Abstract

239,893. Wolinski, M. I. March 24, 1924. Securing tools to arms.-A device for holding a number of gramophone needles, adapted to be secured to or take the place of the usual needlesocket of a sound-box and capable of being turned to bring any one of the needles into position for playing, is so constructed that the needles are parallel to one another when clamped within the holder. The device shown comprises a cylinder a, closed at one end, and provided with a bush b and a headed pin e, the head f being pressed down by a spring g; the stem of the pin e, which is adapted to fit into the needle-socket of the sound-box, protrudes through a hole in the end of the cylinder. A group of needles h is secured in the holder, being wedged by the pointed end of a screw d. When one needle has been used, another is brought into the proper position for playing by rotating the casing a, together with the group of needles, about the pin e, different coloured indentations being provided on the out. side of the, casing, as indicators. The device may be permanently fitted to a sound-box.
