JOEL WISNER, 0F AURORA, NEW YORK.

WASHING-MACHINE.

Speceaton of Letters Patent No. 10,219, dated November 8, 1853.

To all whom t may concern Be it known that I, JOEL VISNER, of Aurora, in the county of Erie and State of New York, have invented a new and useful Improvement in lVashing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and oper-ation of the same, reference being had to the annexed drawings, forming part of this specification, in which- Figure l is a top view of the machine with rubber removed. Fig. 2 is a vertical section of complete machine, on line a2-w of Fig. l. Fig. 3 shows a cross section of radial ribs f and m taken on line g/-g/ Fig. 2.

Similar letters indicate like parts of the machine.

The nature of my invention consists in 'constructing the interior surface of the bot tom of the tub, and underside of the rubber, with radial ribs in the form of semi-frusw tums of cones, with their larger bases toward the exterior' of the tub and perimeter of the rubber; the under surface of the rubber being beveled outward and upward, so that the elements of the ribs on both rubber Vand bottom, which are farthest from said surfaces, will be parallel when the ribs have the position shown in Fig. 3, forming elements of concentric conical surfaces respectively parallel to each other: the effect being to furnish space for the clothes between the ribs, and to prevent their drawing toward the center of the machine, and otherwise to facilitate the cleansing process, by causing the clothes to move toward the perimeter of the tub and at the same time turn them over in the spaces between the ribs, as the rubber is rotated, which effect diifers from that produced in other circular wash tubs having rotating rubbers, as I have found by long experience in the use ofwashtubs of this character and which renders this machine superior to others in use.

In the drawing B is the tub and C the. rubber, the bottom a of the former and under surface of the latter having the radial ribs f and m, consisting of semi-frustums of cones with their larger bases toward the sides of the tub; the under surface of the rubber being so beveled as to bring the outer element of the rib fm, parallel to the corresponding element of any rib f directly beneath it; or, to make the surfaces generated by the revolution of said elements about the axis of the rubber and tub parallel to each other. Through the middle of the tub passes the spindle F, having on it the seat G, which limits the descent of the rubber. From the top of the rubber arise the standards It, across which is the beam I-I, perforated in its center to receive the spindle F.

The operation of my machine is as fol lows: The clothes to be washed together with the requisite quantity of water and soap, are deposited in the tub and the rubber pla-ced upon them, by passing the opening in its center, and the perforation in the beam H over the spindle F. The operator then grasps the handles T of the beam H, and causes the rubber to perform alternate semirevolutions about the spindle F, the weight of the rubber and the motion given to it causing the ribs upon the rubber and bottom, to press, rub, and agitate the clothes suiiicient to remove their impurities without injury to their texture.-

This construction of ribs and rubber differs from t-he iiuted rubbers and bottoms in ordinary use, inasmuch as the space between the rubber and bottom of the tub, is greatest at the periphery of the rubber, giving the clothes a tendency to the sides of the tub, instead of drawing them to the spindle, where they will receive but little agitation and are liable to be Cut. This machine for simplicity of construction and facility of operation is superior to most washing machines in use, and only requires a test to render its merits apparent- I do not claim in general the use of a horizontal circular rotary washboard in the bottom of a wash tub when they are used with the ordinary radial iiuting, as such has been long known, but what I do claim is the following, viz:

Making the said wash board of a conical form having its surface higher above the bottom of the tub at the circumference than at the center, and attaching to it and to the bottom of the tub radial ribs of the form of a half cone, when these ribs are formed of such depth, and with spaces so wide between them, as to receive the clothes in those spaces in such manner as to turn or roll them over as the board is rotatedv back and forth, as above described.

In testimony whereof, I have hereunto signed my name before two subscribing witnesses.

JOEL VVISNER. Witnesses:
