ROLAND A. MCDQNALD, 0F ST. JOSEPH, MISSOURI.

WASHING-MACHINE.

T 0 all wiz-0m it may concern:

Be it known that I, ROLAND A. McDoNALD, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a machine which combines within itself a washing machine and extractor or Wringer and a rotary drying tumbler or drier, and more particularly, to a motor driven or manually driven drum or cylinder that is adapted to contain the clothes, which cylinder revolves within the primary cylinder, the primary cylinder being supported upon a suitable frame or support.

Another object of the invention is the construction of an eficient and simple auxiliary or rotatable cylinder that lis provided with doors held closed by springs, and which cylinder is divided by a partition, producing compartments in the cylinder.

Another object of the invention is the construction of a washing machine that can be heated for heating ythe water in the machine or the heating means utilized, when desired, for drying the clothes in the machine, while they are being tumbled about by the motion of the machine.

IVith these and otherobjects in view, my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out Ain the appended claims.

In the drawings:

Figure 1 is an end view, in elevation, of a machine constructed in accordance with the present invention, -while Fig. 2 is a side view of the same.

Fig. 3 is a sectional view, taken von line 3-3, Fig. 4, and looking in the direction of the arrows.

Fig. 4 is a sectional view, taken on line 4 4, Fig. 3, and looking in the direction of the arrows.

Fig. 5 is an enlarged perspective view of the auxiliary cylinder.

Fig. 6 is an enlarged fragmentary sectional view of the auxiliary cylinder.

Fig. 7 is a sectional view, taken on line 7-7, Fig. 5.

-Speccation of Letters Patent. Patented Dec,

Application led May 29, 1920. Serial No. 385,164.

I Referring to the drawings by numerals, 1 designates a suitable platform,t0 which is secured the frame 2 of the machine; the

frame 2 is preferably made of metal, and

upon its upper end is supported the primary cylinder 3; the cylinder 3 has an opening 4, closed by the hinged door 5.

Heatingmeans, such as a gas jet 6, is placed under the primary cylinder 3, whereby said cylinder may be heated for heating water contained therein, or when water has been emptied from the cylinder, by means of faucet 7', the heat generated from thejet 6 may be utilized to dry the clothesthat may -le contained in the revoluble auxiliary cylin- The auxiliary cylinder is preferably perforated (Figs. 3 and 4) and in the cylinder is a perforated partition 8, dividing the cylinder into two compartments. Extending through the cylinder 7 and partition 8 is a shaft 9; this shaft is journaled upon ball-bearings 10, and to one end of the shaft, outside of the primary cylinder 3, is suitably -attached a crank handle 11, and to the other efliciently in place upon the auxiliary cylinder. A pair of inwardly-swinging doors 17 are hinged at 18 upon the auxiliary cylinder,

and the resilient or springy bands extendv through integral eyelets 19, projecting from the outer face of the doors,thereby permitting vthe doors to be pressed inwardly to c allow the insertion or the removal of clothes from the compartments of the auxiliary cylinder, but upon the operator removing pressure from 'the doors 17, they will immediatelybe closed by the action of the bands or wires 16, and any suitable latch device or catch may be used, at 20, for holding the doors 17 normally in their closed position.

I found from experience that the dividing -of the auxiliary cylinder into sections or compartments produces a better balance of the load as the machine washes, wrings and dries and enables the cylinder 7vto be rotated in one direction without tangling the clothes; I lclaim this to be a new principle in this type of a one-way washing machine.

My machine is what may be called a three-in-one machine; that is, it is a washer, extractor or wringer and drier. It does the work of a wringer and wrings by centrifugal'force without the assistancev of heat or any other agency. It is a drier when the heat is applied to the machine after they process of wringing or extracting has been completed.

In operating my machine, it will be necessary to run the same at one speed for washing clothes, and at another for extracting, and yet at another for drying.

It will be appreciated that my machine may be adapted for use in a laundry or for use in a dwelling or home. Further, while I have described the preferred embodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a washing machine, the combination with a frame, a primary cylindercarried by saidl frame, of an auxiliary cylinder mounted within said primary cylinder, a partition in said auxiliary cylinder, a hinged door carried by said auxiliary cylinder, and springs means extending through a part of lsaid partition and'through a part of said door for normally holding the door in a closed position upon the auxiliary cylinder. 2. In a washing machine, the combination with a frame, a primary cylinder upon said frame, of an auxiliary cylinder in said primary cylinder, a partition in said auxiliary cylinder and having portions of its ends extending through the auxiliary cylinder, in-

wardly-swinging doors on the auxiliary cylinder at opposite sides of the partition, and resilient bands positioned in the ex-tended ends of the partition and fastened to the doors for moving the same to a closed position after they have been swung inwardly tured lugs of the partition and Vthrough the eyelets of the doors ,for causing the doors to swing outwardly to a closed position after said doors are pressed inwardly for the placing of or removing of clothes from within the auxiliary cylinder'.

In testimony whereof I hereunto afiix my signature.

ROLAND A. MCDONALD.
