IMPROVEMENTS IN WOOD FLOORING, CEILINGS AND DADOS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I ALFRED PUTNEY of Baltic Wharf Paddington in the county of Middlesex
Timber Merchant do hereby declare the nature of the said invention for
"IMPROVEMENTS IN WOOD FLOORING, CEILINGS AND DADOS " to be as follows:-
This invention relates to improvements in the joints of that class of wood
flooring, ceilings and dados known as nail-less, that is to say, in which no nails
appear on the surface.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawing in which figures 1 and 2 represent
sections of portions of flooring shewing my improvements in the joints therefor;
figure 3, section shewing the method of jointing the boards to form dados, ceilings
and the like.
In figures 1, and 2, a, a¹, are the boards one edge of each of which is formed with
a tongue b, which tongue in figure 1 is shewn with an inclined upper surface c, and
in figure 2, it is shown formed horizontal. The edge of the board above the tongue
is formed with an incline d, inwardly from the upper surface the other edge of
each board is formed with a groove e, and an incline f, corresponding with the
incline d.
By this arrangement one board a, is placed in position and is fixed by a nail 9.
driven from the inclined surface of the tongue through the board and into the
joist; the grooved edge of the next board a¹, is then brought into position against
the board a, the groove e, fitting over the tongue b, and the inclined surface f,
against and practically under the incline d, whereby a good joint between the two
inclined surfaces d, and f, is obtained and the edge of the board having the inclinef,
is prevented from rising or springing as it is hold down by the inclined surface d.
In the arrangement for ceilings and dados shewn in figure 3, one edge of the
board a', is formed with a groove e, and inclined surface f, as shewn in figure 1,
but on the opposite edge of the board a, the surface d, is inclined in the opposite
direction to the surface d, of the board a, in figure 1, whereby a V-joint is obtained
when two boards are brought together edgewise.

I ALFRED PUTNEY of Baltic Wharf, Paddington in the county of Middlesex,
Timber Merchant do hereby declare the nature of the said invention for
"IMPROVEMENTS IN WOOD FLOORING, CEILINGS AND DADOS" 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 improvements in the joints of that class of wood
flooring, ceilings and dados known as nail-less, that is to say in which no nails
appear on the surface.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawing in which figures 1, and 2, represent
sections of portions of flooring shewing my improvements in the joints therefor;
figure 3, section shewing the method of jointing the boards to form dados, ceilings
and the like.
In figures 1, and 2, a, a, are the boards one edge of each of which is formed with
a tongue b, which tongue in figure 1 is shewn with an inclined upper surface c, and
in figure 2, it is shewn formed horizontal. The edge of the board above the tongue
is formed with an incline d, inwardly from the upper surface the other edge of
each board is formed with a groove e, and an incline f, corresponding with the
incline d.
By this arrangement one board a, is placed in position and is fixed by a nail g,
driven from the inclined surface of the tongue through the board and into the
joist; the grooved edge of the next board a¹, is then brought into position against
the board a, the groove e, fitting over the tongue b, and the inclined surface f,
against and practically under the incline d, whereby a good joint between the
two inclined surfaces d, and f, is obtained and the edge of the board having the
incline, is prevented from rising or springing as it is held down by the inclined
surface d.
In the arrangement for ceilings and dados shewn in figure 3, one edge of the
board a¹, is formed with a groove e, and inclined surface f, as shewn in figure 1,
but on the opposite edge of the board a, the surface d, is inclined in the opposite
direction to the surface d, of the board a, in figure 1, whereby a V-joint is obtained
when two boards are brought together edgewise.
Having now particularly described and acertained the nature of my said
invention and in what, manner the same is to be performed I declare that what
I claim is
(1) The described improvements in wood flooring consisting in forming one edge
of the boards with a tongue b, and inwardly inclined surface d, adapted to take

page_text: into and against the groove e, and inclined surface f, on the edge of the next board
as and for the purposes set forth and represented in figures 1 and 2, of the
drawing.
(2) The described joint for ceilings and dados as represented in figure 3 of the
accompanying drawing.
