Beattie Since the general introduction of the self-feed rip-saw into the machine equipment of the factory, the capacity for lumber consump- tion and the cheapening- of that portion of the work has been greatly increased. The style generally in use is the circular saw type, the later idea being to have the saw above the table, supplemented by an endless chain feed. This idea seems to be an improvement on the older style, one decided advantage being that the saw cuts through the material, thus reducing friction to quite an extent. The band rip-saw- for larger factories, where the necessary equip- ment and help to keep the saw in order are available, is doubtless the better tool, as the lesser waste of material, combined with greater speed, are strong points in their favor. There are still some plants that cling to the old style railroad rip-saw for use in matching up tops or large surfaces, especially on quartered oak goods, in many cases carefully matching up the ma- terial, which may consist of six or more pieces, laying the whole lot on the table and shoving them through the saw, cutting off the mu - plus from the'edge. This is a slow and laborious method, and can just as well be done on a self-feed machine with a great saving pf labor. Assuming that the light is good, and it certainly should be, the matching up can be done on a table behind the rip saw. and the one piece only that requires ripping is passed back and sawn to the ne- cessary width. Of course, it is understood that the stock has already had the necessary edging done to it after leaving the swing saw. The expert matcher is behind the saw in this case, and not in front of it. and sorts the material for figure as it conies to him. on a table of the required size, which can be m
