ELECTRICAL SYNCHRONOUS MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 256,275, dated October 9, 1883.

Application filed April 12, 1883. (No model.)

lilo 0]] 1071,0172 it may concern:

Be it known that I, Parnick B. DELANY, of the city, county, and State of NcwYork, have invented certain new and useful Improve inents in Electrical Synchronous Movements, of which the following is a specification.

The object of my invention is to insure the exact, equal, and like movements of apparatus widely removed and connected by an elec tric circuit. Such apparatus is capable of various applications in the field of telegraphy and elsewhere where the successful operation of a system, whatever it be, is dependent up on the synchronous movement of apparatus at different stations.

My invention is applicable to the various purposes for which said movements may be It consists in an improved organization by which the parts are brought into synchronous movement and are maintained so by elcctrical impulses transmitted over the line either of retardation or acceleration, according as the apparatus at one station tends to move faster or slower than the apparatus at the other stat-ion.

' 111 other applications for Letters Patent filed of even date herewith, and serially numbered MASQ, 91,491, I have shown other ways of controlling the movement of substantially similar apparatus from one station, as well as reciprocally from two stations. Such applications, however, cover organizations different from that herein set forth, and the claims in this are confined to the peculiarity of structure and operation herein described.

The accompanying drawing is a diagrammatic stations, X and Y, connected by a main line.

In an application for patent filed of even date herewith for improvements in telegraphy, serially numbered 91,498, I have shown and described an organization of apparatusin which vibrating forks actuated by local viand toothed armaturedisks substantially like those herein shown are employed. In the present case, as in the case referred to, the

rotary armature-disk E, actuated by the motor-magnets, is fast on and imparts motion to l the vertical shaft E, which is connected with the main line and carries the trailing finger or circuitcompleter j, which travels over the series of contacts arranged on a stationary circular table, G, of insulated contacts, placed concentrically around said shaft.

The present invention involves certain dif ferences in the arrangement and connection of the contacts devoted to the correction of the movements and the maintenance of their synchronous action, and also in a different an rangement of correcting-magnets for that pur pose.

I have shown and prefer to employ vibrating forks tuned as nearly as possible to the same pitch, so as to possess the same normal rates of vibration. It is not necessary, however, that tuned forks should be used, or that forks at all should be used, as a vibrator of any description, actuated either by the action of electromagnets or by electrically-controlled apparatus, may be employed, as fully set forth in the application No. MASS above referred to.

In the accompanying drawing I have shown at each station a vibrating fork, A, mounted at its base in a suitably-insulated support. The tines of the forks are automatically-kept in vibration, when once started, by a local circuit, (indicated by small dotted lines,) in which the vibrator-magnet a a is placed. The poles of this magnet are arranged upon the outsides of the tines of the forks, and are provided with suitable screw pole extensionpieces, a, which may be approached to or withdrawn from the tines of the fork, in order to regulate their influence thereon and the consequent rate of vibration of the fork. On the inside of the forks, prefer. bly near their ends, are placed platinum contactpieces b I), which make and break contact at each vibra tion with very delicate platinum contact springs or fingers c c, which project from pivoted insulated arms or levers B B, the positions of which levers are regulated by thumbscrews b against which they are normally drawn by coil-springs.

The local circuit which vibrates the tines of the fork is made and broken between the platinum contacts Zip, as is well understood, and the ICO placed around these points.

. breaks contact between the platinum contacts b c, and thereby makes and breaks the mo tor-circuit, indicated by the broken lines. These contacts are also shunted by arheostat, Rh, to prevent sparks. The makes and breaks in the motor-circuit magnetize and demagnetize the coils of the magnet D D, and the alternate attractions and cessations of attraction upon the armature-teeth e of the rotating armaturedisk E cause that disk to rotate continuously. and evenly, and carry round the trailing finger or circuit completer f, which is carried by the vertical shaft E, and moves over the insulated contacts on the table of contacts G. The forks at the two stations are, as above remarked, as nearly as possible of the same pitch, so that the normal rate of vibration will be about the same; but by adjusting the screw pole-pieces a to or from the tines of the fork, the speed of vibration may be so accurately adjusted that the two forks may be brought to vibrate at a )proximately the same speed. Each fork is vibrated by its own independent local circuit. It is impossible, however, to so accurately adjust the pole-pieces relatively to the tines of the forks as to insure their synchronous vibration. The

slightest ariation, however small, if continu'-' ous, will, as is obvious, ultimately carry one of the rotating apparatus so far ahead of the other as to destroy their proper relative movement. 7

The above description of the transmission apparatus E E']" G will be suflicient to enable any one skilled in such matters to construct an instrument fulfilling the necessary condi tions, The apparatus is, however, fully illustrated and described in detail in-the applica tion N 0. 91,493, for improvements in telegraphy, above referred to.

()n the stationary tables of contacts I have shown sixty insulated contact-pieces; but of course the operationis not dependent upon any exact number. These contacts are numbered in six separate series, froml to 10. The .9s and 10s on each of the tables are thrown out or unconnected, and are devoted to maintaining the synchronous movement of the apparatus, as is hereinafter described. The other eight contacts in each series may be devoted to the transmission of impulses of electricity for any purpose for which they ,may be desired. as will now be described. In the drawing I have shown the 1 s and 5s of each series electrically connected together, the 2s and the 6s similarly connected, the 3s and the 7s, and the 43s and the 8s, and these independently connected series may be connected with independent apparatus for any suitable purpose at each station. It will be obvious that, if the trailing fingers f at each station move together so accurately that they will be on correspondingly-numbered contacts at the same time, an electric circuit will be completed through the contact at one station, the trailing finger f, radial arm f, vertically-rotating shaft E, main line to the opposite station, and through the trailing finger f to the correspondingly-numbered contact. If these contacts are therefore connected up with telegraphic or other apparatus in circuit with a battery, of course an electrical impulse will pass over the line through these two contacts once in each revolution of the trailing finger that is, at that point in the revolution when the two trailing fingers f at bothstationsare on the contacts.

As above mentioned, the contacts 011 the stationary table, with the exception of the 9s and lOs, are connected in fourindependent series, two contacts in each of the six sets of contacts being given to each of the four independent series. The instruments or apparatus therefore, which may be connected with the independent series of connected contacts, will each receive twelve impulses of electricity for each revolution of the trailing fingers. If, there fore, the forks vibrate at the rate of eighty-five per second, and make and break the motorcircuit that number of times per second, and there are thirty teeth in the rotating armaturedisk, that disk will be rotated nearly three times per second, and the line will therefore be given to each of the four independent series of connected contacts thirty-four times per second. The circuit and current will be therefore, for practical purposes, constant and entirely independent for each pair of correspond 1 ing instruments. At station Xthe 10 contacts are thrown out and not connected with any circuit or contacts. The 9s are, however, all electrically connected to each other, as will be plain upon an inspection of the drawing, and to the correcting-battery O B. The 9s at station Y are thrown out or unconnected, with the exception of one of them, which is made use of i for a particular purpose, presently described, while the 10s are electrically connected to each other and to a wire, I, which passes through the coils on the poles of deterring-magnet L L, which are placed outside the tines of the fork. and from thence to ground. The single 9 above "referred to is connected to a wire, m, which passes to ground through the coil of a sounder, S. At this point in the table an extra contact, 8%, is introduced, and the adjoining 9- that one connected to the sounderis reduced in width. The reduced 9 and the small extra contact together only occupy the space that would be occupied by a full-width 9, so that the relative 'arrangenientof contacts and separating-spaces is maintained. This extra contact 8% is connected by a line, a, through the coil of a magnet, N, interposed between the tines of the fork, andthenee to ground. It will be further noticed that the 10s, which are all connected together and to the line I, are built out or extendedtoward the adjoining 9s. The outer magnet, L, which is connected to the lOs, is the deterring or retarding magnet, and as there are six 10s in the circle of contacts, it is possible for six retarding impulses to be received over the line, as will be described, for each revolution of the trailing finger f. The magnet N, interposed between the tines of the fork, is connected with the single extra contact 81 interposed between the 8 and the reduced 2). This magnet is the accelerating-magnet, and it will be possible for one impulse of electricity to pass through its coil for each revolntion of the trailing fingerf. Assuming that both of the trailing fingers are moving synchronously, it will be obvious that when the fingers at stations X and Y rest upon the 9 contacts no current of electricity can be on the line, except when the finger at Y is onthe reduced 9, which is connected with the sounder S. Then the sounder, which is preferably muffled to reduce the sound, will tick once in each revolution of the finger f, and the operator will know that the apparatus is running properly. If, however, while the finger at station X is on a 9, which is connected with the correcting-battery G B, the finger at station Y should move a trifle faster, so as to strike the side of the extended 10 at that station before the tongue at station X had left the 9, an impulse of electricity would be received from the battery 0 B through the 9, trailing finger, line, trailing finger at station Y, contact 10, and line Z, to the deterring-magnet Lfand the effect would be to retard the vibration of the fork at the station Y. 1f the finger at station Y should tend to run a trifle slower than that at station X, it would touch the small extra contact 8% while the finger at station X is still on a 9. An impulse of electricity would therefore pass through the coil of the accelerating-magnet N and accelerate the vibration of the fork and the consequent rotation of the trailing finger at station Y. \Vhen the trailing fingers are therefore once brought into synchronous movement,the finger at station Y will be locked, as it were, between the extra contact and the ltl s, so that any acceleration in speed will be promptly met by a corresponding automatic retardation, and any retardation by a corresponding automatic acceleration.

In practice the apparatus is so adjusted that the rotating armature-disk at station Y tends to move slightly faster than that at station X. This tendency is overcome by the six retarding-contacts. As the tendency at'station Y is toward acceleration, but one acceleratingcontact is deemed sutli cient. This contact may be brought into service where too great an impulse of retardation has been imparted to the apparatus, .or where from any cause the normal accelerating tendency of the armature disk is momentarily disturbed.

I11 starting the rotating armature-disks at both stations, impulses of rotation are im-- parted to them by means of thumbscrews upon the ends of their vertical shafts, or otherwise, until the speed of rotation coincides with the magnetizing and demagnetizing of the motor-magnets, when the wheels will be picked up by the magnets and continuously rotated, as will be well understood. The speed of vibration of the forks can then be regulated by the adjustable pole-pieces 011 the vibrator-mag net. In practice the apparatus at station X is started independently of any special adjustment, the adjustment being made at station Y, so as to have the apparatus there run a trifle faster than at station X, as above mentioned.

In connecting up the apparatus the switches I? Q are opened and the fork started into vibration at station Y, the apparatus at station X having previously been started. If the trailing fingers happen to start in synchro nism, the sounder S will tick, and ifthe ticking continues for a short time the operator will adjust the pole-pieces of the vibratoi magnet very slightly away from the tine of the fork,

so as to tend to increase its rate of vibration.

Then, if the sound begins to go away on the sounder S, he closes the switches I and O, and the apparatus is in working condition. If the apparatus does not start in synchronism, there will be no sound at first on the sounder S; but the operator at station Y, by screwing the pole pieces away from the tines ot the fork, will cause them to vibrate at a speed which, by previous understanding, he will know to be very much greater than that of the fork at the distant station. The finger at Y will therefore gain rapidly on the finger at X, and as they occasionally come into conjunction, there will be a stroke on the sounder. Then, by gradually adjusting the pole-pieces to app roach them to the tines of the fork, the strokes on the sounder will become less frequent, and by continuing the adjustment the fingers will travel together sufficiently long to give a se ries of ticks on the sounder, and when the ticking on the sounder continues for several seconds or more the switches I? and Q. are closed and the apparatus is in proper condi tion, any subsequent variation being automatically corrected, as above described.

I have said that the magnets L (the poles of which are on the outside of the tines of the fork) at station Y are retardirig-magnets, and that the interposed magnet N is an accelerating-maguet. This Ihave demonstrated byrepeated experiments and practical use, and the operation may be thus explained: The poles of the vibrator-magnet are placed on the outside of the tines, so that the tines vibrate in magnetic fields which modify or in a measure overcome the normal speed of vibration. As this magnetic field is decreased in strength the tines vibrate more freely, and consequently more rapidly. \Vhcn, however, these exterior magnetic fields are increased or supplemented by the action of the deterring-magnet L IJ, the resistance to the vibration of the fork IlO to the vibration of the forks and the sum of the exterior attraction on the tines of the fork, and permitting afreer, and consequently more accelerated, rate of vibration. If, for any reason, fewer retarding impulses are desired, some of the 10s at Y or 9s at X, or someat each station, may be thrown out or left unconnected, and if more accelerating impulses are needed, obviously additional 8-} contacts may be added. Obviously the greater number of correcting contacts might be connected to the acceleratingmagnet and the lesser number to the deterring-magnet. Vhen thus arranged, I would prefer to connect the connected 10s to the accelerating-magnet and the 8% to the deterring-magnet. In this case the apparatus at Y would of course be adjusted to run slower than that at X. Other variations will doubtless be suggested to skilled persons.
