-- i invention relates to transmitting appa- ,stored up code combination beforeit has been fratus for use in automatic telegraph signal- -.l1ngsystemsand particularly to the code storage mechanism employed therewith.

5 In order to obtain a uniform rate of signal transmission, it -is the practise to provide 4 some form ofcode storing means interposed -;b 'e tween the code bars or key levers on the Y keyboard and the automatic sender which im- .10 presses the stored code on the signalling cir- "cult; The code perforated on a tape is used in one of the'well known t es of storing devices. In this type the tape is first perforated under control of a keyboard mechanism in Iii-accordance with the codecombinations to be passed through- :latertransmitted and is then a tape controlled transmitter.

The" tape transmitter has 'been found to I have some disadvantages which'have prompt- -ed the development of what is known inthe art. a s the mechanical storage transmitter comprising groups of mechanical members operated in various combinations by key lewere and" later 5 controlling a transmitter beifore'=-being restored in preparation for a re- "operation by' akey lever. 'Whil'e man of the disadvantages of the tape'transmltter have'b'een eliminated by-themechanical storix-"age transmitter, many of those heretofore proposed have been found to-be slow in operation. due to the. inertia oftlie large moving ..,parts.

Accordingly it is an object of'my invention to rovidea mechanical storage'transmitter WhlCll haslight'inoving partsand can-trans mi-t signals at a high speed. I

Afurther diificulty which has been experienced-with storage transmitters resides in the lack of means for reventing the trans- 40 mission'of a code'com ination of impulses which has once been set up :with mechanical storage mechanism. As will be clear. to those skilled in the art, the operatoroften wishes ,to wipeout and prevent the transmission .of a code after it has been stored. This may for example, be due to ','an incorrectcode combination, accidentally stored. There has ac'-: cordingly existed along felt want for a simple eflicacious and cheap arrangement which would enable the operator tot. wipe out? any with parts omitted. Figure 3 is a-plan '."mechanism. 4.

ccordingly'a fu her-o ject of m invention-is to provide means for arbitrari y oblitcrating or wiping out any record which has been setup on the storage transmitter at any time prior to'the transmission thereof.

from the detailed description of each in the order set forth above In the drawings,-F1gure 1 shows a vertical cross section of a preferred embodlmentof my invention.

Associated with the first of the above units is the storage wipe out device which hk'e' the pin operating device is movable withrespect Figure 2 hows a. plan view of Figure Figure 4 is a side view of the stored pins and wipe out.

Fi ure 5 is a view of the mechanism for rotating the transmitter mechanism.

Figure 6 is a view partly in section of the mechanism for rotating the storage device, and

Figure 7 is a diagrammatic view of the operating circuits employed in carrying out my invention.

As shown in Figure 1, the support for the ap aratus comprises a frame 1, mounted upon a ase (not shown) and fixedly secured by means of the brackets 3 to a fixed tube 4. Supported by and, rotatably mounted with respect to the fixed tube 4 is an outer tube 5. Secured to the outer tube 5 is a collar 6 which supports a shelf 7. Mounted on shelf 7 are a group of magnets 8, which are connected incircuits selectively energized under control of a keyboard mechanism to be described in detail 1n connection with Figure 7.

Each of the magnets 8 is provided with an armature 9 havin an extensionarm 10 secured thereto an pivoted at 12 to the upright member 13 carried by the shelf 7.

Secured at one end to a pin 14 extending horizontally from the upright 13 is a spring 15, the other end of which is secured to the armatureextension or lever arm 10. Spring 15 norihally holds the armature in a non-op- .erating position away from the pole of the magnet 8 when the latter is deenergized. The pin operating end 16 of the lever arm 10 is positioned beneath storage pin 17 there being five pins in a group, each associated with one of the levers 10 as shown in Figure 3. When a magnet is energized, its armature 9 is drawn towards the pole piece of the magnet, a ainst the tension of spring 15 and in turn roc s the armature lever arm 10 in a counter clockwise direction about its pivot 12. The end 16 moves the storage pin 17 with which it is at the time associated from its lower position to its upper or operative position as shown in Figure 1.

Each of the storage pins 17 is provided I with a shoulder 18 WhlCh limits its movements between upper and lower annular members 19 and 20 properly secured to thering 21 on frame 1 and provided with o enings 22 through which pins 17 roject. ins 17 are arranged in cups of ve in a circle on the annular mem rs 19 and. 20. It will be understood, however, that the number in each group may be varied, depending u on the code to be sent, five being used in t e present illustration for a baudot code system.

An annular coil spring 23, Figure 4, carried between the annular members 19 and 20 maintains the storage .pins 17 in either operative or non-operative position. When a storage pin 17 is forced upwardly, its shoulder 18 moves upwardl against and pastthe outer edge of. the 1 spring 23 contracting the spring. 'When the shoulder 18 has passed by, the spring 23 expands and enga es the shoulder 18 of the storage pin 17 loc 'ng it in its elevated position. lln this manner the pins are locked in either operative or nonoperative positions.

. As shown in Figure 3, five ma ets 8 are provided each controlling an individual ex-. tension 10 for operation of an associated storage' pin 17. Combinations of these magnets are energized by each key operation and accordingly selectively control five of the pins 17 simultaneously. It will be clear that following the operation of each group of storage pins 17, it is necessary to associate the lever arms 10 with a'succeeding group of'pins. Heretofore this has been accomplished by rotating the members equivalent to the annular members 19 and 20 carrying the pins so as to bring a new group of pins into operative relation with the lever arms 10..-

As will be clear, the members 19 and 20 and erable inertia so that they operate slowly. I provide an arrangement in which, instead of moving the annular members and the associated pins, the tube 5 and with its shelf 7 carrying the magnets 8 and lever arms 10 is rotated with respect to the pins 17 and the latter are held stationary so that following each operation of a group of pinsa new set thereof are brought into operative relation with the lever arm 10. i

The necessary ppwer for tation of the tu e 5 is o tained from the spring 26, Figure 6, operating through the mova le ratchet 27 provided'with teeth 28, Figures 1 and 6. Ratchet 27 is secured to and rotatable with the outer tube 5 between the guide plates 2-9 and 30, Figure 1, on the main frame. A pawl 32 pivoted at 33 on the bell crank 34 is normally urged into engagement with one of the teeth at the tooth engaging end 34' by the spring 35, one end of which Y is secured to the pawl 32 and the other to the mounted on the main frame at 36 as shown in Figures 1 and 6 and is pivotally secured at 37 to the connecting link 38. Connecting link 38 is pivotally secured at its other end 39 to the plunger 40 of the solenoid 41 of any well nown type core 43.

Power sprin 26 is secured at one end to a pin 44 carriedaiy the arm 38 and at its opposite end to e e 45 of an adjustable screw 46 mounted on the main frame and normally holds the arm '38 and plungers 40 in the poand comprising a coil 42 and I roviding this rosition shown. When however the solenoid 41 is energized as will be described hereinafter, the plunger 40 is drawn inwardly between the and the toot engaging end 34 of the pawl 32 slides over one tooth into engagement with.

'30 are rotated into operative relation with a vthe next succeeding tooth on the ratchet 27,

preparing the latter for rotation through a distanceequal to the pitch of the teeth 28.

Upon deenergization of the magnet 41 the tensioned spring 26 pulls the plunger 40 and rod 38 outwardly rocking the bell'crank 34 in a counter clockwise direction about its pivot 36 and the tooth engaging end 34 rotates the movable ratchet 27, the pitch distance of one tooth in a clockwise direction.

' The outer tube is rotated with the movable ratchet 27 to in turn rotate the shelf 7 carrying the magnets 8 and extension, arms 10. The angular rotation is such that the five arms 10 which were formerly positioned beneath and in operative relation with the I preceding group of five storage pins are moved to'operative relation with the .next group of five storage pins. The magnets 8 are now again selectively energized in accordance with a key operation and the pins 17 are correspondingly operated. In this manner, in response to each key operation, as will be described in connection. with the electrical circuits shown in Figure 7, the magnets 8 operating though lever arms 10 position a group of storage pins 17 in accordance with a predetermined code to be transmitted individual to the key operation. Following the operation 'of a group of pins, the magnets succeeding group of pins.

In order to prevent counterclockwise rotation of the movable ratchet 27 while the tooth engaging end 34 slides over one tooth of'the ratchet, apawl member 51 is provided for engaging a tooth of the ratchet. Member 51 is pivotally mounted at 52 urged into en- "gagement with a tooth of the ratchet wheel 27 by a spring 53 secured at one end 54 to the pawl 51 and at the other end 55 to the frame (not shown). When the pawl 32 is being moved from one to the succeeding tooth, theholding pawl 51 in engagement with a tooth of the ratchet prevents counterclockwise rotation thereof. In addition the pawl 51 operates under control of the magnet 56 through its armature 57 rigidly secured to pawl 51 to permit rotation of the ratchet wheel in a counterclockwise direction in the manner and for the purpose to be described in detail-hereinafter. Secured to tube 5 near its upper end is one end of a spring 58,Figure 1, the other end of which is secured to the post 59. Post 59' in turn rotates a shelf 62 which controls the second unit or transmitting mechanisms re- -ferred to above, carriedby the post. 59 is a tooth 63 which isnormally in engagement with a tooth on a fixed ratchet wheel 64.

- Ratchet wheel 64 is secured throu h collar '65 to the fixed tube 4 bymeans o screw 66.

Tooth 63 normallyin engagement with the .fixed ratchet 64 prevents the spring 58 from rotating shelf. 62, V a

The shelf 62 is secured to and rotatable with'the inner tube 71 by collar 72. Tube 71 is loosely mounted in the tube 4 and is rotatable therein for rotating with the shelf 62 when the latter is released-for rotation by spring 58 upon the disengagement of tooth 63 with the fixed ratchet 64 as will be de-"/ scribed hereinafter- Fixedly secured to the,

These contacts are operated by individual feeler cranks 86 pivotally mounted at 87 on a slidable plate 88 through the ends 89 in engagement with the spring contact 84 in' accordance withthe setting of the pins 17 engaging the end 89 of the bell crank in a manner to be described as follows. The slidable plate 88 is carried by the shelf 62 v and slides between the guide plates 89', Figure 5, mounted on the shelf 62. In order to provide slidable movement to plate 88, a magnet 92, ,Figure. 1, is rigidly mounted on the shelf 62 and is periodically energized in a manner to .be described hereinafter for operating its armature 93.' Armature 93 is secured to the slidable plate 88 by the screws 94 and is normally held in the position shown in Figurel by s'prin 96, secured at one end to a pair of the guide plates 89' and at the other end to a cross bar 97. Cross bar 97 is secured by means of rivets to the slidable plate 88 so that the springs 96 normally hold the slidable plate. 88 in the position shown in Figure 5 ,in which the tooth 63 engages one of the teeth of the fixed'ratchet 64 preventing rotation of the shelf 62.

As will be described more fully hereinafter, the magnet 92 is energized periodically following the setting of pins 17 in accordance .with a code of signals to be transmitted as described above. Energization of magnet 92 moves the plate 88 to the left against-the action of springs 96 releasing the tooth 63 from engagement'with the'fixed-ratchet and releasing the power stored in spring 58 for rotating shelf 62 through post 59. The feeler I r cranks 86 pivotallv mounted onthe slidable plate88 are moved to the-left therewith and as they move from the storage pins 17, any

" 0f the contacts 82 and- 83 previously engaged are disengaged. As the tooth 63 disengages a tooth of the fixed ratchet 64, a spring tooth 98 pivoted at 99 on the slidingplate 88 en'- gages a toothon the ratchet 64. The spring 58 now rotates the table 62 until the spring tooth 98 engages both its own stop 100 and a tooth of the fixed ratchet 64; thisrotation' V bein'g'a suflicientangular distanceto. bring too base 102. -mounted at 104 is held against its back stop the cranks 86 into operative relations with a new set of pins.

The magnet 92 is thereupon deenergized and ,tensioned springs 96 operate to restore the slide plate 88 to its position at' the right shown in Figure 1. As the slide plate 88 moves to the right, the lower portion 89 of each of the feeler cranks 86 moves toward its associated pin 17 If the associated pin is in an elevated position as shown in Figure 1, it is in the path of the feeler crank and ob- 'structs its movement. The feeler crank 86, when it engages the pin 17 in its movement to the right is rocked about its pivot 87 and moves its associated spring contact 83 into' engagement with the contact 82. If on the other hand the pin 17 has been left in the lower position, it will not be in the path of the feeler crank 86 as it moves to the right and the contacts 82 and 83 will remain .disengaged. While the feeler cranks are iii operation or right end position, a distributor rotates as will be described in iietail herein after to transmit the codecombination or impulses in accordance with the operation of contacts 82 and 83.

Following the transmission of this code the magnet 92 is again energized and the slidable plate 88 moves to the left, tensioning the springs 96. The contacts 82 and 83 previously engaged, are now disengaged as the feeler cranks 86 rotate counter-clockwise about their pivots 87 and disengage-the pins 17.

Simultaneously the tooth 63 disengages a tooth on the fixed ratchet 64 and the shelf 62 is-released for rotation under control of the spring 58 to position the feelercranks .86 opposite a new set of storage pins 17 as described above. Thereupon the magnet 92 is again deenergized and the springs96 again function to move the slidable plate 88 to the right for engaging the feeler cranks 86 with those pins 17 of the succeeding groupwhich have been moved to an elevated position, as described above. In this manner the code set upon the pins 17 are stored to later control the trans itting contacts 82 and 83.

It ofte happens that the operator sets up a code on the storage pins17 whichifor any reason he wishes to wipe out so as toprevent the transmission thereof. 9 I have provided a simple and practical arrangement which enables the operator to erase .any code setup on the storage pins before the code'- is trans mitted. As shown in-FiguresQ1 and 3, the shelf 7 carries in addition'to the setting up magnets 8, a wipeout magnet 101, suitably mounted on the shelf by means of the magnet An armature 103 pivotally 105 by means of the spring 106. The back stop 105 as is well known in the art may be adi'usted to various positions by the ad us tab e set screw 107 andlock nut 108. Piv

otally secured to the armature 103 at 109 is a about the pivot 114 and restores the group of pins 17 above which it is at the time positioned. These pins 17 have previously beenoperated to their upper positions in various combinations. As will appear more fully hereinafter, the shelf 7 with the electromagnet 101 may be rotated to a position for associating the pin wipe out number 115 with any group of storage pins17, for wiping out the code set up thereon.

Referring now to Figure 7, the electrical circuits for controlling the code storing and transmitting apparatus explained in connection with Figures 1 to 6 will now be described. It will be recalled that the shelf 7 carrying magnets-8 is rotated to position the pin operating arms 10 opposite successive groups of storage pins 17. In order to provide proper electrical connections to the magnets 8 while in rotation a plurality of rings 121, one for each of the magnets 8 are mounted on an insulated base 122 carried by the outertube 5 so that as the tube rotates, the rings rotate therewith. The rings 121 are connected by conductors 123 to 128 to their individual magnets 8 andmagnet 101 on the shelf 7 and by a conductor 129 to the common return clrcuit.

As the shelf 7 rotates, the magnets, rings and connections rotate therewith preventing twisting or injury to the conductors.

In operative relation with rings 121-are the individual brushes 131 which are connected by the conductors 132 to 138. Conductors 132-136 are connected in various combinations to contacts on the transmitting keys 141 to 143 mounted on the keyboard in any 'suitable manner. Although these key levers are disclosed diagrammatically, it Will be understood that they may be arranged on any conventional bank commonly usedsuch as employed in type bar typewriters. Each of the key levers 141 to 143 controls individual groups of contacts completing circuits over the conductors 132 to 136 for selectively energizing predetermined combinations of the I in setting magnets 8. Thus for ex amp e if the key lever 141 is o erated, a circuit is completed from groun through the key lever 141, contact 144 conductor 132, brush 131, ring 12, conducto'r 127, through the electroma etj8 connected to the con-- ductor 127 an over the common return conductor 129, to which it will be noted all the magnets 8 are connected, over the ring 121 and brush 131 connected to the conductor 129 and through battery to ground. "Similarly over the contact 145, an energizing circuit is completed over the conductor 1.33v to energizethe magnet 8, connected to the conductor 125. Operation of key .141, as will clear from the above description energizes the ma ets 8 associated with conductors 127 amf l25. As a further .example, closmg of key 142 completes energizing circuits for mazgnets connected to conductors 124, 126 and 12 sufiicient to position the lever arms in operative relation with a succeeding set I of pins 17. and simultaneously tensionin the spring 58 as, described in detail 'a ve. When therefore a key 141 to 143 is depressed, not only are combinations of the pin operating magnets 8 energized but the solenoid 41-. is energized preparatory for stepping the shelf 7 When the key is released, magnets 8- are deenergized and simultaneously magnet 41 is deenergized stepping the ratchet 27 to associate the lever arms 10 of the magnets I 8 with succeeding set of pins 17 and to store energyi in the spring 58 for rotating the 0 transmitting shelf 62. As shown in Figures 1 and 7- the shelf 7 carries'an arm 151arranged to normally engagespring contact 152 to hold spring con.-

/ tacts 152 and 153 disengaged. Contacts 152 and 153 are riveted to a bracket arm 154 carried on theshelf 62. As shown when the pins 17 have no code stored. in them, the shelves 7 and 62 have-a fixed relative position at which arm 151engages spring con tact 152. Whenthe shelf 7 makes --its first.

In addition a common-return conductor 173 to the contact 152 controlled by the arm-151' as described above and the 9 rings .174 are connected'to. the striker 177 mounted on the shelf 7.- The striker 177' is arranged to engage contact 176. whenl-substantially all of the pins 17'have been set and it is accordingly desirable to warn the operator of this condition, This is accom It'will be noted that each of the keys con- 27 thus' rotating the shelf 7 a distance 208 oneend of which is secured to the armature and other end to the frame (not shown),

to-be described in detail ereinafter.

Each of the rings 163 are provided with individual brushes 181, connected by the conductors 182 to 186 to their individual segments 187 to' 191 on the distributor 192.. In addition to these segments, the-distributor 192 is provided with a stop segment 193 and a start segment 194. A continuous ring 195 is connected to the signalling line 196 extending to the remote station and is su'ccessively connected to the individual segments I87191 by brushes 197 carried by and rotatable with shaft 198. In addition there issecured to cam shaft 198 a cam member 199. A spring contact member 201 properl supported is normally in engagement wit contact 202 while its cam follower 203 is under I the depressed portion. of cam 199.'

' The brush arm 197 is normall held from rotation by the engagement 0 the armature extension 204 with the shoulder 205, of 1 the cam 199. The armature 206 pivotally mounted at 207is normally held by the spring '90 in a position so that armature extension 204 engages the shoulder 205 of the cam 199. An electromagnet 211 controlling the operacamis energized periodically in a manner to be described in the following r When, as described above, a key such as 141 is operated and a combination of the magnets v8 are energized, the rotation of the shelf 7 will move the arm 151 from engagement with the spring contact 152 and contacts 152 and 153 will close. An energizing circuit' is thereupon completed for ma ets 92 and 211 in series from ground throng the start magnet 211 over conductor 212 through the normally closed contacts 201 and 202 conductor-213 to the brush associated with ring 172 over conductor 17 3 contacts 152 and 153 in series to the .electromagnet 92, 'con-' ductor 156 and ring 157 to battery and ground. Inasmuch as the contacts 152 and 153 will not close except when the shelf 7 has moved from its normal position following the setting up of a codeon the pins17, it is clear that magnets 92 and 211 will ener' gize, only when a code has been set ready ailing line. Asa result of the energization of the mag- I net 92,"the sliding member 88, it'will be recalled is moved tothe left to permit a rov tation of the shelf 62, adistance sulficient to setthe feeler' cranks'j86. in operative posi- =tion' with respect to a succeeding group of pins. 17, the code for-thepreeeding set hav-, ing just been transmitted in the manner'to' be-described inconnection with the-succeed-- ing pins; Simultaneously with the energize-Q tion ofmagnet 92, magnet 211 is energized the exiao tension 204 disengages the shoulder 205 of the cam 199, and the brush 197 is released for rotation. .As the brush moves from segment 193 to the segment 194, the battery is re moved from the conductor 196. The opening of the line 196 is the start signal to which, as is well known in the art and need not therefore be described here, the remote station receiver responds to start the distributor thereat into rotation, for receiving the code to be transmitted.

Simultaneously with the movement of the brush 197 to the segment 194;, the cam tollower 203 of the spring contact 201 moves over the cam 199, and the contacts are opened, deenergizing the magnets 92 and 211. As a result of the deenergization of the magnet 92, the springs 96 move the sliding member 88, to the right and the crank feelers 86 are operated as described above to in turn operate the contacts 82 and 83 in accordance with the setting of the storage pins 17.

As now the brush 197 engages the first distributing segment 187, for example, a circuit is prepared over the lowermost contacts 82 and 83, Figure 7', from ground through battery, through the brush and ring 171 on the insulated block 159 over the common conductor 169, through the lowermost contacts 82 and 83, conductor 164, the uppermost ring 163 and brush 181, conductor 182 .over segment 187 ,continuous ring 195 and over the conductor 196 to the remote station. The above circuit is traced on the assumption that the lowermost contacts 82 and'83 were operated to their closed position .by the movement of the crank to the right, assuming again that the associated pin 17 was in its upper or operated position. Similar circuits willbe completed over the other segments as the brush 197 engages them, depending upon whether the contacts 82 and 83 connected therewith through the brush have been operated by their individual storage pins 17 A code is thus transmitted in accordance with the setting of thecontacts 82 and 83.

When the brush 197 has made one complete revolution and has returned to the position shown a start signal ,is transmitted over the line from battery through the segment 193, ring 195 and conductor 196. The apparatus at the receiving end operates in response to this impulse to bring the'distribubor thereat to a stop. At the same time the contacts 201' and 202 are again closed as the cam follower 203 reaches the depression in the cam 199, and the circuit traced for the magnets 92 and 211 is again completed.

Magnet 92 upon ener ization moves the slider late 88 to the le t permitting a rotation 0 the shelf 62 as described in detail above for positioning the feelers 86 in opera.

tive relation with a new set of storage pins aeratormagnet 92 is deenergized as described above,

to permit the movement of teeler cranks 86 to the right, for operating the contacts in accordance with the positioning of the pins 17, with which the teeler cranks at that time are associated. l'he cycle of operations described, will accordingly be repeated as long as contacts 152 and 153 are connected.

1f the operator fails to store any code on the pins 17, and the shelf 62 continues to transmit the previously stored code, these stored in the pins will ultimately all have been transmitted and the shelf 62 thereupon reaches the normal position with respect to the shelf 7 described above. The arm 151 thereupon again engages the spring contact 152 and contacts 152 and 153 disengage, opening the circuit for the magnets 92 and 211. These magnets thereupon remain deener ized until further code is stored in pins 17 uring this time thebrush 197 is held from rotation by the engagement of the extension 204C, with the shoulder 205 of the cam 199. The magnet 92 during this time does not move the slide plate 88 to the left to permit a rotation of shelf 62. The transmitter is thus held now operative.

On the other hand'gin event the operator stores the code on the storage pins 17 so fast that substantially all of them are set before the code transmitter succeeds in transmitting 7 these codes shelf 7 reaches a position relative to shelf 62 such that striker 177 engages and closes the contact 176. .A circuit is'the-reupon completed from the ground through battery ring 171 and the brush over the conductor 175, through the contact 176 closed, conductor 217 ring 17%, conductor 218 and through lamp 179 to ground. The illumination of the lamp 179 warns the operator that he has reached the limit of the storage device and should notattempt to store any more codes'until some of the codes already stored have been transmitted before setting up any additional.

In the event that the operator desires to wipe out some of the codes which have been stored,it is only necessary as described above, to energize the magnet 101. This is accomplished by the operation of keys 221 and 222. As a result of the operation of key 221 a circuit is completed through ground and battery over theconductor 223 through key 221, contact 224, conductor 138 through the brush and ring associated with the conductor 138, conductor 128 through the electromagnet 101, the common return circuit 129 through the ring and the brush connected thereto and conductor 137 to battery and ground. Theeneruse 7 gization of, magnet 101 operates the armature 103, and through-it the wipeout pull bar 110 andarm 112-rocking the wipeout lever 115 in aclockwise direction to restore the operated pins 17 to their non-operative position.

Simultaneously with the energization of the magnet 101, and over a parallel circuit an energizing circuitis completed for the magnet 56 over the contacts 224 and conductor zation of the solenoid 41 o'perates the bell crank 34 removing the tooth 34'of pawl 32 from one of the teeth of the'ratchet 27 simultaneously with the removal of the tooth of the pawl 51 from the ratchet 27. The ratchet 27 is thereupon rotated in the reverse direction by energy stored in the spring 58 operating through the outer tube 5.v The complete movement ofthe pawl 51 moves the tooth 225' of the pawl to engage a tooth on the ratchet 27 for stopping the rotation of the tube after it has moved a distance of a half tooth-pitch. As a result this rotation in the reverse direction of the outer tube 5, the shelf 7 isrotated and with it the magnet 101 and its associated wipeout levers for ositioning them in operative relation with t e preceding storage pins. This may be repeated as often asdesired, by maintaining key 222 closedand repeatedly operating key221 until all of the storage pins 17 are restored to normal ornon-operated position.

Although in the I resent modification, the

' wipeout will reset a l of the pins over which as described above..

it passes, it willfbe clear that it can 'be arranged to he stepped back without wiping out all of the pins, but can'be directly controlled by the operator to wipe out only certain groups of stored codes.

It will be clear that if desired, an additional ke may be provided for preventing operation of the transmitting apparatus shelf 62, while the wipeout function is being exercised In addition to the 'manu'all operated wipe out feature, describedabove, t e operated pins 17, must be restored to normal non-operative position, after-the code individual to.

their setting has beenj'transmittedjust .preceding the re-operation of these pins in acin front of the setting levers. lQon the shelf 7. As the cam 231, moves over the operated pins 17, they are moved to their 'non operative position bythe cam.
