SELECTING MECHANISM ron TYPE-PRINTING TELEGRAPHY AND ornnitrunrosns.

Application filed February 23; 1927, Serial No. 170,334,:11111 in Great Britain February 26, 1926.

This invention relates to selecting mechanism more particularly for type-printing telegraph systems, although this invention like that constituting the subject matter of the U. S. specification Serial No. 65,308, of Thomas James Berryman on which it is a modification or improvement is not limited to printing, as it'may be used for efiecting other operations under electric telegraph control.

The subject matter of the prior patent is a means for directly translating Morse code signals, the means consisting in the particular examples described therein, of two signal 0p erated devices co-operating with a translating cylinder provided with grooves or proj ections so as to move the said cylinder axially and rqtatively. into dilterent positions for different signals; the said translating cylinder either operating a type drum in the case of printing or operating to close electrical circuits for giving any other required action.

Now this apparatus is equal letter code signals provided that the impulses of the different letters are received and treated insequential order and other adustments are effected as will be understood from the following description.

According to this invention the two-signal operated devices are arranged to respond I in the sequential order of and to act difier ently for different impulses of the equal letter code and thereby causing the translating device to move differently for difi'erent letters of said code.

Other features of this invention will be apparent from the following description and will be more particularly pointed out in the claims. p

Fig. 12 is a nism.

As the apparatus is not only applicable to printing it is proposed, in order to clarify the description, to describe firstly the construction and operation of the apparatus for printing and then to indicate the construction and operation of the apparatus for other purposes. .76

In the first case consider the form of the apparatus shown in Figs. 1 and 2 of the accompanying drawings. In this case the means for translating the signals comprise an lmpelling device in the form of an escapement mechanism giving at each operation an increment of axial movement to the translating cylinder and control means cooperating with means on the translating device which will act when necessary to modifythis movementof the translating device and in this way cause the device to act diflerently both for a-diiference in order as well as in the kind of impulses received. It will therefore be seen that the apparatus comp-risesfour main parts (1) the signal operated devices, (2) the translating device, (3) the printing detail ot the printing mechamechanism, and (4) the restoring-apparatus- Signal operated devices.

A polarized relay 1 ('a relay in which the reed 2 is normally held in a central position .and is moved to either side according to the character of the impulse) is provided, the magnets of which are energized by the signal current in the receiver circuit 3 and the relay acting when energized by impulses of either kind to close the local circuit 4 conneeted with the magnet 5 operating the pins of which only one, 6, is shown) of the escapement mechanism 7 for giving axial movement to the translating cylinder.

The local circuit 4 extends from the reed 2 around the magnet 5 around zfnother magnet 12 (hereinafter described) to one contact 13 of therelay 1. The other contact 14 of the relay is connected by the conductor 15 to a contact 16 of a switch 17 in turn connected through a resistance 18 with the circuit 4. The circuit 4 contains a source of E. M. F. 19. The magnet 12 operates by means of the armature 20 the pins 32 and 33. An insulated pin 24 is provided for operating the switch 17. This pin 24 is connected with the translating cylinder or a cam on a suitable shaft so that on receipt of the first positive impulse it is moved to close the switch.

Negative impulses act to move the reed 2 on to contact 14 which when the switch 17 is closed, closes the circuit through the conductor 15, switch 17, resistance 18, left hand part of circuit 4, magnet 5 and back through the reed to contact 14. Positive impulses in the receiver circuit act to move the reed 2 on to contact 13 so as to close the whole circuit 4 through both magnets 12 and 5. The switch 17 is provided to prevent the magnet 5 being energized by negative impulses at the commencement of each letter by preventing the local circuit from being closed until the reed has first been actuated by a positive impulse.

This is effected by normally retaining the switch open as shown by the member 24, the

switch being reset at the end of each signal.

The magnet 12 is arranged to act faster than the magnet 5. In order to balance the local circuit and avoid excessive use of local battery the resistance 18, equal to the resistance of the magnet 12 is provided, this resistance coming into use when the magnet 5 only is energized.

The magnet 5 attracts the armature 26 mounted upon the rocker 27 and moves this rocker against the action of the spring 28. This movement, through the medium of the stop 29 on the rocker 27 and the stop 31 on the arm 35, releases the pivoted arm 36 and allows the pin 37 which contacts therewith to rise under the action of the spring 38 so that the pin 37 is moved out of engagement with the scape wheel 39 and allows this to rotate. At the same time the stop 40 on .the member 27 engages with the stop 42 and moves the arm 43 downwardly, this arm depressing the pin 4- against the action of the spring 45 so that it moves into a position to engage with teeth on the scape wheel 46. These two scape wheels form a compound scape wheel which gives a similar effeet to that of the well known fast and loose action of typewriter escapement mechanism' movement of the scape wheel is conveyed through the crank 49, the connecting rod and universal joint 51 to the main shaft 52 and is arranged to give the shaft an increment of axial movement for each step of the escapement wheel, rotation of the universal joint being prevented by the pin 53 and stop 54. The scape wheel 39 is provided with a stop 55 which on the resetting of the escapement as hereinafter explained rocks the arm 56 carrying the arm 35, which is pivoted at 59 and this ensures that the pin 44 is depressed.

Translating device.

a cylinder as shown in Fig. 7 the switch 17 will be dispensed with so that every impulse whether positive or negative acts on the magnet controlling the escapement for imparting axial movement to the translating cylinder.

Another magnet is provided operated only on receipt of a positive impulse and acting on the pins which engage with the guides on the translating cylinder, which pins are marked 32 and 33 in Fig. 7 so that on receipt of a positive impulse, the pin 32 is withdrawn from the channel 60 with which it normally engages and the pin 33 will be inserted in the channel 61.

For each letter we shall have five impulses and as each impulse imparts a step of axial movement to the cylinder we shall have five steps of axial movement of the drum for each signal. These steps are indicated by the transverse lines marked 0, I, II, III, IV and V; 0 being the zero or starting point.

The operation will be readily understood from a description of the action on receipt of the signal representing B which consists of two negative impulses, followed by two positive impulses and a final negative impulse.

The lirst impulse being a negative impulse merely operates the magnet controlling the escapement and imparts one step of axial movement to the cylinder. As the magnet control] ing the pins 32 and 33 is not energized the pin 32 will remain in engagement with the groove U0 and by reason of the axial movement imparted to the cylinder the latter will be moved into a position in which the point (52 is beneath the pin As the channel (30 is inclined between the lines 0 and I, and as the pins 32 and 33 are stationary, the cylinder will be rotated. The next succeeding impulse being a negative impulse will act in a similar way and will bring the point (53 into a position beneath the pin 32 and impart further rotary movement to the cylinder. As the succeeding impulse is a positive impulse the cylinder will notonly be given ILStQP of axial movement but the pin 32 will'be withdrawn from the groove 60 and the pin 33 willbe inserted in the groove 64. Now as the axial movement is imparted to the cylinder the point '65 will be brought into a position opposite the pin 33 and on the deenergization of the magnet controlling the pins 32 and 33 the pin 32 will be inserted-in the channel 66 and the pin 33 withdrawn from the channel .64 leaving the point 67 beneath the pins 32. As however the next succeeding impulse is a positive impulse the magnet controlling thepins 32 and 33 will :again be operated withdrawing the pin 32 from the channel 66 and inserting the pin 33 in the channel 64 and the cylinder will be given a. step of axial movement by this impulse, bringing the point 68 beneath the pin 33 and as before on deenergization of the magnet the pin 33 will be withdrawn and the pin 32 inserted in the channel 69 at the point marked 7 0. The final impulse being a nega' tive impulse merely imparts a step of axial movement to the drum bringing the point 71 opposite to thepin 32. This is the position the cylinder corresponding to the letter B as indicated. In each case as the cylinder moves 'an' equal amount for each letter the printing action may bestarted'by the translatin cylinder and the ap aratusmay be re-.

stored to its initial condition (as hereinafter described) V "In order to simplify the apparatus and to increase its speed it is referred to employ the modified form of cylinder shown in Fig. 8 which is the form intended tobe used with the apparatus shown in Fig; 1 of theaccompanying drawings. The construction and action of this form of cylinder will be clear from the following examples Taking the letter B as before which is represented by two minus impulses followed'by two positive impulses and -a final negative impulse the two first impulses will have no effect upon the translating cylinder 79. The first positive impulse howeve'rwill energize the magnet 12 causing it to withdrawthe pin 32 from the channel and insert the pin 33 in the channel 81 and as the magnet 5 controlling the escapement for giving 'axial movement will alsobe energized to act immediately after the magnet 12 the cylinder willbe given one step of axial movement. bringing the chain dotted line I into a position beneath the pin 33 and, on the restoration of the means operating the pins 32 and 33 after the passage of this impulse the pin 33 will be withdrawn from the channel 81 and the pin 32 will be inserted in the channel 80. The next succeeding impulse being a positive impulse, the pins and escapement mechanism will be actuated as beforemoving the point 82 on the chain dotted line 11 eventually into a position beneath the pin 32. The final impulse being a negative impulse merely energizes the magnet 5 so as to impart a step of axial movement to the cylinder and the pin 32 being in the channel 83 which is inclined between the lines II and III will rotate the cylinder and brin the point B thereon into a position beneat the pin 32.

If now this cylinder is coupled with the.

printing drum 84 shown in Fig. 9 in the manner shown in Figs. 1 and 213118 letter B will be moved into printing position.

' Pmm The printing is effected by a tgpe drum 84 fixed upon the shaft 52 so as to moved by the translating cylinder to bring the letters into a' position for printing. The actual printingoperation is effected by a printing ammer which moves the paper against the type at the end of each translating movement.

It is essential that thehammer should have v a iano-like action in order to clear the drum a ter it has been operated. All this is well known in the art and .need not therefore be further described.

The type drum and (or) the t pe may be removable for replacement or alteration or for changing the position of the character in accordance with change of code.

Restoring apparatus. i

channels in the cylinder and which shaft also Q.

actuates the arm 94, to reset the escapement mechanism in the well known manner. Thus the escapement mechanism through the crank 49 and connecting rod 50 moves the main shaft 52 and therewith the cylinder axially into its initial position. In cases where the cylinder has been rotated, it is rotatively moved into. its initial position by the means, a suitable form of which is shown in the prior specification referred to.

It may be mentioned here that as a modification of the above described signal operated means two-polarized magnets may be used,

one -operating each of the control pins 32 and 33' which'engage with the grooves in the cylinder and it may be arranged that both of these magnetscan, when excited, send a currentthrough the magnet controlling the escapement mechanism for giving axial movement when the said 'polarized magnets are energized. "In this case mechanical means for preventing the closing of the circuit of the magnet controlling the escapement or to break this circuit will also be provided so that the escapement will not be actuated by negative impulses at the beginning of a letter as aforesaid.

Having now considered the primary form of apparatus we will now consider applications of alternative form of the apparatus shown in Figs. 3 and 4 of the drawing for the equal letter code system. Let us consider first of all the form of cylinder shown in Fig. 10. This cylinder is operated positively by an eseapement mechanism adapted to give axial movement in the direction of the arrow 100 and the cylinder itself is arranged to act as an escapement to give rotary movement in the direction shown by the arrow 101 (in a manner which will be hereinafter described with reference to Figs. 3 and 4) In this case mechanism for giving axial movement may be so arranged that 1t positively moves one step axially on the receipt of each negative impulse while the cylinder is allowed to rotate to an extent determined by the projections 102 thereon on the receipt of each positive impulse. 1

In this case a polarized relay may be provided so arranged that it is energized by the incoming impulses and serves to close a local circuit either to the magnet controlling the axial escapement or the magnet controlling the pins 32 and 33, to give axial movement or allow rotary movement of the cylinder according to whether the impulse is a minus one or a positive one as previously described. The operation in this case will be quite clear from the description of the operation on receipt of a signal representing the letter B, two minus impulses and two positive impulses and a minus impulse in succession. The two minus impulses will merely act to cause the escapement to move the cylinder 103 in the direction of the arrow 100 bringing the point marked 105 into a position beneath the end of the pin 32. The next impulse being a positive impulse will act to withdraw the pin 32 and insert the pin 33 which will allow the cylinder to rotate until the point 106 is in a position beneath the end of the pin 33. On release of the magnet operating the pins 32 and the pin 33 will be withdrawn and the pin 32 will be moved down on to the point marked 100. The next succeeding impulse being again a positive one will withdraw the pin 32 and move the pin 33 on to the point marked 108 which will again allow the cylinder to rotate until the point 109 comes opposite the end of the pin 33 when again the restoration of the magnet operating the pins 32 and 33 will substitute the pin 32 for the pin 33. The final impulse being a negative one will merely move the cylinder axially to bring the space B into a position beneath the pin 32.

In the preferred form of this alternative form of apparatus it is modified in a similar The mechanical part of the apparatus shown inFigs. 3 and 4 in its essential features diti'ers only from that described with reference to Figs. 1 and 2 in the construction and operation of the translating device. In this case the escapementmechanism 110 is similar in all respects to that shown in Figs. 1 and 2 and it is operated by a magnet 125 to move the shaft 52 and with it the cylinder 112 in a direction opposite to that in Fig. 1 as indicated by the arrow. Also the cylinder acts as an escapement device being driven in the example illustrated by the gear wheel 113 on the shaft meshing with the elongated pinion wheel 114 so arranged as to allow the gear wheel 113 to move axially without interfering with the driving connection. The pinion is driven by the gear wheel 116 from a spring or other similar driving mechanism.

Thecylinder in this construction is merely provided with a series of longitudinal ribs 118 serving virtually as guides on its periphcry, these ribs being of different len hs as clearly shown in the developed plan, *ig. 11.

The polarized relay 120 is connected in the receiver circuit and serves to close either a local circuit consisting of conductors 121, 122, 123 and 124 containing the magnet 125 operating the escapement 110 which imparts axial movement to the shaft 52 or a local circuit consisting of conductors 127, 128 and 1% containing the magnet 129 which actuates the pins 32 and 33 according to whether the impulse is a minus one or a positive one respectively. The operation will be quite clear from what has been said with reference to Fig. 10 it only being necessary to add that a switch 130 similar in construction and operation to the switch 17, in Fig. 1 being connect ed in the circuit containing the magnet 125 which imparts axial movement to the translating cylinder so as to prevent the magnet from being energized by the minus impulses at the commencement of a letter, the switch being released on receipt of the first positive impulse and thereafter the magnets and other parts will function as described with reference to Fig. 10.

In a modification of the alternative arrangement described with reference to Figs. 3 and 4, shown in Fig. 5, the polarized relay is dispensed with and the magnets 132 and 133 are polarized and are connected in series in the main line circuit 134, the magnet 132 being energized by positive impulses and the magnet 133 by negative impulses. The operation is the same as that of Figs. 3 and 4 parallel in 142 having the switch 144 acts to interrupt the circuit ters to figures quired, this maybe efiected in any convenient except that instead of the switch breaking the circuit through the m 136 initially short .circults this through the circuit 137, 135 and earth 138, the switch being opened by the operation of the mechanism on receipt of first positive im ulses.

In a further modification of the a ternative arrangement shown in Fi ing with the polarized re a the two polarized magnets 140 and 141 are connected in the main line or receiver circuit an earth return 143. In this case through the magnet 140 until the magnet 141 has been energized.

It will be understood in. all cases where the five unit .code is used and printing is to be efiected a change-over arrangement from letprovided as the thirty one signals obtained arenot sufficient for the letters, numerals, punctuationmarks and other characters re- 152 working in suitable guides. The member A 152 is provided with projections 153-154 which serve to engage with andactuate a rocker 155 on which is mounted the platen 156 and tape guide 157, both the platen and tape guide being mounted 158 and 159 respectively. The retaining device 160 is provided to hold the rocker in either of its two positions determined by the 168 of the printing-m also used for actuating t 7 serving,

stops 167 and 168. The striker 161 normally for knocking the platen and tape against the st 162, but this is e rocker when letter blank or figure blank signals are received. It

will be seen that on operation of the striker 161 b the armature 168 the member 152 will be li by the pin 163 and this will cause one of the projections 153-154 to engage with and move the rocker-155 according to the position of the lever 151 and thereby moves the-platen and tape guide. The step 169 limits. movement of the member 152 and this eng'agingwith the in 163 prevents the strikermovin suflicient y to knock the platen when lette b ank-or figure'blank signals are received. a When the t pe drum has I both shiftpositions t e lever 151 is held again'st'the stop 164 by the weak spring 165 and the member 152 is then clear of the pin 163. A stop 166 is provided to'prevent the st 133, the switch- 6, again dispens-- or vice versa will have to be tape to bring it opposite the or) axial movement onleaf springs drum is actuated by the armature member 152 from falling beyond its normal 'tion. I Where, instead of signals composed of impulses which are entirely separate, signals composed of impulses in which the consecutive impulses of the same kind run into one another (as, for instance, in the Murray automatic system) a vibrator or rotary or equivalent distributor or contact make and break device may be used to break the long signals into separate impulses or, as an alternative mechanism for producing timed sliding or rotary movement could be brought into action, to give the requisite movement of thetranslatingt linder. In or er to effect operation other than mer printing, the apparatus can be used for other purposes. The translating device may be used, for instance, to select a particular electrical contact and bring it into a position beneath a fixed contact so as to close a local circuit in a similar manner to the ap aratus for this gle rpose described in my U. tion rial No. 65,308.
