Definitions

  • FIGURE 1 is a simplified perspective View of the pertinent portion of an alarm clock mechanism embodying the present invention, with the alarm set and triggered to respond;
  • FIG. 2 is a side elevation of a clock employing the mechanism of FIG. 1 in the set condition;
  • FIG. 3 is a back view of the clock mechanism with portions broken away to showthe profile of the shut-off slide;
  • FIG. 4 is a fragmentary top view looking along the line 4-4 of FIG. 3;
  • FIG. 5 is a fragmentary side view looking along the line 5-5 in FIG. 3;
  • FIGS. 6, 7 and 8 are a series of fragmentary stop motion views showing the alarm mechanism set, triggered, and shut off respectively.
  • FIG. 9 is a side elevation similar to FIG. 2 but showing the clock pressed for shut-off.
  • the clock mechanism 10 is mounted in a housing 11 seated on a supporting surface 12.
  • the clock frame includes 3,371,473 Patented Mar. 5, I968 front and back frame plates, portions of which have been indicated at 13, 14 respectively. Since electric alarm clock mechanisms are well known in the art, elements common to all such clocks have been purposely omitted or shown simply diagrammatically.
  • the clock includes a small synchronous motor 15 and a gear drive train 16 mechanically coupled via a connection 17 to an hour Wheel 18.
  • the hour wheel is coupled to an hour hand 20 which will be understood to have an associated minute hand (not shown) geared to it.
  • a buzzer blade is provided in the usual form of a length of spring metal anchored to the clock frame upon a bracket 26 and cooperating with an auxiliary pole 27 formed as part of the pole structure of the motor 15.
  • an alarm control lever 30 is employed having a first arm 31 and a second arm 32 centrally pivoted at a notch 33 formed in the frame plate 14. The lever is biased clockwise as shown in FIG. 1 by means of a biasing spring 34.
  • a gear or index wheel is used concentric with and adjacent to the hour wheel 18, the index wheel being settable in its phase position by an alarm set knob 41.
  • a cam 42 is secured on the index wheel capable of registering with a complementary slot 43 in the hour wheel.
  • the cam serves to press the hour wheel 18 away from the index wheel. This causes the alarm control lever 30 to be rocked in the counterclockwise direction (as viewed in FIG. 1) cansing the arm 32 of the lever to press against the buzzer blade to prevent the blade from vibrating-in short, the alarm remains turned off.
  • a shut-off member or plunger which extends downwardly from the clock housing adjacent the rear edge thereof and which is internally connected to a slide member at the front of the clock, the latter being disablingly coupled to the buzzer blade.
  • a rockable edge is provided along the front edge of the clock housing in constant engagement with the supporting surface, and the shut-off member, which is located rearwardly thereof serves to support the rear of the clock in slightly elevated position so that a light touch applied to the top of the clock housing serves to rock the housing rearwardly to press the shut-0H member inwardly and thereby to turn off the alarm.
  • movement is transmitted from the shut-off member to the slide at the front of the clock via a coupling lever which extends generally horizontally within the housing.
  • shut-off plunger which extends downwardly through the housing and which terminates in a button 51 engaging the supporting surface 12.
  • the plunger is connected to a lever 52 which is centrally pivoted at 53 in the frame plate 14 and which has a front end 54-.
  • a shut-off slide 55 which is vertically slidable against the front plate 13. Rivets 56, 57 registering with slots 58, 59 serve to hold the slide captive while permitting vertical movement thereof.
  • the front end of the lever may be coupled to the lower end of the slide by forming a receiving notch 60 in the latter.
  • the alarm controllever 30 For engaging the upper end of the slide, the alarm controllever 30 preferably has an integral extension forming a cam follower surface 61, while the end of the slide is angled to form a downwardly facingcamming surface 62.
  • the surfaces 61,62 are out of engagement so,v that the alarm mechanism is free to sound/out when the
  • a base is provided on the housing having arockable edge 70 defined by two short downwardly.
  • alarm clock mechanisms of conventional design may be utilized, with the touch feature being added with minimum modification and at minimum expense. Only two moving parts are necessary, the shut-off plunger with its associated lever and the vertical slide with its associated cam surface. The lever occupies a normally unused position at the bottom of the mechanism and the slide occupies unused space adjacent the front frame plate. For the purpose of providing clearance for the train of gears and setting gears which normally form a part of the alarm clock mechanism, the slide is formed into offset or C shape as shown in profile in FIG. 3.
  • the plunger 5t may be screwed into the lever 52.
  • the plunger is simply inserted in the opening provided at the bottom of the housing and its threaded tip screwed tight. The procedure is reversed for disassembly.
  • shut-off means at the upper end of the slide may be disablingly coupled to a clapper, or clapper controlling element in a clock of the manually-wound type.
  • an electric clock comprising'a clock frame having a frame plate, a housing enclosing the frame and having a rockable front edgefor engaging a supporting surface, an AC motor having an auxiliary pole and an associated buzzer blade, aclock mechanism drivingly connected to the motor and having an hour wheel, a settable index wheel adjacent thereto, means for producing relative axial movement of one of the wheels from a first to a second position as the hour wheel is rotated into register with the index wheel, means for.
  • a fiat vertically reciprocating slide arranged closely adjacent the frame plate and disablingly coupled to the buzzer blade, a touch responsive shut-off member connected to the slide and extending downwardly from they housing for engagement with the supporting surface at a point rearwardly spaced from the rockable front edge, said shut-off member being movable between (a) a downwardly projecting position and (b) an inwardly pressed position in which the buzzer blade is disabled to shut off the alarm, said shut-off member having frictional means for normally holding thesame in its projecting position for holding the rear portion of the housing slightlyelevated from the supporting surface while permitting inward movement of the member upon application of a light downward touch to the top of the clock housing.
  • shutoff member extending downwardly for engagement with t the supporting surface, said shut-off member being movable between a downwardly projecting clock supporting position and an inwardly pressed position, means including a slide member reciprocating in a vertical plane immediately adjacent the front frame plate of the clock and disablingly coupled to the alarm device, a horizontallyextending lever rigidly coupled to the shut-01f member and the slide member so that the alarm device is disabled when the shutoff member is in its inwardly-pressed position, and shut-01f member having means for holding the same in its projecting position for supporting the housing slightly elevated from the supporting surface while permitting inward movement of the shut-off member upon application of a light downward touch to the
