TUENGST AND OSCAR 1L ANDERSON, NEW BRITAIN, CONNECTICUT, AS- SIGNORS 1'0 LANDERS, FBABY & CLARK, OF NEW BRITAIN, CONNECTICUT, A COB- PORA'I'ION OF CONNECTICUT WASHING MACHINE Application filed September 6, 1927, Serial No. 217,579. Renewed Kay 8, 1980.

This invention relates to machines for washing clothes and the like of the type having a stationary tub and an oscillatory dolly provided with a plurality of fins or baffles.

Q The invention has particular reference to an improved dolly.

The general aim of the invention is to provide an improved construction wherein clothes or other articles may be quickly and loefi'ectively washed and cleansed without injury thereto.

More particularly, the aim of the invention is to provide a washing machine with an improved dolly which gives the water and the clothes immersed therein a constant rolling effect or motion which produces the best results and hastens the cleansing without danger of injuring the clothes, even the most fragile and soft materials; which sets up a free agitation and directs the currents in such manner as to cause the fluid to penetrate the clothes and thoroughly cleanse them; and which prevents snarling, tangling or bunching up of the clothes and all possibility of the clothes wrapping themselves about the dolly, it having been found that tapes, strings and the like may be put in among the clothes without any tendency of these string-like articles clinging or coiling themselves about the dolly.

We have found from extensive tests that our improved dolly eliminates many disadvantages and objections incident to machines of this type which are now on the market.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawings, wherein is shown, for illustrative purposes, one of the many embodiments which the present invention may take, it being understood that this disclosure is by way of exemplification only:

1 Figure 1 is a side elevation of the improved dolly;

Fig. 2 is a planview thereof;

Fig. 3 is a vertical sectional view through the dolly and the mounting therefor; and

Fig. 4 is a sectional view through one of the ins, this view being taken on line 44 of Referring to the drawings in detail, the numeral 10 designates a tub of suitable size and shape. It is preferably round and has its upper edge extending above the top of the dolly. The tub may be supported on a base 11. Arising centrally of the tub and preferably to a pointabove the waterline, (designated by the line a2:z2) is a tubular support or sleeve 12 in which is journalled a shaft 13 adapted to be oscillated about a vertical axis in any suitable manner, the mechanism for oscillating the shaft and the dolly connected thereto not being illustrated as it may be of any suitable construction. Secured to the upper end of the shaft 13 is a polygonal, for instance a square, bushing 14 adapted to be received by a similarly shaped hole 22 in the top of the dolly so that, when the dolly is in position, the shaft and the dolly will oscillate in unison. At the lower end of the support 12 is a flange 15, the upper surface of which may form a bearing for the spider 23 mounted in the lower end of the dolly. The construction so far described is shown for illustrative purposes only and may be changed.

Reference will now be had to our improved dolly wherein the gist of the present invention resides. In the present illustrative disclosure, this dolly has a disk-like plate or base 20 and a generally cylindrical standard or stem 21 arising centrally thereof. The upper end 21' of the standard is generally tapered or dome shaped, thus making it more or less rounded so as to avoid sharp corners or angles. By preference, the standard is of susbtantial diameter, in the present instance, the diameter of the standard being only slightly less than the radius of the base 20. The upper end of the standard has a square hole 22 adapted toclosely receive a bushing 14 on the upper end of the drive shaft. 1 Suitably secured in the lower end of the dolly and resting upon the flange 15 is a spider 23.

The'dolly has a plurality of agitating fins A, preferably three in number and equally spaced apart, and these fins are of particular construction in order to obtain the best result in operation. Each of the fins extends generally radially of the dolly and has a body portion which is inclined upwardly from the outer edge of the base toward the standard. The body portion of each fin has inwardly curved or concave side walls 25 which diverge as they progress toward the standard. Thus the body portion of each fin increases in width from its outer edge 26 toward the standard and tapers down in width from its lower end to its upper end. The upper ends of the fins merge into the standard at a point spaced a substantial distance from the top of the standard, in the present instance these fins being about two-thirds of the height of the standard and merging into the standard ad 'acent the lower end of its tapered portion 21. Each fin has extending from the lower portion of the outer edge of its body portion a flat lobe 27 which preferably extends beyond the edge of the base. The upper edges 28 of the lobes gradually merge into the respective outer edges of the body portion of the fins.

The lower ends of the side walls of the fins are susbtantially tangential to the standard, as will be most clearly seen in Fig. 2. The upper end of the standard may be provided with 2. ca 30 having a threaded stud 31.

With t e arrangement described, when the dolly is oscillated, the-water, together with the clothes carried thereby is caused to travel generally outwardly of the dolly at the bottom of the tub, then upwardly alongthe side of the tub, then inwardly towards the dolly, and then downwardly of the dolly so that substantially continuous currents are set up which are so directed that the clothes are caused to travel with more or less of a rolling motion. Owing to the peculiar shape of the fins, the water has more or less of a sweeping action as it passes over the sides of the fins. The relatively fiat vertical lobes accelerate the radial movement of the water at the bottom of the tub. It will be observed that the dolly is substantially devoid of ockets or dead spots in which the clothes mlght bunch up or collect or in which a free and complete agitation of the water may not be had. From actual use of the apparatus, it has been found that the circulation of the water is relatively rapid and is such as to maintain the clothes in a more or less spread out condition, insuring that the water may be caused to penetrate all portions of the clothes and efi'ect cleaning to the best advantage. The clothes do not tend to cling, collect or wrap themselves about the dolly. In the event that a blanket or other large article should be placed or find its way over the top of the standard, it would be gradually and gently withdrawn therefrom and put into circulation without any danger of the article wrapping itself about the dolly or becoming torn or otherwise damaged.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be inter preted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
