bar Posts for road safety barrier By www.freepatentsonline.com Published On :: Tue, 24 Mar 2015 08:00:00 EDT A road safety barrier having a plurality of ropes supported by posts rigidly mounted on or in the ground is described. Each rope is held in tension against the posts and supported in a notch or groove in a side of the posts. The ropes are released from a post and the post is not pulled from the ground when a vertical force is exerted on the rope. The ropes when weaved are tensioned against the posts and this gives use to a combined frictional resistance to displacement of the ropes relative to each post along the length of the safety barrier. The structure of at least some of the posts and/or their mounting with respect to the ground defines a minimum bending yield strength in a direction along the length of the barrier. This minimum bending yield strength is greater than the bending moment resulting from the combined frictional resistance forces acting on the post. Full Article

The core is mounted on an arbor and is inserted into a mold on a vertical die cast press having a shot chamber. The mold has upper and lower mold members defining annular cavities receiving end portions of the bars. Molten copper or aluminum is poured into the shot chamber and forced upwardly by a shot piston through passages in the lower mold member and into the cavity around the lower end portions of the bars. The pressurized molten metal solidifies and shrinks around the bar end portions to form an endring for the rotor. The core, endring and arbor are inverted and confined in the mold, and the casting steps are repeated to form the opposite endring. Full Article
bar Safety barrier netting system By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT A system for substantially enclosing the periphery of a building top with a netting system which is easily and efficiently movable or reconfigurable during the building construction process comprises a lightweight netting system for extending above a completed work area or floor, a strong lightweight structural support system for the netting, wherein the structural support system is vertically adjustable via slidable engagement with brackets attached to the floors which are already completed, provides enhanced safety for workers and for pedestrians below by preventing passage of workers or debris through the netting and enhances efficiency of construction by providing an easily reconfigurable, inexpensive and lightweight system for providing such enhanced safety.

bar MANUFACTURE OF BARREL CONSTRUCTIONS By www.freepatentsonline.com Published On :: Tue, 19 Oct 1971 08:00:00 EDT A system for producing wooden barrel constructions of the type including a plurality of staves assembled in side-by-side relationship with the assembly defining a generally circular cross section. Each stave is provided with a central bilge portion whereby the finished barrel will have a large diameter central portion and smaller diameter end portions. The individual staves are characterized by a narrow end portion and a wide end portion with the width of the bilge portion exceeding one-half the sum of the widths of the end portions. The staves are assembled in the barrel so that wide and narrow end portions are located at each end of the barrel. Full Article
bar BARREL STAVE EDGE SAWING MACHINE By www.freepatentsonline.com Published On :: Tue, 16 Jan 1973 08:00:00 EST A pair of motor driven circular saws are mounted on opposite sides of a frame supported horizontal barrel stave carrying conveyor with the axes of the saws perpendicular to the direction of conveyor travel and their planes arranged in downwardly converging relation. Spring loaded guide rollers, forming a part of the saw driving motor supports, adjusts the position of the saws in a desired barrel stave edge trimming spaced-apart relation by contact with the respective opposing longitudinal sides of a barrel stave to be trimmed as it is moved by the conveyor between the saws. Lock means actuated by spring loaded pressure rollers overlying the position of the barrel stave when moved by the conveyor maintains the adjusted spaced-apart relation of the saws for the duration of the saw trimming action on each side of each stave moved through the machine by the conveyor.

bar Barrel hoop drivers By www.freepatentsonline.com Published On :: Tue, 21 Jul 1981 08:00:00 EDT A claw for use in a barrel hoop driver which allows the top hoop of a barrel to be driven beyond the barrel edge thereby allowing barrels for reuse to have their staves tightened without fitting new end hoops. The claw has spaced guide members controlling the effective depth of a blade for engagement with the hoops, the spaced arrangement of the guide members preventing accumulation of wood shavings on the blade.
