ISAAC SHlMVVELL MCDOUGALL, OF IRK VALE, OHADDERTON, AND THOMAS SUGDEN, OF OLDHAM, COUNTY OF LANCASTER, ASSIGNOBS OF ONE- THIRD TO JAMES THOMAS MCDOUGALL, OF LONDON, ENGLAND.
STEAM-TRA P.
SPECIFICATION forming part of Letters Patent No. 368,101, eaten August 9,1887.
Application filed April 11, 1887. Serial No. 234,493. (No model.) Patented in England May 21, 1885, No. 6,350.
To all whom it may concern.-
Be it known that we, IsAAo SHIMWELL MCDOUGALL, manufacturing chemist, and THOMAS SUGDEN, mechanical engineer in the employ of McDougall Brothers, subjects of the Queen of Great Britain and Ireland, and residing, respectively, IsAAc SHIMwELL Mo- DOUGALL at Irk Vale, Chadderton, near Manchester, and THOMAS \SUGDEN. at Greengate I@ Street, Oldham, both in the county of Lancaster, England, have jointly invented certain new and useful Improvements in Steam-Traps or Apparatus for Separating Water or other Liquids from Steam-Vapors or Gases, (for I 5 which we have obtained a patent in Great Britain, dated May 23, 1885, No. 6,350,) of which the following is a specification.
This invention has for its object to provide a strong, effective, simple, andV cheap steamtrap or apparatus for the separation of water or other liquids, from steamlvapors or gases in such a manner vas to eli'ect the separation au- Y tomatieally, the said trap or apparatus being readily adjustable and being provided with an arrangement for testing the apparatus while at work for clearing the valve and seatings of dirt and grit and for the discharge of air.
Wve will describe the invention with reference to the accompanying drawings, which v3o represent,v in Figure l, a section of an apparatus constructed according thereto, and in Fig. 2 a sectional elevation of a modified form of outlet-valve.
A is the vessel or casing in which the water laccumulatea the said vessel having in its interior a fulcrum-pin, a2, carried by the standard a, or otherwise, on which fulcrum is mounted a lever, B, having at one end a piece,
C, of light specific gravity, and preferably l4o solid, which we will call a iloat, and at the equilibrium-valve, as shown, is between the 5o upper and lower members of the valve, for the convenience of outlet. The valve is connected to the lever B at the same endv as that to which the oat C is attached. The `float C may be, with advantage, of a material such 5 5 as earthenware. The float is counterweighted by the weight D, which may be, for example, of iron or lead. The vessel A is provided with a suitable inlet, A3. The position of the weight D and float C on the lever B is such as to'lreep 6o the valve E closed when there is no water in the vessel A, or when there is only a predetermined 4 amount of water therein-*that is, the oat exerts a greater pressure on the valve in one direction than the weight exerts in the other direction. i
The iloat C and weight D are preferably so arranged that the iioat C only is immersed in the water in the vessel, the weight D being situated above the waterlevel, as shown clearly 7o in the drawings. If steam` only be admitted into the vessel, t-he valve is not affected, owing to the pressure of the steam acting on equal and opposite surfaces. When, however, water enters the vessel A, the valve E becomes immersed Iin water; but no action takes place un- 'til the water rises to a certain level, say, sufciently high to nearly immerse the float C, whichthen loses its downward force and the opposed weight D raises the iioat, and with it 8o the valve E, which then allows the water to be discharged through the outlet A2. This continues until the wat-er has nearly left the float C, when the said float regains its power over the weight D, and consequently the valve 8 5 E is again closed, although the valve is still immersed in water, so that the water is discharged without loss of steam.
A testing-rod, G, works through a gland or the likein the vessel A, the bottom part, g, of 9o the rod inside the vessel when testing coming into contact with the lever, or, as illustrated, the weight D thereon for opening the valve E, for blowing off, and by this means the valve i and seating arecleared of dirt without taking oi' the cover or detaching the valve or seating. A bracket, h, is fixed on the casing A, and is provided with a stop-peg, h2, and snitable holes are'provided in the test-rod G, so
that the valve may be kept open to allow the escape of air when steam isjust turned in, so as to avoid excessive pressure ,due to expansion of air or gases.
The arrangement in Fig. l shows valves resting on seat-ings; but we do not limit ourselves to that form of valve. Fig 2 shows a Inodcation, in which piston-valves are used which are guided by the wing-pieces beneath.
Although we have described the apparatus as vused for the separation of water from steam, it will be evident that it is applicable for t-he separation of liquids from vapors or gases generally.
Having now described and particularly ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what We claim is- The combination, with the vessel A, having passage A2, of the pivoted lever B, provided at opposite ends with weight D and iioat C, the outlet-valve connected to said lever, and the testing-rod G, under the arrangement and for operation as hereinbefore set forth.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
