Abstract: A fish hook attachment is provided which includes at least one (a) hydrofoil or (b) stabilizer and hydrofoil of unitary construction secured to a hollow shank having a slot which extends along the length of the hollow shank. Each unitary construction is secured to a hook shank so that the hydrofoil portion is positioned at an angle between 5.degree. to 85.degree. degrees from the hook shank. The hydrofoil portion of the unitary construction is positioned substantially perpendicular to the plane defined by the hook shank and hook elbow. The hydrofoil is positioned below an elbow of the hook.

Abstract: A fish hook construction is provided which includes at least one stabilizer and wing of unitary construction. Each unitary construction is secured to the hook shank so that the wing portion is positioned at an angle between 30 to 60 degrees from the hook shank. The wing portion of the unitary construction is positioned substantially perpendicular to the plane defined by the shank and hook elbow.

Abstract: A fish hook construction is provided which includes a wing secured to the hook shank at an angle between 30 to 60 degrees from the hook shank in a direction toward the hook elbow as well as being positioned perpendicular to the plane defined by the shank and hook elbow.

Abstract: An apparatus for transporting personnel or materials from an upper elevation to a lower elevation. Twin guideline means are suspended between the upper and lower elevations from each of which is suspended a carrier means. The two carrier means are simultaneously moveable in opposite directions along their respective guideline means.

Abstract: In accordance with this invention, a back strengthening device is provided which includes a horizontal bar, a support for the horizontal bar and a foot platform which can be raised or lowered. Apparatus is provided on the horizontal bar to sense the application of hand grasping forces on the bar while the foot platform is provided with structure to sense weight being applied to the top surface of the platform. When the person desires to use the device, he grasps the horizontal bar to actuate the apparatus thereon while he is standing on the platform. These actions cause the platform to be lowered to a point just below contact with the feet or in mild contact with the feet as the force exerted on the platform is reduced while it is lowered away from contact with the weight of the user. The user then can hang from the horizontal bar so that all or substantially all of his weight is hanging free, thereby to stretch the back muscles.
