Abstract

Automatic horn warning signal apparatus for use on boats is compact, unitary, self-contained, lightweight, drycell-battery-energized, is manually selectably actuated for automatically sounding any of nine predetermined patterns of warning horn signal sequences applicable to specified, recognized navigational procedures for marine craft. A small motor operates through a first speed-reducing, torque-increasing transmission for rotating a main cam shaft containing nine lobed cams each having a different configuration corresponding to the desired warning signal pattern to be sounded. A control lever is engageable with any of the nine cams for selecting the desired automatically sounded horn signal sequence. A second speed-reducing, torque-increasing transmission rotates a latching cam shaft at one-tenth the rate of the main cam shaft for operating a latch for enabling a pivot bar to serve as fulcrum for the control lever. For causing the control lever to actuate a valve for releasing pulses of compressed gas into the horn for sounding the selected warning signal sequence determined by a particular cam. The signal pattern is sounded only once during each revolution of the latching cam. When any of four signal sequences has been selected, pressing a start button causes repeated sounding of the selected signal sequence. Selecting the other five warning sequences opens the repeat switch, causing only one sounding of the signal sequence after pressing the start button. Manually depressing the horn immediately sounds a continuous blast as long as depressed.

  1. 1. Horn signal apparatus for use on boats, said apparatus comprising:a horn,valve means connected between said horn and a removable container of pressurized gas for preventingsaid valve means normally being closed for preventing pressurized gas from flowing from said container to said horn,said valve means being actuatable for allowing pressurized gas to flow from said container to said horn for sounding said horn,actuating means for actuating said valve means, said actuating means including a plurality of rotatable cams,each of said rotatable cams having a configuration corresponding to a respective horn-sounding signal sequence for actuating said valve means for allowing pressurized gas to flow to said horn for sounding said horn corresponding to the respective horn-sounding signal sequence,said respective horn-sounding signal sequences being different one from another for relating to predetermined respective boat situations in accord with marine horn-signalling protocol,electric motor drive means for driving said actuating means, electric circuit means connected to said electric motor drive means for controlling said electric motor drive means,said electric circuit means including switch means responsive to rotation of said plurality of cams for controlling energization of said electric motor drive means,speed-reducing, torque-increasing transmission means coupling said electric motor drive means to said plurality of cams for rotating said plurality of cams, andmanually-operable, mode-selection means operatively associated with said plurality of cams for selecting any one of said cams for actuating said valve means in accordance with the configuration of said selected cam.
  2. 14. Horn signal apparatus for use on boats, said apparatus comprising:a horn,valve means connected between said horn and a removable container of pressurized gas for preventing pressurized gas from flowing from said container to said horn,said valve means being actuatable for allowing pressurized gas to flow from said container to said horn for sounding said horn,actuating means for actuating said valve means, said actuating means including a plurality of rotatable cams,each of said rotatable cams having a configuration corresponding to a respective horn-sounding signal for actuating said valve means for allowing pressurized gas to flow to said horn for sounding said horn corresponding to the respective horn-sounding signal,said respective horn-sounding signals being different one from another for relating to predetermined respective horn signals in accord with marine horn-signalling protocol,controllable electric motor drive means coupled to said plurality of cams for rotating said cams, andmanually-operable, mode-selection means operatively associated with said plurality of cams for selecting any one of said cams for actuating said valve means in accordance with the configuration of said selected cam for sounding the respective horn-sounding signal.
  3. 20. Horn signal apparatus for use on boats, said apparatus comprising:a horn,valve means connected between said horn and a removable container of pressurized gas for preventing pressurized gas from flowing from said container to said horn,said valve means being actuatable into an open condition for allowing pressurized gas to flow from said container to said horn for sounding said horn,actuating means for actuating said valve means, said actuating means including a plurality of cams,each of said cams having a different cam configuration,each cam configuration being capable of actuating said valve means for sounding said horn corresponding to a respective predetermined horn-sounding signal sequence,each respective predetermined horn-sounding signal sequence corresponding to a respective predetermined marine warning signal,controllable electric drive means for simultaneously rotating said plurality of cams, andmanually-operable control means associated with said cams for selecting any one of said cams for actuating said valve means for sounding said horn to obtain the predetermined horn-sounding signal sequence produced by the selected cam.
