UNITED STATES CHARLES A. BENTZEN,

WASHING- SPECIFICATION formingpart of Letters Application filed October 20, 1880.

To all whom it may concern: l

Be it known that 1, CHARLES A. BENTZEN, of the city of Chicago, county of Cook, and State of Illinois, have invented certain Improvements in Washing-Machines, of which the following is a specification.

My invention relates, `first, to providing the containing-box for the clothes with brushes or scratchers made of rice-roots, which I have discovered to be well adapted to rubbing and scratching the clothes when the latter are set in motion, because they do not readily become soft in Water, as bristles would do, nor become oxidized and discolor the clothes, as metal wires would do, nor are they so hard as to cut the clothes. t

My invention relates, secondly, to a device adapted to both rub and pound the clothes, consisting ot' a disk provided with downwardly project-ing rubbers, whose exteriors are iiuted so that they present sharp ridges to the clothes and rub and scratch them at the same time they are pounded, anddriven around to and fro in the containing-box by the motio'ns designed to b e given to the device.

In the accompanying drawings, Figure 1 represents a vertical section of a washing-machine embracing my improvement in its con'- struction, the section being taken as indicatedby broken line l 1 in Fig. 3; Fig. 2, a like section taken as indicated by the broken line 2 2 in Fig. 3; Fig. 3, a plan of the same; Fig. 4, a horizontal section of the said containing-box; Fig. 5, a bottom view ofthe said disk provided with the iluted rubbers, and Fig. 6 a'detail view of the lower end of one of the rubbers c.

A indicates the containing-box, having four sides and a bottom and a top orlid, B, hinged thereto, and to which the rubbing and pounding device is attached, so that the latter may be turned out of and into the box at will.

b. is a board resting on the bottom of the box, and it is provided, as shown, with small brushes r, which are made of rice-roots, and which maybe fastened thereupon in any suitable manner.

b, b2, b3, and b4 are like boards, in like manner provided with rice-root brushes, and they are placed against the four vertical Walls of the box, and are held together in position by PATENT OinrrcE^ OF CHICAGO, ILLINOIS.

l means of their rabbet-joints, so that they can be removed upward only, even when the top may be turned oft'.

` The rubbing and pounding device, consisting of the disk C, having the uted rubbers c, is adaptedrto have a rot-aryreciprocating motion and a vertical reciprocating motion given to it simultaneously by the mechanical device shown in the drawings; but no claim is made herein for that mechanical device, which is, however, described and claimed in my pending application for a United States patent for a mechanical device filed November23, 1880. The rubbers c -are fixed upon the under side of the disk C, are convexed on their lower ends, and their exposed surfaces are covered with sharp ridges, and therefore when they move back and forth horizontally they scratch and rub the clothes,

and down into the clothes, these sharp edges still scratch and rub the clothes at the same time that the whole device, consisting of the disk and the rubbers c, pound them, and the rice-root brushes co-operate in the scratching and rubbing whenever the clothes are put in motion by the scratching and pounding device.

I am aware that in the United States piatbearing date January 29, 1877, isshown a disk provided upon its lower surface with numerous downwardly-projecting knobs by which the clothes are agitated and rubbed, but such knobs are not provided with sharp ridges, as my rubbers c are, but are smooth. I am aware, also, that in the like patent issued to G. Burkhardt for a washing-machine, dated May 14, 1878, is shown a plunger provided on its under side with lugs or projections which rinse the clothes about77 when' the plunger is turned 5 but these lugs are very small and short, and are flat and smooth oIl their lower ends. I `am aware, also, that in a like patentissued to J. W. Parker for a washing-machine, dated December 13, 1861, is shown a device consisting of two bars crossing each other at right angles and attached together, and from the outer end of each bar extends downward a round rod, and upon each rod a fluted roller turns, and is held in place by a 'knob or nut.

and then, when the device moves up out of ent issued to J. Myers for a washing-machine,

IOO

The rollers are designed to turn freely on the rods, but are not designed or adapted to pounding the clothes, their lower ends being square and smooth. I am aware, also, that it is not new to provide the interior of the containingboX of a washing-machine with corrugations or ridges adapted to scratch the clothes. I do not therefore claim any of these constructions; but

What I do claim as my invention,and desire to secure by Letters Patent, is-

1. The rubbing, scratching, and pounding device consisting ot' the disk C, provided with the downward projecting rubbers c, having rounded lower ends, and their entire exposed surfaces covered with sharp ridges, the whole adapted not only to pound the clothes and force them back and forth around the interior ot the containing-box, but also to scratch and rub them in both the vertical and horizontal 2 motions of' the same, substantially as described.

2. The box A, having the lining-boards b, b', b2, b3, and b4, provided with rice-root brushes r, adapted to rub and scratch the clothes when 25 the clothes are thrown against them by the pounding and scratching device, substantially as described.
