Fig. 4. Common Jacquard Hook.

The illustration, Fig. 3, shows the next form of hook that was used, and which is used at the present time in many French machines. This also rested on a perforated board. The chief object of this hook was to remove the necessity of having springs to force back the needles. At the point marked A, a rod passed through the hooks from one side of the machine to the other, which kept the hooks quite firm. Near the top of the hook at positions B and B¹, two more rods were placed, one being at the back of the hook and the other at the front, the bottom of the hook being held firmly, while the rod B pressing against the back portion of the hook caused a certain amount of spring.

[Pg 4] The rod B¹ was to prevent the hook from swinging under the blades of the griffe when the latter was descending. The needles used with this hook had an elbow which pressed against the front of the hook. . . Read More
