PROVISIONAL SPECIFICATION.
Improvements in Metallic Bedsteads and Cots.
We, STEPHEN WILKES and STEPHEN HENRY WILKES, of the Atlas Bedstead
Company, Bilston, Staffordshire, Metallic Bedstead and Safe Manufacturers, do
hereby declare the nature of this invention to be as follows:—
This invention consists in the herein described improvements in metallic bed-
steads and cots. Heretofore in making children's metallic cots and some kinds of
metallic bedsteads perforated sheet zinc or other sheet metal or alloy is used to
fill the panels or spaces in the sides and ends. This perforated sheet metal or
alloy is not very serviceable as it is often found to break particularly where the
edges are soldered or otherwise fixed to the metallic frames of the sides and ends.
Now according to this invention, instead of employing the said perforated sheet
metal or alloy, we use stout woven wire to fill in the panels or spaces in the tubular
or other metallic frames forming the sides or ends of the metallic bedsteads or cots,
and we bend the edges of the said woven wire around the said tubular or other
metallic frames so as to be firmly secured thereto; or instead of the edges of the
woven wire being beut around the said tubular or other metallic frames they
may be fixed thereto by other means; or the woven wire may be woven on to the
said frames.
The said frames to contain the panels or spaces of woven wire may either be
specially bent and constructed from solid iron or tubes in order that chills may
be cast on to the top of the sides or ends of the cot or bedstead without damage
to the woven wire or the said frames may be made of tubes or rods secured
together by chilled castings in the usual way. Each of the said specially con-
structed frames we prefer to use consists of two upright rods, forming the sides
of the frame, and two cross rods, one forming the top and the other the bottom
of the frame, the ends of the said cross rods being bent outwardly at right
angles parallel with the side rods to which they are welded or otherwise secured.
The upper projecting parts of the frame are then secured to the cross tube or
rod by chills cast thereto. This construction of the frame forms one feature of
this invention.

COMPLETE SPECIFICATION.
Improvements in Metallic Bedsteads and Cots.
We, STEPHEN WILKES and STEPHEN HENRY WILKES, of the Atlas Bedstead
Company, Bilston, Staffordshire, Metallic Bedstead and Safe 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 consists in the herein described improvements in metallic bed-
steads and cots. Heretofore in making children's metallic cots and some kinds of
metallic bedsteads perforated sheet zinc or other sheet metal or alloy is used to fill
the panels or spaces in the sides and ends. This perforated sheet metal or alloy
is not very serviceable as it is often found to break particularly where the edges
are soldered or otherwise fixed to the metallic frames of the sides and ends.

page_text: Now according to this invention instead of employing the said perforated sheet
metal or alloy we use stout woven wire to fill in the panels or spaces in the tubular
or other metallic frames forming the sides or ends of the metallic bedsteads or cots
and we bend the edges of the said woven wire around the said tubular or other
metallic frames so as to be firmly secured thereto; or instead of the edges of the
woven wire being bent around the said tubular or other metallic frames they may
be fixed thereto by other means; or the woven wire may be woven on to the said
frames.
On the accompanying drawing
Fig. 1 represents a cot side filled in with woven wire according to this invention;
Fig. 2 shews a part of the same on an enlarged scale; .
Fig. 3 represents part of another cot side or end illustrating other methods of
constructing the metallic frame and of securing the woven wire fabric thereto;
Fig. 4 also shews a part of a cot side or end in which the tubes or rods of which
the frame is composed are secured together by chilled castings in the usual way;
and
Fig. 5 shews another method of constructing the metallic sides or ends of the
bedstead or cot.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
Referring to the cot side shewn by Figs. 1 and 2 is the woven wire fabric of
the well known kind made of coils of wire intercoiled and filling in the panel or
space in the tubular or other metallic frame formed by the tubes or rods 6' b² c
dd and e. In this example of our invention each edge of the woven wire fabric a
is woven on to the said frame by a coil of wire marked respectively ƒ ƒ ƒ³ f*
engaging with the fabric and coiled round the tubes or rods forming the frame.
The ends of the wires forming the fabric are as shewn in Fig. 2 bent round a stout
wire which is embraced by the coil which secures the fabric to the frame.
A similar stout wire g² is also used to strengthen the fabric as shewn in Fig. 1
where it is cut in a curved form to suit the curved shape of the top of the frame.
When the woven wire used for the panels or spaces is of the kind shewn by
Figure 3 that is made of straight wires the woven wire can be fixed to the frame by
being bent around the rods or tubes of the frame, as shewn at the top and bottom of
the frame in this figure; or the wire fabric can be secured by wire coils as above
described and shewn at the side of the frame in Fig. 3.
Another method which we adopt for securing the wire fabric to the frame is by
using wire rings or hooks which are threaded on to the frame and engage with the
edges of the woven wire fabric.
The said frames to contain the panels or spaces of woven wire may be made
in any well known manner or they may be specially bent and constructed from
solid iron or tubes in order that chills may be cast on to the top of the sides
or ends of the cot or bedstead without interfering with the woven wire. One
of the said specially constructed frames which we may use for the ends of the
bedstead or cot is illustrated by Fig. 3 a part only of the frame being shewn.
This frame consists of two upright rods only one of which (marked ') is shewn
upon the drawing. These rods form the sides of the frame, and there are two
cross rods marked respectively one forming the top and the other the bottom
of the frame the ends of these cross rods being bent outwardly at right
angles parallel with the side rods to which they are welded as shewn in Fig. 3
or otherwise secured as by chills as shewn in Fig. 5. The upper projecting parts
of the frames are then secured to the cross tube or rod e by chills cast thereto.
This construction of the frame forms one feature of this invention. By this
construction of frame or by the ordinary construction shewn by Fig. 2 the corners
of the woven wire fabric are not interfered with as is the case if the rods or
tubes forming the frame are secured together by chills at the corners as shewn
in Fig. 4.
The rods or tubes d' d² (Fig. 1) are strengthened against the pull of the wire

page_text: fabric by the meeting ends of the rods or tubes
being bent up at right angles
and secured to the top cross rail e by the chilled casting j
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. Filling in the panels or spaces of the tubular or other metallic frames forming
the sides or ends of metallic bedsteads and cots with woven wire fabric in the
manner substantially as hereinbefore set forth.
2. A metallic bedstead or cot having the panels or spaces in its side frames or
end frames or in both side frames and end frames filled in with woven wire fabric
substantially as hereinbefore set forth.
3. Making the side frames or end frames of a metallic bedstead or cot in the
manner hereinbefore described and illustrated by Fig. 3 of the accompanying
drawing so as not to interfere with the corners of the woven wire fabric by which
the panels or spaces are filled substantially as herein before set forth.
4. The construction of the top cross bar dd of the cot side or bedstead side
hereinbefore described and shewn by Fig. 1 of the accompanying drawing in which
the meeting ends of the two parts of the top cross bar are bent up at right
angles and secured together and to the cross rail e by a chill for the purpose set
forth.
