SPECIFICATION forming part of Letters Patent No. 388,996, dated September 4, 1888.

Application filed May 5, 1887. Serial No. 237,214.

To ctZZ whom it; may concern.-

Be it known that I, ALoIs MUELLER, of Neillsville, in the county of Clark and State of Wisconsin, have invented a new and Improved Combined Washing Machine and Boiler, of which the following is afull, clear, and exact description.

My invention relates to the construction of an improved wash-boiler and washing-niachine combined in one, and has for its object to render the same simple and strong in construction, convenient in use, and extremely effective in operation, while very easy upon the clothes treated.

To this end the invention consists in certain novel features of construction and combinations of parts, as hereinafter fully described, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specificatiomin which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan of my combined washing machine and boiler, the upper boiler-section being raised to show the washing-cylinder in position. Fig. 2 is an end elevation of the same. Fig. 3 is a cross-section of the machine, showing the upper boiler-section as closed. Figs. 4., 5, and 6 aredetail views hereinafter more fully described.

A designates the lower section, and B the upper section, of which the boiler of my improved machine is composed.

The lower section, A, is formed at its lower part into a flat-bottomed rectangular box, A, adapted to rest upon the top 0 of a stove or heater, and which may be depressed at its middle part, as shown, similarly to the ordi nary wash-boiler, to fit the openingin the top C, as in Fig. 3. The upper portion, A of the lower section, A, is semi-cylindrical in form, and, in conjunction with the upper semicylindrical section, B, hinged thereto, forms a cylindrical casing to completely iuclose the washing-cylinder. Cast-metal frames D and E extend completely around the meeting edges of the lower and upper sections, A and B, respectively, and are secured thereto so as to strengthen and stiffen the sheet metal of which they are made. The hinges E of the (No model.)

sections directly connect these frames, with which they may be cast integrally, if desired. A deep groove, D, is cast in the upper side of the lower frame, D and extends around the same to receive a rubber or othersuitable packing, and a corresponding tongue, E, is cast on the lower side of the upper frame, E, to fit in the groove D, compress the packing therein, and thereby form a perfectly steam and water tight joint, as shown in cross-see tion in Fig. 5.

The upper and lower frames, E D, are cast at their ends with corresponding half-boxes, E D", which form when the boiler is closed steam-tight bearings for the journals F F of the washing-cylinder. When the washingcylinder is not in use,the holes left in the sectional end bearings are tightly closed by headed plugs G, having their heads on the inside, as in Fig. 6, so as to prevent their being blown out by the pressure of the steam. Studs Hare cast upon and project from the front of the upper frame, E, in position to be engaged by strong metal clasps H, hinged to the lower section near its ends, so as to keep the boiler closed against the pressure of the steam.

The clasps H are bowed sharply outward just above their respective hinge-joints, so as to set over and closely embrace between the ends of the bow the two meeting frames D, and thus additionally secure them against ac cidental separation.

Crooked handles I project outward and downward from the front of the lower cast frame, .D, near the ends of the same, and on the rear of said frame D similarly-arranged handles J are formed integrally and continuously with rearwardly-inclined legs K, which prevent the machine from being overbalanced when the upper section, B, is raised, as in Fig. 2. By means of the opposite pairs of handles I and J the whole machine may be readily carried from place to place. Crooked arms LL project centrally from the front and rear, respectively, of the upper frame, F, the front arms, L, serving as a handle for raising and lowering said section, the rear arm, L, serving as a stop to prevent the section from falling back too far. A cock, M, of the ordinary description, is inserted in one end of the lower part of the boiler for drawing off the water, as when it is desired to move the machine.

Combined safety-valves and steam-whistles N, of the usual description, project from the top of the upper section to signify and afford relief for excessive steam-pressure.

The washing-cylinder employed in conjunction with the sectional boiler above described is of peculiar construction, having its heads 0 and cylindrical side wall, P, formed of sheet metal suitably secured together and strengthened and punctured or depressed from the outside to form numbers of spherical prominences on the interior of the cylinder.

A number of spherical washing-bolts like the bolt 0, (shown in Fig. 3,) havingan indented or fluted surface formed by cutting two series of grooves at right angles to each other, and each series extending entirely around the bolt, are placed in the Washingcylinder with the clothes, and cooperate with the spherical prominences on the interior of the cylinder so as to thoroughly rub the steam and water into the clothes without injuring the same.

Series of longitudinal slots Q are cut in the wall P of the cylinder, and series of radial slots R in the heads thereof, and the metal at one side of said slots presses outward, so as to form inclined chutes leading to the interior of the cylinder. The chutes Q, thus formed in the wall of the cylinder face in an opposite direction to the chutes R, formed in the heads of the cylinder, so that when the cylinder is revolved the scalding water and steam pro duced within the boiler will be forced into the cylinder through the chutes Q in its wall and ejected from those in its heads, or vice versa, according to the direction of rotation of the cylinder, so that a constant and rapid circulation of steam and scalding water will be maintained through the cylinder and the clothes therein.

The longitudinal chutes Q in the side wall of the cylinder are arranged in parallel lines about the cylinder, the lines consisting alter nately of a single chute of about half and at the middle of the length of the cylinder, and a pair of chutes, each extending from behind an end of the single chute to within some distance of the corresponding end of the cylinder. The radial chutes in the heads of the cylinder are much wider at their outer ends than at their-"inner ends, their sides being on radial lines having the same center as the cylinderheads.

To strengthen the sheet-metal heads of the washingcylinder, solid star-like castings F are soldered or secured centrally thereto, with their branches severally radiating between the radial slots R to stiffen the chutes formed thereat, and with the castings F are formed integrally the before-mentioned journals F F oi the cylinder. An opening is formed in the wall P of the cylinder, extending the length thereof, for the introduction and removal of the clothes and bolts, and at the sides of said opening are provided parallel grooved guides S, in which the door S is mounted to slide, said door being peculiarly formed like the rest of the cylinder.

The door S is formed with an apertured boss, S to receive a hook for adjusting the door, and an ordinary catch, S is pivoted to the left-hand cylinder-head, Fig. 1, for engaging the end of the door and holding it in place. The right-hand cylinder-head extends outward to the guides S, and serves as a stop to limit the movement of the sliding door in that direction.

The journal F is provided with a crankhandle, F for revolving the cylinder, and the journal F with a spherical head to prevent its catching and tearing the clothes. With this construction a perfectly steam and water tight boiler is produced, by which the water and steam can be raised to a temperature above the ordinary boiling degree,so that the clothes, being subjected to the rubbing action simultaneously with the constant circulation of such highly-heated water and steam, as described, are quickly and thoroughly cleaned without incurring the slightest injury; also, in simply boiling the clothes the washing-cylinder being removed, the same advantages of high temperature are secured,while the scalding water 5 is effectually prevented from splashing out, as in the case of the ordinary boiler, and the water can be quickly drawn off through the cock, so as to permit the entire machine to be moved about. Further, from the shape of the boiler it is rendered as portable as the ordinary plain wash-tub, while from the cylindrical shape of its upper part it is not only adapted to receive the washing-cylinder, but is enabled to hold a much larger quantity of water, and hence possesses a much greater capacity than the usual form of boiler.

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