This 'inverition relates to, print ng telegraph atiis and more particularly to m'eans' t be d'ed for enablingthe records oi a'rece'ivegl -ge to be readily distinguishable from a copy A transmitted message. Y J
It has previously been proposed to use a two? colour typewriter ribbon associated with posi ti'onin'g mechanism under the control of the keyboard; in'fs'uc'h' manner that an incoming messages record of messages under control of said trans r' and means for causing a mark of iden:
ti non to be printed automaticalhf the, margin of all messages of one kind of message tddis tinguis'h such messages from the other kind. For example, a vertical line,,slightly wa er than the height of the normal type, may be printed alongside each line of the m'es'sageof all local record copy, The appearance of a continu oil's line extending from top of bottom orth margin of all local record copy is thus produced; One" embodiment of the invention will now be described in conjunction with the accompanying drawing, in which:
Fig. 1 shows the mark identification apparatus in pirin tirig position, and
Fig; 2 shows a portion of the mark identifica= tio'n apparatus in non-printing position. x
The accompan ing drawing shows a same-eat part of the mechanism of a page printingftele graph receiver and an associated transmitter en'ablethe invention to be understood. As showii in Fig. l, the cam shaft of the transmitter earn-es;
a cam l which actuate's' a two-armed'leve'il for associated with a receiver of thekind-cor'r i prising a stationary platen and a moving typewheel chariot. Means are provided whereby in wellknown manner the receiver is connected to receive messages from a distant station, or operates print alo'cal record df'nies'sagesunder control of saidtransmitter. interposing membe fe' having a marking face 3A, is disposed along are the beginning-of-line position of the typewheel chariot and is mounted to slide vertically inguide i and normally held by spring 4 with ii p'er end lower than the ink-ribbon 5 by i which characters are printed on a sheet per carried by aplaten 6 mounted in a sta ti nary part of the machine.
;iriterpqsing member 3 carries a lever 1 atgedpya spring '8 to' rotate counter-clockwise. The typew'heel chariotfla carries a projection 9, which, when the chariot is in beginning-of-line position, pushes lever 'i into a position to be engages bylever 2, as shown in the drawing. this position, therefore, the cam I if set into on undercontrol of the keyboard acts on I, which in turn acts on lever I to lift inter- 3; ngmember 3 into the position shown in the drawing 'Inthi's' position it is temporarily held stop on the member 3 engaging a member H may be the upper end of the guide In ifi wh c'hinterposing member 3 s1ides. The upper end'mf the member 3 is then opposite the ink ribi io n 5 and also the end of a lever ll actuated by 'tli printing cam in the receiver.
Keys l3 are representative of a full set ofkeys. key ea'm of "a printing telegraph. tter. Universal bar I4 is adaptedto be:

The typewheel chariot is moved one step to the right in the drawing and the movement of projection 9 away from lever 1 allows that lever to be moved counter-clockwise to remove its end from con- I tact with lever 2. Fig. 2 shows interposing member 3 in the unoperated position and with. the typewheel chariot 9a moved out of begin-' chariot again returns to beginning-of-line position when a vertical line on the paper will again be printed.
When the receiver is actuated by a received message cam I will be stationary and interposing member 3 will not be moved at all. Thus'the vertical line will only be printed for a home record of transmitted messages.
As stated above the vertical line printed is preferably of such length that the lines printed extend continuously from top to bottom of the margin.

A page printing telegraph apparatus adapted to print messages received from a distant station and to print a local record of messages transmitted to a distant station by said apparatus, comprising a platen around which a message blank is adapted to be placed, means forcausing a mark of larger dimensions than the size of the printing type of said apparatus to be printed in 4 by said apparatus, a movable, vertical type member located near one extremity of said platen beyond the line of travel of said chariot, said member having a type face equal to the combined height of the printing type of said apparatus and the space between printed lines, means for transmitting movement of said cam to said member to raise same to printing position, a lever attached to said member and adapted to selectively engage said transmission means, spring means for normally urging said lever out of engagement with said transmission means, means attached to said chariot for engaging said lever with said transmission means upon return of said chariot to the beginning-of-line position thereof, means for holding said type member in printing position, a type hammer adapted to strike said type member, means in said apparatus for actuating said hammer, means operative during the actuation offsaid hammer for disengaging said type member from said holding means, whereby there is produced on all messages transmitted by said apparatus a continuous line extending from top 0! bottom of the margin thereof.
.5. A page printing telegraph apparatus adapted to print messages from a distant station and to print a local record of messages transmitted to said message blank to identify all messages of the margin of said message blank to identify all messages of one kind, said means selectively actuated by means under control of said apparatus and adapted to operate adjacent each line of printing of such messages of one kind.
