It will be helpful to the proper understanding ofmy invention to first consider some of the more important aspects and features thereof, so that these may be kept in mind during the subsequent reading of the detailed description of the practical and illustrative embodiments of my improvements-as shown in the accompanying drawings. Accordingly it is pointed out that the novel means or nose piece is an extremely vital part of a trimming machine without which the clipping mechanism cannot eiciently perform its trimming operation. In the drawings and description, only those parts of a standard or conventional clipper mechanism necessary to a complete understanding of the invention have been set forth; further information, as to the construction and operation of elements and details of a clipping machine not herein specified, but which are usual and wellknown, may be had from F. Y. Kitzmiller Patent No. 2,113,112, issued April 5, 1938, and the disclosure of the Thread Clipping Machine illustrated and described therein.

The thread directing, arranging, collecting and positioning means and the nose piece which einbodies such means in the various forms illustrated provides for the raising of the loose ends of any threads resting on or embedded in the textile material over which the clipping machine is moved. It does this by directing and arranging the loose ends of threads in line with the movement of the trimming machine and at the same time gradually raising these loose ends of the threads from the textile material. By the time the loose ends of the` threads thus reach the clipping mechanism, they enter between the cutting elements or teeth in a substantially vertical or erect position and project above the cutting edges thereof to be squarely cut oi thereby.

While the above takes place, the textile material-overwhich the clipping machinne is moved, is held down dat so that the textile material proper will not be raised by the suction created ahead of the clipping mechanism and for this reason cannot be drawn between the cutting teeth and damaged thereby. Furthermore, by causing the loose ends of the threads to be gradually raised to a substantially vertical position ahead of the cutting elements, the threads are cut off squarely by the cutting teeth as soon as they enter therebetween. The cut off ends are thus left in a position where they can be freely drawn away from the cutting teeth by the suction created ahead and above the cutting elements. This insures a quick and easy removal of the loose ends of the threads and prevents any clogging of the clipping mechanism by the cut olf ends of the threads. f

In the forms illustrated in the various figures of the drawings, my invention generally comprises an interchangeable device or nose piece A which performs the directing, arranging, collecting and positioning function of my invention. This nose piece is secured to the suction nozzle B at the inlet C thereof, while the cutting mechanism D in the form illustrated is located on the nozzle adjacent the inlet opposite to the nose piece. In this way the ends of threads projecting from or embedded in the textile material, over which the nozzle is moved, are directed, arranged, collected and positioned by the nose piece and properly fed to the cutting mechanism, cut olf thereby and removed by the air current produced by the suction in the nozzle as will hereinafter be apparent from the detailed description of the invention.

The suction nozzle B is made up of the housing l which has suitably attached thereto the curved nose 2. The latter has an inlet C at the bottom thereof. In the housing l, behind the nose 2, is journaled the crank shaft 3 which carries at its forward end the crank pin 4. The rear end of the crank shaft 3 is operatively connected to the flexible shaft 5 with which the crank shaft 3 is rotated by a suitable electric motor (not shown).

The crank pin 4 engages into the eccentric block 6 which is mounted to slide in a suitable groove provided for this purpose in the toggle 1. The latter is mounted to oscillate on the toggle 'pin .8,1 whchfis lanchorediinylthe housing :at 9 by means ofthesetscrewil.

The nose piece A, which cooperates with the cutting mechanism, is anchored'to the frontof the rnose` Zloffthe nozzle B which 'ior'thispurposezis vcutaway-fat tliebottom `to form a seat llifor the nose 'piece` tobe adjustably seated therein. The form'o'f nose f'piece illustrated-.in Figures 1 to 4 and 6 to f8 is fprovidedwith the anchoring langefi which is slotted at |9-'|9 to have the anchoring screws pass therethrough for Ithreadedengagement into the ,wall of the nose '2. In thi's way Athenose p'iece. Amay'be rmly clamped to'the'bottom of the'noseZ and held inta vertically adjustableV positionithereon so .as ftocontrol the action of the `air 'currentsinduced by the vacuum in'the nozzle.' 1.

.Asabove pointed out'the .function oi'the nose piece is to direct, 'arrange Vand 'collect the loose ends .of threads projecting Yfrom and embedded f inithe fabriomaterial over `whichthesuction nozbleis moved an'd'then to position theseloose ends of the threads relative to thecutting mechanism so ',-that thecutting vteethwill `eilcientlyfcut off these ends and have them-carried 01Tv byithe air current induced vby the suction created in the nozzle. 4Inorder to do this efciently the nose piece --must be 'adapted or adjusted tothe particular'kindof textile material on which-the apparatus is to be used.A Furthermore to-fprevent any damage to the textile material by the cutf ting mechanism during the clipping operation, the` nose `piec'econstruction must be 'adaptedto the: dierentfweights and n the stiiiness of theVv textile material on Ywhich the clipping o rcutting operationtakesplace in order to keep the'textile Vmaterial from Vbeing raised and drawnwith Ithe loose ends of threads between thefcuttingteeth of the .cutting-blades. For example, in trimming theloose ends'of threads from very light weight textile material itis' desirable to 'use the nose piece illustrated in Figures 5, `'18 and 19 in which the supporting flange 2|A at the bottom of the nose piece is provided Awith* a shallowA slightly angular recess 6 {22 'which 'terminates ,in .the vertical groove 23 .at the inner free end ofthelanga .Thegroolve A23' ,thus L provides .a v.collecting .an'd )positioning space 'which forms 'agapdV between .the :flange yand .the tips of thegeutting. teethrs'uch asvis illustratedin vFigures 1, 2, 15 :and l0 4into wwhichathe loose ends of thread'sare-drawn:bythesuction of the nozzle .and5prepositioned for their -entry between the Acutting .teeth4 The :action of. .the clipping machine with the. nose :piece attached to the Vsuction nozzle for cooperation with thecutting blades 'is therefore 'as follows: f

'With the machine in this position the suction created within the nozzle Yoperates .to .act onfanyloo'se ends of threads :onv the textile i-materi'al that come within the area covered by .tha-recess; :22

In itsa'ctionxon` the threads the suctionv gradually :directs 'and raises'the loos'eends thereof so that'by'thetime the @outer free end of Aa thread ihas `reached the vertical groove v23 which provides ,the positioning 'space or gap 24the :threadis drawnzupwardly -thereinto 'and 'raised into a substantially :verticalor erect position therein before it-enters between the cutting teeth.

Y c

For .trimming heavy weight or stii textile material, the construction of the'nose 'piece is modi-e edby having the bottom of the nosevpiece made up of a pair'oi supporting members 25g-25 vwhich project rearwardly from kthe anchoring flange IBA, one on leach side of thefnose piece as illustratedinligures i6 and i7. rllhe-spacebetween these supporting members --is covered by the ilange' 25A, with a vertieal groove .2513, atthe rear of this fiangeyas 'shown in the nose lpiece illustrated inFigures llo and 17. `In- Figures .1, 2, `3, 6 and 7 the. space between the supporting members 2&5-263L is divided byyparallel *guide members `28A-26A. -These guidepmembers are laterally spaced to provide a .series of guide grooves V2l in the front portion of lthe bottom of the nose piece between the supporting members 26. The guide Vmembers are shorter-than the supporting members in order to provide the posi-- tioning space or gap 24 between the ends of the partitioning members and the tips of the A,teeth lof the cutting Ablades the same as with the nose piece illustrated in Figures 16, 17, 18 and 19. illustrated inFigures l, 6 and'8, the guide grooves provided by the guide members 2liA inoline from under the anchoring ange to a point where they merge into the vertical guide slots `21'at the rear of the nose piece.

y The width of the guide grooves provided in a nosepiecel depends on the weight and stiffness of the textile material on which the nose piece is to be used. Thus on light weight and flexible material the nose piece used should have narrow guide grooves and a corresponding greater num- -ber of guide members Vin order to keep such material from being raised by the suction'of the nozzle while'the loose ends ofthe threads carried thereby are drawn into the guide grooves and between the teeth of the cutting blades. For heavier textile material the nose piece used can have wider guide grooves and for very heavy and stiff material the nose piece is used which has but one large groove as illustrated in Figures 16 and 17.

The form of nose piece illustrated in Figures 16 and 17 is also used when it is desired to trim the loose threads to a predetermined length on the textile material. In performing this function the loose threads enter the space between the supporting members 25--25 and are held raised therein' in advance of their entrance between the cutting teeth. A positioning gap 24 may or may not be necessary in such case.

To avoid the necessity of using different nose pieces for different types and weight of textile material, a nose piece constructed as illustrated in Figures l2, 13, 14 and 15 may be used. In this form of nose piece the guide members and guide grooves are eliminated and the members 29 thereof support between them a screen 30 made of perforated sheet material or suitable screen forming material. This screen has its sides mounted in suitable guide channels 3l provided on the inside of the supporting members 29 near the bottom thereof, so as to span fthe open space between the supporting members.

The forward edge of the screen 30 has attached thereto a member 32 which has threaded engagement with the lead screw 33. The latter is mounted to rotate in a space between the face plate 34 and the anchoring ilange i8 of the nose piece so that rotation thereof by means of the head 35 in one or the other directions will cause the member 32, and with it the screen 30, to either move forward or back in the space between the supporting members. In this way the rear edge of the screen may be moved to increase or decrease the positioning gap between screen and the tips of the teeth of the cutting blades. This is necessary in order to adjust the nose piece for use on the type and weight of Ithread to be trimmed by the trimming machine as will hereinafter be pointed out.

The anchoring flange 18C of the nose piece illlustrated in Figures 12 to 1 5 is slotted at IBC-ISC for attachment to the nose 2 by means of the anchoring screws 20. I

Y In the use of the screen equipped nose piece the loose ends of threads are picked up and separated from the textile material just as soon as such threads reach the under side of the screen on the movement of lthe trimming machine over the textile material. The suction within the nozzle operates through the holes in the screen to draw away and thus keep separating the loose ends of threads from the textile material. When the free ends of the threads reach the end of the screen, the suction in the nozzle, acting through the positioning space or gap 24, operates to turn the raised ends of any loose threads around the edge of the screen into the positioning space or gap 24 and draws such ends into a substantially vertical or erect position ahead of the teeth of the cutting blades. Further movement of the clipping machine then causes the properly positioned threads to enter between the teeth of the cutting blades to be out olf by the cutting edges thereof. With the ends of the threads in a substantially vertical position, that is at right angles to the cutting edges of the teeth, the cut off ends of the threads are readily drawn away from the cutting blades by the suction in the nozzle so as to prevent the cutting mechanism from clogging up therewith.

To accommodate different thicknesses of threads for efficient operation of the cutting mechanism, the positioning space or gap 24 may be increased or decreased by the movement of the screen 30. This is done by turning the head 35' of the lead screw in the front of the nose piece in a clockwise or counterclockwise direction. One end of the slot in the lead screw is marked and in this Way the lead. screw may be made to point to any one of the five indicating lines 36 in the face plate 34 which according to their number indicate a predetermined spacing of the edge of the screen from the 'tips of the cutting teeth. This determines the width of the position space or gap 24 for the entry of either a heavy or light thread. The lead screw is preferably provided with a thread that will cause the screen to be moved .020 for each movement of the slot in the lead screw from one indicating line in the face plate to the other. A complete revolution ofthe screw will thus cause a movement of the free edge of the screen of .100.

In Figures 9, l0 and 1l, I have illustrated a modified form of nose piece which provides for the adjustment of' the positioning space or gap 24 for the various types and weights of threads in a modied manner. In the construction of this form of nose piece its anchoring flange 38 is clamped to the front of the nose 2 by means of the clamping bolts 39-39. Slots 40--40 in the anchoring flange through which the bolts 39 pass, permit the vertical adjustment of the anchoring ange on the nose. Projecting forwardly and rearwardly of the anchoring ange are the supporting members 4|-4l and a slide 42 is mounted on the guide pins 43-43, between these supporting members. The slide 42 is provided at the bottom and rear portion thereof with the 'guide members 44 which provide the guide grooves for the collection of the loose ends of threads and the guiding of them into the po- Sitioning gap at the rear thereof as heretofore pointed out.

The portion of the slide 42 which projects forwardly of the anchoring flange 38 is provided at the top with a transversely extending pocket 45 into which project from the front and rear the set screwsv 4646. These screws engage the front and rear face of the disc 41 which is carried by an adjusting screw 48 and rotates therewith. The adjusting screw is threaded into a bushing carried by the anchoring plate 38 and when rotated by means of its head 49, moves the disc toward or away from the anchoring ange. This movement of the disc in turn is transmitted through the set screws 48 to the slide 42 `so that this slide may be moved endwise between the :59, supporting. membersY vl--ll-l to increase or decrease-the positioning gap.v Zlibetv'veenV the ends ofithe guide members. 114..v and. the 4outer ends. of theY cutting.v teeth of the cutting! blade. as. illustrated .Figure 10.I Suitableindicating. lines i)v on the-disc;-47fserve to lshow the amount-.the positioning gap has been increased ordeereased bythe relative locationofone of these indicatv inglinestoaa fixed-.point on ythe nose piece.y
