Columbia Junior Single Drum Sander.
A four-roll single drum sander designed especially for polishing thin veneers and for use in small shops, box and furniture factories and other places where good work at high speed is a prime requisite, has just been placed upon the market by the Milwaukee Sander Mfg. Company, branch of the American Wood Working Machine Company, Green Bay, Wis. This machine, known as the Columbia Junior, is the first of its type the company have introduced and is shown in general view in Fig. 8 of the engravings. In its construction the sand cylinder has automatic paper tightener, is accurately ground, has hard surfaces and will take 30-inch sandpaper. One of the features, which is referred to by the manufacturers as of the highest importance and is patented by them, is automatic compensation of wear on top raising screw. Another feature is the separate regulation of the spring tension of every top feed roll, which enables the operator to increase the spring pressure of the feed rolls at will. In shops where sanders are used for a variety of purposes, a variable speed for the feed is very desirable, the device employed for this purpose in the Columbia Junior being such as to permit a change from 9 to 21 feet per minute. There is also an instantaneous feed stop and a brush, which are also important in a machine of this kind. The Columbia Junior is made in two sizes, 30 and 42 inches wide, to work up to 4 inches thick. The two sizes have tight and loose pulleys 12 x 8 1/2 inches and make 650 revolutions a minute. The smallest size occupies a floor space 5 feet 3 inches by 3 feet 6 inches, while the largest size covers 6 feet 3 inches by 3 feet 6 inches. The American Wood Working Machine Company have salesrooms at 109 Liberty street, New York; 94 Pearl street, Boston, Mass.; 3101 Chestnut street, Philadelphia, Pa.; 330 Lyell avenue, Rochester, N. Y.; 45 South Canal street, Chicago, 111., and Church and Basin streets, Williamsport, Pa. Those of our readers who are interested in the products of the company can save time by addressing the salesroom nearest to them.
