WRINGER.

'Application filed November According to my "invention the wrin'ger which comprises "a set of rolls and a hinge -over, is provided with aspring for exertm pi-essure on the rolls, and means for maintaining the spring in, :or for instan taneously releasing it irom, pressure entertingirelation :withfthe rolls.

In the preferred embodiment of *the in vention the cover isfconstruc ted interio'rly with supporting members above and parallel with the journals of the rolls and a flat spring is placed within the cover and its end's ar'e loosely mounted on the supporting members. Pressure blocks are seated onthe journals of the uppermost rollfand eXtend above the supporting m'cmbers to'beengaged by the spring. rotatably adjustable cam or dis'o is mounted in the coverandrengages the spring for varying the pressure exerted by it on therolls, and a cranlcor the'like effects the rotatable adjustment of the cam "or disc. 7 j

The com is exteriorly provided with lockingmembers which may take the form of lateral projections; and a reciprocatingly movable locking barisslidably connected to the wringer frame and is provided wvith locking memberswhich may take the form.

of l elongated hooks -for engaging the ilocking members of th'ecover. A lever 18 .fulcrumed to thewrin er *frame for actuatin the locking bar'and the movement of this lever in one directiolrbrings the locking =members into engagement for securing the cover and the movement of the lever in the opposite directionactuates the lockingbar forthe instantaneous release of thelocking members.

For an understanding of the invention -1eterenc-e is to be-had to the following description and to the accompanying drawings, in Which: I s Fig. 1 is a plan View of a 'Wring'er-constructed according to this invention,

parts throughoutthe specification and drawings. a s v Journalled in the main frame '25 are two wringer rolls 31 31 and bearing on the our- .nals of the roll 31 are pressure, ,orfijojurnal, blocks 32. Hinged to the top of ithemain frame 25 is the cover 33 "provided with a downturned flange'34, and-extending through the flange 34% ;are two supportingmembers '35, the axles of which are parallel with the journals of the roll 31.

on the blocks 32, andythe ends of this spring loosely rest on-Mthe supporting members :35 when the cover part is released by the looking bar 40 hereinafter(described. Centrally journa'-led in the 'topofthe cover is the axle 37 of a rotatable cam 'or Le'ccentrically anounted disc 38, and {fitted on the end of the" axle r-beyond'the {cover 33, is a :crank '39. The disc continuously engages the spring 36 and. when vrotated varies %the tension of the spring. The pressure blocks BQeXtend above the supporting members 35 whenthe cover is in a closed position &and {lift the ends of the spring from, (the supporting members so that when-the coveris closed and'secured in its closed position, ithespring willEbent all times in pressure exerting relation with the blocks and'by uneans :of the latter ;with the Avringer roll '31. dlvhen ithefdisc 38 is rotated to, the ;Position shown in dotted lines Within the cover 3551s a leafspring36 for exertingpress'nre in'Fig. 3, the spring 36istensiQnEd-iOtlm then in the position shown in fullelines in Fig. 31and'engages thecover 33.

and r by '1 the weight I :Other 'types of springs andtension devices l may be employed in lieu of the specific type shown and described and it not intended that the invention should be limited to this specific construction. I

The cover, including the pressure exerting means, are for convenience, termed the cover part, and for holding the cover part in operative relation with the wringer rolls, a

closed position and maintain the spring in pressure exerting relation with the rolls. The'hooks on the locking bar are comparatively long and so shaped that they draw the hinged cover down to its locked position and impose the pressure of the spring on the pressure blocks 32.

At the bottom of each hook 43 is a slight recess into which the projections 44 drop when the locking bar is moved to the limit of its locking position, for preventing the inadvertent displacement of the hooks from the projections 44. Extending horizontally from the locking bar is a lug 45 formed with a slot 46 through which is entered a wringer release lever 47, the lower end of which is fulcrumed at 48 to the main frame 25. The actuation of the lever 47, operating through the slot 46, effects the movement of the locking bar in one direction for the engagement 7 of the hooks 43 with the projections 44 and in the opposite direction for the release of the hooks from them. The release of the locking bar from the projections immediately releases the cover part and relieves the pressure of the spring on the blocks 32 and wringer roll 31, the ends of the spring then resting on. the supporting members 35.

Having thus fully described my in run tion what I claim as new a nd desire to secure by I Letters Patent is:

l. A wringor comprising a wringer frame, a set of rolls therein, a hinged cover for the rolls, a spring within the cover for exerting pressure on the rolls, a rotatable eccentric disc engaging the spring for varying the pressure exerted by it on the rolls, and a reciprocatingly movable locking bar having a shdable connection with the wringer frame for securing the cover and maintaining the spring in pressure exerting relation with the roll s.
