A No. 126 Universal belt sander has just been brought out by the Oliver Machinery Co., Grand Rapids, Mich., for the rapid sanding and polishing of line and edge moldings, patterns and various other parts made of wood. It may also be used in the polishing of metals. The abrasive side of the sand belt is in contact with the pulley faces. In addition to the safety features obtained by this arrangement, the breaking of sand from the belt is avoided and so the longevity of the belt is increased. The table rolls on ball bearings and is so easily moved- that a slight push causes it to roll the full travel of 36 inches. This construction is covered by a patent. The table top consists of plain wooden strips, spaced one inch between each strip. The different gaps allow any dust which may accumulate to drop through the table, and thus serve to keep the top clean. The table is 36 inches wide by 96 inches long and is provided with an adjustable bar to hold the work
Means are provided for taking up slack of the sand belt so that a suitable tension for the work in hand may be obtained. An idler is-supplied for this belt and this idler is adjustable up and down to the height of the work. It can also be placed in a tilted position to prevent the belt from running to either side of centers. An attachment is furnished for the power stand arm for use in sanding edge work. This attachment has an adjustable table that can be tilted 45 degrees up or down and raised or lowered to suit conditions. Attachments are also supplied for sanding edge moldings and irregular shapes, and the machine may be arranged either with or without a sanding pad attachment. The machine may have a motor drive or it may be driven by belt from a roller-bearing countershaft. The machine will sand to a center of 72 inches, and will take work on the table up to 54 inches in height and on the floor plate, up to 72 inches in height. The table has a vertical adjustment of 14 inches, and sanding belts up to 10 inches in width may be used. The machine occupies a floor space 72 inches wide and any preferable length. The over-all height is about 80 inches, and the weight, approximately 1400 pounds. |
