WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No, 351,289, dated October 19, 1886.

Application tiled March 29, ISSG. Serial No. 196,996. (No model.)

To @ZZ whom it may concern:

Beit known that l, MAX F. E. S'rAD'riiiUnL- LER, a. citizen of the United States, and a resident of Castle Grove, in the county of J ones and State of Iowa, have invented certain new and useful Improvements in Vashing Machines; and l do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appert-ains to make and use the saine, reference being had to the aecompanying drawings, which form a part of this specification, and in which-d Figurc l is a longitudinal vertical sectional view of my improved washingmachine, showing it in condition for operation. Fig. 2 is a similar view of the machine, showing the lid raised and the revolving rubber raised and supported above the rocking bottom. Fig. 3 is a perspective view of the rocking bottom, showing portions broken away. Fig. fl isa similar view of the rubber and ils frame, showing portions broken away. Fig. 5 is a top view of said machine.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of washing-machines in which a corrugated roller is j onrnaled between the ends of arms and reciprocated over a corrugated bottoni, and it consists in the improved construction and coinbination of parts of such a machine, having a roller provided with a number of cross-slats secured in the edges of two heads and rolled over a bottom composed of similar slats secured to two side pieces having a bulged central portion, causing the said bottom to rock, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the suds-boX, which is suitably mounted upon legs B, and which is provided with metallic strips C G, secured upon the inner sides of the side pieces near the upper edges, and parallel with the same. The Slat bottom is composed of two side pieces, D D, having their lower edges bulged at their centers, and square slatsE are secured with their ends in perforations F in the side pieces parallel with the lower edges of the same, and have their edges projecting upward, and

spaces between them. The side pieces of the rocking bottom are provided with laterallyprojectingbolts G G at their middles, and these bolts lit into perforations Hin the lower ends of metallic strips l, secured upon the inner sides of the side pieces of the suds-loox, near the lower edges and at the middles ofthe same, allowing the bottom tvo-rock upon these bolts as well as with the hul'ged side pieces upon the bottom of the suds-box.

A roller is composed of two circular heads` J J, having their centers countersunk from the outer faces, and connected at their centers by means of a shaft, K, inserted through the centers of the heads, and secured by means of nuts M upon the ends ofthe rod or shaft ltting in the countersinks N ofthe heads. The inner faces .of the heads are formed with triangular shoulders O, and the ends of square strips P fit into these shoulders, the ends being cut away at the portions which tit into the shoulders, forming shoulders Q, resting upon the edges ol" the heads, and the strips are secured to the heads by means of nails or screws R, inserted through the heads into the cutaway portions of the strips.

The ends of the shaft are smooth and project beyond the screw-threaded portions which have the nuts, and these smooth ends are journaled in the lower ends of arms S S, the upper ends of which are bifurcatedand connected by means of cross-pieces T T, secured to the upper bifurcated ends of the arms. A bar, U, is secured at` its inner end to the crossbars, and has its outer end pivoted to a lever, V, near the upper end of the same, the lower end ofthe lever being pivoted in the end of a slid ing bar, NV. This bar slides under the bottom of the suds-box in a notch, X, in the crosspiece at that end of the bottom and in a bulge made in a metallic strip, Y, secured to the under side of the cross-piece, and the sliding bar is provided at its inner end with a downwardly-projecting pin, Z, which stops the bar from sliding out too far, and at its middle the sliding bar has a perforation, A, which may register with a perforation, B, in the notch of the cross-bar, through which perforations a bolt, C', or pin may be inserted, holding the sliding bar at its desired distance out.

The cover D of the suds-box consists of two IOO longitudinal bars, Ef, the ends of which rest in notches F in the ends of the suds-box, and the end of the cover nearest to the operating-lever is provided with a wide board, G, to which a 5 bolt, H, is pivoted by means of a staple, Il', which bolt may support the outer cross-piece of the rubber,which cross-piece is formed with with a recess, J', in its under side, into which the end of the bolt may t, lifting the rubber 1o up from the rocking bottom, and keeping it at that end of the suds-box, as shown in Fig.

2. A lid, K', is pivoted at its end at theinner edge of the wide board tothe side piece, E', and at the free end of the said cover is a narrow board, L', and a downwardly and outwardly inclined board, M', which leaves space upon the upper edge of that end piece of the suds-boxl to secure a clothes-wringer upon it. The longitudinal bars of the cover are secured 2o in their notches at a sufficient distance from the side pieces of the suds-box to allow the bifurcated arms of the rubber to slide between the longitudinal metallic strips upon the side pieces and the longitudinal bars of the lid. It will be seen that as the rubber is reciprocated or rolled over the rocking bottom the bottom will be depressed at the end at which the roller is, and in this manner theroller will depress the bottom and the clothes upon the same into the water, while the otherend of the bottom will be above water, causing the water to rush through the clothes, and thus cleanse them, and at the same time throwing the clothes upon the bottom with sufiicient force upward from the bottom, in its upward motion, that other surfaces'will be exposed.

When the machine is not used, the sliding bar having the lever pivoted to its outer end is slid in under the machine, so as to be outof the lo way, and when it is to be used the bar is drawn out until the perforations in the bar andin the notch of the cross-piece correspond, when the pin or bolt is inserted, holding the bar rigid.

Having thus described my invention, I claim and desire to secure by Letters'Patent of the United Statesl. In a washingmachine, the combination of two rubber-heads having countersunk centers, and having triangular shoulders upon their inner sides, square strips having their 5o shown and set forth.

2. In a washing-machine, the combination 6o of a suds-box having a cross-piece at one end of its bottom provided with a notch in its upper edge having a perforation in the notch, a bulged strip of metal secured to the under side of the bottom of the suds-box, a rubber having an outwardly-proj ectingbar, abar sliding in the bulged strip and in the notch,l and having a perforation registering with the perforation in the notch, a pin for the perforations, and an operating-lever pivoted in the outer 7o end of the sliding bar, and having the outer end of the bar of the rubber pivoted near itsv upper end, as and for the purpose shown and set forth.

3. In a washing-machine, the combination of a sudsbox having two metallic strips secured to the inner sides of the side pieces near the upper edges and having a rocking slat bottom, a lid having two longitudinal bars resting with its ends in notches in the end pieces ofthe suds-box and havinga pivoted cover,and a rubber having a Slat-roller journaled in the ends of arms sliding between the longitudinal bars of the lid and the strips of the side pieces of the suds-boX, and connected by cross-pieces 8 5 having means for reciprocating it, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto aixed my signature in presence of two witnesses.

MAX F. E. STADTMUELLER.
