AN IMPROVEMENT IN MATTRESSES
Year: 1880

at the Office of the Commissioners of Patents on the 26th November 1880.
WILLIAM EDWARD BROWN, of Camden Town, in the County of Middlesex.
"AN IMPROVEMENT IN MATTRESSES."
My Invention has for its object to enable a wool, hair, or other similar mattress
to be constantly shifted in position on the bedstead, so as to prevent the mattress
becoming hollow and consolidated in places from the weight of the body resting
always on the same part of the mattress, as is usually the case. And my Invention
consists in an endless inattress, that is to say, a mattress of double the usual length,
folded or doubled upon itself, with the ends of the tick or case united. Or it may
be of the usual length and double the usual width, and made into endless form and
folded on itself as before, the folds being in this case at the two sides of the
mattress.
In either case the covering of the mattress has the ends or sides that are to be
united open, so that the union is made by a seam in the covering made without
any solution of continuity in the wool or other stuffing.
By slightly altering the position of the folds of the mattress every time the bed
is made, a fresh part of the mattress is brought into use.

"AN IMPROVEMENT IN MATTRESSES."
My Invention has for its object to enable a wool, hair, or other similar mattress
to be constantly shifted in position on the bedstead, so as to prevent the mattress
becoming hollow and consolidated in places from the weight of the body resting
always on the same part of the mattress, as is usually the case with ordinary
mattresses..
And my Invention consists in an endless mattress, that is to say, a mattress of
double the usual length, folded or doubled upon itself, with the ends of the tick
or case united. Or it may be of the usual length and double the usual width, and
made into endless form and folded on itself as before, the folds being in this case
at the two sides of the mattress. By sliding the upper upon the lower part of the
mattress, so as to fold or double the mattress in different places every time the bed
is made; another part of the mattress is brought into use.
DESCRIPTION OF DRAWINGS.
Figure 1 is a perspective view of an endless mattress constructed according to
my Invention; Figure 2 is a longitudinal section; and Figure 3, a cross section
of the same, these two latter Figures being drawn to a smaller scale.
The endless mattress A, A, is made in the flat in the usual way of making
mattresses, except that the tick or covering is left open at the ends to be united,
as hereafter described. In the flat the mattress is of less (say half) the usual
thickness and twice the usual length, or twice the usual width (according as it is
desired to have, the folds a at the ends or the sides of the bed), so that when
doubled or folded on itself as shown, it will make a mattress of the usual size and
thickness.
The mattress having been made and stuffed in the flat, the open ends of the tick
or covering are brought together end to end and united by sewing, forming the
⚫ seam shown at b, there being however no break or interruption at this seam in
the stuffing which is perfectly continuous.
I do not limit myself to any particular way of making the tick or covering. In
the example shown the outer surfaces a', a², of the mattress which are exposed to
wear, are formed of strong tick or other fabric usually employed; the inner
surfaces a³, which lie on one another and are not exposed to wear, may be of lighter
material united to the outer tick by seams at c.
Having described the nature of my Invention, and the manner of performing
the same,
I declare that what I claim as my Invention to be protected by the
herein before in part recited Letters Patent is,-
itself
An endless or continuous mattress formed by doubling the mattress upon
and uniting the ends or sides, substantially as and for the purpose specified.
In witness whereof, I, the said William Edward Brown, have hereunto set my
