An Improvement in Metallic Bedsteads and Cots.
I, WILLIAM FRAZER, of the Firm of Frazer Brothers, of City Works,
Wiggin Street, Birmingham, Warwickshire, Metallic Bedstead Manufacturer, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to he particularly described and ascertained in and by the following
statement:
This invention has reference to those metallic bedsteads and cots in which the
side and end angle irons, or other metal bars or tubes, forming the frame which
supports the bottom of the bedstead or cot, are cast together by corner castings so
as to form the rectangular frame which supports the woven wire or cloth sacking
or other bed bottom.
In a bedstead or cot of this kind the cud angle iron or other metal bars or tubes
to which the woven wire fabric or other flexible bed bottom, or ordinary lath
bottom, is fixed or connected are arranged somewhat above the side angle iron or
other metal bars or tubes, as is well understood, and each of these corner castings
has a projecting tongue or dovetail cast with it to take into a corresponding
dovetailed recess cast in each of the pillar castings. Heretofore the whole weight
of the bedstead bottom or cot bottom and anything resting thereon has been borae
by these dovetailed tongues and dovetails in the corner castings, and it has been
found that the said dovetails are liable to break.
Now according to this invention I so arrange the said corner castings and
dovetailed tongues that the weight of the bedstead bottom and anything supported
thereby is taken off the dovetails and supported directly by the body of the corner
castings and the pillar castings, as I will now fully describe by referring to the
accompanying drawings on which
Fig. 1 is a view looking towards the underside of the foot end of a metallic
bedstead with the corner castings of the angle iron frame made in accordance with
this invention, the angle iron frame and bed bottom being shewn detached from the
bedstead end, and
Fig. 2 shews a portion of one of the corner pillars and one corner of the angle
iron frame with the corner casting thereof in position engaging with the pillar
casting as when the bedstead or cot is fixed up ready for use.
The same letters of reference indicate the same parts in all the figures of the
drawings.
AA are the two side angle irons of the angle iron frame of the bedstead
and A' is one of the end augle irons of the same.
Or instead of angle irons I may
use tubular sides. Two of the corner castings by which the said angle irons are
cast together are shewn and marked B. C is the woven wire or other flexible bed
bottom the ends of which are secured or connected by any convenient means to the
end angle iron A' of the frame and to the other end angle iron not shewn on my
drawing. According to this invention I make each of the corner castings B of the
angle iron or other metal frame rebatted at 6' where the dovetailed tongues are
formed.so that the upper part of each corner casting projects over the dovetailed
tongue thus strengthening the latter and forming a step or shoulder which (as
shewn in Fig. 2) rests upon the pillar casting D when the dovetailed tongues 6* are
inserted in the dovetailed recesses d' and the bedstead is fixed up ready for use.
By the step or shoulder & of each of the corner castings B bearing on the top of
the pillar casting as aforesaid the strain is to a great extent taken off the dovetails
and therefore the same are not so liable to break.

page_text: 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 and cots in which the side and end angle iron or other
metal bars or tubes of the bed bottom or cot bottom are cast together by corner
castings, making the said corner castings rebatted so that the upper part of each
of the corner castings will project above the dovetailed tongues and bear upon the
pillar castings (when the bedstead or cot is fixed up for use) and thus reduce the
strain on the dovetails, substantially as herein before described with reference to
the accompanying drawing.
Dated this 15th day of March 1894.
