Specification of Letters Patent.

' Application filed December 14, 1911. Serial No. 665,622.

To all whom it may concern Be it known that I, CHARLES J. MABTH, a citizen of the United States, residing at St. Louis, Missouri, have invented a new and useful Improvement in Gearing, of

which the following is a specification.

This invention relates to gearing, and is especially adapted for use in washing machines and in washing machines and wringers combined, though it is useful in other combinations and for other purposes as well; and it consists of the novel construction, combination and arrangement of parts herein shown, described and claimed.

My present invention is particularly adapted for use in operating washing machines and other machines which require operation alternately in opposite directions.

In washing machines of a well-known type, there is a cylinder arranged to contain the articles to be washed; said cylinder being revolubly mounted in a receptacle arranged to contain the water. Superior results are obtained ,by rotating the cylinder alternately in opposite directions so as .to cause the articles to rub against the inner surface of the cylinder while being agitated by movement through the water.

Since my invention is especially adapted for use in operating washing machines of the type referred to, I have illustrated one embodiment of my invention combined Wit-h such a machine.

An object of the invention is to produce an improved gearing in which there is a driving shaft arranged to berotated constantly in either direction, and carrying two gears loosely mounted thereon and meshing with another gearcontrolling the driven mechanism, in combination with improved clutch mechanism, operating automatically,

y of said driving shaft and said Wringer or'.

when the drivin shaft is in operation to lock first one 0 said two gears and then the other on said driving shaft, thereby caus' said driven mechanismto be operated fiernately in o posite directions.

Other objects involve the use of the drivingshaft to operate other mechanism, such, for instance, as a wringer, and convenient clutch devices for controllingthe operation other driven mechanism. Other objects and purposes 12. A rod 15 is supported in bearin of the inven.- tion will appear from the following description, reference being made to the accompanying drawings, in which- Figure l is a plan view of one embodiment of my invention applied to and combined with a washing machine and wringer. Fig. 2 is an "end view of the washing machine and wringer showing the gearing in combination therewith. Fig. 3' is a side elevation of the gearing, the tub and cylinder of the washing machine being in section, and the cover or case of the gearing being also in section. v

The washing machine of the type illustrated includes a receptacle 1 adapted and arrangedto contain the water, and having attached to the inner side of one of the end walls thereof "a bearing2. The other end wall of the receptacle has a bearing in which a. shaft 3 is journaled. A socket 4 is attached to the inner end of said shaft and is rotated with said shaft when the latter is driven by the gearing and driving mechanism. 'l'he cyllnder 5, which is arranged to receive and contain the articles to be washed, has a trunnion 6 on one end to rest and revolve in the bearing 2, and on its opposite end said cylinder has a polygonal trunnion or projection Tarranged to extend into and formlocking engagement with the socket 4. Thus the cylinder 5 will be rotated with the shaft 3, and change in thedirection of rotation of the shaft 3 will also change the direction of rotation ofthe cylinder.

In the type of washing machine shown,

wringer mechanism 8 is supported by the receptacle 1. The shaft 9 of one of the wringer rolls extends beyond the frame of the wringer and has a sprocket wheel 10 loosely mounted thereon. *A clutch member 11 is splined on the shaft 9 and constitutes means for locking the wheel 10 to said shaft,

and is operable to release and permit said wheel to run idle when desired. A spring 12 encircles the shaft 9 between the clutch l1 and the frame of the wringer and actuat'es said clutch member toward the'sprocket wheel. A lever "13 pivoted on a support 14 Patented Oct.29,1912.

embraces the clutch member 11 between two i 1 arms of said-levensaid arms extendin into a groove in-said clutch, and is-opera' le to release the clutch in opposition to the spring 16 on: the wringerframe'and' has on its inner end a cam 17, The cam 17 is'close to the may be driven.

A hearing casting. 20 is secured to-one end of the receptacle 1 and a short shaft 21 is revolubly supported thereby. The shaft 21 is the shaft for driving the remainder of the gearing, including the parts coiiperati'ng with the wringer, and is provided with a belt wheel or pulley 22 whereby said shaft A small gear 23 (Fig, 1) is rigid on the shaft 21 and meshes with a relatively larger gear 24 which is loosely mounted on a shaft 25 journaled in hearings in the bearing casting 20. A clutch member 26 is slidably mounted on the shaft'25 and is operable to lock the wheel 24 to said shaft, or to release said wheel and permit the same to rotate freely and loosely on said shaft, as desired. A spring 27 which encircles the shaft 25 is effective to actuate the clutch to closed adjustment. A lever 28 pivoted on the bearing casting has arms entering a notch in the clutch member and is operable to open the clutch in opposition to the spring 27. A rod 29 has a cam 30 similar to the cam 17 for the purpose of operating the lever to open-the clutch said rod being provided with a hand wheel 31 for purposes of operation. Two-gears 32 are loosely mounted on the shaft 25 and are in constant mesh with a relatively large gear 33 on the outer end of the shaft 3. A clutch member 34is keyed on' the shaft 25 between the gears 32 and is slidable from engagement with the hub-of one of said gears to engagement with the other. A lever 35 pivoted at 36 has a yoke embracing and engagin the clutch member 34: and is operable to move said clutch member-from one to the other of said gears 32. Assum-' ing that the clutch 26 is closed, the shaft 25 will be rotated by power applied to the wheel or pulley 22. The gear 32- which is engaged by the clutch 34: will also be rotated andmwill drive the gear 33 and shaft 3, thereby rotating the cylinder 5. The lever 35 operates against a plunger or latch I device 37 yieldingly carried in a support 38,

and is efiective to latch the lever and yieldingly hold the clutch 34 closed with either one of the gears32, but will 'ermit movement of said lever to move said clutch from one to the other of said gears.

A pinion 39 rigid on the shaft 25 meshes with a relatively larger gear 40 revolubly mounted on a supportingaxle 41. i A pinthe yielding latch or clutch Wheel.

Loaaseo vbearing casting 20 above the shaft 25, so

that said shaft will be driven whenever the shaft 25 is rotated. The shaft A l carries a casting 45 having two disks integral therewith, and a cam 46 integral with the inner face of each disk. The upper end of the lever'35 extends between the disks which carry the earns 46, and has a roller 47 to roll against the faces of the disks. shaft 25 is rotated the shaft 44 will also be rotated, and the cams 46'will operate the lever 35 so as to engage the clutch 34- with-the gears 32 alternately. The gears 32 being in mesh with the gear 33 on opposite sides of its axis will rotate the gear 33 in opposite directions. Thus, the shaft 25 being in constant-rotation inone direction will automatically and alternately rotate the cylinder 5 first in one then in the opposite direct-ion, such alternate operation being maintained continuously.-

The upper end of the plunger or latch '37 is wedgeshaped, and the lower endof the -When the" direction and lever 35 is similarly formed, so that the ate said lever the distance required to completeclosing the clutch 34 after said lever is started by the cams 46. It will be observed that, in the embodiment shown, the cams 46 are arranged to operate the lever only partj of the dist'ance'required to move the clutch 3% from one gear to the other; and that the cams merely serve to open the clutch, while to complete the movement of the lever to close the clutch. Therefore, there is a directoooperation between the clutch openers 46,

and the clutch c'loser '37 in eifectingthe reciprocal rotation of the shaft 3 and the cyl' inder r'ate the lever 28 and open the clutch 26 5. Manipulation of therod 29 to op stops and renders the gearing inefiective in so far as the operation of the shaft 3 and the clutch opening and closing devices are conerned.

The same power may be used for operating the wringer 8 either concurrently with or independently of the gearing'fordrivin the shaft 3. Asprocket wheel/18 1s rigi with the gear'wheel 24 and rotates with said sprocket 48 proper manipulation of thejrod 15 to open or closetheclutoh llfthe wringer may be operated or maintained idle, as desired. Op-

eration of the wringer is independent of any adjustment of the'clutch 26, and is not/affected by operation or inactivity of the A. chain 49 'entrai'ns the said with the sprocket 10 so that by L05 closer 37 serves gearing and reversing mechanism which directly control the shaft 3.

The entire gearing mechanism may be shielded and incased in a housing 50 which is attached to and supported by the bearing casting 20. This prevents the clothing of the operator, and other articles, from becoming entangled in the gearing and is of material benefit where the gearin is employed on washing machines and'o er machines where there is opportunity for and danger of entanglement.

I have shown my improved gearing combined with a washing machine to which it is especially-adapted, but it is obvious that it may be employed advantageously for operating any mechanism where reciprocating or rocking or oscillating movements are required. I do not confine myself to use of the invention in any particular embodiment or combination.

I am aware that there may be variations and alterations in the arrangement of the parts, to meet difierent requirements and conditions, without departure from the nature and spirit and scope of the invention. I do not restrict myself to specific features, but contemplate such changes and adapta tions in arrangement and construction as will render the gearing most useful and serviceable for the purposes intended.
