Abstract

A carpentry biscuit is provided having an elongated planar body formed of wood having opposed faces spaced apart and thickness T. One of the opposed faces is provided with a longitudinal alignment mark oriented along a longitudinal axis and a transverse alignment mark aligned perpendicular to the transverse axis to aid the user in positioning the biscuit in a slot formed in a pair of boards to be joined together.

Claims

1. A carpentry biscuit for use in forming a joint between mating surfaces of adjacent wooden boards each having an aligned semi-circular slot formed therein by a rotating cutter blade, the carpentry biscuit comprising:

an elongated planar body formed of wood having opposed faces spaced apart a thickness T;

a longitudinal axis and a relatively smaller transverse axis;

a longitudinal alignment mark aligned with the longitudinal axis which is formed into each of the opposed faces of the biscuit;

a transverse alignment mark aligned with the transverse axis which is formed into each of the opposed faces of the biscuit; and

a plurality of notches formed along the outer periphery of the biscuit corresponding to the longitudinal and transverse axes to aid a user in positioning the biscuit in the slot formed in at least one of a pair of boards to be joined together.

2. The carpentry biscuit of claim 1 wherein the longitudinal alignment mark is an embossed rib formed in each of the opposed faces of the biscuit which is raised relative to the remainder of the face.

3. The carpentry biscuit of claim 1 wherein the transverse alignment mark is an embossed rib formed in each of the opposed faces of the biscuit which is raised relative to the remainder of the face.

4. The carpentry biscuit of claim 1 wherein the longitudinal alignment mark is an embossed channel formed in each of the opposed faces of the biscuit which is recessed relative to the remainder of the face.

5. The carpentry biscuit of claim 1 wherein the transverse alignment mark is an embossed channel formed in each of the opposed faces of the biscuit which is recessed relative to the remainder of the face.

6. The carpentry biscuit of claim 1 wherein the biscuit is formed of a wood laminate.
