` 18 Claims.
This invention relates to gearing for washing machines.
The invention has special reference to gearing adapted to impart an oscillatory motion to an agitator for washing machines, coincidently with the actuation of means for operating a Wringer.
The invention is directed to gearing mechanism, including a member driven eccentrically with respect to a driving means therefor, a rockable member and a connecting member between said eccentrically actuated means and said rockable member.
The invention includes means for optionally engaging or disengaging the gear driving means for an agitator including details of structure relating thereto. The invention includes an integrated housing means for the gear mechanism and has a container for lubricant therefor.
Referring to the drawings,-
Fig. 1 is a cross-sectional view of a washing machine structure, including my gear mechanism, taken substantially on a line through the diametrical center of the tub and housing members for the wringer driving shaft;
Fig. 2 is a longitudinal sectional view on the line 2 2 of Fig. 1;
Fig. 3 is a longitudinal sectional view on the line 3 3 of Fig. 2;
Fig. 4 is a cross-sectional view on the line 4 4 30 of Fig. 1;
Fig. 5 is a cross-sectional view on the line 5 5 of Fig. 1;
Fig. 6 is a detail Vview, showing the upper end of an agitator drive shaft.
In the drawings, 10 refers to leg members of a frame, there being three of such leg members; l1 is a circular bank attached, as at 12, to two of the leg members and to a gear housing member, as at 13. 14 is a tub and l5 is a detachable lid 40 or cover for the tub.
Referring to structure within the tub, 16 is a shaft extending upwardly through the bottom thereof, the same being marginally rounded at its upper end, as at 17, and provided with a` 5 plurality of elongated vertical slots 18. 19 is a wringer shaft. 20 is a gear fixed to the lower end of shaft 16. 21 is a worm wheel fixed to the lower end portion of shaft 19.
Referring particularly to gear mechanism for operating shafts 16 and 19 and housings and supports therefor, 22 is the main transverse -portion of a casing, and 23 a minor portion thereof, said casings being relatively angularly fashioned in cross section and connected together by means of bolts, as 24, to form a complete housing. 25 is an integral portion of said main housing and 26 is a detachable member thereof located beneath the main housing. 'I'heunit housing is connected at one end by means of branch bracket members 27, divergent from the minor housing'member 23 and connected with relatively spaced leg members 10, the opposite end of said housing being supported in connection with one of the leg members, as at 28. 29 is a worm gear fixed to shaft 30 and adapted to co-operate with worm wheel 21. 31 is a housing sleeve for shaft 30 integrally related to detachable housing member 26. 32 is a V-band wheel fixed to shaft 30 and is adapted to be driven from belt 33 from wheel member 34 on a shaft of motor 35. Referring particularly to gear mechanism for l driving gear member 20, 36 is a gear segment centered upon pivot member 37, the latter being xed l in connection with the main transverse casing portion 22. 38 is a driven eccentric disk member, the same being fixed to wringer shaft 19 at a point spaced from the center of said eccentric member and adjacent to the periphery thereof. 39 is an eccentric band centered upon eccentric disk member 38, and adapted to be driven by the latter. and 40 is a rod or pitman integrally related to eccentric bank 39 `at one end and its opposing end being pivotally connected as at 41 with gear lsegment, 36. To the upper marginal face portion of eccentric bank 39 and adjacent and ra- ,dially disposed with respect to Wringer shaft 19,
are provided clutch lugs 42.adapted to be engaged by a clutch member on the wringer shaft 19 (see Figs. 2 and 4).
43 is a collar splined on shaft-19 for longitudinal adjustment thereof, said collar being circumferentially grooved and also being provided with lug` members 44 at its lower end projecting horizontally of said shaft 19 and adapted to engage, at 95 option, with lug members 42 on eccentric band member 39. 45 is a fui-cated clutch shifting member engageable with the groove in collar 43. 46 is a plunger member supported for longitudinal movement in a perforation, as 47, in vertical housing-member 25. 48 is a shiftmember pivoted to plunger 46 as at 4'9, the latter being so seated in connection with a horizontally disposed face portion of the vertical housing that when said shift member is turned downwardly it would operate to lower plunger member 46 to cause collar memberv 43 to be depressed to effect clutch engagement of the latter with eccentric band 39. whereby driving connection will be established between wringer Shaft 19 and the gear driving connection there- 110 l l in Fig. 1, operate to effect tension to maintain said shift member in vertical position and hold the clutch parts-in relative relief of each other.
agitator and means for supporting andoperating the same, 51 is a sleeve extending through an opening in the bottom of the tub and having threaded connection with a block member 52 forming a part of the gear housing, the said sleeve being fashioned at its lower end to form a bearing for shaft 16 and'provided with a spacing member 53 at its upper end intermediate its interior surface and shaft 16 which also serves as a bearing for the upper end of shaft 16. 54 is an agitator comprising a disk-like portion at its lower extremity and extending upwardly in the form of a sleeve, the said sleeve portion being provided with an axially disposed opening having a plurality of outstanding ribs adapted to engage elongated grooved portions 18 at the upper end of shaft 16. The agitator is also provided with a plurality of relatively spaced agitator blades as 55.
56 constitutes a housing for the wringer shaft, but inasmuch as the means for housing the wringer shaft constitutes no part of the present invention, no detail description will be given either of it or of the wringer and its driving connection.
A thrust bearing is provided for shaft 30 which consists in the provision of a collar/57 interposed between worm 29 and offset or shoulder portions 58 on sleeve 31. This thrust member takes the place of the ordinary ball bearing thrust member.
Also,.a salvage means is provided for any oil that may escape between the frictional bearing contacts respectively at the ends of bearing collar 57 into the supporting opening in sleeve 31 for shaft 30, such salvage means consisting in the provision of special threads 59 on said shaft, said threads being so pitched with respect to a line vertical to said shaft, that in the proper direction of turning of said shaft, such escaped oil will be fed towards worm wheel 29 for return to the general gear housing units, thus salvaging said oil against outward flow towards and to the forward opening in sleeve 3l.
The housing unit herein described as including the major horizontally disposed housing portion 22, the minor housing member 23, the vertically disposed housing portion 25 and the detachable housing member 26, is designed, when assembled in unit form, to form a receptacle for oil, grease or like lubricant in quantity sufficient with respect to the capacity of the unit and the location of the gear operating members therein enclosed, to serve for complete lubrication of the bearings of said gear members to afford at least theoretically permanently continued lubrication thereof.
In operation, the parts of the device having been assembled in the relation herein shown and \described wringer shaft 19 is driven permanently in a single direction and agitator shaft 16 alternately in reverse directions. In carrying out this result, a motor 35 is employed to drive belt 33, which serves to turn belt wheel 32. Shaft 30 is driven from belt wheel 32 and through worm gear 29 worm wheel 2l is driven, which serves to actuate wringer shaftv 19 in a constant direction. Upon effecting a. clutch relation between clutch collar 43 and eccentric disk member 38, Pitman nection of the eccentric band thereon with eccentric disk 38, and due to the pivotal connection of said pitman with segment gear 36, which cooperates with gear 20 on shaft 16, the latter will be caused to be reciprocated alternately reverseltyr to cause reciprocation of the agitator. Clutching and unclutching relation is established between clutch collar 43 and eccentric disk 38 by a simple Referring particularly to the washing machine` shift of collar 43 through manipulation of shift member 48 to or from a vertical position, as and according to the desire of the operator to effect driving connection to the agitator or discontinue the same.
Actuation of wringer shaft 19 will afford a means for driving the wringer through proper means (not shown) for optionally establishing or discontinuing driving connection with the latter.
Connected relation between the agitator and reciprocatingdrive shaft 16 therefor is established by merely sleeving the agitator upon its support. In eifecting the sleeved relation of the agitator with respect to the shaft and its support, the agitator is merely placed in contact with the upper end ofshaft 16 and because of the relative fashioning of the upper end of said shaft and the vertical opening in the upper end of the agitator sleeve and the arcuate fashioning of the periphery of the upper end of said shaft, movement of the shaft will readily find relative cooperating engaging slots and ribs, whereby said agitator will automatically find for itself the proper and necessary driving connection, whereupon it will seat itself with respect to said shaft to establish such proper relative driving connection.
