above the bed, one on each side, and two feed rollers, one fluted 

 and the other smooth, attached to each set of cutters; the rollers 

 and cutters are raised or lowered by a simple gearing on each 

 side below the bed; the rollers revolve the same way as the bed, 

 and on tiiis account the two sections are fed from opposite sides 

 of the machine. 



The advantages claimed for this style of machine are — 



1st. The bed revolving with the rollers the lumber is carried 

 through the machine with a great reduction of friction in com- 

 parison with those machines with stationary bed, and conse- 

 quently there is a great saving of power. 



2d. This planer is admirably adapted to working stout stuff 

 for boxes and panels, curved and crooked stuff for chairs and for 

 carriage makers' use, &c., and at the same time works equally well 

 in long stuff; it is supplied with pressure bars placed between the 

 feed rollers and edge cutters, prevents the tearing upon any kind 

 or quality of lumber. 



3d. The machine being fed from both sides, the two men com- 

 monly needed to run a planer can run through two boards or 

 pieces at the same time; and as the gearing of each side is entirely 

 separate, the planing may be of different quality and thickness. 



4th. The machine is adapted to the finest kind of work, on 

 which it leaves an excellent finish. It will plain any kind of 

 stuff one-eighth of an inch thick up to four and a half inches, per- 

 fectly smooth, or any length from three inches upwards. 



This planer is remarkable for its simplicity of construction, 

 convenience of adjustment, strength and durability, and not liable 

 to get out of repair, [^i gold medal having been before awarded^ Dip. 



Smith's Wood Planing Machine.

Tins machine is very compact, is built entirely of iron and steel. 

 The cylinder is made of wrought iron with cast sfeel shafts, and 

 is capable of being run at a high speed. The whole machine 

 for feeding and planing various thicknesses of work from one- 

 eighth to four inches, is adjusted by a single screw, and as there 

 is an index which shows the exact thickness it is set for, is conse- 

 quently very quickly adjusted for any thickness required. The
