La balan@oire representee au dessin com- prend un socle 1 surmonte dune charpente 2 ä laquelle est fix6e par un montant 3 une barre d'articulation 4 maintenue en Position horizontale. Un levier oscillant de commande 5 est articu16 ä 1'extr6mite Bauche 40, en regar- dant la fig. 1, de la barre 4. Ce levier de commande 5 est "recourbe detix fois ä angle droit en 6 et 7 (fig. 3), et sa Partie inferieure est calee sur un tourillon 8 pouvant tourner dann un palier 9 fixe dans uue Platine lourde 10. Cette Platine Porte deux autres paliers 11 et 12 dans lesquels peut tourner 1'arbre 1.3 qui Porte un tambour 14 uruni de goupilles 15 destinees ä cooperer avec une serie de lames sonores 16 pour constituer un mouve- ment *de musique. The swing represented in the drawing comprises a base 1 surmounted by a frame 2 to which is fixed by an upright 3 a hinge bar 4 maintained in a horizontal position. An oscillating control lever 5 is hinged to the Bauche end 40, looking at FIG. 1, of the bar 4. This control lever 5 is "bent ten times at right angles at 6 and 7 (fig. 3), and its lower part is wedged on a journal 8 which can rotate in a bearing 9 fixed in a Platinum heavy 10. This turntable carries two other bearings 11 and 12 in which the shaft 1.3 can rotate which carries a drum 14 fitted with pins 15 intended to cooperate with a series of sound blades 16 to constitute a movement *music.

Le tourillon 8 constitue Faxe d'oscillation du levier de commande 5-6-7. Au-dessus du tourillon 8, 1e levier de commande est relie par une bielle 18 ä une manivelle 19 montee sur un prolongement de Farbre 13. Au-dessous du tourillon 8, 1e levier de commande 5 est reli6 par une seconde bielle 20,ä une mani- velle 21 mont6e egalement sur 1e prolonge- ment de Farbre 13. La manivelle 19 est sou- dAe ä un manchon 23 entourant librement Farbre 13 et presentant une ferste axiale 24 dans laquelle est engagee 1'extremite 25 d'un- ressort helicoidal 26 enroide ä frottement doux sur 1'arbre 13. Le manchon 23 et 1e ressort 26, en coop6ration avec la ferste 24, constituent des organes transmetteurs de couple ä sens unique. Pin 8 constitutes the axis of oscillation of control lever 5-6-7. Above the pin 8, the first control lever is connected by a connecting rod 18 to a crank 19 mounted on an extension of the shaft 13. Below the pin 8, the first control lever 5 is connected by a second connecting rod 20, a crank 21 also mounted on the extension of the shaft 13. The crank 19 is welded to a sleeve 23 freely surrounding the shaft 13 and having an axial ferste 24 in which the end 25 of a spring is engaged. helical 26 fits smoothly on shaft 13. Sleeve 23 and spring 26, in cooperation with spring 24, constitute one-way torque transmitting members.

Dune fa@on analogue, la manivelle 21 est soudee ä un manchon 29 dann une ferste axiale 30 duquel est engagee une- extremite 31 d'un ressort helicoidal 32. A Poppose des mani- velles 19 et 21, Parbre 13 presente un touril.- lon 35 Sur lequel tourne un lavier oscillant 36 presenta-nt deux coudes ä angle droit 37 et 38 et relid par son extremite superieure ä un axe d'articulation 41 de la Barre 4. Cette Barre est parallele au plan ddtermind par faxe geometrique du tourillon 8 et celui de Parbre 13. L'ensemble des organes 4, 5, 8, 13 et 36 forme un parallelogramme articide. Similarly, the crank 21 is welded to a sleeve 29 in an axial ferst 30 of which is engaged an end 31 of a coil spring 32. Opposite the cranks 19 and 21, the shaft 13 has a turret. - lon 35 on which rotates an oscillating lever 36 presented two bends at right angles 37 and 38 and connected by its upper end to a hinge pin 41 of the bar 4. This bar is parallel to the plane determined by geometric fax of the trunnion 8 and that of Parbre 13. All the bodies 4, 5, 8, 13 and 36 form an articidal parallelogram.

La platine lourde 10 est fixee au fond dune nacelle 42 constituant la partie mobile de 1a balangoime. The heavy plate 10 is fixed to the bottom of a nacelle 42 constituting the mobile part of the balangoime.

Si 1'on Fait osciller la balan@oire 42 pre- miArement suivant la flache F1 autour des axes 40 et 41, 1e lavier de commande 5 oscille dans 1e sens F, autour du tourillon 8 (fig. 2). La bielle 18 entraine alors la manivelle 19 dann 1e meme sens de rotation, et 1e manchon 23 tend alors ä desserrer las spires du ressort hdlicoidal 26, de Sorte que la manivelle 19 tourne (olle autour de Parbre 13. La bielle 20 Fait tourner la manivelle 21 dans 1e sens F3 autour de laxe geometrique de t'arbre 13. Dans ces conditions, 1e manchon 29, en resser- rant las spires du ressort 32 Sur Parbre 13, entra1ne ce dernier dans 1e sens de la flache F3. Le tambour 14 tourne dans 1e meme sens et las goupilles 15 font vibrer las lames 16 de maniere ä jouer une partie du morceau de musique materialise par ces goupilles. If the balance 42 is oscillated first along the wane F1 around the axes 40 and 41, the first control lever 5 oscillates in the first direction F, around the trunnion 8 (FIG. 2). The connecting rod 18 then drives the crank 19 in the same direction of rotation, and the sleeve 23 then tends to loosen the coils of the hydraulic spring 26, so that the crank 19 rotates around the shaft 13. The connecting rod 20 rotates the crank 21 in the first direction F3 around the geometric axis of the shaft 13. Under these conditions, the first sleeve 29, by tightening the coils of the spring 32 on the shaft 13, drives the latter in the first direction of the wane F3. 14 rotates in the same direction and the pins 15 cause the blades 16 to vibrate so as to play part of the piece of music materialized by these pins.

Lors de la demi-oseillation suivante qui s'effectue dans 1e sens de la flache F4 (fig. 1), le lavier de commande 5 tourne dann 1e sens de la flache F5 (fig. 2) autour du tourillon 8, de Sorte que c'est alors la manivelle 19 qui tourne dans 1e sens de la flache F3 autour de faxe de Parbre 13. Daus ces conditions, le manchon 23, en resserrant las spires du res sort 26 Sur Parbre 13, entraine ce dernier en rotation dans 1e meme sens que pr6c6dem- ment, c'est-ä.-dire suivant la flache F3. Le manchon 29 tournant alors Jans 1e sens con- traire des aiguilles dune montre (fig. 2), las spires du ressort 32 se desserrent quelque peu et la manivelle 21 tourne alors folle Sur Parbre 13. Pour chaque demi-oscillation du lavier de commande 5 et de la balan@oire 42, Farbre 13 et 1e tambour 14 tournent done dans un sein sens qui est celui de la flache F3. During the following half-osillation which takes place in the first direction of the wane F4 (fig. 1), the control lever 5 rotates in the 1st direction of the wane F5 (fig. 2) around the trunnion 8, so that it is then the crank 19 which turns in the first direction of the wane F3 around the axis of the shaft 13. Under these conditions, the sleeve 23, by tightening the turns of the spring 26 on the shaft 13, causes the latter to rotate in the first same direction as before, that is to say along the wane F3. The sleeve 29 then turning in the first direction counter-clockwise (fig. 2), the coils of the spring 32 loosen somewhat and the crank 21 then turns freely on the shaft 13. For each half-oscillation of the control lever 5 and the balan@oire 42, the shaft 13 and the first drum 14 therefore rotate in one direction which is that of the wane F3.

Gräce ä Fabsence de cliquets dans las or- ganes transmetteurs de couple, 1e dispositif ddcrit fonetionne sans- bruit. Thanks to the absence of pawls in the torque transmitting members, the device described operates without noise.
