I have exemplified my improved device as applied to a wringer of the character of that shown. described and claimed in my LettersPatent of the United States No. 1.932288, for Wringer, dated October 24, 1933, and thegeneral structure and purpose of the relieving bar of general inverted U-form such-as herein shown and described is disclosed in my Letters Patent of the United States on improvements in cross-bar bent therefrom. Clothes guards H! are located at the inner faces 2 Wringers, No. 1,408,807, dated March 7, 1922, and No. 1,810,479, dated June 16; 1931. J

In the present exemplification there is a rigid frame H which comprisesa longitudinally extending base I2. from the respective ends of which posts l3, l4 extend upwardly. The frame is shown. made of sheetmetal bent into channel.

form. The respective sides of the frameare provided with downwardly sloping shelves I5,. having upwardly extending end flanges l6 curvingly of the upright posts, the clothes guards and such inner faces and the inner walls of the upright posts being provided with upright slots l9.

wringer rolls 2|, 22 are provided with shafts 23, 24. vLower bearings 25 and upper bearings 26 are located in the channels of the upright posts, the shafts of the wringer rolls being journaled in these bearings. One of the shafts may have one end extended through a slot 21 in the outer wall of one of the posts and be provided with suitable means, exemplified at 28, for attachment of a driving means.

A longitudinal bar 3| resists pressure between the wringer rolls. It is shown as a top bar extending between the upper ends of the posts, and is shown provided withpan upper wall 32, depending side walls 33 and depending end walls 34, 35, forming a downwardly opening hollow 36 in the top bar. The. upper ends ofthe posts are received in the ends of this hollow in the top bar, the top bar being received canopywise over the upper ends of the posts.

This bar is movably secured to the. frame, permitting pressure to be exerted upon the wringer rolls, and quick release means are provided per.-

mitting relief of such pressure when the top the top bar and the wringer rolls, the respective ends of the bow spring extending through the slots I9 in the inner walls of the upright. posts and resting upon the upper bearings 26 of the wringer rolls. It has a seat 40 in its middle portion, receiving the lower rounded end of a screw 4| having threaded connection 42 with a nut 43 secured to and extending through the top bar, the screw having a knob 44 at its upper end for rotating the same.

There is a releasable connection 48 between one end of the top bar and one of the posts, arranged to be released and connected by opposite endwise movements of the top bar. It is exemplified as comprising a knob 49 received in a hole 50, the knob beingshown on the post and the hole in the end wall of the top bar. The

hole is preferably elongated as a slot for readily receiving the knob.

A linkage mechanism Si is provided for conmeeting the other end of the longitudinal bar and the frame, and is exemplified as a link 52 having pivot connection 53 with the end of the top bar and a link 54 having pivot connection 55 with a post adjacent to its upper end. These links extend from these pivot connections, and are interpivoted at their outer ends by a pivot 56. The link 52 is extended beyond the pivot 56 to form a lever. The outer end of the lever forms a handle 51.

This lever is preferably formed out of sheet metal, with an inwardly extending marginal flange 6|, the pivots 53, 56 having bearings at their opposite ends in opposite portions of this flange.

The pivot 53 has bearing 62 in a bracket 63 fixed to the end wall 34 of the top bar, the bearing extending outwardly from this end wall. The pivot 55 has bearings in lugs 64 struck outwardly from theupper end of the post. The marginal flange of the lever forms a pocket in the inner face of the lever. The inner portions of the pivots 53, 56 and the bearings therefor, as well as the link 54 and the pivot 55 and its bearings, are received in the pocket of the lever when the lever is moved toward the frame in operative relation, to provide compactness of parts, to conceal the covered parts, and to provide a flush and pleasing appearance for the linkage connecting end of the wringer.

The pivot 56 forms a toggle between the links 52, 54, that is, between the operating lever and the link 54, so arranged that when the lever is moved toward operative position for placing the parts for pressure relation between the rolls, the pivot 56 is moved toward the plane, exemplified by the dot and dash line 65, in Fig. '7, in which the axes of the pivots 53 and 55 are located, for drawing the top bar or frame, which may be considered as a frame part, toward the main frame for connecting said parts for pressure between the wringer rolls. This places the pivot. 56 proximate to said plane, but preferably at the outside thereof, so that there is preferably a tendency toward separation between said parts.

Movement of the pivot 58 toward the plane in which the pivots 53, 55 are located, moves the links 52, 54 from the acute angular relation exemplified in Fig. 8 into substantial parallelism, exemplified in Fig. '7, thereby drawing the connected parts toward each other into operative relation.

A latch 68 is provided for releasably holding the parts in such relation. The latch has a hook 69 received over a lug 'lll fixed to the lever. It is provided with pivot lugs II, forming bearings about a pivot pin I2, located in bearing holes I3 in the frame. The latch is provided with a cam part I l, shown extending inwardly therefrom to form a lever. A spring I is fixed to the frame and bears against the lever, as against the cam-formed tail thereof, for resiliently urging the latch into engaging relation. The lug I0 is provided with an inclined face I6, upon which the hook end of the latch rides into engagement with the lug when the lever is moved toward the frame.

The means exemplified for releasing the latch comprise a cross-bar 80, provided with oppositely extending cam faces 82, 83 coacting with the cam part of the latch. The oppositely presented cam faces on the cross-bar and the contact part therefor on the latch may, of course, be reversed if desired. There is a further cross-bar 8 i. The crossbars may each be a piece of sheet metal bent to have a top wall 84, depending side walls 85 and end walls 86, the opposing cam faces being shown formed in one of the side walls.

Means are provided so that the cross-bar may be operated from each side of the wringer by movement in either direction. and means are provided at each side of the wringer for effecting such movement. There is a releasing bar of general inverted U-form, such as exemplified in my aforesaid patents, Nos, 1,408,807 and 1810,479. at each side of the wringer. Each of these releasing bar 81 comprises a top or hand rail 88 and depending sides 89, 90. arranged about the top and end of the wringer oll opening in the front and rear of the frame. The hand rails are parallel to each other. Each of the posts has at each side thereof a bearing bracket 9| fixed to the wall of the post, as by spot-welding. and pref erably formed up out of sheet metal, and having a bearing 92 therein for the downwardly extending branch of the releasing bar. Each of these downwardly extending branches is proximate to this point provided with an inward bend 93 for projecting the upper ends of the releasing bars slantingly outward for placing them in positions to be readily grasped by the operatrix in case she desires to take quick action in separating the rolls. Any part of each of these releasing bars may be moved toward or from the Wringer frame for such release.

The lower ends of the depending sides of these releasing bars are reduced in cross-section, as shown at 94, to form stems received in bearings 95 in the cross-bar 80, 8| and shoulders 96 to rest upon the cross-bars. Each of these depending sides has an enlargement 91, shown as a screw threaded into the bar under its bearing 92 for holding the bar downwardly.

Each of the brackets 9| is provided with an inwardly extending portion 98, extending through a slot 99 in the respective front and rear walls of the posts, to form shelves on which the lower bearings of the wringer rolls rest.

The front and rear walls of the posts are also provided with holes I00 of cross-sectional form. similar to that of the cross-bars 80, 8|, to form bearings in which these cross-bars lide endwise.

In order to hold the cam mechanism between the cross-bar and the latch normally in neutral relation, I provide the cross-bar BI sliding endwise in its bearings. This cross-bar may be devoid of the oppositely presented cam face 82, 83. if desired.

Oppositely acting springs IOI, I02 are received about the cross-bar 8| inside the channel of the frame between the front and rear walls of the frame. A pin I03 is in the middle portion of the cross-bar 8I between the springs. This pin may be a, cotter-pin received through a hole I04 in the middle of the cross-bar, and positions the inner ends of the springs. When one of the releasing levers is moved in one direction, one of the springs is compressed, and when either of the releasing levers is moved in the opposite direction, the other of the springs is compressed, the springs returning the operating levers to normal positions and returning the cam-actuating means for the latch into normal relation upon release of the operating levers.

A keeper I05 shown formed in the top of the post I3 receives the end wall 34 of the top bar and holds the top bar from automatically returning about the post l3 nd prevents automatic reengagement of the releasable connection 48, for keeping the parts in release relation.

In case of accident the operatrix may quickly 80 actuating the latch 58 for movement of the lever 51 in releasin direction, whereby the toggle links 52, 54 are moved into release relation, the parts in the present exemplification being moved from their relation shown in Fig. 7 to their relation shown in Fig. 8 by the pressure between the wringer rolls.

During this movement of the parts, the end wall 34 of the top bar is raised above the top of the post l3 and the top bar is moved longitudinally for releasing the releasable connection 48. for removing all pressure between the wringer rolls and permitting raising of the upper roll and the top bar and the parts therebetween for com: plete release of everything which may be between the rolls.

Upon descent of the raised end of the top bar the end wall 34. engages the keeper I05 and prevents automaticreengagement of the releasable connection 48 for holding the parts in release relation. Explaining the operation more in detail, and referring particularly to Figs. 7 and 8. it may be stated that upon sudden release of the pressure upon the spring 39 and consequent release of pressure between the.wringer rolls due to release of the latch 68 in the present exemplification, asudden upward movement is im parted to that portion of the top bar with which the spring connects, being the middle portion of the top bar in the present exemplification.

The right-hand end of the top bar as viewed in Fig. 7 is momentarily held to the main frame by the releasable connection 48, causing the motion of the top bar to be translated into an arcuate motion about the releasable connection 48 as a center. for swingingthe left hand end of.

the pivot 53 carries the lever 51 with it and swings the lever upwardly upon the pivot 53. qualified by the outward swinging movement of the link 54 about its pivot 55 on the main frame, and the pivot connection 56 between the swinging end of this link 54 and the lever.

This reacts upon the upper end of the link portion 52 of the lever, which is that portion of the lever above the pivot 56, as hereinbefore explained, and which is longer than the link 54, moving this upper end of the link portion 52 of the lever inwardly toward the vertical plane in which the post I3 is located, and above this post. thereby raising the end wall 34 of the top bar above this post and tilting the top bar upon its releasable connection 48, and automatically moving the top bar endwise to the right with relation to the posts. as viewed in Fig. 8, thereby moving the end wall 35 of the top bar and the wall of. its hole 50 beyond the knob 49. whereby this end of the top bar is released. 1

This action or sequence of movements of the parts is extremely rapid, and it may be said al- -most instantaneous, the recoilof the spring 39 practically shooting the parts through the motions stated due to their connections. The upward and endwise movement of the top bar is limited by the links 52, 54 and their pivotal con nections. preventing dangerousjextent of move ment of the top bar and its connectedparts.

The releasable connection 48 holds the right hand end of the top barto the post l4during the initial portion of these movements, whereby forceful upward movement of the-right hand end of the top bar is preventedfremoving all danger from the movements of the parts, and during the balance of these movements the right hand end of the top bar rests upon the post I4.

The pivot 56 may during the release motion rise to the level of the pivot 55 or above said level, and if strong tension is applied to the spring 59, the pivot 56 will be "raised sufficiently by the recoil of the resilient pressure of the rolls and spring upon release of the latch 68, to almost fully open the links 52. 54 with relationto each other, movement of the pivot 56 into a right line between the pivots 53, 55 when-the links are in such almost fully open relation being prevented by having the free edge of the marginal flange 5| engage the upper edge of the outer end wall of the post l3. r

The motive power for the separating move ments is the energy stored'in the resilient pressure between the wringer rolls and in'the spring 39, released by release of ent exemplification.

When the relieving movements ofthe partsf have been completed, the raised parts dropby gravity, the top bar remaining in endwise moved relation, so thatthebottom of the end wall 34' automatically becomesseated in the seat "15. as shown in Fig. 8, the effect of which is to prevent re-engagement of the releasable connection 48.

These movements are entirely. automatic, and

quick upon release of the safety latch 55;?

In this relation theftop bar with itsatt'ached 1 spring may be completely manuallyfraised from the wringer rolls by swinging. thetop bar iipwardly on its link connections with "the main frame.

If it is desired to again place thepartsin op erative relation, the end of the, top bar adjacent.

to the keeper 005 is raised and the top bar is moved longitudinally to place its end wall 34 at the outside of the post l3, thereby engaging the releasable connection. 48.. The handle 51 is then depressed for moving the togglelinks 52, 54 into substantial parallelism,.thereby exerting pressure upon the wringer rolls. the adjusting screw42 being adjusted if desired.

When the handle 51 has substantiallyreached its limit ,of movement, engagement in' the :latch 58 automatically takes place, for holding the parts in operative relation, it being understood that the hook 59 wi1l have been automatically returned to engaging position. bythe action of the, springs llll, I52 returning the crossbar Hi to normal 1 sition, which acts on both the releasing bars for returning them to normal positions. The latter act to return the cross-bar Bflto normal position.

thereby permitting the hook 59 to return to normal or latching relation, urged thereto by the spring 15.

The cupped lever 51 covers the operative parts located between it and its adlacentlpost l3.
