To all whom -it may concern:

Be it. known that; l, JOHANN .Muon KNneirr, a eitizen of the (,onfederationot Switzerland, and inside-nt'I of 1Q Ulmenstrasse, '(hemnit-z, in the Kingdom o't' bnxony, German lthnpire, have invented eertain new und useful Iniprovements in Ilm broidering-Maehines, oiL which the following a Spee-intuition. This invention relatesl to marflnneeI for embroidering eloth and the like, in whieh a suitable length of thread is embroidered in the cloth.' l

The ibjeetA of lthe'present: invention is to avoid the employment ot' the usual earriaeje for ,the tl'iread grippers by meanl o't' whirh the threads were drawn through the cloth.

Aeording to the present invention the coi'isiderable travel4 of the longitud braviI carriage is avoided and a d irert. and 'unilfoim tensionof the needle tln'eatl is Sreured. This .resultis obtained by first. transmitting tothe thread grippera short motion at right angles to lthe `cloth or the like to be embroidered and then rotating the Said gripper about an axis at right: angles to the thread and parallel to, the cloth.v

1t is advisable lto support. the gripper on a suitable Carriage reciprocating'within a. rotatable hollow niei'nber 'provided with an opening `through which the gripper is adapt'- eci rte 'move XVith this arrangement the gripper first seizes the thread and then d rawv the saine within the hollow rotatable member. 'lh'is member then rotutee so that thtl thread is wound a-.i'oum'l the exterior oi' ,the Said -ho'llew member. At. the end ol" the ro tation 4of the hollow member the thi-radis completely drawn through the material and the hollow member then rot atm` harltward to lits original position. l'n this position the gripper moves outward.t1oward the eloth and DttSses the thread again through Ihe rloth. The tghiead so passed through the cloth. is

Y' taken yu p-,byat vsimilardeviee arranged on the other side of the cloth and the profanel de scribed above is Irepented.

The invention `iS illustrated in the arrom- .pany ing.drawjngs, in which Figures v1 `to 3 re sent cross sections through `the I ieedle .nji'oi4 nr device aeeording .tothe present. invention, Fig. il representing .the ,first stage in 4the operation, in which tht` needle is seized by the gripper on vthe rigrht hand; Eig. 2 representing the eeeond stage in which the gripper haisl been withdrawn wit-hin the rotatable member; Fig'. 3, repre senting the third stage in which the thread has been drawn through the material after a partial revolution ot the rotatable ineinbei. l

ln carrying the invention into eti'eet aecording; to the forni shown in the dra-wings two hollow eylindrif'al membersI or drums aare rotatably mounted on each side of the' cloth imlieated by s s. 1`)i ame trieally Within said drums there are supported guides Z1,

but so as to be capable of being' drawn wit-li- Y l in the hollow member as shown in Fig'. 2.

The embroidery thread to be 4drawn' through theeleth .s' is ind ieated'bjI ,the line in yFie'. l as hanging4 looselyy in a loop on, the leftliand side of the cloth. hand lgripper r/ then Seinen the needle f prof' jeeting through the cloth and by means of the pinion l1. the carriage is moved into the position shown In ltnr. 2. ln this position.

thread within the hollowmember u. hollow member u new rotates in the direction oi the arrow :rin Fig. .3, whereby the' The' needle f is rari-ivd around with thogrrippei" r/f i and thel `thread l5 caused to lie around the rijlintlrittal Sl'n'fiue o1 the hollowI member u. ln this way an even tenslon on the thread 1S secured. When the -limitot" the motion has been rearhed. the hollow member n u ain returns in the direetion opponito to the ar- "row r to the .initial position hewn -in Fig. .Z.' 'lhe pinion z. then rotatee so that theea-rriel w is: moved into the position `Shown in Figc. l in whieh the needle j' is passed through the ('loth s to be `gripped by 4the opposite ta-rlier and `gripinir f/ on..t.he leftihand side of the cloth. The mechanism 'on the lei'thand side of the cloth then operates in the manner described with reference to the righthand mechanism. With thin devine itV will be .eeen that the draw on thethread is always uniform.

Aeach of said I claim 1. In a machine for `embroideringv cloth and the like, the combination with a needle, of a needle gripper, means for moving said gripper at substantially right angles to the cloth so as to draw said needle through the cloth, and means for rotating said gripper about a fixed axis at right angles to the movement of said needle.

2. In a machine for' embroidering cloth and the like, the combination with a needle, of a needle gripper capable of reciprocation at substantially right angles to the cloth 4so as to draw saidneedle through the cloth, a guide for said gri per and means for rotatmgsaid gripper a ,ont a fixed axis at' right angles to the movement of said needle.

3. In a machine for embroidering cloth and the like, the combination with a needle,A of a needle gripv er arranged on either side of the ycloth eacli capable ofA reciprocaiion at substantially right angles to the cloth, means for movin the needle ripper, so as to draw said need e through 51e clot-h, guides for rip ers, and means for rotating said gui es 'a out .a fixed axis at right angles-to the movements of said needle.

4. Ina machine for embroidering cloth and the like, the combination with a threaded needle, of a needle gri per, means :ter moving saidri per at su st-antiall righ't angles to the c ot so as to draw sai needle through the cloth, means for rotating' said gripper about a fix-ed axis at right angles to, the movement of said needle, and means rotating about said axis for drawingl said thread.

5. In a machine for embroidering cloth and the like, a hollow member capable of oscillatory 'rot-ationand havinan opening therein, a needle 'gripper slida 1y mounted within said hollow member, and means for and the like, a hollow drum capable of osl cillatory rotation and having al1-opening therein, a needle gripper,a carrier for said yripper slidably mounted within said holL ow drum, and means for vmovin said carrier4ubstantially at right ang es to the cloth so as to move said gripper through said opening.

In a machine for embroidering cloth and the like, a hollow drum capable of oscillatory rotation and having an'opening therein, a needle gripper, a guide diametri# cally arranged within said hollow drum, a carrier slidable on saidl guide, means for moving said carrier-on said nide, and a needle' ripper mounted o-n sai carrier and adapter?, on the motion of said carrier, to pass through the opening.

8. In a machine for embroidering cloth i and the like, the combination'with a needle,

,of a needle gripper adapted to reyolve about a fixed a'xis arranged :1t-substantially right angles to the direction of. movement of said needle, and means for opening and closing 'said grippers. 9. In a machine for'embroidering cloth and the like, the combination with a threaded needle, ofa gripper adapted to revolve about a fixed axis arranged at substantiallyright angles to the direction of movement. of said needle, means for opening and closing said grippers and means rotating about said axis for su porting said thread.
