SIGNALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 474,853, dated May 1'7, 1892.

Applioation filed September 1'7, 1889. Serial No. 324.181. (N0 model.)

To all whom it may concern:

Be it known that I, BERNIOE. J. NOYEs,of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Signaling Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In United States Patent No. 359,688, dated March 22, 1887, an electric signaling apparatus is shown, comprising signal-transmitters located at transmitting-stations and a receiving apparatus located at a receiving-station operatively connected in the signaling-circuit, the said signal-receiving apparatus comprising a register and a bell or other indicating signal, the latter responding to some but not to other signals.

In carrying out the invention the bell was arranged to be included or connected in circuit when desired that it should operate, and a distinguishing impulse was employed to effect such connection, the impulse therein shown being one of dilierent duration.

In another application filed by me concurrently with this, Serial No. 324,180, a signaling apparatus is shown comprising a register and a bell, both of which are normally included or operatively connected in the signaling-circuit, and a switch is employed to render inoperative, disconnect, or cut out the said bell for some signals and not for others.

This invention, generically showing means for carrying out substantially the results of said application, Serial No. 324,180, has for its object the provision of novel and specific devices by which said results may beeheaply and efficiently carried out.

In accordance with this invention the signal-transmitters are constructed and arranged to transmit the signals by any well-known kind or character of impulse, and for some, or in eonj unction with some, of the signals a distinguishing impulse is transmltted, and at the receiving-station a register and a bell orother indicating signal are connected 1n the signaling-circuit, both of which respond to all slgnals unless one of them-as the bell or indicating signal-*shall be cut out or disconneeted.

As herein shown, a time-switch is placed at the receiving-station, the movement of which is controlled byan eleetro-magnet. Theswitch is so timed that when moved it will disconnect or cut out the bell for a sufiicient length of time to permit the reception of the signal. The electro-magnet of said time-switch is effected by the distinguishing impulse.

Figure 1 shows in diagram an electric signaling apparatus embodying this invention, and Fig. 2 a diagram of a central office or receiving station to be referred to.

The signaling-circuit a connects the signalboxes at the substations with a signal-receiving station. At each sub-station a multiplesignaling apparatus is shown of some suitable construction, many forms being now well known, the one herein shown, however, comprising a series of wheels 2 3 4t 5, arranged on a shaft 6, which may be revolved by any suitable motor, a series of contact-pens 7, (one for each signal-wheel,) and a selecting-cylinder 8, turned into different positions by means of a pointer p. This signal-transmitter when constructed as herein shown or otherwise must be arranged to transmit the signals by impulses of any well-known kind or character, and also transmit with some, or in conjunction with some, signals a distinguishing impulse. As shown in Fig. 1, the transmitter is arranged in a metallic circuit and the regular signal impulses are sent over that circuit, while the distinguishing impulse is sent over a ground-circuit.

At the receiving-station (see Fig. 1) a receiving-relay b is included in the signalingeircuit, the armature Z) of which closes and opens a local circuit 12 containing aloeal battery b a register b and a bell 12 An electro-magnet c is also arranged at said receivingstation, included in aground tap orbraneh 0, leading from the main signaling-circuit. The armature c of this electro-magnet c has attached to it, one member of a switch cl, arranged to open and close a shunt-wire d for theloell 11 When the armature is retracted,

the bell b is not shunted out, and hence will respond to the movement of the armature b of the relay Z); but when said armature c is attracted the said bell b is shunted out and will not respond.

ration.

The armature c has co-operating with it a retarding device,herein shown as comprising a sector e, engaging a pinion e, fixed to a shaft carrying a ratchet-wheel 6 a toothed wheel 6 arranged on said shaft and carrying a pawl e which engages the said ratchet-wheel, and a fan-escapement e mature 0 can move toward the poles of the electro-magnet c quickly, but will return to its normal position by means of the retractile spring a slowly.

A switch 01, as shown, comprises a stationary block or armature and an arm, the latter being attached to the armature 0 The block has quite a long contacting-surface, so that t ,t1 .imp.ulse is sent overa ground-circuit,

including the relay 0. On the reception of this signal the first impulse draws the armature into contact with the poles of the elect agnet c and closes the switch d, so that as the otherimpulses are transmitted the bell b will be shunted out.

I have arranged the switch at so that on the reception'of aground impulse the switch will beclosed before the armature b can close the local circuit, although in practice the action will b substantially simultaneous, the object being to close the switch before the bell b will operate.

Referring to Fig. 2, the electro-magnet c is included in the signaling-circuit, and instead of being responsive toground impulses alone,

or to an impulse difterentiin character to the regular signal impulses, the distinguishing impulse employed will be one of different du- To effect the desired results, the retarding device is arranged to retard the move- As represented, the ar ment of the armature c alike or substantially so in each direction, so that on the reception of an impulse of long duration it will retract sufficiently to close the switch and shunt out the bell 19 The switch is arranged to remain closed during nearly the whole movement of the armature c and the retarding device is timed so that the switch will remain closed a sufficient length of time to receive the signal. Thus it will be seen that in either instance shown the same results are carried out in substantially the same way.

I claim- 1. In an electric circuit, a signal-receiving station containing a register and a bell operatively connected with the said circuit and normally responsive to the signal impulses, a controlling device for rendering said bell nonresponsive, consisting of a shunt-switch and retarding device for it, andan electro-magnet for said shunt-switch responsive to .a distinguishing impulse, combined with a signaltransmitter, also connected with said circuit and contained in a box, and a circuit-changer for transmitting said distinguishing impulse to effect the operation of said electro-magnet, substantially as described.

2. In an electric circuit, a signal-receiving station containing a register and a bell operatively connected with the said circuit and normally responsive to the signal impulses, a controlling device for rendering said bell nonresponsive, consisting of a shunt-switch, a retarding device for it, and an electro-magnet in another circuit for said shunt-switch responsive to a distinguishing impulse, combined with a signal-transmitter, also connected in said circuit and contained in a box, and a circuit-changer in another circuit for transmitting said distinguishing impulse to effect the operation of said electro-magnet, substantially as described.

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