JOHN GRAY, OF MELROSE, NEW YORK, ASSIGNOR TO HIMSELF, AND J. R. WEED AND C. M. CT,AV, OF NEW YORK, AND J. W. DANFORD, OF BROOKLYN, NEW YORK.

WASHING-MACHINE.

Specification of Letters Patent No. 30,375, dated October 9, 1860.

To all whom it may concern:

Be it known that I, John Gray, of Melrose, in the county of Westchester and State of New York, have invented, made, and applied, to use a certain new and useful Improvement in Washing-Machines, which I denominate the “ Metropolitan washing-machine ; ” and I 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 drawing, making part of this specification, wherein—·

Figure 1, is a plan of my said machine and Fig. 2, is a vertical section of the tub and side view of the center drum.

Similar marks of reference denote the same parts.

The nature of my said invention consists of a revolving cylindrical drum with slats set at an angle to the axis of said drum so as to throw the water off by the centrifugal force at the same time that the inclined slats tend to elevate the water, this drum being combined with a conical tub, the inner surface of which is fitted with inclined ribs standing in the same direction as those on the drum, but being stationary, the water in its agitated and revolving movement from the revolution of the drum, runs against these inclined slats producing a downward current against the edge of the tub: the consequence is that the clothes lie in and revolve with a ring of water, and that there is the most violent rinsing of the water through the clothes by the centrifugal force on the surface and the under return current to the drum induced by the inclined slats on the tub.

In the drawing a, is the tub the sides of which are inclined or conical, b, b, are cleats or ribs set at an angle of about 6° from the vertical line and attached permanently around the inside of said tub; c, is a cross piece carrying the shaft d, on which is fitted the handle e, and bevel gear f to the bevel pinion g on the shaft h, of the drum i. This drum is formed with two circular heads 1, 2, connected by the slats or rods 3, 3, that set at an inclination to the shaft Λ, of about 6°, as shown in Fig. 2. The head 2, is elevated slightly from the bottom of the tub a, to allow for a step that receives the lower end of the shaft /i, as shown by dotted lines in Fig. 2, but the slats 3, 3, extend to the bot- 55 tom of the tub or may even set into a circular groove in order that the clothes may not become entangled and wound around the drum.

The cross piece &lt;?, is fitted so that it can 60 be removed if necessary and the drum taken out, but this is seldom if ever required as I form all the metallic parts of brass or other metal that will not corrode or require cleaning. _ 65

The operation of my machine will be apparent from the foregoing description, and I have represented the currents produced in the water by blue arrows, the direction in which the drum i revolves being denoted by 70 the black arrow on it. My machine is simple, cheap, durable and efficient, and is not liable to injure the clothes.

The operation of cleansing is wholly effected by the force of the water through, and 75 the agitation and current above and underneath, there being no rubbing, scouring or compressing of the clothes to wear them or break off the buttons or tear tender fabrics; the power only required to operate it, being 80 necessary to agitate the suds or water, and that, soon assuming a circular current with the motion of the drum assists to make the operation easy rather than to retard its action. 85

I do not claim the conical tub having inclined cleats or ribs on the inner surface nor
