Definitions

  • This invention relates to musical instruments, such as Saxophones, comprising spatulate keys, stops, caps or other finger pieces arranged adjacent one another and moved by the fingers of the musician.
  • the invention obviates this disadvantage by eliminating the need for a safety margin.
  • the musician need only raise his finger to the height required to overcome the difference in level between the spatulate keys.
  • an entraining member is fixed to the tab at a distance from the hinge. When the otherspatulate key is depressed, this member is entrained with it.
  • the tab entrains the tab downwards.
  • the tab' tilts from the hinge, which remains at the same level as the spatulate'key, down towards the lowered zone, for example the aforementioned contact point, to which the entraining'membere is fixed.
  • this member extends from that surface of the spatulate key opposite its contact surface so as to keep this contact surface clear.
  • Support can be provided by a knob which projects from the tab and which engages in a supporting fork or cavity provided on the other spatulate key.
  • This knob also acts as entraining member in conjunction with the upper surface of the cavity.
  • the combined entraining and supporting members In order to render compatible the various pivoting movements of the tab and spatulate keys about their various respective axes, it is advisable for the combined entraining and supporting members to cooperate with some play, advantageously in two perpendicular directions.
  • the engaging end of the supporting or entraining knob can be conical in shape and/or the fork can be widened to facilitate movement of the knob in the fork.
  • FIGS. 5 and 6 are sections through another two em- A spatulate key 5 is fixed to the end of a lever 6 integral with the rod 1'. Another spatulate key 7 is fixed to the end of a lever 8 integral with the rod 2.
  • the spatulate key 5 is oblong. It comprises a plate 10 and a tab 11. The lower surface of the plate 10, opposite its contact surface 9, is fixed to the lever 6.
  • the tab 11 is pivotally connected to one edge of the plate 10 through a conventional pivotal joint or hinge 12.
  • the hinge consists of a central male knuckle of the tab arranged between two female knuckles of the plate.
  • a pin 13 is inserted into the eyes of the knuckles.
  • One edge 14 of the tab 11 is opposite an edge 15 of the other spatulate key 7.
  • the pin 13 forms with the edges 14 and 15 an acute angle a.
  • a free edge 16 of the tab 11 is adjacent the edge 14.
  • the tip or corner of the tab 11 defined by the edges 14 and 16 is more remote from the pin 13 than the rest of the tab 11.
  • a tongue, bent in the form of an L extends from the lower surface of this corner.
  • the end arm 17 of the tongue and the lower surface of the corner form the two arms of the fork. From its beginning toward its end, the arm'l7 diverges from the lower surface of the tab 11, although the fork is widened.
  • the part'located between the two arm of the fork is turned with respect to the edge 16, whilst the lateral opening of the fork opens below the edge 14.
  • a tongue 18,-extended by a tapering knob 19, extends from the lever 8 of the other spatulate key 7.
  • the knob 19 projects from the edge 15 and is engaged in the fork through the lateral opening thereof.
  • FIG. 2 the two spatulate keys 5 and 7 are shown in their rest position.
  • FIG. 3 pressure has been applied to the plate 10 of the spatulate key 5.
  • the knob 19 integral with the other spatulate key 7 has remained fixed and has formed a supporting member for the lower contact surface of the tip of the tab 11 referred to above. Entrained by the plate 10, the tab 11 has pivoted about theh knob 19. It forms a ramp leading from the hinge l2, situated at the same level as the spatulate key 5, to the tip situated at the same level as the other spatulate key 7.
  • the movement of the knob 19 in the fork in two perpendicular directions, and more especially the taper of the knob 19, enables the spatulate key 5 and the tab 11 to pivot about different axes.
  • FIG. 5 illustrates another embodiment.
  • the supporting and entraining knob 19 is integral with the spatulate key 5, whilst its receiving member, which supports or entrains it, is arranged on the other spatulate key 7.
  • this member is in the form of a recessed cavity 20 whose opening is larger than the cross-section of the knob, thus enabling the knob to move in the cavity.
  • the knob and the fork are interchangeable in regard to their positions, in other words the knob can be positioned under the tab 11 of the spatulate key 5, and the fork under the spatulate key 7, as shown in FIG. 6, or the knob can be positioned under the spatulate key 7 and the fork under the tab 11 of the spatulate key 5.
  • a spatulate key comprising a plate, a tab, means pivotally connecting the tab to the plate with one edge of said tab adjacent the plate and parallel to the pivot axis, and an entraining member fixed to the tab at a predetermined distance from the pivotal connection.
  • a musical instrument such as a saxophone, comprising first and second spatulate keys, wherein the first spatulate key has an edge adjacent the second spatulate key and comprises a plate, a tab, means pivotally connecting the tab to the plate with one edge of said tab adjacent the plate and parallel to the pivot axis and an extraining member, and the second spatulate key comprises an associated supporting member cooperating with the entraining member with a degree of play the aforementioned associated members being movable in mutually perpendicular directions.
  • the supporting member has a part defining a cavity for receiving a knob carried by the entraining member and adapted to engage in said cavity, the engaging end of the knob being conical.
  • a musical instrument as claimed in claim 7, comprising levers integralwith rods for operating the spatulate keys, wherein the pivotal connecting means sof the first spatulate key forms, with the edge of the tab adjacent the second spatulate key, an acute angle.
