Definitions

  • This invention relates to improvements in thread-guide rolls, and more particularly in guide rolls for waxed thread shoe sewing or other machines employing thread treated w th materials capable of solidifying.
  • the ob ect of the invention is to provide a thread-guide roll for a machine of the type referred to which will be freely rotatable at all times and will not be susceptible to stick ng or binding on its mounting stud by reason of solid fied wax .or other materials.
  • Other objects are to provldc a thread-guide roll and a mounting stud, the contactmg bearing surfaces of which may be lubricated or treated with solvent in a more effective manner than heretofore to free the roll for rotation when material capable of solidifying is deposited between the bearing surfaces.
  • a still further object is to provide a thread-guide roll WhlCh is more durable in use than prior rolls because of a greater facility in applying lubricant thereto and a greater than usual freedom from accumulations of solidified thread-treating material or entrapped abrasive materials.
  • the improved thread-guide roll is incorporated in a sewing machine having devices for tensioning and imparting an intermittent motion to the thread, the intermittently tensioned thread-passing about the roll.
  • a series of spokes having their ends provided with bearing surfaces and cutting edges to scrape the bearing surfaces for the ends of the spokes free from solidified deposits of thread-treating material. In this way the bearing surfaces both on the spokes and for the roll are kept free from deposits of solidified material.
  • recesses are cut in the rolls between the spokes to provide receptacles for solidified material scraped by the cutting edges from the bearing surfaces.
  • the recesses between the spokes of the roll also provide reservoirs for lubricating and solvent liquid so that relatively large quantities of such liquid may be brought into direct contact with the bearing surfaces between the stud and the ends of the spokes.
  • Fig. l is a view in right side elevation of a portion of an automatic Goodyear welt shoe sewing machine in which rolls constructed in accordance with the present invention are incorporated;
  • Fig. 2 is a perspective, exploded view on an enlarged scale showing the construction of one of the thread-guide rFolls 1and its mounting stud employed in the machine of Fig. 3 is a side view of one of the-rolls in end elevation, partly broken away;
  • Fig. 4 is a sectional view of the take-up roll shown in Fig. 3 taken along the line IV-IV;
  • Fig. 5 is a perspective view partly broken away and on an enlarged scale, indicating the manner in which the improved roll clears the bearing surfaces of deposits of adhering solidified material, in which lubricant is applied to the bearing surfaces for the roll.
  • these rolls are heated to prevent accumulation of solidified thread-treating wax so that the friction reducing character of the rolls will be maintained and the stitches of a seam may be inserted with uniformity'in the work operated upon.
  • it is necessary to apply relatively large quantities of lubricating liquid or wax dissolving solvent to the rolls where high-quality work is required. In many instances, excess lubricating liquid will be transferred to the surfaces of a shose causing damage or discoloration. If the rolls are heated, accumulations of wax sometimes decompose into a hardened mass, requiring removal of the rolls from the machine and scraping of the bearing surfaces.
  • the work operated upon comprises a shoe upper 6, an insole 8, and a welt 10, through which passes a curved hook needle 12.
  • the needle oscillates toward and from the work to carry through it loops of thread 14 passing over guide rolls 16, 18 and 20.
  • the thread is drawn toward the guide roll 20 from a tension wheel 22 for imparting a uniform resistance to movement of the thread in accordance with accepted sewing practices.
  • the guide roll 18 is mounted on a take-up 24 and the thread engages the guide roll 18 between the rolls 16 and 20, the motion of the take-up corresponding to the requirements of the other stitch-forming devices.
  • the thread Before reaching the tension wheel 22 the thread passes from a supply (not shown) into a wax or other thread lubricant containing pot 26.
  • the wax in the pot is in liquid form, but is capable of solidifying either through cooling or evaporation of a solvent.
  • the machine is similar to that disclosed in United States Letters Patent No. 2,359,662, granted October 3, 1944, upon application of A. R. Morrill.
  • each roll is constructed without any solid hub, but with a series of individual spokes 28 having their inner ends disconnected and formed with concave cylindrical surfaces engaging loosely with the cylindrical outer bearing surface of a supporting stud 30.
  • the stud 30 is disposed at right angles to the path of the thread passing from the tension wheel and is secured in the respective part of the machine.
  • the stud securing part is a fixed bracket 32 into which the stud 30 is threaded.
  • the roll 18 it is the take-up. 24, and in the. case of the roll 20 it is a resilient, auxiliary take-up 34.
  • Each roll is surrounded by a circumferentially slotted cage 36, which entirely encloses one axial end of the roll.
  • each roll is a series of recesses 37 to provide clearance spaces for loose solidified material and the inner ends of the spokes are outlined by cutting edges 38 (see Fig. 5) extending axially of the stud 30 and acting to scrape the solidified material from the bearing surfaces of the stud 30 during rotation of the roll.
  • each roll has two separate series of spokes 28, one series at each axial end of the roll.
  • the construction of the spokes in two series is accomplished by forming the recesses 37 as circular bores extending throughout the full axial length of the roll in parallel relation to its axis and then cutting out the center of the roll until the bores are intersected.
  • the central part only of the roll is then recessed further providing a circumferential internal groove 40 dividing the spokes into two series.
  • the internal cylindrical surfaces of the groove 40 are relatively wider in circumferential direction than the ends of the spokes 28.
  • edges of the cylindrical surfaces of the groove 40 between the recesses 37 also act as cutters to remove projecting solidified material adhering to the stud 30 in the manner indicated in Fig. 5.
  • the solidified wax or other material broken off the stud eventually finds its way out through the ends of the recesses 37, the recesses communicating with the grooves to provide means of egress for the solidified wax scraped from the stud by the spokes.
  • each roll is partially covered by the enlarged head, indicated at 42 on the stud 30.
  • the head 42 overlaps the major portion of each recess 38, so that when 'the'machine is at rest the portions of the recesses remaining uncovered are readily accessible for oiling or insertion of solvent as by a hand-operated container 44 (Fig. 5).
  • Eachfrecess connects directly with all of 'theinternal bearingsurfaces of the'rolls and communicates directly with 'the circumferential groove 40 to insure complete lubrication for all these surfaces by reason of the circumferential recesses afford storage capacity for quantities of oil sufficient forlong periods of machine operation.
  • the rolls of the inventon enable the Jmachine to operate more appreciably with less attention on the part of the operator and contribute effectively to the general efficiency in uniform and attention free machine operation.
  • Such machines include winding machines, especially for forming bobbins or other waxed thread packages.
  • a machine having a device for tensioning a thread treated withrnaterial capable of solidifying,the'cornbination with a stud disposed at-right angles to the path of the thread passing from the tensioning device and a guide roll 'on the stud'about whichthe thread passes from the tensioning device formed with a series of spokes having their inner ends formed'with bearing surfaces engaging the stud and provided with-cutting edges to maintain the bearing surfaces of the stud and roll free from deposits of threadtreating material.
