Abstract

Abstract This disclosure relates to electronically controlled sewing machines and in particular to the combination of such a machine with a re-programmable static memory with which an operator can program in input data representative of a stitch position coordinates for selected patterns, which input data will be encoded into digital form, stored and decoded into input signals for initiating operation of the sewing machine stitch position actuating means to produce patterns corresponding to the operator selected pattern. The re-programmable memory can be located remote from the machine or can be built in as an integral part of the structure of the machine itself. The machine may also contain a static read-only-memory (ROM) having fixed patterns for operation of the machine with or without a re-programmable memory and includes switching means for disconnecting the read-only-memory when the re-programmable memory is connected to the machine.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 229 words
In a sewing machine having stitch forming means operative to form successive stitches including mechanism for influencing the stitch position coordinates of said successive stitches in the formation of a pattern of stitches, logic means responsive to input data representative of stitch position coordinates for producing stitch position coordinate electrical signals, actuating means responsive to signals from said logic means for controlling the position of said stitch forming means in accordance with the input data fed to said logic means, and re-programmable programming means operably connected with said sewing machine, said programming means being responsive to operator manipulation and including read-write static memory means continuously available for storing new digital input data corresponding to a stitch pattern selected by the operator while connected to said sewing machine and for transmitting electrical digital output signals to said logic means such that an operator may select a stitch pattern program for entry into the sewing machine for automatic reproduction of the stitch pattern by the sewing machine, said programming means further including a plurality of selector buttons with each said button being representative of a digital code corresponding to a stitch position coordinate of a stitch pattern and encoder means for converting the digital code generated by each of said buttons of said programming means actuated by an operator into digital input data suitable for storing in said static memory means.
Claim 2
Dependent Claim 229 words
In a sewing machine having stitch forming means operative to form successive stitches including mechanism for influencing the stitch position coordinates of said successive stitches in the formation of a pattern of stitches, logic means responsive to input data representative of stitch position coordinates for producing stitch position coordinate electrical signals, actuating means responsive to signals from said logic means for controlling the position of said stitch forming means in accordance with the input data fed to said logic means, and re-programmable programming means operably connected with said sewing machine, said programming means being responsive to operator manipulation and including read-write static memory means continuously available for storing new digital input data corresponding to a stitch pattern selected by the operator while connected to said sewing machine and for transmitting electrical digital output signals to said logic means such that an operator may select a stitch pattern program for entry into the sewing machine for automatic reproduction of the stitch pattern by the sewing machine, said programming means further including a plurality of selector buttons with each said button being representative of a digital code corresponding to a stitch position coordinate of a stitch pattern and encoder means for converting the digital code generated by each of said buttons of said programming means actuated by an operator into digital input data suitable for storing in said static memory means.
Claim 3
Dependent Claim 32 words
In a sewing machine as recited in claim 1 wherein each said button is representative of a digital code for the bight and feed of a stitch coordinate of a stitch pattern.
Claim 4
Dependent Claim 26 words
In a sewing machine as recited in claim 1 wherein said selector buttons are aligned in array such that the operator can visualize a pattern thereon.
Claim 5
Dependent Claim 28 words
In a sewing machine as recited in claim 1 wherein each said button is capable of providing a discrete output voltage different from any other of said buttons.
Claim 6
Dependent Claim 19 words
In a sewing machine as recited in claim 4 wherein said memory means comprises a static random access memory.
Claim 7
Dependent Claim 33 words
In a sewing machine as recited in claim 1 wherein said programming means is disposed remote from said sewing machine and is electrically connected thereto, and is readily detachable from said sewing machine.
Claim 8
Dependent Claim 19 words
In a sewing machine as recited in claim 1 wherein said programming means is integral with said sewing machine.
Claim 9
Dependent Claim 229 words
A programmable memory unit for a sewing machine having a stitch forming means operative to form successive stitches, including mechanism for influencing the stitch position coordinates of said successive stitches in the formation of a pattern of stitches, logic means responsive to input data representative of stitch position coordinates for producing stitch position coordinate electric signals, actuating means responsive to signals from said logic means for controlling the position of said stitch forming means in accordance with input data fed to said logic means, and means for initiating actuation of successive stitches in the formation of said pattern of stitches, said programmable memory unit comprising: means responsive to operator manipulation for programming a stitch pattern selected by an operator, said programming means including a plurality of selector buttons with each of said buttons having the capability of generating a digital code corresponding to a stitch position coordinate of a stitch pattern; read-write static memory means continuously available for storing new digital input data corresponding to stitch position coordinates of a stitch pattern selected by an operator; encoder means for converting the digital code generated by each of said buttons of said programming means actuated by an operator into digital input data suitable for storing in said static memory means; and, means for coupling said programmable memory unit to said initiating means and said logic means of said sewing machine.
