We ISAAC CHORLTON of Blackfriars Street Manchester in the County of Lancaster,
Spring Mattress Manufacturer and GEORGE LAMB SCOTT also of Manchester afore-
said, Engineer, do hereby declare the nature of this Invention to be as follows:-
Our said Invention relates chiefly to the construction of iron bed frames and
bedsteads and has for its object to dispense with the usual dovetail attachments
employed to connect together the members of the bedstead at the four corners as is
well understood. Owing to the difficulty of obtaining a perfect fit the said dovetails
are seldom sufficiently secure to prevent relative movements of the parts and to keep
the ends of the bedstead exactly at right angles horizontally and vertically to the side
members, while owing to variations arising in moulding and casting the parts intended
to come together and which should be interchangable are not always so. In addition
to these defects the dovetail is inherently weak and is frequently broken. According
to our invention we form the corner casting or bracket of the bedstead, which usually
contains the female dovetail recess or recesses, with a projecting ledge or rectangular
block and we cast, screw or otherwise secure or insert a bolt or pin into the said
corner bracket or we pass a loose bolt from the outside through the corner bracket
and upright and preferably projecting from or through the said rectangular block.
The casting which is usually formed with the male dovetail and which is attached to
the side members, or to the side and end members where such casting is intended to
carry both, is cast with a recess into which the aforesaid rectangular block enters, an
accurate fit not being necessary. The bolt or pin projecting from or through the
corner bracket passes through a hole in the recessed casting and the two castings are
held firmly together by a nut screwed upon the bolt or by a tapered cottar driven
through a slot in the pin when such is used. The recessed casting rests upon the ledge
or on the top of the block on the corner bracket so that the bedstead can be put
loosely together preparatory to the screwing up of the nuts or the driving in of the
cottars so that only one person is required for the operation. When the castings are
brought closely together by the nuts or cottars the contact of the extended fitting

page_text: surfaces of the respective castings makes a firm joint and secures absolute perpendicu-
larity of the ends of the bed and also prevents the bod from being twisted in any
direction. Instead of forming rectangular blocks on the corner brackets as aforesaid
we might form the said blocks on the castings to which the side and end members are
attached, and correspondingly recess the corner brackets or we might form ledges or
projections on one casting or bracket which would enter corresponding recesses in the
other casting or bracket so that the two castings would interlock and support each
other when placed together preparatory to bolting or securing. In cases where both
the side and end members of the bedstead are secured directly to the corner brackets,
these brackets are correspondingly formed to take both the side and end recessed castings,
but where the recessed castings which carry the side members are also arranged to
carry the end angle irons or members, only one face of the corner bracket is prepared
to receive the recessed casting. Where the corner casting is in direct connection with
both side and end members, we might attach the side members by means of our
improved arrangement and utilize the old dovetail joint to secure the end members in
position. The side and end members may be of angle iron or of iron tubing, or they
may be composed either wholly or partially of wood, the recessed castings being
correspondingly formed to receive whatever class of side and end member may be
used. We prefer to make the aforesaid improved joint of constant proportions so that
the parts may be interchangable not only for the same size and class of bedstead but
also for bedsteads of different types of construction.

Improvements in the Construction of Bed Frames and Bedsteads.
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 this Invention 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 said Invention relates chiefly to the construction of iron bed frames and
bedsteads and has for its object to dispense with the usual dove-tail attachments
employed to connect together the members of the bedstead at the four corners as is
well understood. Owing to the difficulty of obtaining a perfect fit the said dovetails
are seldom sufficiently secure to prevent relative movements of the parts and to keep
the ends of the bedstead exactly at right angles horizontally and vertically to the side
members, while owing to variations arising in moulding and casting, the parts intended
to come together and which should be interchangable are not always so. In addition
to these defects the dovetail is inherently weak and is frequently broken. According
to our invention we dispense with the said dovetails and unite the bedstead at the
corners by means of fittings having flat surfaces with interlocking projections and
recesses the parts being held together by bolts or screws.
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 annexed sheet of
drawings.
Fig. 1 is a side view of one corner of a bedstead fitted together in our improved
manner. Fig. 2 is a view of the joint from the end of the bed. Fig. 3 is a plan of
the upright end pillar of the bedstead with its corner fitting detached from the fitting
belonging to the side and end member of the bedstead, which latter is shown at
Fig. 4.
Fig. is a face view of the corner fitting shown at Fig. 3. As clearly indicated
by these figures the corner piece a is cast on or secured to the upright end pillar b.
The face of the corner piece a is flat and carries a projection a' from which a bolt c
extends. The bolt c passes through a hole in the bracket d and the said bracket is
also recessed as clearly shown at Fig. 4 to receive the projection a¹ seen in Fig. 3.
The said projections and recesses may however be dispensed with and the meeting faces
left perfectly flat. When the bracket d and corner piece a are fitted together and
secured by a nut e on the bolt c the flat faces thus held in contact prevent the
bedstead from being twisted and secure absolute perpendicularity of the end pillars b.
Instead of a nut e a tapered cottar or a pin might be driven through the bolt c when
it has been passed through the bracket d.
face on the corner piece a is required, as
side member but also the angle iron end
the bracket is cast with a plug which
In the example illustrated only one fitting

member g. To receive the side member ƒ,
enters the tubular side member fand is

angle iron end member g to which the mattress i is attached in the usual manner.
When the mattress is strained and secured to the end members in position, nothing
remains but to bolt the brackets d to the corner pieces a and the bedstead carrying its
mattress is complete thus forming a simply connected and strong bedstead which is
not liable to the weaknesses and distortions of similar bedsteads connected together by
dove-tail fittings.
We prefer in the manufacture of our invention to make the improved joint of
constant proportions so that the parts may be interchangable not only for the
same size and class of bedstead but also for bedsteads of different types of
construction.
Having now particularly described and ascertained the nature of this said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
In the construction of bedsteads having tubular sides and ends of angle iron attached
at each corner to a bracket which carries both side and end members forming the said
corner brackets with faces so that they can be bolted to corresponding faces on the
corner pieces carried by the upright pillars of the bedstead end, the said faces being
either flat or formed with recesses and projections substantially as hereinbefore
described and shown.
