page_text: Improvement in Means of Securing Spindles in Shuttles.
We, THOMAS SUTCLIFFE, Overlooker of Weaving, of Pawtucket, in the State of
Rhode Island, one of the United States of America, and JOHN MARSHALL, Over-
looker of Weaving, of Pawtucket, in the State of Rhode Island, one of the United
States of America, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—-
Said invention relates to an improved means for securing the spindle in the
shuttle frame and at the same time permitting the spindle to be easily and quickly
removed from the shuttle. It consists of slotted grooves made in the end of the
spindle and fitted upon certain provided pins or spindle rests, in combination with
a peculiarly shaped swinging lever, perforated lengthwise to allow the spindle to be
run through it, and governed by a flattened spring as shown.
In the accompany drawing Figure 1, is a longitudinal sectional elevation of a
shuttle having said improved means for holding the spindle; said spindle being
shown in the center of the shuttle and carrying a bobbin.
Figure 2, is a like view of the device, the lever and spindle being swung upward
for the removal of the bobbin.
Figure 3, is a detached view of the exterior of said swinging lever.
Figure 4, is a view of the spindle and bobbin removed from the shuttle, and
showing the deepened grooves for interlocking the spindle with the pins in the
shuttle frame.
a a show the shuttle frame, b the bobbin, c the spindle, d d shoulders on the
spindle having the deepened grooves ef therein; h is the peculiarly shaped lever,
longitudinally perforated as seen at i to receive the slotted end of the spindle as
seen in Fig. 1; k shows a fulcrum for said lever, and m a strengthening arm;
no respectively show fitted pins or rests for the spindle when locked in the shuttle
as hereinafter described; r is a flattened spring, held by the screw 8, and bearing
upon and keeping in place the lever k as seen at t; v is a mid-shoulder on the
exterior of the spindle to steady the bobbin, and to enable the thread to be
unwound therefrom when the bobbin end may be splintered or broken; w shows
a button at the end of the spindle forming an additional stay to the bobbin; e¹ is
the groove in the lever registering with the groovee of the spindle, and y is a
recess in the will of the shuttle frame forming a rest for the arm m of the lever.

page_text: The mutual relation and the combined use of these several parts will readily
appear from the drawing. The end sought is to keep the spindle and bobbin firmly
in their places, and yet to be easily removable, and to greatly prolong the time
within which they may be used without repairing.
The spindle is taken from the shuttle by turning the lever h up into the position
shown in Fig. 2, when the spindle will easily slide out from said lever; the bobbin
is removed from or placed on the spindle while the latter is so separated from the
lever. To replace the spindle, the perforated end is inserted in the central
perforation of said lever, and pressed inward until the shoulder d reaches a
similar shoulder inside said lever and seen at a in Figs. 1 and 3. When the lever
is swung back into place the spindle and bobbin will lie in the center of the shuttle
as in Fig. 1, the slotted groove will interlock with the pin or spindle rest o, and
the slotted groove with the pin n; the spring s will prevent any unlocking of
these parts until the lever his again lifted. When the parts aforesaid are inter-
locked as described and shown, great firmness and steadiness of the spindle and
bobbin are secured, and the operation of the spring r and arm m contribute to
prevent much of the wavering and wearing of the spindle and bobbin which have
been incident to their use heretofore.
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 :-
8
The combination, with a shuttle frame provided with spindle rests no and
having a receding wall y, of a longitudinally perforated lever hinged in one end of
said frame, and having a transom groove e¹ in its under side and also having
laterally extending arm m for engagement with wall y when the lever is down,
a spring for holding the lever down, and a bobbin spindle one end of which is
adapted to be passed through the lever, and in which is formed transverse
grooves fe, one of said grooves engaging with the under side of rest n and the
other groove registering with groove e¹ in the lever and engaging with the top of
rest o, substantially as described.
