摘要： An electronically controlled multiple pattern sewing machine is provided with the capability of sewing a repetitive sequence of patterns. The sewing machine operator selects, one by one, the patterns desired to be sewn and these are stored in a temporary memory in the order of their selection. In addition, each of the patterns may be modified such as by providing double feed, bight mirror, feed mirror, bight override and/or feed override. The arrangement also allows the operator to replace a previously selected pattern in a string with a different pattern at the same place in the string.

摘要： A twin needle memory device for an electronically controlled sewing machine having a variety of patterns and sewing condition capabilities selectable by means of proximity switch devices. A non-volatile external storage having a one bit capability is provided to retain information as to the last state of the sewing machine, relative to twin needle, upon power interruption; and to provide for proportionate reduced amplification of the bight analog signal in the event that the twin needle mode of operation is selected. Upon reinitiation of power, the state of the external storage is ascertained and used to determine the state of a twin needle flip flop part of the electronic control system of the sewing machine. Subsequent change in twin needle condition is implemented through the proximity switch devices and an additional one second delay count to alter the state of the twin needle flip flop. This alteration in the state of the twin needle flip flop will also alter the state of the non-volatile external storage device.

摘要： A sewing machine is disclosed wherein positioning of the work feeding mechanism and/or needle is controlled by a respective actuator responsive to stitch pattern signals applied thereto. To enable the actuator to complete its positioning for the next stitch prior to repenetration of the needle, the power supplied to the main drive motor of the sewing machine is interrupted until the actuator has completed its task.

摘要： A sewing machine is disclosed in which the pattern of successive needle penetrations during stitching is influenced in accordance with pattern information stored within the machine in a static memory. This pattern information is retrieved and utilized electronically to control, among other factors, the magnitude and direction of feed of the work fabric being stitched. Manually operable electric feed reversing switch means is provided which is effective, while it remains closed, to interrupt utilization of this pattern information to the stitch forming instrumentalities both as to needle bight and work feed motion and to substitute in its place information from auxiliary static memory for use electronically to influence uniform work feed in a reverse direction with the needle maintained in one predetermined lateral position. Provision is also made upon each reopening of the feed reversing switch for reinstating the beginning of that particular pattern of stitches which had been interrupted regardless of where during the course of sewing that stitch pattern the feed reversing switch may have been closed.

摘要： An electronically controlled sewing machine includes an arrangement for utilizing the feed override control to effect a feed balancing function for a pattern having both directions of feed. To effect the balancing function, those patterns which have both forward and reverse feed are "flagged" for recognition by the sewing machine control system. When such a pattern is being sewn, the function of the feed override control is changed to perform the balancing function. Accordingly, when the feed override control is enabled, a fixed increment is added to all forward feeds in the pattern and the feed override control is utilized to attenuate only the forward feeds, to effect a balanced condition.

摘要： A contact-free electrical pulse generator, that utilizes a Hall effect device and a permanent magnet to generate lines of flux and provides two stable output states when cooperating with a flux conducting cam having a stepped peripheral circumference mounted on a rotating shaft is disclosed. The flux conducting cam enhances the flux density imposed upon the Hall effect device when the high portion of the cam becomes proximate the Hall device. The concentrated flux lines flowing through the Hall device changes the state of the device in accordance with the preselected angular positions of the rotary shaft.
