ABSTRACT:
A street name sign comprising one or more sign heads of a hollow, aluminum-frame construction mounted on a post cap via a center staff and a nut threaded thereon against the post cap is provided with a vandal-proof arm secured to the center staff, which is anchored deep in the cylindrical post or pipe supporting the sign to render the sign vandal-proof against unauthorized removal from the post and against being bent or broken by a yanking on the ends of the sign ends by one's full strength and weight. The vandal-proof arm may comprise a threaded extension of the center staff secured thereto through a staff nut used also to clamp the post cap to the sign heads, or preferably it may be an integral extension of the center staff having a one-way spring-lock washer thereon acting through a compression spring against the post cap to clamp the same to the sign heads.
Vandalism of street name signs has become a growing menace by vandals bending or breaking the signs loose from the posts and even removing the entire signs and carrying them away. Another difficulty heretofore sometimes encountered, not however of a vandal-related nature, is a "freezing" of the nut on the aluminum center staff due to corrosion arising from many years exposure to the weather, especially salt-air conditions, which prevents a disassembling of the sign structure for repair.
