FREDERICK NORTH 147 Goldsmiths Row South Hackney Engineer WILLIAM
GLENNY. 147 Goldsmiths Row South Hackney Engine Fitter do hereby declare the
nature of this invention to be as follows:-
Our invention consists firstly of a novel construction of spring mattress which
shall present the advantages of great elasticity lightness, simplicity of construction and
cheapness of production.
The invention consists secondly of a construction of spring mattress which in
addition to the above advantages will be capable of being increased or reduced in
width, thus one mattress may be readily expanded or contracted to suit any
Beadstead.
In constructing a mattress according to this invention we make use of coiled
springs of novel form. The coil at one end of the spring is of large diameter, the
coils gradually decreasing in diameter as they approach the other end where the
spring terminates in a central pin by which it is rivetted to its support.
DESCRIPTION OF INVENTION.
The support of the springs will consent of parallel bars of steel placed longways of
the mattress at suitable distance apart and connect togeather by transverse bars at
each end of mattress and to which the ends of the longitudnel bars are secured, each
of these longitudnel bars serve to support a row of coiled springs the smaller end of
each spring being rivetted to it underlying Bar, the other row of springs on each
side of mattress are connected by longitudnal Bars top & bottom and also by sliding
springs and stays the upper side of the coiled springs are connected togeather by short
lengths of chains & persent a surface suffecently even and continous to afford an
effectual and elastic support to an ordinary Feather bed or Wool mattress placed
thereon.

page_text: In construction a mattress capable of being altered in width to suit any Bedstead
we use the longitudnal Bars as before described to support the springs, but they are
connected by short bars rivetted togeather in such a manner as to form Toggle joints
between the longitudnel Bars, the arrangements permit longitudnel Bars with three
row of springs being moved towards and from each other thus increasing or
deminishing the width of the mattress.
Improvements in Spring Mattresses.
We FREDERICK NORTH 147 Goldsmiths Row Hackney Road E. and WILLIAM
GLENNY 36 Southwold Road Upper Clapton London E. 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:-
Our Invention consists firstly in a novel construction of spring mattrass which
shall present the advantages of great elasticity lightness simplicity cheapness, and
durability.
The Invention consists secondly in a construction of spring mattress which in
addition to the above advantages will be capable of being reduced or increased in
width so that the same mattrass may be readily expanded or contracted to suit any
Bedstead from a width of 2 feet 6 ins. to 5 feet 6 ins. or other dimensions.
In constructing this mattress according to this Invention we make use of coiled
springs of novel form, the coil at one end of the spring is of large diameter the
other coils gradually decreasing in diameter as they approach the other end which
may be secured to its support by Rivet, screw or Bolt & nut.
This spring is not only available for use in spring mattresses but is also the best
that can be used for all and every description of Upolstery work owing to its lightness
compactness and cheapness.
The supports of these springs in the mattress will consist of parallel bars A of Iron
or steel placed lengthwise of the mattress at suitable distances apart to which said
bars the small end of the springs is secured by Rivet, screw, or Bolt and nut.
The outer rows of springs on each side of the mattress are connected by longitudinal
bars on the top as well as the bottom of the mattress and additionally supported by
short bent springs D resting on the bars G.

page_text: The upper or larger side of the coiled springs are connected together by short
lengths of chain E and present a surface sufficiently even and continuous to afford an
efficient and elastic support to an ordinary Feather Bed or other Mattress placed
thereon.
In constructing a Mattress capable of being altered in width to suit any Bedstead
the longitudinal bars already described are connected by short bars F pivoted together
in such a manner as to form Toggle joints between the longitudinal bars this arrange-
ment permits the longitudinal bars with their rows of springs being moved towards or
from each other thus increasing or diminishing the width of the Mattress.
The transverse bars G are the slides which open to adjust the Mattress to any
sized Bedstead, or to close the Mattress for economy of space or for transit, and
are kept in position by the Clips H which are riveted on to the longitudinal
bars.
The bent springs D are riveted on the longitudinal bars and also to the back
part of the outside coil spring C which abut on the ends of the Mattress to
prevent the same from canting inwards and to give greater rigidity where most
required.
Being constructed of metal only this Mattress will possess great durability and from
a sanitary point of view for the same reason it will be almost impossible to transmit
any contagious disease.

Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1st. A novel construction of Spring Mattrass which shall present the advantage of
great elasticity, cheapness and durability.
2nd. That the said mattrass shall be so constructed as to be easily expanded or
contracted in width so that the same mattrass could be used on Bedsteads of various
widths.
3rd. That the spring C used in the construction of these mattrasses is of novel form
being of large diameter at one end the other coils gradually decreasing in diameter as
they approach the other end, presenting when compressed almost a flat surface each
coil lying within the one next larger to it.
4th. Which Spring we claim to be used in Spring Mattrasses and Upholestery
Work.
