OLIVER G. BURR, OF NORTH ADAMS, MASSACHUSETTS.

BOBBIN-HO LDER AND THREAD-CATCHER FOR SPINDLES.

SPECIFICATION forming part of Letters Patent No. 627,249, dated June 20, 1899. Application filed October 6, 1898. Serial No. 692,789. (No model.)

To all whom it may concern.-

Be it known that I, OLIVER C. BURR, a citizen of the United States, residing at North Adams, in the county of Berkshire and State of Massachusetts, have invented new and use ful Improvements in Bobbin -Holders and Thread-Catchers for Spindles, of which the following is a specification.

This invention appertains to improvements in attachments for spindles, and has in view to provide a bobbin-holder and thread-catcher which is light and simple in construction and which in use will hold the bobbin centered on the spindle by engaging with the bore thereof, which bobbin-holder is so constructed that a part thereof will coiiperate with a threadcatcher, said thread-catcher being mounted on the bobbin-holder and spindle and positioned beneath the bobbin-head, the device being adapted for use withspindles of spinning-machines, mules, or spinning-frames My invention embodies a device which includes abobbin-holderhaving below that portion which is engaged by the bobbin members which cocperate with a movable threadcatcher about which the thread is wound prior to doffing the bobbin, so that when the bobbin is doffed the thread-carrier will be raised and the thread or yarn which is Wound about the same will be brought under the arms which depend from the bobbin-holder, so that the thread or yarn will be grasped between the depending fingers of the bobbin-holder and the spindle, the construction being such that the thread or yarn will be released when the bobbin is pressed home upon the spindle.

The invention consists in the special construction and combination of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings, which illustrate the invention, Figure 1 is a side e1evation, the bobbin being shown in section, as well as the yarn which is wound about the same, and in this view the taller-wire is indicated as lowered, the yarn being in the position which it will occupy prior to doffing. Fig. 2 is a side elevation showing the bobbin raised, the taller-wire in its normal position, and the yarn held by the thread-catcher; and Fig. 3 is a detail perspective view of the bobbin-holder and thread-carrier separated.

The spindle and bobbin B, as well as the faller-wires,'are of the ordinary construction.

The bobbin-holder E is preferably made up of a single piece of resilient metal and co1nprises aband e, theinternal diameter of which is slightly less than the diameter of the spindle at the point where it engages the same. From the band extends aplurality of fingers e, shaped so that their upper ends will converge to engage the spindle, thus providing convex or rounded surfaces for engagement with the bore of the bobbin. These fingers are concavo-convex in cross-section, they bein g bent both longitudinally and transversely. The lower members or claws 6 which are preferably integral with the band 6, spring outward and downward therefrom, the ends being curved outward. In the construction of the bobbin-holder the claws or members 6 are of less width and greater resiliency than the fingers e which project from the opposite side of the band.

The thread-carrier F comprises a ring f, having depending arms or members f, and the ring is of such a diameter that it may be passed over the bobbin-holder and will be retained thereon bythe outwardly-bent ends of the claws or members (2*. The arms or members f are bent so as to form a recess, with an inclined shoulder forming a part thereof, and below the recess the arms extend outward and downward, the terminals being bent inward. The construction is such that the arms f when the parts are assembled will occupy a position between the claws 6 The ring f is of a diameter slightly greater than the diameter of the bore of the bobbin adjacent to the head, so that the bobbin-head will engage therewith when placed on the spindle. In operation the bobbin-holder and thread-carrier are placed upon the spindle, as shown, and the ICO bent portion or recess of said arms. The bobbin is then raised, and the thread which depends therefrom will raise the thread-carrier and cause that portion of the thread which encircles the arms to be placed beneath the claws c of the bobbin holder or member E, and the thread is broken in the operation of doffing. When an empty bobbin is placed on the spindle, the taller-wires are raised to their normal position andthe thread is given one or two turns about the bobbin sufficient to hold it thereon, after which the bobbin is pressed downward, which operation depresses the thread-"carrier and frees the end of the thread, which, being released, is wrapped about the bobbin, thus avoiding loose ends. The device hereinbefore described is extremely light, occupies but little space upon the spindle, and holds the bobbin by internal rather than by external contact. No auxiliary springs are necessary, and the thread when in engagement with the arms of the threadcarrier causes said arms to frictionally engage the spindle, and with this device the thread is positively released without other manual effort than is required to place the bobbin properly upon the spindle.

The device hereinbefore described is susceptible of modification as to construction; but the embodiment shown comprises a practical and cheap form of construction.

' Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a bobbin-holder, a band carried by the spindle and provided with members which are engaged by the bore of the bobbin, and depending thread-grasping members the lower ends of which are bent'outward from the spindle, together with a thread-carrier movably mounted upon the bobbin'holder.

2. In combination with a spindle, a bobbinholder and thread-grasping device consisting of a band which encircles the spindle, bobbinengagingmembers which project from the band said members being curved longitudinally and transversely, and thread-grasping members which diverge from the opposite side of the band.

3. In a bobbin-holder and thread-grasper 1' for spindles, the combination with a spindle, a bobbin-holder and thread-grasper mounted on the spindle and comprising a retainingband with sets of resilient members which project therefrom, one set of the members being adapted to engage the bore of the bobbin when placed on the spindle, the other set of members diverging from the band, of a thread carrier movably mounted on the th read-grasp ingmembers of the device, for the purpose set forth.

4. In combination with a spindle, a threadholder therefor consisting of a band fixedly attached to the spindle and provided with diverging members, of a thread-carrier movably mounted upon said members and adapted when moved thereon to carry the thread beneath the diverging members.

5. In combination with a spindle, a bobbin and thread holder carried by the spindle, of a thread-carrier which is movably mounted on the bobbin and thread holder the same comprising a band which surrounds the holder and has depending members with shoulders, for the purpose set forth.

6. In combination with a spindle, a bobbinholder and a thread-graspin g device mounted upon the spindle, of a thread carrier or guide mounted movably on the thread-grasping device, the parts having interm eshing members between which the thread is grasped when wrapped about the members of the threadcarrier, which carrier is raised by the thread attached to the bobbin in doifin g, and lowered to release the grasped thread when engaged by the bobbin.

7. In a thread-grasper for spindles, the com bination with a spindle, bobbin, and bobbinholder, a thread-grasping means comprising arms which diverge from the spindle the lower ends of said arms being bent outward, of a thread-carrier consisting of a band having thread receiving and guiding arms.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
