EYELET-HOLE ATTACHMENT FORSEWlNG-MACHINES.

SPECIFICATION forming'part of Letters Patent No. 227,640, dated May 18, 1880.

Application filed February 9, 1880.

To all whom it may concern Be it known that I, GEORGE M. MORRIS, of the city of Gohoes, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyelet-Hole Attachments for Sewing-Machines, of which invention the following is a specification, reference being had to the accompanying drawings.

The general object of this invention is the production of an effective and durable attach-' ment which, when properly combined with a sewing-machine having an eye-pointed needle reciprocating'or vibrating in a constant position, shall, in connection with the sewing-ma- 1 chine, be capable of automatically binding the edge of an eyelet-hole all around with a series of over-edge stitches, and shall be readily adjustable to properly bind the edges of eyeletholes of different sizes, and with over-edge stitches of various lengths and at divers distances apart, or with different numbers of the over-edge stitches in the series surrounding the eyelet-holes. To that end I make this attachment with a work-moving feed-ring and 2 operating devices, which are adapted to be actuated by the driving mechanism of a sewing-machine, so asto automatically vibrate or reciprocate the circular feed-ring, or move it bodily to and fro, and also rotate the same 0 concentrically step by step, to form the overedge stitches and space them all around an eyelet-hole in the fabric moved by and with the feed-ring. I also make the operating devices of the work-moving feed-ring adjustable,

3 5 so that the over-edge stitches can be made at different distances from the center of rotation of the feed-ring to properly bind eyelet-holes of different sizes, and so that the feed-ring can be vibrated or moved to and fro bodily various 4.0 distances by the same operating devices to maketheover-edgestitchesofdifi'erentlengths, and so that by the same devices thefeed-ring can be rotated by steps of various lengths to cause different numbers of the over-edge stitches to 5 be made in one revolution of the feed-ring as shall be required to properly bind eyelet-holes of various sizes and in different fabrics. I also combine with the feed-ring a presser adapted to press the work into or upon the feed-ring, and made movable to and fro with and preferably by the latter, and pivoted to a sewing-machine presser-bar, and furnished with adjusting devices for regulating the position and extent of the vibrating movements of the presser.

In the aforesaid drawings, Figure l is a plan of one of my improved attachments. a part being broken out. Fig. 2 is a side elevation. of the same sectioned at the line 2 z in Fig. 1, and Fig. 3is a section of the same at the line y y in Figs. 1 and. 2.

Figs. 6 and 7 are plans of detached parts, and Fig.8 is a plan of a modified w rk-presser. Fig. 9 is a perspectiveview of a like attachment applied to a sewing-machine having a needle recipro- 7o catin g in one constant place. Fig. 1 is a plan, and Fig. 11 a section at the line 1) c in Fig. 10,

of a modified part of this invention. Fig. 12 shows an eyelet-hole bound by overedge stitches.

A is a circular feed-ring or annular disk-like plate, which is adapted to be revolved concentrically step by step, and to be moved to and fro in or nearly in the direction of its diameter, and to engage with the fabric V, in which the eyelet-hole is to be worked,'and to move the fabric to and fro and revolve it step by step closely over or upon a work-supporting plate, U, through a perforation, a, in which plate the needle of the sewing-machine recipro- 8 5 cates, and under which plate are the usual devices which co-operate with the needle in forming the stitches.

The fabric or material, V, to be worked is to be placed either under the feed-ring A, as ingo dicated in Fig. 11, or upon the feed-ring,.as represented in Fig. 3, and asI commonly prefer. The part of the feed-ring in contact with the fabric is rough or serrated, or furnished with pointed project-ions a, adapted to engage with 5 the fabric and secure the to-and-fro and stepby-step rotary movements of the fabric by and with the feed-ring when the latter shall be properly pressed upon the fabric on the needleplate U, as in Fig. 11, or the fabric shall be pressed upon or closely through the feed-ring on the needle-plate, as in Fig. 3, by the springactuated presser B, or by other suitable means.

To give the proper to-and-fro vibrating or reciprocating motion to the feed-ring A to cause the formation of the over-edge stitches, the feed-ring is journaled or fitted to turn concentrically in or upon and is carried by a vibrating or reciprocating part, 0. This feedring carrier 0 is mounted to move to and fro on a suitable support--as, for instance, in or on ways or guides b b on a plate or stock, D which is to be firmly secured to the bed or frame T of the sewing-machine, essentially as represented in Fig. 9.

With the feed-ring carrier 0 are combined suitable devices for imparting thereto from the driving mechanism of the sewing-machine the proper uniform intermittent vibrating or reciprocating movements necessary to cause the formation of the over-edge stitches in the fabric carried by the feed-ring. For this purpose the part 0 is shown in Fig. l secured by a self-adjusting pivot-connection, E, to a lever, F, that is pivoted at c to the stock D, and is connected by a link, G, to a lever, H, which is pivoted at one end, a, to the plate D, and has its other end adapted to engage with a suitable rotary grooved cam, or other suitable known part of the driving mechanism of the sewing-machine, in such manner that the feedring A shall be moved by the carrier 0 and levers F H in one direction a certain short distance just before one descent of the sewingmachine needle through the said feed-ring, and in the opposite direction the same distance just before the next like descent of the needle, and shall be held stationary while the needle shall be in the fabric carried by the feedring.

With the feed-ring and its carrier I combine any suitable known means for imparting to the feed-rin g proper step-by-step rotary motion to space the over-edge stitches. For this purpose the feed-ring preferably has onits periphery a series of ratchet-teeth, d, with which engages a pawl, I, mounted so that at and by each movement of the carrier 0 and feed-ring A together in one direction (indicated by the arrow u in Figs. 1 and 10) the pawl I will cause the feed-ring to turn a step, and so that at and by each movement of the carrier and feed-rin g in the opposite direction one or more of the teeth d of the feed-ring shall pass by the pawl I and cause the latter to engage with another tooth, and thus effect the rotation of the feed-ring by uniform steps.

By having the pawl I mounted on a fixed support in combination with the feed-ring A, the latter can be rotated in consequence of the to-and-fro movements of the feed-ring and its carrier 0, and by steps of suitable lengths for spacing the over-edge stitches around eyeletholes of certain large sizes.

To impart to the feed-ring B rotary motion by steps of suitable length for properly spacing the over-edge stitches around very small eyelet-holes, suitable means are provided for giving to the pawl I reciprocating or vibrating movements simultaneously with and in opposite directions to the vibrating or reciprocating movements of the feed-ring carrier. For this purpose the pawl I is carried by a mova ble part, J, which in Fig. 1 is jointed to a lever, K, having a fulcrum-stock, L, and connected by a link, M, to the lever F, to which the feed-rin g carrier 0 is connected.

The pawl-carrier J, in Fig. 1. is fitted to slide to and fro in a slot at e in the slide 0, as indicated in Figs. 1, 2, and 4.

Combined with the feed-ring carrier 0 and pawl-carrier J are suitable adjusting devices for altering the lengths of the to-and-fro movements of the pawl I, to change the lengths of the steps of the feed-ring A in its rotation, and thereby alter the spacing or numbers of the over-edge stitches around the eyelet-hole. For that purpose the lever K, in Fig. 1, has its fulcrum-stock L adjustable along that 1ever by being secured in a slot, f, in the lever, and between ways or guides g g on the bedplate D, and movable therein by a screw, N, engaging with the fulcrum-stock and journaled to turn without endwise movement in bearings h on the base-plate. I

As a means for giving, through the abovedescribed devices, different lengths of reciprocating and step-by-step rotary movements to the feed-ring A, to correspondingly alter the lengths of the over-edge stitches and the widths of the spaces between them without altering the vibrating movement of the driving-lever H, the link G is secured to the levers H and F by pivotstocks 43 j, that are adjustable along the slots Z in those levers.

For adjusting the center of the circle of the feed-ring A at proper and different distances from the point where theneedle reciprocates, as required for eyelet-holes of different sizes, the feed-ring carrier 0 is secured to the pivot-stock E of the lever F by a nut, m, and headed screw a, adjustable alonga slot, 0,in the feed-ring carrier. When this attachmentis in action the eyelet-hole work V is to be pressed upon the needle-plate U and feed-ring A, or the latter is to be pressed upon the work on the needle-plate by suitable means. I commonly prefer to have an annular presser, B, adapted to bear upon the work just within and upon the feed-ring, and to be moved to and fro with and by the latter.

In Figs. 1, 2, 3, and 9 the presser B has an arm, 19, with a vertical cylindrical socket, s, fitting and secured upon a pivot-stem, s, Fig. 3, attached to the lower end part of the usual presser-bar S of a sewing-machine, so that while the ring-presser B bears upon the eyelet-hole work or fabric V within or on the depressed inner portion of the feed-ring A, as indicated in Fig. 3, and the feed-ring is being turned step by step about its center, and also reciprocated by its carrier 0, the presser B shall be moved to and fro about its pivot-support S with and by the reciprocating feed-ring,

and at the same time the lower annular end part, t, of the presser, being smoothand small where it bears on the [fabric, will freely permit the latter to be turned step by step under the presser with and by the feed-ring.

The ring-like end part, 15, Fig. 3, of the presser can be free to be turned horizontally in a socket in the presser by contact with the fabric V as the latter shall be turned step by step by and with the feed-ring.

To control the position and limit the extent of the vibrating movements of the presser B on the presser-bar S in conformity with the various positions and different lengths of the to-and-fro movements of the work-carrier, I make the stock of the socket 8, Figs. 3 and 3, and the stock of the pivot-stem s with lugs R and Q Q and screws I? P, which latter can be turned and adjusted endwise in the lugs Q Q toward and from each other and the intervening lug B, so as to thereby limit the extent of and position of the vibrating movements of the presser. The pivot-stem s can be on the presser and the socket s on the presser-bar, and the screw-holding lugs Q Q can be fast on the stock of the socket and the intermediate lug, R, on the stock of the pivot-stem.

Fig. 8 shows a modified presser having the upper part of its shank q made flat and perforated transversely, so that it can be secured in a vertical slot at q, Fig. 3, in the presserbar S by a transverse pivot-screw, 'r, and thus allow the presser B, Fig. 8, to be vibrated thereon to and fro with and by the action of the work-feeding ring A, the foot t of the presser. being in that case supported by opposite horizontal pivots t t, Fig. 8, to make the foot bear evenly on the fabric in and upon the feed-ring in its to-and-fro movements.

In Fig. 5 the presser B is represented by dotted lines, and held by a spring-arm, 12, that is hinged at 17 upon and reciprocated by and with the feed-ring carrier 0, and furnished with an elevating-spring, p and depressing screw-clamp 19 for raising the part B high above the feed-ring to permit the insertion of the fabric, and for pressing the part B upon the feed-ring or the fabric thereon, thus dispensing with a presser mounted on the usual presser-bar 0f the sewing-machine.

By having the feed-ring A properly toothed or furnished with suitable points on its under surface an (1 extended somewhat below the carrier G and movable a little vertically therein, with the spring-presser B bearing on the feedring and the fabric V placed under the feedring and upon the smooth needle-plate U of the sewing-machine, substantially as indicated by dotted lines in Fig. 5, the fabric will in that case be reciprocated and rotated step by step by and with the feed-ring.

In Figs. 10 and 11 the feed-ring carrier 0 is pivoted to vibrate on an upright support, S, which is to be a part of or firmly secured to the usual vertically movable downwardlyspringing presser-bar of the sewing-machine, and the carrier J of the driving-pawl I is pivoted on the carrier 0 or its said support. The two carriers 0 and J are to be connected by adjustable links E M, Fig. 10, and a lever, F, or suitable known means with the driving mechanism of the sewing-machine, in such manner that the proper intermittent to-and-fro movement and step-by-step rotary motion shall be thereby imparted to the feed-ring A, to cause the forming and spacing of over-edge stitches of various lengths and difi'erent numbers around eyelet-holes in a fabric, V, which, as

shown in-Fig. 11, is in that case under the' feed-ring, and is thereby moved to and fro and rotated step by step on the needle-plate U of the sewing-machine.

I believe that prior to my invention sewingmachines for working eyelet-holes have been devised with a circularfeed-ring adapted to engage with the fabric to be worked, and formed with ratchet-teeth in and around its circumference, and rotated step by step in one constant position on the needle-plate by a reciprocating pawl engaging with the ratchetteeth of the feed-ring without any reciprocating or to-and-fro movement beingimparted to the circular feed-ring; and I do not claim that feature.

What I claim as my invention is- 1. The combination, with the circular feedring A, of means, substantially as described, for holding said feed-ring and moving it to and fro, and for rotating the same step by step, substantially as set forth.

2. The combination, with the circular feedring and means, substantially as specified, for holding thefeed-ring and moving it to and fro and rotating the same step by step, of adjusting devices, substantially as described, for altering the lengths of the steps imparted to the feed-ring in its rotary movements, substantially as set forth.

3. Thecombination,with thecarrierO,means for moving the same to and fro, and feed-ring A, journaled on the carrier, of actuatingdevices connecting said carrier and feedring, substantially as described, whereby rotary motion is imparted to the feed-ring by steps simultane ous with the movements of said carrier in one direction only of its to-and-froimotion, as set forth.

The combination,.with the feed-ring carrier G, movable to and fro, and feed-ring A, having theratchet-teeth d, and journaled on said carrier, of the pawl I, pawl-carrier J, lever-F, means for operating the latter, and devices, substantially as described, connecting said lever with the pawl-carrier and feed-ring carrier, substantially as set forth.
