Charles Hadley Cammack has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220347766
    Abstract: This invention includes a drill guide (drill depth stop and alignment tool), canting base attachment, and self-aligning dowel jig attachment that allows users to drill holes to prescribed depths into flat work surfaces using various sizes of twist and auger bits while eliminating marring and reducing wood splintering. The canting base attachment allows users to drill holes to prescribed depths and at variable angles into flat surfaces and both large and small cylinders with no free ends using various kinds and sizes of drilling tools without marring. The dowel jig attachment allows users to drill dowel holes to prescribed depths in edges and faces of work pieces that are evenly spaced apart by numerous gauged distances and at infinitely adjustable distances from edges. This invention has drill press-like capabilities and can be used in the field and in shops.

  • Publication number: 20210362246
    Abstract: These inventions include three drill guides (Multiguide, Triguide, and Uniguide), and two attachments (canting base and dowel jig). The drill guides allow users to drill holes to prescribed depths into flat work surfaces using various sizes of bits including twist and auger bits while eliminating marring and reducing wood splintering. The canting base attachment allows users to drill holes to prescribed depths and at variable angles into flat surfaces and both large and small cylinders having zero, one, or two free ends using various kinds and sizes of drilling tools including twist, auger, and Forstner bits. The dowel jig attachment allows users to drill dowel holes to prescribed depths in edges and faces of workpieces that are evenly spaced apart by numerous gauged distances and at adjustable distances from edges without slippage or misalignment. These inventions have drill press-like capabilities and can be used in fields and shops.
