I, HERBERT JOHN ALLISON, of the firm of Allison Brothers, of 52 Chancery
Lane, London, in the County of Middlesex, Patent Agents, do hereby declare the
nature of said invention for "IMPROVEMENTS IN FOLDING WIRE MATTRESSES"
and in what manner the same 18 to be performed, to be particularly described
and ascertained in and by the following statement, reference being had to the
accompanying drawings and to the letters of reference marked thereon
-
The invention relates to bed bottoms made of woven wire, and its object is to
construct such a bottom of narrow parallel strips that can be readily detached for
transportation, and which may be united by detachable wires along their edges in
such manner that each strip may be given a different degree of tension and that all
the strips will swing together laterally in the same manner as in bed bottoms made
in one piece
The invention consists in the construction and novel arrangement of parts
hereinafter described and pointed out in the appended claims
In the drawings
-
Figure 1 represents a plan view of a bed bottom complete
Figure 2, is a plan view of the same in the act of being set up
Figure 3, is a view showing the construction and arrangement of the side beams
of the frame, and
Figure 4, is a detail view of the end plates on the strips of fabric that compose
the bed bottom
"
A' represents the frame of the bed bottom, composed of the longitudinal side
bars A and the end bars A' The end and side bars are secured together at the
corners of the frame by the bolts c which pass through the vertical blocks b,
preferably made cylindrical
Bare truss or strengthening strips overlying the side bars A
Each strip B
has its centre secured to the centre of a bar A by the bolt a, and a nut thereon.
The strips B are sprung with their convexity downward and the ends rest
upon the blocks b, which are properly beveled to allow the ends to lie on their
whole surface

page_text: The bolts c pass through the bars A, blocks b and the ends of the strips B, and
also through transverse bars C upon which their heads lie, the nuts that secure
them being below the bars A, as shown
D are the narrow longitudinal strips of which the bed bottom is composed The
said strips have properly secured to their ends the plates D¹, D', which underlie
the strips and are bolted through the same to similar plates d which overlie the
strip The plates D¹, d, have corresponding holes through them by means of
which and proper pins or screws d³ they may be attached further in or out on the
end rails A
The strips D have additional wires worked into their edges at a³, so as to :
reinforce the same and enable them to bear the strain of the detachable wires a³
which connect the strips and cause them all to swing laterally together
The wies a, hook at their ends, preferably, into the reinforced edges of the
strips D but may be attached in any other suitable manner
It is evident from the foregoing description that the frame A may be readily
knocked down, the strips D detached from the end rails and the whole packed for
transportation
The fact of the strips D being narrow allows them to receive greater tension
during attachment to the end rails, with the exercise of less force than if they were
wide, and therefore the bed bottom may be more readily set up
The narrow strips also permit different degrees of longitudinal tension to be
given to different parts of the bed bottom considered as a whole, so that either the
side strips D may be made more tense than those in the middle or any strip when
stretched by use may easily have its former tension restored
The strips are easily attached further in or out on the end rails A¹ by means of
the pins d and holes & of the plates D¹ and d.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1 The combination in a bed bottom frame or woven wire mattress fiame, of
the longitudinal straight side bars, the continuous bowed bars secured on top of the
Bide bars at the middle of their length, the end blocks b between the ends of
straight side bars and the bowed bars, the transverse bars C and bolts c securing
the parts of the corners of the frame together, all constructed and arranged sub-
stantially as and for the purpose specified
2 A bed bottom composed of a number of narrow parallel strips of woven wire
or other suitable fabric detachably secured within the bed frame and reinforced
along their edges by additional wires to strengthen or stiffen said edges, and the
stiff detachable wires a², connecting the adjacent edges of the strips so that the
latter will all move together laterally in the same manner as a bed bottom made in
one piece substantially as specified
3 The combination with the end rails of a bed frame A¹, of the narrow strips D
of woven wire, reinforced along their side edges by additional wires and provided
with end plates D¹ and d, adapted to be connected further in or out on the upper
surface of the end rails, according to the amount of tension required, and the stiff
detachable wires a³, connecting at intervals, the adjacent edges of the strips D, sub-|
stantially as described
