HOWARD A. sHAW, or GALENA, OHIO.-

WASHING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 253,433, dated February 7, 1882.

' Application filed September 30,1880. (ModeL) To all whom it may concern Be it known that I, HOWARD A. SHAW, a citizen of the United States, residing at Galena, in the county of Delaware and State of Ohio, have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in washing-machines; and it consists in a rubber composed of a series of'parallel bars held on cross-rods, the two outer being held loosely in place and having rubber cushions placed between them and the next inner bars, all of which will be-hereinafter more fully described.

In the drawings, Figure 1 is a plan, and Fig. 2 is avertical longitudinal section, of a machine containing myimprovements; and Fig. 3 is a plan view of my improved rubber.

cross-rods d placed near their ends.

(1 is the rubber, which is composed of a series of flat bars, 61 d, preferably four in number, arranged equidistant apart and held by The bars d d are set on their edges and are fixed to the cross-rods d excepting that the outer bars slide inwardly on the said rods, as I will now explain. The two outer bars are placed loosely on the end rods, (1 and are held by any suitable means, so that they will not slip off, but can slide freely inward toward the next bar, 01 On the rods d, I place elastic cushions d between the endsof the outer bars, 61 and the ends of the next inner bars, (1 The cushions hold the bars d outward flush with or near the ends of the rods d and at the same time yield under pressure and permit the said side bars to be forced back on the said rods. In the movement of the rubber over a series of rollers in or corrugated surface on the wash-board, the side bar in advance, when the rubber is moved in any given direction, will have a vibratory or back-and-forth movement on the rods d which vibratory motion greatly facilitates the washing of the clothing, especially of small articles.

In order to fully illustrate myimproved rubher, I have shown it as attached to the machine hereinafter described. The construction of this machine, however, and the mode of attaching and operating the rubber are not new.

The rubber is fixed on the lower endof an oscillating arm, d, which is supported at or near its middle on a cross-bar journaled in a hinged frame, a, by means of which it is raised or lowered to adaptit to the different bulks of clothes in the suds-box.

a is the suds-box, containing the concave wash-board b. The frame 0 has one of its ends pivoted to the suds-box, while is other end passes back and has a free vertical motion over the front end of the suds-box. The upper end of the arm d is connected by rod e to crank e, fixed to shaft 6 which is so connected by crank 0 pitman c and crank e to crankbandle 6', all of ordinary construction, as to give proper oscillatory motion to the rubber arm (I in the operation of'the machine.

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

In a washing-machine, the rubber d composed of a series of parallel bars, (1 d arranged and held on cross-rods d the bars (1 being placed and held loosely, so that they slide inwardly on the said cross-rods, the elastic cushions d, placed on the rods d between the outer bars, 01 and the next inner bars, d, and secured on the lower end of an oscillating arm, d, and operated substantially as and for the purposes set forth. t

In testimony whereof I affix my signature in presence of two witnesses.

HOWARD A. SHAW.
