OF PORTLAND, MAlNE, A UURPOHA SPEGIFICATIQH forming part of Letters Patent No. F86,698, dated April L, 1965.

Application filed January 1 1904:. Serial No. 189,022.

To all 1072,0727, it may con/00772 Be it known that I, SIMON \V. lVAnmvnLL, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode island, have invented new and useful Improvements in Cop-Tubes, of which the following is a specification.

My invention relates to improvements in cop-tubes, or tubes for supporting yarn packages, especially in cases where the yarn must be subsequently removed from the tube by unrolling.

My improved cop-tube is partilcularly intended for use in warp-creels.

Figure 1 is a perspective view of the coptube; Fig. 2, a sectional view showing, in addition to the structure, the manner in which the cop-tube is secured to the winding-machine spindle.

My invention consists-in building the tube of alight shell (1 of paper, fiber, or other suit able material, with protecting end pieces 7) 7), each of which projects within the shell and is formed with an axial bore a and a cupped or concave inner end (Z. The end pieces 71 may be of wood or any firm material and are directly and securely fastened to the shell by cementing or other suitable means. Both end pieces are formed with shoulders a, which abut and protect the ends of the fiber shell, and a mutual protection is afforded the end pieces by providing for the shell to project slightly beyond their peripheries. One of the end pieces is preferably formed with a transverse recess f across the axial bore 0, or both pieces may be so formed.

W hen a yarn package is wound, the tube secured to the winding-spindle in the manner indicated in Fig. 2. The dog or driver 9 {a part of the winding-spindle h) engages the recess f. This engagement is maintained by the spring-catch '27, which prevents longitudinal displacement of the cop-tube on the spindle. The cupped or concave inner ends (Z of the end pieces 7) Z) are to facilitate mounting the cop-tube on both the winding-spindle and the creel-spindle. Acting a funnel, they guide the end of the spindle to the axial bore 0.

Other forms of built-up tubes and spools have been attempted, but none so simple and 5 efiective as that herein described. The manner'o't' securing the ends has been less protect ive, and therefore the cop-tube has been more liable to damage and destruction.

in my improved cop-tube the ends of the 5 shell in are protected by the end pieces 7/ 7), preventing the disintegration of the luminary structure of this part of the tube, and, further, the shell in turn protects the end pieces from damage or destruction. llhrough its projection beyond the periphery of the end pieces the shell provides a sorto'f surrounding cushion or buli'er, so that when the tubes a :e thrown about, as is the practice among operatives who use them, the ends are saved from being dent- 5' ed or broken.

For warping purposes it is desirable that the cop-tube be of relatively large diameter in order to maintain the tension of delivery as even as possible. Therefore a cop-tube of such composite structure as described is of great advantage. Large numhess of these tubes are handled daily in the mills, and it is obvious that when light they can be handled much more easily and expeditiously than if solid and massive. Further, the heavier solid spools and tubes are more susceptible to damage, for when thrown about in handling they become chipped and scarred and in use injure the yarn. initially expensive their rapid dcterioration results in great cost of n1aintenance.

As above indicated, my improved cop-tube is ii t, and therefore less liable to damage, and, i irther, is particularly designed to meet the destructive conditions to which such cope subjected. um as my invention '2. in a liangeless cop-tube, the combination with two end pieces 7) 7; having shoulders. 13 w, axial bores 00, cupped inner ends (Jul and one the end pieces formed with transverse LFL recessf, of a fiber shell a arranged with its ends abutting the shoulders c a and its periphery projecting slightly above the periphcries of the end pieces to protect the latter from damage.

in a cylindrical cop-tube, the combina- [ion with n fiber sheii n, of end pieces 7) 7) 1nrztnged with portions cemented within the shell, said end pieces formed with shouldei's e e ntmttin the ends of the sheii and having,

axial bores c Q the dizmieter of the portione of the en( pieces projecting outside the shell being iii iti, than the outside diameter of the shell.

3. in :1 cop-tube, the cornhinzition with :1 iihai sheii In of end pieces 1 arranged to support and protect the shell and said shell projecting: beyond the peripheries; of the end pieces to protect the hittcin, shonldcz'e'c w, abutting the ends of the shell and extensions of the end pieces within ti c sheii.

d. in {L cop-tube, the combination of J fiber shell arranged run-round snitni A In.
