WASHING MACHINE;

Application filed October 31 To all whom it may concern:

Be it known that we, PETER F. SCHNEI- o one, RanroND J- UCHNEIDER, and WILLIAM I F. BLAKE, citizens of the United States, residing at Detroit, county of Wayne, State of Michigan, have lnvented a, certain new and useful Improvement in lVashing Machines, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings which form a part of this specification.

This invention relates to washing machines, and the object thereof is to provide an improved mechanism including what are termed vacuum cups reciprocable in a tub to force wash water through the clothing, and relates particularly to the arrangement of a plurality of cups substantially, equidistantly positioned about the center of the tub whereby the clothing is practically all subjected to the washing effect of the 'cups without necessity of revolving the tub or of altering the position of the cups about the center as has heretofore been done. i

In previous known construction employing cups reciprocable to produce movement of the wash water through the clothing :the cups have been turned about a center whereby all of the clothing beingwashed' is subjected to equal washing action by the cups 7 and such construction either in the turning of the cups or of the tub results in a winding of the clothes about each other. This undesired result is obviated in the present construction by use of a greater number of cups whereby the washing effect is. substantially equally distributed through "the 'entire quantity of clothing, the only movement, of the cups being a reciprocable movement.

A further feature of the inventionis'involved in the construction whereby the cups are arranged in pairs on oppositesidesof the tub and are reciprocated in alternate relation, resulting in a more rapidlyfloper ating machine than with previous types. An additional object of the invention viscto provide a false bottom preferably supported centrally of the tub whereby the'downward operation of the cups on one side tends to depress that side and to raise the other side thereby fiufling the clothing in the water.-

r A further object is to provide a false bottom having perforations; and adapted to be raised from the bottom' to near the top whereby the clothes may drain prior to being passed through the wringer and obviat- Iing t-he necessity ofthe operator picking the clothes out of the'heatecl water. These objects andthe other minor Objects of the invention and'the several novel featuresof construction thereof are hereinafter more fully described and claimed and shown in the accompanying drawingsin which Fig. 1 is a vertical section showing our improved washing machine. 3

Fig. 2 is a plan View thereof.

Fig; 3 is a side'elevationof the machine showing the operating mechanism.

Fig. 4 is anelevation of mechanism employed in reciprocating the cups. I

Fig. 5 is a detail illustrating the nechanism employed in operating the wringer.

Fig. 6 is an elevation in detail showing the, clutch mechanism for independently applyingpthe power at willto the wringer or to the washer.

In the embodiment of the inventi'on herein shown, the tub is indicated at, 1 which is preferably of metal' and withinythe tub are two pairs of vacuum cups2 and 3'positioned on opposite sides of the center line, the pairs;

of cups Zbeing supported 'ona yoked and the' pairs ofcups 3 being-supported on a yoke, 5. Preferably a cup2 is spaced from its companion a distance approximately equal to that of its spacing from a cup 3 so that the fourcups are substantially equirespectively on opposite sides of the-tub.-

Theshafts or rods? and 7 are preferably reciprocable in alternate relation and, any approved mechanism may be employed to so reciprocate the rods, the mechanism shown being a horizontal shaft Shaving a worm gear 9 thereon operated by, means of' a worm 10gonthe shaft of the motorll, the

particular arrangement of the said: construction being hereinafter more fully de-' scribed. On opposite ends of the shaft arev provided cams 12 and 13 similar in form but oppositely disposed. On each rod 7 and 7 is mounted a pin or roller 14 in each case riding on the periphery of the cam. These rods 7 and 7 extend into bearing members 15 and, 16' respectively so that the shaft is guided by the lower bearings and the bearings provided therefor within the tub and the cam rollers 14 are positioned between the bearings. A coiled spring 17 is provided for each rod which is a tension spring in the construction shown tending to draw the shafts and cups thereon downward in the position shown at the left of Fig. 1. By

3 rotation of the shaft 8 and the cams 12 and 13 thereon the shafts 7 and 7 are alternately raised as is shown at the right hand side of Fig. 1 and, when so raised the springs 17 are placed under tension causing the roller to continuously ride in contact with the cam. By this construction the cups are raised from engagement with the clothing by the cams and are forced into contact with the clothingby the springs.

By this arrangement no detrimental effect neath one or the other of the cups.

can result in operation when a greater quantity of clothing is accidentally piled be- If the cam members were of a construction producing a positive movement in both directions of the shaft 7 or '7 an increased quantity of clothing would tend to cause a breakage or a pounding having a detrimental effect on the mechanism. By providing a movement of the cups that is yieldable in a downward direction such pounding or possible breakage is avoided.

The clothing is washed in the well known manner by forcing these cups which are termed Vacuum cups onto the clothing immersed in the heated water and then down' ward movement causes water to be forced through the clothing and the succeeding upward movement tends to draw soapy wash water upward through the clothing and this continued movement backward andforward of the water through the clothing F results in cleansing-thereof. By arranging in the tub having a series ofperforations 19 of any approved form therein. Preferably this bottom has a peripheral upwardly extending flange 20 thereon shown by dotted lines in Fig. 1 whichlies close to the inner wall of the tub and is short in length to prevent the clothing from working off from the said bottom into the interstice between the tub and the said bottom. This false bottom as shown in Figs. 1 and 2 is pivotally supported on a shaft 21 and when clothes are placed in the tub the alternate movement of the cups 2 and 3, rocks the false bottom on its pivot which fluffs the clothes and prevents them from remaining in a compact mass beneath either of the pairs of cups. The pairs of cups are detachably mounted on the ends of the shafts 7 and 7 By removal of the cups from theends of these shafts, the false bottom may be lifted by the two handles 22 until clear of the water, whereupon the clothes supported on the said false bottom drain through the apertures therein and thus allow the operator to handle the clothes without immersing his hands in the hot-water contained 111 the tub. To support the false bottom above the water in the tub, the rods 22 are provided with joints 27 at about the center thereof. When the bottom has been raised within the tub the handles or rods 22 are turned over the upper edge of the tub by means of the joints 27 and thereby the false bottom is. supported in the raised position. As will be noted from the drawings, handles 23 and 24 are provided which operate companion clutches the handle 23 operating a clutch 25 which connects or disconnects the motor with the washing machine mechanism and the handle 24 operating a clutch 26 which connects or disconnects the motor with the wringer mechanism. Thus by use of these handles or levers, the washing machine or wringer may be operated at will OI Wli3l1-' held from operation.

From the foregoing, it becomes evident that the device is very efficient in operation,

is easily handled and accomplishes the objects desired.

Having thus briefly described our invention, its utility and mode of operation, what we claim and desire to secure by Letters Patent of the United States is" 1. In a washing machine, a receptacle substantially cylindrical in form, a pair of rods one on each side of the tub extending upward through the bottom thereof, a vacuum cup supported on each rod within the tub, guideways in the tub for the said rods, and power operated means beneath the tub for reciprocatingthe rods in alternate relation.
