H/s ATTORNEY Patented July 18, 1933 UNITED STATES ANTON E. HANSON, OF CHICAGO, ILLINOIS WASHING MACHINE Application filed April 9,

This invention relates in general to machines for washing clothes, but more in particular it has reference to a mechanically operated machine which provides a washing 5 machine for washing clothes in general, and

even the finest of fabrics, such as delicate lace and silk cloth, without the least danger of the goods being torn or injured, or of coming in contact with any moving mechanlsm.

An important object of the invention contemplates a washing machine which provides not only a machine for washing and cleaning clothes, but one wherein dishes may be washed and cleaned.

Another important object of the invention contemplates the provision of a washing machine wherein the washing liquid is being forced back and forth, alternately, in an upward and downward motion through the clothes, and slightly changing the position of the clothes during each alternation, during the process of washing, so as to thoroughly wash and clean every article which may be in the process of being washed.

Another important object of the invention contemplates the provision of a washing machine wherein provision is being made whereby the washing fluid is being lifted, or pumped up, as it were, and spilled over the articles in the machine and, simultaneously draw the fluid down and away from the articlcs in an upward movement of an oscillating plunger and, on a reverse movement of such plunger, force such downwardly drawn fluid back in an opposite direction and against the articles. In such manner of washing, and of the movement of the Washing fluid, the articles, such as they may be, are being kept continually agitated to the extent that every particle of such articles are being continuously subjected to the swirling back and forth motion of the washing fluid, resulting in a thorough washing and cleaning of the articles in, comparatively, a very small space of time.

The invention further contemplates the provision of a washing machine having a 0 pair of oppositely oscillating paddles, or

pumping devices, which work, in the manner 1931. Serial No. 528,849.

of apump,in an oscillatorymotion in opposite extended curved spaces being enclosed by inner and outer curved walls and end plates comprising inner and outer Walls of the washing machine. The spaces being spaced apart by a central partition disposed longitudinally of the machine between the inner and outer curved walls and extending to the end plates along the bottom of the machine. The spaces, however, being left open at their upper extremity, and through such opening the washing fluid is being spilled, alternately, first through one and then through the other, over distributer plates and over the articles being contained within the inner curved 65 walls. The inner walls having a multiple series of spaced perforations arranged in parallel rows throughout their length and spaced a distance out from the central partition. Through such perforations the washing fluid is being pumped back and forth, during the process of washing, by means of said pumping devices.

The invention further contemplates the provision of a pair of oscillating pumping paddles, or pumping devices, being so arranged as to work simultaneously but in opposite directions of each other so as to pump the washing fluid alternately up and down through the articles being washed to the extent that such articles are being 'kept continually agitated back and forth in every direction so that every particle of such articles is being thoroughly washed through the swirling action of the washing fluid.

The invention further contemplates the provision of mechanism for simultaneously operating a pair of oppositely arranged pumping paddles, or pumping devices, in an oscillatory motion in contra-direction of each other. It further contemplates the provision of, comparatively, a very small fractional horse-power motor to operate a washing machine of the above construction and of a size suitable for household use. In such household machines a one-sixth t) horsepower motor will be amply sufficient. Therefore, providing quite a saving in the cost of operating such machines in homes.

The invention further contemplates the provision of a collapsible stand for supporting a washing machine, of my construction, to any suitable and convenient height above the floor and over a sink whereby the same may be drained. It further provides a stand which may be folded together and the whole apparatus be stored in, comparatively, a very small ont-of-the-way place, as, for instance, in a small closet, or under a table. And, even, the machine may be of such size that it, and the stand therefor, may be stored under a bed.

The invention further contemplates the provision of a washing machine having inner removable parts which may be removed from time to time for cleaning the interior of the machine and, for making repairs, if necessary.

The invention further contemplates a washing machine of the above description which is comparatively simple of construction and having a neat pleasing outward appearance, and which may be manufactured at, comparatively, a very small cost.

The invention further contemplates the provision of a cover for the machine which provides a hollow drainboard whereupon washed goods, as may be taken from the wash. may be placed and the surplus water and moisture removed from them by means of suction or vacuum being produced within the cover.

These and other objects of my invention will be better understood by referring to the several illustrations in the accompanying drawings, and will be more fully described in the following specification, and more particularly pointed out in the appended claims.

Illustrated in the accompanying drawings;

Figure 8 is a detail of the mechanism, comprising a pumping plunger. for circulating the washing fluid in the machine; and

Figure 9 is a detail of the mechanism, comprising a pumping plunger, as being employed in the modified form of my invention, for circulating the washing fluid in the machine.

Similar characters refer to similar parts throughout the several views.

In the main, my invention comprises, substantially, a pumping device wherein cloth abric, and even dishes, may be thoroughly cleaned by pumping the washing fluid, which may be contained within the machine, over the goods and forcing it upwardly and downwardly through the goods to the extent that the goods (cloth, etc.) as having been insert-ed through top opening 63, and deposited in the basket 20, are being kept continually agitated and turned to expose every particle of the goods, such as cloth fabric, to the circulating action of the fluid.

To illustrate my invention I have shown in the drawings a washing machine comprising an outer frame or casing 10, enclosing inner and outer walls 11 and 12 respectively. The inner and outer walls being spaced apart, preferably in the manner indicated in Figures 3, 4-. 5. and 6, to provide space in which to operate a pumping plunger 13, or, 14.

In order to support the washing machine at various heights, or to store it away in an out-of-the-way place, a collapsible stand 15, is provided and attached to the machine preferably in the manner indicated in Figures 2, 3, and A locking device 16, being provided whereby the stand 15, may be securel locked from collapsing from any position to which it may be arranged.

In the present con:--:tructi(m of the machine, sides 17 and '18, are curved to form a pair of curved walls concentric with each other on either side of the longitudinal center of the machine. \Valls 17, being preferably formed into two identical halves having flanges 15) formed therein. Upon these flanges is supported a coarse mesh wire frame or basket- 20. The halves being joined together, as at 19, by welding. Also, the upper and lower longitudinal edges of 17, are flanged over as at 21 and 22. The. upper and lower longitudinal edges of 18, being flanged in the manner indicated at 23 and 2 1. Flanges 24, being joined together by welding, as is indicated at 25. Flanges 24, being so formed as to provide a. groove 26, and a longitudinally extending dividing wall or partition 27, centrally between opposite curved spaces 28.

Referring to Figures 3, 4, and 6, it will be seen that walls 17, have a series of inclined deflectors 29, formed therein by shearing out a portion of the material leaving openings 30, through which the washing fluid is being pumped during the operation of said plungers. In as much as the deflectors are inclined in the same general direction, the fluid, on being pumped, takes a course also in the same general direction whereby, during the process of washing, the goods, such as cloth, are being kept constantly moving around from one position to that of another so that every particle of the goods is being thoroughly washed.

Walls 17, are provided with end plates or walls 31, as seen in Figures 3, 4, and 5, or, with end plates or walls 32, as seen in Figure 6. The end plates being flanged over to form ofl'set portions 33, which are adapted to extend to end plates or walls 34 and 34, 35 and 35', and there fastened as by means of screws 36, so that inner walls 11, may be removed at any time for cleaning. Walls 31, 32, 34, 34, 35 and 35 being, preferably, welded to their respective walls 17 and 18. The lower edge of plates 34, 34', 35 and 35' being bent out, as at 37, and flanged down, as at 38, to form offset portions and means for fastening walls 11 and 12 to the outer frame or casing 10. The walls being preferably fastened together by means of rivets 39.

As will be seen in Figures 3, 4, 5. and 6, walls 11, are similar in form. Being constructed so facilitates their being readily assembled or disassembled.

To flanges 21 and 23, is secured a guard and distributer plate 40. It being fastened in place by riveting to flange 21, and by bolting it to flange 23, as is indicated in Figures 3 and 6. Formed in said plate 40, are a series of openings or apertures 41, and outstanding bars 42, and an inclined distribute!" plate 43. As the washing fluid is being pumped up through the spaces 28, by the plungers 13 or 14, it flows out through the openings 41, and over plate 43, and onto the goods being washed.

In the sectional views, Figures 3, 4 and 5, is shown the arrangement of a pair of pumping plungers having the form substantially of that shown in Figure 8. But, in the modified form, as shown in Figure 6, a plunger substantially like that shown in Figure 9, is used instead. However, the principle of the operation of the two styles of plungers is the same. That is, as one of the plunger bars is being moved in an upward direction, the other is simultaneously being moved in an opposite direction, so that, in either case, when the plungers are being operated, the washing fluid is being alternately pumped up through spaces 28, first on one side and then on the other. And, as the upwardly moving plunger is lifting the fluid up and through openings 41, it simultaneously draws the fluid from the inner frame or receptacle 11, through the openings 30. But, on the downward movement of said plunger, the fluid, as having been drawn out through openings 30, into the space 28, is being forced back through said openings 30, and into the receptacle 11. And, since the deflectors 29, incline in the same general direction on either side of partition 27, the incoming fluid is thereby being deflected toward one side of the receptacle 11, causing a swirling motion of the fluid, which effects a general stirring up of the wash from one side of said receptacle to that of the other. The operation of spilling the fluid over the wash and forcing it back and forth in an upward and downward motion through the goods being washed effects a thorough cleaning of the goods in the wash in a comparatively short space of time without in the least danger of causing any injury of the goods even though they may be of the most delicate of fabrics.

In the arrangement of the driving mechanism for the style of plungers shown in Figure 8, and as installed in the manner indicated in Figures 3, 4 and 5, an intermediate driving gear 44, is being employed and arranged between two opposite intermeshing gears 45. Said gear 44, being mounted on a stud 46, which, is, preferably, mounted on end plate 34, by spot welding it in place. Said gears 45, l'iowever, are being fastened, as by a key pin 47. to shaft 48, which extends through a packing gland 49, and into an arm 13, of plunger bar 13, and there fastened as by a key pin 50. Directly opposite said shaft 48, and in line therewith, is mounted a bearing pin 51. and fixed in the manner indicated in Figures 4 and 5. to provide a bearing for the opposite end of plunger 13, and. in like manner, for plunger 14. Instead of having a pair of separate plungers of the style indicated in Figure 8, to work in space 28, it may be desired to have such style plunger as shown in Figure 9. The oppositely arranged plunger bars of which being connected at their ends to a pair of arms 14; formed in the manner substantially as shown in Figures 6 and 9. Vith such style plunger 14. it is only necessary to employ not more than two operating gears. Main driving gear 44, however, being mounted on shaft 46, out from the longitudinal vertical center of the machine, as is indicated in Figure 7, instead of on its center, as when style plungers 13 are being used. Driven gear is instead, mounted on a shaft 48'. which extends, in a like manner to shaft 48, through a packing gland 49, and into arm 14 at its axis 52. Shafts 46 and 46 are each being provided with a collar 53, having a key pin through it, with which to hold gears 44 and 44 in place.

Provided on gears 44 and 44, is a crank arm 54. It being connected in the usual manner to a connecting link 55, which, in turn, is connected to a crank 56, being mounted on driven shaft 57, of a speed reducing mechanism 58. Said mechanism 58, being preferably driven by an electric motor 59. Ihe arrangement and setup of same being indicated in the several views, Figures 2, 4, 5 and 7.

To drain the washing fluid from the machine, a pipe connection 60, is formed between a valve or faucet 61, and the spaces 28. It may be here stated that, for large commercial machines, a pumping device for automatically filling and emptying the machine may be provided, but, for household devices, as here illustrated, such additional mechanisn'i and expense would hardly be warranted.

In order to maintain the Washing fluid at a desired ten 'ierature during the process of *ashin electric heating units, 62, may be installed in the position indicated by dotted lines in Figures 3 and 6.

Over an opening 63, as formed by flanges 23, and end walls 34 and 34,, 35 and 35, is provided a hollow cover or closure 64, the same being hingeably mounted as at 65. On the inside of said cover 6%, are provided a multiple series of perforations 66, through which moisture may drain trom the washed goods when the same have been taken from the wash and placed on the cover when the same is opened to an inverted position as in.- dicated by dotted lines in Figure The cover ha a. lifting handle 67. provided thereon and fastened in place as by spot welding. Formed in the top of the cover, and on its longitudinal center, is a. conical outlet opening 68. the same being located. as shown in Figure 5, a desired distance from the axis of hinge pin 69. Said opening 69, being provided with a removable cap 70, which may be locked in place as in the manner ot a bayonet.

llqual to the distance of opening 66, From the axis of pin 6t), and in line with said opening, and on said center, is provided, in the top of casing 10, a flanged conically shaped drain outlet 71, which is provided with a pliable seat 752, and a removable cork or stopper 73. At the lower end ot said outlet 71. is fastened, as by spot welding, a bent tube 74, whereby connection may be made to a suction pinup through a door opening 75, being provided in the nd ot casing 10, as shown in Figures 4 and 5. Said opening 7!), being provided with a door or hinged closure 76. which may be locked closed by means of a padlock 77.

The operation of washing being conipleted. cover 64, is opened to its inverted position bringing opening 66, in cooperative relation with outlet 71. and forming a tight joint with pliable seat 72. The cover being arranged in this position and the washing placed thereon, substantially all the moisture being in the goods may be removed by making connection with tube 74, to a suction pump.

Tube 74, may be arranged in the position as indicated by bent tube 74', whereby the surplus moisture in the goods placed on the cover may drain back into the machine.

Having thus described my invention, it can be readily understood that the minor details of its construction may be altered in several ways without departing from the spirit and scope of the invention, and without losing any of its attendant advantages. Therefore, what I claim is desired to be secured by Letters Patent.
