VARIOUS FORMS OF MOLDING MACEINE.—The Prgibil Serpentine Nader, EhOW11 in Fig.
4, is adapted to a wide range of work, but is especially fitted for making such moldings as extend around the backs and ends of sofas. There is a horizontal spindle. bearing lly-cutters at each end, those on one end extending partly a horizontal upper table bearing a proper guide or fence. The work is laid upon the top of this cutter, and guided against a gauge and collar, which deter mine the position and depth of the molding. Flat work is done upon adjustable tables borne on knees at the side of the machine, the cutters on the other end of the spindle from that for doing the serpentine work, working over those tables.
The Variety Wood worker.—For American use what is known as the variety wood-worker has proved a great boon, having for small estab lishments producing a variety of work a great range of size and variety of character of work. Such a machine is in tended for out of wind, ortaper surfacing, rabbeting door frames, rabbeting and facing inside Hinds. jointing, beveling, ploughing, making glue joints, squaring-up bedposts. table-legs, etc., raising square, bevel, or ogee panels, working beads and circular moldings, ripping, cross-cutting, tenoning, etc. The arbor is horizontal, and bears at one end a cutter heed, and at the other is arranged for a saw or an auger ; this latter being attached to the free or overhung end.
The cutters on the rotating bead work through a divided horizontal table provided with a vertical fence ; the boring end has a separate table, borne by a bracket and having its own fence. While this machine has not the range or dimension nor variety of work that is characteristic of the universal wood-worker, it is a very handy class of machine for small shops, and a and money-earner.
Shaft aru Pole-cutting Machines.--The shaft and pole-rounding machine shown in Fig. 5 has four cutter heads, each having three flat shear-cut knives. These heads are used for rounding, containing various widths of knives from 14 to 3 in., their edges ground different shapes to suit the work. Two adjustable rings or guides surround each head, and are
adjusted to or from each other for regulating the depth of cut. The fourth head, which forms a buzz-planer attachment, is furnished with straight-faced knives id. wide, with adjustable tables, and a stationary fence, on each side. The machine will work round, oval, sharp, or chamfered work, dress up fettles, fit carriage-body parts, and answer various other purposes.
The shaft and pole heel-tapering machine, shown in 6. is for tapering and finishing the heeis or bent ends of shafts. There are two disks, each 24 in. in diameter, and each bearing in its face three flat knives set at the proper angle to give a shear cut, the maximum length of cut being 18 in. The end of the pole or shaft to be tapered is placed on the table, between the disks, between the paral lel guide and cutter head, and moved toward the spindle until a stop or end gauge is reached. By repeating this operation with the opposite head, both sides of the shaft pole are fin ished without turning over or reversing the work.
Panel raising is an important operation in sash and door manufacture. There is often used a machine having two entler-heads. one above and the other below the table, with a wide table to support the stuff, and a supple mental table or frame in front to suit the width of the panel. The cutters on these heads, both of which are vertical. are set at an angle to produce a drawing mit, and finish the surface smooth ; and as they have no corners to wear away, the Lads are not easily destroyed and last a long time. The under head rises and lowers with the table, and has also a vertical adjustment on the bed for accurate setting ; it is belie.: direct from the countershaft. There are two geared sectional feed rollers and a friction roller in the table, with a spring and pressure bar to retain the stuff in place. Such a machine as this !nay. by removing the long hold-down spring, and putting in other heads and cutters, be turned into a machine for sticking sash, molding., etc.
