LAUNDRY-*WASHING MACHXNE.

iii-:1w alle Application filed May 19, 1313. Serial No. 768,503

To all yohm/L it 'may concern Be it Vknown .that l, JOHN W. Bnncaw, a citizen ot the United States, residing` at Haniilton, in the county ol' Butler and State of Ohio, have invented certain new and useful .improvements in Laundiy-Vlfashing Illachines, of which the following is a specilication.

My invention relates to an improvement in a laundry clothes fashing machine.

The object of my inventio'n is to provide means eti'ectively counteracting this-entangling influence, and which will so manipulate the clothes as to prevent their inter-knotting, whereby the time ordinarily required for nianual disentanglement is saved and the nnaneiit-rending action of the machine eliminated. l

Another valuable result produced is a dis tinct increment inthe cleansing etliciency of a machine embodying my improvement and a consequent i'naterial reduction in the time required for washing a given load.

The features of my improvement will be more fully setforth in the description of the accomlmnying. dra-wings, forming a part of this specilication, disclosing' the preferred embodiment of my invention, in which Figure l is a .ront elevation ol owns-hing machine showing the inner cylinder door opened to exhibit my improvement. as applied. Fig. 2 is a central vertical section through the inner cyinder. Fig. 3 is o pen spcctive view ci a detached clothes manipuf 'lining member partly in section. Fig. e is a plan view, partly broken away, of a detached ,interior element of 'the clothes manipulating member.

The hollow, horizontal cylinders i and 2, form the tulo and' washer of the machine. The tub is stationary aand the perforated washer cylinder rotatable therein, each provided with adoor in the usualmanner, the inner cylinder door beine; shown in F l and The inner cylinder is rotatably sul'iported in the tub and may be suitably driven by co1mec-,tintl :trom a source of power to the. driving wheel 20, and axial shaft 30, there beingl a clearance space between' the tub and inner cyli The clothes in washh men" i lhed in n Jr nl the peritolt preferably torete bese 5,

to which is attached theholl'o-w ribX 6, pret erably formed ot' sheet metah'flanged at its adjacent ends T tor attachment to the base 5. VThe chamber so formed is preferably wider at the base, having a rounded noselike end to engage the clothes, projecting radially toward the cylinder axis. lVithin this chamber is placed a reciprocating` valve- 'functioning member'S hinged at the medial longitudinal line of the base by means of suitable connectimis'l()7 its end terminating in the project-ing end of said chamber, the walls of which are formed with inlet orifices 9 at the hase, and the outlet orifices l0 in proximity to the clothes enga ing end. The unitary member so formed 1s suitably secured to the inner surface of the washing cylindre. lVhen two members fl are en1- ployed, as shown, l preferably dispose them diametrically, with the first member placed, say 8 or 1'() inches below the lower lsill of the cylinderdoor, so that the clothes will lie under said members in the bottom of the cylinder when brought to 'door-opening position.

l pre-fer the unitary structure illustrated, not only becauseof its convenient assembly into an ,organized machine, for factory manufacture, but because it can be shipped or applied as an accessory element to commercial machines of this general type, its use be-` ing obviously not restricted to a double cylinder washing machine, but 'being broadly applicable to Various kinds ot washing tubs.

@t course the segi'nental base could be omitted, and the chamber liormed by the sheet metal structure could be attached directly to the inner cylinder, but l prefer that the Hoor oir this chamber should be impert'orate in order to more reliably affect the contemplated water flows through the orifices 9 and l0.

ln practice, the wash water stands in the tub appreciably below the axial line, and 'the inner cylinder carries a proportionate load of clothes, lthe inner cylinder being rotated periodically 'in opposite directions. Assuming,` the direction of a given rotation to be as indicated by the arrow, Fig'. 2, the ymember 8 will hare moved on its hinge to bringits vthe member 8 will swing to the other ,i to dislodge or disentangle theclothes,butm'a..

"prevented from entanglement,

terially increasing the cleansing eiiiciency by eifectively dashing the Wash Water against the clothes when carried above thewater level, serving also to increase the Water agitation and inducing maximum Water Hows und currents. Preferably the end of the member 8 in its extreme position will alternately cover the orifices 10, first on one side and then on the otherv side of chamber 4, causing the orifices 9 to function generallyT as inlet, and the orifices 10 as outlet' ports for the Water. The clothes are thus not only but are thoroughly subjected to additional washing treatments, and agitation, with minimum knotting and rending influences.

Having described my inventioml claim 1. An attachment for .a washin machine comprising base, or hollow ri formed with Waterinlet and outlet orifices, and a single member-hinged' to the base with its free end extendin into the clothesengeging endof said vri land Swingin#r from one side to the other of seid hollow rib when the base revolves around an axis.

2. An attachment for e washingv machine comprising u'segmental imperforate base, e

lhollow rib ythereon formed with inl t and outlet orifices near the base and clothes-engaging rounded end respectively, and e -single valve-functioning member pivoted to un intermediate portion of the base Within kthe chamber formed by seid rib,`with its free end movablefrom one side of the chamber to the other in relation to said orifices.

In Witness whereof, I hereunto subscribe my name, as attested by the two subscribing witnesses. l
