Abstract: The valved discharge opening of a cylinder containing pressurized fluid is protected by a safety cap assembly including a dome-shaped cap that is detachably secured to a collar which is in turn threadedly engaged with the existing threaded cap ring flange of the cylinder. The collar is provided with a pair of locking tabs which are spring-biased to extend outwardly through a pair of opposed circumferential slots formed in the collar for locking engagement through a pair of corresponding opposed circumferential slots formed in the cap. The cap and collar further include cooperating recesses for water drainage, an aperture formed in one locking tab to permit the attachment of a wire seal, and a passageway extending transversely through the sidewall of the collar for receiving a punch to deform the thread inwardly to lock the collar to the ring cap flange.

Abstract: A cap assembly for protecting the valved fitting of a pressurized fluid cylinder of the type provided with an externally threaded cap ring. The assembly includes an internally threaded adaptor ring engageable on the cap ring and a dome-shaped cap for enclosing and protecting the valved fitting, the cap being provided with opposed latches for detachable engagement with the adaptor ring.

Abstract: A pressurized cylinder has a cap mounted thereto. The cap has a skirt wall of corrugated configuration to form a plurality of radially inwardly opening channels which alternate circumferentially with radially outwardly opening channels. A plurality of coplanar, circumferentially extending grooves or slits are formed in the outwardly open channels so as to extend radially completely therethrough. The cap is inserted longitudinally onto the cylinder such that a plurality of tabs carried by the cylinder travel longitudinally within the radially inwardly open channels. Thereafter, the cap is rotated such that the tabs enter the grooves to prevent longitudinal removal of the cap. A yieldable latch locks the cap in its secured position.

Abstract: A pressurized cylinder has a cap mounted thereto by a coupling comprising tabs in the cap which are rotatable within an annular groove carried by the cylinder. Stops are provided which limit rotation of the cap in both directions once the cap is installed. One of the stops comprises a movable latch which can be released to permit the cap to be removed by rearward rotation. The tabs are loosely disposed within the groove to minimize chances of the tabs becoming rusted thereto. The tabs are of elongate dimension in the circumferential direction to maximize the resistance to inadvertent dislodgement of the cap. The tabs are formed separately of the cap and are mounted within slits formed in a ductile wall of the cap to render the arrangement more shock resistant.

Abstract: An apparatus for storing multiple pairs of skis in bottom-to-bottom facing arrangement and in a generally upright orientation, with the skis contacting one another at forward and rearward contact zones, includes a generally upright support on which individually adjustable sets of upper and lower clamping assemblies are positioned. Both the upper clamping assembly and the lower clamping assembly of each set are operable to apply a releasable clamping force against the top surfaces of the associated pair of skis. At least one of the clamping assemblies is movable toward and away from the other one, whereby the clamping forces may be applied at spaced locations relative to the forward and rearward contact zones so as to restrain warping of the stored pair of skis. The support is rotatably mounted on a dish-like receptacle for melted snow.
