i My invention relates to wringersof the character ofthose employing opposite wring er rolls between which the goods are arranged to be passed for expressing the water, and

i 'l' my present invention is an improvement upon thedevice shown, described and claimed in i my Letters Patent No. 1,408,807, for'wringer,

dated March 7 ,1922. v

. In the wringer shown and described 1n patent the latching means are in the inside of the frame and closely adljacent tothe pivot of the movable part of 4the wringer frame.

` It is the lobject of my invention to construct 15 'theframe'oijtlie wringer in a plurality of parts each of which has a wringer-roll meunt- "ed-thereon, and 'to provide means for pivot- 'ing one framespart4 on the other frame-part 'at one side of thewringer-rolls, and means i- 20 for latching one frame-part. to the other -frame4part at the other side of the wringerrolls. v v' Itis the .object of my invention further to provide novel spring means for causing latch- 25 ing between the frame-parts and novel releasing means for the latching means operable inlopposite` directions for releasing the movable frame-part and thereby causing separation between the wringer-rolls. 1

It is the'objectof my invention further to place the actuating parts ofthe releasing i `-means'whi'chcoact with the latch at one side of the wringer frame and to provide a spring latch whichv is movable at'the outside of the frame 1 and i substantiallyA conceals said coact ing' arts. ,-f l

Fig. 7 is a detail vsectional view, taken in 'the plane ofthe line'7-7 of Fig. 5; and,

,Fig 8 is a front view of one end of my 5I improveddevice, partly broken awa The lower or base section of the ame is exemplified at 11, and may be provided with any suitable means for attaching the wringer to a support, for instance a tub or a power 6l washing machine. The lower frame-section isexemplii'ed as built up of sheet metal and comprises end pedestals 12, each of which has an upright channel'13 therein, in which there is a shelf 14. A lower bearing-15 is located in each of these upright channels on said shelf.

The shaft 18 of the lower wringer-M1119 is received in bearing recesses in the bearings.

These bearing recesses are open upwardly so 4that the wringer-roll with its shaft may be 7 readily lifted out of the bearings and removed .from the wringer or be readily replaced there- 1n. .A

The shaft 18 is provided with suitable turni ing means at its end, which may be either arn ranged for manual or for power operation. I have shown the end of the lower wringerroll provided with a tong-ue"21 which may be received in the socket of a suitable power driven .member of power driving means for U rotating the shaft. l s y An upper wringer-rollv 25 coacts with the lower wringer-roll and'is mountedvon ashaft 26. The shaft 26 is journaledin bearings 27 vat its respective ends. 1` The bearings 15 and n 27 may be blocks of treated wood, treated for reducing friction. Each of the bearing blocks 27 is4 received in a strap 28 which is received about the top and sides of the block and has lips 29 at the bottom ofthe block. This strap 9. is open-ended for endwise removal of the bearing. u

The straps are adjustable up land down in yokes 31 nat the .respective ends of the machine. The yokes are connected by' a connectrespective yokes, as by' screws 3 Adfjusting screws 34 are adjustable in 1 threa ed bearings 35-in the respective yokes. The adjusting screws have swivel connection n ing bar 32, which isrigidly `connected with the with the respective straps.j Each of the adjusting screws has a ball 36 at its lower end which is received in a complemental socket 37 formed in the upper portion of the strap. Each of the adjusting screws is provided with a knurled head 38 for turning the same.

The upper wringer-roll is arranged to be driven from the lower wringer-roll, as by providing the respective wringer-rolls (with.

toothed driving sections 41, 42, for instance as shown, described and claimed in my Patent No. 1,516,886, for wringer roll dated November 25, 1924.

have preferred to divide the frame of thev wringer into frame-sections which su port the respective opposed wringer-rolls, fbrming what I term a break-down frame, and to provide means whereby the pressure mechanism which causes pressure between the wrin er-rolls while the goods are passing there etween is part of one of the frame-sections.

I have provided springs 46 for exerting pressure between the wringer-rolls. These springs are interposed between the two parts of the movable section of the 4wringer-frame.

One of these movable parts is pivoted to the relatively stationary or base section of the wringer-frame hereinbefore described, and the other of these parts is arranged to support the upper wringer-roll 25.

The lower frame-section is provided with pivot-lugs 47 and the upper frame-section comprises pivot-parts 48 from which pivotlugs 49 extend. Pivot-screws 50 are received in the pivot- lugs 47, 49, at the respective ends of the machine for pivoting the upper framesection to the lower frame-section.

The springs-46 are shown as bow-springs with the ends of the bows of the respective springs adjacent to each other. The lower leaves 53 of the respective bow-springsare fixed to the respective pivot-parts 48, 'as by rivets 54, at points vdistanced from the ends of said leaves, leaving extensions 55 of said leaves which extend forwardly from said pivot portions and are located between the shafts of the coacting wringer-rolls and are provided with catching portions 56 at their forward ends, preferably having lower bevel faces 57. v

The yokes 31 are provided with rearwardly extending lugs 58 to which the forward ends of the upper leaves 59 of the bow-springs are respectively fixed, as by means of rivets 60.

A sprin latch is provided at each end of the lower rame-section for coaction with the catch at the forward end of e'ach of the lower leaves of the bow-springs, for holding the upper frame-section in operative relation with the lower frame-section, and holding the wringer-rolls inoperative relation with each other, with pressurebetween vthe rolls for wringing the clothes.

Each of the latches is shown as comprising a keeper 64 having' an upper bevel-face 65, with which the lower bevel-face 57 on the catch at the forward end of the lower leaf of the bow-spring coacts. The keeper is at the upper end of a leaf-spring 66, the lower end of which is secured to the lower framesection, as by screws 67 received through the leaf-spring andthrea-ded into the front wall of the lower frame-section.

One of these eaf springs extends upwardly alongI the front wall of the upwardly extending pedestal or pillar o-f the lower framesection at each end of the lower frame-section. The resilience of the leaf-spring presses thel latches toward the wringer-rolls and toward the catches when the latter are in latching position, the latches being normally resilicntly pushed forwardly by the catches when swinging the upper frame-section on its pivots for engagement of the catches under the latches, the latches rebounding above the catches when the latter have been forced downwardly to sufficient extent.

This connection between the catches and the latches is preferably accomplished by a quick snap movement of the upper framesection into working position, as by grasping the bow portions of the bow-springs in the hands and imparting a quick pivotal movement of the upper frame-section about its pivots, or pressing downwardly on the yoke members or connecting bar of the upper frame-section for engaging the catches under the latches.

I provide quick releasing means for the latches, shown comprising a lever 71 at each end of the frame. Each of these levers is pivoted by a pivot 72 to the lower framesection at the respective ends of the lower frame-section. The lower ends of the levers are received inside the 4outer walls 73 of the pedestals 12 at the respective ends of the machine. The pivot is shown in the form of a bolt received through a pivot-hole 74 in each of the levers, the lever being located between the head 75 of the pivot-bolt and the inner face of the outer wall 73. A nut 76 is threaded over the outer end of the pivotvbolt for holding the pivot-bolt in place.

A cross-bar 79 is secured to the upper ends of the levers 71 forconnecting the levers. These connections are preferabl rigid for causing combined movements o the levers the levers to the bar.

Each of the levers is provided with contact- lugs 82, 83, arranged to contact respectively with a contact-lip 84 extending from the leaf-spring 66. The contact-lu s extend through a slot 85 in the front wall othe pedestal. The leaf-spring and its contact-lip extend laterally across the pedestal and across said slot to hide the slot and prevent the catching ofclothes therein. A'substanvtially closed structure is thus provided for hiding and protecting the latch releasing parts and for removing these' parts from coutact by the clothes.

he respective lugs 82, 83'are respectively above and below the pivot 72, so that forward movement of either of said lugs acts to release the latch, at each end of the machine. The lower p'ortion'86'of each of the-levers 71, in which the pivot 72'and the lugs 82, 83, are located, is at' the forward side of the shafts of the wringer-rolls, and distanced'from the pivots of the movable 'frame-section, which are at the-other side of the wringer-rolls. Each of the `levers is preferably 'provided with a rearwardly' extending portion 87 at a.` point n between 'the wringer-rolls, from which an upwardly extending portion 88 ex- This upwardly extending portion is preferablyin the vertical plane parallel with 4thewringe'rlrolls in which the shafts of the wringer-rolls are located.

This provides a compact construction, and provides of the levers and the upper cross-barv connecting the levers for movement thereof either forwardly or backwardly for the prevention of'accident. A pushing or pulling .upon the' cross-bar 79 yor theA exposed portion-of either of the levers 71 causes pressure of one vof the lugs 82, 83,

move the'spring latches for releasing the upper' frame-section, and when' the upper "'crossfb'an) is'inoved rearwardly `by the ff'operator, the'lower lugs 83 move' the spring ilatches 'for releasing the upper-frame-section. This movement of thereleasing' means 1s readily' accomplished by the operator by mere pushinor or pulling contact withv the upper ends e? the levers or cross-bar without the necessity convenient placing of the upper ends at each end of the machine against the sprii'ig'latchesfor instantly releasing `said `spring latches by a short movement of the of grasping any of these 'parts by thehand. y f I The pressure between the` wringer-rolls may be adjusted by adjusting the adjusting screws 34 and thereby adjusting the bearings of the upper wringer-roll in the'yokes 31 toward and awayfrom the lower wringer-roll.

The release movement of the upper wringer roll may be limited byl providing-the pivotlugs 49 with projections arranged to contact the pedestals 12,-w1hen the upper vwringer-rolly is swung rearwardly upon release of the latches 65.

My improvedl 4device is especiallyl simple and eifective for the purposes described, and is compact, economicall i-n construction' and durable; f'
