Year: 1861

page_text: LETTERS PATENT to Edward Peyton, of Birmingham, in the County of
Warwick, Manufacturer, and William Fothergill Batho, of the same
Place, Manager, for the Invention of "IMPROVEMENTS IN LATHS FOR
SUPPORTING BEDDING AND CUSHIONS IN BEDSTEADS, COUCHES, SOFAS, AND
SEATS."
Sealed the 16th May 1862, and dated the 22nd November 1861.
PROVISIONAL SPÉCIFICATION left by the said Edward Peyton and Wil-
liam Fothergill Batho at the Office of the Commissioners of Patents,
with their Petition, on the 22nd November 1861.
We, EDWARD PEYTON, of Birmingham, in the County of Warwick, Manu!
facturer, and WILLIAM FOTHERGILL BATHO, of the same Place, Manager, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN LATES
FOR SUPPORTING BEDDING AND CUSHIONS IN BEDSTEADS, COUCHES, SOFAS, AND SEATS,
to be as follows:-.
Our Invention consists in constructing elliptical laths, each separate lath
being composed of two strips of metal united or brought together at their two
ends,, and bowed towards the centre, then between the two strips we fix hoops
of steel, volute or other metal spring or springs to constitute spring laths for
cunporting bodding cushions and seats.

Patent, bearing date the Twenty-second day of November in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her. heirs and successors, give and grant unto
us, the said Edward Peyton and William Fothergill Batho, Her special
licence that we, the said Edward Peyton and William Fothergill Batho, our
executors, administrators, and assigns, or such others as we, the said Edward
Peyton and William Fothergill Batho, our executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and law-
fully might make, use, exercise, and vend within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN LATHS FOR SUPPORTING BEDDING AND CUSHIONS IN
BEDSTEADS, COUCHES, SOFAS, AND SEATS," upon the condition (amongst others)
that we, the said Edward Peyton and William Fothergill Batho, or one of
us, our executors or administrators, by an instrument in writing under our or
their, or one of our or their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that we, the said Edward Peyton and William Fother-
gill Batho, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, that is to say :-
Our Invention consists in constructing elliptical laths, each separate lath
being composed of two strips of metal united or brought together at their two
ends, and bowed towards the centre, then between the two strips we fix-hoops
of-steel, volute or other metal spring or springs to constitute spring laths
for supporting bedding, cushions, and seats.
Figure 1 of the accompanying Drawings is a side elevation, and Figure 2
is a plan of a spring lath constructed according to our Invention in its simplest
form. a, a', are strips of metal composing the lath of a bow form as shown,
and united at their ends by rivets or otherwise; b, b, are hoops of steel inserted.
between the metal strips a, a'; each hoop decreases in size from the centre
towards the ends as shown in order to correspond with the shape of the metal
strip; c, c, are slots formed at each end of the lath, whereby it is connected
to an ordinary bedstead frame; Figure 3 is a side elevation, and Figure 4 is

page_text: a plan of a lath similar in construction to that just described, with the addi-
tion of springs d, d, at the ends; Figure 5 is a side elevation, and Figure 6
is a plan of a lath in which spiral or helical springs e, e, are employed instead
of hoops b, b, as in the previous Figures; Figure 7 is a side elevation, and
Figure 8 is a plan of a lath in which the spring action is produced by pressure
exerted upon levers united by spiral, helical, or other shaped springs. Detached
views on an enlarged scale are given in side elevation, end view, and plan of
one set of these levers and springs at Figures 9, 10, and 11. The bow-shaped
metal strips a, a, are united by rivets or otherwise to lugs f, f, to which the
levers g, g, g', g', are linked at one end, and linked together at the other as
shown at h, Figure 10; i is a spiral spring laid borizontally between the
levers. Upon pressure being applied to the lath the levers are compressed,
and the spring becomes extended; on the pressure being removed, the spring
returns the levers and lath to their normal state. In practice we insert several
of these spring levers between the bow-shaped metal strips as shown in
Figures 7 and 8, and unite each set of levers by springs k, k, and thus as
well as in the arrangements before described, we constitute spring laths suit-
able for bedsteads, couches, sofas, or other articles to which springs are
required. Sometimes we dispense with the springs k, k.
.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we do not limit ourselves
to the particular form or construction of spring shown and described, for the
same may be extensively varied without departing from our Invention; but
what we claim as our improvements in laths for supporting bedding and
cushions in bedsteads, couches, sofas, and seats is, the construction of laths
consisting of two strips of metal united or brought together at their two ends,
and bowed towards the centre with springs inserted between the metal strips,
all substantially in manner and for the purposes herein-before described and
illustrated in the accompanying Drawings.
:
In witness whereof, I, the said Edward Peyton, for myself and on
behalf of the said William Fothergill Batho, have hereunto set my
hand and seal, this Twentieth day of May, One thousand eight hun-
dred and sixty-two.
EDWARD PEYTON. (L.S.) ·
