STEAM CLEANER Filed 5 1925i mfg/mmf?, A. LAR/60N Patented Mar. 25, 1930 UNITED STATES ALICK CLARXSON, OF STRATFORD, ONTARIO, MOTORS, LIMITED, OF STRATFORD, ONTARIO,

CANADA, ASSIGNOR TO BROOKS STEAM CANADA, A CORPORATION OF CANADA eraan emanan Application led October 3, 199B. Serial No. 310,096.

My invention relates to improvements in steam cleaners, and the object of the invention is to devise a simple means for removing particles of foreign matter from the 5 steam so that such steam will be free therefrom as it passes to the engine preventing the detrimental effect thereof in the steam cylinders and other parts of the engine, and it consists essentially of the arrangement anc 1o construction of parte as hereinafter more particularly explained.

Fig. 1 is a sectional view through my steam cleaner.

Fig. 2 is a plan sectionalview on line 22 15 Fig.

n the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates a cylindrical casing provided I with upper and lower heads 2 and 3. 4 is a clean out orifice in the lower end of the cylinder casing 1.

-5 is a ciylin rical member which de ends centrally rom the head 2 and is provi ed at 35 its lower end with an out turned annular inclined'tlange 6 forming a constricted annular opening 7 between t e lower edge of the flange and the internal periphery of the casing 1. 8 is a feed inle steam pipe leading tan entially into the casing 1 at its upper en'. The steam is fed under pressure through the pi e 8 into the casing and travels around suc casin between the internal eriphery thereof an the exterior of the cyindrical member the flange 6 tending to resist the Adownward passage of the steam so that a whirling action is provided forcing the steam outward against the interior periphery of the casing, the steam passing slowly down through the mouth7.

By this action the foreign particles in the 'steam which are the heavier particles are carried outward by centrifugal action against the internal surface ofthe casing and fall downward by gravity, the main body of the steam passing through the mouth is carried through the open end and perforated top of the vertical steam outlet pi e 9 which is secured in an orifice 10 terme in the lower 1 pacers 13 are provided to in the conical member 11.

head 3 of the casing in order to further resist the downward passage of the steam.

A hollow conical member 11 is carried by the outlet pipe 9 intermediatel ofthe height thereof and of the 1eight o the casing 1 so as to form a very small opening or passage between the periphery o such member and the internal peripher. of the casing. old the member in proper relation to the casing l. 14 are perforations formed in the u per portion of the conical member 11, an l5 is an annular baie flange carried the pipe withpasses downward through the passa Pe 12.9.1161 which serves also to carry the partie es downward when it has passed through such mouth passes u ward into the conical member 11 as t the aille plate 15 andv through the orifice 4 into the main llow of steam passing outward into the upper end ot the pipe 9.

The baiile plate 16 insures t iat no articles of foreign matter pass upward wit this out flowing steam. The particles of foreign matter passing downward'by gravity past the conical member 11 collect in the bottom of the casinghl and are cleaned out periodically throng the clean out orifice 4c.

lFrom this description it will be seen that I have devised a very simple device whereby all particles of foreign matter may be removed lrom live steam so as to render it more suitable 'for consumption.

What I claim as my invention is 1 A steam cleaner comprisin a cylindrical casing havin upper and ower ends, esteem. inlet pipe lea ing tangentiallv into the upper end of the casing, a cylindrical member deending centrally, from the upper casing cad to form an annular interspace between.

itself and the wall of the casing and having an out turned lower edge portion forming a constricted annular steam outlet Within the casing, a steam dischar e outlet leadin through the lower end o the easing, an means for bailling that ortion 0l.' the steam with the descending par icles of foreign mat ter to prevent the upward passage of such matter to the steam Outlet.

2. A steam cleaner, comprising a cylinlill e steam which drical casing having upper and lower heads,

a steam inlet lpipe leading tangentially into the upper end of the casing, a cylindrical y member supported centrally by the upper casing head to form an' annular interspace between itself and the wall of the casing and having an out turned lower edge portion forming a constricted annular steam outletwithin the casing, a steam discharge tube arranged axially within the casing and passing through the lower head thereof, and means carried by the tube for forming a constricted annular mouth between itself and the internal periphery of the casing and means for re- 4 turning the steam passing outward through such restricted mouth with the foreign particles of matter back into the main flow of steam passing through the upper end of the discharge outlet.

3. A steam cleaner comprising a cylindrical casing having upper and lower heads, means for feeding the steam tangentially into the upper end of the casing to'permit the foreign particles of matter contained in the steam to be carried out by centrifugal action against the inner periphery of the casing to pass downward and a steam discharge pipe extending centrally and longitudinally of the casing through the lower end thereof, a conical member carried by the steam discharge pipe intermediate of the height of the casing and forming an.annular constricted outlet between itself and the wall of the casing through which the particles of foreign matter are adapted to fall, and means for returning the steam passing downward with such particles of foreign matter into the main steam iow to pass outward through the discharge.' 1

4. A steam cleaner comprising a cylindrical casing having upper and lower heads, means for feeding the steam tangentially into the upper end of the casing to permit the foreign particles of matter contained in the steam to be carried out by centrifugal action against the inner periphery of the casing to pass downward and a steam 'discharge pipe extending centrally and longitudinally of the casing through the lower end thereof, a conical member carried by the steam discharge pipe intermediate of the height of the casing and forming an annular constricted outlet between itself and the wall of the casing. through which the particles of foreign matter arel adapted to fall yand having perforatiois in the wall thereof adjacent its upper en 5. A steam cleaner comprising a cylindrical casing having upper and lower heads, means for feeding the steam tangentially into the upper end of the casing to permit the foreign articles of matter contained in the steam to e carried out by centrifugal action againsty the inner periphery of the casing to pass downward and a steam discharge pipe exbetween itself and the wall of the casing through which the articles of `foreign matter are adapted to all and having'perforations in the wall thereof adjacent its upper end, and an annular flange carried' by the discharge pipe within the conical member.
