Abstract:

A lead sight with numbers coinciding with the numbered positions on a standard skeet range printed on a transversely extended transparent member mounted by a strap above gun barrels toward the muzzle end. "High" and "Low", also imprinted on the transparent member, correspond to the high house and the low house from which the clay pigeons are released. The "lead sight" helps the beginner in skeet shooting to lead the bird properly and helps the experienced shooter having a problem with one or more positions.

US Classification:

Abstract:

A light weight and collapsible luggage carrier that hooks onto the rear car bumper with adjustable length support chains with end brackets mounting on a trunk rim. The luggage carrier comes in kit form that when collapsed is conveniently stored in the car trunk available for use when needed. The carrier assembled in place on the rear of an automobile includes a "U" shaped tubular metal assembly in the luggage carrier along a plurality of cross tubes as a platform support for luggage carried thereon. Rubber bumpers on the front ends of the "U" sides prevent damage to the auto rear above the rear bumper. Two opposite side support plastic sheathed chains have metal end clips that hook over the trunk rear rim and extend to exposed chain outer ends selectively connected by "S" hooks to opposite ends of the "U" shape adjacent flattened bends that prevent the "S" hooks from moving through the flattened bends. An additional plastic sheath enclosed chain extends from a hook connection to the bottom of the rear bumper to a "S" hook connection to the middle of the rear "U" tubular member.

Abstract:

A recreational twin hulled boat with the hulls interconnected by hull spacing structure with the boat convertible between outboard motor drive and sail drive. The hull spacing structure is also the mount for an outboard motor when the boat is converted for outboard motor drive with the hull spacing structure also mounting a fuel tank, operator saddle and some of the steering mechanism that includes two steering cables connected to opposite ends of a bell crank gear driven from a gear interconnect with steering handlebars. The steering cables for the motor driven conversion extend back and around idler pulleys to ultimately idler pulleys on each hull and then to connection to a rudder transverse rod interconnecting the rudders at the rear of each hull. This steering system turns the rudders in unison around their pivotal mountings opposite to the turning direction of the steering handle bars with the outboard motor locked in place so as not to pivot but to only provide thrust. In the sail conversion a tiller and rod interconnect steering system is used connected to the rudders that still employ the rudder transverse rod interconnecting the rudders at the rear of each hull.
