AN IMPROVED JOINT FOR CABINET MAKING, CARPENTRY,' AND OTHER CONSTRUCTIVE PURPOSES
Year: 1859

page_text: LETTERS PATENT to Joseph Bine, of Clerkenwell, in the County of
Middlesex, Fancy Cabinet Manufacturer, for the Invention of "AN
PROVISIONAL SPECIFICATION- left by the said Joseph Hine at the
Office of the Commissioners of Patents, with his Petition, on the
26th February 1859.
I, JOSEPH HINE, of Clerkenwell, in the County of Middlesex, Fancy Cabinet
Manufacturer, do hereby. declare the nature of the! said Invention for "AN
IMPROVED JOINT FOR CABINET MAKING, CARPENTRY,' AND OTHER CONSTRUCTIVE
PURPOSES," to be as follows:-
This improved joint, applicable to all purposes where a rectangular or
other angular joint, a parallel flush joint, or a sliding joint is required, and
may be made in wood, metal, slate, stone, or other material. The joint
consists of a double tongue and double groove, such tongues and grooves
being at right angles to each other.
In the annexed Drawing, Figure 1 represents the joint as used for
rectangular work for cabinet or other purposes.
The principal feature in this joint consists in the two feathers or..
tongues a, a, in the piece A at right angles to each other; and the two.
[Price 8d.]

page_text: corresponding grooves b, b, in the piece B. It will be seen from the peculiar
construction of this joint that it is self-supporting and self-binding, and when
put together and glued or otherwise cemented, requires no binding or other
securing, as it cannot move in any direction except sliding in the direction of
the grooves and feathers. Where a parallel flush joint is required, as for
flooring and other purposes, the form of the joint is slightly altered, as shown
in Figure 2; but where a joint is not required to be flush, whether fixed or
sliding, it may be in the same form as Figure 1, and put together in the
manner shown in Figure 3.
This improved joint is cut or formed by means of two circular saws of a
similar diameter, revolving on the same shaft, the saws being the thickness
of the required grooves, and divided by a washer of similar thickness; or
the same effect may be produced by the use of planes or cutters.
By the use of this joint, so. constructed, not only a considerable economy
both in labor and time is effected, but also the joint is much less expensive
and stronger than the joints hitherto employed.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent
and of an Order of the Lord Chancellor, by the said Joseph Hine in
the Great Seal Patent Office on the 2nd September 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
HINE, of Clerkenwell, in the County of Middlesex, Fancy Cabinet Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters'
Patent; bearing date the Twenty-sixth day of February, in the year; of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Hine, Her special licence that I, the said Joseph Hine,
my executors, administrators, and assigns, or such others as I, the said
Joseph Hine, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
" AN IMPROVED JOINT FOR CABINET MAKING, CARPENTRY, AND OTHER CONSTRUCTIVE
PURPOSES," upon the condition (amongst others) that I, the said Joseph Hiue,
my executors or administrators, by an instrument in writing under my, or,

page_text: their, or one of their hands and seals, should particularly describe and ascer-
tain the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent Office
on or before the Second day of September, One thousand eight hundred
and fifty-nine.
NOW KNOW YE, that I, the said Joseph Hine, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and the Drawings therein referred to (that is to say)
--
My Invention, which has reference to an improved form and construction
of joint applicable for the general purposes of cabinet making and carpentry,
as also for various other purposes of construction, consists of an arrangement.
of grooves or tongues formed upon the edges of the several articles to be
jointed together or otherwise, so as to obtain a more permanent fixed or
sliding joint than hitherto, the said joint be employed in lieu of teuons and
mortices, as also dovetails for jointing together the sides, tops, and bottoms
of cubical and quadrilateral forms or figures, such as boxes, desks, or tanks, as
also for doors, window sashes, partitions, front and side rails, and legs of
chairs, and in place of ploughing and tongueing, for joining or uniting
window frames, shutters, frames of tables, the upper and lower styles of
doors, or any or all of the various articles to which the same is or may be
applicable, either in wood, metal, or otherwise.
But in order that this my said Invention may be more fully understood
and readily carried into effect, I now proceed to describe it by the aid of
the accompanying Drawings, reference being had to the letters and figures
thereon marked (that is to say):-
Fig. 1 represents, an end elevation of the tongues and grooves, showing
the mode of forming my improved plane surface joint; Fig. 2, the same,
united or secured; Figs. 3 and 4, corresponding views of an angle joint of
the same principle of construction; and Figs. 5 and 6, a plan and sectional
elevation of a sliding joint. In each Figure the same letters of reference
denote similar corresponding parts.
A, A, the wood, metal, or otherwise to be joined; B, B, the joint formed
of right-angular double tongues and grooves, fitting into each other, as
represented; C, C, an article constructed according to my Invention.
In conclusion to the foregoing description, I would here briefly note that
the grooves and tongues may be formed by the employment of circular
saws, planes, cutters, or other suitable slotting tools or instruments, and the
said joints glued, cemented, or otherwise secured by any of the usual means

page_text: Having now fully described and ascertained the nature of this my said
Invention, and the manner in which the same is to be performed, I would
have it clearly understood that I do not intend to confine myself to the precise
details herein-before described, asthe same might be varied without departing
from the general principle of this my said Invention; but that which I do
claim as new and of my said Invention is, the construction and employment
of right-angular double-tongued and grooved joints in the manner and for
the purposes herein-before set forth and described.
In witness whereof, I, the said Joseph Hine, have hereunto set my
hand and seal, this Second day of September aforesaid.
