WILLIAM A. TEBO, OF ANTHONY, RHODE ISLAND.
SHUTTLE.
Appiication mea January 18,1924. serial No. 686,988.
T all 'whom t may concern,
Be it known that I, WILLIAM A. TEBO, a citizen of the United States, residing at Anthony, in the county of Kent vand State of Rhode Island, have invented certain new and useful Improvements in Shuttles, of which the following is a specification.
This invention relates to an improvement in' the construction of yarn package tensioning and anti-ballooning device more particularly adapted to be applied to loom hutt-les; and the object of this invention is to provide simple and effective means for applying a flexible tension to the coneshaped traverse wind of a yarn package in a shuttle. v
A further object of this inventionV is the provision of a flexible member suspended from the-shuttle in the package opening to engage and apply tension to the unwinding surface of the package when the package is in,v operative posit-ion in the shuttle for the purpose of tensioning and also to prevent excessive ballooning of the yarn as drawn from the package.
A further object of the invention is to so position the flexible tensioning member or members in the shuttle opening as to gradually decrease its Atension on the winding y portion of the yarn as the amount diminishes on the 'spindle owing to the fact that less tension is required, the turns of the unwinding action vof the yarn about the spindle serving in a measure to produce a portion of the required tension.
With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, andvparticularly pointed out in the appended claims.
In the accompanying drawings,
Figure l is a view of the shuttle partly in section looking from the under side thereof and showing the tensioning device as applied to the yarn package.
Figure 2 is a side elevation showing the shuttle broken away and partly in section to better show the yarn package and illustrate the action of the tensioning device as applied to the package.
K igure 3 is a side elevation illustrating a portion of the shuttle in section and showing a binding post as adapted to be rotated for the purpose of tensioning the flexible memt e yarn package.
ber adapted toengage Figure 4c' is a view showing a fragmental portion of the shuttle broken away and illustrating screw means for adjusting the operating length of the yarn-tensioning member, also showing a spring or elastic member as connected to the tensioning member. l
Figure 5. is an enlarged fragmental ysectional view of the yarn package showing the tension cord or member as engaging the inclined or traverse portion of the yarn package.
Figure 6 is a fragmental sectional portion of the shuttle showing one means for fas- 1toening one end of the tension cord or mem- Figure 7 is a view showing a split shot which is adapted to be compressed upon the end of a tension cord, as illustrated in Figure 6, to fasten the end thereof to the body of the shuttle. i
Figures 8, 9 and l0 are plan views of the shuttle illustrating different forms or a-.r-
rangements of tensioning cords or members in the yarn package opening in the shuttle, Figure 11 shows a side elevation partly in section of a shuttle showing the partially empty yarn spindle with the cord tensioning device practically out of contact with the arn.
It is found in the practical operation of shuttles when yarn is being rapidly drawn from the package in the shuttle that it has a tendency'to balloon excessively especially at the ends of a shuttle travel where it comes in contact with the picker check, and
to obviate this diliiculty in such shuttles, I have ,provided simple and effect-ive means for oering a resistance to the too ready pulling off of the yarn from the package at the point where it leaves the package instead of in the eye of the shuttle and as is usual, and which resistance serves to preventV this excessive ballooning of the yarn. l have also so constructed this tensioning device that it will engage the cone-shaped or traverse portion of the package and will automatically follow back this cone-shaped portion as it recedes as the yarn is drawn from the package; and the following is a detailed descriptionof one means by which these advantageous results may be accomplishedt- With reference to the drawings, 10 designates a shuttle which is provided with the usual recess or opening l1 for the yarn package 12 which. is mounted therein in the usual Way, The package as is herein shown is usually Wound With a cone-shaped or traverse portion as at 13 from which the yarn is drawn as the shuttle is dr' ven back and forth across the lay in performing its Weaving function.
ln order to provide simple and eective means for applyingtension to the 5 rn drawn Jfrom the package to prevent excessive ballooning of the yarn as is usually the case in operation, l have provided a flexible member i4: which may be or any suitable material such as a cord9 cat gut, elastic braid, a spring, or any other suitable material which is suiliciently flexible to lie against the yarn 'package and take the form ot the cone-shaped or 'traverse portion for the purpose oliyieldingly engaging the surface ofthis portion of the package. to apply a suitable tension to the yarn as drawn therefrom.
ln some cases9 l obtain this frictionin or tensioning eiiect by providing pair or these tensioning members such as illustrated in Figure l9 and attach the opposite ends l5 and 16 of these members near opposite ends of the package opening in the shuttle andpreferably at points above the axial line of the package, when in normal operating position so that they will lie diagonally in this opening and cross each other as at 17, thecrossing point being determined to some extent by the shape ol' the yarn package so that when this package is swung down into position as illustrated in Figures l and 2, the body of the full package upon engaging these flexible members Will cause the crossing point to come somewhere along the coneshaped or traverse portion of the package the flexibility of these tension members due to the particular position of their end fastenings in the Walls of the shuttle7 being such as to cause this crossing point to folloiv back onrthe cone-shaped or traverse portion as this cone shape moves back as the drawn therefrom thereby provide suitable or desired tension on the yarn as it is being drawn trom the package to prevent ballooning of the yarn at this point.
ln fastening the ends of these flexible crossed members, when a cord and the like is used a knot be tied in its end and drawn into a recess 18 vtermed in the outer face of the shuttle or a split shot 19 or member ot any suitable material may be clamped on to the end of the cord Which may be drawn into the recess 18 in the side of the shuttle to serve as an anchor for the ends of the cord in the shuttle Wall.
l do not Wish to be limited to the position of either the forward end l5 or the rear end 16 ol" this cord or member as secured to the Wall as in some cases the ends may be secured. on a line considerably above the axial line ot' the package as at 20 in Figure ll, or in other cases one end may be secured above this axial line and the other end below this line, as in Figure 2, and in still other casesa as in Figure 8, one cord may be looped over the other cord as at 2L and as illustrated in Figure l0 a Y arrange t as at 22 in Figure l0 may be ern Jed as a friction for the yarnj While in still other cases the cords 23 need not en lend the full length of the opening in the s iuttle as shown in Figure 9.
ln order to adjust the length of these friction members, l have provided a post 24, as shown in Figure around which this member may be Wound, the post being adapted to be rotated in its socket to Wind the cord about it to obtain just the tension required. ln other cases a screw 25 may be inserted through the Wall of the shuttle to Vthe end of which the oord is secured for adjusting' the tension of the same, and in orner to provide greater elasticity to the oord in some cases I may interpose a spring 26 into the cord as illustrated in Figure e, or any other suitable means may be employed for adjusting the operating length of these friction cords or members to apply the required tension on the yarn as drawn from the package. f
My improvedfrictioning device for yarn package isr extremely simple and practical in construction and effective in its operation and by its use the yarn may be drawn from the package in a tlying shuttle Withouterrcessive ballooning.
The :foregoing description is directed solely towards the construction illustrated, but l desire it to be understood that l reserve the privilege of resorting to all the mechanical changes to Which the device is susceptible7 tie invention being defined and limited only by the terms of the appended claims.
l claim:
l, ln a shuttle having a yarnpackage with a cone-shaped traverse Wind, a tension lmember diagonally disposed to extend across the axis of the package having anV elastic body portion to flexibly followthe contour oic the traverse portion of the package to apply a yieldin tension to the yarn as .raivn therefrom.
2. ln a shuttle having a yarn package with a cone-shaped traverse Winda a tension member diagonally disposed to extend across the axis of the package having an elastic body portion withv a soft engaging covering to closely and flexibly follow the contour of the traverse portion of the package to apply a yielding tension to the yarn as drawn therefrom.
3. A. shuttle having an opening to receive a yarn package, a flexible member elastic throughout its length suspended in the 5, In a shuttle having an opening adapted to receive a yarn package with a cone-shaped traverse Wind, a pair of flexible diagonally- 15 disposed members crossed intermediate their ends in the package opening to engage and apply a tension to the yarn as drawn from the package, the Crossing point of' said.
members being arranged to lie against said 20 traverse portion of the package during the rst portion of the unvvinding operation.
