Fig. LXXI.

[Fig. LXXI.] shows a warp-thread forming part of the top shed by raising the leash; hence mail, L, is shown raised. The compound harness is supposed to be resting, which allows the warp-thread to slide up to the height of the required size of shed. This figure illustrates plainly the following warp-threads in [Fig. LXIX.]

Warp-thread No. 5, passing through leash a´, and harness 5, in [Fig. LXIX.] is the same.
Warp-thread No. 7, passing through leash a´, and harness 7, in [Fig. LXIX.] is the same.
Warp-thread No. 8, passing through leash a´, and harness 8, in [Fig. LXIX.] is the same.
Warp-thread No. 9, passing through leash a´´, and harness 1, in [Fig. LXIX.] is the same.
Warp-thread No. 10, passing through leash a´´, and harness 2, in [Fig. LXIX.] is the same.
Warp-thread No. 12, passing through leash a´´, and harness 4, in [Fig. LXIX.] is the same.

Fig. LXXII.

[Fig. LXXII.] illustrates the side view of a warp-thread where the hook of the Jacquard is not raised; hence, the mail remains in its resting place. Following the warp-thread towards c, the compound harness is shown raised, thus forming part of the top of a shed. This figure is designed to show the passage of the warp-thread through mail No. 3 of leash a, and harness No. 3, in [Fig. LXIX.]
