TABULATING MECHANISM FOR PRINTING TELEGRAPHS.

Application filed June 25, 1923. Serial No. 647,510.

T 017 whom it may concern:

Be it known that CARL Euro Names, a citizen of the'llnited States, residing at Brooklyn, in the county of Kings and State 6 of New York, has invented certain new and useful Improvements in Tabulating Mechanisms for Printing Telegraphs, of' which the following is a specification.

This invention relates to a tabulating and paragraphing mechanism. for printing telegraphs.

Heretofore data in tabular form, when sent over printing telegraph circuits, has necessitated the sending of a plurality of spacing signals to the receiving printer between the various columns in order to prop: erly align the matter. A great portion of the line time is taken up in sending these spacing signals and. such transmission, is slow and necessarily costly.

The objects of the present invention are to provide a tabulating device for printing telegraphs which will eliminate the necessity of sending spacing signals to step the spacing mechanism of a printing telegraph machine for paragraphing and tabulating purposes, and such other objects as are at tained by the preferred embodiment herein disclosed of which Figure 1 is a fragmental and partially diagrammatic view showing the tabulating mechanism and circuits-and only so much of a printing telegraph machine as will be necessary to understand the invention.

The details of the printing telegraph machine of which the fragmental portions are here shown, are disclosed in copending application Ser. No. 390,598, filed June 21,

1920, to which reference may be had for a complete description. The parts of the printing machine are given the same reference numbers in the present case as they have been in the co ending'application to facilitate understan ing of the invention and its ap lication.

On the rawing 10 represents the printermagnet, 18 is the one of the five selector magnets which is energized when a spacing signal is received,'43 is the printer bail operating shaft, 116 is the carriage ball race, 117 is one of the balls upon which the carriage is longitudinally and tiltably notch 3 and shoulder 4 formed thereon. A

control plate 5 is supported pivotally by members 6 and from rod 1. Pivotally secured to an extension of member 6 is a hook member 8 which is guided by and slidably mounted on an extension 9 'of shift lock arm 133. A spring 11 secured at one end to a collar 1.2 on rod- 1 and at the other end to member 7 is normally stressed in a manner'to force plate 5 rearwardly'and to the left in the figure, against shoulder 4 as shown. Extending downward from memher 6 is a contact carrying member 13 upon which are mounted contact springs 14 and 15 separated by insulation 16. An arm 1.7 secured to printer bail shaft 43 is arranged to co-act with contacts 14 and 15. A pair of contact springs 19 and 20 are normally held in open relation and controlled by a member 21 which is pivotally carried by a pivoted arm 22. Arm 22 is normally held against a stop 23 by a spring 24.. Member 22 is held'against a stop 25 by a spring 26 and has a cam surface adapted to ride up on a pin 28. It will be understood that members 22, 23, 24, 25 and 28 are suitably supported from the printer frame not shown. An arm 29 secured to printer bail shaft 43 is adapted to engage a shoulder on member 21 as shown. Pivotally mounted on a suitable support (not shown) is an arm 30 which carries a member .31. adapted to engage a projection on hook member 8 only when the printer carriage is in shifted position. An extension 32 of a printer letter actuating bar is pivotally connected to arm 30. A series of slots. 33 cut into plate .5 are adapted to receive, stopmembers 34. A member 35 carried by ball guide rack 118 is adapted to engage stops 34.

In addition to the circuits shown in application Ser. No. 390,598 through magnets 10 and 18, circuits as here shown from battery 36 through contacts 14, 15,19 and 20,

magnet 10 and the N0. 3 magnet 18.

resistance 37 to magnet 18, and through magnet '10 are provided.

Upcwrfvirm.

To operate the 'tabulating mechanism stops 1-1- are first properlv arranged in slots #13 in accordance with the columner spacing desired. The matter to be printed is trans mitted in the usual way. To space between columns a shift signal is sent to lock the carriage in shifted position as described in application Ser. No. 390,595. \Vith the carriage in shifted position hook member 8 is moved by member 1) in a position to be engaged by member 3 A signal is then transmitted to actuate extension 32. Magnet 10 will be energired on this signal by the circuits shown in Ser. No. 390,598 and will move extension 32 to the left in Figure 1, causing member 31 to engage member 8 and move it downward. Movement of S downward Will rock plate 5 forward against the/tension of spring 11 and as plate 5 is moved off shoulder 4, spring 11 will force it into notch 3 where it will be locked. Movement of plate 5 into notch 3 throws contacts 11 and 15 against arm 17 after magnet 10 has de-energizcd' and closes these contacts. This closes a circuit through Energization of this magnet 18 sets the printer mechanism so that the spacing actuating bar will be operated as 10 energizes in this circuit. As 10 energizes, in addition to operating the spacing mechanism, arm 17 will be actuated to permit springs 1st and 15 to separate, and at the same time arm 29 will move member 21 in a manner to permit contacts 19 and 20 to close before contacts 14 and 15 open. The energizing circuit for magnet 10 will be shifted through contacts 19- and 20 as the movement of shaft 43 progresses. As the end of the energizing stroke of 10 is reached surface 27 of member 21 will ride up on pin 28 and member 21 will be disengaged from arm 29. Disengagement of member 21 permits spring 2.4. to become effective and a um 22 together with member 21 will move forward and will separate contacts 19 and 20, interrupting the energizing circuit for 10. Magnet 1.0

- and the printer bail parts will restore under influence of a spring (not shown) and '17 will again close contacts 14 and 15. This cycle will be repeated resulting in spacing of the carriage until member 35 engages a stop 34which has been locked in forward position by movement of plate 5 into notch 8. When this occurs the movement of ball guide rack 118 will carry plate 5 with it to the right until plate 5 is in a position to slide over shoulder at under the tension of spring 11. Movement of plate 5 over s oulder 1 moves contacts 14: and 15 into position where they can not be closed by arm 17 and upon the restoration of magnet 10 the printer will come to rest.

It will be obvious that this mechanism may be made to operate independently of the carriage shift by simply providing a special actuating bar which will cause operation of 8' each time its signal is received. It will also be clear that the invention is applicable to other commonly known telegraph printers such forcxample as typewheel and disc selector machines and is not limited to the particular embodiment herein. disclosed.

Having described one form of my'invention what is desired to be secured by Letters Patentand claimed as new is:

i. A printing t-elegra 'ih machine comprising printing, carriage, and spacing mechanisms selectively responsive to code com binations of electrical impulses; and means selectively controlled by a single reception of a predetermined codev combination to cause a plurality of spacing operations of said spacing mechanism.

2. The combination as set forth in claim 1 in which said printing mechanism embodies a carriage shift mechanism and said selectively controlled means is operable only when said shift mechanism is in actuated position.

. 3. The combination as set forth in claim 1 in which said selectively controlled means comprises means for predetermining the number of operations of said spacing mechanism which will occur at a given position of said carriage.

4. The combination as set forth in claim 1 in which said means comprises a notched plate and a series of stops insertable into said notches, said plate and stops being movable into position to stop spacing movement of the carriage at predetermined points in response to said last mentioned code combination of impulses.
