COMPLETE SPECIFICATION.
Improvements in the Manufacture of Metallic Bedsteads.
I, SAMUEL ILSLEY WHITFIELD of 96, Sampson Road Sparkbrook Birmingham
in the County of Warwick-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:-
Hitherto in the manufacture of metallic bedsteads to which wire mattresses are
attached having wooden or other bars at the head and foot ends of same and which
are tightened up by means of screw bolts passing through the end bars of the
bedstead or through clips or blocks fixed thereon, a difficulty has been experienced
in tightening up the mattress to its full extent, inasmuch as the wooden or other
bars of the mattress which slide upon the side bars or angle irons of the bedstead
are stopped and further tightening prevented by reason of the dovetail castings on
the ends of the side bars which rise at a higher level than the side bars of the bed--
stead thus these dovetail castings or corner blocks form an obstacle to the head and
foot ends of the mattress travelling for when they are screwed up and reach the
junction with the side bars they are stopped from passing further.
I will describe my invention by the aid of the accompanying sheet of drawings.
taken in conjunction with this Specification in which similar letters of reference
relate to similar parts.
Figure 1 illustrates a portion of a side bar or angle iron of a metallic bedstead
connected to the dovetail casting or pillar block.
Figure 2 shews the side bar or angle iron disconnected from the dovetail casting
or pillar block.
Figure 3. is a side view.
My invention relates to a method of construction in order to obviate the difficulty
before referred to and consists in cutting out or raising from the surface of the side
bars or angle irons (A) before casting on the ends or dovetail castings (C) of same
a tongue piece or inclined plane (B) at each end thereof so that when the dovetail
ends (C) are cast on, the tongue piece or inclined plane (B) will form a gradual
slope upwards, from the lower surface of the side bar or angle iron (A) of the
bedstead to the higher surface of the dovetail end or pillar block (C).
The dovetail casting (C) may be sunk or grooved on its upper face to receive
the tongue or inclined plane (B) so that the same may lie flush with the surface of
the casting.
The advantage of this arrangement is that when the end bars of the mattress are
tightened up by means of the screw bolts they readily slide up the tongue piece or
inclined plane (B) on to the upper surface of the dovetail end or pillar block (C)
and the mattress is thus enabled to be tightened up to the full extent of the bedstead
length without any obstacle intervening to prevent its passage.
I wish it to be understood that I do not confine myself to the exact details as
herein specified as I may modify the same to suit various requirements without in
any way departing from the main principle of this my invention.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
The herein described improvements in the manufacture of metallic bedsteads or
any mere equivalents thereof, whereby I form a tongue piece or inclined plane
upon the ends of the side bars or angle irons for the purpose of facilitating the
passage of the wooden or other bars forming the head and foot ends of the mattress

fully set forth.
