NETZEL, OF LAKEWOOD, ORTO, ASSGNGR TO AEELE MARY ORE, OF CLEVE- LANB, OHIO, AND THE CLEVELAND TRUST COMPANY, OF CLEVELAND, OHO, A CORPORATION OF OHIO, EXECUTORS OF WILLIAM URB, DECEASED WRINGER Application nled August 12, 1931.

My invention relates to machines and apparatus, which may be more particularly adapted for wringing clothes, and which may include Atwo longitudinally extending rolls, releasable means for pressing the rolls against each other, the longitudinal axes of the rolls being preferably parallel, and 'means for releasing the pressure applying means.

In the case of clothes wringers, the rolls are frequently made of rubber and it is desirable 'to release the pressure of one roller upon the other when the wringer is not in use.

Moreover in the case of power driven wringers, particularly for household use, it `is practically essential that means be provided for quickly releasing the pressure between the rolls, and it is desirable that the releasling means may be operated by involuntary action of the user, so that in the event that the users fingers are caught between the rolls.y the pressure between the rolls may be released before serious injury has been inflicted.

My invention furthermore relates to the structure and arrangement of the bearings for the wringer rolls, to the power` drive for he rolls, to automatically reversing` drain boards, and to feed boards for wringers and the like.

The objects of the present improvements include the provision of simple and efficient means for yieldingly pressing wringer rolls and the like against each other combined with positive means substantially instantaneously operative by a single action on the part of the user to release the pressure applying m-eans. u

Further objects of the improvements 1n- Vclude :the provision of a simplified and easily manufactured structure and arrangement of the bearings for the wringer rolls and of the power drive for the rolls.

Further objects of the improvements include the provision of a wringer having a simpli'lied and effective automatically reversing drain board.

Further objects of the improvements includel the provision of a wringer having an lerial No. 556,537.

improved and simplified structure and arrangement of the feed boards therefor.

The foregoingand other objects are attained by the wringer, apparatus7 parts, improvements and combinations, which comprise the present invention and which are particularly and distinctly pointed out and set forth in the appended claims formingpart hereof.

ln general terms, the improved wringer of the present invention may be described as including a frame, a normally lower roll and a normally upper roll, means journaling the lower roll in the frame, bearing bloclrs jour naling the upper roll, means mounting the bearing blocks in the frame for sliding towards and away from the lower roll, a head, preferably yielding means located at one side of the rolls and mounting th-e head for pivoting about a normally horizontal axis, means on the head adapted for abutment against the bearing blocks for the upper roll for pressing the upper roll against the lower roll, hook means, means located on the frame atthe other side of the rolls and preferably yieldingly mounting the hook means for pivoting about a normally horizontal axis, shaft means rotatably mounted on the head, hook engaging means mounted on the shaft means for selectively engaging the hook means by rotation of the shaft means for applying pressure to the rolls, means mounted on the shaft means for positively displacing the hook means from the engaging means by further rotation of the shaft means, and a lever for rotating the shaft means.

rlhe improve-d wringer furthermore includes reversible bearing blocks for the upper roll, one reversible bearing block for one end of the lower roll, and an easily separable bearing and drive connection for the other end of the lower roll.

rlhe improved wringer furthermore includes a drain board pivot-ally mounted on the frame below the normally lower roll, the lower roll including a shaft, preferably split collar means frictionally mounted on the lowcr roll shaft, and means providing an operative connection between the frictionally mounted collar means and the drain board for reversing the inclination of the drainboard when the direction of rotation of the rolls is reversed.

The improved wringer furthermore includes a formed metal feed board located at each side of the rolls, and each feed board including a hanger pin extending from each end thereof, and the frame having formed therein preferably upward and oppositely opening slotted shoulders, each shoulder being adapted for removably supporting one of the hanger pins.

The opposite faces 22'@ and 23a of the walls 22a and 23a, respectively, comprise npwardly opening vertical bearing block guideways in the housing and supporting member 15a and the lower ends of the walls 22a and 23a merge with the upper ends of a segmental cylindric bearing mounting wall 24a extending between the walls 16a and 17 a, and the upper and central portions of the wall 16a terminate and merge with edges of the walls 22a, 23a, and 24a. The housing and supporting member 15b includes longitudinally spaced laterally and vertically extending walls 1Gb and 17h and laterally spaced longitudinally and vertically extending walls 187) and 19?). The walls .165 and 17o merge at their vertically extending edges with the walls 18D and 19t to form a vertically extending housing chamber 20?) which is open at its lower en-d.

The housing and supporting member 15b also includes an upper normally horizontal wall 21-1?) merging at its edges with the upper edges of the walls 167), 187), and 17?), and with the upper end of a normally vertical wall 22() extending longitudinally between the walls 166 and 17?), and thel wall 220 is laterally spaced from one side of the median plane M.

The housing and supporting member 15?/ wall 235 extending longitudinally between the walls 166 and 17 b, and the wall 23?) is lat- 'l' are located so thatthe head 50 may be swung towards and away from the upper roll 41-2 about a horizontal longitudinally extending axis 52-1 at one side of the rolls 411 and Means are provided on each end of the head 50 for abutment against the upper end faces of the bearing blocks 47 journaling the upper roll 41-2 for pressing the upper roll 41-2 against the lower roll 41-1; and in the illustrated embodiment of the invention, the head abutment means include shoulders 53a and 536 located at the opposite ends of the head 50, and adapted for abutment toward and away from the upper roll 41--2 so that the normally lower faces 53'@ and 536 of the shoulders 53a and 536 respectively abut against the upper end faces of the bearingr blocks 47 for the upper roll 41-2.

The head 50 is of suiticient width laterally to extend across the upper roll 41--2 from the yielding pivotal mounting of the head 50 at one side of the rolls to the other side of the rolls.

Catch means, preferably hook means 54a and 546 are located at the side of the rolls opposite to that of the yielding pivotal mounting means 51-a and 51-6, and means indicated generally by 55a, and 556, respectively, yieldingly and pivotally mount the hook means 54a and 546 on the frame for swinging about a normally horizontal axis 52-2 located on the opposite side of the rolls to that of the axis 52-1 about which the head 50 swings.

Hook engaging means indicated generally by 56a and 566 are movably mounted on the head 50 for selective engagement respectively with the hook means 54a and 546, and hook displacing means 57a and 576 are movably mounted on the head 50 for positively displacing the hook means 54a and 546 for engagement thereof with the engaging means 560J and 566.

The engaging means 56a and the displacing means 57a preferably comprise cam members extending in different directions and secured to a stub shaft 58a, which is journaled in the head 50, and similarly, the engaging means 566 and the displacing means 576 preferably comprise cam members extending in different directions and secured to a stub shaft 586 which is journaled in the head 50.

As illustrated, the engaging cam member 56a and a displacing cam member 57a are located at one end of a longitudinally and laterally extending lever 59, and the engaging cam member 56a and the displacing cam member 57a are similarly located on the other end of the lever 59.

The hook means 54a includes 'a catch head 60a which extends towards the rolls for engagement by the engaging cam member 560.; and the hook means 546 is similarly arranged.

The yielding and pivoting means 55a, by

which the hook means 54a is mounted on the frame 11, includes a normally vertical shaft 61a slidably extending through a bore formed in the upper wall 21-2a of the housing and supporting member 15a.

The lower end 62a of the hook means 54a is pivotally connected with the upper end 63a. of the shaft 61a, above the wall 21-2a, as by means of a pin 64a extending through suitable apertures formed in the hook means lower end 62a, and in the shaft upper end 63a; and below the wall 212a a compression spring 65a is interposed between the lower face .Q1-2@ of the wall .Q1-2a and the upper face 66'@ of a washer 66a adjustably positioned on the shaft 61a as by means of a bolt 67a screwed on the threaded lower end 68a of the shaft 61a.

The yielding and pivoting means 556, and 51a and 516 are similar in detail to the means 55a.

In other words, by the construction and arrangement described in detail by the foregoing, the wringer 10 is provided with improved substantially instantaneously releasable means applying pressure between the rolls 42-1 and 42-2 of the wringer l0, and which operates as follows:

Fig. 6 illustrates the relative positions of the parts of the wringer after the head 50 has been swung downwardly over the upper roll 41-2, with the shoulders 53a and 536 abutting the upper bearing blocks 47, and the lever 59 rotated to its position of extreme displacement with respect to the head 50, positioning the engaging cam members 56a and 566 for being engaged by the hook means 54a and 546, respectively; and the hook means having been sprung back and snapped over the engaging members.

Rotation of the lever 59 towards the head 50, to the position illustrated best in Fig. 4, serves to clamp the rolls against each other, and place the wringer in position for use.

If the rolls become clogged in use, or the operators fingers become caught between the rolls, a single downward blow on the lever 59 serves to rotate the displacing cam members 57a and 57 6 against the hook means 54a and 546, whereby the hook means are positively displaced from engagement with the members 56a and 566, respectively, and the head 50 springs free to the position illustrated in Fig. 5, with the pressure between the rolls released.

The wringer 10, furthermore includes an improved automatically reversing drain board indicated generally by 160, and which includes a longitudinally extending dra-in hoard member 161 whose upper surface 161 is preferably concaved and laterally symmetrical with respect to the vertically longitudinal median plane M.

The drain board member 161 is located below the lower roll 42-1 and above the frame base 12, and entends longitudinally between the frame end members 1566 and 15?).

Means are provided for mounting the drain ,Fg board member 161 for pivoting about a normally horizontal longitudinally extending anis located in the plane M, and the pivotal mounting means for the drain board member 161 may include pivot lugs 16266 and 162?) vw, depending from opposite ends of the drain in board member 161, and pivotally seating respectively in grooves 16366 and 16377 which are formed in the upper surface 12 of the frame base member 12. Ag Preferably split collar means 164 are located on the cylindric end 44-166 of the shaft 43-1 between the adjacent end of the rubber tube 42-1 and the oppositel end of the bearing member 26.

- A plurality of radially7 extending friction plugs 165 are interposed between the split collar 164 and the shaft end 44-166, and adjustableY bolt means 166 are provided for applying a variable tension on the outer ends A, 16466 and 1645 of the preferably hinged split 2' collar 164, thereby maintaining the frictional pressure between the shaft end 44-166 and the friction plugs 165, which are preferably seated in inwardly opening sockets formed in the inner surface of the split collar 164.

3'3" The collar 164 is operatively connected withV the drain board member 161, as by means of circumferentially spaced teeth 16766 and 1676 extending outwardly from one side i of the collar 164, and receiving therebetween the upper end 168 of an arm 169 secured to and extending upwardly from the drain board member 161.

Accordingly, when the rolls are rotating in the direction indicated by the arrows 7 0 1 and 70-2 in Fig'. 7, the drain board member 161 will be swung to one side to the position illustratedin Fig. 7 in which one side 16166 of the drain board member 161 is abutting against the upper surface 12 of the frame e base 12 on one side of the rolls, and the frictional pressure between the collar 164 and the shaft 41-166 is such that the rolls then continuously rotate in the direction of the arrows 7 O--1 and TO-2 by slipping of the shaft end 44-166 across the abutting ends of the friction plugs 165.

lVhen, however, the direction of rotation of the rolls is reversed, the frictional pressure on u. .the plugs 165 is sufficient to swing the collar 164 in the opposite direction until the other side 1615 of the drain beard member 161 strikes against the upper surface 12l of the base 12 on the other side of the rolls, whereby N the drain board member 161 is automatically i reversed to always slope downwardly below the lower roll 42-1 in the direction of rotation thereof.

For strengthening the frame 11 and at the same time forming on opposite sides of the rolls, drain troughs extending beyond the sides of the drain board member 161, the

frame 11 is preferably provided with webs 71-166 and 71-16 extending respectively between one side of the frame end member 1566 and the base 12, and between one side of the frame end member 15b and the base 12.

Similarly, webs 71-266 and 71-25 extend respectively between the other side of thc frame end member 1566 and the b-ase 12, and between the other side of the frame end member 15b and the base 12.

The wringer furthermore preferably in chicles formed metal feed boards 7 2 1 and 72-2 located on opposite sides of the rolls.

The feed board 72-1 is located on one side of the rolls, and includes hanger pins 73-166 and T3-1b extending respectively from op posite ends of the feed board, and the pin 7S-166 is removably supported at the base of an upwardly opening slotted shoulder 7 4-166 which is formed in the upper end of the frame end member 1566; and the pin 73-16 is similarly removably supported at the base of an upwardly opening slotted shoulder formed in the upper end of the frame end member b.

The other feed board 72-2 is similarly constructed and removably supported at the other side of the rolls.
