V SPECIFICATION forming part of Letters Iatent No. 436,367, dated September 16, 1890.

Application filed April 1 6, 1 8 90- .Zo all whom it may concern:

Beit known that I, WILLIAM MANNING, a citizen of the United States, residing at Mount Joy, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Washing-Machine, of which the following is a specification.

This invention has relation to washing-machines; and among the objects in view are to provide a machine so constructed as to create as little friction as possible in its working parts and to give to the clothes a gentle rubbing not calculated to in any way injure the same.

Other minor objects of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a washing-machine constructed in accordance with my invention. Fig. 2 is a horizontal sectional View, the rubber and tub removed. Fig. 3 is a vertical longitudinal section, the tub in place. Fig. at is a detail in bottom perspective of the tub. I Fig. 5 is a transverse section of the base.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents an ordinary base or bench, which at its center is provided with a track or ring 2, surrounded at its opposite sides by curved keeper bars or guards 3, one end of one of which is eccentric with the track or ring, the companion guard being concentric or parallel to the ring.

4 represents the tub, the chines of which extend below the bottom of the tub, forming a circular recess, as is usual. Located within the recess is apair of right-angularly-disposed cross-strips 5, the ends of which are shouldered or reduced to form contact surfaces or bearings 6, and the opposite ends of one of the strips are projected beyond the exterior surface of the wall of the tub, as shown, and extend under the semicircular or curved guards heretofore mentioned.

In mounting the tub upon the track one of the extended bearing lugs or surfaces is first introduced under the guard and the tub turned until the opposite bearing-lug is opposite that end of the guard which is slightly diverged from the track or ring, after which Serial No. 348,208. (No model.)

the tub is given a partial revolution, so that both of the long bearings take undera guard and rest upon the ring or track, together with the other two bearing-surfaces of the opposite arm. Suitable lubricant is introduced upon the track and under surface of the guard, so that the tub is free to oscillate upon the ring by a mechanism to be hereinafter described. At one side of the bench is located a pair of Vertical standards 7, connected at their upper ends bya cross'bar 8, and at the opposite side of the standard, and consequently at the diametrically-opposite side of the tub, is a single standard 9, the upper end of which is reduced to form a tenon 10, and below said tenon the standard is provided with a pivoted hook 11.

Hinged to the cross-bar Sis a swinging bar 12, the opposite end of the swinging barbeing provided with an opening 13, extending above and across the tub, and having its opening adapted for the reception of the reduced. tenon 10, and at the side of the opening provided with an eye 14 for the reception of the free end of the swinging hook upon the standard 9. The swinging arm at its center is provided upon its upper and under surfaces with opposite bridges 15, the bridges and swinging barbeing provided with openings 16, square in contour and aligning with each other. Mounted for reciprocation in the openings 16 is a vertical shaft 17, square in cross-section for the major portion of its length, cylindrical at its lower end and conforming to the openings, and having secured at its lower end for rotation an inverted-U-shaped yoke 18, provided at one side with a laterally-projecting perforated operating-arm 19, and having its terminals securely bolted to a circular head 20, loosely fitted within the tub, and, like the bottom of the tub, provided with several series of variously-disposed rubbing-ribs. Upon the rear faces of the opposite standards 7 are located a pair of bearing-boxes 21,and in the same are mounted the reduced bearing portions.22 of a rock-shaft 23, provided at one end with an operating crank-arm 24. and between its bearings with a double rock-arm 25, said arm extending in opposite directions at each side of the shaft, and the upper portion of the arm being provided with a series of perforations 26.

27 represents a connecting-rod, the opposite ends of which are bent at an angle to each other, as at 28, one being designed for loose connection with any one of the perforations in the upper portion of the rock-arm and the opposite being designed for loose connection with the laterally-projecting arm of the vertical shaft 17, from which said rod may be disconnected at will. A band 28 encircles the tub near its bottom and is provided with an eye 29, which is connected to a perforation 30, formed in the lower portion of the rockarm, by means of a connecting-rod 31, the ends of which are bent, as at 32, at an angle to each other for this purpose.

The operation of my invention is as follows: The shaft 17 is first elevated within the openings 16 until the rubbing-head has been somewhat elevated above the bottom of the tub, after which the swinging arm is raised, carrying with it the head, and in this manner an unobstructed access is given to the tub. Water and clothing are now introduced in the tub and the swinging arm swung to a horizontal position, so that its opening takes over the reduced stud 10 of the upright or standard 9, in which position itis locked by means of the pivoted hook taking into the eye of said arm. The rubbing-head and its shaft are now lowered into the tub upon the clothing, and the connecting-rods 27 and 31 have their free ends inserted into the perforations or eyes formed in the lateral arm 19 and the ring encircling the tub. The operation of washing may now be begun, and simply consists in oppositely vibrating the operatin g crank-arm, and thus vibrating the rockarms or double rock-arm in alternate directions, so that as the upper end of the rockarm advances the lower end thereof recedes from the tub, and vice versa, the tub being partially revolved in one direction and the rubbing-head in the opposite direction. The weight of the shaft 17 and the rubbing-head is such as to give the desired weight upon the clothes to loosen any dirt, which is thoroughly eradicated by the movements of the tub and rubbing-head. After thewashing has been completed the swinging baris swung upwardly to an opposite position, and the clothing, together with the dirty water, removed from the tub.

From the above construction it will be apparent that I have provided an exceedingly simple and cheaply-constructed washing-machine, and one in which the most delicate apparel may be thoroughly cleansed without undue rubbing or agitation.

Having thus described my invention, what I claim is 1. In a washing-machine, the combination, with a base having a ring or track and opposite curved guards located around and elevated above the track, of a tub arranged upon the track and provided with outwardly-proj ecting bearing-lugs mounted upon the track and taking under theguards, and means, substantially as specified, for oscillating the tub, substantially as set forth.

2. In a washing-machine, the combination, with a base, a ring or track mounted upon the base, and opposite semicircular guards located at diametrically-opposite sides of the track, one of the guards being eccentric with the track, of a tub having opposite outward-projecting bearing-lugs secured to its bottom, mounted upon the track, and taking under the guards, a loose rubbing-head mounted in the tub, and means for oscillating the head and tub simultaneously in reverse directions, substantially as specified.

3. In a washing-machine, the combination, with a base, a ring or track thereon, and opposite semicircular curved guards,one of which is slightly eccentric with the track, of a tub having opposite cross-strips terminating in bearing ends and mounted upon the track, a pair of said bearingends being extended beyond the exterior surface of the tub, and means for operating the tub, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto atlixed my signature in presence of two Witnesses.

WILLIAM MANNING.
