EEINSCEHIIDT, OF CHICAGO, ILLINOIS, ASSIG-NQR T TELETYPE COR?ORA- TION, 0F CEIGAGQ, ILLINOIS, A COBPOPt-ATION OF DELAWARE PRINTING: TELEGRAPH Reine of abandoned application serial its. 726,838,'fi1ed July 18, 1924. This application filed i iovember 30, 1928. Serial No. 322,946.

The present invention, disclosed in this application which is a duplicate of application 726,839, filed July 18, 1924 and Which was accidentally abandoned, relates to printing telegraph systems, and machines.

More particularly, the present invention relates to new and improved forms of synchronization, selective systems, and apparatus for type printing telegraphs.

Heretoiore certain types of printing telegraph systems have utilized. synchronously rotating elements at difierent stations, and

have maintained definite time relations by op erating the receivers at slightly greater speeds than the transmitter speeds, starting the receiver element into rotation at the beginning or each signal interval by a start-impulse, and arresting the receiver at the end of each rotation by establishing a stop condition. In these prior systems the transmitter element may rotate continuously under solely local control or may be started and stopped under solely local control between the start and stop intervals.

In the prior systems of the type described, the rotary receiver member is started into operation at the beginning of each signal 1nterval, and arrested at the end of each signal interval, and the angle of rotation for each complete cycle is 360 or less. Such systems are especially adapted for use with pr nting mechanisms of the type-bar form, as in the case withthe improvement above mentioned. A wide use for printers of the type-wheel These systems are also, in general, two wire' systems requiring two line wires-for their operation, with resultant loss of economy and decreased efficiency in the utilization of line wire. By reversing the operation of the usual start-stop rotary members of the permutation selector systems, and stopping the operation of a selector member at the beginning of each signal interval or cycle, and startingit at the form exists in the stock ticker and other fields. 1

end thereof, I have evolved an entirely new typeof selective system which permits the application of permutation codes to typewheel printers by simple, reliable, efficient and from one case to another requires a full cycle.

for each case movement. Because of the frequency of the shift operations in stock tickers, if the usual shift is utilized, the operation of the printer is slowed considerably. To'avoid this dificulty, a novel type of shift is provided by the addition of a special interval to the signal cycle, during which interval the selection of the figure or letter case is determined. By utilizing this new method of case selection, a high s eed of operation is attainable. A further'ieature of eliminating special case selecting signals is that reliable printers suitable for use in emergency signalling, such as in police and fire telegraph printing systems is provided. In such systerns, when special signal combinations are used to shift from letters to figures, it is found that operators'may forget to send the shift signal or the restoring signal when transmitting information that is urgently needed, with the result that serious relays occur at times when speed is most essential. By utilizing the novel case selecting methods hereinafter set forth, these diificulties are eliminated.

A furtherobject of the invention is the provision of new types of selectors in which the case selection is determined by an impulse interval in each signal, instead of by special signal combinations.

In operating systems of the character described,using type-bar or type-wheel printers, it is necessary. to establish substantially any form speed conditions at the various stations. Heretofore, motors with special speed governors have been provided, at all points. The governors add complications, require considerable maintenance, and are subject to failure. By experimentation, I have found that it is possible to eliminate at points where alternating current is available, motor governors thru utilization of over-size induction motors to drive the apparatus. If the driving motor is made sufficiently large so that only a small percentage of its rated capacity is utilized, the motors will operate with substantially no slip variation under the'varying printing loads, and the speed Will be maintained in substantial synchronism, the fluctuations in speed being well within the margin of operation of the apparatus.

Another object of the invention is therefore, the provision of simplified and more reliable motor driving arrangements.

In type-wheel systems utilizing extra im- 7 pulses to initiate and arrest the selective operation of the receiver, as in the well known start-stop systems, the type-wheel is arrested to effect printing or to effect the start-stop synchronism, and a blank space must be allowed on the type-wheel. Arresting the heavy type-wheel throws heavy strains on the apparatus which decreases the life and reliability of the printers.

Another object of the invention isto provide a system in which the type-wheel is not arrested at anytime during the operation of the printer and in which no blank spaces on the type-wheel are required.

Still other objects of the invention are the provision of new and improved high speed selectors, new and improved printing actions, and such other objects as will appear in the following disclosures of preferred embodiments of which Fig. 1 is a front elevation showing a typewheel printer.

Referring to Figures 1 and 2, a suitable base 1 is provided from which all the parts may be supported in a manner to form a compact self-contained unit. An oversize induction motor 2 is provided and in operation it drives continuously a helical gear 3, which in turn drives a helical gear 4, rigidly secured to a shaft 5. Shaft 5 is suitably supported ina bearing member 6, and in a bearing 7 sup ported from base 1. On the upper end of shaft 5, a drive pinion is mounted not shown) which drives a helical gear 8. ear 8 in turn secured to and drives continuously a'main shaft 9, which. ismounted in ball orantifriction bearings 10 and 11. Bearings 10 and 11 are similar in structure but preferably reversedin direction, as indicated inFig. 2. The bearings comprise hardened rings 12, (Fig. 3) rigidly secured to shaft 9 and bearing against balls 13 which in turn are supported and confined against hardened races 14; secured in housings 10 and 11. End covers 15 are provided to hold the bearings in assembled relation.

Rig-idly mounted on shaft 9 and rotatable therewith is a type-wheel 16 and a flange or disc 17 Upon boltsorsupports l8, fastenedto flange 17 are mounted sets of rollers 19 (Fig. 3) spaced apart by spacing member 20. Mounted on rollers 19 in a manner to have a slightrelative rotary motion with respect to the flange 17, is a cam ring 21, a shutter ring 22, a shift ring 23, and five selector rings 24, 25, 26, 27 and 28. Cam ring 21 and shutter ring 22 are fastened so that they will move together by means of rivet connections 29. Formed integrally with shutter ring 22 is a stop member 30. Member 30 extends across slots 31' (Figs. 3 and at) in rings 23 to 28 and limits the "relative rotary motion thereof with respect to the shutter ring and cam ring. Secured integrally 0r fastened to flange 17 is a stop member 32 (Fig. 4) which extends across slots 33 in rings 21 to 28 and limits the relative movements of these rings with respect to the flange? A plurality of springs 34 individual to shutter ring 22 and to each of rings 23 to 28 (Fig. 4) fastened to the respective rings at one end thereof, and to a member 35 projecting from flange 17 at the other end thereof tend to urge the respective rings clockwise in Fig. 4 against stops 30 and 32. Pivoted to a member 36 pro ecting from flange 17 are a plurality of selector fingers 37a to 37;, and ashutter trip finger 37 9 (Figs. 3, 4 and 5). Finger 37 g is individual to rin 22 and selector fingers 37a to 37 f are indivi ual to the rings 23 i028 respectively. The shutter and selectorfingers are normally held to the right inFign. 4 by means of springs 38 individual thereto, one end of each spring 38 being secured to its'individual finger and the other end thereof being secured to a member 39 projecting from flange 17. Shoulders 4G and 41 are cut into each of the rin s 22 to 28, and sprin s 34 normally hold shoulders 40 against t e ends of fingers 37a to 37 g in which position shutter ring 22 and shift ring 23 are in unactuated position, and selector rings 24 to 28 are held in unselected'or unactuated position.

Each of the fingers 37a to 37 f has formed thereon a cam projection 42, and latch shoulders 43 and 44. A plurality of latch members 45a to 45; individual to the fingers 37a to 37f respectively are pivotally mounted on a spindle 46 supported from flange 17. Secured to each of the latches 45a to 45 are the ends of springs 47, individual thereto, the other ends of which are fastened to member 48 secured to and projecting from fiange 17 in a manner to throw latches 45 to the right in Fig. 4. Shutter ring finger 37 g is rigidly secured to an actuating member 49 (Figs. 3 and 5) by means of a connecting member 50, and has formed thereon an actuating cam projection 42;

Coacting with fingers 37a to 37 f and latches 45a to 45; are a set of selecting cams 51 to 56 (Figs. 3 and 4), a start pin 57, and a shutter ring trip cam 58. Cams 51 to 56 are fastened in helical arrangement on a cam shaft 59. Cam shaft 59 has reduced sections 61 and 62. End 61 is rotatably and slidably supported in a bearing recess 63 formed in the end of shaft 9 (Fig. 3) and end 62 is slidably supported in a sleeve 64, (Figs. 3 and 4) with which shutter trip cam 58 is integrally formed. Sleeve 64 is supported through ball bearings 65 on a hardened steel bearing member 66 which in turn is secured in bearing support 67 (Figs. 2 and Fastened securely to sleeve 64 by means of a screw thread or in any other convenient manner to be rotatable therewith, is a friction brake member 68, one end of which abuts against balls 65 and prevents endwise motion of sleeve 64. Extending from the end of sleeve 64 which carries shutter cam 58 is drive sleeve 69 into slots 70 of which a drive pin 71 and cam pin 56 extend to form a drive connection between cam shaft 59 and sleeve 64. Slots 70 (Fig. 6) are preferably cut at a slight angle so that when shaft 59 is driving sleeve 64, there will he a slight tendency for the shaft 59 to move to the left in-Fig. 3, but this condition may be altered or reversed if desirable.

End 62 of shaft 59 extends through sleeve 64 and has secured thereto in any suitable manner a shifting grooved member 72 (Figs. 2 and 3). Elie ends of a forked member 73 extend into the circular groove in member 72 in a manner to permit rotation of shaft 59, and to shift shaft 59 endwise due to movement of member 73. Member 7 3 is rigidly secured to armature 74 of a selector magnet. The selector magnet preferably comprises a permanent magnet 7 5 supported from base l (Fig. 2) upon one pole of which armature 7 4 is pivotally mounted at 76. A, laminated U-shaped soft iron core 77 is mounted on the other pole thereof and upon legs 78 and 79 of which'windings 80 and 81 are applied.

In operation, when the windings 80 and 81 are deenergized, legs 78 and 79 will be in the same magnetic condition, and armature 74 will be held in position with one end thereof against either leg 78 or 7 9. WVhen, however, a marking condition is received, the magnetism of leg 79 is decreased due to the effect of winding 81, and the magnetism of leg 78 is increased due to the elfect of winding 80, and the armature and cam shaft actuated thereby will assume the position shown in Fig. 3. When the current is reversed and a spacing condition is received, the magnetism of leg 78 is'weakened and that of leg 79 is strengthened with the result that the cam shaft 59 is moved bodily to the left in Fig. 3.

The relative arrangement of selector fingers 37a to 37f, latches 45a to 45 and cams 51 to 56 is similar to that shown for the single magnet selector disclosed in copending application, Serial Number 649,562, filed July 5, 1923, and the same functions are performed thereby. It will therefore be clear that a neutral receiving magnet with a spring returned armature may be substituted for the polarized arrangement above described, as set forth in the said application to shift the cam shaft axially. As shown in Fig. 3, the relative widths of selector fingers 87a to 37f and member 49 are such that in the position of the cam shaft to the right in Fig. 3, as the cam pins 51 to 58 are engaged by the passing cam surfaces 42 and 42 of the fingers 37a to 37f, the fingers will be moved to the left in Fig. 4 to selected position, and latches 45a to 45;" willride over shoulders 43 of the fingers and lock the set fingers in actuated position. As will more fully hereinafter appear, the fingers, latches and rings are rotated continuously in operation, while the cam shaft is stopped at the beginning of the reception of each code combination and started at the end thereof. This is the reverse of the operation in the said copcnding case, where the cam shaft is started into operation at the beginning of the reception of each code combination and arrested at the end thereof. As in the said application, when the cam shaft is moved to the left in Fig. 3, by the reception of a spacing condition, cams 51 to 56 are shifted to thc'left in Fig. 3 in which position they will pass along side the respective fingers 37a to 37 f, and no setting will be made.

The latches 45b to 45f of the selector fingers 37b to 37 f controlling the selector rings 24 to'28are sufficiently wide to be actuated and restored'in either marking or spacing position of the cam shaft by cams 52 to 56. Latch 45a individual to the shift ring selector control finger 37a is however offset so that cam 51 while functioning to set selector 3741, will not restore latch 450:, the restoring of 4505 being efiected by start pin 57. Start pin 57 andcam 52 are aligned as shown in Fig. 3,

so that latches 45a and 456 are simultaneously restored. The relative position of cams 51 to 58 is such that cam 53 is restoring latch 4501 while cam 51 is setting finger 37a, cam 54 is restoring latch 45d while cam 52 is setting 3Tb, cam is restoring 450 while cam 53 is setting 37c, cam 56 is restoring 45f while cam 54 is setting 3T4], cam 55 then sets 370, and cam 56 follows in setting 37;. A selec tion is then completely set up on fingers 37a to 37 and when this is completed cam 58 actuates member 49 and trips the shutter ring for purposes which will more fully hereinafter appear.

It will be noted that cam 58 is fixed to sleeve (it and will not be shifted with the cam shaft 59. Accordingly, the shutter ring is invariably tripped after the position of 37; has been determined.

In addition to the function of restoring latch 45a, start pin 57 is normally arranged to engage a bevelled edge of a drive projection 82 (Figs. 3, 7 and 8) of an orienting member 83 pivotally mounted on extension 61 of shaft 59 and held against flange 17 by a clamping member 84, a spring 85, and a screw 86. lVith the parts in the position shown in Fig. 3, shaft 59 is driven by flange 17 through pin 57. The drive projection- 82 is preferably, but not necessarily, bevelled as shown to assist the selector magnet in moving the cam shaft to the left in Fig. 3 to initiate a selective operation. A continuous frictional drag tending to resist rotation of cam shaft 59 is applied by means of a brake band 87 (Figs. 2 and 3) which bears against friction brake member (38, and is fastened to suitable support 88 secured to base 1. The friction exerted by band 87 is such that when the cam shaft 59 is moved to the left in Fig. 3 and olf the bevelled surface of drive member 82, the cam shaft will come to rest while the remainder of the apparatus is rotated with shaft 9 and flange 17, and at the end of a revolution of member 82, if the cam shaft has been moved to the right in Fig. 3, member 82 will re-engage start pin 57 and will again drive shaft 59.

By adding to the orienting plate 83 a special start or drive member 89 so positioned and bevelled that when the cam shaft is to the left in Fig. 3, during the last selecting interval, pin 57 will engage this member and shaft 59 will be driven thereby until the last interval of a signal is received during which shaft 59 is invariably moved to the right in Fig. 3 when it will again be stopped until engaged by 82 and started at the end of a cycle. Member 82 ispositioned to engage pin 5'? in such position that pin 56 will have just passed .rojection 42 of 37;. It will be noted that if the last selecting impulse is a marking condition, pin 57 will engage member 82 directly and will start into rotation. By the adding of drive member 89, a wider speed difference between the transmitter and receiver may be used, thereby increasing the operating margins and efficiency of the selector. At the same time signalling intervals of equal length may be used on the line without materially shortening the time for the transfer of the selection from the selector members in the last or stop signal interval. In the usual form of start-stop selector, it has been common to lengthen the last interval of each signal combination to obtain sufficient time for the transfer of selections in the receivers.

This lengthening of the last interval is un- 'It will, however, be understood that the case control may be eliminated or controlled by special signal combinations in a well known manner. Besides being useful in machines of the stock ticker type, this new method of selecting the case is highly valuable in emergency signalling systems, such as fire and police systems, where serious delay may be caused at vital times, when an operator using the prior well-known forms of shift control by the transmission of special code combinations, forgets to return the printer to the proper case. This defect is completely eliminated by the present method of case selection.

As above pointed out, the shift ring and the first selector ring control fingers and latches are restored during the first interval of a signal, the finger and latch controlling the second selector ring are restored during the second interval, the third signal inter val and so on until the .fifth interval the fifth selector is restored and the precedin selection has been completely cleared off. is each of the fingers is actuated in accordance with a received marking impulse, and latched in actuated position, the ends thereof are removed from engagement with shoulders 40 of rings 23 to 28, and the selected ones of these rings will be conditioned for movement. The released ones of these rings will be held against movement by stop 30 until finger 379' is actuated, (Fig. 3). Simultaneously with or slightly after the setting of ring 28 is determined by cam 56, cam 58 actuates 37g through 49 and 50 and removes the end of 379 from engagement with shoulder 40 of shutter ring 22, and ring 22 together with cam ring 21 will shift under the influence of its spring 34; and springs 34 of the released selector of shutter ring 22 to form teeth 93 rings, until the edges of the notches 33 engage sto 32 carried by flange 17. The release of t e shutter ring and movement of the selected ones of the selector rings initiates a printing operation of the selected character.

' As previously explained, the latches a to 45 are reset progressively during the reception of each code combination. However, the tripped fingers 37 a to 37/ are only partially reset. The movement'of fingers 37a to 37], and relative positions of shoulders 43 and 44 is such that in actuated position with ends of latches 45a to 457 against shoulders 43, fingers37a to 37 f will be clear of and out of engagement with the shoulders 41 of the shifted rings, so that, as latches 45a to 45 are kicked ofi shoulders 43, there will be suflicient movement of the fingers before engaging shoulders 41to lock the latches 45a to 45f in restored position. The released or selected rings are restored to latched position as hereinafter described.

As hereinbefore set forth, shaft 9, together with flange 17 and the parts carried thereby are continuously rotated. -A plurality of V-shaped notches 90 which correspond in number with the number of combinationswhich may be set up on the selector rings, or-with the number of printing positions of the type wheel 16 are preferably cut at uniformly spaced intervals in the periphery of flange 17 in a manner to form teeth 91 (Figs. 1, 3 and 4). An equal number of similar notches 92 are cut into the peri 1l rery lgs. 1 and 4). The relative position of the flange 17 and ring 22 is such that in unactuated position, 'as shown in Fig. 54, the teeth 93 of the shutter ring are'out of alignment with the teeth 91 of the flange ring and form a continuous support for seeker bars 94 and 95.

When the shutter ring is released, however, it assumes a position in which notches 92 align with notches 90 andteeth' 93 align with teeth 91 so that the seekers 94 and 95 are :free to enter these notches as the flange and parts carriedthereby are rotated. The shutter ring 22 and the flange 17 are slightly greater in diameter than the rings 21 .and 23 to 28, so that when the shutter ring is in unact-uated position, the seeker bars will be raised clear of these rin Bar 94 is the figures control seeker and is merely wide enough to cover flange 17, cam "disc 21, shutter ring 22 and shift control ring 23. The bar 95 is the letters control seeker and extends across the flange 17 and'all of the rings 21 to 28. Cam

around sleeve 111 and .normally interference with the, movement of seekers 94 and 95 into the aligned notches of'the flange and shutter ring will be caused thereby. Shift ring 23 has notches 96' cut in the periphery thereof in a manner to form teeth 97 which in unactuated osition of ring 23 will prevent movement 0 seeker 94 into the aligned notches of. the flange andshutter ring, and in actuated position will permit movement of this seeker into the aligned notches. The selector rings 24 to 28 have cut into the periphery thereof a plurality of V- shaped notches 98 which form teeth 99, the notches 98 being arranged in accordance with the well known notched disc arrangement of the Baudot types of selectors, so that only one set of notches willbe aligned for each of in selector rings 23 to 28 and, until this alignment passes under seeker 95, one or more of the teeth 99 will arrest the inward movement of seeker 95.

Seeker 94 is carried on supporting extensions 101 (Figs. 1 and 4) pivotally supported on a spindle 102 which is carried by a bracket 103. A spring 104, urges the seeker 94 to-- wards the right in Fig. 1. Pivotally supported on spindle 102 is a sleeve 104, carrying a fi e control trip member 105. Sleeve 104 suitably positions member .105 between members 101. A helical spring 106 wound around sleeve 104 with one end abutting against the lower edge of 94, and the other end thereof fastened to 105 forms a yielding connection which normally forces the upper end of 105 and the under side of.94 into engagement (Fig. 4). seeker 95 is carried by supporting extensions 107 pivotally mounted on 'indle 108, which in turn is secured to brac et 109. Spring 110 secured to 107, and bracket 109, throws 95 to the left in Fig. 1 against the rings. Secured to a sleeve 111 is a letters control trip 112. Sleeve 111 is rotatable on. spindle 108 and suitably spaces trip '112 between members107. A helical spring 113 is wound holds the upper end of 112 and the lower surface of 95 yieldin ly in engagement.

A be lcrank member 114 rigidly secured to a rotatably mounted hammer control spindle 115 has one arm thereof-pivotall'y connectedto a link 116, and the other arm thereof is normall held against the lower end of member 105 y-spring 117 secured to a suit In a similar manner,

movement of member 119 as the end 119 thereof is engaged by the ends of the teeth of cam ring 21. The connection of link 1116 is such that bell crank 114 cannot move fully under the influence of spring 117 until bell crank 119 is fully released by movement of seeker 95, but bell crank 119 is freeto move fully even though seeker 94 does not release bell crank 114 for complete movement. When bell crank 119 is released, the end 119 thereof will drop fully into the notches of cam ring 21 and member 119 will be given a full rocking movement.

Spindles 115 and 120 are rotatably supported in bearings in members 10 and 11. Secured to spindle 115 is a platen stop memher 125 (Figs. 1 and 10) formed with an anvil end 126 and having fastened thereto a figure hammer stop 127. On spindle 120 and rotatable therewith is secured a hammer releasing or control member 128 (Figs. 1, 2 and-11) which has secured thereto a control and restoring pin 129. A letters printing hammer 130 and a figures printing hammer 131 (Fig. 11) are pivotally mounted on sleeves 132 and 133 carried by spindle 120, and the extensions 134 and 135 of the printing hammers are held against pin 129 by means of springs 136 and 137 secured at one end to the respective hammers and at the other end to pin 138. A tape feed roller rotatably mounted on sleeves 132 and 133 is made up of a central toothed ratchet wheel 139 and end flanges 140 and acts as a spacer between arms 130 and 131. A screw 141 and washer 142 hold the hammers and roller member in asis a jockey roller arm 14 carrying a jockey I roller 148, and an arm 149 carrying a tape tensioning roller 150. A helical spring 151 wound around 146 and fastened to arms 147 and 149 normally forces roller 148 between the teeth of ratchet wheel 139, and forces wheel 150 against flanges 140 to guide and tension tape .152. Platens 153 and 154 carried by hammers 130 and 131 are arranged to force tape 152 upward against the letters type 155 and the figures type 156 of type wheel 16. A suitable inking roller 156 is provided for the type. It will of course be understood that platens of composition of rubber-like material may be used to avoid battering of the type. Hammer 130 is provided with a stop extension 157 with surfaces 158 and 159, (Figs. 1, 12 and 13) arranged to co-act with anvil 126, and hammer 131 is provided with a stop extension 160 arranged to co-act with anvil 126 and member 127. Guide pins 161 and 162 guide tape 152.

As shown in Fig. 4, in order that the teeth of cam ring 21 will restore the arm of 119 over shoulder 123, it is necessary for 119 to extend sufiiciently upward when in latched position so that the ends of the cam ring teeth engage it, causing a slight rocking movement of 119 as the ring rotates. This slight movement and the continued rubbing of the ends of the cam ring teeth on 119 may be avoided by utilizing the arrangement shown in Fig, 14. In this form the projection 119 is formed integrally on a forked member 163 which is pivot-ally secured to member 119 by means of pin 164. Extensions 165 and 166 of member 163 co-act with spindle 120 upon which 119 is mounted to limit the pivotal movement of member 163. A light spring 167 secured to extensions of 119 and 165 respectively, normally urges 165 into engagement with spindle 120. With bell crank 119 latched up as shown, the end of 119 is held clear of the cam ring teeth. W'hen seeker 95 trips latch 112, projection 119 drops into engagement with the cam ring periphery, and as the cam ring rotates and member 119' moves outward, a force is exerted which tilts member 163 upward about its pivot 164 until extension 166 engages spindle 120, and then further movement of the ring forces the end of bell crank 119 upward until caught by shoulders 123. As soon as the high point of the tooth passes the end of 119, spring 167 will restore fork 163 to the position shown in Fig. 14 where it will again clear the cam ring 21.

General operation.

As hereinbefore in detail described, motor 2 continuousl drives shaft 9 upon which type wheel 16 an the flange 17 are carried at a speed above the speed of the transmitter member. The line condition is normally such that cam shaft 59 is held to the right in Fig. 3 by the line magnet, and in this position, the cam shaft is driven with the flange 17 and parts carried thereby through member 82 and pin 57. The first condition of each code or signal combination is such as to cause the line magnet to shift the cam shaft 59 to the left in Fig. 3 and as soon as this occurs, the pin 57 drops ofi member 82 and is stopped due to the frictional dra of member 87 on member 68.

The timing of the speed of rotation of shaft 9 is such that surfaces 42 of selector fingers 37a to 37 f are carried past their respective cams 51 to 56 in properly timed relation with respect to the incoming impulses so that the selectors will be set or remain unaffected, in accordance with the reception of a marking or spacing impulse in the proper interval. After the selectors are set in accordance with the received character, cam 58 trips the shut ter ring 22 and permits the released shift and selector rings 23 to 28 to assume their actuated or selected positions. If the impulse controlling selector 37 f is a spacing condition, pin 57 will be engaged by member 89 and shaft 59 will be driven until the last impulse of the signal is received when the cam shaft will again be moved to the right in Fig. 3, and shaft 59 will again come to rest until engaged by member 82. The cams on shaft 59 are so spaced that a relative angular rotation of'48% between the cams and the selector fingers is allotted to each of the first seven signal intervals, and an angle of 18% is allotted to the last interval, making a total of 360. The time interval of all seven impulses is uniform, however, so that a definite.

time of engagement between member 82 and pin 57 will occur at the end of each signal.

Tripping of the shutter ring by cam 58 permits the selector rings to assume actuated position in accordance with the received signal. For each signal a predetermined row of notches in flange 17 and rings 22 and 24 to 28 will be aligned. If a letter is to be printed, shift ring 23 willbe aligned to permit inward movement of seeker 94. If a figure or a.

special mark is to be printed, ring 23 will be tripped and all of the slots in flange 17 and rings 22 and 23 will be aligned. Accordingly, the rings rotate with seekers 94 and 95 en aging their respective controlling rings. f a letter is to be printed, member 105 will prevent movement of arm 114. As the aligned slots in flange 17, and in rings22 and 24 to 28 pass under seeker 95, this seeker will move.

inwardand move member 112 to trip arm 119. Tripping of arm 119 permits movement of pro ection 119 thereof into a notch in. cam ring 21.11nder the influence of. spring 124. This movement of 119 moves pin 129 downward through spindle 120, and springs 136 and 137 will cause movement of hammers 130 and 131. As arm 114 was not tripped, members 126 and 127 will be in the position shown.

in Fig. 12, and extension 160 of hammer 131 will engage member 127, preventing upward movement of the platen 154. Extension 157 of hammer 130 Wlll, however, move upward until surface 159 thereof engages anvil 126, in which position platen 153 willpress tape 152 upward to effect printing of the selected letter. If ring 23 is tripped to select a figure, seeker94 will be oscillated by movement into and out of the aligned slots, but member 114 will not move, due to connecting link 116, until seeker 95 moves into the aligned-slots as above set forth, to trip 119. In this case, member 114 will move to rock spindle 115 counterclockwise and position members 126 and 127, as shown in Fig. 13. In this position, surface 158 of extension 157 will engage anvil 126 and. a printing movement of platen 153 will be prevented, while hammer 131 moves upward under the influence of spring.

137 and causes a printing impact of platen 154 to print the selected figure.

Owing. to the fact that the unselected ones of rings 24 to 28 are positioned with the edges of slots 33 thereof engaged by member 32 as shown in Fig. 4, these unselected rings will immediately force seeker 95 outward after it has moved into the aligned notch. The drag exerted by member 119 against the side of the notch on cam ring 21 and the drag on the released selector rings will momentarily retard or arrest the rotation of these members until member 32 on flange. 17 engages the forward edges of slots 33 of the selected rin s, when the cam ring, the shutter ring, and t e released selector rings will again be positively driven by the flange 17. As soon as 32 engages the edge of the selector, shutter,'and cam ring slots 33, fingers 37a to 37 y will lock them in unactuated position and member119 will be cammed outward, latching members 114 and 119, as shown in Fig. 4 or Fig. 14, as the case may be. This movement of arm 119 throws pin 129 upward to restore the hammer 130 or 131 as the case may be, and to advance the tape through operation of pawl 143 or 144. The printing parts will then be restored to the position shown in Fig. 1.

It will be observed that in order to effect printing of each character, a minimum average angular rotation of 360 plus the angular drag of the rings, or more must be covered by the flange 17 and shaft 9. In the present continuous. The minimum possible angular rotation between printing of characters for continuous reception is the angle of drag plus one half the angle between the teeth on the cam ring. The printing of characters is irregular in timing, but will average out so that each character received is printed in a minimum possible time, and without arresting I the movements of the type-wheel to print, as has been heretofore common in type-wheel systems in which distributing members are maintained in properly timed relation by utilizing special impulses to initiate and arrest the selective operationsat the beginning only, what is desired to be secured by Letters Patent and claimed as new is:
