Abstract: A dental floss manipulator which has a handle adapted to store a spool of dental floss and a fork on the free end of the handle adapted to hold the unwound dental floss under tension between the spaced fingers for insertion between the teeth; a resiliently yieldably held anchor in the handle holds the unwound dental floss under tension, and a trigger lever pivoted on the handle to which the free end of the unwound dental floss is fastened, is manipulatable against the action of the resiliently yieldable anchor to pull the dental floss between the fork fingers in opposite directions between the teeth without reciprocating the handle itself.

Abstract: In the heel of a shoe is a cavity in which the end of a leaf spring is coiled around and anchored in a fixed pin biased so that the leaf spring is normally urged away from the adjacent portion of the heel. The leaf spring is at an incline downwardly and rearwardly along an inclined bottom surface of the heel and has on it a complemental portion of the heel. The leaf spring is held against said inclined surface by a pivoted lever which latter is pressed by a coil spring around its pivot against the leaf spring thereby to press the leaf spring against the inclined surface of the heel. The lever is covered by a complemental heel portion. Between the lever and the adjacent forward part of the heel is a compressible filler which in this illustration is sponge rubber to fill the space therewith. A latching device is provided in the cavity to latch the lever in the raised position until the leaf spring has completed its downward cycle.
