(01. 242-39) 1 2 This invention relates to yarn winding and reference numerals refer to the same or similar packaging machines, and relates more particu elements in the respective views. In the drawing: Figure 1 is a perspective view of the clutch and‘ larly to improved means adapted to be applied to a yarn winding and packaging machine for stop ping the winding of yarn on to the package when the package has attained a predetermined size. It is an object of this invention to provide an improved device adapted to be applied to a yarn brake of a cone winding machine having a pack age size control gauge, constructed in accordance with our invention, applied thereto, Figure 2 is a detail view, partly in section. show winding machine for automatically and instantly ing the relationship of the traverse bar, traverse stopping the winding of the yarn on to the pack 10 frame dog and the sizing gauge, age when the package has attained a predeter mined size. Another object of this invention is to provide, in a yarn winding machine, an improved stop Figure 3 is a cross-sectional View taken ‘on the line 3-3 of Figure 2, Figure 4 is a cross-sectional view taken on the , line 4—4 of Figure 3 and in a direction opposite ping mechanism, responsive to the size of the 15 to that of Figure 2, and ‘package being wound, for halting the winding Figure 5 is a detail view of the gauge of our operation and preventing the building up of the package to a point where the thread guide presses invention showing the striking face. Referring more particularly to the drawing, the on the outside windings of the package to mar reference numeral I indicates standards on the 20 main frame of a winding machine in which is Other objects of this invention will appear from journaled a main shaft 2 adapted to rotate spin the following detailed description and drawing. dle 2' and the package of yarn 3 being wound In yarn winding and packaging devices, as supported on said spindle. This main shaft 2 is the same. equipped with a driving pulley 4 adapted. to be heretofore commonly constructed, it was found necessary to stop the, winding machines during 25 rotated by a belt 5 when said belt is held in con lunch periods or change-of-shift periods in order to prevent the production of oversized packages tact therewith by idler pulley 6. Idler pulley 6 is journaled in‘one end of an arm 1 the other end of which rotates on a stud shaft 8 mounted in a and/or damaged packages caused by the thread guide rubbing against the outside windings of bracket 9 that is part of the main frame I. This oversized packages. By employing the improved 30 main shaft 2 also has a brake drum ll attached stopping mechanism of the present invention, not thereto. ‘a only are improved packages of yarn produced, but it is also not necessary for the operator to be A clutch lever rod l2 extends across the top of the frame I from front to rear. On the rear end of lever rod I2 is a cam face l3, which is adapted present during the winding of the complete pack age. Since the winding machine runs continu 35 to act as the idler pulley arm lifter, while on the ously from the start until the package has reached front end is a brake lever l4 arcuate in shape. its predetermined size, a better package is pro duced than where the machine is stopped, slowed down or the traverse of the yarn is otherwise dis The brake lever l4 carries a brake [5 adapted to cooperate with the brake drum H in operative position. A catch [6 is provided for cooperation turbed during the building of the package. As 40 with an abutment I‘! on a lever l8 to maintain the is well known, a change of speed in the machine _ brake in inoperative position out of contact with during the Winding operation invariably alters drum II. the throw of the yarn at each end of the traverse stroke thus effecting the build of the ends of the dog segment 19 that is pivoted to the main frame package. The lever [B is part of a traverse frame on a stud shaft 2|. 45 The winding machine is also equipped with a traverse frame a part of which is indicated by the reference numeral 22. In general, this traverse traverse frame dog of a winding machine, said frame is mounted on the cam shaft bushing, thus gauge presenting a working face positioned at an being pivoted about the hub 23 and provides a angle to the traverse bar, thus permitting the as 50 support and guide for the remainder of the trav sembly of a winding machine the operation of erse mechanism. A guide 24 formed at the top of which is automatically controlled by the size of the traverse frame 22 controls the movement of the package. a traverse bar 25 that has attached thereto a A preferred embodiment of our invention is yarn guide supporting rod 26 carrying a yarn shown in the accompanying drawing wherein like 65 guide 21. The traverse bar 25 is reciprocated by . In accordance with our invention, we construct a package size control gauge for application to a 2,404,838 3 4 a cam (not shown) to control the path of the yarn It is to be understood that the foregoing de on the package being formed, while the whole tailed description is given merely by way of il traverse frame 22 rotates clockwise, as seen in Figure l, as the package is built. therein without departing from the spirit of our . The rotation of main shaft 2, and with it the rotation of spindle 2’, is halted by the traverse bar 25 cooperating with a package size control lustration and that many variations may be made D invention. , Having described our invention, what we desire to secure by Letters Patent is: 1. In a yarn package winding machine com prising a drive for rotating the package, brak the extension of traverse frame dog segment I9 and held thereon by a set screw 29. Thus, when 10. ing means adapted to stop the rotation of said package, a traverse bar having a square end and package 3 has reached its predetermined size the yarn guide for traversing the yarn on said pack traverse bar will have been moved to such a age, and means including a traverse frame dog position that the point 3| thereof will strike near segment for holding said braking means in inop the middle of face 32 of gauge 28 causing the ro erative position, a gauge mounted on said traverse tation of lever I8 about stud shaft 2I, which rota frame dog segment for cooperating with sai tion releases brake lever [4. The free brake lever gauge 28 placed in a predetermined position on I4 is pulled counter-clockwise by any suitable means, such as a spring or a weight (not shown), traverse bar to throw said braking into operativ position to halt the winding operation when sai package has reached a predetermined size, said thus rotating lever rod I2 to apply brake I5 to drum II, and at the same time causing cam I3 20 gauge comprising a member having a beveled edge cut away at one end thereof to form a striking to lift idler pulley 6 from the belt 5 which action face for coming into contact with one corner at effects the removal of the belt from the surface of the drive pulley 4. By grinding the face 32 of gauge 28 to a cer ‘tain'contour, no detrimental effects are produced on the package by the striking of traverse bar 25 against gauge 28 to halt the winding operation ‘when the package has reached its predetermined size. To produce the desired results we have found that the face 32 should have an angle of slope which ranges from 121/2 degrees vertical and 30 degrees horizontal to-1'71/2 degrees vertical and 25 degrees horizontal, highly satisfactory re ‘sults being obtained when the angle of slope of face 32 is 171/2 degrees vertical and 271/; degrees horizontal. It is preferable that the face lie in a single plane. The angles forming the slope of the striking face lie and are measured as shown in Figure 5 of the drawing, the horizontal angle the end of said traverse bar, the striking face being in a single plane sloping from 121/2 degrees vertical and 30 degrees horizontal to 171/; degrees vertical and 25 degrees horizontal and being at an angle to the plane of said beveled edge. 2. In a yarn package winding machine com prising a drive for rotating the package, braking means adapted to stop the rotation of said pack age, a traverse bar having a square end and yarn guide for traversing the yarn on said package, and means including a traverse frame dog seg ment for holding said braking means in inopera tive position, a gauge mounted on said traverse frame dog segment for cooperating with said traverse bar to throw said braking into operative position to halt the winding operation when said package has reached a predetermined size, said which may vary from 25° to 30° being indicated 40 gauge comprising a member having a beveled by reference character A and the vertical angle edge cut away at one end thereof to form a strik ‘which may vary from l21/2° to 17 1/2" being indi ing face for coming into contact with one corner cated by reference character B. These angles at the end of said traverse bar, the striking face being in a Single plane sloping 171/2 degrees verti are conditional upon the point 3I being formed by ending the traverse bar 25 at right angles to cal and 271/2 degrees horizontal and being at an angle to the plane of said beveled edge. ‘its aXis. If the corner or point 3I is ground to ‘an angle, obviously this would require a compen sating change in the angle of slope of the face 32. The gauge is preferably made of hot rolled steel, case hardened, but may be made of other types of steel alloys such as tool steel, etc. ' JOHN LEE HALL. ANGELO M. SANTOLLA.
