Abstract

328,039. Dieux, J. Jan. 17, 1929. Pick-ups, supporting in machines.-An electric pick-up or like device is carried by two pivoted arms which are crossed intermediate their connection respectively with the pick-up and a pivotal support for the arms. The arrangement is such that the pick-up tends to maintain a constant angle with the direction of the record grooves. The carrier arms consist of two bars 1<1>, 12 hinged at their ends 2<1>, 2<2> to two lugs 3<1>, 3<2> cast on the boss 4. This boss 4 is itself threaded on a spindle 5 fixed on a supporting cap 6 and can thus rotate about the vertical axis P. The bars 1<1>, 1<2> are united at their other ends by swivel joints 7<1>, 7<2> with the casing 8 of the pick-up device. The bar 1<2> has a slotted central part 12 to allow free displacement of the bars with respect to each other. The boss 4 may be made eccentric with respect to the axis P.
