PROVISIONAL SPECIFICATION.
Improvements in Dovetailing the Corners of Boxes, Drawers, and
similar Joints of Woodwork.
I RUPERT ROBINSON of Totley Rise, Sheffield in the County of York, Manager do
hereby declare the nature of my invention to be as follows:-
Hitherto it has been customary in dovetailing the corners of boxes, drawers and the
like, to make the adjacent edges of the boards square, and to cut dovetail grooves or
slots in one edge, and dovetail projections to correspond on the other edge, and fit the
two together.
Such a dovetailed joint can be drawn apart in one direction.
In carrying out my invention, I mitre the two edges of the boards which are to be
joined so that when put together they form a square, I then cut dovetailed grooves or
slots across the corner, through both boards, or I may cut such grooves or slots in the
boards separately, making them to correspond with those in the other board.
I then prepare bevelled pieces of wood or other material to fit the dovetailed slots
and drive them in, preferably securing them permanently by glue.
Dated the 23rd day of November 1896.

Improvements in Dovetailing the Corners of Boxes, Drawers, and
similar Joints of Woodwork.
I, RUPERT ROBINSON of Totley Rise, Sheffield in the County of York, Manager do
hereby declare the nature of this invention and in what manner the same has to be
performed, to be particularly described and ascertained in and by the following
statement:-
It has heretofore been customary in dovetailing the corners of boxes, drawers and
the like, to make the adjacent edges of the boards square, and to cut dovetailed
grooves or slots in one edge, and dovetailed projections upon the other to correspond
with the grooves, and to fit the two parts together, and a dovetailed joint so made
can be drawn apart in one direction.
My improvements are illustrated in the annexed drawings.
Fig. 1, shows two views of a dovetailed piece of wood, which I will call a key.
Fig. 2, shows an undercut slot made through the mitred edge of the board.
Fig. 3, shows (in section) the completed joint.

page_text: In carrying out my invention I mitre the two edges of the boards B1 and B2, which
are to be joined so that when put together they will form a square as shown in Fig. 3,
I then cut dovetailed grooves or slots S, see Fig. 2, through the mitred edges of the
boards and I may do this work to each board separately, or while the two boards are
in juxta-position as in Fig. 3.
I also prepare dovetailed pieces of wood or other material suited to the purpose,
such as is shown in Fig. 1, to fit tightly into the corresponding slots S, and which
when driven into position and dressed off flush with the boards form keys K, which
bind the boards firmly together.
Such keys may be made of metal or other substance capable of being cast or other-
wise moulded to the finished shape shown in Fig. 3, and 4, and additional means may
be used to permanently secure them in position, such as glue or cement, or by the
use of nails, wire, or such like devices.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The improvements in dovetailing the corners of boxes, drawers and the like joints
of woodwork, as hereinbefore described and shown.
The construction of rectangular joints in boxes and the like, by mitreing the
adjacent edges, forming therein a dovetailed or undercut slot S, and fitting therein a
correspondingly dovetailed key K, substantially as herein before described and shown
Dated the 24th day of August 1897.
