ED ST ADAM SCHOTT, Oli` OAKLAND, CALIFORNIA.

CLGTHES-PUNDER.

T all whom t may concern:

lle it known that l, ADAM Sono'r'r, a citt zen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful improvements in Clotheslnounders; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to maire and use the same. y

This invention relates to washing machinos of the pounder or plunger type; and the object of the same is to produce a very simple clothes pounder made by preference entirely of sheet metal excepting the wooden handle, and by means of which the finest and most fragile fabric can be thoroughly cleansed in a few minutes time without rubbing and without the use of a wash board. This and other objects are carried out by constructing the machine in the manner hereinafter more fully described and claimed, and as shown in the drawings wherein- Figure l is a side elevation of this device complete. Fig. 2 is an enlarged vertical section through the head or lower end of the pounder constituting the washing' machine, and Figs. 3 and l are cross sections on the lines 3-3 and f--l of Fig. 2 respectively. Referring now more particularly to the attached drawings, the casing or body l of this machine is an upright cylindrical meinber or shell from whose upper end rises a domeor cone-shaped top 2 pierced at one side with an opening 3 closed by a screw cap d through which soap may be fed into the machine when the cap is removed. The body is by preference cylindrical, and disposed concentrically within it is the inner shell 5 which is also by preference a. cylindrical member shorter and of less diameter than the outer cylinders. rlhe upper end of the inner shell is closed by a horizontal partition 6 which is extended out to the angle 7 between the body l and top 2 and perforated as at 8 above the annular space 9 between the outer and inner members. Secured as by soldering upon the partition 6 at its center 10 is an upright tube 11 which passes through the apex of the cone 2 and is secured as by soldering at the point 12, and extends a little above said apex in a ferrule 13; and the wooden handle le is inserted through this ferrule and down the tube until it rests upon the partition 6, being se- Speclcation of Letters Patent.

cured therein by any suitable means such as a split pin la. Around said tube is an annular space of triangular cross .section into which access is had through the opening 3 when the cap d is removed, and this space communicates through the perforations 8 with the annular space 9 between the two cylinders, and also communicates through a number of rather large openings l5 with the interior space 1G within the inner shell 5.

The lower end of the inner shell is cut off ou a line l? somewhat above the lower end 1S of the outer shell or body l, and across said lower end of the inner shell are perforated straps 19 whose ends are extended outward and downward as at 20 and connected with the lower end or mouth of the outer shell or body l, there being several. of these straps suitably secured where they cross each other and where they cross the lower ends of the two shells and their functionobviously being to give rigidity to the shells and to hold them properly spaced so as to maintain the parts in proper relative position.

rlhe operation of this machine is as follows: rlhe clothing to be washed is placed in a tub and covered with water, and a little soap, preferably in the form of lump, is passed through the opening 3 and the screw cap put tightly in place. rlhe handle 14 being now inserted into the socket and fastened therein as by means of the split pin 1.4L', the operator grasps this handle and puts the head of this device into the tub, and then by reciprocating the handle vertically the clothing is washed by the pounding action of the plunger as it is brought down upon it. ln the descent of the device the large open mout-h. l? of the inner shell ad mits a considerable volume of water which, drives the air above it upward through the openings 15, then radially outward, and thence downward through the perforations 8 into the annular space 9 and out the lower end 18 of the outer shell so that it is ejected downward onto the clothes by the very act of pounding them with this machine. This air is saturated with water, and in its passage through the course outlined, the water takes up the soap which is in lumps and agitates it within the conical top 2, and therefore soapy spray is driven downward through. the perforations 8 and the space 9 and onto the clothes. @n a reverse movement due to the upward motion of the device, the volume of water within the interior 1G of the inner shell moves downward and therefore creates a partial vacuum within t-he top 2, with the result that the air within the annular space 9 is drawn upward more rapidly than the device is ascending and a certain amount of suction is created above the clothing. The result will be that the soapy water is sprayed onto the clothes at the very time that they are pounded by the machine, and is again sucked upward through and from the clothesI at the very time that pressure thereon is removed by the elevation of the device; and I have found by experiment that the most delicate and fragile fabrics can be washed by this machine in a short period of time and with a few vertical reciprocations of the instrument.

As above suggested, the parts are by preference entirely of sheet metal or other metal suitably treated to prevent rusting, and the connections are made by soldering or brazing excepting that the cap l should screw onto a nipple surrounding the opening 3. l do not wish to limit myself to the eXactmeans suggested for fastening the handle in place, and in fact such handle might be a permanent part of the device instead of being of wood and removable.

Vhat is claimed as new is:

The herein described clothes pounder comprising an outer cylindrical body, a conical top closing the upper end. thereof, a horizontal partition across the body on a line with its juncture with said top, the partition having perforations around its edge and larger openings near its center, an upright handle-tube fixedly mounted on said top, an inner shell concentric with and shorter than the cylindrical body and secured at its upper end to said partition inside the perforations through the latter so as to leave an annular space between the body and shell which is of less volume than the inner shell and crossing straps of perforated metal forming the bottom of the body and located a suitable distance from the lower edge thereof, said straps being uniformly separated7 whereby a suction chamber is formed below the bottom thus formed.

ln testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
