THE BATTEN MOTION.

Fig. VIII.

[Fig. VIII. ]represents the batten motion to be attached to the guiding-rod, [see No. 14, in [Fig. I].], and the frame, [see No. 16, in [Fig. I].] The batten, 2, is connected to a triangular lever by means of lever, d. Another vertical lever connects the lower part of this triangular lever to a projecting bolt, k, fixed to the guiding-rod of the griffe. By raising the guiding-rod, thus raising lever, k, in the direction of the arrow, the batten is thrown outwards, [see direction of arrow below c], returning again to its former position at the lowering of the griffe. f indicates the place where the triangular lever is fastened (movable) to the projecting bolt, extending out of the frame. a indicates the place for the cylinder. Part 1 of the batten is movable at l in the direction of arrow, s, allowing the cylinder to be inserted. Part 1 is fastened (after putting the cylinder in at a), to 2 by means of the screw, n.
