To all whom it may concern Be it known that I, J OTHAM S. 001mm, formerly of New York, in the county of New York, and State of New York; at present residing in Hackensack, in the county of Bergeu, and State of ew Jersey, have volved or when at rest.

The feeder 1), instead of being a straight and long bar, as in other machines, is made circular or curved, and without end, and is placed in the machine, represented in the accompanying drawings, directly over the path of the needles, which are shown at a and b.

Pins or points, 0 c 0, project from the outer periphery of the feeder, at or near its lower edge. The ob- Figure 1 is a top view of the machine, with my improvements attached.

My improvements may be applied to any description of sewing-machine, but I have represented them, in the accompanying drawings, as attached to one re cently invented by Sherburne O. Blodgett, of Georgetown, Massachusetts, and which operates with two reciprocating needles penetrating the cloth from opposite sides.

The description and drawings of this machine are already in the Patent Ofiice, and it will not, therefore,

of making the successive stitches; Heretofore, this goods were attached, and which was fed through the snmption of time, and was accompanied by other inconveniences, all of which my present invention is designed to 1'emove.-

My improvement consists in the use of an endless feeder, revolving intermittently, andso constructed as to supply the clothto the needles without the necessity, at any time, of stopping the machine for the purpose of attaching the goods to the feed-bar, as has heretofore been-the case.

To enable others skilled in the art tomake and use my invention, I will proceed to describe the method which I have adopted of carrying it out.

A is the horizontal base-plate or table of the machine, which may be made circular, or of such other mm as circumstances may require. I

O is a vertical flange, cast in one piece with the plate a, and extending above and below it. 7

D is a circular feeder, of the form represented in section in fig, 2. This feeder is so'fitted and applied to the flange O, as to be held in place, and prevented The other parts of the sewing-machine, as they constitute no part of my invention, need not be described, as my improvements may be applied to sewing-machines of any description. I will, however, briefly refer to some of the principal parts of the machine, and point out some of their relative positions. with regard to the rotary feeder and pressure-spring.

It is evidentjthat a cloth-feeder, like that above described, requires no such removal or setting back, as
