of which the following is a specication. I

This invention relates to washing machines of the "type in which the tubis rotatahlyA oscillated', and my object is to devise means for'applyin a motor drive lto such I be 'substantially noiseless, will operate with very little' friction and whichV will not bind if the tub and motor get out of alinement.

I attain my object by a construction which -v may be briefly described as follows:

On a suitable frame the tub is journaled and also a verticalshaft 'close beside the tub. An oscillating rotary motor is connected to the top of the shaft and a pulley to the lower end thereof. A pulley, preferably 4segmental, is securedto the tub' below thebottom thereof. Two chains, preferably crossed, are each secured at one end to one pulley and at the other end to the other pulley wherebypthe movements are transmittedI to the tub. a

Figure l is a side elevation of a `washing machine constructed in accordance with my invention. Fig. 2 is a plan view.

In the drawings like letters of reference indicate corresponding parts in the different figures. l

A is the tub stand which carries the spindle B on which the tub C is mounted for oscillatable rotation.

D isa. fra-me comprising a pair of standards suitable cross connections, which will usuallyv be employed for the attachment of a wringer. This frame is suitably braced from the stand Lby the braces a and b. To this frame 1s secured a bracket E, preferably formed of amalleable casting, adapted to furnish bearings forvthe vertical spindle F. A water-motor G, of the well-known oscillatable rotary'type, has part secured to the upper end ofthe spindle F,=while its casing is secured bv means of the bolts o to the uiper. end K of the bracket E. The location o the motor at the upper end of this spindle is important as suitable drainage must be provided.

Owing to the fact that the construction in such a washing machine is of wood and comparatively light, andy also owing to the ment only sshown.

of the motor' fact that the tubs'ymay warp out of shape,

it is cliflicult to provide satisfactory gearing between' the motor and the Atub which will not bind and cause' excessive. friction.` The construction I will now describe satisfactorily vovercomes all objections.

To the lower end of the spindle F is connected a2pulley H and to the underside of the tub is suitably secured the' pulley I. As the tub ordinarily moves onlyv through an are of about ldegrees oli-either side of its normal position, this pulley I may be a seg- The constant change in the direction of movement-'of the tub renders any belt connection between 'the-two pulleys inadmissible,vand ordinary sprocket chains under the conditions obtaining are too noisy and involve excessive friction, to say nothing of 'the danger of catchingand tearing the clothes of the operator. I overcome, these difficulties by employing as the transmission means flexible bands `or substantially flat chains J secured respectively at one end to the pulley H and at the other end to the pulley I. As it is desirable to cross' the chains to keep themxwell underneath the tub where they are away from the pulleys,`the chains are preferably secured to the pulleys H and I so that they can occupy differenthorizontal planes and in order to maintain this'separat-ion each pulley is provided with a'rib (Z. The constant change of motion at .the end ofthe arc of oscillation in either direction involves a considerable shock to the driving mechanism. To ease this shock I prefer to provide a cushion connection between one end of each chain and one of the pulleys, preferably the pulley I. This connection will best be seen on reference to Fig. 2. i

Itrvvill be seen that at each end of the segmental pulley I a lugo is formed through which passes an eye-bolt f. Each eye-bolt is provided with a Wing nut g, and on the stem of the eye-bolt between the lug e .and

Wingnut is llocated a spring cushion 71 preferably a block of rubber. i

It will be seen that the top Knef the bracket E is formed as a tray which projects over the top of the tub sothat the drip from the motor is caught and dischar ed into the tub, the rim z' of the tray being cut away over the tub to provide angoutlet.

The transmission hereinhefore described will be found to satisfactorily transmit the tot.v cpnvnecied 'to s v4Would' b'e a lfailure,v While/the Lwhole com# mou"E tedIl thereonl`- for! -gosllatable rotatien 4rtieil,fr a'r'n'ejlorseeilrom the stand be'- fa.
