JAMES G. CRAWFORD, OF BOSTON, MASSACHUSETTS.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 235,073, dated December 7, 1880.

Application filed July 26, 1880.

To all whom it may concern:

Be it known that I, JAMES G. CRAWFORD, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Washing-Machine, of which the following is a specification.

In this improvement the dasher is constructed with corrugated sides and has stationary vertical paddles or partitions, and the tub holding each dasher is provided with a bonnet adapted to prevent small garments, such as collars, 850., from dropping into the space between the tub and dasher. The corrugated sides of the dasher increase and give greater variety to the motion of the water. The mechanism for operating the device is fully described below.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l is an elevation of myimproved machine carrying two tubs. Fig.2 is aplan view with a portion of the bonnet removed from one tub and the second tub removed. Fig. 3 is an enlarged plan of a tub with a portion of the bonnet removed. Fig. 4 is a vertical section of a tub.

a is the frame supporting the tubs b b, of which there may be any number. Within each tub b is a dasher, 0, having corrugated sides 0 and perforated bottom 0, and provided with vertical stationary radial paddles or partitions 01 upon its bottom. The dasher sits upon a carriage or round plate, 6, provided with lugs c, which enter the bottom of the dasher, and the carriage is fixed to a shaft, f, which passes down through the tub I) and supports the dasher. This carriage c c and shaft f were described by me in an application for a patent filed April 14, 1880.

Hot water, into which steam-is often injected, is let into the tubs, which are stationary, and passes through the perforated bottom 0 into the dasher, filling it to a point below the top ofits corrugated sides. The clothes are placed in the dasher, and reciprocating rotary motion is applied to the shaft f (by mechanism below described) and thence to the dasher, which, by means of its paddles d and corrugated sides 0, dashes the water about in a lively manner and thoroughly cleanses them.

(No model.)

In order to prevent the smaller articles of clothing from entering the space between the dasher and tub, a bonnet, g, is placed upon the tub I), of the shape shown, and extends inwardly over the top of the dasher, covering the space between it and thetub.

Motion is applied to the shaft f, connecting with each dasher, as follows: A driving-wheel, h, is driven by a belt, and has on each side a crank, k, fixed to the shaft h. Connected with each crank is a rod, 1, pivoted in a horizontal bar, m, sliding in supports m. A rod, n, is pivoted to the bar m and the rod 19, which latter is fixed to the shat'tf. (See Fig. 2.) The driving-wheel it, through the crank 70 and connecting-rod Z, imparts reciprocating motion to the bar on, which, by means of the rods n p, imparts reciprocating rotary motion to the shaftj' and dasher c.

In the drawings mechanism exactly in duplicate extends to each tubto the first tub on one side, and to the second on the opposite side, of the frame-from the driving-shaft h. Both tubs could be connected with the same bar m, and as many tubs may be added as desired.

This machine being intended mainly for use in large laundries, steam-power is usually applied.

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

l. The combination of the stationary tub I) with the rotary reciprocating dasher 0, provided with acorrugated wall and a perforated bottom, substantially as and for the purpose described.

2. The combination of the tub b with the rotary reciprocating dasher 0, having a corrugated inner wall. perforated bottom, and perforated cross-bars or partitions d, set at right angles to said bottom, substantially as and for the purpose specified.

JAMES Gr. CRAWFORD.
