  • cam gear member 24 is driven by the timing mechanism'of the clock through a suitable gearing arrangement so that it makes one revolution every twelve hours, and its position is indicated on the face of a clock by hour hand 36.
  • the principle portions of the structure so far described are illustrated and described in greater detail in US. Letters Patent No. 2,768,332, issued Oct. 23, 1956 to D. E. Protzmann et al. and assigned to the same assignee as the present invention.
  • SWITCH AND SWITCH MOUNTING ARRANGEMENT there is combined with the aforedescribed alarm clock elements a uniquely designed and positioned switch and switch-mounting arrangement 28.
  • the switch includes a pair of switch blades 38 and 40 having a pair of switch contacts 43 and 44 mounted at their upper ends.
  • the rearwardly extending shaft 30 of the cam gear member 24 normally abuts the end of switch actuator 32 to hold the switch blades in a spread-apart or open position.
  • the improved switch arrangement 28 includes a uniquely formed and positioned switch-mounting block 42 for holding the switch blades 38 and 40, and for inexpensively mounting the switch blades on the clock-supporting plate 6.
  • the unique switch block may be integrally molded of Noryl, nylon or other suitable material which may be provided with integral hinges 46 and 48 that can be folded without breaking the plastic.
  • the integrally formed switch block includes a generally flat central wall portion 50 and two generally flat sidewall portions 52and 54 for permitting the switch blades 38 and 40 to be conveniently gripped between the sidewall portions 52 and 54 and the central wall portion 50.
  • each of the switch blades 38 and 40 are provided notches 56 and 58 which are received by complementary studs 60 and 62 which are in tegrally formed with the sidewall portions 52 and 54 of the unique switch block.
  • the central wall portion 50 of the unique switch block is also provided with a notch 64 for receiving the projecting studs 60 and 62 in order to securely hold the switch blades on the switch block without permitting longitudinal movement of the blades.
  • stud 62 on wall 54 extends within the notch 58 of switch blade 40 and partially within the notch 64 in the central wall of the switch block, and stud 60 on wall 52 extends through notch 56 of switch blade 38 and partially within notch 64 formed in the central wall 50 of the switch block.
  • the switch blades are securely held on the switch block in spaced-apart relation and are prevented from longitudinal movement by the studs 60 and 62.
  • the formed inner walls 66 and 68, respectively, of wall portions 52 and 54 of the switch block prevent lateral movement of the switch blades 38 and 40.
  • My unique switch block is also provided with integrally formed means for holding the switch block 42 on the supporting plate 6 of the clock timer structure.
  • the mounting plate 6 of the clock is formed with two spaced-apart apertures 70 and 72 and the switch block is provided with apertures 74 and 76 formed at sidewall portions 52 and 54, respectively.
