CLOTHES-WASHING MACHINE Filed Jan. 14, 1950 IN VEN TOR.
George P. Cqsmer BY M, (964% W Patented Mar. 10, 1953 UNITED STATES PATENT OFFICE CLOTHES-WASHING MACHINE George P. Castner, Webster City, Iowa Application January 14, 1950, Serial No. 138,597
6 Claims. 1
The present invention relates to clothes washing machines, and more particularly to improved clothes washing machines of the character of that disclosed in the copending application of George P. Castner, Serial No. 85,113, filed April 2, 1949, now Patent No. 2,596,980 of May 20, 1951.
Fundamentally the clothes washing machine disclosed in the Castner application mentioned comprises an upstanding tub formed of sheet metal and having connected front and rear and side and bottoms walls providing an open top, the bottom wall being substantially semi-cylindrical and extending between the lower portions of the side walls. A substantially disk-like dasher is mounted in an upstanding position directly upon the rear wall for rotation about a center substantially concentric with the arc of the bottom wall, the dasher being rotated unidirectionally. The dasher comprises a relatively shallow outstanding vane on the front face thereof that projects into the tub, the vane being removed from the center of rotation of the dasher and extending in a crosswise to radial direction with respect to the center of rotation of the dasher. The dasher occupies a submerged position in the wash liquid suspending the clothes and contained in the tub. This arrangement of the vane causes the dasher lightly to engage and pull the clothes by an angular sliding contact therewith and then quickly to discharge the clothes in order to move and to rearrange the clothes in a substantially upstanding circular path in an active area in the wash liquid disposed adjacent to the rear wall of the tub. Thus in the operation of this machine, and in accordance with the method thereof, the clothes ride the dasher intermittently in a relatively small substantially upstanding circular path disposed within and adjacent to the bottom of the first mentioned circular path, which arrangement is highly desirable in that the riding of the dasher by the clothes i productive of a vigorous washing action upon the clothes in order to loosen dirt and other soil therefrom; whereby the clothes are thoroughly cleansed.
However, in this machine the riding of the dasher by the clothes is not altogether uniform throughout the mass of the clothes; and the time interval during which a particular garment or garments ride the dasher is subject to considerable variation.
Accordingly, it is a general object of the present invention to provide an improved clothes washing machine of the general character of that described that is so constructed and arranged that Cir Another object of the invention is to provide in a clothes washing machine of the type noted, a
dasher that embodies an improved arrangement for circulating the wash liquid in the associated tub in order to cause the clothes to be moved into the dasher and to be rearranged in the tub so as to obtain a thorough and uniform washing of the clothes.
Another object of the invention is to provide in a clothes washing machine of the type noted, a dasher that embodies an improved arrangement of shallow vanes upon the front face thereof for engaging and moving the clothes first toward and then away from the center of rotation of the dasher.
Another object of the invention is to provide in a clothes washing machine of the type noted, an improved arrangement of an upstanding disk-like dasher mounted for rotation upon one wall of the associated tub and of an upstanding baflle mounted upon the opposite wall of the tub in order toinsure positive circulation of the wash liquid from all parts of the tub into the rotating dasher.
A further object of the invention is to provide in a clothes washing machine of the type noted, a dasher of improved and simplified construction and arrangement.
Further features of the invention pertain to the particular arrangement of the elements of the clothes washing machine, whereby the aboveoutlined and additional operating features thereof are attained.
The invention, both as to its organization and method of operation, together with further objects and advantages thereof, will best be under-' stood by reference to the following specification taken in connection with the accompanying drawing, in which Figure 1 is a plan view, partly broken away, of a clothes washing machine em-,
bodying the present invention; Fig. 2 is a longitudinal sectional view of the machine, taken in the direction of the arrows along the line 2-2 in Fig. 1; Fig. 3 is a transverse sectional view of the machine, taken in the direction of the arrows along the line 33 in Fig. 1; Fig. 4 is another transverse sectional view of the machine, taken in the direction of the arrows along the line 4-4 in Fig. 1; Fig. 5 is an enlarged view of the front face of the dasher incorporated in the machine 3 shown in Figs. 1 to 4, inclusive; Fig. 6 is an enlarged view of the side of the dasher shown in Fig. and Fig. 7 is an enlarged view of the rear face of the dasher shown in Figs. 5 and 6.
Referring now to Figs. 1 to 7, inclusive, of the drawing, there is illustrated a clothes washing machine ID of the general character of that disclosed in the previously mentioned Castner application and embodying the features of the present invention. The machine It] comprises an upstanding tub II including front and rear walls I2 and 13, side walls It and I5, and a bottom wall I6. The front and rear walls I2 and I3 are arranged in opposed spaced-apart relation, and similarly the side walls I4 and I5 are arranged in opposed spaced-apart relation; whereby the tub II is provided with an open top substantially rectangular in form and narrower between the walls I2 and I3 than between the walls I4 and I5. Preferably the side walls I4 and I5 and the bottom wall It are formed from a single sheet of material, the bottom wall I6 curving between and extending into the side walls I 3 and I5. Specifically, the front and rear walls I2 and I3 are respectively provided with outwardly directed boundary flanges I1 and I8 around which the sheet defining the side walls 14 and I5 and the bottom wall I6 is wrapped and secured in place by electric resistance line welding, or the like. Further, the upper edges of the side walls It and I5 respectively terminate in outwardly and downwardly rolled rims I9 and 23 lending rigidity to the tub II. Preferably the bottom wall I6 is disposed along an are having a center that is coincident with the longitudinal center line of the tub II as illustrated at 2|; whereby the bottom Wall I6 is substantially semi-cylindrical.
A substantially centrally disposed upstanding hollow baffle 22 is secured to the inner surface of the front wall I2 and projects upwardly from approximately the longitudinal center line 2| of the tub I I to a position disposed somewhat below the open top of the tub II and somewhat above the normal level of the wash liquid contained in the tub II as indicated at 23. Further, the baffle 22 projects from the front wall I2 toward the rear wall I3 into the wash liquid contained in the tub II and is employed for a purpose more fully explained hereinafter. Of course, the tub II is liquid-tight; and the wash liquid may be supplied thereto in any suitable manner. A drain fixture 24 is provided in the lowermost portion of the bottom wall and is connected to a flexible drain hose, not shown, so that the wash liquid may be selectively retained in the tub II and drained therefrom. Preferably the walls of the tub II, as well as the baffle 22 and the drain fixture 24, are formed of a corrosion resistant material, such, for example, as stainless steel; and the parts are retained in assembled relation by electric welding, or the like.
An inwardly directed substantially annular emboss 25 is formed in the rear wall I3 in order to provide a substantially circular recess 2'6 surrounded thereby, the centers of the emboss 25 and of the recess 26 being substantially coincident with each other and with the longitudinal center line 2| of the tub I I. A substantially disklike dasher 21 is arranged within the circular recess 26 and mounted upon the front end of a drive shaft 28 that extends through the central portion of an outwardly directed centrally located counteremboss 29 provided in the base 30 of the circular recess 26, the base 36 of the circular recess 26 being disposed somewhat rearwardly of the rear wall I3 in order to accommodate the dasher 21 and to provide a thin substantially annular space 3| therebetween. The drive shaft 28 is supported and journalled for rotation in bearing structure including complementary sections 32 and 33 respectively disposed interiorly and exteriorly of the base 33 of the circular recess 26 and consequently of the rear Wall I3, whereby the sections 32 and 33 provide a liquid-tight joint preventing the escape from the tub II of wash liquid along the drive shaft 28. The rear end of the drive shaft 28 carries a pulley 34 rigidly secured thereto, whereby the drive shaft 28 and the dasher 21 may be rotated unidirectionally.
Referring now more particularly to Figs. 5 to '7, inclusive, the substantially disk-like dasher 21 has a substantially centrally disposed hole 35 formed therein that receives the front end of the drive shaft 28, the hole 35 being surrounded by a substantially semi-spherical or bulbous boss 33 provided on the front face of the dasher 21 in order to lend strength thereto. Also, the front face of the dasher 21 carries three relatively shallow outstanding vanes 31, 38 and 39, the vanes 31 and 33 being disposed on opposite sides of the center of rotation of the dasher 21 and the vane 38 being disposed in an intermediate position with respect to the vanes 31 and 39. Thus the vanes 31, 38 and 39 are disposed in angular spaced-apart relation with respect to each other and removed from the center of rotation of the dasher 21 and extend in acrosswise to radial direction with respect to the center of rotation of the dasher 21. Each of the vanes is tapered between the leading and trailing ends thereof with respect to the direction of rotation of the dasher 21. As illustrated, the dasher 21 is rotated in the clockwise direction; and the vanes are provided with leading and trailing ends respectively marked L and T. The vanes 31 and 38 perform a first function of engaging and moving the clothes in the tub II toward the center of rotation of the dasher 21, while the vane 39 performs a sec ond function of engaging and moving the clothes in the tub II away from the center of rotation of the dasher 21. Accordingly, the leading ends L of the vanes 31, 38 and 39 are disposed closely adjacent of the front face of the dasher 21, while the trailing ends T of the vanes 31, 38 and 33 are disposed in spaced relation to the front face of the dasher 21; which construction produces the actions noted, since the leading ends L of the vanes 31 and 38 are disposed more remote from the center of rotation of the dasher 21 than are the trailing ends T thereof, while the leading ends L of the vane 39 is disposed closer to the center of rotation of the dasher 21 than is the trailing end T thereof.
As a constructional example, the diameter of the dasher 21 may be 5 /8 inches; the leadin ends L of the vanes 31, 38 and 39 may be in the plane of the front face of the dasher 21; the trailing ends T of the vanes 31 and 33 may be spaced forwardly inch from the plane of the front face of the dasher 21; and the trailing end T of the vane 39 may be spaced forwardly fs inch from the plane of the front face of the dasher 21. The leading end L of the vane 31 may be positioned approximately /8 inch inward- 13' from the perimeter of the dasher 21 the trailing end T of the vane 31 may be positioned approximately inch inwardly from the perimeter of the dasher 21; and the vane 31 may curve substantially uniformly between the leadin and trailing ends L and T thereof. The leading end L of the vane 38 may be positioned approxi-.
mately inch inwardly from the perimeter of the dasher 21; the trailing end T of the vane 38 may be positioned approximately 1%; inches inwardly from the perimeter of the dasher 21; and the vane 38 may curve substantially uniformly between the leading and trailing ends L and T thereof. The leading end L" of the vane 39 may be positioned approximately 1% inches inwardly from the perimeter of the dasher 21; the trailing end T of the vane 39 may be positioned approximately inch inwardly from the perimeter of the dasher 21; and the vane 39 may curve substantially uniformly between the leading and trailing ends L and T thereof. The vanes 31, 38 and 39 may be approximately 1% inch wide and may occupy substantially the relative positions illustrated in Fig. 5. A slight bevel indicated at 4B is provided on the front face of the dasher 21 adjacent to the perimeter thereof; and a plurality of series of holes 41 are provided through the dasher 21 between the front and rear faces thereof. As illustrated, three angularly spaced-apart holes 41 are provided exteriorly of the vane 31, and six angularly spaced-apart holes 4| are provided interiorly of the vane 31; six angularly spaced-apart holes 41 are provided exteriorly of the vane 38, and three angularly spaced-apart holes 4| are provided interiorly of the vane 38; three angularly spaced-apart holes 41 are provided exteriorly of the vane 39, and three angularly spaced-apart holes 41 are provided interiorly of the vane 39. The holes 4| may be of 1%; inch diameter and may occupy substantially the relative positions illustrated in Figs. 5 and 7. Finally, the rear face of the dasher 21 carried four substantially equally angularly spaced-apart shallow blades 42 extending from a substantially centrally disposed hub 43 to the perimeter thereof. The blades 42 may project rearwardly approximately /8 inch from the rear face of the dasher 21 and may be approximately 1% inch wide. Preferably the dasher 21 is of onepiece construction, being cast from aluminum, or the like.
Also, in this constructional example the radius of the arc of the bottom wall 16 from the longitudinal center line 21 of the tub may be '1 inches; and the distance between the open top of the tub H and the longitudinal center line 2| thereof may be 8 inches. The distance between the front and rear walls 12 and I3 may be inches; and the distance between the side walls l4 and may be 14 inches. The normal wash liquid level 23 may be disposed approximately 2 inches below the open top of the tub I 1.
Considering now the operation of the machine Ill, the dasher 21 is rotated unidirectionally in the clockwise direction as viewed from the front face thereof, and may be rotated at a speed of approximately 400R. P. M. When the dasher 21 is thus rotated the shallow blades 42 carried upon the rear face thereof propel the wash liquid radially from the longitudinal center line 2| in the thin annular space 3| between the rear face of the dasher 21 and the base 30 of the circular recess 26, whereby the wash liquid is projected outwardly over the annular emboss into the tub I and is then drawn back into the front face of the dasher 21 along the longitudina1 center line 2|, and thence passes through the holes 4| provided in the rotating dasher 21 and back into the thin annular space 3|.
Thus the wash liquid is constantly recirculated by the rotatingdasher.
21 in the tub 11. As illustrated in Fig. 1, two horizontal components of the current of wash liquid are projected outwardly from the annular emboss 25, as indicated at 5| and 52; and as illustrated in Fig. 2, two vertical components of the current of wash liquid are projected outwardly from the annular emboss 25, as indicated at 53 and 54. The component 5| is projected toward the junction between the side wall 14 and the front wall 12 and then turns along the front wall 12 toward the adjacent side of the baffle 22 and again turns adjacent to the longitudinal center line 2| toward the front face of the dasher 21; and ultimately the component 5| passes through the holes 4| provided in the rotating dasher 21 into the thin annular space 3| in order again to be projected by the blades 42 carried by the rear face of the rotating dasher 21. The component 52 is projected toward the junction between the side wall 15 and the front wall 12 and then turns along the front wall 12 toward the adjacent side of the baffle 22 and again turns adjacent to the longitudinal center line 2| toward the front face of the dasher 21; and ultimately the component 52 passes through the holes 4| provided in the rotating dasher 21 into the thin annular space 3| in order again to be projected by the blades 42 carried by the rear face of the rotating dasher 21. The component 53 is projected toward the junction between the bottom wall I6 and the front wall 12 and then turns around the front wall 12 below the baiiie 22 and again turns adjacent to the longitudinal center line 2| toward the front face of the dasher 21; and ultimately the component 53 passes through the holes 4| provided in the rotating dasher 21 into the thin annular space 3| in order again to be projected by the blades 42 carried by the rear face of the rotating dasher 21. The component 54 is projected toward the junction between the normal wash liquid level 23 and the front wall 12 and then turns along the front wall 12 into the baffle 22 and again turns adjacent to the longitudinal center line 2| toward the front face of the dasher 21; and ultimately the component 54 passes through the holes 4| provided in the rotating dasher 21 into the thin annular space 3| in order again to be projected by the blades 42 carried by the rear face of the rotating dasher 21. Of course, since the dasher 21 is rotating in the clockwise direction, as viewed from the front face thereof, the components 5|,
52, 53 and 54 of the wash liquid illustrated have a clockwise rotative component so that the wash liquid is, in fact, swirled in the clockwise direction incident to its movement described above.
Also, the rotation of the vanes 31, 38 and 39 provided on the front face of the dasher 2'1 effect some rotation of the wash liquid in the clockwise direction, as viewed from the front of the dasher 21, the action of the vanes 31, 38 and 39 upon the wash liquid being generally complementary to that of the blades 42.
Accordingly, the clothes in the tub I I are moved or sucked along the longitudinal center line 2| into the front face of the dasher 21, whereby the vanes 31, 38 and 39 produce an engaging, pulling and moving action thereupon. Specifically, the vanes 31 and 38 gently engage the clothes by an angular sliding contact therewith and move them toward the longitudinal center line 2 5, while the vane 39 gently engages the clothes by an angular sliding contact therewith and moves them away from the longitudinal center line 2 1. Thus it may be said that the vanes 31 and 38 engage the clothes and deflect them t oward the longitudinal center line 2I, while the vane 39 engages the clothes and plows them away from the longitudinal center line 2|. More particularly, these correlated actions of the vanes 31, 38 and 39 provided on the front face of the dasher 21 cause the clothes to ride the front face of the dasher 2'! during the short time interval that the clothes are in contact with the front face of the dasher 2? and then to be projected or discharged from the dasher radially toward the periphery of the dasher 2? and back into the moving currents of wash liquid that are circulated in the tub I I. Accordingly, the clothes that are suspended .in the wash liquid contained in the tub I I move in a substantially circular upstanding path as indicated by the dotted lines 6 I, and also in a smaller substantially circular upstanding path as indicated by the dotted lines 82,, the paths 6i and 62 being arranged in an active area of the wash liquid positioned adjacent to the rear wall I3 and to the dasher 21. More particularly, the clothes move rather slowly in the path 6! in the clockwise direction, as viewed toward the front face of the dasher 21, until an individual garment or garments are grasped by the front face of the dasher 27 and whirled rapidly in the path 62. After a garment or garments are whirled rapidly in the path 62 as a consequence of riding the dasher 21, the garment or garments are quickly discharged from the path 62 back into the path 6|. Accordingly, it will be understood that a garment moving in the path GI at a relatively slow rate is seized by the front face of the dasher 21 and rotated in the path 62 at a relatively high rate and is then quickly discharged from the path 62 back into the path 6|. The rate of movement of the clothes traveling in the path 6| and the rate of movement of the clothes traveling in the path 52 are substantially uniform; and the time interval during which a garment or garments are riding the dasher 21 is substantially uniform. of course, the clothes moving in the path BI are worked in and out upon themselves and are rearranged constantly as the clothes traveling in the path El weave back and forth adjacent to the front face of the dasher 2'? during its rotation. It will be appreciated that the path .52 is disposed within the lower portion of the path GI and that while the path 62 is substantially circular the path Si is only generally circular as it has a tendency to become elliptical.
In the operation of the machine I the balile 22 prevents inordinate swirling of the whole body of wash liquid in the clockwise direction, as viewed toward the front of the dasher 21, since the baffle 22 projects considerably into the tub I I; the projection of the baflle 22 from the front wall .12 into the tub H being approximately 2 inches in the constructional example previously noted. Moreover, the bafiie 22 prevents the components BI and 52 of the current of the wash liquid from interfering with each other and the consequent tendency of the clothes suspended in the wash liquid from being pocketed adjacent to the central portion of the front wall I2. Accordingly, the baffle 22 cooperating with the rotating dasher 2i insures substantially uniform circulation of the wash liquid in the tub I I and the consequent constant rearrangement of the clothes suspended in the wash liquid, whereby all portions of the clothes are substantially uniformly and thoroughly cleansed.
Further, in the operation of the machine [0 the current of wash liquid that is projected outwardly from the thin annular space 3] over the annular emboss 25 by the rotating dasher 21 positively prevents the clothes suspended in the wash liquid in the tub II from working behind the dasher 21 into the circular recess 26., thereby preventing damage to the clothes and particularly the breaking of buttons from the clothes. Specifically, this substantially annular current of wash liquid issuing over the annular emboss 25 has a tendency to pocket the clothes adjacent to the front face of the dasher 21 so that the clothes may be drawn into the front face of the dasher 21 by the circulation of the wash liquid through the openings 4| provided through the dasher 21 in the manner previously explained, whereby the vanes 31, 3B and 39 provided on the front face of the dasher 2! may readily engage and move the clothes toward and then away from the longitudinal center line 2| and then quickly discharge the clothes from the path 62 back into the path GI, all in the manner previously explained.
In view of the foregoing it is apparent that there has been provided a clothes washing machine of compact, rugged and economical construction and arrangement that is efficient and simple in operation.
