OPERA'II N'G MECHANISM FOR WASHING-MACHINES.

' Application filed August 2, 1909. Serial No. 510,780.

To all whom it may concern.-

Be it known that I, GUSTAV l. Mnvns, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Operating Mechanism for Washing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and. to the letters of reference marked thereon, which form a part of this specification.

. This invention relates to an improvement in mechanism for operating washing machines wherein the beater within the tub or receptacle is given a rotary reciprocating motion, and more particularly to a high speed mechanism operating through a flywheel to diminish the work of the operator I after the parts have been started in motion.

The invention consists in the matters here:

inafter set' forth and more particularly pointed out in the appendedclanns.

In the drawings illustrating the invention: Figure l is-a view in vertical cross section of ti -washing. machine embodying my invention. Fig. 2 1s a plan View of thesame; "Fig. 3 is ahorizonta l cross-sectional view taken upon line 3 3 of Fig. 1. 4 is a detail sectional view taken upon line of Fig. 2.. Fig. 5 is a detail crosssectional view taken upon line 55 of Fig. 2. Fig. 6 is a fragmentary detail view of parts relating to this invention.

In the drawings, 5 designates a washing machine tub of the usual form mounted upon supporting legs 6, 6 and provided with a hinged lid 7. Located centrally of said lid is a. base-plate 8 provided with a vertically arranged bearing 9 which extends downwardly through the lid and in which is rotatably supported an operating shaft 10. Said shaft depends into the tub 5 and has therein secured to it an agitator 11 of 'any usual form. Upon the upper end of tl'ieI'o'pcrating shaft-10 is mounted an operating gear 12 which meshes with a segn'iental'gear l3. ttaulseguiental gear 13 is pivotally supported upon a horizontally arranged stubshaft 14 carried at the'upper end of a three arm bracket 14* formed upon and rising from the base plate 8. A socket 15 is formed upon the hub of the segmental gear 13 to receive an actuatin lever 16.

Secu'red'to the edge of the tub 5 is an an- Fig.

gular supportingbracket,20 upon which is formed a gear casin 21 supporting a bevel gear 22. Said bevel gear '22 is operatively connected. by a pitman 23 withthe segmental gear 13 and is 1n mesh with a bevel gear 24 located in said casing 21, and mounted upon the upper end of a vertically arranged shaft 25 which is operatively connected with a fly-wheel in the manner hereinafter described. As shown in Fig. 5, the pitman 23 is provided with a downwardly opening notch 23 which engages an outwardly extending stud 26 secured to the segmental gear 13.

27 indicates a washer interposed between the outer endof the stud 26 and the adjacent face of the pitman 23, said washer being held in place by a cotter pin 28 extending through said stud. Said pitman is held in place while in operation by a weight 29 which is swingingly supported upon the segmental gearv 13 and is adapted to bear upon the up er edge of saidpitman nearthe inner endt ereof. For disconnecting the pitman toopen the lid of the tub the weight 29 isswung upon its pivot and the inner end of said pitman is lifted. from the stub 26 and swung. outwardly. At its outer end said pitman is curved upwardly to clear the tub while in operation.

As shown in the drawings (Figs. 1 and 3) there are mounted upon the: supporting legs 0, 6- below the tub 5 two cross-bars 30, 30 which cross each other in the vertical axis of the tub. Mounted'upon said cross-bars and extending outwardly therefrom is a base-plate 31 provided on its outer end'with an upwardly opening recess 32 adapted to receive and rotatably support the lower end of the'vertically arranged shaft 25. Upon.

upper end with a cone 36.,whichrides upon lnill' hearings'37, 37 carried in a-cup .38 serured'to the central portion of the tub bottom. .39 indicates a horizontally. arranged ball bearings-34, 34 is provided near its flywheel mountedupon said stub shaft 35.

" A pinion 40 on the hub of the fly wheel nieshe with a gear 41 which in turnmesglies with a gear 42 mounted uponthe lower end of the verticallyv arranged shaft 25. The

f gear 41 is mounted upon a'vertically arranged stub shaft supported near the central portion of the base plate 31. The

gear 42 projects beyond the edge of the tub 5 and is preferably inclosed'in a casing 46 secured to the side of'the tub and the end of the base plate 31.

In the operation of the machine/the rocking motion of the hand lever 16 is translated into rotaryreciprocating motion of the agitator 11 through the segmental gear 13 and the gear 12 and into continuous rotary motion of the fiy-wheel 39, by means of the pitman 23, the bevel gears 22, 2e, the-shaft 25, the gears 41 and 42, and the'pinion 40 on the hub of said fly-wheel. The proportions of the gears through which the rotary motion is given to the fly-wheel 39 are such that said fly-wheel will be driven at a high rate of speed and the momentum thereof serves to absorb the;shock of the reversals of the operating lever 16 and to insure the free and easy operation of the agitator. Moreover, said fly-wheel being mounted in ball bearin s will require but little power to start and maintain the same at its running speed.

I claim as my invention 1. Operating mechanism for washin mation'with a body, an operating shaft, a bevel gear secured to said operating shaft, a segmental gear in mesh with said bevel gear,

a rocking hand. lever secured to said segmental gear, a horizontally arranged fly-' wheel located beneath said body, a vertically arranged driving shaft mounted at one side of said body, a ear mounted upon the uper end of said riving shaft, a second gear i in mesh with said first named gear, a pitman connecting said second gear with said segmental gear, and gears connectlng the lower end of said driving shaft with the fly-wheel.
