I SAMUEL ILSLEY WHITFIELD of Hawkesley Moor Green Lane Moseley in
the County of Worcester Manager do hereby declare the nature of this invention
to be as follows:-
My invention has for its object improvements in metallic bedsteads and
particularly refers to the connecting bar between the dovetail chills of the head
and foot of those bedsteads in which the woven or other mesh forming the bottom
is attached direct or by means of screw bolts to such bars by which I reduce the
liability of their becoming bent buckled or deflected inwards by the strain of
the mesh. By my improvement I obtain the additional strength required in this
direction without any material increase in the weight of metal used and this in a
cheap and simple manner. My invention is applicable to all classes of bedsteads
having a connecting bar between the dovetail chills and to which the mesh is
attached direct.
The aforementioned connecting bar is almost invariably formed of angle iron
and in carrying my invention into effect I truss the said bar on the inside of the
angle iron in the following manner.
provide a tension rod running the full length of the bar and having its ends
fixed by being cast in the dovetail chills at each side of the head or foot as the
case may be the said tension rod being bent out at the centre and a strut inserted
between the tension rod and the vertical flange of the angle iron.
The tension rod is secured to the strut by being flattened and pierced for a stud
piece which is provided on the end of the strut and which enters into the said hole.
By these means the strain from the tightened mesh which has a tendency to
buckle or bend the bar inwards is communicated by the centre strut to the tension
rod by which means the strain is resisted and the bar is kept in a perfectly straight
condition.

I SAMUEL ILSLEY WHITFIELD of Hawkesley Moor Green Lane Moseley
Birmingham in the County of Worcester 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 statement :-

liability of their becoming bent buckled or deflected inwards by the strain of the
mesh. By my improvement I obtain the additional strength required in this
direction without any material increase in the weight of metal used and this in a
cheap and simple manner. My invention is applicable to all classes of bedsteads
having a connecting bar between the dovetail chills and to which the mesh is
attached either direct or by intermediate tightening bolts. The aforementioned
connecting bar is almost invariably formel of angle iron and in carrying my
invention into effect I truss the said bar on the inside of the angle iron in the
following manner.
I provide a tension rod running the full length of the bar and having its ends
fixed by being cast in the dovetail chills at each side of the head and foot as the
case may be, the said tension rod being bent out at the centre and a strut inserted
between the tension rod and the vertical flange of the angle iron.
The tension rod is secured to the strut by being flattened and pierced for a stud
piece which is provided on the end of the strut and which enters into the said
holes. By these means the strain from the tightened mesh which has a tendency
to buckle or bend the bar inwards is communicated by the centre strut to the
tension rod by which means the strain is resisted.
For the better illustration of my invention I have appended a sheet of drawings
which together with the referances thereto more clearly set forth my said
improvements.
Figure 1 is an inverted view of the one end of a bedstead shewing my
strengthening truss attached thereto.
Figure 2 is an enlarged sectional elevation on the line 1-2.
Figure 3 is an elevation of Figure 2.
Figure 4 is a part section through the chills B' shewing the end of the rod A
in elevation.
Figure 5 is a view shewing a modification in the form of bedstead.
By my invention the angle bar B to which the mesh C is attached direct
or by tightening bolts is strengthened and prevented from buckling at the
centre by means of the rod A the ends of which are cast in the chills B at a³ on
each side of the foot and head bars of the bedstead the rod A is bent out from
the vertical flange of the angle bar in the centre and the metal strut E inserted
between the two by which means the strain from the wire mesh which is in the
direction of the arrow W is resisted by the tension of the rod A. The rod A is
flattened out and pierced at a¹ to receive the end e¹ of the strut, the flanges
of the angle iron being also pierced to receive the other end e² of the strut E. The
ends a of the rods are flattened as shewn by Figure 4 before being cast in the
chills for the purpose of preventing them from being drawn from the chill by the
tension of the rod A. In place of the mesh C being attached direct to the angle
iron it may be attached through the medium of a second plate and tightening
bolts and nuts. My invention applies to all classes of bedstead bottoms whether
such bottoms have loose sides between the ends as shewn by Figures 1 or with
the bottoms B in one piece and the ends loose as shewn by Fig. 5.
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
In metallic bedsteads the trussing of the top and bottom angle bars substantially
as and for the purpose herein set forth and shewn upon the accompanying
drawings.
