WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 304,554, dated September 2, 1884.

l Application filed August 16, 1883. (No model.)

.To all whom, t may concern:

Be it known that I, Cimnnns PELMULDER, a citizen of the United States, residing at Rockwell City, in the county of Calhoun and State of Iowa, have invented certain new and useful Improvements in \Vashing-l\Iachines, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the Same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in roller and bed washing-machines; and it consists in the construction, combination, and arrangement hereinafter described and claimed.

In the drawings, Figure l is a side view of my machine in position in a suds-box, the latter being broken away to better show the machine. Fig. 2 is a front View; Fig. 3, a rear View, and Fig. 4 is a vertical section, of my machine on line x x, Fig. 3, and Fig. 5 reprein detail, and Fig. 6 is a detached vertical section showing the motion of the supplemental frame and the back board.

The main frame of my maehineis composed of the two side boards, A A, the upper and lower rear cross-bars, A A2, and the two side cleats or plates, A3, and the brace-board A4, all arranged as clearly shown. The side boards, A A, are constructed with the opening a, in which the supplemental frame, hereinafter described, is placed and operates. r

The rollers B B are journaled in the side boards, A A, in front of the opening a, and respectively near the upper and lower ends of the main frame. In practice I preferto journal the upper roller, B, in bearings b, which are movable up and down in the slots or mortisesb, in which they are placed, and to adjust these bearings by set-screws b2, having thumb heads b3. These screws are passed through threaded bearings b4 and swiveled at their lower ends to the bearings b, so that as the said screws are turned the bearings b and the roller B will be adjusted up or down, so as to vary the tension of the endless rubber, hereinafter described. This endless rubber C is composed of corrugated slats c, mounted on the iiexible belts c', and it is placed around the rollers B B', as most clearly shown in Fig. 4. This endless belt is given motion by the revolution or" the roller B, which is provided with the operating-crank B2.

In operation the direction of motion is that indicated by the arrows, and the face of the slats c in their upward passage from roller B to roller B move about in line with the forward wall, a', of the opening a. On the slats c, I secure loops clz c3, by means of which the clothing to be washed is held to the endless rubber.

The supplemental frame is composed of the side bars, D D, and the bar D', fastened at its opposite ends to the bars D, on the rear edge oi' and near their lower ends. This frame is made of a width equal that of the main frame, and it is placed in the opening a of the side boards, A, and its side bars, D, are movable to and from the wallet oi the said opening a.l The supplemental frame is pivoted at its upper end to the main frame, preferably by means of the pins d, passed from its side bars, D, into the cleats A3 of the said main frame, and its lower end is connected with the said main frame by coil-spring D2, secured at one end to the supplemental frame, and extended to and secured to the main frame at a point in front of the opening a. I prefer to form this latter connection by forming hooks d on the forward end of springs D, and arranging a series of eyes, d, on the boards A, so that the hook d can engage any one of said eyes desired for the purpose ofY increasing or'din1inishing the tension of the spring D2 on the lower .end of the supplemental frame, according to the character ofthe articles being washed. The wash-board E is pivoted between the bars D of the supplemental frame. Its lower end butts against the bar D of said frame, and its upper end is supported, with a capacity to yield backward, bythe spring E', mounted on cross-bar A of the main frame, and bearing` between the same and the rear ot the board F at or near the upper end of the latter. By this construction it will be seen that the back board at its lower end partakes of the yielding motion of the lower end of the supplemental frame, and at its upper end has an independent yielding support, as shown. This back board is provided on its face or side next the ICO rubber C with the corrugated facing El, and washed during the whole of their passage bcits lower edge next the rubber C is rounded, as shown in Fig. 4,to permit the clothing t'o be readily drawn up between the back board and the rubber in the operation of Washing. Normally/,the springs D2 hold the supplemental frame close against the walls a of opening a, and the back board, E, flush against the endless rubber, as indicated in dotted lines, Fig. 1 but as heavy clothing vor other articles are drawn. between the rubber and back board .l or bed, the said frame is forced out to about its position shown in the said figure and Fig. 4.

ln practice su'licient water is placed in the suds-box F and the machine is placed down therein. The articles to be washed are then secured to the rubber C by loops 02 or c, and motion being given the said rubber, as described, the articles are drawn rapidly through the water, thence up between the rubber and tween the rubber and the bed or back board, and the operation of the machine is rendered even and the dirt is rubbed and pressed out of the articles.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

that supported by the bar D, all substantially as described and shown, and for the purposes specified.

In testimony whereof I affix my signature in the presence of two witnesses.
