GEARING FOR W ASKING-MACHINES.

To all whom it may concern: 1

Be it known that I, LEROY THOMAS, a citizen of the United States, residing at Mombaccus, in the county of Ulster and State of New York, have invented certain new and useful Improvements in Gearing for Washing-Machines, of which the following is a specification.

My invention relates to gearing for converting a continuous rotary movement into a reciprocatory-rotary movement, and has particular reference to means of this character which are especially well adapted to operate the agitating or rubbing element of a washing machine.

An important object of this invention is to provide means of the above mentioned character, which are simple in construction, and formed of a few parts, which are so arranged that they do not interfere with the operator raising the lid or cover of the washing machine.

A further object of this invention is to provide means whereby the operating lever may be angularly adjusted, to assume a convenient position for the individual operator.

A further object of my invention is to provide means of the above mentioned char acter, which are strong, durable, and operate in a highly satisfactory manner.

Other objects and advantages of this invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side view of a. washing machine, showing my gearing applied thereto, Fig. 2 is a plan view of the same, Fig. 3 is a side view of a washing machine, taken at a right angle to Fig. 1, parts of the washing machine being broken away for the sake of illustration, Fig. 1 is an enlargedperspective view of the operating lever and supporting bracket, and, Fig. 5 is a side view of the same.

In the drawings, wherein for the sake of illustration, is shown a preferred embodiment of my invention, the numeral 6 designates a main shell or casing of the washing machine, which is preferably circular in. cross-section and decreases in diameter upwardly. The upper end of the main shell or casing is normally closed by a vertically Specification of Letters Patent. Patented Aug. 18, 1914. Application filed June e, 1913.

Serial No. 771,467.

swinging lid or cover 7, hinged as shown at S.

Rig-idly mounted upon one side of the main shell or casing 6 near the upper end thereof, is an open frame 9, having an open .ing 10 formed therethrough, for receiving, the outer end of a rotatable stub-shaft 11. The inner end of the stub-shaft is rotatably mounted within a stationary bearing 12, hxed to the main shell or casing 6. Rigidly mounted upon the rotatable stub-shaft 1 1 is a fly wheel 13, which does not extend beyond the upper end of the main shell or easing 6, as shown. Disposed inwardly of, the fly wheel 13 is a small gear wheel or pinion 14E, rigidly mounted upon the rotatable stub-shaft 11, and engaging a large gear wheel or pinion 15, arranged there above. The upper large gear wheel 15 is rotatably mounted upon a stub-shaft 16, which is rigidly connected with the upper portion of the main shell or casing 6. Disposed upon the inner side of theupper large gear wheel or pinion 15 is a bevel gear 17, which is rigidly connected therewithto rotate with the same.

Rigidly connected with the upper portion of the main shell or casing 6 is a bracket 18, carrying a stub-shaft 19, upon which is pivotally mounted a segment 20, provided with a depending crank 21.

The numeral 22 designates an operating lever, the lower end of which is preferably forked to straddle the segment 20. The free end of the forked portion of the operating lever 22 is apertured, as shown at 23 for receiving the stub-shaft 19, as shown. The forked portion of the operating lever 22 carries a clamping bolt 21, which operates through a curved slot 25 formed in the segment 20. It is thus seen that by proper manipulation of the clamping bolt 24:, the operating lever 22 may be locked to the segment 20 at desired angular positions with relationthereto. Pivotally connected with the lower end of the depending crank 21 is a pitman 26, which is pivotally connected with the large gear wheel or pinion 15, as shown at 27. It is thus seen that by oscillating the operating lever 22, the same will effect the rotation of the large gear wheel or pinion 15. l

The lid or cover 7 is provided centrally thereof with a bearing 28, rigidly attached thereto by any suitable means. Rotatably The open gear 32 is rigidly connected and prefer ablycast integral with one end of a lever. 3a,

which is pivotally connected with the lid or .cover 7 by means of a stub-shaft Attention is called to the fact that the stub-shaft .35 is disposed between the ends of the lever 3ft, preferably approximately equi-distant from such ends. The outer end of the lever Bisprovided with a longitudinally extend- ;ing slot 36, receiving a crank pin 37, which is rigidly mounted upon. a bevel gear 38. This bevel gear is disposed below the lever 3 1 and is rotatably .mounted upon a stub-shaft 39, which is, suitably attached to the cover or lid 17. The bevel gear 38 engages the bevel gear 17, as shown.

The ,operation of the apparatus is as fol- .lows :-'l he operating lever 22 is oscillated which effects a continuous rotation of the large gear wheel or pinion 15, such rotation being-transmitted to the flywheel for maintaining the same steady. The gear wheel rotates the bevel gear 17, which in turn rotates the bevel gear 38. The bevel gear 38 oscillatesthe leverB, which is pivoted be tween its ends at This oscillatory move ment of the lever 34 causes the open gear 32 to .be ,reciprocated, such open gear in turn imparting a reciprocatory rotary movement .tothegear wheel 31. The reciprocatory rotary .movement of the gearwhee-l 31 is imparted to the agitatingor rubbing element 30. It is obvious thatthe cover or lid 7 may be readily raised or moved to its open position, such movement disengaging the bevel gears 17 and 38. Attention is called to the fact that 'thefly wheel 13 and associated elements are not mounted upon the cover or lid 7, whereby the weight of the same is taken off of the coverorlid, thus rendering it more easy to move the-cover or lid to its open position. Attention is further called to the fact that the number of elements mounted upon the cover or lid 7, to rotate the agitating or rubxbing element 30, is reduced to the minimum.

It isito be understood that the form of my invention herewith shown and described is 3110 be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resortled to without departing from the spirit of the invention or the scope of the subjoined claims.
