This inif'ention relates to printing' telcgraph systems et the in which a single t1'a1i:5ii'iisf,-:i n circuit between the transn'litter and the receiver (or receivers) controls all the operations et the latter, including` setting ot the ty .ve Wheel or type-carrier, making' the imp t d eltecting spacing' between iinprints. in systems et this class the type or printing' charm Yers are arranged in two rows on the type wheel, which is rotated step by under the control ot 'the usual electro- Y escapement t bring the desired to jthe priiiting' position, but in orm either row at will one or ments ot the printin couple must be To make the shitt it is necessary to rotate the type Wheel to a shift position and make what is virtu ally an idle. stroke ot tlf-e p' ating elements. For example, supetters ot the alphabet are in one row pe Wheel and the numerals, iracpiu'ictuation marks 'in the other, and desired to print the letter G, toliL-l Y; tilde E loweil by a n'. faber, say 5, then another letter.

this operation the type Wheel is rotated step by sten until C p lf is at the impression point. The letter is then printed, atter Which the type wheel is to the suitt position. An idle stroke is then made (or a period is printed type has a period the shi'lftposition), by proper cooperation with the printaten shifts the latter to the other or ron' oil type. The 'wheel is new rotatefjl to bring' 5 to the printing' position, '-iprint is made. then in order to shift back Lie letters rouv the type Wheel must be again rotated the shitt position and anothei die stroke.

Upon ection it will be seen that rotati 'type Wheel to the shiitt position and man 'gj an idle stroke requires a certain amount ot time, and that this time is lost since soi/'ul letter or nun'ieral printed in the operation. ,in usine' the system to les on stock oxclanges or other ei:- rlianzfrs the loss ot time is sometimes very ions. as when the uiarkotf7 is active.

serial No. 144,230.

in which the shitt from one row ol' type to another can be effected at any position of the type Wheel, thereby effecting' a marked increase in speed ot operation. In tact, With the preferred embodin'ient hereinafter de sci'il. ed We have been able to increase the speed much as 'forty per cent, depending somewhat, et course, upon the skill of the sending;` operator. Another object is to provide tor the purpose stated instrumentalities which can be added to or incorporated in exiting; systems at reasonable expense. A Yfurther object is to provide shift mechanism and shitt controlling mechanism Which is not lin ilcd to use in one-ivire systems. To these and other ends the invention comprises the novel iteatures and combinations hereinafter described.

lfn carrying` out our invention in the prer red manner We make use of a principle which has been employed 'for other purposes in printing; telegraphs, namely, variation 'in the strength ot the current used to control. or

@were this principle has not heretofore been employed to elicct the shitt in a one-Wire tape-printer or ticker system. By such n'ieans, We are able to do with a single transri circuit what has hitherto required t two in such. systems, and We thus obhe desired increase ot speed Without to the large expense of a second Wired the various forms in which the invention can be euibodied We have selected tor speci'lin llustration and description herein the one which at the present time We consider the most etllective. This for n is based on a Widely used system in which the current sent over the transmssion circuit is ot alternating` polarity, causing` corresponding' alternations in the polarity ot the electromagnets which control the type Wheel. escapement oit the recei Ver thereby causing; or permitting' the type wheel to rotate step by step. 1When the dcsirod chara-.ifter has thus been brought to the impression point the linal current impulse is prolonged, ei abling such impulse to energize a magnet ot longer time-constant, known generally the printing' or press magnet. 'lhe latter, thus energized, actuates the platen and spaces the tape along one step. ln accordance with our invention as applied in the preterred manner to the system referred to, n'eak current causes imprints to be made from one row et type, say the row containnier-1l euses lo operate llie pres zuid shi'iil ningneis en local eireuils inner the control ol relays in vhe transmission line.
