' a bath basin.
The invention is fully disclosed in the description and claims following, reference being had to the accompanying drawing, in which Figure 1 is a side elevation of a dasher embodying my improvements. Fig. 2 is a central, vertical section of the same, with a shortened handle. Fig. 3 is a plan View of the same below the section line 3-3. Fig. 4 shows in perspective the upper end of the tubular handle and the mounting of the valve 7 therein.
To a tubular handle 5 is attached a heater or dasher 6. This is hollow and bell-mouthed, terminating at the mouth in an annular flange 7 pierced with holes 8, and headed at the rim 9. Above this the bell is provided with a series of annular corrugations 10. At the upper end the handle has a cap 11 provided with an air inlet 12, and terminates in a ring 13 for convenience in hanging up the article, and serving also to prevent the operator from closing the air inlet inadvertently with her hand. A valve-seat 14 surrounds the airinlet, and below this is mounted a valve 15 normally resting on tangs 16 slit from the tube and turned inwardly, as clearly shown in Fig. 4.
The device is operated by pressing the bell down on the material immersed in soapy water with more or less force. The principle of cleansing is that of forcing air and water through the fabric and thus detaching the Serial No. 264,370.
dirt, no scrubbing or even vigorous pounding being necessary. It will be evident that as the bell is forced down upon the immersed materials the air within is trapped, and with added pressure is compressed to some extent. Being so compressed it seeks an outlet by the path of least resistance. This may in part be directly through the mass of material, which is of course desirable, but more or less of the air will naturally follow the internal wall of the bell. Because of this, it is found in practice desirable to break up the smoothness of the bells interior with a series of annular corrugations, which give the arresting effect of bafiles, tending to deflect the air, and send it diagonally through the fabric instead of escaping along the wall and out at the extreme edge of the mouth. The result is therefore to give a more uniform distribution of air through the mass, with a correspondingly better cleansing effect.
The purpose of the perforations along the edge of the bell is partly to limit splash, and more especially to promote the formation of suds. The forcing of soapy water upwardly through these holes serves to form suds very rapidly.
The valve at the upper end of the handle is of an improved type, being cupped below, as shown. Its supporting tangs are inclined upwardly, and in the upstroke of the dasher, when acted upon by suction and gravity, the valve drops centrally on the supporting tangs, leaving a clear and practically uniform annular space around it for the intake of air. This free and unobstructed flow of air in a ring makes for ease and e-fliciency in operation.
I claim:
1. A laundry dasher, comprising a tubular handle, an air-valve to close its upper end, and a bell at the lower end corrugated to form a series of annular baflles, and having an outer substantially horizontal, annular flange with a down-turned substantially cylindrical rim and perforated through said horizontal annular flange for upflowing jets of Water.
2. A laundry dasher, comprising a tubular handle with a bell at its lower end, and at its upper end having inturned tangs upwardly inclined formed by clipping and bending inwardly segments of the tubular handle, a cupped Valve mounted to normally rest on said tangs, and an inlet cap attached to the upper end of the handle, having a Valve-seat formed around the air inlet, and an annular flange enclosing the cuts in the handle.
In testimony whereof I aflix my signature. LEO M. STALKER.
