An object of my invention is to'provide a washing machine wherein a cleansin fluid is forcefull passed through ing washed.7

Another object of my invention 1s to rovide a device of the class described in w ich articles ma be washed and rinsed without removing 'the articles'therefrom.

Another object of m invention is to pro vide a simplel and e cient device for the pur oses stated.' i lT ese and other objectsare attained \by 4 the means described herein and disclosed in the accompanying drawings, in which:

Fig. lis a side elevation of a device embodylng my invention, parts being broken F1g. 2 is a sectional view on line 2-2 of Fig. 1.A Y y Fig. 3 is a vertical section of a modified form of device embodyin my invention.

Fig. 4is a sectional .view taken on line 4-4 of Fig. 3.

The tub 10 is provided with suitable legs or supports 11 and 110. A suitable mounting 12 is provided for a mot0r.13 for driving shaft 14, carrying worm 15, operative on the worm wheel 16, and carrying crank 17. A connecting rod 18 exten s pivotally connected with a crank 19 carried by the shaft 20 extendingtransversely of the tub atnthe top thereof. Fromthe foregoing, it will beevident that an oscillating motion is im arted to the shaft 20. At op o site endsl o the shaft 20, there is provi ed an arm, said arms 21 and 22 revoluly supporting a shaft 23 disposed within the tub 10. cylinder. 24 is iixed on the shaft 23 and is provided with a suitable door 25 that may be-secured in a closed' posi-V tion upon the c linder, and may .also be o cned for permitting access to the interior ci the cylinder for depositing and removing articles. The ends of the cylinder'may be provided with reinforcing members 24a through which the shaft 24 extends.

Attention is called to -the fact. that'the shape of the 'tub is such as to conform substantially to the arc through lwhich' the cylthe artic es be- 'between' the cylinder and the tub bottom upwardly from the crank 17 and has its upper end ing clothes to Y Fig. 1, it will be observed that Vwhen the inder is oscillated or swung. Except for the lateral extensions 26 and 27 at the sides of the tub, arelatively close fit is provided 28 and side walls 29 and 30. The clearance between said arts of the device is ap roximately one ourthv inch. The outer en s of the shaft 23 carry spur gears 31 and 32 that mesh with arcuate racks 33 and 34 disposed in the recees 35 and 36 provided in the lateral extensions 26 and 27 formed at 'the sides of the tub. The racks 33 and 34 may be mounted upon the sides of the tub as shown at 34* in Fig. 4, or they may be boltedto the upwardly pro- `jecting extensions 37 and 38 of the legs 11 and 110. Reinforcin bars 39 and 40 may follow the contour o the lateral extensions 26 and 27 and serve as supports for the tub.

The reinforcing bars maybe bolted to the extensions 37 and 38 as indicated b 60.

The cylinder 24 is provided wit a plurality of openings or perforations 41 through whic water ma enter the cylinder. The inner surface of the cylinder is provided with ribs 42 that extend toward the shaft 23 and serve as deflectors for directing fluid entering the perforations, onto and through a mass of wash within the c linder. The operation of my device is as ollows: An oscillating or pendular motion is imarted to the e linder or basket 24 containwashed.l By reference to basket is swung in a clock-wise direction, the

basket itself will revolve with the shaft 23 Y in a clock-wise direction because of the engagement of the-spur gears upon the arcuate racks. This movement of the c linder serves to amass the water at the le hand en d of the tub although some of the water will be finding its way through the cylinder andbetween the cyhnder, the bottom and sides of the tub. The greater portion of water will, lbecause it is amassed at the left hand end of the tub be forced through the cylinder, as the cylinder approaches its left hand limit of travel. Thls forcing-of the water through the cylinder and the clothes serves to place the water under-great presllll sure, the pressure being suicient to carry the dirt out of the intersti'ces of the fabric of which the clothes are made. Upon'the change in .direction of the movement of the fabric the same action is attained at the right hand end of the tub.

A suitable drain cock is provided in the bottom of the tub so that the water may be drained from vthe tub without removing the wash from the cylinder. In this way it is possible to first soak the clothes incold water, whereupon this water may be drained from the tub. Hot soapy water may then be admitted to the tub. After the operator has concluded with the soapy hot water., same may bedrained from thetuband rinse water run into the tub. The cylinder would be reciprocated in each of the different tubs of water enumerated, so that a thorough soaking, a thorough washing, and a thorough rinsin of the clothes -is attained in the order name This is a procedure that is of particular value in household washing machines.

Attention is called to the fact that the o posite ends of the tub are developed into camber like `structures into which the cylinder is swung.y The mass of water moves before the cylinder and is impounded inthe chambers and the movement ofthe cylinder into such water filled chambers forces the water through the cylinder and the clothes therein. The arcuate cavity in the tub, and through which `the cylinder is swung is so constructed that but a little water may ow past the cylinder. The oscillating and rotating movement of the cylinder in a com- A, mon direction serves to check the flow of water past the cylinder. It will be readily evident that the shaft 23 need not extend through the c linder, and that stub shafts v23a at the en s of the cylinder, see Fig. 4 will perform the function of shaft 23. The appended claims are drawn withthe intention that such stub shafts shall fall within said claims. It will also be readily evident that the tub 10a, see Fig. 4,. may be elongated and the cylinder or basket be reciprocated rather than oscillated. The claims ap pended hereto are intended to cover such structures, although the oscillating type machine is referable for various reasons.

What claim is: A

1. In a wash machine the combination of a tub having an arcuate bottom and substantially vertical side walls, the side walls being provided with lateral extensions for i provlding recesses at the sides of the tub, a

perforated cylinder within the tub, having` end walls and arranged for backward and forward movement, the cylinder walls being closely adjacent, but spaced suicientl from the lower ends of the walls-of the tu to permit movement of the cylinder-within the tub, whereby movement of the cylinder within the tub will serve to move the greater mass of fluid ahead of the cylinder and to minimize the How of uid between the cylinder and the tub soA that the major portion of the uid is im ounded on a given side' of the cylinder and) forced through the perforations in the cylinder upon movement of the cylinder into the impounded fluid, and means within the recesses to move the cylinder backward and forwardpwithin the tub. 2. In a wash machine the combination of a tub havin a substantially arcuate cavity, a shaft at t e top ofthe tub and extending transversely thereof,- a'n arm adjacent each end of the shaft and extending downwardly .into the tub, means for oscillating the shaft,

a second shaft disposed within the ltub and A revolubly supported by the lower ends of the arms, a perforated'A cylinder ixedly mounted on the second shaft, adapted to be oscillated in an arc conforming substantially to -the arcuate cavity in the tub, the cylinder being closely adjacent, but spaced sulliciently from the tub to permit relative movement of the cylinder and tub, the space between the cylinderand tub being insuicient to permit an appreciable `flow of fluid between the cylinder and tub, whereby movement of the cylinder causes the fluid in the tub to be moved before the cylinder and impounded 1n the ends of the cavity, sov that further -oscillation of the cylinder causes the imounded fluid to be forced through the perorated cylinder.

3. In a wash machine the combination of i .a tub having a substantially arcuate cavity,

a yshaft at the top of the tub and extending transversely thereof, an arm adacent each end of the shaft and extending dlownwardly into the tub, means for oscillating the shaft, a second shaft disposed within the tub and revolubly supported by the lower ends of the arms, a. perforated cylinder xedly mounted on the second shaft, adapted to be oscillated in an arc conforming substantially to the arcuate cavity in the tub, whereby movement of the cylinder causes the fluid in the tub to be moved before the cylinder and impounded in the ends of the cavit wherethe impounded fluid to be forced through the perforate cylinder, a gear \fixedly mountedon the second shaft, and an arcuate rack carriedby the tub and engaging the gear, the

rack being positioned intermediate the `shafts whereby the cylinder is simultane` ously rotated and oscillated in the same general direction.

4. -In a washing machine the combination of a tub having an arcuate bottom and substantialy vertical side walls, the side walls,

being provided with lateral extensions for providing recesses at the sides of the tub, a

perforated rotatable cylinder within the tub, bagging end walls and arranged for back- Wa.

d and forward movement, the cylinder walls being closely adjacent but spaced suiii. ciently from the lower ends of the walls of the tub tol permit movement of the cylinder within the tub, whereby movement othe cylinder within the tub wil serve to move the greater mass of fluid ahead of the cylinder and to minimize the ilow of 'luid between the cylinder and the tub so that `the major-Lv portion of the fluid is impounded on a- 'ven side of the cylinder and forced throng the perforations inthe cylinder upon movement I of the cylinder into the `impounded fluid, means wlthin the recesses to move the cylinder backward and forward within the tub, and means for positively rotating the cylinder.

5. In a wash machine the combination of a. tub havin end and side walls, a perforated s cylinder within the tub, the walls ofv the I cylinder being closely adjacent, but spaced sufliciently from the side walls of the .tub to permit movement of the cylinder relative tothe tub, the 'space between the walls of the tub and cylmder being insuicient to permit an appreciable How of liuid between the said walls, whereby movement oi the cylinder between the `limits of the tub serves lto move the major portion of the fluid content of the tub towards the ends of the tub with the cylinder and to thereby force the fluid so confined at the ends of the tub, through the perforations and the articles in the cylinder, and means 4for oscillating and rotatin` the cylinder in a clockwise i direction and for alternately oscillatin and rotating the cylinder in counter-cloc ise direction, within the tub. f

In testimony whereof, I have hereunto subscribed my name this 24th day of September, 1924.

FRANK SNYDER.
