REX IRELAND, OF EDISON, OHIO.

AUXILIARY SIGNAL DEVICE.

To all 'whom it may concern:

Be it known thatI, REX "IRELAND, a citizen of the United States, residing at Edison, in the county of Morrow and State of Chio, have invented a certain new and useful Improvement in Auxiliary Signal Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to devices for operating electric bells, and more particularly to telephone signal bells having auxiliary signal or extension bells remote from the telephone.

One of the objects is to provide a very simple mechanism connecting an auxiliary bell, or series ofbells, to the operating mechanism of the usual signal bell of a telephone, so that they may be rung whenever the usual or main signal bell isrung.

Another object is to arrange the electric circuits connected to the extension bells so that a separate source of current may be used for operating them independently of the circuit for the main signal bell of the telephone. For example, the main bell may be operated by alternating current from a magneto and the auxiliary bell by direct current from a battery. rlhis enables easy attachment of the auxiliary bell circuit without disturbing the main bell circuits.

Further objects will become apparent in the detailed description of my device in connection with the drawings.

In the drawing, Figure 1 is a somewhat diagrammatic view, showing the arrangement ofthe bells and the circuits connecting them; Fig. 2 is a perspective view of the device for operating the `main signal bell, and the arrangement of the parts for closing the circuit through the auxiliary or extension bell or bells; Fig. 3 is a vertical section through the operating parts.

Referring to Fig. 1, the numerals 5 and 6 indicate the gongs of the usual signal bell of thetelephone, mounted on the box inclosing the magnet 8 and the device for ringing this bell. 9 indicates the clapper carried on the arm 10, which extends through the side of the box 11 and is carried by the armature 12 of the magnet 8. The magnet 8 may consist `of cores which` are surrounded by coils oppositely wound, and thus adapted to alternately attract the Patented A110'. 18, 1914.

ergized by an alternating current. A usual `source of current for these magnets is a magneto generator, indicated at 14, having wires 15 and 16 leading to suitable binding posts on the side of the box 11, which are connected to the magnet 8 by wires 18 and 19. lThis circuit may be opened or closed a suitable switch, indicated at 20.

The parts heretofore described comprise lthc usual means for operating a telephone g bell. My device consists of a mechanism op- ,erated automatically by the action of the magnet mentioned for mechanically closing a local circuit through one or more auxiliary y bells, as, for example, the bell 2l comprises the closing device, to be hereinafter described, and the wires 22 and 23, switch 24,

lwirc 25, bell 21, wire 2G, battery 27 and i wires 28 and 29. The bells 21, of which there may be any number, are ofthe ordinary call-bell type, being operated by a direct current :in a local circuit, which is alterends of the pivoted armature 12 when en J nately opened and closed `as the clapper oscillates. Other signals, additional or` substituted, may be operated by this local circuit; for example, an electric light, as indicated at 31.

Referring to Figs. 2 and 3, 30 indicates one side of the box 11 on which my device is carried. The magnets` 8l are shown as mounted on a suitable bracket 32 secured to the side 30 of the box l1. The armature 12 has a downwardly projecting wing 4:3 having at: its lower end a gudgeon 33 engaging a bracket 35 on the upright bar 3G. A corresponding gudgeon 311 projects from the upper edge of the armature 12 and engages the forwardly bent end of the upright bar 36. The armature is thus vertically pivoted and when the magnets 8 are energized it swings on these pivots, causing the arm 10, which extends through the hole 37, to oscillate to ring the usual bell. The arm 36 is carried by a bracket 38, which is shown as formed of a flat metal strip having a portion 39 bent at right angles thereto and screwed to the side 30 of the box 11. Two arms 40 and L-l are formed integral with the outer end of the bracket 38. Passing through these arms are small screws 42 having conical-shaped points which engage suitable recesses in the sidesof the upright bar 36, thus the bar 36 is pivoted on a horizontal axis, and it will be seen that the armature 12 is pivoted on an axis at substantially right angles thereto. Secured to the bracket 38 is a metal strip 44 having a portion 45 rising diagonally from the bracket, and a portion 47 rising` from the latter port-ion substantially at right angles to the bracket. A screw 48, forming one of the contact members of the local circuit, is threaded through this portion 47, and is adapted to abut against a corresponding contact spring 49 carried by the arm 36, when the armature 12 carried thereon is drawn toward the magnet 8. Attached to the bracket 38 is the wire 28 forming part of the circuit to the extension bell. The wire 21 is connected to the strip 44, which is insulated from the bracket 38, and it will be seen that, when the armature 12 is drawn toward the magnet S, a contact will be made at points of the screws 48 and the spring 49, closing the circuit through the wires which lead to the auxiliary signahthe current passing through the arms 40 and screws 42 to the bar 36 and thus to the contact spring 49. Between the two

arms

49 and 41 is a downwardly de pending portion 50 to which is attached a suitable spring 51 adapted to hold the armature normally away from the magnet 8. As shown, this portion 50 has an adjusting screw 52 threaded through its lower edge to which is attached the end of the spiral tension spring 51. At its upper end the bar 36 abuts against the downwardly turned end of a magnet 13 and limits the movement caused by the spring 51.

The operation of the device is as follows: When the magneto generator 14 is operated, the magnet 8 is energized by an alternating current through the circuits described and the armature 12 is drawn toward the magnet until the spring 49 abuts against the screw 48, by means of the bar 36 swinging on its pivot 42 connecting the circuit through the wires 21 and 2S and the wires leading to the extension bell or bells. 1While in this position, each end of the armature 12 is alternately attracted by each coil of the magnet 8 and the arm 10, carrying the clapper 9 is vibrated, thereby giving the usual signal by striking the gongs 5 and 6. During the time the magnets 8 are alternately energized the attraction of either magnet for the armature 12 is sufficient to hold the spring 49 in position to close this circuit. Throughout the time that the magnet 8 is energized and the clapper 9 thus vibrates back and forth, the local circuit is continuously connected through the extension bells, which are rung by means of the battery 26 energizing the magnet of each bell.

1t will be seen that any number of extension bells 21 of the ordinary electric hell type may be employed, and each of t-hese bells may be rung by means of the battery 27, however remote from the telephone bell. By the use of my device, it also becomes possible to use any convenientk battery 27 g for example, the battery used to ring the door bell might also be connected with the extension bell or bells, and used to ring them.

One of the advantages of my device is that the movable carrier may be substituted for the present carrier in the ordinary telephone, providing a very convenient method of installing` an auxiliary signal system, and one which may be used for various kinds of electrically-operated signals..

Having thus described my invention, what I claim is: Y

1. The combination of a bell having a magnet, a vibrating armature, a movable carrier on which the armature is movably mounted whereby the armature may move on the carrier independently thereof to ring the bell when the magnet is energized, and an auxiliary signal on an independent circuit having contacts closed by the movement of the carrier and held closed by the attraction of the magnet when energized.
