  • Patent number: 6735910
    Abstract: The invention is a spring loaded trap holding device which uses spring tension to securely hold a live animal trap upon the top horizontal plane of a gutter by means of hooking to a gutter spike for the anchoring of the trap. One end of a specific diameter and length of alloy rod is bent to form a hook for the purpose of hooking onto a gutter spike. A large stainless steel flat washer is then placed over the opposite end, followed by a compression spring and then by an aluminum sleeve. The opposite end of the alloy rod is bent to form a 90-degree angle forming a handle and trapping all component parts onto the alloy rod permanently. The gutter hook is placed through the trap from the top allowing the flat washer to rest upon the top of the trap. By applying downward pressure, the spring is then compressed, pushing the hook completely through to the bottom of the trap and is hooked onto the gutter spike, thus securing the trap to the gutter under spring tension.
