Application med February 6,

The object of my invention is to produce a clothes wringer structure of the type wheresociated with and dissociated from the lower roll by a lateral swinging movement of a supplemental upper frame bar which carries a spring abutted upper roll and forms a finish the construction being such that dissociation of the rolls, in case of accident, may be accomplished very quickly by the exertion of a comparatively small force transversely in a direction either from or toward the" operator from either side of the wringer.

The accompanying drawings illustrate various forms of my improved structure.

Serial No. 518,838.

conveniently formed of sheet metal if de-= sired, having a trough-like middle portion 11 within which the lower roll 12 is situated. At each end the base is provided with an end plate 13 medially vertically slotted at 14: to permit the shaft 15 of the lower roll to descend to a proper position. Outside of each end plate 13 is a boxing 16 open at its top and adapted to receive a bearing block 17 for the lower shaft, the outer plate of one of said boxing's being perforated at 18 to ermit the projection of one end of shaft 15 lower roll shaft.

Thus far the structures in the three forms shown in the drawings are substantially identical, differing perhaps in "minor dimensions.

Referring now to Figs. 1 to 3. Vertically removably mounted in each boxing 16 is an anchor fitting 19 having depending legs 19 and an intermediate arc-shaped portion 20,

the legs fitting within boxing 16 and held in place inany suitable .manner suchfor instance as by readily removable screws 21. Rising vertically from the middle of the are 20 is an anchor finger 22 carrying at its upper end, on its opposite sides, anchor rollers 28 journaled on an axis parallel with the axis of the lower roll 12.

lhe upper roll25 is carried by a swinging supplemental frame comprising a main bar 26 having depending legs 27, 27, each of which is vertically pocketed, as indicated at 28, to receive the shaft 25 to receive the upper roll bearing blocks 29, 29, which may be conveniently half blocks, and the pressure springs 30. The bearing blocks 29, pressure springs 30 and upper roll shaft 25' are limited in downward movement by couplings 31, 31, each of which is removby any suitable means such as screws 32. Each coupling 31 is provided with two depending plates 33, 33, separated axially of the upper roll by an amount slightly greater than the total axial dimension of the anchor elements 22-23, and each plate 33 is provided at its lower edge with an inwardly-proof the upper roll and permit vertical movement thereofand semi-cylindrical shown in jectin cam flange 34 so arranged as to be forcib e beneath one of the rollers 23.

he swinging supplemental frame may, in the main, be conveniently formed of sheet metal and, to give a finished appearance and hide the coupling between the base and supplemental frame, the end elements of the supplemental frame ma be provided with de pending 1i s 35 and e boxings 16 may have arc-shape lips 36. v

a 11 order to form a definite fulcrum for the swinging supplemental frame, irrespective of the position of the upper roll in said frame, each coupling 31, on its inner face adjacent the end of the up er roll, is provided with a ange 31?, the outer diameter of which is substantially equal to the width of slot 14. v

this construction the swinging frame is tilted to an angle of about forty-five degrees and the upper roll is lowered down toward the lower roll with flanges 31' in slots 14 until the lower ends of the tilted cam flanges 34 are in a position to pass under the anchor rollers 23. Thereupon the sup lemental upper. frame, fulcruming upon auges 31 in slots14, may be swung to a medial vertical position, thus forcing the cam flanges 34 under the rollers 23, thereby-forcing the upper roll down firmly upon the lower roll and compressing the springs 30 to tent, the parts being then in the position ig. 1, in which position the supplemental frame, being firmly anchored to the base, is in position to'aflord a proper abutment to the springs 30 to coact with the u per roll when material is forced between the up er and lower rolls.

11 case of accident the upper roll may be immediately released from the lower roll by striking the upper bar 26 in a direction at right angles to the roll plane and swinging it to the position shown in Fig. 3. I

In order to insure holding of the supplemental frame in its medial .position against anything but intentional displacement, the flanges 34 may, at their middles, be provided with a slight depression 34 to receive the rollers 23, these depressions not being sufiiment to add too greatly to resistance of the anchorage to dissociation by transverse force can applied to the upper bar 26.

Referring now to Figs. 6 to 10. As inthe form shownin Figs. 1 to 5 the supplemental swinging frame comprises the upper bar 26, depending legs 27 upper roll 25, upper roll bearing blocks 29 and springs 30, separation of the upper roll from legs 27' being normally prevented by removable cross pins 40.

paced from the outer face of each leg 27' is a plate 41 which, near its lower edge, is jacent leg 27 by two of which laterally-spaced pins 42, 42, the axes are parallel with the roll axes.

,nion pin 55 -"a slot 56 in is a vertical cam upper end with an inverted Y cam slot comprising the stem portion 44, open at its upper end, and the'connected depending arms '45, 45 adapted to receive the cam pins 42, 42. he Y-shaped cam slot may, it will be readily understood, be of various shapes, the construction shown .in' probably preferable forthe reason that these cam slots at the middles of the branches 45 are provided with slight depressions .45 to afford a slight anchorage'for the pins 42 against accidental swinging displacement of the supplemental frame from its normal medial operating position.

cam slot of the form shown in Fig. 11

will be satisfactory but perhaps not quite so stable 8. structure as tion shown in Figs. 7 and 8.

In this construction the parts are assem- Figs. 7 and 8 being.

the cam slot construplate 43 provided at its bled by tilting the supplemental frame to a position in the neighborhood of ninety degrees from the pins 42 in the stems 44 of the Y cam slots, whereupon each lowermost pin will move laterally into one pin may then be swung downwardly into the other arm of the Y until the supplemental frame is brought to a medial vertical posi-- tion, at which time the upper roll is forced the deslred exd own upon the lower roll. In the form shown in Figs. 7 and 8, when the swinging supplemental frame has been brought to .medial position, the pins 42, 42 will lie in the shallow notches 45 in thearms of the Y cam slots, thereby affording a stable anchorage for the supplemental frame which, however, ma be readily displaced, to relieve the upper rol from ressure relationship with the lower roll, by isplacement of the upper bar of the supplemental frame to one side or the other of itsmedial position.

Turning now to Figs. '12 to 1.4. Each boxing 16 is flanked, by an upwardly-extending anchor plate 50 provided at its upper end with an inturned flange 51 conveniently sulfiarm of the Y and the upper vertical and entering the ciently "stiffened by a down-turned edge 52,

being preferably provided a depression 53 in its under construction each depending swinging supplemental frame each flange medially with In this leg 27 of the is provided ,onits outer face with a plate 54 into which is detachably secured a trunpassed into said plate through plate 50. Each plate 54, at its upper end, is provided with a roller 57 adapted to take under the adjacent flange 51.

In this construction, when the swinging frameis swung to one side or the other as indicated in Fig. 9, there is no pressure relationship between the upper'and lower rolls. Pressure relationship is established by swinging the supplemental frame to its medialvertical position, thus-bringing rollers 57 under flanges 51, the swinging frame fulcruming upon pins 55 in slots 56.

- In the construction shown in Figs 12 to 14 the swinging supplemental frame is not normally separable from the base, as in the constructions shown in Figs. 1 to 10 inclusive,

but separation may be readily obtained when desired, as for instance for renewal of an upper roll, by removal of pins 55, whereupon the supplemental frame may be readily withdrawn transversely from the position shown in Fig. 14. Pins 55 may pass through plates 54 and into angle pieces 60 which normally serve to limit vertical movement of the upper roll shaft bearing block.

1 It will be readily understood that any suitable supplemental drain board construction may be associated with the trough of the base, but this detail forms no part of my present invention and therefore is not indicated in the drawings.

It will also be understood that, in any of the forms a single bar spring or leaf spring may be substituted for the coiled springs shown, without departing from my invention.
