Abstract
A portable mixing device particularly for use with power drills or the like, having a helicoidal flight of coil units of equal dimensions leading up from a bottom, that has a radial edge to scrape material off the bottom of a can and a rounded corner that prevents the edge from cutting into a can, the several coils of helixes terminating at the top in another radial edge with a rounded corner to prevent cutting into the side of the can, with a circular baffle plate spaced a predetermined distance above the top edge of the helical flight to deflect the material being stirred upwardly by the device, outwardly to that it can then circulate back downwardly to effect the mixing circulation.
Claims6
A mixer having a center shaft adapted to be vertically disposed in a receptacle of material to be mixed, a helicoidal flight of a plurality of coil units arranged about and extending outwardly from the center shaft, the lowermost coil unit at the bottom of the device having a substantially radial edge that extends outwardly from the shaft and that is horizontal, and having an outer corner rounded so as to reduce a tendency to cut into the receptacle, the upper end of the flight having a terminal edge that extends outwardly from the shaft and is substantially radial and with its outer corner rounded to avoid cutting into the receptacle, a baffle disk centered on the shaft and spaced above the upper terminal edge of the flight, the baffle disk and the flights providing an opening above the flight toward which the flight can direct the material being stirred and the baffle disk being adapted to deflect the said material outwardly from the shaft.
