Improvements in Bedsteads, Cots, and similar Structures.
I, ADELBERT HENRY GALE, trading as Geo. Gale & Sons, of Upper Dean Street,
in the City of Birmingham, Woven Wire Mattress Manufacturer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to bedsteads, cots, ships berths and such like structures
having woven wire mattresses attached to their tubular frame bars, or other contri-
vances to their component tubular members, and consists in an improved construction
of such tubular frame bars or component parts which allows of the said woven wire
mattresses being attached or slung onto the tubular parts supporting them in a
simple and efficient manner, and so that a neatness and finish to the adjacent parts
is the result. The angles or corner framings are also shaped in a manner to
materially add to the neatness of the structure.
It is usual to attach woven wire mattresses or their like to tubular supports by
means of embracing clips or screw pins or rivets, or by other similar contrivances,
but in no case is a satisfactory neatness and finish of the connection of the parts
obtained.
According to this invention the said tubular members are made of a cross sec-
tional figure somewhat resembling a retort with its stem cut off short near its bulb,
or of a cross sectional figure not a circle but having a three-parts circular formation
and then terminating in a projecting rib, and the said tubes are rolled up from
strips of sheet metal, the longitudinal edges of each being closed upon or over one
another where the rib, as aforesaid, is formed.
This rib, in the case of bedstead side and end hollow frame-bars, is inwardly and
horizontally arranged upon the said bars towards the edges of the meshed bedstead
bottom or mattress, and the crown or top part thereof is shaped in cross section of a
gradual outward curve extending from the top of the said rib to the three-parts
circular part before mentioned.
The formation of the rib upon the hollow or tubular frame bar is for the purpose
of attaching the edge of the mattress to the said rib; vertical holes or piercings
being formed through the said rib with which engage hooks or loop-rings or similar
contrivances upon the mattress edge. By the use of these ribs the edge of the
mattress can be brought close to the side and end frame-bars of a bedstead and
practically flush with the highest point of the said sides and ends, and also the
tubular appearance of the said framings adhered to, which is very important in
bedstead construction.
If the hollow or tubular bars are made from jointless tubing the cross-sectional
shape and the rib, as aforesaid, are rolled or drawn in the tube at the time of its
manufacture. The side and end framings of the bedstead may be chilled-in to
rigid corner blocks or angles, or fitted with dove-tailed connections, but the corner
blocks and adjacent parts fitting into them are cast in conformity with the exterior
shape of the side and end frame-bars, which materially adds to the neatness of the
structure.

page_text: In Fig. 5 is shown a slight modification of the frame bar a³, the ribs a³ being
formed on both sides.
In Fig. 6 the frame bar is made with the one or inner side e open and of a
quadrant or arch-sectioned figure, its bulbous face a² being disposed outwardly, and
its top edge e turned in to constitute the rib for the attachment of the mattress.
Longitudinal ribs e* are formed on the inside of this particular frame bar to give
it strength.
It will be obvious from the Figs. of the drawing that the formation of the
ribs described for the connection of the mattress admits of the latter being brought
close to the frame bars of the bedstead and practically flush with its highest point,
and this without removing the tubular appearance of the said frame bars.
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 attaching woven wire mattresses to bedsteads, the use of a tubular
frame bar having formed upon its top inner side a rib such as a³, which extends its
full length and forms the part to which the mattress is attached, substantially as
described and set forth.
Second. In attaching woven wire mattresses to bedsteads, the use of a tubular
frame bar having upon its top inner side a rib a" and a set back part disposed
underneath the said rib, both of which extend the full length of the frame bar, sub-
stantially as set forth.
Third. The several particular constructions of frame bar and methods of attaching
the mattress edges thereto substantially as described and set forth with reference
to Figs. 2 to 6.
