WASHING-MACHINE.

To all whom it may concern-.- Be it known that I, JOHN S. PARRISH, a citizen of the United States of America, and a resident of Shadwell, county of Albemarle, State of Virginia, have invented certain new and useful Im rovements in Washing-Machines, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which Figure 1 is a vertical longitudinal section taken centrally through the casing. Fig. 2 is a vertical transverse section, and Fig. 3 a detail view, showing the inner face ofeone of the heads or end walls of the casing.

This invention has reference to that class of Washing-machines in which the casing is rotatably mounted on trunnions and is substantially cylindrical or barrel-likein shape, the trunnions being attached to the casing about midway its ends and one of the heads or ends being removable, as is well understood.

The object of my improvement is to provide an a paratus which shall be, exceedingly simple in construction andwhich at the same time shall provide the maximum rubbing-surface, and thereby not only increase the efficiency of the a paratus, but-also reduce the time require to effect a thorough cleaning of the clothing, as more fully hereinafter set forth.

To the accomplishment of this object and such others as may hereinafter appear, the invention consists of the arts and combination of arts hereinafter lly described, and particul drly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part of this specification, in which the same reference characters designate like parts throughout the several views.

Referring to thedrawings by letters, A designates a barrel-shape casing mounted upon the trunnions a, which are journaled in any suitable mannerin a supporting-frame b. I prefer usin a folding frame of the wellknown type; ut it is obvious that I may employ a supporting-frame of any construction. The trunnions are, as usual, fastened to the exterior of the casing about midway its ends.

One of the heads B is, as usual, fastened stationaril in the end of the casing, while the other ead B is removably fastened. in place by any of the well-known clamp devices. Each head is provided with a series of parallel rubbing-bars c, fastened on its in- Specification of Letters Patent.

ner face and lying parallel with the axis of rotation of the casing. The projecting edges of these bars 0 are beveled,'as shown, to increase the rubbing action on the clothes.

The casing is divided into two compartments by a central partition consisting of separated bars (1, whose opposite edges are beveled off to increase the rubbing action on the clothes. These bars lie parallel with the bars 0 on the heads. This partition is divided into two semicircular sections D D, hinged together at e, the hinges being located on the side nearer to the removable head B. The section D is fixed stationarily to the inner side of the casing-wall, while the hinge-section D is locked in place by turn-buttons F, pivoted on the inner side of the casing and adapted to clamp this hinge-section against a stop-strip g, fastened to the casing. Of course any other suitable devices may be employed, if desired.

In charging the machine sufficient suds is poured into the casing to fill its lower section about three-fourths full. Then the hingesection D is raised and about one-half of the batch of clothing that is to beoperated on is dropped into the lower compartment, and th eHtinge-section is then closed and latched in place. The remaining half of the clothing is then dro ed in upon the partition, and the removah e head is then clamped tightly in place. trunnions at a moderate s eed about six or eight minutes, whichusual y suffices toxthoroughly clean a batch of clothing of the average character. As the machine is turned over and over the two separated batches of clothingare tumbled about, being thrown 'first against the rubbing-surfaces on the heads and then a ainst the rubbing-surfaces of the partition, t ereby subjecting the clothing to a thorough but uninjurious pounding and rublocking or latching The machine is then rotated on itsv bing. As the two batches of clothing alternately strike a ainst the partition the soapy water will be dashed through the meshes of ioo the fabrics in the act of passing from one 1 I compartment to the other.

rotation of the barrel at a moderate speed is not sufficient to overcome the gravity of the suds and the clothin so that the batches of clothing will strike t lie o posite sides of the partition with considerable force.

The rubbing action of the bars is materially increased by having them parallel with the axis of rotation, as is apparent, and by The centrifu al force given to the batches of clothing by t e dividing up the clothing into two separated l batches the loaded apparatus is approximately evenly balanced, thereby contributing to ease of operation.

As will be observed, the essential feature of the invention lies in alternately dashing the water through the clothing as the water and the clothing strike the partition, this operation being kept up continually during the rotation of the casing. in this way the clothing is quickly cleansed without subjecting it to injurious rubbing. In order to obtain the best results, the clothing to bc washed should be soaked in cold water from one to two hours at least before placing it in the machine. Watcr of medium temperature is used, and a suitable quantity of soap is cut up fine and dropped into the water. Then by rotating the casing a few times sufficient suds will be produced. As stated, six or eight minutes rotation at moderate speed will accomplish the washing of the clothing The suds is then drawnoff through a suitable cock, and then the same amount of hot water without soap is put in. The clothing is removed before this hot water is poured in and is wrung out and is then put back in the casing Then the casing is again rotated for a sufl1- cient time to thoroughly rinse the fabrics. Of course the a paratus may be used in any other manner the exigencies of the case may re uire. t will be apparent to those skilled in the art that various mechanical embodiments of the invention are possible, and I therefore do not wish to be limited to the exact arrangement and construction shown.

What I claim, and desire to secure by Letters Patent, is

1. In a washing-machine of the type described, the combination of a support, a barrel-like casing 'pivotally mounted thereon about midway its length, one of the heads of this casin being removably fastened in place and both heads being provided on their inner sides with rubbing devices, a central partition in the casing constructed of two semicircular sections, one being stationary and the other being hinged to this stationary section, and both sections consisting of spaced bars, said hinged section being adapted to swing toward the removable head, and means for locking the hinged section in place, for the purpose set forth.

2. In a washing-machine of the type set forth, the combination of a support, a cylindrical casing mounted thereon upon trunnions attached to the interior of the casing about midway its length, one of the heads of the casing being reinovably fastened in place and both the heads being provided with rubbing projections on their inner faces, a central partition in the casing provided with numerous water-passages and rubbing projections on its opposite faces, a part of this partition being movable toward the removable head, and. means forlocking this movable section in place.

3. In combination with a rotatable casing, the casing being substantially cylindrical and the axis of rotation transversely through the center thereof about midway the length of the casing, said casing being rovided with under walls or heads one of which is removable, and a partition extending across the interior of the casing approximately in line with its axis of rotation, this partition con sisting of numerous slats or bars having water-passages between them, a part of the sec tion being movably held in place, whereby access may be had to the clothes-chamber on the opposite side of the partition from the removable head, substantially as set forth.

In testimony whereof Ihereunto affix my signature in the presence of two witnesses this 12th day of April, 1905.
