  • Patent number: 7805889
    Abstract: Apparatus and method for controlling flow of water from a roof valley into guttering comprising: a generally rectangular, generally planar piece of stock material having two substantially parallel side edges, a back end edge and a right-angle V-shaped front edge, an area of the material that is perforated with a plurality of open slots for allowing rainwater but not debris therethrough; and a front wall that extends downward at the front edge. Sidewalls with vertical slits extend downward at the side edges for raising the stock material above the roof surfaces. Pleats in the front wall enable a preferred installation method that laterally curves the stock material, depressing a longitudinal centerline below the side edges. The method further includes trimming the sidewalls to decrease in height front to back to allow inserting the back end under singles, and securing the front wall within an outward wall of the guttering.

  • Patent number: 7748171
    Abstract: A gutter shield for separating debris from water entering a gutter, the shield being intended for installation over a conventional longitudinally extending gutter that is mounted outboard from and below a longitudinally extending roof edge. The gutter shield includes a longitudinally extending length of planar stock material that is perforated by a plurality of intermittent, longitudinally extending slots, each slot being at the outboard edge of a tab that ramps downward and outward from a top surface of the stock material; and a longitudinally extending ridge extending downward from an underside of the shield for the purpose of breaking up water sheeting along the underside of the shield. The tab is elongated in ways that discourage sheeting while encouraging flow rate by entraining. Capillary action in opposition to water sheeting on the top surface of the shield is encouraging by gradually and smoothly curving the bend at an inboard bent edge of the tab.

  • Patent number: 7021096
    Abstract: A method, a front gauge and a sheet bending brake with a front gauge providing a scale for gauging a workpiece of sheet material, and optionally also for supporting the workpiece and/or squaring or angling the workpiece relative to a bending anvil of the brake. Mounting, either front mounting on a bending member or under-mounting below the brake, connects the scale to the brake, preferably removably and repositionably, such that the scale extends in front of the brake and under the workpiece, thereby enabling simple and efficient one-operator use without interfering with brake operation. The mounting also provides means for removably and repositionably attaching accessories such as a workpiece support and a workpiece rack.

  • Patent number: 4998374
    Abstract: A fishing device known as a spreader for trolling a plurality of baited hooks from a single fishing line wherein the spreader is a planar device with sweep arms extending from the body of the planar device and vanes that cause it to rotate as it moves relative to the water, thereby causing at least two fishing lures attached to the sweep arms to move in a helical pattern simulating the motion of fish swimming together. The hydrodynamic design provides for smooth operation in the water and reduces the propensity for the fishing lures to become entangled. The sweep arms pivot from a use position, in which position the arms are extended, to a storage position, in which position the arms are juxtaposed.
