Gate/7 f. Lim'ez Patented Jan. 1, 1929.
' Application filed June 15, 1925.
My invention relates to a new and useful improvement in a bell attachment for an d accordion, which will be electrically operated, so that the one playing the accordion,
upon sounding the notes, which are operated by keys, will also energize an electrical mechanism for sounding bells or tubes of varying pitch, so that the player playing the accordion may produce, in addition to the usual music of the accordion, an effect resembling the playing of orchestra bells. To provide a mechanism which will -result in this effect is oneof the objects of the present invention.
Another object of the invention is the provision of a mechanism of this class, which may be easily and quickly connected to different keys, so that the player, when operating the instrument, will be able -to sound the bells in a diflerent scale than that in which the keys of the accordion are played.
Another object of the invention is the provision of a mechanism for regulating the volume of the sound produced y the bells, by a closing of a circuit to a. shutter operating mechanism.
Other objects will appear hereinafter.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood from a'reference to the accompanying drawings which form a part of this specification and in which,
Fig. 1 is a top plan view of an accordion, showing the auxiliary box in elevation,
Fig. 2 is a diagrammatic view illustrating wiring used in the invention,
Fig, 3 is a transverse sectional view through the movable contact bearing member,
Fig. 4 is a fragmentary sectional view showing one of the keys of the accordion in elevation and illustrating the contacts operated through a pressing of the accordion ke Fig. 5 is a fragmentary sectional view illustrating the shutter operating mechanism. Fi .6 is a fragmentary top plan view of the evice illustrated in Fig. 3.
As shown in the drawings, the invention is adapted primarily with an accordion 9 having a keyboard 10, upon which 1s rockmgly mounted keys 11, which closely resemble the keys of a piano and each of which is' adapted for sounding a separate note, when the wire 26 to the positive Serial No. 37,119.
the accordion is played. Mounted on the unersurface of each of the keys 11 is a contact13, which is suitabl wired by the wire 14, which passes throug a cable 14 to the negative pole 14 ble source of electrical energy may be used instead of a battery, as will be evident from the description. Mounted on a supportin board 15, which is carried by the keyboard 10 is a contact 16. trically connected by means of the wire 31,
as shownvin the diagrammatic view to a con- V tact plug 30. This contact 30 is carried on a swlngably mounted support 29, which is pivoted on a rod 28, sultably supported in the housing or box 17. The support 29, in addition to being swingably mounted on the rod 28, is also adapted for slidable movement on'the rod 28, so that the support 29,
which is of less length than the rod 28, may
be slid from one end of the rod 28 to the other. The plug 30 is adapted to co-operate with a socket contact 24, which is mounted upon a supporting wall 23, positioned in the housing or box 17. The contact 24 is electrically connected by the wire 25 to magnetic coils 26, adapted for operating the hammer to ring the bell 27 which is positioned in the housing or box 17. The specific structure coils 26 and the bells 27 is not set out, inasmuch as this specific structure forms no part of the invention, the operation of this mechanism being of a well known type. In the simplest construction there is intended to be mounted in an desirable manner in the housing or box 1; twelve of these bells 27, which are tuned in. the chromatic scale from C to B, either low or high pitch. The
arrangement is such that the magnets will cause the hammer to strike the bells, when the circuit is closed through the magnetic coils 26. Instead of the bells 27, it is, of course, evident that metallic tubes properly tuned may be used.
As shown in the diagrammatic view, the
magnetic coils 26 are suitably connected b pole of the battery, so that, when thekey 11 is pressed to bring the contacts 13 and '16 into engagement with each other and the plug 30 is in engagement with the socket contact 24, a circuit will be closed through the magnetic coils 26 to effect an operation of this mechanism.
In operation, the player will move the no of a battery. Any suita- 60 This contact 16 is elec- 65 socket 80 of the magnetic g5 contacts into engagement with the contacts 24 preliminarily to playing. The pressing down of the keys .11 will then serve to close the circuit through the magnetic coils 26, to efi'ect. a ringing of the bells, or\
keys 11 and the pole 14" of the battery, so
a sounding of the tubes, as the case may be. On the keyboard of accordions, there should be at least twenty-five keys and each of the keys is provided with a contact terminal to 00-0 erate with another contact terminal carrie by the keyboard, these terminals being arranged and constructed as described. In the diagrammatic view, I
have shown a wiring for a keyboard of thirty-six keys, although the number of keys on the keyboard will not materially affoot the use or operation of the invention. The greater the number of keys, of course, the more contacts there should be with an increased amount of wiring. In the diagrammatic view, the keys have been indicated' by sets of twelve, the twelve keys indicating the twelve notes in the chromatic scale. On the slidable contact bearing member 29, I have illustrated but twelve contacts, which is ample in the simple structure where only twelvebells or brass tubes.
are used. Should it be desirable, as undoubtedly would be the case in more elaborate structures, to have more than twelve bells mounted in the housing or box 17,
the number of contacts on the slidable .con-
- tact bearing member 29 would have to be correspondingly increased, the number of these contacts on the contact bearing member 29 being equal to the number of bells or tubes mounted in the housing or box 17. As shown in the diagrammatic view, each key of each set of twelve is electrically connected to the corresponding key of every other set of twelve, so that a closing of the contact of one of the keys of either of the sets of twelve would have the same effect as' the closing of the contacts of either of the other corresponding keys of the other sets of twelve, the wiring being a connection in series. In operation, the one playing the instrument would, before plugging the contacts 30 into the contacts 24, select the scale in which he desires the bells to be played. For instance, if the contact at No. 1, which is carried by the contact support 29, should be plugged into the contact 24 at No. 1, the keys 11, when played, would cause to be rung a bell tuned accordingly. However, should the contact No. 1 on the contact support 29 be plugged into the contact socket 24 at No. 5, the bells would be played in a diflferen't scale than the scale of the keys, so that the player would. be playing the piece of music on the keys 11 in one scale and playing the same piece on the bells in another scale. In this way, with the simple structure shown in the drawings, the-player has a selection of twelve scales in which to The switch 11 may be.
positioned atany desirable point on the key- 7 board 10.
The box 17 should be constructed so as to provide a desirable sounding chamber, but the specific structure of this box also forms no part of this invention, and therefore is not set forth in detail. The box 17, however, is provided with an opening 18, over which is positioned a suitable screen 19. Mounted on the wall 17 of the housing, or box, 17 is a solenoid 22, which is connected electrically,
as shown in, the diagrammatic'view, a suitable switch 22 being provided to permit the operator to energize the solenoid 22 at will. The cord 21 is connected to operate swingingly mounted shutters 20 which are positioned in the opening 18. These shutters 20 and their specificconnection to .the solenoid are of a well known type and their detailed structure forming no part of this invention, is consequently not shown. The operator may, at will, open or close the switch 22', so that the shutters ma opened or closed to increase or diminis the volume of sound emanating from the box or housing 17 when the bells are sounded.
The structure, as illustrated, is a simple one to produce the eifect desired, and the arrangement shown afi'ords the operator a llpge range of scales in which to play the While I have illustrated and described the preferred form of structure, I do not wish to limit myself to the precise form of structure shown, but desire to avail myself of such variations and modifications 'as come within the scope of the appended claims.
