Improvements in Mattresses.
I, CHARLES JUNGE, of Lincoln Chambers, 75, Chancery Lane, London, W.C.,
Consulting Engineer, 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 relates to adjustable mattresses and will hereinafter be set forth
with reference to the accompanying drawing, in which
Figures 1 and 2 show plans of two forms of mattresses;
Figure 3 is a section showing one end of a mattress frame provided with a fasten-
ing device consisting of a hook shaped plate and a hook.
Figure 4 is a longitudinal section of an improved mattress.
Figure 5 is a perspective view illustrating a mode of supporting and adjusting
the head rest.
As will be seen in Figure 4, the springs e are arranged between a series of wire
ropes 1 in such a manner that one of these wire ropes will be above and the other
below said spiral springs. These wire ropes 1 pass round rollers 2 fitted to turn about
pivots 3. The more the wire ropes are caused to approach each other by the weight
of the person lying on the bed the stronger will be the pressure by which the
spiral springs e are compressed, and the less elastic they will be. In this arrange-
ment the two rollers 2 are supposed to be fixed, that is to say immovable relatively
to the mattress frame 4.
I may also fix a head rest 7 by means of racks 11 and 12 as shown in Figure 5
the racks 11, which are furnished with teeth pointing upwards and turned towards
the foot of the frame, being secured to the mattress frame 4, whereas the rack 12
has its teeth turned downwards and towards the head of the frame and is pivoted
to such head. On the rack 12 being turned upwards the horizontal transverse
piece 51 of the stay 5 may be moved from one of the series of notches or recesses
in the rack 11 to the other, thereby changing the tension of the wire ropes 1 the
lower ends of said ropes being fastened to the head of the mattress frame 4, and
passing around the roller 2 at the foot of the frame 4, returns above and is fixed
to the transverse piece 5¹, said head rest being covered with woven wire fabric or
other suitable material.
The tension of the wire ropes 13 may also be produced independently of the
position of the head rest by forming the said ropes with double ends and bringing
such ends together by passing a slide 14 over them as shown by dotted lines in
Figures 1 and 2. The arrangement of the wire ropes 13 may be such that they
will either be between the spiral springs e or that they will cross each other at the
centre of said spiral springs.
In the constructional form shown in Figure 1 there are slides 14' which pass
over the wire ropes themselves, whilst hooks 142, through which the wire ropes
pass, engage with a hook shaped plate 15 of the mattress frame 4, as indicated in
Figure 2

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:
First. An adjustable mattress wherein the ropes 1 are connected with the trans-
verse piece 51 of the head rest 7, the latter being held in position by racks 11 and 12,
substantially as set forth.
Second. An adjustable mattress wherein the tension of the wire ropes 13 acting
upon the spiral springs e from below and above, or from below, Figures 1 and 2,
is produced by slides 14 adapted to move upon two wire rope ends forming a wedge
together, substantially as set forth.
