JVo. 258 — Felloe Dressing Machine.

[Ji diploma awarded. 



JVo. 297 — Machine for Turning and Boring Wood. 

 A. & r. Brown, 395 Fifth street. The best. Excellent, self-acting, 

 simple, eflacient, expeditious. If this instrument were the con- 

 trivance of the present date, it would deserve the highest pre- 

 mium as an admirable production, but since these tools had 

 already been brought to a high state of usefulness, we report this 

 as the second degree for the finishing improvement, making it, 

 as appears, all that is attainable in this direction. 



[A silver medal awarded. 



JYo. 4:8(5—Saw Mill Feeder. 

 C. M. Day, 45 Avenue D. The best. By means of a rack and 

 pinion the connecting rod is placed at any position on the lever 

 that gives motion to two opposite cams which seizing the wheel 

 on the two sides hold by friction and cause it to revolve.

JVo. 656 — Power Mortising Machine. 

 Lane k Bodley, Cincinnati, Ohio. Is the best; excellent for heavy 

 or light work; relieving the foot from jar by means of a toggle 

 joint which brings the chisel into action. Reversing the chisel 

 by a stationary spring lever while the chisel is in motion, or at 

 rest, as the case may be. [A silver medal awarded. 



JVo. 1589 — Power Mortising Machine. 

 J. A. Fay k Co., Keene, N. H. The 2d best. This machine has a 

 pulley attached to a crank wheel that gives a continuous reci- 

 procating motion to the chisel; the whole of this work is drawn 

 down by a foot lever, and consequently the entire resistance 

 comes from the foot. This for heavy work would produce a jar 

 at least unpleasant, that is not felt in No. . The inventor 



claims an improvement in the self-reversing of the chisel. This 

 is produced by a catch, acting on a half cylindrical inclined plane.
