MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed October 17 1906. Serial No. 283.167.

To all whom it may concern:

Be it known that I, WILLIE D. WHITNEY, a

ing is a specification.

This invention relates to mechanical movements, and has for its principal object to .provide mechanism of simple construction whereby a simple oscillatory movement of a revolubly-mounted member in a horizontal plane may be transformed into vertical reciprocatory movement of such member.

, A further object of the invention is to provide a device of this type in which the parts y adjust themselves tory member, and, further, to so construct the parts as to. permit their operation with minimum frictional resistance and wear.

With these and other objects in view, as

' will more fully hereinafter appear, the invention consists in certain nove features of construction and arrangement ofparts hereinafter fully described, illustrated 1n the accompanying drawings, and particularly pointed .ment constructed in accordanoe with the invention, the section being taken on the plane indicated by the line 1 1 of Fig. 2. Fig. 2 is a lan view of the lower portionof the mechanism, the oscillatory upper member being detached and the parts drawn'to a somewhat lar er scale. I

imilar numerals of reference are employed toindicate corresponding parts throughout both fi ures of the drawings.

The ase member 10 comprises a central hub having a plurality of equidistantlys acedradially-extendingarms 11, and from the bottom of the hub-extend standards 12,

which may rest on-or be attached to supports of any desired construction. At the outer ends of each of thearms 11 is arranged a pair plane.

lines struck from the vertical axis of themember 10. The two flanges are formed integral with the arm and are connected to each other by a web 16, the web being cast with the flanges and forming inconnection therewith a housing for the lower portion of a roller 19, that is provided with a pair of journals 20- and 21 on its outer and inner faces, respectively, the journal 20 restin on the flange 15 and the journal 21 on the ange 14." These journals are free to roll on the bearings-surfaces of the flanges and are held from displacement by upturned lugs 22 23, formed at the ends of said flanges, the inner faces of each pair of lu s 22 23 being on a radial line a from the vertlcal axis of the member 10, while the periphery of the roller is'tapered and is also arranged onlines that are radial from the vertical axis of. the shaft 10 as viewed in plan. The horizontal axis of each roller and its two journals is designated by the dotted line a) in Fig. 1, and the peripheries of the roll and thetwo journals 20 and 21 are arranged on lines that radiate from the point of intersection of its horizontal axial inc and the vertical axial line of the member 10. The bearing-surfaces of the two flanges are also arranged on a radial line extending from this intersecting point, so that the bearing-surfaces of'the inner flange 14 will be slightly higher than the bearing-surface of the outer flange 15, and the diameter ofthe,

lugs or sto s at the ends of the flanges and nals will remain in a constant horizontal The inner faces of the lugs are arranged on curved lines that merge into the horizontal supporting-surfaces of the flanges, so that the journals are free to turn in case the rollers travel the full limit of movement.

The member .10 is provided with a centrally-arranged opening for the reception of a vertically-disposed spindle 25, that depends from an upper oscil atory member 26, said IOC member having a central hub portion 27 and wardly extending cam-flange. 30, thelowfer r,

"point being indicated at y in Fig. 1. I

' Undernormalcon'ditionsthe weight of the' upper member 26' resting on the roller'will cause said upper member to move by gravity until'thepoints y. of the cam are midway between each two rollers, and the parts will naturally'tendto assume this positionif left free. a fixedprop'ortional relation-to 'each' other that is to 'say, the relation between the oil'- cumference oftheournal 20 andthe bearingsurfa'ce of the flange 15- is the same asthe relation between the circumference of the roller 19 and the length of each one of thecam f'aces, so that under ordinary conditions of use the oscillation of the upper member26, which may be effected either manually or 'bysuitable mechanism, will not bring either of thejournalsagainst the stoplugs at the'endsofthe flanges; The points of the cam-surfaces are arranged at one hundred and twenty-degreesfrom each other, and the normal extent of oscillatory inovementis'throughan'arcapproximately'ofone liundreddegrees, so'that thepoints'y of the camswill'not ride over the-roller, and the journals of the latter will therefore play between thestopl ugs without coming into contact therewith. In case of accidental excess of movement of the parts, however, no damage'results, and the upper member maybe revolved to'an extent greater than one hundred and twenty degrees, so that the points y of the campass over the rollers, but in such cases the journals are merely driven against the 'stop lugs and rotate against said lugs, thefriction being of course increased, but not to 'such'an" extent as to result in any injurious wear.

The object sought to be obtained is transformationof the'oscillatory movement of a revolublemember'ina horizontal plane into vertical reciprocatory movement ofthe same member, and it"will be seenthat'this may be effe'ctively'accomplished by oscillating such uppermember'26, the'member' and its spindle25 being'raisedand lowered to an extent proportioned to theangular' movement of the s'aidup'per member.

The device forming the subject of the presentinvention while of value inconnection with many dilferent mechanisms is found of especial value in washing-machines of thatgener'al'typ'e in which the tub or one of The surfaces in rolling contact bear the rubbing members receives both oscillatory and vertical reciprocatory movement.

Havingthus described'the invention, what isclaimed is I 1. In a mechanical movement, a base member, and an upper member, the latter being arranged for oscillatory movement, around a vertical axis, and for vertical reciprocatory movement, there being cams arranged on the under side of said upper member, and rollers supported by the base member, and on which the cams rest, theextent of vertical play of the upper member being proportioned to *the extent of oscillatory movement imparted thereto.

2Q Ina mechanical movement, acanr-carrying member arrangedfor oscillatory movement around a vertical axis, and meansfor imparting vertical reciprocatory movement thereto comprising a base having a plurality of'pairs-of spaced flanges, rollers =having'p'ro jecting journals resting on said flanges, the cams carried by said member resting onsa'id rollers, the extent of vertical reciprocatory movement of the member being proportioned to thearc of oscillation;

In amechanicalmovement, a'base member'prov-ided with a plurality of pairs of flanges arranged at equal radial distances from the verticalaxisof said member, said flangesbeing d isposed'onar'cuat'e lines struck from said axis, rollers-havin journals resting on the flanges, an os'cil at'ory member 'havmg cams that rest on said rollers, said oscillatory member having a pendent shaft or spmdle extending througha guiding opening inthe'base member.

In combination, a base member comprising a hub having a centrally-disposed opening and provided with a plurality of equidistantly-spaced radiating arms, verticalfiangesarrangedatthe outer ends of the arms, said flanges being disposed in. pairs and arranged on curved lines struckfroln the vertical axis of said opening, the ends of the flanges being provided with upturned lugs or stops, the inner edges of WlllOh are also on lines radiating from said axis, a plurality of rollers arranged between the flanges and having projecting journals resting thereon, the axes of the journals and rollers being in a common horizontal plane that intersects the vertical axis of theopening, an upper member mounted for osolllatory movement and having a peripheral flange, the lower face of. a
