STEAM-=TRAP...
SPECIFICATION forming part of Letters Patent No. 380,281, dated. March 27, 1888. Application flled December 6,1887. Serial No. 257,142. (No model.) Patented in England November 10, 1887, No. 15,345.
To aZZ whom it may concern:
Be it known that 1, PETER FYFE, a citizen of the United Kingdom of Great Britain and Ireland, residing at Glasgow, in the county of Lanark, Scotland, have invented new and useful Improvements in Steam-Traps, (for which Letters Patent No. 15,045 were granted to me in Great Britain November 10, 1887;) and I do hereby declare that the following is a full, clear, and exactjdescriptiou of the invention, which will enable others skilled in the manufacture or art to which it relates to make and use the same.
My invention relates to improvements in steam-traps, whereby such traps are rendered intermittent in action as regards the discharge of water accumulating therein, the water being automatically blown off at the full bore of the outlet-valve, instead of as in ordinary traps, a constant drip, accompanied by the escape of steam, taking place.
As represented in longitudinal vertical section at Figure 1, in crosssection at Fig. 2, and in plan with the top part or cover removed at Fig. 3 of the annexed drawings, the improved sLeani-trap'consists of a covered casing, A, which is divided by a web, A, and disk H into three compartments, B, O, and D, to the main one, B, of which the water and steam from the pipe or vessel to be drained is admitted by an inlet, E, while the second one, 0, serves as an outlet for the water'discharged from the first, and the third compartment, D,is intermittently and automatically placed in communication with the steam-space of the first-mentioned compartment, in the manner hereinafter described, for the purpose of opera-ting the discharge-valves. Toward its lower end the web A extends intolthe compartment (3, and has fitted in it a tube, F, forming a seat for a valve, G, through which, when it is raised, the water in the compartment B is discharged, the water passing out by small orifices f in the lower end of the tube F. Between the compartments 0 and D an elastic disk or diaphragm, H, preferably of metal, is secured, and upon the admission of steam under press ure to the compartment D this disk H bears down upon a flangedpiece, g, which is screwed or otherwise adj ustabl y attached to the upper end of the valve-spindle g, and thereby closes the valve, while upon the discharge of the steam from the compartment D and the pressure upon the disk H being relieved the valve is raised by the pressure of the steam upon the surface of the water in the compartment B, and permits of the escape of the water, which, being discharged under pressure, may be led to a point at a higher level. The alternate admission and discharge of the steam to and from the compartment D to control the operation of the valve G are effected by a three-way cock, I, placed in the pipe J, which constitutes the means of communication between the compartments B and D, the said cock I being operated by a lever, K, having attached to it a float, L, which rises and falls with the variation of level of the water accumulating in the trap. YVhen the waterlevel in the trap is low and the floatis in the position indicated at Fig. l, the chambers B and D are in communication through the pipe J, the cock L being in a position to allow free passage of steam, and the discharge-valve G is kept closed; but upon the water rising to the level indicated by the dotted line the cock I is by the action of the float L and lever K turned to a position in which such communication is closed and the compartment D is open to the atmosphere, the steam in said compartment escaping through the cock I and a branch pipe, J. The pressure upon the disk H being relieved, the valve G is opened and the water forced out of the trap until the level is reached, at which the float in sinking turns the cock I to close communication with the atmosphere and open communication between the compartments B and D. The valveGr being thereupon firmly closed, the discharge of water ceases.
Having now particularly described the invent-ion, what I desire to claim and secure by Letters Patent is- 1. In a steam-trap, the combination of the water and pressure chambers B D, the former provided with a discharge-valve, and having in it a float operating a cook or valve in a pipe communicating with the pressure-chamber, and the said chamber D having a disk or diaphragm bearing on the discharge-valve and acted on by variations of pressure produced by the operation of said cock, substantially as described.
2. In a steam-trap, the combination, with the disohargevalve, of the pressure-chamber I D, provided with a disk or diaphragm bearing on said valve, and a three-way cock, I, controlled by a float in the trap for operating the said valve, substantially as hereinbefore described.
3. The combination, with a casing having l ports, and a web with openings therethrough, I dividing said easing into compartments, a
valves in said openings adapted to be operated alternately by said diaphragm and float, for the purpose set forth.
In witness whereof I have hereunto set my I 5 hand and seal this 5th day of November, 1887. PETER FYFE. [1 s.]
