IMPROVEMENT-IN RUFFLING ATTACH ENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 137,003, dated March 18, 1873.

To all whom it may concern.-

Be it known that I, THOMAS S. HUNTING= TON, of Baltimore, county of Baltimore, Ma ryland, formerly of the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in the Sewing-Machine Attachment for Fulling, Plaiting, Ruffling, and Gathering, for which I made application for United States Letters Patent on or about June 16, 1870.

The following is a specification of my said improvements, the purpose of whichis to give to my above-named attachment the capacity of acting automatically on three (3) strips, pieces, or thicknesses of cloth or other material, in such manner that the middle piece shall be ruffled or gathered while the top and bottom pieces are kept plain and smooth to form a belt, support, or margin for the ruffled or gathered piece, and the three pieces sewed together all at one operation.

My improvements consist in the employment of a hinged-feeder, h, in place of the spring-feeder described in my aforesaid application, in connection with a stationary adjustable guard, ashereinafter described, and

. view of the improved attachment; Fig. 2, a

plan of the feed-barf, hinged-feeder h, and spring k Fig. 3, a perspective view of the upright part a. of plate a and of the guard s which is attached thereto; Fig. 4, a plan of the guard s and upright part a of plate a; Fig. 5, a section of the feed-bar f on the line to w of Fig. 2; Fig. 6, a section of the feed-bar f on the line 3 z of Fig. 2.

a is a plate to which the several parts of the device are attached. I) is a jointed lever, one end of which abuts against the adjustable stud c which is attached directly to plate a, the other end of lever I) being in contact with stud d which projects up from feed-bar f, the longer leg of which bar slides between the guide 9 and the upright part a of plate a, the shorter leg projecting through a slot in the same part of plate a, as shown. t is a spring,

one end of which is attached to plate a at j, and the other end to the feed-bar fat k. m is a bar attached by a hinge or other flexible joint to an upright m. The bar 112- is slotted at n for the passage of the sewing-machine needle. h is the feeder. It is formed of two parts united at h Fig. 2, by a hinge to enable it to adjust itself with facility to variations in the thickness of the goods to be ruffled or gathered. h is a spring bearing on the back of feeder h. Both the feeder h and the spring h are adjustable, being attached to the shorter leg of the feed-bar j by a screw through slots, as shown. 8, Figs. 1, 3, and 4, is a peculiarly formed plate which I denominate a guard. It is stationary, being rigidly attached to the upright part of plate a, as shown in Fig. 3, so as to be adjustable to suit the thickness of the goods to be sewed. Its office is to protect the lowermost strip or thickness of goods passing through the device against pressure from the feeder h as the goods to be ruflied or gathered and sewed are advanced by the feed motion of the sewing-machine. The guard sis forked I or recessed as shown, so that it shall be clear of all connection with or bearing on the feeddog of the sewing-machine, while at the same time its two prongs shall completely guard the lowermost piece of goods from contact with the hinged feeder h. 4

In my device, the strip to be ruffled or gathered always passes between the hinged feeder h and the guard s; and in opera-ting the devicewhen three pieces or thicknesses are intended to be sewed together so that there shall be a ruffle attached to a belt, one

strip is caused to pass under the guard s, another between the guard and hinged feeder h, and the third strip-piece or thickness over said feeder, all passing at the same time under the presser-foot of the sewing-machine. If the bottom one of the said three pieces is omitted the middle piece is ruffled or gathered and sewed to the top piece, which remains plain. And if the top one of the three is omitted, leaving the middle and bottom pieces, the middle piece is ruffled or gathered and sewed to the bottom piece, which remains plain.

I claim- 1. The guard s in combination with the reciprocetinghinged feeder h, springh and feedsul stantially as set forth, for the purpose barf, all constructed and arranged on the supspecified.
