WILLIAM T. MGMILLEN, OF CINCINNATI, OHIO, AND EDWARD P. CONRICK, OE DUBUQUE, IOWA,.AS SIGNORS, BY MESNE ASSIGNMENTS, TO THE METROPOLITAN WASHING MACHINE COMPANY.-

@ IMPROVEMENT IN c'LoTHEs-wRmGERs.

Specification forming part of Letters Iatent No. 56,591, dated July 24, 1866 reissue No. 7.365, dated October 24, 1876; application filed September 12, 1875.

To all whom it may concern v -Be it known that we, WILLIAM T. MoMIL-- LEN, of Cincinnati, Hamilton county, State of Ohio, and EDWARD P. GoNaIoK, of Dubuque, Iowa, have invented certain new and useful Improvements in Olothes- Wringing Machines; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being-had to the accompanyingdrawings, making part of this specification.

We have devised means for gearing the rollers in such a manner as to give an increase I of leverage for the operator,'and to relieve the rolls of the greater part of the twisting strain common to this class of machines. Also for arranging movable bearings so that the driving-pinion and its connecting-gear will always remain in the same relative position to eachother.

In the accompanying drawings, Figure 1 is a perspective view of a clothes-wringerembodying our invention. Fig. 2 is a modifica- Aand B are respectively the upper and lower rolls of the wringer, geared together at both ends by pinio'ifs G O and DD, and operated by connection at both ends with the pinions E-E on the counter-shaft F. The shaft F is operated by the ordinary handle G. The rolls I and counter-shaft are journaled in suitable housings, H H, which are provided with slides I 1, on; which the boxes J J slide. K K are rubber springs, kept in place by straps and bolts M M N.

We have ascertained by careful experiments, that by gearing the rolls at both ends they can be operated with much greater ease, and with little twisting strain of the gum on the In the wringer-machines now in use the ter- .sion of the gum is so great that the roller to which thepower is applied is so mueh twisted as to shortly become loose on the-shaft, and

of course ,useless- As the gum rollers are much the most expensive parts of the machinatheir durability is quite an object. By the use of the counter-shaft 'F and the heavy articles, such asbed-quilts, can be run A through themachine with great ease.

In the modification, Fig. 2,-an additional pinion, O, is secured to the shaft of the roller A, and meshes into a suitable pinion on the counter-shaft F. By this device a still greater leverage can be obtained over the rollers, as

the wheel 0 can be of larger diameter than the pinions of the rollers.

Though the device as exhibited in Fig. 1 is t the preferred type of 611: invention, we do not desire to restrict ourselves to this precise form.

A modification may be made by gearing the rollers together, and with the counter-shaft at one end'only.

The term fupper roll is here used to describe the roll which moves to and from its mate, whether it be directly above or in variously-modified positions.

We claim herein as new and of our invention- 1. The combination, in a clothes-Wringer with elastic-rubber rolls,of a purchase driving pinion, either at one or both ends of the mechanism, supported in bearin gs, arranged to rise andfall vertically with the upward and downward motion of the movable roll.

2. The combination', in a clothes-wringer having elastic-rubber rolls, of a purchase pinion at one end, mounted on a hearing or bearings moving vertically with the movable roll, and meshing into and driving a cog-wheel of larger size'fixed to the shaft of the Inovable roll.

, A In. testimony whereof we have hereunto set Olll names.
