Abstract: A needle position detector for a sewing machine includes a pair of disk-like members axially mounted on a rotary shaft coupled to the armshaft of the sewing machine. Each of the disk-like members is provided with an optically nonreflective portion occupying a greater area of its circumference and an optically reflective portion occupying a smaller area of the circumference. The disk-like members are adjusted so that the angular positions of the respective reflective portions correspond to the upper and lower needle positions. A light emitting element is associated with each of the disk-like members to emit light in a radial direction thereto. A light sensitive element is also associated with each disk-like member to receive light reflected from the reflective portion of the associated disk-like member to generate a needle position signal.

Abstract: A device for feeding tape, elastic strips or the like in a sewing machine that functions in timed relation with the mechanism for advancing a workpiece during seaming. The device includes elements for sensing the machine's operating speed and the amount of workpiece advance during each revolution of the machine's main shaft. A control unit having a microprocessor is operatively connected to the sensing elements and is effective in controlling a motor associated with the feed rollers for the tapes etc. so that they are rotated by an amount governed by the control unit. A feed back response to the control unit provides the information on roller rotation so that a comparison can be made with information previously received whereby the control unit is capable of initiating a correction for possible differences that may exist when the actual rotational speed of the rollers is greater or less than that required for the desired manner of application of tape or elastic strips to a workpiece.

The lift lever is carried on a selectively shiftable pintle supported by the sewing machine frame, the pintle having a first shiftable position in which the lug extending from the needle bar lever does not engage with the second end of the lift lever and a second shiftable position in which the lug does engage with the second end of the lift lever whereby the lug will effect rotation of the lift lever and have the first end elevate the presser foot out of pressure contact with the work material.

Abstract: An athletic sweatband generally consisting of a continuous band of material disposable about the wrist, head or ankle of a user, the band having an interior compartment communicable with the exterior of the band through an opening in the band, and an article container disposed in the band compartment having an opening communicable with the band opening.

Abstract: An industrial automatic pattern stitching sewing machine in which the speed of a cloth holder feeding cloth at a sewing needle is limited to a predetermined maximum speed in any direction so that the movement of the cloth holder is always in synchronization with that of the sewing needle. With this arrangement, pattern irregularities and jamming caused by nonsynchronization between the cloth holder and sewing needle are eliminated. Pulse numbers from a stored stitching pattern are examined to determine which of the X and Y pulse numbers is the larger. The larger of these is compared with a stored maximum value. If the larger number is less than the stored value, the two pulse numbers are outputted directly. Otherwise, at least one of them is limited to the maximum value.

Abstract: An electronic sewing machine with a computer (10) for the sewing of a selected fancy seam has electronic circuits to bring about a breaking of a control circuit of the motor (11) of the machine, when the selected seam is completed, and further to detect the "O"-position of a motor control (16) and in this position to re-engage the control circuit and initiate starting codes in the computer for repetition of the selected fancy seam, when the motor is restarted.

Abstract: A buttonhole sewing machine for automatically forming a buttonhole including right and left parallel side stitching parts, and another stitching part connected to the side stitching parts. The machine has a switch for detecting front and rear ends of each side stitching part, and is capable of sewing the buttonhole in divided parts on opposite sides of a longitudinal centerline thereof so that the two side stitching parts are stitched in the same work feeding direction. The machine comprises a control circuit generating a feed change signal when the number of stitches being formed in one of the side stitching parts has become equal the total number of stitches of the other side stitching part less a predetermined number, and a feed adjusting circuit for reducing a work feeding increment for a time interval between generation of the change signal and a signal from the switch, to avoid a difference in length between the side stitching parts.

Abstract: An apparatus and method for implementing bobbin winding in place in a looptaker of a sewing machine. When a presser foot lift lever is manipulated to elevate a presser foot, and the sewing machine motor is activated, a series of two or three endwise reciprocations of the sewing machine is effected to bring an upper thread to the lower thread carrying bobbin, after which further endwise reciprocation of the sewing needle is held in abeyance while actuation of the sewing machine motor is continued, to provide the least disturbance of upper thread passage to the lower thread bobbin. No other bobbin winding signaling steps are required.

Abstract: A method of forming a stitch pattern is disclosed in which at least two closely spaced or coincident end stitches are present. The overall pattern is divided into overlapping block sections. In one block, a first group of stitches is formed followed by a second group of stitches being formed in an adjacent block. The number of stitches between closely spaced or coincident stitches that results is reduced. Therefore the accumulated error of fabric feeding pitches and the distance between the two end stitches is reduced resulting in a more precisely constructed overall pattern.

Abstract: During stitching a pattern, there is often issued a designation to change the pattern under forming to the other. In such a case total load on a fabric feed control motor and a needle amplitude control motor is temporarily increased. A microcomputer which controls driving of these motors, discriminates the new designation and rotating phase of the sewing machine and drives the fabric feed control motor by means of specific data by mean value of the maximum and the minimum fabric feed control data, instead of the fabric feed control data which is first read out next to said designation.

Abstract: A sewing machine in which the start and stop of a main shaft is controlled by a cam mechanism through a motion control mechanism at the sewing cycle corresponding to a predetermined number of stitches. The working position of a work holder is controlled by positional data in original instructions stored in a memory. Additional instruction corresponding to the number of stitches to reach the next stop time point controlled by the cam mechanism is prepared for back-tacking, unless the number of stitches corresponding to the original instructions are equal to an integral multiple of the predetermined number of stitches.

Abstract: A specially configured and dimensioned bracket is inserted through the strap slot at one side end of a goggles frame. A plurality of transparencies are installed over the lens, one at a time. Peripheral tabs on the lens shaped portion of each transparency are inserted between the lens and the goggles frame. A retaining pin extending from the bracket is forced through a small hole formed in the inner end of an arm portion which extends from one end of the lens portion of the transparency. The arm portion of the transparency is folded back on itself so that the retaining pin extends through a large hole in the outer end of the arm portion. The arm portion of the outermost transparency is not folded but is left free to be grasped with one hand so that the transparency can be torn away from the goggles frame when soiled, thereby enhancing a racer's vision. When this is done, the arm portion of the outermost transparency just uncovered unfolds but remains attached to the retaining pin.
