page_text: LETTERS PATENT to Thomas Lovell Preston, of Birmingham, in the
County of Warwick, Machinist, and Thomas Lloyd, of Birmingham,
aforesaid, Brassfounder, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF METALLIC BEDSTEADS, CHAIRS, AND COUCHES, AND OTHER
ADEL DOOR FIEN MANDAGMID
"
PROVISIONAL SPECIFICATION left by the said Thomas Lovell Preston
and Thomas Lloyd at the Office of the Commissioners of Patents, with
their Petition, on the 18th December 1860.
We, THOMAS LOVELL PRESTON, of Birmingham, in the County of Warwick,
Machinist, and THOMAS LLOYD, of Birmingham, aforesaid, Brassfounder, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF METALLIC BEDSTEADS, CHAIRS, AND COUCHES, AND OTHER ARTICLES
OF LIKE MANUFACTURE," to be as follows:-
Our Invention consists firstly, of the following method of constructing the
corner joints of metallic bedsteads and other articles, in which the said
corner joints are or may be used. The said corner joints effect the junction;
of the vertical pillars with the horizontal rails of angle iron constituting the
sides of the bedstead or other article. On two of the vertical sides of the
corner block, which is fixed to the vertical pillar, we form by casting circular

page_text: projecting discs, having a projecting tongue on their lower edge, the said
discs and tongues standing out from the sides of the block, from one quarter
to half an inch. On the ends of the blocks cast on the bars of angle iron
recesses are made corresponding in form and size with the projections on the
corner blocks; screwed pins fixed in the faces of the said discs, but by preference
not concentric therewith, pass through corresponding holes in the rail blocks,
and screwed nuts on the said screwed pins bind the parts firmly together.
We sometimes use the method of joining described, with only one of the
two rails of angle iron joined to each pillar block, the said pillar block being cast
upon the end of the other rail of angle iron; we sometimes fix the screws in
the blocks on the ends of the angle iron instead of in the pillar block. In
this case we pass the said screws through the pillar block and secure them
by screw nuts on the other side.
Our Invention consists, secondly, of the following method of connecting the
horizontal rods, forming the tester frame of metallic bedsteads with the pillars,
which method of construction is also applicable to the foot rail of French and
other bedsteads, and also to metallic sofas and other articles of like manu-
facture. In the top of each vertical pillar, we make a hole in the axis of the
said pillar, and on the ends of the horizontal rods or the rods connecting the
said-pillars, we make or affix pins of a size-suitable to engage in the holes
in the pillars. By dropping the said pins into the said holes, the said rods
are secured to the said pillars. This method of connection is also applicable
to the cornices of metallic bedsteads.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Lovell Preston and Thomas Lloyd, in the Great Seal 2
Patent Office on the 17th June 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
LOVELL PRESTON, of Birmingham, in the County of Warwick, Machinist, and.
THOMAS LLOYD, of Birmingham aforesaid, Brassfounder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters.
Patent, bearing date the Eighteenth day of December, in the year of our
Lord One thousand- eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, .the.
said Thomas Lovell Preston and Thomas Lloyd, Her. special licence that we,..
the said Thomas Lovell Preston and Thomas Lloyd, our executors, admini-.3
strators, and assigns, or such others as we, the said Thomas Lovell Preston.

page_text: and Thomas Lloyd, our 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, exer-
cise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF METALLIC BEDSTEADS, CHAIRS, AND COUCHES, AND OTHER
ARTICLES OF LIKE MANUFACTURE," upon the condition (amongst others) that
we, the said Thomas Lovell Preston and Thomas Lloyd, our executors or
administrators, by an instrument in writing under our or their hands and
seals, or under the hand and seal of one of us or them 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 we, the said Thomas Lovell Preston and Thomas
Lloyd, 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:-
Our Invention consists firstly, of the improvements herein-after described
and illustrated in Figures 1, 2, 3, 4, 5, and 6, of the accompanying Drawing,
of constructing the corner joints of metallic bedsteads and other articles, in
which corner joints are or may be used. The said corner joints effect the
junction of the vertical pillars with the horizontal rails of angle or other bar
iron, which constitute the sides and ends of the bedstead or other article.
Figure 1 represents in plan a corner block made according to our Invention,
and Figure 2 represents in elevation the said corner block combined with a
block on the end of a horizontal rail, the two parts constituting a corner joint.
Figure 3 represents in vertical section the parts shewn in Figure 2, and Figure 4
represents in vertical section the horizontal rail and the block cast thereon.
On two of the vertical sides of the corner block a fixed on the vertical pillar of
the bedstead we form by casting projecting discs 6, the said discs being slightly
conical on their edge, as seen in Figure 1; each of the said dises b has a
projecting tongue c, on its lower edge, or two of the said tongues may be
employed on different parts of the edges of the discs. The said discs b, and
tongues c, stand out from the sides of the block from one quarter of an inch
to half an inch. We cast on the ends of the bars of angle iron e, blocks d,
having recesses fin their ends, the said recesses f being the counterpart in
form and size of the projections and tongues b, c; on the corner blocks a
screwed pins g are fixed in the corner blocks a, the said pins being by

page_text: preference not concentric with the projections b (as seen in Figures 1 and 2);
and holes are made in the blocks d on the angle iron e, through which
said holes the screwed pins 9 pass when the parts a and d are fitted together.
The said screwed pins 9 may be fixed in the blocks a by inserting the said
pins in the moulds in which the said blocks are cast and casting the said
blocks on the said pins. In putting the parts of the joint together the block d
is passed upon the screwed pin g into the position shewn in Figures 2 and
3, and a screwed nut i being screwed on the end of the screwed pin g.the
parts a and d are firmly secured together. The method described of joining
the blocks a and d together may be employed with one only of the two rails
of angle iron joined to each pillar block, that is, the pillar block a may be
cast on one of the rails of angle iron, and the other rail may be joined to the
pillar block in the manner described. Instead of fixing the screwed pins g
in the pillar block a the said screwed pins may be fixed in the block on
the end of the rail of angle iron, and passed through the pillar block..
Figure 5 represents this modification in plan; k is the corner block, and la
rail of angle iron. In the block cast on the end of the rail the screwed
pin m is fixed, the said pin m being fixed in the middle of the said block.
-The-end-of-the-rail--with-the-screwed-pin-m-fixed-thereto-is-shewn-separately-
in Figure 6. The screwed pin m is passed through a hole in the block k;
and secured by the screwed nut n. The other rail or rod o may be fixed
in the block k by casting as herein-before described. The improvement
described and represented in Figures 5 and 6 is especially applicable to
chairs.
Our Invention consists, secondly, of the improvement or improvements
herein-after described and illustrated in Figures 7, 8, and 9 of the accompanying
Drawing, in connecting the horizontal rods, forming the tester frames of
metallic bedsteads, with the pillars of the said bedsteads, which improvement
or improvements are also applicable to the head and foot rails of French
bedsteads and to the foot rails of other bedsteads, and also to metallic sofas
and other articles of like manufacture, as well as to connecting the cornices
of metallic bedsteads to the said bedsteads. Figure 7 represents in elevation
part of the head or foot rail of a French bedstead connected with the pillar
of the bedstead according to this part of our Invention. In the top of each
of the vertical pillars, one of which is marked p in Figure 7 we make a hole
in the axis of the said pillar. Or where the pillar is made of a hollow tube,
we fix a smaller tube 9 therein and concentric therewith. On the end of the
head or foot rail r, connecting two of the pillars p together, we make or affix
pins s of a size suitable to engage in the holes or in the small tubes q in the

page_text: pillars p. By inserting the pins s into the holes or tubes q, the head or foot
rail r is secured to the pillars. The tube q may either be taper and elliptical
in cross section, as represented in Figure 8, or be taper and cylindrical in
cross section, as represented in Figure 9; or the said tube 9 may be made
without tapering. In Figure 7 we have only represented part of a head or
foot rail connected at one of its ends to a pillar p, the other end of the said.
head or foot rail being connected in a similar manner to another pillar. The
said head or foot rail may either be ornamented, as represented in Figure 7,
or consist of plain horizontal rods, our method of connecting being applicable
both to plain and ornamental head and foot rails and other like articles.
Having now described the nature of our Invention, and the manner of
carrying the same into effect, we wish it to be understood that we do not
limit ourselves to the precise details herein described, as the same may be
varied without departing from the nature of our Invention, but we claim as
our Invention, firstly, the improvements in the corner joints of metallic
bedsteads, chairs and couches, and other articles of like manufacture herein-
before described and represented in Figures 1, 2, 3, 4, 5, and 6 of the
accompanying Drawing.
Secondly, the improvement or improvements herein-before described and
illustrated in Figures 7, 8, and 9, of the accompanying Drawing in connecting
the tester frames and cornices of metallic bedsteads, and the head and foot
rails of French bedsteads, and the foot rails of other bedsteads with the pillars
of the said bedsteads, and the application of the said improvement or improve-
ments to the connecting of such other parts of articles of metallic furniture
as the said improvement or improvements are or may be applicable to.
In witness whereof, we, the said Thomas Lovell Preston, and Thomas
Lloyd, have hereunto set our hands and seals, this Fifteenth day of
June, in the year of our Lord One thousand eight hundred and
sixty-one.
