page_text: Southampton Buildings, in the County of Middlesex, 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:-
This invention relates to that class of loom shuttles which are provided with
means for securing the cop or bobbin on the spindle, when the spindle is closed,.
and consists in a novel construction and arrangement of the parts as hereinafter
set forth the object being to provide a simpler, cheaper and more effective device
of this character than is now in ordinary use.
In the accompanying drawings,
Figure 1 is a vertical longitudinal section of my improved shuttle, the spindle
being represented as closed, expended and locked.
Figure 2 is a like view, the spindle being represented as opened, collapsed and
locked, and
Figures 3 and 4 are views representing a modification of the improvement.
In each of said views a portion of the body of the shuttle is represented as
broken off.
Like letters of reference indicate corresponding parts in the different Figures of
the drawings.
The nature and operation of the improvement will be readily understood by all
conversant with such matters from the following explanation, its extreme simplicity
rendering an elaborate description unnecessary.
A represents the body of the shuttle, B the spindle and C the roller spring.
The spindle is pivotted at t in the body A, and provided on its upper side with
the spring D, the outer end of said spring being welded to the spindle to form the
point 2, and the inner end fitted to work in a socket v, in the shank f.
A hole z, less in diameter than the socket v, extends from the bottom of said
socket through the end of the shank f; and fitted to work in said hole there is a
push-pin, m, provided with a head i, to prevent its escape from the hole, said head
bearing upon the end of the spring D.
An anti-friction roller E, is journalled in the outer or free end of the spring C,
said spring being curved upwardly, provided with a slot r, and adjustably attached
to the body of the shuttle by the screw, h.
The rear end of the shank f, of the spindle B, is cut out or concaved as shown
at b, to receive the roller E, when the spindle is closed.
A stop or projection a, is formed in the body of the shuttle on which the
sbank f, rests when the spindle is closed, a shoulder g, serving to stop the spindle
when it is opened.

page_text: In the use of my improvement, as illustrated in Figures 1 and 2 of the drawings,
the spindle is opened as shown in Figure 2 to receive the cop or bobbin, thereby
causing the roller E, to pass out of or be removed from the cavity b, in the
shank, and permitting the spring D, to straighten out and force the pin m,
outwardly through the hole z, until its head i, rests on the bottom of the socket v.
When the spring D, straightens out as described, its body d, approaches the
spindle proper B, or the spindle considered as a whole, collapses, thereby enabling
it to be inserted in the cop or bobbin.
After the cop or bobbin has been placed on the spindle and properly adjusted
the spindle is closed or brought into parallelism with the body A, thereby causing
the roller E, to roll into the cavity b, in the end of the shank f, forcing the push
pin m, against the end of the spring D, in the socket v, bending or bowing said
spring and securing the cop or bobbin on the spindle in a manner which will be
readily obvious without a more explicit description.
It will also be obvious that when the spindle is closed as described it will be
locked in position by the roller E, and spring C, the roller being forced into the
cavity b, in the end of the shank f, by said spring; also that when it is opened it
will be locked by the spring C, and roller E, the end of the shank f, resting on said
roller or on the spring C near said roller as shown in Figure 2.
The spring C, being constructed with the slot r, may be adjusted on the screw h,
to exert any desired degree of pressure on the spindle B.
In the modification shown in Figures 3 and 4 A represents the body of the
shuttle, B. the main portion or body of the spindle, D the spring of the spindle,
E the roller, C the roller spring, and H the shank or extension of the spring D.
The spindle B, is pivotted at t in the body A, and provided on the upper side
near its point x, with an elongated groove, 12, the bottom of said groove being
inclined or curved upwardly at its forward end as shown at 13.
The spring D, is flattened at its point, as shown at 14, the flattened portion
being curved downwardly at the forward end on its inner or lower edge to
correspond with the curve 13, and fitted to slide in the groove 12.
A socket v, is formed in the shank f, of the main spindle, and extending from
the bottom of said socket outwardly through the end of the said shank there is a
hole z, in the spring D, being elongated or extended as shown at H, and fitted to
work in said hole..
Attached to the inner end of the spring D, and standing at a right angle thereto
is an L-shaped head 15, the arm 16, of which projects forward in the direction of
the spindle over the upper side of the shank f, in parallelism with the extension H,
of the spring D, and at a right angle to the main portion of the head.
The main portion of the head 15, and its arm 16, are rounded or curved at the
corner or angle 17, where they unite to enable them to pass readily over the..
roller.E, as the spindle is opened and closed.
The spring C, is curved upwardly and provided with a slot r, through which
the attaching screw h, passes, the roller, E, being journalled in its outer or
free end.
The flattened end 14, of the spring D, is provided with a diagonally arranged-
slot 18, and is kept in the slot or groove 12, by a pin ; which passes transversely
through the spindle B, and the slot 18, the inclination of the last named slot, to
the longitudinal axial line of the spindle B, corresponding with the inclination of
the bottom of the groove 12, at its forward end 13.
A projection a formed in the body of the shuttle acts as a stop for said spindle
when it is closed, the shoulder g, serving as a stop when it is opened; but any
other suitable means may be employed for stopping the spindle if preferred.
In the use of my improvement, as illustrated in figures 3 and 4 of the drawings,
the spindle being opened and collapsed, as shown in figure 4, if a cop or bobbin is
placed on the same and the spindle closed, the arm 16, and head 15, will be
brought into forcible contact with the roller E and as the rounded corner 17,
passes said roller the spring D, will be forced forward, causing its flattened end 14,

page_text: to ride up the incline 13, until its forward movement is stopped by the end of the
slot 18, bringing up against the pin j, after which it will be bent outwardly as
shown at d, thereby expanding the spindle, considered as a whole, and securing the
cop or bobbin. thereon in a manner which will be readily obvious without a more
explicit description.
As the pivot t, is disposed below the longitudinal axial line of extension H, and
the roller E, so arranged that when the spindle is closed said roller will press on
the head 15 nearly opposite said extension, it will be obvious that the spring C,
and roller E, will act to lock the spindle when closed, or to prevent it from being
accidentally opened as shown in figure 3.
It will also be obvious that when the spindle is opened the curved or rounded
corner 17, will ride down over the roller, E, and pass below its axial line thereby
enabling the spring C, and said roller to lock the spindle in that position, as shown
in figure 4.
The object of the incline 13, is to expand the spindle laterally at or near its
point, the point of the spring as it is pushed forward riding up this incline until
stopped by the pin, j as above described and producing that result.
"
The object of the socket v, is to prevent the portion, 19, of the spring D, from
cramping or binding where it enters the shank f, when pressure is exerted
upon it by the spring C, and roller E. The socket may, however, be dispensed
with by changing the form of said spring D, somewhat where it enters the shank f.
The extension H is fitted to slide longitudinally in a hole z, in the shank f, but
any suitable ways or guides may be provided for said extension at the shank of
the spindle.
It will be understood that the spring D, is sufficiently flexible to bend readily
when pushed forward as described; also that the slot , and screw h, enable the
spring C, and roller E, to be adjusted with respect to the spindle the same as
described in respect to the shuttle shown in Figures 1 and 2.
I do not confine myself to connecting the spring D, and spindle B, at their
forward ends, as shown in Figures 3 and 4, when the spring D, is fitted to work
in a hole or ways at the pivotted end of the spindle and provided with the head 15,
as they may be connected by welding their points together, as shown in Figures 1
and 2, which I deem preferable to the method of connecting them shown in
Figures 3 and 4. I also deem it preferable to construct the shuttle in all other
respects as shown in Figures 1 and 2; but if preferred the pin m may be dispensed
with and the spring D, elongated and provided with the head 15, as shown in
Figures 3 and 4.
