We, JOEL CADBURY of Great Hampton Street, Birmingham, in the County of
Warwick, Manufacturer, and JOSEPH GEORGE ROLLASON of Spencer Street,
Birmingham, aforesaid, Tool Maker, do hereby declare the nature of said invention
for " IMPROVEMENTS IN YIELDING TAB CONNECTIONS FOR BRACES, SUSPENDERS
AND FOR OTHER LIKE ARTICLES," to be as follows:-
Our invention has reference to yielding brace connections consisting essentially
of a coiled spring compressed by a single slide which carries the tabs of the brace;
and our said invention is an improvement upon Letters Patent for an invention
granted to us on the 19th day of August 1884, and numbered 11,418.
The object of our invention is to give increased flexibility, ease and freedom to
yielding brace connections of the kind herein before described, by making the tabs
and their slides moves and act or react upon the spring or springs independently of
each other; that is, the tabs and their slides or connections have independent
motions instead of connecting as heretofore, two tabs to one slide.
The brace connection consists of a buckle frame with a depending semicircular
ended loop which forms the guide bar around which a coiled spring encircles. The
guide bar upon which the yielding spring encircles, in other words consists of a
hanging semicircular loop of wire with parallel sides, with its terminal ends
connected to the lower bar of a buckle or other frame to which the webbing or
brace material is attached, and working and sliding upon each of the parallel guide
bars, and above the terminal or free ends of the spring, are independent elides
carrying brace tabs. These slides press upon the ends of the spring and act
independently of each other; thus the downward movement of one slide upon its
bar, compresses that side of the spring only, while the other tab remains quiescent,
unless pressure be exerted upon it at the same time. The eyes or holes of the
slides are made somewhat larger than the rods upon which they work, so as to
permit of that lateral motion which is requisite for allowing perfect freedom of
motion on the change of posture of the wearer. The independent motion of each.
tab produces independent action and reaction of the spring, and that in consequence
of the lateral play given to the slides, the tabs are capable of widening out and

page_text: giving that freedom of motion which is unattainable where the tabs are combined
or move together.
The slides may be made in the form of a loop produced by folding a strip
of metal upon itself, and connecting its ends to a tab by a rivet or eyelet. The
connection of the tab to the slide may if necessary be in the form of a joint to give
the tab motion independent of the slide. The slide covers and partly conceals the
side bars and spring.
The application of our invention to rectangular or other forms of yielding brace
connections, differs in no essential respect from the kind already described.

Improvements in Yielding Tab Connections for Braces,
Suspenders, and for other like Articles.
We, JOEL CADBURY of Great Hampton Street Birmingham in the County of
Warwick Manufacturer and JOSEPH GEORGE ROLLASON of Spencer Street
Birmingham, aforesaid, Tool Maker, do hereby declare the nature of said invention
for "IMPROVEMENTS IN YIELDING TAB CONNECTIONS FOR BRACES, SUSPENDERS
AND FOR OTHER LIKE ARTICLES," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
Our invention has reference to yielding brace connections consisting essentially
of a coiled spring compressed by a single slide which carries the tabs of the brace;
and our said invention is an improvement upon Letters Patent for an invention
granted to us on the 19th day of August 1884, and numbered 11,418.
The object of our invention is to give increased flexibility, ease and freedom to
yielding brace connections of the kind herein before described, by making the tabs
and their slides move and act or react upon the spring or springs independently of
each other; that is, the tabs and their slides or connections have independent
motions, instead of connecting as heretofore, two tabs to one slide.
་
The brace connection consists of a buckle frame with a depending semicircular
ended loop, which forms the guide bar around which a coiled spring encircles.
The guide bar upon which the yielding spring encircles in other words consists of
a hanging semicircular loop of wire with parallel sides, with its terminal ends
connected to the lower bar of a buckle or other frame to which the webbing or
brace material is attached; and working and sliding upon each of the parallel
guide bars, and above the terminal or free ends of the spring, are independent

page_text: slides carrying brace tabs. These slides press upon the ends of the spring and act
independently of each other; thus the downward movement of one slide upon its
bar, compresses that side of the spring only, while the other tab remains quiescent
unless pressure be exerted upon it at the same time. The eyes or holes of the
slides are made somewhat larger than the rods upon which they work, so as to
permit of that lateral motion which is requisite for allowing perfect freedom of
motion on the change of posture of the wearer. The independent motion of each
tab produces independent action and reaction of the spring, and that in consequence
of the lateral play given to the slides, the tabs are capable of widening out and
giving that freedom of motion which is unattainable where the tabs are combined
or move together.
The slides may be made in the form of a loop produced by folding a strip of
metal upon itself, and connecting its ends to a tab by a rivet or eyelet. The
connection of the tab to the slide may if necessary be in the form of a joint to give
the tab motion independent of the slide. The slide covers and partly conceals the
side bars and spring.
The application of our invention to rectangular or other forms of yielding brace
connections, differs in no essential respect from the kind already described.
We will now proceed to describe with reference to the accompanying Drawings,
the manner in which the same is to be performed.
Figure 1 is a front elevation, and figure 2 is a side elevation of a yielding brace
connection constructed according to our invention. Figures 3 and 4 show the same
with one of the independent slides or tab connections pulled down, and the coiled
spring surrounding the circular ended bar compressed, the top portion of the said
pulled down slide is shown in section in order to exhibit the hole through which
the bar or frame passes; and also the metal at the fold part surrounding the hole,
against which one end of the spring abuts. Figure 5 is the pierced blank of one of
the slides before being bent or folded, about its middle into a U form; and figure 6
is an edge view of the said blank.
The same letters of reference indicate corresponding parts in the several figures
of the Drawing.
b is a depending semi-circular ended loop, which forms the guide bar or bars
around which a coiled spring a encircles. The said bar b is connected at its upper
ends 62, to the brace webbing loop c (or the loop may be substituted by a buckle).
This loop c constitutes the means by which the brace webbing is attached to the
yielding connection-d, d, are two independent slides carrying pullies e, e, at
their lower extremities; and around theso pullies, the cord or connections of the
tabs pass.
These independent tab slides & d are provided at their upper ends with holes dª
through which the bars of the frame b work, and also with abutments or
shoulders d³, against which the ends of the spring abut or press themselves. So
that these slides press or are pressed upon by the ends of the spring, and act
independently of each other; thus the downward movement of one slide upon its
bar, compresses that side of the spring only, while the other tab slide remains
quiescent, unless pressure be exerted upon it at the same time. The eyes or holes
of the slides are inade somewhat larger than the rods upon which they work, so as
to permit of that lateral motion which is requisite for allowing perfect freedom of
motion, on the change of posture of the wearer. The independent motion of each
tab slide produces independent action and reaction of the spring, and that in
consequence of the lateral play allowed to the slides, the tabs are capable of
widening out, and giving that freedom of motion which is unattainable, where the
slides are combined in one, and move together.
Although we have shown that the two independent tab slides act, or are acted
upon by the ends of a single spring, yet two independent springs may be
substituted therefor; in this case the frame is then preferably made rectangular
in form.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
Making that portion of yielding or spring brace connections called the slide, in
two separate parts, so as to admit of independent action and reaction; that is,
providing the tabs, or the connections of the tabs with two slides, instead of one,
which independently act, and are acted upon, by a coiled spring, or by coiled
springs encircling the guide bars, upon which the independent slides move and
work, substantially as described and illustrated.
