formation, such as for example, prices and trol circuits associated therewith and extending ranges of stocks, bonds and the like, in columns or in tabulated form to enable the ready reading and comparison thereof. Heretofore the usual manner of spacing the printing unitfrom one column to the next was for the transmitting operator to transmit the proper number of word spacing signals by successively actuating the .word space keylever, the printing unit moving 7 Another still further object of the invention resides in the ease with which it may be attached to printers of various types. 7

These and other objects and features of the invention will be more fully understood from the following detailed description thereof when a pilot printer so as to cease transmitting further word space signals when the printing unit is opposite the beginning of the next column. This arrangement places somewhat of a burden on the transmitting operator and while. being susceptible to error, also has the disadvantage of being likely to consume more line time in spacing the printing unit from one column to another than is absolutely necessary.

, Accordingly, it is one of the primary objects r of the present invention to provide an attachment for page type telegraph printers so that after completing the printing in one column, the printing unit may be automatically moved relative to the printing platen to stop in a predetermined stop position at the beginning of the 3 next column.

' In accordance with the above object it is. a still further object of the invention to provide a transmitting arrangement for transmitting the necessary number of word space signals to move Another still further object of the invention is to provide an improved and simplified keyboard mechanism. r

A still further object of the invention resides in its simplicity and the mininum number of parts required to accomplish the above objects.

taken in conjunction, with 'the accompanying drawing which shows perspectively and diagrammatically the cooperating elements of a page printer and a keyboard together with the contherebetween for accomplishing the above objects. Intaccordance withthe invention a notched bar pivotally supported atits ends in .the printer extends across the samefparallelto the direction of travel of the printing unit and has removably placed thereon aseries of. stops held in place by the notches 0n the bar. These stops are engageable with the printing unit at pointsin its travel determined by the location of the stops, to cause the notched bar to rock a slight amount about its ends. The transmitting gmechanismassociated with the printer is one vofthe usual keyboard type and has. a special keyleverwhich when ac tuated closes a circuit and causes the transmission of successive word space signals until the above mentioned circuitis opened by the rocking of the notched .bar. The opening of the circuit stopsthe transmission of further word space signals and the printing unit will .be in position .to print the first character of a column. When the printing in this particular column is completed. the special key lever is again actuated and word space signals transmitted until the control circuit is again opened by the rocking of the notched .bar. on the printer by the printing unit. I i

In the drawing, elements of a page printer are shown which may be for example those of a stationary platen page printer of the type disclosed in a copending application of J. W. Long et al.,

Serial No. 299,672, filed September 13, 1938, with only those elements of the printer. being shown as are, thought necessary for a thorough understanding of the invention. Although elements of this particular type of printer are shown it will be obvious hereinafterthat the principles of the invention could equally well be applied to practically any of the well known types of page printers, including those employing platens which are movable relative to the printing units, this particular one being chosen merely for the purpose of illustration.

As fully described in the above mentioned copending application the printer comprises left and right hand vertical mounting plates II and I2 respectively betweenwhich is. mounted the printing mechanism of the associated printer. Extending horizontally between the vertical on the recording paper "5.

plates II and I2 is a platen roller shaft I3 upon which is mounted for rotation therewith the printing platen l4. The recording paper l6 passes around the printing platen l4 and is held in frictional engagement therewith by pressure rollers (not shown) so that when the platen shaft [3 is rotated or stepped in accordance with predetermined functions of the printer, the recording paper I6 is advanced, the platen shaft I3 being rotated on each operation an amount suflicient to advance the paper [6 a distance equal to that between two successive lines of print on the recording paper. The printing unit of the printer comprises a type wheel I! mounted at the upper end of a substantially vertical typewheel shaft IS. The typewheel shaft is carried in a typewheel car, indicated in general by reference numeral [9, which is slidable back and forth in a horizontal plane on horizontal rods 28 and 2| extending between the vertical plates II and I2. The printing operation is performed by moving a squared rod 22 toward the front which through a lever 23 on the typewheel car i9 causes the typewheel to be pressed against the recording paper l6 and platen 14. The typewheel car I9 is advanced from left to right in successive steps, the steps being in conjunction with each printing operation or during word spacing operations in which no printing operation is performed. The typewheel car I9 is returned for the beginning of a new line of print in one continuous movement in response to a typewheel car return signal or it may be accomplished automatically in conjunction with a line feed operation.

In accordance with the invention two trunnion screws 24 and 26 mounted horizontally in the vertical plates II and [2 respectively, pivotally support a notched bar 21 therebetween. The notched bar 21 has a series ofnotches such as 28 along the upper'surface thereof and carried on the bar 21 are a series of movable stops 29 which are held in place along the length of the bar by the notches 28 therein. The stops 29 are placed on the bar 21 at the points where it is desired to begin the printing of a column and the number of such stops on the bar will usually determine the number of columns exclusive of the first column that will be printed The stops 29 have extending horizontally from the rear thereof arms 3| which are normally in the path of a depending projection 32 of the typewheel car l9. As the typewheel car l9 moves across the paper 16, the depending projection 32 engages the arms 3| on the stops 29 and causes the bar 21 to pivot a slight amount in a clockwise direction when the typewheel car reaches a point opposite the stops. Fixed adjacent the left hand end of the bar 21 is a depending arm 33 which cooperates with the tongue 34 of a normally closed spring contact 36 to cause the contact to open when the bar 2'! pivots in a clockwise direction as hereinbefore described. As the projection 32 of the typewheel car 19 moves out of engagement with the arm 3| on one of the stops 29, the tongue 34 of the contact 36 causes the bar 21 to pivot back into its normal position. The manner in which the contact 36 controls the movement of the typewheel car I9 so as to permit -the recording in columns will hereinafter be described in conjunction with the description of an associated keyboard.

vention while being somewhat of the usual construction in that it employs a plurality of keylevers which are operated one at a time to cause the transmission of a representative group of impulses has certain advantages thereover which will be hereinafter described. Only one character keylever 31 and the word space keylever 38 are shown, there being the usual number of other character keylevers similar to 31, only the one being shown for the sake of clearness. Located beneath the keylevers 31 and 38 and extending transversely thereof in the usual manner are a set of five permutation bars 39. The permutation bars 39 have extending from their upper sides beveled surfaces 4| which are adapted to cooperate with the lower edges of the keylevers when actuated and cause the permutation bars to be moved in the directions of their length in various combinations, which are representative of the keylevers actuated in a manner well known in the art.

In operative relation with the right hand end of the permutation bars 39 are a series of five sets of spring contacts 42, one individual to each of the permutation bars. When one of the permutation bars 39 is in its left hand position the associated contact 42 is allowed to open, and with the permutation bar in its right hand position the associated contact 42 is closed. Thus the contacts 42 are positioned in opened and closed conditions in accordance with the position of the permutation bars 39, which in turn are positioned in accordance with an operated keylever, such as 31. One of the springs of each of the sets of contacts 42 are connected in multiple by conductors 43 to potential, and the other springs of the contacts 42 are individually connected by individual conductors such as 44 to segments numbered I to 5 of a segmented ring 46. The segmented ring 46 comprises one of the four rings of a start-stop type distributor indicated in general by reference numeral 45, the operation of which will hereinafter be described.

The keylevers, such as 31 and 38, are pivotally mounted adjacent their rear ends of a rod 41, and springs such as 48 hold the forward ends of the keylevers in their normal elevated position. A universal bail 49 pivoted at 5| is held by a spring 52 in engagement with the undersides of each of the keylevers, such as 31 and 38, and is adapted to pivot a slight amount in a counterclockwise direction each time any one of the keylevers is actuated. A normally opened contact 53 has the tongue thereof associated with the universal bail 49 and is adapted to be closed by the pivoting of the universal bail. One side of the contact 53 has potential connected thereto and the other is connected by conductors 54 and 56 to the tongue of a relay 5!. The backstop of the tongue of relay 51 is connected by a conductor 58 through the coil of a magnet 59 to ground. Thus each time the universal bail is operated .to close the contact 53, potential is applied over the above described circuit and through the coil of the magnet 59 to ground, to energize the same. The magnet 59 is the start magnet of the start-stop distributor 45 and has an associated spring biased armature 6|, which when operated releases brushes 62 and 63 for movement over their associated rings. The brush 62 bridges the segmented ring 46 with an associated solid ring 64 and the brush 63 bridges rings 66 and 61.

The solid ring 64 of the start-stop distributor 45 is connected by a conductor 68 through the coil of the selector magnet represented at 69 of theabove describedprinter. to control the same in accordance with the operation of the keyboard. This circuit. may be extended by a conductor such as H through the coils of other printer controlling selector magnets such as 12 or it may be connected to operate a relay which in turn may control a number of page type printers. A segment '13 of the segmented ring 46 is connected to potential and in the stop position of the brush 62 this segment is bridged with the solid ring 64 and hence a closed line condition is maintained on the conductors such as 68 and II for the stop or rest position of the distributor 45. In the stop position of the distributor the brush 63 bridges the solid ring 61 which has potential connected thereto with an open segment 14 of the ring 66. Another segment 65 of the ring 66 is connected by a conductor 76 through the coil of a lock magnet 11 over a conductor 18 and through the coil of the relay to ground. A resistance 86 is connected between the conductors 18 and 56 for reasons hereinafter described. As the brush 63 is on the open segment 74 in the stop position of the distributor, the circuit through the magnet and relay 51 is not completed and hence for this condition this relay and magnet remain unoperated. The armature 19 associated. with the magnet 11 is fixed to. a substantially horizontal lever 8| which is pivoted on a pin 82 at its right hand end and has a vertical wedgeshaped portion 83 at its left hand end. The lower edge of the wedge-shaped portion 83 is adapted to cooperate with upwardly extending vertical projections 84- adjacent the right hand ends of the permutation bars 39 to lock the same in operated positions as will be hereinafter described. A spring 86 attached to the lever 8| normally holds the lower edge of the wedgeshaped portion 83 above and out of operative relation with the projections 84 on the permutation bars.

The normaloperation of the distributor 45 is as follows, assuming that one of the keylevers such as 31 is operated and. subsequently released, the operation of'which as' described selectively positions the permutation bars 39 and contacts 42 and during the last part of the operation thereof actuates the universal bail 49 to close the contact 53. The closing of the contact 53 completes the circuit described to the start magnet 59 of the distributor 45 and releases the brushes 62 and 63 for rotation. As the brush 62 leaves the segment 73 of the ring 46, it contacts an open segment 87 and thus an open line condition is established over the conductor 68 which is the start impulse of the following code group of impulses to be transmitted. The contacts 42 supply potential to the segments numbered to 5 of the ring 46in a combination representative of the position of the permutation bars 4| and as the brush subsequently traverses these segments, a group of impulses composed of open and closed line conditionsis transmitted over the conductor 68. As the brush 63 moving with the brush 62 leaves the open segment 14 of the ring 66, it connects potential from the solid ring 6'! to the'segment 65 and thence over conductor 15 through the coil of the magnet 11, conductor 18 and through the coil of relay 51 to ground. This causes the magnet 11 and relay 51 to operate and as the magnet 11 operates, the wedge-shaped portion 83 of the lever 8| is brought down to be positioned-either to the right tongue of a normally open contact 92.

or left. ofthe projections 84 on the permutation bars 4|, to prevent the position thereof from being changed until the wedge-shaped portion is elevated to its normal position near the completion of one revolution of the brush 63 when it contacts the open segment 14 to open the circuit through the magnet 11 andrelay 51. The operation of the relay 51 opens the circuit from the contact 53 to the start magnet 59 and as this occurs relatively early in the revolution of the brush 63, the armature 6| of the magnet 59 will have sufficient time to return to its unoperated position and stop the brushes 62 and 63 after they have made one revolution. Thus the operations of the magnet 11 prevents the operation of another. keylever such as 31 during the transmission of a code combination representative of the previously actuated keylever and the operation of the relay 51 insures that the circuit to the start magnet 59 is normally opened relatively early in the cycle of operation of the distributor 45 and normally prevents more than one revolution of the brushes 62 and 63, should one of the keylevers such as 31 not be released until near the end of a revolution of the brushes. Should one of the keylevers such as 31 be held depressed for a prolonged interval the resistance 88 around the coil of therelay .51 permits suflicient current to flow therethrough to keep the relay operated and thus maintain the circuit to the start magnet 59 open. 7

In accordance with the invention a special keylever 88 is employed which is hereinafter referred to as the tabulating keylever. The tabulating keylever 88 is pivoted on the rod 41 and is positioned to the left of the permutation bars 39 so that on theactuation thereof, it does not cooperate directly with any of the beveled surfaces 4| on the permutation bars 39. The tabulating keylever 88 has therein and extending at right angles thereto a rod 89, the right hand end of which extends above the word space keylever 38. The left hand end of the rod 89 carries an insulating member 9| which cooperates with the Thus when the tabulating keylever 88 is operated, the rod therein causes the word space keylever 38 to operate and position the permutation bars 39 in a combination representative thereof and also close the contact 92. The manner in which such an operation'of the tab-ulating keylever 88 permits successive word space signals to be automatically transmitted-will be hereinafter pointed out.

One of the terminals of the contact v92 is connected by a conductor 93 to one of the terminals of the normally closed contact 36 hereinbeiore described on the associated printer. The other terminal of the contact 38 is connected by a conductor 94 to the conductor 58 while the other terminal of the contact 92 is connected by a conductor 96 to the conductor 56. Although the printer such as that employing the printing unit l9 is usually directly associated with the controlling keyboard, and a common motor employed to furnish power for operating the printer and rotating-the start-stop distributor 45,- the two units may be separated and operate as independent units, as the only connection necessary between the keyboard and the printer is that established by the two conductors 94 and 96 and a circuit to the selector magnet such as 69.

Assume that a few characters have been print- ,ed at the beginning of a line and it is desired for the next character printed to appear at the,

beginning of a column at a predetermined point in the travel of the typewheel car l9. Accordingly, the first removable stop 29 will be placed opposite the point where the first printed character of a column is to appear. To automatically space the typewheel car [9 from the last printed character to a point at the beginning of the first column, the tabulating keylever 8B is depressed and held depressed until the typewheel car reaches this position whereupon further movement of the typewheel car automatically ceases. The depressing of the tabulating keylever 98 through the word space keylever 38 operating therewith positions the permutation bars 39 so that a word space signal is transmitted as hereinbefore described and also closes the contact 92 which will apply battery through the contact 53, the contact 53 being closed at the time by the universal bail 49 operated by the keylever 38, over conductors 54 and 96, through the contact 92, over conductor 93, through the contact 36 and over conductors 94 and 58, through the coil of the start magnet 59 to ground. This circuit energizes the magnet 59 and maintains the armature 6| thereof in an operated position as long as the keylever 88 is held operated or until the depending projection 32 on the typewheel car l9 engages the arm 3| on the first stop 29 to pivot the bar 21 to open the contact 36\.and break the circuit therethrough as hereinbefore described. This breaking of the circuit to the magnet 59 allows the same to become deenergized and the armature 6| thereof to be positioned to stop the brushes 62 and 63 in their normal position after their current revolution. Thus the typewheel car I9 is advanced from the last printed character on the page to some predetermined point in its travel determined by the position of the next stop 29 on the bar 21. Several stops such as 29 may be placed on the bar 21 and each determines the beginning of a column in the manner above described.

After the typewheel car I9 is automatically stopped in a predetermined stop position at the beginning of a column by the projection 32 engaging the arm 3l of the associated stop 29, to open the control circuit as hereinbefore described, the next movement of the typewheel car in a letter or word spacing direction in conjunction with the printing or word spacing operation disengages the projection 32 with the arm 3| on the stop and allows the bar 21 to pivot back into its normal position. Thus when it is desired to omit the printing in a particular column after the typewheel car l9 has been stepped opposite the beginning of that column, the tabulating key. 88 is again depressed and word space signals will be automatically transmitted as long as the keylever is held depressed or until the projection 32 engages the arm 3| on the next stop 29.

It will be obvious that Where the printers of an entire system, such as those on a news system, are to be controlled in accordance with the above to facilitate the printing in column, only one of the printers, such as a pilot printer associated with the keyboard, need be equipped with the pivotable bar 21 and the stops 29 as the word space signals automatically transmitted from the keyboard will advance the printing units relative to the platens of all the printers on the system.

When a full line of printer matter is being recorded, or at times when it is not desired to print in columns, the engagement of projection 32 with the arms 3i of the stop 29 does not complete the above described circuit to the distribution start magnet 59 as the circuit thereto will be open at the normally open contact 92. Thus the stops 29 have no effect on the movement of the typewheel car l9 during the printing of full lines.

If for some reason it is desired to transmit a number of word space signals and not have them cease when the printing unit is opposite predetermined points on the recording paper all that is necessary is to shunt out the contact 36. Thereupon the keyboard will transmit Word space signals as long as the tabulating keylever 88 is held operated. Although the described use of the tabulating keylever 88 is to cause the transmission of word space signals it could easily be adapted to cause the transmission of a successionof any of the other signals, such as those representing periods, by an obvious arrangement. By omitting the tabulating keylever 88 and its associated circuits the keyboard would operate to transmit a code signal representative of an actuated one of the keylever as in the standard keyboards.

It will also be obvious, of course, that various other modifications of the invention may be made without departing from the spirit or essential attributes thereof and it is desired, therefore, that only such limitations be placed thereon as are imposed by the prior art or are specifically set forth in the appended claims.
