Referring rst to Fig. 1, a plan view of the invention is shown adapted to operate for use'in storing signals having five variable impulses. In the arrangement shown there are two double storage units and one single storage unit, a unit as hereinafter pointed out comprising a set of mechanical elements or selecting pins with mechanisms for moving the same from normal to operated positions in accordance with a signaling impulse and for subsequently controlling the transmission of a representative impulse of one line condition or another in accordance with the position of the mechanical element. In the invention all the storage units are substantially similar and comprise similar parts, and in the following description Vwhere the operation and arrangement of the elements of a single storage unit is described, the description thereof applies equally well to all of the storage units. The storage units are so controlled, as hereinafter pointed out in detail, that one unit, such as the first, stores all the first signaling impulses of the code groups, the second storage unit all the second signaling impulses of the code groups, etc., for the five storage units. As shown and described in the following paragraphs, the invention is arranged to store signal groups composed of i'lve units or impulses and as will be obvious, by changing the number of storage units, such as increasing the number to six, six unit code groups f could be stored.

In the drawings, and particularly in Figs. l and 2, reference numeral indicates a base plate upon which the various elements of the invention are located. Fixed to the base are bearing posts I2 which, together with bushing clamping members |3, support and clamp a plurality of bushings such as I4 in fixed position. The bushings I4 have a shaft |6 journaled therein, adapted to rotate in a manner hereinafter pointed out. Fixed to opposite sides of each bearing post I2 and clamping member I3 by screws, such as I1, are two circular discs I8 and |9, and arranged around thediscs I8 and I9 adjacent the periphery thereof are rings of holes 20. The disc I9 has onering of holes therein at a fixed radius, and the disc I6 has two rings of holes therein. Extending through Vtheholes in the discs I8 and I9 are the movable mechanical elements or selecting pins 2| which are positioned as hereinafter described into one of the other of two positions to represent receive signals. The selecting pins 2| are preferably constructed of spring wire and have one or more complete turns adjacent the center with'the free ends extending substantially parallel, such as the construction of a safety pin. In fact, it has been found that safety pins with the head and point removed or cut off work very satisfactorily as the selecting pins. Referring to Fig. 4, which shows a selecting pin 2| at an enlarged scale, it will be noted that the two

arms

22 and 23 thereof are of different length. The arms of the selecting pins 2| extending through the holes in the discs |8 and I9 form a ring with the arms substantially parallel with the shaft I6. The longer arm 22 of the selecting pins 2| extends through both discs I8 and I9, whereas the shorter arm 23 extends only through the disc I8. The tendency of the

arms

22 and 23 of the selecting pins 2| to open or spread apart prevents free movement thereof in the discs I8 and I9 and' provides the biasing effect for retaining them in either one or the other of their two positions. In Fig. 4 the selecting pin 2| is shown in its normal unselected position by the full lines thereof, and in its selected position by the dotdash outline. The manner of selectively operating or moving a selecting pin from its normal to its selected position and the resetting thereof back to its normal position will be pointed out hereinafter.

Mounted on the shaft I6 for rotation therewith by means of keys 24 are collars 26. The collars 26 are movable along the axis of the shaft within predetermined limits, as pointed out hereinafter, but by means of the keys 24 invariably rotate with the shaft I6. Adjustably, attached to the collars 26 by screws 2l, Fig. 8, extending through slots such as 28 are arms 29. The arms 29, hereinafter referred to as the setting-up arms, extend radially from the collars 26 and have projections. 3|, Figs. 1, 2 and 4, at the free ends thereof which extend axially of the shaft I6. The projections 3| are in operative relation with the left hand end, as shown in Fig. 4, of an associated set of selecting pins 2| and serve to move the pins from their normal to their selected or operated position in accordance with representative signaling impulses. Formed in the collars 26 are circular grooves 32, and rollers 33 carried in the upper ends of forked or bifurcated arms 34 of bell cranks 35 engage radial surfaces of the grooves 32 to move the collars 26 back and forth along the shaft |6. The bell cranks 35 of which the arms 34 form a part have horizontally extending arms 36 which serve as armatures for associated selecting magnets 31 in operative relation therewith. The bell cranks 35 are pivotally mounted on pins such as 38 supported by brackets 39 attached to the base II. Springs 4|, attached to the arms 34 of the bell cranks 35 and to the brackets 39, normally hold the bell cranks 35 in their retracted position against associated stops 42. With the bell cranks 35 in their retracted position the projections 3| at the ends of the setting-up arms 29 are clear or a little to the left, as shown in Fig. 4, of associated sets of selecting pins 2|.

The setting-up arms 29 are adjusted by means of the screws 21 relative to the collars 26 so that with the shaft I6 at rest in a normal stop position each of the projections 3| are in alignment with a selecting pin 2| in an associated storage unit. Therefore, when the selecting magnets 3l are selectively operated in accordance with a received code group, operating impulses being distributed thereto by a distributor hereinafter described, the energized ones of the magnets 31 cause associated collars 26 to move toward asagradessociated` discs I8, and in so doing the projections 3| on the setting-up arms 29Y slide associated selecting pins 2| to operated positions. The ends of the arms 23 of the selecting pins'2l coming into engagement with the discslS limit the movement thereof to an operated position, and in such an operated position the ends of the arms 22 extend an appreciable amount beyond the outside face of the discs I9. Thus, aset of selecting pins 2|, one in each of the storage units, are set in operated positions or remain in their normal positions in accordance with a received code group. The selecting pins 2|, associated with the selecting magnets 31, that are not energized obviously remain in their normal unoperated positions. A y

After setting a set of selecting pins 2|, one in each storage unit, in accordance with one received code group of impulses, the shaft |6 is stepped to bring the projections 3| opposite the next set of selecting pins. The stepping of the shaft I6 is performed preferably by a stepping magnet 43, Fig. 6, horizontally mounted from a bracket 44 extending from the base Il. The magnet 43 has associated therewith an armature lever 46 L pivotally mounted on a pin 41 in the bracket 44 which carries on its upper end an operating pawl 48. The pawl 48 cooperates with teeth 49 on a ratchet wheel or disc I which is attached by a set screw 52 to the shaft I6 for rotation therewith'. A spring 53 holds the pawl 48 in engagement with the teeth 49, while another spring 54 moves the armature lever 46 and pawl 48 to their normal retracted positions on the deenergization of the magnet 43. An adjustable stop 1.

screw 56 determines the retracted position of the armature lever 46 and its attached pavvl 48. A spring biased retaining pawl 51 pivoted at 58 also cooperates with the teeth 49 of the disc 5| to prevent rotation of the disc and shaft I6 in a reverse direction as the pawl 43 moves to pick up another tooth. The movement of the armature lever 46 is limited by the back stop 56 so that on the energization of the magnet 43 the disc 5| will be rotated an amount equal to the'V distance between two consecutive teeth on the periphery thereof. As the teeth 49 on the disc 5| are equal in number to the number of selecting pins in the holes in the discs i8 and 9, each time th'e disc 5| is stepped one tooth the setting-up arms 29 move into operative relation with or opposite" the next selecting pin 2|. The magnet 43 is energized as hereinafter pointed out in` conjunction with each operation of the magnets 31, and accordingly the setting-up arms 29 are successively moved into operative relation with successive ones of the selecting pins 2|. Thus, the selecting pins 2| of each storage unitare operated from their normal to their operated positions or remain in their normal positions in accordance with received groups of code impulses.

and consecutive selecting pins or ele-ments in a storage unit represent, according to their position, corresponding impulses of succeeding code groups.

Th'e'manner in which the position of the selecting pins 2| control the transmission of representative groups of impulses and the distributing of operating impulses to the

magnets

31 and 43 will hereinafter be described.

In distributing the operating impulses Vto the selecting pin operating magnets 31 and timing the operation of the shaft stepping magnet 43 a distributor of the type known in the art as a multiplex distributor is employedr Although the inventionV is shown and hereinafter described as operatingin conjunctionwith. multiplex signals, it willi be' obvious that by changes apparent to those skilled in the art the invention could readily be employed to operate in vresponse to start-stop or simplex type signals and when operating in response to these simplex type signals the start and rest impulses would not necessarily have a storage unit asthese impulses are of uniform character for each code group. In Fig.`1`0y the multiplex distributor is indicated in generali by reference numeral 6| and comprises four rings 62 to 65 with a set of two brushes 66 and 61. The direction of movement of the brushes 66 andl 61 is from-right to left as indicated by the arrow,

and the brush 66 bridges the solid ring 62 with the segmented ring 63 while the brush 61 bridges the solid ring 64 with the segmented ring 65. Code groups of signals received over the line LI operate the tongue of a line relay 68 in accordance therewith and apply over a conductor 69 corresponding positive and negative impulses to the solid ring 62. The brushes 66 and 61 rotate in timed relation with the received code groups and' the brush 66 contacts the segments numbered I to 5 of ring 63 while potential in accordance with the successive impulses of each code group is applied to the solid ring 62. The segments-numbered to 5 of the ring 63 are connected by individual conductors such as 1| to one side of theA coils of individual relays such as 12, the other sides of which are grounded. Each of the relays 12 has a tongue 13, and all the tongues are connected in parallel by a conductor 14 to the make stop of a relay 16. Depending upon the polarity of the potential on the solid ring 62 at the time the brush contacts the segments numbered to 5 of the ring 63, the tongues 13'of the relays 12 are operated to either their left or right hand stops and accordingly the positions of the tongues 13 to one stop or the other represent a received code group of impulses. Following the operation of the relays 12 the brush 61 contacts a segment 11 of the ring 65 and applies potential from the g solid ring 64 over a conductor 18 to operate the relay 16. A tongue of the relay 16 has potential applied thereto and engagement thereof with its front stop applies potential over the conductor 14 to the tongues 13 of relays 12, The left hand stops associated with the tongues 13 of relays 12.

are connected by individual conductors such asv 19 through the coils of the selecting magnets 31 to groundfAccordingly, the magnets 31 associated with the tongues 13 on their left hand stops will be energized when the relay 16 is operated to apply potential to the tongues 13. The magnets 31 associated with the tongues 13 on theirright hand stops will obviously not be' operated on the energization of relay 16, as the circuits thereto are open at the tongues 13. Accordingly, the magnets 31 are operated in a combination representative of the received code group. f

Shortly after the brushI 61 passes from segment 11, it contacts a segment 8| of the ring 65 t0 apply potential-over a conductor 82 to the grounded stepping magnet 43. This causes operation of the magnet 43 and, as hereinbefore pointedr out, the stepping or movement of the setting up arms 29 into operative relation with the next set of selecting pins 2|. Thus, the setting up arms 29 are positioned opposite a new or succeeding set of selecting pins 2| to be operated in accordance with the next received code group of impulses.

A cutout arrangement such as those: welll known in the art' may be employed to open the circuit `supplying potential to the Vsolid ring 64 or the magnet 43 and relay 16 when no intelligence signals are being received over the line LI to prevent the stepping of the setting up arms 29 during idl'e periods of the line LI. Such cutout arrangements are well-known in the art, and as they form no part of the present invention the addition of circuits ldisclosing this feature would 4 unnecessarily complicate the drawings, and they are therefore omitted.

The manner in which a signal group of impulses representing the position or setting of a set of the selecting pins 2| is transmitted to a sending line and the elements for accomplishing this will now be described. In the double storage unit shown in section in Fig. 2 a sleeve member 83 is loosely mounted on the shaft I6 with the ends thereof in abutting relation with the bushings I4. The sleeve 83 being loosely mounted `on the shaft I6 permits th-e shaft and the sleeve to rotate independently of each other. The sleeve has adjacent its right hand end a flange, and clamped against the ange by a nut 84 in threaded engagement with the threaded left hand end of the sleeve are two

discs

86 and 81, together with three slip rings 88. The slip rings 88 are insulatively supported from one another, the

discs

86 and 81 and the sleeve 83 by insulating elements or rings 89. Associated with each of the slip rings 88 are individual brushes such as 9|, Fig. 5, supported from the base I I by a bracket member 92.

The disc 86 has formed in the periphery thereof teeth adapted to engage the teeth on a gear 94, Fig. 1, fixed for rotation therewith to a shaft 95. The shaft 96 is journaled in brackets such as 91 supported from the base II. Also fixed to the shaft 96 is a ratchet wheel 98, and cooperating with the teeth of the ratchet wheel 98 is an operating pawl 99, Fig. '7. The operating pawl 99 is pivotally carried at the upper end of an armature I| which is pivoted at its lower end on a pin |02 carried in a bracket member |83 supported from the base II. Associated with the armature lever IOI is a magnet |84 which upon energization thereof operates the pawl 99 to step the ratchet wheel 98 a distance of one tooth. Upon deenergization of the magnet |04 a retractile spring |06 returns the armature lever IOI and pawl 99 to their retracted positions as limited by an adjustable stop |01. A spring biased retaining pawl ||0 cooperates with the teeth of the ratchet Wheel 98 to prevent rotation thereof in a reverse direction on the back stroke of the pawl 99 or during rotation of the shaft I6. The number of the teeth on the ratchet wheel 98 and the size of the gear 94 meshing with teeth on the disc 9B, Fig. 1, are such that the sleeve 83 on the shaft |8 with its attached elements is rotated or stepped an amount equal to the distance between. two successive selecting pins 2| in the associated storage units on each operation of the stepping rnagnet |04. The magnet |04 is energized in conjunction with-the transmission of each code group in a manner hereinafter pointed out, and other gears similar to 94 fixed to the shaft 96 engage discs such as 86 associated with the other double storage unit and the single storage unit to rotate associated transmitting equipment one step in conjunction with each energization of the magnet |04. Thus, the transmitting elements of each storage unit rotate in synchronism with one another.

Extending axially from the disc 86, Fig. 3, is a pin |05 uponwhich is pivoted a lever |08. A spring |09 fixed tothe lever |08 tends topivot the same in a Aclockwise direction to bring an insulatively supported vcontact III thereon into engagement with a fixed contacting element II2 insulatively supported on a pin ||3 extending axially from the disc 86. The free end of the lever |08 cooperateslwith the ends of the arms 22 of the selecting pins 2| to hold'the contacting elements and ||2 apart when one of the pins is in its -oper-ated position, as with a pin 2| in its operated position the end of the arm 22 thereof extends beyond the side of the disc |9 and is engageable with the free end of thearm |08. With the end of the lever |08 opposite the end of the arm 22 of a selecting pin 2| in its normal unoperated position the spring |09 is allowed to pivot the lever |08 so as to close the contacting elements VI and ||2. The position of the lever |08 when prevented from pivoting to close the contact elements is shown by the full outline thereof in Fig. 3 and in the dotted outline thereof in the position it assumes when not cooperating with the end `of a selecting pin 2|.

When the sleeve 83 'is stepped the disc 86 is rotated to bring the end of the lever |88 into operative relation with the next selecting pin 2|, and depending upon the position of this particular pin at this time the contacting elements and |I2 will be closed or opened. As the disc steps from one position to the other the end of the lever |08 moves out of operative relation with one selecting pin vand into operative relation with the other. Thus, for each position of the disc 86 the contacting elements |II and I2 asume an opened or closed position in accordance with the position of the selecting pins 2|. A resetting arm ||4 fixed to and rotating with the disc 86 cooperates with the ends of the selecting pins 2| at some point following the lever |08, preferably one or two pins following, to force the selected pins back into their normal unoperated positions Where they are again ready to be operated bythe setting-up arm 29 in accordance with another-,received code impulse when the setting-up arm is opposite thesame. The disc 81 on the sleeve 83 has a lever similar to the lever |08 together with associated con tacting elements, such as ||I and I2, whichare positioned in either closed or opened condition in accordance withthe positions of the pins 2| in the right hand storage unit of Fig. 2. Each of the other storage units also have contacting elements, such as Vand H2, which are positioned in accordance with the operated or nonoperated condition of` the associated selecting pins, and -accordingly the ve sets of contacting elements are positioned in open or closed positions in accordance with the operated or unoperated positions, respectively, of a selecting pin in each of the storage units.

One of the three brushes 9| of a double storage unit, such as the one shown in Fig. 2, is connected through one of the slip rings 88 to bothof the stationary contacting elements, such as I2, While the other two brushes 9| are individually connected to the movable contacting elements and by means of the slip rings 88 andbrushes 9| circuits from the contacts are conducted to a transmitting distributor.

In Fig. 9 the transmitting distributor is indicatedin general by reference numeral ||4 and comprises rings vI I5vto I I8.A A brush I |9 is adapt'- ed to travel from right to left and cooperates with the rings and IIB to bridge the same, while a similar brush |2| rotating therewith bridges the rings and ||8. The ring H6 is connected to a sending line L2, while segments numbered I to 5 of the associated ring ||5 are connected by individual conductors |22 to the tongues |23 of individual relays |24. One side of each of the coils of the relays |24 is connected in parallel by a conductor |26 to battery, while the other sides of the coils are connected by individual conductors |21 to one of the contacting elements of a set such as on the levers |08. Cooperating contacting elements H2 are connected in parallel by a conductor |28 to ground.

The selective operation of the sets of contacting elements and ||2 completes circuits through associated coils of relays |24 whence the same operate to move the associated tongues I 23 in accordance therewith. The relays |24 are neutral, and when energized the tongues |23 move from one stop to the other, and when deenergized the tongues return to their neutral or normal position. 'I'he left and right hand stops associated with the tongues |23 are connected to positive and negative potential, respectively, and in accordance with the operation of the tongues |23 positive and negative potential is applied to the segments of the ring H5. Accordingly, as the brush I9 subsequently and successively contacts the segments numbered to 5 of ring ||5 and bridges the same with the solid ring ||6 a code group of impulses comprising positive and negative impulses is transmitted to the sending line L2. Following the transmission of a code group of impulses the brush |2| bridges the solid ring with a segment |29 of ring ||8 to apply potential over a conductor |3| to the transmitting unit stepping magnet |04. This impulse causes the operation of the magnet |04 to step the ratchet wheel 98 and cause the ends of the levers |08 to move into operative relation the next set of selecting pins 2|. The selecting pins in turn control the contacting elements and |2 in accordance with the position thereof and control the transmission of a representative code group of impulses in the manner described in connection with the preceding revolution of the brushes IIS and |2. Thus, the positions of the selecting pins are transferred to representative impulses and distributed to a sending line L2.

Provision may be made in any one of a number of well-known ways to prevent the levers |08 from approaching too close to the setting up arms 2S, such as by opening the circuit to the stepping magnet |04 when the number of pins between the setting up arms 29 and thev levers |08 decreases to less than a predeterminedl number.

It is obvious, of course, that various modifications of the invention may be made Without departing from the spirit or essential attributes thereof, and it is desired, therefore, that only such limitations be placed thereon as are imposed by the prior art or are specicall'y set forth in the appended claims.
