WILLIAM A. BAYER AND WILLIAM S. LINCOLN, OF BOSTON, MASSACHU- SETTS, ASSIGNORS, BY MESNE ASSIGNMENTS, TO BAYER 8t LINCOLN SEAMING MACHINE COMPANY.

SEWING-MACHINE.

SPECIFICATION forming part of Reissued Letters Patent No. 9,176, dated April 27, 1880.

Original No. 108,827, dated November 1, 1870. Application for reissue filed March 1, 1880.

To all whom it may concern Be it known that we, WILLIAM ANDERSON BAYER and WILLIAM STILLWELL LINcoLN, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improve- Ineut in Sewing-Machines especially adapted to sew together the ends of piece goods in factories and we hereby declare that the following specification, in connection with the 10 accompanying drawings, will enable others skilled in the art to make and use the same.

Figure 1 represents, in front elevation, our improved apparatus for sewing [fiece goods; Fig. 2, a vertical transverse section of the same, and Fig. 3 a rear elevation thereof.

In the drawings, A represents the wellknown Willcox & Gibbs sewing-machine, a, marking the usual rotatable hook-shaft, and b the usual needle bar, with needle b attached.

The said machine stands on a table, B, at the top of frame 0.

The rotatable annular feeding-plate D, of that particular class usually and properly denominated as a baster'plate, because it has sharp points to enter and positively carry the fabric, is supported in vertical position by the rollers a on studs mounted in the frame 0. This plate D, herein located at the rear of the head a, or that part of the machine in which 0 the usual needle-bar and presser-bar work, has connected with it a side-toothed gear, a, which, engaged by the toothed wheel. (I, rotates the said annular feeding or baster plate, causing it, by its sharp-pointed hooks i, to

carry the fabric along under the needle continuously. These hooks i may be moved toward or from each other on the annular feedin g-plate, according to the width of the fabric to be sewed, said fabric entered-by the said books resting on the shoulder j, that projects fromthe annular plate.

The gear-wheel d is secured to the shaft 6, upon which is a toothed wheel, f, engaged and set in motion by the worm-gear f, or otherwise, from the driving-shaft F, hung in the frame 0, and which may also, by a. belt, g, or otherwise, impart the required motion to the sewing-machine.

The shaft 0 is held in a sliding frame, h, which can be moved by means of the lever G, to throw the gear d into or out of mesh with the teeth of the annular feeding-plate D. The shield E in front covers all but the upper part of the said plate D.

While the sewing-machine A is in operation, the plate D is revolved with the requisite velocity to carry the fabric along continuously at the desired speed, and when two pieces have been nearly connected two more pieces can be hung upon the books as they are in succession brought into position, and so the sewing need not'be interrupted.

The winged wheel, I attached to shaft H, serves to throw the fabric from. the hooks 5 after having been sewed, thus avoiding all liability of carrying the fabric down under the shield E. I

In sewing-machines containing the usual intermittingly-rotated wheel-feed, variations in speed affect, through momentum, the length of stitch, and the power required to run such a feed, and wear of machinery, and the cost of mechanism are all greater than in this our plan, wherein the feed is continuous, which always insures an equal length of stitch and a substantially uniform expenditure of power.

With an annular feeding-plate, as described, provided with points or hooks to penetrate and hold the fabric as it is moved along under the needle, we have combined the well known Willcox & Gibbs class of machine, the hook or looper of which, as it is well known, rotates continuously in one direction, and may be run at the highest speed.

We claim-- 1. The within-described apparatus for sewing together the ends of pieces of fabric for factory use, it consisting, essentially, of the stitchforming mechanism shown and described, the rotatable annular feeding-wheel provided with books to penetrate, carry, and present the fabric positively to the action of the said stitch-. forming mechanism, and means to operate the said feeding-wheel continuously, as described.

2. The annular baster-plate or feeding-wheel, 5 provided with teeth a, the shaft 0, having a pinion at each end, and mechanism by which said wheel to feed the fabric, and mechanism to shaft maybe slid into and out of contact with continuously revolve the baster-Wheel, sub- 10 the said feeding-wheel, combined with the stantially as described.

driving-shaft F, having the worm f thereon, WILLIAM ANDERSON BAYER. 5 all arranged as and for the purposes described. WILLIAM STILLWELL LINOOLN.'

3. The combination, with stitching mechan- Witnesses: ism substantially such as described, of the BENJL W. BARKER,

continuously-revolving annular baster plate or EDWARD L. BROOKS.
