TUCK-MARKER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 293,(92, datedFebruary 5, 1854.

Application filed October 31,1853. (Modch) T0 ctZZ whom it may concern.-

Be it known that I, JosErn S. SACKETT, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Tuck-Markers for Sewing-M2 chines; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, .and represent, in

Figure 1, a perspective view; Fig. 2, atransverse section through the body of the presserfoot on line 00 w of Fig. 3; Fig. 3, an under side View, looking up; Fig. 4, an end view from the right; Fig. 5, an end view from the 1eft,'show-- ing the creasing finger and rib; Fig. 6, a vertitical section through the creasing finger'and rib; Fig. 7, the guide f detached, showing its connection with the horseshoe-shaped spring.

This invention relates to an improvement in devices for attachment to sewing-machinesto mark the line of one tuck. while another is being stitched. This marking is usually produced by a vertical rib underneath the fabric in which the tuck is to be made, and a finger above in such connection with the needle arm that the descent of the needle will bear the finger upon the upper side of the fabric and press it down upon the rib, so as to indent the fabric at each descent .of the needle, this finger and rib being arranged distant from the needle according to the width 9f the tuck, the crease thus formed by the finger and rib being the edge'of the fold for the tuck.

The object of my invention is to simplify the construction of the marker, and also to give to the marking mechanism a rubbing effect, which will producea better crease than simply by pressure, as in the more general constructions; and the invention consists in the construction as hereinafter described, and

' more particularly recited in the claims.

A represents the socket for attaching the device to the presser-foot spindle, the socket extending downward and turned forward to form the presser-foot 13. Through the vertical portion of the presser-foot a horizontal bar, 0, is arranged to slide at right angles to the line of stitches to be made. On this bar is a lever, D, which extends forward. It is ar- 1 ranged in a notch, E, in the body of the press er-foot, so as to retain its position, but yet so as to swing vertically up and down. The bar 0 is made fiat upon one side, as seen in Fig,

the lever D and turn it downward, as indi-- cated in broken lines, Fig. 2.. Then,as the needle-bar ascends, a spring-F, in connection with the lever, will cause it to return. Th1s spring F is attached to the head of the lever,

and so as to bear upon the base G.

At one end, H, of the bar G an arm, I, is

hung. This arm, extending forward and then turned at right angles, extends parallel with Y the bar 0 in front of the presser-foot to about the length of the bar 0, and at that end it turns toward the bar 0, where its extreme end forms the creasing-rib a. On the other end of the bar 0 the creasing-finger b is fixed. This creasing-finger is of inverted-V shape upon its under side, and extends from the bar O, presenting a cam-like surfaee-tha't is, a surface eccentric to the bar 0. The rocking movement of the barO brings the finger 1) onto the rib a, and because of its eccentricity the finger is drawn along the surface of the rib, as indicated in broken lines, Fig. 5. The eccen' tricity of the working-surface of the finger is so slight that the parts readily yield to permit the rubbing operation. The arm ll lies upon the woi-kplate, and the fabric to be creased is passed over the rib a, and beneath the'finger 1); hence at each depression of the lever D the finger b presses the fabric onto the rib a, and rubbing upon the fabric produces a crease therein. The lever D ismade fastto the bar 0 by a setscrew, d, or an equivalent therefor, and so that by loosening the screw cl the bar 0 may be moved to the right or left, and

such movement of the bar 0 carries the arm I to present the rib a and finger b at the proper next tuck is to be made.

distance from the path of the needle to crease the fabric in the line where the fold for the As a guide for the edge of the tuck being stitched, I extend the base Gforward andto the right, and in this extension make a slot, e, parallel with the bar G. This extension is raised above the bottom of the presser-foot, as seen in Fig. 4C, and so as to stand above the bar I.

In the slot 0 a slide, f, is arranged. This slide embraces the arm I, so as to form a partial support for the arm, and is movable freely beneath the extension of the base. The slide is attached to a horseshoe-shaped spring, L, its open ends extending through the slot e one end in connection with the .slide f, the other free. The spring is compressed to pass intothe slot e. Then its reaction binds in the slot sufiiciently to hold the guide in any position to which it may be set.
