  • Patent number: 6871440
    Abstract: An L-shaped tube has a horizontal member that fits into a trailer hitch, and a vertical member. A platform is secured to a post that fits into the vertical member. The platform has bolt holes arranged to engage a variety of commercial clay target throwers and a gun/pistol rest. A threaded dowel is inserted through the a 180 degree horizontal slot in the vertical member, and screwed into a threaded hole in the post, thereby limiting the range the platform post can swivel within the vertical member. The dowel can be tightened to lock the post between zero and one-hundred-eighty degrees. A tension cable secures the vertical member to the vehicle to attenuate vibrations. A gun/pistol rest configured to mount from the platform has a forward cradle for a gun stock or barrel, and rear mount that variously functions as a rifle-butt cradle or a pistol-butt support.

  • Patent number: 6684550
    Abstract: A mounting system for clay target thrower and rifle/pistol rest (10) having a hollow extender (12) which has an elongated square extender male member (12A) having an extender male member opening (12AA) therethrough. An extender horizontal member (12B) is securely fastened at a front distal end to a rear distal end of the extender male member (12A). An extender vertical member (12C) is securely fastened at a bottom distal end to a rear distal end of the extender horizontal member (12B). A mounting system for clay target thrower and rifle/pistol rest (10) having a holder (14) removably insertable into the extender (12). The holder (14) comprises a holder platform (14A) securely attached to a top distal end of a holder upper member (14B) which is attached at a lower distal end to a top distal end of a holder lower member (14C) having a holder ring (14D) therebetween. The holder platform (14A) comprises at least one holder platform opening (14AA) therethrough.
