application filed October 6, 1919.

To aZ 007mm it may concern:

lie it known that l, HERMAN l. AxiumsnN, a citizen of the United States, and a. resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in lashing-Hachines, of which the following is a specification.

My invention relates generally to improvements in 'washingmachines but relates more particularly to improvements in power operated machines for family use.

Household washing machines are generally used in conjunction with a stationary tub which is a part of every modern laundry and which is provided with het and cold water faucets and suitable drain connections. rl`hese tubs are usually divided into a number of compartments to facilitate the operations of washing and rinsing the clothes and immersing the same in bluing water. lYhen a washing machine is used in conjunction with such tubs, the clothes are first washed in the machine and then transferred to one compartment of the stationarj7 tub for rinsing purposes heilig passed through a wringer during the transfer from the machine to the tub, which wringer is usually arwater provided and since this is usually.

heated at some distance from the machine this operation is not only laborious but dangerous as many instances of severe burning due to spilling of the water will be found.

The general object of my invention is to provide means whereby the family washing can be effected with less labor, in less time, and at less enpense.

Another object of my invention is to provide a washing machine which can be produced'at low cost and which shall in part he formed bya stationary laundry tub with its hot and cold water connections, and drains.

Again it is an obj ect of my invention to provide a washing machine which shall be adapted not only to cleanse the` clothes through power actuated mechanism, but which shall also be adapted to rinse them.

Another object of my invention is to pro- Speccation of Letters Patent.

Serial No. 328,852.

vide mechanism of the class described which can be very readily attached to and removed from an ordinary stationary laundry tub.

My invention consists generally lin the form, arrangement, construction and coperation of the parts whereby the above named objects, together with others that will appear hereinafter, are attainable, and my invention will be more readily understood by reference to the accompanying drawings which illustrate what l consider at the present time to be the preferred embodiment thereof.

In said drawings Figure 1, is a front elevation of a washing machine embodying my invention, a portion thereof being broken away and shown in section better to disclose the interior construction thereof. Y

Patented July 27. 1920.

Fig. 2, is a vertical section taken substan-v tially on the line 2-2 of lfig. 1; and

Fig. 3, is an end elevation of the washing machine.

The stationary tub 1, is formed of bottom, end` front and rear walls 2, 3, 4, and 5, respectively and is divided by a partition 6, into-a plurality of compartments 7 and 8. The number of such compartments may vary. In the present instance he back 5,

extends somewhat above the end and front walls as indicated at. 5 and through the back wall the 'ater connections pass, terminating in the hot and cold water faucets Sland 10, respectively. The tub is provided with a drain pipe 11 and a removable stopper 12.

I provide two spaced bracket members 13 and 14. which, in the present instance, are secured firmly to the rear wall of the tub as by means of bolts 15. The bracket members 13 and 14 are provided with portions 1G which straddle the top of the back wall and they are also provided with upstanding portions which terminate in bearings 17 and 18 in which the shaft 19 is rotatably mounted. The brackets also have depending portions which extend into the tub space and which terminate in sockets 20 and 21 respectively. Positioned longitudinally in the tub compartment 7 is a container for the clothes which, as-here shown, is formed of solid end walls 22 and 23, connected by a plurality of spaced slabs 24. The upper slabs are connected together and hingedli `joined as indicated at 25 so that they may l e swung open for the purpose of plaeii'ig clothes in and removing them vfrom the conattached trunnion members 2G and 27 which rest respectively in sockets 2() and 21, of the brackets v13 and 14, thus mounting the conf tainer for rocking or oscillatory movement. For the vpurpose of imparting rocking or oscillatory movement to the container I provide 'a motor 28 which is mounted, in the present instance, upon a board 29 that eX- tends between and is connected to the bracket members 13 and 14. This board 29 lnot only serves as a suitable base or mounting for the motor but also serves to rigidity and strengthen theframe partsf The motor 28 carries a pinion 30 which meshes with a gear wheel 31 keyed or otherwise secured to the shaft 19. At one end of the shaft 19 is ,affixed a crank 32 provided with a crank pin 33 and on the clothes container is fastened a' pin 34, the crank pin 33 and the pin 34 being operatively connected by the rod or bar 35. At the other end of the shaft 19, will be found a beveled gear 36 which meshes with, and whenever the shaft 19 `is in motion, drives continuously but in oppov site directions, the beveled gears 37 and 38 which are affixed to the wringer shaft 39, The details of the wringer 40 will not be described except to say that it is provided with the wringer rolls 41 -and 42 which are connected by means of gearing 43 sog-that when the shaft 39 rotates motion will be imparted to the wringer rolls 41v andf42. For the purpose of operatively connecting the gears 37 and 38 to the shaft 39 the clutch member 44 -is provided, which is feathered to the shaft, and which is of such length that it can be positioned in a central or neutral position thereby permitting the gears 37 and 38 to rotate idly, or it can be positioned 'so that the jaw portions thereof connect either of the gear members 37 or 38 to the shaft thus providing for operation the wringer in the direction desired. For the purpose of shifting the clutch member 44 a rod 45 is provided which 'is shiftable longitudinally of the wringer and which at one end has a depending arm 4G that straddles pins 47 on the clutch member 44. The wringer, in the present instance, is very rigidly secured to the bracket member A14. by a bracket 48, the wringer being thereby supported a suflicient distance above the top of the tub to permit easy access to the tub compartments. The electrical connections to the motor havenot been shown but these it will be understood may be of approved or desired construction and will preferably include an electric switch within convenient "reach of the .operator.

ln all washing machines which depend for their action upon relative movement of the water and clothes for the cleansing action it is desirable to make this relative movement as rapid and vigorous as .is possible without subjecting the clothes to pulling or tearing strains. With the construction here shown wherein the clothes are merely placed within the container there is, of course, no danger of tearing even the most delicate articles.` As the container rocks or oseillates back and forth as indcated by the dotted lines in Fig. 2, the water in the tub is caused to surge through the clothesand thereby cleanse them. In order to-increasev and make more rapid and Vig` orous the flow of water through the garments, I provide means whereby the water is forced or thrown into the top of the tub so that it must necessarily flow downwardly and throughthe container and clothes. This mechanism comprises a longitudinally disposed plate-vlike member 49 which is attached to the bottom of the clothes container by means of hinges 50. On one side of the member 49 is provided a stop member 51 which prevents the member 49 from swinging beyond a vertical position in that direction.A Thus as the container swings in the direction of the arrow '52, the member 49 swings upwardly 'to the position shown in dotted lines in Fig. 2 so that it does not seriously disturb the water and suds when moving in that direction. However, when the container swings in the direction of the arrow 53, the member 49 is immediately forcibly rcturnedto the vertical position shown by full lines in Fig. 2, and it` therefore, pushes or sweepsv a considerable V0llune of water forwardly and upwardly, throwing it to the upper part of the container and thus more certainly insuring complete circulatory movement of all of the water with its consequent morethorough cleansing action.

. lV hen the machine has operated a length of time sufficient to cleanse the clothes in the container, if desired, they may be rinsed. in .the same compartment utilizing the power mechanism for this purpose. This becomes 'practically possible because the stationary tub is provided with a drain 11 which permits the rapid draining of the suds with no more labor than is required to remove the stopper and after the suds have been drained the water in the faucets may be turned on while the oscillatory movement of the container tumbles the clothes. This'tumbling motion of the clothes and'the fresh clean. water soon operate thoroughly to rinse them and so soon as this is' accomplished the ma` chine may be stopped, the clothes removed from the container, and passed through the wringer into the 'next compartment of the tub. It will be'u'nderstood that the Wringer is power operated and'since at times it may provide the connecting rod 35 with a hinged is done rotation of shaft 19 causes idle rotation of crank 32. The member 35 is held in closed position by means of a spring latch 35".

Of course, if desired, the clothes may be removed from the container before they are rinsed and placed in rinsing water in the next compartment where they may be rinsed by hand in the 'usual manner. If this be done the washing of another batch of clothes may be carried 011 while the rinsing of the previous batch is attended to, but thesmall amount of time required to-rinse the clothes in the manner. before described will probably make this the preferable procedure.

The mechanism herein shown is of such construction that it can be readily attached to any standard stationary tub, and is of such simple and inexpensive construction that it is within the means of those having only a very moderate income, and since the character of the water container limits the life of the article, the machine is of very durable character because of the fact that a stationary tub, composed as it is of slate or cement, is installed in such manner that it remains in operative condition over a long period of years. In the washing operation there is no need of carrying water either for theV purpose of replenishing the machine from time to time as required for the washing of a number of batches of clothes, nor is it necessary to carry water drained from the machine since in one instance the water flows in through the water faucets and in the other Hows out through the drain all of which are a part of the standard stationary tub. The present machine, therefore, is not only much less expensive than those heretofore provided, and of greater durability, but it also results in a very marked reduction in labor and time .A required to cleanse a given number of articles. Rinsing of the clothes is quite as important as washing them and when this is carried on by hand there is likelihood of this operation being slighted.

Inasmuch as this disclosure will readily suggest to others skilled in the art to which this appertains, modified structures whereby the substantial objects and purposes of my invention may be attained, I do not wish to be limited to the specific construction herein shown and described, except only as may be: necessary by limitation in the hereunto appended claims.

I claim:

l. A washing machine embodying therein a water container, a clothes container mounted for oscillatory movement therein, a plate arranged on the underside of the clothes container and longitudinally thereof, means hingedly securing the plate to the clothes container whereby said plate can swing toward the' clothes container when the clothes container moves in one direction, and a stop arranged on the clothes container and positioned to limit swinging movement of the plate when the clothes containerl moves in the opposite direction.

2. In a washing machine for attachment to a stationary tub, bracket means formed to embrace the back of the tub and being formed to be rigidly attachedthereto, said 4bracket means having forwardly and downwardly extending arms, said arms being formed ne'ar the outer ends with. bearings adapted to receive the trunnions of a 'clothes agitating element, said bracket means also having upwardly extending arms terminating in bearings adapted to receive a shaft of -mechanism for use irq'T operating lthe clothes agitating element adapted to be supported by said downwardly and forwardly extending arms.

In testimony whereof Ihave hereunto set my hand this 29th day of September, 1919.
