Bolts d and e are to secure the rest a to the elevating rest, and c c are the clamps for the two tools b.

Fig. 581.

[Fig. 581] represents a cross sectional view of the Putnam Tool Company’s gibbed elevating rest, there being a gib on the underneath side of the front shear. The elevating screw is pivoted by a ball joint. By employing a gib instead of a weight, the bed may be provided with cross girts or ribs joining the two sides of the shear, thus giving much greater stiffness to it.
