Abstract: A system by which the torque applied to a fastener such as a bolt or nut may be measured simply and accurately. More particularly, the invention relates to apparatus and methods by which the torque applied to a fastener by a socket wrench can be measured through a simplified extension element accurately and displayed quickly so that the placement of possibly damaging excessive amounts of pressure on the fastener can be avoided.

Abstract: A shock and vibration handle for application to the hand gripping portion of the normal handle of an impacted, vibration sensitive item, such as, a tennis racket, a racquetball racket, a golf club, a baseball bat, and other impact devices, such as hammers, and the like. The shock and vibration absorbent handle includes an inner tubular isolation shell of shock and vibration absorbent material mounted on the hand gripping portion of the normal handle. An outer tubular shell is mounted around shock absorbent material, and has it wrapped therearound a covering material. The absorbent material may be employed as longitudinal strips, spaced around the periphery of the handle or an integral, single piece tubular member. The inner tubular shells of absorbent material may be mounted on an inner tubular mounting shell which is mounted on the handle, and which has operatively mounted therein a cantilever spring beam having a weight on the free end thereof.

Abstract: A folding bicycle with a hinged frame comprising a front portion and a rear portion. The front and rear frame portions are connected by a hinge structure which permits the front frame portion to be rotated about the vertical axis of the hinge structure to a position against the rear frame portion for easy carrying or for insertion into a carrying bag. The folding bicycle is provided with a folding handlebar assembly which can be quickly adjusted from a standard ten speed driving configuration to a more relaxed touring handlebar configuration, or to a fully collapsed compact carrying position. The folding bicycle is provided with an adjustable soft ride seat, and with pedals which are reversible to reduce the overall width of the collapsed bicycle.
