IMPROVED WASHING-'MACHINEl Specification forming part of Letters Patent N0. 39,3413, dated July Q8, 1563.

INashing- Machine;` and 1" do hereby declare that'the following is afull, clear, and exact V'description thereof, reference being hadto the accompanying dra-Win gs, making a part of this specilication, in which n Figure 1 is a vertical longitudinal section taken through the` center of my improved maf chine. Fig. 2 is -a top view of the machine.' Fig. 3 is a'plan view ot' the vibrating rubbing. rollers. Fig.'4 is a faceY view of the washboard; and Figs. 5 and 6 show, respectively, atransverse and alougitudinal section through Fig. 5.

Similar letters of reference indicate corresponding part-s inthe several figures.

This invention relates to certain new and useful improvements on the machine secured to me by Let-ters Patent bearing date May 4, 1858.

The object of my present invention is to more effectually prevent the articles beiug'washed from working out at the ends of the rubbingrollers and causing the machine to work hard and imperfectly, and at the same time to pre- .veut any undue straining of the articles..

It also-has for its object ei'ecting an economy of soap by subjecting the articles to much stronger soapsud's while they are being rubbed than is contained in the body of the wash-tub, all as will be hereinafter described and represented.

To enable others skilled in the art to make and use. my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, A represents the wash-box, which is constructed with verti-r cal longitudinal sides and inclined ends, and a ledge, a, surrounding the upper edge at one end of the box, as shown 'in Fig. 2. This box A is mounted on legs B B, and has two upright standards, C C, affixed to the sides, which project yup some distance above the box, and receive in their ends groovcd bearing-boxes b b, which are mounted on springs c c, and receive and support thetranslverse rock-shaft D, which supports the rubbing-rollers d d d. The ends of the rock-shaft D project out from the outside ot' each block baud receive the ends of connecting-rods e c,

which proceed downward and are attached to the ends of a transverse rod, f, whichhas'connected to it a treadle, E.' This treadle 1s used for depressin g jthe rollers d d d, and the springs c'c are used for 'elevating the .rubbing-rollers d d d.. The lrollers d have their'end'bearings in the segmental. side pieces, g g, which are ,connected together by transverse bars g"g, l and the 'whole are connected to parallel `arms h h,`which are 'suspended from the rock-shaft D. In one end of the box Athe"cncave or wash-board is arranged, the surface ot'which is concentric with the center of vibration of of the rubbing-.rollers when these rubbers are at their highest point.- (Shown in-Fig. l.) This wash-board .is made up of a number of slats which have spirally-ribbed surfaces, the ribs of which run in opposite directions on each alternate slat, so that a number ot' such slats, t' i, arranged side by side, present the appearance of zigzag-ribs running-from one side'of the box to the other, as shown inv Figs. 2 and' 4. These spirally-ribbed slats t' incline downward from the upper toward the lower end of the inclined'end of box A, and they are nailed to transverse ledges lc 7c 7c. (Shown in Fig. l.) These rubbing surfaces or slats are furnished with a bottom board, G, which forms aspace, m, beneath them for containing strong soapsuds, vand the ledges k 7c keep a sufficient quan'- tity of soapsuds under the slats for all practical purposes. The serrated or scalloped edges of the slats t' i do not :tit so closely together as to prevent the soapsuds beneath them from mixing with the water which is drawn up from the main body-of the'tub A with the clothes as they are brought 'over these slats to be rubbed; but should' these spaces not be found sufficient, the slats themselves may be perforated, the perforations be-r ing made between the ribs, -as shown in the drawings, Figs. 2 and 4.' The rubber is composed of a number of rollers, d d, arranged in a curve 'concentric withl the axis ot' the rockshaft Dl (Shown in Fig. l.) These rollers are spirally grooved, the grooves running 'from oneendof one roller to about two-thirds the length of this roller'in'one direction,'and for the other third in the opposite direction', Thus, at the ends of these" rollers the groove'srun in opposite directions, the object ot' which is to cause the rollers to move the clothes, which are subjected to their rubbing action, toward having a right and left spiral groove formed.

in its surface, the tendency is to move the clothes back and iorth laterally on the Wash- 'board7 and thus to subject every portion thereof to the rubbing and squeezingaction of the two spirally-grooved surfaces of the rubber and wash-board.

In using the machinewater is put into the main body of the tub, and strong soap and water, soft soap, 'or washing co1npound7of any description, and the clothes are drawn from the rinsing Water in the tub over the concave wash-board where the soapsuds. contained in the space on will mix with the water in the clothes as they are rubbed and squeezed by the rubbing-*rollers d d d, the'pressure of these rollers being increased or diminished on the clothes by pressing with greater or less force upon the treadle E. The strong soapsuds can in this way be brought to actdirectly up-4 on the clothes in only such quantities as may be required, and being kept in a sepaiate receptacle there will be a great deal of soap saved which would otherwise be mixed With the body of Water in the tub A.

What I claim as'my invention is 1. The wash board lcomposed of alternately rightand left or zigzag open surfaces, substantially as described.

2. A wash-board constructed with a soapf suds receptacle, m, arranged beneath the openslatted surface i i, substantially as and for the purposes described. l

3. Combining with the zigzag-ribbed and waved Wash-board the spirally-ribbed rollers7 the ribs of Whichrun in opposite directions on each roller, substantially as and for the purposes herein described.

Witness myhand in the matter of my application for a patent for an improved Washing-machine this 11th day of June, A.D. 1863'.
