Definitions

  • the invention relates to a kit of a mechanical reset aid for the keyboard of mechanical keyboard instruments, in particular organs, with an arrangement for switching this reset aid on and off.
  • Organs of the type mentioned according to the preamble have so-called wind chests for the purpose of sound generation, on which the labial or reed pipes sit and air flows through according to the organist's keyboard play, which is done by means of a mechanical action.
  • the button is connected to the valves that block or release the air supply via a bridge and, if necessary, cable, wire or wooden cables.
  • An organ can have between a few hundred and several thousand pipes.
  • the organist sits at the game table, which is arranged directly or at a distance from the pipe construction.
  • This game table usually has several manuals and a foot pedal row.
  • Each manual is assigned a predetermined number of registers depending on the size of the organ.
  • the tones of the organ sound when one or more registers are open, thereby allowing air to enter the row of pipes belonging to the register.
  • the organist can couple several, usually two or three manuals together, so that all tones of all manuals are heard. He can also put together different registers so that he gets a mix of tones, etc.
  • the organist can control the valves which are responsible for responding to the pipes almost synchronously with the key press; he can thus optimize the response speed depending on the expression dynamic of the interpretation.
  • This "Barker lever” enables almost synchronous control of the sound valves in the wind chest like a purely mechanical action.
  • the invention is therefore based on the object of creating a kit according to the preamble which allows, in a free-standing game table, where there are abstract lengths of several meters between a button and a game valve in the wind chest or wave board So-called “Barker system” is integrated or can be used to use this kit so that the spring force on which the "Barker lever” is based can be disregarded and optionally activate or deactivate this kit for the reset aid.
  • the kit consists of a lever joint and control cams which can be activated via the working path of a pneumatically operated working bellows integrated in a housing and via the closing and opening movement of check valves, and here that Lever joint has a pull bringing the keyboard into the starting position and below the working bellows there is a control cam connected to the valve, which can be adjusted by this and through the lever joint, a valve connected to the keyboard being connected to the valve, which can be activated and having a Pull arm engaging lever is arranged.
  • the lever joint consists of an actuating rod arranged approximately at right angles on the working bellows, bearing block, spring support, spring and spring lever with adjusting cams and an angle lever with stop head mounted on a bellows stroke limitation.
  • a preferred embodiment of the invention provides that the adjusting rod located on the bellows is designed to be height-adjustable, and the entire system can be adjusted to the desired sensitivity in combination with all adjustment and adjustment options.
  • the arrangement of the lever joint makes use of the lifting movement of the working bellows.
  • the axis of the control rod runs through the support surface of the angle lever, the bellows stroke limitation, which carries a bearing block for receiving the angle lever, is U-shaped and with its downwardly projecting legs is arranged on the air flow channel provided below the beam in such a way that between a free space is formed in the crosspiece of the bellows stroke limitation and the surface of the bellows, in which the bellows can move freely.
  • the angle lever is in this case rotatably mounted about the axis of the bearing block and is arranged with its lever part, which has the bearing surface, projecting into the bellows stroke region above the head region of the adjusting rod.
  • the stop head is adjustable or rotatable. In a special embodiment of the invention, this can be done by means of a threaded rod.
  • a return spring is provided between the inner surface of the spring support and the inner surface of the spring lever.
  • the bearing block resting on the surface of the bellows has a protruding spring support and, in the area of the bearing block part projecting beyond the end face of the bellows, has a recess penetrated by the spring lever. Furthermore, the bearing block provides a bore or the like for the passage of the train connected to the key.
  • the adjusting cam of the spring lever is conical, the larger base being arranged pointing towards the spring lever and in this case merging into a cylinder body with a smaller cross section, so that an engagement area for the control cam is formed.
  • the adjustment cam is designed to be adjustable.
  • the control cam is axially fixed below the bellows by means of an axis of rotation and is connected to the shut-off valve via a train, this train leading to an axis point of the control cam and following a circular path around the axis of the axial fixation when the valve moves.
  • the control cam has a nose which can be protruded into the engagement area of the adjusting cam.
  • the arrangement for switching the kit according to the invention on and off is characterized by a lever which is rotatably mounted in a height-adjustable mounting bar.
  • the pull arm is mounted as a one-armed lever below the housing and with the lever connected variable distance by a train.
  • a lever area of the lever engages in the engagement area of an angle lever for activating a check valve when the position is activated, the angle lever being rotatably mounted below the housing.
  • This consists of a lever joint 6 and control cams 7 which can be activated via the working path of a pneumatically operated working bellows 3 integrated in a housing 2 and via the closing and opening movement of blocking valves 4, 5 and control cams 7.
  • An adjusting rod 12 is arranged on the working bellows 3. Whose axis 21 leads through the support area 22 of an angle lever 19, so that the head area 33 of the actuating rod 12 comes into contact with the support surface 22.
  • the lever joint 6 is placed on a bearing block 29 and rotatable about the axis 30.
  • the bearing block 29 itself is arranged on a bellows stroke limiter 18.
  • the lever joint 6 consists of an angle lever 19 with a lever part 31 which protrudes into the bellows stroke area 32 via the head area 33 of the actuating rod 12.
  • the other lever part 37 of the angle lever 19 has a stop head 20, the axis 34 of which extends through the engagement region 35 of a spring lever 16.
  • the bellows stroke limiter 18 is preferably U-shaped and has two legs 23 and 24 projecting downwards, between which the bellows 3 is passed. The legs 23 and 24 are fastened to the air flow channel 25 and have no connection to the bellows 3.
  • the cross bar 26 of the bellows stroke limiter 18 serves here as the uppermost limit for the movement of the bellows 3, with a space 28 between the cross bar 26 and the surface 27 of the bellows 3 is formed, which is preferably filled with a felt or the like not described here, so that damping is achieved.
  • a bearing block 13 is arranged on the bellows 3 and has a spring support 14 and a spring lever 16.
  • a spring 15 is positioned between the inner surfaces 40 and 41 of the spring support 14 and the spring lever 16.
  • the angle lever 19 has a lever part 37 with a stop head 20, the axis 34 of which extends through the engagement region 35 of the spring lever 16.
  • the stop head 20 is adjustable or rotatable for the purpose of varying the distance between the lever part 37 and the spring lever 16. This can e.g. B. by an internal thread for engaging a threaded rod forming the axis 34.
  • the bearing block 13 which is placed on the bellows 3, protrudes beyond the end face 42 of the bellows 3, a recess 44 penetrated by the spring lever 16 being provided in the bearing block 43.
  • an axis of rotation 45 running perpendicular to the spring lever 16 is provided in the bearing block 13.
  • the bearing block 13 has a bore or the like.
  • the spring lever 16 has an adjusting cam 17 at the bottom end, which is preferably conical.
  • the larger base area 47 of the adjusting cam 17 points towards the spring lever 16 and merges into a cylinder body 48 with a smaller cross section, so that an engagement region 49 is formed.
  • This setting cam 17 is also adjustable by means of a threaded rod 50.
  • the control cam 7 is axially fixed below the bellows 3 by means of an axis of rotation 51 and is connected to the shut-off valve 4 via a train 62, the train 62 leading in an axis point 53 of the control cam 7 and this orbiting around the circular path 54 when the valve 4 is mastered the axis 51 treads.
  • the control cam 7 has a nose 55 which can be inserted into the engagement region 49 of the adjusting cam 17.
  • the lever 9 is rotatably mounted in a height-adjustable receiving bar 56.
  • the pull arm 10 is designed as a one-armed lever and is mounted below the housing 2 and connected to the lever 9 by the pull 8 with variable distances.
  • the lever area 57 of the lever 9 projects into the engagement area 48 of the Angled lever 59, wherein the valve 4/5 is activated, the angled lever 59 being rotatably mounted below the housing.
  • FIG. 1 shows the kit 1 according to the invention. It essentially consists of a lever joint 6, control cams 7 and a lever 9 which can be brought into the engagement and disengagement position.
  • the kit is integrated in a housing 2.
  • the bellows 3, air flow channel 25 and the check valves 4 and 5 with return spring 60 form the "Barker lever" known per se.
  • the keyboard 11 (not shown) is actuated, the lever 9 is pulled downward by the stop 61, the train 8 transmitting this tensile force to the windchest and thus z.
  • B. actuated a tail valve (not shown) to release the air into the pipe (not shown).
  • the pressure to be exerted on the keys 11 and the key restoring force are correspondingly high, so that the organist's key play is impaired. This disadvantage is significantly improved by using the so-called "Barker lever".
  • the spring 60 must be of a correspondingly strong design so that the key returns quickly enough and thus a good repetition is achieved.
  • pressing the button on the gaming table then increases in accordance with this spring force, so that the play of the organist is negatively influenced.
  • the invention provides that on the bellows 3 a Lever joint 6 activatable control rod 12 and a spring lever 16 fastened to a bearing block 13 are arranged, which, in interaction with a control cam 7 arranged below the bellows 3, uses the lifting work of the bellows to reset the keyboard.
  • an actuating rod 12 is provided on the working bellows 3 belonging to the "Barker lever", which moves with the working bellows 3 to the lifting movement.
  • the bellows 3 itself sits on an air flow channel 25, the working bellows being inflated due to the closed pressure system when the valve 4 is open and the valve 5 is closed, as shown in FIG. 1.
  • the angle lever 59 When pulling the valve, i.e. by pressing the keys 11, the angle lever 59 is rotated about its axis 63 and pulls, since this is fastened to the train 62 by means of the locking screw 64, the valve 5 loaded by the spring 60 in the release position and the bellows 3 collapse.
  • the bellows 3 is inflated again.
  • the kit 1 according to the invention is used.
  • the button is released, that is to say during the inflation movement of the bellows 3, the spring lever 16 is carried upward. This happens because it is attached to the bearing block 13 by means of an axis of rotation 45 and the bearing block 13 itself rests on the surface 27 of the bellows 3.
  • the setting cam 17 engages with its engagement area 49 under the nose 55 of the control cam 7 and thereby pulls the abstracts (not shown) or the buttons back, so that the tone speaks quickly and a correspondingly good repetition is ensured.
  • control cam 7 and the setting cam 17 are separated from one another by the rocker arm 19, activated via the setting rod 12, pressing against the spring lever 16 and thus pulling the setting cam 17 out of the nose 55 of the control cam 7. This is important since the control cam 7 must move freely when the button 11 is depressed again.
  • Depressing the button 11 depresses the lever 9 or rotates it about the axis point 65.
  • the keyboard 11 is connected to the lever 9 by means of a train 66, a stop screw 61 being in direct contact with the lever 9 and carrying it downward in accordance with the train movement.
  • the lever part 57 of the lever 9 engages in the area 58 of the angle lever 59, which is rotatably mounted about an axis 63 of a bearing block 68 below the housing 2.
  • the angled region 69 of the angle lever 59 is connected to the valve 5 and 4 by means of a train 62 and locked by means of the adjusting screw 64.
  • the action of the lever 9 on the angle lever 59 brings the valve 5 into the release position, the force of the spring 60, which is countered by the stop 70, to be overcome.
  • the bellows 3 collapses, so that no more force acts on the angle lever 19 via the actuating rod 12.
  • the control cam 7 is activated.
  • This is arranged below the bellows 3, preferably rotatable about an axis 51 by means of a bearing block 71, the train 62 which travels with the valve 4 and 5 being guided into an axis point 53 of the cam 7 and thus rotating it about the axis 51.
  • the axis point 53 here follows a circular path 54 around the axis point 51, the valve 4 and the train 62, as shown schematically in FIG. 5, making a slight upward movement. However, this can be ignored due to the sealing elements on the valves.
  • the nose 55 of the control cam 7 can move freely here, since the setting cam 17 is out of engagement with the control cam 7 at this time, as will be described later.
  • the downward stroke movement of the bellows 3 has no effect on the angle lever 19, since this rests on the axle 30 on the bellows stroke limitation 18, which is not connected to the bellows 3, i.e. via the bearing block 29. is not connected to the lifting movement of the bellows 3.
  • the bellows 3 When the button is released again, the bellows 3 is inflated.
  • the spring lever 16 is carried upwards and pulls the abstracts (not shown) or the keys 11 back, the adjusting cam 17 remaining in engagement under the nose 55 of the control cam 7.
  • the spring lever 16 Shortly before the bellows 3 has reached the uppermost position, the spring lever 16 is moved against the spring carrier 14 by activating the angle lever 19, which now moves with its stop head 20 with a circular path 72 around the axis 30, the adjusting cam 17 moving the circular path 73 around the Axis 45 treads and comes out of engagement with the nose 55 of the cam 7.
  • the lever 9 is rotatably mounted on a receiving bar 56 in the axis 65.
  • the bar 56 accommodates a plurality of levers 9, corresponding to the number of buttons.
  • the receiving bar 56 does not require a connection to the housing 2 and is designed to be vertically movable as a whole, ie the receiving bar 56 is, for. B.
  • lever 9 frontally mounted and movable in height by means of a lever or swivel mechanism, so that the lever 9 is pivoted about the theoretical point 74 and in this case follows a circular path 75, so that a distance between the lever part 57 and lever part 58 of the lever 59 arises, the no more engagement of the lever 9 in the lever 59 is permitted and the lever 9 rests on the stop 76, which practically forms the end of the train 8.
  • the lever 10 is activated via the stops 76 and 77, the lever 10 being rotatably arranged below the housing 2 in an axis 78.
  • the kit according to the invention is to be assigned to each manual for which a Barker system is desired, i.e. e.g. B. in a manual with 58 keys, e.g. B. C to a '' '58 kits are arranged in several levels one above the other, each offset by a manual division or key division.
