EDIVARD G. ELLIS, OF POMONA, ILLINOIS ASSIGNOR OF ONE-THIRD TO JESSE T. MCKINNEY, OF POMONA, ILLINOIS.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 765,918, dated July 26, 1904.

Application filed March 30, 1904.

To rtZZ whom, it may concern.-

Be it known that I, EDWARD Gr. ELLIS, a citizen of the United States, residing at Pomona, in the county of Jackson, State of Illinois, have invented certain new and useful Improvements in \Vashing-Wlachines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a washing-machine, and particularly to a structure embodying concentrically-disposed oscillating rubbers.

The invention has for an object to provide a construction wherein the rollers forming the rubbing-surface of the oscillating rubbers are adapted to be positively rotated in the movement of the rubber, so as to provide the proper frictional contact with the clothing washed without danger of tearing the same or removing the buttons therefrom.

A further object of the invention is to provide means for oscillating the rubbing-segments simultaneously in opposite directions and rotating the rollers of the lower segment during such movement.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is a perspective of the invention; Fig. 2, a vertical longitudinal section; Fig. 3, a vertical cross-section thereof, and Fig. 4 a detail perspective of one of the rollers.

Like letters of reference refer to like parts in the several figures of the drawings.

The letter A designates the tank or receptacle adapted to contain the parts of the washing-machine, which may be of any desired configuration, preferably segmental in form, and supported in any preferred manner-for instance, by means of legs A at the opposite sides and ends thereof. This tank is provided upon the upper edge of the side walls thereof at substantially its mid-length with a bearing A adapted to receive the pintles B of the lower rubber B, which is of segmental form and composed of opposite side walls B secured together in any desired mannerfor Serial No. 200,796. (No model.)

instance, by means of a cross-bar B Journaled in the walls B at their opposite ends 5 O are a series of rollers B, each of which carries at one end a pinion or gear wheel B for the purpose of positively rotating the roller. These rollers, if desired, may be provided with spirally-disposed grooves 13, extending longitudinally thereof, which materially assist in the washing action of the roller in its contact with the clothes within the machine. These rollers may be positively rotated during the oscillation of the lower rubber by any desired means; but as showing one convenient form thereof a segmental rack -bar A has been disposed within the tank A and in position to engage the teeth of the pinions B carried by the rollers B so as to positively 5 rotate the latter in the oscillation of the rubber.

The upper rubber C is pivotally mounted by means of a pivot C, disposed above and in alinement with the pivot B, while the rubber is composed of opposite side walls O seg- 7 mental in shape, which provide bearings for the rubbing-rollers 0 said rollers being provided at opposite ends with pintles O, journaled in said side walls. These rollers are provided with longitudinally-extending spiral 7 5 grooves O similar to those in the rollers 13*. The pivots C of the upper rubber are herein shown as mounted in standards A*, having an open-ended bearing slot A therein. The rubbers are thus disposed with their curved 30 faces concentric to each other and in the washing operation are oscillated in opposite directions.

For the purpose of securing the oscillation an operating-handle D is secured to the cross- 3 5 bar D, which is pivotally mounted at its opposite ends in standards D carried by the tank of the machine. At the inner end of this handle depending links D are provided, which are pivotally connected at their lower ends to 9 the upper rubber and at their upper ends to the handle D. Upon the opposite side of the pivoting-bar D links D extend downward and are pivotally connected to the handle D and to the end of the lower rubber B.

By reference to Fig. 2 it will be seen that an operation of the handle I) oscillates the rubbers in opposite directions from the fullline position there shown to the dotted-line position, thus securing the desired rubbing action between the two rubbers, and during this movement the rollers in the lower rubber are positively rotated by the rack and pinion, so as to prevent the tearing of buttons from the clothes and also any possibility of tearing the clothes in the relative movement of the rubbers. This positive rotation also produces a rubbing action through the medium of the grooves upon the surface of the rubbers upon the clothes resting thereon. The operatinglovers are so disposed as to produce an equalization of power required for the oscillation of the rubbers through a simple movement of the handle.

' It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is

1. In a washing-machine, the combination with a tank, of an oscillating rubber mounted therein, rollers pivotally mounted in the periphery of said rubber, and means carried by the tank for positively operating said rollers.

2. In a washing-machine, the combination with a tank, of an oscillating rubber mounted therein, rollers pivotally mounted in the periphery of said rubber, means carried by the tank for positively operating said rollers, an upper rubber provided with rotatable rollers and mounted within the first-mentioned rubber, and means for simultaneously oscillating said rubbers in opposite directions.

3. In a washing-machine, a tank provided with a rack-bar therein, an oscillating rubber pivotally mounted within said tank, a series of rollers pivotally mounted in the walls of said rubber, each of said rollers being provided with a pinion engaging said rack, and means for oscillating said rubber.

4C. In a washing-machine, a tank provided with a rack-bar therein, an oscillating rubber pivotally mounted within said. tank, a series of rollers pivotally mounted in the walls of said rubber, each of said rollers being provided with a pinion engaging said rack, means for oscillating said rubber, an upper rubber pivotally mounted above the pivot of the firstmentioned rubber, rotatable rollers mounted in the curved faces of said upper rubber, a pivotally-mounted handle, and links at the opposite side of the pivot of said handle and each connected to one of the rubbers.

5. In a washing-machine, a tank provided with a segmental rack-bar in its lower portion, a segmental rubber disposed within said tank, longitudinally-grooved rollers pivotally mounted in the opposite walls of said rubber, and pinions carried by said rollers to engage said rack-bar.

6. In a washing-machine, a tank provided with a segmental rack-bar in its lower portion, a segmental rubber disposed within said tank, longitudinally-grooved rollers pivotally mounted. in the opposite walls of said rubber, pinions carried by said rollers to engage said rack-bar, an upper rubber pivotally mounted in alinement with the pivot of the lower rubber, rotatable rollers mounted in the side walls of said upper rubber, standards at the opposite sides of said tank, a bar pivoted in said standards, a handle connected to said bar and extending laterally therefrom, and links pivotally connected to said handle at opposite sides of said bar and at their lower ends each pivotally connected to one of the levers.

In testimony whereof I affix mysignature in presence of two witnesses.
