Specification of Letters Patent. Patented Dag, 2'2, 191i);

Application filed June 19, 1909. Serial No. 503,108.

I the clothes wringer so that when the articles Fig. 5 is a detail view of the have been washed 1n the machine they may be passed at once through the wringer.

The invention consists of that certain novel construction and arrangement of arts to be hereinafter particularly pointe out and claimed.

In the drawings Figure 1 is a side elevation of the up er portion of a washing machine with wrlngerattached, embodying my improvement, as used in driving the washing machine. Fig. 2 is a similar view as connected with the wringer. Fig. 3 is a central verticalsection of a portion of the washing machine shaft, and its connections.

Fig. 4 1s a central vertical section of the in termediate gear for driving the wringer. ocking bar for the driving pinion of the washing machine.

1 is the 11 per portion of a washing ma chine, provi ed wlth a hinged lid 2 whichis secured by hinges 3, 3, to the edge of the receptacle, and mounted on one side of the washer is the wringer frame 4, carrying the usual wringer rolls driven by intermeshing gear, the upper portion of one of the gears 5 being shown inFigs. 1 and 2, The portion of the top of the washing machine which supports the wringer is fixed, and only the balance of the lid 2 is hinged.

Mounted onthe plate 6 secured on the upper surface of the hinged lid 2, is a water motor 7, which may be of the rotary or reciprocating type, or of, any other old and well known construction, the water under pressure being fed to the motor through one of the pipes 8, and the exhaust water from the motor taken off through the exhaust pipe 9. 10 is the piston rod of this motor, which is formed wlth a rack 11 on its outer end, and which engages with the pinion 12,

secured on the shaft 13 of the washing machine, so that the motor will drive this shaft in the usual way-for oscillating or rotating the paddles or rubbers of the washing machine. This rod or shaft 13 ofthe washer carries the rubbing device 14 at its lower end, and is providedwith a handle 15 at its upper end. The pinion 12 is provided with a square hole to receive the squared rod 13,

but rotate or oscillate with it. This pinion is provided with an elongated sleeve 16, which is journaled in the sleeve 17, secured to or a part of the bed plate 6 which carries the motor. The lower or inner end of the rod 13 is also rovided with a collar or sleeve 18 fixed t ereon, and the rod 13 is allowed a limited play in the sleeve 16 of the pinion within the limits of the slot 19 its bearing 17 by theset screw 20.

6. on the bolt 22 are the flanged and abutting

sleeves

23, 24. Loosely mounted on these sleeves is the gear wheel 25, while on the hub 26 of this gear are loosely mounted one on each side, the

arms

27, 28. These arms and the gear 25 are held in a central osition on the

sleeves

23, 24 by the coiled springs 29, 30, which bear between the flanges of the sleeves and the hubs of the arms.

The inner periphery of the gear 25, is rovided with ratchet teeth 31, and each 0 the

arms

27, 28 carries a pawl 32, 33, pivoted on the outer end of the arm, so that these pawls will engage the ratchet teeth of the gear. The inner ends of these pawls are connected by the

rods

34, 35 with a cross head or cross bar 36 secured to thepiston rod 10. It will be evident from this construction that as the piston rod is moving away from the motor, the pawl 33 will engage the ratchet teeth and as the piston rod is moving toward the motor the pawl 32 will engage the ratchet teeth, and the reciprocating motion of the piston rod will be converted into a constant rotary motion in one direction of the gear 25. The gear 25 is such a size and so located, that when the lid 2 of the washing machine is raised into vertical position and rest-s against the stop block 37 mounted on the receptacle 1, the gear 25 will be brought into mesh with the gear 38, mounted on the outer end of the lower shaft of the wringer, so that in this position the motor will drive the wringer.

When the lid 2 is closed the driving gear 25 so that the pinion will slide on the shaft,

in the sleeve 16, the sleeve 16 being held in Mounted on the boss 21 on the bed plate H is sixhply disconnected from the wringer ear.

b In order that when the wringer is being operated and the lid is raised, the washing machine apparatus may not be actuated, l provide the construction above described in which'the driving pinion 12 will permit the handle 15, secured on the washing machine shaft 13, to slide in the pinion until the collar 18 is brou ht into contact with thesleeve 16 of the pinion, and then the pinion itself will be raised within the limits of the slot 19, and disconnect the pinion from the rack 11 on the piston rod.

In order that in the use of the washing machine the rod 13 may not be raised accidentally by the clothes in the machine, so as to disconnect the inion, I rovide the locking bar 40 pivot on a stu 41 on the plate 6, which is arranged to be swung over the face of the pinion 12, as shown in Fig. 5 to prevent any accidental disconnection.

The operation of my device will be clear from the foregoing descri tion. When the clothes are to be washed, t elid 2 is lowered and the pinion 12- engages the rack 11, and the device 0 crates in the usual way under the action 0 the water motor. When it is desired to wring out the clothes, the operator simply raises the handle 15. The first ac tion is that the washing machine apparatus is drawn up close to the lid 2, so as to be out of the way. Further draft on the handle 15 disconnects the pinion 12 from the rack 11, and the gear 25 is brought into mesh with the gear 38 to drive the wringer.

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

1. In a driving mechanism, the combination of a base, a motor support hinged thereto, an element to be operated mounted thereon, a standard supported on said base, and another element to-be operated mounted on said standard, a motor mounted on said support, connecting mechanism between said motorandsaid first named element when said support is in one position, and connect ing mechanism between said motor and said second named element when said support is in another position, with means for shifting the motor support and connection therefor .to disconnect the first named element from its connecting mechanism when the support is shifted to its second position.

2. In a driving mechanism, the combination of a base, a motor support hinged thereto, an element to be operated mounted thereon, astandard supported on said base, and

train of gearing intermediate said motorand said second named element when the support is in another position, and means for shifting the motor support and connection therefor to disconnect the first named element from its train of gearing when the support is shifted to its second position.

3. In a driving mechanism, the combination of a base, a standardsupported on said base, and an element to be operated mounted thereon, a motor support hinged to the base, a shaft and pinion to be operated mounted on said support, and a motor mounted thereon, with gearing intermediate the motor and shaft for operating same in one position of the support, and gearing intermediate said motor and said base supported element for operating the same when the support is in another position, with means for shifting the motor support and connection therefor to disconnect said pinion from said gearing when the motor support is shifted to its last named position.

4. A driving mechanism comprising a base, a motorsupport hinged thereto, a.

shaft mounted on and passing through the support and having an external handle, a pinion slidingly mounted on said shaft, a motor and connecting mechanism mounted on said support to operate the pinion, and a sleeve on the shaft to disconnect the pinion when the motor support is moved into another position.

5. A driving mechanism comprising a base, a motor support hinged thereto, a shaft mounted on and passing through the support and having an external handle, a

"pinion slidingly mounted on said shaft, a

motor and connecting mechanism mounted on said support to operate'the pinion, and a sleeve on the shaft to disconnect the pinion when the motor support is moved into another position, a standard for another element to be operated, supported on said base, and connecting mechanism between said motor and said element when said support is in such other position.
