WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 563,373, dated July 7, 1896.

Application led April 19, 1894. Serial No. 508,182. (No model.)

To @ZZ whom it may concern.'

Be it known that I, LARs GRONDAHL, a citizen of the United States,residingat Red Wing, in the county of Goodhue, State of Minnesota, have invented certain new and useful Improvements in Vashing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention is designed to produce a neat and compact machine adapted to operate on large and also on small washings without undue wear on the clothes during the operation of washing.

The clothes-receiving tank being adapted to receive therein, and resting on its bottom, a tank of smaller size, is provided in front thereof, and integral With said outer tank, with a receptacle having a metallic bottom in which the clothes can be soaped before they are automatically operated upon by pounders.

In the accompanying drawings, Figure lis a perspective view of a washing-machine constructed in accordance with my invention, the front being shown open. Fig. 2 is a transverse vertical section of the same on line @c a; of Fig. 3. Fig. 3 is a horizontal section on line y y of Fig. 2, but with the front shutter' or tank-cover removed. Fig. 4 is a perspective view of the supplementary tank of small size.

In said drawings, A represents the'sides of a receptacle having its rear end A2 extended higher than its front end A6. Said receptacle is provided with an inclined bottom A4, eX- tended from its front end about half-way to its rear end. In the rear of said bottom is placed the tank B, pendent therefrom. The bottom of said tank is semicylindrical to per mit the clothes placed therein to be easily revolved by the action of the pounders O, that are mounted vertically above it. The front portion b of the sheet metal, of which the tank B is made, is extended nearly horizontally and rests upon the inclined bottom A4, and thus a convenient receptacle and platform is obtained upon which the clothes can be soaped and the suds made to return into the tank B.

ing the tank B is supported at a suitable height above the floor by four'legs A6, secured to the sides A. Y

To the rear portion of the sides A are vertically secured two boards A6,`in which bearings @2 are placed or formed for the multiplecrank shaft E. The boards A6 are also secured to the high rear end boards A2 of the frame, and the upper ends of said boards are united together by the top board D. Each pounder is guided vertically by means of a rectangular stem C2, secured to its rear face and made to pass through grooves made in cleats a6, secured to the front face of the rear board A2 of the frame. The crank-shaft E is provided at one end with a crank-handle c and at the opposite end with a Iiy-wheel E2, that may be .used as a belt-wheel.

Each crank of the shaft E is united to a pounder by means of a connecting-rod O3, having one end received in a cavity of said pounder and pivoted thereto at c. The front face of each pounder is provided with horizontal serrations or inverted steps, which are to press upon and to rub the clothes placed with suds in the tank B, and partly revolve them under each pounding, the concave bottom of said tank facilitating said rotation.

To prevent splashing of the suds from the tank, and also to retain the warm vapors of said suds as much as possible in contact with the clothes, said tank and also the pounders and their connecting-rods and crank-shaft are covered over by means of folding shutters hinged to the top board D and to each other. For this purpose a board F is hinged at f to the front edge of said top board. A front shutter F2 is hinged at f2 to the board F, and a bottom shutter F"s is hinged at f6 to the lower edge of the shutter F2. The shutter F2 is secured to one of the vertical sides A6 by means of a hooked spring-dog g, attached to the inner side of said shutter, said dog being adapted to engage with an angular keeper h, secured to the inner face of the side A6 of the frame. The shutter F3 is secured in position to inclose the beaters C by means of a hook lo, secured to the outer face of the side A6 and adapted to come in engagement with a screw-eye-.m'on one end of said shutter F2'.

One of the advantages obtained from the front receptacle having the sheet metal b is that when a wringer is attached to one of the IOO sides A the water dripping from said wringer will fall back into said receptacle. To reduce the size of the tank or to permit clothes of different textures to be operated upon separately by two of the pounders, a secondary tank B2 is placed within the tank B. Said tank B2 is of such size and form as to have its front and rear sides and bottom fitting closely Within the tank B, but is of shorter length, said length being only half, as shown in the drawings. To prevent any accidental displacement of the tank B2, its ends b2 have their front portion made to extend up to the level of the bottom b of the front receptacle and a narrow strip of Wood f4, secured to the inner face of the shutter F3, is made to bear thereon.

Having now fully described my invention, I claim- In a Washing-machine the combination of verticallyoperated pounders, A a stationary tank B having a semieylindrical bottom under said pounders and in front of said tank a receptacle having vertical sides A, an inclined bottom, and upon said bottom a covering sheet of metal Z7 constituting a part of the stationary tank, and a secondary tank B2 within the tank B with hinged shutters F2 and F3 the latter being provided With a wood strip f4 to retain the tank B2 within the tank B substantially as described.

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

LARS GRONDAHL.
