WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 721,929, dated March 3,1903.

Application filed June 9, 1902. Serial No. 110,725. (No modali' To all whom, t mfc/,y concern:

Be it known that I, FREDERICK H. WIAED, a citizen of the United States, residing at East Avon, in the county of Livingston and State of New York, have inventedv newrand useful Improvements in Washing-Machines, of which the following is a specification.

This invention relates to that class of washing-machines which comprise an oscillating tub provided in its bottom with ribs or corrugations forming a lower rubber and an upper oscillating rubber arranged; above the lower rubber and carried by a support which extends upwardly through the bottom of the tub as distinguished from machines in which the upper rubber` is suspended from' a crossbar extending across the top of the tub.

The object of my invention is to produce a machine of this type in which the two rubbers are simultaneously o'scillated in opposite directions and which shall at the same time be strong, compact, and inexpensive in construction.

In the accompanying drawings, consisting of two sheets, Figure l is a'sectional side elevation of my improved washing-machine. Fig. 2 is a horizontal section thereof in line 2 2, Fig. l, looking upward. 1 Fig. 3 isafragmentary vertical section of the machine on an enlarged scale. Figs. 4, 5, and 6 are transverse sections in lines 4 4, 5 5, and 6 6, Fig. 3, respectively.

Like letters of reference refer to like in the several figures.

The stationary base or supporting frame of the machine preferably consists of a metallic parts head or crown plate A, provided on its underV side with a number of sockets a, preferably four, and a corresponding number of legs A', having their upper ends secured in said sockets. These legs are tiedl together below the plate A by a brace or bridgetree A2.

B is the oscillating tub, which is provided in its bottom with ribs b, forming the lower rubber.

C is an upright cylindrical rock shaft which turns in bearings c c', formed centrally in the plate A and the bridgetree A2 and which passes loosely through an opening in the bottom of the tub. The latter is preferably supported on ball-bearings, which comprise an" inverted annular cup d, arranged on the under side of the-tub, a collar d', arranged below said cup, and a row of balls cl2, interposed between said cup and the upper side of said collar, as shown in Fig. 3. The collar d rests upon the hub of a horizontal gear-segment E, which is secured to the rock-shaft C, and this segment is in tu rn supported by a ballsbearing, which consists, preferably, of an inverted cup 6o e, arranged on the under side of said gearsegment, 'a collar e@ resting upon the bearing c, and a row of balls e2, interposed between said cup and the upper side of said collar. The bearing-cups d e and the collars d' e' are arranged loosely on the rock-shaft C, and the upper cup d is caused to turn with the tub by a stud cl3, arranged on the under side of the tub and entering a recess in said cup, or by other suitable means. The lower 7o cup e and the upper collar d are caused to turn with the gear-segment E by similar studs e3, while the lower bearing-collar e' is held against turning by a stud e4, which enters a recess in the bearing-c. The tub is provided at its upper edge with a handle f for oscillating it.

G is a horizontal rock-lever arranged below the tub and mounted upon a vertical pivot g, which projects from the upper side of the 8o plate A. This lever is provided at its inner end with a gear-segment g', which meshes with the gear-segment E of the shaft C, and the outer arm of the lever .passes loosely through an opening h, formed in a depending bracket H, which is secured to the lower edge of the tub, so that upon oscillating the tub the shaft O is rocked or oscillated in the opposite direction from the tub through the medium of the rock-lever G and the gear-seg- 9o ments E and g.

l is the upper rubber', which coperates with the lower rubber b, carried by the tub. This rubber consists of a disk which is provided on its under side with rubber ribs i and which is adapted to turn with the rockshaft C, so that the upper and lower rubbers are oscillated in oppositedirections.

`J is a cross-head arranged above the upper rubber and provided with a central opening, loo through which the rock-shaft C passes loosely, and K represents vertical tie rods or bolts which connect the upper rubber with said cross-head. The upper ends of these rods pass through the ends of the cross-head J, and their lower ends are secured in perforated horizontal lugs Z, secured to the upper side of the upper rubber and overhanging the edge of an opening Z', which is formed centrally in the rubber.

m represents spacing tubes or sleeves which surround the tie-rods K between the lugs l and the under side of the cross-head J.

N is a second cross-head, arranged below the cross-head J and secured to the rock-shaft C, so as to oscillate therewith. This oscillating cross-head is provided in its ends with notches or recesses n, in which the spacingtubes rn of the upper rubber engage, as shown in Figs. 3 and 5. By this construction said tubes are interlocked with the cross-head N, compelling the same and the upper rubber I to oscillate therewith, while at t-he same time allowing said tubes to slide vertically in the recesses of said cross-head to permit the upper rubber to be raised for placing the clothes in the tub. The upper cross-head J, the tie-rods K, and the spacing-tubes m together form a rigid and inexpensive supporting-frame for the upper rubber I.

ois an upright tube or sleeve extending upwardly from the bottom of the tub B and surrounding the rock shaft C, forming a housing therefor. This tube is secured at its lower end to the tub-bottom in any suitable manner to form a water-tight joint, and its upper end is seated loosely in a socket o'-, formed in the under side of the said crosshead N, so that the tube is free to oscillate with the tub independently of said crosshead.

p is a cover for the tub, which rests upon suitable ledges p' and which is provided with a central opening for the passage of the rockshaft C and the upright supporting-frame of the upper rubber I.

The central opening Z of the upper rubber `is of sufficient size to admit the oscillating cross-head N, and the recesses 'n of this crosshead are of the proper size to permit the passage of the lugs Z. through the same, so that the upper rubber can be passed over the central shaft C and the tube 0 or removed therefrom.

In using the machine the coverp and the upper rubber I are removed from the tub, and after placing the clothes in the same said rubber and the cover are replaced. The tub is then oscillated by grasping its handle f, the movement of the tub being transmitted to the upper rubber I by the rock-lever G, the gear-segments E and g', and the rockshaft C in such manner as to oscillate the two rubbers in opposite directions, as hereinbefore described. This action ofthe rubbers is produced by simple means and without the necessity of extending a cross bar or yoke across the top of the tub.

I claim as my inventionl. The combination with a stationary frame, and an oscillating tub supported thereon and provided in its bottom with a rubber, of an upright rock-shaft journaled in the stationary frame and extending upwardly through the bottom of the tub, an upper rubber connected wit-h said rock-shaft to turn therewith, a horizontal rock-lever arranged below said tub and connected with the tub to oscillate therewith, and means connecting said rock-lever and rock-shaft whereby the shaft is rocked in an opposite direction to that of the tub, substantially as set forth.
