WILLIAM H.' THOMPSON, OF BURBANK, OHIO.

WASHING MACHINE.

Application filed may 11, 1922. Serial No. 560,283.

To all whom it may concern:

Be it known that ,1, WILLIAM H. THOMP- SON a citizen of the United States, residin at l3urbank, in the county of Wayne an State of Ohio, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

My invention relates to improvements in washing machines, the present embodiment more particularly to that class or type in w ich a washing cylinformation is rotatably mounted der of open fixed body or casing forming in a relatively a suitable receptacle for the washing or cleansing liquid within which the cylinder is adapted to rotate. The invention further relates to that class or type in which suitable movable plunger members are provided with vacuum creating devices or cups adapted to move against and press the clothes to be washed and then move away from the same to create a part1al vacuum or suction action, the improved washer being adapted to combine the functio of theordinary cylinder washer with thos of .the ordinary clothes pounder type.

The primary object of the invention is to provide a generally improved washing machine of the type or class indicated which will be exceedingly simple'in construction, cheap of manufacture and efficient in use. A still further and very important object is the provision of oppositely arranged vacuum creating pistons in a washing cylinder adapted to be simultaneously moved toward and from each other to successively press and create a partial 'vacuum in the inter- E Wit the above mentioned and other ends posed clothes batchwithin the washing cylinder with each complete stroke or reciprocation of the pistons or plungers.

A still further object isgthe provision of improved means for simultaneously driving or rotatin the washing-cylinder and recip rocatin t' e pistons during the retationjof such 0 der.

in view, the invention consists in the no'vl construction, arrangement and combination of parts, hereinafter described, illiistrated in 'one of its embodiments in the accompanying drawings and particularly pointed out in the ap endedclaimsj eferr'ing to the-drawings, forming a part of' this specification, Figure 1 is a side elevation, partly in section, of a washing machine constructed in accordance with this 1nven tion, the clothes pressing and vacuum creating pistons being at their innermost positlons or the inner ends of their inward working strokes preparatory to being moved in an opposite direction or away from each other for producing a partial vacuum or suction in the interposed clothes in the washing cylinder.

Flg. 6, an enlarged plan view, partly in sectiornof one of the piston stems connecting a'nd actuating yokes andthe rotary piston actuatin or driving member therefor, the dotted lines indicating the relative position of the parts in the extreme opposite end of the working stroke or position thereof.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The mproved machine comprises a suitablecasing or housing 1, forming a receptacle for the washing liquid and within which the washin I cylinder of. open formation is 'adapte to rotate, as hereinafter referred to.

or housing 1, is mounted on a The casin frame or support the latter suitable being provided with suitable support ing legs or columns 1*. The top of the relatively fixed casing or housing 1 is provided w'th a suitable opening adapt- 4 ed to be opene and closed throu h a suitabledoor or closure member 1*, a ording ac cess-to the interior of the washing cylinder, as hereinafter referred to. 1 p

The washing cylinder is of open formation, the outer periphery, in the present instance, being made up of a pluralityof suiting provided with trunnions 2", rotatably mounted in suitable bearmgopenings in the ably spaced slats or strips 2, connected at' their ends to cylinder heads 2', the latter be-' are casing or housing ends or heads 1. The outshown most clearly in Fig. 5 of the drawings.

As a means of driving or rotating the washing cylinder one of the trunnions 2 is provided with a gear wheel 3, meshing with a pinion 4, carried on a power shaft 5, the.

latter, in the present instance; being pro vided with a sprocket wheel, adapted to .be driven by means of a sprocket chain 6, leading to a sprocket wheel on a motor shaft 7',

' of a motor 8.

washing machine of this type the functions of the washer of the clothes of the washing cylinder, said pistons or pounder type, and particularly as a means of PI'OVldlIlg vacuum or suction creatlng devices in opposed relation and engaging.

the'batch of clothes on opposite sides as ro tatedwithin the washing cylinder, the latter is provided with longitudinally movable vacuum creating pistons or plunger heads. 9, movable longitudinally of the axis '.heads 9 being provided with suitable vacuum or suction creating devices adapted to engage opposite portions, of the clothes batch when moved inwardly toward each other and to create a partial 'vacuum when.

moved outwardly away from each other.

vin opposed relation to each other.

In the present instance, such" vacuum or suctlon creating devices are 1n the specific form of funnel or cup shaped members 9,.

having their open or flaring ends extending toward each other and preferably arranged The smaller ends of the cup members 9f" are mounted in suitable openings in the plunger terposed batch of clothes.

As a means of limiting the outward or open movement of the valves 9*, the valve I stems 9 may be provided with stop projections 9, adapted to engage with the neck portions of the cups as the latter are moved toward each other whereby the cups are open in operation of engaging and pressing msaaea the opposite portions of the clothes batch. The clothes pressing and vacuum creating pistons 9 and cups 9 are spaced apart a suitable distance to provide an intermediate clothes washiichamber 10, and as a means .of simultaneously reciprocating the pistons- 9, the latter are provided with piston stems 9, extending through suitable openings 2, in the trunnions 2 (the latter being preferably of tubular formation as shown), the

-outer ends of the piston stems 9 preferably terminating in heads 9 ,'detachably and rotatably mounted in bearing sockets 11, of yoke members 11, the sockets 11 being closed by means of threaded caps ll". As a means of preventing the rotation of the yoke members 11, the latter are provided with guide stems 11, extending through guide or bearing heads 12*, of bearing brackets 12, extending outwardly from the ends of the washer supporting frame, the.

gearing for actuating the pistons and pisi ton stems being preferably enclosed in a .As a means of combining with the ordlnary washing cylinder function of the ordina protecting casing 13, at each end, as shown most clearly in Fig. 1 of the drawings. As the piston stem connecting and actuating yokes and the gearing mechanism therefor are alike and arranged'inopposed relation to each other in the end casings 13,-one set of yoke and gear mechanism need onlybe shown and described.

Asa means of actuating each yoke 11 and the connected pistons simultaneously with the rotation of the washing cylinder, each bracket 12 is provided with a vertical driving shaft .14, carried in a. horizontal bracket 12*, at its top, each shaft 14 being provided with an arm 14*, adapted to rotate within the yoke 11 and to reciprocate the latter as shown in Fig. 6 of the drawings.

Each shaft 14 receives its motion from abevel gear 15, meshing with a second bevel gear 16, on the adjacent. end of the drivin shaft 5. The guide stem 11 is provide with a key or spline 11 adapted to'operate in a guide recess in the adjacent hearing head 12. of the bearing bracket 12.

The term vacuum as used herein is a relative term meaning a partial vacuum and the term vacuum is used synonymously with the term suction and such term as used in the appended claims are to be construed and treated accordin l 1 Having thus described one o tlie embodiments of my invention, without having at-v tempted to'set forth all the forms in which it may be made, or all the modes of its use, what I claim and desire to secure by Letters Patent is,

1.- In a washing machine, a cylinder pro vided with reciprocatory pistonheads having valved cups extending toward each other and adapted to be moved toward and from eachother as the cylinder is rotated. 2. In a washing machine, in combination ineaaee with a washing cylinder of open formation including heads provided with hearing elements; of pistons having valved vacuum creating cups movable toward and from each other. longitudinally of said cylinder, and means for reciprocating said pistons.
