[Communicated from abroad by Leopold MAYER, of No. 6, Boulevard de Strasbourg,

Improvements in Metal Bedsteads.
I, HENRY HARINGTON LEIGH, Fel. Inst. P.A., Assoc. M. Inst. C.E., of No. 22,
Southampton Buildings, Chancery Lane, W., practising as Phillips & Leigh,
Engineers and Patent Agents, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in metal bedsteads, and has especial reference
to the method of adapting the sides to engage with the head and foot rails, and the
laths with the sides and rails.
In carrying it into effect I bolt a tenon to the end of the angle iron forming the
side.
One flange of the angle is longer than the other, and a recess is formed in the
piece in which the mortice is made, into which the projecting flange will fit when
the side is fixed.
The laths are made with hooked ends, and suitable slots are formed in the angle
irons to receive them.

Improvements in Metal Bedsteads.
I, HENRY HARINGTON LEIGH, Fel. Inst. P.A., Assoc. M. Inst. C.E., of No. 22,
Southampton Buildings, Chancery Lane, W., practising as Phillips & Leigh,
Engineers and Patent Agents, 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 :-
My invention relates to improvements in metal bedsteads, and in order that it may
be thoroughly understood I will now describe it in detail referring in so doing to
the accompanying drawings, which are to be taken as part of this specification and
read therewith.
According to the usual method of making metal bedsteads, the sides are joined to
the head and foot rails, or to the pillars, by tenons rivetted or bolted to the same.
This has proved itself both unsightly and costly, and like drawbacks characterise
the method hitherto practised of fixing the laths to the sides by devices rivetted or
bolted to the sides, and holes in which the hooks of the laths are engaged. A further
disadvantage of this method is that when the said devices are rivetted, the oscillations
produced by shocks to the bedstead produce a wear and tear tending to shear the
rivets off.
Fig. 1 is a half plan.
Fig. 2 is a side elevation.
Fig. 3 is a detail side elevation.
Fig. 4 is a plan corresponding therewith.
Fig. 5 is a detail side elevation of a modification.
Fig. 6 is a plan corresponding therewith.
Upon each pillar A, and making one piece with it, there is a tenon, B, in which
there is made through half its thickness a recess of a dovetail or other suitable shape.
This recess
adapted to receive the side, C, the end of which is formed to correspond
with the said recess, so as to bed therein exactly. so that both have one CommoD

page_text: external surface. A bolt, b, having a countersunk head is passed through the flat
portion or extension of the tenon and the side.
The junction of the laths to the sides is effected according to my invention as
follows
Instead of making the sides of flat bars, I use either angle irons, or bars of a H, or
a channel, section. At stated intervals along the sides, I punch out slots, d, in the
web of the side lying in the horizontal plane and turned towards the middle of the
bed. These slots are of the same shape as the hooks upon the ends of the laths, D,
which are adapted to engage in thein. Instead of forming a hook upon the end of
the lath, I may form a hole therein, and a second one to correspond, in the web of the
side, and rivet or bolt the two together.
Referring to Figs. 5 and 6, I attach the tenon, B, which is fixed to the pillar in
the manner described above, and by rivetting or other suitable means, a stud, E, of
either a square, triangular, or other suitable shape, and corresponding in point of
thickness with that of the side C, in which latter there is formed, in the proper
position, a hole adapted to receive the stud with a perfect fit. A bolt, b, is used to
fasten the side and tenon together in the same way as described with reference to
Figs. 1 to 4.
As a result of my invention, I obtain a perfect rigidity of connection superior to
that afforded by the dovetail joint, while it is impossible for my improved joint to be
affected by shocks or shaking, or by repeatedly taking the bedstead down and setting
it up again.
It is to be distinctly understood that, although I illustrate and describe two examples
of how this invention can be carried into effect, my invention is not limited thereby ;
but that the details of construction may be varied within the scope of the claims here
following, without departing from the scope of my patent.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In metal bedsteads, fixing a side to a pillar by means of tenon B having formed
on it a recess of a dovetail, square, or other equivalent shape, so as to receive the
end of the side shaped to correspond, they having at the same time a common external
surface.
2. In metal bedsteads, the method of fixing a lath D to its sides C by means of a
simple hook fixed to the end of the lath and adapted to engage in a corresponding
hole formed in the horizontal web of the side, or in substitution of the said hook, by
means of a bolt, or a rivet, or analogous device; substantially as herein before described
with reference to the accompanying drawings.
Dated this 2nd day of January 1890.
