Abstract: 13,209. Pierpont, F. H., and Lanston Monotype Corporation. June 5. Single-type composing and casting machines; justifying type.-Relates to machines in which the two-way movements of the die-case or matrixcarrier for positioning the dies or matrices over the mould are controlled by gauges, stops, or other controlling- mechanism. The parts are so arranged that the movements imparted to the matrix-carrier may be decreased, augmented, or multiplied, thereby enabling carriers to be employed wherein the distances between the centring positions of the matrices in the carriers differ from one another and from the distance between the gauges or controllers. Matrices of various sizes may thus be used in a machine. The parts are particularly applicable to the machine described in Specification 8633/99. The die-case B, adjustable by gauge-pin mechanism D, F, slides in a carrier B', which is adjustable by similar mechanism C. This mechanism is constructed as described in Specification 27,476/03. The various gauge-pins E, fifteen in number, are adapted to be embraced by jaws C<2> on connected levers C<1>, the right-hand lever being linked at c' to the frame and the left-hand lever at c' to a lever G. A stop H, thus positioned by the lever movements, is embraced by jaws C' on a pair of levers C<3> similar to the levers C', and these jaws position a stop B' on a tubular rod A' surrounding a draw-rod B<3> which is connected by a sliding joint b, b<1> with the carrier B<1>. The rod A<1> is connected to a supplementary mechanism comprising a lever A<3>, which is pivotally mounted, as shown in Fig. 2, on the frame J<1> and is linked at A<6> to a similarly pivoted lever A<2> connected to the rod B<3>. The levers A<2>, A<3> have different effective lengths or throws, and, in the present instance, are designed to augment or multiply the movement determined by the pins E imparted to the carrier B', the distance between the centring positions of the dies being greater than that between the pins E. In the die-case employed, there are fourteen rows of dies, fifteen in each row. The gauging-mechanism D does not require the supplementary mechanism, since no change is made in the set-ways dimension of the matrices. The gauging-mechanism C does however require the supplementary mechanism, since only fourteen of the pins E are used. The lever device As, A<3> may be employed as other than a supplementary positioning- mechanism. By making the fulcra of the levers A<2>, A<3> adjustable, the amount of movement for each centring position of the die-case can be varied. When the die-case positioning mechanism is used to effect the adjustments of the mould and justification devices, these devices must be modified accordingly. This is not the case however when the devices are operated as described in Specification 27,278/04. In the machine for perforating the record strip controlling the operations of the casting-machine, the justification indicator is based upon a number of positions corresponding to the number of gauge-pins employed.
