Bevel Sawing Machine or Combination Mitre Sawing Machine

In this machine, which is shown in Figs. 3099, 3100, and 3101, the construction permits of the saw being set so as to revolve at other than a right angle to the work table, which is rigidly secured to the frame of the machine.

Fig. 3099 is a general view, while Figs. 3100 and 3101, are sectional views of the machine.

This machine is constructed by J. S. Graham & Company, and its action may be understood from the following:

The table is firmly bolted to the frame, and is fitted with the necessary groove slides and fences for rip sawing and cross cutting. It is also provided with a removable piece, which allows the use of wabbling saws, dado heads, etc.

The sides of this machine a, a, Fig. 3099, are cast with an extension for countershaft. Referring now to Figs. 3100 and 3101, the upright piece i, i, with arms b b, and g, g, is bolted to the frame as shown. The arbor frame m, m, is gibbed to t, t, by the circular piece u, and is moved to any angle by the hand wheel z, which operates the worm w, which in turn moves the arbor frame m, m. This arrangement does not require any locking device to hold the saw in position. As the centre upon which the arbor swings is in the intersection of the planes of the saw and table top, the opening in the table needs not be larger than for the ordinary saw. When cutting a mitre the saw takes the position j, Fig. 3101. When cutting at a right angle the saw takes the position j′ and the arbor takes the position p′ n′.

The saw arbor can be raised and lowered by the use of the hand wheel which operates the screw b (Fig. 3100.)

There is an accurate index located in front of the machine in sight of the operator, marked from 0 to 45°.

The iron table is of one piece 4 feet by 3 feet and fitted with the necessary groove slides for ripping and cross cutting gauges. It is also provided with removable piece e, Fig. 3101, allowing the use of dado head, etc. The table is provided with a bevel slitting gauge s′, and cross cut or mitering gauge x′, Fig. 3099, which in connection with the angular adjustment of the saw enables the operator to get every conceivable plain or double mitre ever required. The pulleys a′, b′, are made wide to allow the belt to travel as the saw is inclined. The pulley b′ takes up the slack of the belt. The countershaft and tightener are a part of the machine and can be run wherever a belt can be brought to them.
