UNITED STATES PATENT OEEIcE.

HENRY W. FULLER, OF BROOKLYN,

AND ANTHONY W. GOODELL.

NEW Youn, AssicNoR. To H'rMsETr Specification forming part of Letters Patent No. 28,633, dated ,lune-.51, 1860.

chilies, which I denominate the Universal Marker for Plaiting andluekingf" and I dos hereby declare that the following is a full', clear', and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, wherein- Figure l is aside elevation, showing my apparatus, also the needle-arm and pressure-foot of a sewing-machine; and Fig. 2 is a plan of the same with the arms removed to show the other parts. v

Similar marks of reference denote the same parts.V

The nature of' my said invention. consists in a vibrating marking instrument or instruments that move in unison with the needle, so as to crease or mark the cloth at a given distance or distances from the needle, and the same :not pressing onthecloth, except Awhile the needle is in the cloth, prevents such markinginstrument obstructing the cloth in its movement by the feed, and hence said mark can be iliade at any distance from the sewing and the cloth remain smooth. By the useof apoint vibrating in unison with the'needl'e and acting on the upper surface of the cloth, in connection with a notch or an elasticsurface or pad below the cloth, a crea-sc will be made whosedridge is below the cloth, and by the use of a point below the cloth and avibrating notch or elastic pad above a crease will be formed whose ridge is on .the upper lside ofthe. cloth, and by the use of one, two, or more of these up or down markers, or one up and down marker, the crease or ridge can be made exactly at the desired distance from 'the'liue of sewing, and either upward or downward, according to the way in which thecloth is to be folded over for the after operations; and on performing another line of sewing'the crease or creases are made for the next fold. This device is especially useful in all-kinds of tucking, and in plaiting shirt-besoins and similar work. By the useA of a vibrating pencil or chalk a line oi.' marks isinade by whieha second line of stitching is guided, the saine being useful in quilting or performing any straight or curved parallel lines ot stitching. It will be evident that if the marking-points are at right angles to the feed from thc needle the sewing and parallel thereto, regardless ot' the curved or zigzag form in which the sewing is performed.

In thc drawings, a represents the bed ot' any sewing-machine. bis the pressure-foot, and c the needle bar or arm, all of which may be of any form; and the sewing is to be performed by the needle (l, in connection with a shuttle looperer any device..

c is an arm extending from the needle arm or bar and vibrating with the same.

f is a pencil, chalk, or point adiustedfzgn said arm e, so that in its vibrations th point shall press upon theeloth, and consequently make a mark thereon at the distance from and parallel to the line of sewing being performed at This is specially ing or stitching.

g is a bar that may be at adapted to inarkin g for quiltsprings, taking the arm c, so as to yield in case interfere with the full stroke of tl 1e needle-ba r.

Z is a plate screwed onto the bed a and earrying the adjustable point m and leather n o-r its. equivalent. The point mais 'formed some'- rounded, and blunt chisel forms, so as not to injurek or catch in the cloth, and this point on needle; or several oftheselmints may be formed or .attached permanently on a plate at short distances apart. rlhe leather n is also represented as adjustable, andforms a. crease, i nto marking must'be a given distance from the which the second row of sewing is to be made.

x' taehefd to the press-- ure-foot, so as to lbe raised up with it, or may' so that the parts z' and k are raised from the 'j surface ofthe cloth, except when acted onby the arm e, and said arms 71, are also ittcd with of inequality in thethickness of cloth, and not what similar to the point '5, both being thin,

may be fitted to slide in a groove lor adj usting the same to the desired dist ance from theA ward crease and the parts 'lc-m an -upward' crease when theA cloth is exposed to the action of these parts by passing between the same; and in order to give motion to these markers the bar or arm e strikes on the spring part of the arms h h, (see Fig. 3,) pressing the surfaces together and crimping or creasing the cloth.

The drawings represent my apparatus as adapted for stitching three-ply shirt-bosoms,

Y as seen in Fig. 5, in which instance the plait folded under the cloth runs against the end of the plate Z as a guide, and the adjustable spring-ringer o, pressing on the plait, keeps it folded down tightly, ready to pass under the 4 pressure-foot 1)'. y

p is a swinging guide attached by the screw l to the arm carrying the bar g, and acted on by the spring 2Ito keep the end of the guide within the plait and the back of the plait Y against the end of theplait Z, so that the stitching will be upon the edge of the plaitwithun- A er1-ing certainty. For tucking, the markers .A should. extendaomeitherr sideof. the needlearm, and for this .purpose the bar g can be iitted in any convenient manner; but wherev a hold'er on `arm to the pressure-foot is usedin the manner shown the hole into which said bar sets may pass through the same and be y provided with a clamping-screw, so that said bar g can be inserted from the other side, and the plate l also stand on'fthe other side-of the needle, a second slot, 3, being 'provided for Vthis purpose. The arm e alsorequires tobe changed to the other side, in order to take the marking-points z' 11,. I"

It will be evident that the marking notch or point 'i or k, or both, might be placed directly on the arm ,e and lprovided with a suitable spring betmeenthe bar andpoint.` The 'Inansimultaneous with the-line of sewing, as set forth.

ner of attaching the parts to the sewing-machine must also be varied, as circumstances may require, for different characters of sewingmachines, or for divierent kinds of work to be performed; and the vibrating motion may be given to the markers by any other device besides the needle-bar.

I do not claim a. gage for spacing od' the width Nof folds, tucks, or plaits, either in a sewing-machine' or applied as a separate ap-` paratus for said purpose; but all the previous devices with 'which I am acquainted acted simply to perforate the goods or form a mark at a given point, to whichv the goods had to be foldedl by hand, Whereas my apparatus makes a complete crease in the cloth, so that the parts of the cloth, when laidrover each other, fold down yat these creases without requiring creasing by hand as a separate and prerequisite operation. p

What I claim, and desirel to secure by Letters Patent, isi y 1. Forming one, two, or' moref creases in cloth by means of markers on opposite sides of the cloth, one of which is connected with the bed of the machine and the other operates simultaneously with vibrationsof the nee'- l d le in a sewing-machine, whereby the crease 0r creases are 'formed in the-cloth itself parallel to the line of sewing in such a manner that the cloth is ready for doubling over at said creasesfor thenextline of sewing, as set forth. y

2. Marking a line on the surface of cloth or other material being sewed in a machine by means of .a .pencil or similar article that is pressed upon the surface of: said cloth at the time the needle perforates the. same and is raised therefrolnwhen the feed takes place, so as to produceV a series of marks parallel to and` In witness whereof I have hereunto set my lsignature this 25th day. of February, 1860.
