0hle Wisconsin Lumberman. WOOD-WORKING MACHINERY. In illustrating different machinery in the Wiscoxss LumBERmAN it is our endeavor to produce accurate repre- sentations of first-class machines only, and refer our patrons to first- class houses. The machines illustra- ted in this article may best be secur- ed through the house of 0. L. Pack- ard, 103 West Water street, Milwau- kee. The first representation is of a surface planer, made in several sizes, to plane from 18 to 30 inches in width and from 4 to 8 inches in thickness, either single or double surface. The peculiar merits of this machine may be mentined in the facts that it has weighted pressure rolls, three knife soLID sTEEL cYLINDER, with self-oiling cylinder boxes, and AqusTs TmCKNESS By PowE. Its speed in planing is from72,000 to 4,000 feet per hour. The*,second illustration represents EVABTs SHINGLE A"D HEADING MACHINE This is the original Evarts Patent Shingle Machine with improved taper works. As now made it is regarded as the very best One Block Hand- Feed Shingle Machine in use. It has a self-tilting table, so the opera- tor need not use his left hand, save to move the carriage. Any desired thickness of shingle can be made, both butt and top, and the taper or thickness can be adjusted in one niinute's time. The saw is adjusted by means of set screws at top and bottom boxes. It has an adva~ntage over other Machines in its adaptation to the sawing of Tight Barrel Head- ings Thick at the Sap Edge and Thin at the Heart. The working capacity of this ma- chine is 30,000 to 40,000 shingles per day from green logs of white pine or cypress, and in yellow pine 12,000 to 15,000 per day, depending on the skill of the operator. Variations from these figures may occur from at- tendant circumstances, and not due to the Machine, which has had the 5;06 i I I iq I i i I r p I' L
