ELECTRICALZINDICATOR.

SPECIFICATION forming part of Letters Patent No. 324,635, dated August 18, 1885.

Application filed September 15, 1884. (No model.)

To all whom/it may concern:

Be it known that I, MURRAY Bncon, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Electrical Indicators, of which the following is a specification.

My invention consists of an improved electrical indicating apparatus, more especially intended for use on steamers, to indicate in the pilot-house in which direction the engine is running, and whether the signals of the officcr in command to the engineer are being properly obeyed. For this purpose I combine with the reversing and throttle-valve levers, or other suitable parts of the valve-gear of the engine, electrical switches connected to the indicator, which is placed in the pilothouse, or wherever it is needed, the switches being operated by the movement of the valve levers to throw into or out of circuit one or both of two magnets or pairs of magnets, which control apointer to indicate ahead, back, or stop, or similar signs, according to the position of the switches, due to the movement of the reversing and throttle valve levers of the engine.

In the accompanying drawings, Figure l is a diagram illustrating the circuits and general arrangement of my indicating apparatus. Fig. 2 is an outside View of the indicator proper, to be put up in the pilot-house. Fig. 3 is a sectional view of the indicator on the line 1 2, Fig. 4, and Fig. 4 is a vertical transverse section of the same.

Referring to Fig. 1, R is the indicator-box in the pilot-house or other desired point, and L is a rocking arm connected with and operated by the reversing-lever of the engine, while L is an arm controlled by the operatinglever of the throttle-valve.

S is an electrical switch, having a pivoted arm, 3, adjustably connected by a link, Z, to the arm L, and adapted to make connection with either of two spring contacts, 1 and 2, according to the position to which the reversing-lever is moved. The arm L is connected by an adjustable link, Z, to the movable arm 5 of a switch, S, with a single contact, 3. The contact I of the switch S is connected, through a conductor, 5, with a pair of eleotro-magnets, E E, the poles of which face each other, and thence the circuit through a return a wire, 4, containing a battery, M, and the switch S, to the switch-lever s. The contact 2 is similarly connected, through a conductor, 6, to a pair of electro-magnets, E E, (at right angles to the others,) and thence through the common return-wire 4 to the same switohlever s.

In each of the two circuits is included an audible signaling device differing from that in the other circuit. Thus in the circuit 5 I have shown an electromagnetic vibrator, C, with a bell, while in the circuit 6 I have ineluded a buzzer, B, orvibrator without a bell.

Between the poles of the two electromagnets is an armature, A, which carries or con trols a suitable pointer-finger, P. When the throttle-valve of the engine is olosed,the lever s of the switch'S will be free from the contact 3 and the circuits through either pair of magnets open, so that the armature A will be unengine backward, as indicated in the diagram,

the switch-lever 8 makes connection with the contact Z and the circuit through the electroniagnetsE E and clear call-bellGis closed. The bell C will ring and the armature A will be attracted to the position indicated in Fig. 1, and the finger P will point to the word back on the dial.

When the revcrsing-lever of the engine is thrown over to go ahead, the lever s will come into contact with 2, to close the circuitthrough signal B and electro-magnets E E, which, acting on the armature A, will cause the pointer to be turned to indicate ahead. It will thus be seen that each movement of the throttlevalve and of the reversing-gear of the engine will be indicated in the pilot-house even be fore the engine responds.

Thus when the to show the-word Open when the switch is thrown open.

It will be understood that more than one of these indicators may be included in the cir-. cuit, and located at different points on the vessel.

' I will now proceed to describe the detailed construction of the indicator-box as illustrated in Figs. 2, 3, and 4.

The case D is preferably of the cylindrical form shown, with dial-platesd d on opposite sides having glass fronts d d. Within the case is a brass frame, F, to which the case is secured, and within the frame are mounted the four eIectrom-a'g-nets E E and E E, these four electro-magnets forming, in effect, part of the frame, since they connect the front and. back plates, f f, of the frame F. These electr0-magnets have polar extensions 0 eand e e projecting inward toward a central point,

which is the axis a of the armature A. This. axis is mounted in bearings in the plates f f 7 and, projecting through the dial-plates d d,

carries at itsopposite ends the two pointers P.

To one of the plates f f, at one side, is 'secured the vibrator call-bell C, while to another part of the frame is secured the buzzer B; but as these maybe of any suitable and well- 1 known construction it will be unnecessary to 5 describe them in detail. I K In the dial-plates d d are out 'curvedfslots: d (P, and behind each dial is a reversible: plate, h, carried by an axis, H, mounted in: bearings in the frame-platesf f, and having a chain pulley or wheel, h, over which passes I a manipulating chain or cord, h Bygpullingi one or other end of this pendent chain or cord the plates h may be turned. The axis H also carries the electrical switch T in the returncircuit, and which consists of a contact-arm, t, making contact with a spring-finger, t, Fig. 3, in the return-circuit, when the reversible plate is in one position, and with an insulated I stop, 1?, when in the opposite position. On; the face of each plate h are the'words Ahead, Stop, Astern, and Open. When the; axis H is turned to throw the arm t into contact with the finger t, the words Ahead,

Stop, Back, all show through thecur-ved slot in the dial, as shown in Fig. 2, while The dial-plates are preferably of ground glass or similar material which will allow the letters to be seen at night when a light is arranged in'side the case.

On the outside of the case are three binding posts, p 10 19 to which the conductors are to be connected, and to which the terminals inside the box are connected; but it has been thought less confusing not to illustrate the circuits in Figs. 3 and 4. v

Instead of making the case of the indicator of the form shown and described, it may be of rectangular or other form and only one dial need be employed.

I claim as my invention 1. The combination of the throttle-valve lever of-an engineand an "electrical switch operated thereby with an electrical indicator controlled by said switch, substantially as set forth.

2. The-combination-of the 'reversing-l'ever-of an engine andan electrical switch control-led thereby with an electrical indicator operated by said switch to show in which-direction the engine is running, substantially asset forth.

3. The combinati'on of the valve-levernofsan engine and :an electrical switch controlled thereby with an indicator consisting of two electro-magnets and an armature, a pointer operated thereby, and a dial, substantially as 4. The combination of a valve-lever o-fan engine and-an-electrical switch operated thereby with an indicator consisting of a dial, pointer, and two elect-ro magnets controlling the pointer, each electro-magnet having an audible signal in circuit differing in-character from the other, substantially as described.

5. The combination of the slotted dial-plate and pointer with an axis carrying-a reversible sign-plate, andaswitch' controlled by said axis, substantially as set forth.

6. The combination of the slotted diahplate with an axis controlling aswitch and carrying a reversible sign-plate, a pulley, and amanipulating-chain, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MURRAY BACON.
