Abstract

190,759. Sykes, A. F. Aug. 29, 1921. Addition to 160,223. Magnetic instruments.-Consists in the use in sound-recording apparatus of the kind claimed in the parent Specification, of an electromagnetic recording device having an armature of the reed or bar type, which armature is provided with stiffening fins or the equivalent, and has the engraving stylus directly attached thereto. Damping material, such as rubber, may be interposed between the armature and the stiffener, and, further, oil or other viscous liquid may be interposed between the magnet-poles and the armature. Figs. I and II (22860/21) show a construction in which the reed armature 120 of a Brown telephone receiver has attached thereto, or integral therewith, a stiffening extension 121, to which an engraving jewel 3 is secured. The magnet and windings are immersed in grease or the like, to suppress parasitic vibrations. The harmonics of the recorded sounds may be magnified by associating the recorder with compensating circuits in various ways. In the modification shown in Fig. III (22860/21), which is designed for making lateral-cut records, the stiffened armature 120 is mounted on a traversible block 122, so that the air-gap between the armature and the poles may be adjusted. The magnet may be duplicated and arranged so as to act differentially on the armature. The device shown in Fig. I (31027/21) comprises a Brown receiver, to the armature 120 of which is attached by a screw 132 a metal sheet 129, having soldered thereto a stiffener 130 which carries the stylus 3. A rubber pad 128 is inserted between the parts 120, 129. The screw may be omitted and the other parts cemented together. Fig. II (31027/21) shows a further modification. The armature 62 is attached to a lamina 133 which carries the stylus and which is pierced near one or both ends to form a number of resilient strips 134, the. apertures being preferably filled in with rubber. A slotted holder, to which the member 133 is clamped at its ends, carries a ball to determine the depth of cut in the wax. The holder is attached to the shell of the receiver. Specification 190,840 is referred to.
