SNYDER, OF NEWTON, IOWA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE KAYTAG COMIPANY, OF NEWTON, IOWA, A CORPORATION OF DELAWARE. WASI-IING MACHINE. Application filed June 16,1921.---SeT:ial No. 477,888. This invention relates to ivashina machines, an(I includes ,imong other iinprovements such construction that either before or after a period of use a need 'Lor increased i5 capacity can be met b)r merely -@ecuring an auxiliary - washin- m'achine, substantially similar in constructioii to the first iiiachine (except to omit the i-notor and -,vringer), to be colinected to the first n-iachine for opera'L;-on from the mot6r thereof, to enable botb machiiies to work together as a unit. . Among the further object-s of my invention is to provide for the all-t,,tchment of an auxiliary -washing machine to one already in 15 use, in a quick, simple and efficient manner, both machines to be driven from the motor of the first iiaachine by a simple ,ind quickly effected.connection, and both served fr'om a single swinaing -wr.in@,yer; ftirther to pro20 vide novel means fo@ codnecting together such plurality of machiiies; further to generally improve Nvashing machine construetion; fLLrther-to so construct th(@ top portion of the ttib or tubs that spilled water will 25 run back into the tub instead of on the floor; further to form the body portion of the,t-Lib ,of metal, preferably aluminum, and sloped toward the center to permit the easy attachment of a hose, or the like, to effect ready 30 draiiiin(y of the tub without tilting the sam,e; further to provide washino, machiii@ tubs constructed ,vith one or mor@flat sidos at the upper portion; to so arrange the dolly clriving mechanism in the top of the tub as 35 to render the top thereof substantially unobstructed and practically flat; further to provide an improv-ed washing machine tubformed of aluminum, which will not become watersoaked, rust, corrode, dry out, slii,er 40 or split ther to increase the capacity of clothes @'ausrhing machines while occupyino, a small floor space; further to render poss@l-ble the was@ing of only a few pieces with little water, and peri@it removal of t-he 45 water from the tub without tipping the tub; further to provide improved means for automatically throwino, the washer out of gear when ihe lid is @aised, and into gear when the licl is closed; further to provide a 50 washing machine extremely easy t-o operate, and having the main worIKing parts enclosed in oil tighf cases, and to eliminate danger of accidents; further to provide a washing machiiie . especiall.7 adapted for use with a 55 swinging 'Wringer, 4nd a swinging wringer , tliei,efor; furtl-ier to provide a washing inachine constrileted substantially entirely of. inetal, and one that can be easily cleaned, alivays saiiltary, and lio-l-it in weiglit; further to so combine a -wa@shing inacliine and 60 swingin-wringer that the latter can be i-emoved bv nierely lifting it from the franie; further to prodiice a washing machiiie of maximu m simplicity, efficiency and economy; and such further objects', advantacres 65 and capabilities as will latet more fully @ppear. My invention further resides i-,i the combination, construction and arrangement of parts illti:strated in the acc'ompanying dr'Lw- 70 ings, and while a preferred embodirnent i-- sho@in therein, I desire the same to be understood as illustrative only, and not as limiting the scope of my invention. In the drawings:- 75 Fig. 1 is a perspective view of a clothes wa@,;hi no, apparatus ernbodying my invention. Fig. 2 is a plan view of the arrangemen-6 shown in Fig. 1, but omitting the gear casing cap from the lef'u hand machine, ancl 50 with tb.e wringer removed. Fiol-. 3 is a sectional view on line 3-3 of Fig. 2, but sliowing @he -v@ringer in position, @he main parts of the wringer being showii in elevatioii. Fig. 4 is a vertical longitudinalsection oD. a central vertical plane, taken throuo,,h botli tubs of Figs' 1 and 2. Fig. 5 is a, vertical section throulrh one of the tubs on a plane at right angl@s to that De of 'Fig. 4. Fig. 6 is a plan view of the top of one of the tubs, with the cover and a;ssociated parts remove d. Fig. 7 is a fragmentary sectional detail., 95 showina the manner of connection between the two tubs. Fig. 8 is a detailed plan view of tl-ie op.- crating parts beneath the tub. Refe ring to the drawi-ugs, Fig. 3 sho-wo ioa the main or primary washing ii@achine of iiiy ifivention, in which the tub I is mounted upon the legs 2, having adjustable extension.Q 3 at their lower-ends. 'Seciired to and extending between the legs.is platform 4 car- 105 ryino,, any suitable form of motor 5, whicli. is connected by belt 6 (or other sllitable power transmittiiag means) to drive wheel or pulley 7, carried by shaft 8, which shaft as seeii iii F' 8 lias fixed to rot4t@ thc,-re- 110 19-
[2]1,644,959 'tli worm pinion 9, meshing with gear 10, mounted upon the lower end of. vertical shaft 11. Fixed to t-he upper end of shaft 11 is crank arm 12, to which is pivotally con6 nected the connecting rod 13, whicli at its oppo,gite end is pivotally connected to a second crank arm 14, mounted at the lower eiid of vertical shaft 15, which as shown in Fig. 3 is journalled in suitable brackets 16 to and 17. Fixed to the upper end of shaft 15 (see Figs. 2 and 5) is seoinental rack 18, mesbin(r with liorizontal (year 19, which in turn hqs driving engageiia@'nt witli ' on 20, plni fix,ed to t-he upper end of clolly shaft 21, which shaft extends downwai-(fly into the tub and carries the agitatiiig or dolly member 22. As seeii in Fiys. 2 aiid 5, ttie segmental rack 18, gear 19 and p@nion 20, are seated within depressions or casings, by reason of which the top of the tub is substantial flat and free of projections. Sur'y rounding depression 23, within which segmental rack 18 is seated, is an upstanding rib 24, and coveriiig this depression is a cover pla-te 25, formed with ears 26, to which is hin(yed the cover 27 of the tub the cover having any suitible seciiring means 28, for locking same in closed position. It will also be seen in Fiz. 5 that the cover 27 is formed with an eloii@@ated depression 28', receivin(v ic,rear 19 and - Dmion 20, an(I which depressio@ is covered bi plate 29, suitably secured by bolts, or the like, to cover 27. This arrangement is such that the dolly- driving meang at the top of the tub are mounted in the oil tight casil'i ' cs in a stibstanially flat manner. Formed iia'@'c'over plate 29, is an an(yiilar an(I sliglitly upstan(lin- portion 30, ivliieh contacts with cap 31, to support the c-over in Open position. Extending upwardly in vertical aligiiinent with shaft 11 (see Fig. 3) is shaft 32, havina a clutch coiinect-ion 33, at its uppei end to receive sleeve 34 of shaft 35, wliieh through the medium of bevelled gears 36, 37 and 38. drives the rolls of wringer 40. Longituoi-nally slidable on shaft 35, between gears 36 and 37 is clutch member 39, provided at its opposite ends witli clutch surfaces to respectively en(,afye cooperat.id(y I C, n clutch surfaces on the inner faces of bev(@ gears 36 and 37, wbereby when clutch 39 is moved lon@itudinally of sliaft 35, to which it is spline'd (which ihovement is effected by the handle 41), the -wrin(yer rolls, a,s will be readily understood, nia@ be rotated in one direction, or the otlier. Downwardly extending from gear casing 42 of the wringer is the tubular portion 43, rotatable on c6l6( uMn 44, surrounding shaft 32, by virtue of which the wrinzer,may readily be swung into any desirechorizontal position and secur, d in such position by entry of rod 45 into the appropriate not@h 46 of odtwardly e:ktending collar 47, seeqred to cq!um, n 44; aiid iipon which collar is seated the lower end of sleeve 43. As- will be readily noted, this construction is such as to en@ble the wrin(yer to be readily removed from its support by merely raising tlie, same vertically 0 from column .44, and when desired replaeed through reverse operatiolis. As will be seen in Fi-. 61 the two sides 48 and 49 of the top oY the ttib adjace'nt which the wrin(yer will be swung in tivo of its posiiions are downwardly and inwardly incliiied to return any water coming in contact therewith from the wrin(yer iiito the ttib. The greater part of the re@naining sides, bounding the opening in the tub top ar6 flat, 80 as shown at 50 and 51, and the entire top qf the tub is substantially surrounded by.-an upstanding flange 52, to assist in returning any spilled water back into the tub, and prevent the same from going on to the floor. 85 It is also to be noted that the inner edoe of el the botttom of depression 23 is dowilwardl-land in-wardly inclined, as shown at 54, in Figs. 5 and 6, which constrtiction further assists in returnino, spilled water into the tub. 00 The under face of the marginal portion of the tub lid 27 is formed with the depending flange 55, which a-s seen in Fig. 5 fi.ts ingide of upstanding rib or flange 52 to e:ffect a substantially water ti(yht joint.. 95 As seen in Fig. E, the body portion of the tub is slo-ped inwardly and dow-n-,",ardly as showii at 56 'and 57, and is provided at its central and lowermost portion with an opening 58, to which 'is suitably and in a water 100 tight manner coiinected the outlet. member 5q, to wbicli member in turn is secured a di-@in bose, or the like, 60, which when not in drainin(r position is at its free eild placed bet-ween tl@e projecting fingers 61 at the top 105 of the tub to be held therein while the tub is in opetation, which as will be noted positions the outlet end of the drain hose above thp, water level, and prevents the passage of any water through the drain bose. This con- 110 struction if desired may take the place of a valve, ihus rendering the di,ain hose always ready for use by simply detaebing it from supporting fingers 61, and t]-ic end of the hose moved to a sewer rating, bucket, O'@r @ 9 the like. As seen in Fig. 5, the top portion t of the tub is secuied by rivet.s, bolts, or the like, 62, to the bottom portion of the tub. From Fig. 2, it will be noted that the drain hose supporting fingers 61 are formed as 121) part of cover plate 25, ai)d extend a slight distance beyond the side of the tiib. It will be understood that the ei-id of drain liose 60, will be provided with suitable extensions 63 an-d 64, - to insure that'the end of the hose will be retained in position in flngers 61, until fts removal is desired. The upper portion of the sides of tub 1 are substantially straight, and the side viewed iii Fig. 3 is of special formation to
[3]1,644,959 8 ,afforci secure contict tliere-%Yith of an adjacelit tub to be secured to the first tub. This is eIT-ected by providing this side of the toP portion ivith tipstanding and narrower porg tions 65, and tl-le loiver or main portion o,f the tub body with outstanding ribs 66, ivhose faces are i-n the same plane with the faces Of portion 65. A similar construction is fotind lo in the @luxiliary @tub or extension to be- atiached to. the first described tub, wliieh connection is ei-Tected by the bolts, or the like, 671 extendiiig tbrough ribs 66. By this trrangement the tub of the auxiliary machine@ may b-, qtiieli:ly and sectirely fastened along 115 side of the first tub, and operated from the motor of the first machine in a manner now to be described. Assuming that the tiser has operated the tub above first described, and fincls a need for (yreater capacity, he can se2( cure a second machinp- -without the motor or wringer, witli the two legs on the side adjacent the first machine omitted (or such two legs may be removed) and quiel-,ly secure the 2.1 second machine to the first niachin-e as described above. To effect operation of the second macliine from the motor of the first machine, ali that is necessary is to connect the free end TO of the coup' lirig member connectliti ing r6d 13' of the second macliine pivotally at 71, to connecting rod 13 of the first machine, -wliieh will result in the, movement of connectin,, rocl 13 being transmitted through connectin(r rod 13' to crank 14' of the second zn niachine, and through t vertical shaft 15' 35 similar to sliaft 15 of the first machine, the rotary oscillatory motion of which will be transinitted to the dolly of the second machine, througli mechanism similar to that already described above. With this arrange40 ment, only a single motor (that of the first n-iaeliine) is necessary, and both tubs will be seri,ed by the -wrinoer of the first machine. If desired, additional bracing members 76 inay be appliecl to the second machine. If 4v desii-ed, an additional brace member 72 may be securqd at one end by a suitable bolt, or the like, 73, to the casing 74 of crank 12 and ,it its other end by 'a bolt, or the like, 75, to tl-ie bracket 16 of thp, seco-nd tub, t,lus giving additional stiffening means between th@ two tubs, It is also to be noted that when' two machines are secured to operate together, the casters of the inside legs of the first m,,Lchine may be omitted and the, adjustable exr) tension 3 may also either be omitted or adjusted either into or out of contact with the floor, as desired. Adjustment of extension 3 iiito Arm contact with the floor, will furnisli additional siipport for the central portions of C, 0 the combiiied machines, if desired. While I have shown 9, conventional type of motor, it is to bs understood that any suitable source of motive po-wer may be used, without departinly from the spirit of my invent-ion. 65 Ref@'rring to Fig. 3, it is to be noted that ei-aiik 12 at the, upper end of shaft 11 is of tli.e following composite construction: This crai-ik is formed of two cranks, the one craiik arm a of -wliieh is fixed to the upper end of sliaf t I 1, while ihe other crank arm b thereof i'O is fixed to the lower end of shaft 32. Crank arin ct carries the upstanding pin c for rotat:ably receiving the ei-id of conliecting rod 13. Pin c is forined at its upper end with a depi-ession d for receiv ing projection e, de- '5 pencling from erink arm b. These interfittin g parts causing the.@e tivo crank arms to iotate together, tnd at the s,,tiiie time providin g a flexible connection betweeli shaft,3 11 aiid 32, which perinits ready removal 6f 8,3 thes e pai-ts fi-om casing '(4, as well as assembling of the i-espective parts. It, is also of importance to iiote (see, Figs. 2 aiid 8) that tli-e craiik arms 14 aiid 14 ' 85 froin which the respective dollies of the two mac hines are driven, are so positioiied relative to eacli other, and connecting rod 13' so arra nged that when the dolly driven from the crank ,trm 14 is passing tlirough its dead S)O cent ei- the dolly driven from crank arm 14' will b'e rotating at maximum speed. @iaving now described my iiivent@@on, I
