Fence f, [Fig. 3088] is for slitting, and is made to swing back for bevel cutting, while f′ is for cross cutting, and is adjustable for angle cutting. Fence f is fitted to a plate p, [Fig. 3090], which rests on the table top, and also rests on the long slide g. This slide fits in a beveled way h, and contains a ⊥ groove. A tongue likewise beveled fits in the top of this groove, the tongue being permanently fast to the fence plate. The ⊥ bolt passes through the tongue and fence plate, having at its upper end a milled or knurled thumb wheel r, which when tightened up fastens the fence plate and the slide together.
Upon slacking the thumb wheel r, the fence plate and ⊥ bolt may be readily shifted, setting the fence as near to gauge as possible by hand, and the thumb wheel is then tightened, and the slide (which carries the fence bodily with it) is adjusted by means of the hand wheel h and its screw which threads into a lug from the table.
The fence f is pivoted to plate p at p, and the angling link which holds it in position is secured by a hand nut m.
The front journal of the saw arbor has a double cone, and by means of the nuts n n′, [Fig. 3089], can be regulated for fit independently of the back bearing and journal, the latter being also coned and capable of independent adjustment by means of the adjustment nuts m m′.
The countershaft for driving the saw arbors is below the machine, so that the saw that is not in use remains stationary.
Fig. 3091.
Examples of the work done on this machine are shown in [Fig. 3091], the various sections shown being produced by the vertical movement of the saw through the table and the cross movement of the fence. For example, for cutting out a core box, such as shown at 6, small grooves are cut through to remove the bulk of the wood, and the saw marks at the bottom of each saw cut serve as gauge lines for the workman in finishing the circular bore with the gouge, etc.
