To all lwhom t 'may concern:

Be it known that I, ALvA J. Frsrmma citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines Having Agitating Mechanism, of which the followwhich the agitation takes place a bearing sleeve for the operating rod or shaft of the agitating mechanism, such sleeveextending l above the line of liquid, thereby dispensing with` the employment of a stuffing box o1" the like.

Another principal object of my invention is to provide for the arrangement and' support of all of the operating mechanism below the. receptacle or vat and substantially within the lines of the supporting legs thereof, thereby leaving the top and sides of the receptacle free of such mechanism.

My invention relates to other novel and advantageous features of construction and Inode of o eration .which-will be apparent from the escription hereinafter given.

For a definite disclosure of my invention I have shown it embodied in a Washing machine but it will be understood that in its broader aspect it is not limited thereto and that I contemplate using the same wherever applicable.

In the drawings Figure 1 is a side elevation of a washin machine with a wringer attached illustrating one embodiment of my invention; Fig. 2 is aside elevation of the same machine taken at an angle of 90 with respect to the elevation of Fig. 1; Fig. 3 a section lon the line 3 3 of Fig. 2 but on a somewhat larger scale; Fig. 4 a sectional plan on the line 4 4 of Fig. '3; Fig. 5 a

4detail of a portion of the operating mecha- Y nism; Fig. 6 a section on the line 6 6 -of Fig.- 3; Fig. 7 a section on the line 7 7 of Fig. 4' and Fig. 8 a sectional elevation of the parts shown in Fig. 7

' character.v f

Referring to the particular embodiment of my invention shown in the drawings, the

washing receptacle or vat 1, which may bev of any suitable shape and dimensions, isy

supported some distance above the floor by means of the legs 2, preferably provided with casters 3. This receptacle is open at lts top but normally closed by means of a lid or cover 4. Within the receptacle is.

located asuitable agitating device which is here shown asa dolly bar 5 having a series of depending portions or lingers 5a and adapted to be agitated by oscillation imparted by the agitating mechanism hereinafter ldescribed. This bary is mounted to sllde u on a bearing sleeve 5b, which is itself secure to an upright 'operating shaft, or rod, 6in a Suitable manner as by means of pin 6a, which fits over and downwardly upon an elongated bearing sleeve 7. This sleeve is of the peculiar formation clearly illustrated in Fig, `3, wherein ,it is seen that it isprovided intermediate its length with afoot portion or flange-7a secured in suitable manl 'water overflowing the top 'of the sleeve and flowing downwardly between it and` the v operating rod or shaft 6.v As a result of this construction 'it is entirely unnecessary to employ a stuffing box, which is objectionable and unsatisfactory in machines of this n The mechanism for operating theagitat- Ing device through the medium ofthe vertical rod 6 is compactly constructed andarranged and located in the open space below the receptacle and within the confines of the supporting legs of such receptacle. More;

over all of said Vmechanism is supported upon a single base plate or .bed 10 which is itself screwed to the legs 2 of the 'ma'- chine. As shown, I prefer to employ as the .prime mover an electric motor 11 mountedv on said base although it will be understood that any other source of power may be eml 45 also a gear wheel 29.

sprocket wheel is provided with a suitable ployed. The motor is operatively connected by means of a belt 12 with a large pulley 13 secured to a shaft 14 which is mounted in suitable bearings 15 on the base plate. This shaftisprovided at one end with a pinion 16 which in`turn meshes with a large gear 17 secured to a shaft. 18 mounted in suitable bearings -19 on the base plate. The gear wheel'17 is providedwith a crank 20 connected by means of a link or connecting rod 21 with a-horizontal reciprocating rack bar 22. This bar is adapted to slide in the two slotted posts or standards 23 and 24, the former of which has provision for vertical adjustment in the manner .indicated in detail in Figs. 7 and 8 wherein it is seen that the post is provided with the two antifriction rollers 25 bearing upon the top and 'bottom respectively of the rack bar and adapted to' be adjusted vertically in the slot v23a and be clamped in adjusted position by -means of the nut a. The outer end of the bar 22 is pivotally .connected to the rod 21 while its inner end is formed as a rack, as

25 shown at 22a in Fig. 4.l This rack meshes with a horizontal pinion 26 which s secured to the vertical operatingfrod or shaft 6. The result ofthese operating connections is to transform the rotary movement of the electric motor to an oscillating movement of the rod or shaft 6. The rotary movement is imparted by the operating connections hereinbefore described to the gear wheel 17,y

f whose crank imparts a reciprocating movement tothe bar 22, which latter movement is imparted to the pinion 26 to provide the oscillating movement. of the rod 6.

Upon the same plate I provide operating connections including a reversing mechanism for driving va' wringer 27 which is here shownfas securedv to the top of the receptacle or vat. As clearly shown 1n Fig. 4, theshaft. 18 is extended to the right and carries loosely mounted thereon a sprocketwheel '28v and The hub of. the

number of clutch lugs 28 and likewise the hub of the gear wheel 29 is provided with similar lugs 29, such lugs facin each other. Splined to the shaft 18 at apomt between the sprocket wheel and gear wheel is a laterally movable clutch 30 which has clutch lugs 30EL on its opposite sides adapted to engage the'lugs 28a and 29a accordingly'as it may be shifted from its neutral position shown in Fig. 4 to an engaging position in one direction onthe other. Assuming that the clutches move to the left (Fig. 4) and the clutch lugs 28'a and 30a are thereby engaged, the sprocket wheel 28 is rotated" and such movement is transmitted by means of a sprocket chain 31 to a. s rocket wheel 32 which is mounted on a sha 33 j ournaled in a bearing 34 on the base plate. This latter y alinement.

shaft carries at its outer end a sprocket.

wheel 35 which is operatively connected'by Ameans 0f the sprocket chain 36 with a sprocket Wheely 37 on the wringer. vThe wringervwill now be operated in a certain direction when the clutch is thus engaged 30 is moved to the right (Fig. 4) and the `with the lugs 28a.v If, however, the clutch4 lugs 29a and 30a thereby engaged the pinion 29 will be rotated thereby, rotating a similar pinion 38 which is secured upon the shaft 33. When the clutch is thus engaged the shaft 33 and consequently the wringen will be operated in the reverse direction, 1t being understood that at this time the sprocket wheel 28wi1l rotate idly just as did the pinion`29, when the sprocket wheel 28 was being positively driven. The reversing clutch may have any desired shifting mechanism such as the vertical rod 39 arranged to be oscillated bythe handle 39a and operatively connected with the link 40 which is itself connected directly with the clutch shifter 41.

By the use of my invention I am able to provide a machine of 'the classdescribed which yis novel and elcient and which is moreover comparatively simple in construction and not liable to get out of order. Moreover the machine is compactly built and self-contained and arranged with the operating mechanism occupying space which would otherwise be useless and leaving the top of the machine free from operating mechanism except the wringer when the same is used in connection-with a, washing machine. Furthermore I dispense with all stufing boxes and the like by provision of v the sleeve which not only affords a long bearing for the upper end of the operating rod 6 but also prevents the water from leaking past such shaft. In addition to thisbearing in the sleeve the lower end of the shaft is provided with a substantial and comparatively long bearing Fig. 3. The shaft is thereby'held in perfect plate being arranged below and Within the' lines of the receptacle. t

2. In amachi'ne of the class described, the combination, wlth a receptacle and its supporting legs, of an agitating device within the receptacle, an oscillating shaft extending vertically through the bottom of the1 recep- 10 rising upwardly rfrom the base plate as clearly indicated in tacle and operatively connected with said supported thereby constituting a unit which is bodily attachable to and detachable from said legs.
