Improvements in and relating to Seats and Cushions.
I, MICHEL EDMOND KELLER, of 163 Rue du Faubourg St. Honoré, Paris, in
the Republic of France, Upholsterer, do hereby declare the nature of this invention
to be as follows:→→
.:.
My invention relates to seats and cushions and consists principally in the.mode
of applying thereto a special arrangement of springs.
In my system this special arrangement of the springs ensures the regular and
continuous elasticity of the seat, obviates the accidental. displacement of these
springs, and the inconvenience resulting from the employment of the springs
heretofore used.
In principle my system consists in the mode of assembling a sufficient number of
steel strips or bands forming springs; these strips, or bands are mounted at each of
their extremities upon a rod or bar fixed in the frame of the seat, and their
constant parallelism is maintained by one or more series of two strips or bands
fixed transversely and riveted together at every interval left between two successive
spring strips or bands..
Although my system may be applied to seats of any kind, each different applica-
tion gives rise to accessory modifications, while it remains strictly within the before-
stated, definition,
In order that the new feature of my system may be understood I have
represented it in the Decompanying drawing in its application to a. turuing or
folding seat for theatres..

SVOBODE u Tela, tag Was and us,
I, MICHEL EDMOND KELLER; of 155 Rue du Faubourg St. Honoré, Paris, in
the Republic of France, Upholsterer, do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My invention relates to seats and cushions and consists principally in the mode
of applying thereto a special arrangement of springs.
In my system this special arrangement of the springs ensures the regular and
continuous elasticity of the seat, obviates. the accidental displacement of the said
springs and the inconveniences resulting from the employment of the springs as
heretofore used.
In principle my system consists in the mode of assembling a sufficient number of
steel strips or bands forming springs; these strips or bands are mounted at each
of their extremities upon a rod or bar fixed in the frame of the seat, and their
constant parallelism is maintained by one or more series of-two 'strips or bands
fixed transversely and riveted together at the intervals left between the successive
spring strips or bands.
Although my system may be applied to seats of any kind, each different
application gives rise to accessory modifications, while it remains strictly within
the before-stated definition.
In order that the new feature of my system may be understood I have illustrated
it in the drawing accompanying my Provisional Specification as applied to a
turning or folding seat for theatres.
Figure 1 of the said drawing represents a plan of the seat, showing the arrange-
ment of the springs.
Figure 2 is a transverse vertical section of the same on the line 1-2 of
-Figure' 1.
Figure 3 is a longitudinal vertical section thereof on the line 3-4 of Figure 1.
--Figure 4 shows in detail the assemblage of two longitudinal strips or bands at
one of the points where they are riveted together.
In the drawing a designates the wooden frame of the seat whose exterior form
is immaterial.

A bai 6 fixed on each side and in the interior of the frame serves to hold the
spring strips or bands c in the manner hereinafter set forth:
=
The two bars'b are preferably square, and each extremity of the spring strips or
bands c is attached thereto by a rivet d or by any other means, for example by
giving the extremity of the springs a form similar to that of the bar which carries
them, but so as to leave the bent part e of each strip or band free to give under the
action of the weight:
-C
To ensure regularity in spacing of the spring strips or bands and their return
to the original position when the rest is free I provide at a right angle to the said
strips or bands two other strips or bands ff' which are likewise elastic and placed
one above and the other below the springs c.
11
The two strips or bands ff are connected at each of their extremities, and. by
rivets g in the spaces between each pair of spring strips or bands c so as to form
..

page_text: openings designed for the passage of the said springs c and for keeping them
parallel.
I have shown in the aforesaid drawing of the seat the employment of five spring
strips or bands with a single pair of supporting strips or bands, but I may vary this
number according to the requirements of the various kinds of seats to which my
invention is applied.
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 :-
The arrangement of springs which are specially mounted and cross or traverse-
each other, and their application to seats and cushions of any kind, substantially as.
hereinbefore described with reference to the drawing.
