The Gear

It is a very handsome design, with proportional width of the rim and slender spokes.  The spoke that will hold the crank handle is a bit thicker on the bottom and on the face side it has a mounting bracket.

One distinguishing feature on this gear is a hook on the handle mounting bracket.  It helps to leverage the force applied to the crank handle when gear is turning as well as relive some pressure from the screw holding the handle on the gear.  This hook disappeared with 1910 release of the next model.

Good looking gear with a handle.

The Chuck

I have discussed the construction of this chuck in another section, so we will only briefly look at it here.  It is based on design and patent by William H. McCoy.  The patent was issued on September 29, 1896 with number 568,539.  The patent's production rights were assigned to Millers Falls Company.

It is spring-lees chuck with three jaws capable of holding bits from 0 to 17/64 inch.  This chuck was very popular and was used on many Millers Falls Drills, from No. 1 drill to No. 7.

The shell of the chuck has patent information stamped on the smooth bend.  The base of the chuck holds jaws in machined grooves.

It is a simple and effective construction.
