Application filed November 10, 1904. Elerial No. 232,109.
To all whom it may concern:
Be it known that we, Gnonen W. Kuieirr and Pn'rnn E. MoCULLoUen, citizens of the United States, residing at lilo iedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Bob- 'bin-Ulutching Means for Rotatable Spindles, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
This invention has for its object the production of a novel centrifugally-acting bobbinclutching means for spinning and other rota table spindles, whereby a yarn-carrier or bobbin is held securely in place upon and rotati'id with the spindle by or through the operation of centrifugal force.
in our present invention a plurality of centrifugally-acting clutching members are arranged synnnetrically about the spindle and connected therewith at their lower ends only, the upper ends of said members being free to move outwardly a limited distance, governed by means acting upon the members at their lower ends.
The construction is simple, cheap to manufacture, and tl'ioroughly efficient, the various novel features contained in our invention being fully described in the subjoined specification and particularly pointed out in the following claims.
Figure 1 is a side elevation of a rotatable spindle having bobbin-clutching means em bodying one form of our invention, a portion of a bobbin being shown in section in proper position on the spindle. Fig. 2 is a similar view, but partly in section and with one of the clutch members removed. Fig. 3 is an enlarged horizontal section on the line 3, Fig. 2, looking-down, but with the clutching members and the retaining device therefor omitted. Fig. 4.- is a perspective view of a clutch member, showing its outer face. Fig. 5 is an inner face view thereof, and Fig. 6 is an enlarged diametrical sectional detail to show more clearly the construction illustrated in Figs. 1 and 2..
o haveherein shown our invention as applied to a r tatablo spinning-s nndle A, having a whirl W, provided with an upturned sleeve "10, connecting it with the spindle, an elongated collar a surrounding the lower part of the spindle adjacent and projecting above the head wa of the sleeve 11:. The head ve is merely an annular enlargement of the sleeve at its upper end and provided with an upturned annular retaining-[iange w, whereby a circular seat is formed concentric with the spindle and between said flange and the collar a.
As shown in Fig. 3, a series of separators are provided to divide the seat into several symmetrical segments, and these simai'ators are conveniently formed by radial pins 1, driven through the flange m and into the collar (1, three of the separators being herein shown.
One of the clutch members is shown separately in Figs. .1: and 5 and comprises an elongated body 2, segmental in cross action and having an outturned foot 3 at its lower end, the head 4 being curved or convex longitudinally.
By reference to Fig. 5 it will be seen that the inner face of the clutch member reeessod at 5 to receive the spindle and at (J to [it loosely around the collar 1/, and it may be stated that this enlargement may be an integral part of the spindle instead of a collar driven thereon. The feet 2-5 lit loosely in the circular seat in the head wa around thespindle and are held properly separated from each other by the separators l, as will be manifest, the several clutch members loosely embracing the spindle, as in Figs. 1 and 2, and being vertically supported on their feet 5. A retail'iing device now applied to retain the clutch members in position and to limit the radial movement of their upper ends when thrown outward by centrifugal force d no to rotation of the spindle. This retaining device we have shown as a ring or collar 7, adapted to be forced, with a driving it onto the out side of the flange on and adjacent peripheral portion of the head wa and having at its up per end an inturned annular flange 5%, which overhangs the outspread feet 3 of the clutch members.
Referring to Figs. 2 and 6, the operative portion of the retaining device will be clearly seen, a slight clearance being left between the under face of the flange 8 and the upper faces of the feet 3 and between the inner edge of the flange and the bodies of the clutchmembers. These clearance spaces permit the clutch members to tip or rock slightly upon their feet, so that their upper ends or heads can move toward and from the spindle, and when the latter is at rest the clutch members stand substantially upright and close to the spindle, as in Figs. 2 and 6. V hen the spindle rotates, the heads of said members are thrown outward, as in Fig. 1, and firmly engage the walls of the chamber 5 in the bobbin B, causing the latter to be rotated by the spindle, yet permitting the removal or application of the bobbin with perfect ease while the spindle is running at speed. The flange 8 serves also as a bobbin-rest, as will be manifest in Fig. 1, vertically supporting the bobbin at the proper height on the spindle.
Rotation of the clutch members in unison with the spindle is secured by the separators 1. Said clutch members can readily be stamped, struck up, or otherwise shaped from metal of suitable thickness, their externallyconveXed heads guiding the bobbin when applied to the spindle and permitting the mouth of the chamber 6 to contract the heads of the clutch members as the bobbin is pushed down to its seat or rest 8.
Having described our invention, what we claim as new, and desire to secure by Letters Patent, is
1. The combination, with a rotatable spindle, of a plurality of centrifugally-acting bobbin-clutching members mounted upon it and bodily rotatable therewith, and means acting upon the lower ends only of said members to retain them in position and prevent lifting movement thereof while permitting limited radial movement of their free upper ends.
2. The combination, with a rotatable spindle, of a plurality of centrifugally-acting bobbin-clutching members mounted upon it and bodily rotatable therewith, each of said members having an outturned foot at its lower end, and means to cooperate with the feet and retain said members in position while permitting radial movement of their upper ends.
3. The combination, with a rotatable spindle having an attached annular and concentric seat, of a plurality of upright and elongated bobbin-clutching members symmetrically arranged about the spindle and each having a segmental, outturned foot at its lower end resting in the seat, and overhanging means to act upon the feet of said members and retain them seated while permitting them to tip or rock by or through the action of centrifugal force.
4. The combination, with a rotatable spin- I dle, of a plurality of centrifugally-acting bobbin-clutching members mounted thereupon and arranged symmetrically around it, means to separate said members laterally and cause their bodily rotation with the spindle, and means acting upon the lower ends only of said clutching members to loosely confine and retain them in position on the spindle while permitting radial movement of their free upper ends, said means preventing lifting movement of the clutching members.
5. The combination, with a rotatable spindle, having an attached annular bobbin-rest, of a plurality of symmetrically-arranged bobbin-clutching members loosely surrounding the spindle and free at their upper ends, each of said members having at its lower end an outwardly-extended foot projecting beneath the bobbinrest, the latter thereby retaining said members in position and permitting them to tip or rock by centrifugal action.
6. The combination, with a rotatable spindle having an attached annular and concentric seat, separators to divide the seat into equal segmental portions, and an annular bobbinrest overhanging the seat, of a plurality of centrifugally acting bobbin clutching members surrounding the spindle and each having an outturned foot to project loosely beneath the bobbin-rest and enter one of the segmental portions of the seat, the cooperation of the feet and the bobbin-rest confining the clutching members at their lower ends while permitting limited radial movement of their free upper ends.
7. The combination, with a rotatable spindle having a whirl and an attaching-sleeve provided with a head having an upturned, peripheral flange concentric with the spindle, of a plurality of elongated, centrifugally-acting bobbin-clutching members symmetrically arranged around the spindle, each member having an outturned foot resting on the head within its flange, and a collar secured to the head and having an inturned, annular flange overhanging the feet, to retain the clutching members in place and also serving as a bobbin-rest.
8. A centrifugally-actingbobbin-clutching member for rotatable spindles, having an elongated body segmental in cross section, an outturned foot at its lower end, and a head having its external face longitudinally convex, as and for the purpose described.
9. The combination, with a rotatable spindle, of a plurality of centrifugally-acting bobbin-clutching members mounted upon it and bodily rotatable therewith, and means positively cooperating with the lower ends only of said members to prevent upward movement thereof and permit radial rocking movement thereof about their said lower ends.
10. The combination, with a rotatable spindle, of a plurality of centrifugally-acting bobbin-clutching members, bodily rotatable there With, means to vertically support the lower names to this specification in the presence of ends of said members and permit them to rock radially about fulcra at their lower ends, and
means positively cooperating with such lower two subscribing Witnesses.
