Year: 1853

page_text: LETTERS PATENT to Jolm Wright, of Camberwell, in the County
of Surrey, Engineer, for the Invention of "IMPROVEMENTS IN THE
COSMEHAMION OF REDANG
Ti"
PROVISIONAL SPECIFICATION left by the said John Wright at
the Office of the Commissioners of Patents, with his Petition,
on the 8th March 1853.
I, JOHN WRIGHT, of Camberwell, in the County of Surrey, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF BEDSTEADS, AND OTHER FRAMES" to be as
follows:-
This Invention consists of constructing the uprights or posts of
bedsteads, and other frames, each of two parts capable of being con-
nected by screw and nut passing up the centre. The side and end or
other rails are cach made with inclined ends, and each with a portion
of a circular groove on the upper and under sides thereof. The two
parts of each of the posts or uprights have, on the ends which are
moved towards each other (by the screw and nut), corresponding
circular projections, with inclined sides, so that in the act of their

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Wright, in the Great Seal Patent Office,
on the 8th September 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN WRIGHT, of Camberwell, in the County of Surrey, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of March, in the year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Wright, Her special licence that I, the
said John Wright, my executors, administrators, and assigns, or such
others as I, the said John Wright, 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 "IMPROVEMENTS IN THE CONSTRUCTION OF
BEDSTEADS AND OTHER FRAMES," upon the condition (amongst others)
that I, the said John Wright, by an instrument in writing under my
hand and seal, should particularly describe and ascertain 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 within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Wright, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):
This Invention consists of constructing the uprights or posts of
bedsteads, and other frames, each of two parts capable of being con-

page_text: nected by screw and nut passing up the centre. The side and end or
other rails are each made with inclined ends, and each with a portion
of a circular groove on the upper and under sides thereof. The two
parts of each of the posts or uprights have, on the ends which are
moved towards each other by the screw and nut, corresponding circular
projections with inclined sides, so that, in the act of their being drawn
together, they will draw the two rails together, and thus hold all parts
securely.
Having thus stated the nature of my Invention, I will now proceed
to describe the same more particularly, aided by the drawing hereunto
annexed, in the various figures of which the same letters in all instances
indicate the same parts.
DESCRIPTION OF THE DRAWING.
Figure 1, is a plan, and Figure 2, a section, of rails of a bedstead
connected and held together in accordance with my Invention; Figure 3,
is a transverse section taken through 1, 1, in Figure 2; Figure 4, shows
a plan and section of rails, or parts of a frame; and Figure 5, shows
a manner of connecting the frames of bedsteads by the parts forming
the posts, which, though very similar to the method shown by Figures
1, and 2, is nevertheless somewhat different, and may, for some
purposes, be preferable. a, a, are the rails composing the frame, having
each at their ends a semicircular groove a', a', formed therein, as also
a semicircular opening a², a², for the passage through of the screw b,
by which and the nuts c, c', (in the mortices d³, d, of the parts d, d,
which form the posts,) they are drawn together; the parts d, d', which
form the posts, have each formed on them a ring or projection d², d²,
corresponding with the grooves a', a', formed in the rails a, a. The
parts are fixed together as follows:-The frames a, a, are placed in the
position shown by plan, Figure 1; the screw b, is then screwed into
the nut c', which is morticed into the lower portion d', of the posts;
then the upper portion d, of the post is to be placed on the other end
of the screw b, and turned, so that the end of the screw b, enters the
nut c, and, by continuing to turn that part of the post d, and holding
the part d', or (vice versa,) the circular projections d², d³, of the posts d,

page_text: enter the grooves a', a', of the rails, and the parts become firmly held
together. In Figures 4, and 5, it will be seen that the projections
,, instead of being formed on the parts d, d, are formed separately
therefrom, and only become fixed by the screwing of the nuts c, c', on
to the ends of the screw 6: the grooves a', a', and their corresponding
projections or rings d, d, are made taper or wedge shaped, in order
to draw the parts or rails a, a, the more tightly together.
Having thus described my Invention, and the manner of performing
the same, I would have it understood that I do not confine myself to
the exact details herein shown and described, so long as the pc-
culiarity of my Invention be retained; but what I claim is the
constructing the uprights or posts of bedsteads, and other frames, cach
of two parts capable of being connected by screw and nut passing up.
the centre, as herein de-cribed.
In witness whereof. I, the said John Wright, have hereunto set
my hand and seal, this Eighth day of September, in the year
of our Lord One thousand eight hundred and fifty-three.
JOHN WRIGHT. (L.S.)
Witness, FRED* HARRIS.
