Millers Falls No.2 Eggbeater Drill Type Study

Type K4

The Type K4 is the fourth of the LRRCW models. It also has provision for a side handle, which has been lost in antiquity from this example but which was probably egg-shaped like that on the Type J. The thrust bearing is still a simple cylinder adjustable from between the spokes of the main gear wheel in order to control the end play in the spindle. The adjusting screw can barely be seen peeking out from behind a spoke in the image at far left.  The main rosewood handle is in its slimmest form, but there is as yet no "breast pad" to aid in pushing on the handle, even though the 1877 patent two-jaw chuck has now been replaced with a larger, 1/4 inch  capacity three-jaw springless Millers Falls chuck marked "PAT APPLIED FOR" (later patented September 20, 1890) that is reeded like other early Millers Falls chucks.  See my Millers Falls Types 1, 2 & 3 Type Study.   The malleable-iron frame of the Type K4 is the wider version of the new model, but with the central boss redesigned to accommodate the tapped hole for the side handle's stud.  The crank and its handle appear original and carry no identification markings.  Only the chuck carries the "Millers Falls Co." name.  This drill is in good condition for a 125-year-old tool.  The very slim neck of the main handle remains strong because the straight tubular brass ferrule did not succumb to season cracking as do nearly all the later, deep-drawn ferrules of the No.2 Milllers Falls drills, which ought to have been stress relieved but weren't.
