Abstract: 6187. McGinty, B. April 11, 1904, [date applied for under Patents Act, 1901]. Inking-apparatus.-Relates to the inking-apparatus of platen presses. The bed B is pivoted as usual at C on the main frame A, and is oscillated by the usual rods A' and crank-disks A'. Two bars B<7> are attached to the bed B, their lower ends being preferably attached to the cross-bar be of the bed by means of the piece b<9> and screws b ‹, Fig. 1<a>, to obviate boring the bar b<8>. An oscillating frame D is pivoted on the bed and carries the inking-rollers G in a usual manner. This frame is operated in the ordinary manner by rods D<1> connected to the fixed framing. A rotating ink-distributing disk E is mounted on the bed and operated by ordinary means. A curved ink-distributing plate F is pivoted at its upper end on the bed, so that it may be swung up to expose the ink duct. The plate F covers the ink duct, preventing ingress of dust &c., and is provided with an opening through which the duct or supply roller Q projects. The duct N and supply roller Q are mounted on arms M, Figs. 1 and 5, pivoted at their lower ends on studs on the bed, so as to be readily removable by a lateral movement. The bearing-blocks of the roller Q are arranged in slots in the arms M, and are pressed by springs against adjusting. screws T by which the roller may be adjusted to regulate the supply of ink on the roller movable. Blocks shaped to fit the duct and the side of the roller Q are provided to confine the ink laterally to the required limits. The upper ends of the bars M are slotted to engage an eccentric shaft U which may be turned to adjust the ink supply by causing the roller Q to project more or less through the opening in the plate F. Attached to the cross-bar d of the frame D are arms H, to the ends of which are pivoted arms I carrying distributing-rollers J by which the ink is distributed on the plate F and transferred to the disk E. Springs K hold the rollers J down on to the plate and disk. The roller Q is operated by a ratchet R engaged by a pawl on an arm W which is pivoted loosely on the shaft U and is operated by a cam Z on the frame D. The cam is preferably clamped to the frame by a strap j and bolts. The shaft U may be turned by the operator to adjust the ink supply at any time by means of a worm in a box m operated by a hand-wheel or finger-piece p. The worm engages a worm-wheel on a shaft t, an index finger r and scale being provided to indicate the adjustment. A strap b<3> is connected at one end to the shaft t, and thence passes round pulleys u, v on the bed to a pulley w on the shaft U, and is attached to a spring c<3> connected to the bed. The strap is clamped by a screw to the pulley w, so that when the shaft t is rotated the shaft U is rotated correspondingly. The distributing-rollers J may be disposed parallel to each other and square across the machine, or they may be disposed at an angle to distribute the ink better. Cams L are provided on the arms H engaging the arms I for lifting the rollers.J from contact with the plate F &c. when the machine is idle.
