GOMPANY, on onrcnso, ILLINOIS, A conronnrron or ILLINOIS' ,sse'mme FOR SEWING-MACHINES. i

To all whom may concern:

Be it known that I, JosnrH'BnRcE n, Jr.,

a'citizen of the UnitedfStates, residing at Utica, in-the county-'jof Oneida, State of New York, have invented certain new and useful Improvements in ,Presser-Feet for Sewing-Machines, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in a presser foot for sewing machines, and more partlcularly to a presser ,with means for positively insuring that the edge of the upper portions of the fabricsections shall lie within the limits of the stitching mechanism;

A further object of the invention is to provide a presser foot of the above character with a portion thereof in -front-of the needle opening projecting below the remainder of thejsurface of the presser foot and adapted to co'iip'erate with the depressinn in the .throat plate '"for guiding the fabric section having the lower overlapped portion in a plane below the fabric section having the upper overlapped position. so as tofacilitate the overlapping of the fabric sections. 2' I 1 A still further object of the invention is to provide a presser foot-of the above char acter with a main section and'ian auxiliary yielding section arranged side loy side and adapted to engage, respectively,- the fabric sections whichare to be united, and also to provide said main section with a yielding part located wholly in frontzof the needle opening in the presser foot.

'lie/ i vhblly within-the limits of the stitching mechanism so that it will be fully facilitating the overlapping of the sections.

The presser; foot also has a yielding section in the main section of the foot located in advance of the needle opening which cooperates in guiding the material when passmg over cross seams.

Referring more in detail to the drawings:.

The improved presser foot consists of a supporting shank 1 which is adapted to be attached to the presser bar 9.. The foot portion of the presser foot is formed into .two sections, a main section 3 which is rigidly connected with the shank 1 and an auxiliary section 1 which is yieldingly connected thereto. Said shank l is provided with spaced

lugs

5 and 6 between which the shank 7 of the auxiliary section -LL slides. The cap plate 8 holds the shank 7 of the auxiliary presser foot in place. A spring 9 carriedby the shank 1 rests in a groove 10 in the upper end of the shank 7 of the aux- "iliary section of the presser foot and normally forces said section downwardly. Said shank'7 is formed with-a vertical slot 11 through which a pin 12 extendsfor limiting the downward movement of the auxiliary section 4. The sections of, the presser foot are cut-awayor separated so as to form a slot 18 which is adapted to receive the up- 7 turned edges of the fabric sections two fabric ections, indicated at F and F, respecti v The edge portions are turned up, as indieated at f and f, and these upturned-edges are directed into the slot 13. Mounted on the pressor foot is a fixed trim- In F igyf, the drawings, I have shown ming blade 14. Cooperating with this fixed trimming blade is a movable trimming blade 15. This forms a horizontal trimming mechanism which trims the up-turued edges.

The main section 8 of the presser foot is formed with'an opening 16 for the needles of the stitching mechanism. The throat plate; 17 has a depressed section 18, and the auxiliary section 4 of the presser foot has a portion 19 which extends below the lower face of the section 4 and into this depressed 1 \\'llll( the tabrlc guide. 21 is carried by the the up-turncd edges of the, fabric sections into said slot. The depressed section 18 terminates ust In front of the needles, as is clearly-shown 'in Fig. 6 of the drawings.

As the fabric sections leave the trimming portion 7' after it is trimmed is'crowded down underneath the fabric portionff which is held raised by the rib 20.' The "edge portion 7" passes over this guiding member -21. The main section 3 of the presser foot has a laterally projecting fabric guide 22 which extends into the slot 13, and the front curved edge of this fabric guiding member turns down the edge portion f 'onto the turned down portion f. The auxiliary section 4' has a vertically extending part 2st which fits in a cut-away section 25 of the main presser foot section and forms .a part of the wall of the needle opening. This part 21 is of suflicient height so as to extend above the lower 'face of the main section of the presser ,foot even 'when the aux-- iliary section is depressed to its full extent. The part 2% serves to keep the edge of the fabric portion f well within the limits of i the stitching mechanism.

From the above, it will be apparent that my improved p'ressor foot is constructed so as to positively turn down one of the upturned trimmed edge portions, and then turn down the other trimmed edge portion onto the first-named edge portion so that when the edge portions are brought back into the plane of their respective fabric sections they are overlapped. and this occurs litfOd'O they cross the needle opening in the presser foot. The main section 3 of the presser foot is formed with a viclding sec tion This yielding section 25 is carried b v a post 27 attached to a. spring 28 which forces said yielding section 25 down\ \'ardl v lo a limited extent. This yielding section 25 terminates just in rear of the trimming rmechanism. and the purpose of said yielding section is to engage a fabric section lIleflOllt of the needles when the main sec-tionof the press-er foot is raised by a cross seaii'lpassing underneath the same.- This insures that the fabric sections will be properly held and directed to the trimming mechanism when cross wants are passing umha-neath. the presser foot. i It will be noted that-the fabricguide 22 is carried by the sect ion 3 of the presser foot section land that these sections yield relative lo eat-h other. If two thicknesses of fabric pass under the main sectionfi or a cross seam passes underneathithis section, it will rise, while the section t, being indepemlently mounted, will remain on the single ihiclmess'of fabric and this results in separating the guides 21 and-22 120 permit the extra thicknem of fabric to pass through the guide passage formed by these guides 21 and i2 without-,in any waychoking-or clogging the passage. in othenwords, I have in substance, a guide channel which varies in width as the thicknesses in the fabric sections passing underneath the main foot vary.

It is obvious that minor changes in the details of construction and the arrangement 'of parts may be made without departing from the spirit of this invention as set forth in the appended claims.
