Abstract
Abstract A basting stitch mechanism in a zigzag sewing machine utilizing a latch carried by a needle bar selectively to connect and disconnect the actuating mechanism of the sewing machine to drive the needle bar in endwise reciprocation. To impart zigzag motion to the needle, the needle bar is supported for endwise reciprocation in a gate journaled for lateral oscillation about an axis inclined to the axis of needle bar reciprocation. This arrangement amplifies the relative motion between the needle bar and the gate so that it may be utilized during an extreme lateral excursion of the gate to trip the latch mechanism carried by the needle bar by means of an abutment member mounted on the gate. By mounting the gate in a supporting bracket which is attachable to the sewing machine, the gate, needle bar and basting stitch mechanism may be subassembled and partially adjusted prior to installation into the sewing machine with only simple adjustments required after installation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A skip stitch mechanism in a sewing machine having a frame, an endwise reciprocating needle bar, a gate supporting said endwise reciprocating needle bar, latching means carried on said needle bar, actuating mechanism carried in said sewing machine frame, means driven by said actuating mechanism for imparting endwise reciprocation to sAid needle bar through said latching means, and means for imparting lateral jogging motion to said gate; the improvement comprising, a. means for influencing relative motion between said gate and said needle bar during lateral jogging motion of said gate, and b. abutment means carried by said gate and responsive to said motion relative to said needle bar during said lateral jogging to unlatch said latching means on said needle bar from said actuating means.
Claim 2
Dependent Claim
125 words
A skip stitch mechanism in a sewing machine having a frame, an endwise reciprocating needle bar, a gate supporting said endwise reciprocating needle bar, latching means carried on said needle bar, actuating mechanism carried in said sewing machine frame, means driven by said actuating mechanism for imparting endwise reciprocation to sAid needle bar through said latching means, and means for imparting lateral jogging motion to said gate; the improvement comprising, a. means for influencing relative motion between said gate and said needle bar during lateral jogging motion of said gate, and b. abutment means carried by said gate and responsive to said motion relative to said needle bar during said lateral jogging to unlatch said latching means on said needle bar from said actuating means.
Claim 3
Dependent Claim
84 words
A skip stitch mechanism as claimed in claim 1 wherein said means for influencing relative motion between said gate and said needle bar includes an upper and a lower bearing, said upper bearing having a bearing surface supporting said gate in said sewing machine frame and having a coaxial internal bearing surface for said needle bar, said lower bearing having a bearing surface supporting said gate in said sewing machine frame spaced from an internal bearing surface for said needle bar in said gate.
Claim 4
Dependent Claim
151 words
A skip stitch mechanism in a sewing machine having a frame, an endwise reciprocating needle bar, a gate supporting said endwise reciprocating needle bar, latching means carried on said needle bar, actuating mechanism carried in said sewing machine frame, means driven by said actuating mechanism for imparting endwise reciprocation to said needle bar through said latching means and mechanism driven by said actuating mechanism for imparting lateral jogging motion to said gate and said needle bar; the improvement comprising: a. means for influencing relative motion between said gate and said needle bar when said gate is imparted lateral jogging motion by said acutating mechanism, and, b. abutment means carried by said gate and responsive to said motion relative to said needle bar during an extreme excursion of said lateral jogging to unlatch said latching means on said needle bar from said actuating means which imparts endwise reciprocation of said needle bar.
Claim 5
Dependent Claim
151 words
A skip stitch mechanism in a sewing machine having a frame, an endwise reciprocating needle bar, a gate supporting said endwise reciprocating needle bar, latching means carried on said needle bar, actuating mechanism carried in said sewing machine frame, means driven by said actuating mechanism for imparting endwise reciprocation to said needle bar through said latching means and mechanism driven by said actuating mechanism for imparting lateral jogging motion to said gate and said needle bar; the improvement comprising: a. means for influencing relative motion between said gate and said needle bar when said gate is imparted lateral jogging motion by said acutating mechanism, and, b. abutment means carried by said gate and responsive to said motion relative to said needle bar during an extreme excursion of said lateral jogging to unlatch said latching means on said needle bar from said actuating means which imparts endwise reciprocation of said needle bar.
Claim 6
Dependent Claim
167 words
A skip stitch mechanism in a sewing machine having a frame, an endwise reciprocating needle bar, a gate supporting said endwise reciprocating needle bar, latching means carried on said needle bar, actuating mechanism carried in said sewing machine frame, means driven by said actuating mechanism for imparting endwise reciprocation to said needle bar through said latching means and mechanism driven by said actuating mechanism for imparting lateral jogging motion to said gate and said needle bar; the improvement comprising: a. a supporting bracket attachable to said sewing machine frame, b. means mounting said gate in said supporting bracket for motion relative to said needle bar when driven by said actuating mechanism to impart lateral jogging motion to said needle bar, and c. abutment means carried by said gate and responsive to said motion relative to said needle bar during an extreme excursion of said lateral jogging to unlatch said latch means on said needle bar from said actuating means which imparts endwise reciprocation to said needle bar.
Claim 7
Dependent Claim
167 words
A skip stitch mechanism in a sewing machine having a frame, an endwise reciprocating needle bar, a gate supporting said endwise reciprocating needle bar, latching means carried on said needle bar, actuating mechanism carried in said sewing machine frame, means driven by said actuating mechanism for imparting endwise reciprocation to said needle bar through said latching means and mechanism driven by said actuating mechanism for imparting lateral jogging motion to said gate and said needle bar; the improvement comprising: a. a supporting bracket attachable to said sewing machine frame, b. means mounting said gate in said supporting bracket for motion relative to said needle bar when driven by said actuating mechanism to impart lateral jogging motion to said needle bar, and c. abutment means carried by said gate and responsive to said motion relative to said needle bar during an extreme excursion of said lateral jogging to unlatch said latch means on said needle bar from said actuating means which imparts endwise reciprocation to said needle bar.
Claim 8
Dependent Claim
