WASHING-MACHINE.

Specicaton of Letters Patent No. 27,825, dated April 10, 1860.

To aZZ 'whom it may concern:

vBe it known that we, J. M. PATTERSON and J. F. MORELL, both of Voodbury, in the county of Gloucester and State of New J ersey, have invented a new and useful Improvement in )Vashing-Machines; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being' had to the annexed drawings, making a part of this specification, in which- Figure 1, represents a side view; and Fig. 2, a top view, of the said improved machine.

The nature of our invent-ion consists in the construction, and arrangement together, of a hollow, air-tight, corrugated, metallic cylinder, and a metallic tub or case, whose bottom itself is a corrugated concave-as hereinafter described-whereby we gain greater substantialness in the general construction of the cylinder and case of the machine, and at the same time diminish the comparative weight of the machine, and the cost of construction; and also, in the combined arrangement, hereinafter described, Y of levers, pulleys and cords, for operating the cylinder with greater facility and ease.

In the drawings, A, represents the cyliniler; and B, the concave supported upon egs.

Like letters indicate the same parts when on both figures.

The cylinder (A) is made of sheet metal, and consists of a corrugated periphery c, attached to two end-disks eZ, CZ, through the centers of which the axis e, projects. The corrugations 1 1, (shown by dot-ted lines in Fig. 1) are made in depth about one-seventh of the diameter of the cylinder (A), parallel with its axis (e), and of rounded form-as shown in the drawings. The concave (B) is also made of sheet metal, and is supported upon four legs f-f, as seen in the drawing, the corrugations 2 2, being of about the same depth and form as those of the cylinder (A), and also parallel therewith, being attached to the end plates g, g, so as to make a water tight trough, whose bottom shall be concentric with, and, about the depth of, the corrugations, distant from, the cylinder (A) when the latter is suspended upon the lower bearings 71 h, over the concave. The bearings (t-t) consist of iron pins made adjustable in height by means of the receiving sheaths i, i, md z, i', for the purpose of allowing an increased space between the corrugations of the cylinder (A) and those of the concave (B), in case an unusual quantity of clothes is required to be washed at once.

Through the space left on each side of the cylinder (B), the clothes are to be introduced into the machine. These spaces are fitted with lids, or covers, 7c, k, which are hinged to the sides of the concave (B), as seen in the drawings.

Fast on the ends of the axis (e) are two levers Z, Z, which are respectively connected to the hand levers m, m, on each end of the concave case (B), by means of the cords n, n, which pass over pulleys j, j. The opposite ends of the levers (Z, Z,) being connected, by means of the springs 0, 0, to the front legs at p, p. Attached to the levers (m, m), by means of a cord g at each end of the machine, is a vertically sliding treadle r, which works in a slot or guide s, which is formed behind each front leg (f, f,), as seen in Fig. l, which treadle gives the operator a choice to operate either by hand or foot, or with both, as may be desired. Grooved pulleys may, if preferred, be substituted for the levers Z, Z, as equivalents, or for the same purpose.

Operation: The clothes to be washed are placed in the concave (B) through either of the openings which are fitted with the hinged covers Ze, k, with the hot soap-water, and the lids or covers shut down; when, by working the hand-levers (m, m) or treadle (1"), up and down, a semi-rotary, oscillating motion will be given to the cylinder (A), and the clothes thereby rolled backward and forward, and also squeezed, between the cylinder (A) and the concave (B), in such a manner as, with the consequent agitation and surging of the water, to soften and force out the dirt, &c., from the clothes, in the most easy and expeditious manner, and without injuring the fabrics, or tearing off the buttons, as is the case in machines fitted with shallow corrugations, or grooves and ridges of wood, adapted together to produce a sliding movement of the same over the clothes.

The cylinder (A) simply rests upon its axis, by gravitation, and is therefore free to rise as the rolling of the clothes beneath it may sometimes require.

The whole machine is made either of sheet zinc, or galvanized sheet iron, excepting the springs o, o, which are made of vulcanized gum cloth, rolled up into a cylinder, its iron hooks t, t, being secured by their globular inner ends u, u, within the ends of the cylinder, by means of a wire wound around the ends of the cylinder, as seen in the drawings.

The machine is, altogether, lighter, and cheaper of construction than if made of wood; is easily operated, either by hand or foot, and is not liable to derangement.

Having thus fully described our improved washing machine, and pointed out its utility, what we claim as new therein of our invention, and desire to secure by Letters Patent, is-

l. The metallic, hollow, air tight, corrucylinder (A), and the metallic, concave and corrugated bottomed case or tub (B), the same being constructed and arranged to J. M. PATTERSON. JAMES F. MORELL.
