PROVISIONAL SPECIFICATION.
Improved Springs.
THOMAS READING 80, Bentinck Streot Birkenhead in the County of Chestor
Engineer do hereby declare the nature of this invention to be as follows:-
The said improved springs are made of any suitable metal-rod or wire, of any
Bize or section, each spring consisting of two rows of coiled spiral parts, at. a
suitable distance apart, and any suitable pitoh, the said coiled spiral parts being of
a suitable,diameter, and formed round or otherwise, one or more coils being used in
Buch parts, these coils may be extended or otherwise. The construction of the said
improved spring is as follows. By taking the rod or wire and forming the first
coiled spiral' part commencing at its base on row No. (1) this coiled spiral part
being made, the rod or wire is then crimped in a suitable manner to the
base of the next coiled spiral part to be formed, and made on row No. (2) this
being made the rod or wire is then crimped back again to row No. (1), and another
coiled spiral part is formed, and made, the rod or wire being so crimped to, and
from each row, a coiled spiral part having been formed and made each time. The
required length of spring being thus made.
The said improved springs are made halfround, flat, V, or any suitable shape in
section, by the crimped parts being so formed.
The said improved springs being applicable to innumerable mechanical,, and
other purposes.
I have applied the said improved springs to my invention, No. 6019, date 1891,
in which I gave a description of the same as applied therein.
The advantages of the said springs are as follows, they are more elastic than any
other springs made of a facsimile strength of rod or wire, less liable to break, take
up little room on the flat, will not jam up with dirt, they will act in a vertical and
lateral direction at the same time, will not weaken by extending and have no
twisting or uncoiling strains.

COMPLETE SPECIFICATION.
Improved Springs.
THOMAS READING 80, Bentinck Street Birkenhead in the County of Chester
Engineer 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 :—
The said improved springs are made of any suitable metal rod or wire, of any
Bize or shape in section. Each spring consists of two rows of coiled spiral parts
formed at a suitable distance apart and any suitable pitch the said coiled spiral
parts are made of a suitable diameter and formed round, or otherwise, one or any
number of coils may be used to form each coiled spiral part, such coils may be
extended, or otherwise, and are connected together by the same rod or wire being
crimped in a suitable manner from one row to the other.
The advantages of the said improved springs are very considerable they are more
elastic than any spring made in the present known shapes, less liable to break, tako
up little space on the Hnt, more evenness of tension, will not jam up with dirt, will
not weaken by extension or compression, will act in a vertical, lateral and trans-
versed direction at the same time and they are made half-round, flat, L, and other

page_text: suitable shapes in section, the orimped parts boing so formed and bent, or twisted
to the required shape.
The springs may be bent to form a complete circle, or any part of a circle or
angle and they are applicable to metallic and other packings for stuffing-boxes,
pistons, piston valves, pump buckets and other mechanical, and domestic appliances.
have applied one form of the said improved springs to my invention. No. 6019, '91.
The construction of the said improved springs.will be more readily understood
with aid of the accompanying drawings in which like letters represent like parts
throughout. I do not bind myself to any particular method in making the improved
springs, they may be made by machinery or otherwise.
Fig. 1, 2, & 3,, are three views of a spring with the coiled spiral parts
extended.
Fig. 4, 5, & 6, are three views of a spring in compression.
Fig. 7, 8, & 9, are three views of a spring flat in section with one coil'in each
spiral part.
Fig. 10, 11, & 12, are three views of a spring L, shape in section.
Fig. 13,, is a plan of a double spring in which shape, any of the before mentioned
springs can be made.
The parts A, and the parts B, are the two rows of coiled spiral parts and C, the
crimped parts. By extending the spring Fig. 1, in the direction of the arrows D,
the parts A, and the parts B, will come nearer together as at E, thus showing the
action of the spring in three directions, the tensiou, as indicated by the arrows D,
the transversed as at E, the vertical as shown by the arrows in Fig. 3.
The compression spring Fig. 4, 5, & 6, will be readily understood the arrows
indicating the direction of compression. The double spring Fig, 13, is simply two
springs twisted and formed into one..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manuer the same is to be performed, I declare that what I
claim is,
1st. The construction application and use of the said improved springs consisting
of the various shapes and forms, as set forth herein before, and shown in the
drawings hereto.annexed.
2nd. The construction, application, and use of springs consisting of the parts A,
and the parts B, in combination with the parts C, substantially as described.
3rd. The construction, application, and use of springs consisting of two rows of
coiled spiral parts in combination with the crimped parts, and with or without other
parts, substantially as described.
