ATTORNEY Patented Mar. 7, 1944 TELEGRAPH SYSTEM AND APPARATUS Philo Holcomb, Jr., Great Neck, N. Y., assignor to The Western Union Telegraph Company, New York, N. Y., a corporation of New York Application March 7, 1942, Serial No. 433,774

' 27 Claims.-

This invention relates primarily to telegraph systems and apparatus therefor, and more particularly to a system and apparatus which may, for example, be used for relaying signals through a central oflice wherein the signals may be stored for variable lengths of time.

It is impractical to establish a direct connection between incoming and outgoing channels at a telegraph central office, as the various channels may operate at different speeds or operate on different codes, and such an arrangement would require a large number of facilities which might not be warranted. Accordingly, in telegraph central offlces it is necessary to provide means for receiving signals over one channel and store the same before they are routed to and then retransmitted over the proper outgoing channel.

- The present invention is a continuation in part of a copending application filed July 8, 1939, Serial No. 283,334, now Patent 2,275,436, of March 10, 1942, and entitled Telegraph system and apparatus therefor. In the above application apparatus is shown and described whereby received signals operate mechanism to align two different types of mechanical elements, such as two different sizes of balls, in storage tubes whereby the two diiierent sizes of balls represent according to a predetermined plan the received signals. The above-mentioned application also shows means and apparatus whereby the aligned balls of the two different sizes control transmitting means to subsequently transmit to an outgoing line signals representative of the stored balls. The present invention is directed to apparatus which may cooperate with the apparatus of the above-mentioned application whereby the balls arranged in any one of a plurality of tubes may be physically transferred or conveyed to any one of a plurality of other tubes. By this apparatus a message received over any one of a plurality of incoming circuits is stored in a primary storage means or tube and thereafter transferred to a secondary storage tube to control the associated transmitting means associatcd with any one of a plurality of outgoing circuits.

Accordingly, it is one of the primary objects of the present invention to provide means whereby any one of a plurality of alignments of mechanical elements having difierent characteristics arranged to represent messages and/or other information may be conveyed to and associated with any one of a plurality of transmitting means.

In connection with the above, it is another object of the present invention to provide one mechanism which may be manually controlled to transfer the arranged mechanical elements and another mechanism which is automatically controlled.

Another object of the present invention is to provide means whereby the two different types of mechanical elements representing one message in a storage tube may be separated from the mechanical elements representing another message.

Another object of the invention is to provide means for determining which one of a plurality of secondary storage tubes a group of balls should be associated with and for depositing the balls in the desired storage tube.

A still further object of the invention is to provide means whereby one group of balls, which for example may represent an urgent message, may be associated with the transmitting means ahead of another group of balls which may represent a, less urgent message.

The above and further objects of the invention will be more apparent in the following detailed description thereof when taken in conjunction with the accompanying drawings, in which:

Fig. 1 is a diagrammatic representation of the elements comprising the present invention together with some of the electrical circuits;

Fig. 2 is an enlarged detailed sectional view showing the construction of a valve employed in the apparatus;

Fig. 3 is a sectional view taken on line 3--3 of Fig. 1;

Fig. 4 is a diagrammatic representation of the elements and control circuits of a modification of the invention; and

Fig. 5 is a side view of one of the mechanisms of Fig. 4.

Referring now to the drawings, and particularly to Fig. l, the rectangle II includes the elements of a so called receiving unit. In the preferred embodiment of the invention the receivin unit I I includes a line selector l2, which may be of the well-known Gill type, and a ball selector l3, which may be similar to that disclosed in Figs. 5 to 8 of the above-mentioned copending application. The receiving unit is controlled in accordance with received signals which are received over an incoming line circuit M.

The Gill selector l2 includes a magnet 16 which is connected to the line circuit and a set of contacts H. The selector operates in response to a predetermined code group or several predetermined code groups to close the contact set 11.

of balls in the storage tube 22 represent the sig nals received over the line circuit M.

In accordance with the operation of the invention, an end-of-message signal is transmitted following each complete message. The end-of- [message signal is eiiective to operate the selector |2 to close the contacts I! which energizes the solenoid l8. The energization'of the solenoid l8 draws a shuttle 23 to the left. The shuttle 23 rests upon a support 24 and has two vertical holes 26 and 2'l therein. Th hole 21 is normally in line with the lower end of the storage tube 22 and with th upper end of a so-called primary storage tube 28. The hole 26 in the shuttle 23 is normally positioned in a line with the discharge end of a supply tube 29, which contains therein balls 3| which are difierent in size from the marking and spacing balls selected by the ball selector l3. .The preferred arrangement is to have the balls 3|, which may be called end-of-message balls, larger than the marking and spacing balls. The movement of the shuttle 23 to the left deposits the end-of-message ball therein in the primary storage tube 28. As the shuttle 23 is operated only after the receipt of the end-off-message signal, the end-of-rnessage balls 3| will be deposited in the primary storage tube 28 only at the'end of a message. Thus, the larger balls 3| separate the message groups of balls in the primary storage tubes 28.

Other receiving units such as 32 and 33, similar to the receiving unit II, are controlled by signals received over associated incoming circuits 34 and. 36, respectively; The

receiving units

32 and 33 function in the same manner as the receiving unit II to deposit the two different sizes of marking and spacing balls in their associated primary storage tubes 28 with each message group of balls separated by an end-of-message ball such as 3|.

The lower ends of all of the primary storage tubes 28 terminate in a horizontal plate section 31 of a frame member 38 with the lower ends of the tubes arranged preferably in a circle on the plate 31. Preferably, the lower ends of the primary storage tubes 28 or the section thereof that terminates in the plate 37 are of glass or some other suitable transparent material. The reason for having the lower ends' of the primary storage tubes transparent is so that an attendant may see the presence of the balls in the tube, particularly at the lower ends thereof. The length of the primary tubes 28 is such that a considerable number of balls may be held therein to represent several messages.

Pivotally attached to the underside of the plate 31 by means of a bolt 39 is a disc member 4|. The disc member 4| has handles 40, by means of which the disc may be rotated relative to the plate to change theposition thereof. In a radially extending groove in the upper side of the disc 4| is a shuttle 42 with a vertical hole therein or sufflcient size to permit the passage therethrough of th larger end-of-message balls 3|.

The movement or the shuttle 42 is controlled by a solenoid 43 through a link 44, the circuit to the'solenoid being controlled by a switch 45. With the solenoid 43 in its deenergized condition, the shuttle 42 is to'the'left,- as shown in Fig. 1, with the hole therein directly beneath the lower end of a primary storage tube'28. With the shuttle in this position' the hole is also in alignment with the upper end of a tube 46 fixed to the disc for rotative movement therewith. The size of the tube 46 is such that passage of the larger end-of-message ball 3| therethrough is not permitted, and accordingly, the passage of the balls from a primary storage tube 28 into the tube 45 is prevented when an end-of-message ball 3| reaches the shuttle 42. This indicates that a complete message has passed into the tube 46.

The primary storage tubes 28 are located in a circle on the plate 3'1 with the bolt 39 at the center of the circlefa'nd by'rotating the disc 4| the shuttle 42 and the upper end of the tube 46 may be positioned beneath the lower discharge end of any one of the primary storage tubes at a time. With an end-of-messageball 3| in the shuttle '42 and marking and spacing balls 41 and- 48, respectively, located thereabove, the removal of the end-of-message ball permits the marking and spacing balls to enter the tube 45. The end-' of-message ball 3| is removed from the shuttle by energizing the solenoid 43, whichmoves the end-of-message ball toward the center and, when over a tube 49, permits the end-of-message ball to drop therein. The tube 49 leads to a container 5| for catching the end-of -message balls 3|. The return of the shuttle 42 to its outer positionopens the passageway between the upper primary storage tube 28 to the tube 46. The detailed manner of operating the solenoid 43 to control the passage of balls from the primary storage tubes 28 into the tube 45 will be pointed out hereinafter.

The lower end of the tube 46 terminates in a flange 52 on the upper end of a reading unit indicated in general by reference numeral 53. The reading unit 53 is stationary, and a. bearing 54 permits-the tube 46 and disc 4| to be rotated relative thereto. The reading unit consists of means whereby an operator may read a part of the message represented by a group of balls to determine its destination. The destination of a message would be indicated preferably by the first few code groups of balls and by reading the same the operator would know where to route the entire message group so that the message group could control the proper transmitting means to transmit over the desired outgoing circuit.

Q A tube 56 extends through the center of the reading unit 53 and has the upper end thereof positioned directly beneath the lower end of the tube 46. A section 51 of the tube 56 is arranged so that the lower part thereof maybe swung a slight amount to the left. This brings the discharge end of the section 51 into operative relation with a disc 58 comprising a part of the reading unit. The upper end of the tube section 51 remains in line with the lower end of the tube 46 at all times, and the pivoting of the tube section 57 is controlled by a magnet 59 through a link 6|. A switch 52 controls the energization of the magnet 59. The above-mentioned disc 58 is carried on a shaft 53 suitably journaled in the reading unit and driven through a friction clutch (not shown) from a suitable source of power. When the apparatus embodying the present invention is employed in conjunction with a fiveunit signaling code or the well-known Bordeaux code, the disc 58 has five stepped notches 84 in the periphery thereof. The notches 64 are arranged in approximately one-half the periphery of the disc 58 and are of such a size that a smaller spacing ball 48 is permitted to enter to substantially the full depth of a notch, while a larger marking ball 41 is permitted to enter only a part of the depth of the notch. Thus, the larger marking balls protrude an appreciable amount from the notches in the disc, while the smaller spacing balls do not.

Also positioned on the frictionally driven shaft 63 is a cam 68 which has associated therewith a set of contacts 61. A stop disc 88 on the shaft 83 controls the rotation thereof and cooperates with an armature 89 operated by a magnet A switch 12 controls the energization of the magnet ll and, when the magnet is energized, the armature 88 is operated to disengage the upper end thereof from the stop disc 88. thereby permitting the shaft 63 with its attached elements to rotate. On the deenergization of the magnet II, the armature 89 is positioned to engage the stop disc 88 and stop the same in its normal stop position, such as that shown in the drawings. The cam 86 on the shaft83 is arranged to momentarily close the associated contacts 87 Just before the shaft reaches its rest position. In the rest position of the shaft 83 the contacts 81 are open.

vIn operative relation with the disc 58 are a set of five pivot arms 13, the free ends of which are adapted to sense the different sizes or types of balls in the notches 84 in the disc. When the free end of a pivot arm 13 engages a larger marking ball in a notch 64 in the disc, it contacts the ball and effects'the closing of an associated set of contacts 14. The free end of an arm 13 engaging a small spacing ball in the disc permits its associated contact set .14 to be open. Each of the contact sets 14 is connected by individual conductors such as 18 to associated magnets 11 in a recording mechanism represented by the dotdash rectangle 18. The recording mechanism 18 may be of any of the well-known five selecting magnet types and includes a print magnet 19 connected by a conductor 8| to one of the terminals of the contacts 61. the other terminal of which is connected to potential. .The closing of the contacts 81 applies potential over the conductor 8| to the print magnet 18 in the recordin mechanism l8 and also to one of the terminals of each of the contacts 14. If any of the contacts 14 is held closed by the presence of a marking ball in operative relation with the free end of the associated pivotable arm 13. potential from the con-. tacts 81 is also applied to associated ones of the selecting magnets 11. Thus, the selecting magnets are selectively energized in accordance with the different sizes of the group of five balls in the disc 58, and the operation of the print magnet 18 concomitantly therewith effects recording of a representative character by the recording mechanism. Accordingly. for each group of live balls removed from the tube section 51 by disc 86 pivotally mounted on a bolt 81 extending from the center of a stationary circular plate 88 secured to the frame 38 and forming a part thereof. The disc 86. which is circular, may be rotated on the plate 88 by means of radially extending handles such as 89.

The lower end of the tube 82 extends through the plate 88 and is flush with the bottom side thereof. Arranged around a circle and extending up through the plate 88 with the upper ends thereof flush with the upper side of the plate are a series of secondary storage tubes 9|. The upper ends 'of the storage tubes 9| are the same radial distance from the-center of the plate 88 as is the lower end of the tube 82, and accordingly by rotating the disc 89 which has therein the lower end of the tube 82, the said lower end may be lined up with the upper end of any one of the secondary storage tubes 8|. In the preferred embodiment, the secondary storage tubes 9| are of sufficient length to store balls representing several messages. The tube 9| terminates in socalled transmitting devices which are operative to remove the balls stored in the tubes 9| and transmit representative signals. Such transmitting mechanisms are represented by the rectangles 92 and have outgoing circuits such as 93 associated therewith. The transmitting devices 92 may be of the type disclosed in the above-mentioned copending application and shown in Figs. 9 to 15 thereof. Mounted on the plate 88 so as to be rotatable therewith is a magnet 94 which on energization thereof through its armature 98 is effective to insert a pin 81 in the tube 82 adjacent the lower end thereof. With the pin 91 in the tube, the passage of balls from the tube is prevented, and the operation of magnet 94 permits the disc 88 to be rotated to any desired position without depositing balls in the tubes over which the disc 58. a character representative of the it may pass. The energization of the m gnet 94 is controlled from a switch 98. The detailed manner in which an operator controls the above-described mechanlsms to transfer a group of balls representing a message from a primary storage tube 28 to the desired secondary storage tube 9| vill now be described.

Let it be assumed that a message group of balls has passed through the device, and the large end of-message ball is in the shuttle 42, and that one or more other message groups of balls are in one or more of the other primary storage tubes 28 waiting to be transferred to their proper secondary storage tube 9|. The operator is aware of the balls in the primary storage tubes 28, as they may be seen through the transparent lower section thereof. The first operation for the operator is to close the switch which moves the shuttle 42 toward the center of the disc and places a solid section of the shuttle beneath the lower end of the primary storage tube 28 with which it was last associated and deposits the larger end-of-message ball 3| that was in the shuttle in the container 5|. With the shuttle 42 in its operated position. none of the primary storage tubes can be connected or a passageway completed from any of the primary storage tubes to the tube 48. The operator then rotates the disc 4| to bring the upper end of the tube 48 beneath the desired primary storage tube 28. Preferably. each primary storage tube has a designation such as BT, NC, ZT, etc. thereon. and similar designations are inscribed on the disc 4|. These desi nations inscribed on the disc 4| are so arranged that. when the upper end of the tube 48 is associated with a particular primary storage tube,

the corresponding designation on the disc M will be associated with an indicating mark such as an arrow 99, Fig. 3, on the plate 31. Thus, the operator can tell when the tube 46 is correctly positioned beneath the desired one of the primary storage tubes 28.

The next operation is the closing of theswitch 98, which blocks the passage of th lower end of the tube 82 and is followed by the closing of the switch 62, which swings the discharged section of the tube section 51 to the left and into operative relation with the periphery of the disc 58.

The operator then opens the switch 45 which is effective to permit the return of the shuttle 42 to its outer position and thereby establishing a passageway between a primary storage tube 28 and the tube 48 located therebeneath. The balls thereupon enter the tube 46 and pass therethrough to the tube section 51 where the first one encounters the solid portion of thedisc 58 and is stopped thereat. The operator then closes the switch 12 to energize the magnet 1| and effect release of the shaft 63, which rotates, and the disc 58 rotating therewith during the first revolution thereof removes the first five balls, or a. code group of balls, from the lower end of the tube section 51. While the code group of balls and the disc 58 are in operative relation with associated pivotable members 13, the cam 66 momentarily closes the contacts 61 to apply potential through the print or recording magnet 79 in the printing mechanism and also the ones of the selecting magnets 11 whose associated pivotable arms 13 are associated with the larger marking balls.

The recording mechanism 18 records a character represented by the first group ofballs removed from the tube section 51 and continues to record characters represented 'by other groups of balls removed from the tube section as long as the magnet 1! remains energized to permit rotation of the shaft 63. After a sufficient'number of characters have been recorded by the recording mechanism to enable theoperator to determine the destination of the accompanying message group of balls, the first few characters being employed to determine the destination of the mesan indicating mark or arrow I00 on the stationary disc 88. Thus, when the proper indication on the disc 86 is associated with the indicating arrow I00, the lower end of the tube 88 is associated with the upper end of the corresponding secondary storage tube 9 I. When the disc 86 is properly positioned, the operator opens the switch 98 which controls the magnet to permit the passage of the balls to the proper secondary storage tube 9|. Only a single message group of balls is permitted to pass through the mechanism at a time, as the large end-of-message balls 3| placed in the primary storage tube 28 at the end of a message prevent passage of balls representing a second message through the mechanism until after the end-of-message ball has been removed. Thus, a message group of balls from any one of the primary storage tubes 28 may be passed through the mechanism and deposited in any one of the plurality of secondary storage tubes 9!, and as the passage of the balls through the mechanism requires but a short interval of time, the mechanism is capable of serving a plurality of primary and secondary storage tubes.

In telegraph practice certain types of messages have preference to a circuit over other types of messages, and the mechanism provides means whereby a group of balls representing a preferred message may be associated with the transmitting device 'before a group of balls representing a deferred message, even though the group of balls representing the deferred message may be deposited in a storage means such as the primary storage tube 28 ahead of the group of balls representing the preferred message. The reading unit 53 in conjunction with the printing mechanism 18 indicates when the beginning of a deferred message is in the mechanism. and if a. deferred message is followed by a preferred message, the operator before opening the switch 98 operates a valve I01, Figs. 1 and 2, to complete a passageway adjacent from the upper sage, the operator opens the switch 12 to stop the shaft 63 from rotating and,'while the disc 58 is making its last revolution, the operator opens the switch 62. During the last revolution of the disc 58, the last group of balls removed from the tube section 51 is deposited in the tube 55 which joins the tube 56 adjacent the lower end thereof. Thus, the groups of balls which were read or associated with the disc 58 are deposited in the tube 56 in the same order in which they are removed from the tube section 51, and before the disc58 can rotate to remove another group of balls from the tube section 51 the latter is swung to the right and the balls therein will pass down through the tube 58, following the balls deposited therein from the disc 58.

As the

switches

62 and 12 must be operated in definite timed relation to one another, an interlocking means which properly times the operation thereof may be employed. The operator reading the destination of the message represented by the group of balls, the first part of which is in the

tubes

82, 56 and 46, then rotates the disc 86 to bring the lower end of the tube 82 over the proper secondary storage tube 9|. The proper location of the disc 85 is facilitated by the employment of indications such as BL, TB, MR,

etc. on the movable disc which cooperate with end of the secondary storage tube. 9| to a deferred tube I02. Accordingly, when the'pin 91 is subsequently removed from the lower end of thetube 82, the balls will pass into the deferred storage tube I02 associated with the particular secondary storage tube 9| and be held therein by a stop l03 adjacent the lower end thereof. The stop I03 consists of a pin adapted to enter the deferred secondary storage tube I02 to prevent the'passage of the balls therethrough and from re-entering the secondary storage tube 9i When the entire message representing a deferred message is stored in the deferred storage tubel02, the valve I0! is operated to establish a direct passageway between two sections of the secondary storage tube 9| such as shown in Fig. 2. The operation of the mechanism as described above then permits the group of balls representing the preferred message to be associated with the transmitting device such as 92 ahead of the group of balls representing the deferred message in the deferred storage tube I02. A deferred storage tube I02 with its associated elements may be associated with each one of the secondary storage tubes 9! to enable the storage of a deferred message.

As the

magnets

43 and 94 are on rotatable elements and the control means therefor preferably stationary, suitable commutator means may be provided, and all the controls of the complete 1 the improper sequence of operation thereof by any of a number of well-known means.

In the heretofore described arrangement the ball transferring device was manually operated. Without substantially changing the mechanisms, automatic reading and transferring may be employed in the manner hereinafter described. The automatic arrangement shown in Fig. 4 employs differential devices to. indicate the number of large end-of-message balls in each primary storage tube 20, together with a contact device which is added to the ejector shuttle to indicate the arrival of end-of-message balls at the distributor. Brush arms I15 and I86 are added to the upper and lower discs, respectively, and their brushes move over fixed outside rings. The developed form of the commutators and brushes is shown in Fig. 4. Notches cut in

discs

41 and 86 permit the stop magnet armatures I50 and I5I to arrest rotation at points when

tubes

46 and 82 are correctly aligned with the primary and secondary storage tubes 28 and SI. The upper and lower discs are rotated independently of one another by suitable means such as friction clutches indicated generally by reference numerals I52 and I53, respectively. Added contacts are provided for cam 66 and relays I54 with multiple contacts connected in the well-known Tree circuit replace the selecting magnets 11 of the printer 18 in Fig. 1. Three additional relays are added, the function of which will hereinafter be described.

Let it be assumed that the system is clear of traffic and that all primary and secondary storage tubes 28 and SI respectively are empty. At this time the T bars I55 of the differential storage indicators, of which there is one for each primary storage tube 28, are in the positions shown, and their associated contacts .I56 closed. All segments I51 receive direct battery through contacts I56 and the right hand or high current coil of relay I58. Since segments I51 are substantially continuous, contacts I59 of relay I58 remain closed, and battery is applied through said contacts to the upperdisc stop magnet I60 and the shuttle magnet 43. The operation of the armature I50 of the stop magnet I60 withdraws it from a notch IBM in the upper disc M and permits the upper disc to rotate. The operation of the shuttle magnet 43 presents a plane surface to the primary storage tube 28.

With relay I58 energized, a condenser I6I connected to a tongue I63 thereof is in a discharged condition, it being discharged through a resistance I62 and the make stop. Cam 66 and stop arm 68 and reading wheel or disc 58 will be in the position shown in Fig. 2. The armatures of the code relays I54 are locked in the positions of the previous selection, and current passes from cam contact I64. through the Tree circuit of relays I54 through the segment I61 corresponding to the previous setting of tube 82 through the stop magnet I65 to ground. As contacts I66 and I61 are open, the magnet 59 for operating the diversion tube 51, Fig. 1, and the magnet 94 of exit valve pin 91 are deenergized.

Now let it be assumed that the trafiic signals begin to appear on one of the circuits, causing the operation of the magnet I9 of its ball selector and magnet I6 of its Gill type selector. Because the Gill type selector does not receive an operating combination in the course of an ordinary message its contacts I1 remain open. Marking above the rotatingupper disc 4I. when the distant operator completes the message, an end-ofmessage signal is transmitted which causes contacts I1 to close, which in turn control the operation of the magnet I8 to cause a large end-ofmessage ball to be injected in tube 28, as heretofore described. A magnet I68 is connected in series with the magnet I8 and operates therewith. On the return of the armature of magnet I68 to normal, it causes a gear I69 of the storage indicator to rotate in a counterclockwise direction, as viewed in Fig. 5.

The storage indicator comprises a T-shaped bar I55 rotatable in two fixed bearings I10. Three beveled gears I69, HI and I12 are loosely mounted on the T bar, as shown, and arranged in the usual manner of differential gear mechanisms. The outer surfaces of gears I69 and "I have ratchet teeth formed therein, which cooperate with pawls I69a and Illa operated by the armatures of magnets I68 and I13 so that the gears are rotated or stepped on the back-stroke of the armatures. Holding pawls such as I14 retain the gears in their stepped positions. When there are no big end-of-message balls in the associated primary storage tube 28, the T bar I55 of the differential storage counter is in the position shown in Fig. 5, and its contacts I56 are held closed. On a complete operation of magnet I68, gear I69 is rotated in a counterclockwise direction, as viewed in Fig. 5, and since gear Ill is assumed to be stationary at this moment (although this is not necessary), gear I12 is caused to rotate in such a direction as to raise the T bar I55, which permits the contact I56 to open.

resistance winding of magnet I13 reduces the current in the right hand coil of relay I58 to a value that is insufficient to hold the relay operated, and the contacts of the relay are therefore opened. Tongue I59 of relay I58 opens the circuit through magnets I60 and 43 to effect stopping of the upper disc II and the shuttle to return to its normal position. The shuttle returning to its normal position establishes a passageway for the balls representing the message stored in the primary storagetube 28 to the tube 46. The tongue of relay I58 contacting its break stop results in the charging of condenser I6I and the subsequent operation of cam stop magnet 1 I. This releases the shaft 63 for rotation, and during rotation thereof the cam 66 opens the con tacts I64 which effects deenergization of relay I19 and stop magnet I65. The deenergization oi the stop magnet results in the freeing of the lower disc 86 and the inauguration of its rotational search for the next stopping position.' In quick succession battery is applied to contacts I66 and I61, closing a circuit through the magnet 94 and the coil of a relay I8I. The energizetion of magnet 58, as hereinbefore described, diverts balls to the reading disc 58. When the apertures of the reading wheel are in the correct reading position, the code relay locking battery is removed from contact I82 and applied to the code relay operating common contact I83 through cam contact I84. Certain contacts in the group I85 determine that their corresponding unlocked relays are to be operated or held in the operated position when battery is again applied to locking contact I82 by further rotation oi cam 65. Al-

though five balls are shown in Figs. 1 and 2, the readingwheel may have apertures for six or any other number ofballs. .It is not essential that even multiples of. five be employed, as the balls which are not used are sent directly toward the secondary storage by tube 51. h

I When the cam shaft 63 rotates to its final position. as determined by 'cam 68, battery is reappliedto the Tree circuit through contact I6! and relay, coil I19. Magnet 94 is still locked up, and

its pin 91 prevents passage of the balls in the dis- 7 tributor to the ,second'ary'storage tubes until brush I86 finds the only segment in ring I81 with completed circuit through the Tree .to battery. ,,When-' th'is happens'relziy' I19 is energized, which opens thecircult to'the magnet 94 and effects de energization"of the same. A mechanicalpassag eway is thus opened through the distributor from a primary storage tube to the proper seconda'ry storage tube. and this passage is maintamed until the end of the message. When the big end-of-rnessa'ge. ball finally comes to the shuttle, its'greater diameter causes a metal U- "shaped spring I88 to expand and complete a circult through two fixed pin contacts I89 and I90. A circuit is thereby established from ground at the U-shap'ed spring I88 to battery through the left hand coil "of relay I58 to energize the same. Tongues I59 and I63 contacting their make stops effect discharging of condenser iii in preparation for the next cycle, and operation of the stop magnet armature I56 and shuttle associated with shuttle magnet 53. Thereupon the upper disc 4| begins to rotate, and as its brush I15 leaves segments IIa, low current magnet I13 is deenergized and gear III is rotated one ratchet tooth in a clockwise direction to cause contacts I55 toclose and shunt out low current magnet I73.

If no further messages are completed by ball,

selector I9 and terminated by big end-of-message balls, contacts I56 will remain closed and brush II5'will pass, but fail to stop, on segment I5la in the future. However, if more than'one big endof-message ball had been counted into the differential storage indicator before the first message had been properly discharged from the distributor, the bar I55 of the indicator would have been rotated counterclockwise by increments equal to the number of end-of-message balls in the primary'storage tube, and brush I would at the end of its next revolution again find contacts I56 in an open condition and would therefore stop on segment I510. for the distribution of another complete message.

A manuallyoperable switch I95 may be connected, as shown, with each of the make stops of the tongues of the Tree circuit of the fourth relay of the selecting relays I54. Switches such as I95 could by their position control which one of two segments of each pair on the ring I81 will 7 sage would be deposited.
