IMPROVEMENTS IN LOOM-SHUTTLES
Year: 1883

page_text: LETTERS PATENT to Charles Henry Nichols, of the Oity of Boston, and State
of Massachusetts, in the United States of America, for an Invention of
IMPROVEMENTS IN LOOM-SHUTTLES
COMPLETE SPECIFICATION filed by the said Charles Henry Nichols at the
Office of the Commissioners of Patents on the 24th December 1883.
CHARLES HENRY NICHOLS, of the City of Boston, and State of Massachusetts,
in the United States of America, IMPROVEMENTS IN LOOM-SHUTTLES,
This Invention relates to Improvements in Loom-Shuttles, whereby the threading
of the same may be more easily accomplished, and the unhealthy practice of
weavers in threading the shuttle by applying the lips to the eye of the same and
sucking the thread through the eye from the inside to the outside, may be
avoided.
In carrying out my invention I construct the shuttle with a curved metal plate
secured in position on the upper face of the eye-end of the same, leaving a narrow
space between the curved end of the plate and body of the shuttle, and form a slot
leading from the intervening space down into the eye of the shuttle.
The shuttle thus constructed may be threaded by taking the thread from the
bobbin and passing it around beneath the curved forward end of the metal plate
into the space, and downward through the slot into the eye of the shuttle.
The proper tension on the thread is produced in threading the shuttle by
carrying the thread around a curved tension-post which extends vertically from
the interior opening of the shuttle and is secured at its upper end to the said
curved plate; whereby the desired friction may be produced upon the thread, and
all kinks removed therefrom in the operation of weaving.
But in order that my invention may be more fully understood, I will proceed to
describe the same more in detail, by aid of the accompanying drawings.
Figure 1. Represents a perspective view of a shuttle embodying my invention.
Figure 2. Represents a sectional elevation of a portion of the same.
Figure 3 Represents a top plan of the same with the curved plate removed.

page_text: A represents a shuttle having a spindle B provided with a wound bobbin of
thread C, as usual To the top face of the forward end portion of the said
shuttle A is secured one end of the curved metal plate E, by a screw F passing
through the same and into the body of the shuttle, the opposite end portion of the
said curved plate E being secured in position, so as to leave a narrow space
intervening between it, and the body of the shuttle which is provided with an
eye H, connected with the said space by a vertical slot L passing through the side
portion of the shuttle from the interior opening thereof, so that the thread C of
the bobbin may be passed beneath the forward end portion of the said plate E
into the said space and thence downward through the said slot L into the eye H
of the shuttle; by which movement the said thread C is carried around the
curved vertical tension-post P, the lower end of which is secured within the
opening of the shuttle near the forward end portion of the body of the same, and
the upper end thereof is secured to the curved forward end portion of the said
plate E, whereby that end portion of the plate is held in position, and the upper
end of the post is protected from catching the threads of the warp as the shuttle is
passed between them in the operation of weaving.
Having thus described the nature of my Invention and the manner of
performing the same I would have it understood that I claim: -
.
The combination with the shuttle A provided with a thread-eye H having a
vertical slot L, of the curved plate E, and vertical tension-post P connected
at its upper end to the said plate, substantially as described, and for the
purposes set forth.
In witness whereof I, the said Charles Henry Nichols, have hereunto set my
hand and seal this tenth day of December, in the year of our Lord One thousand
eight hundred and eighty three.
CHARLES HENRY NICHOLS (L.S.)
