page_text: of Sweden, Manufacturer, do hereby declare the nature of my invention and
སཔས
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 the manufacture of chairs made principally of round
iron or steel rod or wire.
By using this material and owing to the mode of manufacture it is possible to
produce a chair which while very strong will also be light and have a pleasing
appearance.
In the accompanying drawing
Figure 1 represents the improved chair with the seat removed, and
Figure 2 the seat of such chair.
-
The legs of the chair and its back are made of round iron or steel rod or wire
while the seat is pressed out of a single plate or composed of a frame or hoop of
angle-iron bent to a circle to which the seat proper (a wooden board, an upholstered
cushion, wire gauze or such like) is attached.
Each leg of the chair is made from a round wire or rod bent at one side of the
centre as shown at a so that one portion B is longer than the other portions C.
The two parts are next twisted one upon the other as shown at A for a portion of
their length. Where the wire is bent at a an eye a¹ is formed of greater or
smaller size.
The longer part B of the parts B and C is next bent to form an eye D
immediately at the termination of the twisted part and at the end of each part
is also formed an eye E.
If a seat of wood or wire-gauze or an upholstered cushion is to be used, the legs
of the chair made in the manner described are attached to a ring or hoop F of
angle iron, in such a manner that the eye E of the shorter part C of each leg
(which part is about in axial alignment with the part A) is placed upon the bolt G
traversing a hole in the ring F while the eye E of the longer part B which is bent
at an angle to the part C is placed upon the same bolt as that to which the shorter
part C of the diametrically opposite leg of the chair is secured, suppose that
the chair is provided with four legs, By means of nut H on the inner ends of the
D

page_text: bolts and outside the eyes, the legs are attached to the ring or hoop F. With this
arrangement the longer part B serves as a stay to the shorter part or the leg
proper C.
In order to keep the legs together a wire or wire rope I is passed through the
eyes D and strained, the ends being spliced together.
If the chair has only three legs then the longer parts or stays B are attached by
bolts or rivets to the ring F at a point diametrically opposite that where the
shorter part or the leg C is fastened.
The seat K may if desired be pressed out of a plate into which at the same time
a number of small holes may be punched.
The legs are attached to this seat in the same way as described above.
It is evident that this construction of legs may also be employed for foot-stools,
writing chairs, piano-stools and such like.
The back of a chair is formed of a single wire preferably of steel to render it
flexible.
The material, cut to a suitable length, is folded in the middle and then twisted
as shown at L. The parts are then bent to a circle and again twisted together as
at M. The wires are next bent towards their respective sides and after their
having been bent to circular form they may descend almost parallel to the parts of
the wire previously twisted together. The back formed thus is then attached to the
seat of the chair by means of the same screws or bolts as the hind legs, or the ends
of the wire or rod may themselves be screw threaded and constitute the bolts for
securing the hind legs.
This mode of fastening the legs is employed not only for chairs with four legs
but also for chairs with three legs, one leg being then secured in front under the
seat and the other ones about in the same position as the hind legs of a chair with
four legs.
By the above described construction of the back, it is made slightly elastic,
which is agreeable when using the chair.
A chair of this construction is about as light as a common wooden chair, but it
has the advantage of being much stronger and more durable.
When transported the chair may be dismonted and its sundry parts easily
packed or tied together so that the whole chair requires only a minimum of space.
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:-
A metal chair of which each leg consists of a wire or rod bent near its centre
and twisted at A the part of the said wire or rod which forms the leg proper being
in alignment with the axis of the twisted part A and having its end bent to form an
eye E which is fixed to the seat formed out of a single plate K or to a ring or
hoop F of angle-iron for carrying the seat; the other part or stay B of the leg
being bent to form an eye D and being placed at an angle to the part C and
secured to the seat at the opposite point, the legs of the chair being held together
by means of a wire I passed through the eyes D and then spliced at the ends.
