To (ZZZ whom it may 'coaoem Be it known that I, GEORGE Tnnmiam a citizen "of the United States, residing --at "lVorcester, in *the county of Worcester and State ofMassachusetts, have invented certain new and useful lmpr'ovemerrts in Steam- Strain'ers, of which the following is a speciof steam turbine rotors. vaiious'dilferently constructed devices have beenl eretoforeidevised for the purpose orsep araftin'gparticles of foreigumatter "froimsteam'g therefore it is not intended "to incluc'lefbroadly,"devices of substantially different construction as within the scope'of'the "invention herein claimed.
"The object of mypre'sent'invention "is to provide a practical, desirable and ellicient steam s'trainingappliance of peculiar compact construction; simple and economical for manufacture; conveniently applicable to use, adapted for a' straight away connection with the steam conducting pipes; and requiring but a comparatively small space for its occupancy in practice.
'These objects I attainby the'peculia r construction illustrated in the drawings and hereinafter explained in detail. I
'Inlthe accompanying drawings, Figure '1 represents an e'levation view-ofmy improved steam strainer. Fig.2 is along'itudinal central section of the same. Fig. 3 is a top end view; and Fig.4cis .a transversehorizontal section at line X X on Fig. 2.
This improved steam strainer consists of a straight hollow cylindricalbody-shell of cast metal (preferably bronze) of the required thickness; each of its ends being somewhat reduced or curved inward, as at 3, and provided with an integral wrench-receiving hub or polygonal end portion 4, having the inlet opening 5 and outlet opening 6 therein in coincident alinement with the axis of the body cylinder; said opening being internally threaded for the reception of the screw-threaded ends of steampipes I and Q. The openings are preferably of the same dimension :at each end of the body.
W-ithin the body cylinder 2 and cast integral therewith, at a position somewhat I above the lower end of the chamber, there is a pocket or receptacle 310, --preferably of :quadrant shape and of less diameter than the interior of the body. 'The mouth of said pocket is open atthe top and is provided with "an annular ledge "7 and surrounding lip or rim 9 axially and diametrically approximately coineiding'with the opening 5 inthe upper end of the shell. The lower end of said pocket a clean-out opening 8 that extends laterally outward through a suitable boss-'12 at the side of the cylinder, and is closed by a removable screw-threaded stopper or plug'13, fitted therein and adapted "to'beturnedby awrench; orif Preferred by .a'thumb piece formed upon the stopper.
T-he clean-out opening-may be nearly the size of-theinterior diameter of the pocket.
Ample clearance space 15 for the flow of steam is provided between'the wall of the pocket andthe cylindrical shell "2, anda full circular chamber is "provided below the pocket andad jacent the outlet opening =6.
A cylindrical tubular strainer 16 formed of perforated or foraminated sheet metal (preferably bronze) or other'suitable screen material, is arranged *between the "lower "p art of the upper end opening 5 and the top of the sediment pocket 10. fThe diameter of said strainer cylinder is of such dimension as will pass through the threaded opening 5 and'fit 'Withinthe rim 9 of the pocket, its lower end seating upon the ledge 7 while its upper'end fits the opening '5, or within the bore of a circular "flange '17 formed on the interior of the shell, just below the end of the screw-threaded portion. The opening 5 in Itheshell may be bored or reamed out with a .toolof the required size, the end of which is suitably formed and adapted to extend down to the pocket for dressing off the face of the ledge 7 and interior of the rim 9. The strainer 16 can be readily inserted and withdrawn through the threaded opening 5, but is retained securely in its proper position .when the end of a steam pipe I is screwed into the shell, as when the device is attached for service.
Sufiicient annular space 20 is provided,
between thestrainer cylinder 16 and the in terior of the body cylinder 2, so that steam top end of the strainer cylinder 16, in a' manner to project any sediment of foreign substance into the pocket 10 while the steam passes laterally through the perforated strainer cylinder into the annular space 20, betweenthe strainer and shell 2, and thence to the outlet opening 6 and pipe 0 connected thereto. Should any sediment lodge upon the strainer the inflow of steam tends to drive it therefrom into the pocket.
This device is applicable for straining other elastic fluids than steam. It is especially useful in connection with elastic-fluid turbine motors for protecting the nozzles and bladings from becoming clogged, or injured by accumulations of grit and sediment.
This steam strainer device is so designed and organized that the steam inlet and steam outlet are in axial alinement with the cyliir drical body-shell, the axis of the tubular strainer and the mouth of the sediment pocket; thus forming a straight-away connection with the steam pipes at either end, so that the steam flow is practically in one direction; thereby eliminating unnecessary loss incident to turns and bends. strainer tube is self cleaning; foreign matter coming in with the steam is discharged downward as the steam passes laterally through the apertures of the strainer, therefore the particles can not stay in suspension to clog the holes of the strainer, since the velocity through the holes of the strainer tube is so low in comparison with the entrance velocity of the steam that the foreign matter must deposit in the receiving pocket.
Deposited matter may be removed from the pocket upon removal of the clean-out stopper 13, and may be positively and quickly ejected by allowing steam to pass through so as to blow out the collected material. The body-shell being of comparatively small dimension, and of the form shown, can be conveniently connected with steam pipes where the adjacent space is limited, or in close relation to other obstructions.
The
What I claim is 1. A steam strainer consisting of a hollow cylindrical body having an inlet and outlet in its ends respectively in axial alinement, said body provided internally with an integral pocket having a concentric upper opening and seat, its lower end extending through the side of the body and closed by a removable stopper, and an interior perforated tubular screen extendlng from the inlet-opening to the top of said pocket, with an annular space within said body surroimding said screen and communicating with th outlet opening.
2. In a device of the class specified, a straight cylindrical body-shell inwardly curved at its ends and provided with wrench-receiving hubs having inlet and out-- let openings screw-threaded for attachment to pipes in coinciding axial alinement, said body provided internally with a sediment receptacle formed integral therewith and opening laterally through the side of the body cylinder, the mouth of said receptacle having an annular ledge and rim-flange c011- centric with the body-shell, a tubular strainer passable through the inlet opening and disposed with its lower end fitting within said rinrfiange and supported upon said ledge at the mouth of said receptacle, the upper end of the strainer fitting within the bore of a flange at the top end opening of the body, said strainer being axially in alinement, therewith.
3. In a device for the purpose specified, a cast metalshell consisting of a cylinder having polygonal hubs at its ends each with a screw-threaded opening therethrough, said shell internally provided, at a position some what above its lower end, with an integrally formed quadrant-shaped pocket having an upwardly directed mouth and annular seating-rim approximately corresponding in size and in coincident axial alinement with the end openings, the lower end of said pocket opening through the side of the cylinder and provided with a screw'threaded stopper, and an internal foraminated cylinder having its respective ends supported by said seatingrim and within the inlet opening axially concentric with the main cylinder.
lVitness my hand this seventh day of December, 1918.
