Improvements in Spring Mattresses.
I, MAX SILVERMAN of 6, Fashion Street, Spitalfields, London, E. Grocer 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 Improvements in Spring Mattresses and has for object so
to construct and arrange the same that they shall be capable of expansion and
construction in their width, thus adapting them for use upon different sized bed-
steads, and again when in their contracted position rendering them readily portable
and convenient and compact for storage, such as when not required for use or when
being transported or conveyed from one place to another.
And in order that this my invention may be readily understood I will describe
same with reference to the accompanying drawings in which similar letters of
reference indicate like parts in each of the figures.
Fig. 1. is an isometrical view of a spring mattress constructed in accordance with
this invention and shewn as expanded to its full width.
Fig. 2. is a similar view shewing the mattress contracted so as to be adapted for
a bedstead of a smaller size and Fig. 3. shews the same folded into its smallest
compass to allow of easy portability and compactness for storage.
In these two latter views the springs e however are not shewn as not being
necessary for the purpose of illustrating the invention.
Now in accordance with this invention and to attain the objects aforesaid I
connect the upper longitudinal bars to each other at their ends by means of jointed
transverse bars or plates, and I have similar jointed transverse bars or plates con-
necting the ends of the lower longitudinal bars. The upper and lower sets of
longitudinal bars are then connected together also by means of jointed bars or
plates all as will be seen on reference to the drawings aforesaid in which a a a are
the upper longitudinal bars and bb bb their transverse connecting plates or bars.
These latter are jointed centrally between the longitudinal bars a as at c and their
ends are pivotally connected to the said longitudinal bars as at d. eeee are
springs interposed between the upper and lower longitudinal bars. fff are the
lower longitudinal bars and 9 g 9 g their transverse connecting bars or plates
jointed at hand pivotted at i to the bars f.
At the ends of the two sets of longitudinal bars I have, connecting the upper
set to the lower, the folding plates or bars k. These bars or plates k I pivot at
to the centre bar of the upper set of longitudinals and at m I pivot them to the
outer bars of the lower set, or vice versa. I also joint said bars or plates & centrally
as at n.
It will at once be seen that the mattress constructed as above described may
readily be extended to its full width as shewn in Fig. 1. or where it is desired to
be used upon a bedstead of a smaller width it may be contracted as shewn in
Fig. 2. so as to be adapted to such smaller bedstead, whilst, when it is not required
for use it may be still further contracted and be folded into its smallest compass as
shewn in Fig. 3. and thus be rendered very convenient for carrying or packing, all
as aforesaid.
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
1 T
combination of nonta froming m

described and shewn in the accompanying drawings.
2. In spring mattresses the transverse folding bars or plates bg connecting the
longitudinal bars af for the purpose of permitting the mattress to be expanded or
contracted in its width at will, substantially as hereinbefore described and shewn.
In spring mattresses the combination with the longitudinal bars af and transverse
folding bars bg of the folding arms or plates k connecting the upper and lower
sets of longitudinal bars together at their ends substantially as shewn and
described.
