PROVISIONAL SPECIFICATION.
Improvements in Springs for Seats and like purposes.
I, JOHN SMITH MIDDLETON, of 105 Dale Street Hulme, Manchester, in the
County of Lancaster, Agent, do hereby declare the nature of this invention to be
as follows:-
This invention relates to seat springs that are or may be applicable to the seats of
chairs, sofas, railway carriages, and the like, spring mattresses and similar uses. And
the object of this invention is to obtain elasticity equally near the frames as in the:
centre of said scats or mattresses.
In the accompanying sheet of drawings,
Fig. 1 is the side view of a seat spring according to my invention which is shewn,
applied in two forms of seats, Fig. 2. representing a seat frame for a chair and
Fig. 3. a seat frame for a sofa, or any like object.
In this invention I form a seat spring such as b in which the end of each spring
is S shaped.
a
I attach the ends to the frame a either by the means of a pin C fitted in the
have
may
said frame and working in a slot in each of the ends b, or the ends b
strip of leather attached thereto and said leather nailed to the inner edge a¹ of
the frame a to keep the springs in the position required. Or they may be nailed.
or screwed on a frame without the leather attachment.
The number, of springs employed may be varied to suit the size of the article:
to which it is applied.
In Fig. 1, two springs are shown placed each way, but for small sized seats one.
spring only placed each way may be employed.
In Fig. 2, two longitudinal springs of a like form at their ends are shown in
combination with a greater or less number of transverse springs. The aforesaid.
springs may be secured to each other by a screw such as b².
I also claim that these springs can be made the shape required for any seat or
back of seat and that they can be taken out if one be broken and replaced without
removing the padding or upholstering.
That they will give a better, cheaper, and more durable seat than any yet
invented. Only one half of the padding material now used will be required to..
attain the same result.
Dated this Seventh day of March 1893.

COMPLETE SPECIFICATION.
Improvements in Springs for Seats and like purposes.
I, JOHN SMITH MIDDLETON of 105 Dale Street, Hulme, Manchester, in the
County of Lancaster Agent 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 :-
This invention relates to springs that may be applied to chair seats, chair backs,.
sofas, couches, mattresses, railway carriage seats and backs, and similar uses.
The object of this invention is to obtain elasticity equally near the frames, as in.
the centre of said seat, mattress or other article.

page_text: I attain this object by the S shaped form of the ends of the spring as herein
after described and as shown in the accompanying sheet of drawings, in which
Figs. 1 and 2 are edge views of a spring in accordance with this invention;
Fig. 3 is a plan of the same;
Figs. 4, 5, 6 and 7 represent plans of seats;
Fig. 8 represents a section of a seat and back applicable to railway carriage or
other like forms of seats.
In the several views shown similar letters refer to similar parts.
In this invention I form a seat spring such as in which the end of each spring
is S shaped as shown on drawing: I attach the ends to a frame such as a, by
means of a pine which may be fitted in the said frame either at the top as in
Fig. 1, or on the side as in Fig. 2 and working in the slot in each of the ends 6¹, or
the ends may have a strip of leather attached thereto, and the said leather
nailed to the inner edge a¹ of the frame a, to keep the springs in the position
required.
The number of springs employed may be varied to suit the size of the article
to which it is applied.
In Fig. 4 two springs are shown placed each way, but for small sized seats, one
spring only placed each way as in Fig. 5 may be employed.
In Fig. 6 two longitudinal springs of a like form at their ends are shown in
combination with a greater or less number of transverse springs.
The aforesaid springs may be secured to each other by means of a screw
such as b².
In seats that have rounded or curved ends as in Fig. 8, I attach semi-springs, or
springs with one end only formed S shaped.
Fig. 9 represents a section of a railway carriage seat and back constructed with
springs having their ends formed in accordance with this invention.
By these means a spring may be taken out if broken, and replaced without
removing the padding or upholstering, and less material is required for the purpose
of upholstering.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. Springs formed with S shaped ends, that may be employed for chair seats,
chair backs, sofas, couches, mattresses, railway carriage seats and backs, and like
uses, and attached either to the top or side of the frames of the seat or back to
which they may be applied, in the manner and for the purpose substantially as
herein before described.
2nd. Springs formed with one end shaped, that may be employed to form the
curved or rounded ends of chair seats, sofas, couches, or other articles, in the
manner and for the purpose substantially as herein before described.
Dated this 7th day of December 1893.
