To all whom t't may concern:
Be it lmown that l, Amos F. DIXON, a citizen of the United States, residing at Newark, in the county of Essex and State have invented a certain new and useful Improvement in Controlling Systems, of which the following is a full, clear, concise, and exact description.
This invention relates to controlling sys toms of the type wherein the actuation of one mechanism is automatically governed by the persistence of operation of another independent mechanism, and its principal description and claims,
object is to provide a system of this type which performs its function independently of the condition of any material upon which the mechanisms are operating.
To this end a system is provided wherein one operating mechanism controls the movement of a mess er or series of members and a second operating; mechanism controls the movement of a second member or series of members, the members or series of members coiiperat ng to regulate the operation of the second. mechanism The above and oth tion will be fully set er objects of the invenrth in the following and will be more readily understood by reference to the ac.- companyin'g drawing in which the invention is shown diagrammatically. a The inventionis shown arraned to conthe tape ma mission of signals. It

has been imparted to illustrated embodiment of action or cireuit devices the'operating mocha The perforator 5, among other things,
comprises an electromagnet 6, a contact maker 7 and a tape feeding device. No detailed illustration or description of the perforator is necessary since any of the well be used. the couact maker 7 is closed by the depression of each punch selecting key to complete a circuit for a source of energy 8, through the coil of magnet 6. The energization of magnet 6 not only forces the selected punches through a blank paper tape 10, but the attraction of its armature 11 causes the actuation ot a pawllfl and a toothed wheel 13 by mes-iris of which the tape is advanced Step-by-Step to present an unperforated surface. to the punches. Joined in parallel with the coil of magnet 6 by conductor 15 is an electromagnet 16, Electromagnets 16 is provided with a movable armature 17 pivotally, carrying an actuating pawl 18. The pawl 18 on its forward stroke engages the teeth of a ratchet 19 which is rotated thereby in the direction ofthe arrow. In rotating, the
carries with it a wheel" 20 provided with a single gear tooth 21. Riding upon a shaft is a wheel 26 provided with teeth on its circumference which are adapged to be engaged by the tooth 21 of wh 20. Ratchet 19 is provided with ten tee h and it will be readily understood that upon each closing of contact maker 7 the ratchet 19 and wheel 20 will move one steq, nd that of the teeth of wheel 26 which is vthereby the direction of the arrow, This ratio of movement between ratchet 19 and wheel 26 may be altered to suit any conditions without departing from the spirit of this invention.
Ihe tape 10 passes directly from the perthe transmitter 30 which'may be constructed like any one of several well known types. It is rovided with an actuating magnet operat ng with'the tape, in controlling the p (not shown), pro- },sten-by-step drawing or feed-- ge one I 31 which, in addition to coing of the tape. This is accomplished by means of anarmature 32, pawl 33 and feed wheel 34.
The coils of magnet 31 are connected to ground and by a conductor 40 to a magnet 41. This magnet is similar in all respects to magnet 16, and through the agency of its armature 42 and pawl 43 causes the stepby-stei rotation of a ratchet 44, likewise provided with ten teeth. Ratchet 44 carries with it a wheel 45 which like wheel 20 has only one tooth 46. This tooth is adapted to engage the teeth on the circumference of a. wheel 50, which also rides on shaft 25, so that for every ten steps of ratchet 45, wheel is rotated one step in the direction of the arrow.
A bracket 51 secured to wheel 50 carries a pair of contact springs 52 and 53 which are connected to slip rings 55 and 56 respectively. A pair of brushes 57 and 58 bear upon the slip rings 55 and 56 respectively so that the rotating springs 52 and 53 may be connected in a circuit to be presently described.
The circuit for magnet 41 is continued to a point where it divides and passes in parallel through the windings 66 and 67 of a relay 68. The windings 66 and 67 are arranged difi'erentially so that when current is passing through both, an armature 7 0 will not be attracted, but when current is passing through only one. winding, the armature will be drawn up. Armature 70 is connected to a source of energy 71 and is normally out of engagement with a movable contact 72 but is adapted to make contact therewith under conditions to be hereinaftcrdcscribed. Movable contact 72 normally engages a fixed contact 73 but is arranged to be se arated therefrom when engaged and moye by armature 70. One terminal of Winding 66 1s joined to brush 57 by a conductor 89 and one terminal of winding 67 45 is joined to the movable contact 72 by a.
. spring 53.
The wheel 26 is provided with a pin 190 projecting into the path of and adapted under certain conditions to be engaged by spring 52 and thus separate this spring from This condition obtains when wheel 26 ceases to rotate or rotates less rapidlv than wheel 50.
meters winding 66, magnet 41, conductor 40 and the coils of magnet 31. It will be observed that current is now flowing through both windings of relay 68, which thereupon becomes deenergized and its armature 70 is released. Hereafter as long as the springs 52 and 53 are together, the impulses from i the source of energy .9.5,.governed by distributer arm 92, will efiect the advance of the tape 10 andthe wheel 50. It is apparent that, since the stopping and starting of the transmitter occurs during the interval between thejtimes of imparting the selecting impulses, there will be no tendency to transmit false combilllations of signals. lhe minimum amount of slack tape between the pertorator and transmitter may be varied to suit any conditions and when this minimum is reached, the transmitter will automaticallycease, to be automatically started again when a surplus of tape, above this amount, is provided.
What is claimed is:
'l. A controlling system for printing telegraphs comprising a tape perforator, a tape controlled transmitter, and separate inde pendent mechanisms actuated by said pertorator and said transmitter independentiy of the tape co'ciperating to stop the action of said transmitter when said perforator stops or its action is tardy.
2. In a controlling system, the combination of a machine, a movable member controlled thereby, a second machine, a second movable member controlled by said second machine, and switch elements carried by one of said members and controlled by the other said member, said switch elements being adapted. when disengaged to effect a retardation of the movement of said second ma chine, for allowing variations in the speed of said machinesin only one direction under operated tuated by said machines, contact spring members carried by one of said mechanisms, r
means provided by the other of said mechanisms for causing the engagement and disengagement of said spring members, and means controlled by said spring members when disengaged for retarding the movement of one of said machines whereby the amount of operation of one of said machines may be unlimited and the amount of operation of the other of said machines may not exceed the amount of operation of the said first mentioned machine.
4:. A. controlling system comprising two independently operable machines, the rotation of one of which is to be controlled, separate independent rotating mechanisms actuated by said machines and adapted to rotate in the same direction, normally closed contact members carried by the mechanism by the controlled machine, and contact disengaging means located on the other of said mechanisms in the path and ahead of said contacts in the direction of rotation, said disengaging means being adapted to open said contacts when the former mechanism rotates faster than the latter mechanism, and means controlled by said contacts to retard the operation of the controlled machine during the disengagement of the contacts.
