Chuck noticed
a similarity of outline between his drill and a patent granted to
Jonathan Hammond on October 11, 1875, below (edited for this
format). The details of the attachment of the pinion gear to the
spindle do not correspond, but the patterns of the frames are
similar. Note that Hammond was granted his patent only three
years before the Millers Falls No.1 first appeared in an 1878 Millers
Falls catalog, so Hammond may have borrowed the frame outline from the
drill shown above. It appears to Chuck that Art DeKalb's drill is
a skillfully executed repair of a broken example of the present drill;
their gears & frames closely match. To both Chuck and me this
drill is a precursor to the line of drills manufactured and effectively
marketed by the Millers Falls Company, as either the No.1 or the No.4
"jeweler's" drill. There is an image of an eggbeater drill
on Chuck's website whose frame closely resembles the drill shown
here. |
There's more to this story, including an interesting patternmaker's copy of the Type 1 or 2 Millers Falls No.3 that improves the idler pinion mechanism, on Chuck's website. |
