IMPRVEMEANT IN CLOTHES-WRINGERS.

Specification forming part of Letters Patent No. 139,200, dated May 20, 1873; application tiled January 8, 1873. p

To all whom it may concern:

Be it known that I, HAMILTON E. SMITH, of Fitchburg, in the county ofWorcester and in the State of Massachusetts, have invented a new and useful Improvement in Glothes-Wringers 5 and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specilication, in which drawing- Figure 1 represents a sectional front view of this invention. Fig. 2 is a transverse section ofthe same in the planemm, Fig. 1. Fig. 3 is a similar section of the same in the plane y y. Fig- 1- Similar letters indicate corresponding parts.

This invention relates to an improvement on that class of clothes-wringers which I have i described in a patent granted to me May 30,

1871, N o. 115,372, and in which a loose,lexible, or elastic roller is combined with a series of rigid rollers connected to each other by gearwheels, whereby alll said rigid rollers receive a positive motion. A

My present improvement consists in applying the driving-power to the intermediate gear-wheel, which meshes in the gear-wheels mountedon the gudgeons of the rigid rollers, the axle of said intermediate gear-wheel being supported on the outside of the Wheel by a cap, which is secured to the frame of the wringer in such a mannar that said axle is rmly sustained in position, and that the motion of the machine is rendered uniform and comparatively easy.

In the drawing, the letter A designates side frames or standards, which are connected by cross-ties m m, and provided with screwclamps for the purpose of securing the same Said screw-clamps are connected `to the side frames by means of hinge-joints, (see Fig. 2,) so as to facilitate the operation of adjusting the wringer in the required position, and to allow the same to adapt themselves to the curvature of a tub or vessel to which the wrin ger is to be clamped. The side frames A Al form the bearings for three rigid rollers C C1 G2, between which is situated a loose, iiexible, or elastic roller, B, as shown in Fig. 2. The flexible roller B runs lloosely between the rigid rollers, C (l1 G2, and

the axles of said rigid rollers extend through one of the side frames, and on their outer ends are mounted cog-wheels c c1 c2, all of which gear into an intermediate gear-wheel, b, which is mounted on an` axle, d. One end of this axle has its bearing in the side frame A and its other end is journalcd in a cap, F, which is secured to the outside of said side frame and encloses all the gear-wheels. The axle d extends beyond this cap, and on its outer end is secured a hand-crank, E, or any other device for turning the cog-wheel b, and as this cog-wheel is turned motion is transmitted to the rollers C Cl O2 and also to the flexible roller B, which revolves by frictional contact with the rigid rollers. The journalboxes of the top roller C are fitted into guideslots on the standards and exposed to the action of set-screws f, so that the pressure exerted by the rigid rollers on the iiexible roller can be increased or diminished at pleas-` The power being applied directly to the y ure. intermediate gear-wheel b is uniformly distributed to the several workin g parts, and neither of said parts is subjected to an undue or unequal strain and, furthermore, the i pressure exerted by the rigid rollers on the iexible roller can be more readily adjusted Vthan it can if the power is applied tothe axle of one of the rigid rollers; and, furthermore, by applying the cap F, I give a strong and durable support to the axle of the intermediate gearwheel b, and the strength and working capacity of my wringer is materially increased.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a wringer composed of a liexible roller, B, rigid rollers C C1 G2, and gear-wheels ccl c b, the arrangement of a hand-crank, pulley or other equivalent device on the axle of the intermediate gear-wheel b, substantially as and for the purpose set forth.

2. The cap F in combination with the axle d. of the intermediate gear-wheel b, and with the gear-wheels c c1 c, rigid rollers C G1 C, and exi ble roller B, all constructed and operatin g substantially in the manner described.
