Abstract

A wood joint is disclosed which comprises a first heading having a first profile comprising an upper socket, a lower socket, and a flat section intermediate the sockets, a second heading having a second profile comprising an upper socket, a lower socket, and a flat section intermediate the sockets, and a spline member having a pair of tongue portions with each of the tongue portions having an upper lobe and a lower lobe, the spline member for fitting within the first profile and the second profile.

Claims

1. A barrelhead having a water tight wood joint comprising:

a first heading having a first profile comprising an upper rounded socket, a lower rounded socket, and a flat section intermediate the rounded sockets;

a second heading having a second profile comprising an upper rounded socket, a lower rounded socket, and a flat section intermediate the rounded sockets; and

a spline member having a pair of rounded tongue portions with each of the rounded tongue portions having an upper lobe, a lower lobe, and a flat section intermediate the upper lobe and the lower lobe, the spline member for fitting within the first profile and the second profile.

2. The barrelhead having a water tight wood joint of claim 1 wherein the spline member further comprises a lower flat portion between the lower lobes.

3. The barrelhead having a water tight wood joint of claim 1 wherein the spline member further comprises an upper flat portion between the upper lobes.

4. The barrelhead having a water tight wood joint of claim 1 wherein the first heading further comprises a second profile comprising an upper rounded socket, a lower rounded socket, and a flat section intermediate the rounded sockets.

5. The barrelhead having a water tight wood joint of claim 1 wherein the second heading further comprises a first profile comprising an upper rounded socket, a lower rounded socket, and a flat section intermediate the rounded sockets.

6. The barrelhead having a water tight wood joint of claim 1 wherein the first heading has a bottom surface and a top surface and the second heading has a bottom surface and a top surface, and any liquid is prevented from flowing from the bottom surfaces of the headings to the top surfaces of the headings by the lower lobes of the spline member swelling.

7. The barrelhead having a water tight wood joint of claim 1 wherein the first heading has a bottom surface and a top surface and the second heading has a bottom surface and a top surface, and any liquid is prevented from flowing from the bottom surfaces of the headings to the top surfaces of the headings by the upper lobes of the spline member swelling.
