' UNITED STATES N. A. RHOADSgOF WATERBURY, VERMONT.

IMPROVED CLOTH ES-WRINGER.

Specification forming part of Letters Patent No. 34,646, dated March 11,1862.

To all 'whom it. may concern: 1

Beitknown that I, N. A. RHoADs, of Waterbury, in the county of Washington and State of Vermont, have invented certain new and useful Improvements in Clothes Wringersg and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in

Figure l is a longitudinal section through the machine, taken in the vertical plane indicated by the red line z zin Fig. 3. Fig. 2 is la horizontal section through Fig. 3, as indicated by the red line :c 0c thereon. Fig. 3 is a transverse section through Fig. 1, taken in the vertical plane indicated by red line y y thereon.

and use my invention, I will proceed to describe its construction and operation.

Y A A represent two uprights, which are braced together by transverse rods a ct a., so`

as to form al strong quadrangular frame for containing and supporting the wringing and clamping apparatuses. Y

B B are two iron shafts, which have their bearings in journal-boxes h Z) c c. One end of shaft B passes through a vertical slot d, made through one of the uprights and receives on its end a hand-crank C, by means of which .this shaft B is turned in operating the machine. f The journal-boxes b b c c are let into vertical grooves e c, in which grooves these boxes are allowed to have a free vertical play, so that the shaft B while preserving its parallelism with shaft B, may at the same time be moved farther from this shaft as occasion requires. The shaft B is made with grooves, ribs, serrations, or longitudinal projections of any suitable description on its surface, and

on this surface a rubber roller D is formed in the usual manner of putting rubber rollers on shafts. The india-rubber being put on such a shaft, it will be readily seen that all liability of this rubber working loose on the shaft is eectually prevented. Arubberroller D surrounds the upper shaftB,which may be of the same or of a greater diameter than the lower roller D, and this latter roller D may be put on a shaft constructed, as described, for the lower roller; but as this upper roller D is less liable to'become loose on its shaft than the roller D the shaft B may have a smooth surface. The proper construction of these two indiarubber rollers is important, and it is desired to so construct them that the articles which are passed between them should be squeezed uniformly, whether there be a greater or less bulk inthe middle than at the ends of these rollers. For this purpose the surfaces of the two rubber rollers D and D taper from their ends to their middle, so that they are smaller in diameter in the middle than at their ends, as shown in Figs. l and 3 ofthe drawings. The peripheries of these two rollers D D will thus touch each other at and near their ends; but a space will be left between the two rollers D D at and near the f middle thereof, through which the greatest bulk of articles will pass as they are submitted to the action of the rollers. Theends of the upper roller D rest on the ends of the lower roller, and the upperroller, with its shaft B', is rotated in its bearings bythe rolling friction of the lower roller.

India-rubber springs g g are placedon the boxes b h ingrooves e e, and on these blocks of rubber g g the ends of a transversev bar G rest. Above this transverse bar G a shaft H is arranged, having its upward bearings against the stationary blocks h h. This shaft Il is furnished with a lever or handle la, Aand. on each end of the shaft is a cam-shaped enlargement Z, as shown in Figs. l and 3 of the drawings. Cams ZZ are faced with metal, and

the ends of the bar G are also faced with metal, as represented in Fig. 1. These cams Z Z are used to increase or to diminish the pressure on the articles passed between the rollers D D', and also to allow large or small articles to be passed between these rollers D D, and to give the required pressure to either. The required pressure on the articles is 0btained almost instantly by raising or depress:

ing the handle la, which operation rocks the cam-shaft H and brings the cams Z l in the desired position, and while the articles are passing between the rollers D D thepressure can be regulated as the articles increase or diminish in bulk. p

It will be understood that the cams Z Z do not lift the upper roller D. This roller is raised by the articles passed between. the rollers when the cams Z Z are in such a position as will allow the journal-boxes b b to rise.

An important advantageA results from the employment and particular arrangement of the bar G, with reference to thefsp'rings g g, the canisl Z, and the shaft H, and leve-r or handle la, as the said bar' by suclr not only becomes useful as a stop for the handle' and asa bearingA for. the can1s-,but it servesto so connect the two springs as to prevent either from crippling orbending laterally, aswell asbeing thrown out-oi? place under theupward pressure; of. the rollerejpurnal under it. p B'esides",i-t enables the journals of the shaizr'ty to be arrangedl directly over thesprings, Arespectiyelm and' tor have theA car-ns` placedi next to and betweenL suchjournals.V
