tending part supporting an integral upturned standard member to which an operating'lever is pivotally attached. Overlying the laterally extending plate, just referred to, is .an adjustable gage plate superimposed on which is a transverse clamping plate attached by a set screw to the saidlaterally extending plate or at the junction of the said plate with said forwardly'extending part.

" The marking or creasing member consists of a spring sheet metal device in the form of a loop, the two parts of the said marking or creasing device being constructed near their free ends me. well knownmanner for creas- 1 lngor marking-a fabric. passing between them. The lower armor part of the said creasing or marking device is arranged to pass beneaththe said clamping plate so that .H. the latter serves to secure said creasing or" marking device and said gage plate in place. The operating lever, which is pivoted to the frame part above referred to, impinges against the upper arm of saidcreasing member and is lifted, after each downward stroke 77, Fig. 1. 7

Referring to the drawings, 12 denotes a presser foot having a shank 13 adapted for attachment to the presser bar of a sewing may be adjusted.

imparted thereto by a projection carried by tachment; Fig. 5 is a detail view of the gage plate; Fig. 6 is a detail bottom view of the clampingplate; Fig. 7 is a section on line machine. Formed integral with said presser foot, and extending laterally therefrom, is a plate 14 having at-its end an integral forwardly extending part 15 integral with which is an upwardly extending standard or arm 16 the end of whichis turned forward to form a lug 17 to whichthe operating lever 18 ispivoted; These integral parts 12, 13, 14, 15, 16 and 17, constitute theframe of theattachment. i Overlying' the said laterally extending plate 14: is a gage plate 19 superimposed on wh ch is a transverse clamping plate 20 whlch is secured to the frame by set screw 21.

The creasing member 22 is in theform of a sprlng sheet metal loop the lower and upper arms of which are constructed, respectively, w1th an upturned lug 22 was groove 23 registering with the said lug 22*. This cre asmg member'is of well-known construction and operates in theusual manner toform'a creaseon a layer of fabric passing over said lug and beneath said roove. The lower arm of this creasingmem er, which is of spring? sheet metal, underlies the said clamping plate 20, so that the latter serves to secure said creasing member as well as said gage plate in any positionsto which these parts r r so f The gage plate 19 is provided near one end with a forward extension 19 having upturned lugs 19 at its forward edge and which lugs embrace the lower arm or part of the creasing member; and the clamping plate 20 is provided with downturned lugs 20* which embrace said lower arm of said creasing member andjwhich also embrace said forwardly extending part, 15 of the frame of the at: tachment. V The upturned lugs 19 on the gageplate 19 serve as a guide for the folded edge of, the" fabric being stitched, the adjustment of the gage plate 19, on which said lugs are formed, determining the width ofthe tuck being formed. One of the lugs 19*. is "provided with a horizontal extension 19 which overlies and smoothes out orpresses down the folded fabric passing beneath it,

thus doing away with the smoothing out' 10E plates heretofore in use in some tuck-creaslng attachments.

The upward movements of the operating lever 18, under the influence of the spring 6 upper arm of the creasing member, are limitediby. a lug24 overlying the upper edge of said operating lever and'carlriedby a stop overlies said forwardly extending frame part and is embraced by said lugs, a clamping plate overlying said forwardly extending frame part, and also overlying the lower part of said creasing member and said gage latexa set =screw for said .clam in late plate 24 secured in place by a rivet 27'. passing.

' upward"movements of the upwardly springwanloper-ating' lever pivotedto saiddug and engaging the upper part of said creasmg member, and a stop member for limiting the ing' upper part of said creasing member.
