Hooks. A description of the great variety of hooks and needles which have been used and which combine different ideas as to their relative values and adaption for the various machines in which they were or are used, will be both interesting and instructive.
In the old jacquard machine the hooks rested on a perforated board, through which the neck cord passed, and the bottom of the hook was bent up about five inches, as shown in Fig. [1]. Bars were passed through the turned up portion, as shown in the illustration, to prevent the hooks from turning. The bars formed a frame which was lifted when the griffe was raised.
The next hook, as shown in Fig. [2], was flat. This also rested on a perforated board, and, to assist in keeping the hook in position, the needle was twisted around the hook. This kind of hook and needle required too much time and labor when one had to be replaced.
