To ttZZ whom it may con/cern.:`

Be it known that I, JOHN L. OONNER, a citizen of the United States, residing at Washington, in the District ot' Columbia, have invented new and vuseful Improvements in Washboards, of which the following is a speci'-A cation. Y A

This invention relates to certain new and useful improvements in washboards; and a particular object' of the invention is to provide the board with an improved means whereby particles of soap are automatically fed to the clothes during the rubbing operation.

The invention consists of the parts and the construction and combination ot' parts which:

I will hereinafter describe and claim.

In the accompanying drawings, forming part of the specification, and in which similar letters of reference indicate corresponding or piece of soap used in-washing is usuallyA placed.

The washboard herein shown for purposes of illustration consists of the frame composed of side members a., top and bottom cross-bars b, a rubbing-surface c, and a back attachment or board d, connected to the outer surfaces of the sides ct by pivoted links c, said board d having ratchet-shaped bars f to engage the top of the tub and said links allowing the back attachment to adjust the board in the manner common to this class of devices. The board thus shown and described being old and well-known prior to my inven.- tion, I do not claim the same independent of the attachment and means I will hereinafter describe. Neither do I limit my real invention to this board or to any particular frame of board or rubbing-surface.

The improvement I have made-to the washboard includes a plurality of rollers A A' A2, extending, preferably, full across the space above the rubbing surface c between the sides a and having their ends suitably journaled. Where the device is to be used as an attachment for the boards now in use, I will employ as a part of said attachment the side plates B, having elongated slots B, in which the vends of the rolle'rpintles are loosely mounted, said plates B being screwed or otherwise fastened to the inner surfaces of the sides a of the washboard.

The rollers have such diameter relative to the width of the side bars a vthat the circumference of the rollers is substantially in the plane of the rubbing-surface of the board, said rollers forming substantially a continuation of the upper end of said rubbing-surface, the clothes being` alternately dragged and pushed over the rollers to cause rotation of the latter as the rubbing process is proceeded with. The rollers are also longitudinally grooved, as at D, and a preferred though not essential formof the groove is ratchet-shaped to provide a cutting edge which sweeps past the bar or cake of soap and by a cutting action removes a shaving or film of soap fromV the action of drawing or pushing the clothes over them the walls of the grooves of the rollers cut into the surface of the cake or bar and shave o small but sufficient amounts of soap to insure the proper amount of soapy water or suds for the cleansing of the clothes. As the surface of the soap bar or cake is removed and the thickness of the bar or cake reduced the rubbing pressure causes the front and back portions of the board to come closer together, swingiuguupon the links e, thus insuring the clamping of the cake or bar under all conditions and until it is actually ICO cut through by the rollers. In other Words, the swinging back member continually feeds the soap bar or cake to the rollers and the latter remove and feed the portions of soap to the clothes. In addition to being longitudinally grooved the peripheries of the rollers may be roughed by oblique or other grooves g interspersed between the lines of longitudinal grooving.

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

In a washboard, the combination of side bars, a rubbing-surface, and a swinging back,
