SIMON W. WARDWELL, OF PROVIDENCE, RI-IODE ISLAND.
COP-TUBE.
Specification of Letters Patent.
Patented Feb. 11, 1908.
Application filed September 21 1906- Serial No. 335.630.
To all whom it may concern:
Be it known that I, SIMON W. WARDWELL, a citizen of the United States, residing at Provi dence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Cop-Tubes, of
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 without 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 00. 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, a part of the machine on which the tube is used. This notch is preferably formed by the seam ac, 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 turned slightly inward at f, so the yarn or other material, on being delivered, may not catch in the seam and be obstructed in its with drawal from the tube. Fig. 8 shows the obstructive action caused by such a corner 4 when sharp or unrelieved, and Fig. 4 the merit of my improvement by permitting the yarn to freely draw over a corner relieved in the manner indicated.
The novel means for preventing the yarn from catching is important, as it effects a substantial saving in the time usually lost by stoppage, for piecing and replenishing the supply, thus resulting in material advantage in point of efliciency. Further, when used with a notched spindle the lip formed by turning in the edge will abut the edge of the notch so as to constitute a driver, while it further being of a vielding character tends to frictionally hold the tube longitudinally in place upon the spindle.
What I desire to claim is:
1. A cop tube of sheet metal in cylindrical form, with a close but unjoined seam and with a corner of the abutting edges turned inward toward the interior of the tube in the manner and for the purpose specified.
2. 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 corner of the abutting edges turned inward toward the interior of the tube, in the manner and for the purpose specified.
3. A cop tube of sheet metal with a close but unjoined seam, having a flange at one end, and means in said flange whereby the tube may be positively rotated, and at the opposite end a corner of the abutting edges turned inward toward the interior of the tube, in the manner and for the purpose 5. A cop tube of sheet metal, With a close but unjoined seam, having at one end a flange with an indentation formed by the seam of the tube, and at the other end a corner of the abutting edges turned inward to ward the interior of the tube, in the manner and for the purpose specified.
6. A oop tube of sheet metal, With a flange and With a close but unjoined seam, Which in the flange expands into a substantially radial notch or indentation, and at the end opposite I the flanged end having a corner of the abutting edges turned inward toward the interior of the tube, in the manner and for the purpose specified.
In testimony Whereof I aflix my signature in presence of tWo Witnesses.
