Small Jacquard machine (104 hooks)


Fig 16

The griffe or frame for raising the hooks is lifted by the straps A,A, Fig 16, which are attached to the pulleys B,B, and a cord C over a pulley on the same shaft as B,B, is attached to a treadle beneath the loom.

As the weaver presses down this treadle the griffe is raised, and when the treadle is released the griife falls of its own weight.
The cylinder is moved out and in by the pulley E, fastened on the bent iron bar, attached to the frame which carries the cylinder, when the griffe rises and falls.
D,D is a frame which lies in the turned-up portion of the hooks; only a few hooks are shown, and the outer bars of the frame.


There should be a bar in the frame for each row of hooks. This frame rises up and down with the hooks, the turn on the ends of wich must be of such lenght that when the frame is raised by the hooks lifted by the griffe, it will not be raised out of the tuns on those that are left down.
This frame is for the purpose of preventing the hooks from turning round, so that the turns on the upper end of them, as shown at A,A, Fig. 16A, cannot get out of position to be caught by the blades or crossbars of the griffe.
The lower ends of the hooks rest on a perforated board as shown in Fig. 16A, and tail cords are looped on them and pass through the perforated board as shown.
To these cords is fastened the neck of the harness.


Fig. 16A

In Fig.16A is shown a section through the spring box B. This box contains a spiral spring for each of the horizontal needles, the end of which press against the springs, which allow them to yield or move back as the cards press on their points; but recover them again when the card is moved away by the cylinder. Similar spring-boxes are now used.
