UNITED STATES PATENT OFFICE.

S. E. LAUPHEA'R AND O. D. BARRETT, OF CLEVELAND, OHIO.

WASHING-MACHINE.

Specification of Letters Patent No. 25,838, dated October 18, 1859.

To all whom it may concern:

Be it known that we, STEPHEN E. LAU- ri-IEAR and OLIVER D. BARRETT, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in I/Vashing-Machines; and we do hereby declare that the following is a full and eXact description thereof, reference being had to the accompanying drawings, making a part of this specification.

In the drawings like letters represent the same part.

Figure 1 is a perspective View and Fig. 2 a vertical section of the said improvement.

A represents the tub.

B represents permanent standards.

C represents sleeve.

D and E represent disks.

F represents lever.

G represents standard. H, H, connecting rods; I, joint; J, operating lever; K, hinge; L, bottom board; M, M, springs.

The nature of our invention consists in `attaching to the center of the tub A, Fig. 2, the permanent standard B, on which is placed the sleeve C, having its upper end solid and square, and having on its lower end a iange for the fastening to it of the disk D. This sleeve and disk revolve upon the point of the permanent standard B. Around the sleeve C, Fig. 2, revolves the disk E. The two disks D and E have their adjacent sides ribbed or grooved but we do not confine ourselves to any particular form of ribs or grooves. In the disk E, Fig. 1, is placed the standard G. To this standard is attached a connecting rod H, connecting the disk E to the operating lever J. On the sleeve C, Fig. 1, is placed the lever F, by which and a connecting rod H the disk D is also connected to the operating lever J.

I, Figs. 1 and 2, is a hook and eye joint.

To the bottom of the tub A, Fig. 2, is placed the bottom board L, to which the lever J is hinged at K. Two india rubber springs are placed near the joint hinge K, Fig. 2, on either side of the lever J, and secured in their places as represented.

The machine is operated by removing from the sleeve C, Fig. 1, the lever F, andv from the standard G the connecting rod, raising the disk E and placing the articles to be washed on the lower disk D, replacing the upper disk and the rod H, and lever F, and then operating the lever J backward and forward, steadying the tub if necessary by placing the foot on the bottom board L.

The violent agitation of the water caused by the opposing reeiprocative motion of the two disks, together with the rubbing of the ribs soon takes out all the dirt. The water should just cover the articles to be washed so that they will receive the full weight of the disk E, which slides up and down on the sleeve C accommodating itself to the quantity of articles to be washed. The springs M, M, Fig. 2, receive the momentum of the lever J and the two disks D and E, and rebounding communicates it to them again in an opposite direction and thus the reciprocating motion is secured with nearly the same power'that a continuous revolving motion could be.

That we claim as our invention and desire to secure by Letters Patent is Supporting the disk D, by its sleeve C, on the standard B, as and for the purpose herein set forth.
