WASHING-MACHINE.

-T o all 'whom it may concern:

AMy invention. relates. to washing machinesl of that type in which a rotary drum is prov1ded,lsa1d drum rotating withinan outer easing, the drum being perforated so that the water contained within the. casing and within the drum may have a thorough contact with the clothes, so that air may be sucked into the water, the object of the invention being to provide a drum of such construction that. considerable air will be sucked 'into the water and the clothes washed quickly.

For a full understanding of the' invention and the merits thereof and also to acquire a knowledge of the. details of construction,

. reference is to be had lo the following description and accompanying drawings7 in which:

Figure 1 is a front. elevation of the' machine partly in section; Fig. 2 is a transverse section on the line --y of Fig. 1.

Corresponding and like 'parts are. referred to in the following description. and indicated in all the 4views of the drawings by the same reference. characters.

Referring to these figures, Q designates the body of the machine mounted on the legs 3, and 1 designates a motor whereby the machineis to be. operated.

4 designates aframe'attached to t-he end .ofthe machine and supporting the end of the main driving shaft 'to which power is communicated by means of the belt wheel f 5 driven by the motor 1,and from which power is communicated to the .drum in any suitable manner. A

6 designates a. Wringer driving shaft and 7 designates bevel gears 4trans1nitting-f power from the shaft 6- to thewringer rolls. The

lower end of the shaft 6 is provided with the bevel gear S which meshes Witha bevel gear 82l on the main driving shaft.

A designates the drum and 1% designates the corrugated sides of the drum. This drum has the form of a rentrant poiygon,

and it will be seen that broadly speaking the barrel ot the drum is corrugated or pro Specification of Letters Patent.

vided with alternate inwardly and outwardly projecting ribshaving angular sides.

T he sides of the drum are perforated, as at 1t, and 'the interior face of the .drum is provided with longitudinally extending, inwardly projecting riiles 15. 'The 'apeir.\of 'l each of the outwardly projecting ribs oran-,v gles of'thedrum is provided with a deflect-' ing plater 13. This defiecting plate. extends' longitudinally of the drum from one end po the other and projects laterallyoneach sidel partly over thc-'adjacent'face of the drum. 7 `These detiecting` lates'in conjunction with.

the adjacent incined faces of 'the drum,

form pockets wherein air and water is con 7^() tained as the drum rotates, and act there fore as thedrum is rotated to carry airinto theA water and agitate itmorethoroughly than 1s ossible with a drur'n not provided with der ectin'g plates.4 It will also be seen 7 5 that the interior corrugated face of the drum will act very positively uponlthe clothes to cleanse them, and that the rimes* will act to carry the clothesup the'side of the drum and the-n allow them to drop- 80. .downward into the water in the lower Vportion of the drum. The endso the drum-are, provided with lthe spiders .12 having 'thereon'4 the outwardly projecting'shafts upon which'.

the drum is mounted` these shafts revolving .8 5

in the supporting bearing 11 attached to the ends of the body 2. One. portion of the drum is forme-'l of the removable section 17. which forms a door whereby clothes may be put into or taken out of the drum. This 9.@

door is hinged at one edge to the body of the drum, While the other margin4 of the door opening 'is provided-With the buttons 2O orother latches, whereby the door may be held closed. The main body of the machine is covered by the top plate 19 having the downwardly projecting tianges {itt-ing inside the sides .of the main body ortank,`. and the lower semi-cylindrical portion of the exterior casing 2 or body .is provided with av .1 '00 drainage opening 21 whereby the water may be emptied from the machine. y The particular feature of my invention resides in the peculiar form of the drum with its sides having rentrant angles, the '105 apices of the corrnofations being provided with the deiecting plate-s 13. It will be seen that as the drum rotates within the main body of the structure the water and air will be carried up by thepoclzets formed by U0 these deeeting lplatessl, and that the iva-l terv will therefore dz. fin dovvn through the perforations 1G in sides of tlie drinn afterjtlie druinlias passed above the water :in the tank. The defleetiiig plates project-- ing partly over tlieinivardly inclined sides 'of the drum, will also cause-these sides be- 4tween the ribs lto carry -up yand detain, a

large amountof water and air as they druin rotatesv and to suol; air into the Water, thus .it-he clothes Withintlie druni are thoroughly aerated. The pressure of the air vvill loree sltrueted as above described,4 is adapted to be actuated by any suitable 'lineeliaiiisnn and tlie water into4 and tlirougli'tlie fabric and 'the clothes will be thoroughly and quickly eleaned.
