To all whom it may concern.-

Be it known that I, THOMAS J. WINANs, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Operating Mechanisms, of which the following is a specification.

My present invention relates to improvements in o erating mechanisms, and has for its object the provision of machinery and devices for receiving and transforming a rotary motion of some of its parts into an oscillating or reciprocating motion of some of the other parts of the machinery.

A further object is to improve the machinery in' certain particulars and arrangements and to provide spring-cushions to take up the shock of the motions of parts of the machinery to prevent jarring to the oscillating parts of the machinery and wear on the same.

The invention consists in certain combinaf tions and arrangements of rotating mechanism and in certain combinations and arrangements of oscillating devices so connected that the rotary motion received by the rotating mechanism is transferred to and transformed into the oscillating motion of the latter mechanism.

In the accompanying drawings I have illustrated one example of the physical embodiment of my invention, illustrated as applied to a washing-machine for clothes and constructed according to the best mode I have so far devised for the practical applications of the principle of the invention.

Figure 1 is a view in side elevation of my operating mechanism, illustrated in combination with a clothes-washing tub. Fig. 2 is a plan view of the oscillating mechanism, showing the rotary shaft and parts of the frame in section. Fig. 3 is a vertical central section of the oscillating mechanism, some parts being in full lines. Fig. 4 is a bottom plan view of parts of the oscillating mechanism. Fig. 5 is a perspective view of a portion of the oscillating shaft and a .member thereon for imparting motion to the oscillating devices or machinery. Fig. 6 is a perspective view of one of the members of the oscillating mechanism. Fig. 7 is a sectional view taken in the direction and looking at 8 is a vertical central sectional view of the rotating mechanism of the machine, and Fig. 9 is a sectional view on line 8 8 in Fig. 8.

Referring to the drawings, the numeral 1 designates a stand or table forming a support for the machinery; 2, thel legs of said table; 3, a horizontal frameiece secured to the tato the piece 3; 5 and 6, upright frame-pieces, and 7 an upper horizontal frame-piece, the before-mentioned pieces forming a substantial and rigid frame for the support of the machinery.

The sectional casting 8 is sup orted by and connects the frame-pieces 6 and 7, said casting forming a casing for the gear-wheels contained therein and provided with two flanges 8 and 9, which are connected by bolt 10 with the metallic plates 11 on the horizontal frame-piece 7. Within the casing 8 the transverse shaft 12 is journaled, and Said shaft carries a driven pulley 13, which pulley may be driven by a Water-motor. The shaft 12 is not journaled directly in the casing 8, but has its bearings in a cam-sleeve or'eccentric bearing-bar 14, and the bar or sleeve 14 is in turn j ournaled n the walls of the casi 8 and rotates freely therein, the shaft 12 being of course free to rotate in the sleeve or hollow bar 14. As seen clearly in Fig. 9, the shaft 12 is located eccentrically in the bearingsleeve 14, and at the bifurcated end 14 of the har a lever 15 is pivoted at 16. A spring 17 is seated within a recess in the bar 14 and to press it outwardly. By means of this lever the hollow bar or sleeve 14 may be turned in its bearings for a purpose to be described and when so turned may be located in adjusted position by the lug 18, which enters either of the two openings 19 or 2O in the cas- A worm-gear 21 is formed ri ld with the shaft 12, and this worm in t e positions shown in Figs. 8 and 9 is in mesh with a horizontal gear-wheel 22, rigid and rotatable with the vertical shaft 23. This shaft 23 is supported in bearings 24 and 25, which are secured by bracket-arms to the upright framepiece 6 and also has bearings in the casting 8. Thus by means of the driven pulley 13 the shaft 23 is rotated through the medium of the shaft 12, worm 21, and gear-wheel 22.

bearing against the end of the lever 15 tends IOO journaled in the casting 8 I locate a transverse shaft 24., upon which is mounted the vertical. gear-wheel '25. A. second gearwheel26 -is iocatedrat .t'heend of the'shaft 24 and wheel 6 meshes with the gear-wheel 27 on driven shaft 28. Assuming the .hollow bearing-bar 14 to be in the position shown .in 49, if the handle or lever 15 be turned to vertical position so that the lug 18 engages openin 20, Fig. 1, the worm-gear is disengaged om the gear-wheel 23 and made to mesh with .the 'teeth of the vertical .gearwheel '25. 'In this position of the 'eccentric hollow bearing-bar `the ro'tary motion of the driven pulley is transmitted through Ithe worm-gear, .gear-'wheel 25, shaft 24', gear 26,

gear`27, 4and shaft 28, thus Vdrivingthe shaft 28 and 'operating said shaft for any desired propose-aS, for instance, a 'clothes-wringen .At `its lower end the vertical rotary shaft 23 isprovidedwith a crank-'piece 29 ,clamped thereon '"by means-oi |thebolt or screw 30. A connectingrod 31 connects 'the Icrank-arm'29 with alever-arm 32 loosely mounted lon the vertical'pintleSB. This tle`33 is sup orted andadaptedto .parta ly rotate ina "hearing#A 'iece'34,which1isin `turn su ported cen- 'tral yfoffth'estand or *table 1. pon the pintle and 'located above the lever-arm 32 is mormted f'atriangular-shaped plate 35, `which plate is rigidly secured to the pintle or ost 331a'nd turns therewith, and above'the pllat'e 35 a second similarly-sha ed p'late '36 'is loosely'mountedonthe gpint e. A'spider for su 'ortingthe vessel or receptacle to be oscil a'tedis'composed of'thelthree arms 37, 38, and '39, and 'these *three arms lare Lheld be- `tween *the clamp-plates 35 'and 36 b the the 'spider-'arm v39 is 'directly'connected by'a spring-41 to the lever-'arm 32, and the llever- A in turn connected with the rod 3`1 'it will lbe understood thatthe spider is oscillated "by the movement of rod 31, the spring '41'makinga .ilexible or cushioning connecti'oubetweenthe armand spider, `but such aconnec'tion'as will give suiiicient direct impetustofthe spiderin' order to impart a swingmg -or oscillating movement thereto on 'the pintle'or post 33.

rThe Spider-arms are held rigid `with the pintle'or'post bymeans ofthe two triangular clamplates vand the clamping-nut 40, as'describe Thus when the :rotary motion Vof the'crank-arm 29 is'transformedin'to a reciprocating motion of the rod 31 saidvrod swings the ilever-arm 32, which'is loose on the shaft or rp intle,and the spring 41 ,'being under high tensionfimparts 'the swinging or oscillating motion to the-spider with'an easy start and reverse. 'To Afurther cushion thedevices vas they start land reverse :in their oscillation, I provide 'an obstruction piece or plate 42, whichis-mounte'diloosely on'the pintle-33 and suspended' ateither endby'the springs 43 and 44, which springs are respectively hooked over the'brackets 45 and 46, secured to the frame-piece. As more 'clearlyl shown -in Fig. 4, this obstruction-plate 42 fisproyide'd with a pair of shoulders 48 and 49, located'at the ends of an arc of a circle having the pintle 33 as its center. On the'under side of the rigid clamp-plate l35 a depending lug is formed, preferably integral therewith, and this lug, projecting downwardly through the slot or opening 51 in lever-arm 32, is in position to swing backward and forward with't'he oscillation of the clamp-plate and spider. Now-as the spider swings l'or'osc'illa'tes lwith the ypin't'le 33 as a center at 'the extreme 'of 'its-swinging movements 'the lug 50 `comes incontac't with one or the'other 'of these shoulders 48 or'49, and as the plate 42 Yis suspended by "the springs, as before described, the motion of the spider as it stops is not'only cushionedby the 'elasticity of the springs, but the motion of reversing and starting in the reverse direction is assisted by the tension ofthe springs, thus 'providing ra forward an'dbackward swing motion about the center'of -t'he vmechanism without shocker jjar and avoiding lall jerks ofthe'mechanism.

In-o eration, assuming the mechanism to bein the positions :illustrated in *the lseveral figures, the pulley 13 is ldriven by suitable power, and through the medium y'ofithe wvorm wheel or'gear 12, gear-wheel 22, aud-shaft'23 the crank-arm is horizontally rotated, which reciprocates the rod '31, and this 'rod yin 'turn imparts the swin ing'or'oscillatin'g motionto the spider throug the'connections'describe( i, the springs actin to take 11p all lost motion and revent shocks or jars iin the operation-'of the' evice.

From the above description, 'takeninfconnection with the drawings, it becomesevident that I 'have produced a 'mechanism whichfullsall'the conditions set'forthasth'e purpose or objects -of :the invention, .'providing an easy-running and efficient machinery for the purposes set forth.
