SPECIFICATION forming part of Letters Patent No. 392,474, dated November 6,1888.

Application filed October .19, 1887. Serial No. 253,790. (X0 model.)

To all whom it may concern:

Be it known that I, J OSEPH H. THERIEN, of the city and county of San Francisco, State of California, have invented an Improvement in WVashingMachines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in machines for washing clothes.

It consists of an inclosing outer cylinder formed of staves which are beveled, inclined, or so fitted as to form ledges in the interior, acylindrical drum rotating within the exterior casing, said drum being formed of peculiarlyshaped bars or slats, and devices for turning and spreading the contents of the cylinder are fixed within it, together with certain details of construction, all of which will be more fully explained by reference to the accompanying drawings, in which- Figure l is an exterior perspective view of the machine. Fig. 2 is a transverse vertical section. Fig. 8 is a view of the dischargevalves. Figmiis an enlarged detailed sectional view showing the slots between the bars 1) and the pins or studs projecting therein.

A is the exterior drum or cylinder, which is made of staves. These staves are secured together by bands or hoops around the outside, and have their inner surfaces beveled or so placed with reference to each other as to form a series of steps or notches, a, which operate in conjunction with the interior rotating cylinder, as will be hereinafter described.

The outer cylinder, A, is stationary and supported by suitable standards or feet. Within this cylinder and concentric to it is the inner rotating drum or cylinder, which is composed of two end disks, 0, having the longitudinal bars or strips D extending from one end to the other and parallel with each other, their ends being secured to the disks. To each of these cnd disks is secured a short shaft or journal, which projects outward and is supported in proper boxes at the ends of the outer case. One of these shafts projects through and may have a crank, E, fixed to it by which the drum is rotated. The bars I), which form the circumference of the inner rotating cylinder, are triangular in cross-section, having the two sides meeting at a right angle, which angle extends radially toward the center of the drum, and the hypotenuse or longer side forms the flat outer side of the cylinder. These bars D are set at short distances apart, so as to leave a space between them. This space is formed as follows: One of the sides 4 of each of the triangular bars continues in a plane from the inner angle to the outer one, while the other side, (1, has its outer angle cut off, as shown at (1 so that this portion stands parallel with the side D of the next adjacent bar, and thus forms a narrow inclined slot between the two.

XVhen the drum is rotated in the direction shown by the arrow, the body of water containcd within the outer case is retarded in its movement by the angular stops or projections a, and this forms a sort of draft or suction through the inclined slots formed between the bars D I), so as to continually draw the water, and with it the dirt which is loosened from the clothes, through these slots in the lower part of the cylinder or case as the inner drum is revolved.

Pins or nails with enlarged heads are fixed in the slots to prevent small articles from passing through.

In order to prevent the clothes which are within the drum from rolling up and becoming a solid mass I employ spreaders. These sprcaders consist of arms F, which are fixed diagonally upon opposite ends within the revolving drum, so that they extend from the end disks at points near the center downward and outward against the bars D. One of these arms F extends downward near the inner face of the end disk, the next one stands ata little greater incline, overlapping the first one, and the third one stands at a still greater incline, overlapping the second, and in the same manner for four, five, or morc,if so many be used. They are also split ordivided by slots extending from their outer ends toward the center, as shown. In the present case I have shown two of these sprcaders standing opposite each other upon the inner ends of the revolving drums, and the clothes striking against these are rolled outwardly, so as to counteract the tendency to roll up into bunches. This keeps them open and spread out,so that they will be thoroughly acted upon by the water and soap contained within the machine, and the vacuum or sucking action caused by the slots between the bars will thoroughly cleanse them of dirt. The outer case has a cover, G, hinged near the 5 top and extending along the side, and the inner one has a section, H, composed of bars which form its periphery hinged in the same manner and provided with locking bolts or devices at the ends, whereby it may be kept IO closed when in operation.

When it is desired to open the inner case and remove or inspect the contents, it is done by bringing the hinged section II opposite the hinged outer cover, G, when both may be opened and the contents removed or placed in the machine.

I is a table hinged to the side of the outer case at the lower edge of the opening which is closed by the cover G. This table has up weirdly-projectingsidesJ, and also has abrace or arm,K,by which it is held when turned up so as to have an incline toward the interior case. The wringingmachine may then be secured to one side of the table I, and the clothes being removed from the machine and run through the wringer,the water will run back upon the table I, and by reason ofits incline will pass into the machine. Atthe bottom of the outer chamber, A, are openings through which the 0 water is discharged at will. These openings are closed by valves L, fixed upon the leverarms or bars M, which are fitted together by a transverse bar or red, N, having a handle, 0, by which it may be operated, so as to open or close the valve simultaneously. This framework slides over guides P at the bottom of the frame supporting the chamber A, and the uppersurfaces of these guides areinclined, so that as the valves are brought over the holes of the discharge-openings the inclined guides force them up, so as to make a tightjoint. In the same manner when theyare to be opened they move down these inclines, so as to be released to open freely.

5 Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

1. A. washing-machine consisting of an extc rior cylindrical casing formed of staves, the interior surfaces of which are inclined so as to form stops or offsets a, extending transversely across the ease, in combination with an interior drum revolving concentrically and with its periphery in close proximity to the interior of the case, the bars composing the periphery of said drum being triangular in crossseetion, and having one exterior angle cut off parallel with the adjacent side of the next bar, so as to form channels between the bars which are not radial to the center of the drum, substantially as herein described.

2. The triangular bars forming the periphery of the interior revolving drum and fixed in the end disks, so that the outer and longer sides of the prisms form the smooth exterior surface of the drum, while the interior angles are presented radially toward the center of the drum, said triangular prisms having one exterior angle cut off, so that the resulting face lies parallel with the continuous side of the next adjacent prism and forms a channel which is tangent to an interior cylinder of smaller diameter, in combination with an exterior stationary case within which the cylinder revolves concentrically, the interior of said case being formed with inclines or offsets, substantially as herein described.

3. The exterior stationary case and the interior revolving drum constructed as described, in combination with the spreaders formed of inclined bars fixed within the ends of the drum and extending from its center toward the periphery and diagonally away from the ends, said bars overlapping each other, substantially as herein described.

4.. The exterior case and the interior cylinder or drum having the longitudinal peripheral slots, in combination with the pins or studs projecting into said slots, substantially as and for the purpose herein described.

In witness whereof I have hereunto set my hand.

JOSEPH H. THERIEN.
