New Sandpaper and Polishing Machine
The importance of sandpapering and polishing in various lines of work has long been apparent to manufacturers of wood-working machines, and the probability of producing a machine that would accomplish a finish of this kind equal or superior to that done by hand has long engaged the attention of inventors. The accompanying engraving represents a machine doing work of this kind recently produced by the Cordesman & Egan company, of Cincinnati, The manufacturers claim for this for this device that it is superior in quality and quantity of work produced, and also in the ease, convenience and economy of operation. They claim for it, further, that the feed is more powerful and positive than on other machines; that the brush attachment is arranged in a superior manner, and that every part is readily accessible. The usual all-around hand-feed, which is very liable to get out of order, has been dispensed with, and its bed is supplied with a hand-gearing by which the whole upper part of the machine is raised and lowered at once. The feed consists of eight geared rolls. The four feed rolls are set in the center and between the two drums, so that very short stuff can be worked. All the upper feed rolls and pressure rolls can be instantly adjusted by a hand-wheel placed in front-a matter of great convenience to the operator. The pressure rolls over the cylinder have an independent adjustment by means of small hand-wheels, shown in the engraving The brush attachment on this machine is placed inside of the polishing rolls, and the work is thoroughly brushed and cleaned before going through the last part of the feed-polishing rolls. Either or both polishing rolls can be vibrated at one time. The fact that the brush is put inside of the feed-polishing rolls makes it possible to run the drums in opposite directions, thus securing the great desideratum of having one drum raising the fiber and the second drum-the smoothing drum taking it all off the wheel. The brush cleanses the work before it passes through the feed polishing rolls. Still other advantages are pointed out in the manufacturers' circular. Three sizes of these machines are made, working 24, 30 and 36 inches wide. The latter machine will work up 37 ½ inches, thus enabling it to take a common door in a way to make a first-class job of it. In thickness the capacity of the machines is from 4 inches to the finest veneer.
