Wo, STEPHEN WILKES and STEPHEN HENRY WILKES, both of the Atlas Bedstead
Works, Bilston, Staffordshire, Metallic Bedstead Manufacturers, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to an improvement in the construction of the sliding
corner castings of woven wire or spring mattress frames, which castings carry the
end cross piece to which the woven wire or chain top part of the mattress is fixed.
These corner castings are fixed to the ends of the said cross piece, each being partly
formed as a socket to embrace the sides of the frame along which they are moved by
screw bolts to adjust the tension of the wire or chain top part.
In constructing a sliding corner casting according to this invention we cast
in the socket part a strong bar or rib which extends, preferably horizontally, right
across the socket part from one side to the other. This rib has a horizontal screw
threaded hole passing through it in which works the tension screw for moving the
casting to and fro in the side frame to adjust the tension of the woven wire or chain
top. The wooden sides of the mattress frame are slotted for a certain distance from
the end to allow the rib or bar part of the casting to pass through and to move to
and fro along the mattress side. The said bar or rib thus serves the purpose of a nut
for the adjusting screw and considerably strengthens the socket part by being cast
with it and connected to both sides thereof.
Dated this 9th day of August 1887.

page_text: We, STEPHEN WILKES and STEPHEN HENRY WILKES, both of the Atlas Bedstead
Works, Bilston, Staffordshire, Metallic Bedstead 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 has reference to an improvement in the construction of the sliding
corner castings of woven wire or spring mattress frames, which castings carry the
end cross piece to which the woven wire or chain top part of the mattress is fixed.
These corner castings are fixed to the ends of the said cross piece, each being partly
formed as a socket to embrace the sides of the frame along which they are moved
by screw bolts to adjust the tension of the wire or chain top part.
In constructing a sliding corner casting according to this invention we cast in
the socket part a strong bar or rib which extends, preferably horizontally, right across
the socket part from one side to the other. This rib has a horizontal screw threaded
hole passing through it in which works the tension screw for moving the casting to
and fro in the side frame to adjust the tension of the woven wire or chain top. The
wooden sides of the mattress frame are slotted for a certain distance from the end
to allow the rib or bar part of the casting to pass through and to move to and fro
along the mattress side. The said bar or rib thus serves the purpose of a nut for
the adjusting screw and considerably strengthens the socket part by being cast with
it and connected to both sides thereof.
On the accompanying drawing Fig. 1 represents in longitudinal sectional elevation
a sliding corner casting constructed according to this invention for a woven wire or
spring mattress, Fig. 2 is an end elevation and Fig. 3 is a sectional plan of the
same.
The same letters of reference indicate the same parts in all the Figures.
a is the socket part of the casting which slides upon the side of the mattress
frame and c is the upper part which is fixed to the end cross piece d in the usual
manner. is the usual tension screw by which the corner casting is moved along
the mattress side to adjust the tension of the woven wire or chain top and e is the
bar or rib which forms the nut and is tapped for the adjusting screw f to work in and
which according to our invention we cast in the socket part a integral with both
sides thereof so as to connect the two sides together and thus very considerably
strengthening them and preventing their liability to break when the mattress is being
tightened up. The sides b of the mattress frame require to be slotted horizontally

page_text: at g to allow the cross bar or nut e to pass through and move to and fro along the
mattress side.
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:
The improvement in the frames of woven wire or spring mattresses herein before
described and illustrated by the accompanying drawing which consists in casting the
nuts for the tension screws integral with both sides of the sliding corner casting so
as to form a cross strengthening bar connecting the two sides of such casting together,
substantially as set forth.
