  • Patent number: 8087853
    Abstract: In the pocket hole apparatus of the present invention, a table reciprocates linearly relative to a base. An anvil is fixed relative to the base and holds the workpiece on a sloped top surface at the desired angle for the pocket hole. A drill spindle with a drill bit is fixed relative to the table. After the workpiece is mounted to the anvil, the table is moved to drill the pocket hole. Optionally, a second spindle on the opposite side of the anvil predrills the pocket hole when the table is first moved to a predrill position. The spindle is enabled or disabled by latching mechanism. The spindle is mounted to a rail that is slidably mounted to the table so that the rail can slide perpendicularly thereby adjusting the spacing between pocket holes.

  • Patent number: 5116169
    Abstract: An apparatus and method are provided for drilling thin-walled glass articles. The apparatus is comprised of a drilling machine having upper and lower triangulated arm assemblies to which opposing drills are attached. The arm assemblies pivot about a common shaft. The shaft is supported by a support assembly attached to a sliding table. First and second actuators mounted on the support assembly urge the arm assemblies to pivot about the shaft, thereby controlling the feed rate and stroke of the drills. In a second embodiment adapted to drill deep glass articles, the lower arm assembly has an intermediate frame which pivots about an upper shaft along with the upper arm assembly. The lower arm assembly also has a lower arm which pivots about a lower shaft under the urging of a third actuator, allowing the drill spindle attached to the lower arm to enter and withdraw from the deep article without scratching the sides of the article.

  • Patent number: 5052097
    Abstract: An improved method for forming holes in a board and an improved apparatus for practicing the improved method. Two or three linear arrays of holes are punched through the board, through its expansive faces, in a punching zone. A punch and a die coacting with the punch are used to punch each punched hole, in a press comprising a pressing ram and a pressing bed, upon relative movement of the pressing ram and the pressing bed toward each other. The board is registered in the pressing zone, in a predetermined position, by engaging its opposite edges and its opposite ends. Plural holes are drilled into each end of the board in a drilling zone. A physical measurement is conducted in an inspecting zone, by inserting a probe into each drilled hole, so as to determine whether such drilled hole has been drilled to a minimum depth. These punching, drilling, and inspecting steps of the improved method are carried out in a series of automated operations of the improved apparatus.
