WASHING-MACHINE DOLLY.

- Application filed larch B8, 1928. Serial No. 627,009.

My invention-relates to that class of devices used in washing machines for the agitation of the clothes in the washing machine tub, the same being ordinarily referred to as dollies, and amongthe objects of my invention are to provide a buoyant dolly composed of material of greater specific gravity than the liquid in the tub in which t rates, together with means for oscillata ly mounting the dolly in a washing ma chine so that the dolly is free to float in the liquid as it oscillates; to provide' an oscillatable dolly composed of material heavier than water which is constructed and arranged to float as it oscillates in the liquid; to provide a durable and effective washing machine dolly; to provide an all metal dolly which will not work its way through the clothes and rub on the bottom of the tub; to.

provide an all metal dolly which will float in the water in the washing machine tub; to provide a floating all metal dolly which is simple in construction, easy to manufacture and not liable to get out of order; and such further objects, advantages, and capabilities as'will later more fully appear.

' My inventionfurther resides in the combination, construction and arrangement of parts illustrated in the accompanymg drawing, and, while I have shown therein a pre-' ferred embodiment, I desire the same. to be understood as illustrative only and not as limiting. said invention.

In the drawing annexed hereto and forming apart hereof, Fig. -1 is a plan view illustrating my invention with parts thereof broken away, and Fig. 2 is a vertical substantially central section of the construction" shown in Fig. 1. Fig. 3 is a perspective view of a washing machine taken with the lid open and the bottom of the dolly exposed to view. Referrin more in detail to this drawing, numeral 1 esignates the body proper of the dolly, 2 the float secured thereto, 3 the wings or liquid impelling members of any desired design and arrangement and,

refer-ably inte ally connected with the Body 1, and 4 e shaft whereby the dolly is operated. well known to those skilled in the art the square shaft 4 depends into the tub T through a similarly shaped aperture in an oscillatable gear 4 mounted on top of the tub. The shaft, while thus actuated by the gear, is free to rise and fall therethrou h so that the dolly can accommodate its f to variations in the level of the liquid in the tub and to the amount of clothes or other fabrics therein. The upper face of the body 1 is provided with a socket 5 shaped internally to fit the end of the operating shaft 4 and secured thereto by a suitable means such as a rivet 6. In the preferred embodiment of my invention, the float 2 is' a hollow all-metal waterproof can having lugs 7 secured in spaced relation inside. of the same, as shown in Fig. 1. These lugs 7 are soldered or brazed to the inner face of one side of the can as shown in Fig. 2,

and holes are drilled and tapped through the wall of the can or container into the lugs for the reception of screws 8 which fasten the body member 1 and the float 2 together.

It is importantthat there shall be no holes through the wall of the float member 2 whereby water or air may have exit or entrance to the interior thereof; In this way it will be possible to prevent any water gaining admission to theinterior cf the'float, thereby causing the same to become heavy and no longer capable of functioning as designed. Furthermore, if water gains access to the interior of the float, there will be a tendency for rusting to take place and the float would be eventually destroyed as a result. It will be seen from Fig. 2 that all of the force transmitted to the dolly shaft 4 is transmitted thereby to the body 1 and that, therefore, no strainis put upon the float 2, the sole function of which is to prevent the dolly from sinking through the mass of clothing to the bottom of the tub and rubbing thereon. It is therefore obvious that I have produced a durable, effective, floating, washing machine dolly which is easily manufactured and installed and is not liable to get out of order. clear that, while I prefer to use metal for It is also the entire construction, other heavy maporting said dolly within the tub, said means being constructed and arranged to permit the free vertical movement of said dolly in the tub and said dolly being composed of material of greater specific gravity than the liquid in the tub, and rendered buoyant by structural characteristics of said dolly.

2. In combination with the tub of a Washing machine adapted to contain a Washing liquid, a dolly composed of material of greater specific gravity than the liquid, means for oscillatably supporting said dolly within the tub, said means being constructed and arranged to permit the free vertical movement of said dolly in the tub, and said dolly being provided with a float to cause said dolly to float in the liquid.

3. A dolly comprising a metal dolly provided with liquid impclling means and having a metal float attached thereto.

4. A Washing machine dolly comprising a metal body provided with downwardly ex; tending liquid impelling means and a detachably connected metal float.

5. A metal dolly comprising a metal body and a float, the body having liquid impelling means projecting therefrom and the float being detaehably connected to the body.

6. In a Washing machine dolly, a metallic body portion having integral downwardly extending liquid impelling means and an integral upwardly extending centrally arranged boss, an operating shaft connected thereto, and a float secured to the body portion and adapted to maintain the dolly floating in the water.

7. An all-metal dolly of the character described, comprising a body part and a float member secured thereto, the body part having liquid impelling means extending from one face thereof and a centrally arranged boss extending from the opposite face thereof, and a centrally apertured float member secured to the body, member and surrounding the boss.

8. An all-metal washing machine dolly comprising a body portion having liquid impelling means projecting from one face' thereof and a centrally arranged boss projecting from the opposite face thereof and a hollow centrally apertured metal float member secured to the body member, With the boss extending into the central aperture, the interior of the hollow float being devoid of open connection with the surrounding atmosphere.

In witness whereof, I hereunto subscribe my name to this specification.
