Besides the frame, Fig. I. illustrates: Under I. the Jacquard plunger,
3/4 inch diameter, for guiding the griffe (attached to its head) when
raising. To strengthen the steadiness of this latter movement shoulders
are attached to the frame at the three places where the plunger slides.
Height of frame at _k_, = 2-3/4 inches.
" " _l_, = 2 "
" " _m_, = 2 "
Screws, _f_, dotted in drawing, on head of plunger, fasten the griffe
to it.
Part III. in Fig. I. illustrates the attachment for providing the
lifting of the plunger in a hand-loom, likewise the griffe, etc. This
consists of a triangular shaped frame 14-1/4 inches high, or less,
according to height of room. This part is fastened to the front part of
the frame by bolts at _o_ and _p_. In the slot at the top, between _r_
and _s_, a wooden cylinder of 3-1/2 inches diameter is fastened to an
iron shaft resting in the frame at _t_.
At 13 a leather strap is fastened to this cylinder and to the plunger
14. It will easily be seen that by turning the wooden cylinder in the
direction of the arrows, 15, the plunger will be raised with the griffe
fastened to its top. By reversing the action of the cylinder, the
plunger and griffe will return to their previous positions. The action
thus described constitutes a “single lift,” raising and lowering of
plunger and griffe for each pick.
