Specification of Letters" Patent.

Patented Sept. "17, 1918.

Application filed February 18, 1918. Serial No. 217,793.

To all whom it may concern: Be it known that I, HERMAN NIEMAN, a

. citizen of the United States, residing at class 0 Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Washing- Machines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in washin machines and particularly to that ing inner receptacle, such for instance as tubs of the character commonly used in steam laundries, hotel laundries and the like. One of the objects of the invention is to provide improved means whereby the standard steam laundry tub may be divided into compartments, each compartment being adapted to contain a specific class of articles to be laundered, or the laundry belonging to one family or person, thereby saving time, trouble and expense in marking, recording and subsequently assorting such articles, and at the same time enabling all the clothes of a family or individual to be washed an kept to ether.

Anot or object is to provide an improved division member or partition that is removable and is also hinged? mounted at its rear 1 end so that its forwar end may be swung upwardly across the opening of the tub to permit access to the space in the tub beneath the partition. I

Other objects and advantages will appear from the detailed description and claims to follow and from the nature of the apparatus itself. 4

For the purpose of disclosing my invention, I have illustrated one embodiment thereof in the accompanying drawings, in which Figure 1 is a vertical transverse sectional view taken on the line 11 of Fig. 2;

Fig; 2 is a substantially axial sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a sectional detail on the line 33 of Fig. 1;, and

Fig. 4 is a detailed sectional view showing the means for holding the dividing member in raised position.

In the embodiment of the invention illustrated, there is the usual stationary cylinmachines wherein there is a rotatthrough which access may be had to the interior of the casing, this opening being covered by a sliding cover plate 7, which may be closed when the tub is in operation. Mounted within this casing, which is large enough to contain what may be termed two rotating tubs, are a pair of rotating tubs preferably constructed with a pair of circular heads 8 having mounted thereon supporting shafts 9 journaled in the heads 10 of the outercasing; One of these shafts, on

the exterior of the casing, may be provided with a suitable driving gear 50 or be connected. otherwise to the tub-driving mecha-v nism.v Securedto these'heads 8 are a series of staves 11 thereby forming an elongated wood cylindrical rotating tub, mounted and rotating within the casing. These staves 11 are placed adjacent one-another and are provided with suitable openings 12 to permit the hot suds or steam to enter the inside of the tub from the outer casing. This tub cylinder is divided in half, or into two tubs, by means of a central circular head 13. Straps 14 surround the tub to bind all parts together. At regular intervals in the circumference of the tubs are providedbafl'les l5-projecting radially into the tub or tub cylinder. These bafiles are secured in place by keepers 16 attached to the walls 8 and 13 (F ig; 3), and provide projections which catch the clothes and serve to lift the same as the tub is rotated, until the clothes drop or roll off back into the hot suds. Each of the tubs is provided'with a door 17, preferably consisting of a section of the casing cut out and hinged at 18 so that when the door reaches a position opposite the opening 6 its lower edge may be raised to permit access to the interior of the tub. This door is preferably made of the same width as the tub and is held shut in operation by means of suitable slidebolts 19.

It is desired on the part of laundries in certain instances to separate the clothes to be laundered into different batches and to keep them so separated during the launder ing process, as, for example, the laundry of' one family. Heretofore it has not been practical to wash the clothes economically in this manner. The laundry tubs are usuall so large that it does not pay to wash a sma l batch of clothes in one tub. To obviate the objection, such separate batches have been placed in bags, but this is objectionable for various reasons.

In order to overcome this objection, I provide a means whereby the tubs may be d1- vided diametrically into compartments, this means being preferably adaptable for use in connection with the standard form of laundry tub now in use,-and so designed as to be applied to the standard tub without changing the construction of the tub or without disassembling it, and readily removable so that the tub can till be used in the old Way.

In order to so divide the tubs into sections, a removable dividing member or partitlon is provided, which preferably is in the form of a frame comprising two sidemembers and the end members 21, between which are secured aplurality of round bars or rods 22,

' These rods may be placed close together or may be suitably spaced apart as desired. These rods provide on the-opposite faces of the division member thus formed a corrugated rubbing surface for the clothes, similar to the ordinary hand wash-board. This frame is supported in position in the tub between and in the plane of two oppositelydisposed baflleg 15. To the opposite sides respectively of the side bars 20 at one end v of the frame are secured a pair of metal strips 23 having splayed rojecting ends that straddle one of the ba es 15, as clearly shown in Fig; 1, whereby this end of the frame is held in position so that it will not move during the rotation of the tub; at the same time it is hingedly or pivotally, as well as removably, mounted so that its front or opposite end may be raised. The opposite end of the frame is supported on the op-.

posite baflle 15 through the agency of flat metal strips-24 secured to the upper sides of the side bars, 20 and projecting beyond the ends of the latter sufficiently to rest directly on the bafile 15. To prevent the frame from becoming displaced at this end, I provide stops or abutments 25 on the inner face of the door 17 which, when the door is closed, take a clamping position over strip 24 so that the front end of the frame is held between thes'e abutments 25 and the baffle 15.

, the tub is in its normal position, that is the to permit placing clothes in or removing position with the'doo'r lTopposite the openmg 6. In lJhlS' position with the door 6 open, the frame or division member may be raised them from the bottom compartment, the frame being held in its raised position during these operations by means of a suitable spring catch 26 formed in one head of the tub, as shown in detail in Fig. 4.- After the clothes have been deposited in the bottom of the tub, the frame or division member may be lowered and an additional batch of clothes deposited in the top of the tub, after which the door 17 is closed and the cylindrical tub started to rotate in the usual manner and at the usual speed. It will be seen that as the tub rotates, the clothes will be picked up from the bottom by the baffles 15, eventually dropping by gravity on one end of the division member and sliding along this division member toward the opposite end and bottom of the tub again, so that a rubbing action of this division member-on the clothes constantly takes place during the washing operation.

Of course the invention may be applied to single tubs as well as to double ones like those shown, and to various forms and types of tubs, and to tubs of various materials, and the division member itself may be constructed in various ways and of various ma terialsand be secured in position in the tubs in varlous ways, all without depart ng from the spirit or scope of the invention as set forth in the following claims.

. I claim 1. In a laundry tub, the combination with a casing, of a rotatable tub mounted within said casing and having an opening to permit access to the interior thereof, and a dlViSiOIl member extending diametrically "entirely across said tub, said member being removably mounted therein and hingedly support-' ed at the end opposite said opening, the end adjacent said opening adapted "to be raised and lowered for access to both compartments of the tub.

2. In a laundry tub, the combination with a rotatable cylindrical casing having an with internal baflies, of a removable partition dividing said casing diametrically into compartments, said partition at one end of said baffles and at its other end supported by a diametrically opposite baflie, and means on said cover for locking said partition in place on said last namedbafiie when the cover is closed.

4. In a laundry tub,the combination with a rotatable cylindrical casing having an opening in its circumference and provided opening in itscircumference and providedwith internal bafiies, of a removable division member extending diametrically across said casing, said division member having at one end a pair of forwardly projecting splayed strips'straddling one of said bafiles whereby it is loosely and removablyhinged to the latter, and means to hold the other end of. said division member stationary. v

5. In a laundry tub, the combination with a rotatable cylindrical casing having an opening in its circumference and provided with internal baflles, of a removable division member extending diametrically across said casing, said division member having at one end a pair of forwardlyprojecting splayed strips straddling one of said baflles whereby it is loosely and removably hinged to the latter, and at its other end a rearwardly projecting strip adapted to rest upon a diametrically opposite bafiie;

6. In a laundry tub, the combination with a rotatable cylindrical casing having an opening in its circumference and provided with internal baflies, of a hinged cover for said opening, a removable division member extending diametrically across said casing, said division member having at one end a pair of forwardly projecting splayed' strips straddling one of 'said'bafiles whereby it is loosely and removably hinged to the latter,
