IMPROVEMENTS IN MEANS FOR ATTACHING WIRE OR CHAIN MATTRESSES TO IRON OR OTHER BEDSTEADS AND FRAMES
Year: 1884

page_text: We ISAAC CHORLTON of Blackfriars Street Manchester in the County of
Lancaster, Spring Mattress Manufacturer and GEORGE LAMB SCOTT of Manchester
aforesaid Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MEANS FOR ATTACHING WIRE OR CHAIN MATTRESSES TO IRON
OR OTHER BEDSTEADS AND FRAMES" to be as follows:-
Our Invention consists principally of improved means for attaching wire or chain
mattresses to iron bedsteads and for straining such mattresses when in position.
The invention is more particularly applicable to the woven wire mattress for which
Her Majesty's Royal Letters Patent No 2396 of the year 1881 have been granted
to Henry Orth but is also applicable to other forms of mattress. The attachments at
one end of the bedstead consist of two three or any suitable number of small brackets
or clips which are so constructed as that they can be readily caused to engage with the
angle iron member extending across the end of the bedstead, the peculiar form of the
side clips permitting of such ready engagement but preventing the same from
becoming detached when subjected to the strain of the mattress. The metallic strip
which extends across the end of the mattress enters notches or recesses in the said clips
and is held thereby. The opposite end of the bedstead is also furnished with clips
which engage with the angle iron end of the bedstead in a manner similar to that
described. Screws or bolts pass through eyes or projections on the said clips and
engage with nuts which are formed with notches or recesses to retain the metallic
end strip of the mattress. The mattress is thus sustained between the clips at each
end of the bedstead and any desired strain may be put upon the mattress by
turning the bolts which engage with the clip nuts as hereinbefore described. By
the use of our improved attachments we dispense with the necessity for boring
holes in or otherwise weakening the members forming the bedstead ends and the
mattress can be applied and adjusted much more expeditiously than heretobefore.
Where circumstances do not admit of the said metallic strips being inserted into
the recessed or notched clips or nuts we bolt, rivet, or otherwise attach nuts to the
said strips, these nuts engaging with screws or bolts which pass through the clips
on the bedstead ends. The mattress may be strained by turning the bolts at either
or both ends of the bedstead. When it is intended to operate the bolts at one end
only of the bedstead we form the clips at one end with "tee" headed recesses which

adopted to receive the said bolts. When mattresses having wooden end bars are
used we apply metal shoes to the ends of such bars, the said shoes embracing both
sides of the bar and being provided with tapped holes through which pass the
straining bolts from the cud clips. The centres of the said tapped holes in the
shoes are brought as near as possible to the surface of the mattress so as to prevent
the strain of the mattress from canting the end bars. The said metal shoes may
also be used in cases where the mattress is strained upon a wooden frame before
being placed upon the bedstead. The tapped hole in the shoe need not be screwed
throughout its entire length but only for a short distance on each side of the shoe,
the bolt being made of such a length as to engage with the second threaded portion
of the hole when the strain on the mattress has become increased.

Lancaster, Spring Mattress Manufacturer and GEORGE LAMB SCOTT of Manchester
aforesaid Engineer do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MEANS FOR ATTACHING WIRE OR CHAIN MATTRESSES TO IRON
OR OTHER BEDSTEADS AND FRAMES." 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 consists principally of improved' means for attaching wire or chain
mattresses to iron bedsteads and for straining such mattresses when in position.
The invention is more particularly applicable to the woven wire mattress for which
Her Majesty's Royal Letters Patent No 2396 of the year 1881 bave been granted
to Henry Orth but is also applicable to other forms of mattress The attachments
at one end of the bedstead consist of two, three or any suitable number of small
brackets or clips which are so constructed as that they can be readily caused to
engage with the angle iron member extending across the end of the bedstead. The
opposite end of the bedstead is also furnished with clips which similarly engage
with the angle iron end of the bedstead. Screws or bolts pass through the said
clips and engage with nuts upon the metallic end strip of the mattress. The
mattress is thus sustained between the clips at each end of the bedstead and any
desired strain may be put upon the mattress by turning the bolts which engage with
the clip nuts as herein before described. The mattress may be arranged to be
strained by turning bolts at either end or both ends of the bedstead. When
mattresses having wooden end bars are used we apply shoes to the ends of such
bars, the said shoes embracing both sides of the bar and being provided with tapped
holes through which pass the straining bolts from the end clips.
To the end that the description of our Invention may be readily understood we
will refer to the accompanying sheet of drawings wherein Figs: 1. 2. and 3 drawn
to scale illustrate our improved method of straining a metallic mattress upon an
ordinary iron bedstead. In Figs: 1 and 3 the two end angle iron cross rails of
the bedstead are represented in cross section by a the same parts appearing in plan
in Fig: 2. In the same Figs: and in Figs: 4 to 8. b. b. are our improved clips one
appearing about the full size in Fig: 8 Each clip is formed with a foot b¹ which
rests upon the horizontal web of the rail and with a hooked lower end b² which
takes hold of the bottom edge of the vertical web. The clip so formed does not
require any screws or other separate fastenings so that by the use of these clips we
dispense with the necessity for boring holes in or otherwise weakening the members
forming the bedstead ends and the mattress can be applied and adjusted much more
expeditiously than heretofore. It will be seen that the clip cannot yield to the
strain which is put upon it when the mattress is tightened without the lower end
moving in the indicated direction and that such movement is not possible without
some part of the clip breaking. Modifications in the form of the clip appear in the
drawings. In Figs: 1 and 2 the parts are suitable for use in connection with a

page_text: chain and spring mattress. The clips to the right-hand are provided with screws c.
which engage with nuts d. d. In these nuts are formed notches or recesses to
receive the metal end strip e. of the mattress. The form of the clips to the left-
hand is represented on a larger scale in Figs: 4 and 5. The upper end of this clip
is extended forward over the top of the rail and is recessed to receive the cross end
strip e. this strip also resting on a flat part of the clip as clearly shown. The
mattress can be strained to any desired extent by turning the screws c. In Fig: 3
the parts are designed for use in connection with a woven wire mattress. In this
example the parts at both ends are alike so that the mattress can be tightened by
turning the screws at either end of the bedstead or at both ends. In this case the
nuts are riveted or secured to the end strips. Both ends might be provided with
adjusting screws in the example illustrated by Fig: 1 and one end only in Fig: 3.
might be so provided. In some cases when providing only one end with adjusting
screws we use the form of clip represented in Figs: 6 and 7. In this case the clip
is formed with a "tee-headed recess to receive the head of a bolt or connecting
link f. which is attached to or engages with the end strip of the mattress. The
formation of this clip may be varied as regards the means for holding the part f.
Figs 8 and 9 illustrate the construction we adopt when applying mattresses having
wooden end bars. In this example the end bar g. is provided at each end with a
metal shoe h. and the tightening screw c. engages with tapped holes in the two
sides h¹ of this shoe. The centres of the said tapped holes in the shoes are brought
as near as possible to the surface of the mattress so as to prevent the strain of the
mattress from canting the end bars. The said metal shoes may also be used in
cases wherein the mattress is strained upon a wooden frame before being placed
upon the bedstead. At the commencement of the tightening of the mattress the
screw engages only with the threads in the hole on one side of the shoe but as the
strain increases the screw enters the threaded hole on the other side. In cases
wherein the hole for the passage of the screw is made entirely in the metal from
side to side of the bar we do not consider it necessary to tap such hole throughout
its length but we make the hole to clear the screw excepting for a short distance at
each end and these end portions we tap to suit the screw.
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 clips b. formed substantially as and for the purpose set forth and
indicated.
2. The clips b. in combination with the bolts c. and the nuts d. which are formed
to take hold of the metal end strips of a mattress substantially as and for the
purpose set forth and indicated.
3. The combination of the clips b. with the screws engaging with the metal shoes
on the wood end bar of a mattress substantially as set forth and indicated with
reference to Figs: 8 and 9 of the drawings.
Dated this first day of April 1885.
