SIDNEY VIGERS 18 Abingdon Street, Westminster, London, S.W., Surveyor, do
hereby declare the nature of this invention to be as follows:-
An invention for keying or tongueing together the joints in wood floor boards or
blocks, panels or pieces of wood in joinery or packing-cases, also the joints in boards
composed of paper, papier-maché, wood pulp or other substances, in order to prevent
warping or casting, to keep the pieces or their edges close together, and to prevent
them separating.
It consists of either flat circular or elliptical discs or wafers, or of flat straight keys
er circular straight shanked keys or dowells made with barbed flanged or burred ends
or edges.
These discs or keys are to be made by stamping out of sheet or plate iron, zinc, or
galvanized iron or other metal, or to be cast in moulds in any metal, or to be made in
wood, papier-maché, wood pulp or other suitable substance.
These discs or keys are to be driven in, or to be inserted in grooves, or slots or
holes made in the edges or sides of the wood or other boards or blocks and the
adjoining board is then to be pressed or hammered on to the discs or keys till the boards

COMPLETE SPECIFICATION.
Improvements in Dowels for Joinery Purposes..
SIDNEY VIGERS, 18 Abingdon Street Westminster, London, Surveyor, 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 is an Invention for keying or tongueing together the joints in wood, floor
boards or blocks in panels, or pieces of wood in joinery, or packing cases, also the
joints in boards composed of paper, papier mache, wood pulp, or other substances, in
order to prevent warping or casting, to keep the pieces or their edges close together,
and to prevent the pieces separating from each other.
It consists of flat discs or wafers of either circular, elliptical, square, octagonal,
hexagonal, or other shapes, or of flat straight keys, or straight round shanked keys or
dowels made with barbed, flanged or burred ends or edges. These discs or keys are
to be made by being stamped out of sheet or plate iron, zinc, galvanized iron, brass,
or other metal, or to be cast in moulds in any metal, or to be made in wood, papier
mache, wood pulp or other suitable substance."
These discs or keys are to be driven in, or to be inserted in grooves, slots or holes,
made in the edges or sides of the wood, or other boards, or blocks, and the adjoining
board is then to be pressed or hammered on to the discs or keys till the boards or
blocks are driven home, or are close together, when the joint is made.

page_text: The flat keys discs or dowels are also to be pierced with holes through their centres,
for the purpose of inserting a nail or screw, which is to be driven into the floor or
bed on which the block, parquet, or boarded floor is laid, for the purpose of holding
or tieing down the blocks, parquet, or hoards of the floor to the foundation, and to
prevent them working loose, chattering, or separating.
If this foundation be of concrete, stone or other hard materials, bonding blocks of
wood, tough concrete, or other substance which will hold nails or screws, are to be
inserted in the foundation at intervals or in rows, and the nails or screws driven
therein, as shewn on
plate 1.
In the case of flooring boards a ✓ shaped or splayed
groove is to be worked in the edges of both, and a rebate on the edge of one, to allow
space for the nails or screws, and the undersides of the disc or key are to be
cbamfered or splayed to fit the grooves, so as to draw the disc up tightly, when the
boards are cramped or pressed together.
Various applications of these keys or dowels are shewn in Drawings attached
.hereto.
1st. For wood block floors, parquetry, or straight board floors, as shewn on Plate I
and on Plate II marked A. B. C. D. E. and L.
2nd. For joints in joinery as shewn on Plate II marked F. G. H. I. J. and K.
3rd. Various forms of keys and discs.
Having now particularly described and ascertained the nature of my said Inven
tion, and in what manner the same is to be performed, I declare that I am aware
that it has been proposed to use unbarbed pins, plugs or dowels in jointing wood block
flooring and that it has also been proposed to employ bonding blocks in similar
flooring and I wish it to be understood that I make no claim at large to such arrange-
ments, but what I claim is.
1st. A new form of barbed or disc key, dowel or tongue for making joints as
described above.
2nd. A new system of laying wood block and other floors, with these discs or
keys as shewn in Drawings deposited herewith, and with further suitable modifica-
tions.
3rd. A new self-fixing barbed key for driving into wood or other soft substances
to fix two or more pieces together, without making grooves or holes.
Dated this 7th day of March 1890.

Applicant.
