Application fled Kay 4, 1927. serial No. 188,688.

This invention has reference to washing machines and particularly to that type, in which is employed a centrifugal extractor for removing the free water from the clothin or other materials by centrifugal action, and ischarging such water onto a manually and circumferentially adjustable drain board for directing such water into the washing tub or other receptacle, and which also functions to catch the drippings from clothin or other materials assed from the tub or 0t er receptacle to said extractor.

The invention comprehends a housing mounted at the head of the extractor in a manner to adapt it to be manually and ciroumferentially adjusted about the extractor, whereby to selectively position the drain board over, and to direct water extracted from clothing or other materials, to the washing tub or other receptacle or receptacles; and it is the principal object of th1s 1nvention to provide a new and novel mountm for such housing whereby it is placeable an removable from its support in a predetermined yposition circumferentially of its support; means being provided to prevent wabbhng, rattling or chattering of t e housing on its support and means being also provided for locking the housing in difierent circumfer- 30 ential positions on its support.

That the invention may be more fully understood, reference is ha to the accompan ing drawings illustrating a preferred embo 1- ment of the invention, in which Fig. 1 is a plan view on a. greatly reduced scale, of so much of a ;washing machine, including the extractor, as will illustrate the embodiment of my invention, the housing and its drain board shown in full and dotted lines in two of its circumferential 1positions;

Like characters of reference denote corresIpondin parts throughout the figures.

n the rawings I have illustrated only so much of a washin machine including washing tub, centrifuga extractor and supporting frame as will show the practical embodiment of my invention. In Figures 1 and 2 there is illustrated by dotted hnes a receptacle to show the adaptability of my invention in the passage of clothing or other materials into the extractor from a washing tub and other receptacle and the discharge of water expelled from the extractor into such tub or receptacle.

The washing tub, only a part of which is shown, is designated 1 having a washing ele-. ment 2 adapted to be operated from a shaft 3 rotatably 10urnaled through the bottom of said tub. The head frame 4 forthe tub '1 terminates in a laterall extended rin -like extension 5 the axis 0 which while ing spaced at a suitable distance from one side of the tub is also ofi-set from a line extending transversely through the axis of the tub, whereb to position the extractor closer to one si e of the machine than the other for the convenience of the attendant in handlin the washing and drying operation. A stan ard or post 6 supports the extension 5. The legs or standards for the tub and connecting braces with the post 6 are omitted.

The ring-like extension 5 of the frame which supports the housin and drain board connected thereto and w ich is manual] and 'circumferentially adjustable thereon is formed or provided with a vertically disosed annular flange 7, the peripheral surace of which is tapered downwardly and inwardly, as at 8, see Figs. 2 and 6; with the exception that at predetermined, preferabl three points the peripher of this flange 1s cut-away, as at 9, to rovi e cut-awa or cutout portions of suita le length with s oulders 10 at the opposite ends of such cut-away or 110 cut-out portions. Such an arrangement of ring-like extension and flange produces or provides an annular shelf portion 11 encircling the flange 7 to provide a rest for the water conducting housing, to be described, and on which the same may be rotated.

The housing to which reference has been made is designated 12 and is best seen in Figs. 1, 2, 4 and 5, res ectively. Such housing is of suitable dept and circular in outline, being of outside diameter equal to the diameter of the ring-like extension 5 with bearing surfaces adapted to rest and rotate on the flange 7 and the shelf portion 11, see Figs 2 and 7. Said housing has an annular conduit 13, see Figs. 2 and 5, formed by 1ts vertical outside wall 14 in spaced relatlon to a comparatively short upstandinginner wall 15. The outslde wall 14 is formed wlth a depending apron 16 adapted to rest and rotate on the shelf portion 11, see Fig. 7, and the bottom 17- of the condu1t 13, at a point coincident with the base of the wall 15, see

also Fig. 5, is formed or provided with an annular shoulder or off-set 18 to overlap the flange 7, whereby the bottom 17 rests and rides on the top of said flange 7 with the apron 161 ing without and next adJacent the outside 0 the ring-like extenslon 5 and the shoulder or ofl-set 18 1 ing within and next adjacent the flange 7. n this manner and by this means the housing is seated and adapted to be rotated on the extension 5. The top of the housing is open, as at 19, and movable therein is a cover 20 for the extractor 21; said cover being rotatably connected to a support 22 hinged at one end to the housing, as at 23, while its opposite end is adapted to be locked against the housing, by suitable locking means 24. a

'In the form shown, the housing 12 is provided with a radially extended shelf portion 25, adapted through rotative movement which may be imparted to the housing 12, to be moved over the tub 1 or over a rece tacle A, indicated b the dotted lines in igs. 1 and 2. Over t is shelf portion clothes and other materials may be moved to deposit the same in the extractor 21, from either the tub I or the receptacle A, or vice-verse, and such shelf will catch drippings and direct the same into the tub 1 or the receptacle A. The shelf 25 is artitioned to provide a conduit 26 therewit in in communication with the conduit 13 of the housing and havin a discharge outlet, at its outer end, see ig. 4, whereby water expelled from the receptacle 21 into the conduit 13 of the housing may be discharged into the tub I or the receptacle A, as it is believed will be understood.

The receptacle 21, is of the usual taperedlike container used in machines of like character and is o ratively'connected .With an operating sha 27, adapted to be actuated from the same source 0 power, not shown,

bgr the rotation thereof, the water ex t e for operatingthe shaft 3 connected with the washing element 2. The n per end of the container or rece tacle 21 is so positioned in relation to the interior of the housing'12,

that through the centrifugal action setnls reby will overflowor be dischar e over the top thereof, over the wall 15 of t e housing 12 into the conduit 13 and be conducted thereby to the outlet within the shelf ortion 25 forming the drain board, and rom thence into'the tub 1 or the receptacle A.

Connected to the inner face of the apron 16 of the housing are a plurality of spacing and anti-rattling or anti-chatterin blocks 28, see Figs. 4 and 5. There are pre erably three of these blocks, which have mner tapered surfaces, as at 29 and their lengths conform to pr'are slightly less than the length of the cutaway or cut-out portions 9 in the flan e 7 of the housing. Preferably two. of t ese blocks are fixe 1y attached to the apron 16 bylthe removable screws 30 and the remaining block is preferably laterall movable through and by means of a 100 g screw 31, see Fi 4 and 5. These blocks are s aced from eac other circumferentially o the housing to correspond to the spacin of the cut-out or cut-awa portions 9 in the flange 7, so that when the ousin is made to overlie the extension 5 and the b ocks 28 and cut-out' ortions 9 are coincident, the housing may e dropped into assembled position on the extension 5 with the blocks 28 enterin the cut-out portions 9 between theshouldere ends 10, and by reason of the inner faces of said blocks havin the same taper as the peripheral surface 8 o the flange the housing may then be rotated on the e nsion 5 with the tapered faces'of the bloc and the tapered surface of the flange being next ad'acent. These blocks will prevent rattling or c attering of the housing'on its support during the rapid rotation of the container or receptacle 21. To lock the housing on its suppo in any of its ad'usted positions, the atten ant W1 1 turn up t e locking screw 31 forcing the block into impinging locking engagement with the flange 7. In Fig. 3 the dotted s1t1on of the shelf portion 25 of the housing shows the position it should be caused to assume when placing or removing said housing from its support.

The securin means for'the housin will prevent its accidental displacement m rovides a simple and convenient means o as sembly and a"means for fixing the same in adjusted positions, while providing for the easy removal of the housing for shipping puroses.

What I claim is In a centrifugal extractor, in combination a rotatable receptacle, a member supported to be manually and circumferentially adjusted about said receptacle for receiving water expelled thereby and for discharging such water at different points about said recep tacle, a support for said member havin an annular vertically disposed ring provided with a tapered periphery having cut-out portions at predetermined points, spacing and non-chatterin blocks carried by the memher and so positioned circumferentially thereof as to be movable in the cut-out ortions of said ring when placing said mem or on and removing the same from said support and said blocks having tapered surfaces correspondin to the taper of the surface of said ring an for preventing dislodgment of the member from its support when said tapered surfaces of the ring and blocks are co-adj'acent, and means co-acting with one of said blocks for locking such block in impinging relation with the ring of said support for securing said member in different circum- 20 ferential positions thereon.

In witness whereof, I have hereunto aflixed my hand this 30th da of April, 1927.

ALPHEU W. ALTORFER.
