v STEAM-TRAP.
Specification of Letters Patent.
Patented Manie, 1920.
4Application filed May 6, 1918. l Serial No. 232,830.
T0 all 'whom t may concern Be it known that I, JOHN CALLiooTi, of the city of Toronto, in the county of York, in the Province of Ontario, in the Dominion of- Canada, have invented certain new and useful Improvements in Steam-Traps, and do hereby declare that the following is a full, clear, and exact description of same.
This invention relates to steam traps and has for its objects to provide, in a trap,-a construction adapted to simple manufacture and easy assembling, while being particularly reliable in operation, and to provide readily detachable baille means adapted to inclose a ball valve to prevent direct steam access thereto, and to act as a'guide for the said ball.
Further objects subsidiary to or resulting` from the aforesaid main objects, or from the construction and operation of the invention as it may be `carried into effect, will become apparent as the same is more par ticularly describedy hereinafter.
In carryin the said invention into effect, Iinay lprovic e a casing. having an inlet and an outlet and a valve seat at the said outlet, adapted to receive a ioat valve, and a further casing or structure comprising a cover or having a cover supplementary thereto, adapted to be inserted within the said rst mentioned casing, to divide the same into a plurality of compartments opening alternatively at their upper and lower ends, one into the other, the walls of the foremost compartment forming a guide for the valve and protecting the said valve from direct steam Vaccess' thereto; all of which is more particularly described and ascertained, 'by way of example, in the following description of the accompanying drawing, in which- Figure 1 is a vertical section of a steam trap for large installations, embodying my invention.
Fig. 2 is a sectional plan of the same, the section being taken on the line 2*-2", Fig. l, and the cover of the trap being shown as partly broken away, and- Figf is a section of a trap embodying my invention, suitable for smaller installations.
Similar characters of reference indicate similar parts in the several figures of the drawing. 0
1 is a body or an outer casing having an inlet 2 and an outlet 3, the outlet 3 extending upwardly Within the casing, as in a branch 4L, and terminating in a valve seat 5', which may be Vdetachable or otherwise, to
vpermit valve seats having various sizes of openings to be used according to the amount of water to be taken care of in the trap.
G is a ioat or valve effecting the normal closing of the outlet of the trap, Fig. 1 illustrating said valve as being of a compound nature, in which a smaller ball or valve proper, 7, is shown connected with the 'Hoat 6 of the valve by a chain 8, where it may be desired that the height of the Water required to raise the valve may be substantially above the valve seat. 9 are orifices in a valve casing 10, surrounding the said valve proper, 7, in the example shown in the said Figs.r 1 and 2.
11 is acasing adapted to insertion in the said casing 1 (in Fig. 3 being shown as flanged and threaded to provide a cover for thesaid casing 1, and in Figs. 1 and 2 as supplementary to a cover 12), the said casing 11 having a partition 13 extending down- Wardly around the valve .or float 6 and inclosing the saine, to provide a vertical guide for the said float,`the said partition 13 terminating within a .short distance of the base of the outer casing 2, whereby an'entrance 14; to the chamber inclosed by the said partition is provided; and `in Figs. 1 and 2 a further partition 15 is provided,
extending to the base of the said casing,'
which is orificed, asy at 16, near its upper end to provide an entrance to the chamber inclosed thereby.
The partition or partitions are readily removable upon, or with, the removal of the cover of the casing 1, and unobstructed access to the valve is thus permitted, as wellas to all parts of the interior of the said casing, which is desirable. The partition or partitions When in position insure the requisite water seal within the trap, the partition 13 also insuring correct reseating of the oat or valve after same has been lifted by the water within the chamber having risen to an extent eiiecting such opening lifting' ofv the said valve. The partition 13 also serves to protect the ball or float 6 from direct contact with steam or surges of steam, which might displace the said ball6 and thus permit undesirable escape of such steam through the outlet of the trap.
16 indicates an air outlet which may be provided to receive a petcock, or air valve, if thought necessary or desirable, and 17 and a removable cover 'for said casing 18 indicate recesses in the casing 1V adapted to contain gaskets, such for example as of lead, into comparatively sharp wedges 19 and 20, formed on the cover or on the lower edges of the partitions 15, may be co1npressed. Y u
This invention may be developed within the scope of the following claims without departing from the essential features of the said invention and itis desired that the specification and drawingbe read as being merely illustrative and not in alimiting sense, except as necessitated by the prior art.
vyl/That I claim as my invention is,- l. A steam trap comprising a. casing including a bottom and a. vertical tubular wall, Y g, a steam inlet orifice provided in the wall of the casing, a water outlet pipe connected to the cenplacing the upper ends of said chambers incommunication, a second tubularv baiiie arranged within the first baiie, surrounding said pipe and spaced away from the wall of the iirst baiile, said second baiiie forming a Y. chamber closed at the top and open at the bottom, and a float valve arrangedl within thev second bailie for normally effecting,thek
closing of the outlet orifice, said valve being guided by the second baile.
2. A steam trap comprising a closed casing having a steam inlet, a water outlet cony duit extending upwardly in said casing and having a flared upperend, ports provided in said conduit below its upper end and a valve extending upwardly in a branch within said Vcasmg, a valve seat in thev upper end of said branch, a iioat valve Vnormally eifecting the closing of said outlet, an inner casing insert- 4ed in said outer casing, said inner casing being 4closed at the upper end and having an outer tubular wall of smaller diameter than said outer casing andan inner. tubularwall of still smaller diameter, 'said'outer tubular wall being oriiiced at the upper end and forming, with said outer casing, inner Vand outer chambers, and said inner wall being open at the lower end and formin "a further chamber inclosing said outlet ori ce branch, and means securing said inner casing in position within said outer casing. j
