page_text: PROVISIONAL SPECIFICATION.
I JOHN WESTGARTH Elmside Bewsey Road Warrington wire manufacturer do
hereby declare the nature of my invention for STRETCHING OR TIGHTENING WOVEN
WIRE OR SIMILAR FORMS OF MATTRESSES to be as follows: -
The end bar or cross rail at either the head or foot is made adjustable, and
provided with screws and nuts or equivalent devices, so arranged that the fabric
can be extended while the working arrangement being inserted in the side rail
cannot therefore be seen.
COMPLETE SPECIFICATION.
I, JOHN WESTGARTH of Elmside, Bewsey Road Warrington in the County of
Lancaster Wire Manufacturer, do hereby declare the nature of my invention for
STRETCHING OR TIGHTENING WOVEN WIRE OR SIMILAR FORMS OF MATTRESS, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
This Invention relates to woven wire and similar forms of mattress and has for
its object the stretching or tightening of such mattresses by a compact arrange-
ment of the tightening apparatus and without risk of the bed clothing or furniture
coming into contact therewith or being soiled thereby.

page_text: And in order that this my said Invention may be more readily understood and
carried into effect I have hereunto appended a sheet of drawings marked with
letters of reference, similar letters denoting similar parts in the various Figures.
Fig 1 represents a longitudinal section of the tightening apparatus through
a b Fig 3.
•
Fig 2 is a cross section of Fig 1 and
Fig 3 a plan of a mattress (part being broken away) showing these Improvements
applied thereto.
At each end of the head or of the foot crossrail or end bar, I provide a means of
adjustment consisting of a clip A to which is secured a prolongation carrying the
nut B capable of reciprocal motion along and within a slot C in a rectangular
casting or forging D inserted in the corresponding end of each side rail. Within
the piece D is mounted a screw E threaded to engage with the nut B through
which it passes in the direction of the length of the side rail. The screw E is
provided with a collar F and a bearing in the end of the box and at the opposite
end it is borne in a suitable bearing formed in the material of the rail or in a
portion of or projection from the piece D so as to prevent end or side motion.
Upon the end of the screw E a square L is formed by which it may be rotated by
a suitable key or handle or some other known arrangement is provided for its
'rotation.
The end bar H to which the adjusting apparatus is not applied may be secured
to the opposite ends of the side rails as indicated at G G.
The position of the movable end bar K is governed by the screws E in the boxes
at the ends of the side rails. When these are rotated in the proper direction the
distance between the cross rails will be increased and the wire mattress M which
is attached to these rails will be correspondingly stretched.
I am aware that screws have already been employed for the purpose of stretching
or tightening woven wire and similar mattresses but such screws have been placed
outside the side rails in an exposed position or in such a position that they are
liable to injury or to soil the bed clothing or furniture.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
Stretching or tightening woven wire and similar mattresses by means of enclosed
screws and nuts substantially as hereinbefore set forth and described.
