Abstract

This system comprises rotating shaft S on which two wheels R and R' are mounted. These wheels, driven by the shaft, are very similar. Characters are fixed to end 4' of levers 4 which are set on the periphery of print wheel R. Lever 4 is in its reset position. Lever 4e is in its printing position. The levers are maintained in either position by spring blades 11. Wheel R comprises also toothed crown 10 which can engage end 3" of lever 3. Wheel R' also holds levers 5, similar to levers 4, but their ends 5' are toothed and form toothed sectors. Lever 5 is in its reset position. Lever 5e is in its active position in which it comes into gear with toothed wheel 8. Wheel R' holds also toothed crown 10a in which can be engaged the end 3"a of levers 3a.

Printing System With Wheel

This system comprises rotating shaft S on which two wheels R and R' are mounted. These wheels, driven by the shaft, are very similar. Characters are fixed to end 4' of levers 4 which are set on the periphery of print wheel R. Lever 4 is in its reset position. Lever 4e is in its printing position. The levers are maintained in either position by spring blades 11. Wheel R comprises also toothed crown 10 which can engage end 3" of lever 3. Wheel R' also holds levers 5, similar to levers 4, but their ends 5' are toothed and form toothed sectors. Lever 5 is in its reset position. Lever 5e is in its active position in which it comes into gear with toothed wheel 8. Wheel R' holds also toothed crown 10a in which can be engaged the end 3"a of levers 3a. As for wheel R, the levers are maintained in either position by spring blades 11a.

Paper 7 to be printed on is drawn by a device, not shown, and passes on a piece 6 fixed to shaft S' to which wheel 8 is fixed.

Wheel R bears all possible characters on its periphery. Shaft S which drives wheels R and R' also drives coded device 1. This determines which character is passing under lever 3 and causes lever 3 to rotate if the character corresponds to the character to be printed. Levers 3 and 3a are actuated simultaneously by electromagnets 2 and 2a, and their ends 3' and 3'a set levers 4 and 5. Because of the rotation of shaft S, lever 5 comes into gear with wheel 8. The latter rotates and drives shaft...
