Abstract: A removable hood ornament is created in a manner which renders it virtually impervious to the wearing and corrosive action of time. A stock hood ornament and ornament seat element are both milled slightly. A shaft which will seat in a socket mounted on the underside of the vehicle hood is inserted up through the seat. The shaft has a threaded bifurcated top with a transverse bore therethrough which straddles the standard tongue of the ornament, with a pin passing through the bore of the shaft and through the mounting hole in the tongue to engage the shaft and tongue together. A threaded washer previously rotated onto the top of shaft is now tightened up against the underside of the ornament seat at a relatively high torque, which bends the pin and frictionally engages all of the parts together under sufficient force that for all practical purposes they will never come apart unless deliberately separated.

Abstract: A theft alarm actuator is provided for an alarm system for a hood ornament, utilizing a pair of spaced insulating plugs held apart by a coil spring and retained together by the long end of a safety pin-like clip which engages a detent in the hood ornament element, and has a long leg which passes down thrugh the plugs, with a nut engaged on the threaded end of the long leg beneath the lower contact such that deflection of the hood ornament element raises the clip, bringing the contacts, which are mounted on the plugs, together to actuate the alarm. The alarm itself is not part of the invention, and could be any electrically-operated unit actuated by closing the circuit.

Abstract: A Mercedes Benz hood ornament structure is modified to include an alarm actuator switch connected to the vehicle horn. The spring-loaded restraint which holds the hood ornament element in its upright position is affixed with a sliding contact which rises into contact with a fixed contact when the hood ornament is deflected forwardly. The two contacts are wired into the horn circuit so that the horn is actuated when the ornament element is deflected forwardly, and the geometry of the mounting for the hood element is such that deflections rearwardly and sideways, such as might occur by accident or in a car wash, will not actuate the horn.

Abstract: A theft alarm is provided for a hood ornament utilizing a pair of spaced plugs held apart by a coil spring and retained together by a central hook and threaded post which extend through axial bores through the plugs with the hook extending up through the hole in the hood to engage the hood ornament. The plugs each mount an electrical contact, and when the ornament is deflected, the coil spring is compressed between the plugs, bringing the electrical contacts into contact and setting off an alarm, which ordinarily is the vehicle's horn.
