WASHING MACHINE.

Application filed September 14, 1922. Serial No. 588,271.

To all whom it may concern:

Be it known that EDWIN Cownns, citizen of the United ,States, residing at Boston, in the county of Sufiolk and State of Massachusetts, has invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

, This invention relates to improvements in washing machines and more particularly to those of the small portable type.

One of the objects of the present invention is to provide a simple and practical washing machine which may be inexpensively manu fractured. v

A further object is to provide a compact, self-contained washing machine, which may be easily carried about and installed in a basin, bath tub, bucket or the like at a moments notice.

A. further object is to proyide a reliable and eficient washing machine adapted to be installed in a tub or the like which will eficiently operate upon the clothes to be washed by a peculiar circulation of the washing medium.

A further object is to provide a device of the last above mentioned character adapted to prevent the clothes or material being washed from checking the operation of the device and to prevent the clogging or matting of the clothes at any particular part of the receptacle in which they are being washed.

Other objects will be in part obvious and in part hereinafter pointed out. The invention accordingly consists in the features of construction, combination and arrangement of parts and in the unique relation of the members and of the relative proportioning and disposition thereof all as more completely hereinafter outlined. others skilled in the art to fully comprehend and understand the underlying features of this invention and in order that they may embody the same by numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed and made part of this disclosure, and in such drawings like letters of referenceindicate corresponding parts throughout all the views, in which Figure 1 is an elevational perspective view showing the device partly broken away To enable applied to a receptacle shown in section; an

Figure 2 is a plan View of the parts shown in Figure 1.

Referring in detail to this drawing, 5 indicates a portion of a tub or other suitable receptacle into which the washing machine forming the subject of the present invention is adapted to be placed. This machine comprises a triangular casing 6, of any desired length which may be conveniently immersed in the washing fluid. The upper part of this casing is provided with an arm 7 adapted to hook over the top of the tub and a set screw 8 forclamping the same firmly in place against the tub. This is perhaps the simplest form of attaching means and very desirable, for that reason, although it is, of course, to be understood that any desired means may be employed for temporarily holding the machine in place.

I preferably construct the casing 6 triangular in cross section, as shown in Figure 2, and the lower part is provided with an opening 10 screened to prevent the clothes from entering by any possible chance. Centrally disposed back of this opening is a nozzle 11 preferably projecting slightly beyond the face of the screen. This nozzle is connected to a discharge pipe 13as shown in Figure 2, provided at its upper ends with an elbow or other fitting 14t adapted to be connected by means of hose or tubing 15 to one side of a pump 16. The opposite side of the pump is connected by means of a pipe or hose 17 with an elbow or other fitting 18 communicating with suction pipe 20 which is open at its lower end. The pump 16 is adapted to be driven by any suitable source of power such as a motor 21 which may be connected with the usual electric light socket in the house or apartment where the device is used.

It is believed the construction, operation and method' of use of this device will be clear to those familiar with the subject. lit is sufficient to state that it is connected up in the manner substantially as shown in F igure 1, and the motor started, which in turn actuates the pump and causes the water to pass through the pipe 15 and out through the nozzle 11 under high pressure. This will cause the water to circulate in the manner indicated by the dotted lines, Figure 2, and

to carry the clothes or other material to be washed in a circulatory manner about the tub. It will be noted particularly that by having the receptacle 6 triangular in cross section there is no chance for the clothes to pack against the rear side of the device.

- The current of water or cleaning fluid will cause the .same to circulate past this inclined edge, thereby again subjecting the clothes to the strong penetrating and cleaning action of the jet issuing from the nozzle 11. Likewise this powerful jet will prevent clothes from blocking or matting against the screened or perforate suction opening lO arranged on the otherwise imperforate face of the receptacle 6, and through which the cleaning fluid is sucked by means of the pipe connections 17, 18 and 20 leading to the opposite side of the pump. After completing the Washing operation the device may be easily disassembled and stored away until it is desired to'be used again.

It will thus be seen that the present invention provides a simple and practical device which may be easily carried about and used when andwhere desired, as well as one whichis reliable and eflicient in use and op eration, without danger of in uring thev clothes to be washed while in use.

Without further analysis the foregoing will so fully reveal the gist of this invention that others may readily adapt it for various applications without omitting certain fea tures that from the standpoint of prior art fairly constitute .essential characteristics of the generic or specific aspects of this invention, and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims:
