ATTORNEYS Patented June 14, 1932 UNITED STATES PATENT OFFICE FRITZ IBALZER, OF CINCINNATI, OHIO, ASSIGNOR TO THE AMERICAN LAUNDRY IA- CHIN ERY COHPANY,'OF. CINCINNATI, OHIO, A CORPORATION OF OHIO WASHING MACHINE Application filed August 21, 1930. Serial No. 476,754.

My invention relates to fabric treating apparatus and particularly to washing and dr cleaning machine cylinders.

he present invention relates to cylinders having radial partitions for the purpose of extending V shaped perforated portions for admitting water or other cleaning liquid into the cylinder, one side of each V shaped portion being formed bythe radial partitions and the other side being formed by a sepa- L" rate member connected to the radial partitions and to the cylinder sheet.

It is one object of this invention to provide a cylinder of such construction that a load or batch of material in any compartment will operate as a valve during the major part of the treating operation by lodging against the perforated areas to close the perforations and thereby trap the treating liquid in the compartment and cause it to remain with the load in the compartment to prolong the treating operation for substantially the entire distance of travel of the compartment in a single rotation of the cylinder.

By such an arrangement, the batch or load in any one compartment is progressively submerged in the liquid at the bottom of the cylinder, is then spread out in the liquid in the cylinder permitting a penetration of the treating liquid, and thereafter crowded with a squeezing action in the presence of the trapped liquid in one corner of the treating compartment. Then, as the particular compartment continues to travel in its path around the central axis of the washing cylinder the batch is lifted by a suitable baflie provided for that purpose and caused to tumble into a pool in another corner pocket of the compartment where further crowding and squeezing action is produced in the presence of treating liquid. As the cylinder continues to rotate, the liquid from the compartment is discharged into the outer tub or casing and an additional supply drawn in, the batch of materials being separated and distributed through the new supply and being subjected to a sequence of treatment steps as hereinbefore set forth. 7

Various other objects and advantageous features of my invention may be seen in the following description and one embodiment thereof may be seen in the accompanying drawings wherein similar characters of reference designate corresponding parts, and wherein:

Fig. 1 is a perspective view, partly broken away and partly in section, of awashing machine embodying my invention; Fig. 2 is a sectional View of the machine shown in Fig. 1; Fig. 3 is a detail view of the perforated V shaped inlet to and outlet from the washing machine cylinder; Fig. 4 is a sectional View showing a modified form of cylinder compartment structure; and Fig. 5 is a View similar to Fig. 4 showing a still further modified form of cylinder structure.

Referring to the drawings, I have shown a washing machine consisting of the usual tub or outer casing 1 supported on a suitable frame 2 and provided with an upper opening 3 having a closure 4 and a lower opening 5 having a closure member 6 that takes the form of apsliding apron. WVhen the machine is being unloaded, the closures 4: and 6 are opened whereby the load from an inner rotatable container 7 can slide out through the lower opening 5 and into some form of conveying means if desired. However, the construction of the tub or cylinder 1, constitutes no part of the invention and may be of any desired form.

In accordance with my invention, the container or cylinder 7 which is rotatably mounted within the tub or outer casing 1 comprises end heads 8 that are, in this instance, impcrforate although they might be otherwise. An outer cylindrical wall that is made up of sections is secured to the end heads 8 in any desired manner and one edge of each section is secured to the outer edge of a radial par- 10 that is more or less of yramid form and coextensive with the lengt of the partition to which it is attached. Such baflles are arranged on the partitions e adjacent to but sliightly separated from the center of-the cylin er at which point the partitions join and serve the purpose of retardi or holding back the work within the cylin er so that mstea' d of simply sliding outwardly along the partition uring rotation of the cylinder the work is tumbled so that all arts thereof come in contact with the treatmg fluid at sometime during the washing or cleaning operation, during which time the work is retained in the cyhnder. While each com ent is provided with but one of the aflles, nevertheless this batfle acts in practically the same manner in both directions of rotation of the cylinder.

It will be noted that the partitions 9 adjacent their point of connection with the edges of the sections which go to make u the inner cylinder wall are perforated an that perforated plates 11 extend angularly 25 outwardly from the partitions 9 and from a point at which the perforated portions of the partitionsend, these plates havin their outer edges secured to the opposite as of the sections which make up the outer cy der wall. The rforated portions of the partitions 9 an the angularly extending plates 11 form V shaped openings by way of which liqm'ld within any one complartment in the cy der may travel outwar y into the tub or outer casing or liquid from the tub or outer casing may enter the compartment. f

For convenience and as is usual'in cylinder construction, the cylinder is provided with doors 12 and 13, the only difierence being that each com artment in this instance is rovided with suc doors whereby work may placed within each compartment or removed therefrom.

In the operation of'this device,;the work in any one compartment is subjected to several crowding, squeezing and separating o rations in the bath of treating 'quid whic results in several separate penetrating efi'ecte tion. The crow ing and squeezi action is brought about by the work tum into the corner of the compartment which 18 first lowered, de upon the direction of rotation of e cyhnder wheieb the weight of the work and the centrifug'zl force tends to extract the treating 1i uid erefrom. At the same time, the wor by covering the perforated portion of the corner, acts as a valve or closure for the perforations and as prevents the escape of treatinslliquid from the compartment throughout or at least the greater portion, of the rotation of the glinder, whereby the work is subjected to V e same treating liquid a number of times.- By the use of partitions that are imperof the treating li uid throughout one revolu- 1,eea,eea

forate throughout their greater portion and the action of the work on the perforated portion, liquid from any one compartment ma not easily enter another com artment to us carry undesirable materials om one compartment into another. However, liquid from any compartment may dischar into the outer tub or casin at certain points in the rotation of the cyhnder and the undesirable material be allowed to settle into or be gathered in traps such as are normally used with washing machines of this type. Likewise, treating liquid from the outer tub or casing will haveample time to enter the compartment whereby the work therein may be sullageected to a fresh supply.

ferring to Figures 4 and 5 of the drawings, I have shown modified forms of cylinders wherein the partitions are so connected at their ad'acent ed or so formed that the angle of t e artitlon will be increased so as to more e ciently unload the machine through the lower a ron or door 6 of the outer tub or casing. n Fig. 4 the ad'acent edges of the partition 9 are so connec as to form atriangular space 14 while .in Fig. 5 the partitions are bent near their adjacent edges so as to increase the angularity of the greater portion of the partitions.

With the construction shown a cylinder is provided in which workis su jected to a series of crowding, tumbling and squeezing actions during one rotation of thecylinder whereby the work is more eflicientl cleaned with a lesser amount of treating stead of being merely rolled over and over as it would be in the usual perforated cylinder having no partions or .bafies therein.
