Abstract: A caster has a horn of semi-circular configuration about an axle receiving apertured boss, a web extending radially outwardly from the boss to a semi-cylindrical flange and a pair of wheels, one on each side of the horn, the tread of the wheels being flush with the outer cylindrical surface of the flange. Hub shields are mounted on the wheels in such manner as to avoid load transmission to the shields, yet accommodating a variety of appearance features, ease of installation and reliable retention of the shields in place of the wheels.

Abstract: A knock-down device is presented for use in stacking wooden pallets, one above the other, in a manner to protect the wooden pallet against much of the damage usually encountered, and in a manner wherein the load from each pallet above the lowermost is transmitted through aligned corner posts to the supporting floor independently of the pallets. The completed device is usually composed of two identical complexes, each of which includes two adjacent sides of the stacker device arranged in such a manner that two generally L-shape structures, as seen in plan view, are secured together to form a complete rectangle in plan.

Abstract: A nail and nail clip arrangement in which so-called common nails may have their shanks grit-blasted and the edge of their heads flattened along equal parallel planes to provide a minor diametral dimension of the nail head that is approximately twice the diameter of the nail shank. The heads are alternately offset laterally in contact with each other in two rows and with the heads of the two rows alternately cross-engaging and the shanks of the nails interdigitate at an acute angle adjacent their points. The end nail at the feed end of one row extends beyond the next adjacent nail of the other row far enough for a powered driver to nip off and drive the lead nail upon actuation of the power mechanism.

Abstract: A process for forming stepped lids for microelectronic circuit cases. A plurality of interconnected lids is etched in a metal sheet with the lids oversize. Individual lids are stamped from the sheet to the desired size, providing substantially square corners at the edge of the lid and a substantially flat rim for engagement with the case.

Abstract: A caster assembly has a brake shoe member including a wheel tread contacting shoe, and a foot operable brake applying and release lever, the shoe member being guided horizontally, both longitudinally and laterally adjacent the wheel contacting shoe for positive shoe action in response to operation of the lever.

Abstract: A corner finishing tool for applying mastic material along a wall joint comprising an angular retainer plate having a pair of integral sides resiliently joined at a corner, a pair of L-shaped rigid frame members secured thereto, one side and frame member being resiliently movable relative to the other side and frame member while together defining a cavity reservoir for mastic material, and a wheel having substantially conical side surfaces that converge to a center rim. The corner finishing tool also provides means for setting the L-shaped rigid frame members to a preset position under an adjustable resilient biasing force.
