Original application filed December 9, `1320, Serial No. 429,438. vIlivded. and this application filed March 2,2, 1921. Serial No. 454,367.

To @ZZ whom t 'may conce/rn.'

Be it known that l, Josemi CnossLnY, a citizen ci the United States, residing at rlfrenton, in the county of Mercer and State of New Jersey,have invented certain new and useful Improvements y'in Driving Mechanism, of which the following is a specilication.

This invention relates to driving` mechanism tor use in connection with washing machines, and is adaptable particularly to the washing machine :illustrated and described in my copondingl application Vfor Letters Patent, Seria-l Number 429,478, tiled Decem.- ber 9, 1920, of which ,the present application is a division. n

The primary or Igeneral object of' the invention isto provide gea-ring of an improved nature for developing the energy ot a motor or other power source into rotary movement and transmitting such movement to the clothes containing cylinder of the washing machine,

A further object of the invention is to provide mechanism for the purpose stated which operates automatically at predetermined cyof the parts is at alltimes assured, with the possibility ot breakage, wear or derangement of any of the parts being remote.

A still further object of the invention includes the improved manually i controlled clutch mechanism, which in a facile manner, enables the operator ot the machine to instantly and accurately control the movements and operation of the latter.

`With these objects in view, together'. with others which will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement ot parts, all vas will be described more fully hereinafter, illustrated in the drawings, and particularly pointed `out in the claims.

vshowing the mechanism changed to such position as will cause'the cylinder to rotate in reverse direction, i

nig. 5 is a sectional view tially upon line 5--5 of Fig. 3,

F 6 is a vertical sectional view. taken on line 6 6 of Fig. 5,' and F 7 is a horizontal sectional view taken on line 7-7 of Fig". 3. i i

its the improved gearing'disclosed herein lis primarily for use in connection with washing machines it will be described as adapted to that use, but it l'will be understood that such association is not to be considered. as a limitation ot the invention to siich use, as the invention is applicable to a varietyot machines or mechanisms where alternating rotary driving movements'are required. i f

i wall of the wash tub is indicated generally at and to' this wall and upon the interior ot the tub a motor 3() issecure'd. "This motor is enclosed by a water tight casing, and the shaft 31 oi the motor, which itend's trans\'iersely into the tub,fis provided with a suitable packing gland to vpreclude, the entrance oi? water to the interior of the motor case.` lhe motor, as will be understood, will be energized by being wired with a sui" Jblc source et electrical energ f, and the operaton ot the `motor is controlled by the push button switch indicated at 35 arranged in the hase ot' the motor.

rllhe power gearingior the washing inachine isconlined within a casing disposed within the tub and secured to one end wall thereoin adjacent to the. motor 30 and below theplane of the latter. The' outer end of this vcasing terminates in an annulus 37 which has arranged therein a. worm vgear 38. Thisfworm gear is engaged by'a worm-39 drivenby the sha't 3l oi the motor. ln theA present instance, the worm is disposed beneath a cup 40 to receive a suitable lubricant,

taken substanby a housing 59, the inner end of-which is of lequal diameter with and Yengages 'theH edges of annulus 37.v Screws or bolts may be employed for securing this housing to the casing, and it will be understood that a water tightconnection between the casing and housing must be established. The housing has arranged centrally therein a shaft 60, the said shaft being alined with the central opening 61 in the worm gear 3S. The shaft is hollow and receives a slidable clutch carrying rod 62 extending throughout the length of the said shaft. rlhe inner end ofthis rod carries a clutch member 63 adapted to engage with the clutch face Get carried by worm gear 38, and when the rod is retracted this clutch member is withdrawn from the said clutch face and is conlined within the head 65 at the extreme inner end of shaft 60. As shown particularly in Figs. 1 and 2 of the drawing, the gear 38 has a central opening to receive the head 55. The rear face of the gear 38 has secured thereto a plate, as indicated in Fig. l, and this plate is provided with the clutch face Gil to receive the clutch member 63 carried by the rod 62. When the rod is moved to its limit in one direction, the clutch member 63k will protrude from head 65 and engage with 'the clutch face 64- of the plate, whereby a positive drive connection is established between gear 38 and the head 65, while retraction of the clutch member 623 vfrom face 64 breaks this power connection and the said member is then wholly housed by the head 65. rllhe outer end of the rod 62 is provided with a grooved head 66 which is engaged a pin carried by arm G7 connected to operatii'ig rod 68. ll his rod is mounted in suitable bearings in housing 59 and protrudes at one end to the exterior of the housing. The protruding end ot the rod is equipped with a handle ($9 to enable the same to be readily operated.

The hollow shaft 60 is provided inwardly from its ends with a worm 70 engaged by worm wheel 71 carried by the worin shaft 7:2 disposed transversely of the housing. This worm shaft has also secured thereon a cani wheel 73., havingcam surfaces ill-"5 at its -able bearings within the housing and dis-r posed transversely thereof, and has a recess Z9 in one face thereof to receive a lug S0 projecting laterally from the upper edge of the rocker plate Sil. T his rocker plate is supported at its lower end by a bushing S2 extending forwardly from the same and litting within bearing S3 in the forward face of the housing. The bushing 82 receives and rotatably supports the rotatable cylinder operating shaft Se, the forward end of which is squared as at 85 to engage with the cylinder socket, while the inner end of the said shaft has a spur gear 86 allixedtherem to. The rocker plate 81 has trunnions 8T, 88 and 89 projecting therefrom, and upon which are rotatable pinions 90, 91 and 92; the trunnions 8?*89 being so disposed that the pinions w-92 carried there-by are at all times in mesh with the gear 86, while trunnion Sl's so disposed that the pinion 91 carried thereby is in mesh with ypinion 92. The pinions 90-91 are adapted to be brought alternately into mesh with gear 93 secured to shaft 60. rll`his movement of the gears is caused by operation of the rocker plate 81 through instrumentality of cam wheel 73, as will be understood. lt is apparent that Iby the arrangement of pinions Q1- 92, the

ried by the worm gear 38. The mechanism within the housing at once becomes active, and the hollow shaft 60 at once begins to ro tate, and the cylinder operating shaft will rotate in one direction or the other, depending upon which of the gears 99 or 91 is engaged with the gear 93.' As the hollow shaft rGO rota-tes. the worm wheel 70 is turned, as

is cam wheel 73. As the cam wheel continues to turn, one of the cani faces thereof will move out of engagement with its cooperating roller "Z6, while the cam face upon the opposite side of the wheel will contact with its cooperating roller, and through the instrumentality of the pin 77 supporting said roller, will force the gear shifting bar to move; said movement causing roclrerplate 8l to correspondingly ymove. This movenient of the rocker plate disengages from gear 93 the pinion which has heretofore been in mesh therewith, and causes the said gear ifi-tacos it will be understood that two or more of such faces may be provided if desired, and it will be understood further that the periodic number of rotations in opposite directions of shaft Set may be controlled by increasing or decreasing'the length` of the said cam faces on the opposing faces of wheel 73.

The clothes containing cylinder or basket is indicated diagrammatically at 95, and it will be understood that this cylinder may be of any preferred type or style and may be rotatably mounted in any desired manner in the tub.

From the foregoing, it is obviousl that I have provided mechanism fully capable of carrying forth the objects mentioned above for which it is particularly adapted, and although the above is a description of the invent-ion in its` preferred embodiment, it will be understood that the invention is lnot to be limited to the precise structure or use set forth, as variations in adaptability and detailed arrangement may beresorted to if desired without departing from the invention as defined by the claims.
