lected portion of the vessel-say standing.

upon the bridge--to transmit certain conwntional signals to person located in a different part of the vessel; for instance to the engineer, in the engine room.

By my invention I seek to produce a marine telegraph in which the power employed in transmission of the slgnals 18 made by electric currents enerated altogether by 7 H muscular efforts ot the operator, so as to render the device independent of all outside sources of electric power, the mechanism bein g so arranged, however, as to avoid undue waste losses in transmission, so that no great muscular effort by the operator is required.

My invention further contemplates a marine telegraph employing a number of else it trio circuits each of which 1s normally.

dead in the sense that when my device is for the moment not in active use no part of any electric circuit is active, or is subjected to a difference of potential, or is energizedby a flow of current. a

In addition, my invention contemplates a marine telegraph having a number of drops located at the transmitting station, each and a number of drops located at the receiving station, each adapted to be set and restored electrically, the electrical connections and mechanism associated therewith being so arranged that theoperator at the transmitting station, before setting any particular drop at the receiving station, must first restore to normal condition all drops at the transmitting station;yand the operator at the receiving station, in order to answer the signal, must restore all drops atithe receiving station except one, which is directly associated with the particular signal to be answered. 1

Finally my invention comprehends a Fig. 1.

number of separate improvements in marine telegraph apparatus for the purpose of improving the general efficiency thereof.

Reference; is made to the accompanying drawings. forming a part of this specification, and in which like letters indicate like parts throughout the several figures.

Figure 1 is a fragmentary front elevation pf the mechanism at the transmitting sta- Fig. 2 is a section on the line 2-2 of Fig. 3, looking in the direction indicated by the arrows.

F 3 is a substantially central vertical section through the mechanism shown in Fig. 4 is a fragmentary section, showing theback portion of the mechanism of the indicator used at the receiving station.

Fig. 5 is a diagram of the wiring and.

electrical connections associated therewith. Big. 6 1s a dlagrammatic perspective of one of the drops employed, these drops be ing connected with the wiring as indicated in Fig. 5. i

The transmitter casing is shown at 6 and is mounted upon a hollow sup orting column 7. The casing is provide movable face plate 8 held imposition by screws 9. y y R A. gasketlO is carriedby the face plate, and renders the casing water-tight, as may be understood from Fig. 3. i it The face plate 8 is provided with a number of legends, as follows, Ahead,,Astern, Stop, Slow, Half Speed and Full Speed, the three last mentioned being duplicated as shown. These legendsmay be made with luminous paint, or otherwise rendered conspicuous as desired. a

A handle 11 is mounted upon a V-shaped arm 12, through which the legends may be read. This arm carries a pointer 13, and extends outwardly from a hub 14, which is secured rigidly upon one end of a tubular shaft 15, as may be understood from Fig. 3. The tubular shaft 15 is rocked within predetermined limits by movements of the handle 11, but has no other motion. A bearing 16, integral with the face plate 8, serves as a support for the tubular shaft 15, which extends through it,

The tubular shaft 15 also extends through with a rethe centering wheel. p p

" The operator therefore has only to stop a bearing 17 carried by and integral with a spider 18. This spider is by screws 19 secured to the face plate.

- The spider 18 carries an annulus 20 extending inwardly toward the tubular shaft 15,- and secured upon this annulus by aid of screws 21 is a contact disk 22.

Mounted rigidly upon the tubular shaft 15 is a disk 23, carrying an insulator 24;,

'and secured upon this insulator is a contact spring 25. This contact spring slidably engages a contact ring 26, with which it is always in contact, and from which it dissprings, by pressing the arms 31 toward each other, tend toforce the rollers 'into thenotches 29.v V V 7 These notches are so spaced and arranged that therollersBO, by occupying the notches one pair at a time, have a tendency to hold the centering wheel in definite predetermined 'positionsf That is to say, a s thehandle 11 is swung angularlyby hand, the operator fee-ls aresistance which varies step by step,

eausedbythe action of the rollers 30 upon the motion of the handle where he finds it .f the easi'esttoStop, in orderfto' 'leave it in such position" that the pointer 13 will indicate positively and precisely some particular le end. I Extending through .the tubular shaft 15 i -small shaft ,31.- Mounted rigidly upon th'el'outer end of thissliaft is acrank 32,

carrying ajhandle Agear'wheel'ii is niounted 'rigidly upon the opposite end of the shaftgl, and meshes with a pinion This pinion is mounted upon a shaft 36, which-isthe armature shaft of a direct current magneto 37. Thus themagneto is ac tuatedbyturning-the crank 32 by means of the handle 33. V V V Thehandle 11 and'arm 12 have nothing to do with" actuating the magneto but are employed in controlling the distribution of the 7 electric currents generated thereby.

A; door'is provided at 38, and adjacent this door is a terminalstrip 3}). 'Upon this terminal strip are mounted binding posts, one 6O 7 ofwhich appearsat 4:0. Back of the terminal strip is an elec ric bell 4:1.

The casing face is provided with peep holes42, 43,44, 15, 46,47 and 17, inthis instance seven innumber, an'dasso'cia'ted with anequal number of drops 48, 49, 50, 51, 52,

53 and 54. These drops each have the same construction, which may be understood from Fig. 6. A shutter a8, having in this instance the proximate form of a Maltese cross, is disposed adjacent a background, 48 relative to which it presents a contrasting appearance. This shutter may be coated with luminous paint, or otherwise illuminated as desired. It is mounted upon a rocking shaft 418, which also carries a permanently magnetic armature e81 Located upon opposite sides of the armature 48 are two magnets 1S 48 so arranged that in practice the drop is set by energizing the magnet l8, and is restored to its normal condition by energizing the magnet 18.

Referring more particularly to Fig. 5, the apparatus at the left hand side of the figure constitutes the transmitter and the mechanism at the right hand side comprises the receiver as indicated by legends. Adjacent each drop is a glass plate 51 carried by the casing face and sunken thereinto, for excluding the entrance of water.

Except for immaterial variations in the form of the casing and its location. the trans mitter has some part corresponding to each part of the receiver. The receiver, however, has a few additional parts not found in the transmitter, and these are shown structurally in Fig. ":lr, and indicated diagrammatically in Fig. 5, at the right hand side.

I will now describe these additional pa rls. A contact disk 55 is mounted rigidly upon the revoluble tubular shaft 15, and is provided with a notch 56. Dis osed adjacent the disk 55 is a stationary disk 57 made of insulating material and mounted upon this disk are contact members 58, 59, (30, 61, (32. 63, and 64, each having the form of a leaf spring, the one numbered 61 being shown in Fig. 4. The parts are so assembled and arranged that the contact springs normally engage the disk 55; but the notch 56, in passing each contact spring or in stopping adjacent the same, disconnects it from the disk 55, as shown in Fig. 4.

A contact spring 65 is in permanent engagement with the contact disk 55, as indicated at the right of Fig. 5.

Connected with the magneto 37 at the transmitting station are two wires 65, (36. From the wire 65 a wire (37 leads to the bell 41 at the receiving station. A wire 68 is connected to this bell and to a wire 69, which leads back to the transmitting station, and

is there connected to the wire 68. A wire 70 is connected to the junction of the two wires 66, 69, and connected to this wire 70, and in 7 parallel to each other with reference thereto,

are all of the restoring magnets 48, used in the several drops 48, 49, 50, 5 1, 52, 53, 5-1- at the transmitting station. These magnets are also connected to a wire 71, relatively to which they are in parallel to each other.

Connected to the wire 71 is awire 72, lead ing to the contact ring 26. A wire 73 is connected to the wires 71, 72, at the junction thereof, and is also connected to the wires 65 and 67 at their junction.

At the transmitting station. these wires are connected to the respective contact buttons of the disk 22, numbered 81., 82, 83,84, 85, 86 and 87. These wires are at the receiving station connected to the respective setting magnets 48 of the drops 48, 49, 50, 51, 52, 53 and 54. The magnets just mentioned are also connected to a wire 88, with reference to which they are inparallel. The wire 88 is connected to the wires 68 and 69, at the junction thereof.

Connected to the magneto 37 at the receiving station are two wires 89 and 90. A wire 91 leads from the wire 89 to the bell 41 of the transmitting station. Connected with this bell and with the wire 91 is a wire 92, to which all of the magnets 48, used at the transmitting station for setting the drops at said station, are connected in parallel. From the bell 41 of the transmit ting station awire 93 leads back to the rcceiving station, and is there connected to the wire 90. The wires 90 and 93at their junction are connected to a wire 94, which leads to a wire 95. Connected with this wire 95, and in parallel to each other with reference thereto, are all of the magnets 48 used for restoring the drops 48, 49, 50, 51, 52, 53 and 54 at the receiving station. A wire 96 is connected to the wires 94 and 95, and leads therefrom to the contact ring 26 at the receiving station. A wire 97 is connected to the wires 89 and 91, and leads therefrom to the contact spring 65 Seven wires 98, 99, 104 are connected to the contact buttons 81, 82, 83, 84, 85, 86 and 87 of the contact ring 22 at the receiving station, and lead therefrom back to the transmitting station, where they are connected to the respective setting magnets 48 of the drops.

The operation of my device is as follows: Assume that the vessel is stationary, that at each of the two stations the handle 11 occupies its middle or neutral position, and

that at each station the only drop registering an afiirmative indication is the one associated with the legend Stop, as may be understood from Fig. 1.

Assume further, that the oflicer at the transmitting station wants to send a signal for the vessel to move slowly ahead.

For this purpose he grasps the handle 11 and moves it in a contra-clockwise direction according to Fig. 5, so that the pointer 13 is ga ement with the contact button 83. A number of wires 74, 75, 76, 77, 78, 79, lead from the transmitting station to the receiving station, for the purpose of enabling the operator at the transmitting station to control the drops at the receiving station.

100,10i,102,103,and'

brought into registery with the legend Slow andwiththe peep hole 44, as well as into general association with the legend Ahead. This brings the contact spring 25 into en- 70 p to this point none of the drops are afiected. j i

The operator now grasps the handle 33 and turns it. briskly, so as to actuate the magneto 37 of the transmitting station. Direct currents are thus generated, and they flow through a circuit which may be traced as follows: magneto 37 wires 65, 73 and 71, thence in parallel through all of. the magnets 48 used for restoring the drops 48, 49, 51, 52, 53 and 54 at the transmitting station, wires 70 and 66, back to the magneto 37. This energizes the magnets 48 just mentioned, restores the drop 50 to its normal condition, and has practically no efiect upon the other drops at this stationfurther than to render itimpossi-ble for any of them to make anyindication except the normal or negative indication. Thus at the transmitting station all visual signals show positively and aflirmatively that the line of communication has been cleared, and that all drops at the transmitting station are in condition to register newindications.

. Another circuit energized by the magneto at the transmitting station is as follows: magneto 37, wires 65 and 67 to the bell 41 at the receiving station, and wires 68, 69 and 66 back to the magneto 37 at the transmitting station. This rings the bell 41 at the receiving station.

A third circuit energized bythe magneto at the transmitting station may be traced as follows: magneto 37, wires 65, 73 and 72, contact ring 26, contact spring 25, contact 105 button 83, wire 76 to the setting magnet 48 of drop 50 at the receiving station, wires 88,

69 and 66 back to the magneto. 1

This circuit causes the drop 50 at the re ceiving station to make an afiirmative or positive indication.

The 0 erator at the a receiving station, hearing t e sound of his bell 41 and noting the indication made by his drop 50 under stands that the vessel is to go ahead slowly. He desireshowever to make known the fact that he understands the signal. He also wishes to clear thedrops at the receiving station of all residual efi'ects of indications made previously.

The operator at the receiving station thereupon grasps the handle 11 of his instrument, and turns it to the left or in a contra-clockwise direction, as shown at the right in Fig. 5, so that the pointer 13 reaches the position associated with the particular indication received. This brings the contact spring 25 into engagement with the contact buttton 83. It also brings the contact disk 55 into such position that this disk is disconnected from the contact spring 60, owing to the presence of the notch 56, vas may be understood from Fig.5. This done, the operator grasps 111s handle 33 and by turning it briskly causes the magneto 37 at the receiving stationv to generate direct ourrents.

' y The following circuit may now be traced:

magneto 37 at the receiving station, wires .90 and '93 tothebell 41 at the transmitting station, wires '91 and 89Jback to magneto. This rings the bell 1:1 at the transmitting station. 7

Another circuit may be traced, as follows: magneto 37 of the receiving station,.wires 90 and 94 to wire 95,,thence in parallel through the restoring magnets 4L8 of the drops 58,

I 59, 61, 62, 63c and "64, contact disk 55, contact sprin 65' and wires 97 and '89 back to ma mas. "This clears all of'the drops at the receiving station except the one numberedv50, which is-vthesoned splay ng the particular signal to 'which an answer is 7 being given. This single drop remains unaii'ected'because, owing to the position of the'notch 56 of the contact disk'55, no ciristers an indication for apprislng the operator at the transmitting station that hissignal is understood,

The apparatus remains in this condition until another signal is to be transmitted,

whereupon theentire cycle of operations is repeated.

' Each time the operator at the transmitting'station wishes to transmita signal he grasps'the handlell and shifts-the arm 12 until the pointer 13 designates the particular legend'assoc'iated with the signal to be transmitted, and then energizes his magneto. Each time this isdone the operator at the receiving stationgrasps his handle 11, moves the arm'12 into'a position associated with the signal, and then energizes his-magneto.

Eachparticular signal sent from the transmitting station; to the receiving station involves the ener 'izing of some one of the wires 74, 75, 76,7 78, 79,80. 'Each time a "signal is answered involves the energizing' of some oneof thc wires 8, 99, 100, 101, 102, r
