Definitions

  • This invention relates to an elect-ro-magnetic talking-machine in which the sound is recorded and reproduced by means of a steel wire or band which is passed from one I spool to another through a ma net box.
  • the main object of the present invention is to provide means which allow the magnet box to be connected permanently to the mall chine, and the invention consists in this respect in forming the spool casing with an aperture through which the magnet box can enter and leave the casing when the latter is applied to and withdrawn from the machine.
  • Another object of the invention is to provide means for preventing displacement of the s 001s in the casing when the latter is withdi'awn from the machine, and in this 2 respect the invention consists in the provision of clutches arranged in the casing so as to engage the spools when the latter are disengaged from the driving spindles.
  • Fig. 1 of the accompanying drawings represents a side view of the machine, the spools and the enclosing casing being shown in section and in detached position.
  • Fig. 2 is a sectional view of one of the spools showing the clutch in the position it 85 occupies when the spool is attached to the driving mechanism, and
  • Fig. 4 is a plan of one of the clutch elements.
  • the record band or wire H is held by two spools A and B which are applied to the heads of spindles D for winding the hand from one spool to the other, the driving mechanism for the spindles being onclosed in a cabinet E.
  • the spools are onclosed in a casing composed of two drums C and an intermediate connecting arm M,
  • the casing being preferably composed of two shells which are pushed one into the other over the spools.
  • the magnets are enclosed in a box G which, according to the invention, is permanently mounted on the'cabinet E, the arm M being provided with slots F through which the box G is admitted when the casing and spools are applied .to the spindles D.
  • the liox G' is opene to admit the band or wire H.
  • Two clutch elements N and O are formed with crown teeth whereby they can be engaged to another.
  • the element N is fitted in the boss of the spool and the element 0 is connected to the casing above it.
  • a socket L secured to the casing serves as a guide for the element 0 and allows it to move in axial direction, a cross-pin K, which engages slots in the socket, preventing rotary displacement.
  • a coil spring I arranged about the socket L, bears against the clutch element 0 and tends to hold it in engagement with the element N, as shown in Fig. 3,,the spool being at the same time forced against the bottom of the casing so that dis lacement of the spool and a derangement o the wire in the casing will be prevented.
  • a spool casing record spools enclosed in said casing, driving spindles adapted to receive and to be coupled to said spools, and spring-pressed clutches engaging the spools in the casing so as to prevent normally a displacement of the same, the driving spindles being adapted to disengage said clutches automatically on entering the spools.
  • a spool casing record spools enclosed in said casin driving spindles adapted to receive an to be coupled to said spools, a clutch member semember on the spool and press the latter cured to each spool, a clutch member against the cas ng, the spindles being mounted within thecasingover each vspool a apted to'engage and displace the adjus- 10 so as to be ca able of axial but not'rotary table clutch members so as to release the 5 adjustment ative to the casing, and a spools when the latter are applied to the spring tending to hold said adjustable clutch machine together with the casing.
