SU11558A1 - Adjusting chromatic harmony to switch valves - Google Patents

Description

The proposed adaptation to chromatic harmony for switching valves serves the purpose of combining two well-known bahn-type harmonies in one instrument.

On the schematic Ch1gr; e fig. 1 shows a general view of the device; FIG. 2 is a section along the line OP in FIG. 1; FIG. 3- the same, along the line ABCEDEZZELM in FIG. one.

In housing 1, in a direction x 2 is placed 3, carrying two rows of metal arcs 4, 4 lying at their ends in bearings arranged on the transverse edges of frame 3; In addition, parallel to the rugs, there are two angular plates b, b, attached to frame 3 and carrying small rods 7 on themselves in terms of the number of remaining valves that are not connected to rod 5, 5; parallel to the arcs, there is a special arc 8 fixed in bearings 9 of housing 1 and always connected to the pins of 10 buttons I. The rods 5, 5 and 10 are their ends in plates 12 fixed in case 1. These plates, both on the one and the other side, they consist of three parts that can be disconnected (in the drawing there is no

indicated) along the line of rods 5 and 5. ,, with the two lower parts having a comb-like appearance, rods 5, 5 and 10 can be placed in their cuts, the upper rse part serves as a cover for rods 5 and 10, a movable wound 3 to one of its extreme positions pressed by the spring 13, to the other extreme position can be brought by the ruche through the projections 14 on the lid 15. The projections 14 are a continuation of the plastic 16, which one end rests in the direction. 17, at the other end, with its slot 18 lies on the pivoting lever 19, which serves to push the frame 3 3 to its extreme position.

The lever 19 can rotate in bearings 20, mounted in housing 1, and in 2K 1t by spring 21 to spring 22, which serves to hold in one of the extreme positions of frame 3. Protrusion 23 is arranged on lever 19, and in arc 8, respectively, protrusion 23-slot 33, which can skip this overhang. The valves 24 and 25 have pins 26, which touch one end of the pins, reinforced rods 5, 5, and the pins of the valves 25 are provided with lug-dots at the ends, according to the stroke of the frame 3,

and always pressed against the ends of the rods 7, Valves 24 and 25, as usual, are located on the axis of rotation 27 and are always pressed against the body, each with its own spring.

The mechanism is as follows: Suppose that frame 3 is in one of the extreme positions, namely in the lower one. By pressing button 11, we use rods 10 to deflect arcs 4, by the number of pins per rods x 10, in this case three arcs each, dragging three rods 5 behind them. The rods also have pins for connecting with arcs, as in pins 26 valves 24, JCOTOR and open. By pressing, for example, one button, we open three valves labeled "do-mi-salt" to obtain a "major major chord, and by pressing another button and open three valves labeled" l-to-mi to get a sober „l -minor chord. To switch buttons 11, i.e. so that one click of some other note is heard from pressing them: we move frame 3, with which the arcs 4, 4 and plates 6 move, b, the studs of the same rods 10 enter the saws of arcs 4 indicated by a dotted line in the drawing 28. Thus, said valves 24 are turned off, and other valves are turned on. In this case, the valve 24 with the inscription "F" is inserted into one button through the arc 4, because the kerf 28 of the arc 4 departs from the pin 31 indicated by a dotted line on the rod 10, and therefore the arc 4 is driven by this pin, and thus with a rod 5, a valve with the inscription "F" opens. Another button turns on a valve with an inscription „Re from among the valves 25, connected especially by rods 7, having a protrusion 30 on its lower side, which finds a pin 10 on the pin. The rods 7 with their front hangers should closely adjoin the plate 6, otherwise could move back and forth with their protrusions 30 to touch / for the pins of the rods 10 while moving the frame 3. In addition, the rod 7, which in this case is on the rod 10, should be located close to the latter. The end of the rod 7 should not go with the spatula pin 26 of the valve 25.

In all positions of the frame 3, the rods 10 with their pins casacrt arc 8 which serves as a fuse, so that at the time when one or several buttons are pressed, the frame 3 does not move and the mechanism would not be spoiled. This arc is always pressed against the pins of the 32 rods:; nd with 10 spring, not indicated on the drawing; thus, each pressing of the button deflects the arc 8, which stops the movement of the frame 3, even if by some circumstances we wished to transfer the frame 3 from one extreme position to another, because at the end of the arc 8 there is a slot 33, which finds on the protrusion 23 and thus prevents movement of the lever 19 connected to the plate 16 with the protrusions 14 for the arm. On the other hand, if the buttons are not pressed, you can transfer the 3 for the above purposes from one extreme position to the other as follows: with the thumb of your left hand, press the protrusion 14 of the plate 16, due to the movement of which in the guide 17, the other end deflects the lever 19 to the right side (while playing harmonica-down), and the end 29 of the arc 19 pushes frame 3 to the left. After reaching the leftmost position, the frame 3 is locked by a spring 22, which with its curved end extends into the slot of frame 3. During the reverse-pressing process 14 of the plate 16, the latter tilts the lever 19 in the opposite direction, and the end 19 of the lever 19 presses the spring 22, the end of which comes out of its nest, freeing frame 3, which is set in motion by iodine by the action of spring 13.

I Subject of the patent.

An adaptation to chromatic harmony for switching valves, characterized by the use of a frame 3 of arcs 4, 4 that are rotatably mounted in a harmony case that is movable in the case, for opening, with the leftmost position of the frame 3, valves 25 together with valves 24, or for opening, with right position, only clamps 24, for which purpose axially movable and controlled by buttons 11 rods 10 are provided with pins 31, acting
