Etten, Waterloo, Iowa Application September 3, 1943, Serial No. 501,180 l 6 Claims. l (Cl. 68-263) My invention relates to clothes wringers ofthe 2 The complete wringer is pivotally- supported on type mounted on power driven domestic clothes an indexing ñange casting 20’ and interposed be washers. This case is a continuation in part of tween the flange 20' and the frame 'III is a pivot my application, Serial No. 388,024, filed April 11, ' plate 2|,to which the frame I0 is pivotally at 1941. 5 tached by the pivot pin 22 on the inner end of The particular object of my invention is to the Wringer. The wringer is normally held in provide a safety pressure release operable upon pivotal movement of the wringer by pressure ap plied 0n any part of the wringer. I am aware that pivotal release mechanisms have been made involving pivotal movement of the wringer in relation to the gear head or such similar ar rangement, but such devices involve separating the gear head from the wringer and supporting the wringeron pivotal links or the like, which introduces complications in structure which I desire to avoid. Another object of my invention is to provide means to pivotally mount a practical, unitary gear head and wringer mechanism by means l20 which will provide a release of roll pressure upon ñxed position by the taper plunger 23, which is held in the mating notch- 24-of the pivot plate 2| by the spring 25>aroun`d the‘plunger rod 26. The plunger rod 26 is slidably mounted in bear ings 21 and 28. By this _structure it will be un derstood that pressure applied on the frames I0 and II will tend to pivot the frame III around the pivot pin 22 and by the tapered notch 24 force the plunger 23 outwardly" against the spring 25, whereupon the rod 26 willbe moved outwardly, pushing the reset lever I4 with it to release the toggle I 5 and with it the top 'frame I I. ' Excess movement of the frame'IIl is prevented by stops 29 and 30 on the pivot plate 2 I," as clear' ly shown in Fig. 2. It will be appreciated that pivotal movement of the complete wringer. the wringer is held inY central position on the I will disclose and describe the device in the pivot plate 2I by the co-action betweenthe 'pivot following description and drawings in which: pin 22 and the taper plunger 23`in the notch 24. Fig. 1 is a front elevation View of the wringer 25 Now referring again to Fig. l, the drive tothe complete in operating position, and gear head is provided by conventional drive shaft Fig. 2 is a top plan view of the Asame wringer 3l rotatably mounted in bearings 32 and 33’in as shown in Fig. 1. the indexing flange casting 20’. The shaft 3| Now referring to the drawings, and at the out is held by the bearings 32 and 33 in the flange set to Fig. 1, I designate the lower frame hous casting 2D’ because it is necessary to provide a' ing, the wringer and gear head complete, con slotted o-pening 34 in the bottom of the frame I0 stituting a single wall thickness part, by the nu frame by reason I0 and of the the relative pivot plate movement 2 I. Thebetween drive shaft( the meral I0, and the upper frame by the numeral II. Conventional wringer rolls I2 and I3 are 3l mounts a conventional spur gear 35 in the mounted in conventional bearings in the lower f gear head which meshes with a companion spur frame as shown. The inner end of the top frame gear 36 on the vvertical shaft 31. The gear 36 is is mounted on the lower frame by a stationary iiXed to the shaft 3l and drives the clutch 36v yby stab clip I3, and the outer end of the upper means of a key 39 on which the clutch is slid frame is mounted on the lowerframe by a pres able. The key 39 holds the loose lower gear 36’ sure reset lever I4 and the toggle lever I5, the 40 and the upper spur gear 40 in operating rela reset lever being pivotally mounted on the upper tionship by co-action with the pin 40’ and the frame II by the pivot I6 and attached to the collar 31’. The clutch 38 is provided with inter toggle lever I5 by the pivot I8, the toggle lever nal gear openings 4I and 42 mating with the in I5 pivoting on the lower frame I0 by the pin I1. ner ends of the respective gears 40 and 36', This is a conventional form of frame attachment f whereby'when the clutch 38 is actuated in one well understood in the art and will not be de direction or another, the internal gears 4I and scribed in further detail except to explain that 42 will 'engage the ends of the respective vgears the toggle lever I5 in closed position is a stable 4D and 36', whereby driving relationship with toggle which is released by moving the reset le the shaft is established and the mating face gear ver I 4 outwardly until the toggle pin I8 is thrown 50 43 may be driven in either direction at the will outwardly beyond the pin I'I when the entire up of the operator by moving the handle 44 to force per frame will be released by the movement of » the eccentric pin 45 either-«upward or down the toggle I5. Roll pressure is provided by a ward to establish driving relationship with conventional spring I9 held in pressure sustain either gear 36’ or 40. This is a conventional ing position by the adjustment screw 20. .55 form of drive gear head which is well understood 2,406,066 in the art, andis 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 attachedV to the _pivot plate 2 i. A release latch 48 is pivotallyf attached to the bracket by the pin 41 and'c'ont'a‘cts‘ an indexing pin '4'9 urged ‘up wardly by the spring 50 as illustrated. The pin 49 is adapted to engage selectively in notches "5i 4 movement between the frame and the plate, said release actuating mechanism including a detent adapted to releasably secure the frame in prede termined position With respect to the plate. 2.
