WASH BOILER ATTACHMENT Nov. 26, 1929.

Filed Nov. 8, 1928 ATTORNEY gYENTOR Patented Nov. 26 1929 JOSEPH GBISON, OF NEW YORK, N. Y.

WASHBOILEB n'rrnoniamrr Application filed November This invention relates to wash boiler attachments which enable the cleansing of clothes by the agitation caused by the internal circulation of a volume of water due to varying temperatures.

Heretofore, devices of this'type have not fully utilized the advantages of such a method of cleansing clothes, and also have not provided means for draining off sediment from the dirty clothing.

It is therefore an object of this invention to provide a wash boiler attachment by which the advantages of the convection method of cleansing clothes may be efficiently utilized.

A further object of the invention is to provide a wash boiler attachment in which sharp corners are eliminated so that the clothes may not be accidentally torn.

A further object is the provision of means to enable the draining d of sediment from the clothes, at the same time preventing the contact of the clothes with surfaces at very high temperatures, thus eliminating accidental burning or scorching.

These and other objects are attained by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawing, constituting a material part of this disclosure and in which Figure l is a plan view showing the device installed in a wash boiler.

Figure 2, is a side view of the structure shown in Figure l.

Figure 3, is a sectional view of a modified form of dome adapted to be used in the devic Referring to the drawings, the attachment is shown to be positioned in a wash boiler 5 of the common type. The attachment comprises a pair of similar domes 6 and 7 provided with semi-circular apertures 8 and 9, respectively at their free edges. Projecting from the domes 6 and 7 suitably sealed thereto, are tubes 10 and 11, in which are telescoped the legs 12 and 13 of a Ushaped tubular member 14. The tubes 10 and 11 are provided with a plurality of apertures 15, and the member 14. has similar apetu'e 16.

ing aperture-s through which the tubes 10 and 11 may pass is a plate 17 of considerable weight and preferably made of copper. This plate is also provided with a. plurality of perforations 18, and the plate serves to hold the attachment tightly down against the bottom of the wash boiler at the same time serving as a brace between the tubes 10 and 11. The device is further held rigid and down by a weighted bar 23 connected to the domes (S and 7 In operation, the'attachment is placed in a rash boiler which is filled with water and lire clothes tobe washed. The wash boiler is placed over a source of heat which soon raises the temperature of the lower layers of Water. The water within the domes, due to its con finement is heated to a higher temperature and partially converted into steam, which will rapidly force boiling water and steam through the apertures in tubes 10, 11, 14;, and discharge the same into and through the clothes, the discharge from tube 14 being effective upon the upper layer of clothes. The water, after having dissipated its heat, will fall by convection and again enter the domes 6 and 7 through the apertures 8 and 9, to be again superheated. The convection caused by the varying temperatures in the tion which agitates the clothes and facilitates the washing operation.

The U-member 14:, by telescopically engaging the tubes 10 and 11, enables the attachment to be adjusted for diiierentlevels of water. The perforations 18 in the plate 17 enable the sediment and other dirt to be drained into the lower part of the boiler so that it will not contact the clothes, at the same time the plate 17 prevents the clothes from engaging the bottom of the boiler which is at a high temperature, thus eliminating the danger of scorching.

In the modification shown in Figure 3, each dome is provided with a rib 20, which serves a guide for a band 2lhavinga groove 22 engaging therib 20. The dome and the band 2) are each provided with. a

tu I a l. the or of the constructed including many dome may be adjusted by sliding the band 21 on the rib 20.

By adjusting the areas of the apertures in the dome the rate at which the water enters the dome may be varied and consequently the action of the device may be regulated so that clothing being washed Will be violently disturbed or slowly agitated as may be desired. This feature is essential when washing certain types of fabrics such as delicate silks upon which a violent agitation may have a destructive effect. It will thus be seen that the modified form shown in Figure 3 provides a desirable means of regulating the action of the washing device in order to accommodate the characteristics of various textiles.

r'l -he for-egoing disclosure is to be regarded as descriptive and illustrative only, and not as res ictive or limitative of the invitation of which obviously an embodiment may be modifications without departing from the general scope herei indicated and denoted in the appended claims. Y I

Having thus described my invention, what 7 I claim as new and desire to secure by Letters Patent is :c

1. A wash boiler attachment, comprlsmg a pair of domes having apertures near their edges, perforated tubes extending upwardly from the domes, a tubular perforated member connecting the upper ends of the tubes, a rib on each dome adjacent the apertures therein, and an apertured grooved band slidable on the rib to adjust the area of the apertures to the dome.

2. In a wash boiler attachment, a domeshaped chamber having a plurality of apertures near its e099 a rib on the chamber ad-c jacent the aperture, an apertured band slidable on the rib so that the area of the apertures in the chamber may be varied.

{it A wash boiler attachment, comprising a pair of domes having apertures near their edges, perforated tubes, extending upwardly fromthe domes, a tubular perforated member connecting the upper ends of the tubes, a rib on each dome adjacent the apertures there-in, an apertured grooved band slidable on the rib to adjust the area of the apertures to the domes, and a heavy plate resting on the domes and provided with apertures for the passage of the tube, said plate having a plurality of perforations to enable the draining of sediment from clothes being Washed.

This specification signed this 5th day of November, 1928.
