Definitions
- the invention relates to a mechanical music box comprising a set of parts capable of generating, in an analogous manner, one or more chosen melodies, the musical tinkling of which is obtained by a modular number of spring blades, that cams of lifted, judiciously arranged on a rotating drum and comprising all the notes of the melody (s), raise alternately then release, to produce in their relaxation the desired melodic notes.
- This invention relates to the field of mechanical musical instruments which can be applied, without being limiting, to mechanical musical pieces relating to watchmaking and silversmithing movements, dampers, songbirds, toys, stuffed animals, boxes, various displays and charms.
- these two half-frames enclose the components, placing them on radially open bearings and located in the median axis of the joint plane. This specificity facilitating the holding and assembly of the components represents, as will be demonstrated later, the organization of the design and the general invoice of the new product.
- Figure 1 showing, on an enlarged scale a front view cut along AA of Figure 2, the music box in the assembled state.
- Figure 2 showing, on an enlarged scale a side view cut along BB of Figure 1, the music box in the assembled state.
- Figure 3 showing, on an enlarged scale a side view cut along C-C, of a mounted musical blade placed in front of one of the lifting cams of the musical blades distributed on the roller.
- Figure 4 representing, in an approximate size, a fairly representative front view of the music box with eighteen notes.
- Figures 1 to 3 represent, without this being a single representation or limiting to other types, sizes and various possible adaptations, a music box of eighteen musical blades (18 notes) operating in a similar manner and comprising, in an approximate order of their assembly, two half-frames 1 which, when placed end to end, enclose the various components 2 to 15, themselves constituting, according to the preferred embodiment of the invention, the central axis 2 supporting, two cores 3, two spiral springs 4, two drums 5, two rollers 6, a winding rod 7, a winding crown 8, urine or two PTO rods 9, a large toothed wheel 10, an average toothed wheel 11, a small toothed wheel 12, a worm 13, two flywheels regulating the musical tempo 14, the eighteen spring blades 15.
- Two half-cases 16 enclose the assembly.
- the half-frame 1, component support part includes the means of holding the components and is presented as a half-frame which, placed end to end, encloses on their bearings and respective locations lf, lg, lh, li, lj, lk, ll, all components 2 to 13.
- the spring blades are placed individually in grooves lm, the rear part of which holds them axially In and radially lm.
- the central axis 2, support part of the cores 3, of the main spring or springs 4, of the drums 5, of the rollers 6 with lift cams 6a, consists of a cylindrical rod supporting a toothed wheel 2a for winding the main springs 4, the straight streaks 2b used for the drive.
- the core 3, support part of the main spring 4 consists of a ribbed central channel 3a used for driving the inner part of the main spring 4, of a lateral flange 3b guiding and closing the drum 5.
- the main spring 4 the driving part of the musical instrument and the adaptable power take-offs, consists of a steel band winding, the ends of which are folded in the form of hooks used for winding it and for driving the drum 5.
- the drum 5, support part of the rollers 6 and housing of the main spring 4 which, by means of its toothed crowns 5b, 5c, 5d, serves to drive the toothed wheel 10 belonging to the musical tempo regulator, the socket (s) force 9, except that when there is a second drum 5, the second drum 5 does not have a toothed wheel 5c and therefore does not drive the force rod (s) 9.
- roller 6 program part of the memory of the melody determined by the cams 6a, is placed by driving 6c and guidance on the drum 5, the cams 6a being made by pushing back from inside the tube 6b
- the winding stem 7, part linked to the winding key 7a actuates the toothed crown 8, by means of a torque limiter formed by inclined notches 7b and bearing against the spherical part 7d against the central axis 2.
- the toothed crown 8, part linked to the winder is placed on the winding rod 7 and serves to drive the toothed wheel 2a placed on the central axis 2 and to tension the main spring 4, the stop 8b serves to prevent, by l 'through the groove 5e, a loss of the main spring 4.
- the power take-off rod or rods 9, parts of motor connections external to the music box are formed by a cylindrical rod 9a and a toothed wheel 9b which is driven by the toothed crown 5c of the drum 5.
- the large toothed wheel 10, second part linked to the musical tempo regulator comprises two rows of pinions 10a 10b, meshing from 5d for 10a and having for bearings the two cylindrical bearings 10a.
- the medium toothed wheel 11, third piece linked to the musical tempo regulator comprises two rows of pinions 11a 11b, meshing from 10b for 12a, and having for bearings the two cylindrical bearings 11a.
- the small toothed wheel 12, fourth part linked to the musical tempo regulator comprises a row of teeth 12a and a row of pallet teeth 12b driving the worm gear meshing from 11b to 13a of the worm 13 and having bearings the two litters cylindrical 12b.
- the endless screw 13 the fifth part linked to the regulator, is placed perpendicular to the axis of the toothed wheel 12 and is placed on the bearings 11, two flat 13c limit centers and drives the flywheels 14.
- each arm 14b carries at its end a counterweight 14c promoting the expansion of its arms.
- the musical blade 15 consists of a rear part serving to hold in the grooves lm of the half-frames 1, the rear part of which positions it axially In relative to II, the part of the blade producing the musical sound when the trigger from the cam 6a is produced by the rotation of the roller 6, the front part 15c is used to give the note the desired frequency and may include a small damper 15d of residual resonances that at the top of the part 15c.
- the half-case 16 placed end to end constitutes a case which completely closes all of the components 1 to 15 and leaving only the winding rods 7 and the power take-off 9.
- These two half-cases 16 bring the resonance sought and the fixing means for the various possible applications, they slide on the sides lq from half-frames 1,1a and are welded or glued end to end according to II-II.
