Application filed October 23, 1911. Serial No. 656,158.

.To all whom it may concern:

Be it known that I, GUSTAVE WENZEL- MANN, a citizen of the United States, and residing at Galesburg, in the county of Knox and State of Illinois, have invented a new and useful Improvement in Operating Means for Driven Mechanisms, of which the complete specification.

' The main objects of this invention are to provide a washing machine stand with novel means for supporting various positions required without interfering with wringer operating mechanism; to provide an improved construction whereby a single wringer may be employed with a plurality of washers and tubs and be shifted to its various operative positions without detaching it from its mountings; to provide adevice in which the position ofthe wringer may be changed with but slight .eifort; to provide means for simultaneously driving the washers, or either one thereof while the other is at rest; to provide means for simultaneously operating a washer and the wringer, or both washers and the wringer; to provide a support for the wringer adapted tocompensate for unevenness in the floor; and to provide a strong, cheap, and durable construction adapted to-greatly lessen the labor ordinarily occasioned with such devices.

. Goncisely stated, the objects ofthe inven-- tionare to generally improvethe construction and increase the capacity, efliciency and utility of devices of this character.

A specific embodiment of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of-a washing machine,-washing machine stand, and horizontally. swinging wringer therefor embodied in this invention. a Fig. 2 is a top, plan view of the same with the wringershown in its various operative positions. Fig. 3 is a section taken on line 3-3 of Fig. 1, showing the wringer mounting and operating mechanism in side elevation. Fig. 4 is a frontielevation of the wringer mounting and operat ing mechanism. Fig. on line 5-5 of Fig. 1. Fig. 6 is a fragmentary plan view of the reversing m'echamsm for the wringer. Fig. 7 1s a fragmentary side elevation of said reversing mechanism.

In the construction shown the stand or bench 1 has mounted thereon two washers,

2 mid two. tubs s an.

the wringer in the j ournaled a bearing 24.

5 is a section'taken conveniently arranged in the form of a square. Journaled in suitable bearings beneath the top or platform of the bench is the transmission shaft 6 from which the washer and wringer mechanism are operated. A drive shaft 7 is also journaled in the bench, parallel wlth the transmission shaft, and is provided on its outer end with a drive pulley 8. On the inner end of the shaft 7 1s a pinion 9 which meshes with a gear 10 on the shaft 6 to drive the latter shaft.

Loosely mounted on the shaft 6, at a point intermediate the tubs and washers, are beveled pinions'll and 12, which areprovided on their adj acent faces with clutch members 13 and 14;,- respectively, as shown best in Fig. 3. A bearing standard 15 has a fork 16 at its lower end, in the arms of which the shaft 6 isjournaled. Said arms bear against the outer faces of said pinions and act to hold the pinions in position on the shaft 6. Said standard extends upwardly through the top of the bench to a point slightly above the level of the washers, and is provided with a laterally offset bearing 17 at its upper end in axial alinement with a bearing 18 in the fork 16. A theft 19 is in the bearings 17 md 18 and pro ects above the bearing 17, and is provided on its lower end with a beveled gear Wheel 29 inmesh with the pinions 11 and 12.

The upper end of the bearing 17 is provided with a peripheral groove 21, and a wringer supporting arm 22 is provided on its end adjacent to-the shaft 19 with a fork 23 adapted to engage in said groove. Mounted on the arm 22 above the fork 23 is The upper end 25 of the shaft 19 is angular in cross section, and a beveled pinion 26 is mounted on the top of the bearing 24 and is provided with a stud shaft or pin 27 which is journaled in and projects through the bearing 24, and is provided in its lower end with an angular socket in which the end 25 of the shaft 19 loosely fits. Rigidly secured on the under side of the'arm 22 is a brace 28 which projects downwardly and toward the shaft 19 and its end 29 is turned horizontally and provided with-an aperture through which the shaft 19 projects.

A bracket 30 is socured on the standard 15 in position to supwashers or thetubs.

The connection between "the arm 22 Land;

the standard 15 and shaft l9 permits the outer end of said arm to have sufficient vertical movement to compensate for any inequalities in the floor, and to facilitate sw nging. it to its various operative positlofis."

Mounted on the arm'22 is the wringer 31 having a shaft 32 which is journaled in abearing 33 on'the arm 22 and is provided on its outer end with a beveled pinion 34 inlmesh with the pinion 26.

Extending upwardly from the bench 1 are posts 35, 36 and 37, which are positioned respectively to support the outer end of thewringer arm 22whenlthe wringer is in position to wring from the washer 2 to the tub 4,.tub 4 to tub 5, and vice versa, and from the washer-"3 .to the tub 5. On the top of each post is a plate 38 havinga down-turned flange 39 at its outer edge which is provided witha notch 40, and carried in the outer end of the arm 22 is a bolt 41 having a hook 42at its lower end adapted to engage in the notch 40when the arm is resting on the top ofxthe post and hold t e wringer rigidly in place. The upper end of the bolt ispro- .vided. with awing-nut 43 adapted to draw thehookup into the notch.

For the purpose of reversing the wringer a clutch member 44 is ,slidably mounted on the shaft 6 intermediate the clutch members 13. and 14 and adapted to engage therewith to lock the pinions to the shaft 6. A bell-crank lever 45 is pivoted-on a pin or shaft 46 extending stand 1 and is provided with a fork 47 at one end'which engages in a groove in the clutch member 44, and the other end of said lever '45 is providedwith a'slot 48.

Journaled in the legs 49 of the stand is a rock shaft 50,-. and journaled in the legs 51 is a rock shaft 52" vided. with; an upwardly directed arm 53 which arms are pivotally connected together by'a bar-54. Extending upwardly from the engages in theslot 48; On each end ofg-the shafts 50 and 52 is a treadle 57 in position for the operator to operate with the foot when wringing from either of the i When the treadle is thrown; in one direction "the I bell-crank lever 45"shifts the lu'tch member 44 to engage the clutch'member'13 *and when thrown in the opposite direction the shifted to the clutch member 14' thereby reversingthe'drive'of the wringer. For the purpose 'of normally holding the clutch member Mouth of engagement with both the clutch members 13 and 14 coiled springs 58-are connected to the forked end of the levei 45 and to the stud pins 59 on the under side of the stand to i downwardlyfrom the top of the.

, Each rock shaft is prosired to wring from the tub 4 to the tub 5,- 100 For: the purpose of operating the washers the shaft 6 is provided with a clutch member 60 which is rigidly secured thereon, and With a cup shaped pitman 61 which is slidably secured 'on' said shaft and is provided witha clutch member 62 adaptedto engagethe clutch member 60. A bar 63-ispivoted' at its upper end toa bracket 64 supported beneath the top of the stand and is connect ed intermediate its'ends to the pitman 61-by means of a link 65. A lever 66 is pivoted to a stud'shaft 67 carried on the top. of the stand intermediate the washers 2 and'3. A- link Gdpivotally connects the lower end of the bar 63 with the-lower end of the lever 66. Arms 69 and 76 are pivoted to the up- 7 per end of the lever 66 and are provided attheir opposite ends with a hook 71 adapted to engage the rack 72 of the washer mechanism. The pitman 61 is adapted to slide on the'shaft 6 to throw the clutch member 62"- in'to and out of engagement with the clutch member 60. i g

The operation of the construction shown is as follows: When the'wringer is in the position shown in Fig. 1 and the pulley 8: is driven in the direction indicated by the arrow in Fig. 2, if the clutch member 44 is thrown 'into engagement with the clutch member 14, the wringer will be turned in a. direction to wring from the washer 2 into the tub 4. The wringer is held rigidly in place by means of the bolt 41 which engages the plate 38 on the post 35. When it'is ;de*

or yice versa, the wringer arm 22 is releasedlfrom the post 35 and sw. :Jg on the shaft 19-,as a center until its outer end rests on the post- 36'." In this position clothes 'may' be" wrung from either of the tubs '4 or 5 into the other by simply shifting 'the'clutch member upwardly directed pin 56 in its upper end 44. When it is desired to wring from the washer 3 to the tub 5jthe wringer arm is swung around to the post 37. In shifting the wringer to its various positions the driving mechanism therefor is in'." no way disconnected or interfered withs'ince the pinion 34 simply travels aroundfon the pinion 26. The yielding connection between v the arm 22 and the standard 15 and shaft 19- permits theouter end of the arm 22 to have suflicient vertical movement to enable it to be easily placed on or removed from the supporting'posts therefor.

The .treadles 57 are so situated that the in any ofthe positions in which the operator is. required to stand when wringo '70- from the operating mechanism of the one not in use. .While but one specific embodiment of the .w

*mventitm has been herein shownand operator may easily shift the clutch member-r clutch member 44 is 44 standard, a horizontally swinging arm at theltop thereof, a fork onithe arm, loosely engaging the top of the standard, a shaft journaled on the standard, a stud-shaft journaled on the arm-and loosely coupled to said shaft, a gear on the stud shaft, an operative mechanism mounted on the arm and driven by said gear, and means for supporting the outer end of said arm.

2. In a device of the character described, a stand, a standard thereon, a shaft journaled on the standard, means adapted to rotate the shaft in-either direction, an arm pivotally mounted on the standard and adapted to rotate aboutsaid shaft as a center, an operative mechanism mounted on the arm and adapted-to be driven from said shaft, posts on'the stand, adapted to support the outer end of the arm, and means for locking the outer end o'f the arm to the posts.

3. A device of the nature described comprising a stand, an operative mechanism, means adapted to support it above the stand and adapted to swing in horizontal are, a shaft journaled at the axis of movement of said mechanism and adapted to operate it, clutch mechanism and means associated therewith adapted to drive said shaft in either direction, and means for operating the clutch mechanism.

In testimony whereof I have hereunto subscribed my name in the presence of two witnesses. s
