Letters Patent No.'105,193, dated July 12, 1870.

IMPROVED WASHING-MACHINE.

The Schedule referred to in these Letters Patent and making part o the same To all whom it may conce-'rn Be it known that I, IsAIAn W. GRAFFAM, of New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Washing-Machines, of which the following is a specification.

Nature of Invention.

My invention consists in so arranging thc handle and rubber of washing-machines that the rubber -may be adjusted by simply raising and loweringthe handie; and, in order to allow the rubber to accommodate itself to any inequaliticsin the mass of garments being washed, springs are so situated, in regard to the rubber, that it can yield to the said inequalities, and thus prevent stopping in the midst of the work.

In the drawing- Figurc 1 is a back elevation yot` my device, and

Figure 2- is a central longitudinal section.

Description.

In carrying out Amy invention, I construct a tub, wash-box, or trough, A, of any desired form, but by 'preference of that of a parallelogram, mount it on legs a a, and secure to two opposite sides of the trough pieces of wood, B B, which form bearings for rollers, b b, arranged transversely across the trough, in such a manner as to form a concave rubber, occupying the middle part of the bottom of the trough.

Standards C C are secured to the opposite sides of the trough, and extend up some distance above the level thereof, their ends forming bearings for a bar, c, from which is suspended a frame, D, which is composed of two arms, D' D', held together by a crossbar, d.

A second frame slides in guides in frame D, and consists of arms E E, carrying, at their lower ends,

the rubbingboard I, which consists of a piece of hard wood, with its under surface transversely ribbed or corrugated. rJlhis frame slides in guides formed in' the frame D.

In order to overcome any inequalities in the articles to be washed, I attach coiled springs c c, one to each of the arms E E, by one cnd, and secure the other end to a sliding bar, d', which works in grooves formed in the arms D' D'.

Set-screws F F are fitted in the cross-piece c1, and pass down through the sliding bar, so as to extend partly into the coil below, and thus steady it, and hold it in place.

At right angles to the arms D' D', I fasten short pieces or arms, H H, which project to any desired distance, and have on their ends a rod, g, which. forms an axis for handles G G.

These handles pass through openings in thearms E E, at a slight angle of elevation, and, projecting thence to near the end of the tub or trough, are joined together by a bar, g', which forms, with the other parts, the means of communicating motion to the frame D, and I call it the handleV In operation, the trough may be filled with soapsuds and water to any desired height, and the clothes placed therein on the concave rubber. The handle is raised, and lifts with it the rubbing-board. It' only a thin layer of clothes is placed on the concave, the rubbing-board frame is `lowered by turning the screws, so as to push the sliding bar down into the groove, and hold it there; and, if athick layer is to be washed, this is reversed. The frame cannot rise to the bar on account of the pressure of the springs, and, when the handle is pushed back and forth, the openings wi-ll produce an elasticity in the rubbing-frame, which will electnally prevent the clothes from being torn, and, at the same time, snicient pressure will be had to thoroughly cleanse them.

This handle serves not only to operate rubbingboard, but also to raise and lower the frame to which it is attached when it becomes necessary to do so.

By working the rubbing-board frame in guides, only aVertica-l mot-ion is allowed, and thus the action of' the board is rendered free and easy.

A faucet is placed in the trough, by means of which the water, when not-used, may be drawn olf.

Having thus described my invention,

What I claim as new, and desire to secure, by Letters Patent, is

1. The suspended swinging frame D, carrying the sliding rubber-frame Il lil I, the set-screws F, and springs c c, substantially as and for the purpose set forth.

2. The handles G, pivoted, at one end, to extensions H of the frame D, and passing through openings in the sliding frame E, so as to leave the other W'itnesses:
