Improvements in Spring Bottoms or Mattresses for Beds and other
Furniture.
I, FRANZ KRIEG, of 7, Alte Leipzigerstrasse, Berlin, in the Empire of
Germany, Gentleman, 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 bottoms or mattresses for
beds and other furniture, in which a strap and springs are arranged in such a
manner that the pressure exerted at any point upon such bottom or mattress
may be evenly distributed over all parts and that undue pressure on any one
part of it may be obviated.
In the accompanying drawings, a specimen of such spring bottom or mattress is
represented.
Figure 1, is a plan view.
Figure 2, a section along line X-x of Figure 1, and Figures 3, 4 and 5 are
details of the method of fastening the springs to the bottom-frame.
The bottom frame a, though having a rectangular form in the drawing, may be
of any size or shape according to requirement-and may be constructed of any
suitable material. To the frame a, spiral springs b, each made of one and the same
piece of metal, are fastened in the manner shewn in Figures, 3 to 5. The ends of
each spring b, are bent down and held together by a common throat band or
hoop c, and thus attached to the frame a. By this arrangement the spring b, is
prevented from being lifted. In order to prevent the spring b, from being bent
inward connecting wire d is provided, one end of which is attached to the
frame a, by an eyed piece e, and the other fixed to the spring at the point where
its two spirals part each other. Endless straps g, are passed through the loops of
the springs b, and interlaced, as shown in Fig. 1, wherein the straps made use of
are marked g, to g¹.
The number of straps, g, g', etc., made use of is considerably reduced in
comparison to the number of straps employed with the interlacing method at
present in use, this being due to the peculiar method of interlacing of the straps
(Fig. 1). Any one or other of the straps g, is held by being passed through the
middle parts of the spring b (Fig. 4) round which it is simply lapped or turned
(Fig. 3) and then carried in an oblique direction and finally the ends are joined.
As the straps 9, 9, 99, 9 may be made of one and the same piece the
disadvantageous multiciplicity of joints is dispensed with.
A wire connecting the whole of the springs b by some suitable binding device,
as well as the peculiar method of interlacing the straps g, cause the pressure upon
the latter to be distributed over all the springs 6 and the whole texture of the
interlaced straps, the superficial point upon which the pressure is exerted being
thus of no consequence. It is one and the same if the pressure be brought to bear
upon the middle of the bottom or mattress, on one side, or upon a corner part
of it.
Having thus 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:
"
A spring bottom or mattress for beds and other furniture. composed of a

page_text: frame a provided with 'supporting springs b. b. b. round the middle parts of which
the straps such as g, are free to move, and are loosely wound, said straps being
then interlaced in such manner that the parts thereof cross themselves and run in
an oblique direction, for the purpose of distributing the pressure upon said bottom
or mattress over all the springs and 'the whole texture of the straps substantially
as shewn and described....
