  • BOBBIN WINDERS F OR SEWING MACHINES Filed Jan. 14, 1957 2 Sheets-Sheet 2 IN VEN TOR. Ralph E. Johnson WITNESS gown/V W @W ATTORNEY United States Patent BOBBIN WINDERS FOR SEWING MACHINES Ralph E. Johnson, Mountainside, N.J., assignor to The Singer Manufacturing Company, Elizabeth, N .J., a corporation of New Jersey Filed Jan. 14, 1957, Ser. No. 633,934
  • the present invention relates to sewing machines and particularly to a bobbin winder for sewing machines.
  • I v Fig. 1 is a top plan view of a sewing machine having a bobbin winder constructed in accordance with the present invention.
  • Fig. 2 is a fragmentary view on an enlarged scale of that portion of sewing machine ofFig. l'carrying the bobbin winder.
  • Fig. 3 is a fragmentary plan view of the underside of the top cover plate of the sewing machine of Fig. 1, showing thebobbin winder, which is carried by the top cover plate, in elevation.
  • Fig. 4 is a fragmentary vertical sectional view taken substantially on the line 44 of Fig. 2.
  • Fig. 5 is a fragmentary sectional view taken substantially on the line 55 of Fig. 3, but with the parts shown right side up.
  • Fig. 6 is a fragmentary vertical sectional view taken substantially on the line 66 of Fig. 3, but with the parts shown right side up.
  • Fig. 7 is a fragmentary detail view in section and taken substantially on the line 77 of Fig. 2. 1
  • Fig. 8 is a view similar to Fig. 7 but illustrating a modification of the thread guide.
  • bracket arm 3 The open top of the bracket arm 3 is closed by a cover a conventional hand wheel '10 mounted upon the end of the main shaft (not shown), the hand wheel 10 being mounted outside the machine frame for rotation about an axis longitudinally of the bracket arm 3.
  • a bobbin winder carrier lever 11 is pivotally secured intermediate its ends to the under side of the cover plate 4 by a shouldered pivot screw 12, Fig. 5, extending loosely through the lever 11 and threaded into a tapped hole 13 in the cover plate 4.
  • a stud 14, Fig. 6, arranged at a point spaced from or eccentrically of the pivot screw 12 and adjacent one end of the lever 11 extends upwardly through an enlarged opening 15 in the cover plate 4 and has journaled thereon a spindle 16 which has at its lower end beneath the cover plate 4, the usual wheel 18 having a rubber tire 19.
  • the upper end of the spindle 16 extends upwardly through the opening 15 and is adapted to receive a bobbin 20, illustrated in phantom lines in Fig.
  • the spindle having a flange 21 for sup porting the bobbin and a pin 22 for coupling the bobbin to the spindle 16 for rotation.
  • the spindle 16 is held on the stud 14 by a screw 23 threaded into the upper end of the stud.
  • the side wall of the cover plate 4 is cut away adjacent to the wheel 18 to provide a slot 24, Fig. 3.
  • the pivot screw 12 which constitutes the pivot for the lever 11, is arranged adjacent to the hand wheel 10 and with the axis thereof in a plane normal to the axis of rotation of the hand wheel, and the stud 14 is parallel to the pivot axis of the lever 11, so that upon pivotal movement of the lever, the wheel 18 will be moved through the slot 24 into contact with inner surface of the hand wheel 10 to be rotated.
  • the opening 15 is made large enough so that the flange 21 can passtherethrough in assembly, and
  • slide 25 extendsthrough an opening 27 in the front of the cover plate 4.with the end of the slide 25 bent upwardly to form a finger hold 28.
  • the slide 25 is held in: the guide way 26 by an arm 29 underlying the slide and secured to the cover plate 4 by the screw 12.
  • the arm 29 extends through a slot 30 formed in a depending wall while inward movement of the slide is limited by the enfgagement of a shoulder 34 on the slide against the end of the depending wall 31, as shown in the full line position in Fig. 3.
  • the slide 25 carries a stud 35 about which is coiled a spring 36 having one end extending through an aperture-37 in the slide to anchor it and the other end engaging in agroove 38 formed in the inner edge of the lever 11.
  • the spring is positioned so that upon movement of the slide 25 to its opposite end positions, it will slide along the groove 38 to engage the lever 11 upon opposite sides of the pivot screw 12.
  • the spring 36 biases the lever 11 to its inoperative position, i.'e., with the wheel 18 abutting against the depending wall 31 and out of engagement with the hand wheel 10.
  • the slide 25 is pulled to the dotted line position in Fig. '3, which moves the end of the spring 36 along the groove 38 to the opposite side of the pivot screw 12 and thus biases the lever in opposite direction with the wheel 18 resiliently urged into engagement with the inner surface of the hand wheel 1!).
  • a stationary finger 39 secured to the top of the cover plate 4 by a screw 40 threaded into the hole 13 and arranged to extend between the flanges of the bobbin to engage the thread being wound thereon.
  • the cover plate 4 is made somewhat convex and to accommodate the bobbin winder, the corner thereof at the front of the machine adjacent to the hand wheel 10 has a flat 41 and there is provided a counterbore '42 about the opening that accommodates the flange 21.
  • the spool 9 is mounted on the right hand pin 8 in Fig. 1 and the-thread, designated T, is run through a thread-guide 43 at the free end of the bracket arm 3 and then back towards the bobbin winder.
  • the thread lead is run along the front edge of the cover plate 4 and about an adjustable guide 44 to the bobbin.
  • the guide 44 consists of a stud comprising a sleeve 45 that is arranged substantially normal to the cover plate 4 and secured thereto by a screw 46 extending through an enlarged bore 47 in. the center of the sleeve and threaded into the cover plate 4 with the head 48 of the screw engaging a shoulder 49 formed by counterboring the upper end of the sleeve 45.
  • the sleeve 45 has a lower edge 50 that its formed in' a plane at an angle to the longitudinal axis of the sleeve and -the sleeve is resigned to be seated in a flat or planarsurface 51, Fig. 2, on the cover plate that is normal to the axis of the spindle 14 so that it will be disposed at an angle to a line normal to the surface 51.
  • the lead of the thread T contacts the sleeve '45 at a point along a line longitudinally of the periphery of the sleeve 45 and is Irun around the guide 44 as shown in Fig. 1.
  • a sleeve 45a which comprises a sleeve 45a having a bore 47a that is skewed relatively to the axis of the sleeve, the screw 46 passing through the bore 47a to secure the guide to the cover plate 4, the head 48 of the screw 46 overlying the top 49a of the sleeve.
  • the lower edge 50a of the sleeve 45a is formed at an angle relatively to the axis of the sleeve in the same manner as with the edge 49 of the sleeve45.
  • a bobbin'winder that is substantially concealed for purposes of appearance as well as to protect the mechanism and to prevent undue interference with the manipulation of the work, is dependable, durable, and easy to operate, is simple and economical in construction and being carried entirely by the cover plate, can be easily assembled on the cover plate and this in turn assembled on the machine.
  • an optimum thread pull-oft lead from the thread spool 9 which decreases the tendency of the spool to be spun off its pin 8 as the bobbin is being wound, and an optimum lead to the bobbin which can be readily centered relatively to the bobbin by means of the adjustable guide 44.
  • a further advantage of mounting the bobbin winder on the cover plate 4 is that it will not interfere with the use of any selected drive means.
  • the drive means for the machine is limited since the arrangement of the belt for a treadle drive, or the crank for a hand drive, or the belt or gear connection for a motor drive must be designed around the bobbin winder, which in many cases results in expensive or inferior constructions.
  • the bobbin winder is mounted at the top on the cover plate where it would not interfere with the use of any selected drive means for the machine.
