Abstract: A mechanism for extending and retracting a retainer strap for eyewear. The strap is disposed in one or both hollow temples of an eyeglass frame and is manually extended, retracted, and locked by an extension which slides in a port or passageway forming a track or slot disposed in one surface of the temple extending from the interior to the exterior of the temple. The extension provides the means to manually retract the strap from an extended position, which extended position is achieved by pulling out the strap from the rearward end, and may be used to form one component of a locking mechanism for the strap either in the extended or retracted position. The retainer straps may be either elastic, inelastic, or one of each to provide for different modes of use.

Abstract: Power switching apparatus for an electrically driven vehicle drawing power from a plurality of spaced apart ground disposed busses separated by insulators. The apparatus employs a pair of contacts for routing power from the busses to the vehicle motor, the speed of which is controlled by the power frequency presented at each successive buss as the vehicle proceeds on its journey. The contacts are serially positioned one after another with respect to the line of travel of the vehicle and are joined together by a switching mechanism which senses the power status of each contact at any particular moment. Power is transferred to the vehicle motor through one contact or the other in accordance with a selected sequence of operation. Voltage arcing and power lapse conditions are substantially alleviated by this arrangement.

Abstract: A temple construction arrangement for eyewear incorporating a retractable retaining strap in a hollow temple to form a part of and be attached to eyewear such as eye sight correction glasses, sunglasses, safety and protection goggles, and the like. The temple is separated or split lengthwise into two haves and a rotatable bearing, positioned transverse the length or longitudinal axis of the temple, is placed at the temple end attachable to the lens holding frame between the two halves. The retractable strap is disposed within and along the length of one side of the temple and, in combination with a longitudinal stretchable retracting member such as a spring or elastic cord, passes around the bearing. The attached retracting member is disposed along the length of the opposite side of the temple from that of the strap providing a retraction force for the retaining strap. The temple halves are then joined together to enclose the bearing, retaining strap, and retracting member as a finished unit.
