As heretofore constructed, the tubing of brass musical instruments such as comets, trumpets, etc., are hard soldered or brazed directly to the valve casings or chambers. This process of hard soldering or brazing requires the application of relatively intense heat which softens or anneals the metal of the valve casing or chamber more especially in the region thereof to which the heat is applied. Due to the softening of the walls of the valve casings the inner surfaces thereof which are engaged by the valves wear unevenly and said casings must be replaced after a relatively short time. Also, such heat frequently warps the valve casings. One object of the present invention, therefore, is to obviate these objections and disadvantages and for that purpose to provide for connecting the tubing to the valve casings in such manner that the hardness of the casings is conserved thereby increasing the life of the casings and improving the operation of the valves therein...
