Whereansnzi: a similar nietio ennge1x1e11t will he Y6 and ihe train alternately in nypesi'ie (he LiliVClL through the worm wheel 66 and worm (S5. The clutch member 78 and clutch lever 82 are so bad anced and arranged as to be retained in either operative or inope 'ative positions. After moving the clutch lever upwardly as described, the worm It will operate to drive the intermediate shaft 86, whereupon the crank arm 89 will be. rotated and a recipro eating angular movement will be imparted to the geared sector 93. As the geared sector moves alternately in opposite directions, the pinion 4S and load shaft. 30 will be rotated continuously and be automatically reversed in the direction of rotation when the geared sector reaches either limit of its travel.

When it is desired to connect the transmitting shaft. 67 for driving the shaft of a wringer supported upon the upper part of the washing machine, the operating lever 119 may be manipulated. as previously described. to cause the wringer driving shaft 110 to be rotated in the desired direction. When the wringer shaft is being driven the clutch member 78 may, if desired. be rendered inoperative. thus discontinuing the rotation of the cylinder 20.

From the foregoing description it will be apparent that a number of the gears of the driving mechanism are contained within the housing 73, and that the gears of the wringer driving clutch mechanism are con t ained within the housing 100. These gears are thus protected from dirt and moisture. and at the same time access may be readily gained to the interior of these housings by removing the cover 120 and cover portion 73. It will fnrtherbe apparent that the pinion t8 and rack teeth 95 are protected by the transverse outwardly extending flange of the plate -10 of the member 35.

It ,will be seen that all of the parts of my improved driving mechanism are carried by the. frame 35 of novel form and arrangement of parts. During the operation of the driv ing mechanism the coil spring 58 operates contimiously to maintain a tight. frictional contact. between the belt 53 and the pulley wheel 52. and the motor-driving wheel with which it eoacts.

Although I have shown and described a particular embodiment. of the invention. it will be understood that l contemplate changes in form and arramgaanent of parts as circumstances may suggest. or necessity require, .withont departing from the scope of the invention as defined in the appended claims.
