The Jacquard Machine Analyzed and Explained / With an appendix on the preparation of jacquard cards, and practical hints to learners of jacquard designing

by E. A. Posselt

[Fig. 5] shows the relative positions of punch and key when no hole is required.

O represents the Jacquard card as resting in the slot of the lower head. II. in [Fig. 3], marked X to Z, shows a full width view of this card.

The space D, in Figs. [4] and [5] permits the spring to be inserted regulating the key. A, B, C, solid parts of the upper head, (I., in [Fig. 3]). F, G, K, L, solid parts of the lower head, (II., in [Fig. 3]).

The cards are passed into and through the stationary part of the head at X, Z, and are attached to a “carriage” in the rear of the punch head.

Fig. 12.

Two methods are employed for moving the carriage:

1st. By a “skipper” at its rear fastened to the carriage, which moves in a rack of pins secured to the cutting table. This method of construction is used by the Uhlinger machine. Figs. [6] and [7] are front and side views of this mechanism. Figs. [8] and [9], the top view and sectional cut of the rack.

2d. The rack is fastened to the carriage, and the skipper to the table, thus reversing the first method. [See [Fig. 19], top view.] This method of construction is employed in the Royle machine.
