IMPROVEMENT IN CLOTHES-WRINGERS.

Specification forming part of Letters Patent No. 156,585, dated November 3, 1874 application filed July 29,1874.

To all whom it may concern:

Be it known that I, THOMAS E. MCDONALD, of New Brunswick, in the county of Middlesex, in the State of New Jersey, have made certain Improvements in Glothes-Wringers, of which the following is the specification:

The object of this invention is to cheapen the construction of wringers, and to do away or dispense with many parts that have heretofore been considered necessary in their construction, without inany way impairing their strength, durability, or usefulness; and it consists in the construction of some of the posts that support the rolls, and the relative arrangements of the said rolls with the new construction of the posts,'as will be fully hereinafter described.

In the drawings, Figure 1 represents a side view of the wringer; Fig. 2, an edge or end view; and Fig. 3, a modification of what is seen in Fig. 2.

A represents a supporting-post at each end of the wringer-rolls, madefrom a single piece of wood. A A are tie-girts to secure the tops of the two end posts in position by means of screw-bolts a a. i A is the usual clamp at the bottom of the Wringer to fasten the same to the tub or vessel. B is the lower roll on journals b, working in bearin gs in posts A. At one end the journal 12 projects to receive the crank that is used to turn the rolls. B is the upper roll on journals b, working in bearings in posts A. G is a transverse guidepiece on the entering side of the wringer, and held fast upon the posts A by screws 0 c, which also serve to hold the post A in position. D is a strengthening-girt on the delivery side, and secured to the posts A by the screw-bolts of clamps A" and screws cl. A isa reverse curved slit in the posts A, as seen in Fig. 2, dividing the posts in two parts for a distancepart marked 1 carries roll B, and part marked 2 carries roller B-the purpose and effect of which is to give the proper elasticity to the rolls in passing articles through between thetn by forcing the two parts of the posts, made by the slit, apart to allow any difference of thickness in such articles to easily pass, and still to act-as a means to return the rolls together when no clothes are between them. This curved slit can be made as seen in either Fig. 2 or 3, as may be desired.

In this construction of the supporting-posts and the journaling the rolls in the two parts, separated by the curved slit, all the elasticity required is given the rolls, thus doing away with the expense of springs and temper-screws to regulate 'the pressure of the wringer-rolls upon the clothes passing between them.

What I claim is- 1. The posts A of a clothes-wringer, provided with slits A", as described, whereby the posts are divided a portion of their length, and by such division one part is yielding and can be forced away from the other, and when such force is removed the parts will assume their normal position.

2. The post A having slit A", in combination with the roller B on one side of the slit, and roller B on the opposite side of said slit, substantially as and for the purposes described.
