Definitions

  • This invention is concerned with improvements in sewing machines and is particularly but by no means exclusively concerned with curved hook needle machines for sewing together the uppers and soles of turnshoes.
  • Such a projecting button and presser foot have been found in practice to enable uppers and soles to be sewn together by curved needles having a radius oi curvature of about one inch such as is commonly usedvin machines for sewing together the inseams of welted boots and shoes.
  • the necessity for using such a projecting button and presser foot to deform the sole may be obviated by using a curved needle having a relatively shorter radius of curvature, e. g., of half an inch, the needle can, while passing through the sole Without penetrating completely through the work, strike sufliciently deeply into the sole to ensure that the upper will be firmly sewn thereto.
  • soles made of spongy rubber- In order to allow shoes having very resilient soles to be fed easily through a machine we have observed that, particularly if the soles are thick, it is necessary that the horn be caused to drop an appreciable distance after forming each stitch for feeding the work in order to allow for the re-expansion of the sole which will have been compressed between the horn and a support engaging the upper face of the work, but this gives rise to a tendency, when working around the forepart of the shoe to cause the horn to strike lagainst the inner face of the upper and to drag the margin of the upper away from proper position on the sole, thus increasing the possibility of faulty work and necessitating careful manipulation to offset this tendency.
  • One of the several objects of the present invention is toprovide a sewing machine of the type described with novel and improved work supporting means which will hold the work equally well in either of two different operative relations to the machine and permit the work to be released for intermittent feeding during sewing without undesirably affecting the even progress of the seam.
  • a feature of the invention relates to the provision, in a curved needle machine suitable for sewing unlasted turnshoes, of alternative work supporting means to be used in succession in sewing around the shoe in accordance with the wishes of the operator or with the requirements for holding different portions of the shoe in proper operating relationships.
  • This feature of the vinvention is embodied in a machine ⁇ in which the work supporting means comprises an internal support for engaging the sole of the shoe through the ankle opening and an external support for engaging the upper folded back on the'sole in sewing about the forward part rof the shoe and means for readily moving one of said supports into, andthe other from operative positions.
  • Fig. 1 is a perspective view, looking from the front and from the left hand side of the upper part of the machine embodying the features of the invention, certain parts having been broken away;
  • Fig. 2 is a right hand side view in elevation of a portion of the machine with the work entering horn thereof in operative position and the external work support in inoperative position;
  • Fig. 3 is a similar View showing the external work support in operative position and the work entering horn in inoperative position;
  • Fig. 4 is a view in front elevation of portions of the stitch-forming devices and their operating mech anisms of the machine;
  • Fig. 5 is a view in side elevation similar to that of Fig. 2 illustrating more fully and partly in section the controlling mechanism of the work supporting members; and
  • Fig. 6 is a detail View of certain parts of an adjusting device in the machine as viewed from the right in Fig. 5.
  • the machine illustrated in the drawings is a chain stitch sewing machine having a head casting or frame 2, mounted on a base 4, and provided with bearings 6 near its upper end for a horizontal sewing cam shaft 8, ⁇ arranged to be rotated through a suitable driving and stopping mechanism not shown, and to actuate the various stitch forming and work feeding devices.
  • the curved hooked needle is indicated at IS and is of a relatively small radius, approximately one half inch, and is clamped to a needle segment l2, secured at the right end of a horizontal reciprocating and rocking spindle I4 (Fig. 4).
  • a sleeve Surrounding the left end of the spindle is a sleeve it, which is loosely mounted in a bearing formed in a bifurcated bracket I8 secured to the machine frame 2.
  • the sleeve I6 is clamped on the spindle between a nut 20 threaded on the left end of the spindle and anelongated pinion 22 held in place by a shoulder 24 on the spindle and a key 2S. o
  • the central portion is loosely surrounded by a collar 28 rotatable between the right end of the pinion 22 and a nut 3i) threaded on a sleeve 32 loosely surrounding the right end of the spindle, the sleeve 32 being loose in a bearing at the right of the vbifurcated bracket I8.
  • On the right end of sleeve 32 is formed a segment 34 carrying a needle guide the segment 34 being confined between the right end of bracket I8 and the needle segment l2.
  • the collar 28 is reciprocated by diametri- ⁇ cally opposed pivots 38 on the collar, extending into bearings at the lower forked end of avertically arranged lever 40, fulcrumed at 42 on the frame 2.
  • the upper end of lever 40 is connected by means of a link 44'with the upper end of a lever 46 rotatable about a fixed pivot 48.
  • lever 46 carries a pin 5G on which is loosely mounted a block 52 slidable in a vertical slot 54 in a horizontal slide 5S. Reciprocation of the slide causes reciprocating movement to be imparted to the spindle I4. through the connections thus described.
  • a cam operated lever 58 having a Xed pivot 60 on the machine frame is constructed with a vertical slot 62 along its central portion in which there is secured a block 64.
  • the block 64 carries a rearward projection engaging' a vertical slot formed in an upward extension of the slide 56 to transmit the motion of the lever to the slot in a well known manner. Reciprocation of the slide and feeding movement of the needle may be adjusted by changing the position of the block 64 in the slot of lever 58.
  • the needle guide is actuated by a link '52 having a universal connection at its forward end with the needle guide segment 34, and at its rearward end with a suitable cam actuating lever.
  • a spring 'l5 surrounds the rod and is compressed between the cam actuated lever and a collar on the rod to permit the pleater to yield as it moves forwardly.
  • 'To V provide a yielding engagement of the pleater vertically against the shoe the forward end of the guideway 'i4 is supported by a vertical bolt 11, the lower end of which is slidable in an opening in the guideway.
  • a spring i8 Surrounding the bolt is a spring i8 for maintaining the guideway normally inits lowermost position.
  • the needle In sewing a shoe upper, as indicated at 80 (Figs. 2 and 3), to a sole, indicated at 82, the needle rst engages the horizontal portion of the upper margin held in overlapping relation to the edge of the sole. After entering the sole the needle passes slightly downwardly to the lowest point of a path extending substantially parallel to the surface of the sole, and then upwardly, emerging at the same side of the work at which it entered. The thread is then engaged in the barb of the needle by a looper 84 and retracted to forni a seam wholly at the upper side of the work.
  • the work is clamped against a presser foot by a curved horn-shaped internal work support, the presser foot holding the work in proper relation to the stitch forming devices.
  • the work is moved to an extreme position towards the right and after the needle has pierced the work, the work is freed and the needle is moved towards the left feeding the work with the needle.
  • the work support again acts to clamp the work, and the stitching cycle is repeated.
  • the needle looper 84 lays thread in the needle barb when the needle is at the left end of its feeding movement.
  • the looper is secured to the lower end of a lever 83 (Figs. 1 and 4) pivoted between its ends at 90. for movement in two directions, both forwardly and rearwardly of the machine as well as laterally.
  • the upper end of lever 88 carries cam rolls 92 and 94 engaging peripherally and radially disposed surfaces, respectively, of a cam 90 on the shaft 8.
  • the machine is effective in sewing felt or other soft soled shoes.
  • a sponge rubber or other very resilient sole When a sponge rubber or other very resilient sole is being sewed the downward movement of theA internal work support required to release the shoe about the toe portion during feed may interfere with the upper and displace the shoe from proper operating position, tending to cause faulty work.
