GEORGE B. PILLAR,A OF MILWAUKEE-WISCONSIN.

WASHING MACHINE.

Application med September To aZZ whomtmay concern.'

Be it known that I, GEORGE B. PILLAR, a citizen of the United States, and residentof Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Washing Machines;`and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to washing machines of the type in which the clothes to be washed are placed in a rotary perforated drum thru which there is a continuous circulation of the cleansing fluid while the drum is rotated.

It is customary durin the process of cleansing the clothes to sub]ect them to treatment by a number of different solutions successively, such, for example, as a soapy solution, then a rinsing water and finally a bluin solution.

lcne of the principal objects o f the present invention is to provide a'machine in .which there are a plurality of receptacles which are linitially provided with the respective liquids which are to be used and in which the clothes may be successively subjected to the action of the different liquids, each liquid after assing thru the clothes in the rotating drum ing returned to the receptacle from which it is taken.

It is also an obj ect of the invention to provide a machine of this character with means whereby the liquid may be completely shut ofi' between the periods of treatment while the drum continues to rotate for the purpose of removing the excess moisture from the clothes and allowing it to drain back into the receptacle.

The invention consists further incertain structural details and combinations of parts which will be more specifically described hereinafter in connection with the accompanying drawings and subsequently claimed.

In the drawings,

Figure 1 represents a vertical sectional view thru the central part of the machine, as indicated by the line 1--1 of Figure 2.

Figure 2 is a plan view of the invention.

Fi ure 3 is a sectional plan view taken on the line 3-3 of Figure 1.

Figure 4 is a detail view of the valve adjusting mechanism.

Fi ure 5 is a detail view showing the relation etween the pump and the valve box.

Figures 6, 7 and 8 are diagrammatic views showing the valve in different positions, and

the adustment of the drain spout in connection t erewith.

Referring now to the drawings in detail. the numeral 1 represents the frame structure on which are supported a plurality of liquid receptacles 2, 3 and 4.' These receptacles are preferably arranged in the manner shown about the center of the machine, and a central bearing block 5 supported upon the frame structure rotatably supports a vertical shaft 6 which carries at its upper end, a perforated drum 7 for receiving the clothes. AThis drum is rovided centrally with an u wardly exten mg sleeve thru the upper en of which is secured a pin 9 which is lreceived in the bifurcated upper end of the shaft 6 to support the drum. A disk 10 is secured to the shaft 6 near its lower end .and is provided with downwardly projecting pins 11 which are received between the spokes of a wheel 12 and driven thereby.

The wheel 12 is ournalled concentric with the shaft 6 and is provided with a. bevel friction face which is engaged by the bevel friction gear 13, which is secured to the shaft 14 of the motor 15. The gear 12 is held in enagement with the gear 13 by a suitable ro er bearing 16.

The motor shaft 14 also has a driving connection 17 with a shaft 18 which operates a ump 19 by means of which the cleansing iquid is pum ed upwardly thru the pipe 20, and projecte over the clothes contained in the drum by a suitable spray head- 21. The liquid is drawn by the pump thru the pipe 22 from the Valve box 23, thru which connection is made with either of the pi es 24, 25 or 26 by means of a rotary va ve 27. The pipes 24, 25 and 26 are connected with the receptacles 2, 3 and 4 respectively, and the valve 27 is mounted on a'rotary shaft 28 which is ad'ustable by means of a hand wheel 29 to p ace the pump selectively in communication with either of the receptacles desired.

When the valve has been suitably adjusted and the motor 15 started, the drum 7 is rotated while the liquid is continuously pumped up thru the pipe 20 and sprayed over the clothes. This liquid, as it percolates thru the clothes, drains out thru the perforations in the drum 7 and collects in the circular trough 30 which is supported beneath the drum. The sides of the trough are extended upwardly, as shown at 31, to surround. the drum and catch the liquid p which is thrown outwardly by centrifugal action. The top of the trough is closed by a cover 32 which also encloses the drum. The liquid from the trough 30 drains thru the outlet 33 into a spout 34 which is connected therewith by a suitable union 35. This spout 34 is angularl adjustable about the opening 33 so as to eliver into the re'- ceptacle 2, as shown in Figure 3, or into the extension spout 36 which delivers to the receptacle 3 or into the extension spout 37 which delivers into the receptacle 4. The adjustment of the spout 34 is efected automatically whenever the valve 27 is adjusted so' that the liquid draining from the drum 7 is returned to the receptacle from which it is drawn.

The connection between the valve 27 and the spout 34, by means of which the latter is automatically adjusted in coordination with the former, com rises a cam 38 which is secured to the va ve'shaft 28 and provided with a pair of pins 39 and 40, as shown in Figure 3. The successive adjustments of the valve and the correspondlng locations of the pins 39 and 40 are illustrated in Figures 6, 7 and 8. The spout, as shown, is provided with a lateral rib4l and a finger 42, which are engaged successively by the pins 39 and 40 to adjust the spout. As shown in Figure 6, the water is being drawn thru the pipe 24 from the receptacle 2, and the spout 34 is in position to deliver back into the receptacle 2. When the shaft 28, which carries the valve 27 at its lower end, is rotated to open the pipe 25 to the action of the pump so as to draw the liquid from the receptacle 3, the pin 29 engages the rib 41 .and moves-.the spout to the position shown in Figure 7 so that it delivers to the spout 36, which, in turn, delivers to the receptacle y3 Upon further rotation-of the shaft 28 and valve 27, the pump is ;placed in communication with the pipe 26 and receptacle 4, as shown in Figure 8. In this position the pin 40 has engaged the rib 41 and swung the spout 34 still further so that it delivers to the spout 37 and thence back to the receptacle 4. When the shaft 28 and valve 27 are rotated still further in the same direction until they again reach the position shown in Figure 6, the pin 40 engages the finger 42.

and swings the spout34 back into the position shown in Figures 3 and 6.

From the above description, it will be Seen that the liquid may be-drawn from any of the three receptacles and will always be returned to the receptacle from which it is drawn. The valve 27 also has an .intermediate position between each of the active positions' wherein the pump is shut olf from all of the receptacles. This is for the purpose of permitting the drum to rotate withoutl receiving any liquid so that the centrifugal action thereof will drain all superfluous moisture from the clothes before they are subjected to treatment by the next liquid.

It will also be observed that in order to bring about the desired coordination between the spout 34 and the valve, it is essential that the shaft 28 should always be rotated in the same direction. A ratchet 43, shown in Figure 4, is therefore provided to act in cooperation with the hub of the hand wheel 29, so as to revent the operator' from making a mista e adjustment.

While I have shown my invention as applied to a washing machine in which three dilerent solutions are designed to be used, it is, of course, apparent that the structure may be modified so as to be used in connection with any number of receptacles.

It will also be understood that various other modifications may be made in the minor structural details without de artin from the spirit of the invention as 'claime I claim:
