At e, f, g, are shown prisms of the size of the cylinder, by which the cards are guided and regulated in their run towards the cylinder, (direction of arrow); i and h represent round rollers, also placed in rack for guiding cards after leaving the cylinder, c; a and b, the needle-board; c and d, the needles of the machine. S represents the wires as inserted in cards for holding them in the frame.
THE JACQUARD HARNESS.
To the lower end of the hooks (c. in [Fig. V.]) the neck-cords are adjusted. The latter are passed separately through one of the corresponding holes of the perforated bottom board ([Fig. II.]) To these neck-cords are fastened the leashes of the Jacquard harness about 1/2 to 1 inch above the frame containing the rods which guide the neck-cords vertically as the hooks are raised and lowered. The different harness-cords are threaded through the comber-board in various ways called “Tie-ups,” which will be explained later.
The Comber-board and Methods of Figuring for it.
There are two kinds of comber-boards used upon Jacquard looms:
1st. Comber-boards made of a solid piece of material, either wood or porcelain.
2d. Comber-boards made in strips of either of the materials above named, and adjusted afterwards in a wooden frame.
