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.
