JOHN RILEY, Overlooker and ARTHUR ORRELL, Brewer, both of Bradford in the
county of York IMPROVEMENTS IN LOOM SHUTTLES
«
"
Our invention relates to improvements in loom shuttles, whereby the unnecessary
waste of the thread or yarn produced by the percussive blows of the picker staffs
on the shuttle and by the sudden stoppage of the shuttle at the end of its stroke
across the loom is prevented or greatly reduced when weaving from weft in the
cop, spool or tube, as these, in shuttles usually employed, result in a large waste of
thread or yarn, besides loss of time by the weaver in removing such waste from the
shuttle.
For this purpose we construct shuttles with skewers or pikes having a movable
action so as to gradually take up or neutralize the action in such a manner that
when the picker staff strikes the shuttle and forces it across the loom, or on the
sudden stoppage of the shuttle (which in the shuttles usually employed detach the
cop, spool or tube from the skewer or pike or from the spindle and often produce
great waste of thread or yarn and a consequent loss) the lifting or moving of the
cop, spool or tube is prevented and also the removal of the thread or yarn or
layers of thread or yarn which has hitherto resulted in great waste of thread
or yarn.
On the spindle of the shuttle we fit a spiral spring which is held in working
position by a pin passed through the spindle, and on the skewer or pike on which
is placed the cop, spool or tube, we secure on the end a socket which is made to
slide over the spiral spring; at a given distance in the inside of the skewer or
pike, is fitted a stop plate on which butts the top end of the spiral spring; we can
fit the spiral spring on the spindles of shuttles now in use and also secure a socket
on the skewer or pike, and the alterations can be made at a very small cost.

position for weaving and 'the loom put to work, the action of the picker staff
actuating the shuttle causes the skewer or pike having the cop, spool or tube to be

the effect of the concussion, thereby preventing the lifting or moving of the cop,
spool or tube and also the removal of the thread or yarn or layers of thread or
yarn which has hitherto resulted in great waste of thread or yarn

JOHN RILEY Overlooker and ARTHUR ORRELL, Brewer, both of Bradford in the
county of York "IMPROVEMENTS IN LOOM SHUTTLES
"
The said invention relates to improvements in loom shuttles, whereby the
unnecessary waste of the thread or yarn, produced by the percussive blows of the
picker staff's on the shuttle and by the sudden stoppage of the shuttle at the end of
its stroke across the loom is prevented or greatly reduced when weaving from weft
in the cop, spool or tube, as these in shuttles usually employed, result in a large
waste of thread or yarn, besides loss of time by the weaver in removing such
waste from the shuttle.
For this purpose we construct shuttles with skewers or pikes having a moveable
action so as to gradually take up or neutralize the action in such a manner that
when the picker staff strikes the shuttle and forces it across the loom, or on the
sudden stoppage of the shuttle (which in the shuttles usually employed detach the
cop, spool or tube from the skewer or pike or from the spindle and often produce
great waste of thread or yarn and a consequent loss) the lifting or moving of the
cop, spool or tube is prevented and also the removal of the thread or yarn or layers
of thread or yarn which has hitherto resulted in great waste of thread or yarn.
Over the spindle of the shuttle we fit a socket and a spiral spring which are held
in working position by a pin passed through the end of the spindle or by a nut;
the spiral spring butts against the shoulder of the socket and the skewer or pike is
secured to the socket and by preference soldered thereon; the skewer or pike
secured to the socket receives when the picker staff strikes the shuttle to force it
across the loom or on the sudden stoppage of the shuttle a moving action which
prevents the cop, spool or tube becoming detached from the skewer or pike; we
also form on the end or near the end of the skewer a screw to further prevent the
detaching of the cop, spool, or tube; the screw may be made with a wire soldered

page_text: on the skewer or pike or by pressing out the metal of the skewer or pike; the
screw wire may be secured the length or nearly the length of the pike and on pikes
or skewers made of wood or of other suitable material or substance.
We may,
instead of the skewer or pike having a screw, employ skewers or pikes made of
four blades of steel or of any other suitable material; these blades are elastic and
springing and are secured to the socket; also the top end of the spindle works in a
socket soldered to the four blades of steel.
The cop, spool or tube having been placed on the skewer or pike and in position
in the shuttle for weaving and the loom put to work, the action of the picker staff
actuating the shuttle causes the skewer or pike having the cop, spool or tube to
move forward and thus gradually take up and neutralize the effect of the concussion,
thereby the lifting or moving of the cop, spool or tube is prevented and also the
removal of the thread or yarn or layers of thread or yarn which has hitherto
resulted in great waste of thread or yarn; the spiral spring brings the cop, spool or
tube back in position.
We can apply our improvements to any shape or make of loom shuttles.
By these means we prevent waste of material and loss of time of the weaver.
But in order to enable our improvements to be better understood we will proceed
to describe the same by reference to the accompanying drawing in which figure 1,
represents a section of a shuttle fitted with our improvements; figure 2, represents
a side elevation of a shuttle spindle fitted with socket spiral spring and shewing a
section of the skewer or pike; figure 3, represents a section of the spindle, socket
and spiral spring; figure 4, represents a section of skewer or pike with stamped
out serew; figure 5, represents a back view of the socket and figure 6, front view
of the same; figure 7, represents an outside view of shuttle spindle fitted with
socket, spiral spring and steel skewer or pike and figure 8, section of same.
Similar letters of reference are used to represent similar parts.
A, is the shuttle spindle made by preference with a taper end B, over which is
passed a socket C, having a recess D, to fit over the shank end of the spindle; a
spiral spring E, by preference made taper, is fitted over the spindle B, and the
socket and spring are secured in position on the spindle by the nut F, or by a pin
which may be passed through the top end of the spindle; when the socket and
spiral spring have been secured in position the skewer or pike G, is passed over the
spring and on the round part H, of the socket C, and secured to the socket by
solder by preference and the skewer or pike G, is made with a screw which is
either made of wire as at I, figures 1, and 2, or secured the length or nearly the
length of the pike and also on wood or other suitable pikes or skewers; or by
pressing out the metal as at J, figure 4; the wire screw is soldered on the skewer or
pike. Or we construct the skewer or pike with four steel or metal blades M; one
of these blades M³ is made longer to act as a guide on the slide on the shuttle
spindle A; the blades have a kind of spring which prevents the detaching of the
cop, spool or tube from the skewer or pike; the end of the spindle B, works in a
guide O, formed in a socket P, which is secured to the blades M.
The cop K., or spool or tube having been passed onto the skewer or pike by giving
a slight turn to pass over the screwed end and being placed in position in the
shuttle L, as shewn in the drawing and the loom put to work the action of the
picker staff will actuate the shuttle and cause the skewer or pike to move forward
consequently the socket will move on the spindle end B, and compress the spiral
spring E, which gradually takes up and neutralizes the effect of the concussion,
thereby the lifting or moving of the cop, spool or tube is prevented as also is the
removal of the thread or yarn or layers of thread or yarn which has hitherto
resulted in great waste of thread or yarn; the spiral spring E, brings back the
skewer or pike in position.
Having thus described our invention and the best means we are acquainted with
for carrying the same into effect, we would have it understood that we do not
confine ourselves to the precise size and details shewn as they can be varied

page_text: without departing from the peculiar character of the invention, but What we
claim is :-
Firstly. The manufacture and employment of improved loom shuttles fitted with
skewers or pikes having moveable actions, so as to gradually take up or neutralize
the actions of the percussive blows of the picker staffs on the shuttles and of the
sudden stoppage of the shuttles on the end of its stroke across the loom thereby
preventing waste of thread or yarn or of layers of thread or yarn substantially
in the manner and for the purpose herein described and represented in the
accompanying drawing.
Secondly. The construction and employment of skewers or pikes made with
screwed threads or of skewers or pikes made of steel or other metal or wood or of
other suitable material or substance for preventing the lifting of the cops, spools or
tubes from the skewers or pikes substantially as described and represented in the
drawing.
In Witness whereof we the said John Riley and Arthur Orrell have hereto
set our hands and seals this fifth day of March in the year of our Lord
one thousand eight hundred and eighty three
