Lik e characters -of . reference denote correspon ding parts throughout the figures. Th e frame of the machine includes a plurality of standards or legb 1 having alsters 2 100
[2]2 18,870 at their low'er ends for ease and convenience in nioving the machiiie from place to place, and a series of preferably approximately circular ftames 3, 4 anil 5 superimposed in a spaced relation, one above the other. The :trames 3 and 5 are located at or near the bottom and top of the legs or standards, respectively, as shown, anci may be flat bands whereas the frame 4 is an angular -band or 10 apron located intermediate the frames 3 and 5 and in@imediatc@ly beneath the tub and the latter preferabl ts thereon or has securement thereto. @hme bottom 7 of this tub or container is dished or saucer shaped, -as 15 @shown its lowermost point beinir axially of the tub. It is strengtheiled orbraced cen trally by the _preferably asbestos, sheet or plate 8, next adjacent the outside of the bottom and held in.place by the stiffening plate 20 9 Should there be any vibration of the tub bottom, due to the washing action, the asbestos sheet or plate will act.as a silencer to Both the an open25 a the cena coupling 11 soc to projects in communication therewith to act and from said coupling a drain pi 30 tends to one side of the tiib and hav a re 9- ulating or drain valve 13. The washing element 14, arranged to be suitabl@ supported and opemted within the tub or container 6 may be an agitator or dolly of any desired or approvect construction. Such.agitator or do)ly is arranged for clutch @onnection to the upper end of a shaft passing up through the tub bottom 7. and arran@,ea for pperative connection with' Rc46 tuatmg mechanism located beneath the tub. As shown, the agitator or dolly may have & detachable connection with th4e upper end of the shaft 15 by means of -a suita6le coupling 16. 45 The bearing for the shaft 15 within the tub,, coniprises preferably an u]pstandiniz tu-. bular post or c&,iing 17 disposed througtl an axial opening 18 in the tub bottom 'Lnd through corresponding openmgs irt the 50 plates secured thereto and therebeneath; the greater portion of said post or casing extexiding up mto the tiib, to a point preferably above the water line therein an'd with an extel@sion projecting below the tub, as shown5s Said post or casixig, is -further provided with a fla,nged @)earin@g and clampifig member 19 at or near its lower end, between which and 'd ace of the tub bottom a the upper insi e f suitable gasket or p@cking 20 is inserted, tO 60 form or provide a seal against'leakage such fleinge and gasket or packing being 3rawn firmly down and inat the tub bottom, in 999 @ @ a manner to be expl.ain6d. The gear casing: or housing, comprum 65 preferably elonga and suitably fjhaped rather shallow superimposed sections 20 and 21, adapted to be removably attached to each other by bolts and nuts 22. When united and housin-a the operating gearing, such casino, or housing is disposed below and 70 closely adjacent the bottom of the tub ancl is. arranged radiany or diametrically thereof from a pomt centrary of the tub to a point . outside the periphery thereof, as shown'in Figs. 1 and 2. The outer or extended portion of the@ said casing or housing iLs preferably supported or suspended from the band or a?ron -4, by means of bolts 23, which are s @own passine through spacing sleeves 24. The upper @Bec@tion 21, bf said casin or hous- so ing, at a point where it crosses anlis coincident with the axis and center of the tub, is formed or provided with an overlying shell or casing 25 having an opening 26 therethrough- and the head wall 27 t . hereof, when 86 is secured in posinst the underside e underside of the smg or hous is secured opera- 90 tive p on below the tub, aft 15 pr st or c 95 wall of the section 20 the lowermost end of the tubular post or c ' 9 17 extends. down, preferablv terminatinasgmin the overlying shell or casing 25, stopping 100 short of the upper wall of 'the section 21, as shown. This shell or casing 25 constitutes - a head of materiary less diameter than the length of the Lyear casing and of a length or depth approxi'mating the depth of the gear casing, and is in effect an ad apter, of pref- 105 erably annular or cylindrical-like coin@tour for coupling the gear casing or housing, at the center of the tub, to the lower end portion of the post or casing 17, *hereby the 110 bottom of the tub is clamped or secured between and to the post or casing and adapter, to provide a unitary and rigid like a mbl between theseel-ements; and the casi@ 79 witk operating mechanism therewit,hin, is preferably in the plane of the drive -from the power unit, such as ain: electric motor. Furthermore, placing the shallow gear cas'mg well up under the tub and clamp n r he casing and tub together. )I , includink thte h.ft casing, eliminates the'possibility of out of alignment of the dolly rating shaft, wiu 0 prevent bindin.g . and stayleing of motor and insure easy running and should obviate leakage and attentiozi usuary.required. On the extreme lower end of the shaft 15 is slidablv connected a pinion 2-8 arranged to be mWv@4 into and out of meshing reiation with a segment gear or rack 29 pivotally supported within the -gear casing or housing and to and within the section 20 and has 130
[3]connected thereto a pitman bar 30 in pivotal connection with a gear wheel 31, also j'ouriialed in s'aid gear 'easing or housing and which is in mesh with a driving pinion 32 on a short vertical shaft 33 journaled in the section 20 of the gear casing or housing and a supplemental housing 34 secured to and suspended below the section 20 of said gear casing or housing. On the lower end of said 10 short shaft 33 is secured a preferably crown ; ear wheel 35 witli which meshes an ordinary spur gear wheel 36 on a short transverse shaft 37 to which is secured a purey wheel 38 adapted to be driven from a suitdble source of pow'er and a belt, not shown. The use of a crown gear wheel for the tr&nsmission of the power from the driving shaft to t4e operating shaft 15 will elim@inate the fine adjustments ordinarily -found necessary in 20 machines of this character and obviates the usual thrust @ which is noisy and makes possible @n easy, sm6oth and noiseless running machine. To actuate a wringer mechanism, not shown , there may be provided the ge'ar 25 wheel 39 located within the gear casing or housing and in meshing relation with the gear wheel 31 from wnieli it receives its power and said gear wheel 39 adapted to operate a vertically disposed. shaft 40 from 30 which power may b-- transmitted to the usual wringermechanism, not shown, although its support 41 is shown in Fig. 1. The shaft 40 is pteferably encased in the upstanding sleeve or casing @to, the lower end of which is supported from the exposed end portion of the upper secti6n 21 of the gear casm or housing, which projects out bjyond the tult, and its upper end connected with the support 41.) In this arrangement, a convenient su port and drive between the gear casing or Klousing and gearing therewithin and wrm,aer is providiad, eliminating the unusually Ion connection heretofore made necessary 1 9 as a result doing away with much urmecossary material and thereby reducing the cost of manufacture. The means employed to move the pinion 28 i,ito and out of mesh with the segment gear or rack 29 is a lever arin 42 projecting up at the side of the m'achine and connected with a rod 43, see Fig. 3, which ha-s secured to its inner end the yoke 44 engaging a grooved collar 45 'connected with the ion 28, pin whereby upon the oscillation of the rod 43 th6 pinion may be alt,6mately raised and lowered as shown in dotted and fuR lines in r4@g.. 5, so as to disconnect and conneef said pinion with segment gear or rack 29. Thisarrangement, as will be understood, permits the motor to operate continuously whe'n the machine is in use and yet provides a simple and convenient means for the attendant to connect an-d disconnect the actuating mechanism of the dolly with the source of power'. C3 When the several pa'rts dekribed are -in. 18,870 3 assembled and in operative relati6n, there is carried on the dolly or agitator operative shaft 15 and within the sheii or casmg 25 a flanged collar 46, preferab.ly below the end of the tubular post or casing 17 which acts Eis a water shed to divert any casual water which may trickle down the shaft 15 from entering the,, ear cas@ing or housing, which naturally wouf d be detrimental to an efficient operation of the gearmg journaled and operating to within said gear casing o@r housing. The tub 6, the tubular post or casifig 17 ind th,, fear casing or housing are clamped or firm y @ secured in unitary arrangement, by means of a nut 47 which, as shown in Fig. 2, so is screwed onto the lower end of the tubular post or casing 17 and preferably within the adapter -,hell or casina 25. When so applied, the nut 47 will draw the bearing flange 19 of the post or casing 17 and the head portion 27 So of the adapter toward eacn other, firmly clamping the bottom of the tub therebetween and thereto. Between the nut.47. and the' head wall 27 of the adapter 25 is interposed a gasket or washer 48, of suitable material. .90 The manner of assembling the tub 6, the operating shaft 15, the tubular post or casing 17, the gear casing or housing, and the firmly clamping together of the tub 6, the tubular post or casing 17 and the gear casing or hous- go iug constitute one of the novel and essential fea'gl-ures of the structure bereinabove described. Assuming that the gear casing or housing is supported or suspended in the manner shown, the tub 6 is dropped into posi- 100 tion between the legs or standards so as to rest on the frame 4 in the manner shown and with the plate 9 secured to the bottom of the tub in abutting relation with the head wall 27 of the sheu or casiir;g 25 superimposed on 105 the -,;@-- etion 21 of said gear casing or housing. The tubular post or casing 17 is then placed in position with its extreme lower end inserted through the' axial opening 18 in the - tub and the plates connected ben@ath and 110 thereto'. The lower en'd of said tubular post or casin.- will stop short of the upper wall of the section 21 of the gear casing or hous'ing and within the shell or casin(Y 25, as shown, superimpos ed thereon. The o'perating shaft 115 15 may. be c-onveniently placed at the same time that the tubular post or casing 17 is positioned, with said operating shaft being inserted down and through the upper wall of the section 21 of the gear casing or housing IN and into operative relati'on with the pinion 28 arranged to bave a slidable relation thereon. However,,before, or at the same time that the tubular post or casing 17 and the operating shaft 15 are placed in position, the nut 47 M and the flanged collar 46 are inserted through th!e opening 26 into and withiii the shell or "asin 25 to be in axial alignment with said shaftgand said tubular post or casing so that the flanged collar 46 may have a snug' fit on UO
[4]4 18,870 said shaft and embrace or suir6und the open end of said post adapted to act as a water ing in the upper wall of th6 -section 21 of the shed. te r casing o:r housing in which said shaft as t,, bearing, as best seen in Fig. 2 and with the nut 47 in position to be screwed on to the lower threaded end of the tubular post or casing 17. It has already been explained that between the nut 47 an'd the head wiLlI 27 of the shell or casing 25, a suitable gasket or 10 washer is placed and a suitable gasket or washer placed between the flange 19, on the tubular post or casing'17 and the bottom wall of the tub. This structure s@oals the connection with the tub at this point against leakage and the nut 47 when screwed into position firmly clam s the tubular post or basing 17, the tub 6 anT the gear casing or housing securel to ther. While the upper end of the tugiular'post or casin g 17 is normally 20 above the water line of the tub, should any water work itself down fi,6m the top of the operating shaft 15 and through the tubular )ost or casing 17, it will be diverted at the row,er end of said tubular post or casi r 17 over the flanged collar 46 on to the top ol the 9,,ear casing or housing and be prevented from entering such gear casinlr <)r housing around said operating shaft 15 where it has a beari@& in the upper wall of the section 21 of saia 30 ge'ar casing q)r housing. This condition is not likely to exist but as a safeguard I have rovided this water shed in the form of the iknged collar 46. As will be apparent, power is transmitted 36 from' the shaft 37 through the pinion 36 and c:rown gear 35 to the gear wheel 31 which will iinpart reciprocal movement to the pitman bar 80 and oscillate the rack or segment gear 29 and alternately rotate the dory shaft 15 in 40 opposite dire@tions, when the .pinion 28 is in mesh with said rack. Ile- pinion is arranged to be manually raised and lowered out of and into engagement with said rack through and by means of t;he ?perator's le@e'l 42. 45 What I
