ALBERT R. HAAG, or PEORIA, ILLINOIS WASHING MACHINE Application filed January 31, 1931. Serial No. 512,535.

This invention has to do with improvements in washing machines, being directed more particularly to machines for cleansing wearing apparel though applicable to the treatment of all types of work involving fabrics.

y The main object of the invention lies in producing a washing apparatus of a simple but exceedingly eflective type wherein the work to be treated is kept in constant motion and by which the portions of the work, or the several articles comprised in the treated whole, are kept separated from each other by which a quick and thorough cleansing is made possible.

Another object is to furnish a novel form of mechanism in a washing machine to which reciprocations are imparted and from which water streams are forced upon and through the materials under treatment.

Still another object lies in imparting a reciprocating action to a cavitied body while immersed in the cleaning fluid, so ordered and arranged as to force or pumpstrong jets or streams of the fluid through the work under treatment and by which the separate articles of the work will be kept in constant movement and thoroughly separated and thus more quickly cleaned.

'Further, an object is to provide in a washing mechanism an immersed reciprocating cavitied body that will act to force water through the work for cleaning the same rather than to operate upon the work 5 mechanically. 4

Again, an object lies in constructing a cavitied body to operate in a submerged position, so appointed that in the reciprocations imparted to it the churning fluid will be.

4 forced in streams or. jets under pressure upon the work at various angles whereby to accomplish quick cleansing due to the extreme turbulence of such fluid.

In addition to these objects invention is believed to lie in the novel arrangement of parts entering into the construction of the mechanism illustrated in the appended drawings forming part hereof though it is to be understood that minor changes may be made therein without departing from the aim of the invention, and as lying within the appended claims.

Figure 1 is a vertical sectional elevation of a washing machine which includes the present invention.

Figure 2 is an elevation in part section of a portion of the invention shown in Figure 1.

Figure 3 is a horizontal section of the machine produced in line 33 of Figure 1.

Figure 4 is an enlarged detail of a portion of what is shown in Figure 2, being an elevation.

Figures 5 and 6 are modifications of a wall structure, and

Figure 7 is avertical section of part of a wall structure shown in Figure 3 taken on line 77 of that figure.

The receptacle or tub for containing the work to be treated is represented at 1, and

this may be mounted upon any suitable support or stand 2 which may include a shelf 2 constituting a rest for driving mechanism to be described later.

' Erected in a central position upon the bottom 1' of the receptacle or tub l is a stem 3 provided with a bore 4. Said stem may include a base 5 by which to secure it. to the said bottom in any suitable-manner, the said bore 4 registering with an opening 6 in said bottom. A member taking the form of a cylindrical shell, in this instance, is identified by 5 and is erected'in the tub and secured in place beneath the base 5, for example, the whole arrangement being arranged that leakage of Water from the tub is prevented.

Within the bore 4 of the said stem 3 is a rod 7 having a length to extend above the latter and down through the bottom l, the lower end of the rod having one end of a pitman 8 connected thereto. The other end of the pitman has connection with the wristpin 9 of a crank-plate 10, for example, mounted on and rotated from the shaft ll ofa gear 11 housed in a gear-box 12, for example, a suitable power motor designated at 13 9 being belted to. and adapted for operating the whole, it being understood, however, that any other form of power arrangement may be used the whole purpose of which is to impart reciprocations to said rod 7. 10

Afiixed in an good manner to the end of the rod above the stem 3 is the upper end of a body or shell adapted to have reciprocations in a vertical direction with said rod. This body or shell in the present instance comprises acylindrical wall 14 greater in diameter than the shell or cylinder 5', there being a hood portion 15 mounted on the top of said wall in substantially a water tight manner from which arises a portion 16 secured to the stem 7 in any desired manner together with a deflector portion or bafile 17, the latter being provided by preference only, and may not be used. The only purpose of said baflle is that of preventing loss of water from the tub during the operation of the machine.

Below the lower edge of the wall 14 and afiixed to it is a portion 18 closed around a cylindrical portion or thimble 19 and afiixed thereto, said thimble adapted to work in a snug sliding fit upon the mentioned shell or cylinder 5, it being noted that the thimble has one or more holes 20 therein-above the member 18 or within the cavity of the described structure, said holes being used for drainage purposes only, and that there is a series of holes 21 in said cylinder conveniently located. I

The cylindrical wall 14 is provided in this instance with one or more series of holes 22, 23 which encircle said wall as best shown in Figure 3, see also Fi re 2. As will be pointed out in the description of the operation, water streams are to be projected from the holes 22, 23, and these said streams are to be directed preferably in a tangential direction, that is to say in a direction substantially tangential to said wall 14. It is to be here stated, however, that while said wall 14 may be cylindrical as described and shown it may, perhaps, be otherwise formed. The body may preferably be of larger diameter than the shell 5 in order that its wall 18 will impart added turbulence to the washing solution and the work as an assistance in the cleansing action.v In Figures 2, 3, 4 and 7, as will be seen, there is built out from the wall 14, at intervals, certain excrescences 14' through which said holes, or more properly passages 22, 23 extend in directions tangential to said wall, all of said passages of both rows being directed in the same general direction. Again, as shown particularly in Figure 7 the upper series 22 while directed in the manner described may also be directed upwardly, while the series 23 may be directed downwardly. While the described passages may be created as shown and described there are other ways of providing them in the wall 14. For instance, in Figure 5 the wall in a modified form may be perforated as at 142 and the metal at each of two sides may be distorted to provide a passage disposed at an angle to the surface from which the streams are projected. In Figure 6, as another form,

the wall may be formed with angular portions 14 in which the perforations 14 may be created with the same end in view. These different methods are described as showing that it is not the intention to be confined to 7 any one manner of accomplishing the desired -yond the wall 14in addition to which a flange 14 may lie between them. The two series of holes thus lie between these extensions.

Upon setting the mechanism in action through the motor 13 the rod 7 will reciprocate carrying with it the body 14,15, 18 the two extreme positions of the latter being shown in both broken and unbroken lines in Figure 1, said body being entirely submerged in the washing solution throughout its movements and consequently filled with such solution. In its upward stroke the solution is drawn into the body through the passages 22, 23 and the holes 21 of the cylinder 5, while in the downward movement the tendency to compress the solution results in pressure being created thereon by decreasing the cubic space in said body causing the solution to issue in strong streams or jets from said passages. Due to the inclination of the latter the solution will be given a rotary direction of movement around the tub. And since, also, the passages are inclined from the horizontal great turbulence of the solution results aided, of course, by the violent action set up by the body itself in its vertical movements, the treated work receiving the water jets into and through it, the extreme turbulence preventing the articles composing the work from becoming entangled and therefore exposed to through continuous cleansing action. The described flanges on the wall 14 serve to prevent the clothes being drawn against the openings of the passages 22, 23 at the time. the solution is drawn into the body, it being understood, however, that other means may be used that will serve a like purpose.

The number of passages 22, 23, or at least their total effective area and the area of the holes 21 of the cylinder 5 may be so proportioned that the solution while being drawn into the body and expelled during the action of the mechanism may also move into and out of said holes 21, such movement through the latter assisting in the desired turbulence, and means may be provided for preventing the work being drawn into holes.

Since the diameter of the body or agitator 14, 15, 18 is much less than that of the resaid I ceptacle 1 a wide annular space is provided between said body and the walls of the said receptacle for the free action therein of the solution and the work.
