ATTORNEYS Patented Nov. 26, 1935 PATENT OFFICE RELEASABLE WRINGER HEAD Edward S. Erickson, Salem, Ohio, assignor to Mullins Manufacturing Corporation, Salem, Ohio, a corporation of New York Application October 23, 1933, Serial No. 694,705

3 Claims.

commercial type of wringer in which my invention hasbeen embodied;

Fig. 2 a fragmentary vertical section axially through the rolls;

Fig. 3 a fragmentary elevation of a portion of the pressure-controlling means;

Fig. 4 a vertical section of the parts shown in Fig. 3;

Fig. 5 a considerably magnified fragmentary sectional detail of the parts shown in Figs. 3 and 4;

Fig. 6a fragmentary horizontal section of the water deflector and associated parts; and

Fig. '7 a perspective of the water deflector.

In the drawing indicates the base of the wringer formed most conveniently of pressed sheet metal and comprising channel-shaped end standards I I, ll comprising vertical inner flanges l2, l2, intermediate flanges I3 and end wall I4, the flanges l2 and I3 being spaced from each other axially of the lower roller l and upper roller IE to form vertical channels for the reception of the lower roll bearing l1 and reception and guidance of the upper roll bearing carrier I8, said carrier, with its upper roll bearings being vertically extractible from the open upper end of the channel formed by the vertical flanges l2 and I3.

The bearing carriers l8 are carried by a yoke l9 provided with depending ends 20.

Pivotally associated with the yoke I9 is the upper cross bar 2| by means of which torsion springs 22, mounted in the base l0 and provided with radially-extending arms 23 pivotally associated with upwardly-extended connector plates 24, may be associated with the upper roll so as to spring-urge said upper roll upon the lower roll.

The construction thus far described is described more in detail in the Conarroe Patent 1,906,841 issued May 2nd, 1933.

In that construction cross bar 40 is provided with depending fingers 3| each of which is pivoted upon a pin 36 carried by the yoke 36, the axis of which is necessarily, when in working position, in the same vertical plane as the axes of the rolls 33 carried by the upwardly-extending connectors 28. I 5

In'order to obtain sufllcient stability of spring pressure in such a construction it was found necessary, as was pointed out in that patent, to slightly notch the finger to form a shallow pocket for the reception of the roller 33, as other- 10 wise the cross head 40, in its medial and operating position was too unstable. But it was also found that the provision of such a stabilizing pocket made it necessary for the operator, in case of accident, to exert a considerable degree of force laterally against the cross bar, to release the up-' per. roll from the operating spring pressure.

I have overcome this difliculty, without the sacrifice of stability, in the following manner:

In my present construction the cross head 2|, at 20.

each end, is provided with 9. depending finger having an outwardly-projected and slightly upwardly inclined tip 26 adapted to underride the roll 21 carried by the adjacent upwardly-extending connector 24, the same as in the above-men- 25 tioned Conarroe construction, but instead of providing a single-axis pivot pin for the connection between yoke l9 and fingers 25, I provide a twoaxis pivot pin 30 formed, as more clearly illustrated in Fig. 5, to afford two parallel fulcrums 30 3|, 3| arranged on opposite sides of the vertical plane of the axis of roller 21, these two axes 3|, 3| being most conveniently formed by slightly rounding the upper edges of the pin 30 and preferably, though not necessarily, forming a shallow clearance trough 32 therebetween in order to insure against any such accumulation of lint or other waste between the pivot edges 3|, 3| as would interfere with proper operation of the device. The finger 25 forms a swinging carrier for the tip 26, which tip has an overlapping cooperation with the roller 21.

In order to cooperate with the two-axis pin 30, finger 25 is provided with a polygonal perforation P having an upper surface 35 flanked at each end by downwardly and outwardly inclined surfaces 36, 36 so proportioned, relative to pin 30, that the junctions between the surfaces 35-36 will rest upon the edges 3|, 3|.

Perforation P as a whole is of suflicient width and height to afford freedom of movement of finger 25 on finger 30 and, in order .to insure maintenance of association of the fingers 25 and 30, the finger 30 at its outer end is provided with a laterally-extended tip 31.

With this arrangement a lateral force exerted upon cross head 2i, in either direction will pivot the fingers 25 upon that axis 3| most distant from the applied force and the fingers i! will pivot thereon. It will be noted that the arc of swing of the upper surface of tip 20, about either one of .the pivot axes 3|, is almost tangent to the roll 21 and, as the upper surface of the tip Il may now be perfectly smooth, very little lifting eflort upon the connectors 14, tending to further stress the springs 22. is necessary to withdraw tips 26 from beneath rolls 21. But it will be further noted that my construction provides ample stability of working association the springs and the upper rollers It became of the extended lateral support of finger 2| upon opposite sides of the vertical plane of the axis of roll 21.

It will be readily understood that while I have shown my improved connection in association with other details of wringer construction, the 'said improved connection may be used in various types or wringers without substantial modification.

The inner edges of the flanges l2, I! are spaced from each other so that, unless deflected, water squeezed from the clothes near the ends of the rollers l5 and It, may, unless deflected, be projected down upon the exposed ends of the lower roller axle l5 and into the open bearings of the bearing blocks H.

In order to deflect this water I have provided the inexpensive sheet metal guard or deflector shown in Figs. 2, 6 and '7, said deflector comprising a medial portion 40 having tips 40', 40, intermediate portions H, 4| and upper and lower portions 42, 42, each having tips 42', 42' and each medially notched, at 43, to fit over the exposed portions of the upper and lower roller axles l6 and I5 immediately adjacent the ends of the rollers.

The upper and lower portions 42, 42 are ofiset from the plane of the middle portion 40 an amount substantially equal to the thickness of the flanges l2, as shown in Fig. 6, so that, after the lower roller has been placedin position, 5 the deflectors may be telescoped over the flanges l2, between said flanges as clearly shown in Figs.

3 and 6.

I claim as my invention: I

1. In a wringer, the combination of a base 10 having vertically channeled end standards eomprising laterally-spaced inner channel-flanges, and a water-deflector having at each side projections spaced to telescope over one of said channel flanges, said deflector being dimensioned to bridge the space between said channel-flanges and the roller shafts. I

, 2. In a wringer, means for releasably connecting one of the two rollers to a spring, comprising two overlappable interlocking elements, a pivotally-supported swinging carrier for one of said elements, and two pivot axes for said carrier laterally spaced upon opposite sides of a plane including the axis of said one roller and the point of interlocking engagement of said overlapping elements, the engagement between axes and carrier permitting free rocking separation.

3. In a wringer means for releasably connecting one of the two rollers to a' spring, comprising a pivotally-supported swinging carrier and a support therefor, one of said last-mentioned elements forming two laterally-spaced parallel axes and the other having an axis-receiving perforation aflording two laterally-spaced contact lines for said axes and freely rookably separable therefrom, and two overlappable elements one carried by the swinging carrier and the other connected to said spring, the medial plane of engagement between said overlappable elements lying in a plane passing between said axes. 4o
