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 to be as follows:-
Our said Invention relates more particularly to the angle iron members which con-
stitute the ends of certain types of mattress and bed frames and to which the woven
wire chain or other elastic material or fabric is hooked or attached as is well under-
stood. Hitherto in applying such ends it has been the custom to employ angle iron
of the ordinary section which owing to the thickness of its edge has rendered difficult
the punching or drilling of the holes made to receive the attaching rivets, bolts, hooks,
springs, rings or links besides increasing the size of the said attachments. In addition
to this disadvantage the ordinary angle iron section is not well calculated to resist the
distorting strain of the mattress and becomes frequently bent out of shape. To assist
in obviating the foregoing defects we have devised a novel section of angle member
which may be made of iron but which we prefer should be made from steel for the
sake of lightness and strength. Our improved section is rolled with an edge of
reduced thickness at the part where the attaching rivets, hooks, springs, rings or
links are applied the thickness of the reduced portion of the edge being equal to say
one half of the thickness of the rest of the section or it might be more or less.
reduction may be effective from one or from both sides of the metal so long as a strip
of reduced thickness is left along the edge of sufficient breadth to take the holes
through which the attachments are passed. By providing this strip of reduced
thickness the labour of punching the holes is considerably decreased and the bulk of
the attaching rivets, rings, hooks, springs or links is also minimised. In addition to
The

page_text: this reduced portion our improved section is also rolled with a raised strip, projection,
flange or lip on the outside of the angle which confers greater rigidity upon the
member and enables it better to withstand the bending strain of the mattress.
Although we have referred to our improved section as being more especially suitable
for the end members of a bed or, mattress frame we wish it to be understood that it
may also be applied at the sides or in other situations. The improved angle iron
section is intended to be applied to all forms of bed and mattress frames, ships berths,
couches, rests, chairs and the like wherein metallic or other resilient or elastic material
or fabric is used and attached in the manner set forth.

Improvements in the Manufacture of Bed, Mattress, and other
similar Frames.
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 more particularly to the angle iron members which con-
stitute the ends of certain types of mattress and bed frames and to which the woven
wire, chain or other elastic material or fabric is hooked or attached as is well under-
stood. Hitherto in applying such ends it has been the custom to employ angle iron of
the ordinary section which owing to the thickness of its edge has rendered difficult the
punching or drilling of the holes made to receive the attaching rivets, bolts, hooks,
springs, rings, or links besides increasing the size of the said attachments. In addition
to this disadvantage the ordinary angle iron section is not well calculated to resist the
distorting strain of the mattress and becomes frequently bent out of shape. To assist
in obviating the foregoing defects we have devised a novel section of angle member
which may be made of iron but which we prefer should be made from steel for the
sake of lightness and strength.
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 combined sectional and perspective view of our improved
section of angle steel. As shown in the drawings we roll the section with an edge of
reduced thickness at the part a where the attaching rivets, hooks, springs, rings or
links are applied, the thickness of the reduced portion of the edge being equal to say
one half of the thickness of the rest of the section or it might be more or less. The
reduction a may be effected from one or from both sides of the metal so long as a
strip a of reduced thickness is left along the edge of sufficient breadth to take the
holes through which the attachments are passed. By providing this strip of reduced
thickness the labour of punching the holes is considerably decreased and the bulk of
the attaching rivets, rings, hooks, springs or links is also minimised. In addition to
this reduced portion a our improved section is also rolled with a raised strip, pro-
jection, flange or lip c on the outside of the angle which confers greater rigidity upon
the member and enables it better to withstand the bending strain of the mattress.
Fig. 2 is a view of a modified form of our improved section in which the reduced
thickness at the edge a is obtained by a gradual reduction of the thickness of the
upper web of the angle steel section as shown. Although we have referred to our
improved section as being more especially suitable for the end members of a bed or
mattress frame we wish it to be understood that it may also be applied at the sides or
in other situations. The improved angle iron or steel section is intended to be applied

page_text: to all forms of bed and mattress frames, ships berths, couches, rests, chairs and the
like wherein metallic or other resilient or elastic material or fabric is used and attached
in the manner set forth.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is :-
(1) The improved section of angle iron or steel having a reduced thickness,
portion or lip a in the upper web for the reception of the holes and a raised strip or
projection e for the purpose of stiffening the section substantially as described and
shown at Fig. 1 of the drawings.
(2) The improved section of angle iron or steel of the form shown at Fig. 2 of the
drawings.
