This invention relates to `wringers as de-l scribed in the present specification and illustrated in the accompanying drawings which form part of the same. v

The invention consists essentially of the novel features pointed out broadly'l and specifically in the claims for novelty following adescription containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to provide a wringer having means for regulating and indicating the pressure upon the v rollers; t-o produce astrong and dependable wringer, easily operated, and positive of action; and generally,

' serviceable machine that will accomplish the l to'the shaft 17 'ings encased in aforesaid purposes.

In the drawings, Figure 1 is a sectional sideY view through the center line of the wringer, showing parts in elevation.

Figure 2 vis a plan view, showing the spring housing in section. Y

Figure 3 is a sectional view at right angles 25 to the axis ofthe rollers, showing the rollers removed from their shafts.

Figure 4 is a sectional view showlng the trip mechanism for releasing the tenslon in theroller spring,and various of its worliing parts. y i e numerals of reference indlcate cor-` respondin parts in the various figures.

The bo y orcasing of the wringer consists of two end portions 10 and 11 rigidly secured together by means of a plate 12 l riveted thereto. The vportionll is ada ted at the bottom to be mounted upon, .an rotate on, a tubular shaft of a washing machne,or some other post or sha-ft.

13 is the lower roller a shaft 14. One end of the .shaft rotates in ball bearings encased in'portion 10 of the body; the other end is squared and fits into the sleeve of the gear 15.

16 is the upper roller, mounted vertically above the lower roller. It is rigidly secured which rotates 1n ball bearthe rock arms 18 and 19. The rollers have different diameters, preferably in the ratio of 3 to 2, in order to more A easily feed the 'material through the rollers.

Upon the shafts 14 and 17 are rigidly mounted at one end, the spur wheels 20 and"A 21, respectively. lThe spurs 20 and 21 are Vto supply a most rigidly mounted on is held in its o upon never in'engagement, and the rotation of the spur 2O is transmitted to the spur 21 through the agency of the two spurs 22 and 23, which are suitably mounted on the portion 11 of the b'ody. These spurs have the same diameter as the spury 21, and the diameters of" 20 and 21 must bear the same ratio one to the other, as the diameter of the roller 13 bears to that of the roller` 16. v

24 is a tubular shaft rotatably mounted in the casing of the wringer and the rock arms 18 and 19 are pivotally mounted upon the shaft 24.' It will be seen, that the top roller 16 is free to automatically rise and fall as the material passes between the rollers.

A helical spring 25 encircles the shaft 24, andis enclosed 1n the spring housing 26. The collar 27 is rigidly mounted in the inside of the spring housing 26` by means of a pin 28. The spring 25 is suitably secured to the collar 27, and rections on each side of the said collar. The ends of the spring have portions extending out and bearing upon the rock arms 18 and 19. This allows the rock arms 18 and 19 to rise orplower independently of one another; also the ends of the shaft 17, and therefore of the roller 16, are free to rise or lower independently of one another.

The gear 29`is rotatably mounted on` the shaft 24. i It has notches 30 adapted to be engaged by the fingers 31 of the plunger 32. The plunger'32 has an enlarged end portion 33 bearing in the inside' of the shaft 24. Notches 34 are also provided in the shaft 24 to receive in engagement the fingers 31. When the plunger is in its o erative position, as shown 1n Figure 4, t e fingers 31 engage the notches 30 and 34. The plunger erative position-h7 means of the spring 35 earing at one en u on the portion 11 of the body, and at the ot f er end, the portion 33 of the plunger. The shaft 24 extends some ortion 11, and the ngers 3l are always 1n engagement with the notches 34. As the fingers are beveled off at their ends, the notches 30 of the gear 29 will be easily engaged upon the rotation of the crank 38A.

When the plunger is in its operative position, any rotation of the gear 29 will cause "the shaft 24 to rotate and therefore wind distance into the lll() spring pressure upon the rock arms 18 and 19, and therefore, the pressure upon the roller 16, will be increased accordingly.

A lever 36 pivots upon the body and has.

one' end aadpted to receive the head 37 in the plun er. When the lever is forced downwar y, the plunger is pulled out of engagement with the gear 29, and the sprlng unwinds itself. 4 A pintle 38, operated by a crank 38 1s suitably mounted upon the body, and r1 1dly mounts a worm 39 at the bottom. e worm 39 engagesthe gear 29 by which the 25 is wound.

The portion 11 of the body 1s adapted to enclose the shaft of a washing machine` or other drive shaft. A demountable bearing bracket 40 is suitably secured to the portlon 11 and is adapted to rotatably mount the said shaft. 41 and 42 are gears adapted to be rigidly mounted upon the said shaft and so positioned thereupon to be held from engagement with, or to alternatively engage, the bevel gear 15.

A circular block 43 is provided in the upper part of the portion 11 and is adapted to be loosely mounted upon the shaft of a washing machine or on the other drlve shaft reviously 'referred to. The top of the block 1s recessed to receive the washer 44 upon which the said drive shaft is supported.

A cap 45 pivotally mounting a handle 46 fits upon the upper part of the portion 11, and is held thereto by means of a set screw 47 engaging a groove 46A in said upper part;

' the set screw 47 projects into the block 43.

The groove is so formed that when the set screw'travels from one end to 'the other ofsaid groove, the block 43, and therefore the shaft mounting the gears 41 and 42, will assume three separate positions. The two extreme positions determine the direction of rotation of the rollers while the intermediate or neutral position, retains the rollers idle.

A graduated dial 8O is rigidly secured to the tubular shaft 24 by means of the pin 81; an index pointer 82, rigidly secured to the portion 10 of the casing projects over the dial. The dial is so graduated and adjusted upon the shaft 24, that when all pressure is released in the spring 25, the pointer is directly above the zero mark, and the pin 81 so disposed on the shaft that it will bear against the index pointer 82. The shaft can then only be rotated through less than 360 degrees as/the pin will finally engage the pointer, the 'resiliency possible of imparting to the spring being, therefore, limited. A
