Patented Oct. 14, 1952 I Eldred-OJ-Mort'on, Mansfield, Ohio, assignor to 1 v Westinghouse Electri HAVINGA RESILI- i J npz'rm'snrron'rnn TUB STRUCTURE Y c Corporation, East Pittse burgh, Pa... ai'corporation of Pennsylvania Application September 3, 1948,'Serial No. 47,639" N This invention relates to a machine'forwashin clothes of the type having an outer casing structure, a resiliently supported washing unit ar-' ranged therein and a flexible wall structure connecting the casing and resiliently supported unit for providing communication between access openings formed in the casing and-insaid unit; which flexible wall permits relative movement between the unit and casing and prevents the spilling of water from the unit. 1

An object of the inventionis to provide an improved washing machine'of. the type set forth.

A further object of the invention is to provide an improved flexible wall structure which may readily be connected to the casing and washing unit of a machine of the type set forth.

These and other objects are effected b the Q invention as will beapparent from the following description and ,claims taken in connection with the accompanying drawings, forming a part of this'application, in which:

Fig. 1 is a vertical section taken through the casing .of one form of washing machine constructed and arranged in accordance with my invention, portions of themachinebeing shown in elevation; v a

Fig. 2 is a front elevatioirof-the upper portion of the machine shown 1l l'Fig;1-;'

Fig. 3 is an enlarged section of a flexible wall shown in Fig. 1; and

Fig. 4 is a view of a detail employed tojsecure the flexible wall to the washing unit shown in Figs. 1 and 2. l

Reference will now be had to the drawings, wherein I have elected to disclose my invention applied to a washing machinegenerally of the type disclosed .in the patentof Frank Breckenridge, 2,296,25'l, granted September 22, 1942. This type of machine includes an outer casing structure having a front wall H, the upper portion of a rea m (01. 220-15) Arranged within the casing 10 is a clothes washingand centrifuging unit, genera1ly-indicated at 2| and including a tub structure 22 having a front wall 23 which is spaced from the .wall portion l2 of the casing; The wall 23-iszprovidedwith a relatively large I access opening 24' alignedwith the access opening IS in the casing; Arranged within the tub 22 is a generally frusto"-. conical basket structure 25' having a side wall 26 substantially perforate throughout its extent, a number of the perforations being indicated at 2l'.- The front end of the basket 26 1s also providedwith a relatively large access opening 28 alignedwith the access opening 24' of the 'tubu- The basket '25 also prov'idedwith a number of -con'ventional vanes, two o-f-which are shown at-29iifor= agitatingthe fabrics contained within the has-- ket during the washing operation' t The basket 25 is rotatable about its'iobliqu'e. axis by an electric motor 31 carried by a'suitable' bracket structure 32 from the tub 22; i. The motor v 3| is effective to rotatethe basketat a relatively low speed-of, for example, 50 R. -'P. M;"-==during washin'g periods, and at a relatively hig l'i speed of, for example, 500 R i-P'. M; during centrifugingperiods. As shown,-'the motor 3l -isconnected by 'a'belt 33'to asheave 34 s'ecured'to adriving shaft 36 of a. conventional, adjustable twospeedtransmission indicated" generally at3l: "l h'e lat ter is provided with a driven shaft 38 whiclris fixed a's'shown at 39 to the basket 26 forthe ro tation thereof." As adjustable two-spaced m'e'chanismsof thetype 'sho'wnat 3-1 are well under:

stood in the art: and, sinc'e the transmissionrier se forms-no-part of" the presentinvention, fu'rther description thereof is deemed unnecessary.

a .source of. supply through a. conduit 4t having.

portion l2 of which is inclined upwardly and rearwardly of the casing Ill; The inclined portion [2 of the front wall is provided with a relatively large access opening l3 which is closed by a door structure l4 shown inits closed position in Fig. 1, and in its open position in Fig. 2. The door may include a rigid frame 15 having a transparent window 18 mounted therein which 1 frame [5 is secured to brackets H. The latter are pivoted, as shown at I8, to the casing so that the door 14 may be moved from the closed position, as shown in Fig. 1, to a generally horizontal, open position, as shown in Fig. 2. A suitable latch structure, generally indicated at I9, is employed for retaining the door in its closed position.
