摘要： A stamp printing machine has print drum carrying print wheels which are settable by push buttons to print a selected value of postage charge. The drum is driven by a mechanical device such as tensator spring motor. The motor is manually primed and a trip lever operated by insertion of mail item releases the print drum to rotate through one revolution to print the stamp on the mail item. The stamp machine may include a calculator on which the postage value may be manually entered. Electrical contacts operated by the rotation of the drum are connected across the M+ button of the calculator to add the postage amount to its memory.

摘要： A thermal transfer printing device for a franking machine uses a multi-strike thermal transfer ribbon. Mail items are fed to the printing device and frictional engagement between the mail item and the ribbon during a printing operation draws ribbon from a supply spool. After completion of the printing operation, the mail item is separated from the ribbon and the ribbon is partially rewound onto the supply spool so that each portion of the ribbon is used progressively a number of times. An encoder disc on the supply spool shaft generates signals indicative of the length of ribbon drawn from and rewound onto the spool to control rewinding of the ribbon.

摘要： Improvements result from using a feed roller always rotating at a constant surface speed to feed mail items successively with gaps between them from a stack to a franking machine without undue variations in the gap lengths when there are variations in the mail item lengths in respective stacks. A cam rocks a cradle about an input roller axis to bring a feed roller against the stack at a frequency to feed the items forward one by one. Gearing between rollers drives a two speed transmission to a cam via one way clutches. For envelopes shorter than a predetermined limit, the higher speed drive operates. When a rear mail guide member engages envelopes longer than the limit, a lever allows a pawl to disengage a wrap spring clutch disabling the higher speed drive and rendering the lower speed drive effective.
摘要翻译：通过使用总是以恒定的表面速度旋转的进给辊总是以一定的表面速度旋转的方式进行改进，这是因为当各个堆叠中的邮件项目长度有变化时，它们之间的间隙从堆叠到压印机之间连续地馈送邮件，而不会在间隙长度上有不必要的变化。凸轮围绕输入滚轴轴旋转托架，以使进给辊以一个一个的顺序向前馈送到堆叠。滚子之间的牵引通过单向离合器驱动双向传动到凸轮。对于短于预定极限的信封，高速驱动器运行。当后邮件引导构件接合长于限制的信封时，杠杆允许棘爪解除禁止高速驱动器并使低速驱动器有效的卷簧弹簧离合器。

摘要： An entire electronic accounting and controlling system for a franking machine is mounted on two connected printed circuit boards, one along the top of the machine and the other along one side of the machine within the machine casing. The top board carries four rotary encoding switches and press button switches which are scanned by signals from a microcomputer on the side board passing to a binary counter controlling a binary to decimal decoder to send multiplexed signals to the switches enabling the rotary switches to send four pairs of five-bit words along ten scanning lines to the microcomputer which delivers equivalent eight-bit error immune signals to duplicate non-volatile memories. The press button switches send signals along the scanning lines to enable a display module on the top board to display decimal digits according to the information stored in the memories. A printing drum is set mechanically simultaneously with the rotary switches. When a sealed door in the casing is opened a switch is automatically actuated to change over from customer mode to Post Office mode.
