IMPRovEo CLOTH Es- WRINGER- Specification forming part of Letters Patent No. 33,!61, dated December 3, 1861.

To all whom it may concern:

Be it known that I, WASHINGTON WHITNEY, of Baldwinsville, in thecounty of lVorcester and Stateof Massachusetts, have invented an Improved Clothes-'-ringing Machine, of

which the following is a full, clear, and exact description,y reference being had to the accompanymg drawings, making part of thisspecicatlon, irr which- 'Figure lis a view of my improved machine;A

Fig. 2, a partial end View of the same enargedfwith one of the springs removed.

Myinvention consists in an improved manner of hanging one of the rolls of a clothesagainst the inner edge of the tub. Small projections 5 and 6, cast on the edge of the leg a, help to give it a better hold on the surface of the wood with which it comes in contact.

The shaft of the lower roll Il has its bearings at c in the two end frames, and the shaft (l of the upper roll Chas its bearings in two stout arms D, the other ends of which are pivoted at e to the-end frames A A. The pivot y von which these armsD are hung is acoupling rod or brace E, which. couples the two endframe's together. The rod-is turned down,

forming a shoulder at' each end, just inside of the arms D, and passes through the two end frames, and has a pin 7 driven through each of its ends. AcrankvF and handle f are attached to the end of the` shaft d, which. is I prolonged to a convenient length. 4(The draw-- ings show the shaftf'lshorter than I generally make it.)

To the outer end of the arm D is attached a' disk g, with a hole through its center, through which plays a rod h, the lower end of which is hinged at S to a short arm l', project-ing from the end frame A.

A cylindrical india rubber spring G is slipped overthe rod h and rests on the disk g. A` washer 9 is placed over the spring, and a thumb-screw 7, which screws onto the end of the rod h, serves to compress the spring and regulate the pressure of the rolls Bland C..

There is a similar arrangement of rod and 'spring at theother end of the machine.

The rolls B and C are covered with vulcan-I ized india-rubber in a manner common to y many of these machines.

Asthe articles to be squeezed are passed between the rolls B and C the latter roll rises against the resistance of the springstG,-the arms D vibrating` on their pivots e. As the arms D move, it is necessary that the rods It should also vibrate on their pivots 8, to permit'the springs G to` follow the motions of the arms D. v

The construction of this machine permits a considerable up-and-down motion-to the roll C, without the necessity of a cumbersome frame-work above it to contain the springs which hold it down.

XVhat I claim as my invention, and desire to secure by Letters Patent, is-

The within -desc'ribed Wringngmachine,4

having its rolls B and C drawn together by the spring G, which is pivoted at-one end tothe frame and is compressed by an attachment g to the upper, as set forth, for the purpose specified.
