WASHlNG-MACHlNE.

SPECIFICATION forming part of Letters Patent No. 426,367, dated April 22, 1890.

Application filed February 21, 1890. Serial No. 341,302. (No model.)

To all whom it may concern.-

Be it known that I, NICHOLAS DENNY, a citizen of the United States of America, residing at Saranac, in the county of Ionia and State of Michigan, have invented certain new and useful Improvements in \Vashing-Machines; and I do hereby 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 letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in washing machines; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth and particularly claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view of a washing-machine Fig. 2 is an end view, partly in section. Fig. 3 is a detail view.

A refers to thetub orboX, which is provided with a metallic bot-tom and supporting-legs. Centrally on each of the side pieces which form the tub, and near the lower edge thereof, are rigidly secured spring-bars .B, the upper ends of Which are enlarged and provided with perforations Z). From one of the edges of these spring-bars opposite the perforations are recesses having inclined or beveled faces I), and the upper and lower edges of these recesses are also inclined to provide a wide mouth and small throat, so that the pins on the cross -bar can be easily guided into the perforations. Above the perforations these bars B are provided with handles, so that they can be drawn or pushed outwardly for releasing the bar 0, and excessive outward movement of the upper ends of the springbars B is prevented by loops d. The upper edges of the side pieces of the tub are cut away or rounded beneath the perforations Z). The side pieces of the tub on their inner faces have a curved or segmental strip attached thereto immediately above the bottom, the upper ends of which project to form notches, and upon these strips and notches the corrugated bottom boards E rest.

These bottom boards are made up of three or more sections, and where the sections meet each other offsets are formed, so as to provide openings through which the dirt from the clothes can pass to the bottom of the tub. These curved bottom sections E are each provided with a central smooth portion, adjacent to which are formed ribs or corrugations, and when the full number of sections are in place they will be held against movement by the projections which overlap the ends of the two upper sectlons.

To one end of the tub is secured a bifurcated block F, between which'is pivoted one end of a bar G, the opposite end thereof being pivotally secured in a slot in a bar H, which is provided at one end with a cross-bar or operating-handle, while near the other end it has a slot in which is pivotally secured the bar I, which carries arubber of ordinary construction and has a corrugated rubbing-face. The bar I passes through the rock-shaft O, the central portion thereof being enlarged for this purpose, and this shaft I has a pin which limits the downward movement of the same, as shown at 'i, as well as a projecting pin i, with which one end of a spiral springl engages, the body portion of said spring encircling the bar I, while its lower end is rigidly secured to the rock-bar. By this means the rubber will have a constant downward pressure upon the clothes. The rubber may be raised by bearing upon the handle-bar so as to raise the rubber to its full extent when it is desired to place the clothes beneath the same. By simply moving the handle -bar backward and forward the rubber is oscillated over the clothes. The rubber can be removed from the tub when it is desired by simply spreading the upper ends of the spring-bars apart, and then. the rubber can be supported. above the box or tub.

I am aware that prior to my invention washing-machines have been provided with oscillating rubbers and a spring for holding said rubber in contact with the clothes, and I do not therefore claim such construction, broadly; but
