The No. 127 variety belt sander here illustrated is now being built by the Oliver Machinery Co., Grand Rapids, Mich., for pattern shop use. It is suitable for sanding concave and convex surfaces and the various irregular shapes met with in the manufacture of patterns, performing work usually done on disk and drum sanders. The table may be tilted to suit angular surfaces or draft on work. The machine is driven from a pulley mounted on a countershaft located on the base. On this base is mounted a frame that swings about the center of the countershaft and carries a supporting arm. On the latter are mounted two brackets, one of which supports the main idler pulley and tension idler, while the other supports the table and backing plate, forms, or flexible pads.
The machine will take belts up to 10 inches wide and 14 feet long. The backing plate is 10 inches wide and can be adjusted in and out to produce a suitable tension on the belt. it has holes drilled in it for attaching flexible pads. The main idler is leather-faced and adjustable up and down the entire length of the idler arm to suit different lengths of belts. The tension idler is also faced with leather; it fulcrums on the center of the main idler, and is balanced by weights to give the correct tension to the belt. A fork idler may be mounted on the machine in place of the table, for doing oval sanding. This machine may also be motor-driven, in which case a motor of two-horsepower capacity is provided. |
