[Fig. 19] represents the top view of [Fig. 18], and is designed to show the arrangement of levers, wheels, and catches of the complete rack as used for a 900 machine. The letters indicating the different parts correspond with the ones used in [Fig. 18].
[Fig. 16] shows top view and ground plan, and [Fig. 17] the front elevation of the “card-guide,” as constructed on the Royle machine. It is universal and self-adjusting to any width of cards from 3/4 to 3-1/2 inches; both guide-plates, C and D, are caused to move equally toward or away from the peg-punch, thus accurately centering the peg-hole in all cards.
Letters A, B, P, and numbers 1 to 12, correspond to those used in [Fig. 13.] E, F, H, K, are the three levers moving around pin, G, (the latter in even line with the centre of the peg-hole, P). These levers are held by screw, L, in any required position. Spring, S, holds lever, F, H, against pin, T, which in turn is fastened to the same plate as screw, L.
[Fig. 16] indicates the card-guide set for a 12-row card. Let us suppose it necessary to cut an 8-row card. Loosen screw, L, and spring, S, will instantly contract until each side of the guide has moved the required distance (two holes and two spaces between holes) towards the centre. Much valuable time is saved by the use of this guide, as it instantly adjusts itself to any width of card, and at the same time centralizes each card passed through the machine. In factories where broken cards require to be constantly renewed, the value of this guide is especially noticeable, there being no material interruption of the regular work of the operator, who can replace the damaged card at the moment wanted.
