Francis^ Writing Printing Machine. 



S. W. Francis, 1 Bond street, N. Y. 



This printing machine is intended 

 to be used by such persons as may 

 want to preserve legible copies of 

 their writings or ideas, and is special- 

 ly adapted for the use of clergymen, 

 editors, merchants, and literary men. 

 It is operated by piano keys, each of 

 which carries a letter, and by press- 

 ing on the key, two impressions of 

 that letter are made in less time than 

 it would take to write one. 



Fig. 1 is a top or plan view of this 

 machine, B being one of the sides, and 

 F (and C, fig. 2) are crossbars, bind- 

 ing the sides together. The types 

 are attached to hammers arranged 

 round a circle so as to strike up 

 against the stud, k, at a common 

 centre. The paper is placed in a car, 

 J', d' e' g\ between the rollers, h, 

 and i. The ink -band, p, moves on 

 four rollers similar to I, passing be- 

 tween the two sheets of paper. The 

 transmission of power is by means 

 of wires, such as s s' s", V V V", 

 working on bell cranks, T T' T"; 

 each key, K K' K'', is connected 

 with one of these wires. A spring is 

 attached by a string, S', to the car by 

 means of the hook V'. This car is 

 kept back by the cord, a', around a 

 barrel b", which is furnished with a
