It is desirable to provide wringers with a comparatively quick 'tensioning devicexand a tensioning device which may be varied. It

is also desirable to provide in such a device a means by which the tension may be quickly released so that in case of accident the pressure may be released'to avoid injury to the operator. The present invention is designed to eflect a quick adjustment and a variation .10 ofthe adjustment aswelljas a quick release.

Features and details of the invention will appear from the specification andclaims.

A-preferred embodiment of the invention is illustrated in the accompanying drawings as I follows 7 Fig. 1 shows a front elevation of awringer, partly in section.

Fig. 2 a section on the line i22 in Fig. 1 showing theextreme adjustment.

Fig.8 a front view of the structure illustratedin Fig. 2. I 1 g Fig. 4 a view similar toFig. 3 with the smaller adjustment. H

Fig. 5 a view showing the parts in releas- Fig. 6 a section on the line 66 in Fig. 5. The wringer frame comprises a base-1, sidestiles 2and a top bar 3. Wringer rolls 4 arearranged in the usual bearings 5, the upper bearing being slidingly mounted-in the side stiles in the usual manner. A spring 6 rests on the top of the upper mountings. An adjustment fitting 7 is secured in the top bar 3. This has a cylindrical opening 8 "85 through it and radially extending slots 9.

Cam surfaces 10 arearranged on the bottom of the fitting 7 andare adapted to engage shoulders 11 on an adjusting and releasing member 12. This member extends through opening 8 and has a handle 18 preferably formed integrally with the, member 12.

A bottom member 14 rests on the spring and has the securing lips 15 which are bent over the under part of the spring, thus locking the member 14 with the spring. This member has an opening 16 through it terminatingin a-socket 17 at thelowerlend. "A bolt 18 extends through the opening'16 and 1s provided with a lieadl9 having some up and down play in thesocket17. The bolt 18 extends through themember 12' and the member is screw threaded receiving the threaded end of the bolt and a nut 20 is arranged-on the upper end. The bolt locks the diiferent members together with the spring.

The upper end of the member 14: lS provided with a cam surface 21 at one side. which "engages a cam surface 22 on the bottom of the member112.

Upon turning thehandle 13 the member 12 is turned, thus swinging the shoulders 11 on and off the cam surfaces 10. With the shoulders under the lower ends of the cams the spring is forced downwardly" and put under compression. If the movement of the han-' dle is in one direction, bringing the shoulders under the camslO it will also bring the cams .21 and 22 into register thereby separating the members 12 and Hand increasing the desired movement of the spring to the throw of the

cams

21 and 22. If, however, the handle is turned in the opposite direction in bringing the shouldersunder the cams 22, the

cams

21 and 22 are swung toopposite sides of the members, as indicated in Fig. 4,

j and under'these conditions thereis no separation of the

members

12 and 14 incident to the action of the

cams

21 and 22 and under these conditions there would be the single adjustment incident to the cams 10; In this way, either anincreased adjustment bringing in both the

cams

21 and 22 and the cam 10, or

10 may be had.

' 7 The shoulders 11 are adapted to pass through the slots 9 so that when the handle is turned bringing the shoulders 11 into register with the slots 9 if there is a real pressure on the rolls. themember 12 is released upwardly through the fitting 7 the member 14 the single adjustment incident to the earns following into the opening in the fitting 7, thus giving a full range of release movement. It is desirable, however, to prevent the violent up-throw of the member 12 under the action of the spring and the bolt 18 ties the parts together so as to prevent this. Further it holds the spring and top bar in assembly so that the top bar may be made removable, if desired, without carrying with it the spring assembly.

WVhat I claim as new is 2- 1. In a wringer, the combination with frame, a pair of rolls mounted therein, and a pressure device for the rolls, of a rotatable member mounted in the frame; means cooperating with the member moving the member longitudinally to put pressure on the pressure device with a rotational movement of the member; meanslocking the member in said pressure adjustment; mechanism exerting additional pressure on the pressure device upon another rotational movement of the member; and means locking the mechanism with said additional pressure adjustment.

2. In a wringer, the combination with a frame, a pair of rolls mounted therein, and a pressure device for the rolls, of a rotatable member mounted in the frame; means cooperating with the member moving the member longitudinally to put pressure on the pressure device with a rotational movement of the member; means looking the member in said pressure adjustment mechanism exerting additional pressure on the pressure device upon another rotational movement of the member, said means and mechanism operating cumulatively upon the spring; and means locking the mechanism with said additional pressure adjustment.

3. In a wringer, the combination of a frame having a top'bar; a pair of rolls mounted therein; a pressure device operating upon the rolls; a rotatable member mounted in the frame; a cam-mechanism between the top bar and the pressure device comprising a cam between the rotatable member and the frame moving the rotatable member longitudinally with a rotation of the member; a bottom member; and a cam between the rotatable member and the bottom member adapted to add pressure to the pressure device upon a rotation of the rotatable member.

l. In a wringer, the combination of a frame; a pair of rolls mounted therein; a pressure device operating upon the rolls; a rotatable member mounted in the frame; a cam between the rotatable member and the frame moving the rotatable member longitudinally with a rotation of the member; a bottom member actuating the pressure device; and a cam between the rotatable member and the bottom member adapted to add pressure to the pressure device upon a rotation of the rotatable member, said cams being faced to operate cumulatively, or individually, depending on the direction of rotation of the intermediate member.

5. In a wringer, the combination with a frame, a pair of rolls mounted therein and a pressure device for the rolls, of a rotatable member mounted in the frame; means cooperating with the member moving the member longitudinally to put pressure on the pressure device with a rotational movement of the member; means locking the member in said pressure adjustment; mechanism exerting additional pressure on the pressure device upon another rotational movement of the member; and means locking the rotatable member with said additional pressure adjustment; and means releasing the rotatable member relieving the pressure of the pressure device with a given location of the member relatively to the frame.

6. In a wringer, the combination of a frame having a top bar; a pair of rolls mounted therein; a pressure device operating upon the rolls; a rotatable member mounted in the frame; a cam mechanism between the top bar and the pressure device comprising a cam between the rotatable member and the frame moving the rotatable member longitudinally with a rotation of the member; a bottom member actuating the pressure device; a cam between the rotatable member and the bottom member adapted to add pressure to the pressure device upon a rotation of the rotatable member; and means releasing the rotatable member relieving the pressure on the pressure device with a given position of the rotatable member.

7. In a wringer, the combination of a frame having a top bar; a pair of rolls mounted therein; a pressure device below the top bar operating on the rolls; a member rotatably mounted in the top bar; a member mounted on the pressure device; cams between the pressure device and the rotatable member for putting the pressure device under pressure with a rotation of the rotatable member; and means for releasing the member for movement longitudinally with respect to the frame with a given rotation of the member relatively to the frame and to release the pressure device. 1

8. In a wringer, the combination of a frame having a top bar; rolls mounted therein; a spring below the top bar operating on the rolls a cam member rotatably mounted on the wringer frame; a cam between the cam member and the frame; a bottom member secured to the spring; and a cam between the bottom member and the cam member.

9. In a wringer, the combination of a frame having a top bar; rolls mounted therein; a spring below the top bar operating on the rolls; a cam member rotatablymounted on the wringer frame; a cam between the cam member and the frame; a bottom member secured to the spring; a, cam between the bottom member and the cam member; and a shoulder and slot connection between the cam member and the frame adapted to release the cam member when the slot and shoulder are brought into register to relieve the pressure on the spring.

In testimony whereof I have hereunto set my hand.
