Figure 9 is a fragmentary view of the structure shown at the upper lefthand portion of Figure l, somewhat enlarged, has been released, the securing member being shown in tilted position and the top cover being shown elevated more tha-nnormal in order to illustrate which partsmove with the top cover.

Any usual type of wringer frame is denoted at f2 after the top cover .v

" ing movement of said shaft I while 2 indicates each of its drain boards, and 2 its gear box.

Erected in each end of the frame is a springtension member of two parts 3 and 4, the former in this instance including two spacedtubular legs 5 each a screw, for example, let

The upper end of the yoke portion of the member li is provided with a head 9 from which a hook portion I D extends laterally for a purpose to be made known later, said head having a.

shoulder 9 also for a purpose to be named. The lower end` of said member 3 is provided with a vcircular opening II between the legs 5, and a slot I2 communicating therewith opens through the extremity of said member. The said slot at one'side of the center of the opening and lyingv just above the latter is an abutment I3 whose purpose is to be made known.

Lying lengthwise of the wringer frame and journaled in-parts of the same is a rock-shaft I4 provided with an operating lever I4 and having a notch I5 near each end severing the same for substantially one half its diameter, in this instance, the resultant reduced neck portion adapted when in the position shown in Figure 7 topass through the described slot I 2y of the member 3 as the latter is dropped thereover. Adjacent the notch and Aparalleling the nat surface of said neck the shaft carries a pin I 6 adapted in a rockto engage the named abutment I3, and, normally, the member 3, 4 is supportedV on the rock shaft as shown in Figure 4.

The lower wringer roll is denoted at I'I its shaft ends extending through bearing blocks I8 supported on abutments I3 of the wringer frame, said blocks lying between anges 20 of said frame, see Figure 4 particularly, and the upper roll 2I is carried by bearings 22 depending from a top closure member 23 as best shown in the gure last named,V said bearing likewise lying between the named anges 2B, said bearings each having an extended lug 22.

The depending walls of the closure member close the upper portion of the wringer frame and extending from the inner surface of each end wall thereof is a projection or abutment 24 in position to receive upon it the hook portion I 0 of the head 9v on the member 4. In the fastening movement, the outer ends of the portions I0 engage' the under and facing surfaces' of the projections 24, and the latter ride down until the upper edge of the projections 24 slip under the laterally projecting jaw of the portions II).

Means for locking the portions I and projection 24 will now be described. Mounted centrally upon the closure member 23 is a knob 25 from which a shaft 26 extends adapted to reciprocate within said member, its inner end having aixed thereto a cross-arm 21. Pivotally connected to each end of the cross-arms is a member 28 the free end of each of the latter adapted to abutl one of the heads 9 just referred to, the said free ends of the members 28 being supported on parts of the bearings 22 for the upper roller 2I, the thus connected parts 21 and 28 forming a toggle arrangement.

A spring 29 is interposed between the knob 25 and the closure member whose purpose is to constantly maintain a lifting action of the said cross arm, the latter in one of its positions adapted to lie between a pair of posts 39, Figure 2a, of unequal length, which depend from said member 23. I f

The wringer structure described is so designed tha-t the operating parts thereof may be removed and replaced in exact working positions without the need of a tool of any nature, such removal and replacement being attended with perfect freedom and exactness of results.

The members 3, 4 which serve, as will presently be understood, to secure the wringer rolls in operative positions, are positively secured in position during wringer operation on said rock shaft and yet may be readily removed from the latter as occasion demands. That is to say, when the rock-shaft I4 lies in the position shown in Figure 4 within the opening II of said member 3, 4 it is clear that the latter is firmly held without respect to the degree of upward pull transmitted thereto in the wringing operation of the rolls. On the other hand when the parts lie as shown in Figure '7 the member 3, 4 is free to be raised and may be lifted by the operators fingers. However, lifting may also be done mechanically as the pin I6 rotates with the rockshaft from the position of the latter shown in Figure 4 to that shown in Figure '1, said pin while moving from the intermediate position of Figure 3, to that in said Figure 7 lifting said member 3, 4 by engaging the named abutment I3.

It is noted that the lower roll I1 since supported on the abutments I9 receives the pressure of the upper roll 2| the latter rising and falling according to the bulk of material treated.

It has been stated that the hook portion Ii) of the member 4 engages upon the projection 24 of the closure member 23. This relation exists while the wringer is in condition for operation. It is to be observed that when the toggle arrangement made up of the cross-arm 21 and members 28. lies as shown in Figure 2 the ends of said members are held in rm engagement with the heads Shaving. said hook-portions I9 thus maintaining positive engagement of the projections 24.

At this time the toggle lies between the posts 39 and it is thus prevented changing position, the knob 25 being held in its highest. position due to the expanding action of the spring 28.

I'n said Figure 2^ the toggle as shown in broken lines hasy been depressed by a downward pressure onsaid` knob and has passed below and has been shifted beneath the shorter ofV the two Vsaid posts 39 as the offl position which releases the latter with the closure member when the hook-portions I0 leave the projections 24.

When assembled for operation the springs 1 of the spring-tension member are placed under compression. This is due to the fact that the distance between the rock-shaft I4 and the top surfaces of the projections 24 of the closuremember 23 is greater than the distance between the said shaft opening II of the part 3 and the hook-portions I0 of the member 4 of the said spring-tension member when the latter is not under strain. Thus a downward pull is exerted ruponv the closure-member 23 and a consequent pressure of the upper wringer-roll upon the lower roll. supposing that all of the described inner parts of the wringer lie outside the wringerframe the assembling operation is as follows: The spring- tension members 3, 4 are lowered into the frame upon the rock-shaft.

Following this, the shaft of the lower roll II with its bearings I8 is lowered to position while causing it to engage with the power shaft of the gear-box 2, the said bearings lodging upon the abutments I9. i

The closure-member 23 with the suspended roll 2l is now placed in position. At this time if it so happens that the spring- tension members 3, 4 have been placed in locking engagement with the rock-shaft, the latter is rotated to cause its pins to lift the said members to a position to carry the hook-portions I9 thereof above the projections 24 of the closure-member 23, whereupon the knob 25 of the latter is turned to cause the members 28 of the toggle to abut the heads 9 to spread them apart as far as possible so that the said hook portions are positively held in overlying engagement with said projections 24. At this time the toggle parts assume the position shown in continuous lines in Figure 2 between the posts 30 where it is positively held after the spring 29 of the knob raises it. At this time, also the rock-shaft I4, which has been lying in the position shown in Figure 7, is rotated clockwise, looking at Figure 7. This action, as a study of Fig. '1 will show, causes the half portion of said shaft to engage at one corner with the corner of the member 4 at the opening II, and acting as a cam, draws the member 4 downward so that nally the rounded half-portion of the shaft lies wholly within said opening II, see Figure 4. This action has placed the spring 1 under tension and a yielding strain has been placed upon the upper roll 2I through the closure-member 23 due to engagement of the projection or abutment 24 thereof and said hook portion I0 of the member 4.

Attention is again drawn to the toggle arrangement in the closure 23. In the released position of the toggle the connected end of a member 28 and the cross-arm, as shown in broken lines in Figures 2 and 2a, lies beneath the shortest post 3,0. When the knob is turned to hold the portions I0 against the closure 23 above the lugs 24 the members 28 are moved endvvise and both bear upon the heads 9. As the members are brought more nearly in line with each other they span the space between said heads which are forced apart sufficiently to permit an end of the cross-arm 21 to pass just beyond and behind the short post 39 where it lodges due to the expanding action of the spring 29.

The release of the pressure of the upper roll is accomplished by a sharp blow upon the knob 25. This act depresses the cross-arm 21 to a position where in passing below the short post 3B the toggle due to the tension thereon inl holding the heads 9, against the downward action of the spring tension members 3 and 4 will shift its position to the named broken lines position of Figure 2. The engagement between the hooked rportion H3 and the projection 2E is unstable, the

former being prevented from slipping off from the latter by the thrusting action of the arms 28 when the closure is in the operative position and the rolls are under compression. The position of the hook portion Hl and the projection 2li after disengagement is illustrated in Fig. 9, the tilted position of the members 3 and 4 being apparent in that the lower end of the member 3 is closer to the wringer frame l at the bottom than at the upper portion of 3. In Fig, 9, `the member 28 is retracted and no longer thrusts against the head 9 of the hook portion l5. As illustrated in Figure 9, the cover 23and the parts including the upper roller 2| are shown substantially suspended in the air, thus to illustrate which parts move with the cover when the hook 9 leaves the projection 24. In the position shown, the lug 22 and the shoulder 9 may be considered as having struck each other and 22 having fallen downward somewhat, or it might be considered that 22 is illustrated as moving upward and approaching the shoulder S. Since, now, the heads 9 are released by the retraction of the members 28 the springs 'I of the spring- tension member 3, 4 Withdraw the hook-portions I0 from the projections 24, freeing the roll 2|, the members 3, 4 tilting sufciently to permit such action.

The sudden release of the roll 2l, especially when work lies between the roll, tends to lift the closure-member 23 and the upper roll clear of the body I, but this is preventedv by the lugs 22' of the bearings 22, see Figure la, meeting the eX- tended shoulder 9 of the head 9.

The whole arrangement is such, as is Vnow clear, that the parts are all independent of each other and of the body l so they may be removed and replaced readily and without tools. Also, that such arrangement provides for full control of all of the parts while inaction besides having a proper and positive locking of all such parts as require it. While a preferred structure has been shown and described it is understood that equivalent means may be used such as may be considered to lie within the meaningof the claims s.

to follow.

The manner in which the elements 28 engage the heads 9 to hold the hook portions Hl` over the projections 24 is also disclosed and illustrated in our co-pending application Serial No. 172,819,

led November 4, 1937.
