Year: 1857

page_text: LETTERS PATENT to Charles Winslow, of the State of Massachusetts, of
the United States of America, for the Invention of " AN IMPROVEMENT IN
THE MANUFACTURE OF ELASTIC GORE CLOTH."
Sealed the 16th February 1858, and dated the 18th December 1857.
COMPLETE SPECIFICATION filed by the said Charles Winslow at the
Office of the Commissioners of Patents, with his Petition and Decla-
ration, on the 18th December 1857, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT KNOWN
that I, Charles Winslow, of the State of Massachusetts, of the United States
of America, have Invented "AN IMPROVEMENT IN THE MANUFACTURE OF ELASTIC
GORE CLOTB," and I do hereby declare that the nature of the said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following Specification and the accompanying
Drawings, of which Figure exhibits a strip of elastic gore cloth having its
edges turned over and arranged with reference to its warp and weft, in
accordance with my Invention.
The elastic fabric on which my Invention is based, is either one made of
common.cloth stretched and united by an elastic cement, or that for which
Letters Patent of the United States of America were granted, on the Sixth
day of May, A.D. 1856, to Henry G. Tyer and Johu Helm. such elastic

page_text: fabric being composed of two pieces of cloth, either woven or otherwise made
with the threads of the weft in a diagonal position, , or at an acute angle to the
threads of the warp, and combined and caused to adhere together by a cement
composed either of india-rubber or gutta percha, the two pieces of cloth being
united by the compound, and the latter being afterwards vulcanized or not, as
circumstances may require.
In carrying out my improvement, 1 take of such fabric a strip, of a width
Somewhat greater than it is to be when finished for being cut into elastic
gores or made into an elastic band or belt, and I turn over and cement
down upon the main part of the strip, and by a suitable rubber cement, or a
like composition, each edge of the material, lapping it upon the main part of
the strip about a quarter of an inch, or such other distance as may desirable,
in order to imitate binding. And, furthermore, previons to the said strip
having its edge or edges so turned down and cemented, each edge to be turned
is to be cut on an acute angle to or out of parallelism with either the filling or
the warp threads. For obtaining the maximum elasticity, the cut may be made
at an acute angle with the filling of the cloth, and also at an acute angle with
the warp threads, in order that when the edge is overlapped and turned down,
the line of bend of it may be at such an acute angle with either the warp or
weft threads as shall be the complements of half the angle which they make
with each other. In the Drawings, the directions of the warp threads are
indicated by the black lines at a, a, while those of the filling are denoted by
red lines, as shown at b, b, A being the strip of cloth having its opposite
parallel edges turned down or overlapped upon the rest of the cloth, as shown
at c, c, and also in Figure 2, which is a transverse section of the fabric. By
thus arranging the overlap with respect to the warp and weft, elasticity is
secured longitudinally in the binding, so as not to counteract the elasticity of
the remainder of the cloth. Furthermore, the edges are prevented from either
fraying out or being torn, they being much strengthened, and a finish is given
to the cloth. I would remark that the strip is inelastic width wise in direction
of either the warp or weft, and clastic only in the direction lengthwise, or not
of parullelism with either warp or weft. (The blue lines, exhibit the
manner in which the strip is to be cut into elastic gores, each gore being
either of a trapezoidal or triangular shape, or an approximation thereto, as
circumstances may require.)
I am aware that au elastic cloth has been made as a shirred fabric. This,
however, differs essentially from the "elastic gore cloth" made in accordance
with my Invention, as the edge of the former is turned over parallel to
the warp.

page_text: I do not claim the peculiar elastic cloth as made with its filling arranged
at an acute angle with its warp, nor do I claim the elastic fabric as
made of two layers of such cloth combined; but what I do claim as an
improved manufacture, is an elastic band or gore cloth when made not only
of a fabric composed of a cement of india-rubber or gutta percha and two
pieces of cloth, in which the warp and weft of each piece are made to cross one
another diagonally, or at acute angles, but with the edges of the cloth cut and
overlapped and cemented down in a line or lines out of parallelism with either
the warp or weft threads, the line of maximum elasticity in the binding
making that angle with the warp as well as the weft, which is the comple-
ment of half the angle which they make with each other.
In testimony whereof I have hereunto set my signature and seal, this
27th day of November 1857.

TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT KNOWN
that I, Charles Winslow, of the State of Massachusetts, of the United States
of America, have Invented "AN IMPROVEMENT IN THE MANUFACTURE OF ELASTIC
GOBE CLOTH," and I do hereby declare that the nature of the said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following Specification and the accompanying
Drawings, of which Figure 1 exhibits a strip of elastic gore cloth having its
edges turned over and arranged with reference to its warp and weft, in
accordance with my Invention.
The elastic fabric on which my Invention is based, is either one made of
common cloth stretched and united by an elastic cement, or that for which
Letters Patent of the United States of America were granted, on the Sixth
day of May, A.D. 1856, to Henry G. Tyer and John Helm, such elastic

having its edge or edges so turned down and cemented, each edge to be turned

at an acute angle with the filling of the cloth, and also at an acute angle with

the line of bend of it may be at such an acute angle with either the warp or

of either the warp or weft, and elastic only in the direction lengthwise, or not
of parallelism with either warp or weft. (The blue lines f,f, exhibit the

either of a trapezoidul or triangular shape, or an approximation thereto, as

with the filling threads
EDB, or ECB. or DBF or CBG. is the angle made
by the binding c with the warp or filling in Order to
insure the maximum of Elasticity on the binding
and gore. This angle is the complement of the
angle EBD, which equals one half of the angle CBD.
