Fig. 9 is a vertical parallel with the margins of the same, and is 'longitudinal section of the same on the line embraced throughout its length by a metal Ico 5o 9 9 of Fig. A. Fig. 10 isadetached plan View sheath C', which is of inverted-U form in of the gage-plate. Fig. l1 isa detached view, cross-section, as shown. The rear end of the creasing-bar C is bent, as at c, loosely around an attaching-screw D, the stem of which attaching-screw is inserted into an internallyscrew-threaded cavity or socket e, which is formed in the inner end of the connectingstud E. The stein of the screw D passes transversely through the rear end of the sleeve C', which latter is loosely interposed between the head of the screw D and the inner end of the stud E. The opposite or outer end portion e of the stud E is reduced in diameter and extends transversely through the upper end of the standard A2, asuitable head E heilig riveted or screwed upon the outer end of the reduced portion e. It will be obvious from this construction that the standard A2 is thus very firmly clamped between the shoulder left by reducing the portion e and the head E and that thereby a very strong and iirm connection is provided for the stud E, and also that a correspondinglyiirm attachment is provided for the creaserbar C, which in nowise interferes with the required operative movements thereof. At its front or opposite end c2 this creaser-bar, which is preferably a wire rod, is bent inwardly and downwardly at right angles, the outer extremity c2 of this portion c2 being bent upwardly in segmental form. This segv mental extremity c2 of the arm c2 of the creaser-bar C is caused to come intermittently downward toward the creasing-flange ct, and the under side of the segmental portion is formed with a longitudinal notch or groove c4, which is of inverted-V shape in cross-section and registers at the proper time with the said iiange a.

F designates the presser-foot proper and G the main-fraineof the attachment, these parts being formed integrally with each other, and the presser-foot being formed upon the inner corner of the front end of the main frame and extendingr forwardly therefrom, as shown. At its outer end the presser-foot F is formed with an integral upwardly-extending forkstandardjiat the upper end of which is formed an approximately horizontal fork F", which latter is adapted, when the attachment is in proper operative connection with the sewingmachine, to engage frictionally or otherwise a groove 7L in the lower end of the presserfoot bar II ofthe sewing-machine, said presserbar working vertically, in the usual manner, through the head H of the sewing-machine.

The main frame G extends over the tuckerplate A, and is secured thereto, so as to slide longitudinally thereof by means of a baseplate or shoe I, which lies directly beneath the tricher-plate A and which is connected to the main frame G by two screws t', which pass vertically through the inner part ot' the main frame and similarly through the subjacent part of the shoe I. The outer margin of the shoe I is turned upward, as at i', so as to come into contact with the corresponding outer margin of the tucker-plate, while the opposite margin 2 is turned or folded over upon the body portion of the shoe I and lies in contact with the corresponding margin of the tucker-plate, thus forming a guide or groove between the fold t2 and flange 'i' for said tucker-plate. At the outer corner of the t'rout end of the shoe I is formed an integral outwardly-projecting lugor extension I', from which rises au index arm or spur I2, which extends over the tricher-spring B, this arm or spur acting in conjunction with the graduated scale ofthe gage O,hereinafterdescribed. At the front end of the main frame G is formed an oblique extension G', the outer end of which is formed with a Vertical standard g. The base part of this extension is made of skeleton form and arranged obliquely, as shown, in order that a better View of the fabric may be had as it passes from the gage O. To the upper end of this standard gare pivotally secured the two outer members J and J of the ereaser-bar actuating-lever, a bolt or rivet K passing transversely through the standard and also similarly through the outer portion of the lever-sections J and J. The inner ends of these lever-sections are formed in their under sides with invertedU-shaped recesses j, which, when the lever is depressed, receive the creasing-bar C, so as to permit the lever to depress the said bar. The leversection J is formed at its outer portion with a vertically-elongated slot y2, while the lever member J is formed with an internally-screwthreaded eye J2. A screw j* extends trans- Versely through the slot l7'2 and eye j and serves to bind the two lever-sections J J adjustably together. The outer end J2 of the lever-section J is curved upwardly and out` wardly, so as to cross the path of movement of the screw m, which clam ps the needle M to the needle-bar M of the sewing-machine, the said needle working through an eye or hole j" in the pressenfoot F. It will thus be seen that each time the needle-bar M descends the screw m strikes the upwardly-curved end J2 and depresses the lever J J J2 in the manner of a cam and consequently ettects the depression of the creaser-bar C smoothly and in such manner as to cause its arm c2 to approach the creasing-flange a, and thus make a crease in the fabric between them, as will be readily understood. As the needle-bar M rises, a spring L elevates the creaser-bar, and this spring is secured at its outer end against the rear of the standard g, the corresponding or rear end of the bolt or rivet K extending through the outer end of the spring L. This spring is of somewhat spiral or Volute like form,so that its free end lies directly beneath the creaser-bar G and in contact with the under side of the sheath C thereof, constantly exerting an upward tendency.

In order to retain the tucker-plate A in any desired position or adjustment with respect to the main frame G and the underlying shoe I, a clamping-screw N is carried by the extension or lug I of the plate I, the lower end IOC of this screw impinging upon the outer edge of the zucker-plate and thus locking it in the desired position.

The tucker gage or plate O is shown as resting upon the er-plate A and main frame G and as having its body portion of suitablyelongated form, provided with a longitudinal slot o. A suitable graduated scale is formed upon the upper side of this gage-plate near its outer margin, the principal graduations of the scale being designated by numerals or in any other suitable manner. A clampingscrew P is carried by the main frame G and passes through the slot o thereof, and the lower end of this screw impinges upon the upper side of the tucker-plate, so as to retain the latter in any desired position of longi tudinal adjustment. The front end of the gage O is provided with a lateral and vertical extension o', which unites integrally said gage with a cross-bar O', said cross-bar being located beneath the plane of the gage, as shown in Fig. 11, and is provided at its free end with an upturned guide-flange o2. A slot or groove 03 is thus formed by the proximate margins of the extension o and flange o2, within which the tucker-plate rests, which contributes toward guiding said gage O as it is moved longitudinally for adjustment. It will be observed that the faces of the extensions o' and iiange o2 are vertical and in line, thereby affording a guide for the fabric as it passes to the needle M. v

`As a separate and further improvement, we direct attention to the c'onstruct-nn now to be described. Heretofore it has been impossible to prevent contact of the feed-plate with the tucker-plate in this class of attachments, particularly when the parts of the tuck creaser or marker have been adj usted to mark for narrow tucks, and much inconvenience and annoyance, as well as injury, have resulted from this defect. In order to prevent all possibility of such occurrences, we form or mill out the under side of the extension A of -the tncker-plate with a recess or cavity S, which milled-out portion overlies the feed-plate R, and into which the feed-plate rises as it reciprocates without ever coming into actual contact with the tucker-plate A. This will be more readily understood by reference to Figs. 13 and 14 and to the dotted lines in Figs. l and 14.

The general operation of the tuck marker or creaser is believed to be obvious from the above description,` and hence need not, it is believed, be stated in full here. It will be seen that the attachment is, as awhole, of superior strength, durability, and simplicity as compared with previous forms of attachments of this class; also that the pressure of the creasing-arm is readily variable to accord with different thicknesses of fabrics or when the tucker-plate is adjusted for marking wide tucks, in which latter event greater pressure will be imparted to the bar C by rst suitably adjusting the levers J J to give a greater throw; furthermore, that the lifting-spring for the creaser-bar is positive and direct in its action, and that there is no possibility of contact of the feed-plate of the sewing-machine with the J er-plate.

As a further improvement, we upset or raise that portion of the surface of the main frame G from which the part G extends, and which is lettered G2, above the surface of the presserfoot F and the plate G, whereby space is afforded beneath the part G2 and the extension G for the gage O to freely move within.

To further increase the capacity of the .tuck marker or creaser for marking narrow tucks, we cut away a portion of the presser-foot F, as shown clearly at f2, so that when said presser-foot is depressed said cut-away portion will come opposite to or register with the path of movement of the feeding device, whereby said feeding device may operate independently of and without touching the said presser-foot. It will, of course, be noticed that by providing this cut-away portion f2 we are enabled to move the extension A of the tucker-plate closer to the needle. Intermediate the vertical part o and the vertical lug o2 of the gage O is a transversely-extending notch or recess o3. It is within this recess that the tucker-plate is inserted, as will be manifest from an inspection of the drawings.

As a further improvement, we direct attention to the shape of the inverted-U-shaped recesses 7' in the lever-sections J J', each of said recesses being provided with a substantially-vertical extension or side wall j at the side adjacent to the pivotal connection of said levers, whereby the upward movement of the levers is limited. Said side walls j engage the adjacent side of the U-shaped covering C ofthe creaser-bar, and thus said lever is constantly maintained in proper position for its connection with the needle-bar of the machine. It will be manifest that to disconnect said levers J J from the creasingbar the operator will simply depress said creasing-bar slightly with one finger, when the said levers may be readily moved away from the creasing-bar.

We claim as our invention- 1. In a tuck marker or creaser, the combination of the tucker plate provided at one end with a standard and. at its other end with a tucker blade, and a creasing bar consisting of a wire rod`formed into a vertically disposed eye at on'e end for its attachment to the tucker plate standard, whereby it is free to pivot vertically but is held from rotary movement, and being bent downwardly at its other or free operative end to engage the creaser blade, a lever pivoted to the tucker plate and provided on its under side with a notch which ts over the creaser bar, said lever operating to depress the creaser bar when struck bythe needle bar of the machine, and a plate spring normally maintaining the, creaser bar at the upper limit of movement allowed it by the notched lever, substantially as described.
