US Patent:

20120048586, Mar 1, 2012

Filed:

Aug 27, 2010

Appl. No.:

12/869949

Inventors:

Sarah Jane Montplaisir - Kingsville MD, US
Thomas Benton Sharp - Jackson TN, US

Assignee:

Black & Decker Inc. - Newark DE

International Classification:

E21B 3/00

US Classification:

173215

Abstract:

A drill press includes a spindle pulley having a first central opening extending along an axis, a sleeve disposed within the pulley central opening, the sleeve having a central opening aligned with the pulley central opening and the axis, and a locking nut connecting an upper end of the sleeve with the spindle pulley for supporting simultaneous rotation of the sleeve and the spindle pulley about the axis. The drill press includes a spindle disposed within the sleeve central opening and extending along the axis, the spindle being slidable along the axis relative to the sleeve and being rotatable with the sleeve. The drill press includes a spacer disposed between the spindle and the locking nut or between the spindle and the sleeve for aligning the spindle with the axis and preventing the spindle from contacting the upper end of the sleeve during rotation, which reduces noise during operation.

Inventors:

Thomas Benton Sharp - Jackson TN, US

Assignee:

Black & Decker Inc. - Newark DE

International Classification:

B23B 49/00

US Classification:

408 1 R, 408 16, 408241 S

Abstract:

A drill press includes a head stock, a pinion shaft, and a quill coupled with the pinion shaft. A pinion shaft hub is connected with an outer end of the pinion shaft and is located adjacent a side wall of the head stock. The pinion shaft hub is rotatable for rotating the pinion shaft, which provides reciprocating movement to the quill along a vertical axis. A stationary zeroing element is mounted on the head stock, and a depth scale is mounted on the pinion shaft hub adjacent the stationary zeroing element. The depth scale and the pinion shaft hub are frictionally coupled together so that the depth scale normally rotates simultaneously with the pinion shaft hub, however, the depth scale is rotatable relative to the pinion shaft hub upon exceeding a friction force that normally resists movement of the depth scale relative to the pinion shaft hub.
