SPECIFICATION forming part of Letters Patent No. 441,523, dated November 25, 1890.

Application filed June 6, 1889. Serial No. 313,408. (No model.)

To all whom it may concern:

Be it known that I, DAVID D. WnlsELL, of Fort Vayne, in the county of Allen and State of Indiana, have invented a new and useful Improvement in Washing-Machines, of which the following is a specification.

My invention relates particularly to that class of machines known as rotary-rubber washing-machines, and has for its object to provide a machine which will quickly and efficiently perform all the various operations of Washing by hand-namely, rubbing, pressing, and rinsing; and with these objects in view it consists of a tub or other receptacle having a concaved false bottom, aself -adj usting conical rubber revolving above the concave bottom, and suitable gearing for operating the rotating rubber.

It consists, further, in certain details of construction and combination of parts, as will be more fully hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure l is a vertical longitudinal section. Fig. 2 is a top plan View. Fig. 3 is a detail sectional view of the convex rubber and driving mechanism. Fig. e is a partial plan view of one form of false bottom. Fig. 5 is a sectional View of another form of false bottom. Fig. 6 is a perspective view of a portion of the convex rubber. Fig. 7 is a detail view of the supporting-casting. Fig. 8 is a detail View of a portion of the false bottom, and Fig. 9 is a detail sectional view of a portion of the convex rubber.

In carrying out my invention I employ a tub Vor other suitable receptacle A, mounted upon legs B, said legs being held rigid at their points of connection to the tub by the sockets V. The lower ends of the legs may be braced in any suitable manner.

Vithin the tub A is placed a concaved false bottom C, said bottom being preferably removable, and consists of a base supporting a series of radially-extending ribs. This base may consist of 'cross-bars D D, provided with the band E, as shown in Fig. 4, or it may be a metallic frame-work, both of which are hereinafter described, or it may consist of any other suitable means for supporting the ribs readily upward-and outward, so as to form a false concave bottom; but in constructing the arranged opposite the radial bars or webs G.

Upon the upper faces of the rings F F are formed a series of upwardly-extending lugs f f and between these lugs are formed the apertures f2. The radial ribs a, which form the concaved bottom, are tapered, as shown,

so that they can fit snugly between thev lugs f f and they are secured in these positions by screws or nails passed through the apertures f2 from the under side of the rings. AThe upper faces of the ribs are provided with a double bevel or incline, the purpose of which will appear farther on. cured in such a manner as to leave a circular opening at the center, which is intended to fit over a circular block H, rigidly secured to the bottom of the tub, the upper face of said block being corrugated, as shown. The ribs are sufficiently separated from each other/to permit the dirt and sediment to pass between The ribs a are sethem, and to draw the same off the tub is provided with an opening near its bottom, said opening being normally closed by a plug. Upon the inner side of the tub are secured a series of vertical cleats or ribs b, extending from the top edges nearly to the bottom-of the tub, said cleats being doubly7 beveled or inclined and so arranged as to pass l.between the outer ends of the radial ribs, thereby pte-ffl venting the concaved bottom from rotating Although Iprefer to use a false bottom `con structed as described, other constructions structed similar to those already described,- the inner ends being nailed or screwed to.

the cross-bars and their outer edges to the band E.

In Fig. I have shown the radial ribs secured directly to the bottom and sides of the tub, the inner and lower ends of the ribs beingsecured near the center of the bottom of the tub, and the upper and outer ends being secured tothe sides of the same at a point sufficiently high to permit the water to circulate freely thereunder, and it will readily be seen that when the water is thrown outward by centrifugal force it will have sufficient space to acquire considerable force, whereby the tendency will be to pass entirely through the mass of clothing held upon the bottom, thus assisting in cleansing the same. The outer ends of the ribs being secured above the bottom, the sediment can be easily removed by simply filling the tub and operating the agitatorrubber.

In connection with my improved concaved bottom I employ an inverted conical rubber made to conform to the angle of the concave bottom, said rubber being formed of a series of upwardly-extending radial ribs a', secured to a suitable casting 1, said casting consisting of the central circular portion 2 and fiat concentric ring 3, said ring and central portion being connected by suitable braces or webbing 4. Upon the under side of the flat ring Bare cast a series of depending lugs g, and on the under side of the central portion 2 are cast a similar number of depending lugs e. Vithin the circular space left between the lugs c is secured a circular blade L, corrugated on its under surface and having its periphery beveled or outwardly inclined. The radial ribs a', constructed similar to the ribs u, are secured to the casting l between the lugs c and g, their inner ends lying in close contact with the beveled sides of the corrugated block L.

In Fig. 6 is shown a modified form of rubber, consisting of a circular conical block K, beveled outward and upward from its lower surface, said beveled surface being preferably provided with a series of radial grooves 7c, in which fit tongues formed upon the upper faces of the radial ribs a. The grooves may be omitted from the block K and the tongues from the ribs, and the ribs nailed directly to the block.

Upon the upper face of the central portion 2 of the cast-ing 1 is formed a short vertical sleeve M, and within this sleeve is held the shaft I, which supports and operates the rub' ber, the lower end of said shaft being covered with elastic tubing and held within the sleeve M by a pin t' passing through them. The rubber tubing is placed around the end of the shaft I for the purpose of making a flexible connection between the shaft and rubber and to relieve the sudden jar occasioned by the reciprocation, which in time greatly impairs machines having rigid connections at this point.

In the rubber illustrated in Fig. 6 the shaft I is inserted in a cross-block K secured to the upper face ofthe circular block K. The upper rim of the tub is rabbeted to receive the cover of the machine, said cover being usually formed of three portions, the fixed

side portions

22 and 23 and the central portion 24, said central portion being strengthened by transverse bars m m in order to sustain the weight of the gearing which is attached to this portion of the cover. The cover 24 is hinged to the stationary part and locked when closed in any suitable manner.

At the center of the detachable cover is secured the driving mechanism, said mechanism consisting of the vertical standard O, the bevel-gear R, and mutilated bevel-gear P, connected with the hand-lever S. The standard O consists of the base-piece 5, having the threaded bolts 6 and 7 depending from its lower face near each end of the same, and at the center of the base-piece is formed thimble or sleeve 12, contiguous to a circular aperture made in the base-piece, said sleeve depending a sufficient distance to pass through the cover and serve as a bearing for the vertical shaft I, which passes through the same and carries the rotary rubber at its lower end. The bolts 6 and 7 also extend through the cover and at the lower ends are threaded to receive the nuts 15 and 1G, which bind the standard to the cover 24.

Connected to the base-piece 5 at each end are the laterallyprojecting bracing lugs or feet 13 and 14, and extending upwardly from the base are the converging arms 9 10, said arms meetinga short distance above the base, and at their juncture is formed a circular aperture 17, said aperture being in alignment with the aperture made in the base and adapted to serve as a bearing for the upper portion of the shaft I. At the juncture of the up right arms is cast the laterally-projecting spindle 18, said spindle being arranged at one side in a plane at right angles to the plane of the standard O.

Between the base-piece 5 and the arms 9 and 10 is arranged the bevel gear-wheel R, said gear having formed on its upper face a vertical sleeve or tube T, extending to the juncture of the arms 9 and 10 and slotted vertically on both sides, the slot-s extending from the bottom of the tube to a point near the top of the same, and at the ends of these slots are formed the horizontal lugs Z l. The bevel-gear is held between the arms of the standard by the vertical shaft I passing up through the same, and to hold the shaft within the tube and support the same a pin or key a is passed through the shaft, said pin working in the slots cut in the sleeve T.

Mounted upon the spindle 18 and meshing with the bevel-gear R is the mutilated gear wheel P, said wheel being constructed of a concave-convex form, as shown, the teeth being arranged upon the convex face, and to the concave face is secured the hand -lever S, the lower end of said lever being fitted ina socket formed between two of the spokes near IOO IIO

the hub of the wheel, and on the rim of the wheel are formed two parallel lateral ears, be-

tween which the central portion of hand-lethis flattened end is passed a washer 19, having an aperture shaped to correspond with Io the flattened end, said washer being held upon the spindle by a linchpin passing through the same. In this way the wheel P is secured to the spindle. If the Weights of the vertical shaft and attached rubber are not sufficient to press the clothes as desired, I aid such pressure by using a spiral spring encircling the vertical sleeve, one end opposed to the lugs on the upper part of the sleeve and the other against the pin attached to the vertical shaft, adapted to press the pin with itsl attachments downward. I also show the basepiece 5 cast integrally with the arch-frame. This is a preferable construction, but not a necessary one, for the base-piece may be separate and attached suitably to either the arch or lid, orto both, as may be desired. The upperend of the shaft I is provided with a ring or handle h for raising the conical rubber when closing the cover, so as to prevent the rubber from dragging the clothes to one side .of the tub. At one side of the tub a few staves are extended beyond the rim of the tub to form a stand for a wringer. (Not shown.) Upon the interior of the tub, at any desired height, is branded or otherwise marked a horizontal line and designated water-line, the purpose of which will -appear at once.

From the above description it will be seen that a machine is constructed which is simple, durable, and efficient, and one that is not at all likely to get out of order. The gearing being supported by a single standard O, it is not liable to be thrown out of engagement by the warping of the cover, as is frequently the case with machines having two or more supporting-standards. The operating mechanism of the machine being held by the single standard, I am enabled by removing the lever and cone-rubber to pack the entire driving mechanism, together with the lever and legs, within the tub, thus. securing it from breakage in transportation or storage.

The driving-wheel is constructed with a concave face, so that the end of the operatinglever S is thrown outward toward the edge of the tub and brought within easy reach of the operator.

Having fully described the construction of the various parts of my machine, I will now proceed to describe the manner in which they are operated. The bottom C having been placed within the tub A, the clothes are put in and the tub sufficiently filled with water to reach the waterline. The cover carrying the rotating rubber and driving mechanism is then closed and suitably secured in its closed position, the conical rubber being held -up by the ring hf to prevent the clothes being dragged to one side of the tub. The moment the ring h is released the spring s forces the conical rubber down upon the clothes and keeps it there during the operation. The hand lever is then oscillated, each oscillation ot' the lever making about one and a half revolution for the rotary rubber, andthe direction that the water is thrown by the centrifugal force of the rapidly-revolving rubber is deflected by the beveled or doubleinclined ribs to a direction directly through the massof clothing and between the ribs of the concave bottom, carrying with it the loosened dirt to thebottom of the tub, and

when the washing process is completed it is drawn off through thev opening. The resistance offered by the corrugated concave bottom to the free movement of the clothes tends to bunch them in the center of the tub at the end of each revolution of the rubber, and the act-ion of the spiral spring presses or squeczes the water partially out of them at this point. The reverse motion relieves the bunching and admits the water again, to be pressed out at the end of this revolution.

Having thus described my invention, what I claim as new is I. The combination, with the tub, of the concave false bottom arranged within the same and resting loosely on the bottom, and consisting of a base-piece and a series of independent radiating ribs secured upon the base and projected upward land outward therefrom, and the convex rotary rubber mov` ing over said false bottom, as set forth.

In a vwashing-machine, the combination, with a tub cr box, of a concave false bottom consisting of a series of independent ribs radiating from the central part of the bottom of the tub to the sides of the said tub, suitably lsecured and arranged with spaces between them, and placed at such an angle that the ribs touch only the bottom with their inner ends and the sides with their outer ends at a point above the bottom of the tub, substantially as and for the purpose described.

3. The combination, with the tub, of the false bottom resting loosely Within the same, and consisting of a series of independent ribs a, radiating outward and upward from the center, the rubber rotating over said false bottom, and the vertical ribs secured to the inner side of the tub and fitting between the ends of the ribs a to prevent the bottom rubber from rotating, substantially as set forth.
