Stepped Or Tapered Recess In Side Patents (Class 403/253)
  • Patent number: 10471626
    Abstract: The invention is a unique modification of biscuit joinery. The instant invention creates “two way” slots in joining wood [preferred embodiment] pieces, allowing a “shelf joint” in the center of a face of wood, to be fastened with a common nickel (or similar coin or disc). Rather than using a limited biscuit cutter/biscuit joiner, the instant method discloses use of a router with a specialized router bit (aka slot cutter bit); the slot cutter on the router [when the bit is machined in the following way infra, and then configured and used in the following way infra] allows a common 5¢ piece to become the spline joining the two wood pieces or panels, thereby allowing rapid assembly & disassembly of wood furniture. The precise ratios and proportions of grooves, slots, coin wells, overhangs, pushtool ‘raceways,’ and offsets therefor, make this invention possible.

  • Patent number: 9568033
    Abstract: A mechanical fastener assembly is provided for joining two or more workpieces. The assembly includes a mechanical fastener and a slotted collar. The mechanical fastener has a shaft received within aligned bores of the workpieces, while the slotted collar surrounds at least a portion of the shaft and is also received within the aligned bores. Inserting and advancing the slotted collar into the aligned bores causes the slot of the slotted collar to at least partially close, thereby causing an inner surface of the slotted collar to engage at least a portion of the shaft of the mechanical fastener and an outer surface of the slotted collar to engage at least a portion of the aligned bores of the two workpieces. Such a mechanical fastener assembly can effectively transform a bolted joint into a stronger shear joint.
