IMPROVEMENTS IN THE CONSTRUCTION OR CARINET SORA AND CHAIR BEDSTEADS
Year: 1865

page_text: LETTERS PATENT to Andrew Sharp, of Glasgow, in the County of Lanark,
North Britain, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OR CARINET SORA AND CHAIR BEDSTEADS."
Sealed the 13th June 1865, and dated the 20th February 1865..
PROVISIONAL SPECIFICATION left by the said Andrew Sharp at the Office
of the Commissioners of Patents, with his Petition, on the 20th February.
1865.
I, ANDREW SHARP, of Glasgow, in the County of Lanark, North Britain,
do hereby declare the nature of the said Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF CABINET, SOFA, AND CHAIR BEDSTEADS," to be as follows, that
is to say:
This Invention relates to certain improvements in the construction of
cabinet, sofa, and chair bedsteads, and consists chiefly in joining together the
framework of the bedstead proper by cast-iron binders in lieu of drilling holes
in some of the bars and uniting the bars contiguous thereto by riveting.
According to one method of carrying out this Invention, when any two
pieces of the framework are placed in the position which they are intended to
permanently occupy relatively to one another, the portions of the two parts to
be joined are placed within a chill and the metal is run into it, which, as soon
as it sets, embraces those portions on which it is cast.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANDREW
SHARP, of Glasgow, in the County of Lanark, North Britain, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of February, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Andrew Sharp, Her special license that I, the said Andrew Sharp, my executors,
administrators, and assigns, or such others as I the said Andrew Sharp, my
executors, administrators, or 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 CABINET,
SOFA, AND CHAIR BEDSTEADS," upon the condition (amongst others) that I, the
said Andrew Sharp, 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 Andrew Sharp, 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, reference being had to the accompanying Drawings, and to the
letters and figures marked thereon, that is to say:-
My said Invention relates to certain improvements in the construction of
cabinet, sofa, and chair bedsteads, and consists chiefly in joining together the
framework of the bedstead proper by cast-iron binders in lieu of drilling holes
in some of the bars and uniting the bars contiguous thereto by riveting.
According to one method of carrying out this Invention, when any two
pieces of the framework are placed in the position which they are intended to
permanently occupy relatively to one another, the portions of the two parts to
be joined are placed within a chill and the metal is run into it, which, as soon
as it sets, embraces those portions on which it is cast.
And in order that my said Invention may be properly understood I shall

page_text: now proceed more particularly to describe the system, mode, or manner in or
under which the same is or may be used or practically carried into effect,.
reference being had to the several Figures upon the explanatory Sheet of
Drawings which I have hereunto appended, and in which similar parts are
indicated by corresponding letters of reference, that is to say:-
Figure 1 is a side elevation, and Figure 2 a plan of a cabinet bedstead
constructed in accordance with my Invention, Figure 3 being an enlarged
detailed view of the joint, and will herein-after be more fully referred to
On referring to Figures 1 and 2 it will be observed that the opposite sides
of the framework, marked A and B, are connected together by means of the
cross bars C, C¹, C, C³, C, C, C, C7; these cross bars are attached to the
longitudinal side framing bars by means of the metal clamps D, which in
themselves form the chief part of this Invention. The central legs E and F
are also connected together near their lower ends by the cross bars G and
clamps H, in a similar manner to the framework of the bedstead proper.
The mode of carrying out this system of joining together the parts of bedsteads
may be effected in various ways; for instance, the end of the cross bars C, C¹,
etc. may be dovetailed, as shown at Figure 3, so that when the clamp D is
cast over the parts to be joined together this may, on contracting, tightly
grasp the cross bar. Instead of dovetailing the end a hole may be drilled in
it, so that the metal, when cast over the joint, shall run through it, thus
forming a kind of pin joint; or instead of this a pin or pins may be fastened
into the ends of the cross bars. Besides forming the bedstead proper in the
manner herein-before described, I prefer, also, to attach the two ornamental
ends I and K in the same manner as shown particularly at Figure 1.
In carrying out this Invention it is preferred to employ chills formed with
suitable cavities to receive the parts of the bedstead to be joined together, and
cut with any desired ornamental device for imparting a light and attractive
appearance to the clamps D. The clamps may be cast on separately, but
I consider it preferable to employ large chills to hold each division of the
framework at once; by this means the bedsteads are much more speedily,
and therefore more economically constructed than by any preceeding method.
In lieu of using chills, the clamps may be cast over in sand or loam, altho
I prefer to employ chills.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or practically
carried into effect, I would observe in conclusion that what I consider to be novel
and original, and therefore claim as the Invention secured to me by the berein-

and chair bedsteads by means of attaching their several parts together by cast.
metal clamps, substantially as herein-beforé described.
In witness whereof, I, the said Andrew Sharp have hereunto set my hand
and seal, this Fifteenth day of August, One thousand eight hundred
and sixty-five.
ANDREW SHARP. (L.S.)
