IMPROVEMENTS IN MATTRESSES
Year: 1882

page_text: PROVISIONAL SPECIFICATION left by the said Samuel Kerr Ibbetson at
the Office of the Commissioners of Patents on the 5th December 1882.
SAMUEL KERR IBBETSON, of Southsea, in the County of Hants, "IMPROVEMENTS
IN MATTRESSES,"
The improvements relate to obtaining a strengthened or tied underframe to
wire woven mattresses, whereby the straining or tightening of the adjustable
frame-work carrying the wire woven part, is prevented from bending or curving
upwards the underframe. For this purpose I connect or tie the end supports or
other parts of the underframe with two or more metal wires, say one on each side,
and I place one or more straining pieces under the underframe so that they bear on
the wires; by this means I can while making the framing and supports lighter,
add to the durability of the article and tightening capacity of the wire woven part.
Of course mattresses made with sacking or canvas or other material capable of
being stretched can be similarly.treated. .

SAMUEL KERR IBBETSON, of Southsea, in the County of Hauts,
IN MATTRESSES,"
"IMPROVEMENTS
The improvements relate to obtaining a strengthened or tied under-frame to
wire woven mattresses, whereby the straining or tightening of the adjustable
framework carrying the wire woven part does not cause the under-frame to bend
or curve upwards. For this purpose I connect or tie the end supports or other
parts of the under-frame with two or more metal wires say one on each side and I
place one or more straining pieces under the underframe so that they bear on the
wires; by this means I can while making the framing and supports lighter, add to
the durability of the article and the tightening capacity of the wire woven part.
Of course mattresses made with sacking or canvass or other material capable of
being stretched can be similarly treated.
The accompanying drawings will illustrate a convenient mode of performing my
improvements, but the small matters of detail may be varied without departing
from the nature of my invention.
Fig 1 is a side elevation, and Fig 2 a plan-A is an end piece carrying the wire
woven mattress K. A is made in one or two pieces and receives and holds one
end of the mattress the other end being fixed on C. P are metallic shoes into
which A is fastened at each end, said shoes travelling on the main side of under-
frame when the adjusting or tightening bolts M are moved. or screwed up-Cand B
are end,pieces of under-frame supported on and in metallic fittings as shown and
having four legs or feet as at D and E through which is passed two rods L fitted
with screwed nuts as at F and G. At H on each side of under-frame is a depending
strainer piece against which the rods are stretched by turning the nuts. It will
be seen that the mattress K. can be adjusted to any reasonable extent without
breaking or curving the under-frame by also adjusting the nuts on the straining
rods L.
•
I claim the combination of adjustable and tensible mattresses with a tied
or tensile under-frame substantially as described and for the purposes.set forth.
In witness whereof, I the said Samuel Kerr Ibbetson have hereunto set my
hand and seal this 30th day of May A.D. 1883.
