Fig. XVI.
To get a clear understanding of this examine [Fig. XVI.] illustrating six different impressions of the needles. The circle shown with full lines in each of these six illustrations represents the correct position of the circumference of the hole, and the dotted circles the various errors that may exist.
- [Fig. A] shows the cylinder set in its proper place, which is indicated by the impression of the needle in the centre.
- [Fig. B] shows the cylinder is set too high, as indicated by the impression of the needle. [See arrow.]
- In [Fig. C] the cylinder is set too low.
- In [Fig. D] the cylinder is set too far to the left.
- In [Fig. E] the cylinder is set too far to the right.
- In [Fig. F] the cylinder is set too low and too far to the right.
- In [Fig. G] the cylinder is set too low and too far to the left.
- In [Fig. H] the cylinder is set too high and too far to the left.
- In [Fig. K] the cylinder is set too high and too far to the right.
If the machine produces wrong lifts of the hooks and the trouble is not found in the setting of the cylinder, nor in the hooks or needles, then ascertain if the cylinder is adjusted by means of the lever arrangement, close enough to the needle-board; for if it is not, the hooks will not be pushed far enough from the griffe-bars, and by raising the latter a wrong shed will be produced. When using a great number of cards in a set they are made to fold into a “rack.” This is done by attaching a wire 1 to 1-1/2 inches longer than the cards at the junction of, say every 12th, 15th, or 20th cards. [See c at [Fig. XV].]
The cards fall through a wooden frame, [Fig. XVII]., but the wires attached to the cards, being longer, can not pass through, and the cards will remain suspended, and subsequently fold together in a very compact manner.
Fig. XVII.
In [Fig. XVII.] we illustrate 156 cards arranged with wires attached to every twelfth card, as follows: between cards 156 and 1, 12 and 13, 24 and 25, 36 and 37, 48 and 49, 60 and 61, 72 and 73, 84 and 85, 96 and 97, 108 and 109, 120 and 121, 132 and 133, 144 and 145.
