Millers Falls No.2 Eggbeater Drill Type Study

Type K3

The Type K3 is the third of the LRRCW models. It now 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 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 Millers Falls chuck that had an exceedingly short production life.  This chuck carries no patent date but has reeding which usually ifferentiates early Millers Falls three-jaw chucks from later ones.  See my Millers Falls Types 1, 2 & 3 Type Study.  See also Type K4, whose "PAT APPLIED FOR" chuck (later patented September 20, 1890) is also reeded.  The Type K3's chuck is not the only example of this unpatented chuck type that I have seen.  I have another, very decrepit Type K3 whose remaining chuck base has the same shape as the present one.  It could very well be that this chuck was built just like the Goodell-Pratt chucks patented in 1895, a practice towards which the Goodell-Pratt Company might have directed some animosity.    See US Patent No. 544,411, August 13, 1895, granted to Herbert D. Lanfair.  Mebbe that's why the LRRCW never got patented (too closely resembles the wiper of the Lanfair patent) !  The malleable-iron frame of the Type K3 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.  Recovered in the same MJD auction lot as the Type K1; thanks, Martin.  The crank and its handle appear original and carry no identification markings.  Only the chuck carries the "Millers Falls Co." name; this chuck has lost its three internal springs, unfortunately.  This drill is otherwise in amazingly good condition for a 125-year-old tool.  The red and black paint job is original, and there is next to no loss of nickel plating which covers all parts, even underneath the paint of the main gear and frame.  Only the pinion, LRRCW mechanism and spindle are uncoated steel.  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.
