Definitions

  • the objects of theinvention are to provide novel methods of' starting and stopping motors by means controlled through the receiving selectors at each station to provide a motor control operable under the control of the selector mechanism, or under the combined'control of the printer shift mechanism and the selector mechanism; to provide a 40 control operable to stop themotors at each station in response, to selective combinations sent out from .any station and to start the same in response to the commencementof transmission or in response to the transmisal; to provide a main and an auxiliary ca 1 system, and such other objects as will appear hereinafter in the detailed description of of the invention, of which- Figure 1 is afragmental plan view parpreferred embodiments signal, and to be released tially in diagram of,the mechanism applied to a single magnet selector.
  • Figure 2 is a fragmental front View of the mechanism sLown in Figure 15;
  • Figure 3 is a fragmental plan view show-' ingihe mechanism in actuated condition.
  • the parts of the selector and printer with which the parts of the present invention coact have been given the same reference characters as in the c'opending case.
  • the selector magnet 8 is preferably normally energized when no selections, are being made.
  • Each signal combination comprises a selec-' tor start condition, a code combination of selecting conditions and a selector stop con dition Magnet 8 is deenergized in response '15 to a start condition and this permits endwise movement of cam shaft 15. Due to this endwise movement, shaft 15 starts into rotation and thereafter the code combinations are received and energize 8 in accordance with the received combinations to selectively position fingers 37 to 41.
  • the cam shaft then trips a mechanism to permit notched selector bars 59 to 63 to assume positions in accordance with the selectively positioned fingers 37 to 41, and at the same time to set into operation the printing bail which will cause movementof the selectedactuating bar 108 into the aligned selector bar slots to cause an operating movement of the selected bar. While the selection set up on bars 59 to 63 is being carried out-,restoration of fingers 37 to 4:1 and-the resetting thereof 1n accordance with asucceeding selectivecombination may proceed.
  • Carriage shift mechanism including arms 246, shaft 247 and shaft arm 265 are arranged to be operated and locked in shifted condition, by an actu-- 'ating bar. 108 in response to a special shift I by an unshift bar ram 108 by a special unshift signal, all as described in the copending case.
  • a support 300 Se cured to base plate 1 is a support 300 in which a spindle 301 is rotatably supported.
  • Spindle 301 has formed integrally therewith a bearing collar 302 and rigidly se cured thereto is an actuating arm 303.
  • a spring 304 secured to arm 303 and to support 300 normally forces the arm 303 against the selector support as shown in Fig. 1, with the end thereof directlyin the path of actuating movement of one of the bars 108.
  • Rigidly secured to the lower end of spindle 301 is an arm 305 to the outer end of which a member 306 is pivotally secured at 307, in a manner to be supported thereby.
  • Member 306 extends across the front of the selector and is guided for movement b a pin or screw 308 which extends througli a slot 309.
  • a latch extension 310 is formed on the end of member 306, and a notch 311 is cut therein to permit the free movement of resilient latch member 312 rigidly secured to armature 9 by means of screws 313 so as not to interfere with the operation ofthe armature.
  • At the other end 306 is bent at right angles and an adjustable contact operating screw 314 is screwed therein and secured by means of a lock nut 316.
  • a spring contact member 317 is provided carrying contact 318 and an operating block 319 arranged in the path of movementof 315. Contact 318 is arranged to normally engage a contact 320 secured on a member 321.
  • Members 317 and 321 are insulated from each other and from the mechanism by means of insulating members 322, and are secured to support 300 by screws 323. Suitably secured to the printer and properly insulated from each other are contact members 324 and 325, carrying contacts 326 and 327. A block.328 is secured to 327 and arranged in the path of arm 265 so that when the printer mechanism is locked in shifted position contacts 326 and 327 will be opened by member 265.
  • the printer motor 329 has the supply circuit connected in series by means of conductors 330, and 331 through contacts 318 and 320, and contacts 326 and 327 are connected by means of conductors 332 and 333 in shunt with respect to the circuit through contacts 320 and 318. When either set of contacts is closed the motor will run,
  • An auxiliary signal lamp 334 is' connect- A ed by conductor 335 to the negative pole of the electrical supply and to contact spring tatin Operation.
  • the end of arm 303 is disposed in front of an actuating bar 108 which may be the blank signal bell operating bar or a .special motor stop bar.
  • actuating bar 108 which may be the blank signal bell operating bar or a .special motor stop bar.
  • a'signal is sent to actuate the special bar 108.
  • the combination is received on the selector mechanism and bars 59 to 63 are set in accordance therewith.
  • the printing mechanism then operates to permit the special bar 108 to drop into the aligned slots and when in the slots the end of this bar will be lowvered and as the bail moves forward, the
  • the shift controlled contacts 326 and 327 may be added in shunt to the contacts 318 and 320 in such position that they are held open by the printer mechanism in the upper case or figures position and are closed when the printer mechanism is in the lower or letters case.
  • the letters signal following the bell signals releases member 306, permits contacts 338 and 339 to open and extinguishes the lam
  • the flash of the-lamp and ringing of the bell indicate the circuit and the nature of the message being received. If immediate attention is desired the bell signals are not followed by anotlfer signal and accordingly the contacts 338 and 339 will be locked in closed position and lamp 334 will remain lighted at the end of the signal and until the required attention is given. ing of the lamp followed by a prolonged lighting thereof indicates the circuit and matters requiring immediate attention, while the flashing of the lamp only, indicates the circuit, and that immediate attention is not re uired.
  • he stop mechanisms may obviously be applied for open circuit working with magnet 8 normally de-energized by reversing the position of member 310 so that contacts 318 and 320 will be locked'open with the magnet 8 de-energized and so that these contacts will be released and permitted to close when the magnet is energized. Otherwise the operations will be the same as above described.
