- f PMM ,WASHiNG-'I'VIACHINE SPECIFICATION forming part of Letters Patent No. 444,010, dated January 6, 1891.

Application filed Dctober 23,

To @ZZ whom, it may concern.-

Be it known that I, WILLIAM J. NoRwooD, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Vashing-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.

My invention relates to certain new and useful improvements in washing-machines,and is designed to provide an apparatus whereby laundry may be effectually and quickly washed, rinsed, and dried without subjecting it to the mechanical wearing action of pounders, scrubber-boards, or squeezing-rollers.

In the accompanying drawings, illustrative of my invention, Figure 1 represents a top plan View of my improved washing-machine with the top of the casing removed, and Fig. 2 represents a vertical central section thereof.

Similar numerals of reference indicate similar parts in both figures.

Referring to the drawings, 3 indicates a stout metallic frame-work or casting, constituting the base or standard upon which the working parts are mounted. To the top plate or table 4, secured to the frame-work 3, is secured by rivets, as shown, or otherwise, the

- receptacle 5, provided at its bottom with the drawing-0E pipe 6, and at a convenient distance above the latter with the inlet-pipe 7, adapted to be connected with a suitable water-supply pipe. In a suitable step 8 is mounted the vertical shaft 9, having a fixed pulley l0 or the like to be driven from any convenient source of power.

The vertical shaft 9 passes through a stuffing-box 11 and upward through an aperture in the top plate 4. Above said top plate it is made hollow, as shown, and is provided with apertures 12, communicating` with the hollow interior. Flaring or bell-mouthed pipes 13 14 also communicate with said hollow interior at its lower portion, and above said pipes is located the nap-valve 15, or its equivalent, which will permit the fiow of liquid through the hollow shaft in an upward direction, but which will prevent it from flowing downward past said valve.

Upon the vertical shaft 9 is fixed the bottom piece 16, and upon said bottom piece are located the concentric cylinders 17 18, provided with perforations 19 20, as shown, from top to bottom, so as to permit the ready passage of liquid through them. A spider consisting of a central portion 2l and arms 22 is mounted upon the upper part of the shaft 9 and furnishes a top support or steadiment for the concentric cylinders 17 1S, and a nut 23 holds the spider in place.

Thepartsof myinvention being constructed and arranged as described,its mode of operation is as follows: The laundry to be cleansed is inserted within'the space included between the concentric cylinders 1 7 18, and water having soap in solution is admit ted into the receptacle 5, either through the pipe 7 or by pouring it in at the top of the receptacle 5. The shaft 9 is now set. in rotation by means of the band-pulley 10, whereupon the water in the receptacle 5 is drawn up through the tubes 13 14 into the hollow portion of the shaft 9 and passes the fiat valve 15 and issues through the openings in the hollow shaft into the chamber 17, and thence by centrifugal force passes through the openings 19 and through the laundry, and thence out through the openings 2O to the receptacle 5. In this manner, by continuous rotation of the shaft 9, a continuous circulation of soapsuds passes constantly through the laundry, effectually cleaning it. The soap-suds are then drawn off from the receptacle 5 by means of the outlet-cock 6, and clean water is admitted through the inlet-pipe 7. Rotation of the shaft 9 is then recommenced and the fresh water is forced through the laundry as before, thereby rinsing it. The rinsing-water is in turn withdrawn by means of the outlet-cock 6, and the shaft again rotated at a much higher speed, thereby throwing off by centrifugal force all the remaining water contained in the laundry until it is entirely dry and readyfor removal. D uring this latter operation it is preferable to allow the outlet-cock 6 to remain open, so that the water thrown off from the laundry may iiow out from the receptacle 5 instead of being taken up by the pipes 12 13.

1. A washingmachine consisting of an outer receptacle, a central hollow shaft hav- IOO ing` openings at its bottom communicating with the outer .receptacle and a, perforated upper portion, and 'concentric cylinders perforated from top to bottom and mounted upon said shaft, substantially as described.

2. A washingmachine consisting of an outer receptacle, a central holloit7 shaft having openings at its bottom and a perforated upper portion, oppositely-bent pipes connected to the bottom openings, and concentric cylinders perforated from top to bottom and mounted upon said shaft, substantially as described.

3. A washing machine consisting of an outer receptacle, a central hollow shaft provided at its lower portion with an upwardlyopening valve and with bottom openings below said valve and having a perforated upper portion, and concentric cylinders perforated from top to bottom and mounted upon said shaft, substantially as described.

4. A Washing machine consisting of an outer receptacle, a central hollow shaft provided at its lowerportion' with an upwardlyo'p'eh'ig 'Vai'feah'd with bottom 'openings below said 'valve an'dhai'i'ng a perforated upper portion, oppositely-bent pipes connected to the bottom openings, and concentric cylinders perforated from top to bottom and mounted vupo'nsaid shaft,s'ubstantiaily as described.

5. A washing# machine consisting of an outer receptacle, a central hollow shaft hav ing openings at its bottom communicating with the outer receptacle and a perforated upper portion, and concentric perforated cylinders mounted upon said shaft, the inner cylinder being closed at top and bottom, so as to promote or assist the circulation, substantially as described.

ln testimony whereof I affix n'iysignature in presence of two witnesses.
