If several sets of cards of one design are required for starting a corresponding number of looms, and the first set has been produced by the “piano machine” exact duplicates can easily be obtained at small cost to the manufacturer by the “Repeating Machine.” This machine is built by Messrs. John Royle & Sons, Paterson, N. J., and is illustrated by [Fig. 25] in a perspective view.
[Fig. 26], p. 94, represents the front elevation of the throat-piece through which the cards that are to be cut pass, the carriage on which it is supported, and the mechanism employed for imparting a rising and falling motion to the carriage.
[Fig. 27], p. 95, is a vertical longitudinal section of the upper portion of the machine.
[Fig. 28], p. 95, gives a perspective view in detail of portions of a selecting-needle and key-wire and a lever connecting them.
[Fig. 29], p. 95, gives a view in detail of the mechanism employed to turn the pattern cylinder.
The cards to be duplicated (N, N, [Fig. 26], p. 94,) are arranged upon the card race-arms (M, M, [Fig. 26],) in the same manner as upon a loom. The uncut or blank cards, having been previously laced together, (E, E, [Fig. 26]), are piled in the rear at the base of the column, and thence passed forward through the machine, and delivered finished in front.
The perforating of the cards is performed by a vertically reciprocating die, (D, [Fig. 26]), and a set of punches (C, [Fig. 26],) carried in a fixed punch-head, and capable of being pushed upward when such movement is not prevented. The cards commonly used are of a size to receive 600 holes, and hence that number of punches are required.
