ABSTRACT:
A cartridge shell for supporting a phonograph cartridge on the end of a tone arm is provided which is formed of a sheet of carbonaceous fibers bonded together by a synthetic resin into an L-shaped member having a horizontal leg portion and a vertical leg portion. A metal plate also of L-shape covers the upper surface of said horizontal leg of said carbonaceous fiber sheet and also covers the outer surface of said vertical leg of said carbonaceous fiber sheet. The metal plate intimately engages said fiber sheet and is firmly attached thereto. The cartridge shell is made light in weight with high internal loss and is also quite rigid. This is obtained by the use of the carbonaceous fibers bonded together by a synthetic resin and secured to a metal cover plate by a suitable adhesive or by a heat-press.
