Abstract A franking machine having a printing head in which the values to be printed are manually selected by the rotation of valueselecting wheels, one for each printing wheel, by way of a toothengaging pinion integral with each value-selecting wheel and in which each toothed wheel is provided with an axial bore with gear teeth therein, which are engaged by a pinion integral with a coarse helical screw having a cooperating nut thereon. Each printing wheel is provided with a pinion which engages a toothed rack joined to each nut by a bar passing through the bore in the toothed wheel. The axes of rotation of the value-selecting wheels, the toothed wheels and the coarse helical screws are all parallel to the axis of rotation of the printing head, while the axes of rotation of the printing wheels is transversal of the axis of rotation of the printing head.
A franking machine of the type having a rotatable printing head in which the values to be printed are manually selected, comprising rotatable printing wheels, a value-selecting wheel for each printing wheel rotatably mounted and the manual rotation of such selecting wheels the values to be printed, a pinion integral with each value-selecting wheel, a rotatable disc having external teeth in mesh with each pinion, each disc having an axial bore provided with internal gear teeth, a coarse helical screw provided with an integral pinion in mesh with the internal gear teeth of each disc, a nut threadedly engaging each screw, a pinion for each printing wheel, a rack having a toothed portion and a bar portion integrally connected thereto, the teeth of the toothed poRtion meshing with a respective printing wheel pinion, and the integral bar portion passing through the axial bore of the discs and secured to a respective nut.

Claim 3
Dependent Claim
55 words
The franking machine as claimed in claim 1 wherein the axes of rotation of the value-selecting wheels, the discs and screws are all parallel to the axis of rotation of said printing head, with the axis of rotation of said printing wheels being transverse with respect to the axis of rotation of the printing head.
