Patentiert im Deutschen Reiche vom 5. August 1905 ab.Patented in the German Empire on August 5, 1905.

Die Erfindung betrifft einen Blattwender mit pneumatisch auslösbaren Sperrteilen an einem den Wendearmen in ihrer Sperrstellung als Führung dienenden Gehäuse, bei welchem die Lagerung der Sperrteile derart getroffen ist, daß sie vom Auslösebalg auswechselweise, sonst aber auch gemeinsam aus dem Bereich der Wendearme entfernt werden können.The invention relates to a sheet turner with pneumatically releasable locking parts a housing serving as a guide for the turning arms in their locked position, in which the locking parts are mounted in this way What is taken is that they are replaced by the release bellows alternately, but otherwise also together can be removed from the area of the turning arms.

Oben auf dem Pulte ist eine Brücke 5At the top of the desk is a bridge 5

verschraubt. In der Mitte derselben ist eine Achse 6 fest aufgestellt, auf welche die Arme 7 zum Wenden des Blattes übereinander drehbar angeordnet sind. Schräg hinter der Achse 6 ist auf die nach hinten verlängerte Brücke ein zweiter, aber drehbarer Stift 8 aufgestellt. An jedem Arme ist eine Schraubenfeder 9 befestigt, deren anderes Ende an dem Stifte 8 angebracht ist (Fig. i, 2 und 3).screwed. In the middle of the same an axis 6 is fixed on which the Arms 7 are rotatably arranged one above the other for turning the sheet. Diagonally behind the axis 6 is to the rear extended bridge a second, but rotatable pin 8 is set up. On each arm A coil spring 9 is attached, the other end of which is attached to the pin 8 (Figs. I, 2 and 3).

Man ersieht, daß durch Drehen des Stiftes 8 die Schraubenfedern 9 gespannt werden und dieselben somit bestrebt sein werden, die Arme 7 von rechts nach links zu ziehen bezw. das mit denselben verbundene Blatt umzuwenden.It can be seen that the coil springs 9 are tensioned by turning the pin 8 and they will therefore strive to pull the arms 7 from right to left respectively to turn over the sheet connected to them.

Das Umdrehen des Stiftes 8 erfolgt an dem Griffe 10, nachdem durch Anheben der Stift 8 frei von der Brücke 5 gemacht ist.The turning of the pin 8 takes place on the handle 10 after lifting the Pin 8 is made free from bridge 5.

Das Zurückdrehen des Stiftes 8 wird durch ein Stiftchen 11 verhindert, welches in ein Loch der Brücke einschnappt und wird diese Verbindung durch die Schraubenfeder 12 gesichert (Fig. 1 und 3). Zur richtigen Führung sind die beiden Stifte 6 und 8 an der Oberkante durch eine Strebe 13 miteinander verbunden.The turning back of the pin 8 is prevented by a pin 11, which is in a The bridge snaps into the hole and this connection is secured by the helical spring 12 (Figures 1 and 3). For proper guidance, the two pins 6 and 8 are on the The upper edge is connected to one another by a strut 13.

Die Arme 7 sind alle derart gebogen, daß ihre Enden in derselben Ebene liegen (Fig. 1). Dieselben sind gabelförmig gebildet. Auf jedem Arme ist ein Gummiplättchen 14 vorgesehen, damit dieselben geräuschlos gegeneinander anliegen.The arms 7 are all bent in such a way that their ends lie in the same plane (Fig. 1). The same are fork-shaped. There is a rubber plate on each arm 14 provided so that the same rest noiselessly against each other.

Zur rechten Seite ist auf der Brücke 5 ein längliches Kästchen 15 befestigt, welches in die gabelförmige Aussparung der Arme paßt. In diesem Kästchen ist ein Riegel 16 scharnierartig angeordnet (Fig. 5). Das ausTo the right side, an elongated box 15 is attached to the bridge 5, which fits into the fork-shaped recess of the arms. In this box is a latch 16 arranged like a hinge (Fig. 5). The end

Claims

The end of the bolt protruding from the box is triangular in order to be able to be lifted through the lower part ij of the fork-shaped end of the arm on the one hand and to hold the arm in place on the other hand. The bolt 16 is pressed down by the helical spring 18.

Below the bolt, a plate 19 is also articulated, which through a coil spring 20 is pressed downward. On the front of the plate 19 a pin 21 is arranged, which protrudes through the lid of the box 15. Of the upper part 22 of the fork-shaped arm slides over the lid of the box. At the front of the box is a triangular plate 23 to guide the arms arranged. An air bag 24 (FIG. 5) is attached below the plate 19, in which a mouthpiece 25 opens. The air hose 26 is attached to this mouthpiece attached for the release of the arms of the sheet music turner.

The device is now made in such a way that by pressing on one at the end of the hose arranged rubber bag 27 (Fig. 3) of the air bag 24 is inflated and then first the plate 19 and then the bolt 16 is lifted. It will the pin 21 lay in front of an arm before the bolt 16 the one in front of this arm lets go of the lying arm so that only one arm is released from the latch at a time is turned over.

At the outermost end of each arm a plate 29 is arranged laterally displaceably in loops 28 (Fig. 6) and on this plate hangs in loops 30 vertically displaceable a clamp 32, pressed by helical springs 31 (Fig. 5) ', through which the sheet of music is gripped which is pasted with a strip of parchment paper for reinforcement in the upper right corner.

The rubber bag 27 is expediently placed under a third pedal, which next to the two other pedals located on the piano is arranged and through which the bag if necessary with the foot of the Player is squeezed. However, the bag can be placed at any other point on the piano and z. Belly by the knee or in some other way at the right moment, in which a sheet of music must be turned, be pressed together.

The mode of action is now as follows:

The music book 33 is placed on the bar 4 and this through the clamping bracket 3 so high that the right corners of the sheets comfortably fit into the Brackets 32 of the arms can be clamped.

Then all arms are moved to the right and set behind the bolt 16. Then the coil springs 9 are tensioned by turning the key 10. If you press Now while playing the rubber bag 27, the pin 21 is first in front the second arm raised so that it and behind it all following arms are held fast will. When the airbag 24 is inflated further, the plate 19 lies down down against the bolt 16 and lifts the same so high that the lower part 17 of the the former arm is released. The accompanying spring 9 then attracts the arm itself, whereby the sheet of music is folded over at the terminal 32.

This game is repeated every time the rubber bag 27 is pressed, until all the sheets are turned.

In the position of the arms on the left side they come against one with rubber to lie wrapped pin 34, which limits the stroke.

A simple push back to the right of all arms at the same time closes them again behind the bolt, by doing the lower parts 17 of the arms themselves the bolt to lift.

The connection that can be moved both horizontally and vertically the clamp 32 with the end of the arm ensures correct and faultless folding of the sheets, even if the music book is not should be exactly in the middle of the desk.
