In preferred forms of this invention, a thin, non-yieldable (generally metal) strip is helically wound on a cylindrical base member with the helically wound resilient strip interposed between adjacent wraps thereof. The non-yieldable strip may include right angle tabs spaced at intervals along the length thereof which mate with spaces provided therefor in the grooved portions of the resilient strip.

Abstract: A sole and heel construction such as used on overshoes, boots or shoes having a resilient planar body with a plurality of spaced thin fins that extend transversely across the body. The fins are evenly spaced and uniform in width throughout. All fins are identical and are inclined relative to a horizontal plane such that any weight applied to the sole compresses the fins to trap air between adjacent fins to minimize mud build-up.

Abstract: A flip-up visor assembly for a protective sport helmet or the like, in which a band secured at spaced points along the length and intermediate the ends thereof across the brow portion of a helmet with resilient pads disposed between the free band ends and the outer surface of the helmet to accommodate a range of helmet sizes carries adjacent its ends a pair of pivot pins which pivotally support the visor lens frame for movement between a position at which the visor lens is in front of the upper portion of the wearer's face and a position over the helmet at which the lens is clear of the wearer's face. Associated with the pivot pins are interengageable positive stop means for limiting the movement of the frame between its two extreme limit positions and spring loaded detent means for releasable retaining the visor in its limit positions and in spaced positions intermediate its limit positions.

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.

Abstract: A one piece bib having slits for providing a head opening and having a pocket for catching spilled food and the like is made from a single sheet. The lower longitudinal edges of a generally oblong sheet are cut away on the bias; the sheet is folded on the longitudinal center line and the lower edges are sealed together. When the sheet is unfolded, a V-shaped pocket has been formed to stand open to receive any food that has been spilled by the wearer.In the method of making the bib slits may be cut in an elongated sheet adjacent its upper edge to define a head opening. In the same operation, longitudinal edge portions or corners at the lower end are cut off on a bias, and folds are formed at the longitudinal center line and from the longitudinal center line to opposite edges of the bib at the upper severing points where the material is cut away. The sheet is then folded along the center line and the lower edges are sealed. When the bib is unfolded a V-shaped pocket has been formed.
