Millers Falls No.5 eggbeater drill; second example of Type 6.
The first official No.5 model, this type has a newly designed frame with a machined spindle housing and a separate axle for the idler pinion, a much more efficient design than the iron-framed No.3 Type 4.  The rosewood main handle has a narrow flare.  The only markings are the patent date and company name on the no-springs, 3-jaw chuck; the tapered crank is unmarked.   Note the pronounced triangular shape of the pinion teeth, indicative of the larger than usual pressure angle used to strength the pinion teeth.  This change was made possibly because of the use of the idler pinion to counter the tendency of the main gear to deflect away from the drive pinion. This example has a side handle that appears only in one hardware catalog - that of Montgomery & Co., New York, ca. 1897.
