Improvements in the Construction of Sides for Metallic Bedsteads.
JOSIAH BROOKES and HENRY JAMES BROOKES both of The Cape Bedstead Works
Smethwick in the County of Stafford, Bedstead Manufacturers, and GEORGE HIGGS
92 Bearwood Road also of Smethwick aforesaid, Manager do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to strengthen the sides of metallic bedsteads.
The sides are made of angle iron with the usual dovetail joint cast at each end.
When casting the dovetail joints upon the angle irons a small rod of iron, generally
round or of any convenient section, is laid in the moulds, and the melted iron is
poured round the ends of the rod and the angle iron at the same time, thus securing
them together. This iron rod is cast just underneath the upper side of the angle
which is the horizontal side when fixed in the bedstead. Before the iron rod is
cast into the dovetails there is threaded on to it a small piece of iron, called a
strut or bracket, which is reduced in size, or shouldered down, at the opposite end
to that which slides upon the iron rod. This smaller end fits into a corresponding
hole in the upper side of the angle, and as the strut or bracket is forced into the
hole in the angle, it is obvious that it puts into tension both the angle and the
rod, the latter being cambered considerably out of the straight.
This strut or
bracket is secured either by riveting it into the angle, or by any other convenient
method. The sides thus constructed are much stronger than the ordinary angle iron
sides, while the cost is not materially increased.

Improvements in the Construction of Sides for Metallic Bedsteads.
JOSIAH BROOKES and HENRY JAMES BROOKES both of The Cape Bedstead Works
Smethwick in the County of Stafford Bedstead Manufacturers and GEORGE HIGGS
92 Bearwood Road also of Smethwick aforesaid, Manager 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 statenient :-
The object of this invention is to strengthen the sides of metallic bedsteads.
The sides are made of angle iron with the usual dovetail joint cast at each end.
When casting the dovetail joints upon the angle irons a small rod of iron generally
round, or of any convenient section, is laid in the moulds and the melted iron is
poured round the ends of the rod and the angle iron at the same time, thus securing
them together. This iron rod is cast just underneath the upper side of the angle,
which is the horizontal side when fixed in the bedstead. Before the iron rod is cast
into the dovetails there is threaded on to it a small piece of iron called a strut or
bracket, which is reduced in size or shouldered down at the opposite end to that
which slides upon the iron rod. This small end fits into a corresponding hole
in the upper side of the angle, and as the strut or bracket is forced into the hole
in the angle, it is obvious that it puts into tension both the angle and the rod, the
latter being cambered considerably out of the straight. This strut or bracket is
secured either by riveting it into the angle, or by any other convenient method. The
sides thus constructed are much stronger than the ordinary angle iron sides, while
the cost is not materially increased.

page_text: The details of the invention are illustrated by the accompanying drawings, Fig. 1
shows the side of the bedstead a being the angle iron, 6 the cast iron dovetail joints,
c the rod of iron. d the strut or bracket which is on the rod c, and is shewn hanging
loosely on the said rod ready to be reversed and sprung into its position in angle
iron, as shewn in Fig. 2, in which the respective parts are as shewn in Fig. 1, except
that the strut or bracket d is there shewn fixed into its proper position in the angle
iron.
It is obvious that the strut or bracket d may be fixed into its position in the angle
iron before the ends of the rod c are cast into the dovetail joints, since the con-
traction of the cast iron in the dovetail joints would put the rod and the angle
iron into tension to some extent; but we prefer that the strut or bracket shall be
sprung into position after the rod is cast, since the tension and consequently the
rigidity of the side is thereby materially increased.
The strut or bracket may also be varied in shape, and when required may be of
cast iron, being chilled or cast on the rod, and the same operation of casting securing
it to the angle iron, the tools or chills for such operation, being similar to what
are generally used for such operations in the metallic bedstead trade.
Any section of iron can be used for the rod c, the ends of which need not
necessarily be cast into the dovetail joints as shewn in drawings, but may be secured
to the angle iron or dovetail joints by any convenient method, but we prefer to cast
them as described, since it is the cheapest and best method of securing them.
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
1. Making sides of beadsteads with strengthening rods c or any
thereof without departing from the principle of the invention.
2. The use of the strut or bracket d in making sides of bedsteads or any
thereof without departing from the principle of the invention.
