This invention relates tomusical chimes, and more particularly to chimes that are electrically driven and controlled.
One object of the invention is the provision of an electrically driven chime in which the energizing circuit for an electric motor which drives the chime mechanism is manually controlled.
Another object of the invention is the provision ofa chime of sturdy and compact construction adapted to produce a predetermined sequence of musical notes when a controlling electrical contact is closed.
A further object of the invention is the provision of a chime having chime sounding mechanism driven by a single electric motor to produce a predetermined sequence of sounds of various tones, means being provided for starting the motor when desired but so arranged that the motor is open-circuited automatically at the end of the desired sequence of sounds.
Still another object of the invention is the provision of a device for producing a pre- 0 determined desired series of notes, the device being compact and of simple and cheap construction and adapted to operate efiectively over long periods of time without care or attention.-
Other objects and advantages of the invention will be apparent from the following description, the appended claims and the accompanying drawings, in which- Fig. 1 is a front elevation of an electrical chime embodying the present invention;
Fig. 2 is a side view of the chime operating mechanism, shown partly in section;
. Fig. 9 is a diagrammatic representation of the electrical connections;
Fi g. 10 is a detailed view partly in section, of the chime hanger; and
Fig. 11 is a top plan View of a chime mechanism contained in a modified form of housmg.
Referring more particularly to the drawings, in which preferred forms of the invention are shown, 10, 11, 12 and 13 represent chime sounders, preferably although of course not necessarily in the form of hollow tubes of brass or other suitable metal. When the chime SOLIIldBI'S' are of tubular form, they are preferably of the same diameter and of different lengths; as shown in Fig. 1, so as to produce tones of difierent pitch. The lower ends of the tubes are open, while their upper ends are closed by metal plugs 14 integrally connected at the tops of the tubes.
Some little distance belowtheir upper ends,
each tube is shown with a pair of small holes 15 through which the suspending cable 16, of loop form, extends. This loop extends up over a triangle of metal or the like 18, the
top ofwhich is slotted, and the sides of which project out beyond the sides of the tube so that the cable 16 will not be in contact with the upper end of the tube and thus interfere with the free vibration of the tube. The suspending triangles 18 are hung on pins 19 which project out from a cover plate 20 connected to the supporting housing box 21, and the pins aregrooved circumferentially to receive the tops of the cable loops whic rest directly in the grooves in the pins, as they extend down through the slots in the tops of the triangles 18. This form of sup port definitely locates the chimes with respect to their supporting pins. Preferably the pins are adjustably mounted for axial movement on the cover plate 20. The cover plate 20 and the housingbox 21 are preferably of sheet metal and the cover plate 20 is preferably suitably finished to present a pleasing appearance. A hood 20' is suitably attached to the cover plate 20 and provides an enclosure for the hangers and upper ends'ot the chime tubes. As shown, the hood 20' ex' late and tends the full width of the cover provides a housing having a close top and sides, and an open bottom having a defining edge some distance below the top of the chime tu es.
The main supporting housing box 21 may be recessed in a wall, indicated at 22, and contains the chime sounding mechanism designated generally 23. The housing box .21 is shown projecting out a little ways from the outer surface of the wall and is overlapped by the rearwardly extending flanges on the cover plate 20, these parts being connected by screws 24 to enclose the chime sounding mechanism and protect the same.
The chime sounders, any desired number of which may be provided, are sounded by hammers 26, 27, 28 and 29 which are so positioned as to strike the tubes 10, 11, 12 and 13 respectively through holes 30 provided in the cover plate of the housing. Each hammer is provided with a striking nose 32, of wood or other suitable material, the nose 32 being held by a nut 33 threaded on the stud 34. The noses 32 are long enough to project through the holes 30 in-the housing cover and strike the chime tubes when the hammers are operated, the holes 30 being somewhat larger than the diameter of the striking noses but preferably smaller than the nuts 33. As the only openings in the enclosing houslng are the clearance holes 30 for the striking hammers, and these are practically closed by the projecting noses 32 and the adjacent nuts 33 when in normal position, a substantially dustproof enclosure is provided for the chime actuating mechanism.
The hammers 26 to 29 inclusive are operated in predetermined order by means of an electric motor designated generally 36. The armature shaft 37 of the motor carries a flat disc 38 of aluminum or the like which revolves between shaded ole pieces 39 and 40 of an electromagnet 41 ormed preferably of strips of laminated soft iron. The poles 39.
and 40 are shaded by copper rings 42 and 43 respectively .to produce a turning effect on the disc 38 and consequent operation of the armature shaft 37 when the coil 44 of the electromagnet is energized by alternating current. The coil 44 is preferably designed for alternating current of commercial frequency at a low voltage, that is at a voltage very considerably below the ordinary 110 volt value. The energizing circuit for the coil 44, as shown in Fig. 9, includes the wire 46, the secondary 47 of a transformer 48, the wire 49, the contact fingers 50 and 51 and the I wire 52. When the contact fingers 50 and 51 are closed, the energizing circuit of the electric motor is completed, the primary of transformer 48 being connected to a house wiring circuit of 110 volts or other suitable commercial frequency. The transformer 48 is preferably located at a point remote from the sounding mechanism so that the wires lead- 6 ing to the sounding mechanism and its hous- 'wardly as indicated at 58 and is ing are of low voltage, minimizing the fire hazard.
The energized circuit of the electric motor is preferably controlled manually from a remote point. The controlling circuit for the energizing circuit includes the manually operable switch or push button 54, a magnet coil 55 and the secondary 47 at the transformer. When the push button 54 is operated to close the controlling circuit, low voltage current is supplied to the magnet coil 55 energizing the same so as to attract its armature 56 which is pivotally mounted at 57. One end of the armature 56 is bent uprovided with a knob 59 of insulating materia which, when the magnet coil 55 is energized, presses the contact finger 50 against the contact finger 51 to close the energizing circuit of the electric motor. When the push button 54 is in its open circuit position, the magnet coil 55 is not energized, but suitable means are provided, as will be presently described, to. maintain the armature 56 in its attracted position even though the magnet coil 55 is deenergized, until apredetermined, sequence of operations has taken place. The armature 56 carries in threaded engagement a brass adjusting screw 56'- which is provided to regulate the device for varying operating conditions.
The push button 54 may be provided in the usual location of a door bell of a residence so that the chime. can be used for in dicating when someone is at the door and 100 wants admittance, this indication being very pleasing and musical as distinguished from the harsh and annoying clatter of a bell, especially when the chime is so designed as to strike the notes of the Westminster chimes .105 or some other pleasing arrangement of notes.
It is to be understood, however, that the invention is not limited to this particular use of'the chime, as it may be used for giving an indication of any other fact. Thus it may 110 be used as a call for dinner, or manually controlled whenever desired to produce the pleasing notes intended.
When energized, the electric motor turns the shaft 37 which is rotatably mounted in 115 the side plates 60 and 61-, the rear ends of which may be held to a back plate-62 by means of angles 63 and suitable attaching screws 64. The back plate 62, which supports the operating mechanism, is adapted 120 to be fastened to the rear side of the houslng box 21 by screws 65 or in any other suitab e manner, permitting the ready removal of the entire operating mechanism as a unit whenever desired.
Qn one end of the armature shaft 37 is a p n on 67 which meshes with a gear 68. A plnion 69 fixed to the gear 68 drives gear 70, the (power being transmitted by a gear 71 fixe to gear and engaging with gear 72 180 secured b a set screw 73 to a transversely extending s aft74 which is parallel to the ar- Rigid with each of the pin discs 75 and 7 6- is a hub 77 provided with a set screw 78 which removably or adjustably fastens the pin disc on the shaft.
Below the shaft 74 is a transverse shaft 80 which is rotatably mounted in the side plates 60 and 61 and projects laterally beyond the plates providing a pivotal support for hammer supporting arms 81, 82, 83 and 84. These arms are mounted freely on the shaft 80 and each supports a rod 86 the upper end of which carries a chime hammer. The rods 86 are preferably rather heavy metal wires the upper ends of which may proj ect up through the studs 34 of the hammers to which they are secured by screws 35. One form of connection between the, rods 86 and their carrying arms is shown in Fig. 5 for example, the rod being reversely bent through spaced parallel holes in the arm 81, thus rigidly securing the arm to the rod in a simple manner. The rod extends down past its carrying arm and is provided with an upturned end 87 which ears against a long stud 88 suitably fixed to .and extending through the side plate's 60 and 61. When the upstanding lower end 87 of the hammer rod is in engagement with the stud 88, with the hammer at rest, the nose of the hammer isjust slightly spaced away from the adjacent side of its chime tube, but the lower end of the hammer. rod has suflicient flexibility,,due to its reversely bent form, so that when the hammer is raised and permitted to fall the nose of the hammer will strike the tube and then immediately rebound, being held from striking a second time by the yielding engagement of the upturned end 87 with the stud 88. The arrangement is such that the resiliency in the hammer does not overcome the kinetic energy during striking movements of the hammer but effectively acts against the weight of, the hammer when not in motion or when moving only slowly.
The pin disc 75 in Fig. 5 is shown provided with five pins 89, so arranged as to successively push the upper end of the .arm 81 to the left during normal clockwise movement of the pin disc. The hammer is shown in its normal position in this figure, but is about ready to be raised by the engagement of the lowest pin 89 with the upper end of the arm 81, and when this occurs the arm 81 will be rocked counterclockwise so as to raise the hammer. Then when the'pin passes along andfrees the upper end'of the arm 81 the hammer will fall due to its weight and strike against the chime tube with which it cooper ates. On the other side of the disc 75 is a second series of pins which engage with the arm 82 carrying the hammer 27. In the same way hammers 28 and 29 are operated by the pins on the pin disc 76, the arrangement of the various pins on the pin discsbeing such as to provide for a definite sequence of operation of the hammers to produce a desired tone series. As mentioned above, the pin discs are readily removable so that if desired they may be replaced by other discs having different arrangements of pins to produce a different tone sequence upon operation.
The electric motor is arranged so that it will continue in operation until a predetermined sequence of hammer movements has taken place and will then automatically stop. It will be noted that theshaft 74 carries a collar 90 which is loosely rotatable on the shaft and which is provided with opposed slots 91 at its end, the shaft 74 being provided with a transversely extending pin 92 positioned Within the slots mentioned. The slots 91 are somewhat larger than the diameter of the pin so that only limited rotational movement of the collar 90 on the shaft 74 is permitted, endwise movement being prevented by the pin 92 and a sleeve 93 secured to the shaft. A spiral spring 94 is connected at one end to a stud 95 on the collar and at its other 3.
end to the pin 92, this spring acting normally to hold the side 96 of the notch 91 against the pin 92 in a yielding manner. In other words it urges the collar 90 in a counterclockwise direction as shown in Fig. 6 with relation to the shaft 74. On the collar 90 is a flange 97 which is notched at 98, the notch normally receiving a downturned end 99 of the armature 56 as shown in Fig. 6, when the device is stationary. When the magnet coil 55. is energized by pressing on the push button 54, the armature 56 is drawn upwardly and its end 99 is pulled up out of the notch 98 thus permitting the shaft 74 to be rotated by the motor, the end 99 of the armature riding on the cylindrical surface of the flange 97 until it again drops into the notch 98. It will be seen that the armature 56 will be held in its up position so as to maintain the. electrical contact between the contact fingers 50 and 51 even though the push button 54 is only closed instantaneously. The energlzing circuit of the electric motor will thus be mainon the pin discs 75 and 7 6 willcause the successive operation of the chime hammers in a predetermined manner depending upon the arrangement of the pins in the pm discs.
At about the end of a complete cycle of operations the .slot 98 will-be in position to receive the downwardly extended end 99 of the armature 56, and the shaft74. will be moving. counterclockwise as viewed insFig.
a the rotating parts will'cause the shaft 74 to rotate through some little angle after the -motor has been deenergized thus winding up the spring 94 a little it bringing the collar 90 into the relationship shown in Fig. 8, with respect to the shaft 74. The shaft 74 will be positively stopped with the collar in this position, and with the armature end 99 engaging the right-hand side of the notch 98, see Fig. 6. As'the collar 90 is tensioned in a counterclockwise direction, at the end of a complete cycle of operations, as soon as the push button 54 is closed again and the magnet coil 55 energize again to attract its armature, the collar 90 will spring forward, or in a counterclockwise direction as shown in Figs. 6 and 7 the very instant that the armature end 99 is removed from the notch. Without this arrangement, or its equivalent, closure of the push button 54 for only an instant. might result in the armature end 99 falling back into the notch before the moving parts get started, but with the device shown the armature end 99 cannot get back into the notch as the latter is moved forward by the spring 94: as soon as the armature end is withdrawn, and the device is thus compelled to complete a full cycle of operations until it is automatically stopped again by the fall bf the armature end 99 into the notch 98.
It will now be clear that there is an energizing circuit for the motor and a controlling circuit for the energizing circuit, the controlling circuitbeing such that it need be only closed for an instant, or such that it can be maintained if desired. Thus when the device is used in place of a door bell for giving a pleasant musical indicatlon when someone is at the door, the vlsiting party need only press the push button 54 for an instant, or he can press it three or four times I in succession but regardless of how the push button 54; is operated, and regardless of how long it is maintained in circuit closing position the desired signal of the chime will be produced.
All of the electrical wires leading to the housing or container box are of low voltage as the transformer 48 is provided at a point remote from the box, in suitable location.
The box, when recessed in thewall, may have outlet holes 100 preferably back of the. face of the wall, through which the w1res leading to the electric motor and the magnet coil export. 103 designates a wall or other support to which the chime housing is fastene In this case the chime housing embodies a flanged supporting plate 104, the laterally extending flanges 105 of which may be screwed to the support 103. The supporting plate is preferably of substantially flattened U-shape, and its larger face or wall 106 serves as a support for the chime tubes 107 and also for the hammer operating mechanism 108, the side plates 109 of which may be secured directly to the face 106 by means of the angle pieces 110. The striking noses of the ham mers operate through holes in the face 106 just as they do through the cover plate 20 in the form of the invention first described.
As the chime tubes 107 are hung from the studs 111 connected directly to the face 106, it will be understood that the relationship of the chimes with respect to the hammers at the top of the supporting plate 104, being removably fastened in any suitable manner as by a suitable snap connection at the upper sides of that portion of the supporting plate which projects out away from the wall.
