TRANSACTIONS OF THE 



Barlow's Rotary Wood-Planing Machine. 



JVo. 842 — Rotary Wood Plaimig Machine. 

 Alfred Conger, 345 Broadway, "Earlow's Patent." The best, very 

 compact and works well, \A silver medal awarded. 



JYo. 1521 — Improved Circular Saw and sharpener for Sato Teeth. 

 N. Barlow, 345 Broadway. Excellent, the principle is to form 

 each tooth into a very small gouge by means of a small nut or 

 cutter, which is readily placed in front of the tooth, and the in- 

 strument then clamped against the side of the saw by means of 

 a circular cam; then by means of a crank the cutter is turned 

 while held against the front of the tooth. The cutter is so formed 

 as to cut only at the bottom while it spreads the metal outside 

 so as to give a set on both sides. This saw makes a very clean 

 cut, being a new idea, with more real ingenuity than most inven- 

 tions; we put it in the medium grade of premiums, although a 

 very small thing in point of size. \^Ji silver medal awarded.
