LOUIS BALDAUF, OF MEQUON, VISOONSIN.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 335,735, dated February 9, 1886.

Application filed June 6, 1884. Serial No. 134,059. (No model.)

To all whom t may concern:

Be it known that I, LoUrs BALDAUF, of Mequon, in the county of Ozaukee, and in the State of NVisconsin, have invented certain new and useful Improvements in Washing Machines, and Ido hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to washing-machines; and it consists in certain peculiarities of construction, as will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my improved device, and Fig. 2 is a front elevation ofthe same with the side nearest the crank removed, but showing all theinside attachments in the place they would occupy on said side when in use. Fig. 3 is a longitudinal vertical section, showing the ar rangement of the interior bearings on one side ofthe wash-box, and Fig. 4 is a similar view showing the arrangement of the interior bearings on the other side.

A is the rounded bottom of my machine, made continuous, so as to form likewise the ends c and c; and B B represent the sides,the whole forming the wash-box, which for convenience is mounted upon suitable legs, a'l a2, and has handles B4 Bi, preferably formed sol idly with the sides B B.

Suitable bearings or boxes, b b, are secured upon the inside of thesidesB and B, the boxes Z1 being arranged near the upper part of said sides, at one end, and the boxes b being` disposed near the lower part of said sides, at the opposite end. These boxes receive the journals ofthe rollers or revolving shafts O C', around which passes the endless apron D, bearing exterior slats or strips, d, placed transversely thereon and secured thereto at slight distances apart. Secured to about the center of the inner side of each ofthe sides B B are vertical pieces Z)2 b2, forming a vertical passage or way, B2, between them, and in these ways the journals of an idler or loose roller, C2, have vertical play, the journal ofthis idler next the side B resting on a short strip, b, between the pieces b2 b2, while the other end of the loose roller C2 has no similar support for its journal; but the said loose roller presses down and rests directly ou the apron D. Another idler or loose rollenC, is sustained within the folds of the apron D at its lowest part, the side edges of the lower boxes, b', bearing against the jour nals ofthe idler C, thereby limiting its forward motion. Just forward of the strips b2bL are other vertical pieces, b"i b, secured in like ,manner to the twin surfaces ofthe sides BB', and

forming vertical ways B3 between them. On the side B these pieces b3?)3 haveashort piece, b, between them, all three pieces b3 b* bi being flush at their lower edges,and above'this short piece rests the metallic U-shaped bearing b, which receives one journal of the ribbed or corrugated rubbing-cylinder E. This cylinder is preferably a wooden shell covered with zinc, in eorrugations or in independent little cylinders placed close together, all around its periphery, and the other journal of this cylinder rests between the strips b3 bi, which are secured to the other side piece, B; but on that side there is no strip b* nor U-shaped bearing if, and hencey this end of the corrugated cylinder presses down and rests directly on the apron D, in similar manner to the loose roller or idler Ol already described.

On that head of the cylinder E which is next the side B there is rigidly secured the pinion E, having long teeth or eogs ee,which are adapted to mesh with the similarly-long teeth or cogs f f of the large operatingspinion F, secured on the shaft G, which latter' is mounted in suitable boxes or bearings, gg', on the sides B B of the wash-box, the said shaft G1 extending entirely across the machine, and in the same vertical plane as the `journals of the cylinder E. This shaft G is fitted with a 'c1-ank, H, having handle h at one end, outside of the box g, and at the other end, outside of the box g, with a pulley, I, while a sleeve, G', preferably of wood, envelops the said shaft between the box g and the large pinion F. K is a lever pivoted at k to the side B of the box, just inside and below the top edge thereof, and the upper side of the free end of this lever has a series of notches, k k', cut therein, in which may be adjustably supported the weight K', while between its weighted and pivoted ends this lever bears upon the top of a movable strip or piece, L, the lower end of which bears upon that journal of the cylinder high, (by any eXtra thickness of clothing,) so,

E next the side B, the said strip L being supported between the strips b3 b3 on that side of the washbox, and adapted to have vertical play in the way B3 between said strips.

One journal of the roller or revolving shaft C, already described, extends through the side B of the wash-box, and its outer end receives the large pulley M, which is connected by a suitable belt, m, with the small pulley I on the end of the shaft G.

The operation of my device will be readily understood from the foregoing description of its construction. The box is partially lled with warm soapy water or suds,7 and the soiled clothing is placed on the upper surface ofthe apron D. rlhen the crank H is turned, which communicates motion through the pinions F and vE to the rubbing-cylinder E, (to which, as stated, the pinion E is rigidly attached,) and also communicates motion to the apron D, through the pulley I on the end of the shaft G, the beltm, and the' pulley M on the end of the journal of the revolving shaft or roller C, over which the said apron turns. The clothing passes between the upper surface of the apron at its lowest point and the adjacent surface of the rubbingcylinder E, the idler C2 serving to compress the clothing` and keep it down fiat,

so as to pass between the apron and cylinder. The teeth of the pinions F and E are made long, as stated, and the object of their eXtra length is to provide for the vertical play or rising ofthe cylinder E on account of the thickness ofthe clothing passing under it, Without allowing the said pinions to get out of mesh. Vhen there are any particularly dirty spots on the clothing, it will not be necessary to again pass the same under the cylinder; but by'either slipping one end of the belt m off one of its pulleys M or I, or by simply holding the said belt with the left hand, the movement of the apron is thereby stopped, and the cylinder E can be either revolved or reciprocate over the soiled spots for whatever length of time may be necessary. The strips bG and b* preventone end of the idler C2 and the cylinder E from dropping down on the apron D to interfere with its revolution,while thepressure of these parts at their other ends insures that they shall bear sufficiently on the clothing, and to prevent this end of the cylinder E from being raised too that'there may not be suflicient pressure for proper cleansing of said clothing, the strip L is provided, on which any desired pressure may be applied by the weighted lever K, and this pressure may be adjusted or changed from time to time by shifting the weight K from one to the other of the notches 7c.

The interior of the wash-box is preferably lined with zinc or galvanized metal, so that there is nothing about my device to rust or injure the clothing washed therein.

It is not necessary that the shaft G should extend all the way across the machine, as instead two short shafts may extend into asolid roller, G, instead of a long shaft running through a sleeve; but in either case the sleeve or roller Gserves to protect the clothing from accidental contact with the metal shaft,and also serves to limit the upwardmovement of the lever K.

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

l. In a washing-machine, the combination of the wash-box with the rollers C C', idlers C2 G3, apron D, corrugated rubbing-cylinder E, shaft G, crank H, pinions E F, pulleys I M, and beltm, substantially as' set forth.

2. In a washing-machine, the combination, with the wash-box having guidestrips b3 b3, apron D, rollers C C', and rubbing-cylinder E, having pinion E,with long cogs e, of the shaft G, having pinion F, with long cogswhereby the said pinions are kept in mesh when the cylinder E and apron D are forced apart by eXtra thicknesses of clothing, substantially as set forth.

3. In a washing-machine, the combination, with the wash-box having guide-strips b3 b3, apron D, rollers C C, and rubbing-cylinder E, having pinion E', with long cogs c, of the shaft G, having pinion F, with long eogs f, strip L, pivoted lever K,with notches cld, and weight K', substantially as shown and described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.

LOUIS BALDAUF.
