Abstract: 258,945. Rosback, F. P. July 1, 1925. Inking-apparatus.-A platen printing-press of the type in which the forme is mounted on a rocker and the travelling inking-rollers are mounted in a frame pivoted to the rocked is provided with (1) toggle mechanism for operating the frame by the movements of the rocker whereby the inking-rollers are, at the upper end of their travel, caused to contact with the ink-distributing cylinder for a substantial period, and (2) improved means for arresting the supply of ink to the distributing-cylinder when the impression is thrown off. (1) The rocker 2, Fig. 1, mounted on a pivot 4 is operated by a crank 5 and rod 6 connected to a pivot 9 on the rocker and the frame 7 carrying the inking-rollers 8 is mounted on the pivot 9. A link 12 pivoted at 18 to the fixed frame of the machine is pivotally connected at 17 and 19 respectively to a link 11 pivoted at 16 to the frame 7 and to a link 13 pivoted at 14 to an arm 15 on the rocker. By this arrangement of links the rollers 8 travel at a varying speed which is very slow when the rollers are at the upper end of their travel and in contact with the ink-distributing cylinders 10. (2) Ink is normally carried from a duct roller 21 to a distributing-roller by a messenger roller 24 mounted on an arm 32 on a rock shaft 31, Figs. 4 and 6, which is operated from the connecting rod 6 by a link 29 passing freely through an arm 30 on the shaft 31 and carrying springs 33, 34 engaging opposite sides of the arm. The pivot 9 of the connecting rod 6 is mounted in an eccentric bearing 44 which is rotated to throw off the impression and attached to this bearing is a rod 51 yieldingly connected by a spring 50 to an arm 49 on a rock shaft 48 to which is secured a bar 47 provided with a slot 46, Fig. 6. When the impression is thrown off the bar 47 is actuated to cause the slot to engage with a pin 45 projecting from the shaft 31 and thus prevent the roller 24 from engaging the duct roller 21. When the impression is again thrown on, the frame 7 engages a roller 53 on the end of the bar 47 to return the bar to its normal position in which it is locked by a spring pin 54.

IPC: H04L25/04
Filed: 1925-07-07
Abstract: 256,382. Houghtaling, W. A., and Western Union Telegraph Co. July 7, 1925. Automatic telegraphs; repeating systems using contact-making relays; distributor systems.-In an automatic telegraph system operating on the Baudot multiplex principle, the repeater equipment at an intermediate station comprises only a single set of relays functioning in each channel in succession, and locking circuits are unnecessary. The repeating apparatus interposed between adjacent line sections L, L<1> includes a rotary repeater and a set of polarized relays PR operable by impulses received from section L and connected to each channel of the system, unless as shown one channel is to be connected for local printing and transmitting, or to a branch line or lines, and a source of energy g for imparting impulses into the next section L<1>. The similar rotary repeater and set of relays PR<1> serve for transmission of signals in the opposite direction. Each rotary repeater comprises a pair of segmented rings r<2>, s<2> constituted as four channels with five segments in each: the magnets of the polarized relays are connected in multiple respectively to the corresponding segments of the channels of the ring r<2> and the armatures are connected in multiple respectively to the corresponding segments of the ring s<2> The brushes of the rotary repeaters are driven synchronously with those of the transmitters and receivers at the terminal stations A, C, but the transmitting ring s<2> is displaced relatively to the receiving ring r<2> through three segments so that a received impulse is not transmitted until the brushes have passed over two intervening segments, thus allowing time for the actuated armatures to settle down on their contacts before the impulsing current from the source g is passed, and so preventing chattering.
