16 Claims. (Cl. 68-2' This invention relates to an improvement in laundry washers and'more particularly to a iurther development oi' the type of washer shown in my copending application Serial No. 224.721, iled 6 August 13, 1938.

Such a washer includes a perforate drum mounted for rotation in a housing, the articles to be washed being placed in the drum and the V housing containing water which enters the drum 1 0 through the perforations in the walls thereof. The direction of rotation of the drum is usually changed several times during the washing treatment. As the result of the rotation the water in the housing is moved peripherally of the drum 15 and 'transversely of the housing, ilrst in one direction and then in the opposite direction.

This peripheral movement o! the water is made up of two components, thus the water in contact with and closely adjacent to the wall of l the drum travels in the direction of the rotation of the drum while the water below the drum and that between the ends of the drum and the ends of the housing travels in the osite direction. Both these movements of the water are transversely of the housing.

The primary object of this invention is to impart to the watera movement longitudinally of the housing in addition to that peripherally thereof by providing deilectors or bailles which impart to such movement. Thereby the water of the bath is uniform throughout the housing, and ii desired the soap, bluing, starch and the like may be added to the water in the housing at the end or ends thereof instead of at the sides thereof as as is now .the practice.

Various ways of equipping 4washerslin accordance with this invention will be set forth in the following description and vin the drawings whic form a part thereof and in which: l

Figs. 1 and 2 are end views, with parts broken away, of laundry washers of the type disclosed in my copending application equipped with deilectors by which this invention is carried out;

' Fig. 3 is a view in side elevation, taken from the right of Fig. 1 or Fig. 2, with th'e housing in Figs. 9 and 10 illustrate in sectional plan and end views. respectively. still another embodiment oi' this invention.

This invention will be described as embodied in a laundry washer of the type which comprises a drum 2li, the walls of which are, in whole or in part. perforate. mounted for rotation in a hous-` ing 2|. 'I'he drum is shown in the drawings as comprising two baskets 22 mounted end to end, each basket being adapted to contain the/articles 10 to be washed. Instead of two baskets the drum may comprise a single basket or a larger number depending upon the capacity of washer desired. It will be understood that the washing of articles includes not only treatment with water containing soap or other detergent, but also further and subsequent treatments, such as with water alone to rinse the goods, followed in many instances by bluing or stai-ching treatments. For convenience. however, the term "washing is used in the speciilcation and claims in the generic sense to' include any one or more of such treatments.

The housing 2l includes bearings 23 in which the drum 20 is supported for rotation by means (not shown). The base wall 24 of the housing 2i 25 is extended to provide a reservoir 25 at one nde of the drum, as set forth in the copending application mentioned above. Mounted in the reservoir 25 are baille plates 28 which, as will be pointed out hereinbelow, serve as deectors whereby movement longitudinally of the housing is imparted to the water.

Each baille plate 26 is associated with a basket 22 and includes a main portion 2l parallel to the basket and bent at each end to form a guiding portion, the portion 28 adjacent-the end of the housing being materially longer than the other portion 22. The baille plates are spaced from the walls of the housing to denne passages 30 and ll, respectively. The portions 23 of the 4o baille plates arespaced apart to deilne a passage 32 which, as shown in Fig..5, is in alignment with the space Il betwen the baskets.

The movement oi' the water during the operation of this washer will now bedescribed with particular reference to Figs. 4 and 5. When the drinn 20 is rotated clockwise (see Figs. 4 and 5) the layer of water in contact with and closely adjacent travels peripherally with the drum, while the water below that layer travels in the 5o opposite direction. For convenience the second layer is referred toas an undertow." InFig. 4 the arrow 35 indicates the direction of rotation of v the drum and the arrows 38 indicate the directions of peripheral travel of the water. The Verg5 rows 31 on Fig. 5 indicate the travel of the water in the spaces 33 between the ends of the drum E@ and the housing fl. Since the water in these spaces is not in contact with the peripheral surface of the drum the double movement indicated by the arrows 3S in Fig. 4 is not present. The

streams of water in the spaces 38 are divided by the portions 28 of the baiiies 26 into two streams 39 and 60, indicated by arrows il and d2, respectively, and separated by the baille plates. The streams 39 are in part affected by the peripheral movement of the drum and in part continue to the portions 29 of the baiile plates by which they are deilected into the space between the drums. The streams 40 continue along the ,spaces 30 until they meet at the space 32 between the baille plates through which they ow into the space 33. In addition to the undertow movement described above, a portion oi Vthe water moved peripherally with the drum is deilected to flow along the streams d3 in' the direction indicated by the arrows M to the spaces 38.

The movement of the water designated by the arows 3S is caused by the peripheral rotation of the drum. 'The presence of the baille plates 26 causes the water to move along the spaces 38 and 3l) thus setting up a longitudinal movement of the water. The movement of the water in the streams 40 through the spaces 3l! is in response to its movement in the space 33 and of necessity draws water from the spaces 38, thus setting up the movement indicated by the arows 3l.

The movement of the water described above is that set up by the rotation of the drum in the clockwise direction indicated by the arrow 35 (Fig. 4) When the drum is rotated in the counterclockwise direction (Fig. 4) however, the movement 'of the water will be the direct reverse of the movement just described. In other words,

the water entering through space 32 will ilow outwardly through the passages t@ to the passages 3d.

The washer shown in Figs. 2 and 6 diiers from that shown in Fig-1 in that the base wall Zd' of the housing 2i is extended at each side of the drum 2li' to provide reservoirs 25'.' in each of which are mounted baiie plates 26. That the rotations of the drum 2Q willcause the water to iow peripherally and longitudinally of the housing in substantially the manner previously described is, it is believed, obvious, so that there is no need for a detailed description thereof.

Figs. 7 and B illustrate further developments of the embodiment previously described and correspond to Figs. 5 and 4, respectively. Since these developments consist in additions to the struc- "tures previously described in detail, the description of the structures will not be repeated and the same reference characters will be applied to the corresponding elements without comment. In order to guide the streams of water through the passages til, blocks titi have been mounted at the corners of the reservoir and a block 5i has been mounted at the mouth of the passage 32. A series of blades or paddles 52 are mounted on the drum 2@ between the baskets 22 to increase the speed oi travel of the water through the space 33. At the end of the space 33, opposite the block 5l, is mounted a block d@ which, as is shown in the drawings, is so formed that the stream of water is separated after flowing through the space and is deflected toward the ends of the housing 2t.

Figs. 9 and 10 illustrate the application of this invention to a washer of the well m'iown cylindrical housing type. This type oi washer, unlike the.

other types discussed hereinbefore, does not include a reservoir. A drum 6K3, rotatably mounted within the housing 6l, includes baskets 62. The articles to be washed are placed `in the baskets of the drum which has, according to the usual custom, perforate walls. The bath water is contained in the housing and enters the lower portions of the baskets through the perforations therein (not shown). Mounted upon the lower portion of the housing at one sideof the vertical plane of the axis of the drum are baiile plates 66 formed like the plates 26 with portions 8l extending longitudinally of the housing 5l and parallel to the drum 50 and bent end portions 68 and 59. The movement of the water initiated peripherally by the rotation of the drum St is affected by the baille plates 56 in the manner already described in detail with respect to the baiiie plates 26.

While certain .embodiments of the invention have been shown and described, it will be understood that the invention is not limited to such embodiments and that it also includes such other embodiments thereof as may be made Without departing from the spirit and scope of the invention set forth in the following claims.
