  • Patent number: 7762245
    Abstract: The present invention is an improved compound bow. In particular, the present invention is directed to an adjustable compound bow for hunting and archery with noise reduction features. The preferred embodiment of the bow comprises a riser having a main riser length with two ends, each end attached to an adjustable hub with a limb base. Each limb base preferably has a pocketless flat surface with vibration dampening material. Each hub is secured to the main riser length by an adjustment worm drive and a hub pivot. A limb is preferably secured to each limb base at two points on the pocketless flat surface. A bowstring is strung under tension between the limbs. The bowstring's tension can be adjusted by adjusting the adjustable hubs with the worm drives. The bow preferably has a storage position and an in-use position caused by rotating the limbs around the adjustable hubs. Adjustment of the bow can be accomplished without use of a bow press.

  • Patent number: 5836864
    Abstract: A cylinder and piston device provides a sheath for securing a penis into one end of the cylinder. The piston then acts to draw a vacuum for holding the cylinder and the penis together as a unit. Once a vacuum is drawn, a means for holding the piston at a preferred position is engaged. Significant weight may be applied to the device, or the device itself may contain significant mass so as to apply a stretching force onto the penis. The device provides a means for stretching a human penis and is quickly and easily applied to the penis and removed therefrom. The device enables further weight mass to be applied to enabling a program for stretch training of the penis through the application of incremental weight additions. The device prevents lateral swelling of the penis and provides a means for locking a level of vacuum that is appropriate for holding the weight involved in the procedure and that is also comfortable to the person undergoing the weight training.

  • Patent number: 5344396
    Abstract: An apparatus is provided for stretching a circumcised foreskin of a penis. A tubular body provides an outer surface. An indented portion is included at one end of the body for accepting the tip of the penis, and a passage within the body interconnects the indented portion at the one end of the body with the other end of the body. In operation, with the tip of the penis inserted into the indented portion, and the foreskin drawn toward the tip to contact the outer surface for removable attachment thereto. The weight of the body exerts a tension force within the foreskin to stretch the foreskin. Additional weights may be attached at the other end of the body. In an alternate embodiment of the invention, the body is comprised of an outer portion including the outer surface, and an inner portion including the indented portion. The inner portion is slidably and axially engaged within the outer portion.
