I JOHANNES CORNELUS WILHELMUS PAUWELS, of The Hague, Netherlands, Civil
Engineer, do hereby declare the nature of this invention to be as follows
-
This Invention relates to improved means of joining or fastening pieces of wood or
other material together also applicable as a toy, the object being to construct a joint
that shall be very firm and so that the two parts that are joined together will be as
strong as one piece.
It can also be used as a puzzle, i.e., to find the way to separate the parts.
In carrying out my invention I proceed as follows:-
One portion of wood or other material has grooves cut therein (the bottom thereof
being broader than at the top) at each side, leaving in the centre a portion of the
wood or other material considerably larger than the grooves.
The other portion is cut so that the parts exactly fit in these grooves i.e. a groove
or place is cut for the centre part to run in and a piece on each side is cut away
leaving raised portions between them & the centre groove to run in the grooves of the
first piece.
These parts must be cut exactly true so that they fit completely one in the other.
By this arrangement a firm and solid jointing is obtained without the use of screws,
glue or other article.
For use as a puzzle the joints will not be made quite so tight but tight enough to
hold firmly and appear as one piece of wood, the puzzle being to find how to separate
the parts.

I JOHANNES CORNELUS WILHELMUS PAUWELS of the Hague, Netherlands, Civil
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to improved means of joining or fastening pieces of wood or
other material together, also applicable as a toy, the object being to construct a joint
that shall be very firm and so that the two parts that are joined together will be as
strong as one piece.
It can also be used as a puzzle i.e. to find the way to separate the parts.
In carrying out my invention I proceed as follows:-
One portion of wood or other material has grooves cut therein, (the bottom thereof
being broader than at the top) at each side, leaving in the centre a portion of the
wood or other material considerably larger than the grooves.
The other portion is cut so that the parts exactly fit in these grooves i.e. a groove or
place is cut for the centre part to run in and a piece on each side is cut away leaving
raised portions between them and the centre groove to run in the grooves of the first
piece.
These parts must be cut exactly true so that they fit completely one in the other.
By this arrangement a firm and solid jointing is obtained without the use of screws
glue or other article.
For use as a puzzle, the joints will not be made quite so tight, but tight enough to
hold firmly and appear as one piece of wood, the puzzle being to find how to separate
the parts.
And in order that my invention may be more easily understood I have shewn the
same on the accompanying sheet of drawings, in which Fig. 1 is a sectional elevation
of one half of the wood or other material cut ready for use, Fig. 2 being a sectional
elevation of the other half. Fig. 3 is a plan view of the piece shewn at Fig. 1 and
Fig. 4 a like plan of Fig. 2.
The projecting parts A. A. A. in Figs. 1 & 3 slide into the grooves C. C. C... Figs. 2
& 4, and the projecting parts D. D... Figs. 2 & 4, slide into the grooves B. B.
Figs. 1 & 3, forming either a very firm joint or one suitable for a puzzle, as required.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
The improved means of joining or fastening pieces of wood or other material
together, applicable as a puzzle as hereinbefore described and shewn, and for the
purpose set forth.
