SAMUEL WILSON of the Firm of Wilson Bros. & Co. Ledsam Street Birmingham
Bedstead Manufacturer do hereby declare the nature of this invention to be as
follows:-
==
The object of this invention is to so construct a metallic bedstead that a woven
wire or other description of spring mattress may be readily and more economically
attached thereto than hitherto. In working out my invention I continue or carry
down the upright or sheet iron or other panels at the head and foot parts of the
bedstead to a suitable height above the socket corners of the pillars of the bedstead
in which position I chill or cast on the bottom cross bar of the said uprights or
panels to the pillars of the said head & foot parts. I then pass the tightening or
adjusting bolts directly through the said bottom bar which is made of sufficient
diameter and strength to allow for the thoroughfare holes which are formed in the
said bottom bar which in these particular parts I may strengthen by chilling on a
band of iron. I thus dispense with the end angle or tube bar to which it has been
usual to attach the mattress to and so manufacture the bedstead in a more
economical and equally efficient manner.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Metallic Bedsteads, whereby
the Attachment of Spring Mattresses thereto is Facilitated.
I, SAMUEL WILSON, of the Firm of Wilson Brothers and Company, of Ledsam
Street, in the City of Birmingham, Bedstead Manufacturer, 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, or in the manufacture or construction
of bedsteads, or detail parts of them, viz., those parts to which the ends of a woven
wire or other distensible sacking or mesh are connected.
Heretofore the distensible sacking or woven wire meshed bottoms have been
directly attached or suspended to the bedstead bottom or framing through or by
brackets, either loose, or attached to the end angles, or directly through holes in
the end angles or rails or bars which rails have sometimes been elevated, above the
plane of the sides by chilling the said end angles or bars out of the centre of the
dovetail corner castings, so as to give the required height above the plane of
the side angles.
By my invention, the said brackets and the said end angles, rails or bars are
entirely dispensed with, and in lieu thereof, 1 employ the bottom or cross bars,
(which form the boundary of the filling-in panels or step rods of the head and
foot rails of the bedstead and to which the said step rods are chilled, but at a lower
depth than and conveniently nearer to the dovetail corner castings than usual), of
the head and foot rails as the means to attach or connect the said distensible
sacking to the bedstead. These bottom bars, I make of a larger diameter than
usual and having suitable all-through holes formed in them. I chill the said
bottom bars to the panel or upright step rods of the rails, and at the same time
horizontally from pillar to pillar or outside tube to outside tube by a chill separate
and distinct from the dovetail corners.

page_text: Instead of drilling the connecting or tension screw holes through the said bottom
bars I sometimes prefer to form the said holes in the following manner :-
I make the said bottom bars in three parts which are joined together and the
holes made in suitable positions by chilling junctions of iron round the said divided
bottom bars in mounds having suitable taper laid-in drifts which are removable
after casting thereby forming the holes for the said screws.
At the same time, these junction chills or castings greatly increase the strength
and rigidity of the bars as well as forming the extended bearings for the bolts or
tightening up screws.
The forming of these holes and the junction chills of the said bottom bars to the
outside framing of the bedstead are subsequent to the casting on of the dovetail
corner sockets.
Figure 1 of the accompanying drawing represents a bedstead fitted and provided
with improvements made according to my invention.
Figure 2 represents a transverse section of the same through the dotted lines A. B,
Figure 1, showing how the uprights of the end framings are united to the sacking-
bottom suspension bars through chilled junctions.
Figure 3 represents a section upon the dotted lines CD Figure 2 of the head
end of the bedstead.
a is the head end and 6 is the foot end of the bedstead, each consisting essentially
of tubular border or boundary edgings or frames c, with the upper parts c³, of them
provided with inwardly presented open joints c¹, wherein sheet metal panellings d
are fitted, (or the filling in may be bars of metal or tubes).
e are tubular sides, secured to the pillars or uprights c³, of the tubular framing c,
by junction chills f.
The bottom cross bars of the head and foot rails are united to the uprights of
the framing c, by junction or band chills h, and which said hollow or other bars g,
are each made preferably in three parts as before described and united by the
junction or strengthening chills j, and through holes i in which, tensioning, affixing
or tightening screw pins k, pass.
The shank ends k², of both the drawing-up and affixing pins at the respective
ends of the bedstead, take through plain holes m³, of the mesh end bars m, of the
meshes or distensible sackings m', and take through non-rotating screw nuts or
screw boxes n.
The lower parts of the uprights of the end frames are tied together by a supple-
mentary under bar o, chilled together by chills o².
Instead of supporting & stretching the distensible sackings from bottom bars,
they may be supported from brackets carried by the bottom bars, or they may be
distended and supported from the upper parts of the end framings.
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 :-
First. In metallic bedsteads, mounting or supporting and stretching distensible
or other like sackings from the bottom bars, or from brackets carried by the
bottom bars, of the head and foot rails of metallic bedsteads, substantially as
described, and set forth.
Secondly. In metallic bedsteads, mounting or supporting and stretching disten-
sible and other sackings from the bottom rods of the end rails or the upper parts
of the end framings, and with the said brought down rails united to the uprights
by independent chill junctions, and not being part of the general corner castings,
substantially as described and set forth.
Thirdly. In metallic bedsteads, supporting the distensible or other sackings or
bed bottoms from bottom rods (of the head and foot rails) each made up of three
sectional parts, and united together by cast junction bosses or chills, wherethrough
holes for the tensioning screws of the sackings directly pass, substantially as
described and set forth.

page_text: Fourthly. In metallic bedsteads, the general construction, arrangement and
combination of the parts substantially as described and set forth.
Dated this 12th day of July 1893.
