To alt'whom itmag i concern .2

Be: it known t at 11, Joann Dmrza citizen of the United-States, and a resixlent of Ci'nvide operating mechanism for a washing machine adapted tobe driven by a motor mounted upon the machine, and means whereby a wninger may be operated when; desired by the same source of power which I actuates said operating -mechanism.

Another object of any invention is to .produce operating mechanism for a washing; machine which is adapted to be driven by, electrical or other :motive power, means} whereby a wringer may be started, driven in reverse-directions and stopped at the same time the washing machine is being driven, means for throwlng the washing-ma chine into and out of operation while the; wringer is being operated, endvmeans whereby the lid or support of the washing"ma-'; chine may be raised to open position with; out interfering with the -o crating mechaof the wringenrand without having tog turn off the source ofpower to raise saidi lid-or support.

My invention consists in providing incombination with a nmtono erating'mecha-f: IYlSIILCOIIEPI lSiRg a chain 0 gears, a crank? shaft driven therby, atelescopic she-ft also; driven thereby, gearing onsaid telescopic. shaft, and =a shaft driven said gearing.

My invention also consists mmeans whereby said crank shaft mud-said shaft may be thrown into and out of operative en-. grgement with said driving power, -eithersimultaneously or successively. v Q My invention also consists the -parts,& combination and subcombination parts; and in the :peculiar'and :particular constrnef tion,flocat ion and arrangement of :parts'= with relation to-the washing machine of the type herein illustrated, as set forth and claimed. V

Fig. 2 is an end elevation of the washing machine --equipped with my invention. Fig. 3 is a side elevation of a washing machine equippedwith my invention, the machine being shown in open position. Fig. 4 is-an enlarged detail view of the mechanism adapted to-drive the wringer.

Fig. 6 is a detail sectional elevation illustrating the 'wrlnger operating mechanism. Fig. 7 is an enlarged detail view of the male clutch member of the Wringer operating mechanism. Fig. 8 is a detail view illustrating one of the pinion gears employed in the driving mechanism for the wringer. Fig. 9 is a detail elevation ofthe bracket to which the 5 motor is attached, said bracket being mounted upon the lid or support of the washing machine. Fig. 10' is a detail: View of right angled shaft employed in connecting the 'wrmger operating mechanism to the mechanism adapted to'dri-ve the washin machine.

1:1 is an elevational view of the driving gear wheel, which is adapted. to mesh with,

supported on legs 2. The body or tub 1 is 3 provided with theusual rub boards 3 and 4,

the washing machine being of the double rub board or reciprocating rubber type.

The rub boards are pivoted in the usualmanner, the lower one 3 being pivoted in the tub 1, and the upper rub board being piv- ,ing machine of the ordinary construction,

ote'd in the lid or support 5 of the washing 1 5 machine.

Anarm '6 is fastened to the lower rub' board 3 and. extends to the crank arm 7 on the shaft 8 of the driving mechanism. Con- 17 and is the customary manner, and is a nected to said arm also is a pitman rod 9 which connects to a vertical extending arm 10 fastened to the upper rub board 4 on the washing machine. This construction is of the ordinary type of washing machines employingthe double rub board. Thus when the shaft 8 is driven, the crank arm 7 is driven, thereby imparting a reciprocating action to the upper rub board 4 of the washing machine, and also a reciprocating action to the lower rub board 3 of the washing machine. i v

The lid or support 5 is hinged at 11 in so provided with the usual door 12 at the top thereof. A chain 13 is provided to prevent the .lid from being opened too far, said chain being fastened at one end to the tub 1, and at the other end to the lid or support 5 of the washing machine. Thus it is seen that thev and mount same u on the lid or support 5 of the washing mac ine, said bracket being constructed to accommodate the necessary shafts and motor which will be described.

A motor 18 is mounted upon the bracket rovided with a inion gear 19, which is a apted to mesh with a large gear wheel 20. The large gear wheel 20 is best illustrated in Fig. 11 where it is seen that it is provided with a bevel pinion gear 21 at one side and a sprocket pinion 22 at the other side. Said gear wheel 20 is mounted upon the ri ht angled shaft 23. One end 24 0 said sha 23 is adapted to enter the boss 25 on the bracket 17 as best shown in Fig. 9.

" The right angled shaft is shown in detail in Fig. 10. The end 24 of the shaft 23 may be pivptally secured or held in the boss 25 in any desired manner preferably by. lock nut 24, said boss 25 acting as a bearing forsaid shaft also. The bracket 17 is also provided with upright supporting standards 26 and 27 in which is mounted a driving or crank shaft 8. The driving shaft 8 has a sprocket 29 mounted at one end, and a crank arm-7 at the other end. :The sprocket.

29 and sprocket pinion 22 are connected by means of a sprocket chain 30, and are thus driven together. The sprocket'29, however,

is mounted loosely upon the driving shaft 8, and is disposed upon said shaft directly above the sprocket pinion 22. Now to cause the sprocket 29 tooperate and thereby operate the shaft 8, it is necessary to rovide a clutch to be operated by hand w en it is desired to operate therubbers 3 and 4 of the washing machine. T

The clutch mechanism is asfollows: I provide a bracket 28 on the lid 5 of the washing machine adjacent the middle of the side of said lid. The said bracket 28 is provided with an upwardly extending portion 31, which is best shown in Figs. 5 and 13. The gearextension 31 is bifurcated, and forms a pivot 32 for the. main operating lever 33. To prevent the operating lever 33 from being moved too far, I provide another extension 34 on the bracket 28 which is rovided with a slot 44 therein, which is ad pted to receive a latch which will be described. Mounted on the end of the shaft 8 I provide a male clutch member 35, which is provided with an annular groove 36. The said clutch member 35 is slidably mounted on said shaft, preferably splined thereto, and allowed to slide longitudinally along said shaft. The sprocket 29 is provided with the female member37 of the clutch. A spring 38 bears against the sprocket 29 and the clutch member 35 andnormally holds said clutch member out of engagement with the clutch member 37 on the sprocket wheel 29. The end of the operating lever is bifurcated to form a yoke 33 which fits into the annular groove 36 on the male clutch member 35. The operating lever 33 is provided with a pivoted handle 39 which is pivoted at 40 to the main operating lever 33. It .is the purpose of this pivotedhandle 39 to act; as a latch, it being provided with an extension 41 at the end thereof, which is adapted to extend down through an opening 42 in the main operating lever 33Uand engage with the slot or notch 44 in the extension 34 on the bracket 28. A spring 43 is referably provided between the pivoted an'dle 39 and'the main operating lever 33. Thus .the extension 41 on the handle 39 is always held in engagement with the top edge of the ex-- tension 34 of the bracket 28. Thus when it is desired to cause the sprocket 29 to drive the shaft 8, thereby operating the rub boards of-the washing machlne, it is first necessary to throw the handle portion'of the operatingslever 33 outwardly, thereby throwing the clutch members 35 and 37 into engage ment with each-other, and causing the shaft 8 to operate, due to the fact that the clutch member 35 is always turning with said shaft 8, it being splined thereto.- The clutch members 35 and 37' will remain in engagement with each other until -thel j'pivoted handle 39 is forced downwardly, thereby releasing the-latch extension 41 from the slot 44 and allowing spring 38 to fonce the clutchme'mbers 35 and 37 apart, thereby allowing the sprocket 29 to run loosely on .the shaft "8 Wringer is a bell shaped beveled gear 45,

preferably pinned thereon, asbest shown in Fig. 6. I The shaft is made smaller at the end shown at 46, upon which is mounted a 15 shield disk L7, which is also provided with bearings 48. The shield 17 is loosely mount ed upon said shaft 15, shown in Fig. 6 and is adapted to allow said shaft15 to rotate therein. The shield 47 is provided with small housings 49 diametrically opposite each other. In these housings are disposed pinion gears 50, said pinion gears being mounted upon a shaft 51 which passes through the bearings 48 on the shield disk 47. A detail of the pinion gears 50 is shown in Fig. 8, where it is seen that each pinion gear 50 is provided-with a female clutch member 52 at one side thereof, and is pro vided with an annular groove 53 at the other side thereof. The pinion gears 50 are looselymounted upon said shaft 51 and are held in their properposition on said shaft by means of a set screw 54 passing through the housing 49 and entering a groove 53 in '35 said pinion gears 50. Thus the set screws 54: are adapted to hold said pinion gears in their proper position on the shaft 51. When properly placed, the pinion gears 50 mesh with the bell shaped bevel gear and are an adapted to drivesaid bell shaped gear when said pinion gears are driven with the shaft 51. I

It is seen that another clutch device must be employed to cause either one of said pin- 45 ion gears 50 to operate with the shaft 51 in order to drive the bell shaped bevel gear 45, and thereby drive the wringer rollers.

I, therefore, provide a slidable clutch sleeve 55, which is preferably splined by means of so spline 56, on the shaft 51,;as best shown in Fig. 6. The clutch sleeve 55 is allowed to slide longitudinally on the shaft 51, al-

though it is splined thereto, and is provided,

with male clutches 57 at each end thereof; 55 the clutch sleeve 55 is 'also'provided with an annular channel 58 which is adapted to receive the end of an arm 59. The arm 59 is pivoted at 60 ,and' is provided with a handle 61 on the other sidethereof. Thus so when thearm 59 is rocked upon its pivot 60, it immediately slides the clutch sleeve 55 longitudinally. on the shaft 51, and thereby throws one of the male clutches 5'7 into engagement with the female clutch on either as one of the pinion gears 50, which ever way the arm 59 happens'to be rocked. In this manner I am enabled to obtain an eflicient reversing clutch. mechanism for the wringer, inasmuch as I am enabled to operate either pinion gear 50 with the shaft 51, thereby causing the bell shaped bevel gear 45 to rotate in either direction.

The operating means for-shaft 51 will now be described: The right angled shaft 23 is provided with another extension 62, which is, provided with an annular groove 63 near the end. A hollow shaft 64 is adapted to cover the extension 62 of the right angled shaft 23, and is adapted to rotate thereon. A set screw 65 is provided in the hollow shaft 64, and is adapted to enter the annular groove 63 in the extension 62 of the shaft 23, and the hollow shaft 64 is thereby prevented from moving longitudinally relative to the extension 62. The shaft 51 is adapted to enter the hollow shaft- 64, and extend therein a considerable distance. The end of the hollow shaft 64 is provided with a spline 66, which is adapted to slide in an elongated spline way- 67 in the shaft 51. Thus it is seen that the shaft connection between the wringer mechanism and the operating mech- 'which is adapted to'mesh with said pinion gear 21. The pinion gear 68 is pinned or otherwise securely fastened to the hollow shaft v6 and is-adapted .to drive said hollow shaft 64, the hollow shaft 64 in turn being adapted to drive the shaft 51 by means of the spline 66.

The importance of providing a telescopic shaft arrangement as described, is readilyseen when the lid or support 5 of the washing machine is raised, as shown in Fig. This figure clearly illustrates why the slid ing arrangement of the hollow shaft 64 and shaft 51 is necessary, owing to the increased distance between the'center of the gear 20 and the center of. the shaft 15 of the lower roller 16 of the wringer.

By means of the set screw 65, the pinion gear 68 is always in engagement with the pinion gear 21, whether the lid or support 5 of the washing machine is open or closed.

Thus the hollow shaft 6d is always being driven with the gear wheel 20, thus driving the hollow shaft 64 and shaft 51.

When it is not desired to operate the wringer, the operating arm 59 may be left in its central vertical or neutral position, where the clutch member 55 will not engage either of the pinion gears 50, thereby allowing the shaft 51 to move freely inside the pinion gears 50, and not operating the bell 30 by Letters Patent 15:

shaped bevel gear 45, which operates the wringer.

- It is readily seen by referring to Fig. 3 that when the lid or support of the washing machine is raised, the center of the gear wheel 20' is considerably lower than it is when the machine is closed. This, however,

does not affect the shafts 64 and 51, inasmuch as the shield disk 47, which carries the bearings 48 for the shaft 51 is loosely mounted on the shaft of the wringer, and

I is thereby allowed to rock upon said shaft and conform itself to the proper angle, to registerwith the shafts 64.- and 51. The weight of the mechanism is practically all placed at the ivoted point of the lid or support 5, there y allowing the lid to be raised with little effort and balancing same in the open position, as well as in the closed. The motor 18 is mounted above the water line of the washing machine, thus preventing any water from falling thereon and interfering with theoperation of the motor, but if desired the motor may be differently mounted upon the machine.

Many'modifications of my invention may be made without departing from its spirit and scope, and I do not wish to be confined to the exact'details shown.
