"UNITED STATES ma! mill, I'IIIIYLVAIIA.
- mu I03 mum. ncmmnnr. 7 Application filed January 88, 1988. Serial Io. 840,84.
The object of the invention is to 'rovide improvements in certain details of t e construction and operation of textile machinery and more particularly in a type of machine used to knit tubes such as are used in the formation of certain kinds of stockings, socks, and the like.
In circular knitting machines, especially when several yarns of different size, color,
10 or material are being used, the threads which are severed and not actually being worked at a given moment are constantly 1n danger of slip ing, and in fact do often slip, free from t e single binder heretofore employed,
1 with the result that each machine requires constant tending, so-called press-offs and drop stitches occur, and the resulting tube can only be used in a finished article of second quality, or must be rejected altogether.
The object therefore is to provide an improvement in the mechanism which holds the ends of severed threads, and through which the threads of various sizes, colors, or materials are an plied to the needles.
Also, in addition to the single sprin -pressed liftable binder heretofore employe 1n con tact with a yielding cushion or platen, a second such binder is provided in addition to a plurality of resilient or auxiliary fingers,
80 which are constantly in engagement with the surface over. which the threads pass, and at all times cooperate with each other and with the liftable binders, to positively prevent the escape of a sin le thread at any time from a position accessi 1e to the needles.
A further object is to provide a beading or flange, which rises radually from the surrounding surface of e thread support, and surrounds the peripheral edge portion of the cushion or platen to protect the latter and its connection with said surface, and prevent threads from entering beneath said platen, loosening a portion of its edge, and causing the threads to sna or catch thereon instead of entering freely neath the liftable binders and a knife in proximity thereto.
With these and other ob ects in mind, the present invention comprises further details of construction and operation which are fully brought out in the following description,
when read inconjunction with the accompanying draw1ngs,in which Fig. 1 is a top plan v ew of that portion of a knitting machine involving the present invention; Fig. 2 is an elevation of the same, Fig. 3 is a fra mentary elevation of the same showing t e knife and liftable binders in raised position; ind Fig. 4 is a section on the line 4-4 of 1g. The embodiment of the invention here illustrated comprises a suitablebracket 1 by which the device is attached in suitable manher to the frame of a knitting machine, said bracket comprising an uprig t portion 2, to the under side of which is secured a r 3, adapted to mesh with and be rotated y another gear or circular rack (not shown). Upon said upright portion there is secured a disc 4, having an upwardl extending cylindrical flange 5, the radia ly outer surface 7 of which flange is a continuation of the correspondin surface of said disc, and said surface of cyllndrical shape being provided with upwardly extending parallel spurs 6 between w ch needles (not shown) are adapted to reciprocate.
Supported above the upper surface of the d1s c 4 y any suitable means is a disc 8, comprising a platform, the upper surface of which is hollowed out at one point 9 and surrounded by an n wardly extendin flange 10, which surroun sand incloses t e edge portions of ayielding cushion or platen 11 made of pig skin or other suitable'material, the outwardly directed surfaceofsaid flan e merging very gradually into the surroun ing surface of said platform disc 8, so that a thread 12 passing laterally acrosssaid platform is raised in the vicinity of the hollowed out region 9 until it passes freely over the edges of, and extends across, said platen 11. A
The upwardly extending portion 2 of the bracket 1 is furthermore provided with a laterally extending arm 13, which terminates outwardly in a second bracket 14 which extends upwardly beyond'the level of the platform 8 and u on which'is mounted ahead 15 b any suita 1e means, such for-instance as l t e spaced screws 16, said head comprising an platfor 1 ISO 8 through an integral connectmg portion 17. The head i5 is provided'wlth an angu-larly directed substantially vertically extendin surface 18,,to which a pair of indeendent Tiftable binders 19 are ivoted, said hinders being lifted s ring 20, such for instance as the wire spring siiown in Fig. 1, which at one end engages the piveal support 21 of said binders and at 1ts op oslte end extends beneath the latter.
he head is provided also with a second substantially vertically extending surface 22, to which is pivotally secured through a bolt 23 an arm 24, the free end portion 25 of which bears against the upper. surface of the respective liftable binders 19, said arm 24 also supporting in pivotal engagement the upper bifurcated portion 26 of a depending kmfeblade 27, which is maintained in engage- 'ment with the edge 28 of a segmental cutaway portion of the platform disc 8, by means of any suitable t pe of spring 29 extending between said bla c and the screw or bolt 23 or other fixed portion of the device.
In addition to the liftable binders 19, there is also secured to the surface 18 of the head 15 a lever 30 by means of a bolt 31, one end portion 32'of said lever being in normal engagement with a movable portion of the textile machine (not shown), while the opposite free end ortion 33' of said lever is ada ted to bear against the upper surface of t e free end rtion25 of the-arm 24 for a purpose hereinafter described. Also in addition to the liftable binders 19 there extend across and in yielding uniform contact with the upper surface of the latform disc 8 (held in place by the screw 7 a plurality of resilient fingers or auxiliary binders 34, the outer free ends 35 of which are turned upwardly so as to assist in permitting threads of yarn to be quickly entered beneath them. while the opposite or fixed ends of said auxiliary binders are secured beneath the bolt 7 or other suitable means. Still furthermore, a thread guide 36 has a fixed end also secured beneath the bolt 7, while its angularly directedfree end portion 37 extends outwardly beyond the limits of the spurs 6 and throughout its len th is in spacedrelation with the platform isc 8 said guide bein 'relatively stiffer than, an as its name imp ies merely designed to assist in guiding threads beneath, the yielding auxiliary binders 34.
In the operation of the device, several threads 'of yarn of differing size, color, ma-
terial, et cetera, extend across the upper surface of the disc 8 beneath the auxiliar binders 34 and also beneath the liftable inders 19, being held by the latter in frictional contact wit the corrugations 11' in the platen 11 and their freely extendin ends having been reviously sheared by t e knife blade 27.
uring the operation of the knife mechanism,
by means 0 any suitable integrail1 upward and lateral extension of the the proper thread is caught by one of the spurs 6 and drawn into operating proximity with the needles (not shown in the drawings),
the loop of said thread caught'by the spur is to the downward pressure of the free end portion 39 of a laminated spring secured beneath the bolts-or'screws 16 in the head 15 upon the oppositely directed free end portion 40 of the arm 24. Practically immediately after the rise of said liftable binders 1'9 and the blade 27 the thread before mentioned asses beneath the former and is cut by the atter, the end of said thread extending across said platen being immediately caught b and held eneath said liftable binders w ich have descended under and by virtue of the action of the lever head 33 against the combined pressures of the springs 20 and 39, after which the thread cannot become loosened from contact with said platen until said liftable bindersare again permitted to rise. Also after the liftable binders rise in each case, the auxiliary binders 34 continue to hold the thread-against the platform disc 8 and prevent its accidental removal laterally therefrom.
Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is:
1. An attachment for textile machines, comprisinga platform, a platen of relatively yielding material carried by said platform, a binder supported in pivotal relation with said platform and adapted to bear against said. laten, and a beadmg surrounding said platen and radually merging into the surface of said platform, to prevent threads from entering beneath and separating said platen from said platform.
