A Mammoth Surface Planer
Perhaps no machines have saved our industrious workmen more real hard labor than the lumber planing machines. To satisfy any one of this fact, let him watch a carpenter planing a large board, or if he hasno chance to meet one who is ignorant enough to take unplaned lumber when he can get the same planed for a trifle advance in price, let him try himself to plane a rough board, and he will soon be satisfied that, whatever prejudices may exist here and there against labor-saving contrivances, nobody can deny that the planing machines are a real blessing.
This blessing is greater in proportion that the labor saved is harder on the workmen, and as the planing of the heavy lumber used in ship-yards, etc., is among the hardest kind of labor, a planing machine which prepares this very kind of work is among the most beneficial of inventions.
Such planers are those of which we now give an illustration; they are adapted to the work of shipyards, car-shops, lumber-mills, or any work where heavy or rapid surfacing is required to be done. They are the heaviest machines ever built of their class, made entirely of iron and steel, very compact, strong throughout, and not liable to get out of repair. The cutter cylinder is made of solid wrought iron and carries four cutters, which allows much faster feed than other machines. The rolls are both weighted with independent weights at each end. The bed is raised or lowered on inclines, so arranged that in changing from one thickness to another there is no loss of time. Each machine will plane from 1/2 to 6 inches in thickness, and for green, wet, icy, or thick lumber, they are especially adapted.
These machines are without doubt superior to anything of the kind in the market, as regards quality of stock and workmanship, or quantity and quality of work which they will do. They are provided with tight and loose pulleys 14 inches diameter, and 6 inches face, and should make 750 revolutions per minute. Those planing 26-inch lumber cost, including counter shaft, $550; those of 30-inch, including counter-shaft, $650.
They are made by Witherby, Rugg & Richardson, Worcester, Mass., and called Farrar or Endless Bed Surface Planer. Their weight is about 4100 pounds. |
