The following are the fourteen different movements that might be required in regular weaving. The figures show the number of threads up and the number down, thus:
equal first warp-thread up; second, third, and fourth down.
| 1. | = f up. | |
| 2. | = g up. | |
| 3. | = h up, doup raised. | |
| 4. | = i up, doup raised. | |
| 5. | = f and g up. | |
| 6. | = g and h up, doup raised. | |
| 7. | = h and i up, doup raised. [Illustrated by Fig. [XCIII].] | |
| 8. | = f and h up, doup raised. [See Fig. [XCV].] | |
| 9. | = f and i up, doup raised. | |
| 10. | = g and i up, doup raised. [See [Fig. XCIV].] | |
| 11. | = f, g, and h up, doup raised. | |
| 12. | = g, h, and i up, doup raised. | |
| 13. | = f, g, and i up, doup raised. | |
| 14. | = f, h, and i up, doup raised. |
These fourteen different movements cover all the possible changes in regular weaving. The movement (7) illustrated in [Fig. 8], in addition to forming the regular weave, is also necessary to the formation of the gauze weave.
These few explanations clearly show the great variety of effects possible for the designer; for he can figure with the regular method of weaving, and can also figure gauze weaving to exchange with regular weaving, forming a separate design on the fabric.
Modifications of the Single Lift Jacquard Machine.
Having thoroughly described the construction and action of the regular Jacquard machine, it now remains to illustrate and explain its modifications. Among the most prominent are:
- 1st. The Double Lift Single Cylinder Jacquard Machine.
- 2d. The Double Lift Double Cylinder Jacquard Machine.
- 3d. The Arrangement of Substituting “Tail-cords” in place of the Hooks, etc.
