The shiftable stop member 95 is connected through an arm 103 thereon and alink 110 to a. bail 107, said bail and stop member being held in normal position by a. spring 102, which causes the arm 103 to bear against the escepement bracket 33. The stop member 95 is rocked to its double speee feeding position, (Fig. 6) against the tension of the said spring 102, in the following manner.

To explain more clearly the double space iiioven'ient's of the typewriter carriage let it. be assumed that the carriage has reached the ten thousand dollars position in an adding.

If we now print inthis position, the escapement mechanismwillkoperete as usual to permit the carriage to advance a. single letter space distance on tlio return stroke of the type:

When the (log rocker returns to normal posi-' tion at the rise of the numei'nl key, the loose dog is to the left or" the adjacent tooth-28 and so engages with the next moth beyond: that, permitting n double space movement of the esoepeinent Wheel before the dog 30 is hronght to Test against the stop ll. with the result that the carriage is fed two letteri spaces. Automatic double speeing is in like manner eileeted the decimal point posit on n u o i and at any other desired po nts in the own pnting none by correspondingly looeted mp1 pets 1%.

To make the double s ence mechanism ineffective, which is desirable when the oomputing machine is set to non-edd or disoonnee-t, I have found it advantageous to pivot n above me :ld key 89,

the thrust rod 81 to rock n bail iii: by means:

of an arm 117, which pivoted to the bail at 118 end held against a. pin 119 project'- 112,! 'Irom the bail, by means of a. spring 120.

i l/hen the bail 116 is rocked it causes a down- Word pull on the link 121 connected to an, arm 1512 extending "forwardly endv laterally. fron'i the hail-carrying frame 108.

It will be seen that the screws 112 have reduced portions 127 which bear in holes 128 in the plunger bracket 111.
