Improvements in the Manufacture of, or Putting Together of Parts
of, Metallic Bedsteads, Cots, and other articles of a like
manufacture.
We, SAMUEL WILSON, THOMAS WILSON, and WILLIAM WILSON, trading
as Wilson Brothers, of Ledsam Street, in the City of Birmingham, Bedstead
Manufacturers, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to the manufacture of metallic articles, such as bedsteads,
cots and metallic furniture generally in a cheap and efficient manner.
Heretofore the better class of the said articles have had the tubes, or the tubular
parts comprehending the pillars, foot and end rails or framings and the like, made
from what is known in commerce as brazed or hard-soldered tubes, which are most
expensive when compared with the tubing which we intend to apply in lieu of the
said expensive tubing, as hereinafter described.
The solder of brazed tubing fuses only at a heat, a little less than the metal
itself, and in consequence of the particular method of manufacture, becomes
costly.
According to our invention, we make the said pillars and other hollow parts of
the said articles from open jointed tubing, (called in the trade "close joint tube")
which is soldered, or the joints thereof soldered or closed by soldering subsequent
to the casting of the pillar corners, and junction chills around parts of them.
Thus, in making up a bedstead, we take the necessary lengths of open-jointed
tubing, and lay the same in suitable moulds, and cast around parts of them, chills,
which by the contraction of the metal holds the opposite edges of the said joints
close to each other.
These joints are next cleaned, or oxidation removed, by the application of
ordinary known means.
Then the prepared open joints are soldered, with an alloy having a fusing point,
higher than the heat which is afterwards applied in the japanning or enamelling
stove.
Thus, after the open jointed tubes have been chilled together, and the joint
prepared, soldered and dressed by the removal of superfluous solder and residues,
the joint is made perfectly solid with the adjacent walls of the tubings, and on
japan or enamel being applied, and subsequently stoved, the joint part of the
tubings have the same finish and appearance as brazed or seamless tubings, and
at the same time possessing equal properties with the expensively produced
tubings.
In carrying out a modified form of our invention, we heat the article or the
tubes to a sufficient degree of heat to fuse a soft solder which has been placed,
together with a suitable flux, along the cleaned or prepared edges of the said open-
jointed tubes. We then dress the soldered joints, and apply the japan or enamel in
the usual way.
If the joint is required to be invisible, we apply a solder of the color, as near as
possible, of the metal of the tubes.
Figure 1 of the accompanying drawing represents a portion of a metallic bedstead
having open jointed metallic tubes used or employed in its construction.
Figure 2 represents a portion of the said bedstead upon an enlarged scale.
Figure 3 is a section upon the dotted lines A B Figure 3 before soldering, and
Figure 4 is a cross section of the same after soldering.
a is an open jointed tube, b is the joint thereof, and o is the soldered seam, while
d are the chills.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
First-The improvements in the manufacture of metallic bedsteads, or articles
of a like manufacture, making the same up from open-jointed or open-seamed
tubings, whose joints are soldered or filled up subsequent to the chilling or casting
process, as set forth.
Secondly-The improvements in the manufacture of metallic bedstends and
articles of a like manufacture, the employment of open-seamed tubings, whose
joints are closed by soft solder, or a solder fusible at a higher temperature than the
stoving point, after the cast corners and chills have been applied, as set forth.
