Patented June 6, 1933 UNITED STATES PATENT OFFICE EDWARD ENGEL, or isnoommeron, ILLINOIS, ASSIGNOR 'ro muniams mm'orac'rnnme conrona'rrcn, or SALEM, 01110, .A'COBPOZRATION on NEW YORK wnmenn Application filed December 2, 1931. Serial No. 578,450.

The object of my'invention is to provide an improved mechanism for readily associatmg an dissociating the two coactlng rollers of a f wringer.

The accompanying drawing illustrates my invention in an embodiment suitable for ordinary household use.

Fig. 1 is a vertical axlalsection in partial tical section just inside the end wall of the base or main frame, and 1 Fig. 3 is a plan on a smaller scale.

In the drawing 10 indieatesa main frame or base, conveniently formed of sheet met-a1, and comprising hollow end standards 11,

oppositely extending aprons 12, guard wings 13 and an intermediate trough 14 perforated in its bottom at 15.

Each end standard is provided, in a common manner, with a vertical guide, open at its upper end for the reception and support ofjlsu al bearing blocks 16 of the'lower roller 17 and for the reception of usual bearing blocks 18 of the upper roller 19.

The above-described construction is wellknown in the art and, in detail, may be varied through a wide range.

Theupper' end of each standard 11 is partially closed by inwardly" extending blocks 20, 20, each of which is provided with a vertical threaded perforation 21 within which is screwed the upper threaded end of. a de- 35 pending bolt 22, normally held against rotation in its block by check nut 23. Each bolt is projected through an ear 24 at, the lower end of an upwardly extending connector plate 25, one of which lies just inside the outer end wall of one of the hollow standards 11 and the ears 24 normally resting upon the heads 22' of the bolts. The upper end 0 p1ate'25 lies between blocks 20. v I

Resting upon each ear 24 is the lower end 5 of a compression spring 26 sleeved over a bolt 22 and initially compressed by an adjusting nut 27 threaded on the bolt.

' One of the connector plates is vertically slotted at its lower end, between its ears 24 by a slot 30 through which the shaft of the lower roller 17 may project.

"In commercial practice both connector plates will be so slotted.

Each connector plate 25 is provided, near: its upper end, on its inner face with an inwar ly projecting pin 31 upon which ispreferably rotatably mounted a roll 32.

- An upper frame or cross piece 35, conveniently formed of sheet metal and shapedso as" 7 to sleeve over the up er ends of standards-ll has journaled thereln a rock shaft 40, the ends of which are exposed, and to these ends are connected arms 41 with their outer ends in convenient access by the operator. The outer ends of the two arms 41 are connected by a cross bar 42. This cross bar 42 may be omitted if. desired.

Secured to rock shaft 40, near each end and within the cross head 35, is a cam plate 45, provided with a segmental arcuate cam flange 46 adapted, by oscillation of rock shaft 40, to take under the adjacent roll 32 and thus connect the cross bar withsprings 26. The cam flange 46 may be so formed as to take under rolls 32 without initially stressing springs 26, but in practice these cam flanges are generally so formed that, while their outer ends will pass freely under rolls 32, the intermediate portion of the flange will positively engage the rolls (when arms 41 are in their medial upright positions) so as to place springs 26 under slight initial compression. The precise curvature of the cam flanges 46 may be varied through a wide range and departures from 'concentricity with the axis of the rock shaft will be ordinarily so slight that no special means need be provided for retaining the operatin arms 41 in their medial vertical position. nsurance to this end may be provided, in a well-known manner, by providing a shallow notch in the upper face of each cam flange at its middle, (not shown). 1

The cross head 35, near each end, is provided with a transverse bar 50' arranged to form seats for the upper sides of the upper roller bearing blocks 18, the parts being so proportioned that transverse bars 50 will be in engagement with the bearing blocks 18 and goller 1-9 will be in engagement with roller 1 With the parts in the positions shown in the drawing introduction of material between the rollers 17 and 19 will displace roller 19 upwardly, thus causing bearing blocks 18 to lift transverse bars 50 and the cross head 35, thereby shifting cams 45 upwardly against rolls 32 and stressing springs Rolls 32 may be properly positioned for coaction withcam flanges 46 by axial adj ustment of bolts 22, as will be readily apparent.

The up r end of each connector plate is vertica y medially slotted, asindicated at 51 to straddle the rock shaft and thus serve to take the lateral thrust of the cam flanges 46 on rolls 32. a

Beneath each apron 12 is an outwardly and downwardly inclined drain pan 60 and the gap between the inner edges of these drain pans is bridged b a rocking drain pan 61 rovided at one en with a pivot pin 62 sli ably projected through an opening in one end wall of the base, and at the other end with a sprin ivot pin 63, the outer end of which is sli ably projected through an opening64 in the opposite end wall of the base, the arrangement bein the spring pivotpin may be readily retracted from engagement with the base and thus permit the tilting drain pan to be readily withdrawn for cleansing. g

I Thidr'ain pan at one end is provided with a" for ed projection 65, radially distanced from the axis of the pivot pins, and pro'ecti into this fork 'is a finger 66 carried y a Sp it collar 67 frictionall journaled on the s aft of the lower roller, t e two parts of this a collar being held in yielding frictional enknown form. I

gaglement. with the shaft by a spring clip 68 of we By rocking the rock shaft in either direction from its medial position, the cam flanges will be withdrawn from beneath the rolls 32, thereby disconnecting the upper roller 19 from'the influence of springs 26, and the upper cross-head may then be lifted clearfrom the base, whereupon the upper roller 19 with its bearings may be extracted. To reassem-- ble the parts, the upper roller is placed on'the lower roller with its bearing blocks 18 in the Eideways in standards 11. Rock shaft 40 ing thrown to one Or the other of its extreme position, cross bar 35 may now be sleeved down over the upper ends of standards 11 with its transverse bars overl ing the bearinghblocks 18, wheleupon, by roc ing the rock s ft to its medial position, the cam such that a cross head having abutments for bearing blocks of the upper wringer roller, a rock shaft journaled in said cross head and provided with means external of the cross-head by which it may be mani ulated, and projections carried bysaid roci: shaft laterally interlockable in one direction with the connector plates by angular movement of the rock shaft.

2. A wringer comprising, a base having hollow end standards, a pair of depending lated, and projections carried by said rock shaft laterally interlockable in one direction with the connector plates by angular movement of the rock shaft.

-3.' A wringer comprising a base having hollow end standards, a pair of depending bolts mounted within each end standard and axially adjustable therein, a coiled spring mounted upon each bolt within the end standard, a connector plate mounted within each end standard and engaging the springs there- 'in, a cross-head having abutments for bearing blocks of the upper wringer roller, a rock shaft journaled in said ross-head and provided with means external of the cross head by which it may be manipulated, and projections carried by said rock Shaft laterally interlockable in one direction with the connector plates by angular movement of the fock shaft. 3

' 4. A wringer comprising a hollow base, a

tiltable, pan medially mounted in the lower fulcrum with the base and to permit lateral extraction of the pan from the base.

In witness whereof, I have hereunto set my hand at Bloomington, Illinois, this 21st day of November, A. D. one thousand nine hundred and thirty-one. Y

I EDWARD ENGELQ flanges 46 will pass vunder the rolls 32,- thereby tying the upper roller to the springs 26.

I claim as my invention: 1. A wringer comprising, a base liav'ing hollow end standards, spring means anchored in'eachof said end standards, a connector plate mounted in each of said standards and associated with the adjacent spring means,
