, or"Y Gincinnati, Hamilton county, Ohio, have invented certain Improvements in Automatic Discharge- Cocks for Steam-Cylinders, of which the following is a specification:
This invention relates to that class of cocks or valves which is applied to steam-cylinders i'or the purpose of discharging the water of condensation from the saine; and my improvement consists in constructing said cocks in such a manner that they will automatically open and relieve the cylinder of Water as soon as any accumulates, and yet will remain closed against the 'pressure of steam.
The drawing is an axial section of a cylindercocl, embodying my improvements.
A represents that portion ofthe device which is screwed into the steam-cylinder. B is the barrel of my cock, which has the customary longitudinal bore i), whose discharging end is capable of beingI closed by a valve, C, having` a stem, c, that plays Within a chamber, d, of the adjustable screw-threaded cap, nut, or handle D. Interposed between the top o valve C and inner end of cap D is a helical spring, E, which serves to retain said valve against its seat as long` as no Water is in the cylinder; but as soon as any accumulates i therein the extra pressure of the same forces the .to suit the actual pressure ofthe steam, so as to discharge the water Without Wasting steam, and that this adjustment can be promptly made at any time without removing any part ot' the cock; nor can the cock ever be entirely closed by accident or otherwise. The stem o is confined to an axial position within the barrel B by means of Wings G, which project radially from said stem.
' l claim as new and of my inventionln the described combination with the barrel B b, automatically-acting valve C c,- spring E, and
discharge-pipe F, the screw-cap D d adjustable from the outside, as and for the object set forth. ln testimony of which invention 1 hereunto setx my hand.
