`UNITED STATES JOHN IVELDING, 0F CINCINNATI, OHIO.

IMPROVED WASHING-MACHINE.

Specification forming part of Letters Patent No. 50,973, dated November 14, 1865.

.'b all whom it may concern:

Be itknown that I, JOHN WELDING, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Washing-Machine and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing7 making part of this specification. Y

My invention relates to that class of washing-machines having a swinging tub, between the bottom of which and a stationary rubber the clothes are operated upon and it consists in providing the bottom of the swinging tub with a series of rubbing-rollers, the line described by the faces of the rollers collectively being eccentric to that described by the station-ary rubber when the machineis in motion, the said tub being closed by suitable covers when the machine is in operation.

Theaccompanying drawing is a cross-sec tion of a washing-n1achine embodying my improvement.

The swinging tub A is journaled at a to the vertical posts B ot' the stationaryrubber C, the whole being connected, as shown, to the frame D. The bottoni of the tub is semi-cylindrical, and is provided with a series of rubbing-rollers, E. The point a, at which the tub is jonrnnled, is below the center of the circular arc described by the faces of the rollers collectively, so that the distance between the rubber C and the face ot' the rollers increases .as the tub is oscillated in either direction. This eccentric arrangement of the parts enables the clothes to be collected easily between the stationary rubber C and the rollers E at the points ot' the widest opening, to be, in turn, submitted to severe pressure when the rubber is nearest to the rollers. The edges ofthe tub at b b are cut away to form handles for the operator.

F F are covers resting in suitable slots on the sides ofthe tub and kept in place by the projections ofthe handles atff.

I claim herein as new and of my invention- The swinging` semi-cylindrical tub A, hung eccentrically at a, and havingjournaled slightly within and concentric with its concavity a series ot' rollers, E, the same being combined with the stationary pendent rubber C, covers F F,and projectionsff, substantially as set forth.

In testimony of which invention I hereunto set my hand.

JOHN WELDING.
