CHARLES G. MENK, OF CLEVELA MACHINERY I To (1 whom it may Be it known that COMPANY, OF

ND, OHIO, ASSIGNOR TO THE AMERICAN LAUNDRY CINCINNATI, OHIO, A CORPORATION OF 0310..

WASHING MACHINE.

Application filed August 12, 1921.

I, CHARLES G. MENK, a

citizen of the United States, residing at Cleveland, in the-county of Cuyahoga and State of Ohio, have'invented certain new and useful Improve chines, cation.

of 'which the following ments in ashing Ma- 1s a specifi- This invention relates to washing machines and particularly to machines of this type utilizing a revolving barrel or drum.

Heretofore it has been struct the outer wall of the practice to conthe drum or cylinder of a washing machine of a plurality of staves extending from one end to the other and to provide such staves with perforations adapted to permit tl water into and out of of wood for the purpose to the cylinder as a whole.

staves-are usually of lending rigidity 1e ingress and egress of the cylinder. These and also for the purpose of preventing injury to the garments or clothing. One disadvantage accompanying the use of a continuous arrangement of staves for the outer wall is the fact tha t there is-not sufficient capacity in the perforations to allow the proper amount of water to .pass in and out and it is impossible to increase the perforations without weakening the staves.

The present invention therefore aims to overcome the above structingthe barrel disadvantage by conor cylinder of a' plurality of perforatedwooden staves interrupted around the periphery of the cylinder by incorporating -in the wall plates formed of wire mesh a series of staves or mesh. These wire staves are spaced at regular intervals among the wooden staves and serve to not only permit the free ingress andegress of water, but also to serve the wooden staves to in conjunction with positively direct the water into and out of the cylinder.

Another feature of the invention is the feature of arranging the hinges for the door and the door itself in a manner such that projecting parts from the hinges and door are reduced to the minimum so as to allow.

the minimum amount of clearance between the cylinder and the outer casing or tub thereby reducing the quantity of water utilized and obtaininga more eificient washing operation.

The invention may be further brieflysummarized as consisting in the construction and arrangeme nt of parts hereinafter Serial No. 491,705.

set forth in the following description, drawings and claims,

Referring to. the drawings, Fig. 1 is a transverse section through the machine; Fig. 2 is-a view of the drum partly in elevation and partly in section; and Fig. 3 is a sectional View on line 3-3 of Fig. 2 show ing a part of the outer wall structure in section and one ofthe intermediate heads or diaphragms in elevation.

In the drawings, which represents one embodiment of the invention, 1 represents a suitable support for the outer tub or casing 2 of a well known construction and arrangement and requires no further detailed description. Rotatably mounted within this casing or trunnions4 mounted in suitable bearings not shown in the ends of the casing or tub 2. This is the usual construction. Secured to these heads 3 are longitudinal staves 5, preferably of wood, provided with perforations 6 and arranged in pairs as shown in Fig. 1 except 'at'the door opening as will appear. These pairs of staves serve to unite the end heads and provide a rigid structure for supporting the clothes and for permitting the driving of the cylinder or barrel as a unit. In some instances, the cylinder or barrel may be increased in length and provided with intermediate heads or diaphragms 7 secured in suitable notches or recesses 8 in the staves. The staves are; held in place by bands or straps 9 passing around the drum over the end heads and over the in; termediate heads or diaphragms.

. The construction already described is on which is well known in the interruption of the continuous arrange ment of staves and it is the provision of this interruption and the arrangement of wire mesh staves or plates between the pairs that constitutes the subjectmatter of a part of this invention. The edges of the staves adjacent the spaces are cut back to form longitudinal recesses 10, as shown in Fig. 1-, and these recesses 10 in the adjacent edges at each opening receive flanges 11 turned outward from the longitudinal edges of Wire mesh staves or plates, 12. These Wire mesh staves are made up of rather coarse mesh to provide ample water passage capacity and are fine enough to prevent the catching of buttons or clothing in the openings. The

practice except for tub is the barrel or cylinder" made up of suitable end heads 3 having wire-mesh serves to provide an undulating surface against which the materials treated are rubbed in the manner of a wash board and assists in the washing operation. The edges of the wood staves adjacent the open ings also serve to directwater or washing fluid into and out of the cylinder.

' At suitable intervals the inner surface of the wall of thebarrel or cylinder is inter rupted by baffies 13 of the usual form.

-At one point in the periphery and adjacent one of the baffles 13 is a suitable door opening arranged between the baflie 13 and a door supporting member 14. The two members 13 and 14 at this point are provided with shoulders 15 against which the door is clamped. These shoulders 15 are lowered sufiiciently so that the door, which is made up of door staves 16, rests below the outer surface of the wall of the barrel or cylinder. The door staves 16 are securely fastened to door straps 17 having hinge eyes 18 connected by a pintle to eyes 19 forming a part of -a hinge strap 20 secured to ,the outside of the wooden stave adjacent .to the door support 14. The eyes 18 and 19 are so arranged upon their straps that the strap 17 describes an arc of smaller radius than the strap 20, whereby the door is free to seat within the sockets, the inner nuter periphery of the barrel or drum, In knuckles are projected this way the hinge inward into the drum structure and do not project beyond the periphery of the drum or cylinder and the casing of the tub thus reducing the quantity of Water necessary and resulting in a saving of washing compound.

What I claim is:

1. In a Washing machine barrel or cylinder, end heads, a plurality of longitudinal staves arranged to spaces and having their edges seated in said surfaces of said staves and wire mesh members being of substantially the same curvature.

2. In a washing machine barrel or cylinder, end heads, a plurality of longitudinal staves arranged to provide intervening spaces and having sockets in their edges, and wire mesh members having outwardly turned flanges along their edges seated in said sockets, the inner surfaces of said staves and wire mesh members beingof substantially the same curvature.

In testimony whereof I hereby affix my signature.

CHARLES G. MENK.

provide intervening. spaces and having sockets in their edges, and wire mesh members arranged in Said.
