Abstract
Abstract Belt sanding apparatus including a frame having parallel, spaced horizontal tubular elements, mounting head elements which are slideably positioned on the horizontal tubular elements, table members pivotally attached to vertical tubular elements adjustably mounted in the mounting head elements, the table members being adjustable as to fixed positions relative to horizontal about an axis perpendicular to the horizontal tubular elements of the frame, and a sanding mechanism, mounted upon an arbor element which is pivotally attached also to vertical tubular elements adjustably mounted in another mounting head element, the arbor element being adjustable as to fixed positions relative to horizontal, with the sanding mechanism including a rotatable sanding belt, a guide for the sanding belt adapting the belt to travel an extended path transversely of the horizontal tubular elements of the frame, and further including the motor drive for the sanding belt, whereby the apparatus is adapted to expose the edge of a work-piece, e.g., a flat wooden board, placed upon one of the table members to varying vertical angles of contact, i.e., from zero to 90 degrees, with the rotating sanding belt to sand the work-piece in a direction transversely of the horizontal tubular elements of the frame.

Claim 1
Independent Claim
392 words
A belt sanding apparatus comprising: (a) a frame, including a pair of spaced, parallel, horizontal tubular elements disposed adjacent the top of said frame, (b) three mounting head elements positioned on said pair of horizontal tubular elements of said frame and adapted for slideable engaging movement with and along said horizontal tubular elements, said mounting head elements including means for releaseably fixing same in particular positions longitudinally of said horizontal tubular elements, said mounting head elements each being provided with spaced, vertical openings therein and with a pair of spaced, parallel, vertical tubular elements which are received in slideable engagement within said vertical openings, each of said mounting head elements being provided with means for adjusting and releaseably fixing the respective pair of vertical tubular elements located thereon in a particular vertical location, (c) a table member attached above and to each of the respective two mounting head elements adjacent the ends of said frame, each of said table members being attached to said mounting head elements through the respective vertical tubular elements thereof and being adapted for pivotal movement about a horizontal axis perpendicular to said horizontal tubular elements of said frame, each of said table members being provided with means for releaseably fixing the particular angular positioning thereof relative to horizontal, (d) an arbor element attached above and to the middle of said mounting head elements, said arbor element being attached to said mounting head element through said vertical tubular elements thereof and being adapted for pivotal movement about a horizontal axis perpendicular to said horizontal tubular elements of said frame, said arbor element being provided with means for releaseably fixing the particular angular positioning thereof relative to horizontal, (e) a sanding mechanism mounted on and moveable with said arbor element, said sanding mechanism including a rotatable sanding belt, guide means for said sanding belt adapting said sanding belt to rotate about a path including an extended path parallel to the widths of said table members and transversely of said horizontal tubular elements of said frame, and motor means for driving said sanding belt, said sanding mechanism being adapted to expose the edge of a flat work-piece positioned on one of said table members to varying vertical angles of contact with said sanding belt to sand said work-piece in a direction transversely of said horizontal tubular elements of said frame.

Claim 3
Dependent Claim
28 words
The belt sanding apparatus according to claim 1 wherein said vertical angle said sanding belt is adapted to contact said work-piece is variable between zero and 90 degrees.
