1This action is in every way similar to that employed in the cornet made by Ch. Sax, of Brussels, and previously described (No. 381).
32. A model of an action frequently employed in the early days of valve instruments; there are three pistons, the arrangement of the air-passages and extra tubing being similar to that described under No. 388.
53. A model of the early French action described under No. 398.
74. A model of an action designed by Adolphe Sax. The pistons are unusually thick, and, for the size of the bore, very heavy. The diameter of the bore is only .38 inch. The passages for the open notes run straight through the centre of the valves. When the valve is depressed, the passages bringing the extra tubing into connection are disposed at right angles to the main windway.
95. A model of the system called "Besson's Clear Bore." This action was patented in France in 1855 by Gustav Besson, and it was virtually an improvement upon that of Perinet. Previous to this the passage of the second valve presented an angularity, and consequently the notes produced by the combination of 1 + 2, or 2 + 3, or 1 + 2 + 3 valves were of bad quality. The pistons in this action preserved the same sectional area of the wind column throughout, and allowed a bullet, fitting the bore exactly, to pass through, in whatever position the valves might be. Eight pistons of different kinds were included in the patent, and they could be assembled in 512 different ways! And M. Besson's second valve could be used with first and third pistons of the Perinet or Rödel design.
11The engraving, a facsimile of that in the French specification, represents the usual form of the action as first made, the springs being placed below the pumps. The specification itself should be consulted for further detail.
136. A sectional model of the "Courtois" action, made by Henry Distin.
157. A sectional model of the "Patent Light Valve" invented by Henry Distin. This "light" valve is largely used now by various
