18 Claims.
'I'he present invention relates to washing machines of the type in which the washing is effected by an agltating member which is moved orbitally in the tub.
8 The object of my invention is to provide an improved construction and arrangement in washtional side elevation of avwashing machine embodying my invention; Fig. 2 is a top plan view of the agitating member and the driving arrangement therefor in section Aon line 2-2 of Fig. 1; Fig. 3 is a top plan view in section through the driving mechanism of the washing machine;
2o Fig. 4 is a top plan view of the washing machine; Fig. 5 is a perspective view of the washing machine. partly in section; Fig. 6 is a fragmentary sectional view of lthe bottom ol' the tub showing a construction in which the bottom 25 deiiecting vane iis formed integrally from the side and bottomv `walls of the tub; Fig. '7 is a sectional view showing a construction in which the top deflecting vane is formed integrally from the side Walls of the tub; and Fig. 8 is a sectional i view showing amodined construction in which the top deilecting vane is formed integrally from the side walls of the tub.
Referring to the drawings, the washing machine has a sheet metal tub I peripherally supported atits lower end on a rubber bead 2 on the upper edge\of a skirt 3 to which are attached supporting legs 4. A channel-shaped housi g 5, supporting the driving mechanism for the ashing machine, extends diametrically across the 4o skirt and is secured at each end thereto. The
supporting legs 4 are braced by struts 5c extending from the inside of each of the legs to a strap 5b secured across the flanges 5c of the housing 5.
A tubular post 6 is secured to the web 1 of the 45 housing 5, for example, by bolts extending through a flange 8 on the post. The post 6 projects vertically through a central opening in the bottom of the tub, its up r end extending above the normal water level in the tub. 'I'he 50 bottom wall ofthe tub rests on a ange 9 on the post 6 and islamped thereto by a nut I0 threaded on the post. When the nut' I0 is tightened the bottom of the tub is wedged within the skirt 3 against'the bead 2. thereby stiifening the upper Vend of the skirt.
The washing machine is driven by an electric motor II clamped at each end to supports I2 on brackets I3 which are secured to bosses I4 on one of the flanges 5c. The motor shaft I5 is connected through an intermediate shaft I6 and flexible couplings I'I to a worm shaft I8 journalled in the housing 5. The end thrust of the worm shaft I8 is taken by`a ball I 9, which is adjusted by means of a plug threaded into the housing. On the shaft I8 is a worm 2| which meshes with a worm wheel 22 keyed on a vertical shaft 23. The shaft 23 extends through and is joumalled in a tubular p'ost 24, the upper end of which (not shown) is adapted to support a wringer. The wringer post 24 is carried on the housing 5 by means of a sleeve 25 which is bolted to the top of the housing. On the lower end of the shaft 231s keyed a pulley 26 over which runs a belt 21 for driving a pulley 28 fixed on the lower end of shaft 29. The shaft 29 is journalled in the tubular post 6 by means of upper and lower sleeve bearings 30 and 3|.
- The shaft 29. projects above the upper end of the post 6 and the projecting Aend is fixed to the hub 33 of a sleeve 32 which depends around the post 6. The shaft 29 is supported by means of a thrust washer 32a arranged between the hub 33 and the upper end of the post 6. 'I'he lower end of the sleeve 32 is guided by a bearing 34 flxed on the post 6.
The washing action is effected by means of an agltatingmember 36 which is rotatably carried on the sleeve 32 by means of a pin 31 which extends through bearings in arms 38 and 39 projecting from the sleeve.. The agltating member, which may have any desired shape, is shown as a cylindrical roller. The agltating member 36 is. supported by a thrust washer 40 arranged between the arm 38 and a boss 4I on the agitating member. The lower end' of the agltating member lits over a bead or shoulder 42 on a disk 43 which is secured to the lower end of the sleeve 32. 'Ihe agitating member is eccentrically located with respect to the shaft 29 so that as the shaft 29 is rotated, the agitating member is moved orbitally about the shaft. 'This movement of theagitating member causes the clothes to be squeezed between it and the sides of the tub and also causes the clothes to have a relatively slow rotational or swirling movement around the tub in the same direction as the rotation of the clothes vertically along the agitating member. Since other clothes are drawn in to take the place of the clothes which are moved by the ribs,
the ribs are helpful in producing aturnover of the clothes which results in more uniform washing. Since the agitating member is free to turn, the friction between it and the clothes holds it relatively stationary during its orbital movement.
It is important that the friction in the mounting for the agitating member be kept at a minimum so that the agitating member-` can turn freely. This decreases the swirling of the liquid and clothes.
The disk 43 keeps the clothes from being drawn under the lower edges of the agitating member. This is partly due to the bead 42 which fits loosely inside of the agitating member and partly to the downward inclination of the disk which causes the clothes to slide radially outward away from the agitating member.
In order to increase the uniformity of the washing action two sets of vanes are provided projecting from the side walls of the tub. The lower vanes 4,5 are inclined upwardly from the bottom of the tub with respect to the direction of rotation of the shaft 29. 'I'he upper vanes 46 areinclined downwardly toward the bottom of the tub. In the operation of the machine the. clothes are given a rotational movement around the tub which is in the same direction as the rotation of the shaftl 29, although considerably slower. This rotational movement is assisted by the friction between the clothes and the continuously rotating disk 43. The vanes 45 and 46 utilize this `rotational movement of the clothes for the purpose of giving the clothes a roll-over movement which will continuously change the distribution of the clothes in the tub so that all parts of the clothes will be subjected to the washing action. The action of these vanes is shown 'diagrammatically in Fig. 5. As shown in this figure, the vanes 45 deilect the clothes upwardly from the bottom of the tub in the direction generally shown by arrows 41. There are also upward currents on the under side of the vanes 45 which carry the clothes upwards. These upwardly deected clothes strike against the under side of the vanes 46 and are deflected downwardly toward the bottom of the tub as shown by the arrows 46. The vanes 45 and 46, therefore, cause the clothes to be moved from one level to another level, producing a roll-over movement of the clothes which changes the distribution of the clothes in the tub so that uniform washing action is secured.A
the vanes 45 and against the lower surfaces of the vanes 46.
From another aspect, the vanes 46 have a combing action on the clothes preventing tangling or knotting. The mass of clothes on striking the leading ends of the vanes is deflected on either side. Slight tangling of the clothes is thereby straightened.
Figs. 6, 7, and 8 show constructions in which the vanes are formed integrally with the walls of a sheet metal tub. In the construction shown in Fig. 6, the lower vane is formed by a die which draws material inward from the side wall of the tub and upward from the bottom wall of the tub. There is sufcient material so that the metal can ow during the drawing operation to form the vane. When the vane is formed in this manner there is no undersurface, thus avoiding a reentrant portion beneath the vane which would bediiiicult to clean. From the standpoint of thefrom t e side walls ofthe tub. The lower surface 4 is substantially the sameas the lower surface of the vane 46. 'I'he upper surface 50 is inclined toward the side walls of the tub. The purpose of this inclination is to provide suilicient material so that the material can flow under the operation of the forming die. The inclined suring machine since it is a relatively inactive surface.
Fig. 8 shows another construction ,for forming the upper vane. In this construction the entire side wall of the tub above the lower surface 5I of the vane -is drawn inward by the forming die. This construction has the disadvantage that the rim of 'the tub is not circular but it is satisfactory from the washing standpoint. A
