WRINGER.

Application led February 1.1, 1918. Serial No. 216,482.

To all whom 'it may concern:

Be it known that I, Bnirr A. STOCKING, a citizen oi the United States, and residing at Boone, in the county of Boone and State of Iowa, have invented a certain new and useful-Improvement in Wringers, of which the following is a specification.

This invention relates to washing `machines and more particularly to a machine of this character havingv a wringer attached thereto, and in which both the washing mechanism and the wringer may be driven or separately by hand as desired.

Among the objects of this invention is the provision of a washing machine and wringer so combined that they may be simultaneously driven from the same motor shaft, or upon the simple manipulation of suitable control elo-ments both the washing machine and the wringer may be separately operated by hand; to provide such form of connection between the wringer and shaft which drives the washing mechanism that the wringerrolls may be driven forward, backward, or thrown into position for operation by hand power; to provide means for automatically throwing the drain board into'proper inclination for -forward or backward rotation of the rolls: to provide novel means for regulating the pressure between the wringer rolls; to so arrange the mounting ofthe wringer upon the Washi ng machine platform that the wringer may be swung into and secured in any one of a plurality of positions with relation to the tub, without disturbing its operative connection with the motor Shaft in the least; to locate the driving motorA entirely above the tub and other working parts so that it will notl be liable to injury through moisture from the'tub, and will be convenientlyv located and easily accessible -to the operator; to provide a pulley wheel on the drive shaft vso that the washing mechanism and wringer may be operated either by a motor located directly on the drive shaft, or by a belt from a separate source of motive power; to provide a novel form of means for holding the tub in tilted position while draining the water therefrom; to provide an improved form 'of stop er for the tub drain outlet; further to all' 3rdp an improved `form and arrangement of means for selectively throwing the washing mechashown in Fig. l with the supplemental tub and platform being broken away-and partly in section.

Fig. 3 is a side elevation of the machine shown in Fig. 1, with parts in crossv section for the sake of' clearness.

Fig. 4 is an end elevation with the supplemental tub and platform removed and showing the wringer in position for. service to ing the wringer swung to a position at right l of the tub in cross section for the sake of clearness.

Fig. 5 -is a vertical transverse section through the column which carries the upright shaft.

Fig. 6 is a' vertical transverse section through the wringer.

angles with its position in Fig. 1; and parts i, 80

Fig. 9 is a detail view of the means for i i locking the wringer in any one of a plurality of adjusted positions.

Referring to the drawings: 1 designates the stand which is provi-ded with suitable legs 2, uponthebottom of which are mounted the casters 3. Detachably. connected with the stand 1 by means of hooks 4 which take into apertures 5 along the edge of the stand 1 is the supplemental table 6, which is supported in horizontal position at its outer edge by suitable legs 7. Upon this su plef menta-l table 6 is placed a supplemental) tub 6', to be used in the obvious manner in conjunction with the washing machine tub 10. -i Secured` to the opposite edge of the stand Suitably mounted upon one side of the tub' 1 are the hinge ears 8 with which are pivotally connected brackets 9, which are in turn secured to the bottom edge of the tub 10. At one end of the stand 1 is the aperture 11, and adjacent this aperture and pivotally connected to the tub 10 is the bar 12, the pointed corner 13 of which when the tub is in tilted position enters the aperture 11 and firmly holds the tub in such position. It is obvious, of course, that a. plurality of apertures 11 may be provided if de-v sired, which would increase the number of positions to which the tub may be tilted and held. Upon the top of the hubis the usual lid'14. through which extends the shaft 15. upon the lower end of which is mounted for rotation therewith the usual dasher 16. To the upper end of the shaft 15 is suitably attached mechanism for rotating theI same and comprising, located within the cover 17, a gear 18, see Fig. 1, which is rotated by means of a rack bar 19 attached to the upper end of the rocker arm 2O by means of a suitable pivot 21. Upon the upper end of the rocker arm 2O is also provideda handle socket 22 for use when it is desired to operate the washing mechanism by hand.

by means of screws, bolts, or the like. is a plate 23, which carries the bracket 24. and to which bracket is pivotally connected at its mid point the rocker arm 20. To each side of the plate 23 are suitably secured` as shown 4in Fig. 2, the respective ends of the hoop a, and upon whichv ends are suitable screw threads and nuts as shown for tightening said hoop around the tub.

Pivotally connected to the lower end of the rocker arm 20. is the connecting,t rod 25. the opposite end of which is .pivotally connected with the end of the crank arm 26. which crank arm is mounted upon the end of. the shaft 27. which Vis supported at the end adjacent the crank arm 26 by means of abracket 28 secured to the under side of the stand. Rigidlv secured to the opposite end of the shaft 27 is the gear 29. which .in turn meshes with the worm gear 30. carried by the lower end of the upright shaft 31.\ The gear 29 is provided with the hub portlon 32, one face 0f which has a clutch 2groove therein for engagement with a projection on the sleeve rigidly mounted upon the shaft 27. It will thus be seen that this groove and projection form a clutch by means of which rotation is transmitted from the gear 29 to the shaft 27. Also formed upon the hub and upon that side of the gear .29 opposite to the clutch just described is an annular groove 34, slidably engaging with which is a bifurcated end of the arm 35, which arm is rigidly secured upon the rod 36 -for movement therewith. Surrounding the gearing. mechanism just described is the casing 37, which is adapted 8 and 5, which' furnishes a-lsu-itable support for the' worm gearl 30. vThe rod 36 is `,mounted atone end in the sides ofthe casing 37 which surrounds the `gearing` just dcscribed. and is supported at its opposite end in the bracket B8 secured to the under side of the stand 1. Rigidly mounted upon the end of the shaft 36 and adjacent the bracket 38 is the handle 39. upon which is formed the projection 4t) for engagement with4 the notches 4l. in the quadrant 42. b v means of which notches the handle `may be secured in any one of a plurality of positionsI as desired. From the mechanism just described, it will be seen that the gear 22) may be moved laterall)v upon suitable movement of the handle 39, which lateral movement of the gear will throw the clutch formed upon its hub 32 either into or out of engagement with its corresponding part on the shaft 27. which will/result in the operation or not as desired of the washing mechanism, as will be apparent upon an inspection of the drawing.

Rig'idly secured up'on the lower end of the upright shaft 31 is the belt pulley 43. by means of which the shaft 31 may be rotated from -a separate motor or other source of motive power if desired. Mounted upon the stand l is the upright column 44.through which column extends the upright shaft 3l. The upper portion of the column 34- is counter bored as seen in each of Figs. 5 and 9. within which counter boreis located the sleeve 45. upon the upper end of which is secured the bracket 46. which bracket. car-l ries the wringer 47. Formed upon the upper end of the column 44 and adjacent. the sleeve 45 is the extension 48. see Fig. l). in which 'extension is pivotally mounted the lever 4.9.,by means of the pivot 50. Projecting' from each side of the lever 49 and slightly above the. -pivot 50 are the. arms 5l and 52. the arm 51 of which projects through the aperture and the inner arm 52 of which projects through the aperture 54, and fits into the socket. 55 formed in the lower portion of the sleeve 45. Snrroundintz the arm 51 is al compression coil spring 50 whose normal tendency is to force the arm 52 into locking engagement with one of the. sockets 55. A plurality of these sockets may be .dis-posed, around the circumference of theV sleeve 45 for a purpose tol be hereinafter disclosed.

As will be seen from an inspection ofllt) 56 and 57 of the bracket 46 is the sleeve 58, which is provided upon one end with the right hand threads 59, and upon its other end .with the left hand threads 60, between which threads is formed the depression 61. Mounted at the upper end of the shaft 31 is .a suitable motor 62 to impart rotation as thereto, and the pinion 69 fixed upon thek end of the rod 70, which rod is rotatably mounted in the wringer Aframe and carries upon its outer end the handle 71, which handle is pivotally mounted thereto, in order that the same may be swung in or out for seating into the slots 72 of the quadrant 73,

mounted upon the end of the wringer.l

Within said quadrant and between the wringer frame and the handle 71 is the spring 74, whose function is to resiliently hold said handle seated within thedesired notch of the quadrant in an obvious manner.

Formed integrallyT with one side of the car` riage 67 are the bifurcated arms 75 and 76` which arms lit on each sideI o-f the shaft 31 and o-ver the ends of the worm sleeve 58, see Figs. 1, 4 and 7, by virtue of which it will be apparent that as thev carriage 67 is moved up or down the sleeve 58 will have a similar motion imparted thereto. Secured upon the end of the shaft of t-he roll 63 is the gear '77 which is of suitable diameter to engagev with the worm teeth 59 or 60 on the worm sleeve 58 according as either of these worm teeth are thrown opposite'the gear 77.

Fastened t-o the top ofthe sliding carriage 67l is the rod 78, as shown in Figs. 2 and 3, which rod extends outwardly and downwardly 'and at its lower end is bent laterally to engage with the projection 79 on the lower portion of the drain board 80, which is tiltably mounted b een the uprights and 66 of the wringe me, and located just below thm-,roll 64, th function of which drain board fcarry away-fin an appropria 1- iection e excess water as it runs fre' he rolls. Th ifoll 64 is resilient-ly mounted upon the springs 81 and 82, see Fig. 6. which .Leach end this roll, [ear respectively upon 4` the under faces of which are provided with the bevelled por `tions 85 and 86 respectively. -The blocks 83 and 84 are mounted within the uprights of the wringer frame so as .to have a free up and down motion thereln except as limited by the springs 81 and 82 upon their upper portions, .and by the bevelled faces 87 and 88 of the blocks 89 and 90 respectively on their lower faces. As shown in Fig. 6, the blocks 89 and 90 are engaged by means of right andv left hand screw threads with the shaft 91, which carries upon its outer end Aa hand Wheel 92. By virtue of this right and left hand thread arrangement and the bevelled faces as shown, it will be apparent that uponl suitable rotation of the hand wheel 92, the blocks 89 and 90 will be moved inopposite directions, which will, because j of the sliding contact with the bevelled faces, result in the upper blocks 83 and 84 being either raised or lowered according to which direction the hand wheel 92 is turned.-

This will result in the springs 81 and 82 being either compressed or relieved of compression according to the direction offrotation of the hand wheel which in turn will make possible the desired adjustment of tension between the rolls 6? and 64.

Fastened by means of screws, rivets, or the like, to the blocks 89 and 90, see Fig. 8, is the handle 93, which extends parallel with the rolls to the end thereof and thence upwardly above the top of the wringer frame. When the handle 93 is thrown back away from the wringer frame, the blocks 89 and 90 which, as above stated, are secured to the lower port-ion of this handle, willl be abruptly rotated upon the shaft 91, and consequently quickly separated from contact with the bevelled fac/es and 86, which will result in the blocks 88 and 84 moving down-v wardly under act-ion of the springs 81 and 82, which will thus relieve the tension in said springs', and permit-ting the rolls 63 and and 64 to be separated. This will be of special value should /an article ofclothing become tangled withl the rolls during the wringing, or other accident take place.v As seen in Fig. 6, the shaft 94 of the lower roll 64 extends outwardly through the slot 95 of the upright 65, which shaft has a squared portion or other suitable configuration formed upon its outer end for the accommodation of a handle for use when it is desired to operate thewringer by hand.

Inserted through the bottom of the tub 1() is the drain pipe 96, which has screw threaded or other suitable engagement therewith. pipe by means of pivots 97, see Fig. 9, is the angular link 98, the outer portionof which directly opposite the drain pipe is provided with the aperture 99, see. Fig. 4, through which aperture extends the stem 100,y upon the end of which is fo-rmed a valve 101, which valveis adapted'to fit in the valve se-at'102. The ste-m 100 may have screw.

Pivoted to each -side of the .drain similar construction if desired. Upon the outer end of the stem 100 is the handle 103, by means of which the valve l0() may be readily placed against the seat 102 or removed therefrom. This con/struction results in an easily and quickly operated and e):- eeedngly efiicient stopper' for use when it is desired to drain all of the water from the interior of the tub.

rIhe operation of my improved deviceis as follows: Upon suitable movement of the handle 39 the gear 29 will be thrown into engagement with the worin wheel 30, the upright shaft 3l` having been previously set in motion by starting the motor 62, which will cause said gear 29 to rotate, and thus impart rotation to the crank arm 26, which in turn will operate the rocker arm 20 and rack bar 19, and thus in an obvious manner impart`motionto the dasher mechanism within the tub. At the same time that the washerl mechanism 4is being operated, the wringer may also be simultaneously operated, and this is effected by manipulation in suitable direction of the handlel 71 mounted upon the wringer` which movement of the handle will either raise or lower the sliding carriage 67, thus carrying with it the arms 75 and 7G, which as seen in Fig. l correspondingly move the sleeve. 58 upwardly or downwardly on the shaft 31, the particular direction being determined by the direction of the movement of the handle 71. For the sake of illustration, we will assume that the sleeve 58 has been moved upwardly which will, as seen in'Fig. 2, place the worm teeth 59 in engagement with the gear 77, which will impart motion to the wringer rolls in the appropriate direction. It is also to be noticed that during the movement of the carriage 67 upwardly, the rod 78 shown in Fig. 3 will be carried upwardly therewith, which will result, due to the connection heretofore described of this rod with the drain board, in the tilting ot' the drain board 80 to the proper. inclination with respect to the rolls to carry oft the water from the rolls in the proper direction. Should it be desired to reverse the direction of the rotation of the rolls, this can be readily accomplished by moving the handle 71 to the other extreme of the quadrant, which will lower the sliding carriage G7,`and in turn the slee-ve 58, thus throwingthe worm teeth 60 into engagement with the gear 77. Since the teeth 59 are right hand and the teeth C0 left hand, it will be obvious that this last stated operation will reverse the direction of rotation of the rolls, and due to the connection hereinbefore set forth of the rod 7 8 with both the drain board 8O yand the sliding carriage 67, the inclination of the Vdrain board will automatically be changed simultaneously with the shifting of the gears and changing of rotation of the rolls. It is, of

it may be there locked by -inserting the projection 52 into the nearest socket atrthe new position. Attention is called to the fact that the wringer rolls may be operated equally well and also simultaneously with the washing mechanisnr no matter what position the wringer occupies, and that this motion may also take place during the time that the wringer is being swung from one position to another, since the driving connection of the wringer and the Washing' mechanism is entirely independent from the mechanism by which the adjustment of the wringer is effected. As already pointed` out, if it is desired to drain the water from the tub, this may be easily accomplished by tilting the tub and placing the free end of the bar 12 in engagement with the aperture 11. which will hold the tub in such tilted position.

I consider the mounting of the motor at the top of the shaft as an important feature. danger of moisture from the tub, and is much more accessible to the operator than if placed beneath the stand. p

In order to permit of movement of the bevelled blocks 89 and 90 towards or away from each other, the lower laterally extending portion 93 of the handle 93 is provided with the elongated slot 93, within which slide the neck portions of the screws 93h.
