Falls No.1, 3 & 5 eggbeater drills
to Main Page
No.5 eggbeater drill; second example of Type 16.
Millers Falls logo and model number are stamped on either side of the crank
affixing screw, along with some lines, that perhaps were used to as a substitute
for a lock washer, near the crank knob. The protected-spring, 3-jaw
chuck is no longer stamped with the patent date; and the thickly red lacquered
hardwood main handle has a gently rounded flare.
The major change
is in the frame, which is now made of die-cast alloy. The pinions
have a more usual pressure angle.
