useful Improvements in Gearing; and l do hereby declare the following to be a full,

clear, and enactdcscription of the invention,

such 'will enable others skilled in the art to which it appertains to malte and usethe saine. y v

This invention relatos to' a reversing mechanism for Washing machines and has tor an object to provide a motor driven mechanism with improved means for applying the power thereto.

.fi further-object of the invention is to provide improved means for reversing the rotation of the drum at the end of a predetermined number ot revolutions.

W ith these and other objects in view the invention comprises certain novel constructions combinations and arrangement of parts as willV be hereinafter more fully described and claimed.

in the drawings z-li`igure l is a view of the Washing machine in perspective, two of the gear casings being broken away to show the construction of thegearing. Fig'. 2 is anenlsrged detail vievv of the drum oper# ating Fig. 3 is a view in eleva'- tion of the back ci the drum operating gear with part of the reversing mechanism carried thereby. l is a view in edge eleva-- tion4 oi? a part of the reversing' mechanism as indicated at arrow 6 in Fig. 5. Fig. 5 a reverse View in elevation of the step by step portion of the reversing mechanism.

Lilie characters of reference indicate corresponding parts throughout the 'several views The' improved gearing forming the subject mat-ter of this invention. is, adapted to be applied to any machine requiring an automatic reversal of its rotating. parts, but Aas here shown it is applied to-a Washing machine 1.0 which is provided with a stud shaft 2l by means of which any suitable foraminous drum 16 is rotated.

vMounted' in any convenient l,rmsition vrelative tothe body, is a motor 27 of any approved or convenient type, here shown as a Aconventional electric motor ,controlled from a convenient-ly disposed switch! albevel gear-30 and drives an inclined shaft V31 .will oe apparent 'that when the lever 36 is -naled upon the rear' side of the gear'; as' y,

of motor is. wholly immaterial to the present invention and any convenient type of motor may be employed. The motor 27 is connected with a shaft 29 which extends to a to` which extends' into the gear casing 32 secured upon one end of the body 10. The gear casing 32 contains a bevel gear 33 connected to the stub shaft 2l and the inclined shaft 31- is provided with a bevel pinion 34 intergeared with the gear 33 by which the foraminous drum 16 is rotated from the mot-or 27. The shaft 31 also carries a second pinion 35 with a clutch 36 isplined upon the shaft 3l and adapted to vengage either of said pinions 34 or 35 to rotate the foraminous drum in either direction, such clutch being manually controlled by means 'of a lever 36. Upon-the exterior of thel 'gear casing 32 a block 37 is located having notches 38 formed therein and the lever 36 is provided ivith aspring-pressed detent for engaging such notches. When the lever is located With 'the detent 39 in the center of the notches 38 as indicated at Figs. l' and 2, the clutch 36 is out. of engagement with both of the pinions 34 and 'sothat the orarninous-drum 16 remains stationary. Itr

moved in one direction one of the pinions will beV engaged and when moved inthe opposite direction the opposite pinion will be. engaged, thereby reversing the direction of rotation of such oraminous drum.

In the operation of the drum it is de- 90- sirable to rotate the drum a number of timesY in one direction and then to reverseA the rotation and. rotate it a like number of times.

in the opposite direction. To automatically accomplish this purpose the lever 36 is provided With diverging spring arms 401and' the gear 33 is provided With a pin 41 vwhich at times extends beyond the surface of the gear and into position to engage one of the' spring arms 40 toautomatically move the lever 36. To cause the pin 4l to move upwardly into position to engage onei'of the Y arms 40 automatically a cam disk 42 1s jour indicated at Figs. 3 and Il,l suchdisk havrigng a cam? 43 positioned when properly'rotated to engage the rounded head 44 ofthe pin" 41 to force it outwardly ntoposition to enga-ge such spring arms. The cam disk` though it is to be understood that the. type {l2/.is .rotated with a step by movement 110 by means of a pin 45 carried by the gear casing and the rounded head 44 is positioned to engage in cencavit'ies 46 at each partial movement of the disk 42ltovmaintain such `disk Vinw'theV proper position sopthat the notches 47 in the edge ofsucliwdiskwvvill ben properly located to engage the pin 45 at the next rotation of the gear 33. As illustrated,

there aresix of the concavities 46 which, together with the step represented by the cam 43, insure the rotation of the disk 42 once -for each seven rotations of the gear 33 and foraminous drum 16. At the completion of the seventh revolution the pin 45` will be moved outwardly to engage one of the spring arms and will automatically ber, of a driven shaft extending at right an-4 gles to the axis of rotation of the rotatable member, a gear rigidly connected -Wit-h the y rotatable member, pmions carried by the shaft spaced to engage opposite sides of the gear, a clutch splinedl upon the shaft adapted toengage seleetively'eithenof the pin- .ions, a lever positioned to actuate the clutch, 4spring arms carriedjby and extending upon opposite sides of the: lever, a; pin carried by the gear adapted to 'engage'- thespring arms, and means carried by the gear for..

lifting the pin at-the end ofa predetermined cycle of revolution.

3. The combination with a rotatable member, of'a gear rigidly connected with said rotatabell member and coinciding With its axis of rotation, of a driven shaft extending diametrically across the gear, pinions loosely mounted upon the shaft and spaced to engage the opposite sides of the gear, a clutch splined upon the shaft and adapted to selectively engage either of said gears, a lever adapted to actuate the clutch, a pin extending through the gear and positioned to move the lever, a cam Wheel carried upon the rear of the gear, a rigid member adapted to engage the cam Wheel and rotate said cam wheel with a step by step movement, and a cam carried by the cam Wheel adapted to .raise the pin into position to engage with the lever. l
