Syllabus

<p>Claim 2 of reissued letters-patent No. 9097, granted- to -Louis Dryfoos, assignee of August Beck, February 24, 1880, for an “ improvement in quilting machines,” namely, “ 2. The combination, with a series of vertically reciprocating needles mounted in a laterally reciprocating sewing-frame, of conical feed-rolls, and mechanism for causing them, to act intermittingly during the intervals between the formation of stitches, substantially as herein shown and described,” is not infringed by a machine which has no conical rollers, but has short cylindrical feed-rollers at each edge of the goods, which they feed in a circular direction by moving at different rates of speed constantly, the needles having a forward movement corresponding to that of the cloth while the needles are in it, nor by a machine which has the well-known sewing-machine four-motion feed, which is capable of feeding in a circular direction by lengthening the feed at the longest edge of the goods.</p>
