Special flooring and Ceiling Machine.
It is not often that we have the opportunity of presenting as complete illustrations of wood-working machinery as are contained in the cuts of the Special Flooring and Ceiling Machine, made by the Glen Cove Machine Company, Limited, Nos. 28 and 30 Clay street, Brooklyn, N. Y., which are shown upon this page. Fig-, 1 which shows a side elevation of the machine, is the equivalent of what is ordinarily put forth with machines of this kind. Figs. 2 to 6 are additional to it, and show how the machine is constructed with reference to special features peculiar to the work produced by the company named. The ma chine in question has been specially designed for flooring, ceiling and that general class of work. It has six feed rolls, geared at both ends with gears cast from iron cut patterns. The company claim that the trouble which every operator has experienced with expansion gears that revolve on a shaft has by this construction been entirely avoided. In this machine the gears are secured to the shaft which revolves in boxes, by which means every journal on the machine may be oiled while running. The usual bevel gears and shafts for raising and lowering the feed rolls are wholly dispensed with, and in their place a simple crank and screw are used. The pressure bar or chip breaker before the cut to the top cutter head is adjustable close to or away from the cutting circle upon a bar supported by radial arms free to raise and lower to different thicknesses of lumber. The bar on the back side of the top cutter head and those on each side of the under cutter head are supported in housings cast solidly together, and made adjustable to and from the cutting circle head to permit the use of molding, beading or rabbeting cutters. There is placed above each matcher plate an adjustable pressure bar extending past the cut of the side heads. This presses on the board at its edge only, holding it firmly down on the matcher plate, thus compelling a perfectly straight cut by the side heads and always in the right place. A peculiar feature which will be noticed by a close examination of the engraving shown is that all parts of the machine are numbered. The construction system of the company is such that duplicate parts can be furnished which will fit, and these numbers are put upon the illustrations in order to facilitate supplies of this kind. Referring to the engravings, Fig. 2 shows the front end of the machine closed and ready for work. Fig. 3 shows the front end of the machine thrown completely open, giving free and unobstructed access to the under cutter-head for the purpose of setting or sharpening the knives. Fig. 6 shows the top cutter headwork with adjustable bar and chip breaker. Fig. 4 shows the variable feed works, indicating the manner in which the rate of feed can be changed to different speeds instantly while running. The device employed for fastening the side heads to the spindles, and which does away with the old set screw, is illustrated in Fig. 6. Many of the features shown in this machine are common to the entire series produced by this company. |
