Abstract: A screw and toggle fastener in which the toggle member is formed from spring steel so as to be flexible but non-expandable. The toggle member is provided with a centrally located aperture to permit the threaded insertion of a screw member. The toggle member has a leading portion with respect to the central aperture which may be provided with a pointed leading edge to facilitate insertion through a member to which it is to be attached. A trailing portion of the toggle member is arcuately deformed out of the plane of the leading portion by an amount which permits pivotal movement of the toggle member with respect to the axis of the screw member so that it forms a bridging contact with the threads of the screw member when the toggle member is at right angles to the screw member after passing through the members being fastened together.

Abstract: An apparatus for locating and guiding a dipstick used to measure the level of oil in a crankcase of an automobile engine and for wiping excess or residual oil from the dipstick. For existing vehicles, an adaptor is provided which is secured to the exterior of a dipstick tube. The adaptor has a lower section which engages the dipstick tube, an intermediate seciton to receive a cap member for the tube, and an upwardly extending funnel-shaped top section serving as an easy locator for the lower end of the dipstick. The upper edge of the funnel-shaped top section is provided with one or more wiper slots to wipe residual oil from the dipstick. For new automobiles, the dipstick tube is formed with a flared-funnel top which preferably terminates in a cylindrical vertical wall in which at least one wiper slot is provided. The handle of the dipstick is provided with a plug-like member from which the dipstick is subtended and which also carries a cover member to prevent excessive oil contamination.
