Sealed the 16th April 1853, and dated the 4th February 1853.
PROVISIONAL SPECIFICATION left by the said William Brown
at the Office of the Commissioners of Patents, with his Petition,
on the 4th February 1853.
I, WILLIAM BROWN, of Birmingham, in the County of Warwick,
Clerk of Works, do hereby declare the nature of the said Invention
for "AN IMPROVEMENT OR IMPROVEMENTS IN. THE CONSTRUCTION OF METALLIC
BEDSTEADS" to be as follows:-
My Invention consists in a new or improved method of connecting
the angle iron of which the sides.and ends of metallic bedsteads are
made to the corner pieces or blocks which are fixed on the pillars
of the said bedstead...
Fig. 1, represents in plan a corner block constructed according
to my Invention with one of. the rails connected.therewith. In the
said corner block I make on two adjacent sides a taper groove of the
form represented at a, Figs. 1 and 2, and a depression or cavity b;

page_text: the grove a extending from the top to nearly the bottom of the
said block, and the depression or cavity 6 extending to the depth
indicated by the dotted lines b, Fig. 2. The end of the angle iron
is fashioned as represented in the several Figures; that is to say, the
edge of the vertical side of the angle iron is turned at right angles
so as to fit the groove a, and a projection on the horizontal end of
the angle iron enters the depression b. c, Fig. 3, represents the
edge which enters the groove a; and d; the projection which enters
the depression b. The ends of the said angle iron are strengthened,
as shown in the Drawing, in order to make the junction more firm.

SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said William Brown in the Great Seal
Patent Office on the 29th July 1853..
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM BROWN, of Birmingham, in the County of Warwick, Clerk
of Works, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of February, 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 William Brown,
Her special license that I, the said William Brown, my executors,
'administrators, and assigns, or such others as I, the said William
Brown, 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 IMPROVEMENT OR IMPROVEMENTS IN THE CONSTRUC-
TION OF METALLIC BEDSTEADS," upon the condition (amongst others)
that I, the said William Brown, 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

Patent Office within six calendar months next and immediately.
after the date of the said Letters Patent.

NOW KNOW YE, that I, the said William Brown, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being.
had to the Drawing hereunto annexed, and to the figures and letters
marked thereon, that is to say:
-
My Invention consists in a new or improved method of connecting
the angle iron of which the sides and ends of metallic bedsteads are
made to the corner pieces or blocks which are fixed on the pillars of
the said bedsteads, which said method consists in so fashioning the
ends of the said angle iron that the said ends may engage in the
corner pieces or blocks without the use of the dovetail or other piece
usually affixed by casting or otherwise on the said angle iron.
Figure 1, represents in plan a corner block and rail connected there-
with, the same being constructed according to iny Invention and
Figure 2, represents the said corner block separately in elevation. In
the said corner blocks a, I make on two adjacent sides a taper groove
b, and a depression or cavity c; the said groove b extending nearly to
the bottom of the said block, and the cavity c extending to the depth
indicated by the dotted lines c, in Figure 2. The end of the angle iron
is formed as represented in Figures 1 and 3; that is to say, the end
of the vertical side of the said angle iron is turned at right angles,
so as to form the piece d, Figure 3, which fits the groove b, Figures
1 and 2; and a portion of the horizontal side of the angle iron is
turned down, so as to form the projection e, which fits the depres-
sion c, Figures 1 and 2: Figures 4, 5, and 6, represent another
method of carrying my Invention into effect; Figure 4, represent-
ing a plan of a corner block with one rail in its place; Figure 5, repre-
sents the said corner block in elevation without the rail; and Figure
6, represents the under side of the rail. The corner piece or block
has the groove f, in which the vertical turned side g of the rail h, see
Figure 6, fits, and the recess i in which the projection k engages,

page_text: the said projection k, being formed as seen in the view of the
under side of the rail, Figure 6, by cutting from the horizontal face
of the angle iron a semi-circular or other formed piece at k¹. When
great strength is required I form the piece d, Figure 3, and pro-
jection e, Figure 3, of the form represented in Figure 7; that is to
say, of a cylindrical or slightly conical form, as represented at e
and d¹ in the said Figure 7. I give the said form to the said parts
by forging or pressing or any other suitable process.
Having now described the nature of my said Invention, and the
manner in which the same is to be performed, I wish it to be under-
stood that I do not limit myself to the precise methods of carrying
iny Invention into effect herein described and illustrated in the ac-
companying Drawing, as the same may be varied without departing
from the nature of my said Invention; but I claim the constructing
(by any convenient process) of a projection or dovetail on and of
the same substance as the angle iron forming the framing of metallic
bedsteads for the purpose of connecting the said angle iron with the
corner pieces or blocks of the said metallic bedsteads, in place of the
dovetail usually cast on or otherwise formed independently of the
said angle iron.
In witness whereof, I, the said William Brown, have hereunto
set my hand and seal, this Twenty-sixth day of July, in
the year of our Lord One thousand eight hundred and
fifty-throa
Witness,
GEORGE SHAW.
WILLIAM BROWN. (L.S.)
