' PIvoTAL FRAME WRINGER Original Filed April 11, 1941 2 Sheets-Sheet 2 v .Hlm f *J l Mil-ley Patented Apr. 18, 1944 Nicholas L. Etten, Waterloo, Iowa Original application April 11, 19421, Serial No.

388,024. Divided and this application September 3, 1943, Serial No. 501,181 l 3 Claims.

My invention relates to clothes wringers of the type mounted on power driven domestic clothes washers. Y

This is a divisional application of my application Serial No. 388,024 filed April 11,` 1941.

The particular object of the invention is to provide a roll stop mechanism operable to stop the rolls upon pivotal movement of the wringer by -pressure applied on any part of the wringer. I

am aware that mechanisms have been made involving pivotal movement of the wringer in relation to the gear head or such similar arrangement, but such devices involve separating the gear head from the wringer and supporting the wringer on pivotal links or the like, which introduces complications in structure which I desire to avoid.

Another object of my invention is toprovide The complete wringer is pivotally supported on an indexing ilange casting 20 and interposed between the flange 2li' and the frame I0 is a pivot plate 2|, to which the frame I0 is pivotally attached by the pivot pin 22 on the inner end of the wringer. The wringer is normally held in l ilxed position by the taperv plunger 23, which is means to pivotally mount a practical, unitary ,l

gear head and wringer mechanism by means which will provide a stoppage of roll rotation upon pivotal movement of the complete wringer.

I will disclose and describe the device in the following description and drawings in which:

Fig. l is a front elevation view of the wringer complete in operating position, and

Fig. 2 is a top plan view of the same wringer as shown in Fig. 1 with the oil or released position of the wringer indicated in broken dot-dash outline.

Now referring to the drawings, and at the outset to Fig. l, I designate the lower frame housing,

the wringer and gear headcomplete by the nu meral I0, and the upper frame by the numeral I I. Conventional wringer rolls I2 and I3 are mounted in conventional bearings in the lower frame as shown. The inner end of the top frame is mounted on the lower frame by a stationary stab clip I3, and the outer end of the upper frame is mounted on the lowerY frame by a pressure reset lever I4 and the toggle lever I5, the reset lever being pivotally mounted on the upper frame I by the pivot I6 and attached to the toggle lever I5 by the pivot I8, the toggle lever I 5 pivoting on the lower frame IU by the pin I1. This is a conventional form of frame attachment well understood in the art and will not be described in further detail except to explain that the toggle lever I 5 in closed position is a stable toggle which is reA leased by moving the reset lever I4 outwardly until the vtoggle pin I8 is thrown outwardly beyond the pin I'I when the entire upper frame will be released by the movement of the toggle I5. Roll pressureis provided by a conventional spring I3 held in pressure sustaining position by the adjustment screw 20.

held in the mating notch 24 of the pivot plate 2| by the spring 25 around the plunger rod 26. The plunger rod 26 is slidably mounted in bearings 21- and 28. By this structure it will be understood that pressure applied on the frames I0 or I I will tend to pivot the frame I0 around the pivot pin 22 and by the tapered notch 24 force the plunger 23 outwardly against the spring 25', whereupon the'rod 26 will be moved outwardly, pushing the reset lever I4 with it to release the toggle I5 and with it the top frame I I.

Excess movement of the frame I0 is prevented by stops 29 and 30 on the pivot plate 2| as clearly shown in Fig# 2; It will beappreciated that the wringer is held in central position on the pivot plate 2| by the co-action between the pivot pin 22 and the taper plunger 23 in the notch 24.

Now referring again to Fig. 1, the drive to the gear head is provided by conventional drive shaft 3| rotatably mounted inbearings 32 and 33 in the indexing iiange casting 20. The shaft 3l is held by the bearings 32 and 33 in the ange casting 2li' because it is necessary to provide a slotted opening 34 in the bottomof the frame II) by reason of the relative movement between the ,frame I0 and the pivot plate 2 I. The driveshaft 3| mounts a conventional spur gear 35 in the gear head which meshes with a l companion spur gear 36 Von the vertical shaft 31. The gear 36 is fixed to the shaft 31 and .drives the clutch 38 by means oi a key 33 on which the clutch is slidable. 'I'he key 39 holds the loose lower gear 36' and the upper spur gear4|| in operating relationship by co-action with the pin 40' and the collar 31'. The clutch 38 is provided with internal gear openings 4I and 42 mating with the inner ends ot the respective gears 4I!A and 36'. whereby when the clutch 38 is actuated in one direction or another, the internal gears 4| and 42 will engage the ends of the respective gears 40 and 36', whereby driving relationship with the shaft is established and the mating face gear 43 may be driven in either direction at the will of the operator by moving the handle 44 to force the eccentricpln 45 either upward or downward to establish driving relationship with eithery -gear 36' or 40. This is a conventional form of drive gear head which is well understood in the art, and is believed to require no further description.

As is well understood in the art, the lower -frame must be indexed pivotally around the washing machine to provide facilities to'wring from out of the washing machine or out of associated rinse tubs. Such indexing is provided in my device by an indexing mechanism mounted on a bracket 46 attached to the pivot plate 2|. A release latch 48 is pivotally attached to the bracket by the pin 41 and contacts an indexing pin 49 urged upwardly by the spring 50 as illustrated. The pin 49 is adapted to engage selectively in notches in the periphery of the flange 29' and in coacting recess in the plate 2|. By moving the index lever upward the indexing pin 49 is moved down or out of contact with the inthe'drive shaft, a gear housing enclosing the gearing and connected with the wringer frame,

l mounting means for the gear housing and wringer ing engagement between the drive shaft and the dexing notches 5| disposed around the flange of lease the reset lever I4 and the top frame Il, the

entire wringer, including the gear head, -will be lpivotally moved around the pin 22, as shown in broken dot-dash outline in Fig. 2. When such movement occurs in a vbackward direction, the s'pur gear 38 will assume the position shown in dot-dash outline at B. It will be noted that such pivotal movement around pivot point 22 will move the spur gear 38 out of engagement with the spur gear 35, as clearly shown in dot-dash outline B,'and thereupon the drive to the rolls will be interrupted and therefore the rolls will be stopped from power rotation. Similarly, upon reverse movement of the spur gear to the Point F forwardly, the same interruption yof the roll drive occurs, and, therefore, roll stop will be acgearing when the wringer frame is in one position relative to the mounting support and being disengaged from driving engagement therebetween upon lateral swinging movement of said frame relative thereto.

2.' In a wringer, the combination of a wringer frame, a plurality of coacting rolls rotatably mounted in the frame, an upright supporting coiumn having a drive shaft extending therethrough, mounting means for the wringer frame including a support carried by the supporting column, means mounting the wringer frame on said support and having a pivotal connection with said support spaced laterally from the axis of the drive shaft for swinging movement of the wringer frame eccentrically relative to the drive shaft, and gearing connecting the rolls with the drive shaft and including a pair of gears one mounted on the drive shaft and the other fixed relative to the frame in position for intermeshing engagement when the wringer frame is in one position and complished by pivotal movement of the-wringer in either direction.

It will be appreciated that the foree'required to accomplish the pivotal'movement as above described, may be varied by adjusting the tension of the spring 25, or angularity of the plunger 23 and its companion tapered notch 24.

Somel of the structure `disclosed herein is claimed in: application No. 501,180, illed September3,1943. v

Having thus described my invention, I claim:

l. In a wringer, the combination of a wringer frame, a plurality of coacting rolls yrotatably mounted in the frame, a drive shaft, drive gearing for the rolls and operatively connected with the drive s haft, a gear housing enclosing the y gearing and connected with the wringer frame, mounting means for the gear housing and wringer frame including a support and a pivotal connection between said support and the gear housing Vspaced laterally from the axis of the drive shaft for swinging movement of the gear housing and wringer frame eccentrically relative to the drive shaft, said gearing including a pair ofgears interconnecting the drive shaft and the rolls, said pair of gears being mounted in the housing in position for intermeshing engagement when the wringer frame is in one position relative to the mounting support and relatively movable out of intermeshing engagement upon lateral swinging y movement of the frame relative thereto.A
