IN SHUTTLES
Year: 1878

page_text: PROVISIONAL SPECIFICATION left by the said James Edward Wadsworth
at the Office of the Commissioners of Patents on the 1st June 1878.
JAMES EDWARD WADSWORTH, of Leeds, in the County of York.
'IN SHUTTLES."
"
"IMPROVEMENTS
My improvements consist in so constructing the spindle in the shuttle on which
the bobbins or cops" are placed for weaving purposes that they may be more
easily put on or taken off, also when the spindle is in its working position the
bobbin or "cop" is fast in its place. The act of raising the spindle to an upright
or vertical position releases the bobbin or "cop" which can then be easily removed.
In order to effect this end I so construct the spindle that it can be expanded or
opened outwards by the action of closing it into its working position, and by the
same means the "cop" or bobbin is held firm in its position for working.
The spindle may consist of two or more parts, which being acted upon by a
spring, incline, cam, or their equivalents, expands or moves outwards the parts
during the closing operation, and brings or allows them to come together again by
the act of raising the spindle into an upright or vertical position.
The spindles or pins of ordinary construction are so formed that they damage the
hole through the bobbin or "cop," and render them useless for work; also it is
generally a difficult task to remove the "cops or bobbing, or to place them on the
spindles or pins. By my improvements all these objections are obviated.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Edward Wadsworth in the Great Seal Patent Office on the 27th
November 1878.
JAMES EDWARD WADSWORTH, of Leeds, in the County of York.
IN SHUTTLES."

"IMPROVEMENTS
My improvements consist in so constructing the spindle in the shuttle on which
the bobbin or "cops" are placed for weaving purposes that they may be more
easily put on or taken off, also when the spindle is in its working position the
bobbin or 'cop" is fast in its place. The act of raising the spindle to an upright
or vertical position releases the bobbin or "cop" which can then be easily removed.
In order to effect this end I so construct the spindle that it can be expanded or
opened outwards by the action of closing it into its working position, and by the
same means the "cop" or bobbin is held firm in its position for working.
The spindle may consist of two or more parts, which being acted upon by a
spring, incline, cam, or their equivalents, expands or moves outwards the parts
during the closing operation, and brings or allows them to come together again by
the act of raising the spindle into an upright or vertical position.
The spindles or pins of ordinary construction are so formed that they damage the
hole through the bobbin or "cop" and render them useless for work; also it is
generally a difficult task to remove the "cops" or bobbins or to place them on the
spindles or pins. By my improvements all these objections are obviated.
And in order that my Invention may be more completely understood, reference
is given to the accompanying Drawings and to the letters and marks thereon.
Figures 1 and 2 are longitudinal sections, and Figure 3 a plan shewing the
application of my Invention in various positions in the shuttle.
The shuttle peg or spindle is by preference made in two parts a and b, of half
round steel, and jointed at c in the manner of a pair of scissors. The points of the
pieces a and b are cut out in the manner shewn at d, so as to form a head to resist
the drag on the bobbin or "cop" e. The part a is constructed in one piece with
the hinged block a', which turns when the peg or spindle is lifted on the pin f.
The spring g controls the scissors-like movement of the peg or spindle, and retains
it in the position shewn at Figure 1 when depressed into the shuttle.
The other half or part 6 of the peg or spindle at its hinder portion b¹ passes into
the hinged block a', and projects slightly when the peg or spindle is raised, as shown
at h, Figure 2. When the peg or spindle is in the position shown at Figure 2 the
two parts a and b are closed together, and the bobbin e may be easily placed on it
or removed; but when the peg or spindle is depressed into the shuttle, as shewn at
Figure 1, the projection h comes in contact with the spring g and is forced upwards,
the hinder portion 61 at the same time rises through the hinged block, moving on
the joint pin c, opens the two projecting parts d over the front of the bobbin or
cop e, thus making it impossible for the bobbin or "cop "e to move or slip until the
peg or spindle is again raised into the positions shewn at Figure 2. The pin J is
used as a support for the peg or spindle when in position shewn at Figure 1; the
pink by its action, the inclined surface at 6¹ on the spindle or peg being raised into
the position shewn at Figure 2, closes the parts a and b together for the purpose of
removing the bobbin or "cop."
Having now described the nature of the said Invention, and shewn by Drawings
how the same may be carried into practice, I would have it understood that I do
not limit myself to the precise limits, details, or configuration of the parts I have
expressed and shewn, as the same may be varied or modified, as, for instance,
instead of the spring 9, in some cases an incline, cam, or other equivalent means
may be employed, also modifications in the construction of the peg or spindle, all
without departing from the nature or principle of my Invention; but what I claim
and desire to be secured to me by Letters Patent is, the arrangement, construction,

page_text: and application of expanding and contracting peg or spindle and parts connected
therewith, and any mere modifications of the same, operating substantially as and
for purposes herein set forth.
In witness whereof, I, the said James Edward Wadsworth, have hereunto
set my hand and seal, this Twenty-third day of November, in the year of
our Lord One thousand eight hundred and seventy-eight.
