STEAM-TRAP.

SPECIFICATION forming part of Letters Patent No. 758,725, dated May 3, 1904. Application filed January 18,1904. Serial No. 189,402. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY J. \VEssINeER. a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Steam-Traps; andl do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to steam-traps, and has for its object the provision of a trap in which the various parts are easily accessible for cleaning or repair.

WVith this and other objects in view it consists of a casing provided with a suitable head or cover, a tilting bucket mounted within said casing, and valves mounted in said head.

It also consists of certain other constructions, combinations, and arrangements of parts, as will be hereinafter described and claimed.

in the drawings, Figure 1 is a central vertical section through my said invention. Fig. 2 is a bottom plan View of one of the valves thereof. Fig. 3 is a top plan view of the cover forming part of said invention, and Fig. at is an elevation of an assembling-tool.

In the drawings, 1 is a casing provided with a cover 2. Pivotally mounted within said casing, as at 3, is a tilting bucket el, provided at its upper forward edge with a -lip 5, adapted when said bucket is raised to bear against a stop 6, formed upon the inner wall of said casing. The casing is further provided near its upper edge with an inlet-port 7 and a discharge-p0rt-8 and near its lower edge with a blow-oif or drainage-port 9. A deflecting-lug 10 extends from the wall across said poi-t7. On said cover is formed a housing 11, containing two valve- chambers 12 and 13, respectively. The lower end of said chamber 11 normally communicates with the upper end of the chamber 12 by means of a port 14, formed in said cover. Said chamber 12 is open at its lower end into the bucket chamber or reservoir 15, and the upper end of said chamber 12 is closed by a plug 16. The valve-chamber 13 is diametricallyreduced intermediate of its ends by a contraction of its walls, as at 17, and below said contraction communicates with a passage 18, which in turn communicates with said discharge-port 8. The lower end of said valve-chamber 13 is closed by a vertically-apcrturcd plug 19, adapted to form a seat for a valve 21, positioned in said chamber and reduced at its lower end, as at 21 and 21". A pipe 22 is secured at its upper end to said plug 19 and communicates with the aperture therein and extends downwardly into said bucket and nearly to the bottom thereof. Positioned within said chamber 12 is a balanced valve 23, diametrically reduced intermediate of its ends, as at 2%, and centrally apertured, as at 25. Depending from said valve are one or two transversely-apertured lugs 26, to which is pivotally secured the upper end of a link 27, which link is pivotally secured at its lower end to one or two transverscly-apertured lugs 28, extending upward from the bottom of said bucket. The upper end of the aperture in said valve 23 is preferably threaded to engage a suspending-rod 29, which may be used in drawing said valve 23 into said chamber 12 when assembling the parts of said invention, the rod 29 being removed after said valve is in position. Said chamber 12 from a point above and near the mouth of said port 1% communicates, through a port 30, (extending through a shoulder 31, formed on said housing,) with the passage 18, near said discharge-port 8. It will be observed that communication between said port 30 and said port 1% is normally cut off by the lower end of said valve 23, but that when said valve 23 is drawn downward by said bucket and link the port 14 will communicate with the port 30 through the passage or groove formed by the reduced portion of said valve. The upper end of said chamber 13 is closed by a plug 31, upon the inner end of which is formed a depending stop 31. The ports 7, 8, and 9 are internally threaded to receive pipes 7, 8, and 9, respectively. Said pipes 7 and 9 are preferably provided intermediate of their ends with cut-off valves (not shown) of any suitable construction for the purpose of arbitrarily closing said pipes when not desired for use, said valves being well known to the art and not thought necessary to be shown or particularly described herein.

Inoperation the chamber 15 is preferably partly filled with water through an aperture in said casing or cover, which is then closed by a plug 32. Steam and water then enter said trap through. the port 7 the water being deflected down by said lug 10 and collecting in the chamber 15. The steam circulates freely in said chamber 15 and passes through the aperture in the valve 23 to the chamber above the same and also through the port 14 to the chamber above the valve 17, at the same time pressing upon the lower end of said valve 23 and also entering through the pipe 22 and pressing against the reduced end of said valve 21. The water collecting in the chamber 15 will eventually rise around said bucket and flow over the top of the same, filling said bucket and tilting it down, in which movement the bucket will draw down the valve 23. As the reduced portion of the latter valve passes the mouth of the port 14 the steam will escape from above the valve 17 through the port 14 and the passage around said reduced portion 24 and through the passage 30- and 18 and through the port 8, this relieving the pressure above said valve 17, which is thereupon lifted by the water forced upward in said pipe 22 by the steam-pressure above the water in the bucket. Said water then'escapes under steam-pressure through the passage 18 and port 8 until said bucket is substantially emptied, whereupon the bucket is raised or floated again by the water surrounding it. The valve 23 simultaneously rises, uncovering the port 14, and steam passes to the chamber above the valve 17 thus closing said valve. It should be observed that said valve 23, after establishing communication between the passage 30 and the port 14, continues to descend until the passage 30 is again closed by the upper end of said valve.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a steam-trap, the combination of a reservoir provided with an inlet-port, a clownwardly-tiltable bucket positioned in said reservoir, a cover for said reservor having suitable valve-chambers and suitable ports formed therein, a balanced valve positioned in one of said chambers and adapted to govern some of said ports and connected with said bucket by a connecting link or rod pivoted at one end to said valve and pivotally connected at the opposite end to said bucket, and a valve positioned in the other of said chambers and adapted to govern another of said ports, substantially as described.
