  • Patent number: 4179836
    Abstract: An efficient mole catcher is comprised of a pair of hooks with sharp ends that are advantageously barbed and which are placed upright in or on both ends of a board of like base so as to be adapted to catch a mole or the like varmint due to the moving along of the mole its runway so as to go over the first hook without notice; then bump into and get jabbed by the point of the second hook which it runs into causing it to sharply back up and get firmly stuck on the other lead hook then behind him which thus leaves the varmint fixed and snagged to be trapped there to sooner or later die and/or rot in its hole.

  • Patent number: 4050439
    Abstract: A sling-shot device comprises, in basic assembly, an enclosed, generally circular "tine" section or impeller holder fixed on the grip or handle portion of the assembly with provision in said circular "tine" section for angularly and rotatably adjusting the secured ends of the elastic power band or the like or equivalent sling or impeller member, said ends being mounted secure at more or less diametrically opposed points located circumferentially on said circular "tine" section so that at least substantially perpendicular aiming (or sighting) and "firing" of the sling-shot is facilitated regardless of the position assumed in operational holding of the sling-shot when other-than-perpendicular (to the ground) handle dispositions are encountered; this accommodating a natural and most comfortable and desired body stance and head-cocking positional relationship assumed because of individual physique, style and mannerism for any given shooter using the sling-shot.
