BEDSTEADS
PROVISIONAL SPECIFICATION left by the said Isaac Chorlton at the.
Office of the Commissioners of Patents on the 4th December 1883.
ISAAC CHORLTON of the firm of Chorlton & Dugdale of Manchester in the
County of Lancaster, Spring Mattress Manufacturers "IMPROVEMENTS IN OR
APPLICABLE TO SPRING MATTRESSES AND IN THE METHODS OF SECURING THE SAME
TO MATTRESS FRAMES AND BED-STEADS
"
These improvements relate to that class of spring mattress in which an elastic
surface of wire is stretched or distended upon a frame-work-and have for their
object a simple and effective method of securing the net-work in position upon the
frame or bed-stead-whereby the said net-work can be readily disconnected and
folded up for carriage and the frame-work can more easily be taken to pieces than
heretofore and whereby the tension of the net-work can be adjusted to any desired
degree.
Now this invention consists in affixing the extremities of the wire net-work at
each end to a bar or bars of iron of flat, round, L or T iron-or iron of any other
suitable strength and cross-section-the bar or bars at one end being provided in
the case of an iron bed-stead with headed studs adjustable or otherwise which take
into corresponding holes and slots in the angle-iron forming the head or foot rail
of the bed-stead or secured thereto in any other suitable detachable manner-and
the other bar which is at the opposite extremity of the net-work being provided
with feinale screws or fixed nuts into which screw two or more set screws passing
through the angle iron at the other end of the bed-stead and by means of which
screws the tension or degree of elasticity of the net-work can be adjusted to any
desired extent as aforesaid,

page_text: In the case of a wooden frame-work being employed instead of conuecting the
transverse rails to the sides of the wooden frame-work by means of bolts passing
through holes formed both in the transverse rails and the sides of the frame-work
as heretofore and whereby of necessity the nuts have to be removed from the bolts
in order to take the frame-work to pieces I form slots in or near the extremities of
the sides or transverse rails to receive the bolts which in this case only pass through
holes in either the transverse rails or sides and thus in taking the frame-work to
pieces all that is necessary is to loosen the nuts and the frame-work can thon be
drawn asunder. The iron bar in this case is preferred to be secured to the foot or
head rail by hooks, brackets or studs, behind which the said bar is passed or
secured thereto in any other suitable detachable manner and the bar at the other
end is similarly connected as hereinbefore described to the transverse rail and is
provided with tension screws passing through iron brackets rising from and secured
to the extremities of the sides of the wooden frame-work
These improvements are equally applicable to what is known as the spiral or
woven wire mattress or to the Excelsior Mattress (Woods Patent N° 3419
AD 1871.) or to any other similar class of mattress which requires to be distended
upon its frame-work
Another part of this invention relates to the construction and application of an
irou or other metal border to the extremities of the wires or coils used in the
construction of spiral or woven wire mattresses whereby the ends of the wires or
coils are firmly secured in position and prevented being drawn out of place when
the tension is put upon the net-work and whereby the connecting of the net-work
to the frame-work or bedstead is facilitated as aforesaid
In carrying out this part of my invention. I form one or more corresponding
grooves and projections or corresponding serrations or corrugations in a pair of iron
plates which constitute the border aforesaid and between which I clamp the ends
of the wires or coils forming the ends of the net-work and I prefer that the set
screws or bolts for securing the plates together shall also be utilised for securing the
female screws or nuts used as hereinbefore described for adjusting the tension of the
elastic surface-in cases where such screws or nuts are not cast or formed in one
piece with the clamping plates.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, and of
an Order of the Lord Chancellor, filed by the said Isaac Chorlton in the Patent
Office on the 9th June 1884.
ISAAC CHORLTON of the firm of Chorlton & Dugdale, of Manchester in the
County of Lancaster Spring Mattresses Manufactures "IMPROVEMENTS IN OR
APPLICABLE TO SPRING MATTRESSES AND IN THE METHODS OF SECURING THE SAME
TO MATTRESS FRAMES AND BED-STEADS
"
These improvements relate to that class of spring mattress in which an elastic
surface of wire is stretched or distended upon a frame-work, and have for their
object a simple and effective method of securing the net-work in position upon the
frame or bed-stead whereby the said net-work can be readily disconnected and
folded up for carriage and the frame-work can be more easily taken to pieces than
heretofore and whereby the tension of the net-work can be adjusted to any desired
degree.
Now this invention consists in affixing the extremities of the wire net-work at
each end to a bar or bars of iron of flat, round L or T iron, or iron of any other
suitable strength and cross-section as hereinafter described.
In the accompanying drawings Fig 1 represents a perspective view of a bed-
stead and mattress having my improvements applied thereto and Fig 2 is a side
sectional view and Fig 3 a plan (drawn about 3/4 full size) of a portion of the
same spring mattress and shewing my improved mode of securing the same to the
angle iron of the bed-stead. In all the views (a) is the wire-net-work forming the
spring mattress or elastic surface and which in accordance with this invention is
affixed at each end to the wrought iron bars (b) and (b) the bar (b) is provided as
illustrated with healed studs (c) which take into corresponding holes and
slots (c¹) formed in the metallic clips or brackets (d) which grasp the bottom of the
angle iron (e) as illustrated or such holes and slots may in the case of new bed-
steads be formed directly in the angle iron (e). The other bar (6¹) at the opposite
extremity of the net-work (a) is provided with female screws or fixed nuts (f) into .
which screw two or more set-screws (g) passing through the angle iron at that
end of the bed-stead and by means of which screws the tension or degree of
elasticity of the net-work can be adjusted to any desired extent as aforesaid.
In the case of a wooden frame work being employed as indicated by side view
in Fig 4 instead of connecting the transverse rails (h) to the sides (i) by means of
bolts passing through vertical holes formed both in the said rails and sides and
whereby of necessity the nuts have to be removed from the screw bolts in order to
take the frame-work to pieces I form slots (j) (seen more clearly in plan Fig 5) in or
near the extremity of the sides (2) (or such slots may be formed in the transverse
rails) to receive the bolts (k) which in this case only pass through vertical holes in
the transverse rails (h) (or such holes may be formed in the sides when the rails
are slotted as aforesaid) and thus in taking the framework to pieces all that is
necessary is to loosen the nuts of the screw-bolts (k) and the framework can then
be drawn asunder. The iron bar (m) in this case is preferred to be secured to the
foot or head rail by similar metallic clips (1) to those used for securing to the angle
iron as hereinbefore described and which are screwed or spiked to the rail, or
hooks, brackets or studs may be employed behind which the said bar is passed or
such bar may be secured thereto in any other detachable manner.
The bar (m²)
at the other end of the wire net-work is similarly connected as hereinbefore
described to the other transverse rails which is provided with tension screws (n)
passing through iron brackets (o) rising from and secured to the extremities of the
sides of the wooden framework as illustrated,

page_text: These improvements are equally applicable to what is known as the spiral or
woven wire mattress or to the Excelsior Mattress (Wood's Patent No 3419 A.D. 1871)
or to any other similar class of mattress which requires to be distended upon its
frame-work. Another part of this invention relates to the construction and
application of an iron or other metal border to the extremities of the wires or coils
used in the construction of spiral or woven wire mattresses whereby the ends of
the wires or coils are firmly secured in position and prevented being drawn out of
place when the tension is put upon the net-work and whereby the connecting
of the net-work to the frame-work or bed-stead is facilitated as aforesaid. A short
length of this improved description of border is illustrated in front view in Fig, 6
and by side sectional view in Fig 7. In carrying out this part of my invention
I form one or more corresponding grooves (p) and projections (q) or corresponding
serrations or corrugations in a pair of iron plates (7) and (1) which constitute the
border aforesaid and between which plates I clamp the ends of the wires or coils
forming the ends of the net-work and I prefer that the set-screws or bolts (8) for
securing the plates together shall also be utilised for securing the female screws or
nuts (t) used as herein before described for adjusting the tension of the elastic
surface in case whère such screws or nuts are not cast or formed in one piece with
the clamping plates. It will be observed that the back part (u) of the upper plate
overhangs the corresponding part of the lower plate and thus serves to hide or
sheild from view the ragged ends of the wires or coils.
Having thus particularly described and ascertained the nature of this my said
invention together with the best methods with which I am acquainted for carrying
the same into practical effect I wish it to be distinctly understood that I do not
confine myself to the precise details relative proportions or dimensions of the
various parts of my improved framework and mechanism for securing in position
and adjusting the tension of spring mattresses herein before described and illustrated
on the accompanying drawings as the same may be considerably varied without
departing from the invention but what I do claim is-1st The mode or method of
securing the extremities of wire net-work forming spring mattresses to the head
and foot rails of bed-steads or to the ends of their framework substantially as and
for the purpose herein before described and illustrated on the accompanying
drawings. 2nd The improvements in or applicable to the wooden frame of spring
mattresses substantially as and for the purposes herein before described and
illustrated on the accompanying drawings. 3rd The improved arrangements and
construction of clamping plates forming a border for securing the extremities of
the wires or coils used in the Construction of spiral or woven wire mattresses to
the bed-stead or framework substantially as and for the purposes hereinbefore
described and illustrated on the accompanying drawing.
In witness whereof I the said Isaac Chorlton have hereunto set my hand and
seal this 4th day of June in the year of our Lord 1884.
