YARN-EXAMINING MACHINE.

Anplication filed May 12, 1922.

To all fwfwm it may concern.

Be it known that l'. FREDERICK J. SUHMUTZ. a citizen ot the United States residing at South Manchester, county of Hiertiord. State oi Connecticut. have invented a certain new and useful Improvement in Yarn-Examining hachines7 of which the ioliowingis a tull, clear, and exact description.

il! invention relates to machines that are iriarticularly adapted for use in examining yarns, threads, raw silk fibre and other strands` and has for its object to provide a novel and improved machine of thischaracter.

The several features of the invention will he clearly understood from the following' description and accompanying drawings. 1n which-n Figure 1 is a front view. partly hroken away. of a strand examininginachine emhodying the features ot' the invention in their preferred torni;

Fi 7 is a sectional View, partly in elevation, taken on the line 7 7 of Fig. 3; and

Fig. S is a sectional plan view taken on the line 8-8 of Fig. 7.

The strand examiningr machine illustrated in thc drawings is provided with a board 2, and a sci-ics ot ,Q'uides 4 for severally guidingr f: plurality oit strands 6 to the board. The hoard Q is rectangular and is rotated about iongritiulinal axis during the operation of the nizwhine. and the guides 4 are moved longitudinally of the hoard and inV timed relation to the rotation thereof to cause the strands to hc wound Vtoward the left on the hoard in separate planes so as to he convenicr-.tiy visible for the purposes of examination. A series of spring clips 5 are secured to one of the longitudinal edges of theY board Serial No. 560,485.

for conveniently securing the ends of the strands in place, the operator using one clip 'to hold the leading end oi one strand and usingr the next clip to the lett after the completion of the winding: operation to hold the other end of the strand.

The examininar hoard 2 has coaxial trunnions 7 secured on its ends. The trunnion on the left hand end ot the hoard is mounted in a fixed Ushaped hearing.r 8 on the Jframe oi' the machine and the trunnion on the other end of thc hoard is mounted in a hollow hearingr head 10 formed on the inner end of a shatt 12. A block 14 is secured on the hearingy head 10 and is provided with an inwardlv projecting wing 16 that engages a side ot the extuninimgr board, the head 10 and block '1i constitutingr a chuck to cause the hoard to rotate with the shaft 1Q. The wing` 16 *forms a flange of an angle-iron which is secured to a {iangre on the block 14 hy a bolt 17 that extends through a slot in thc latter flange to enable the wing 16 to he adjusted to accommodate different thiclc nessi-s oi hoards. ln order to secure an even winding ot thc strands on the board it is ot importance that there should he no axial movement of thc hoard duringr the winding operation. and to this end a coiled spring 18 is arranged in an axial socket in the shaft 12 and is interposed between the end of the trunnion 7 and the end wall of the socket, tir:l spriuffj urging the hoard toward the fixed hearing-4 S The inner wall of the hearing` head 1li YFor the right hand truunion 7 is made conical as shown to enable the opposite end oi the hoard to he tipped upwardlyl whenv the board `is so positioned that the wing-16 faces downwardly. so as to bring its trnnnion out of the hearingr 8 and thus permit the hoard to be easily removed from the mach inc and another boardA inserted if desired.

The thread or strand guidesd are mounted on the upper edge ot a. carrier Q0 which is in the form of a har of substantially the length of the examining hoard. The carrier is mounted and guided on flanged rollers QQ which are mounted on studs 24 secured to the frame ci' the machine` the lower edge of the carrier being vfaced with U-shaped metal strips 26 secured thereto which engage the rollers `22. The npperedge of the carrier is guided by means ot a depending lang'e 2T projertiug trom the machine trame which. engages in a Ufshaped slot in the carrier.

ln the illustrated machine means is provided tor placing' a unitorin tension on the strands as they are being delivered to the hoard. and to this end a plurality o'l' thread tensioning devices are mounted on the rar-- rier QU through which the strands severally pass. As shown. eaeh thread tension rom-- prises a pair ot opposed dises QS ha vingtheir inner faces lined with plush or similar material between which the thread passes. Ilaeh pair ot dises are mounted on a stud pin 30 secured to the Carrier and are pressed toward each other by means of a spring B2 eoiled about the stud and interposed het\veen the outer dise and a nut 34 screwthreaded on the end ot the stud. this eoustruction enablingl the tension. plaeed on the individual strands to be independently adjusted by means ot the nuts By nioimting the tension devices on the carrier 20, instead of using stationary tension devices. insures a uniform tension being placed ou each strand during the operation of the machine. En some eases as where raw sill( fibre is used. it has been tound that suliicieut tension is placed on the strands it they are passed directly from the tension dises Q8 to the guide l. but in ease a greater tension is desired a .series of porcelain studs 3G are mounted on the earrier Q0 over u'hieh the strands may he. passed one or more times to inrrease the tension.

As illustrated in Figs. l. and 2 ot' the drawings the thread. yarn or other strands may be supplied to the niaehine wound on spools which may be supported on an elongated shell' 38 secured to the trout ot' the` machine traine. the spools beineP held in plat-e on the shelt` by means ot upwardly extendinrT stud pins 40 over which the spools ari` plaeed. ln case raiv silk tilne is to he used in the machine it may` if desired` he drawn direetlv from the eoeoon. the eoeoons being plaeed in suitable rec-eplaeles on the .shelf The mechanism 'tor actuating the carrier 20 comprises a shaft 42 having one end extending through and journaled in a hear ing` 44 formed on the upper end ot a brai'iket 46 secured. to the machine trame. The inner portion ot' the shaft 42 is screw-threaded and engaged by segmental screw threads formed on the end of a hloelt 48. The hloek 4S is formed on the rear end of a plunger rod 50 which extends through a hollow bushingr 52 seeured in an aperture in the ear-- rier 20. The screw-threaded bleek 48 is pressed in operative engagement. With the screw-threaded portion of the shaft 42 hy means of a spring 54 coiled about the langer 50 and interposed between a shoulser 56 on the plunger and a shoulder 58 on the inner Wall of the bushing 52. The block is held from turl'iing movement by means of a key 6() on the plunger engaging a slot in the bushing A knob Gi? is screw-threaded on the Yforward end of the plunger. lVith this construction upon rotation of the screw-threaded shaft 42 in a counter-clockwise direction the carrier 20 will loe moved longitudinally to the lett to guide the thread as it is wound on the board`r and the carrier may be brought haelt to its initial position after the eoinpletion of the winding operation by retractingr the plunger G0 by means of the knob (l2 so as to diseors neet the bloel 48 l'roln the screw-threaded shaft The shaft 42 is thus rotatei'l hv means of a ratchet wheel G4 seeured thereon`r which is engaged by a pawl (i6 pivotally mounted on a reciprocating; plunger 6&1 The plunger 68 is mounted to slide in tu hular casing 70 and is urged rearwardly by means of a spring T2 coiled about the plunger and interposed between a head 74 secured on the rear end of the plunger and a bearingl collar TG lsecured in the easing. The plunger is moved forwardly to operate the rati-het Wheel tielby means of a cani T5S earried by the Shaft lll that arts on the head of the plunger. Through this connection between the Carrier 20 and the cam T8 the earrier is moved intermittently toward the let't to guide the thread during the winding! operation, and as illustrated the earn 78 is so shaped that each movement ot the earrier takes place as an edge ot the hoard is brought into engagement with the strands. Such intermittent traversing' of the strand guiding Carrier is t'ound to be advantagenus over a construction in which the earrier is fed continuously. as the stretches of the threads extending over the iaees ol the boards are arranged more nearly at riohl. angles to the edges of the boa rd` the defleetion of the thread takingr plaee tor the most part across the edges ot the board.

In marhiues of this character it is desir able that there should be provision for rar'v ing the. sparing ot' the eoils o1' earh strand on the hoard so as to compensate I'or illitferent thicknesses of strands. To this end the actuating meihanism 'or the earrier Q0 has provision for adjustment during; the operation of the mafhine lo vary the mil-nl, of eaeh intermittent n'ioi'emeut ol' the ear tiern As shown a rnieroineliii' slome Htl i: sereukthreaded on the forward end of the tubular easingY To and the forward end will of this sleeve is adapted to he engaged hy a stop mit 82 secured on the end ot the pluu1 ger 68 so as to limit the rearward movement of the plunger hy means of its spring1 T2.
