T aZZ whom it nuty con/perm:

Be it known that we, JULIUs O. GoonwiN and CHARLES W. WARREN, both of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in. Tuck-Markers for Sewing-Machines, of which the following is a specification.

In the accompanying drawings, Figure l is a perspective view of our improved device,

Fig. 2, a detail front elevation, showing part of a bed-plate of a sewing-machine; Fig. 3,

an end View, partly in section; and Fig. 4, a

detail view of the sliding wedge for adj usting the creaser-bar.

The crease-ulnar Ais mounted directly upon the presser-foot B of the sewing-machine, which, for convenience of attachment of the ereaser-bar, is provided witha lateral extension, 21. The bar is secured upon the presserfoot bya headed button, I), which travels in a slot, a, in the bar. A screw-bolt, which is secured to the extension of the resser-foot, also projects up through the slot a, and is provided with a clamp-nut, a", by which the creaser-bar may be adjusted cndwise and held in any desired position.

The bottom plate of the marker 0 is provided with the ordinary smoothing-finger, D,

gage E, and thumb-bolt F, by which it is secured to the bed-plate of the machine. One end of the creaser-bar is formed with a suitablecreasing-notch or markeiywhile the opposite end is formed with a transverse slot out 3 5 in each side, in which upright guide-plates g,

carried on the bottom plate. work. It will be perceived that the creaser-arm moves vertically bodily with the resser-foot, and that the uprights g serve as means forloosely con- 40 necting the bottom plate and creaser-bar, and also as guides for keeping the parts in proper position in the adjustment of the bar and bedlate. p It is desirable to afford some vertical adjustment of the creasing end of the bar A in order to accommodate itto fabrics of varying thickness. This we accomplish by means of a sliding slotted wedge-plate, H, which works between the lateral extension of the presserfoot and the under side of the creaser-bar, and is provided with a couple of upright lugs or ears, h, which embrace the sides of the creaser-bar and facilitate its movement in adjusting. The screw-bolt on which the thumbnut atworks also passes through the slot in the wedge-plate. It is obvious that by sliding this wedge in or out the creasing end of the bar may be elevated or depressed. There is of course sufficient play of the uprights g in the slots in the sides of the crcaser-bar to per- 6o mit this rocking of the bar.

We find that where the creaser-bar is mounted on the presser-foot it is desirable for some reasons to impart a greater amplitude of vertical movement to the presser-i'oot. To 210- complish this by forming a heel or projection,

i. on the bottom of the prcsser-foot. The clothfeed is, rising against this heel, lifts the presserfoot higher than it .otherwise would. This increased motion of the presser-foot adapts the marker more readily to varying thicknesses of material.

We are aware that a crcascrbar mounted on a presser-foot, so as to move bodily therewith, and so as to be adjusted both vertically and 7s endwise, or longitudinally, is old.

We are also aware that a spring creaser-arm secured on the bottom plate ofa tucker-marker has been adjusted to obtain variations of pressure of the marking devices by means of a slotted sliding block working against an incline on the bottom plate. XVe make no claim, therefore, to suchsubjects-matter.

We hereby disclaim any subject-matter herein shown which is claimed in our application 8 5 No. 109,827, filed October 23, 1883.

We claim as our invention- 1. The combination, substantially as set forth, of the presser foot, the creaser bar mounted thereon, so as to move bodily vertio cally with the presser-foot, the bottom plate, and a loose connection between the bottom plate and a crcaser-bar, which permits the vertical movement of the latter. I

2. The combination, substantially as set 5 forth, of the presser foot, the creaser -bar mounted thereon and moving bodily therewith, the bottom plate, and the vertical guide on the bottom plate in which the creaser-bar works vertically.

5 3. The combination, substantially as set forth, of the presser-foot, the slotted creaserbar mounted thereon, the Wedge-plate which works between the creaser-bar and the presserfoot, and the clamping bolt or nut which serves 10 to clamp the presser-foot, wedge, and bar together. l

4. The combination, substantially as set forth, of the presser-foot, the slotted creaserbar mounted thereon, the sliding wedge-plate,

I 5 the clamping bolt or nut, the bottom plate,
