QUILL OR BOBBIN HOLDING DEVICE FOR BOBBIN-WlNDlNG SPINDLES.

SPECIFICATION forming part of Letters Patent No. 416,292, dated December 3, 1889. Applloationfiled October 13, 1888' Serial No. 287,996. (No model.)

To all whom it may concern:

Be it known that I, HENRY CLAY FOWLER, a citizen of the United States, residing at Burlington, in the county of Alamance and State of North Carolina, have invented new and useful Improvements in Quill or Bolobin Holding Devices for Bobbin- W'inding Spindles, of which the following is a specification.

My invention relates to improvements in quill or bobbin holding devices for bobbinwinding spindles, and has for its object the provision of a device by which the pin-holes and slots heretofore employed in the end of the quill will be dispensed with, and the'quills rendered more durableand serviceable This object I accomplish by means of the construction illustrated in the accompanying drawings; and the invention consists in certain novel features of the same, as will be hereinafter first fully described, and then pointed out in the claim.

In the drawings referred to, Figure 1 is an elevation of a bobbin-winding spindle, showing the quill mounted thereon and provided with my improvement. Fig. 2 is a longitudinal section of a portion of the quill and my improved cup or holding device. Fig. 3 is a detailed perspective view of the cup.

Referring to the drawings by letter, Adesignates the spindle, of the usual or any preferred construction, and B designates the quill, also of the ordinary construction. The base or widened end of the quill, however, in my device may be made smooth and without the usual pin-holes or slots.

G designates my improved cup, consisting of a central sleeve ortube D, which is adapted to fit snugly within the bore of the quill, and is provided at its lower end with internal screw-threads E, which are adapted to engage external screw-threads E on the spindle to secure the cup thereto. Near the lower end of the central sleeve D, I provide the outstanding horizontal annular plate F, from the edge of which the spring flange or collar G projects upward the desired distance, as shown. This flange or collar is provided at diametrically-opposite points with the vertical slits H, thereby dividing the collar into the tongues I I, which are adapted to bind around the lower end of the quill and thereby hold the same Within the cup.

In operation the quill or bobbin is secured in position by adjusting it upon the spindle A and sleeve or tube D, and causing the divided flange at the lower end of the cup or holder to pass around the lower end of said quill, which is thereby clamped and retained securely in position.

It will be observed that the divided flange extends up theside of the quill beyond the annular groove therein, so as to prevent the thread, when being wound thereon, passing into the said grooves, so that when the quill is placed in the shuttle the spring which engages the said groove will not catch in the thread and break the same. The breaking of the thread from this cause has been a very objectional feature of the devices heretofore produced. It will furthermore be observed that by my improved device the quill can be placed on the spindle while the spindle is in motion, which was not possible by the devices heretofore employed, as in the prior devices it was necessary to cause the pins and slots to engage before the quill could be applied to the spindle. Consequently by my device a saving of time will be effected and the quills can be wound more rapidily than heretofore. Furthermore, the slots and pin-holes heretofore employed being dispensed with, the quill can be made solidheaded, so that it will be much stronger and consequently more durable.

My device can be applied to any winding or quilling machine, and its advantages are thought to be obvious from the foregoing description taken in connection with the accompanying drawings.

Having thus described my invention, what claim, and desire to secure by Letters Patent, 1s

The herein-described quill or bobbin holding device, comprising a central sleeve or tube interiorly threaded at its lower end and having at its lower end a horizontal annular
