The

acts \1 2 v e corla thereof. up a? the'sle pun file side iii? of the frame 5 and. has mounted between its members a ratchet wheels 43 and 44, in position to be engaged by the pawls l3 and 17 hereinafter designated as the stepping and holding pawls respectively. The ratchet wheel 43 is carried by a sleeve 45 secured to the shaft 42, and there is supported upon the same sleeve as the ratchet wheel 43, a contact carrying device 46 consisting of a segment of a "disk and having mounted on one face and near the periphery thereof, projections or pins 47, 48, 49 and 50. Secured to the outer end of the shaft 42 is a coil spring 53 adapted to return said shaft to its normal position. A protecting cover 54 is provided with means for securing it to the frame member 41 in position to cover the spring 53. The contact point 56 carried by the contact device 46 is arranged so that the rotation of the ratchet wheel 43 through a given are will bring said contact point 56 into ongagement with a contact spring 57 carried by the ,frame 18. As shown more clearly in Figs. 2 and 3 the springpressed pawl 20 is pivotally mounted upon the outer face of the frame member 41 and has a concave portion 60 projecting through an opening in said frame member 41 into position where it may be brought into engagement with the pins 47 48, 49 and 50 of the contact device 46. The ratchet wheel 44 is loosely mounted upon the shaft 42 and carries a contact spring in position to engage a contact spring 66 mounted adjacent to the contact spring 57 but insulated therefrom. The hub of the ratchet wheel 44 carries a weight 67 for the purpose of returnin' said ratchet wheel to normal position. 0th of the ratchet wheels 43 and 44 are provided with concentrically arranged slots 70 and 71 through which project a pin 72 secured at one end of the frame member 40 for the purpose of limiting the movement of said wheels 43 and 44. An adjusting screw 75 carried in a projection 76 of the frame member 40 engages the stepping pawl 18 to control its engagement with the ratchet wheels. The closure of the contacts 56 and 57 completes circuit for a signaling device 80 as shown on Fig. 4 of the drawing, while the closure of the contacts 65'and 66 closes a short circuit of the stepping magnet 6, thus preventing the operation of the selecting device after these latter contacts are closed.

Referring now to the o oration of the device, it will be assumed t at the particular combination to which thesclector responds after closing the signaling contacts,

rotatable shaft 42 carrying duri which time the circuit is open meccede by two short impulses and a fourth pause during which time the circuit is succeeded by three more impulses. e holding and stepping magnets being connected in series, the first impulse through these magnets will pull up both armatures, the operation of the armature 9 releasin the stepping and holding pawls 13 and 1 v, and the operation of the armature 8 carrying the stepping pawl into on agement with acting magnet, the space between succeeding impulses will be insulficient to permit it to drop back, so that the retaining paw 17 will be constantly in engagement with ratchet wheels 43 and 44 except when Jzhe circuit is open for a suflicient length of time to rmit said armature 9 to return to norma position. This being the case, the two succeedin impulses will advance the ratchet w eels two steps farther and if the circuit is o n at this time for a sufiicient len h of time to permit the release of the hol in magnet armature, the concave portion arm 0 will move into enga ment wi the first projection or pin 47 o the contact device 46, thus. holding this contact device and with it the ratchet wheel 43 in the position to which it is advanced by the first series of impulses. The holding pawl 17, however, is withdrawn from engagement with the ratchet wheels 43 and 44 and the ratchet wheel 44'will return to normal position by reason of the weight 67. In a like manner the next four impulses of the combination will advance the ratchet wheel 43 and contact device 46 to position whereby the release of the holding magnet will bring the pawl 20 into engagement with the projection or pin 48, again permitting the ratchet wheel 44 to return to its normal position. This operation will be continued until the pawl 20 has successively engaged, each of the pins or projections 47, 48, 49 and 50 of the contact device 46 whereupon the succeeding impulses will move the contact point 56 into engagement with the contact spring 57 thus completing the circuit for tie signal 80. It will be noted that the pawl 20 when in either of its extreme positions is out of the path of movement of the projections or pins 47, 48, 49 and 50, thus permittin the ratchet wheel 43 to return to norma position when the circuit the pawl 20 being released'b theicence.

opening occurs at any except the one determined the positions of the pins in the contact device l6. If now, however, a succession of quiclcinipulses continued for a :1 number of times he sent over the line and through the selector magnets, these impulses Will to step both the ratchet wheels 3 and l-laround, until the contacts 85 and 6? controlled by the ratchet wheel iiare closed.

net of the selector is short, circuitcd and will not obtain sul'licient current to operate, thus ellectually preventing the closing of thesignaling contacts by means of a suc- CBSSIOD'Of rapidly occurring impulses. This trated in connection with an ordinary toleby-step circuit clos .ing to return said circuit closing device tograph line it will be noted that the electroinagnets 6 and 7 are connected in series with a sounder 86 and a local battery 87 adapted to he closed through the front contact of an ordinary Morse relay 91 in series with the line Telegraph keys 88, 88 are also connected in the line 85 for operating the Morse relay 91. At each of the stations at which is located a selector, there are provided impulse transmitting devices 90 for sending the necessary combination of current impulses for closing the contacts 56 and 57 of the selector and operating the sig 112.1 80.
