IMPROVEMENT IN BLOW-OFF VALVES FOR STEAM-RADIATORS.
Specification forning part of Letters Patent No. 22l,5 15. dated November 11, 1879; application filed October 6, 1879.
To all whom it may conccrn:
Be it known that I, WILLIAM BURLINGAME, of EXeter, county of Rockingham, State of New Hampshire, have invented certain Improvements in Blow-Off Valves for steam-Radiators, ot' which the following is a specification. t
This invention relates to means for permitting escape ofair from low-pressnre steamheating radiators; and it consists in the einploynent, in combination with the blow-off opening of such radiators, of a valve located upon the outside of the radiator, and olosing nnaided= by the pressnre of the atmosphere, such Valve being ground to its seat and provided with a regulating-screw, which serves not only to deternine the extent of its opening, but to enable the regrinding of the valve and seat to be effected, should occasion requre.
The drawing accompanying this specification represents a sectional 'elevation of a device embodying my improvement.
In the above-named drawing, A represents a tube, the inner end of which is to be screwed into the blow-oli' opening of a steam-heating radiator, the length of such tube being governed by circumstances or the locality in which it is placed, and its outer or upper end converted into a ground valve-seat, b, against or over which is placed a flat valve, c, the sten of such valve enter-ing the bore of the tube to prevent its accidental escape.
B in the drawing represents aplate or head disposed outside of the valve c, and supported upon the end of the tube A in such manner that a small space shall intervene between such head and the valve, while C represents a screw screwed through the head, and capable ot' being screwed down upon the Valve to'confine the latter closely to its seat when occasion `requires; but under ordinary circumstances the screw is removed from the valve.
under snflicient pressure to overcomethe pressure of the atnosphere, it. opens the valve and pernits of escape of air from the interior of said radiator; and when the air is expelled and the condensation of the steam within the radiator begins, the atnospheric pressure closes the valve, and the latter remains closed until the steam has been shut off, the radiator cooled down, and* steam again admitted.
Should the Valve and seat become lealy by corrosion or otherwise, asmall amount of emery or other abrasive substance is put between them, and the screw screwed down upon the valve. By turning the valve about upon its seat the adjacent faces of the two may be reground with little time, trouble, and. expense.
I claim- The combination, with the blow-ofi' opening of a steam-radiator, of the valve o, closinginward against its seat by atmospheric pressure, and the central adjusting-screw, C, by which not only the degree of opening is determined, but the regrinding of the Valve and its seat is permitted, substantially as and for the purposes set forth.
WILLIAM BURLINGAME.
