Improvements in the Manufacture of Upholstery Goods such as
Spring Mattresses and the like.
I, WILHELM KEIL, Upholsterer, residing at Nördlingen, in the Kingdom of
Bavaria, part of the German Empire, 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:-
This invention relates to improvements in the manufacture of upholstery goods
such as spring mattresses and the like and is especially calculated to enable the
ready separation of the upholstering proper from the part to which the springs
are fastened so that both parts may be separately treated and may be cleaned,
aired or repaired whenever desired.
In order that my invention may be carried out by those skilled in the art,
I will proceed to describe the same on hand of the accompanying drawings
which illustrate an embodiment of my invention.
In the drawings:-Fig. 1 is a lateral longitudinal section, Fig. 2 is an end
view of the parts shown in Fig. 1, Fig. 3 is a plan view of the lower portion of
the mattrass to which the springs are attached.
In Fig. 1 of the drawing the two portions of the mattrass are shown with the
upper portion lifted off from the lower portion. The upholstering is contained
in the wooden frame of the upper portion to the longer sides of which pivots c¹
are attached by suitable bearings c.
In the position shown in the drawing and in which the two portions of the
mattrass are separated from each other, they can be easily aired, repaired and
cleaned since the bottom side of the upholstery and the top of the springs are
perfectly exposed. If it is desired to re-unite both parts with each other, it
is only necessary to place the upper upon the lower portion whereupon the bent
lever which turns upon its pivot c fastened to the bearing c³, is reversed so
that its bent portion engages the stud c¹ thus securely fastening both parts
to each other. In order to guide the movement of the lever and in order to
prevent its being thrown forward too far, the iron strap is provided. The
union of both portions of the mattrass is shown in Fig. 2.
The frame a of the lower portion of the mattrass is cut off at the top so as to
be of somewhat smaller diameter at the top than at the bottom thereof as is
clearly shown in Fig. 3 of the drawing. The said cut out portion at the top
serving for the fixing of the cords or straps by which the springs are united at
the top. If these cords or straps were attached upon the high edge of frame a,
they would get between the edges of the two portions of the mattrass upon the
same being assembled together and would not only prevent them to register
exactly with each other, but would also present the inconvenience of easily
becoming worn by pressure and friction. By arranging the cords or straps upon
the surface of the tapered off portion a¹ however they are not only prevented
from being injuriously acted upon by the edges of the frame, but an always
exact adjustment is also secured.

page_text: It is obvious that in place of the connecting parts c¹ to e, any other device
serving the same purpose, especially those whose action is automatical, may be
used without departing from the spirit of my invention, thus also the shape of
the cut out portion a¹ may be varied lateral displacement may be prevented by
the arrangement of studs "d.
Having now 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. Improvement in upholstery goods, mattrasses and the like, in which the
upholstery proper is contained in the upper portion and the lower portion of
the horizontally divided frame is to contain the springs which said two parts
may be connected and disconnected at will by any suitable means, the lower
portion being recessed or tapered off at the top for the reception of the cords
or straps used for fixing the springs to the top of the lower portion, substan-
tially as and for the purpose set forth.
2. In a horizontally divided piece of upholstery, mattrass and the like the
lower portion of which serves for the reception of the springs while the uphol-
stery proper is contained in the upper portion, a bent lever pivotically attached
to the lower portion and made to engage with a stud attached to the upper
portion for effecting the union of both parts substantially as and for the purpose
set forth.
3. In a horizontally divided piece of upholstery, mattrass and the like studs ()
which prevent the lateral displacement of the parts substantially as and for
the purpose set forth.
