Totali 11:71am it may concern:

Be it known that I, JEHU C. MOORE, of Madison, in the county of Jefferson and State of Indiana, have invented an Improved Tuck- Marlier for Sewingllaehines; and I do hereby declare that the followin g is ai'nll and exact parts improved construction of a tuck-marker, the

main partlot which is composed of a single wire or rod, bont so as to form two arms, be.- tween which the cloth passes to he sewed and marked for t'ncliii-ig, and in the arrangement ot the tuck-marker in combination with the presser foot or plate of a sewing-machine, bcng provided with a clamping or attaching device, by which it is secured to the arm thereof, a little above the presser-t`oott The drawing represents the tuck-marker as applied to a W'heeler \\`ilson sewing-machine; but it is readily adapted to other sewing-machines, and the principle oi' its .combi-l nation` with the presser-foot is the same in all sewing-machines. The wire which forms the body of the. instrument is bejnt so as to form two arms, A B, one heilig overand nearly parallel with the other, andata sutlicient distance from it to ati'ord room for the passage of the cloth between them. 'lhe lower arm A rests upon and along the clotlrplate C ot the scwingmachine, near one edge thereof; and in order to hold it iixedlyin its position a hook or clip, a, thereon catches under the edge of the cloth-plate, as shown. '.lhe upper arm is provided with elamp-platesfb c and a clampscrc\v,r1, or an equivalent device, by which to embrace the presser-arm D above the presserfoot f at such a point 4as to allow the lower arm A to rest ou thecloth-plate-preterably near the edge thereof-so that if the said plate is curved downward, as is common, the arm may lie partly or entirely below the general surface of the plate and offer no obstacle to the'eloth iu feeding it along.. The free ends g and h, respectively, ofthe two arms A B,

.are bent laterally, soas to occupy posit-ions parallel, or nearly so, with the direction of the feeding of the cloth, and at any distance from the needle -i ot4 the sewingmachine desired,

the upper arm B ofthe marker being capable ot sliding freely in its clamp-plates b e on'lo'osen-in g the clamp-screw d, so as to set the markers at the required distance to produce the requisite separation of the tucks. The lower arm has, or may have, a stationary markingedge, l., projecting upward a litt-le, subst-atb tially as represor-ned, while the uppexiarm has,

or may have, a- V-grooved roller, au, fitting over the lower marker I, as shown in lFig. 2; or, instead ot' a roller, astationary'notched marker may be used.

The attaclnnent of the tuck-marker to the presser foot or arm, besides the convenience and simplicity of the arrangement, has `the advantage otl causing the upper arm B, which presses down by its own elasticity, to rise with the presser-foot in feedin g along at each stitch,

so that the' upper marker m relieves the pressnre on the cloth just at the moment required,

and also the said varm B, with its marker m, lisv thereby lit'ted away from the cloth wheutho i presser-foot is raised for inserting and taking out-'the cloth. 'I

The hook a. prevents the lower arm A from rising when the upper arm is raised with the presser-foot.

WhatI claim as my invention, and desire I to secure by Letters latent, isf- The tuck-marker herein described,composed oi the two arms ,A B ot` an elastic bent wire or rod, and provided with a clamp for attachment to and adjustment on the presser'arm of l ,a sewing-machine', and with a hook, a, and

marker bearing projections g h, snbstantiall y as herein specified. -I
