INVENTOR. JOHN SALLY BY 1" I 115 ATTORNEY United States Patent 3,182,619 AUTOMATIC GUIDED SEWING MAfiHINE John Sally, West New York, N.J., assignor to Superior Petticoat Co., Inc., New York, N.Y., a corporation of New York Filed Aug. 21, 1962, Ser. No. 218,246 7 Claims. (Cl. 112-203) This invention relates to a sewing machine, and more particularly to an automatically guided work feed control for joining textile fabric, by sewing, along a predetermined outline paralleling and following the contour of the edge of the fabric, whether such edge is curved, angular, straight, or in any Way irregularly shaped.
It is quite well known that where a fabric having an irregular edge is joined, by sewing, to another fabric, reliance upon a skilled operator who manually guides the pieces of material to be joined is necessary. It at once becomes evident that the operator can operate but a single machine, thus maintaining high labor costs. It has also been the experience in the art that unless the operator is highly skilled in feeding and guiding an irregularly shaped edge of the fabric being sewn, an excessive amount of spoilage can generally be expected.
It is therefore an object of the present invention to provide a completely automatic device in a sewing machine which is adapted to permit continuous sewing of one piece of fabric having an irregular edge to a second piece of fabric. 7 Another object of the present invention is to provide a guiding device in a sewing machine whereby pieces of fabric material may be joined along the edges thereof regardless of whether the configurations of the edge of the fabric are simple or complex.
A further object of this invention is the provision of a guiding apparatus in a sewing machine which will cause a line of stitching to follow the edges of a piece of fabric, whether curved, angular, straight, or irregularly shaped, being fed into a sewing machine.
Another object of the present invention is to provide an improved guiding device, for feeding fabric to be stitched and having an irregular edge into a sewing machine, which is relatively simple and inexpensive in construction and operation, and which can be adapted for use with a conventional sewing machine.
In accomplishing the foregoing and other objects of the present invention, there is provided a reciprocating, movable guide, mounted upon a work surface, adapted to feed a fabric into sewing position in a conventional sewing machine. A reversing motor, geared to the movable guide and responsive to a photoelectric controlled energizing circuit, controls the reciprocating movement of the guide upon 'a transverse plane as the fabric is fed into sewing position in the machine.
Other and further objects and advantages of the present invention will be apparent to those versed in the art from the following description of an embodiment of the invention illustrated in the drawings in which like characters refer to like parts in the several views and in which:
FIG. 1 is a perspective view of an automatic guided sewing apparatus according to the present invention utilized in conjunction with a conventional sewing machine,
FIG. 2 is a schematic diagram of the electrical circuit of the automatic guided sewing device, and
FIG. 3 is an enlarged isometric view of a portion of FIG. 1.
Referring now to the drawings, the embodiment of the present invention is comprised of a sewing machine 10, having a base 11 upon which there is mounted a standard 12 with an arm 13 carrying the usual sewing head 14 at the free end thereof. The sewing head 14 has the usual needle bar 15 carrying the conventional sewing needle 16. A presser foot 17 as provided, having fabric guards 28 and 29 mounted at the lower end of a presser foot bar 18. The base 11 is particularly adapted to comprise conventional feed dogs (not shown), such as are exemplified in the patent to Milligan et al. (U.S. Pat. No. 3,072,081), for feeding a plurality of fabric strips, to be described hereinafter, to the sewing head 14.
Mounted in front of, and parallel to the front of base 11 upon a work surface 19, there is provided a track 20 upon which there is slidably seated a carriage 21 for reciprocating movement parallel to the front base 11. At one end of said carriage 21 there is provided a supporting member 22 mounting a rack gear 23 engageable with a pinion gear 24 driven by a reversing motor 25. Energization of reversing motor 25, presently to be described, imparts a reciprocating movement to rack gear 23 enabling it to move upon a transverse plane. Adjustably mounted upon carriage 21 by screws 26 within spaced apertures 27, or by other securing means, there are provided guide members 30, 31, transversely disposed withrespect to carriage 21, forward of presser foot 18. Guide members 30, 31 are adapted to retain the fabric material in a desired position for feeding into the sewing machine, and each is comprised of an elongated, rigid folded member adapted to receive for traversal between said fold comparatively narrow fabric strips fed therethrough and into the sewing machine. Said guides may also be a channel-like member or may assume a configuration complementary to the material being attached. In the present invention, for purposes of example only, said guide members 30, 31 are illustrated as elongated folded members, one member 31 thereof carrying a lace-like fabric 32 having an irregular edge, and the other member 31 carrying fabric 33 to which it is to be joined. The guide member 31 is particularly adapted to guide the fabric 32 to and between the guard 28 and the guard 29 while the guide 30 is particularly adapted to guide the fabric 33 to and between the base 11 and the guard 29. The presser foot 17 is provided with a slot 17' particularly adapted to be disposed in generally vertical alignment with the needle 16, enabling the needle to join or sew together the fabrics 32, 33. A presser foot guide bar 34 for properly directing fabrics 32, 33 into guide members 30, 31 is further provided.
A light reflecting member, such as a mirror 35, or the like, is particularly adapted to be fixedly positioned upon the guard 29 in any suitable manner. The position of the mirror relative to the needle 16 is of particular importance. The mirror 35 preferably should be positioned forwardly of the needle, that direction being defined by the direction of travel of the fabrics 32, 33 through the machine 10, and laterally to either one or the other side thereof, depending upon the position of that one of the fabrics adapted to traverse the mirror, such as the fabric 32, with respect to the needle 16. Thus, if the fabrics 32, 33 are directed through the machine 10 in the direction indicated in FIG. 1 by the arrow, then the mirror 35 preferably is positioned so that the fabric 32, for example, as indicated above, traverses the same before it traverses or passes under the needle. The mirror is, accordingly, disposed forwardly thereof. And, if the fabric 32 is disposed so that the irregular edge thereof is to pass to the left of the needle 16, in the absence of the present invention, when viewing the machine 10 in the direction indicated by the arrow in FIG. 1, then the mirror 35 preferably is disposed to the left of the needle, construing that terminology in its normal and accepted sense. A beam of light particular importance.
With particular reference now to FIG. 2, it will be seen that the light source supplies a beam of light which is reflected by the mirror 35 to illuminate the sensing device 37, thus generating and thence transmitting a first impulse or signal to a photoelectric cell 38. The cell may be of any suitable construction, particularly adapted to alternately close one of a plurality of circuits depending upon whether the sensor 37 is illuminated or it receives a darkened signal. The first impulse or signal received by the cell 38 enables the latter to close a first circuit, comprising a common line 40, and another line 42. When the beam of light through the sensor 37 is interrupted, a second impulse is generated and transmitted to the cell, enabling the latter to complete a second circuit, comprising the common line 40 and another line 44. It can be seen, therefore, that the reversing motor 25, which may be of any suitable conventional construction, and the cell 38, are each of them operatively associated with and within the first and second circuits.
The carriage is particularly adapted to be reversibly reciprocated longitudinally of the machine by the motor 25, enabling the members and 31 to maintain the irregular-edge of that one of the fabrics 32, 33 presenting such an edge in sewing alignment or substantially immediate juxtaposition relative to the needle 16. To this end, when a portion of substantial transverse dimensional extent of the fabric presenting such an edge is disposed in overlying or superimposed relationship relative to the mirror 35, the beam of light is interrupted. The cell 38 is now particularly adapted to receive the aforesaid second signal, completing one of the first and second circuits, comprising at least the common line 40, causing the rotativc movement of the motor 25, in one of a plurality of directions, and reciprocating the carriage 21, and, thus the guide members 30, 31 generally towards the right, when viewed in the direction of the arrow in FIG. 1. However, when a portion of brief transverse dimensional extent of the fabric traverses the mirror 35, the latter is uncovered. The beam of light from the source 36 is now transmitted to the receiver 37, the latter generating the aforesaid first signal that is transmitted to and received .by the cell 38. The cell 38, having received the first impulse, is particularly adapted to complete the other of the first and second circuits, comprising at least the common line 40, causing rotative movement of the motor 25 in another of said plurality of directions, and reciprocating the carriage 21, and, thus, the guide members 30, 31 generally towards the left when viewed in the direction of the arrow in FIG. 1.
It can be seen, therefore, that the position of the mirror relative to the needle 16, as described above, is of Especially important is the positioning of the mirror generally forwardly of the needle 16,
that direction being defined, as pointed out above, by the direction of the fabrics 32, 33 as they traverse the machine 10. In this manner, the operations described above will be completed by the time a particular substantially instantaneous location of the fabrics pass the location of the mirror and arrive at the location of the needle 16. Thus, every substantially infinitesimal segment of the irregular edge will be disposed in immediate juxtaposition or sewing alignment with respect to the needle. The machine 10 of the present invention will accordingly unusually efficiently and reliably follow the contour of such an irregular edge, regardless of the particular configuration thereof.
A switch 46, which may be of any suitable construction, is particularly adapted to be disposed in the common .line 40, and, accordingly, in operative association with each of the first and second circuits, between the cell 38 and the motor 25. The switch 46 preferably is so constituted and arranged as to be in an open position when the needle 16 is disposed in its lowermost position, joining or sewing together the fabrics 32 and 33, enabling the breaking or opening of that one of the circuits closed or completed by the cell 38 when the needle is in such position. This is of particular significance when it is realized that, in the absence of the switch 46, the fabrics 32 and 33 will direct a force against the needle 16, when the latter is in a sewing or joining position, because of the continued reversible reciprocations of the carriage 21, and the guide members 30 and 31 positioned thereupon. The switch, however, results in incremental reversible reciprocations of the carriage, each increment providing for or presenting a delay that occurs when the needle is in such lowermost or joining position. Accordingly, any force is precluded from being directed against the needle, precluding further any distortion of the fabrics 32, 33. It is to be understood, however, that, while the switch 46 causes the intermittent operation of the motor 25, resulting in the absence of any movement of the fabrics laterally of the direction of travel thereof through the machine 10, the machine remains operative and the fabrics continue to move through or traverse the machine, in the direction indicated by the arrow in FIG. 1.
Although the present invention has been described with respect to a sewing machine, it is within the ambit herein that applicability can be likewise made to staplers, heat and pressure sealing machines and other devices in which it is desirable to move the work beneath a tool in accordance with a predetermined edge.
