Wood joint for a barrelhead

1. A heading for use in forming a barrelhead having a water tight joint comprising an upper surface, a bottom surface, a first end, a second end, a first profile at the first end comprising an upper lobe, a lower lobe, a flat section intermediate the lobes, an upper socket portion adjacent the upper lobe with the upper socket portion extending to the upper surface, and a lower socket portion adjacent the lower lobe with the lower socket portion extending to the bottom surface, and a second profile at the second end comprising an upper socket, a lower socket, a flat section intermediate the sockets, an upper lobe portion adjacent to the upper socket with the upper lobe portion extending to the upper surface, and a lower lobe portion adjacent the lower socket with the lower lobe portion extending to the bottom surface.

2. The heading of claim 1 wherein a plurality of headings are joined together to form a barrelhead with the first profile of one of the headings for engaging with the second profile of another one of the headings.

3. The heading of claim 2 wherein any liquid is prevented from flowing from the bottom surfaces of the headings to the upper surfaces of the headings by the lower lobe of one heading and the lower lobe portion of another one of the headings swelling.

4. The heading of claim 2 wherein any liquid is prevented from flowing from the bottom surfaces of the headings to the upper surfaces of the headings by the upper lobe of one heading and the upper lobe portion of another one of the headings swelling.

5. The heading of claim 1 wherein the lower socket portion of the first profile forms a right angle at the bottom surface and the lower lobe portion of the second profile forms a right angle at the bottom surface.

6. A barrelhead having a water tight joint comprising:

a first heading having an upper surface, a bottom surface, a first profile comprising an upper lobe, a lower lobe, a flat section intermediate the lobes, an upper socket portion adjacent the upper lobe with the upper socket portion extending to the upper surface, and a lower socket portion adjacent the lower lobe with the lower socket portion extending to the bottom surface;

a second heading having an upper surface, a bottom surface, a second profile comprising an upper socket, a lower socket, a flat section intermediate the sockets, an upper lobe portion adjacent the upper socket with the upper lobe portion extending to the upper surface, and a lower lobe portion adjacent the lower socket with the lower lobe portion extending to the bottom surface; and

the first profile for engaging the second profile for securing the headings together for forming a water tight joint.

7. The barrelhead of claim 6 wherein the first heading further comprises a second profile comprising an upper socket, a lower socket, a flat section intermediate the sockets, an upper lobe portion adjacent the upper socket with the upper lobe portion extending to the upper surface, and a lower lobe portion adjacent the lower socket with the lower lobe portion extending to the bottom surface.

8. The barrelhead of claim 6 wherein the second heading further comprises a first profile comprising an upper lobe, a lower lobe, a flat section intermediate the lobes, an upper socket portion adjacent the upper lobe with the upper socket portion extending to the upper surface, and a lower socket portion adjacent the lower lobe with the lower socket portion extending to the bottom surface.

9. The barrelhead of claim 6 wherein any liquid is prevented from flowing from the bottom surfaces of the headings to the upper surfaces of the headings by the lower lobe of the first heading and the lower lobe portion of the second heading swelling.

10. The barrelhead of claim 9 wherein any liquid is prevented from flowing from the bottom surfaces of the headings to the upper surfaces of the headings by the upper lobe of the first heading and the upper lobe portion of the second heading swelling.

11. The barrelhead of claim 6 wherein any liquid is prevented from flowing from the bottom surfaces of the headings to the upper surfaces of the headings by the lower lobe of the first heading and the lower lobe portion of the second heading and the upper lobe of the first heading and the upper lobe portion of the second heading swelling.

12. A barrelhead having a water tight joint comprising:

a first heading having an upper surface, a bottom surface, a first profile having a knob shaped tongue portion having an upper lobe, a lower lobe, a flat section intermediate the lobes, an upper socket portion adjacent the upper lobe with the upper socket portion extending to the upper surface, and a lower socket portion adjacent the lower lobe with the lower socket portion extending to the bottom surface;

a second heading having an upper surface, a bottom surface, a second profile having a knob shaped socket portion having an upper socket, a lower socket, a flat section intermediate the sockets, an upper lobe portion adjacent the upper socket with the upper lobe portion extending to the upper surface, and a lower lobe portion adjacent the lower socket with the lower lobe portion extending to the bottom surface; and

the first profile for engaging the second profile for securing the headings together for forming a water tight joint.

13. The barrelhead of claim 12 wherein the first heading further comprises a second profile comprising a knob like socket portion having an upper socket, a lower socket, a flat section intermediate the sockets, an upper lobe portion adjacent the upper socket with the upper lobe portion extending to the upper surface, and a lower lobe portion adjacent the lower socket with the lower lobe portion extending to the bottom surface.

14. The barrelhead of claim 12 wherein the second heading further comprises a first profile comprising a knob shaped tongue portion having an upper lobe, a lower lobe, a flat section intermediate the lobes, an upper socket portion adjacent the upper lobe with the upper socket portion extending to the upper surface, and a lower socket portion adjacent the lower lobe with the lower socket portion extending to the bottom surface.

15. The barrelhead of claim 12 wherein any liquid is prevented from flowing from the bottom surfaces of the headings to the upper surfaces of the headings by the lower lobe of the tongue portion of the first heading and the lower lobe portion of the socket portion of the second heading swelling.
