EMILL HOCK, ALBERT HOCK, and ALEXIS FERDINAND PARMENTIER, all of Paris,
in the Republic of France, but temporarily of 4, South Street, Finsbury, in the
"IMPROVEMENTS IN SPRING MATTRESSES AND
County of Middlesex, Manufacturcis
SEATING 1 OR SOFAS, CHAIRS, AND OTHER SIMILAR ARTICLES OF FURMIURE, PART
OF SUCH IMPROVEMENTS BEING APPLICABLE TO OTHER PURPOSES"
This Invention consists mainly in the construction of improved springs for
matti esses, sofas, chaus, and other similar articles of furniture
The improved spring, from its shape, nature, its application to inatti esses, beds,
and the seats of benches, chans, sofas, and other articles of furniture, by the method
of covering, fixing, and mounting it, and its special employment for various purposes
gives it great advantages over the spings hitherto employed for similai pui poses
To make our Invention better understood we will proceed to describe the same
by reference to the accompanying Diawing
The improved spring is constructed of one or several cast and tempered stecl
blades, the numbei and dimensions of which vary according to the strength and
elasticity required Figures 1, 2, 3, and 4 of the Diawing shew one, two, three,
and four bladed springs respectively
The blade or blades can be arranged in several ways, although we prefer to give
them an elongated oval form and to bend them at each extremity into a cuive, as
shewn at Figures 1, 2, 3, and 4 of the Diawing
The spings are fixed by then bottom parts to the article of furniture (of iron) by

page_text: means of livets or screws and nuts adapted to the cross bars, or by other suitable
means (the plate a, Figure 5, is for fixing the springs to woodwork) The upper
parts are also similaily fixed if the usual bands or laths of hoop non are employed,
but we preferably employ for the covering, metallic straps or webbing made of
copper and non wie woven together, as shewn in Figure 6, the copper wies being
placed at right angles to the non wires In this caso the spring is provided at top
with a kind of ring b, as shewn at Figure 5, by which means it is attached to tho
heiein-before described metallic webbing. Any other suitable metal we may be
employed for the webbing
This improved metallic webbing, which we can make of various widths and
strength according to the use for which it is required, can be advantageously
employed, in place of the usual hempen webbing, for the bottoms of sofas, chans,
seats, and other similar articles of fuiniture
The unproved metallic webbing does not stretch, allows of examining the interio1
of the article of furniture without taking it to pieces, and by its open construction
prevents accumulation of dust and insects, and consequently the damage caused
thereby
The improved webbing may also be employed for the driving bands of machinery.
Mattresses furnished with our improved springs may be either separate from or
fixed to the bedstead In-either case they are both much stronger and lighter than
those hitherto in use The putting together and taking to pieces of the mattress is
also more easily offected, and what is of great importance the cost is greatly
reduced
An iron bedstead with a fixed mattress may by our improvements be folding or
otherwise, and as such it will weigh less than an ordinary mattress alone, and it
can be transported and set up more easily than any bedstead with an ordinary
mattress
The disadvantages of spiral spings are that they twist and get displaced by
bending and cause disagreeable noises Our improved springs do not get out of
place and cause no noise whatever be the weight or size of the person resting
on them
And further, from their well compensated clasticity they maintain
then equilibrium in all positions, that is to say, equally in the middle and at the
sides of the mattress
These advantages are of great importance to invalids, and as both the separate
and fixed mattresses are quite open they are specially suitable for hospitals, piisons,
banacks, colleges, and in all places where, from a laige number of persons sleeping
under one roof, hygienic and sanitary precautions are rendered necessary
It will be understood that our improved mattresses can be cleansed and made
wholesome by washing or otherwise, the matti esses not being covered or furnished
with fabric, although of course they can if requned be covered with suitable
material It will also be understood that our improved springs can be adapted to
mattresses with wooden frameworks, similarly as the ordinary spiral springs
To give greate softness to the clastic movement of a number of spings we
mount the covering of the mattress, whether detached or fixed, on four small bars
forming a fiame c, Figure 7, which fiame rests at its four coiners on 1ods & moveable
in tubes e, for the better class of furniture, but for the common class of furniture
we employ S shaped hooks f, Figure 8
Figure 9 shews a perspective view of a complete mattress constructed according
to our unprovements, and Figure 10 shews a similai mattress fixed to a bedstead
and forming part of it
The method of applying our improvements to the seating of sofas, chairs, and
other similar articles of furniture, will not need explanation, as it will be easily
understood from the foregoing description.
Having thus described our Invention and the best means with which we are
acquainted for carrying the same into effect, what we claim is,—
The improvements in sping mattresses and seating for sofas, chairs, and other
similar articles of furniture, part of such improvements being applicable to other

page_text: purposes, substantially as herein-before described and represented in the accom-
panying Diawing
In witness whereof, we, the said Emile Hock, Albert Hock, and Alexis
Ferdinand Pai mention, have hereunto set out hands and seals, this Tenth
day of February, in the year of our Lord One thousand eight hundred and
seventy-seven
