  • Patent number: 6153029
    Abstract: A production of tapered bent tube wherein a U-cup with a full opening is pressed to form from a brass plate by a primary mold. The two ends of the full opening of the U-cup are of different calibers. The U-cup is subjected to tempering treatment to eliminate its processing stress. An assembly forming mold is used to punch the fill opening of the U-cup to form a rough shape of tapered bent tube with two different calibers at two ends, and between the two ends with different calibers is a flattened part. The flattened part on the tapered bent tube is removed to form a tapered bent tube; then, the seam of the tapered bent tube is welded and smoothed by roller pressing process, to complete the two ends of different calibers.

  • Patent number: 6143969
    Abstract: A mouth-pipe of a saxophone is disclosed. A mouth-pipe is covered on a top of a saxophone wind tube. A high pitch hole is installed on the upper end of the mouth-pipe which is pivotally installed with an octave key. A key cover is installed at the inner surface of the upper end of the octave key, and the key cover presses against the high pitch hole of the mouth-pipe. A ring is formed at the lower end of the octave key. A push rod connected to a high pitch key is installed above the saxophone wind tube. If the high pitch key does not press the high pitch hole, a high pitch is emitted; while if the high pitch key is released, a low pitch is emitted; Two long ear seats facing with one another are installed at the pivotal position of the octave key, and a convex point is formed at a lower end of each long ear seat. Two opposite long pivotal seats are placed at the pivotal positions of the mouth-pipe.

  • Patent number: 5898116
    Abstract: An improved plate assembly of woodwinds comprising a body being longitudinally provided with a plurality of tone holes is provided. Each of the tone holes is provided with a pair of posts at both sides. A copper shaft is pivotally mounted within the posts. A plate which may cover the tone hole is pivotally mounted onto the copper shaft. The lower portion of one of the posts is disposed with a resilient pin. The copper shaft is disposed with a projected pin shaft and a depressing key rod. The resilient pin is disposed such that the projected pin shaft is biased. When the depressing key rod is depressed, the copper shaft is rotated and the tone hole can be opened or closed by the plate to generate a special tone. The upper portion of the post is provided with a ball socket and both ends of the copper shaft are provided with a mounting hole respectively. One of the mounting hole of the pipe is provided with a groove.
