Idle Suitable mechanism 14 comprising a fixed positiong bar, a set screw, and'a returning spring is Figs. 6 to 10 are detail sectional views provided to return the shift key and type are to initial position.

In operation the striking mechanisms are in normal position as shown in Fig. 2. When it is desired to print the letter B on the type bar 4, for instance, pressure is borne-down on the key button 3 of the key lever 2 which assumes the position shown in full lines in slot 10, to be shifted by the pin 9 on the type bar 4 into the position shown in Fig. 7. The

pin and slot connection 9 and 10 between the i type bars 4 and 4' merely acts to shift'the printing. position of the type bar 4 when the two type bars are moved relatively longitudinally b their res ective key levers.

By pressing both the key buttons 3 and 3 simultaneously as exemplified in full lines in Fig.8, both of the type bars 4 and 4' will move together toward striking position. This is due to the fact that type bar 4 carrying the .pin 9 is not shifted relatively to the slotted type bar 4 hence both of the typev .bars will move forwardly at the same time and at the same rate of speed. However,,the

single letter which is a. combination of the lettersG-J on the type bar 4' is made more than type high with respect to the letter B on the adjacent type bar 4 so that it will project outwardly a little further than the letter B, thereb allowing only 'the combina tion character. J to be printed. Thepin 9 maintains its position in the slot 10, as shown in Fi 8. The letter B will be slightly removed rom the platen as shown in Fig. 9 and the combination letter G-J will be in striking position against the platen as shown in Fig. 8. However, when both of the keys- 3 and 3' are pressed, and the key button 3 is pressed sli htly in advance of the key 3' as shown in Fig. 10, the type bar 4 will be slightly in advance of the type bar 4 which makes up for the prominence of the combina-' tion character G-J, and both the combination character and the character B will strike the platen simultaneously and print both the character B and the combination character GJ, Fig. 3. During this operation the pin 9' will move slightly longitudinally in the of printing position with respect to the platen and the figure 1 will be in printing contact as shown in Fig. 4, thus enabling the character 1 to be obtained with the same striking mechanisms.

If the shift key 6 and both keys 3, 3 are all depressed simultaneously or the shift key depressed and followed by the simultaneous depression of both keys 3, 3' the figure 1 and the letter S will print as shown in Figs. 4 and 10 thus enabling a different combination of printed characters to be obtained.

By operatively interconnecting the two type bars or printing members thereby causing one to shift relatively to the other, more letters can be printed with a given number of keys than heretofore known to be printed in machines of this character.

In Figs. 11 to 19 which is a selected embodiment of the invention in a modified form 20 designates a striking mechanism comprising the key lever 21, key button 22, and type bar 23 which is operated through an intermediate link 24. A shift key 25 operatively connected to a type bar comb 26 shifts all the type bars in relation to the platen 27 in a manner well known in the art. A universal bar 28 is adapted to operate the platen roller 27, Fig. 12, and a stop bar 29 limits the upward movement of the key levers. The type bar 23 of the striking mechanism 20 is provided with a pin 30 which is adapted to engage a slot 31 in the adjacent type bar 23 which is an operative part of the strikin mechanism 20. Suitable mechanism 33 and 34, Fig. 12, is operably connected to the key lever and type bar to return the same to initial position.

The striking mechanisms are in their nor mal position as shown in Fig. 12 and for the purpose of illustration the same printing characters will be used for reference as.employed in explaining the device shown in igs. 1 to 10. ,When it is desired to print "the letter B the button 22 is pressed as shown in full lines in Fig. 13 allowing the type bar 23 to move forward to normal printing position; the pin 30 is free to move its required distance in the slot 31 without in any way affecting or shifting the type bar 23'. The type bar 23 will move inwardly in normal printing position as shown in Fig. 13 and the letter B will be printed, Fig. 18.

When the key button 22' is pressed to operate the type'bar 23' this type bar will move to the position shown in Fig. 14. As this type bar,carrying the lower letter S is being guided by the pin 30 on the type bar 23 the type bar 23' will be raised and cause the letter S on the lower part of the type bar 23' to be printed.

When both of the striking mechanisms 20 and 20 are operated simultaneously as shown in full lines in Fig. 15 the type bars 23 and 23 of each mechanism will move together while the type bar 23 will be in the position shown in Fig. 16 with the letterB away from the platen and therefore not. printed. If both the character B and the combination character G-J are desired to be printed at the same time, the striking mechanisms 20 and 20 are both operated with accent on thestriking mechanism 20 and the key levers.

of each striking mechanism will be inthe position shown in Fig. 17. This will cause the type bar 23 of each striking mechanism to bemoved slightly in advance of the type bar 23' of the other striking mechanism and bring the face of both the character B and the combination character G-J in alinement so 7 that both of these characters strike the platen simultaneously and are printed.

By pressing the shift key 25, Fig. 12, the

type bar comb 26 will cause the type bars of all the striking mechanisms to be moved on their axes 32 thereby shifting the relative osition of the characters in relation totheir ormer or normal printing position on the platen. When the striking mechanism 20 is depressed its ty bar 23 will move forward as formerly, l lt the bottom portion of this type bar carrying the figure 1 will print;

' the letter B being. raised from its normal printing position. If the shift key and both of the striking mechanisms are depressed [simultaneously both of the bottom characters of the respective striking mechanisms will be printed due to the new rinting posi tion caused by the operation 0% the type bar comb, Fig. 19.

While Ihave shown the type bars inter- I connected with a pin and slot arrangement,

it is to be understood that a similar arrangement may be made with the key levers; or instead of just having two characters on each type bar, more may be employed, and

the arrangement of the slot and pin changed to cause more than two letters to be printed from the same ty bar.

Changes may struction and arrangement of the partswithout departing from the spirit of the invention or sacrificing any of its advantages and the right is hereby reserved to make all such changes as fairly fall within the scope. of the following claims I claim; 1.
