UNITED STATES PATENT OFFICE.
JOSEPH BARBE, OF SAINT-AMAND, NORD, FRANCE.
SAFETY-VA LVE.
SPECIFICATION forming part of Letters Patent lN'o. 328,451, dated October 20, 1885.
Application filed June 19, 1885. Serial No. 169,212. (No model.) Patented in England November 19, 1880, No. 4,770, and in France January 4, 1881, No. 140,417.
To all whom it may concern;
Be it known that I, J OSEPH BARBIE, a citizen of France, residing at Saint-Amand, in the Department of theNord, France, have invented new and useful Improvements in Safety-Valves for Steam-Boilers, (for which I have obtained British patent No. 4,7 7 0, dated November 19, 1S80,and French patent No. 140,477, dated Jannary 4, 1881,) of which the following is a specification.
This invention relates to a means for pre venting explosions in steam-boilers. The 0rdinary safety-valve, which relieves excess of steam when under excessive pressure and then closes when the pressure diminishes, operates well under ordinary conditions, but it does not prevent explosions, notwithstanding all the oversight that can be given.
The present invention consists in a reliefvalve constructed and arranged to empty the boiler when excessive pressure is generated therein.
The best mode known to me of applying the principle of the invention is illustrated in the accompanying drawings, in which Figure 1 is a central vertical longitudinal section of one end of a steam-boiler with the relief'valve attached; Fig. 2, a view in cross-section, and Fig. 3 a view showing the operation.
A is the steam-boiler, provided at the end farthest removed from the fire with an open ing, which is normally closed by the valve E. This valve may be of any suitable formsuch as a disk, for example-but is preferably in the form of a stopper, of copper, with a beveled flange near one end,as shown. The valveseat 0 is formed by a cylinder set in the casting d, bolted or otherwise attached to the boiler. The valve E is held to its seat by the weighted lever G, fulcrumed at Z in the forked piece L, tapped into the casting d. The link or bar F, pivoted at 0 to the short arm of lever G, is interposed between the lever and the valve. It has a pin at the outer end, which enters a depression in the bottom of the valve to prevent its accidental displacement.
The weight H is suspended from the lever by the strap h, so that it can be adjusted nearer to or farther from the fulcrum Z, in order to regulate the pressure with which the valve E is held to its seat.
WVhen excessive pressure is generated in the boiler which cannot be relieved by the ordinary safety-valve, the valve E is forced out until it is clear of the valve-seat c, and thereupon the link F turns, allowing the valve to escape from between the lever and the valveseat. The lever is then tilted by the weight H into the position shown in Fig. 3. The opening in the boiler therefore remains open, allowing the boiler to empty itself.
To prevent the radiant heat, hot gases, and smoke from the firefrom acting upon thevalve, the chamber in which it is placed is cut off by suitable walls from the fire-space F and smoke'flues, as shown in Fig. 1. A conduit, M, is preferably placed below the escapeopening, being shown bolted to the casting d, with the long arm of lever G projecting through a slot in one wall. This conduit conducts the escaping water to a waste-well, P, or to other suitable receptacle or place of delivery.
It is evident that modifications may be made in the details of construction and application. The forms, dimensions, materials, and proportions of the different parts can be varied to suit local conditions or for other objects without departing from the spirit of the invention.
I claim- 1. In combination with a steamboiler, a relief-valve placed under the same, and con structed, substantially as described, so as to remain open, and thus empty the boiler when it is actuated by excessive pressure within the boiler, as set forth.
2. The combination, with the valve and valve-seat, of the weighted lever, and the link or bar interposed between the lever and valve for holding the latter to its seat, substantially as described.
3. The combination, with the steam-boiler, havingadischarge-openinginthebottornthereof, of the valve, valve-seat, lever, and interposed link or bar, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
JOSEPH BARBE.
