type Corporation, Chicago,
Delaware Ill., assignor to Tele- 111., a corporation of Application December 31, 1935, Serial No. 56,919 Renewed June 5, 1939 50 Claims. (Cl. 178-25) The present invention relates to printing telegraph systems and apparatus.
Objects of the present invention are to provide, in a remotely controlled telegraph printing machine, apparaus for determining the phase relationship of the printing platen, and means for automatically and selectively ejecting lengths of printing material and for thereafter severing the ejected length of said material from a stock or supply roll.
Another object of the invention is to provide means at a remote station operative in response to an inquiring signal for informing a transmitting station of its receptive condition.
A further object is to provide means at a remote station selectively responsive to a received signal for operating a keylever thereat to initiate the transmission of a signal indicative of a particular condition.
A still furtherobject of provide means whereby the mitting station may have complete control over the apparatus at a receiving station, so that at the receiving station may be conditioned by the sending operator either for receiving or sending messages.
To achieve the above and other objects of the invention, a page printerof the type disclosed in U. S. Patent 1,904,164 is arranged with means for determining the synchronization or phasing of the platens of the interconnected printers, as well as means for feeding a predetermined length of record material through a printing appathe invention is to operator at a transratus and for cutting offi the predetermined length of material automatically. This arrangement is desirable in systems wherein the printing apparatus at the receiving stations remain unattended except for the tearing off the copy, or for attention when the attendant is signalled. The present invention thus provides means whereby the sending operator can determine periodically whether or not the platen of the receiving printer is in exact phased relation with the platen of the sending machine.
Specifically, one embodiment of the invention contemplates the provision of. a cam, mounted on the platen shaft and rotatable therewith, which cooperates through a lever arrangement with a special selectable function lever. This function lever is further provided with a forward extension which cooperates with a keylever, so that upon the selection of the special function lever, a keylever of the keyboard is actuated and the transmitter is operated to transmit to the sending station impulses indicative of a crates the send-receive particular condition which notifies the sending operator that the receiving printer is operating correctly. Simmltaneously with the actuation of the keylever, the special function lever also opbreak switch to change the conditioner the receiving apparatus from receiving tosending.
Thus, when the special function lever is selected, it performs two functions, first the operation of the send-receive break key, and secondly the operation of a keylever of the keyboard to transmit an answer-back signal to the sending operator. However, the special function lever is not selected, even though the selectbe set for its selection, unless the platen and its phasing cam predetermined position; When the phasing cam is not in a predetermined position, the selection of the special function lever is prevented and no signal is transmitted, thus indicating to the sending operator, by the failure to receive a response, that the platen of the receiving printer is not in phase with that of the sending or home printer. By the arrangement according to the present invention, a positive signal or indication is transmitted to the sending operator to apprise him of the fact that the platens of the interconnected printers are in phase.
Another feature of the invention resides in the automatic mechamsm for severing the record material in predetermined lengths, so as to provide tickets or coupons of predetermined size. Also, multiple copies of such tickets or coupons are produced. According to the embodiment disclosed, any one or more of four rolls of record material may be fed into the printing area under the control of the remote sending apparatus by selecting in the receiving apparatus special function levers according to thenumber of copies desired. These special function levers control the release of clutch mechanisms to govern the feeding of the record material to the printing zone. After the record material has been so fed, the line feed mechanism of the receiving apparatu's, which has been rendered inoperative during the latter operation, has again been rendered operative to feed the record material line by line until a predetermined length of coupon has been obtained, whereupon theleading edge of the record material acts to establish an electrical circuit for operating automatically the mechanism for severing the coupons, simultaieously with which the coupons are ejected by constantly rotating ejector rollers.
A more comprehensive understanding of the present invention may be had I a description, taken in conjunction the f companying drawings wherein like re. characters represent similar parts througfh the several views.

The shaft 23 is nisrn which is associated with the base portion not shown, 27 comprises a bracket 3! which is fixed to the base portion and consists primarily of three elecing. The latter changeover or switching mechanism is one of the salient features of the present invention.
Contact pair 32 is located in the signal line and is used as a break contact therein. For example, having reference to Fig. 4,'it is observed that contact pair 32 is in the circuit extending from battery 36, conductor 31, contact 38 of the transmitter contacts, conductors 39 and 4!, contacts 32 (when closed), relay 42, line wire 43 to the receiving station, thence over a similar circuit at the latter station. Contact pair 33 is so wired as to shunt the sending contacts 2| of the keyboard transmitter, thereby rendering the keyboard ineffective. From Fig. 4 it is obvious that the contact pair 33 is in the circuit extending from battery 36, conductor 31, contact 38, conductor 39, contact 33, and conductor 44 back to battery. Contact 34 ,is so connected that it may be placed in the circuit of the control magnet 45 of a tape transmitting distributor.
Lever arm 36, Fig. 3, by which that part of the break mechanism which is located on the base portion 2? may be manually operated, can occupy any one of three positions. The intermediate position of this lever arm is illustrated in Fig. 1 and 'is called the "receive position; the uppermost position is known as the break position, and the lowermost position (which is shown in Fig. 3), is the send position. When the lever arm 33 is in the send position, contact pair 32 in the line circuit is closed; contact pair 33, shunting the keyboard transmitting contacts is open; and contact pair 34 in the tape transmitter distributor circuit is closed. When lever arm 38 is in the receive position, contact pair 32 in the line circuit is still closed; contact pair 33 shunting the keyboard contacts 2! is also closed; and contact pair 34 in the tape transmitter distributor circuit is open. In the extreme upward position or" lever arm 36, known as the break position. contact pair 32 in the line circuit is opened, thereby breaking the line circuit, and contact pairs 33 and 34 are closed and opened respectively.
Besides being movable manually to each of the'three aforementioned positions, lever arm 30 may also be moved automatically from the send to the receive position and vice versa by means of two systems of levers, mechanically operated, in the printing unit. The send-receive break mechanism is shifted mechanically from the send position to the receive position by means of the system of levers including lever 23 (Fig. 3). As indicated in Figs. 1 and 3, a lever 35 is pivoted at 45 upon the rear wall of a bracket 3| and is of substantially T-shaped configuration comprising arms 46, 41, and 43. Arm 4'! is provided with a laterally disposed portion 49 which coacts with lever 29, while vertical arm 48 is provided with a laterally disposed arm 5| which actuates contact switch 32. Arm 46 of lever 35 is provided with alaterally disposed portion 52 to which is attached one end'of a spring 53, the other end of which is fixed to bracket 3|. Arm 46 is also provided with a two-position or double shouldered notch 54 to cooperate with an'arm 55 of 'a lever 56 when lever arm 46 is moved either to its send or receive position. Appropriately positioned below lever 35 and pivotally connected at 51 to bracket 3| is the threearm lever 56. Arm 58 of lever 56 cooperates with lever arm 36 and arm 59 is provided with a laterally disposed portion 6| which actuates blades 62 and 63 of contact pairs 33 and 34. To portion 6| is fastened one end of a spring 64, the other end of which is anchored upon bracket 3|.
In the illustrated position of lever 35, the line contact 32 remains closed so that the signals coming in over the line can actuate the line relay 42 and hence selector magnet 65 (Fig.4), and the contact pair 33 is also closed to render the keyboard transmitter inoperative by shunting the transmitting contacts 2|. This position is attained, as set forth in Patent 1,904,164, by the operation of lever 29 (Fig. 3), in a counterclockwise direction upon the reception of two successive identical code signals, which imparts clockwise rotation to lever 35 about its pivot 45 sufficient to permit the arm 55 of lever 56 to escape the left or deeper portion of notch 54. Lever 56 thereupon is rotated slightly in a clockwise direction under the influence of spring 64 to bring arm 55 into engagement with the righthand portion of notch 54. This movement of lever 56 effects through portion 6| and contact spring '62 the closure of contact pair 33 and opening of contact pair 34. By the rotation of lever 35, arm 48 thereof has not moved sufiiciently to open the signal line'contacts 32. Lever 35 is shown in Fig. 3 in the send position; that is, in a proper position to permit the transmission of signals from keyboard II. This positionis attained automatically in a manner which will now be described.
Lever 56 of the send-receive break mechanism is provided with an extension 66 which cooperates with one arm of a lever 61 pivotally supported on a bracket 68 mounted on the 'base portion 21 of the unit. The other arm of lever 61 cooperates with a screw 69 adjustably carried in the forwardly extending arm (Fig. 2) of a special function lever 12 pivotally mounted on function lever shaft 13. Function lever 12 nor.- mally tends to rotate in a counter-clockwise direction (as viewed in Fig. 2) under the influence of a spring 14 individual thereto, into selective relation with a seriesof selector vanes 15, but is held against rotation by a function lever bail 16, except during the cyclical operation of the apparatus, as set forth in Patent 1,904,164.
At the forward end of arm H there is carried an adjustment screw 11 which cooperates with one of the keylevers l3, so that when the function lever 12 is selectively operated upon the proper setting of selector vanes 15, the keylever |3 associated therewith will be depressed through the instrumentalityof screw 11. Function lever 12 is" also provided with a ri-ghtwardly extending arm 18 (as viewed in Fig. 2) which cooperates with the end 19 of the depending arm of a bell crank lever 8| .(Fig; 1) pivoted to a bracket 82 mounted on a portion 83 of the printer frame. The end of the horizontal arm of bell crank lever BI is pivoted to one end of a vertically dis posed link 84, the upper end of which is pivoted to arm 85 (Fig. 2) of a lever 86 carried on a pivot shaft 81 disposed between brackets 88 and 89 appropriately supported in the apparatus. Lever 83 is also provided with an arm 9| at the extremity of which is carried a cam follower roller 92 which, due to the action of a spring 99, coacts with a platen phasing cam 93 fixed to a shaft 34 on which a platen 95 is carried.
When the cam follower 92 rests in the depression in the periphery of cam 33, the function lever I2, when selected for operation upon the reception of an allotted code signal, will be enabled to initiate the transmission of a code signal indicative of this fact to the operator at the inquiring station. Where printed forms are employed, it is essential that they be correspondingly positioned in the interconnected printers. To determine this, it is prearranged that the printed forms be placed in the printer in a definite position with respect to the depression in cam 93, so that when the follower rollers e2 at the interconnected stations rest in the depressions of their respective cams 93, the printed forms in each printer will be correspondingly positioned. Thus, when the sending operator observes that the cam 92 of his printer rests in the depression of cam 93, he may operate a certain one of his keylevers which has allotted thereto a code combination corresponding to that to which the function lever I2 responds. Upon the reception of this code signal at the receiving station, the selector vanes 15 will be positioned permutably in a manner set forth in Patent 1,904,- 164, and as the function lever bail I6, Fig. 2, is oscillated, the spring I4 will draw the function lever I2 towards the vanes I5. Since the vanes are set to cor-respond to the code out on the edge of the function lever I2, the function lever I2 will be rotated sufiiciently to depress keylever I3 through screw I7, and to transmit a signal to the sending operator to apprise him that the platen of the receiving printer is in phase with the platen of the printer at the transmitting station.
In the event that the cam follower 92 is not found resting in the depression in cam 93; that is, if the platen and hence the printed forms, are not in proper position or phase, the follower roller 52 will dwell on the high part of cam 93, thereby causing lever SI to assume its counterclockwise position, thus raising link 84, rotating lever 8I counterclockwise (as viewed in Fig. 1) to bring the end 19 thereof into the path of arm I8 of function lever I2, thus blocking its selection and preventing the function lever 12 from responding to the selective disposition of the selector vanes I5. Accordingly, the keylever I3 will not be depressed and. no code signal will be transmitted from the receiving station to the sending operator. It is thus seen that if the platens of the interconnected printers are in phase, an answer-back signal indicative thereof will be automatically transmitted by the receiving sation in response to an inquiring signal sent by the sending operator, and if the platens are out of phase, lever 8| will block the selection of function lever I2 and no answer-back signal will be transmitted.
As previously indicated, the send-receive break mechanism has to be properly conditioned to permit the transmission of the signal indicative of phased platens. From the disclosure in Patent 1,904,164 it may be observed that a sending operator may condition an interconnected telegraph apparatus for receiving by transmitting thereto two blank signals (that is, two code signal combinations composed entirely of spacing impulses) which will, through the instrumentality of lever 29, place lever 35 in the position shown in Fig. 1, in which condition the keyboard contacts 2I are shunted. Now in order that the sending operator may receive in response to his inquiry a signal indicating to him that the platens are in phase, he must be able to control remotely the receiving apparatus so as to condition it to transmit signals; that is, he must open contacts 33 to break the shunt circuit of contacts 2I. To accomplish this result, the screw 69 carried by arm 'II of function lever I2, upon the selective operation of lever I2, effects the clockwise rotation of lever 61 which in turn causes the lever 53 to rotate sufliciently in a counterclockwise direction to cause arm 55 thereof to engage the deep portion of notch 54 (as shown in Fig. 3) and to move arm BI away from the contact spring 62, whereupon contact 33 will open to break the shunt circuit. Simultaneously with the operation of lever 61, as was previously noted, the keylever I3 associated with function lever I2 was depressed, which actuated the selector bars I6 permutably to impart through latches I! a corresponding setting to contact levers I8, and also the universal bar 96 to initiate the rotion of the transmitting cams 22, whereupon the desired indicatory signal is transmitted over the signal line 43 (Fig. 4) to the sending operators station.
In addition to the feature of determining the phasing of the platens of interconnected printers, the present invention also provides, as illustrated in Figs. 5 to 11, a severing and ejecting mechanism for the printed forms and a multiple paper feeding mechanism which is solely under the control of the sending operator at a remotely situated station. The arrangement herein disclosed provides for feeding either simultaneously, permutably, or individually one to four copies of record material to the printing zone. The record material may be provided with suitable duplicating means, such as carbonized back, or spot-glued carbon paper. In Fig. 5 is shown the selectively operable clutch release mechanism for the several feed rolls. A predetermined setting of the selector vanes I5 will result in the selection of a special function lever IUI, which, upon the rocking of function bail 76 about shaft I52, will respond to the action of its spring I03 to rotate a certain extent in a counterclockwise direction about the function lever shaft I3, thus causing the tail portion IE4 to rise, bringing push bar I55 superposed thereabove into the path of the func tion bail blade Hi3. Thereafter as function cam I01 rotates on shaft I88, a spring I99 causes blade I56 to move rightwardly and it in turn imparts like movement to push bar I which imparts clockwise rotation to a bell crank III pivoted on shaft H2, thereby actuating a vertical trip bar I I3 downwardly. Bar H3 acts upon a clutch release bell crank I I 4 to cause its disengagement from 'a stop disc II5 fixed to feed roll shaft H6, which shaft thereupon is free to make one complete revolution, thus feeding a predetermined portion of record material II? (Figs. 5 and 6) from supply roll I I8.
Push bars I25, I22, and I23 may be brought into operative relation with function lever blade Hi5 either simultaneously or individually, depending upon whether a common function lever or individual function levers are employed, to operate cell cranks I 24, I25, and I26, which in turn through vertical trip bars I21, I28, and I29 operate clutch release bell cranks I3I, I32, and
I33 to feed record material from rolls I34, I35, and I36, respectively. As the function bail 15 is returned to its normal position by cam I81, the push bars I85, I2I, I22, and I23 are restored to their leftward positions by their individual springs I36. 7
Although line feeding of the printed record is performed in the same manner as set forth in Patent 1,904,164, the feeding of the record material to the printing zone preparatory to printing and cutting a new ticket or coupon is done by power derived from a motor I4I appropriately mounted on the frame I42 (Fig. 7) of the apparatus. The positional relationship of the elements comprising the features of invention herein described, with respect to the structure disclosed in Patent 1,904,164, is indicated in Figs. 6 and '7, having reference to the drum I58 of the carriage return mechanism carried on bracket I60 of the main frame. These parts correspond with parts 223 and 22I, respectively, shown in Fig. 6 of Patent 1,904,164. Fixed to the motor shaft I43 is a pinion I44 which through a gear I45 imparts power to a shaft I46 which drives gears I48 individual to each of the feed rolls I49. Gears I48 are connected to the shafts carrying the feed rolls I49 by friction discs II (Fig. 7). The ejector rollers I52 and I53 are also rotated by motor I4I through a frictional connection with gear I54 meshed with a pinion I55 carried on a power take-off shaft I53 (Fig. 6) which is rotated by gear I48 through gear I51.
In view of the similarity of the feeding mechanisms associated with rills II 8, I34, I35, and I36, it is necessary that only the arrangement associated with one of the mechanisms (roll II8) will be described in detail. The record material from roll 'I I8 passes between guide plate I58 and guide roller I59, thence between feed roller I49 and pressure roller I6I Which'protrudes through an aperature in plate I58. The assembly of the pressure rollers 8! for the several feed rollers I49 is shown in Fig. 9, and will be discussed hereinafter. The record material I I1 then passes between a lowermost portion of guide plate I58 and a guide plate I52 and thence between guide plate I62 and a bottom plate I63 to the opening or shearing edge I944. The edge of the bottom plate I63 at the opening I64 coacts with a shear blade I65 (Fig. '1) to sever the record material. 'The record material is guided to the platen 95, carried on platen shaft 94, by guide plate I68 to the printing zone indicated by type bar I61, Fig. 6, thence between guide plates I 66 and I68 to the ejector rollers I52 and I53.
A pressure roller I69 (Figs, 6 and 9) cooperates with the platen 95 for the purpose of line feeding the record material during printing. Roller I69 is rotatably supported at one end by one arm of a three-armed. lever I1I (Fig. 6) fixedly -mounted on a shaft I12, and at the other end by a' bell crank lever I13 (Fig. 9) also fixed to shaft I12. Pressure is imparted by roller I69 upon platen 95 through the instrumentality of springs I14 and I associated with levers HI and I13, respectively. Line feeding is accomplished as set forth in Patent 1,904,164 through the instrumentality of a line feed. bell crank lever I16 (Fig. 9), which is analogous to lever 251 shown in Fig. '7 of the patent. As stated in the noted patent, theoperation or function of line feeding is initiated by the reception of a special code signal which acts through the selector mechanism to select a line'feed function lever Which controls the operation of line feed core I88 of a solenoid I89.
link lllwhich rocks lever I16 counterclockwise about its pivot I18 to step a feed pawl I19 along the periphery of ratchet wheel I8! fixed to platen 95 so that a downward movement of link I11 will effect the rotation of platen 95 one angular step in the direction of the arrow.
Shear blade I65 forms one arm of a shearing lever I82 pivoted at I83 (Fig. 7) the other arm I84 of which is articulated to a lever I85 (more clearly shown in Fig. 6) pivotally anchored at I86. Lever I85 is pivoted atv I81 to the vertically movable Arm I84 adjacent lever I'll, is provided with a hook I9I adapted to cooperate with arm I92 of lever I'll so that upon the upward movement of hook I9! (due to the clockwise rotation of lever I82, Fig. 7, by solenoid I89), lever I1I will be rotated counterclockwise (as viewed in Fig. 6) until arm I93 thereof becomes latched by lever I94 pivoted at I95. This action of hook I9I upon lever I1I causes the removal of pressure roller I69 from platen 95 to permit the feeding of record material from rollers H8, etc., as will presently appear. 7
The unlatching of lever I1I is achieved in the following manner. Lever I94 is pivotally connected to a link I 95 which is connected to a U-shaped bail I91 pivoted, as indicated in Figs. '7 and 9, on a shaft I98. Portion I99 of bail I9! is provided on its bottom edge with a series of cam projections 28I, Fig. l, which cooperate with a corresponding series of cams 282, one associated with each of the feed rollers I49. Whenever a cam projection 283 on a cam 282 passes under a cam projection 28I, the U-shaped lever I91 is rotated in a counterclockwise direction (as viewed in Fig. 7) and as portion I99 thereof is raised, like motion is imparted to link I96, which in turn rotates lever I94 sufficiently in a counter-clockwise direction against the tension of spring 284 to unlatch lever I1I, whereupon spring I14 is free to press roller I69 against platen 95, thus rendering the line feed mechanism again efiective.
The operating circuit for solenoid I89 is shown diagrammatically in Figv '7 and is controlled by two contracting rings carried on ejector rollers I52 and I53. The rings 285 and 285 normally complete an energizing circuit for a relay 281 which circuit extends from battery 288, through rings 286 and 285, over wire 289, through winding of relay 281, thence to ground. The armature 2 I I of. relay 261 controls an operating circuit for solenoid I89 which circuit extends from battery 2 l 2, through contact 2 I 3 (when closed), armature 2! I, over wire 2M, through the winding of solenoid I89, thence to ground. So long as no record material is interposed between rings 285 and 285 the relay remains energized, and thecircuit for solenoid I89 remains broken, but when the record material which has been advanced by the line feed mechanism reaches the ejector rollers I52 and I53 and is interposed between rings 285 and 285, the circuit for relay 281 is broken, whereupon armature 2 I I is released, and upon responding to its spring 2I5 closes contact 2I3 to establish the energizing circuit for solenoid I89. The solenoid I89 will remain energized until the severed portion of the record material has been completely ejected by rollers I52 and I53, after which rings 285 and 286 will againcorne into contact with each other to effect the energization of relay 281, and thereby break the operating circuit for solenoid I89. It is thus observed that the introduction of the record material between rollers I52 and I53 (and hence between rings 285 and 288) is instrumental in effecting the severance of the record material.
Operation The record material supply rolls IIS, I35, I35, and I36 are appropriately supported in the apparatus, and the recording materials therefrom are guided around their respective guide rollers I53, and between their respective feed rollers I49 and pressure rollers ISI, and their edges are brought into line with cutting edge I54. Upon receipt of a code signal assigned to function lever I05, the vanes will be set correspondingly and upon initiation of operation of the apparatus under control of the selector mechanism, as described in Patent 1,904,164, the function bail 16 will be rocked, permitting lever IGI to be biased by its spring IE3 to cause extension I04 to raise push bars I65, I2I, I22, and I23 into operative relation with function bail blade I 05 so that when these push bars are pushed rightwardly (as viewed in Fig. 5) bell cranks III, I24, I25, and I25 will be rotated clockwise simultaneously to operate, through bars IE3, I21, I23, and I29, clutch release levers II I, I3I', I32, and I33 simultaneously. In this manner, four layers of record material are fed to the printing zone indicated by type bar I61. During this feeding operation, lever I1! (Fig. 6) is latched by lever I94 to hold pressure roller I39 out of engagement with platen 95 to permit free access of the record material therethrough to the printing point. Lever I1I (Fig. 6) and lever I13 (Fig. 9) are fixed to the shaft I12 so that when lever III is operated, lever I13 will also be operated to control through a bar 2H5 a series of levers 2I1 carrying the pressure rollers IEI. The levers I13 and 2I1 are so articulated by slot and pin connection with bar 226 that when pressure roller I69 is free and therefore operatively effective, pressure rollers IBI will be ineffective and vice versa.
Just prior to the end of the aforedescribed feeding cycle the bail lever I91 is operated to unJatc-h lever I1I and to bring pressure roller I69 into action, whereupon in response to successive line feeding operations the record material is advanced toward the constantly rotating ejector rollers I52 and I53. As soon as the ejector rollers are reached and the record material is interposed between the contact rings 265 and 223, the circuit for relay 261 is broken, whereupon the circuit for solenoid I89 is completed and the shearing lever I82 is operated to cause blade I55 to sever the record material. During this latter operation, lever I'iI is rotated by member Ifii into its latched position, thus separating pressure roller I59 from platen 95. lIhe ejector rollers I52 and I54 are then elIective to feed out or eject the coupon or ticket just produced, and the apparatus is thus prepared to receive again the code signal for selecting function lever IfiI.
Modifications In the form of the invention illustrated in Fig. 12, the platen phasing feature is controlled directly by a sword 258 of the sword-and-T selector according to U. S. Patent 1,745,633, and which is also shown in Fig. 28 of U. S. Patent 1,984,164. Briefly, this selector mechanism comprises a receiving magnet 2II responsive to line signal impulses over a signal line 22I which extends, in the present embodiment, through the winding of selector magnet 2I9 to a break contact 222 controlled by a relay 223. As disclosed in the aforementioned patents, a selector drum 224 operates cyclically in response to start-stop code signals and rotates at a speed in synchronism with the speed of code impulsing, carrying thereon a helically arranged series of cams 225 which cooperate sequentially with a corresponding series of selector levers 226 each of which in turn carries in a ball and socket joint a sword 2I8 which is provided with abutments 221 and 228 which cooperate with corresponding abutments 229 and 23I on a selector lever 232 which is oscillated according to the marking or spacing impulses received over signal line 22I.
The selector lever 232 is shown in Fig. 12 in its marking position in which position it causes sword 2I8, upon actuation of selector lever 226 by cam 225, to be rotated clockwise against its lower step 233, thus avoiding the insulation piece 234 of a contact 235. When selector lever 232 assumes its clockwise position in response to a spacing impulse over the line wire, abutment 228 of sword 2I8 will cooperate with 23I to swing sword 2 I8 counterclockwise. against its upperstop 235 into position to collide with contact spring piece 234. Sword 2I8 acts under the influence of spring 23? associated with selector lever 225 to close the contact pair 235 to complete a local circuit from positive battery through resistance 238, contact pair 235, over conductor 239, through operating winding 2M of relay 223, thence over wire 242 to negative battery. Inserted in this circuit last described is a contact 243 which acts to shunt the operating winding 24f of relay 223. Contact 263 is controlled by a platen phasing cam 2M similarly in its efiect to cam 93 shown in Fig. 2.
To determine whether the platens of the interconnected stations are in phase, an operator at the sending station after observing that his platen is in the proper or zero position, transmits a test signal which will operate sword 2I8 to close contact 235 to establish a circuit through operating winding 24I of relay 223. However, if the platen at the receiving station is in proper position with the platen phasing cam 244 acting to close contact 243, the operating winding 2M of relay 223 will not be effective since it will be shunted out by the circuit through contact 243. If the platen is not in proper phase and the cam 224 is not in a position to close contacts 243, the operating winding 24I will be energized, whereupon the armatures 245 and 246 will be operated, the former to open contact 222 to break the line circuit to indicate to the sending operator that the platens are out of phase and simultaneously armature 24 6 will close a contact to 221 to establish abell ringing circuit from p0sitive battery through a manually operated contact 248, armature 246, contact 241, Winding of electric bell 249 to negative battery. At the same time, a locking circuit for relay 223 is established from positive battery through contact 248, armature 246, contact 221, locking winding 25I to negative battery. In this manner, by the ringing of alarm bell 249, the attendant at the receiving station is notified that the apparatus at the local station is in need of attention. To restore the relay 223 to its normal unenergized condition after attending to the alarm, the attendant will manually break contact 248, thereby opening the locking circuit for relay 223, permitting contact 222 to close to establish the line circuit.
It is contemplated to provide, in addition to the number of swords 2I8 corresponding to the elements of the code (for example, five or six if a five-unit or six-unit code is used), an extra sword 218 responsive to the stop signal of a start-stop code. Since the stop signal isv normally of marking nature, the sword 218 corresponding thereto assumes the position indicated in Fig. 12; but when the line circuit is brokenror held open, the condition of; the line during the stop interval is reversed or of spacing nature, whereuponthe extra sword 213 assumes the position against stop 236 (Fig. 12) preparatory to operating contact 235.
Figs. 13, 14, and illustrate additional modifications of platen phasing arrangements according to the present invention which are adapted to the structure disclosed in U. S. Patent 1,904,164. In the modification shown in Figs. 13 and 14, a function lever is selected by the setting of the vanes 15 in response to a predetermined test signal, whereupon the function lever 252 will be biased by its spring 253 about its pivot 254 to cause the rearward extension 255 torotate an intermediate lever 256 about its pivot 251. Lever 256 in turn operatesa lever 258 about its pivot 259 (Fig. 14) in a clockwise direction against the action of a spring 268 to close a contact pair 261 for completing a circuit extending contact 211 in the line circuit 212 which thereby indicates to the operator at the sending station that the platens at the interconnected stations are out of phase. The operation of armature 269 completes simultaneously a bell ringing circuit for bell 213 and a locking circuit for relay 266, the circuit for bell 213 extending from positive battery through a manual break switch armature 269, contact 2'14, winding of bell 213, through resistance 215 to negative battery, and the locking circuit for relay 266 extending from positive battery over armature 269 through contact 214, through locking winding 216, over wire 211, through contact 218, over wire 219 through resistance 261 to negative battery. 7
However, in the event that the platens are in phase, the platen phasing cam 281 will be so positioned as to permit the follower roller 282 to rest in the depression 283, whereupon lever 284 which carries the follower roller 282 will respond to the pull of spring 265 and be rotated in a clockwise direction, thereby moving bar 286 downwardly so that the stud 281 thereon will break or open the contact 218 in the locking circuit of relay 266 and close the contact 288 in the shunt circuit around the operating coil 265 of relay 266. This shunt circuit extends from positive battery, through resistance 262, over conductor 263, contact 261 (when closed momentarily upon the selective operation of function lever 252), contact 238 (when closed by stud 281), conductor 219, through resistance 261 to negative battery. Thus, if the platen 261 of the receiving printer is in its proper position when the test signal is sent over the line, the function lever 252 is selected and contact 261 is closed momentarily (during the cyclic period of operation of the apparatus). The relay 266 is not opersion 283, which permits bar 286, carrying stud 281, to be moved downwardly under tension of spring 285 until contact 218 is opened and contact 288 is closed. Closing contact 268 forms a shunt around the operating coil 265 of relay 266, thus causing the relay 266 to remain unoperated.
In the form of the invention shown in Fig. 15,
depending from arm 299 of a bail lever 381 pivotally carried on a pivot shaft 382 in the frame of the apparatus. Lever 381 is provided with an arm 383 carrying at its extremity a cam follower roller 384 which coacts with a platenphasing cam 385. The platen phasing cam 385 is shown in Fig. 15 in its phased position, in which position the disengagement of lever 294 from bar 298 will have no effect upon either a bell 386 or the signal line 381. In the event that the platen of the receiving printer is not in phase, the projection 3880f phasing cam 385 Will be out of operative engagement with follower roller, 384, permitting lever 381 to be rotated in'a clockwise direction under the action of its spring 389 when shoulder 291 of lever 294 is disengaged from bar 288 in response to the operation of function lever 291 under the control of the remote sending station. When this happens, a contact 311 in the signal line circuit 381 will be opened through the instrumentality of projection 318 on bar 298, thus breaking the'line circuit and indicating to the sending operator that the platens at the interconnected stations are out of phase. At the same time a contact 312 will be closedthrough the instrumentality of a stud 313 on bar 298, thus completing a bell ringing circuit for bell 386, which extends from positive battery through contact 312, resistance 314, winding of bell 386 to negative battery. Accordingly, it is noted that when the platen phasing cam 385 is in the position shown in Fig. 15, the selection of function lever 291 and operation of lever 294 will have no effect upon the platen phasing lever 381 and hence no indication is transmitted over signal line 381 to the sending operator. l
The platen phasing arrangements herein described are particularly applicable to systems employing printed forms. and sprocket feeding arrangements therefor. In the operation of such systems, a telegraph printer using a plurality of printed forms arranged in superimposed relation separated by duplicating means, it is essential that the leaves containing the printed forms be held in accurately alignedrelation to each other so that the entries on the forms be made at their proper places on the forms even though the operation of the printer be continued without attention from an operator for a long period of time. In printing telegraph machines absolute accuracy in the positioning of the printing forms is essential because supervision is not contemplated for the purpose of making adjustments in the relative positions of the several sheets if such adjustments become necessary. If errors occur in aligning the sheets, such errors may even become cumulative; therefore, to prevent such an occurrence, the platen phasing means of the present invention permits the. sending operator to test the interconnected printers to determine whether the platens at each station are in proper phase relationship to each other.
In printers wherein is provided a shift and unshift position for the platen, the platen phasing arrangement is designed to be effective only when the platen is in the upper case position, and then only when the follower roller 232 for example (Fig. 13) rests in the depression in cam 28!. In other words, the platen phasing arrangement will be effective only when the lever 284 (or lever Sill, Fig. 15) assumes its furthest clockwise position. On the other hand, under the following three conditions, the platen phasing arrangement will not be effective, namely (1) when the platen is in the upper case or shift position and the follower roller 282 dwells on the high part of cam 28% (2), when the platen is in the lower case or unshift position and the follower roller 282 rests in the depression in cam 283, and (3) when the platen is in the latter position and the follower roller 232 dwells on the high part of cam 283. It is, of course, understood that although the noted three conditions apply specifically to Fig. 13, the same result is achieved by the form of the invention shown in Fig. 15, wherein the cam projection 388 is analogous in utility to thedepression 283 of cam 28! in Fig. 13. In Fig. 13, amanually operable contact 2% is provided to break the locking and bell ringer circuits, comparable to contact 248 in Fig. 12. Arm 300 (Fig. 15) is a manual reset lever and provides a means whereby bar 298 may be manually restored to its latched position.
A sprocket feed means such as is adaptable to printers herein described is shown in Fig. 16 and is fully described in U. S. Patent 1,884,760 issued to RA. Lake. In this illustration, the platen is indicated at Q and is provided with sprocket teeth 315 at each end arranged around the periphery thereof. These sprocket teeth mesh with marginal holes 336 in the record material composed of printed forms. Mounted on the platen shaft 94 and secured to platen 95 is the platen phasing cam 335, shown also in Fig. 15. The application of the structure shown in Fig. 16 to the structures previously disclosed is readily discernible.
