To aZZ whom it may concern."

Be it known that I, CHARLrs Mn'rnnwrrz, a subject of the Czar of Russia, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification.

My invention relates to improvements in washing machines and mode particularly to machines of this class having receptacles of an oscillatory or rocking type.

My improved machine is particularly adapted to handle household washing and to facilitate the several operations of washing, rinsing, and wringing by incorporating mechanisms for performing these operations in a sin le compact machine.

The c jects of the invention are to produce a comparatively simple, durable and reliable machine which may be driven either by hand or by power. To so arrange the several mechanisms for performing the operations of washing, rinsing and wringing thatthe clothes or other material being operated upon may be conveniently moved from the washing receptacle to the rinsing receptacle and then to and through the wringer, and to so locate and position the parts of the machine'that the movable ele ments may be readily exposed for inspection, repair or replacement. These and other objects I accomplish as hereinafter described in the foilowing description and as particulariy pointed out in the appended claims, reference beingzhad to the accompanying drawings in which an embodiment of the invention is shown.

.11 the drawings Figure 1, is a side elevation of my improved washing machine, the hinged doors on that side of the machine being bro ren away to expose the interior construction. Fig. E2, is a side elevation of my improved washing machine, looking at the side oppositethe side shown in Fig. 1, and the hinged doors on that side being also broken away to expose the interior construction. Fig. 3, is a top view of the improved washing machine. ig. 4, is a vertical longitudinal section through the washing machine taken on line 4-4, Fig. 3. Fig. 5, is a detached horizontal section through the hoilow washing receptacle taken on line 55 4. and looking downward in the direction of the arrows in said Fig. 4-. Fig. 6, is a fragmentary longitudinal vertical section through the washing machine to illustrate the oscillatory toothed rack for rockcompanying drawings in detail, like numerals designate corresponding parts.

While my improved machine is. principally designed for household use, it may if desired be used in laundries, hotels and other places where it is necessary to wash comparatively large quantities of clothes or other material each day.

As shown, the frame of the machine is upright and longitudinally elongated and consistsof two parallel vertical side members 1 and 2, which are held in separated arrangement by a series of transverse connections.

Referring to Fig. 4:, it will be noted that 53 two troughs are arranged in the upper portion of the frame one being located at one end and forming a catch trough 3 for the water from the washing receptacle which is mounted vertically over it, and the other which is smaller than the catch trough 3, being arranged near the center of the frame and constituting a rinsing basin 4, into which the clothes are dropped as they are removed from the washing receptacle. Both of the troughs 3 and 4 are provided with drain taps 5 and 6, and a shallow tray 7 is slidably mounted in the frame beneath the taps. The

tray is also provided with a drain tap 7".

The side frame members 1, and 2, have vertical extensions 8, projecting upward from hear one end and awashing receptacle 9 is mounted between said extensions so as to oscillate therein. I prefer to make the washing receptacle in a hollow oval form as shown in Fig. 4 in cross sectiom'and provide it with a series of inwardly extending ribs 10, arranged at intervals on the interior of the receptacle over which the clothes bump as the receptacle is rocked. A removable cover 11, is fitted in thetop of the receptacle through whichclothes are introduoed into or removed from the same. The

extensions 8, are connected at their upper extremitiesby a horizontal cross bar 12, and a rocking lever 13 is pivotally ,hung from said cross bar. This lever is providedwith an enlarged loop like intermediate portion 14, which'is transversely elongated and is provided on its lower inner edge with a cross rack -15 of teeth which mesh with a pinion 16, mounted on one of the short shafts 17 extending from the ends naled in the extensions 8, as shown in Fig. 6. The side frame members are recessed on their exterior to provide hollow spaces 18, and these spaces are normally closed by hinged doors l9. Owing to this construction, hollow spaces of narrow width are provided' on each side of the frame in which portions. of the power transmitting mechanism are located, as will be more clearly hereinafter described. I

The machine, may be either operated by power or hand'and in Fi 4 an electric in Fig. 1, which is fitted on a shaft 42, fournaled in the end of the frame. This shaft 42, carries a grooved wheel 43, which is con nected by a belt 44, with the ooved wheel '27 on the shaft 28. At the on of the frame opposite theshaft 42, is detachably mounted,

a wringer. which is constructed substans J tially as shown in Figs. 1, 4 and 7 having an upright rectangular frame 45 and a large a main upper roller 46 and two small lower of the washing receptacle which are jourmotor 20' is shown, the shaft 21 bf which carries a worm 22, which meshes with a gear wheel, 23 on a transverse shaft 24'. The

shaft 24 is connected by belt 25, and grooved wheels 26 and 27 to a second transverse shaft 28, which in eurn is connected by gear wheels 29 and 30 to a third shaft 31. The two first mentioned shafts 24 and 28 are comparatively short, while-the third shaft is long and extends transversely through the machine to the opposite side thereof where a grooved wheel 32' is mounted upon its projecting end. The lowerend of'the lever 13, is 'operatively .connected' to the wheel 32 by a "connecting rod 3'3fl sc'that rotation of ment by manually Referring to Fig. 5, the, 1nterior of washing receptacle may "if diisired bggdithe wheel 32 will rock the lever. To provide means for adjusting the point of attachment of the connecting rod 33, to the lever a series of holes 34 are formed in any one of Wlllph the pivot 35 may be inserted, and toffacilitate disconnecting the rod from the receptacle, thelever may be formed with an extra pivoted arm 36, which is pivoted 'at its upper end tothe lever and normally held, immovably to the lever by a slip band 37. When.;.it is desired to, stop the washing receptacle from rocking without down which permits the arm 36 to oscillate without moving the lever 13. The washing receptacle is protected and inclosed by hinged screens 38 which can be' opened when itisidesired to introduce or remove clothes into or from the washing receptacle.

' The lever 13, is yieldingly balanced between two opposed springs 39, which are connected stopping the machine, the band 37 is slipped to bpposite sides of the loop portion 14, and hangif'rorn oppositely extending wires 40, as

shown in Fig. 2 Besides the'electric motor the machine may be operated by hand by turning a handle 41, shown in dotted lines lents.

rollers 47 and 4-8, arranged horizontally side by side and mounted in said'frame. The 1 main roller-is yieldingly pressed down upon the smaller lower rollers by zig-zag bent springs 49, and thumb screws 50 are arranged in the top of the. frame for the pur-.

pose of adjusting the tension of the springs. i

A grooved wheel 51 is mounted on .a'short shaft 52,- which is connected by a. belt .53 to the grooved wheel 32, and transmits power to th wringer throu ha clutch. The preferable form of cl-utc .is shown in Fig. 9

and consists of two clutch members 54 and 55, a shifting lever 56, and a transverse arm 57 at' the upper end of said lever which is a spring 59 and is provided. with notches 60 into which the part 58jis adapted to snap. The clutch is shiftedintowr out of engagedepressing and then laterally movingthe arm 57. I

The operation'of my, improved machine will be easily understood from the foregoing description.

. The rollers ofthe wringer are connected together by, meshing gear wheels 61, 62 and erefore do not wish to be limited to thecbnstruction herein shown and described, but desire-to avail myself of all such variations, alterations, modifications and changes as fairly fall within the scope of the appended claims or may be construed to come within the same by involving the doctrine of equiv-a- What I claim as my invention and desire to secure by Letters Patent is 1. In a machine of the class described in combination, a frame, a washing receptacle mounted in said frame so as to rock on a horizontal axis, a standard on said frame projecting above the level. of said amis, an oscillatory lever pivoted on the upper part 90 held in contact with a locking vpart 58, by

of said standard of said standard and extending downwardly therefrom, said lever having a loop-like portion provided with a toothed rack and the washing receptacle having a pinion meshing with said rack, arms extending outwardly and downwardly from said standard, and springs connecting said arms with the ends of the loop portion.

2. In a machine of the class described in combination, a frame, a washing receptacle mounted in said frame so as to rock on a horizontal axis, a standard on said frame projecting above the level of said axis, an oscillatory lever pivoted on the upper part and extending downwardly therefrom, said lever having a loop like portion provided with a toothed rack,
