SAMUEL '1. WHITE, OF DAVENPORT, IOWA.

MECHANICAL MOVEMENT.

Application filed January 7, 1915.

To all whom it may concern:

Be it known that I, SAMUEL T. WHITE, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Mechanical Movements, of which the following is a full, clear, and exact description.

My invention relates to improvements in mechanical movements for washing machines, and particularly to motor-driven washing machines having wringer attachments applied thereto.

The object of my invention is to provide new and improved means for actuating the the same time increase the power.

These and other advantages I obtain by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings: Figure 1 isa side elevation of a washing machine tub having my improvements applied thereto. Fig. 2 is a similar view looking at the machine from a view point at right angles to that shown in Fig. 1. Fig. 3 is a vertical transverse section taken on dotted line 33, Fig. 2. Fig.

able lid B, one side of which is straight and hinged to a stationary top-strip a upon which latter the tray for a wringer C is mounted.

The dolly D of this machine is mounted and longitudinally adjustable on a sleeve d, and this sleeve surrounds the upper end of a vertical tube E the lower end of which is clamped in the center of the bottom of the tub by nuts or arbors e, e. The upper end of sleeve 01 is secured to a rotary reciprocable shaft 2 which extends down through the tube E and has its lower end journaled in bearings 3 made in one piece with the lower arm/l of a bracket 5 the supportingplate of which is suitably secured to the underside of the bottom of the tub.

Thus far the description pertains to the construction of a Washing machine that is very common. The lower end of shaft 2 has a sleeve 6 secured thereto and constitutes a journal therefor that extends through bearings 3, and just below said bearings it is provided with a circumferential flange 7 that prevents said shaft from being moved upward. The upper end of this sleeve,

above the bearings, is formed into the counterpart 8 of a clutch. Above this counterpart a pinion 9 is loosely mounted on shaft 2 the lower face of which is formed into a clutch-member 10 that is the obverse of counterpart 8 which it is adapted to engage. This pinion is raised and lowered on shaft 2 a limited distance in order to enable it to engage and disengage from counterpart 8 by means of a treadle 12 that consists of a bar that is fulcrumed to the hanging portion of bracket 5, and has its longer branch extend straight outward beyond the circumference of the bottom of the tub so that the hand can be used to depress it. The other shorter inwardly extending arm of treadle 12 passes alongside of pinion 9 and has two lips projecting laterally therefrom that embrace the edge or marginal portion of pinion 9, and when the outer arm of said, treadle is depressed disengages pinion 9 from sleeve 6, and when the pressure on the outer arm of the treadle is raised pinion 9, through the tially in the same plane thereas.

a guide-opening or recess 15 made in the adjacent edge of the hanging portion of bracket 5, which latter, preferably, has an anti-friction roller therein which the back of the rack engages. The end of the rack farthest from pinion 9, that is, its outer end, is pivoted to the upper end of a link 16 whose lower end is pivotally mounted on the adjacent end of a horizontally disposed open frame or platform 17, and the construction of the upper end of said link is such as to enable the upper end of a connecting-rod 18 to be pivoted thereto. Platform 17 comprises a cast metal open frame that is connected to the inner sides of and braces the legs of the washing machine tub a suitable distance below the bottom of the same, and it is provided with integral posts 19 and 20 that have alining bearings in their upper ends for the horizontal shaft 21 of a large ear 22 which latter has a wrist-pin projecting therefrom to which the lower end of connecting-rod 18 is pivotally connected.

Gear 22 is engaged by a pinion 23 that is journaled in bearings 24 and 25 depending, respectively, from the underside of said platform and from the outer end of an arm 26 projecting from platform 17 substan- Shaft 27 extends beyond pinion 23 and has a concave pulley 28 securely mounted thereon. This pulley 28 is driven through the medium of a belt 29 which engages and derives motion from a smaller concaved pulley 30 on the adjacent end of the shaft of a motor F. The slack of belt 29 is taken up by a suitable belt tightening contrivance comprising an idleconcaved' or donkey-pulley 21; and L-shaped arm 32 in the upper end of thewertical branch of which said pulley is journaled, and the opposite end ofthe branch of which is pivoted in a lug 33 depending from the platform. The horizontal branch of arm 32 has a lug 34 projecting laterally therefrom which is engaged by an expansion coil-spring 35 interposed between the same and the underside of platform 17. If desired, a guidepin 36 whose upper end is suitably secured in platform 17 may be employed which passes down through the bore of spring 35 and through a lug 34 projecting from arm 32 for the purpose of retaining the spring in place, which latter keeps pressing down on arm 32 and causes pulley 31 to take up the slack of belt 29.

Shaft 21 extends beyond bearing 20 and just beyond a bearing 37 in the upper end of the same vertical member 0a in the lower end of which bearings 25 are made. Between these bearings, 37 and 20, shaft 21 has two suitably separated corresponding mitergears 38 and 39 securely mounted thereon.

These miter-gears face each other and their uppermost segments are engaged by a miterpinion 40 that mounted on the lower end of a vertical shaft 41 journaled in bearing made integral with the ends of a vertically disposed floating channel shaped. sleeve 42 the lower end 43 of which is bifurcated and has an, integral transverse horizontal member 44 connecting the ends of its bifurcations, the center of length of which is provided with a boss that surrounds shaft 21 and the ends of which project beyond said bifurcations and forms lugs 45. The bifurcations of this end 43 is seated in a. transverse slot or recess made in the center of length of the dome of a longitudinally elongated casing 46 which latter has lugs projecting outwardly from it on either side of the ends of said recess that are attached to lugs 45 of the end of the sleeve by means of bolts, substantially as shown in Fig. 2 of the drawings,

Casing 46 is rounded on top and at both ends; its longitudinal sides extend straight down to its lower edges; it extends slightly over bearings 20 and 37 at each end and its ends are recessed for the accommodation of said bearings.

Sleeve 42 extends upward above the top of the tub and its upper end is likewise bifurcated and the ends of these bifurcations 47, 47, are pivotally connected to the sides of a bell-shaped housing 4 8 that has an internal axial bearing boss 49. This boss is mounted on the extended end of the shaft 50 of the lower roller of the wringer C, and is retained thereon by a collar 51 on the adjacent extremity of said shaft. Shaft 41 extends longitudinally up through sleeve 42 and has bearings in the upper end thereof in addition to that in the lower end, hereinbefore referred to, and on its upper extended end it has a miter-gear 52 that meshes with a corresponding miter-gear 53 securely mounted on the wringer-shaft 50.

Shaft 41 will revolve either in the one direction or the other according as gear 40 engages miter- gears 38 or 39, and will remain stationary when not in engagement with either of said gears. The sleeve 42 is oscillated from the center of its pivotal connection with housing 48 by means of a horizontal rod 54, one end of whichis pivoted between lugs 55, projecting from the longitudinal edges of sleeve 42 below the plane of the lower edges of the tub and extending from thence under the bottom o-f'said tub and beyond the opposite side thereof where its adjacent end is suitably connected on a crank 56 on the lower end of a vertical rockshaft 57. This rock-shaft is journaled in brackets 58 and 59 the supporting screwplates of. which are secured to the side of the tub and the upper bracket 59 has a horizon-' upper bearings and has a crank 63 with which to turn it, and the boss of this crank I has three flat faces 62, one of which is located diametrically opposite from where the arm of the crank projects and the other two onopposite sides and at right angles to the first-mentioned face.

A comparatively strong expansion spring 61 is seated in the bore of seat 60 and extends out of the same and engages the boss of the crank and presses so strongly against the faces thereof that it will hold shaft 57 against voluntary movement. When shaft 3 57 is moved so as to swingsleeve 42 to bring pinion l0 into engagement with gear- 39 shaft 41 will turn in one direction and spring 61 will engage one of the opposite faces ofthe boss-crank and will hold pinion 49 and gear 39 in engagement. When shaft 57 is turned in the direction so as to bring the spring intoengagement with the cen- -tral face of the boss of the crank, pinion 40 will be held'out of engagement with both gear-s39 andet8 and shaft 41 willremain stationary, and when shaft 57 is turned up so as tobringspring 61 into engagement" with the face of the boss of the crank opposite to that first mentioned in this paragraph, pinion 40 will engage gear 38 and shaft 41 will revolve in the opposite direction.
