Improvements in Mattress Frames, and in other Frames intended to
carry Elastic Metallic Mattress Surfaces or Supports.'
We ISAAC CHORLTON of 17 Blackfriars Street Manchester in the County of
Lanca-ter Spring Mattress Manufacturer and (GEORGE LAMB SCOTT of the
same place Engineer do hereby declare the nature of this invention to be ns
follows:-
Our said invention relates primarily to the metallic frames intended to carry
elastic metallic mattress surfaces composed of chain and springs, woven wire, links,
laths and other parts alone or in combination with springs as is well understood.
The invention is however also applicable to the frames of head and foot rests,
couches, ships berths and in short, to all types of bed furniture or to cognate
adjuuets thereof in which a metal frame is used. In applying our invention for
example in the construction of a mattress frame having tubular side and end
members and a mattress surface composed of chain and springs we provide four
corner blocks consisting of plain castings cored or bored near the foot to receive
the ends of the tubular side members or the ends of studs projecting from the ends
of the tubular sides. Thus the two tubular side members carry a block at each
end and to prevent the blocks from coming off the blocks are secured thereto by
pins driven transversely through block and tube or stud, or by other fastening
means.
Near the upper part of the blocks we core or otherwise form holes or recesses
Into the ends
preferably square and standing at right angles to the tubular sides.
of the tubular end members we drive or secure studs having a square extension
projecting from the tubular end and these square extensions enter the aforesaid
square recesses in the corner blocks. Thus the four members of the mattress
frame are easily connected together and without the use of auxiliary bolts or
fastenings. When the elastic metallic mattress surface is hooked or otherwise
attached or strained to or upon the end tubes the pull of the mattress holds the
parts of the frame securely together and this security is enhanced when as for
example is generally the case in chain and spring mattresses, the sides of the mattress
are linked or attached to the tubular sides of the frame. Instead of forming the
end members of the frame from tubing as described they might be of angle iron or
steel in which case the parts carrying the square extensions to enter the recesses in
the corner blocks would be rivetted to the angle ends. In some cases the tube or
angle ends might be made adjustable.

COMPLETE SPECIFICATION.
Improvements in Mattress Frames, and in other Frames intended to
carry Elastic Metallic Mattress Surfaces or Supports.
We ISAAC CHORLTON of 17 Blackfriars Street, Manchester, in the County of
Lancaster, Spring Mattress Manufacturer, and GEORGE LAMB SCOTT of the
same place 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 primarily to the metallic frames intended to carry
elastic metallic mattress surfaces composed of chain and springs, woven wire, links,

page_text: laths and other parts alone or in combination with springs as is well understood.
The invention is however also applicable to the frames of head and foot rests
couches ships berths and in short to all types of bed furniture or to cognate
adjuncts thereof in which a metal frame is used.
To render our invention fully understood we will now proceed to describe the
same more particularly with reference to the annexed sheet of drawings:-
-
Fig. 1 is a side view of a mattress frame made in accordance with our
invention.
Fig. 2 is a plan of Fig. 1.
Figs. 3 and 4 show the corner block to an enlarged scale.
Fig. 5 shows the plug in the tube fitted to enter the corner block.
Figs. 6 and 7 are perspective views of the block and the ends of the tubular
sides and ends.
Figs. 8 to 11 illustrate modifications in our invention.
In applying our invention for example in the construction of a mattress frame
similar to the frame illustrated by Figs. 1 and 2 having tubular sides a end
members and a mattress surface c composed of chain and springs or other clastic
fabric we provide four corner blocks consisting of plain castings as shown at
Figs. 3 and 4 cored or bored near the foot to receive the ends of the tubular side
members a or the ends of studs projecting from the ends of the tubular sides.
Thus the two tubular side members a carry a block dat each end and to prevent,
the blocks from coming off, the blocks are secured thereto by pins e driven trans-
versely through block and tube or stud or by other fastening means.
Near the upper part of the blocks d we core or otherwise form holes or recesses/
preferably square and standing at right angles to the tubular sides a. Into the
ends of the tubular end members we drive or secure studs g having a square
extension projecting from the tubular end and these square extensions enter the
aforesaid square recesses in the corner blocks. Thus the four members of the
mattress frame are easily connected together and without the use of auxiliary bolts
or fastenings. When the elastic metallic mattress surface c is hooked or otherwise
attached or strained to or upon the end tubes & the pull of the mattress holds the
parts of the frame securely together and this security is enhanced when as for
example is generally the case in chain and spring mattresses the sides of the
mattresses are linked or attached to the tubular sides of the frame. Instead of
forming the end members of the frame from tubing as described they might be of
angle iron or steel in which case the parts carrying the square extensions to enter
the recesses in the corner blocks would be rivetted to the angle ends. Such a
construction is shown at Fig. 10 where the square or rectangular extension g' is
formed in one piece with the bracket y to which the angle end is rivetted as
clearly shown in the fig.
Figs. 8 and 9 show a modified form of the corner bracket which might be used
in conjunction with the construction shown at Fig. 10.
Fig. 11 shows the application of our invention to a mattress frame having sides a
of wood. In this case the corner block d constitutes or may constitute a shoe
fitting on the end of the wooden side and having a rectangular recess to receive
the similarly formed extension from the tubular or angular end.
Although we have referred to the recesses in the blocks and the extensions from
the ends as being square or rectangular in shape it will be evident that these
recesses and extensions might be triangular, polygonal, oval or of other suitable
regular or irregular form, or they might be round with a feather and groove or
feathers and grooves to prevent the extensions from turning in the recesses.
some cases the tube or angle ends might be made adjustable.
In
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The improved mode of connecting together the sides and ends of mattress

page_text: frames and cognate furniture substantially as hereinbefore described and as
illustrated.
2. As means for connecting together the sides and ends of mattress frames and
the like the corner blocks d fitted to receive or fixed to the ends of the side
members and having square or other suitably shaped recesses to receive the corre-
spondingly formed extensions from the plugs or brackets entering the tubular or
supporting the angle ends substantially as described and shown.
