Abstract: 725,653. Printing-machines. MONOTYPE CORPORATION, Ltd. Jan. 6, 1953, No. 361/53. Class 100 (2). Rotary machines; tripping arrangements.- A machine for winding paper on to a spool is provided with a marking device and supporting means therefor including a rocking arm, means for rocking the arm to move the marking device into operative position, a latch arranged to hold the arm and marking device in said position, and a pinion meshing with a rack on the latch and arranged to be rotated to retract the latch by a toothed disc which is rotated stepby-step by a striker carried on a roller which is rotated by a paper strip during its passage through the machine. As shown, a printing roller E<SP>9</SP>, Fig. 4, carried in a housing E<SP>3</SP> cooperates with a guide roll B<SP>2</SP> to print a coloured band along a predetermined length of strip C which is then rewound on a winding spool B'. The housing E<SP>3</SP> is carried by spindles on a winding spool B'. The housing E<SP>3</SP> is carried by spindles E<SP>13</SP> and E<SP>14</SP> engaging hooks E<SP>11</SP> and E<SP>12</SP> respectively, the spindles E<SP>13</SP> and E<SP>14</SP> being secured to pivotal arms E<SP>10</SP> and E<SP>15</SP> respectively. A link E<SP>18</SP> connects the spindles E<SP>13</SP> and E<SP>14</SP>, such that by actuation, through a hand-lever, of a shaft E<SP>20</SP> carrying the arm E<SP>19</SP>, the roller E<SP>9</SP> may be swung towards or away from printing position. During printing one end of the spindle E<SP>13</SP>, Fig. 6, rests on a stepped portion F<SP>16</SP> of a latch F<SP>9</SP> urged by a spring F<SP>11</SP> towards the left, while a pin F<SP>3</SP> on the roll B<SP>2</SP> rotates a toothed disc F<SP>1</SP>. The disc F<SP>1</SP> rotates a shaft F' and pinion F<SP>7</SP> engaging a rack F<SP>8</SP> on the latch F<SP>9</SP>, thus moving the latch to the right, the latch being prevented from returning to its initial position, under the action of the spring F<SP>11</SP>, by the weight of the printing mechanism acting on the latch by the shaft E<SP>13</SP>. When the latch F<SP>9</SP> is withdrawn from the shaft E<SP>13</SP> the printing mechanism drops under gravity, thereby allowing the latch to return to its initial position. If desired, the machine starting handle may be locked in position until the printing mechanism has been raised to operative position. In this case, a pawl pivoted to the starting handle'engages the handlever on the shaft E<SP>2O</SP>, Fig. 4, thereby preventing clockwise movement of the starting handle until the pawl is tripped by upward movement of the printing mechanism. Inking apparatus.-The inking mechanism, Fig. 5, comprises an ink reservoir E<SP>1</SP> closed by a plug E<SP>2</SP> carrying the housing E<SP>3</SP> which encloses distributing rollers E<SP>4</SP> mounted on spindles E<SP>5</SP> engaging slots E<SP>6</SP> in the housing, the housing E3 having apertures e within the reservoir El. The spindle of the lowermost roller is carried in a member E<SP>7</SP> engaged by a compression spring E<SP>8</SP>. Specifications 24615/05 and 17199/08, [both in Class 100], are referred to.
