IMPROVEMENTS IN METALLIC SPRINGS
Year: 1884

page_text: I, WILLIAM BUCKLEY of Millsands, Sheffield, in the County of York, Engineer,
do hereby declare the nature of the said invention for "IMPROVEMENTS IN
METALLIC SPRINGS," to be as follows:-
This Invention-relates to a new construction or manufacture of metallic springs
applicable for all purposes wherein durable elastic metallic springs are required or
used, the special object of the Invention being the production of a spring or
springs that will expand, contract or compress, and at the same time will be very
durable and elastic.
This improved spring is made of steel phosphor-bronze, brass, or of other suitable
metallic material or compound, and of a flat, square, round, oval, or of any desired
form or section.
According to one method of practically carrying out my invention I take a rod,
bar or plate of the desired metallic material and section, and this rod, bar or plate
I cut or slit transversely or crosswise from one edge or side and as near to the
other edge or side as necessary or desirable.
The cuts or slits are made from both edges or sides of the rod bar or plate,
every alternate cut or slit can be made from the same edge or side, or two or
more consecutive cuts or slits may be made from the same edge or side.
The cuts or slits can be made straight across the rod, bar or plate at right angles
to its edge or side, or in a slanting angular or other convenient direction; they
may be parallel or all of one width, or narrower at the top and wider at the
bottom, or vice versa. The corners of the cuts or slits are made either angular
circular or of other suitable shapes, and the cuts or slits may be made at regular
or certain, or at varied or irregular, distances from each other, and they may also
be of various widths and shapes.
The rod, bar or plate being cut or slit as described to any required length or,
lengths, forms a spring of a strong, elastic, and efficient character, and this too
whether the spring or springs be bent in a circular form or be required to be used
in a straight form or otherwise.
According to another method of carrying out my invention in practice the spring
can be cast with the cuts or slits ready made in it, the operation of cutting or
forming the cuts or slits is then unnecessary. The spring by this mothod of
"

page_text: manufacture may be cast in a circular or semicircular form, or in a. length or
lengths, or in segments, and afterwards be bent or arranged into a circle or other
desired form.
•
The springs made according to this invention may be bent or dished lengthwise
in such a manner that the section thereof will show a curved or angular form and
they may also be transversely dished at regular or irregular distances, the edges
thereof may be made even or parallel, or may be so made as to form an uneven or
undulating line, or portions of the edges may be cut away so that some parts of the
spring will stand or be higher than the rest or other parts.
These springs can be made either in one entire length or circle, or they may be
made in any suitable number of lengths, segments or parts, and either straight,
parallel, curved or otherwise, and if necessary any suitable number and sizes of
springs may be arranged to be used together instead of one.
Springs made as hereinbefore described will be found very suitable for expanding
contracting or compressing in a circular or other form and may be used for all
purposes where metallic springs are required.
improvements in Metallic Springs.
I WILLIAM BUCKLEY of Millsands Sheffield in the County of York Engineer
do hereby declare the nature of the said invention for IMPROVEMENTS IN
METALLIC SPRINGS," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement in writing,
and on reference to the accompanying sheet of drawings, that is to say :-
This Invention relates to a new construction or manufacture of metallic springs
applicable for all purposes wherein durable elastic metallic springs are required or
used, the special object of the invention being the production of a spring or springs
that will expand contract or compress, and at the same time will be very durable
and elastic.
This improved spring is made of steel phosphor-bronze, brass, or of other suitable
metallic material or compound, and of a flat, square, round, oval, or of any desired
form or section.
According to one method of practically carrying out my invention I take a rod,
bar, or plate, of the desired metallic material and section, and this rod bar or plate
I cut or slit transversely or crosswise from one edge or 'side and as near to the
other edge or side as necessary or desirable,

page_text: The cuts or slits are made from both edges or sides of the rod bar or plate, every
alternate cut or slit can be made from the same edge or side, or two or more
consecutive cuts or slits may be made from the same edge or side.
The cuts or slits can ho made straight across the rod bar or plate at right angles
to its edge or side, or in a slanting angular or other convenient direction; they
may be parallel or all of one width, or narrower at the top and wider at the
bottom or vice versa. The corners of the cuts or slits are made either angular
circular or of other suitable shapes, and the cuts or slits may be made at regular or
certain or at varied or irregular distances from each other, and they may also be of
various widths and shapes.
The rod bar or plate being cut or slit as described to any required length or
lengths forms a spring of a strong elastic and efficient character and this too
whether the spring or springs be bent in a circular form or be required to be used
in a straight form or otherwise.
According to another method of carrying out my invention in practice, the
spring can be cast with the cuts or slits ready made in it, the operation of cutting
or forming the cuts or slits is then unnecessary. The spring by this method of
manufacture may be cast in a circular or semicircular form, or in a length or
lengths, or in segments and afterwards be bent or arranged into a circle or other
desired form.
The springs made according to this invention may be bent or dished lengthwise
in such a manner that the section thereof will show a curved or angular form and
they may also be transversely dished at regular or irregular distances, the edges
thereof may be made even or parallel or may be so made as to form an uneven or
undulating line, or portions of the edges may be cut away so that some parts of
the spring will stand or be higher than the rest or other parts.
These springs can be made either in one entire length or circle or they may be
made in any suitable number of lengths segments or parts, and either straight
parallel curved or otherwise, and if necessary any suitable number and sizes of
springs may be arranged to be used together instead of one.
Springs made as hereinbefore described will be found very suitable for expanding
contracting or compressing in a circular or other form and .may be used for all
purposos where metallic springs are required.
In order that tho practical carrying out of my said invention may be more fully
understood I have illustrated it on the accompanying sheet of explanatory
drawings, on which Figure 1, represents and comprises elevations of a portion of a
spring cut or slit straight across at right angles to its sides or edges-a, a, aro
sections of the spring-b, is an edge view of the spring on a straight line. c, is an
edge view of the spring dished transvorscly.
Figure 2, is an elevation of a portion of a spring cut or slit in an angular or
slanting direction.
Figures 3, and 4, are elevations of portions of springs in which the cuts or slits
are wider at the bottom than at the top. d, is an end view of the spring dished
lengthwise.
Figure 5, is an elevation of a portion of a spring with the cuts or slits made
circular at the bottom or end.
Figure 6, is an elevation of a portion of a spring with parts of the edges cut
away, showing some parts of the spring standing higher than the rest.
Figure 7, is an elevation of a portion of a spring with the edges forming an
uneven, or a curved, or an undulating line.
"
Figure 8, represents elevations of portions of springs cut or slit on both edges
and aides. c, and f, are sections of the same.
Figures 9 to 18, are some examples of sections or end views of cut springs.
Figure 19, shows an elevation and a plan of a spring in a circular form.
Figure 20, shows an elevation and plan of a spring also in a circular form but
dished transversely,

page_text: I would here observe that the Figures on the drawings show only some
examples or modifications of my improved cut springs, but other variations or
modifications can as readily be made therein and will answer the same purpose
equally well.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it to be
understood that I do not limit myself to the precise details of the improvements in
metallic springs as herein before described and as illustrated on the accompanying
sheet of drawings because numerous modifications or variations can be made therein
without deviating or departing from the principles or main features of my
invention, and I also wish it to be understood that the precise forms or shapes of
the springs the section of the same or the material from which they are made are
not material to this invention; and in conclusion I declare that what I claim is
The production or construction of an improved cut metallic spring made from
a rod bar or plate of any suitable metallic material and of any desired form or
section, cut or slit transversely at certain, or at varying distances, and the appli-
cation and use of such improved spring for all purposes wherein a durable and
elastic spring is required having a readily expanding contracting or compressing
power.
