Abstract
Abstract 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
An electronically controlled multiple pattern sewing machine including a central control system having a memory storing stitch pattern information, pattern selection input means for transmitting to said central control system a pattern selection signal identifying a selected pattern to be sewn by the sewing machine, alteration function input means for transmitting to said central control system selected pattern alteration function commands associated with a selected pattern on an individual basis to cause said central control system to alter the stored stitch pattern information in accordance with said selected pattern alteration function commands so as to sew a selectively altered version of a selected pattern, and pattern string memory means for storing the sequence of entries each comprising a respective pattern selection signal and associated selected pattern alteration function commands.
Claim 2
Dependent Claim
129 words
An electronically controlled multiple pattern sewing machine including a central control system having a memory storing stitch pattern information, pattern selection input means for transmitting to said central control system a pattern selection signal identifying a selected pattern to be sewn by the sewing machine, alteration function input means for transmitting to said central control system selected pattern alteration function commands associated with a selected pattern on an individual basis to cause said central control system to alter the stored stitch pattern information in accordance with said selected pattern alteration function commands so as to sew a selectively altered version of a selected pattern, and pattern string memory means for storing the sequence of entries each comprising a respective pattern selection signal and associated selected pattern alteration function commands.
Claim 3
Dependent Claim
26 words
The sewing machine according to claim 1 further including means for replacing a selected individual entry in said pattern string memory means with another such entry.
Claim 4
Dependent Claim
167 words
The sewing machine according to claim 1 wherein said pattern string memory means includes a plurality of addressable memory locations arranged in a predetermined order and further including: display means for displaying a selected pattern and associated selected pattern alteration functions; first pointer means for identifying the address of a pattern string memory means location; second pointer means for identifying the address of the pattern string memory means location closest to the beginning of said order which is available to accept an entry; an operator actuable enter switch; and means responsive to actuation of said enter switch for (a) advancing the contents of said first pointer means to the contents of said second pointer means, (b) advancing the contents of said second pointer means to the next address in said order, and (c) inserting in said pattern string memory means at the address identified by said first pointer means the pattern selection signal and associated pattern alteration function commands corresponding to the display of said display means.
Claim 5
Dependent Claim
102 words
The sewing machine according to claim 3 further including: an operator actuable memory recall switch; means responsive to actuation of said memory recall switch for setting the contents of said first pointer means to the first address in said order; means responsive to each successive actuation of said memory recall switch for advancing the contents of said first pointer means to a successive address in said order; and means responsive to actuation of said memory recall switch for transmitting to said central control system the contents of the pattern string memory means location identified by the contents of said first pointer means.
Claim 6
Dependent Claim
105 words
The sewing machine according to claim 4 further including: an operator actuable clear switch; a memory recall flag; a clear flag; means responsive to actuation of said memory recall switch for setting said memory recall flag; means responsive to actuation of said clear switch when said memory recall flag is set for setting said clear flag; means responsive to actuation of said enter switch when said clear flag is set for inserting in said pattern string memory means at the address identified by said first pointer means the pattern selection signal and associated pattern alteration function commands corresponding to the display of said display means.
Claim 7
Dependent Claim
42 words
The sewing machine according to claim 5 further including: means responsive to actuation of said clear switch when said clear flag is set for setting the contents of both said first and second pointer means to the first address in said order.
