WASHING-MACHINE.

' SPECIFICATION forming part of Letters Patent No. 514,703, dated February 13, 1894.

Application led November 29, 1893. Serial No. 492,327. (No model.)

To all whom t may concern.-

Be it known that I, TYRANNUs P. BUTTER- FIELD, a citizen of theUnited States, residing at North Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Washingl Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, su ch as will enable others skilled tween the entire rubbing face of the rubber and the clothes in order to expedite the washing and also to avoid over-rubbing of the clothes in parts.

I accomplish the objects of this invention by the mechanism illustrated in the accompanying drawings in which- .Figure 1 is a view in perspective of my complete machine. Fig. 2 is a view in side elevation showing the near side partially broken away to show the construction and arrangement of the rubber, the gure shows the rocking rubber in dotted lines as it appears when thrown back to allow the operator to turn the clothes or to remove them or renew the supply. Fig. 3 is a detail in partial transverse section of the suds box showing the rocking rubber as constructed in three sections independently movable, and shows portions of two of the sections broken awayy to better illustrate the construction. Fig. 4t

. is a detail in side elevation and sectioned, of

one of the pieces of the rocking rubber. Fig.`

5 is a detail showingV the construction of the rub-bars on the bottom of the suds box, and Fig. 6 is a detail showing the construction of the cap for closing the water outlet to the suds box.

Similar letters refer to like parts throughoutV the several views of the drawings.

A is the suds box and is shown in the drawings as having wooden sides and sheet metal' bottom, the metal being used on account of the facility with whichit can be bent to conform to the curved shape desired. One end of the machine will be provided with the board A which will present a considerable surface upon which the hand wash board A2 will be located, the said board extending only a por- 6o tion of the wayacross the width of the machine so as to leave a space between the wash board and the side of the machine to be used as a soap receptacle. The cross strip a, will form a stop to keep the barof soap from sliding into the suds box and will have a cut under portion to allow the water to drain into the box. The suds box will be supported on the .legs A2 iu the usual manner.

B are the rub-bars to be located on the bot- 7o tom of the suds box and are corrugated strips of wood arranged transversely across the machine. These strips are separated by the blocks b, and the blocks and strips will be held together by being strung upon the Wires 7 5 B', which wires pass through suitable holes in the ends of the strips and through the blocks as shown, thereby enabling the bottom rubbars all to bek taken out together, and to be handled as one piece when it is desired to re- 8o move them in cleaning the machine.

C is a convex corrugated rubber pivotally secured to the sides of the suds box so as to have a swinging movement by means of which 'the clothes which are placed between the up- 85 perA rubber C and the lower rubber B are cleansed. The peculiar construction of this upper rubber C by which it may adjust itself to the varying thickness of the clothes in the Y machine constitutes the principal feature of 9o my invention and will 110W bev particularly described: The rubbers proper are suspended from a frame consisting of the side pieces C which are joined together at the top by the cross bar c, which cross bar also serves as a handle by which the operator grasps the frame to s'wingthe rubbers. The lower ends of the side pieces are held together by the cross bar c2 which also serves an additional purpose, as will be described farther on, and c is the axle roo or pivot upon which the frame swings and consists of a hollow tube, preferably a piece of gas pipe, which is projected through both sides of the frame and projects a suitable distance on each side of the frame, or side pieces, to engage the sides of the suds box. A notch will be cut in each side of the suds box into which the ends of the tube will be dropped so as to hold the frame at a certain position in the box. The upper rubbers will be secured to the two bars c and c2 and the rubbers themselves will be made in independently movable sections, three being shown in the drawings although any other number may be adopted if so desired. As shown in the drawings these sections will be constructed of the side pieces D', curved on their bottom sides to conform to the curvature of the bottom of the suds box, and will have a series of corrugated strips D2 secured to the bottoms of the side pieces as shown. Each of the sections of the rubber will be provided with the radial slot D3 and will be attached to the pivoted frame, previously described, by passing the two lower cross bars c and c2 through the slot in the sections as shown in Figs. 3 and 4. rlhe cross pin D7 above the bar c2 will keep the sections from dropping off of the bars and the dept-h of the slot will regulate the height of the adjustment of the sections on the frame. The sections will be weighted sufficiently heavy to give the desired rubbing pressure on the clothes and will cause the rubbers to drop down sufficiently to always be in contact with the clothes, but on the other hand will be free to move up again when the thickness of the goods underneath the rubbers may require it, thus preventingr the machine from rubbing to excess on the highest place as would be the case if the top rubber were a continuous and rigid surface as heretofore used.

In practice the several sections of the rubber will preferably be made, either wholly or in part, of metal in order to give the needed weight and pressure and also to prevent the undue swelling of the several sections, which, when made of wood swell up by the action of the steam and water to such an extent as to interfere wit-h the freedom of movement of the sections.

Passing through the tubular pivot C is an iron rod R, the ends of which are bent back at right angles and extended to a point about midway between the pivotal point of the :frame and the end of the machine next the operator, where the extreme ends are then again turned in at right angles and are dropped into the slots a3 in the sides of the machine thus forming a double hinged connection of the frame with the suds box and thereby enabling the rubbers to be thrown back and raised out of the way for convenience in reaching the clothes in the suds box. The position is shown in the dotted lines in Fig. 2.

M is the outlet through which the suds is withdrawn in changing the water in the machine and will preferably be closed by the pivoted cap N which is secured to the machine by the screw n, so it can be thrown around to expose the opening. A rubber or leather packing secured to the inside of thev cap will make the closure water tight.

I claiml. In a washing machine a suds box having concave stationary rub-bars on its bottom in combination with a rocking rubber pivotally secured to the sides of the machine and having handle bars by which the rubber may be vbrated, said rocking rubber beingr made in separately movable sections that will rise and fall automatically as the bulk of clothes beneath such section is increased or diminished substantially as described and lfor the purposes specified.

2. In a washing machine having a concave rubber on the bottom of the suds box, the combination therewith of a rocking rubber pivotally secured to the sides of the machine and constructed of the following parts: the side pieces C', top cross piece c, tubular cross bar c' having projecting ends to form pivots by which the rubber will be suspended, and the cross bar c2, a rubber proper constructed of several sections each of which sections are provided with a radial slot to receive the cross bars c and c2 to control the movement of the sections, and cross pins D7 all for the purposes substantially as described and speci fied.

3. In a washing machine having a rocking rubber, the tubular pivot extending from one side of the rubber to the other and forming a tie rod to connect the side pieces of the handle bar frameand projecting at either end to form the pivots for the rubber and a rod projected through the tubular pivot and bent at right angles to form an arm, the extreme ends of which will be removably pivoted to the frame of the machine for the purposes specitied.

Intestimony whereof I ailix my signature in presence of two witnesses.
