SPECIFICATION forming part of Letters Patent No. 447,045, dated February 24, 1891.

Application filed May 9, 1890.

To all wwm zit' may concern:

Be it known that I, NOEL B. GINOOHIO, a citizen of the United States, residing at New York, in the county and State of New York,

` have invented certain new and useful Improvements in l\Iagneto-Electric-Signal Devices, of which the following is a specification.

My invention relatesto magneto-electric Signal devices, and more especially to that class adapted to be used in connection with telephone and telegraph and other signaltransmitting lines, and it has for its Object to provide an improved device whereby certain prearranged and distinctive signals can be given at will; and to these ends my invention consists in the construction, arrangement, and combination of the various devices, substantially as hereinafter more fully speci- Referring to the accompanyin g drawings, wherein I have illustrated one and the preferred embodiment of my invention, Figure 1 is a plan view of the box, showing the door 5 box. Fig. 3 is a diagrammatie representation showing` the Connections, and Fig. 4 is a diagram of the wheels.

The box A may be of anysuitable or desirable construction, and is preferably provided with a door B, connected to one side of the box by hinges, which form a medium of Connecting the circuits between the switch O, located on the cover, and the apparatus located within the box. Secured in the box is a magneto-generator D, which nay be of any snitable and preferred construction, although I have shown it as consisting of a number of curved permanent magnets d d, 0 connected by steps to pole-pieces d' d', be-

tween which rotates the arnature mounted on the shafi; E, as more particularly set forth in my application, Serial No.*339,l19, filed February 4, 1890, and bearing on the end coils of the armatureis aplate or brush e, supported on the frame of the nagnet, but insulated therefrom.

Supported in suitable bearings between the limbs of the magneias by brass or other non magnetic plates D is a shaft F, carrying open. Fig. 2 isa longitudinal section of the Serial Not 351,178. (No model.)

a gear-wheel f, gearing with the pinion e' upon the shaft E, and also mounted on the shaft F is a pinion f', meshing with the gear f mounted. ona stud or bearing secu red to' one of the plates D', and having agear f engaging the pinion f* on the cirouit-breaker shaft.

It is often desirable in devices of this kind to be enabled to send apredetermined Signal nade up of a certain number of smaller signals or impulses, so that any particular subscriber or other person may be called by simply rotating the arnature, the circuits being properly arranged beforehand. In order that this may be done with accuracy and 6 5 that the timing of the elements of the signals nay be regular with respect to one another, I provide a number of circuit-breakers, which are mounted upon the circuit-breaking shaft G, 'and are rotated through the 7o V' mechanism just described whenever the shaft is turned and a current generated. These circuit-breaking-wheels may be of any desired construction; but I have shown them as consisting of disks having notches cut in their periphery or projections extending therefrom, so that as they rotate they will present a greater or less surface to a brush or other Connecting device, and the circuit will be closed -to a greater or less extent and a given number of times and in certain relations at each rotation of the disks. These disks are represented at I'I, and are numbered in the present instance 1, 2,' 3, and 4, it being understood, of course, that there'may be a greater or less number of circu it-breakers, all mounted on the same shaft, according to the uses to which the apparatus is to be appliedj A number of brushes H' are mounted on a suitable support, and their free ends are held go adjacent to the circuit breakers' and are adapted to make contact therewith as they rotate on the shaft.

It is desirable that the circuit-breaking shafi; shall make one complete rotation in order that a complete Signal may be sent, and should then be stopped, so that the operator will know when he has completed the Signal.

'In order to do this I provide a suitable stopping device which shall control the rotation Ioo of the shafi: F and be in turn controlled by the rotation of the circuit-breaking shafi'. While different means may be used for carrying this out, I have shown the shaft F as provided with a block or disk I, having two notches' on opposite sides. The shaft G is also provided with a disk J, having a single noteh j in its periphery. Pivoted to the frame-work in some suitable position is an arm K, carrying a projection or stop ?ignormally engaging one of the notches 'of the disk I, a spring L norinally holding it inthis lockedposition. The arn K is provided with an extension k carrying a disk or wheel M, which is adapted to fit into the slot j in the periphery of the disk J, and a spring m s-urrounds the eXte-nsion of the arn K a-nd presses the disk M outward against the stop on'.

In Fig. 2 the nachine is shown in its stationary position, and before the shaft can be otated it is evident that some means must be provided for unlocking the d-evice, and I have shown such means as consisting of a bush-button LT, projecting through the side br the box and operating a bell-.crank lever n, which impinges on the end of the rod, forcing the Wheel M out of the notch in the disk J, and thereby also releasing the projection l from the noteh tin the disk I. The shaft F can then be rotated, operating the armature to produce the alternative cu rrents,which are controlled by the circuits and switch hereinafter described, so that the particular signal may be sent over the line. When the circuit-breakers have completed one rot-ation, the Wheel M falls into the noteh j of the Wheel 1 J, and the projection 7,; is thereby thrown into engagenent with -one of the notches z' of the disk I,.and the apparatus is locked against further rotation. the purpose .of allowing the dish or wheel M to yield slightly and to act somewhat as a break to prevent too quick or sudden stopy page 'of the parts, which might injure or 0thi erwise disarrange them.

In order to prevent the shaft F being rotated backw-ard, and thereby sending the signal in the reverse order from what was intended, I apply a ratchet-wheel O on the shaft F, into which the pawl 0 eugages, allowing free rotation in one direction,but preventing rotation in the opposite direction. Suitably nioun'ted in the box is a polarized magnet P, operating the arnature p, carrying the bellhanmer p', operating the. bells in the usual way. The crank Q for drivi-ng the shaft is preferably provided with a sleeve Q', having a groove g engaging a pin g' on the shaft, -and a spring (1 tends to naintain the sleeve in its outermost position, and when the erank is.

closed cireuit, and then `the shaft w-ill be 1 0-- .tated,and=when the crank Q is released -i-t' will normally return toitsouter position, as shown. Monnted on the cover of the box I have shown I provide the spring m for a switch C, consisting of a switch-atm C',

conneeted to a thumb-nut C and having an index-arm 0 passing over a plate or other indicator C The arm C' is preferably of spring material, having a slight projection on its end, which may be beveled to fit the cups or other con tact-pieces c c' 0 0 0 These pieces are conneeted electrically witl the different circuit-breakers and with the frame of the machine, the conductors 1, 2, 3, and 4 being connected to the brushes of the respective circuit-breaking wheels, and the conductor 5 being connected to the frame of the nachine. The switch-arm is connected by a conduetor G to the binding-post 7, which may lead to the ground, if desired. The bindingpost 8 is eonneeted .to .the 'lineire 9, and thence by a conductor 10 to the eoils of the bell-magnet, from which -a conductor llleads to the conductor 12, and thence to the brush .e on the end of the armature-shaft. From the binding-post 7 a eo nduetor 13 leads to a spring 14, normally bearing on `the sleeve Q', and another spring 15 bears upon the opposite sideand is connected to, the conductor 1-2. Th'us the norinal eircuit when the machine is -at rest is such that a signal from a distant station may operate the bell P, passing through the binding-post S, eonductor 10, bell-magnet conductors ll and 12, through the Springs 14 15, eo nduetor 13, and bindingpost 7 to ground. VV-hen, however, the generator is operated, the circuit between the Springs li and 15 is broken, as before described, and it will then be traced from ground through the binding-post '7, conductor 6, to the switch-arn C', to one of the contactpoints, as 6 thence by the eonductor 1 to the brush, over the corresponding circuit-breakin g w-heel to-the shaft of the same, and through the coils of the .armature oi-it through the brush e, through the eonduetors 11 and 1.2, eoiis ofthe magnets, eonductor 10, bindingpost 8, and line 9.

It will be understood that the e-ireuit as last traced will be broken or closed in accordance with the construction and arrangement of the circuit-l' reakerWheel included therein. These wheels are shown in one .arrangem-ent in Fig. 4. \Vhile many arrangements can be made, I have found it especially advantageous, when it is desired to call one of a .number of SlIbSCYbGPg fOP instance,upon the same line, to cause a preliminary Signal to be given, and When the uiachine is so adapted I provide each eircuit-breaker with a projection X, which will cause a s-ignal ofthe desired length to be given and will warn the hearer that a call is to be sent. This is then followed with the desired number of projections Y, arranged in proper groups a proper distance apart to insure the signal given.

It will be seen from inspection that ,the disk X, Fig. 4, will first 'send a prelininary Signal and .then a series of signals, which will be read and understood, as 1 2 '3, and each time this disk is rotated this predeternined IOO IIC

, tinuous signal Will be sent, the circuit being system of signals will be sent, provided it is included in the circuit of the switch, and any one of the predetermined signals arranged on the circuit-breaking-wheels can be sent by moving the switch C', so as to complete the circuit through that particular circuit-wheel. If it is desired to send a continnous signal without interruption, I have arranged a circuit direct from the frame of the generator through the conductor 5 and the contact c, so that as long as the arnature is rotated a conclosed. It will thus be seen that by properly adjusting or constructing the circuit-breakers any number of signals can be sent, and they all being securcd upon the same shaft they can be arranged so that the intervals between the signals are even and regular, and the listener can readily deternine whether his particular call or signal has been made ornot.

WVhile I have th us described and illustrated what I consider the preferred embodiment of my invention, it is evident that many of the details of construction and arrangement of parts and circuits nay be varied without departing from the general and essential features of the invention, and I therefore do notdesire to linit myself to the precise mechanisn shown and described.
