Definitions

  • the present invention relates to mountings for telephone hand sets and more particularly to a desk mounting specifically adapted for use in supporting the elements of a telephone substation on either side of a desk or table, or on a wall.
  • These elements may conventionally comprise a dial mechanism, a signal device or bell, the usual induction coil and condensers, a telephone hand set of the well-known monophone type, and switching mechanism including a switchhook which forms the supporting element for the hand set.
  • the mounting comprises a housing having an open end, a plate for covering the open end of the housing and a pedestal adapted to be mounted on the cover plate and upon which the dial mechanism is supported.
  • the signal device, induction coil, condensers, and switching apparatus are all supported within the housing on a member extending longitudinally thereof and secured to the cover plate and the bottom of the housing.
  • the switchhook extends through a side of the housing and is arranged to extend outward from the front of a desk upon which the mounting is supported. Means are provided such that either one of three sides of the housing may be secured to a supporting structure.
  • the elements of the mounting are so arranged that the mounting may be mounted at either end of a desk, for example, and, irrespective of the end of the desk upon which the mounting is sup-ported, the finger wheel of the dial mechanism faces toward the position a person sitting at the desk would normally occupy.
  • no relative movement between the housing and the dial supporting pedestal is necessary to adapt the mounting for support at either end of the desk, the required change in position of the finger wheel being obtained by rotating the housing through substantially a right angle about its longitudinal axis.
  • means are provided whereby the supporting member may be supported in either of two positions within the housing.
  • the dial mechanism supporting pedestal is so arranged that it may be mounted in either of two positions on the cover plate.

  • the position of the pedestal 26 relative to the cover plate II is changed by utilizing the tapped drill holes 40 for attaching the pedestal 26 to the plate II.
  • the strap 45 is mounted on the side of the housing I9 opposite that utilized in the support of the mounting as shown in Fig; 6.
  • the strap 45 is attached to the lower side, as shown in Fig. 6, of the housing II This corresponds to a ninety degree clockwise rotation of the housing from the position shown in Fig. 6, and orients the finger wheel 21 in a position facing the normal position of a person sitting at the desk without relative movement between the pedestal 26 and the housing 10.
