WASHNG :MACHINE .application filed July 14,

To @ZZ whom t may anc-(1ra:

it known that l, lll/linnn n subject, residing al Loitm n l London, lgland have i and useful im arovements in v g "lachines (for which l. have filed application in England, inlay Q7, i920, Pat

l i4i,505), oi" which the following is specification.

This invention 'relates to washing machines having` circular 'otary cages adapted to be rotated alternately in opposite directions. iuch machines iave already been provided with internal beaters in the forni of longitudinal ribs or projections of vvarious shapes adapted to operate upon the materials being washed during rotation.

The present invention primarily consists in a w shing machine having a cage whereof the eircumferential wall is shaped'to form one or more longitudinal combined internal beaters and external perforated troughs, the latter being adapted to raise to a predetermined height a charge of water externally to the cylinder and cause it to be discharged through its perforations on to the materials being washed within the cylinder. lt further consists in a precise form and arrangement of such combined beater and water trough which l have found to possess considerable advantages over and above those functions which are solely attributable to the mere combination.

The combined beater and trough. are preferably formed by shaping a single plate of metal forming part of the wall of the cage so that outwardly it forms two troughs and inwardly it forms two beaters.

The preferred form of the invention is illustrated in the accompanying drawing in which Fig. l illustrates an elevational view and Fig. 2 a sectional view.

Referring now to the drawing, the combined troughs and beaters a, are formed in opposed pairs, each pair being preferably formed from a single metal plate Z', b2, Z3 united at its edges to the cylindrical parts 7L- of the rotating cage. The remote walls c of each pair of troughs are preferably set in planes passing through the axis of the cylinder, but t-he near walls Z form an angle therewith and approach each other so as to form in conjunction with the intervening part e of the cage wall which lies on the normal cylindrical circumference7 an internal pocket within the cage which is adapted Air Janson, .a isoad,

ieeif serial no. 484,721.

to receive the charge 'of material to be' washed and cause itl to be raised, as the cage rotates, to a. point whence it falls on to the near beater l@of the following pair. it this 1Wint, kas the beater is moving in a sense opinsite to the direction of fall, the charge is beaten and rolled over into the succeeding pocket, when the process is repeated.

rlhe walls/Z and intervening part e of each system are freely perforated, the perforations being partly indicated in Fig. l by centrings only; and extensions g of the cy-v lindrical portions extend partly over 'the troughs Z from the walls c in each case to ensure that a substantial charge of water is raised by the troughs above the level of the water in the machine. This charge of water, as the troughs are' raised, falls through the perforations in the walls Z on to the material in the cage, a certain quantity being directed on to the said material as it falls from the rising pocket f on to the lower beaters, and this combines with the operation described above to produce a very el'licient cleansing of the material. lt will be understood that of each pair of troughs, one functions as the cage rotates in a clockwise sense and the other as the cage rotates in a counter-cloclwise sense. ln the drawing cvrepresents a central portion, Z parts of an end plate, and 0 ahinged door.

rlhe number of troughs and pockets and precise configuration thereof may be varied according to the size and speed of the machine; but it is desirable that as the nia-- terial falls from a pocket as the latter becomes inverted, the inclined wall from which it slides should be set at such an angle as to throw the material on to the near upturned beater of the following pair, when the rotation of the machine delivers it at once into the corresponding pocket. The near walls of a pair of troughs and intervening cylindrical portion of the shell may be shaped to form a continuous curve if desired.

ln the form shown, I have illustrated three pairs of troughs and beaters as I find that this produces the most satisfactory results with the usual size and speed of running of the machine.

l claim:-

1. In a washing machine, a cage adapted for alternating rotary movement, the wall of said cage being made up in part of independent sections, each formed to provide two hollow troughslike beaters opening exteriorly of the trough and having a short straight wall substantially `radial of the cage and a long straight wall at an angle to the shortwall, the long wall being perforated thruout its area and projected at such an angle to the radial line or' the cage that `its continuation would intersect the short wall of the immediately adjacent beater of the next section, whereby the material lifted between the beaters of one section will in delivery from said section by gravity during movement of the cage be directed by the long wall of one beater of such section onto the point formed by the long and short walls of the following beater of the adjacent section. o

Q. In` a washing machine, a cylindrical cage adapted for alternating rotary movement, the wall of the cage being made up in part of three independent sections, each formed to provide two hollow trough-like beaters having a short wall substantially radial of the cage and a long wall at an angle to the short wall, the beaters of each section having the long walls adjacent each other with thatJ portion of the section intermediate the relatively outer ends of the said long walls disposed in the plane of the wall of the cage, the angle of each long wall being at such an angle to the radial line of the cage that if continued it wonld intersect the short wall of the following beater inwardly .of the inner end thereof, the long walls and intermediate curved portion or' each section forming a pocket having divergent straight walls7 one of which according to the direction of rotation acts as a guide for the clothes falling from such pocket to direct the clothes onto the point formed by the short wall and long wall of the following beater section in the direction of rotation.

ln testimony whereof I affix my signature.
