COP-TUBE.
Specification of Letters Patent.
Patented Feb. 18, 1908.
Application filed. Augustl5. 1906. Serial No. 330.686-
supporting and carrying cops or other massesof textile material, particularly in loom shuttles and the like, where the material is removed from the tube by being drawn over its end.
The purpose of my invention is to produce a tube for the purpose indicated, adapted to be positively rather than frictionally driven, susceptible of manufacture at low cost, capable of carrying or supporting on itself a maximum quantity of material, and so formed as to insure complete and even delivery of said material wlthout impediment or restriction.
Figure 1 is a side view of my improved tube showing its characteristic structure; Fig. 2 is a view of the same showing its end formation and particularly the means for positively driving it; Fig. 3 shows the action liable to occur without my improvement; Fig. 4 shows how the disturbing action of Fig. 3 is overcome by my improvement.
The tube A is preferably made of metal, and is formed from a sheet or strip by cutting a piece of a width to roll or form to the circumference of the tube, and by rolling or forming same to a cylinder of the desired diameter ,With a close but unjoined seam :10. At one end a flange a is formed by spinning, forcing or other suitable process, and in this flange is formed a substantially radial indentation or notch l), for engagement with a driving device such as the pin 0, see Fig. 2, projecting from a collar on the spindle d, a part of the machine on which the tube is used. This notch b is preferably formed by the seam x, distended, by the separation of the edges of the metal in the flange.
At the opposite end of the tube, one of the corners of the abutting edges is rounded at 6 so the-yarn or other material in unwinding from the tube passes over the surface of the same and is lifted by that portion terminating in the straight longitudinal edge, so that it does not tend to pass downward to the bottom of the notch, and when it reaches the curved or round edge c it is directed outward so that it may not catch in the seam and be obstructed in its withdrawal from the tube. Fig. 3 shows the obstructive action caused by such a sharp, unbroken corner, and Fig. 4, the merit of my improvement, by permitting the yarn to draw freely over and around such rounding.
The advantages of an unjoined, seamed tube having been fully set forth in my prior application, Serial No. 328,057 filed July 27, 1906, they will not be here considered.
The novel means for preventing the yarn from catching is important, as it effects a substantial saving in time usually lost by stoppage, for piecing and replenishing the supply, thus resulting in material advantage in point of efficiency.
What I desire to claim is:
1. A cop tube of sheet metal cylindrical in form with a close but unjoined seam, and
having at the outer end a straight edge, and
opposite the latter a rounded corner, for the purpose set forth.
2. A cop tube of sheet metal ,with a close but unjoined seam and with a corner of the abutting edges rounded at one end of the tube the opposite edge being straight, and having a flange at one end.
3. A-cop tube of sheet metal, with a close but unjoined seam, having a flange at one end formed up from the metal of the tube, and at the other end of the tube a straight edge and opposite the latter a rounded corner, for the purpose specified.
4. A cop tube of sheet metal, with aclose but unjoined seam, having a flange at one end and means in'said flange whereby the tube may be positively rotated, and at the outer end, a straight edge and a diverging edge with a rounded corner.
5. A cop tube of sheet metal, with a close but unjoined seam, having at one end a flange formed with an indentation whereby the tube may be positively driven, and at the other end of the tube a straight edge and an edge diverging therefrom towards the end and curved to form a rounded corner.
6. A cop tube of sheet metal, with a close opposite the flanged end having a straight 10 but unjoined seam, having at one end a flange edgea-nd a rounded corner, as set forth. with an indentation formed by the seam of In testimony whereof I affiX my signature the tube, and at the other end a straight edge in presence of tWo Witnesses.
5 and a rounded corner as set forth.
7. A cop tube of sheet metal, with a flange SIMON WARDWELL' and with a close but unjoined seam which, in Witnesses: the flange, expands into a substantially ra- CHAS. A. EDDY,
