IMPROVEMENTS IN METALLIC OR SPRING MATTRESSES to be as follows:
Year: 1885

page_text: We ISAAC CHORLTON of Blackfriars Street, Manchester, in the County of
Lancaster, Spring Mattress Manufacturer, and GEORGE LAMB SCOTT, also of
Manchester, aforesaid, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN METALLIC OR SPRING MATTRESSES
to be as
follows:-
"
Our Invention relates to the mattresses which are composed of woven or linked
wire or chains or combinations of links, chains, and springs or similar parts
strained upon rectangular wooden frames and the objects of our Invention are to
improve the incans for securing together the members of the frame and for
straining or tightening the woven wire web or the parts constituting the mattress
surface.
The frame of the mattress consists of two side rails and two end bars the latter
being superimposed on the former and the parts being secured together by means
of bolts which pass through the bars and the rails. When so constructed the
frame is deficient in diagonal rigidity and there is an absence of means for readily
tightening the surface. To connect together the parts of the frame we employ
metal plates or brackets which are formed to lock together one plate being secured
to the side rail and the other plate to the end bar at each corner so that the
members of the frame can be quickly put together without the employment of
bolts. The said plates or brackets are made to slide one in or upon another and
projections on one part enter recesses in the other or each part may have a pro-
jection and a recess so that when the mattress is strained the parts are firmly
locked together and at the same time the members of the frame are maintained at
right angles one with another so that the frame has diagonal rigidity. In the
cases wherein it is desirable to make an end bar adjustable upon the rails so as to
provide for the straining of the mattress we form the parts which lock together so
that one part can slide in or upon the other and we provide one part with a screw
which engages with a nut formed in or fixed to the other part as for example we
form upon one plate or bracket a tee headed or vee shaped rib and in the other
plate or bracket we form a tee shaped or vee shaped slot or groove. The said
plates or brackets may be partly box shaped so as to strengthen and give a finish
to the ends of the members of the frame and may be made ornamental in
appearance or they may be made as angle brackets to fit against two or more
surfaces at right angles with each other.

We ISAAC CHORLTON of Blackfriars Street Manchester in the County of
Lancaster, Spring Mattress Manufacturer and GEORGE LAMB SCOTT also of
Manchester aforesaid Engineer do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN METALLIC OR SPRING MATTRESSES
"and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement and accompanying drawings:-
Our Invention relates to the mattresses which are composed of woven or linked
wires or chains or combinations of links, chains and springs or similar parts
strained upon rectangular wooden frames and the objects of our Invention are to
improve the means for securing together the members of the frame and for
straining or tightening the woven wire web or the parts constituting the mattress
surface. The frame of the mattress as at present constructed consists of two side
rails and two end bars the latter being superimposed on the former and the parts
being secured together by means of bolts which pass through the bars and the rails.
When so constructed the frame is deficient in diagonal rigidity and there is an
absence of means for readily tightening the surface. To connect together the
parts of the frame we employ metal plates or brackets which are formed to lock
together one plate being secured to the side rail and the other plate to the end bar
at each corner so that the members of the frame can be quickly put together
without the employment of bolts. The said plates or brackets are made to slide
one in or upon another and projections on one part enter recesses in the other or
each part may have a projection and a recess so that when the mattress is strained
the parts are firmly locked together and at the same time the members of the
frame are maintained at right angles one with another so that the frame has
diagonal rigidity. In the cases wherein it is desirable to make an end bar
adjustable upon the rails so as to provide for the straining of the mattress we form
the parts which come together so that one part can slide in or upon the other and
we provide one part with a screw which engages with a nut formed in or fixed to
the other part as for example we form upon one plate or bracket a tee headed or
vee shaped rib and in the other plate or bracket we form a tee shaped or vee
shaped slot or groove. The said plates or brackets may be partly box shaped so as
to strengthen and give a finish to the ends of the members of the frame and may
be made ornamental in appearance or they may be made as angle brackets to fit
against two or more surfaces at right angles with each other.
And in order that our said Invention may be properly understood we will now
proceed more particularly to describe the same with reference to the accompanying
sheet of drawings.
Fig. 1 represents a side view, Fig. 2 an end view and Fig. 3 a plan view of the
mattress.
The frame (having the aforesaid fixed locking plates applied at the end marked A.
and the sliding parts with adjustable bar at the end marked B.) consists of four
wood rails a. a. being the side rails and b. b¹ the end rails. The rail b. is mounted
upon or secured to the ends of the rails a. by means of interlocking metal fittings.
The rail 6 is arranged to slide upon the rails a. in the manner indicated on a larger

page_text: scale in Fig. 4. To the end of each rail a. is screwed a metal fitting c. which sits
upon the rail and also extends across the end of the same. This fitting is formed
with a tee headed slide c¹ represented in cross section by Fig. 5. Each end of the
rail b¹ is secured within a metal shoe d. which is formed with projections which are
adapted to slide upon the part c¹. A screw e. passes through the upper end of c.
and engages with a screw thread formed in the shoe d. The metallic surface of
the mattress is secured to the two rails b. b¹as shown in Figs. 1 and 3. By turning
the screws this surface can be tightened to any required extent. In the example
this part of the mattress consists of a woven wire sheet connected with the end
rails by means of interposed spiral springs but this may be varied. The connection
of the rail b. with the ends of the rails a is illustrated by Figs. 6 and 7 the former
being a section and the latter an end view of one of the rails a. To the end of
each of the rails a. is screwed or secured a metal fitting f. which extends across the
end of the rail and is formed with an upward projection f¹. Each end of the rail b.
is provided with a metal shoe g. which is formed with a toe g¹ which enters a
recess h. in the projection f¹ and with projections g which enter recesses i. in the
end of the fitting f. To secure the parts together it is only necessary to place one
upon another and then to slide the shoes g. upon the fittings f. until the projections
have entered the recesses. The parts will then be firmly locked together the strain
upon the mattress preventing the parts from coming assunder. The fitting of the
parts together maintains the rectangular form of the frame. The forms of the shoes
and fittings and of the interlocking projections and recesses may be varied.
Although we have described a mattress frame connected together at one end by
fixed interlocking plates or shoes and at the other end by sliding adjustable parts,
we may also construct similar frames connected together at all four corners by
means of the said fixed interlocking plates or shoes, or on the other hand we might
construct mattress frames provided at both ends with the sliding parts and straining
bar hereinbefore described.
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
1. The mattress consisting of the parts secured together and rendered adjustable
substantially as set forth and indicated in the drawings.
2. A mattress frame consisting of four wood rails or members connected together
by means of interlocking metal shoes and fittings and provided with a screw adjust-
ment whereby the fittings on one end rail are caused to slide upon the fittings on
the side rails substantially as and for the purposes set forth.
3. A mattress frame of the indicated construction connected at all four corners
by means of fixed interlocking plates or shoes f. and g. or similarly connected by
means of sliding parts or fittings c and d. with adjusting screws e. for the purposes
and substantially in the manner described and shown.
